In some instances, well-known methods and structures have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other.

[0034] Please see Figures 1 to 9 The present invention provides a technical solution:

[0035] Example 1

[0036] The automatic bearing ring inspection machine includes: a fixed side plate 1, a support shaft 9, and a chamfer inspection cylinder 11.

[0037] Specifically, a digital sensor 2 is fixedly connected to one end of the fixed side plate 1, and a digital display screen 101 is provided at the other end of the fixed side plate 1 to display the detection data of this device. The digital sensor 2 is fixed on the mounting frame 3, and a pressure roller 4 is rotatably mounted on the lower end of the mounting frame 3. The pressure roller 4 is driven by an external vertical cylinder to slide up and down in the vertical direction. The pressure roller 4 is located directly above the workpiece 5 to be tested and presses the workpiece 5 firmly. The digital sensor 2 is used to perform groove swing detection on the workpiece 5 to be tested. A fixed plate 6 and a clamping slide plate 7 are respectively provided on both sides of the workpiece 5 to be tested. The fixed plate 6 and the clamping slide plate 7 are respectively attached to the two end faces of the workpiece 5 to prevent the workpiece 5 to be tested from shifting laterally during the detection process. When the workpiece 5 to be tested rotates, the pressure roller 4 presses on the upper surface of the workpiece 5 to be tested. If the roundness of the workpiece 5 to be tested is not standard, the pressure roller 4 will jump up and down. At this time, by observing the change in the extension and retraction of the digital sensor 2 through the external main controller, the amplitude of the vertical jump of the pressure roller 4 can be determined, and thus the roundness of the workpiece 5 to be tested can be detected. In addition, the fixed plate 6 is fixed itself, and the clamping slide plate 7 can slide to approach or move away from the fixed plate 6. When the workpiece 5 to be tested rotates, the groove of the workpiece 5 to be tested can also be automatically detected by detecting the sliding amount of the clamping slide plate 7. The surfaces of the fixed plate 6 and the clamping slide plate 7 are both fixedly installed with end face detection sensors 8 for detecting the end face of the workpiece 5 to be tested. The end face detection sensors 8 are directly facing the edge of the end face of the workpiece 5 to be tested. When the workpiece 5 to be tested rotates, they are used to perform accuracy detection at various positions of the end face of the workpiece 5 to be tested.

[0038] Secondly, there are two support shafts 9, which are located on both sides below the workpiece 5 and support it. The pressure roller 4 and the two support shafts 9 can define a circle, which is the workpiece 5. Therefore, the workpiece 5 can be positioned and can only rotate, but will not move back and forth. The two ends of the support shaft 9 are movably connected to the fixed plate 6 and the clamping slide plate 7, respectively, without affecting the lateral sliding of the clamping slide plate 7 (i.e., its proximity or distance from the fixed plate 6). The support shaft 9 is driven to rotate by the drive motor 10 fixed to the surface of the fixed plate 6. The drive motor 10 can drive one support shaft 9 to rotate. The support shaft 9 drives the workpiece 5 to rotate through the friction between itself and the workpiece 5, thereby ensuring that the device can perform dynamic detection of the workpiece 5.

[0039] In addition, the chamfer detection cylinder 11 is fixed to the surface of the clamping slide plate 7. One end of the chamfer detection cylinder 11 is fixedly connected to the chamfer detector 12 by bolts. The upper and lower end faces of the chamfer detector 12 are set as symmetrical inclined structures. The chamfer detector 12 corresponds to the opening end of the inner cavity of the workpiece 5 to be tested. Figure 7 As shown, the chamfer detection cylinder 11 extends and retracts during operation to drive the chamfer detector 12 to approach or move away from the workpiece 5 to be tested. When the chamfer detector 12 approaches the workpiece 5 to be tested, the two end faces of the chamfer detector 12 are respectively in contact with the chamfers at the upper and lower ends of the edge of the workpiece 5 to be tested. By observing the extension and retraction of the chamfer detection cylinder 11, the opening depth of the chamfer on the edge of the workpiece 5 to be tested can be detected. The extension and retraction of the chamfer detection cylinder 11 can be electrically connected and detected by an external main controller, thereby realizing automated detection.

[0040] Example 2

[0041] Based on Embodiment 1, in order to convey the workpiece 5 to be tested directly below the pressure roller 4, this application also has a feed trough plate 16 fixedly connected to one side of the fixed side plate 1 for conveying the workpiece 5 to be tested directly below the pressure roller 4. A strip-shaped agitator plate 13 is provided above the inner cavity of the feed trough plate 16. A fixed shaft 17 fixedly connected to the fixed side plate 1 is movably inserted into the middle of the strip-shaped agitator plate 13. The upper half of the strip-shaped agitator plate 13 is twisted by 60 degrees. The strip-shaped agitator plate 13 can rotate around the fixed shaft 17. When the workpiece 5 to be tested rolls in the inner cavity of the feed trough plate 16, it can push the strip-shaped agitator plate 13 to rotate.

[0042] Example 3

[0043] Based on Embodiment 2, in order to automatically count the workpiece 5 to be tested, this application further includes a mounting plate 18 fixedly connected to a fixed side plate 1 on one side of the upper half of the strip-shaped actuating plate 13. The surface of the mounting plate 18 has an arc-shaped adjustment slot 19, and a counter 20 is disposed through the inner cavity of the arc-shaped adjustment slot 19. One end of the counter 20 corresponds directly to the upper half of the strip-shaped actuating plate 13, and two nuts are disposed in the middle of the counter 20, with the two nuts clamping and fixing the two sides of the mounting plate 18 respectively. Figure 5 As shown, the counter 20 can be fixed to the surface of the mounting plate 18 by a nut, and its position is adjustable. When the bar-shaped actuating plate 13 rotates, its upper half can tilt and press the end of the counter 20 to perform a count. A torsion spring is also provided between the fixed shaft 17 and the bar-shaped actuating plate 13 to reset the bar-shaped actuating plate 13. That is to say, after each workpiece 5 to be tested rolls in the inner cavity of the feed trough plate 16 and passes the lower end of the bar-shaped actuating plate 13, the counter 20 can perform a count, thereby realizing automatic counting of the workpiece 5 to be tested.

[0044] Example 4

[0045] Based on Embodiment 3, in order to clamp the workpiece 5 to be tested, this application further includes a material distribution trough plate 14 provided at one end of the fixed plate 6. A rotating shaft 24 is fixedly connected to the bottom of one end of the material distribution trough plate 14. The rotating shaft 24 is rotatably connected to the worktable of this device. A reset torsion spring 25 is sleeved on the outside of the rotating shaft 24. Therefore, the material distribution trough plate 14 can rotate and can be reset by the reset torsion spring 25. A push cylinder 141 is provided on one side of the material distribution trough plate 14 and is fixedly connected to the worktable of this device. One end of the push cylinder 141 abuts against the side of the material distribution trough plate 14. A pressing plate 23 is fixedly connected to one end of the material distribution trough plate 14. The pressing plate 23 abuts against the side of the clamping slide plate 7. When the push cylinder 141 extends, it pushes the material distribution trough plate 14 to rotate around the rotating shaft 24. At this time, the pressing plate 23 presses the side of the clamping slide plate 7, causing the clamping slide plate 7 to move closer to the fixed plate 6, thereby clamping the workpiece 5 to be tested.

[0046] Example 5

[0047] Based on Embodiment 4, in order to guide and reset the sliding of the clamping slide plate 7, this application further includes a limiting slider 26 fixedly connected to the lower surface of the clamping slide plate 7. The limiting slider 26 is slidably connected to the worktable of this device. A reset spring 27 is fixedly connected to the side of the limiting slider 26. The limiting slider 26 is used to guide the sliding of the clamping slide plate 7, and the reset spring 27 is used to reset the clamping slide plate 7. When the material distribution plate 14 rotates in the reverse direction to separate the extrusion plate 23 from the clamping slide plate 7, the thrust provided by the reset spring 27 ensures that the limiting slider 26 can slide in the reverse direction and drive the clamping slide plate 7 to separate from the fixed plate 6, so that the next workpiece 5 to be tested can enter between the fixed plate 6 and the clamping slide plate 7.

[0048] Example 6

[0049] Based on Embodiment 5, in order to separate defective products, this application further includes a discharge trough plate 15 provided at the other end of the distribution trough plate 14. A distribution port 28 is provided on the side of the discharge trough plate 15 and corresponds to the distribution trough plate 14. Two partitions 29, fixed to the inner cavity of the discharge trough plate 15, are provided at the inner opening end of the distribution port 28. Each partition 29 divides the distribution port 28 into two symmetrical small spaces. A defective product discharge hole 30 is opened at the bottom of the discharge trough plate 15, located between the two partitions 29. Figure 1 and 8 As shown, the workpiece 5 to be tested directly below the pressure roller 4 rolls away from between the fixed plate 6 and the clamping slide plate 7, and is guided by the material distribution trough plate 14 to enter the inner cavity of the material distribution port 28. If the workpiece 5 to be tested is a defective product, the end of the material distribution trough plate 14 corresponds to the space between the two partitions 29, and the defective product is sent into the space between the two partitions 29 and falls into the defective product frame below through the defective product drop hole 30. If the workpiece 5 to be tested is a qualified product, the end of the material distribution trough plate 14 corresponds to one side of a partition 29, and the qualified product is sent into the middle of the discharge trough plate 15.

[0050] Example 7

[0051] Based on Embodiment Six, in order to lubricate qualified products, this application also has an oil return hole 31 provided on one side of a partition 29, which is opened at the bottom of the discharge trough plate 15. Above the oil return hole 31, a lubrication nozzle 32 is fixedly connected to the side of the discharge trough plate 15. The lubrication nozzle 32 is connected to an external oil pump through an oil pipe. When a qualified product enters the inner cavity of the discharge trough plate 15 and does not fall from the inner cavity of the defective product drop hole 30, the lubrication nozzle 32 draws lubricating oil through the oil pipe and sprays it on the surface of the qualified product to lubricate the product. Excess lubricating oil can be recycled and reused through the oil return hole 31.

[0052] Example 8

[0053] Based on Embodiment 7, in order to push away qualified products, this application further includes a discharge cylinder 33 fixedly connected to one end of the discharge trough plate 15, a push plate 34 fixedly connected to one end of the discharge cylinder 33, a circular hole corresponding to and adapted to the push plate 34 in the middle of the partition plate 29, and the other end of the discharge trough plate 15 is set as a discharge port and the push plate 34 is driven by the discharge cylinder 33 to slide and push the material to move. When the discharge cylinder 33 is working, it extends and retracts to drive the push plate 34 to move and pass through the circular hole in the middle of the partition plate 29, so as to push the qualified products at the bottom of the discharge trough plate 15 until the qualified products are pushed out from the end of the workpiece 5 to be tested and collected in the qualified product material frame.

[0054] Example 9

[0055] Based on Embodiment 8, in order to push away the workpiece 5 to be tested between the fixing plate 6 and the clamping slide plate 7, this application further includes a through hole in the middle of the bottom of the feed trough plate 16, in which a matching pusher block 21 is slidably disposed, and the upper surface of the pusher block 21 is inclined. The pusher block 21 is driven to slide by a pusher cylinder 22, and the pusher cylinder 22 is fixedly connected to the worktable of this device. Figure 6 and Figure 1 As shown, when the pusher cylinder 22 extends during operation, it can drive the pusher block 21 to slide. The pusher block 21 can move between the fixed plate 6 and the clamping slide plate 7 and push the workpiece 5 to be tested away. When the pusher cylinder 22 retracts, the pusher block 21 slides in the opposite direction and is stored in the through hole at the bottom of the feed trough plate 16. The upper surface of the pusher block 21 is flush with the bottom of the feed trough plate 16, so as to avoid obstructing the workpiece 5 to be tested rolling inside the feed trough plate 16.

[0056] Example 10

[0057] Based on Embodiment Nine, in order to move the strip-shaped actuating plate 13, the feed trough plate 16 of this application is inclined downward to facilitate the conveying and rolling of the workpiece 5 to be tested. The lower end of the strip-shaped actuating plate 13 is located in the inner cavity of the feed trough plate 16 and a gap is left between it and the bottom of the feed trough plate 16. The lower end of the strip-shaped actuating plate 13 is bent upward to form a "J" shape, such as... Figure 6 As shown, when the workpiece 5 to be tested touches the lower end of the strip actuation plate 13, it can smoothly actuate the strip actuation plate 13 to rotate, and ensure that the workpiece 5 to be tested passes the lower end of the strip actuation plate 13.
