Description

Technical Field

[0001] The utility model relates to the technical field of bearing polishing, and more particularly to a bearing polishing device. Background Art

[0002] A bearing is a mechanical component used to support a rotating shaft and reduce friction. It typically consists of an inner ring, an outer ring, rolling elements, and a cage. The inner and outer rings are mounted on the shaft and housing, respectively, with the rolling elements rolling between them, reducing friction between the shaft and housing. The cage maintains the rolling elements in position and prevents them from colliding. The primary function of a bearing is to support the rotating shaft, enabling smooth rotation while reducing friction and wear. It is widely used in various mechanical equipment, such as automobiles, aircraft, ships, machine tools, and electric motors. Depending on the application requirements, bearings can be divided into various types, such as deep groove ball bearings, tapered roller bearings, spherical roller bearings, and thrust ball bearings. Each type of bearing has its own specific structural and performance characteristics, suitable for different operating conditions and load requirements.

The utility model, by designing structures such as the connecting block and the inner support plate, gradually extends the inner support column embedded in the slide groove provided on the surface of the connecting block until the surface of the inner support plate is tightly fitted on the inner wall of the bearing ring. The servo motor is started to drive the rotating wheel to rotate, and the outer and inner rings of the bearing ring are polished and polished simultaneously. The design of the connecting block and the inner support plate prevents the bearing ring from being accidentally damaged by manual hand-held contact with the rotating wheel.

[0024] When workers polish the bearing rings, they are unable to polish the inner and outer walls of the bearings at the same time, which increases the equipment cost of the bearing polishing and the production processing time of the bearings, and reduces the work efficiency of bearing production.

[0025] Based on this, in order to improve the problem in the related art that the inner and outer walls of the bearing cannot be polished simultaneously.

[0031] With such arrangement, when the staff needs to polish the bearing ring 7, the staff fixes the bearing ring 7 on the fixed frame, and then rotates the second servo motor 2142, the bidirectional screw rod 2144 is rotated and connected to the frame 1, and is connected to the second servo motor 2142, the bidirectional screw rod 2144 rotates accordingly, and the first slider 2145 sleeved on the bidirectional screw rod 2144 will rotate with the rotation of the bidirectional screw rod 2144. At this time, the first support seat 213 connected to the top of the first slider 2145 will also be displaced with the movement of the first slider 2145, and the first servo motor 212 set on the first support seat 213 and the first polishing wheel 211 connected to the first servo motor 212 will also move accordingly. The staff adjusts the position of the first slider 2145 on the screw rod 36 so that the first polishing wheel 211 contacts the outer wall of the bearing ring 7, and then the staff moves the second slider 221 to move the telescopic rod 223 toward the direction of the bearing ring 7, just to move the connecting rod The second polishing wheel 225 on 224 extends into the interior of the bearing ring 7, and then the staff adjusts the position of the telescopic rod 223 to make the second polishing wheel 225 contact the inner wall of the bearing ring 7. After completing the preparations before polishing, the first servo motor 212, the third servo motor 226 and the reduction motor 38 are started. The reduction motor 38 rotates to drive the pressure shaft 32 to rotate, and the pressure shaft 32 pushes the bearing to rotate. At the same time, the first servo motor 212 and the third servo motor 226 respectively drive the first polishing wheel 211 and the second polishing wheel 225 to rotate at high speed at the same time. While the bearing itself rotates, the first polishing wheel 211 and the second polishing wheel 225 synchronously polish the inner and outer walls of the bearing to ensure the consistency of the polishing effect of the inner and outer walls, and the polishing efficiency is high and the practicality is good. The consistency of the polishing effect of the inner and outer walls of the bearing is ensured, the polishing operation of the inner and outer walls of the bearing is avoided separately, the work efficiency is improved, and the polishing cost of the bearing is reduced, the operability of the polishing is reduced, and the production and processing time of the bearing is reduced.

[0032] Working principle: When the staff uses the polishing device, they first need to place the bearing ring 7 on the fixed frame, make the outer peripheral surface of the bearing ring 7 abut against the rotating shaft 8 on the fixed frame, and then start the drive motor 33. The drive motor 33 drives the first bevel gear 34 to rotate. Because the first bevel gear 34 is meshed with the second bevel gear 35, the second speed wheel also rotates. As the second bevel gear 35 rotates, the screw rod 36 also rotates. The third slider 37 mounted on the screw rod 36 will move up and down on the screw rod 36 as the screw rod 36 rotates, and is fixedly connected to the third slider 37. The connected pressing shaft 32 can move up and down on the through hole. The staff can adjust the position of the pressing shaft 32 on the second through hole 5 according to the different sizes of the bearing rings 7, and perform the operation of pressing and fixing the bearing ring 7. Then, the second servo motor 2142 rotates, and the bidirectional screw rod 2144 is rotated and connected to the frame 1, and is connected to the second servo motor 2142. The bidirectional screw rod 2144 rotates accordingly, and the first slider 2145 sleeved on the bidirectional screw rod 2144 will rotate with the rotation of the bidirectional screw rod 2144. At this time, the first support seat 213 connected to the top of the first slider 2145 is rotated. , will also be displaced with the movement of the first slider 2145, and the first servo motor 212 set on the first support seat 213 and the first polishing wheel 211 connected to the first servo motor 212 will also move. The staff adjusts the position of the first slider 2145 on the screw rod 36 so that the first polishing wheel 211 contacts the outer wall of the bearing ring 7. Then the staff moves the second slider 221 and moves the telescopic rod 223 toward the direction of the bearing ring 7, just extending the second polishing wheel 225 on the connecting rod 224 into the interior of the bearing ring 7. Then the staff adjusts the telescopic rod 223 to move the second polishing wheel 225 into the interior of the bearing ring 7. The position of the retracted rod 223 makes the second polishing wheel 225 contact the inner wall of the bearing ring 7. After completing the preparation work before polishing, the first servo motor 212, the third servo motor 226 and the reduction motor 38 are started. The reduction motor 38 rotates to drive the pressing shaft 32 to rotate, and the pressing shaft 32 pushes the bearing to rotate. At the same time, the first servo motor 212 and the third servo motor 226 respectively drive the first polishing wheel 211 and the second polishing wheel 225 to rotate at high speed at the same time. While the bearing itself rotates, the first polishing wheel 211 and the second polishing wheel 225 synchronously polish the inner and outer walls of the bearing.
