Description

Technical Field

[0001] This utility model relates to the field of mechanical parts grinding, and in particular to a mechanical parts grinding device. Background Technology

[0002] After producing some mechanical parts, the blank parts will have some burrs. At this time, we use a coarse grinding wheel to grind them. The advantage of using a coarse grinding wheel is that it can quickly remove burrs. Then we need to change to a finer grinding wheel, and then we need to use sandpaper with different grinding precision. Moreover, the grinding precision of different parts is also different, so multiple machines need to be frequently changed. Therefore, based on this technical problem, we designed a mechanical parts grinding device. Summary of the Invention

[0004] The dual-output shaft motor has a limit ring on each side of the shaft passing through the first support plate. The shaft ends are threaded. The grinding wheel is inserted into the shaft to hold the limit ring, and then a washer is inserted and installed with a nut.

[0005] The two second driven wheels are coaxially arranged, and two second support plates are symmetrically arranged on opposite sides of the two second driven wheels. The shaft connecting the two second driven wheels can rotatably pass through the two second support plates.

[0006] Bearings are fitted at the ends of the shafts passing through the two second support plates and at the ends of the dual-output motors passing through the first support plate.

[0007] Two first driven wheels are rotatably mounted on a concave plate below the concave plate. A tensioning cylinder is provided below the concave plate. The air rod of the tensioning cylinder is connected to the concave plate. The tensioning cylinder is mounted on a horizontal plate below the horizontal plate, which is mounted on a second support plate.

[0008] The beneficial effects of this utility model are as follows: This device uses a dual-output shaft motor to drive multiple sandpapers and grinding wheels for grinding. Workers can change different sandpapers and grinding wheels to perform different types of grinding in the same position according to their grinding needs, making grinding convenient and reducing the cumbersome use of different grinding machines.
