Description

Technical Field

[0001] This utility model relates to the field of bolt processing technology, specifically a grinding device for processing hexagonal bolts. Background Technology

[0002] Hex bolts are a type of bolt. Hex screws are commonly used in machinery, mainly because they are easy to tighten and loosen and do not easily slip. They are a very good type of fastening bolt. Nowadays, hex bolts are very common, and their demand is constantly increasing. In the production and processing of hex bolts, the internal hex bolts need to be ground.

[0003] For example, Chinese Utility Model Patent Publication No. CN259759212U discloses a fastening bolt grinding device, including a base, a hydraulic cylinder arranged inside the base, a lifting plate arranged at the upper end of the hydraulic cylinder, a slide rail arranged at the upper end of the lifting plate, a support plate connected to the upper end of the slide rail, a lead screw arranged at the upper end of the support plate, and a movable seat connected to the surface of the lead screw. In this utility model, by setting up a hydraulic cylinder, in conjunction with the slide rail and the slide seat, not only can the lifting of the lifting plate be controlled to adjust the height of the bolt to be ground, but the support plate can also be slid to adjust the distance between the bolt and the grinding wheel. In conjunction with the lead screw and the movable seat, the position of the bolt can be adjusted three-dimensionally, making it convenient for the grinding wheel to grind the surface of the bolt and improving the grinding effect. By setting a fixed frame and a movable frame on the surface of the movable seat, in conjunction with a locking bolt, not only can the bolt to be ground be easily fixed, but bolts of different sizes can also be fixed, which can improve the practicality of the equipment.

For example, when grinding the bolt head, it can only grind the side of the bolt head. If the end face of the bolt head needs to be ground, the bolt needs to be fixed again, which reduces the grinding efficiency. Utility Model Content
