Description

Technical Field

[0001] The utility model belongs to the field of burr removal, and particularly relates to a device for removing burrs from the edges and corners of a disc spring. Background Art

[0002] A disc spring is a spring with a special shape. Its main characteristics are flat and disc-shaped, usually made of metal sheets or metal strips. Due to its flat shape, the disc spring can provide large elastic deformation in a limited space and is suitable for occasions with compact designs. Since disc springs are usually used in applications that require high precision and smooth surfaces, the presence of burrs may affect their function and lifespan. Therefore, dealing with burrs on disc springs is an important step to ensure their quality and performance.

[0003] According to application number: 202322726730.7, a device for removing burrs from the edges and corners of a spring is disclosed, which relates to the field of burr removal technology. It includes a base plate. A first support frame is fixedly connected to the upper right side of the base plate. A threaded rod is rotatably connected to the front side of the lower end of the first support frame. A moving block is threadedly connected to the threaded rod. A rotating motor is fixedly installed on the right side of the moving block through a motor seat. The output end of the rotating motor penetrates through the moving block and is fixedly connected to a clamping assembly. Among them, the clamping assembly includes a mounting plate. A connecting seat is fixedly connected to the left side of the mounting plate. A first sliding groove is formed through the front side of the connecting seat. A second sliding groove is formed through the right side of the connecting seat. A first clamping jaw slides in the front side of the first sliding groove. A notch one is formed through the first clamping jaw. A second clamping jaw slides in the rear side of the first sliding groove. Burrs on both end faces of the spring are removed to make both end faces smooth and flat, ensuring that the quality of both end faces of the spring is the same when in use, and the vibration effects at both ends of the spring are the same when the spring is vibrating.

[0004] The prior art has well solved the problem that the two end faces of the spring may be uneven or irregular, which may lead to uneven mass distribution at both ends of the spring during use, increasing the unbalanced vibration of the spring and affecting the elastic feedback effect of the spring. However, its design is not applicable to flat disc springs, resulting in limited application scope and reduced practicality of the device.

A threaded sleeve 705 is threadedly connected to the surface of the threaded column 704, and the bottom of the threaded sleeve 705 is fixedly connected to the top of the fixing plate 4.

[0032] Example 3

[0033] Reference Figures 1-4 , which is the third embodiment of the utility model, and this embodiment is based on the previous two embodiments.

[0034] In this embodiment, a third motor 10 is fixedly connected to the right side of the right fixed plate 2, and the output shaft of the third motor 10 passes through the right fixed plate 2 and is transmission-connected to the right rotating block 3. The output shaft of the third motor 10 is movably connected to the inner cavity of the right fixed plate 2 through a bearing, and a support column 11 is movably connected to the right side of the left fixed plate 2 through a bearing, and the right end of the support column 11 is fixedly connected to the left side of the left rotating block 3.

[0035] On one side of the two rotating blocks 3 close to each other, clamping plates 12 are provided. A threaded rod 13 is threadedly connected to the inner cavity of the rotating block 3, and one end of the threaded rod 13 is movably connected to the clamping plate 12 through a bearing.

[0037] As Figures 1-4 shown, the third motor 10 is used to drive the rotation of the rotating block 3, thereby driving the rotation of the spring. The surface of the rotating spring rubs against the surface of the grinding rod 8, thereby removing the burrs on the surface of the spring. The threaded rod 13 is used to adjust the position of the clamping plate 12 so that the clamping plate 12 can clamp and fix the edge of the spring. The cooperation of the limiting sleeve 14 and the limiting post 15 can limit the fixing piece 4.

[0038] During use, first place the spring between the two rotating blocks 3 and insert the clamping plate 12 into the gap at the edge of the spring. Then rotate the threaded rod 13 to adjust the position of the clamping plate 12 so that the clamping plate 12 can clamp and fix the edge of the spring. When deburring the gap of the spring, first start the cylinder 708 to extend its output end to move the position of the movable plate 706 until the grinding wheel 6 is located in the gap of the spring. Then start the first motor 701. When the first motor 701 rotates, it can drive the rotating column 5 and the grinding wheel 6 to rotate in cooperation with the two belt pulleys 702, so that the grinding wheel 6 can deburr the spring. When adjusting the position of the trimming gap, it can be carried out by cooperating with the operation of the cylinder 708 for the adjustment of the spring and the operation of the second motor 709 for the adjustment of the position of the grinding wheel 6, so as to comprehensively trim the gap of the spring. When trimming the burrs on the surface of the spring, start the cylinder 708 to contract its output end to move the spring forward until the surface of the spring contacts the surface of the grinding rod 8. Then start the third motor 10. The third motor 10 is used to drive the rotation of the rotating block 3, thereby driving the rotation of the spring. The surface of the rotating spring rubs against the surface of the grinding rod 8, thereby removing the burrs on the surface of the spring.
