Description

Technical Field

[0001] This utility model relates to the field of gasket processing, and in particular to a gasket deburring machine. Background Technology

[0002] A gasket, also known as a washer, is a part placed between a connected component and a nut. It is generally a flat metal ring used to protect the surface of the connected component from scratches by the nut and to distribute the pressure exerted by the nut on the connected component. Gaskets are usually produced by stamping, but stamped gaskets may have burrs and rough edges. In actual processing, deburring is necessary to prevent scratches on the product during use.

[0003] Currently, sandpaper is commonly used for polishing, but this method cannot polish the inner wall surface of the gasket. It requires further scraping of the inner ring with a scraper, which is cumbersome. Furthermore, due to the small size of the gasket, it is difficult for workers to observe the deburring process on the inner ring. Therefore, it is necessary to improve this structure to overcome these shortcomings. Utility Model Content

[0034] The working principle of this utility model is as follows:

[0035] The first drive cylinder is pushed out, causing the mounting plate to move up, which in turn moves the base plate up.

[0036] The drive rod and the grinding rod are separated;

[0037] Place the shim onto the grinding rod;

[0038] The first drive cylinder retracts, causing the substrate to move downwards, and the drive rod and the grinding rod to contact and engage.

[0039] The second drive cylinder extends, causing the grinding block to contact the side of the shim, thereby keeping the shim and the grinding rod in contact;

[0040] The drive motor rotates, causing the grinding rod to rotate together with the drive rod, and the pad rotates under the friction of the grinding rod;

[0041] Because the rotation speeds of the shim and the grinding rod are not the same, friction can still be achieved between them, thus achieving friction on the inner surface.

[0042] The outer surface of the pad rubs against the grinding block to achieve grinding;

[0043] After the inner and outer surfaces are sanded;

[0044] The second drive cylinder retracts, causing the grinding block to move away from below the upper grinding plate;

[0045] The first drive cylinder continues to retract, causing the upper grinding plate to continue to descend until the upper grinding plate contacts the upper surface of the pad.

[0046] At this point, the drive rod compresses the spring and retracts into the mounting stepped hole;
