[0002] An industrial robot is a multi-joint manipulator or a multi-degree-of-freedom machine device widely used in the industrial field. It has a certain degree of automation and can realize various industrial processing and manufacturing functions relying on its own power source and control ability. A spindle bearing cold pressing and assembling industrial robot is a device specially used for the cold assembly (pressing) process of bearings and spindles. It is usually applied in fields such as mechanical manufacturing, the automotive industry, and electric motor manufacturing.

[0003] For example, the invention patent with the publication number CN109262244B discloses a bearing pressing device. This invention patent bearing pressing device alleviates the technical problem that the devices for assembling bearings in the prior art are difficult to be applicable to casings with different shapes, which affects the bearing assembly efficiency. However, when this invention patent is in use, the positioning between the bearing and the spindle may be deviated due to the position offset when placing the bearing and the spindle, resulting in damage to the spindle or the bearing during the pressing process. It may also cause scratches on the surface of the spindle or the bearing during the pressing process due to insufficient lubrication or foreign matters remaining uncleaned on the spindle and the bearing.

[0012] Further, a cleaning motor is fixedly installed on the outer wall of one side of the bracket. A driving gear is connected to the output shaft at the top of the cleaning motor. The driving gear is engaged with the toothed ring.

[0013] Further, water tanks are symmetrically fixedly connected to the surface of the base, and a water pump is connected to one side of each water tank. A water delivery pipe is connected to one side of the water pump.

[0014] Further, a sliding seat is snap-fitted and slidably connected inside the slide rail. A through groove is arranged in the middle of the sliding seat.

[0015] Further, a cleaning plate is connected to one side of the sliding seat. An oil chamber is arranged on one side of the cleaning plate.

Brush plates are connected to both sides of the cleaning plate. The oil chamber is communicated with the through groove. The cleaning chamber is communicated with the water delivery pipe through the sleeve.

[0016] The present invention provides a cold-pressing assembly industrial robot for a spindle bearing, which has the following beneficial effects: during use, it can synchronously position the spindle and the bearing to ensure the coincidence of their central axes, avoiding the failure of cold pressing or damage to the spindle and the bearing due to position deviation during cold pressing. Moreover, before cold pressing, it can synchronously clean and lubricate the spindle and the bearing to ensure the smoothness of the cold pressing process and avoid scratches on the spindle and the bearing during cold pressing due to impurities on the surface.

[0017] 1. During use of the present invention, in actual industrial production, this industrial robot plays a key role. The operator passes the spindle through the bracket and places it on the material placing plate, and suspends the spindle between the second clamping plates. After starting the driving motor, the driving motor can drive the double-link gear disk to rotate in the rotating groove through the driving wheel, and then drive the lead screw to rotate in the sliding groove through the transmission wheel, so that the lead screw drives the support rod to synchronously move towards the double-link gear disk in the sliding groove. The first clamping plate and the second clamping plate follow the support rod to synchronously move towards the center of the chassis, respectively clamping the spindle and the bearing, and simultaneously performing concentric positioning on the spindle and the bearing to ensure the coincidence of their central axes, avoiding the failure of cold pressing or damage to the spindle and the bearing due to position deviation during cold pressing. After the centering clamping is completed, the lifting rod drives the second clamping plate to synchronously descend, so that the bearing can approach the spindle while keeping the central axes coincident. The limiting rod can limit the second clamping plate through the limiting hole to avoid the second clamping plate being deflected during movement, resulting in inaccurate positioning. In summary, during use, it can synchronously position the spindle and the bearing to ensure the coincidence of their central axes, avoiding the failure of cold pressing or damage to the spindle and the bearing due to position deviation during cold pressing.

[0018] 2. After the industrial robot firmly clamps the main shaft and the bearing, during the process of the lifting rod driving the second clamping plate to descend, the cleaning motor can drive the driving gear to rotate, so that the toothed ring drives the linkage plate to rotate on the base. During this process, when the linkage plate of the industrial robot moves, it can press the sliding seat to slide on the base along the slide rail, so that the sliding seat drives the cleaning plate to approach the main shaft. When the toothed ring rotates, the limiting block can limit the linkage plate through the limiting groove, preventing the linkage plate and the toothed ring from falling off the base during rotation, and also preventing the toothed ring from shifting during rotation, resulting in the inability to drive the sliding seat to move synchronously. The slide rail can limit the sliding seat to prevent the sliding seat from skewing during movement. After the cleaning plate presses one side of the brush plate against the main shaft, the cleaning motor stops running, and the lifting rod drives the second clamping plate to continue descending, so that the bearing sleeve is on the outside of the cleaning plate, and the brush plate on the other side of the cleaning plate fits against the inner ring of the bearing. Then the cleaning motor drives the driving gear to rotate again, causing the toothed ring to drive the linkage plate to move again. At this time, the sliding seat cannot continue to move within the slide rail, so that the toothed ring can drive the base to rotate on the bracket through the sliding seat, thereby enabling the cleaning plate to clean and lubricate the pressing area of the main shaft and the bearing. In actual industrial applications, such as the bearing assembly link in a machining workshop, this industrial robot can automatically complete the cleaning and lubrication work of the main shaft and the bearing, replacing the traditional manual cleaning method, not only improving work efficiency, but also ensuring the quality of cleaning and lubrication, providing good conditions for subsequent pressing work.

[0019] 3. When the present invention is being cleaned, the oil in the oil chamber enters the annular groove, which can provide lubrication for the rotation of the base, making its rotation smooth. At the same time, the water pump can send the cleaning liquid from the water supply pipe through the sleeve into the cleaning plate, and then spray it from the spray nozzle into the cleaning chamber onto the main shaft and bearings. As the toothed ring drives the base to rotate, the brush plate can clean the pressing area of the main shaft and bearings. After the cleaning is completed, the water pump stops running. At the same time, by continuously sending oil into the oil chamber, the oil in the oil chamber can overflow and enter the oil groove through the through hole, then enter the oil chamber through the through oil pipe and the through groove, and finally be sprayed onto the main shaft and bearings through the spray nozzle to lubricate the pressing area, avoiding scratches on the main shaft and bearings due to excessive friction or impurities on the surface during pressing. The through groove and the sleeve can not only keep the connection between the cleaning plate and the through oil pipe and the water supply pipe before and after the sliding seat moves, but also restrict the sliding seat through the through oil pipe and the water supply pipe, further preventing the sliding seat from tilting. After the cleaning and lubrication are completed, the lifting rod first drives the second clamping plate to rise to disengage the bearing from the cleaning plate, and then the cleaning motor drives the toothed ring to reset through the driving gear. The sliding seat can drive the cleaning plate to reset under the action of the return spring. Then the lifting rod drives the second clamping plate to descend again, making the main shaft contact the bearing. Then the pressing rod drives the pressing plate to descend, and the bearing can be pressed onto the main shaft through the pressing plate. During pressing, the telescopic rod can drive the material placing plate to rise and fall, thereby adjusting the height of the upper end of the main shaft, and further adjusting the moving distance of the pressing plate to avoid excessive movement of the pressing plate causing pressure damage to the main shaft and bearings. In summary, during use, the main shaft and bearings can be cleaned and lubricated synchronously, ensuring the smoothness of the pressing process and avoiding scratches on the main shaft and bearings during pressing due to impurities on the surface.

Detailed implementation manners

[0029] Please refer to Figures 1 to 8, the present invention provides a technical solution: a spindle bearing cold-pressing assembly industrial robot, including a chassis 1 and a positioning component 2. The positioning component 2 is arranged above the chassis 1. The positioning component 2 includes a rotating groove 201, a sliding groove 202, a double-connected gear disk 203, a driving wheel 204, a driving motor 205, a lead screw 206, a transmission wheel 207, a support rod 208, a first clamping plate 209, a lifting rod 210, a limiting rod 211, a second clamping plate 212 and a limiting hole 213. A rotating groove 201 is opened in the middle of the chassis 1, and sliding grooves 202 are symmetrically opened around the rotating groove 201. A double-connected gear disk 203 is rotatably connected in the rotating groove 201, and a driving wheel 204 is arranged on one side of the double-connected gear disk 203. A driving motor 205 is connected to one side of the driving wheel 204. A lead screw 206 is rotatably connected in the sliding groove 202, and a transmission wheel 207 is connected to one side of the lead screw 206. A support rod 208 is arranged in the sliding groove 202, and a first clamping plate 209 is connected to one end of the support rod 208. A lifting rod 210 is connected to one side of the first clamping plate 209, and a limiting rod 211 is connected to the same side of the first clamping plate 209. A second clamping plate 212 is connected to one end of the lifting rod 210. Triangular notches are provided at the ends of the above-mentioned first clamping plate 209 and second clamping plate 212 facing the center of the chassis 1. The function of the triangular notches is to abut against the outer walls of the spindle and the bearing. And an anti-slip rubber pad is arranged on the outer surface of the triangular notches to increase the friction force during contact, ensure the clamping stability, and prevent wear on the spindle and the bearing. At the same time, both the first clamping plate 209 and the second clamping plate 212 are composed of two movable plates connected by connecting threaded rods inside. Before use, the length of the first clamping plate 209 and the second clamping plate 212 can be finely adjusted through the threaded rods, so as to be pre-adjusted according to the outer diameter dimensions of the spindles and bearings of this batch before use. And a limiting hole 213 is opened on one side of the second clamping plate 212.

[0030] Please refer to Figures 1 to 5, the driving wheel 204 and the transmission wheel 207 are both engaged with the double-connected gear disc 203. The support rod 208 is slidably connected to the chassis 1 through the chute 202. The support rod 208 is threadedly connected to the lead screw 206. The second clamping plate 212 is slidably connected to the limiting rod 211 through the limiting hole 213. The center of the chassis 1 is connected with a telescopic rod 3, and the upper end of the telescopic rod 3 is connected with a material placing plate 4. One side of the chassis 1 is connected with a cross beam 5, and a pressing rod 6 is connected below the cross beam 5. A pressing plate 7 is connected below the pressing rod 6. A bracket 8 is arranged above the chassis 1, and an annular groove 9 is arranged inside the bracket 8. An oil cavity 10 is arranged outside the annular groove 9. A base 11 is snap-fitted and connected inside the annular groove 9, and through holes 12 are symmetrically formed in the outer side of the lower part of the base 11. An oil groove 13 is formed in the outer side of the base 11, and slide rails 14 are symmetrically formed on the surface of the base 11. An oil pipe 15 is connected inside the slide rails 14, and the oil groove 13 is communicated with the oil cavity 10 through the through holes 12. The oil groove 13 is communicated with the oil pipe 15. Limiting blocks 16 are symmetrically connected to the surface of the base 11, and a toothed ring 17 is arranged on one side of the base 11. A linkage plate 18 is arranged inside the toothed ring 17, and a limiting groove 19 is formed on the surface of the linkage plate 18. The linkage plate 18 is slidably connected to the limiting block 16 through the limiting groove 19. A cleaning motor 21 is fixedly installed on the outer wall of one side of the bracket 8. A driving gear 20 is connected to the output shaft at the top of the cleaning motor 21. The driving gear 20 is meshed with the toothed ring 17;

[0031] The specific operation is as follows. When in use, the staff passes the main shaft through the center of the bracket 8, places its bottom end horizontally on the material placing plate 4, and positions the main shaft between each second clamping plate 212. Subsequently, the driving motor 205 is started through an external controller. The driving motor 205 can drive the double gear disk 203 to rotate in the rotating groove 201 through the driving wheel 204, and then drive each lead screw 206 to rotate synchronously in the sliding groove 202 through the transmission wheel 207, causing each lead screw 206 to drive the corresponding support rod 208 to move horizontally synchronously in the corresponding sliding groove 202 towards the direction of the double gear disk 203. Further, it prompts the first clamping plate 209 and the second clamping plate 212 to move synchronously towards the center of the chassis 1. Since the distances from the ends of the first clamping plate 209 and the second clamping plate 212 facing the center of the chassis 1 to the center of the chassis 1 are different, when the first clamping plate 209 and the second clamping plate 212 move synchronously, they can respectively clamp the main shafts and bearings with different diameters, and at the same time perform concentric positioning on the main shaft and the bearing, ensuring the coincidence of their central axes, and avoiding the failure of press-fitting or damage to the main shaft and bearings due to position deviation during press-fitting. After the centering clamping is completed, the lifting rod 210 drives the second clamping plate 212 to descend synchronously, enabling the bearing to approach the main shaft while maintaining the coincidence of the central axes. The limiting rod 211 can limit the second clamping plate 212 through the limiting hole 213, preventing the second clamping plate 212 from deflecting during movement and causing inaccurate positioning. In summary, during use, the main shaft and the bearing can be synchronously positioned to ensure the coincidence of their central axes, avoiding the failure of press-fitting or damage to the main shaft and bearings due to position deviation during press-fitting.

[0032] After firmly clamping the main shaft and the bearing, the lifting rod 210 drives the second clamping plate 212 to descend. During this process, the cleaning motor 21 is started. The cleaning motor 21 can drive the driving gear 20 to rotate, so that the toothed ring 17 drives the linkage plate 18 to rotate on the base 11. When the linkage plate 18 moves, it can press the sliding seat 25 to slide along the slide rail 14 on the base 11, causing the sliding seat 25 to drive the cleaning plate 28 to approach the main shaft and stretch the return spring 27. When the toothed ring 17 rotates, the limiting block 16 can limit the linkage plate 18 through the limiting groove 19, preventing the linkage plate 18 and the toothed ring 17 from falling off the base 11 during rotation, and at the same time preventing the toothed ring 17 from shifting during rotation, resulting in the inability to drive the sliding seat 25 to move synchronously. The slide rail 14 can limit the sliding seat 25 to prevent the sliding seat 25 from deflecting during movement;

[0033] After the cleaning plate 28 presses one side of the brush plate 33 against the outer wall of the main shaft, the cleaning motor 21 stops running. The lifting rod 210 drives the second clamping plate 212 to continue descending, so that the bearing sleeve is outside the cleaning plate 28, and the brush plate 33 on the other side of the cleaning plate 28 fits on the inner ring of the bearing. Then the cleaning motor 21 drives the driving gear 20 to rotate forward again, causing the toothed ring 17 to drive the linkage plate 18 to move again. At this time, since the cleaning plate 28 has been pressed against the main shaft, the slide seat 25 cannot continue to move within the slide rail 14. At this time, all the components on the toothed ring 17 are indirectly integrated as a whole, enabling the toothed ring 17 to drive the base 11 to rotate on the bracket 8 through the slide seat 25, so that the cleaning plate 28 can clean and lubricate the pressing area of the main shaft and the bearing. In summary, during use, the cleaning plate 28 can be made close to the main shaft and the bearing, and the rotation of the base 11 drives the cleaning plate 28 to move, thereby cleaning and lubricating the main shaft and the bearing.

[0034] Please refer to Figure 1 and Figures 4 to 8 On the surface of the base 11, water tanks 22 are symmetrically and fixedly connected. One side of the water tank 22 is connected to a water pump 23, and one side of the water pump 23 is connected to a water supply pipe 24. A slide seat 25 is engaged and slidably connected within the slide rail 14. A through groove 26 is provided in the middle of the slide seat 25. One side of the slide seat 25 is connected to a return spring 27, and the slide seat 25 is elastically connected to the base 11 through the return spring 27. The slide seat 25 is slidably connected to the through oil pipe 15 through the through groove 26. One side of the slide seat 25 is connected to a cleaning plate 28. An oil chamber 29 is provided on one side of the cleaning plate 28. A cleaning chamber 30 is provided on the other side of the cleaning plate 28. One side of the cleaning chamber 30 is connected to a sleeve 31. Spray nozzles 32 are provided on both sides of the cleaning plate 28. Brush plates 33 are connected to both sides of the cleaning plate 28. The oil chamber 29 communicates with the through groove 26, and the cleaning chamber 30 communicates with the water supply pipe 24 through the sleeve 31;

[0035] The specific operations are as follows. During cleaning, an external oil pump pumps oil into the oil cavity 10 through a pipeline. The oil in the oil cavity 10 enters the annular groove 9 due to the fluidity of the oil, which can provide lubrication for the rotation of the base 11 and make its rotation smooth. At the same time, the water pump 23 can send the cleaning liquid from the water supply pipe 24 into the cleaning plate 28 through the sleeve 31, and then spray it from the nozzle 32 onto the main shaft and bearings in the cleaning chamber 30. As the toothed ring 17 drives the base 11 to rotate, the brush plate 33 can clean the pressing area of the main shaft and bearings. After cleaning is completed, the water pump 23 stops operating. At the same time, by continuously sending oil into the oil cavity 10, the oil in the oil cavity 10 can overflow and enter the oil groove 13 through the through hole 12, then enter the oil chamber 29 through the through oil pipe 15 and the through groove 26, and finally be sprayed onto the main shaft and bearings through the nozzle 32 to lubricate the pressing area, avoiding scratches on the main shaft and bearings caused by excessive friction or impurities on the surface during pressing. The through groove 26 and the sleeve 31 can not only maintain the connection between the cleaning plate 28 and the through oil pipe 15 and the water supply pipe 24 before and after the sliding seat 25 moves, but also restrict the sliding seat 25 through the through oil pipe 15 and the water supply pipe 24 to further prevent the sliding seat 25 from deflecting during movement;

[0036] After cleaning and lubrication are completed, the lifting rod 210 first drives the second clamping plate 212 to rise to disengage the bearing from the cleaning plate 28, and then the cleaning motor 21 drives the toothed ring 17 to reset through the driving gear 20. The sliding seat 25 can drive the cleaning plate 28 to reset under the action of the return spring 27. Then the lifting rod 210 drives the second clamping plate 212 to descend again, making the main shaft contact the bearing. Then the pressing rod 6 drives the pressing plate 7 to descend, and the bearing can be pressed onto the main shaft through the pressing plate 7. During pressing, the telescopic rod 3 can drive the material placing plate 4 to rise and fall, thereby adjusting the height of the upper end of the main shaft, and further adjusting the moving distance of the pressing plate 7 to avoid excessive movement of the pressing plate 7 causing pressure damage to the main shaft and bearings. In summary, during use, the main shaft and bearings can be cleaned and lubricated synchronously, ensuring the smooth progress of the pressing process and avoiding scratches on the main shaft and bearings during pressing due to impurities on the surface.
