Description

Technical Field

[0001] This utility model relates to the field of self-drilling screw technology, and in particular to a machining tooling for self-drilling screws. Background Technology

[0002] A self-tapping screw is a special type of screw with a drill bit and threads, capable of automatically drilling and tapping its own threads during installation. To ensure the processing and installation quality of self-tapping screws, specialized tooling is usually required for their fabrication.

[0003] Existing self-drilling screw processing fixtures involve placing the self-drilling screw in a fixed slot of a fixed frame, then rotating the fixed frame to move the self-drilling screw into a self-drilling machine for drilling. However, because the connection between the self-drilling screw and the fixed frame is not reinforced, the self-drilling screw is prone to falling out of the fixed slot during drilling, affecting processing efficiency. Therefore, this solution proposes a new processing fixture for self-drilling screws to address these issues. Utility Model Content
