Description

Bearing fault detection device and method

Technical Field

The present invention relates to the technical field of bearing detection, and in particular to a bearing fault detection device and method.

Background technique

Rolling bearings are core components of rotating machinery. Due to the influence of factors such as design, installation process, operating conditions and load mutation, they will produce various defects after running for a period of time and gradually expand with subsequent use until causing bearing failure.

The invention patent with authorization announcement number CN 110261111 B discloses a rotating machinery bearing fault detection test bench, including a base, a fixed plate hinged on the base, a bracket 1 fixed on the fixed plate, a rotating cylinder rotatably arranged on the bracket 1, a channel 1 is provided in the rotating cylinder, at least one protrusion is provided in the channel 1, a sliding rod is inserted into the channel 1, a sliding groove corresponding to the protrusion is provided on the sliding rod, the sliding rod can slide in the channel 1, the rotating cylinder is connected to a driving mechanism that drives it to rotate, a fixing mechanism 1 for fixing the sliding rod is provided on the rotating cylinder, a channel 2 is provided in the sliding rod, a rotating rod 1 is inserted into the channel 2, a fixing mechanism 2 for fixing the rotating rod 1 is provided on the sliding rod 2, a plurality of round tables 1 are fixed in the channel 2, and a screw hole 1 is opened in the middle of the round table 1.

However, after actual application by technicians in this field, it was found that the above method still has some shortcomings. The most obvious one is that bearing fault detection usually occurs in the quality inspection of bearings before leaving the factory, which is used to determine the qualified rate of the batch of bearings. Therefore, a large number of tests are required. When the above device is used to test the bearings, it is necessary to perform more cumbersome manual operations, and the next bearing can only be loaded after the previous bearing has been tested and unloaded. The degree of automation is low and it consumes too much manpower. In addition, the detection efficiency is not ideal and it cannot be effectively applied to batch detection operations of bearings.

Therefore, it is necessary to invent a bearing fault detection device and method to solve the above problems.

Summary of the invention

The object of the present invention is to provide a bearing fault detection device and method. By providing a driving mechanism, a supporting mechanism, a load-carrying transposition mechanism and a clamping mechanism, the driving mechanism is used to synchronously drive the supporting mechanism and the load-carrying transposition mechanism. After the supporting mechanism is driven, the bearing to be tested is driven to rotate and rise. As the supporting mechanism continues to rise, the load-carrying transposition mechanism first triggers the supporting mechanism to complete the support of the inner ring of the bearing. The subsequent driving mechanism triggers the load-carrying transposition mechanism through the supporting mechanism to complete the clamping of the outer ring of the bearing, thereby providing conditions for the detection operation. During the detection process, the load-carrying transposition mechanism is triggered due to the continuous driving of the driving mechanism. After the subsequent supporting mechanism drives the detected bearing to complete the reset, the load-carrying transposition mechanism is triggered by the driving mechanism, thereby driving the detected bearing to be unloaded, and driving the bearing to be tested to be loaded, so as to solve the problem that a large number of bearings need to be detected in the above-mentioned background technology, and the above-mentioned device needs to perform relatively cumbersome manual operations when detecting the bearing, and the loading operation of the next bearing can only be performed after the previous bearing is detected and unloaded.

The present invention also discloses a detection method of a bearing fault detection device, which specifically comprises the following steps:

S1. Place two bearings to be tested on the inner sides of two bearing grooves respectively. Due to the obstruction of the outer ring of the bearing, the bearing cannot fall from the inner side of the bearing groove. At this time, start the driving motor. After the driving motor is started, it drives the reciprocating screw to rotate. When the reciprocating screw rotates, it drives the base to rotate through the square groove and the square shaft. When the base rotates, it drives the first column to rotate synchronously.

S2, when the reciprocating screw rotates, it drives the outer sleeve to rise synchronously. When the outer sleeve rises, the first spring and the inner sleeve drive the supporting mechanism to rise as a whole, and the side plate, the second column and the third spring drive the one-way screw to rise. During the rising process of the one-way screw, the first magnet is driven to approach the second magnet, and the threaded sleeve is driven to rotate continuously. At this time, due to the limitation of the overrunning clutch, the threaded sleeve does not rotate;

S3. As the outer plate continues to rise, the first column enters the inner side of the bearing to be tested in the right load-bearing groove. When the outer plate rises to a first threshold, the top of the base fits with the bottom of the inner ring of the bearing. Subsequently, as the outer plate continues to rise, the base drives the bearing to be tested to move up from the right load-bearing groove.

S4, when the outer sleeve plate rises to the second threshold, the top of the pressure rod contacts the bottom of the counterweight column. As the first column continues to rise, the counterweight column presses down the pressure rod. After being pressed, the pressure rod pushes the moving rod, and the moving rod drives the arc-shaped support plate to move outward. At this time, the two arc-shaped support plates stretch the second spring and move from the inner side of the bearing to the inner ring of the bearing at the same time.

S5. When the rising distance of the outer sleeve plate reaches the third threshold, the top of the first column fits with the bottom of the counterweight column. At this time, the two arc-shaped support plates support the inner ring of the bearing. At the same time, since the first column is in a continuous rotation state, the two arc-shaped support plates drive the bearing to rotate synchronously. Subsequently, as the outer sleeve plate continues to rise, the first column pushes the counterweight column upward. When the counterweight column moves upward, it drives the connecting column upward through the connecting plate. When the connecting column moves upward, it pushes the second push block through the first push block. After the second push block is pushed, it drives the clamping plate to approach the outer ring of the bearing through the push rod;

S6, when the rising distance of the outer sleeve plate reaches the fourth threshold, the top of the first push block fits with the bottom of the top plate, and at the same time, the two clamping plates clamp the outer ring of the bearing from both sides of the outer ring of the bearing, and at this time, the inner ring of the bearing drives the steel ball to rotate continuously inside the stationary outer ring of the bearing, and the detection unit collects data on the inner ring of the bearing and the steel ball during the rotation process;

S7. At this time, due to the obstruction of the top plate, the counterweight column cannot continue to rise, that is, the inner sleeve cannot continue to rise. Subsequently, as the outer sleeve continues to rise, the first spring is continuously compressed, and the side plate continues to drive the one-way screw to move upward. When the outer sleeve rises to a fifth threshold, the first magnet and the second magnet complete adsorption, and the outer sleeve moves to the top of the reciprocating thread outside the reciprocating screw. Subsequently, as the reciprocating screw continues to rotate, the outer sleeve moves downward and resets.

S8. During the downward movement of the outer plate, since the first magnet is attracted by the second magnet, the one-way screw will not move downward synchronously with the outer plate, and the third spring is continuously stretched. When the outer plate descends to a sixth threshold, the current bearing detection is completed, and the compressed first spring is restored. When the outer plate descends to a seventh threshold, the first column moves to the bottom of the rotating disk. At this time, the bearing that has completed the detection falls back into the right bearing groove and is stored. At the same time, the third spring is stretched to the limit. Subsequently, as the outer plate continues to descend, the first magnet is separated from the second magnet. At this time, the stretched third spring drives the one-way screw to move downward and reset. During the downward movement of the one-way screw, it drives the threaded sleeve to rotate. When the threaded sleeve rotates, it drives the rotating disk to rotate continuously, and finally the two bearings complete the position exchange, thereby synchronously completing the loading and unloading operations.

S9. When the outer sleeve plate descends to the eighth threshold, the outer sleeve plate moves to the lowest end of the reciprocating thread on the outside of the reciprocating screw, that is, the initial position. Subsequently, as the reciprocating screw continues to rotate, the outer sleeve plate moves up again, and then the above operation is repeated. During this process, the bearing after inspection in the left load-bearing groove is removed, and then the bearing to be inspected is replaced.

Technical effects and advantages of the present invention:

The present invention is provided with a driving mechanism, a supporting mechanism, a load-bearing transposition mechanism and a clamping mechanism, so that the driving mechanism can be used to synchronously drive the supporting mechanism and the load-bearing transposition mechanism. After the supporting mechanism is driven, it drives the bearing to be tested to rotate and rise. As the supporting mechanism continues to rise, the load-bearing transposition mechanism first triggers the supporting mechanism to complete the support of the inner ring of the bearing. The subsequent driving mechanism triggers the load-bearing transposition mechanism through the supporting mechanism to complete the clamping of the outer ring of the bearing, thereby providing conditions for the detection operation. During the detection process, the load-bearing transposition mechanism is triggered due to the continuous driving of the driving mechanism. After the subsequent supporting mechanism drives the bearing after detection to complete the reset, the load-bearing transposition mechanism is triggered by the driving mechanism, thereby driving the bearing after detection to unload, and at the same time drives the bearing to be detected to load. Compared with the same type of devices and methods in the prior art, the present invention has a higher degree of automation and effectively reduces the detection difficulty and saves manpower. It can also further improve the detection efficiency and is more suitable for batch detection operations of bearings before leaving the factory.

As shown in Figure 4, the supporting mechanism 3 includes a base 31, a square shaft 32, a first column 33, a pressure rod 34, an arc-shaped supporting plate 35, a moving rod 36 and a second spring 37, wherein the base 31 is fixedly arranged on the top of the inner sleeve 25, the square shaft 32 is slidably arranged on the inner side of the square groove 23 and is fixedly connected to the base 31, the first column 33 is fixedly arranged on the top of the base 31, the pressure rod 34 is slidably arranged on the inner top of the first column 33, two arc-shaped supporting plates 35 and two moving rods 36 are each provided, and the two arc-shaped supporting plates 35 are respectively nested at the bottom of both sides of the first column 33, and the two moving rods 36 are respectively fixedly arranged on the inner sides of the two arc-shaped supporting plates 35 and both slide through the side wall of the first column 33 and extend to the inner side of the first column 33 and slide in contact with the bottom of the pressure rod 34, and the second spring 37 is fixedly connected between the two arc-shaped supporting plates 35.

By setting the above structure, after the top end of the pressure rod 34 contacts the bottom end of the counterweight column 51, as the first column 33 continues to rise, the counterweight column 51 presses down the pressure rod 34. After being pressed, the pressure rod 34 pushes the moving rod 36, and the moving rod 36 drives the arc support plate 35 to move outward. At this time, the two arc support plates 35 stretch the second spring 37 and approach the inner ring of the bearing from the inner side of the bearing until the inner ring of the bearing is supported by the inner side of the inner ring of the bearing.

As shown in FIG5 , the load-carrying transposition mechanism 4 includes a rotating disk 41, a load-carrying groove 42, an avoidance channel 43, a threaded sleeve 44, a one-way screw 45, a third spring 46, a second column 47, a first magnet 48 and a second magnet 49, wherein the rotating disk 41 is rotatably nested on the left side of the top of the box body 11 through a bearing, two load-carrying grooves 42 and two avoidance channels 43 are provided, two load-carrying grooves 42 are respectively opened at two tops of the rotating disk 41, and two avoidance channels 43 are respectively penetrated and arranged on the inner sides of the two load-carrying grooves 42, the threaded sleeve 44 is connected to the inner side of the rotating disk 41 through an overrunning clutch, the one-way screw 45 is threadedly connected to the inner side of the threaded sleeve 44, the third spring 46 is fixedly connected between the one-way screw 45 and the second column 47, the second column 47 is fixedly arranged on the top of the side plate 28, the first magnet 48 is fixedly arranged on the top of the one-way screw 45, and the second magnet 49 is located directly above the first magnet 48 and fixedly arranged on the bottom of the top plate 13.

By setting the above structure, two bearings to be tested can be placed inside the two bearing grooves 42 respectively. Due to the obstruction of the outer ring of the bearing, the bearing cannot fall from the inside of the bearing groove 42. In addition, when the outer sleeve 27 rises, the side plate 28, the second column 47 and the third spring 46 drive the one-way screw 45 to rise. During the rising process of the one-way screw 45, the first magnet 48 is driven to approach the second magnet 49, and the threaded sleeve 44 is driven to rotate continuously. At this time, due to the limitation of the overrunning clutch, the threaded sleeve 44 does not rotate.

Subsequently, when the first magnet 48 and the second magnet 49 complete adsorption and the outer sleeve 27 moves downward, since the first magnet 48 is adsorbed by the second magnet 49, the one-way screw 45 will not move downward synchronously with the outer sleeve 27, and the third spring 46 is continuously stretched. When the third spring 46 is stretched to the limit, as the outer sleeve 27 continues to descend, the first magnet 48 and the second magnet 49 are separated. At this time, the stretched third spring 46 drives the one-way screw 45 to move downward and reset. During the downward movement of the one-way screw 45, it drives the threaded sleeve 44 to rotate. When the threaded sleeve 44 rotates, it drives the rotating disk 41 to rotate continuously, and finally the two bearings complete the position exchange, thereby synchronously completing the loading and unloading operations.

As shown in Figure 6, the clamping mechanism 5 includes a counterweight column 51, a connecting plate 52, a connecting column 53, a first push block 54, a second push block 55, a push rod 56, a clamping plate 57, a fourth spring 58 and a fixed plate 59, wherein the counterweight column 51 slides through the top plate 13 and is located directly above the first column 33, the connecting plate 52 is rotatably arranged at the top of the counterweight column 51 through a bearing, the connecting column 53 slides through the top plate 13 and is fixedly connected to the connecting plate 52, the first push block 54 is fixedly arranged at the bottom end of the connecting column 53, the second push block 55 slides and fits the inner side of the first push block 54, the push rod 56 is fixedly connected to the inner side of the second push block 55, the clamping plate 57 is fixedly arranged at the end of the push rod 56, the fourth spring 58 is sleeved on the outside of the push rod 56 and is fixedly connected between the second push block 55 and the fixed plate 59, and the fixed plate 59 is slidably sleeved on the outside of the push rod 56 and is fixedly connected to the top plate 13.

By setting the above structure, when the first column 33 subsequently lifts the counterweight column 51 upward, the counterweight column 51 drives the connecting column 53 to move upward through the connecting plate 52. When the connecting column 53 moves upward, the second push block 55 is pushed by the first push block 54. After being pushed, the second push block 55 drives the clamping plate 57 to approach the outer ring of the bearing through the push rod 56. When the top of the first push block 54 is in contact with the bottom of the top plate 13, the two clamping plates 57 clamp the outer ring of the bearing from both sides of the outer ring of the bearing. At this time, the inner ring of the bearing drives the steel ball to rotate continuously on the inner side of the stationary outer ring of the bearing, and the detection unit collects data on the inner ring of the bearing and the steel ball during rotation.

Example 2

The present invention also discloses a detection method of a bearing fault detection device, which specifically comprises the following steps:

S1. Place two bearings to be tested inside two bearing grooves 42 respectively. Due to the obstruction of the outer ring of the bearing, the bearing cannot fall from the inside of the bearing groove 42. At this time, start the drive motor 24. After the drive motor 24 is started, it drives the reciprocating screw 22 to rotate. When the reciprocating screw 22 rotates, it drives the base 31 to rotate through the square groove 23 and the square shaft 32. When the base 31 rotates, it drives the first column 33 to rotate synchronously.

S2. When the reciprocating screw 22 rotates, it drives the outer sleeve 27 to rise synchronously. When the outer sleeve 27 rises, it drives the supporting mechanism 3 to rise as a whole through the first spring 26 and the inner sleeve 25, and drives the one-way screw 45 to rise through the side plate 28, the second column 47 and the third spring 46. During the rising process of the one-way screw 45, it drives the first magnet 48 to approach the second magnet 49, and drives the threaded sleeve 44 to rotate continuously. At this time, due to the limitation of the overrunning clutch, the threaded sleeve 44 does not rotate;

S3, as the outer plate 27 continues to rise, the first column 33 enters the inner side of the bearing to be tested in the right bearing groove 42. When the outer plate 27 rises to a first threshold, the top of the base 31 fits with the bottom of the inner ring of the bearing. Subsequently, as the outer plate 27 continues to rise, the base 31 drives the bearing to be tested to move up from the right bearing groove 42.

S4, when the outer sleeve plate 27 rises to a second threshold, the top of the pressure rod 34 contacts the bottom of the counterweight column 51. As the first column 33 continues to rise, the counterweight column 51 presses down the pressure rod 34. After being pressed, the pressure rod 34 pushes the moving rod 36. The moving rod 36 drives the arc-shaped support plate 35 to move outward. At this time, the two arc-shaped support plates 35 stretch the second spring 37 and move from the inner side of the bearing to the inner ring of the bearing.

S5. When the rising distance of the outer sleeve plate 27 reaches the third threshold, the top of the first column 33 fits with the bottom of the counterweight column 51. At this time, the two arc-shaped support plates 35 support the inner ring of the bearing. At the same time, since the first column 33 is in a continuous rotation state, the two arc-shaped support plates 35 drive the bearing to rotate synchronously. Subsequently, as the outer sleeve plate 27 continues to rise, the first column 33 pushes the counterweight column 51 upward. When the counterweight column 51 moves upward, it drives the connecting column 53 upward through the connecting plate 52. When the connecting column 53 moves upward, it pushes the second push block 55 through the first push block 54. After being pushed, the second push block 55 drives the clamping plate 57 to approach the outer ring of the bearing through the push rod 56;

S6, when the rising distance of the outer sleeve plate 27 reaches the fourth threshold, the top of the first push block 54 fits with the bottom of the top plate 13, and at the same time, the two clamping plates 57 clamp the outer ring of the bearing from both sides of the outer ring of the bearing. At this time, the inner ring of the bearing drives the steel ball to rotate continuously inside the stationary outer ring of the bearing, and the detection unit collects data on the inner ring of the bearing and the steel ball during the rotation process;

S7. At this time, due to the obstruction of the top plate 13, the counterweight column 51 cannot continue to rise, that is, the inner sleeve 25 cannot continue to rise. Subsequently, as the outer sleeve 27 continues to rise, the first spring 26 is continuously compressed, and at the same time, the side plate 28 continues to drive the one-way screw 45 to move upward. When the rising distance of the outer sleeve 27 reaches the fifth threshold, the first magnet 48 and the second magnet 49 complete the adsorption, and at the same time, the outer sleeve 27 moves to the top of the reciprocating thread outside the reciprocating screw 22. Subsequently, as the reciprocating screw 22 continues to rotate, the outer sleeve 27 moves down and resets.

S8, during the downward movement of the outer sleeve plate 27, since the first magnet 48 is attracted by the second magnet 49, the one-way screw 45 will not move downward synchronously with the outer sleeve plate 27, and the third spring 46 is continuously stretched. When the outer sleeve plate 27 descends a distance that reaches the sixth threshold, the current bearing detection is completed, and the compressed first spring 26 is restored. When the outer sleeve plate 27 descends a distance that reaches the seventh threshold, the first column 33 moves to the bottom of the rotating disk 41. At this time, the bearing that has completed the detection falls back into the right bearing groove 42 and is accommodated. At the same time, the third spring 46 is stretched to the limit. Subsequently, as the outer sleeve plate 27 continues to descend, the first magnet 48 and the second magnet 49 are separated. At this time, the stretched third spring 46 drives the one-way screw 45 to move downward and reset. During the downward movement of the one-way screw 45, it drives the threaded sleeve 44 to rotate. When the threaded sleeve 44 rotates, it drives the rotating disk 41 to rotate continuously, and finally the two bearings complete the position exchange, thereby synchronously completing the loading and unloading operations.

S9. When the outer sleeve plate 27 descends to the eighth threshold, the outer sleeve plate 27 moves to the lowest end of the reciprocating thread on the outside of the reciprocating screw 22, that is, the initial position. Subsequently, as the reciprocating screw 22 continues to rotate, the outer sleeve plate 27 moves up again, and then the above operation is repeated. During this process, the bearing after inspection in the left load-bearing groove 42 is removed, and then the bearing to be inspected is replaced.

Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
