Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to a grinding device for forging the outer ring of a bearing. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. Rolling bearings generally consist of four parts: an outer ring, an inner ring, rolling elements, and a cage. Strictly speaking, they consist of six major components: an outer ring, an inner ring, rolling elements, a cage, a seal, and lubricating oil. Grinding the outer ring is an essential step in the bearing manufacturing process.

[0003] Chinese Patent Application No. 201721668521.X discloses a grinding device for the outer ring of a bearing forging, including a grinding wheel and a fan. The bearing is mounted on a mounting component. A first motor and a second motor are turned on. The first motor drives the main shaft to rotate, and the rotation of gear two drives two gears one to rotate slowly, causing the bearing to rotate slowly. The second motor drives the grinding wheel to rotate at high speed, rotating the rotating block and causing the grinding wheel to contact the outer ring of the bearing, thus grinding the outer ring. Waste is generated during the grinding process. Turning on the fan allows the waste to be directly blown into a waste collection box. Through the compression of the compression plate and spring, the entire waste collection box can be easily installed and disassembled, providing convenience for waste removal. The fan blowing can reduce the friction temperature between the grinding wheel and the outer ring of the bearing, thus making the operation smoother. This utility model can collect the waste generated during grinding using fan blowing, facilitating waste removal and reducing the temperature during operation, thereby improving processing accuracy and efficiency.

[0004] However, the above-mentioned technical solution is inconvenient to disassemble because the rotating rod is installed inside the grinding box. When grinding a large number of bearing rings, the above solution will require the user to repeatedly install or remove the bearing rings. This will greatly increase the downtime of the grinding mechanism, thereby reducing the efficiency of grinding the bearing rings. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model, through the setting of a base, fixing mechanism, positioning mechanism, adjusting mechanism, and grinding mechanism, allows the user to place the bearing ring to be ground onto four arc-shaped plates, ensuring that one side of each bearing ring contacts the arc-shaped retaining plate on the arc-shaped plate. Then, rotating the threaded block causes it to move with the cooperation of the first screw. This movement of the threaded block contacts the sliding sleeve, causing it to move. The sliding sleeve's movement, in conjunction with the slider, limit rod, and spring, drives the connecting rod, expanding the arc-shaped plates. When the arc-shaped plates expand to a certain position, they tension the bearing ring, thus fixing it. Next, the splined shaft near the threaded block is inserted into the splined groove on the positioning plate. Then, a telescopic cylinder drives the moving block at the bottom of the moving plate, thus moving the moving plate. The moving plate's movement drives the motor and another rotating shaft. After the rotating shaft reaches a certain position, the splined groove on the rotating shaft engages with the first screw. The splined shaft at one end is inserted, which completes the positioning of the bearing ring. Then, the telescopic cylinder at the other end drives the moving block at the bottom of the base plate to move, thereby further adjusting the position of the base plate and the grinding mechanism. Then, the knob can be turned to drive the second screw to rotate, thereby driving the grinding block to move. When the grinding block moves to the position corresponding to the bearing ring, the motor can be started. The motor drives the splined shaft to rotate through the rotating shaft and spline groove. The rotation of the splined shaft drives the first screw and the bearing ring to rotate. At this time, the grinding block can grind the outer ring of the bearing ring. During the grinding, the user can use another tensioning component to fix the next batch of bearing rings to be ground. Then, they can be ground in the same way. This achieves the ability to grind multiple bearing rings at once, and can also fix, position and grind bearing rings of different sizes, thereby improving practicality. It also makes it convenient for users to grind bearing rings in batches, further improving the ease of use. Attached Figure Description
