Examples

The embodiment provides a transverse hole detector.

Referring to fig. 1-2, the cross hole inspection machine includes a feeding device 100, a positioning device Kong Zhengliao, 200, and a positioning device 300.

Wherein the feeder 100 is used for providing a workpiece 1000 to be inspected with a transverse hole 1100. The Kong Zhengliao device 200 is connected to the feeding device 100, and is used for detecting the position of the transverse hole 1100 and adjusting the position of the workpiece 1000 to be detected according to the detection result. The positioning and detecting device 300 is connected to the positioning and Kong Zhengliao device 200, and is used for positioning the workpiece 1000 to be detected and detecting the positioned workpiece 1000 to be detected.

In this way, due to the arrangement of the feeding device 100, the Kong Zhengliao device 200 and the positioning and detecting device 300, the feeding device 100 mainly realizes the automatic feeding of the workpiece 1000 to be detected, the Kong Zhengliao device 200 receives the workpiece 1000 to be detected conveyed from the feeding device 100, and adjusts the position of the workpiece 1000 to be detected, so that the workpiece 1000 to be detected can be conveyed to the positioning and detecting device 300 in the same position state, and the positioning and detecting device 300 completes the positioning and detection of the workpiece 1000 to be detected.

In some embodiments, the feeding device 100 may select a vibration plate, so that the workpiece 1000 to be inspected may be conveyed into the device 200 according to Kong Zhengliao by the action of the vibration plate.

In addition, in other embodiments, the feeding device 100 may also select a belt or the like to enable automated transportation of the workpiece 1000 to be inspected. It will be appreciated that, in order to ensure that the workpiece 1000 to be inspected enters the apparatus 200 of Kong Zhengliao in a orderly manner, a limit groove for limiting the workpiece 1000 to be inspected may be provided on the belt.

Referring to fig. 1-3 in combination, the device 200 for locating Kong Zhengliao includes a guide rail 210, a locating mechanism 220, and a monolith mechanism 230.

The guide rail 210 is used for transporting the workpiece 1000 to be inspected with the transverse hole 1100. The hole finding mechanism 220 is mounted on the guide rail 210 for detecting the position of the transverse hole 1100. The arranging mechanism 230 is mounted on the guide rail 210 and is located behind the hole finding mechanism 220, and is used for adjusting the position of the workpiece 1000 to be detected according to the position of the transverse hole 1100.

It can be appreciated that the guide rail 210 is engaged with the feeding device 100, that is, the workpiece 1000 to be detected is transported from the feeding device 100 to the guide rail 210, then the guide rail 210 transports the workpiece 1000 to be detected to the hole locating mechanism 220, the hole locating mechanism 220 detects the position of the transverse hole 1100, so as to obtain the position of the workpiece 1000 to be detected, then the workpiece 1000 to be detected is transported to the arranging mechanism 230, and the arranging mechanism 230 determines whether the position adjustment of the workpiece 1000 to be detected is necessary according to the position of the workpiece 1000 to be detected.

The workpiece 1000 to be detected can be uniformly combed through the functions of the hole finding mechanism 220 and the arranging mechanism 230, so that all the workpieces 1000 to be detected enter the next process in the same position state, the efficiency is improved, and the labor is saved.

With continued reference to fig. 3, in one embodiment, the guide rail 210 is disposed obliquely, and a higher end of the guide rail is connected to the feeding device 100, so that the workpiece 1000 to be inspected after exiting from the feeding device 100 can be autonomously transferred to the hole searching mechanism 220 and the arranging mechanism 230.

The hole finding mechanism 220 includes a first sensor 221 disposed at least one end of the workpiece 1000 to be inspected for detecting whether the end has a transverse hole 1100. For example, a first sensor 221 may be provided at the rear end of the workpiece 1000 to be inspected (with respect to the inclined arrangement of the rail 210, it may be understood that the lower end of the workpiece 1000 to be inspected) to indicate that the workpiece 1000 to be inspected is positioned on the rail 210 with the transverse hole 1100 at the rear end once the first sensor 221 senses the transverse hole 1100, and that the workpiece 1000 to be inspected is positioned on the rail 210 with the transverse hole 1100 at the front end if the transverse hole 1100 is not sensed. For another example, a first sensor 221 may be disposed at the front end of the workpiece 1000 to be inspected, and the position of the workpiece 1000 to be inspected may be determined in a similar manner to the former. For example, a first sensor 221 may be disposed at two ends of the workpiece 1000 to be detected, where the first sensors 221 at different positions reflect different position information, and when the first sensor 221 at the front end senses the transverse hole 1100, it indicates that the workpiece 1000 to be detected is located on the guide rail 210 in a manner that the transverse hole 1100 is at the front end, and when the first sensor 221 at the rear end senses the transverse hole 1100, it indicates that the workpiece 1000 to be detected is located on the guide rail 210 in a manner that the transverse hole 1100 is at the rear end.

In some embodiments, the first sensor 221 may be a fiber optic sensor, and may be detected by the fiber optic sensor once the transverse hole 1100 is opposite to the fiber optic sensor.

It will be appreciated that in some cases, the transverse hole 1100 in the workpiece 1000 to be inspected may not be facing the fiber optic sensor, and as a result, the existence of the transverse hole 1100 may not be sensed or sensing inaccuracy may occur.

In this regard, referring to fig. 4 in combination, the hole searching mechanism 220 further includes a driving wheel assembly 222, where the driving wheel assembly 222 is disposed below the guide rail 210, and the driving wheel assembly 222 can act on the outer wall of the workpiece 1000 to be inspected, so that the workpiece 1000 to be inspected rotates.

In this way, the transverse bore 1100 is eventually rotated into position against the fiber optic sensor by the action of the drive wheel assembly 222.

Further, the driving wheel assembly 222 includes a first driving motor 2221 and a friction wheel 2222 mounted on the first driving motor 2221, and the friction wheel 2222 is supported below the workpiece 1000 to be inspected, so that the friction wheel 2222 can be applied to the workpiece 1000 to be inspected.

It should be noted that the number of friction wheels 2222 may be determined according to requirements, for example, in the example shown in fig. 4, two friction wheels 2222 are provided. It will be appreciated that the arrangement of the two friction wheels 2222 corresponds to a reduction mechanism constructed to ensure stable rotation of the workpiece 1000 to be inspected.

In some embodiments, friction wheel 2222 may be made of rubber to minimize the impact on the outer wall of workpiece 1000 to be inspected.

In some embodiments, the hole finding mechanism 220 further includes a limiting component 223, where the limiting component 223 includes a first limiting member 2231, and the first limiting member 2231 is located behind the first sensor 221, and the first limiting member 2231 is movably mounted on the guide rail 210, so that the first limiting member 2231 can extend into the guide rail 210 and withdraw from the guide rail 210, so as to limit the workpiece 1000 to be detected, thereby facilitating the detection of the transverse hole 1100 by the first sensor 221.

Because of the existence of the first limiting member 2231, the workpiece 1000 to be inspected can be suspended at the first limiting member 2231 during transportation, and the workpiece is supported by the first limiting member 2231, and the inspection of the transverse hole 1100 can be completed by combining the functions of the driving wheel assembly 222 and the optical fiber sensor. After the inspection is completed, the first stopper 2231 is withdrawn from the guide rail 210 so that the work 1000 to be inspected is conveyed to the monolith mechanism 230.

Further, the limiting assembly 223 may further include a second limiting member 2232, where the second limiting member 2232 is movably mounted on the guide rail 210, so that the second limiting member 2232 can extend into the guide rail 210 and withdraw from the guide rail 210, and a distance between the second limiting member 2232 and the first limiting member 2231 is at least greater than a length of the workpiece 1000 to be inspected, so that a workpiece 1000 to be inspected can be accommodated between the second limiting member 2232 and the first limiting member 2231.

In this way, a relatively independent area can be formed between the first limiter 2231 and the second limiter 2232 through the action of the first limiter 2231, only one workpiece 1000 to be detected can exist in the area, meanwhile, the driving wheel assembly 222 is located just below the area, and the optical fiber sensor is arranged at the rearmost end of the area, so that during detection, only one workpiece 1000 to be detected is detected at a time, and the detection effect on the transverse hole 1100 can be improved to a certain extent.

Further, the limiting assembly 223 may further include a third limiting member 2233, where the first limiting member 2231, the second limiting member 2232, and the third limiting member 2233 are sequentially disposed on the guide rail 210 from back to front, and the third limiting member 2233 is movably mounted on the guide rail 210, so that the third limiting member 2233 can be abutted to the outer wall of the workpiece 1000 to be detected, and a distance between the third limiting member 2233 and the second limiting member 2232 is greater than a length of the workpiece 1000 to be detected, so that the second limiting member 2232 is limited behind the workpiece 1000 to be detected, and the third limiting member 2233 is abutted to the outer wall of the workpiece 1000 to be detected.

In this way, by the action of the first stopper 2231 and the second stopper 2232, it is ensured that only one workpiece 1000 to be inspected is transferred into the relatively independent area formed by the first stopper 2231 and the second stopper 2232 at a time. Specifically, when the workpiece 1000 to be inspected in the above-mentioned area is still in the inspection process, the second stopper 2232 is limited behind the previous workpiece 1000 to be inspected of the workpiece 1000 to be inspected still in the inspection process, and the third stopper 2233 is abutted against the outer wall of the workpiece 1000 to be inspected yet further, for convenience of description, the three workpieces 1000 to be inspected are sequentially referred to as a first workpiece to be inspected, a second workpiece to be inspected and a third workpiece to be inspected from the back to the front, when the inspection is completed, the first stopper 2231 is withdrawn, the first workpiece to be inspected is transferred to the monolith 230, then the first stopper 2231 is again inserted into the guide rail 210, then the second stopper 2232 is withdrawn, the second workpiece to be inspected is transferred to the first stopper 2231, then the second stopper 2232 is again inserted into the guide rail 210, and thereafter, the third stopper 2233 is withdrawn, so that the third workpiece to be inspected is transferred to the second stopper 2232, and finally the third stopper 2233 is again inserted, and each inspection of the workpieces 1000 is completed by the above cycle.

In this way, under the action of the first limiter 2231, the second limiter 2232 and the third limiter 2233, only one workpiece 1000 to be detected is transported to the first limiter 2231 at a time, so that the detection of the workpiece 1000 to be detected is ensured to be performed stably and orderly.

Of course, in other embodiments, the above-described effect can be achieved by the combination of the first stopper 2231 and the third stopper 2233, except that the above-described relatively independent regions are not formed at this time, but the effects are substantially the same.

In some embodiments, the first, second and third stoppers 2231, 2232 and 2233 can be driven by a cylinder, and the first, second and third stoppers 2231, 2232 and 2233 can themselves be rods driven by the cylinder to extend into or retract from the guide rail 210.

In other embodiments, the first limiter 2231, the second limiter 2232, and the third limiter 2233 can be implemented using electric push rods.

In addition to the guide rail 210 described above, in another embodiment, the guide rail 210 may be disposed horizontally, where the guide rail 210 may be disposed in a manner of a belt, and a position sensor is disposed at a corresponding position, and the position sensor guides the operation of the belt, so as to realize stable transportation of the workpiece 1000 to be inspected.

With continued reference to fig. 3, the sorting mechanism 230 includes a rotary tray 231 rotatably disposed on the guide rail 210, and the rotary tray 231 is used for exchanging the position of the workpiece 1000 to be inspected.

It will be appreciated that, after the workpiece 1000 to be inspected is transported to the sorting mechanism 230, if the transported workpiece 1000 to be inspected needs to be subjected to position exchange, the rotating tray 231 is controlled to rotate 180 degrees.

The monolith mechanism 230 further includes a driving motor to which the rotary tray 231 is coupled, and the rotation of the rotary tray 231 is driven by the driving motor. It will be appreciated that in order to effect rotation of the swing tray 231, this may also be effected by a rotary cylinder 232, for example in the example shown in fig. 2, the rotary cylinder 232 being supported below the swing tray 231 for controlling rotation of the swing tray 231.

Further, in order to ensure smooth operation of the rotary tray 231, the arranging mechanism 230 further includes a fourth limiting member 233, where the fourth limiting member 233 is used to limit the position of the workpiece 1000 to be detected, so that the rotary tray 231 performs position exchange on the workpiece 1000 to be detected.

In other words, similar to the first limiting member 2231 described above, if the workpiece 1000 to be detected needs to be subjected to the position exchange, the workpiece 1000 to be detected temporarily exists in front of the fourth limiting member 233, so that the workpiece 1000 to be detected is located on the rotating tray 231, and the above-mentioned driving motor or the rotating cylinder 232 is restarted to realize the position exchange of the workpiece 1000 to be detected.

Referring to fig. 2 and 5 in combination, the positioning and detecting device 300 includes a rotating disc 310, a positioning mechanism 320 and a detecting mechanism 330.

The rotating disc 310 is provided with a plurality of workpiece accommodating holes 311 with transverse holes 1100, and the workpiece accommodating holes 311 are used for receiving the workpieces 1000 to be detected with uniform position state transported from the material arranging mechanism 230, and the workpieces 1000 to be detected are transported to the subsequent stations along with the rotating disc 310. The positioning mechanism 320 is mounted on the rotating path of the rotating disk 310, and is used for positioning the workpiece 1000 to be inspected. The detecting mechanism 330 is mounted on the rotating path of the rotating disk 310 for detecting the workpiece 1000 to be detected.

In this way, the workpiece 1000 to be detected after being taken out from the Kong Zhengliao finding device 200 can be continuously transported to the positioning mechanism 320 and the detecting mechanism 330 under the action of the rotating disc 310, the workpiece 1000 to be detected can be accurately positioned under the action of the positioning mechanism 320, and the transverse hole 1100 information of the workpiece 1000 to be detected can be finally obtained through the detection of the detecting mechanism 330.

In some embodiments, in order to ensure that the workpiece 1000 to be inspected can be transported to the rotating disc 310 smoothly, a feeding mechanism 340 is further disposed between the guide rail 210 and the rotating disc 310, the feeding mechanism 340 includes a pipe 341 and a feeder 342, the pipe 341 and the feeder 342 are sequentially connected between the guide rail 210 and the rotating disc 310, wherein the feeder 342 is disposed above the rotating disc 310, and the feeder 342 has a feeding hole for accommodating the workpiece 1000 to be inspected, and the feeding hole is vertically disposed, so that the workpiece 1000 to be inspected can flow into the workpiece accommodating hole 311 to be inspected on the rotating disc 310 in a vertical state.

With continued reference to fig. 2 and 7, in the embodiment of the invention, the positioning mechanism 320 includes a preliminary positioning mechanism 321 and a precise positioning mechanism 322, the precise positioning mechanism 322 is disposed behind the preliminary positioning mechanism 321, and the preliminary positioning mechanism 321 includes a second sensor 3211 disposed along a radial direction of the rotating disc 310 and a driving member 3212 capable of acting on the workpiece 1000 to be inspected to rotate the workpiece 1000 to be inspected, and the driving member 3212 drives the workpiece 1000 to be inspected until the second sensor 3211 senses the transverse hole 1100.

Thus, when the workpiece 1000 to be inspected flowing onto the rotating disc 310 is transported to the preliminary positioning mechanism 321 along with the rotation of the rotating disc 310, when the second sensor 3211 does not sense the transverse hole 1100, the driving member 3212 will act to drive the workpiece 1000 to be inspected to further rotate, so as to finally enable the transverse hole 1100 to be sensed by the second sensor 3211, at this time, the workpiece 1000 to be inspected completes the preliminary positioning, at this time, the center line of the transverse hole 1100 approximately coincides with the radial direction of the rotating disc 310, and there may be a slight deviation, and the accurate positioning mechanism 322 is used to eliminate the deviation.

Specifically, referring to fig. 6 in combination, the precise positioning mechanism 322 includes a pair of tapered positioning pins 3221 movably disposed, where the pair of tapered positioning pins 3221 are coincident with the radial direction of the rotating disk 310, and the pair of tapered positioning pins 3221 can be inserted into two ends of the transverse hole 1100, so that the position of the workpiece 1000 to be detected is further aligned.

Thus, by controlling the simultaneous insertion of a pair of tapered pins 3221 into both ends of the transverse bore 1100, the tapered pins 3221 can force the workpiece 1000 to be inspected to further rotate, ultimately causing the direction of the transverse bore 1100 to fully coincide with the direction defined by the pair of tapered pins 3221, such that the workpiece 1000 to be inspected is centered to the final desired precise position.

In some embodiments, the driving member 3212 is a rubber friction wheel, the preliminary positioning mechanism 321 further includes a second driving motor 3213, the rubber friction wheel is connected to the second driving motor 3213, and the second driving motor 3213 drives the driving member 3212 to rotate, so as to drive the workpiece 1000 to be inspected to rotate.
