Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to a bearing grinding device for bearing processing. Background Technology

[0002] In the bearing processing field, grinding is a crucial step in ensuring bearing precision and surface quality. The structural design of bearing grinding equipment directly affects processing efficiency, product qualification rate, and equipment operating costs. Currently, mainstream bearing grinding equipment on the market typically adopts a fixed chuck and a moving grinding head operation mode. Its core workflow is as follows: the bearing to be processed is placed on the chuck, and the bearing is positioned and fixed by the chuck's own clamping components (such as pneumatic chucks, hydraulic chucks, etc.). Then, the grinding head is controlled to move vertically downwards until it contacts the bearing surface to be ground and completes the grinding process. However, when it is necessary to grind the side of the bearing, because the bearing is in close contact with the chuck surface, the grinding head is very likely to come into contact with and collide with the chuck as it approaches the side of the bearing. This not only damages the chuck and affects its service life, but also leads to accelerated wear of the grinding head, and may even cause damage to the grinding head. This, in turn, affects the precision and continuity of the entire grinding operation, increasing production and maintenance costs.

[0003] To address the aforementioned issues, some existing technologies attempt to employ additional drive components to enable the bearing to slide, allowing it to leave the chuck surface during grinding head descent, thus creating conditions for side grinding. However, this approach significantly increases the overall structural complexity of the device, requiring the introduction of new power sources and control circuits. This not only increases the difficulty of manufacturing and installing the equipment but also makes maintenance and debugging more cumbersome, reduces the stability and reliability of the equipment, and increases its energy consumption.

[0004] Therefore, it is necessary to provide a bearing grinding apparatus for bearing processing to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a bearing grinding device for bearing processing, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a bearing grinding device for bearing processing, including: a clamping table, and further including: a drive assembly disposed inside the clamping table; The lifting plate has a clamping rod slidably connected to the top, and the clamping rod can converge or disperse towards the axis of the clamping platform under the drive of the drive component to clamp the outer or inner ring of the bearing. A transmission component is also provided on the outside of the lifting plate. The cylinder has a mounting plate and a connecting rod fixedly installed at its telescopic end, and a grinding assembly is installed at the bottom of the mounting plate. When the cylinder pushes the grinding assembly and connecting rod to descend or rise, the connecting rod can raise or lower the lifting plate and clamping rod through the transmission assembly, thereby driving the bearing to leave the surface of the clamping table for grinding.

[0007] Preferably, the top of the clamping platform has multiple clamping grooves radially provided, the clamping rod is slidably connected in the clamping grooves, the side of the clamping platform has multiple lifting grooves axially provided, the bottom of the clamping platform is fixedly connected to multiple support legs, and the transmission component is located above the support legs. The side of the lifting plate is also fixedly connected to multiple guide frames.

[0008] Preferably, the drive assembly includes: a motor and a gear 1. The motor is fixedly mounted on the top inner wall of the frame, and the gear 1 is fixedly connected to the drive end of the motor. A gear ring is rotatably mounted on the top inner wall of the clamping platform, and the gear 1 meshes with the gear ring.

[0009] Preferably, a gear frame is fixedly connected inside the clamping platform, and a second gear is rotatably connected to the gear frame. The second gear meshes with a gear ring, and a lead screw is threaded to the inner side of the second gear. The lead screw passes through the side wall of the clamping platform, and a sleeve is fixedly connected to the end of the lead screw near the central axis of the clamping platform. The clamping rod is sleeved inside the sleeve.

[0010] Preferably, the lifting plate has multiple lifting bars fixedly connected to its side, and the lifting bars are slidably connected inside the lifting groove. Multiple lifting guide rods are fixedly connected to the bottom of the lifting bars, and the clamping rods are slidably connected to the top of the lifting plate.

[0011] Preferably, the transmission assembly includes: a first cavity column and a second cavity column, both of which are fixedly connected to the top of the support leg and are connected to each other. A lifting guide rod is slidably connected inside the first cavity column, and a piston is provided between the lifting guide rod and the inner wall of the first cavity column. A piston disc is provided inside the second cavity column, and the second cavity column is thinner at the top and thicker at the bottom.

[0012] Preferably, the grinding assembly is mounted on a mounting plate. The grinding assembly includes a fixed seat, a rotating seat, and a grinding head. The fixed seat is mounted on the mounting plate, the rotating seat is rotatably mounted inside the fixed seat, and the grinding head is disposed on the rotating seat.

[0013] Compared with related technologies, the bearing grinding device for bearing processing provided by this utility model has the following beneficial effects: 1. When the grinding head moves down to perform the grinding task, this bearing grinding device can drive the bearing to move up synchronously through the transmission component, so that the bearing can quickly disengage from the chuck surface. This avoids the problem of the bearing being too close to the chuck, which would cause the side of the grinding head to collide with the chuck during grinding. It can effectively avoid scratches, deformation and other damage to the chuck caused by collision, and extend the service life of the chuck. At the same time, it can prevent wear and cracking of the grinding head caused by contact with the chuck, reduce the frequency of grinding head replacement, significantly reduce equipment maintenance costs and production consumable costs, and ensure the continuous and stable operation of grinding work.

[0014] Second, because the upper movement of the bearing and the lower movement of the grinding head are linked through a transmission assembly, they form a precise synchronous relationship. No manual operation or additional control system is required for coordination. This ensures that the bearing has smoothly disengaged from the chuck surface when the grinding head reaches the grinding position, providing ample operating space for side grinding and avoiding grinding delays or positional deviations caused by asynchronous movements. Simultaneously, it eliminates the time required for starting and adjusting additional drive components in traditional devices, shortening the single grinding cycle and improving bearing processing efficiency.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figures 1 to 5A bearing grinding device for bearing processing includes: a clamping table 10, a gear ring 20, a drive assembly 21, a clamping assembly 30, a lifting plate 40, a transmission assembly 41, a cylinder 50, a grinding assembly 52, and a connecting rod 53. The gear ring 20 is rotatably mounted inside the clamping table 10. The drive assembly 21 is located inside the clamping table 10 and can drive the gear ring 20 to rotate, thereby moving the clamping assembly 30. Multiple clamping assemblies 30 are provided and located inside the clamping table, below the gear ring 20. The lifting plate 40 is located inside the clamping table 10 and below the clamping assembly 30, and is provided with... Multiple transmission components 41 and cylinder 50 are mounted above the clamping platform 10. Cylinder 50 can be fixed by a mounting bracket (not shown in the figure). Grinding chip processing components can also be installed on the mounting bracket to process grinding chips. Grinding component 52 and connecting rod 53 are fixedly connected to the telescopic end of cylinder 50. Drive component 21 drives gear ring 20 to rotate so as to drive clamping component 30 to fix the outer ring or inner ring of the bearing. When cylinder 50 pushes grinding component 52 and connecting rod 53 to move down to grind the bearing, the lifting plate 40 can be raised through transmission component 41, thereby raising the bearing to a certain height.

[0019] The top of the clamping platform 10 has multiple clamping grooves 101 radially provided, and the clamping assembly 30 can slide along the clamping grooves 101. The side of the clamping platform 10 has multiple lifting grooves 102 axially provided, and the lifting plate 40 can slide along the lifting grooves 102. The bottom of the clamping platform 10 is fixedly connected to multiple support legs 11, and the transmission assembly 41 is located above the support legs 11. The side of the lifting plate 40 is also fixedly connected to multiple guide frames 12 to limit the sliding path of the connecting rod 53.

[0020] The drive assembly 21 includes a motor 211 and a gear 212. The motor 211 is fixedly installed on the top inner wall of the frame, and the gear 212 is fixedly connected to the drive end of the motor 211. The gear 212 meshes with the gear ring 20. When the motor 211 drives the gear 212 to rotate, it can drive the gear ring 20 to rotate through meshing.

[0021] The clamping assembly 30 includes: a second gear 301, a lead screw 302, a sleeve 303, and a clamping rod 304. A gear frame 3011 is rotatably connected to the second gear 301, and the gear frame 3011 is fixedly connected to the inner wall of the frame. The second gear 301 meshes with the gear ring 20. The lead screw 302 is located inside the clamping platform 10 and below the clamping groove 101, and the lead screw 302 passes through the side wall of the clamping platform 10. The lead screw 302 is threadedly connected to the inner wall of the second gear 301, and the sleeve 303 is fixedly connected to the end of the lead screw 302 near the central axis of the clamping platform 10. The clamping rod 304 is sleeved inside the sleeve 303. When the gear ring 20 rotates, the second gear 301 rotates through meshing. The second gear 301 slides along the clamping groove 101 through the threaded connection with the lead screw 302.

[0022] Multiple lifting bars 401 are fixedly connected to the side of the lifting plate 40, and the lifting bars 401 are slidably connected inside the lifting groove 102. Multiple lifting guide rods 4011 are fixedly connected to the bottom of the lifting bars 401. The clamping rod 304 is slidably connected to the top of the lifting plate 40. When the lifting plate 40 rises and falls, the clamping rod 304 is pushed and slides in the sleeve 303 to follow the rise and fall of the lifting plate 40.

[0023] The transmission assembly 41 includes a first cavity column 411 and a second cavity column 412. Both the first cavity column 411 and the second cavity column 412 are fixedly connected to the top of the support leg 11 and are connected to each other. The lifting guide rod 4011 is slidably connected inside the first cavity column 411. A piston is provided between the lifting guide rod and the inner wall of the first cavity column 411. The second cavity column 412 has a piston disc 4121 inside. The second cavity column 412 is thinner at the top and thicker at the bottom. When the piston disc 4121 slides up and down inside the cavity column, the gas inside the second cavity column 412 and the first cavity column 411 flows back and forth, causing the lifting guide rod to move up and down, thereby pushing the lifting plate 40 to slide up and down inside the clamping platform 10.

[0024] Mounting plate 51 is rectangular. Grinding assembly 52 can be installed at different positions on mounting plate 51 according to the diameter of bearing. Grinding assembly 52 includes: fixed seat 521, rotating seat 522 and grinding head 523. Rotating seat 522 is rotatably mounted inside fixed seat 521. A driving component (not shown in the figure) is provided inside fixed seat 521, which can drive rotating seat 522 to rotate. Grinding head 523 is located at the bottom of rotating seat 522. A driving component (not shown in the figure) is provided inside rotating seat 522, which can push grinding head 523 to move radially along rotating seat 522. Grinding head 523 can rotate under the drive of driving component (not shown in the figure) to grind the surface of bearing. Grinding head 523 can move radially along rotating seat 522, and can slightly change the grinding position to grind the inner and outer rings of bearing.

[0025] When the telescopic end of cylinder 50 extends, mounting plate 51, grinding assembly 52 and connecting rod 53 move down synchronously. The bottom end of connecting rod 53 is slidably connected to the inside of the thin tube of cavity column 412, and a piston is provided between the contact surface between connecting rod 53 and the inside of cavity column 412. When grinding is performed and grinding is finished, when connecting rod 53 moves up and down with grinding assembly 52, it can push the piston plate inside cavity column 412 to move up and down in the thick tube. The gas volume between connecting rod 53 and piston plate remains unchanged. The gas below piston plate flows into cavity column 411 or the airflow below lifting guide rod 4011 flows into cavity column 412.

[0026] The working principle of the bearing grinding device for bearing processing provided by this utility model is as follows: After placing the bearing to be processed in the corresponding position on the clamping table 10, start the motor 211 in the drive assembly 21. The motor 211 drives the gear 212 to rotate. Since the gear 212 meshes with the gear ring 20, the gear ring 20 rotates synchronously with the gear 212. Then, through the meshing action, the gear 301 in the multiple clamping assemblies 30 is driven to rotate. The gear 301 is threadedly connected to the lead screw 302. When the gear 301 rotates, it will drive the lead screw 302 to move radially along the clamping groove 101. The sleeve 303 and clamping rod 304 at the end of the lead screw 302 slide synchronously. Finally, the inner ring or outer ring of the bearing is clamped and fixed from different directions by the multiple clamping rods 304. After clamping is completed, cylinder 50 is activated, and the telescopic end of cylinder 50 extends, pushing the mounting plate 51, grinding assembly 52, and connecting rod 53 to move downwards simultaneously. The bottom end of connecting rod 53 extends into cavity column 412. As connecting rod 53 moves downwards, piston disc 4121 in cavity column 412 is pushed downwards, compressing the gas below cavity column 412. Since cavity column 411 and cavity column 412 are connected, the gas flows into cavity column 411 through the connecting channel, pushing the piston and lifting guide rod 4011 in cavity column 411 upwards. The movement causes the lifting plate 40 to rise along the lifting groove 102, thereby lifting the clamping rod 304 and the bearing to a certain height (detaching them from the surface of the clamping table 10 to avoid the grinding head 523 colliding with the clamping table 10). At the same time, the grinding assembly 52 moves down with the mounting plate 51 to the bearing to be processed position. The driving component in the fixed seat 521 drives the rotating seat 522 to rotate. The driving component in the rotating seat 522 pushes the grinding head 523 to be finely adjusted radially to a suitable position. Finally, the side of the bearing is ground by the rotation of the grinding head 523. After grinding is completed, the cylinder 50 retracts, causing the mounting plate 51, grinding assembly 52 and connecting rod 53 to move upward. After the connecting rod 53 moves upward, the air pressure in the second cavity 412 decreases, and the gas in the first cavity 411 flows back to the second cavity 412. The lifting guide rod 4011 and the lifting plate 40 descend and reset under the action of gravity. The bearing is repositioned on the surface of the clamping table 10. The drive assembly 21 rotates in the opposite direction, causing the clamping rod 304 of the clamping assembly 30 to loosen, and the processed bearing can be taken out.
