Description
Technical Field
[0001] This invention relates to the field of bearing processing equipment technology, specifically to equipment for precision machining of bearing inner and outer rings. Background Technology
[0002] As a core component in the industrial field, the machining quality of the inner and outer rings of bearings directly determines the performance, lifespan, and reliability of the entire mechanical system. The production of the inner and outer rings of bearings is a complex and precise process involving multiple procedures and high technical requirements. Among them, the raceways of the inner and outer rings of bearings need to be "ultra-precision machined," which is one of the most critical steps to ensure the performance, lifespan, and reliability of bearings.
[0003] The final finishing process in ultra-precision machining aims to obtain the final ideal working surface. The overall steps are as follows: In the intense cutting stage, the high pressure of the oilstone cuts and grinds the sharp peaks; in the intermediate cutting stage, the pressure of the oilstone decreases to form a cross-shaped pattern; in the finishing stage, the pressure of the oilstone is very light, mainly to reduce the roughness.
[0004] As can be seen from the above, the current bearing inner and outer rings have many processes and are relatively complex to operate. Moreover, due to the different raceway positions of the inner and outer rings, different equipment is required for processing, which increases the processing equipment and wear and tear, and also increases the processing time, greatly reducing production efficiency.

Detailed Implementation
[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Please see Figure 1-11This invention provides a technical solution comprising an outer shell 1, a drive assembly 2 connected to the bottom of the inner wall of the outer shell 1, a circular shaft 3 connected to the middle of the drive assembly 2, lifting assemblies 4 connected to the ends of the circular shaft 3 that are far apart from each other, and a common strip rod 5 connected to the ends of the circular shaft 3 that are close to each other. Motor frames 6 are slidably mounted on both ends of the strip rod 5, and limit tubes 61 are connected to one side of each motor frame 6. The limit tubes 61 are slidably connected to the strip rod 5. Through the shape of the limit tubes 61 and the motor frames 6, the motor frames 6 can slide up and down the strip rod 5. Simultaneously, as the strip rod 5 rotates with the round shaft 3, the limiting tube 61 can also drive the dual-axis motor 7 inside the motor frame 6 to rotate, ensuring stable operation and synchronization. The dual-axis motor 7 is connected to the side of the motor frame 6 closest to each other. Each output end of the dual-axis motor 7 is connected to a drive shaft 8. Electric actuators 9 are connected to the ends of the drive shafts 8 furthest from each other. Universal joints 10 are connected to the ends of the electric actuators 9 furthest from each other. Oilstone wheels 11 are connected to the ends of the universal joints 10 furthest from each other. The inner support structure 12 and the universal joint 10 are both connected to an adjustment component 13. The oilstone wheel 11 is used to process the outer ring of the bearing, and the inner support structure 12 is used to process the inner ring of the bearing. Support seats 14 are connected to both sides of the bottom inner side of the outer housing 1. Guide rails 15 are connected to the top of the support seats 14. A ramp rail 16 is provided at one end of each guide rail 15. The inner and outer rings of the bearing are fed through the ramp rail 16, allowing them to roll freely into the outer housing 1 for processing. The outer housing 1 has corresponding inlet and outlet ports on both sides. As can be seen from the attached drawings, a control panel is connected to one side of the outer housing 1. Since this is a standard setting, it is not described in detail in the manual. Limiting components 17 are provided in the middle of the guide rails 15. A reciprocating component 19 is connected to one side of the inner wall of the outer housing 1. An auxiliary positioning component 18 is connected to one side of the reciprocating component 19. The auxiliary positioning component 18 is connected to the limiting component 17 on the side used for outer ring processing. An inner ring grinding component 20 is connected to the other side of the inner wall of the outer housing 1. An auxiliary positioning structure 24 is connected to the bottom of the inner wall of the outer housing 1 corresponding to the drive component 2. Reference Figure 1 and Figure 2As shown, a water tank 25 is connected to the bottom of the outer casing 1 for cooling during processing. A filter screen 251 is connected between the inner walls of the water tank 25, and filter cotton 26 is placed above the filter screen 251. A water pump 27 is connected to one side of the water tank 25, and a drain pipe 28 is connected to the outlet of the water pump 27. A branch pipe 29 is connected to one side of the drain pipe 28, and one end of the branch pipe 29 extends into the outer casing 1 and is connected to a nozzle. The outer casing 1 is close to the water tank 25. A drain hole 111 is provided on the side. As can be seen from the attached drawing, the two sets of branch pipes have different shapes and are aligned with the processing position. When the inner and outer rings are being precision machined, the water pump 27 draws water from the water tank 25 and discharges it to the branch pipe 29 through the drain pipe 28. The water is then sprayed out by the nozzle towards the processing position. The sprayed water flows back into the water tank 25 through the drain hole 111. The metal debris in the water is filtered out by the filter cotton 26 and the filter screen 251 and then flows back into the water tank 25 for recycling. Reference Figure 7 As shown, the drive assembly 2 includes a gantry inner frame 201 fixedly mounted on the bottom of the inner wall of the outer housing 1. Multiple sets of synchronous pulleys 202 are rotatably arranged between the inner sides of the gantry inner frame 201. A rotating gear ring 204 meshes with the synchronous pulleys 202 located inside the gantry inner frame 201. A three-pronged bracket 205 is connected to the inner ring of the rotating gear ring 204. A connecting shaft 203 is connected to the side of the synchronous pulleys 202 between two gantry inner frames 201 that are close to each other. A drive motor 206 is connected to one side of the gantry inner frame 201. The output end is connected to one of the synchronous pulleys 202. The round shaft 3 is fixedly connected to the tripod 205. The auxiliary positioning structure 24 is located below the drive assembly 2. When the drive motor 206 is started, it drives one of the synchronous pulleys 202 to rotate. Through the connection of the connecting shaft 203, it drives the synchronous pulleys 202 in the inner frame 201 of the gantry to rotate, thereby driving the rotating gear ring 204 to rotate. The rotating gear ring 204 drives the round shaft 3 to rotate through the inner tripod 205. The arrangement of multiple synchronous pulleys 202 also plays a supporting and limiting role for the rotating gear ring 204. Reference Figure 4 As shown, the inner ring grinding assembly 20 includes a fixing rod 21 fixedly installed on one side of the inner wall of the outer housing 1. A circular frame 22 is connected to one end of the fixing rod 21, and an oilstone ring 23 is connected to the inner ring of the circular frame 22. The circular frame 22 is fixed to one side of the inner wall of the outer housing 1 by the fixing rod 21. After the inner support structure 12 fixes the inner ring of the extracted bearing, it moves to the inside of the oilstone ring 23. Driven by the dual-axis motor 7, the high-speed rotating inner ring of the bearing actively approaches the oilstone ring 23 to perform fine machining on the raceway. The oilstone ring 23 and the outer ring of the bearing are concentric. The oilstone ring 23 of the appropriate size can be replaced according to the size of the inner ring of the bearing to meet the processing effect.
[0021] Reference Figure 11As shown, the auxiliary positioning structure 24 includes a side plate 241 connected to the bottom of the inner wall of the outer housing 1. A cylinder 242 is connected to one side of the side plate 241. The output end of the cylinder 242 passes through the side plate 241 and is connected to a clamping plate 243. The rotating gear ring 204 is located between the clamping plates 243. Before the finishing work is carried out, the inner and outer rings of the corresponding bearings must be pre-positioned and adjusted. During this period, the cylinder 242 will push the clamping plate 243 to clamp and fix the corresponding rotating gear ring 204 to ensure the stability of the preparation work. When the finishing work begins, the clamping plate 243 is released, and the rotating gear ring 204 begins to rotate to carry out the full machining work.
[0022] Reference Figure 6 As shown, the inner support structure 12 includes a sleeve 121 and a top plate 122. Multiple sets of connecting rods 123 are rotatably arranged on the outer rings of both the sleeve 121 and the top plate 122. A support plate 124 is rotatably arranged at one end of each connecting rod 123 that is close to the other. A telescopic rod 125 is connected between the sleeve 121 and the top plate 122. The sleeve 121 is fixedly connected to the telescopic rod 125, and one end of the telescopic rod 125 is fixedly connected to a universal joint 10. An anti-slip layer 126 is provided on the surface of the support plate 124. The bearing inner ring moves along the guide rail 15 to the corresponding limiting component 1. After the 7th part is fixed, the electric push rod 9 located on one side of the inner support structure 12 extends and pushes the inner support structure 12 to insert into the inner ring of the bearing. Then the telescopic rod 125 retracts, driving the top plate 122 to move towards the sleeve 121. The outer connecting rod 123 rotates, pushing the support plate 124 to press against the inner wall of the inner ring. The anti-slip layer 126 plays an anti-slip and stabilizing role. After the inner support structure 12 fixes the inner ring of the bearing, the electric push rod 9 retracts, driving the inner ring of the bearing to move to the inside of the oilstone ring 23. The vertical position of the inner support structure 12 can be adjusted by the lifting assembly 4. The adjusting assembly 13 includes a connecting seat 131 rotatably mounted at one end of the universal joint 10, a tube frame 132 fixedly mounted on one side of the lifting assembly 4, and a stop 135 rotatably mounted at the other end of the universal joint 10. An adjusting push rod 134 is rotatably mounted between the stop 135 and the connecting seat 131. As shown in the attached figure, both ends of the adjusting push rod 134 are connected to connecting ball heads. The two ends of the adjusting push rod 134 are rotatably connected to the corresponding connecting seat 131 and the stop 135 through the connecting ball heads, thereby satisfying the work of multi-directional angle adjustment. A connecting rod 133 is connected to one side of the connecting seat 131. One end of the connecting rod 133 is slidably connected to the tube frame 132. During the finishing work, the angle of the stop 135 can be adjusted by extending and retracting the different lengths of the multiple sets of adjusting push rods 134. Then, through the universal joint 10, the angle of the oilstone wheel 11 or the corresponding inner support structure 12 can be adjusted to perform work at different angles, ensuring the comprehensiveness of the machining of the inner and outer raceways of the bearing.
[0023] Reference Figure 8 As shown, the lifting assembly 4 includes a connecting rod 401, with a hanger 41 connected to both ends of the connecting rod 401. A guide roller 42 is rotatably mounted between the inner sides of the hangers 41. A guide hole 43 is opened on the inner side of the hanger 41, and a connecting bolt 44 is slidably mounted inside the guide hole 43. A lifting bearing 45 is connected to one end of the connecting bolt 44 that is close to each other. The inner ring of the lifting bearing 45 is connected to the drive shaft 8. A traction belt 46 is connected to one side of the connecting bolt 44, and a traction device is connected to the middle of the traction belt 46. The traction head 47 has a traction belt 46 extending through its bottom end and is connected to a telescopic rod 48. A guide rod 49 is slidably mounted on the inner side of the hanger 41. An arc-shaped plate 50 is connected to the bottom end of the guide rod 49, and a return spring 51 is sleeved and connected to the top end of the guide rod 49. The return spring 51 is a high-carbon steel spring with a high stiffness coefficient. An electromagnet 52 is connected to the inner side of the hanger 41. The retraction of the telescopic rod 48 pulls the traction belt 46 through the traction head 47, and the traction is guided by the guide roller 42. The guide belt 46 pulls the connecting bolt 44 to slide upward along the guide hole 43, thereby adjusting the position of the swivel bearing 45. The swivel bearing 45 pulls the drive shaft 8, thereby adjusting the position of the oilstone wheel 11 and the inner support structure 12, changing the working radius, and thus making it suitable for processing the inner and outer rings of bearings of various sizes. In the initial position, the swivel bearing 45 is in contact with 52, and the arc plate 50 is against the other side of the swivel bearing 45. When adjustment and movement are required, 52 is de-energized, losing its attraction to the swivel bearing 45. Then, as the swivel bearing 45 moves, it pushes the arc plate 50, which in turn pushes the guide rod 49 to slide upward, thereby stretching the return spring 51. Through the rebound traction of the return spring 51, the guide rod 49 generates a reaction force, which causes the arc plate 50 to provide a reverse force to the swivel bearing 45, thereby ensuring the stable movement of the swivel bearing 45 and ensuring the stability of the processing. At the same time, it can also avoid excessive force during bearing processing, causing over-processing, which is also a protection mechanism.
[0024] Reference Figure 9As shown, the limiting component 17 includes an auxiliary rail 171 disposed in the middle of the guide rail 15. A recessed frame 172 is connected to the bottom end of the auxiliary rail 171. A telescopic rod 173 is rotatably disposed inside the recessed frame 172. A clamping plate 174 is rotatably disposed at the other end of the telescopic rod 173. An infrared sensor 175 is connected to one side of the auxiliary rail 171. When the bearing rolls along the guide rail 15 to the position of the infrared sensor 175, the telescopic rod 173 extends and pushes the clamping plate 174 to rotate, thereby limiting the bearing and preventing it from rolling. As can be seen from the attached figure, the clamping plate 174 has an arc surface on one side corresponding to the inner and outer rings that are pulled out. In order to achieve a better fit and a limiting effect with the inner and outer rings of the bearing, after the processing is completed, the telescopic rod 173 pulls the clamping plate 174 to reset, so that the processed bearing rolls out. The auxiliary rail 171 in the limiting component 17 located at the inner ring processing position of the bearing is fixedly connected to the corresponding support seat 14. The limiting component 17 located at the outer ring processing position of the bearing is not connected to the support seat 14, but is slidably connected to the corresponding guide rail 15, so as to satisfy the pulling effect of the reciprocating component 19. The auxiliary rail 171 located on one side of the inner support structure 12 has a notch on one side, which facilitates the movement of the inner ring of the bearing into the oilstone ring 23. The auxiliary positioning component 18 includes a ring frame 181, a cross frame 182 connected to the top of the ring frame 181, a cylinder 183 connected to the top of the cross frame 182, the output end of the cylinder 183 passing through the cross frame 182 and connected to an outer ring holder 184, and an adhesive layer 185 connected to the inner side of the outer ring holder 184. The reciprocating component 19 is connected to the ring frame 181. When the outer ring of the bearing is limited by the corresponding limiting component 17, the cylinder 183 extends and pushes the outer ring holder 184 to lock above the outer ring of the bearing. The adhesive layer 185 plays a role in fastening and anti-slip, further limiting and fixing the outer ring of the bearing to ensure stability during processing.
[0025] Reference Figure 10As shown, the reciprocating assembly 19 includes a movable frame 191 fixedly mounted on one side of the ring frame 181. A guide frame 192 is slidably mounted on one side of the movable frame 191. A horizontal plate 193 is connected to one end of the guide frame 192, and the other end of the guide frame 192 passes through the movable frame 191 and is fixedly mounted on one side of the inner wall of the outer housing 1. A servo motor 194 is connected to one side of the horizontal plate 193. The output end of the servo motor 194 passes through the horizontal plate 193 and is connected to a threaded post 195. An internal threaded sleeve 196 is connected to the inner side of the movable frame 191 corresponding to the threaded post 195. A traction spring 222 is connected to one side of the horizontal plate 193 corresponding to the internal threaded sleeve 196. The traction spring 222 is sleeved on the outer ring of the threaded post 195, and one end is fixedly connected to the internal threaded sleeve 196. When the servo motor 194 drives the threaded post 195 to rotate relatively slowly... The threaded column 195, through its threaded connection with the internal threaded sleeve 196, pushes the internal threaded sleeve 196 to move, which in turn drives the ring frame 181 and the auxiliary rail 171 to move via the movable frame 191. As the rotation continues, since the number of threads in the threaded column 195 and the internal threaded sleeve 196 is less than one turn, the continuous rotation will cause the threads to disconnect. Due to the traction pull of the traction spring 222, the threaded column 195 and the internal threaded sleeve 196 will move back to their original positions. A damping sleeve 197 is connected to one side of the horizontal plate 193, and a damping rod 198 is connected to one side of the movable frame 191 corresponding to the damping sleeve 197. Through the connection of the damping sleeve 197 and the damping rod 198, the movable frame 191 can maintain a slow moving speed when it reciprocates along the traction ring frame 181 and the auxiliary rail 171, ensuring stability during processing.
[0026] The implementation principle of this application is as follows: When in use, the inner and outer rings of the bearing are placed on the corresponding ramp rail 16 and enter the outer housing 1 along the guide rail 15. When the inner and outer rings of the bearing enter the limiting component 17 and are detected by the infrared sensor 175, the telescopic rod 3 173 will push the clamping plate 174 to open, positioning the bearing outer ring in position. The auxiliary positioning component 18 located above the bearing outer ring will fix the top of the bearing outer ring. Then, the electric push rods 9 on both sides extend and push the oilstone wheel 11 into the raceway of the bearing outer ring. At the same time, the inner support structure 12 moves into the bearing inner ring and opens and fixes it. Then, the electric push rod 9 retracts and drives the bearing inner ring into the oilstone ring 23. Then, the telescopic rod 1 48 extends and releases the traction belt 46. The elasticity of the return spring 51 will pull the guide rod 49, which will push the hanging bearing 45 down through the arc plate 50, thereby pushing it downward. The drive shaft 8 is moved, and the oilstone wheel 11 is adjusted to fit against the raceway of the outer ring of the bearing. The inner support structure 12, along with the raceway of the inner ring of the bearing, fits against the surface of the oilstone ring 23. Then, the dual-shaft motor 7 starts and drives the drive shaft 8 to rotate. Through the electric push rod 9 and the universal joint 10, the oilstone wheel 11 and the inner support structure 12 are rotated for machining. Then, the drive motor 206 starts and makes the rotating gear ring 204 rotate. The three-pronged bracket 205 drives the round shaft 3 to rotate. While the round shaft 3 drives the lifting assembly 4 to rotate, it drives the motor frame 6 to rotate through the inner bar 5. This causes the dual-shaft motor 7 and the drive shaft 8 to rotate around the axis of the round shaft 3, performing comprehensive machining on the inner and outer rings of the bearing. At the same time, the angle between the oilstone wheel 11 and the inner ring of the bearing can be adjusted by the adjusting assembly 13. With the drive of the drive assembly 2, the inner and outer rings of the bearing can be precisely and comprehensively machined.
