Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing processing technology, specifically a polishing and grinding device for bearing production. Background Technology
[0002] Bearings are essential components in modern machinery. Their primary function is to support rotating mechanical parts, reduce the coefficient of friction during movement, and ensure rotational accuracy. Based on the frictional properties of the moving elements, bearings can be broadly classified into rolling bearings and sliding bearings. In the manufacturing process of mounted bearings, to ensure smooth operation and longevity, the inner ring often requires grinding. This grinding is typically completed before the bearing is assembled with its housing. This ensures that the dimensions, surface finish, and geometry of the bearing inner ring meet requirements, providing optimal bearing performance.
[0003] Current grinding equipment typically uses a single grinding disc to grind bearings. This method results in a small contact area between the grinding disc and the bearing, leading to low grinding efficiency.
[0004] Therefore, we propose a polishing and grinding device for bearing production to solve the problems mentioned above. Utility Model Content
[0005] The purpose of this utility model is to solve the aforementioned technical problems.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a polishing and grinding device for bearing production, comprising a base, on which a bearing mounting seat and a column are mounted. The bearing mounting seat has an inwardly recessed placement groove on its top. A first motor is mounted on the top of the column, and the output shaft of the first motor extends into the interior of the column to mount a lead screw. A lifting bracket is threaded onto the lead screw, and one end of the lifting bracket extends into the exterior of the column to mount a grinding cover. Several grinding shafts for grinding bearings are rotatably mounted at equal intervals on the grinding cover. A second motor is also mounted at the center of the grinding cover, and the output shaft of the second motor is connected to the several grinding shafts through a transmission assembly.
[0007] Furthermore, the two ends of the grinding shaft are rotatably mounted on the support seats, and the two support seats are fixed on the outer surface of the grinding cover.
[0008] Furthermore, the transmission assembly includes a drive gear mounted on the output shaft of the second motor and driven gears respectively mounted on the ends of the grinding shaft, and the drive gear and several driven gears mesh with each other.
[0009] Furthermore: First rotating seats are symmetrically installed on both sides of the bearing mounting base, and the same wrench is rotatably installed between every two first rotating seats. A second rotating seat is fixed on the outer surface of the wrench, and an "L"-shaped fastening rod is rotatably installed on the second rotating seat. The two fastening rods are connected by a connecting assembly.
[0010] Furthermore, the connecting assembly includes a hook rotatably mounted on the end of one of the fastening rods and a slot formed at the end of the other fastening rod.
[0011] The beneficial effects of this utility model are:
[0012] This invention features a grinding shaft rotatably mounted on a grinding cover. Through the cooperation of a second motor and a transmission assembly, the grinding shafts can be driven to rotate at high speed and simultaneously grind the outer surface of the bearing, thereby increasing the grinding area and improving the efficiency of bearing grinding.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0020] A polishing and grinding device for bearing production includes a base 1, a bearing support 2 fixed on the top of the base 1, and an inwardly recessed placement groove (not shown in the figure) on the top of the bearing support 2. The placement groove serves to store the bearing and facilitates subsequent cutting and grinding.
[0021] The bearing support 2 is symmetrically fixed with first rotating seats 12 on both sides. A wrench 13 is rotatably installed between every two first rotating seats 12. A second rotating seat 14 is fixed on the outer surface of the wrench 13. An "L"-shaped fastening rod 15 is rotatably installed on the second rotating seat 14. The two fastening rods 15 are connected by a connecting assembly 16. The arrangement of the first rotating seats 12, wrench 13, second rotating seats 14 and fastening rods 15 serves to fasten the bearing and prevent the bearing from shaking during the grinding process.
[0022] In detail: The connecting assembly 16 includes a hook 1601 rotatably mounted on the end of one of the fastening rods 15, and a hanging groove 1602 is provided on the other fastening rod 15. The hook 1601 and the hanging groove 1602 serve to fasten the two fastening rods 15.
[0023] A column 3 is vertically fixed to the top of the base 1, and a first motor 4, which is a servo motor, is installed on the top of the column 3. The output shaft of the first motor 4 extends into the interior of the column 3 and a lead screw 5 is installed thereon. A lifting bracket 6 is threaded onto the lead screw 5, and a grinding cover 7 is installed on one end of the lifting bracket 6 extending to the outside of the column 3. Several grinding shafts 8 are equidistantly installed on the grinding cover 7 along the circumferential direction. The grinding shafts 8 are used to grind the bearings. It should be noted that support seats 11 are rotatably installed at both ends of the grinding shafts 8, and the support seats 11 are fixed to the outer surface of the grinding cover 7. The support seats 11 support the grinding shafts 8. A second motor 9 is installed at the center of the grinding cover 7, and the output end of the second motor 9 is connected to several grinding shafts 8 through a transmission assembly 10, thereby driving several grinding shafts 8 to rotate simultaneously.
[0024] When grinding the bearing, first place the bearing inside the placement slot, then fit the hook 1601 onto the hanging slot 1602, and simultaneously pull the two wrenches 13 downwards. The wrenches 13, through the second rotating seat 14, can drive the fastening rod 15 downwards, and the two fastening rods 15 can fasten the bearing. Then, turn on the first motor 4. The first motor 4 drives the lifting bracket 6 downwards through the lead screw 5. The lifting bracket 6 drives the grinding cover 7 downwards, so that the several grinding shafts 8 on the grinding cover 6 come into contact with the outer surface of the bearing. Finally, turn on the second motor 9. The output shaft of the second motor 9 can drive the drive gear 101 to rotate. The drive gear 101 drives the grinding shafts 8 to rotate through several driven gears 102, and the several grinding shafts 8 can grind the outer surface of the bearing.
