[0002] In modern industrial production, thread-retaining stud bolts, due to their excellent fastening properties, are widely used in numerous fields, including automotive manufacturing, aerospace, and mechanical equipment. As critical connecting components, the machining accuracy and surface quality of thread-retaining stud bolts directly impact the stability and reliability of the overall structure. Grinding is a crucial step in the production of thread-retaining stud bolts. Its primary purpose is to remove material to achieve the required dimensional accuracy, surface roughness, and thread profile, ensuring that the bolts perform effectively in actual use.

[0003] There are some common problems with the existing anti-slip thread stud bolt grinding equipment. Traditional equipment lacks efficient and accurate positioning and adjustment mechanisms in the workpiece clamping link, and is difficult to adapt to stud bolts of different specifications and sizes, resulting in low clamping efficiency and difficulty in ensuring clamping accuracy, which easily leads to processing errors. The workpiece positioning system is not stable enough and lacks a multi-dimensional limit adjustment mechanism, making it difficult to adapt to the clamping requirements of bolts of different specifications, resulting in the bolts being easily offset during the grinding process, causing the thread surface roughness to exceed the standard or dimensional deviation. Based on this, a grinding equipment for anti-slip thread stud bolt processing is proposed to solve the above problems. Summary of the Invention
