[0001] The utility model relates to the outer diameter processing technology of thin-wall bearing rings, in particular to an outer diameter precision lapping machine. Background Art
[0002] Grinding is usually the last process in the processing of bearing rings, and the dimensional accuracy of the rings is ensured through this process. However, the surface roughness of the ground bearing rings is unstable, affecting subsequent assembly and the service life of the bearings. Due to the characteristics of thin-wall bearings, they are prone to deformation during the processing. Ordinary precision lapping equipment generally uses a cylinder to control the oilstone to process the shape of the product. During this process, the air pressure cannot be controlled, which will increase the deformation of the thin-wall bearing rings. As an important assembly part, the outer diameter of the bearing rings needs to strictly control its size, accuracy and surface roughness. Therefore, the defects in ordinary equipment and process technology cannot meet the processing requirements of the outer diameter of such bearing rings. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide an outer diameter precision lapping machine that can effectively control the processing deformation.
[0004] The technical solution adopted by the utility model to solve its technical problem is: the outer diameter precision lapping machine includes a base for connecting with a frame, an oilstone adjusting mechanism arranged on the base, and an oilstone clamping mechanism arranged below the oilstone adjusting mechanism;
[0005] The oilstone adjusting mechanism includes an oilstone pressure block connected to the base, a pin shaft slidably arranged on the oilstone pressure block, and an elastic member cooperating with the pin shaft for applying pressure in the direction towards the pin shaft;

[0010] Further, it further includes an L-shaped connecting member, a waist-shaped hole is arranged on the L-shaped connecting member, and a connecting member is passed through the waist-shaped hole to connect the oilstone pressure block and the web.
[0011] Further, a slideway is opened inside the oilstone pressure block, the pin shaft is arranged in the slideway, and the elastic member is arranged in the slideway and presses against the upper end of the pin shaft.

Detailed implementation manner
[0025] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific implementation manner of the present utility model will now be described in detail with reference to the accompanying drawings.
[0026] As Figures 1-6 shown in the outer diameter precision grinding machine, it includes a base 1 for connecting with the machine frame, an oilstone adjustment mechanism arranged on the base 1, and an oilstone clamping mechanism arranged below the oilstone adjustment mechanism;
[0027] The oilstone adjustment mechanism includes an oilstone pressure block 2 connected to the base 1, a pin shaft 3 slidably arranged on the oilstone pressure block 2, and an elastic member 4 cooperating with the pin shaft 3 for applying pressure in the direction towards the pin shaft 3;
[0028] The oilstone clamping mechanism includes a clamping member 5 connected to the lower end of the pin shaft 3.
[0029] This outer diameter precision grinding machine includes an oilstone adjustment mechanism and an oilstone clamping mechanism. When processing a workpiece, in the oilstone adjustment mechanism, the oilstone pressure block 2 part has an upward force using the pin shaft 3. At this time, the elastic member 4 will deform, which can effectively ensure that the surface pressure value of the workpiece is within a controllable range and greatly reduce the deformation amount of the workpiece. In addition, the oilstone clamping mechanism part can adjust the number of oilstones 100 according to the size of the workpiece and is applicable to different oilstone 100 specifications. It does not affect the processing efficiency after clamping and has a wider application range.
[0030] The oilstone clamping mechanism further includes an oilstone support block 52 for clamping the oilstone. In this embodiment, the clamping member 5 includes a web connected to the lower end of the pin shaft 3 and wing plates connected to both sides of the web, and the oilstone support block 52 is connected to the web.
[0031] Preferably, an adjustment chute 51 is provided on the web, and the oilstone support block 52 is slidably limited within the adjustment chute 51 and the position of the oilstone support block 52 is adjusted by an adjustment bolt 53.
[0032] By using the adjustable oilstone support block 52, when clamping different specifications or quantities of oilstones, the position of the oilstone support block 52 is adjusted by sliding and the clamping adjustment is realized by using the adjustment bolt 53. It is convenient to use, has a simple structure, and at the same time has better applicability and can meet the grinding requirements of different oilstone precisions.
[0033] To achieve stable connection, it further includes an L-shaped connecting piece 6. The L-shaped connecting piece 6 is provided with a waist-shaped hole, and a connecting piece is passed through the waist-shaped hole to connect the oilstone pressure block 2 with the web. In this embodiment, the connecting piece is a screw, and the screw is passed through the waist-shaped hole. When a force is provided to the workpiece during processing with the waist-shaped hole design, by using the upward force of the pin shaft 3, the elastic member 4 will deform at this time, which can effectively ensure that the surface pressure value of the workpiece is within a controllable range and greatly reduce the deformation amount of the workpiece.
[0034] Specifically, a slideway is opened inside the oilstone pressure block 2, the pin shaft 3 is arranged in the slideway, and the elastic member 4 is arranged in the slideway and presses against the upper end of the pin shaft 3. In this embodiment, the elastic member 4 is a spring. The present utility model is designed by combining a common precision lapping device and according to the characteristics of thin-walled bearings, and uses the self-weight of the structure and the telescoping of the spring to apply pressure, so as to finely lap the outer diameter of the bearing, thereby reducing the deformation amount during the fine lapping process of such products and improving the dimensional accuracy and surface roughness of the bearing ring.
[0035] In this embodiment, part of the base 1 is not directly connected to the machine tool. According to the size of the workpiece to be processed, it can be connected to other components during the processing to realize up, down, front and back movement and use its own weight to provide pressure for the precision lapping process. Preferably, it further includes a front and back adjustment mechanism 7. The front and back adjustment mechanism 7 includes lower connecting pieces 71 arranged on both sides of the lower part of the base 1, front and back adjustment blocks 72 arranged at the rear side of the lower connecting pieces 71, a first screw rod 73 connecting the lower connecting pieces 71 and the front and back adjustment blocks 72, and a first adjustment handwheel 74 connected to the front end of the first screw rod 73.
[0036] It further includes an up and down adjustment mechanism 8. The up and down adjustment mechanism 8 includes upper connecting pieces 81 arranged on both sides of the upper part of the base 1, up and down adjustment blocks 82 arranged on the upper connecting pieces 81, a second screw rod 83 connecting the up and down adjustment blocks 82, and a second adjustment handwheel 84 connected to the upper end of the second screw rod 83.
[0037] It further includes a support guide roller 9 arranged below the oilstone clamping mechanism. When the support guide roller 9 drives the product to move, the oilstone contacts the outer diameter of the product, the oilstone clamp rises, thereby driving the pin shaft to rise, and the spring in the oilstone pressure block 2 contracts, and the precision lapping of the outer diameter of the bearing is realized by using mechanical swing.
