It has the characteristics of high load-bearing capacity, impact resistance, high temperature resistance, strong self-lubricating ability, etc. It is particularly suitable for heavy loads, low speeds, reciprocating or swinging, and other occasions where it is difficult to lubricate and form an oil film. It is not afraid of water flushing and other acid erosion and scouring.

[0003] At present, when chamfering an oil-free bearing, it is generally necessary to chamfer both ends of the bearing. When using the existing chamfering devices, most of them require that after one end of the clamped oil-free bearing is chamfered, the clamped oil-free bearing must be manually released, and the chamfering position of the oil-free bearing must be adjusted to clamp it again before the other end of the oil-free bearing can be chamfered again. This makes the chamfering process of both ends of the oil-free bearing more cumbersome and inconvenient, reducing the efficiency of chamfering the oil-free bearing.

[0004] Therefore, it is necessary to provide an oil-free bearing chamfering device to solve the above technical problems. Utility Model Content

Through the setting of the rubber block 12, the friction between the bearing and the clamping plate 7 can be increased, and the stability of the bearing after being clamped can be improved. A slot 8 is provided on the disc 4, and a connecting plate 9 is slidably connected inside the slot 8. A spring 10 is provided on one side of the connecting plate 9, and a touch switch 11 is provided inside the slot 8. An adjustment component and two chamfering components are provided on the workbench 1. Through the coordinated use of structures such as the workbench 1, the arc rack 2, the disc 4, the clamping plate 7, the touch switch 11, the rubber block 12, the drive motor 13, the intercepting rod 15, the bidirectional screw 20 and the turning tool 25, the clamping fixation of the oil-free bearing can be automatically released after the two ends of the oil-free bearing are chamfered and rotated ninety degrees, without the need for workers to manually release the clamping of the oil-free bearing, which is convenient and quick.

[0030] A driving motor 13 is fixedly connected to the bottom of the workbench 1, and an output end of the driving motor 13 is fixedly connected to the bottom of the placement disk 3. A U-shaped plate 14 is fixedly connected to the top of the workbench 1. An intercepting rod 15 is rotatably connected inside the U-shaped plate 14. A spring 2 16 is provided on one side of the intercepting rod 15. The elastic force of the spring 2 16 is greater than the restoring force of the spring 10 after being stretched, and the elastic force of the spring 2 16 is less than the friction force of the rotation of the disk 4 itself, so that after the connecting rod abuts against the intercepting rod 15, under the action of the intercepting rod 15, the connecting plate 9 can slide inside the slot 8, and after the connecting plate 9 abuts against the touch switch 11, the intercepting rod 15 is rotated, and under the action of the driving motor 13, the disk 4 drives the connecting rod to rotate. A control panel 17 is provided on the top of the workbench 1.

[0031] The adjusting component includes a slide groove 19 opened on the top of the workbench 1, and a bidirectional screw rod 20 is rotatably connected inside the slide groove 19. Two sliders 21 are threadedly connected to the bidirectional screw rod 20, and the two sliders 21 are both slidably connected inside the slide groove 19. A driving motor 22 is fixedly installed on one side of the workbench 1, and the output end of the driving motor 22 is fixedly connected to one end of the bidirectional screw rod 20. Through the setting of the adjusting component, the positions of the two turning tools 25 can be adjusted at the same time, so that under the driving action of the two driving motors 3 23, after the two turning tools 25 are rotated, one end of the two oil-free bearings can be chamfered at the same time, thereby improving the chamfering efficiency.

[0032] The chamfering assembly includes a driving motor 3 23 , which is fixedly mounted on the slider 21 , and an annular plate 24 is fixedly connected to the output end of the driving motor 3 23 , and a turning tool 25 is fixedly connected to the annular plate 24 .

[0033] Working principle: during operation, the oil-free bearing to be chamfered is placed between the two clamping plates 7, and then the driving motor 13 is started through the control panel 17, so that it drives the placing plate, the disc 4, the two-way electric telescopic rod 6, the clamping plate 7, the rubber block 12, the spring 10 and the connecting plate 9 to rotate, so that one of the connecting plates 9 abutting against the intercepting rod 15 continuously pushes the intercepting rod 15 to rotate, and squeezes the spring 2 16. After the intercepting rod 15 rotates and no longer abuts against one of the connecting plates 9, under the elastic force of the spring 10, the connecting plate 9 is reset and no longer abuts against the corresponding touch switch 11, so that the two-way telescopic end of the corresponding two-way electric telescopic rod 6 is contracted, driving the two corresponding clamping plates 7 and the two rubber blocks 12 to move on the opposite side, clamping the oil-free bearing to be chamfered, and releasing the intercepting rod 15 abutting against the connecting plate 9, it will be reset under the elastic force of the spring 2 16;

[0034] When the clamped bearing on the disc 4 moves ninety degrees and is located on one side of one of the chamfering components, the connecting plate 9 on the other disc 4 behind the disc 4 slides in the slot 8 under the action of the intercepting rod 15 and abuts against the corresponding touch switch 11, which transmits the signal to the control panel 17, so that the bidirectional telescopic end of the corresponding bidirectional electric telescopic rod 6 is extended, and the corresponding two clamping plates 7 and two rubber blocks 12 are moved to the separated side, and the driving motor 1 13 is stopped at the same time, so that the rotating placement disc 3 stops moving, and the driving motor 2 22 can be started through the control panel 17 to drive the bidirectional screw 20 to rotate, so that the two sliders 21 drive the two driving motors 3 23, the two annular plates 24 and the two turning tools 25 to move to the opposite or separated side along the axial direction of the bidirectional screw 20, so as to adjust the position of the two turning tools 25;

[0035] After the positions of the two turning tools 25 are adjusted, the driving motor three 23 can be started to drive the annular plate 24 and the turning tool 25 to rotate, and the rotating turning tool 25 chamfers one end of the oil-free bearing. After the chamfering of one end of the bearing is completed, the driving motor one 13 can be started again to drive the plurality of discs 4 and the bearing to rotate. During the rotation process, the gear 5 is meshed with the arc rack 2. Under the action of the arc rack 2, the meshing gear 5 drives the disc 4 to rotate half a circle, so that when the bearing with one end chamfered on the disc 4 rotates to the side of the other chamfering component, the end that has not been chamfered faces the chamfering component. At this time, the other end of the oil-free bearing can be chamfered, and after both ends of the bearing are chamfered, it is rotated ninety degrees. When its connecting rod is under the action of the intercepting rod 15, it touches the contact switch 11 again, and then the corresponding two rubber blocks 12 can be separated, and the processed bearing is released to fall into the placement frame 18.

[0036] 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, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or 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.
