[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0034] Reference Figure 1The utility model provides an embodiment: a grinding device for bearing processing, including a workbench 1, which is the base of the bearing processing grinding device and can be placed on the ground for processing operations. It is a prior art. The top outer wall of the workbench 1 is fixedly connected with a cylinder 5, and the top outer wall of the cylinder 5 is fixedly connected with a connecting seat 6. The cylinder 5 is a prior art and can drive the connecting seat 6 to move up and down to move the grinding disc 8 to contact the bearing surface for grinding.
[0035] Reference Figure 1 The top outer wall of the connecting seat 6 is fixedly connected with a motor 7, and the output shaft of the motor 7 is fixedly connected with a grinding disc 8. The motor 7 is a prior art. The motor 7 can drive the grinding disc 8 to rotate to grind the bearing surface. The outer wall of the connecting seat 6 is provided with a shielding mechanism 4. Through the shielding mechanism 4, the waste chips generated during the grinding process can be shielded to prevent the waste chips from splashing and affecting the operator. The top outer wall of the workbench 1 is provided with a fixing mechanism 2, and the fixing mechanism 2 can support and fix it from the inner ring of the bearing to prevent the bearing from being offset during the grinding process and affecting the grinding effect.
[0036] Reference Figure 2-Figure 4 The fixing mechanism 2 includes a chassis 201, which is fixedly connected to the top outer wall of the workbench 1. A card slot 202 is provided on the top outer wall of the chassis 201. There are multiple groups of card slots 202. The position of the rotating plate 206 can be fixed by the card slot 202. A fixed block 203 is fixedly connected to the top outer wall of the chassis 201. The fixed block 203 and the chassis 201 cannot rotate. A through groove 204 is provided on the outer wall of the fixed block 203. The through groove 204 can guide the movement of the arc block 205 so that it can keep moving toward the middle or the outside at the same time.
[0037] Reference Figure 2-Figure 4 The inner wall of the fixed block 203 is rotatably connected with a rotating plate 206, and a protrusion is arranged on one side of the rotating plate 206, and the protrusion penetrates the outer wall of one side of the fixed block 203. By turning the protrusion, the rotating plate 206 can be driven to rotate synchronously. An inclined groove 207 is provided on the outer wall of the rotating plate 206, and three groups of inclined grooves 207 and through grooves 204 are arranged. The inner wall of the inclined groove 207 is slidably connected with an arc block 205. When the fixed block 203 rotates, the inclined groove 207 squeezes the arc block 205, so that the arc block 205 moves in the inner wall of the inclined groove 207.
[0038] Reference Figure 2-Figure 4The arc block 205 is slidably connected to the inner wall of the through groove 204. When the arc block 205 moves along the inner wall of the inclined groove 207, it is guided by the through groove 204 and moves toward the middle or the outside at the same time. The distance between the arc blocks 205 can be adjusted to adapt to bearings with different inner diameters. A limit assembly is provided on the inner wall of the rotating plate 206. The rotating plate 206 can be fixed by the limit assembly to fix the positions of the three groups of arc blocks 205.
[0039] Reference Figure 3-Figure 4 The limit assembly includes a pull rod 302, which passes through the outer wall of the protrusion set on one side of the rotating plate 206. The pull rod 302 is elastically connected to the inner wall of the rotating plate 206 through a spring A301. When not affected by external forces, the pull rod 302 remains in a downward pop-up state due to the elastic force of the spring A301 and is engaged with the card slot 202. One end of the spring A301 is fixedly connected to the outer wall of the pull rod 302, and the other end of the spring A301 is fixedly connected to the inner wall of the rotating plate 206. The outer wall is slidably connected to the inner wall of the rotating plate 206. By pulling the pull rod 302 upward, the spring A301 is forced to shrink, and the pull rod 302 is disengaged from the slot 202, so that the limit of the rotating plate 206 can be released. The rotating plate 206 is rotated, and the pull rod 302 is engaged with the slot 202. Since there are multiple groups of slots 202, the rotating plate 206 can be rotated to multiple positions for fixing, thereby moving the three groups of arc blocks 205 to multiple positions for fixing, and bearings with different inner diameters can be supported and fixed.
[0040] Reference Figure 5-Figure 6 The shielding mechanism 4 includes a baffle 401, which is slidably connected to the inner wall of the connecting seat 6. The baffle 401 can move up and down to block waste chips, or move upward to maintain and replace the grinding disc 8. The outer wall of the baffle 401 is provided with a groove 402, and the position of the baffle 401 can be fixed by the groove 402. The outer wall of the baffle 401 is fixedly connected with a sliding plate 405, and the sliding plate 405 is arranged on the outer walls of both sides of the baffle 401. The sliding plate 405 is elastically connected to the inner wall of the connecting seat 6 through a telescopic spring 406. One end of the telescopic spring 406 is fixedly connected to the outer wall of the sliding plate 405, and the other end of the telescopic spring 406 is fixedly connected to the inner wall of the connecting seat 6. Through the telescopic spring 406, the sliding plate 405 and the baffle 401 can be kept in a downward moving state without being affected by external force, and the grinding disc 8 can be shielded.
[0041] Reference Figure 5-Figure 6 The sliding plate 405 is slidably connected to the inner wall of the connecting seat 6. When the cylinder 5 drives the connecting seat 6 to move downward until the grinding disc 8 contacts the bearing surface, the outer wall of the bottom end of the baffle 401 contacts the outer wall of the top end of the workbench 1 and moves upward. The telescopic spring 406 is forced to shrink, and the inner diameter of the baffle 401 is large, which can block the bearing, thereby preventing waste chips from splashing during grinding.
[0042] Reference Figure 5-Figure 6 The inner wall of the connecting seat 6 is elastically connected with a block 404 through a spring B403, one end of the spring B403 is fixedly connected to the outer wall of the block 404, and the other end of the spring B403 is fixedly connected to the inner wall of the connecting seat 6. By pulling the block 404 outward, the spring B403 is forced to shrink, and the baffle 401 can be moved upward, and the outer wall of the block 404 is slidably connected to the inner wall of the connecting seat 6, and the block 404 is engaged with the groove 402. When the baffle 401 moves to the position where the groove 402 corresponds to the block 404, the block 404 pops out and engages with the groove 402, so that the baffle 401 can be fixed. At this time, the grinding disc 8 is exposed to the outside and can be maintained and replaced.
[0043] Working principle: When in use, Figure 1 As shown, the bearing can be placed on the fixed block 203 first, so that the three groups of arc blocks 205 are all in the inner ring of the bearing, and then the pull rod 302 can be pulled to release the limit of the rotating plate 206, and the rotating plate 206 can be rotated clockwise, and the inclined groove 207 produces a squeezing force on the arc blocks 205, and the arc blocks 205 are moved outward at the same time through the guiding effect of the through groove 204. When the outer wall of the arc block 205 is in contact with the inner ring surface of the bearing, the pull rod 302 can be loosened to make the pull rod 302 02 As the spring A301 pops out and engages with the card slot 202, the rotating plate 206 is fixed, thereby fixing the three groups of arc blocks 205, so that the bearing can be supported and fixed from the inner ring, avoiding the problem of bearing force offset during the grinding process and affecting the grinding effect, and by rotating the rotating plate 206 to multiple angles for fixing, the three groups of arc blocks 205 can be moved to multiple positions for fixing, which can adapt to bearings with different inner ring diameters, with higher adaptability and more convenient and quicker adjustment process.
[0044] Then, the cylinder 5 can be used to drive the connecting seat 6 and the grinding disc 8 to move downward. When the grinding disc 8 moves to contact the bearing surface, the bottom end of the baffle 401 contacts the top end of the workbench 1 and blocks the bearing. At this time, the motor 7 can be started to drive the grinding disc 8 to rotate to grind the bearing. The waste chips generated by grinding cannot be splashed due to the blocking effect of the baffle 401, thereby avoiding the problem of waste chips flying out and causing harm to the operator. When the grinding disc 8 needs to be maintained and replaced, the block 404 can be pulled outward to open the baffle 401. Move upward, when the baffle 401 moves to the position corresponding to the groove 402 and the block 404, the block 404 pops out due to the elastic force of the spring B403 and engages with the groove 402, so that the baffle 401 can be limited. At this time, the grinding disc 8 is exposed to the outside, and the grinding disc 8 can be cleaned and replaced. The block 404 can be pulled outward to release the limit of the baffle 401, and the sliding plate 405 moves downward at the same time as the baffle 401 due to the elastic force of the telescopic spring 406, so that the grinding disc 8 and the bearing can be kept covered, which is convenient for the next processing.
[0045] 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.
