Description

A high-precision rotating mechanism for ultrasonic detection of bearing rollers

Technical Field

The invention relates to the technical field of production of roller flaw detection equipment, and more specifically to a high-precision rotating mechanism for ultrasonic detection of bearing rollers.

Background technique

During the roller ultrasonic testing process, the roller needs to rotate 360 degrees, and the ultrasonic probe scans along the axis. Currently, the common rotation methods are top clamping rotation and roller friction rotation. Among them, the roller material in the roller friction rotation is generally PEEK material. When this material drives the roller to rotate, it often embeds some impurities, thereby scratching the product. In the existing technology, some companies choose to cover the roller with a layer of soft material to protect the roller. However, in actual use, since the roller flaw detection is carried out in water, most soft materials are easy to deform in water, resulting in a large amplitude of the roller jumping when rotating 360°, which is difficult to meet the needs of roller flaw detection accuracy.

A plurality of contact sensors are fixed to the bottom of the detection station, and when the roller is placed on the detection station, the protective material holds up the roller so that a safe distance is maintained between the roller and the contact sensor.

Furthermore, the protective material is rubber, and a plurality of contact sensors are fixed to the bottom of the detection station. When the roller is placed on the detection station, the protective material holds up the roller so that a safe distance is maintained between the roller and the contact sensors.

Furthermore, the surface of the drum is protruded with a plurality of framework bodies, and the protective material is detachably coated and attached to the framework bodies.

Furthermore, the above-mentioned skeleton body is an arc-shaped protrusion surrounding the surface of the drum, and the arc surfaces on both sides of the arc-shaped protrusion are provided with surrounding pressure grooves, the inclination direction of the pressure grooves is toward directly above the avoidance grooves, and the inside of the pressure grooves is provided with pressure strips that can be interference-locked, and the pressure strips press the protective material tightly and wrap it around the arc-shaped protrusion.

Detailed ways

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

As shown in Figure 1, a specific embodiment of the present invention, the structure of which includes a base 1, a plurality of rotatable rollers 11 are provided on the base 1, the plurality of rollers 11 are evenly arranged side by side on the base 1, a roller detection station 12 is formed between two adjacent rollers 11, a plurality of elastically deformable protective materials 13 are protruded from the surface of the roller 11, the plurality of protective materials 13 are arranged side by side on the surface of the roller 11, an avoidance groove 14 is formed between two adjacent protective materials 13, a plurality of contact sensors 2 are fixed to the bottom of the detection station 12, when the roller is placed on the detection station 12, the protective material 13 holds up the roller so that a safe distance is maintained between the roller and the contact sensor 2.

In the present invention, the roller to be inspected is placed on the inspection station 12, and the protective material 13 supports the roller so that the roller can be kept away from the surface of the drum 11 in the avoidance groove 14. When the roller is inspected, the rotation of the drum 11 can prevent the roller 11 from scratching the roller, thereby protecting the roller.

In the present invention, as a preferred solution, the protective material 13 is rubber, and a plurality of contact sensors 2 are fixed to the bottom of the detection station 12. When the roller is placed on the detection station 12, the protective material 13 holds up the roller so that a safe distance is maintained between the roller and the contact sensor 2.

In the present invention, the protective material 13 is rubber, which is relatively soft and can avoid damage to the roller. However, the roller flaw detection in the present invention is carried out in water. Rubber is easily deformed after being immersed in water for a long time. In the present invention, avoidance grooves 14 are set between two adjacent protective materials 13, indicating that the protective material 13 in the present invention is not flat on the roller 11. This setting can reduce the deformation area of the protective material 13, thereby reducing the amplitude of the roller jumping on the detection station 12, and improving the accuracy of roller detection.

In the present invention, when the protective material 13 is deformed, in order to be able to judge whether the accuracy of roller flaw detection meets the requirements, when the amplitude of the roller jumping at the detection station 12 exceeds a certain range, preferably, this safety distance is 0.01mm-0.03mm, the roller will contact the contact sensor 2 at the detection station 12, and the contact sensor 2 will sense the pressure and send a signal to the outside world, indicating that the protective material 13 has been excessively deformed and needs to be replaced.

In the present invention, generally speaking, the easier it is to disassemble and install, the easier it is for the installation position of the protective material 13 to leak water, and the easier it is for the installation position to leak water, the easier it is for the protective material 13 to deform, that is, the shorter the service life of the protective material 13. The present invention lists two installation structures: Example 1 and Example 2, which correspond to different installation difficulties and service lives of the protective material 13, respectively. Users can choose a suitable installation structure according to their needs.

Embodiment 1

As shown in FIG. 2 to FIG. 4 , in this embodiment, as a preferred solution, the surface of the drum 11 is provided with a plurality of framework bodies, and the protective material 13 is detachably coated and attached to the framework bodies.

In this embodiment, the frame body can support the protective material 13, so as to avoid the roller still contacting the surface of the drum 11 at the position of the avoidance groove 14 after the protective material 13 is deformed, which provides the best protection for the roller. Secondly, the protective material 13 needs to be wrapped and installed according to the structure of the frame body. This wrapped installation can make the protective material 13 fit on the frame body. Although the installation structure needs to be installed according to the structure of the frame body and the installation process is complicated, the frame body and the protective material 13 fit together. On the one hand, the support of the frame body can also reduce the degree of deformation of the protective material 13. Secondly, the fit between the protective material 13 and the frame body can also prevent external water from penetrating into the interior of the protective material 13, thereby extending the service life of the protective material 13.

In this embodiment, as a preferred solution, the above-mentioned skeleton body is an arc-shaped protrusion 3 surrounding the surface of the roller 11, and the arc surfaces on both sides of the arc-shaped protrusion 3 are provided with surrounding pressing grooves 31, and the inclination direction of the pressing groove 31 is toward the top of the avoidance groove 14. The interior of the pressing groove 31 is provided with a pressure strip 32 that can be interference-locked, and the pressure strip 32 presses the protective material 13 tightly and covers the arc-shaped protrusion 3.

In this embodiment, the method of coating the protective material 13 on the frame body is as follows:

First, the protective material 13 is wrapped around the arc-shaped protrusion 3 , and both sides of the protective material 13 extend to the bottom of the avoidance groove 14 .

A rotatable ball is used to press the protective material 13 into the pressing groove 31, and the ball is rolled along the pressing groove 31, so that the protective material 13 is pressed tightly into the pressing groove 31. Since the pressing groove 31 in the present invention is tilted upward, it will not be affected by the avoidance groove 14 during the specific operation, and the whole operation process is simple and convenient.

The pressing strip 32 is inserted into the pressing groove 31 by interference fit, so that the protective material 13 is pressed and wrapped around the arc-shaped protrusion 3 .

The protective material 13 leaking out of the pressing groove 31 is cut off.

In this embodiment, as a preferred solution, two arc-shaped protrusions 3 are symmetrically arranged on the arc surfaces on both sides of the arc-shaped protrusion 3, the arc surface on the top of the arc-shaped protrusion 3 is provided with an inwardly recessed groove 4, and the bottom of the protective material 13 is provided with a downwardly protruding block 41, and the block 41 is stuck in the inside of the groove 4 and cooperates with the pressure strip 32 so that the protective material 13 fits tightly on the arc-shaped protrusion 3.

In the embodiment, the protrusion 41 is stuck in the inside of the slot 4 as a point where the protective material 13 and the arc-shaped protrusion 3 are fitted together, and the two pressure strips 32 symmetrically press the protective material 13 on both sides of the arc-shaped protrusion 3 as the other two points. These three points press down the protective material 13 at the same time, ensuring that the protective material 13 is tightly fitted on the arc-shaped protrusion 3.

In the present invention, as a preferred solution, the inner wall of the above-mentioned slot 4 is provided with a plurality of inner slopes 5 inclined downward, and a lower hook groove 51 is formed between the plurality of inner slopes 5; the outer wall of the protrusion 41 is provided with a plurality of outer slopes 52 inclined upward, and an upper hook groove 53 is formed between the plurality of outer slopes 52; the lower hook groove 51 cooperates with the upper hook groove 53 to fix the protrusion 41 inside the slot 4.

In this embodiment, the protrusion 41 is embedded in the slot 4, and the lower hook groove 51 can hook the upper hook groove 53, so that the protrusion 41 can be stably stuck in the slot 4, thereby further ensuring the stability of the protective material 13 fitting on the arc-shaped protrusion 3.

In this embodiment, although the installation process of the protective material 13 on the arc-shaped protrusion 3 is relatively complicated, the arc-shaped protrusion 3 provides a close support for the protective material 13, thereby reducing the penetration of external water into the interior of the protective material 13, so that the protective material 13 in this embodiment is not easily deformed in water, thereby extending the service life of the protective material 13.

Embodiment 2

As shown in FIG. 5 and FIG. 6 , in this embodiment, as a preferred solution, a plurality of annular grooves 6 are formed on the drum 11 , and an O-ring 61 is fixed on the annular groove 6 , and the O-ring 61 protrudes from the surface of the drum 11 .

In this embodiment, when installing the O-ring 61, it is only necessary to embed the O-ring 61 directly into the inside of the annular groove 6. The installation process is relatively simple, but corresponding external water can easily penetrate into the inside of the annular groove 6. Compared with embodiment 1, the service life of the O-ring 61 is lower.

In this embodiment, as a preferred solution, the open end of the annular groove 6 is surrounded by two symmetrical spherical protrusions 7, the bottom of the O-ring 61 is provided with a connecting block 8 embedded in the annular groove 6, and the O-ring 61 is supported on the top of the spherical protrusion 7.

In this embodiment, when the connecting block 8 is embedded in the annular groove 6, the setting of the spherical protrusion 7 can prevent employees from touching the quick opening of the annular groove 6, thereby preventing employees from being injured when installing the O-ring 61. Secondly, the spherical protrusion 7 can also support the O-ring 61.

In this embodiment, as a preferred solution, symmetrical wrapping surfaces 81 are provided on both sides of the O-ring 61 , and the wrapping surfaces 81 are used to wrap the spherical protrusion 7 .

In this embodiment, the wrapping surface 81 wraps around the spherical protrusion 7, which can position the supporting position of the O-ring 61 on the spherical protrusion 7, thereby preventing the O-ring 61 from being offset during installation.

Regardless of Embodiment 1 or Embodiment 2, when the protective material 13 needs to be removed later, it means that the protective material 13 has been deformed, and the deformed protective material 13 can be easily removed.
