Description

Technical Field

[0001] This application relates to the technical field of bearing washer processing. Specifically, it relates to an outer circle grinding fixture for bearing washers. Background Art

[0002] Bearing washers are mechanical parts mainly used in bearing systems. Bearing washers are located between bearing elements, which can effectively reduce friction and wear and extend the service life of bearings. They are used to support and position bearing elements, ensuring the correct position and clearance between the inner and outer rings of the bearing and between the rolling elements and the inner and outer rings to maintain the running stability of the bearing. Bearing washers can absorb and disperse axial and radial loads, avoiding damage to the bearing and surrounding structures caused by concentrated stress. Bearing washers are usually made of high-strength metal materials such as steel, copper alloy or aluminum alloy, with good wear resistance and fatigue resistance. Their manufacturing processes usually include cold drawing, cold rolling, cutting or stamping to ensure their accuracy and surface quality. Bearing washers are widely used in various industrial and mechanical equipment, such as automobiles, aerospace, power equipment, heavy machinery, etc. They play an important supporting and protecting role in these fields, ensuring the reliable operation of mechanical systems. The design of bearing washers must consider the specific bearing type and application requirements to ensure good fit with the bearing and provide the required supporting and protecting functions under expected working conditions.

Specific embodiments

[0021] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0022] Refer to Figures 1 - 4 , the present application provides a technical solution: an outer circle grinding fixture for a bearing washer, including a clamping head 1 and a clamping mechanism 2. The clamping head 1 is used for clamping the bearing washer, and there are four clamping heads 1; the clamping mechanism 2 is located between the four clamping heads 1, and it includes a cross 201 and an extension rod 202. The clamping mechanism 2 can make the clamping head 1 approach the inner ring of the bearing washer for clamping. The extension rod 202 is slidably connected to the cross 201. The clamping head 1 is arranged on the outside of the extension rod 202. The extension rod 202 can be controlled to slide relative to the cross 201. The outside of the clamping head 1 is set as an arc surface. The four clamping heads 1 are arranged at equal intervals in a ring. Anti-slip protrusions 210 are arranged on the arc surface of the clamping head 1. By setting the outside of the clamping head 1 as an arc surface, the clamping head 1 fits better with the inner ring of the bearing washer, and the anti-slip protrusions 210 can enhance the clamping stability;

[0023] A cylinder 203 is fixedly connected to the bottom of the cross 201. A toothed plate 204 is fixedly connected to the telescopic end of the cylinder 203. The cross 201 is rotatably connected to a rotating shaft 205. A gear 206 is fixedly connected to the outer wall of the rotating shaft 205. The gear 206 is meshed with the toothed plate 204. A turntable 207 is fixedly connected to the top of the rotating shaft 205. A sliding groove 208 is formed in the top of the turntable 207. A connecting rod 209 is fixedly connected to the top of the extension rod 202. The connecting rod 209 is slidably connected to the inner wall of the sliding groove 208. By starting the cylinder 203, the telescopic end of the cylinder 203 drives the toothed plate 204 to move. The toothed plate 204 drives the gear 206 to rotate. The gear 206 drives the rotating shaft 205 to rotate. The rotating shaft 205 drives the turntable 207 to rotate. The rotation of the turntable 207 drives the connecting rod 209 to slide outwards. The connecting rod 209 drives the extension rod 202 to slide outwards along the cross 201, so as to drive the clamping head 1 to closely adhere to the inner ring of the bearing washer for clamping and fixing. The fixing effect is good, the processing quality is improved, and by fixing the inner ring of the bearing washer, the outer circle of the bearing washer is completely exposed, which is more convenient for grinding processing;

[0024] Mounting pieces 4 are fixedly connected to the bottom of the cross 201. There are several mounting pieces 4. Threaded holes are formed in each of the several mounting pieces 4. The mounting pieces 4 are used to fix the whole fixture on the workbench surface;

[0025] A disassembly mechanism 3 is arranged between the clamping head 1 and the extension rod 202. The disassembly mechanism 3 includes a fixing block 301. The fixing block 301 is fixedly connected to the side of the clamping head 1 close to the extension rod 202. A limiting groove 302 is formed on the outer side of the fixing block 301. A fixing groove 303 is formed on the side of the extension rod 202 close to the fixing block 301. The fixing block 301 is inserted into the inner wall of the fixing groove 303. A threaded rod 304 is threadedly connected to the extension rod 202. A knob 305 is fixedly connected to the outer side of the threaded rod 304. The threaded rod 304 is rotatably connected to a limiting block 306 through a bearing. The limiting block 306 is inserted into the inner wall of the limiting groove 302. A sliding groove 307 is formed in the extension rod 202. The limiting block 306 is slidably connected to the inner wall of the sliding groove 307. By rotating the knob 305, the knob 305 drives the threaded rod 304 to rotate. The threaded rod 304 drives the limiting block 306 to slide into the sliding groove 307 until the limiting block 306 is removed from the limiting groove 202, and then the clamping head 1 can be pulled outwards to remove the fixing block 301 from the fixing groove 303 of the extension rod 202. When the clamping head 1 is worn or cannot be used continuously, it can be disassembled and replaced to ensure the clamping stability. At the same time, it can also avoid the situation that the whole fixture is scrapped when one clamping head 1 cannot be used, reducing the use cost.
