[0002] Automobile manufacturing includes the manufacturing of automobile parts, the testing of automobile parts, the assembly of automobiles and the testing of automobiles. Usually, the manufacturing of automobile parts requires the use of molds for processing. In order to improve the quality of various automobile parts, it is necessary to produce and process each automobile part separately, and then use various processing equipment to perform fine processing such as punching, grinding, deburring, trimming, etc. Finally, the various parts are assembled together through the assembly line. After the whole vehicle is assembled, the vehicle can be put into testing and can be put into the market after passing the inspection.

[0003] Automobile parts are made of iron materials. In order to ensure the smoothness of the parts surface, the iron parts need to be polished.

Under the action of multiple groups of linkage rods and the round block, the iron component to be ground is fixed to the top of the workbench. The operation is convenient and it is convenient to clamp and fix cylindrical iron components of different sizes. Then, according to the size of the cylindrical iron component to be ground, the linkage screw is rotated to drive the connecting block to move, so as to adjust the distance between the grinding block and the cylindrical iron component to be ground, and then the servo is started. The motor drives the connecting disk to rotate, and then drives the cylindrical iron parts to rotate. The pulley transmission structure is used to synchronously drive the threaded rod to rotate, and then drives the linkage seat to move. When the cylindrical iron parts rotate, the grinding block synchronously translates and grinds them, thereby improving the grinding efficiency. The structure is simple and only one servo motor is used to drive it, thereby reducing the production cost. By setting up a dust suction component, when the threaded rod rotates, the driving bevel gear is used to drive the driven bevel gear to rotate, thereby driving the dust suction blades to rotate. The dust suction box, the dust suction hose and the dust suction box can be used to suck and clean the iron filings produced by grinding, thereby improving the grinding effect. The adsorption block is used to adsorb the iron filings, which is convenient for processing and does not require additional driving force. The cost of use is low.
