Description

Technical Field

[0001] The utility model relates to the technical field of harvester spare parts processing, in particular to a polishing and grinding device for processing stable harvester spare parts. Background Art

[0002] The polishing and grinding equipment used for processing harvester parts mainly include belt sanders, polishers and hand-held sandpaper, etc. Belt sanders use rotating belt sandpaper for grinding and polishing, which is suitable for rough grinding, surface finishing and burr removal. Polishers use rotating polishing discs or polishing wheels, combined with polishing agents and polishing pads, to polish and improve the finish of parts. Hand-held sandpaper or abrasive sheets are suitable for local grinding and polishing for finishing and modifying details. These equipment are mainly used for surface finishing, removing oxidation and dirt, improving finish and improving the quality of parts to ensure the flatness, appearance quality and performance of parts.

[0003] For example, a polishing and grinding device for automobile parts proposed in the publication number CN214723048U includes a processing table, a clamping mechanism, a grinding mechanism and a chip removal mechanism on the processing table. Stabilizing bars are vertically welded on both sides of the top wall of the processing table, and a top beam frame welded to the top of two groups of stabilizing bars is horizontally arranged on the processing table. The grinding mechanism includes two groups of trapezoidal seats respectively welded to both sides of the top wall of the processing table and two groups of adjustment components and grinding components respectively arranged on the two trapezoidal seats. The polishing and grinding device for automobile parts, after the first electric push rod of the clamping mechanism is extended and the parts are fixed by the rotating table and the extrusion plate, the operation of the first motor can drive the parts to rotate, thereby adjusting the horizontal orientation of the parts. The extension of the two groups of second electric push rods on the grinding mechanism can drive the two groups of grinding components to change their orientation in the vertical direction, so that the device is suitable for various types of grinding of parts. However, the device still has certain defects when used.

[0004] When the device is in use, it can only clamp and fix the two sides of the part through the electric push rod, which may cause unstable clamping. When clamping some irregular or special-shaped parts, unstable clamping may cause the part to shake, deviate or tilt, affecting the processing accuracy and consistency.

[0005] Therefore, it is necessary to invent a polishing and grinding device for processing stable harvester parts to solve the above problems. Utility Model Content
