Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts, in particular to a grinding device for processing automobile bolts. Background Art

[0002] ‌Automobile bolts are high-strength bolts used to connect various parts of automobiles. They usually consist of two parts: a head and a screw (a cylinder with external threads). Bolts firmly fix two or more parts and play a role in tight connection. They can withstand tensile forces, so many projects require bolts to ensure the stability of the connection.

[0003] At present, automobile bolts need to be polished during the production process. In order to save time and effort, the bolts are usually fixed with a device and then polished with a polishing device. However, this method requires the previous bolt to be polished and removed before the next bolt is installed, which wastes time, prolongs the working cycle, and reduces work efficiency.

[0004] To this end, we provide a grinding device for automobile bolt processing to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a grinding device for automobile bolt processing, which drives the driving gear to move by moving the first belt. When the driving gear contacts the driving rack, the driving gear and the bolt rotate, and then the screw rod grinds 360 degrees while moving, thereby improving the grinding efficiency. At the same time, multiple groups of fixing blocks are arranged on the first belt, so that multiple bolts can be installed, thereby improving the grinding efficiency and shortening the working time. The problem that the existing method needs to install the next bolt after the previous bolt is ground and removed, which wastes time, prolongs the working cycle, and reduces the working efficiency is solved.
