Description

Technical Field

[0001] The utility model belongs to the technical field of bearing processing, in particular to a surface grinding bracket for a bearing ring. Background Art

[0002] When machining the end face of a bearing ring on a compound double-end grinder, the ring is positioned between two upper and lower brackets. The positions of the upper and lower brackets are adjusted to align the center of the ring with the center of the grinding wheel. During machining, the ring is positioned using its outer diameter and placed between the upper and lower brackets. The feed tray feeds the ring between the two grinding wheels for reciprocating grinding. However, because the brackets have only one support point, located in the center of the ring, the inner ring rib is too narrow, resulting in a small contact area. This makes the ring unstable during the grinding process, leading to uneven grinding of both end faces.

[0003] In the related technology, a search revealed a solution for a surface grinding bracket for a bearing ring (Announcement No. CN220637232U). By improving and optimizing the surface grinding bracket for the bearing ring in the prior art, an adjustment mechanism is designed between the bracket body and the side seat, so that the height of the bracket body can be easily adjusted up and down, so that the operator can adaptively adjust the distance between the two bracket bodies according to bearing rings of different specifications, thereby improving the flexibility of use. The adjustment method of the bracket body when adjusting up and down is simple and quick, and is easy for the operator to operate on site. However, after the bearing ring is fixedly ground by the bracket, it is necessary to pause the grinding work and disassemble the ground bearing ring, and then install the new bearing ring that needs to be ground before continuing to grind the workpiece, resulting in low grinding efficiency of the bearing ring.

[0025] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0026] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0027] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0028] To solve the problem that after the fixed grinding of the bearing ring, the grinding work needs to be stopped to disassemble the grinding bearing ring, and then install the new bearing ring to be ground before continuing to grind the workpiece, which leads to low grinding efficiency of the bearing ring, please refer to Figures 1 to 5 As shown, a surface grinding bracket for a bearing ring, in this embodiment, includes a workbench 1 and a support column 2. The support column 2 is welded to the lower side of the workbench 1. There are four support columns 2, which are respectively welded to the four corners of the lower side of the workbench 1, so that the overall bracket is supported more firmly. A grinding mechanism is connected to the upper side of the workbench 1.

[0029] The grinding mechanism includes a support frame 301, which is fixedly connected to the left end of the upper side of the workbench 1. A hydraulic cylinder 302 is installed on the upper side of the support frame 301, and a first motor 303 is installed at the lower end of the output shaft of the hydraulic cylinder 302. An upper grinding wheel 304 for grinding bearing rings is installed at the lower end of the output shaft of the first motor 303. A second motor 305 is installed at the left end of the lower side of the workbench 1, and a lower grinding wheel 306 for grinding bearing rings is installed at the upper end of the output shaft of the second motor 305. By starting the hydraulic cylinder 302, the height of the first motor 303 and the upper grinding wheel 304 is changed, and the distance between the upper grinding wheel 304 and the lower grinding wheel 306 is changed, so that bearing rings of different lengths can be ground.

[0030] A third motor 401 is installed at the middle position of the lower side of the workbench 1, and a connecting plate 402 is installed on the upper end of the output shaft of the third motor 401. The outer end of the connecting plate 402 is fixedly connected to the inner ring plate 403, and a connecting rod 404 is welded to the outer side of the inner ring plate 403, and the other end of the connecting rod 404 is welded to the outer ring plate 405. The inside of the inner ring plate 403 is connected to a threaded rod 406, and one end of the threaded rod 406 is welded to a rotating handle 407. A plurality of threaded holes of equal arc are opened inside the inner ring plate 403, and the outer side of the threaded rod 406 is threadedly connected to the inner side of the threaded hole, so that the rotating handle 407 is rotated so that the threaded rod 406 is located in the threaded hole. When rotating, the threaded rod 406 can move relative to the inner ring plate 403, so that bearing rings of different sizes can be clamped and fixed between the movable clamping plate 409 and the fixed clamping plate 411.

[0031] A bearing 408 is installed at the other end of the threaded rod 406, and the outer end of the bearing 408 is fixedly connected to a movable splint 409. Limiting rods 410 are welded at both ends of the outer side of the movable splint 409, and a fixed splint 411 is welded on the inner side of the outer ring plate 405. Limiting holes are provided at both ends of the threaded rod 406 inside the inner ring plate 403. The outer side of the limiting rod 410 is slidably connected to the inner side of the limiting hole, so that when the threaded rod 406 moves and drives the movable splint 409 to move, it will drive the limiting rod 410 to slide along the inner side of the limiting hole, so that the movable splint 409 will not rotate while moving.

[0032] The lower side of the upper grinding wheel 304 and the upper side of the lower grinding wheel 306 are respectively slidably connected to the upper and lower sides of the bearing ring clamped between the movable clamping plate 409 and the fixed clamping plate 411, so that starting the first motor 303 and the second motor 305 can rotate the upper grinding wheel 304 and the lower grinding wheel 306 to grind the upper and lower sides of the bearing ring moved therebetween.

[0033] A pad 5 is welded to the upper side of the workbench 1, below the right end of the inner annular plate 403. The top of the pad 5 is at the same height as the top of the lower grinding wheel 306. Therefore, when the bearing ring is installed at the right end of the inner annular plate 403, the top of the pad 5 supports the bottom of the bearing ring, positioning the bearing ring for installation so that the fixed bearing ring can be accurately moved between the upper grinding wheel 304 and the lower grinding wheel 306.

[0034] An upper baffle 6 is welded to the right end of the support frame 301, and a lower baffle 7 is welded to the upper side of the workbench 1 below the upper baffle 6. The lower side of the upper baffle 6 and the upper side of the lower baffle 7 are slidably connected to the upper and lower sides of the connecting plate 402. This allows the upper baffle 6 and the lower baffle 7 to block the grinding debris generated by the upper grinding wheel 304 and the lower grinding wheel 306 without affecting the rotation of the connecting plate 402, thereby protecting the personnel who are disassembling and assembling the bearing ring at the right end.

[0035] The hydraulic cylinder 302, the first motor 303, the second motor 305 and the third motor 401 are all conventional instruments. Their working principles, sizes and models are irrelevant to the problem solved by this application, so they are not described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in this utility model.

[0036] Working principle: When grinding the bearing ring, the surface grinding bracket of the bearing ring first rotates the rotary handle 407 to rotate the threaded rod 406 and drives the movable clamping plate 409 away from the fixed clamping plate 411, and then places the bearing ring to be ground on the pad 5 and between the movable clamping plate 409 and the fixed clamping plate 411, then reverses the rotary handle 407 to rotate the threaded rod 406 and drives the movable clamping plate 409 to move toward the fixed clamping plate 411 until the bearing ring is fixed between the movable clamping plate 409 and the fixed clamping plate 411, and then Start the third motor 401 and rotate its output shaft to drive the connecting plate 402 to rotate, so that the inner annular plate 403 and the outer annular plate 405 rotate, and move the bearing ring closest to the upper grinding wheel 304 and the lower grinding wheel 306 to between the upper grinding wheel 304 and the upper grinding wheel 304, and grind it with the rotating upper grinding wheel 304 and the lower grinding wheel 306. At the same time, the bearing ring that has been polished between the movable clamping plate 409 and the fixed clamping plate 411 on the pad 5 is removed, and then the bearing ring to be polished is installed, and this work process is repeated to continuously polish the bearing ring.
