Description

Technical Field

[0001] This utility model relates to the field of thread rolling technology, specifically a thread rolling machine that can prevent the stud from rotating. Background Technology

[0002] Studs are headless fasteners with external threads at both ends. During the machining of threaded studs, they need to be fixed on a thread rolling machine. According to application number CN222626065U, a thread rolling machine designed to prevent stud rotation employs a structure that locks the stud in place. Based on a simple clamping structure, it adds a stud-locking and positioning structure, preventing the stud from rotating with the machine during thread rolling. This improves the accuracy and quality of stud thread rolling and provides convenience for users. However, this machine requires two slots, slot one and slot two, which are used to engage locking blocks one and two, respectively. When positioning the stud, locking blocks one and two will engage with slots one and two, respectively. However, when engaging the locking mechanism, the user rotates the first hand crank, which drives the bidirectional screw to rotate. When the locking blocks 1 and 2 are inserted into the locking slots 1 and 2, multiple adjustments are required. If the locking blocks 1 and 2 are not aligned with the locking slots 1 and 2 during insertion, the surface of the stud will be scratched. Utility Model Content
