Description

Technical Field

[0001] This utility model relates to the field of bearing manufacturing equipment technology, and in particular to a support device for processing cages. Background Technology

[0002] The cage support device ensures that the bearing cage can be stably fixed in the working position during the grinding process, and facilitates the adjustment of the grinding angle and force to achieve the expected grinding effect, thereby ensuring the accuracy and consistency of the grinding operation. For large-volume bearing cages, it is necessary to grind and polish the inner wall and edges of the rolling element mounting opening of the cage, which requires frequent adjustment of the grinding and polishing position or the bearing cage orientation.

[0003] Traditional cage machining processes typically use fixed clamping devices as support mechanisms. When clamping the cage, it is impossible to control the cage's rotation. When adjusting the cage angle, it is necessary to loosen the clamping mechanism in the support device and then control the clamping mechanism to clamp the cage again after adjustment. This makes cage angle adjustment difficult and is not conducive to efficient cage machining. Utility Model Content

[0004] This disclosure relates to a support device for processing cages, which solves the problem that traditional support devices used in cage processing are generally fixed clamping devices. When clamping the cage, the rotation of the cage cannot be controlled. When adjusting the angle of the cage, it is necessary to loosen the clamping mechanism in the support device and then control the clamping mechanism to clamp the cage again after the adjustment is completed. This makes the angle adjustment of the cage difficult and is not conducive to the efficient processing of the cage.

[0005] In a first aspect, this disclosure provides a support device for processing a cage, specifically comprising: a cage support platform; two external limiting shafts rotatably connected to the upper part of the cage support platform via bearings; a servo motor fixedly connected to the lower surface of the cage support platform via bolts; the shaft of the servo motor fixedly connected to the lower end of the support shaft of the right-side external limiting shaft; a support platform guide opening in the middle of the front edge of the cage support platform; an inner limiting pull block slidably connected inside the support platform guide opening; a spiral push cylinder fixedly connected to the lower surface of the cage support platform via bolts; the push rod of the spiral push cylinder facing forward and perpendicular to the front surface of the cage support platform; the front end of the push rod of the spiral push cylinder fixedly connected to the inner limiting pull block; a locking plate guide frame fixedly connected to the upper surface of the cage support platform; a telescopic push plate slidably connected inside the locking plate guide frame; and an electromagnet fixedly connected to the rear edge of the upper surface of the cage support platform, the electromagnet being located behind the telescopic push plate.

[0006] In at least some embodiments, two inner protrusions are fixedly connected to the inner side walls of the support platform guide.

[0007] In at least some embodiments, a limiting outer edge is machined protruding above and below the outer limiting pivot.

[0008] In at least some embodiments, the upper surface of the inner limit block is rotatably connected to an inner limit shaft via a bearing, and the inner limit shaft is perpendicular to the upper surface of the inner limit block.

[0009] In at least some embodiments, the side of the inner limiting block is provided with a side guide groove, and the side guide groove is slidably connected to the inner protrusion of the guide opening.

[0010] In at least some embodiments, a locking block is fixedly connected to the front edge of the upper surface of the telescopic push plate, the front end of the locking block has a wedge-shaped structure, and a reset tension spring is fixedly connected to the rear surface of the locking block.

[0011] In at least some embodiments, the rear end of the reset spring is fixedly connected to the rear end of the lock plate guide frame, and a magnetic plate is fixedly connected to the rear edge of the upper surface of the telescopic push plate.

[0012] This utility model provides a support device for processing cages, which has the following beneficial effects:

[0013] The bearing cage support device of this utility model is equipped with a bearing clamping mechanism. Two outer limiting shafts are attached to the outer surface of the cage to form a rolling connection, and an inner limiting shaft is attached to the inner surface of the cage to form a rolling connection. This can lock the position of the bearing cage and prevent it from shaking during processing. At the same time, a servo motor drives the outer limiting shaft to rotate. The outer limiting shaft forms a rolling connection with the bearing cage, which can drive the bearing cage to rotate circumferentially and adjust the orientation of the bearing cage so that different directions of the bearing cage face the grinding and polishing equipment, realizing multi-directional processing of the bearing cage.

[0014] In addition, a cage orientation mechanism consisting of an electromagnet and a telescopic push plate is provided. Under normal conditions, during the processing of the bearing cage, the telescopic push plate moves forward under the action of the return spring, causing the insert plate locking block to enter the rolling element mounting port of the cage, thereby locking the cage circumferentially and preventing the cage from shaking during processing. When it is necessary to adjust the cage orientation, the electromagnet is energized, and the magnetic plate is pulled backward by the magnetic attraction force, causing the insert plate locking block to disengage from the rolling element mounting port of the cage. This allows the cage to rotate under the drive of the servo motor, adjusting its orientation for multi-directional processing. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1: Please refer to Figures 1 to 6 :

[0028] This utility model proposes a support device for processing a cage, comprising: a cage support platform 1, two outer limiting shafts 2 rotatably connected to the upper part of the cage support platform 1 via bearings, a servo motor 3 fixedly connected to the lower surface of the cage support platform 1 via bolts, the shaft of the servo motor 3 fixedly connected to the lower end of the support shaft of the outer limiting shaft 2 located on the right side, a support platform guide opening 101 opened in the middle of the front edge of the cage support platform 1, an inner limiting pull block 4 slidably connected inside the support platform guide opening 101, a spiral push cylinder 5 fixedly connected to the lower surface of the cage support platform 1 via bolts, the push rod of the spiral push cylinder 5 facing forward and perpendicular to the front surface of the cage support platform 1, the front end of the push rod of the spiral push cylinder 5 fixedly connected to the inner limiting pull block 4, a locking plate guide frame 6 fixedly connected to the upper surface of the cage support platform 1, a telescopic push plate 7 slidably connected inside the locking plate guide frame 6, and an electromagnet 8 fixedly connected to the rear edge of the upper surface of the cage support platform 1, the electromagnet 8 being located behind the telescopic push plate 7.

[0029] In this embodiment, two inner protrusions 102 are fixedly connected to the inner side walls of the support platform guide 101. An inner limiting shaft 401 is rotatably connected to the upper surface of the inner limiting block 4 via a bearing. The inner limiting shaft 401 is perpendicular to the upper surface of the inner limiting block 4. A side guide groove 402 is provided on the side of the inner limiting block 4, and the side guide groove 402 is slidably connected to the inner protrusions 102. The position of the inner limiting block 4 can be adjusted by the action of the spiral push cylinder 5 during circumferential movement. When supporting the cage, the inner limit block 4 is pushed forward a certain distance by the spiral push cylinder 5, placing the cage between the two outer limit rotating shafts 2 and the inner limit rotating shaft 401. The spiral push cylinder 5 is then controlled to retract, pulling the inner limit block 4 backward, so that the two outer limit rotating shafts 2 are in contact with the outer surface of the cage and form a rolling connection, and the inner limit rotating shaft 401 is in contact with the inner surface of the cage and forms a rolling connection, thereby locking the position of the bearing cage and preventing the bearing cage from shaking during processing.

[0030] In this embodiment, a limiting outer edge 201 is protruded above and below the outer limiting shaft 2; the limiting outer edge 201 is used to limit the cage and prevent the bearing cage from shaking or shifting vertically.

[0031] In this embodiment, a locking block 701 is fixedly connected to the front edge of the upper surface of the telescopic push plate 7. The front end of the locking block 701 has a wedge-shaped structure, and a return spring 702 is fixedly connected to the rear surface of the locking block 701. The rear end of the return spring 702 is fixedly connected to the rear end of the locking plate guide frame 6, and a magnetic plate 703 is fixedly connected to the rear edge of the upper surface of the telescopic push plate 7. Under normal conditions, the telescopic push plate 7 moves forward under the action of the return spring 702, causing the locking block 701 to enter the rolling element mounting port of the cage, thereby circumferentially moving the cage. The locking mechanism prevents the cage from vibrating during processing. When the cage orientation needs to be adjusted, the electromagnet 8 is energized, and the magnetic attraction plate 703 is pulled backward by the magnetic attraction force, so that the insert plate locking block 701 disengages from the rolling element mounting port of the cage. This allows the cage to rotate under the drive of the servo motor 3, and the orientation can be adjusted for multi-directional processing. After the adjustment is completed, the servo motor 3 is stopped, and the electromagnet 8 is de-energized. The telescopic push plate 7 moves forward again under the action of the reset spring 702 and inserts into the rolling element mounting port of the cage.

[0032] In Example 2, based on Example 1, the servo motor 3 and the electromagnet 8 are connected in series. When the servo motor 3 is energized to rotate, the electromagnet 8 is simultaneously energized to pull the telescopic push plate 7 backward, thus achieving linkage and improving the control convenience of the support device.

[0033] The working principle of this embodiment is as follows: First, the spiral push cylinder 5 is extended, pushing the inner limit block 4 forward a certain distance to place the cage between the two outer limit shafts 2 and the inner limit shaft 401. Then, the spiral push cylinder 5 is retracted, pulling the inner limit block 4 backward so that the two outer limit shafts 2 and the outer surface of the cage are in contact and form a rolling connection, and the inner limit shaft 401 and the inner surface of the cage are in contact and form a rolling connection, thereby locking the position of the bearing cage and preventing the bearing cage from shaking during processing. The telescopic push plate 7 moves forward under the action of the return spring 702, causing the insert locking block 701 to enter the rolling element mounting port of the cage. The cage is circumferentially locked to prevent it from vibrating during processing. When changing the orientation of the cage, the electromagnet 8 is energized, and the magnetic attraction plate 703 is pulled backward by the magnetic attraction force, so that the insert locking block 701 disengages from the rolling element mounting port of the cage. The outer limit shaft 2 is rotated by the servo motor 3. The outer limit shaft 2 is driven to rotate circumferentially through the rolling connection between the outer limit shaft 2 and the cage, so that the orientation of the bearing cage is adjusted. After the adjustment is completed, the servo motor 3 is stopped and the electromagnet 8 is de-energized, so that the telescopic push plate 7 moves forward again under the action of the reset spring 702 and inserts into the rolling element mounting port of the cage, thus restoring the lock on the cage.
