[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] A positioning fixture for end face treatment of bearing rings, the structure of which can be made of Figures 1-6 The following is an illustration. In this embodiment, the positioning fixture for the end face treatment of bearing rings includes: a support platform 1, a material cylinder 2, a positioning component, and a pusher plate 5. The support platform 1 is used to provide processing space for the end face treatment of the workpiece 8 to be processed. The material cylinder 2 is used to stack and store multiple workpieces 8 to be processed in the same batch. The cooperation between the pusher plate 5 and the positioning component is used to position and clamp the workpiece 8 to be processed in order to facilitate subsequent end face treatment.

[0032] Specifically, the top surface of the support platform 1 is provided with a mounting hole 11, and a rotatable support plate 6 is provided inside the mounting hole 11. The material cylinder 2 is detachably mounted on the top surface of the support platform 1. The top end of the material cylinder 2 is provided with a feeding port 21, and the bottom end of the material cylinder 2 is provided with a discharge port. A pushing channel is formed between the bottom end of the material cylinder 2 and the top surface of the support platform 1. The positioning assembly includes a mounting strip 3 and a positioning strip 4. The mounting strip 3 is mounted on the top surface of the support platform 1, and the mounting strip 3 and the material cylinder 2 are located on opposite sides of the mounting hole 11. The positioning strip 4 is adjustablely positioned on the side of the mounting strip 3 near the mounting hole 11, and a rotatable positioning roller 41 is provided on the side wall of the positioning strip 4 near the mounting hole 11. The pusher plate 5 is slidably mounted inside the pushing channel. A V-shaped cut 51 is provided on the side wall of the pusher plate 5 near the mounting hole 11, and a pusher roller 52 is provided on the inner side wall of the V-shaped cut 51.

[0033] Before use, the operator can place the grinding equipment (such as a grinder with a rotating grinding disc) above the support plate 6 and stack the workpieces 8 to be processed in the same batch inside the material cylinder 2. During use, the operator can first slide the pusher plate 5 away from the mounting hole 11, so that the V-shaped cut 51 moves below the outlet of the material cylinder 2, facilitating the entry of the lowest workpiece 8 into the V-shaped cut 51. Next, the pusher plate 5 can be slid closer to the mounting hole 11, so that the workpiece 8 inside the V-shaped cut 51 moves onto the support plate 6. When the workpiece 8 contacts the positioning roller 41 in the positioning assembly, the workpiece 8 is clamped and fixed by the pusher plate 5 and the positioning assembly. The operator can pre-adjust the position of the positioning strip 4 according to the diameter of the workpiece 8, so that the workpiece 8 remains concentrically positioned with the support plate 6 after clamping and fixing, thereby reducing the difficulty of positioning and alignment. Once clamping is complete, the operator can drive the grinding equipment to contact the top end face of the workpiece 8 to be processed, thereby polishing it. Furthermore, during the processing, since the support plate 6 can rotate, and the pusher plate 5 and positioning strip 4 are respectively equipped with pusher rollers 52 and positioning rollers 41, the operator can also rotate the clamped workpiece 8 by rotating the support plate 6, thereby improving the end face processing effect.

[0034] Optionally, to achieve a rotatable connection between the bearing plate 6 and the bearing platform 1, such as... Figure 3 As shown, a support frame 12 can be provided inside the mounting hole 11, and a connecting hole 121 is provided on the support frame 12. Correspondingly, a connecting shaft is provided on the bottom surface of the support plate 6, and the connecting shaft can be rotatably inserted into the connecting hole 121 so that the support plate 6 can rotate during use.

[0035] In addition, to reduce the difficulty of rotating the bearing plate 6, such as Figure 4 As shown, the top surface of the support plate 6 is provided with a groove for receiving an annular ring. An operating ring 62 is located inside the groove. The top surface of the operating ring 62 should be flush with the top surface of the support plate 6, and multiple anti-slip grooves are provided on the top surface of the operating ring 62. When it is necessary to rotate the support plate 6, the operator can apply torque to the area where the operating ring 62 is located. Due to the anti-slip grooves on the operating ring 62, slippage between the operator's hand and the operating ring 62 can be avoided, thus facilitating accurate and convenient rotation of the support plate 6.

[0036] After the top end face of the workpiece 8 is processed, the operator can first slide the pusher plate 5 slightly away from the mounting hole 11 to flip the workpiece 8, and then slide the pusher plate 5 back towards the mounting hole 11 to clamp the workpiece 8 again for processing its bottom end face. Similarly, after processing the end face of one workpiece 8, the operator can move the V-shaped cutter 51 back below the material cylinder 2 to process subsequent workpieces 8.

[0037] It should be noted that the operator should adjust the distance between the material cylinder 2 and the support platform 1 according to the thickness of the workpiece to be processed, and ensure that the end of the pusher plate 5 away from the V-shaped cut 51 always stays below the material cylinder 2 during the operation, so as to ensure that the device can push only one workpiece 8 to be processed from the material cylinder 2 onto the support plate 6 each time.

[0038] Optionally, to achieve a detachable connection between the material cylinder 2 and the support platform 1, the bottom end of the material cylinder 2 may be provided with an assembly ring 22, and an assembly hole 221 may be provided on the assembly ring 22. A positioning post 14 may be provided on the bottom surface of the support platform 1, and a connecting screw 15 with a diameter smaller than the positioning post 14 may be provided on the top surface of the positioning post 14. During assembly, the operator can insert the connecting screw 15 into the assembly hole 221 and install a limiting nut 151 on the connecting screw 15, thereby limiting the material cylinder 2 above the assembly ring 22 with the help of the limiting nut 151.

[0039] As an example and not a limitation, the operator may also set gaskets of different thicknesses or numbers between the top end face of the assembly ring 22 and the positioning post 14 according to the actual thickness of the workpiece 8 to be processed, so as to control the distance between the bottom end of the material cylinder 2 and the support platform 1.

[0040] As an optional implementation of this embodiment, to improve the automation level of the pusher plate 5, a drive cylinder 53 can be provided on the support platform 1, and the extension rod of the drive cylinder 53 should be connected to the side wall of the pusher plate 5 away from the V-shaped cut 51. Before use, the operator can adjust the position of the positioning strip 4 according to the diameter specification of the workpiece 8 to be processed, and set the extension rod stroke of the drive cylinder 53 accordingly, so as to automatically drive the pusher plate 5 to slide with the help of the drive cylinder 53, reducing the labor intensity of the operator.

[0041] like Figure 1 and Figure 6 As shown, to facilitate adjustment of the position of the positioning strip 4, a guide rod 42 may be provided on the side wall of the positioning strip 4 away from the positioning roller 41. The mounting strip 3 may be provided with a guide hole 31 and an adjusting screw hole 32 for accommodating the guide rod 42. An adjusting screw 321 parallel to the guide rod 42 should be provided inside the adjusting screw hole 32. After assembly, the end of the adjusting screw 321 will abut against the positioning strip 4. The operator can adjust the position of the end of the adjusting screw 321 by rotating it, thereby restricting the positioning strip 4 to a suitable position.

[0042] In addition, to improve the positioning support effect of the positioning component on the workpiece 8 to be processed, this embodiment may provide two positioning rollers 41 on the positioning strip 4, and a positioning gap should be formed between the two positioning rollers 41, thereby improving the contact reliability between the workpiece 8 to be processed and the positioning component.

[0043] In actual operation, the end face treatment of bearing rings generates a certain amount of debris. To facilitate debris collection, this embodiment provides multiple slag discharge slits 61 on the support plate 6 and a detachable slag collection drawer 7 on the bottom surface of the support platform 1, with the drawer 7 located directly below the mounting hole 11. When debris is generated during the processing, it can enter the slag collection drawer 7 along the slag discharge slits 61. Workers can periodically clean the drawer 7, thereby reducing the difficulty of debris collection and processing.

[0044] In addition, in order to achieve a detachable connection between the slag collection drawer 7 and the support platform 2, a limiting strip 71 can be provided on the top surface of the slag collection drawer 7, and a limiting groove 13 for accommodating the limiting strip 71 can be provided on the bottom surface of the support platform 1, so that the slag collection drawer 7 and the support platform 2 can be disassembled and assembled by means of the cooperation between the limiting strip 71 and the limiting groove 13.

[0045] The effects of the above solution are explained below:

[0046] This embodiment provides a positioning fixture for end face treatment of bearing rings. It can push workpieces stored in a cylinder one by one onto a support plate via the sliding of a pusher plate, and can clamp and position the workpieces using the pusher plate and positioning assembly, thereby improving the efficiency of bearing ring end face treatment. Secondly, this device can adjust the position of the positioning strip according to the diameter specifications of the workpiece, thus having better adaptability. Furthermore, this device can also drive the support plate to rotate during processing, thereby improving the end face treatment effect of the bearing rings.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
