Description

Technical Field

[0001] This utility model relates to the technical field of high-efficiency grinding equipment for inner and outer rings of bearings, and in particular to a high-efficiency grinding equipment for inner and outer rings of deep groove ball bearings. Background Technology

[0002] Bearing grinding equipment is a type of machinery specifically designed for processing and grinding the inner ring, outer ring, and ball bearing components to ensure surface smoothness, dimensional accuracy, and geometric precision, thereby ensuring good performance and long service life of the bearing during operation.

[0003] Existing bearing grinding equipment includes internal and external cylindrical grinding machines. Internal cylindrical grinding machines are specifically used for grinding the inner ring of bearings, while external cylindrical grinding machines are used for grinding the outer ring of bearings. A bearing has an inner and an outer ring. After the inner ring of a bearing is ground on an internal cylindrical grinding machine, it still needs to be transferred to an external cylindrical grinding machine for fixing and grinding. A bearing needs to be transferred, fixed, and ground on two machines, which prolongs the production cycle and reduces production efficiency. Therefore, there is a need to propose a new type of high-efficiency grinding equipment for the inner and outer rings of deep groove ball bearings. Utility Model Content

[0004] This utility model mainly provides a high-efficiency grinding equipment for the inner and outer rings of deep groove ball bearings, which can conveniently improve processing efficiency and reduce production cycle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency grinding device for the inner and outer rings of a deep groove ball bearing, comprising a worktable and a bearing body, wherein a grinding assembly is provided on the outer surface of the worktable, the grinding assembly includes a motor, an output shaft is fixedly connected to the output end of the motor, a first grinding head is fixedly connected to one end of the output shaft, a first gear is fixedly sleeved on the outer surface of the output shaft, a fixed shaft is movably embedded on one side of the outer surface of the worktable, a second gear is fixedly sleeved on the outer surface of the fixed shaft near one end, and a second grinding head is fixedly sleeved on the outer surface of the fixed shaft.

[0006] Preferably, the motor is disposed on the outer surface of the workbench, and the outer surface of the first gear meshes with the outer surface of the second gear. When the first gear rotates, it drives the second gear to rotate.

[0007] Preferably, a fixing block is fixedly connected to the outer surface of the other side of the workbench, a fixing sleeve is fixedly connected to the outer surface of the fixing block, and a first clamping head is rotatably connected to the inner wall of the fixing sleeve. The first clamping head can rotate on the inner wall of the fixing sleeve.

[0008] Preferably, a hydraulic rod is provided on the outer surface of the other side of the workbench, and a moving block is fixedly connected to one end of the hydraulic rod. Through the fixed connection of the moving block to one end of the hydraulic rod, the hydraulic rod can drive the moving block to move.

[0009] Preferably, a movable sleeve is fixedly connected to the outer surface of the movable block, and a second clamping head is rotatably connected to the inner wall of the movable sleeve. The second clamping head can rotate on the inner wall of the movable sleeve.

[0010] Preferably, the inner walls of the first clamping head and the second clamping head are both fixedly connected to a toothed rack near one edge, and the outer surface of the fixed shaft is fixedly fitted with two third gears. By fixing the toothed racks to the inner walls of the first clamping head and the second clamping head, the first clamping head and the second clamping head can be driven to rotate.

[0011] Preferably, the outer surfaces of the two third gears mesh with the outer surfaces of the two gear rows respectively, and the outer surfaces of the bearing body are in contact with the outer surfaces of the first clamping head and the second clamping head respectively. Because the third gear meshes with the outer surfaces of the gear rows, the third gear can drive the gear rows to rotate when it rotates.

[0013] 1. In this utility model, by setting up a grinding assembly, the motor will simultaneously drive the first grinding head and the second grinding head to rotate. The first grinding head grinds the outer circle of the bearing, and the second grinding head grinds the inner circle of the bearing. By grinding the inner and outer rings of the bearing simultaneously by the first grinding head and the second grinding head, the time for transferring, fixing and grinding the bearing on the two machines is reduced, thereby shortening the production cycle and improving production efficiency.

[0014] 2. In this utility model, by setting a gear rack and a third gear, when the third gear rotates, it will drive the gear rack to rotate. When the gear rack rotates, it will simultaneously drive the first clamping head and the second clamping head to rotate. When the first clamping head and the second clamping head rotate, they will drive the bearing to rotate, thereby enabling multi-area grinding of the bearing and improving the surface quality of the bearing.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a high-efficiency grinding device for the inner and outer rings of a deep groove ball bearing, comprising a worktable 1 and a bearing body 12, characterized in that: a grinding component 2 is provided on the outer surface of the worktable 1, the grinding component 2 includes a motor 201, an output shaft 202 is fixedly connected to the output end of the motor 201, a first grinding head 203 is fixedly connected to one end of the output shaft 202, a first gear 204 is fixedly sleeved on the outer surface of the output shaft 202, a fixed shaft 205 is movably embedded on one side of the outer surface of the worktable 1, a second gear 206 is fixedly sleeved on the outer surface of the fixed shaft 205 near one end, and a second grinding head 207 is fixedly sleeved on the outer surface of the fixed shaft 205.

[0023] like Figure 1-2 As shown, the motor 201 is mounted on the outer surface of the workbench 1. The outer surface of the first gear 204 meshes with the outer surface of the second gear 206. When the first gear 204 rotates, it will drive the second gear 206 to rotate.

[0024] like Figure 1-3As shown, a fixing block 3 is fixedly connected to the outer surface of the other side of the workbench 1, and a fixing sleeve 4 is fixedly connected to the outer surface of the fixing block 3. A first clamping head 5 is rotatably connected to the inner wall of the fixing sleeve 4. The first clamping head 5 can rotate on the inner wall of the fixing sleeve 4.

[0025] like Figure 1-2 As shown, a hydraulic rod 6 is provided on the outer surface of the other side of the workbench 1. A movable block 7 is fixedly connected to one end of the hydraulic rod 6. The hydraulic rod 6 can drive the movable block 7 to move.

[0026] like Figure 1-3 As shown, a movable sleeve 8 is fixedly connected to the outer surface of the movable block 7, and a second clamping head 9 is rotatably connected to the inner wall of the movable sleeve 8. The second clamping head 9 can rotate on the inner wall of the movable sleeve 8.

[0027] like Figure 3-4 As shown, toothed racks 10 are fixedly connected to the inner walls of the first clamping head 5 and the second clamping head 9 near one edge. Two third gears 11 are fixedly sleeved on the outer surface of the fixed shaft 205. By fixing toothed racks 10 to the inner walls of the first clamping head 5 and the second clamping head 9, the first clamping head 5 and the second clamping head 9 can be driven to rotate.

[0028] like Figure 1-4 As shown, the outer surfaces of the two third gears 11 mesh with the outer surfaces of the two gear rows 10 respectively. The outer surfaces of the bearing body 12 are in contact with the outer surfaces of the first clamping head 5 and the second clamping head 9 respectively. Because the third gears 11 mesh with the outer surfaces of the gear rows 10, the third gears 11 can drive the gear rows 10 to rotate when they rotate.

[0029] The usage and working principle of this device: When using a high-efficiency grinding device for the inner and outer rings of a deep groove ball bearing, the operator first places the bearing body 12 on top of the first clamping head 5, then activates the hydraulic rod 6. The hydraulic rod 6 drives the moving block 7 to move, the moving block 7 drives the moving sleeve 8 to move, and the moving sleeve 8 drives the second clamping head 9 to move until the outer surface of the second clamping head 9 is in contact with the outer surface of the bearing body 12. At this time, the bearing body 12 is effectively clamped between the outer surfaces of the second clamping head 9 and the first clamping head 5. Then, the operator activates the motor 201, which drives the output shaft 202 to rotate. When the output shaft 202 rotates, it simultaneously drives the first grinding head 203 and the first gear 204 to rotate. When the first grinding head 203 rotates, it grinds the outer circle of the bearing body 12. When the first gear 204 rotates, it drives the second gear 206 to rotate. When the second gear 206 rotates, it drives the fixed shaft 205 to rotate. The outer surface of the fixed shaft 205 will grind the inner wall of the worktable 1. The bearing body 12 rotates, and the fixed shaft 205 drives the second grinding head 207 to grind the inner circle of the bearing body 12. The fixed shaft 205 also drives the two third gears 11 to rotate. The outer surface of the third gear 11 rotates along the outer surface of the gear rack 10, thereby driving the gear rack 10 to rotate. When the two gear racks 10 rotate, they will drive the first clamping head 5 and the second clamping head 9 to rotate respectively. The outer surface of the first clamping head 5 rotates along the inside of the fixed sleeve 4, and the outer surface of the second clamping head 9 rotates along the inner wall of the movable sleeve 8. When the first clamping head 5 and the second clamping head 9 rotate simultaneously, they will drive the bearing body 12 to rotate. The first grinding head 203 grinds the outer circle of the bearing body 12, and the second grinding head 207 grinds the inner circle of the bearing body 12. Thus, the inner and outer circles of the bearing body 12 can be ground simultaneously, solving the problem that a bearing body 12 needs to be transferred, fixed and ground on two machines, thereby extending the production cycle and reducing production efficiency.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
