Description

Technical Field

[0002] The needle bar is an important part of the sewing machine, which plays the role of transmitting the power of movement to the working mechanism. Its working conditions require that the needle bar has high strength, wear resistance and fatigue resistance, and requires sufficient rigidity and toughness. Currently, when processing the needle bar, it is necessary to use a clamp to position it first.

[0003] The needle bar holding fixture on the milling machine disclosed in the Chinese utility model patent application disclosure CN201833207U positions the needle bar holding round rod through the through hole of the limit block, and then clamps the needle bar holding head with the head end face of the bolt and the top surface of the support block, thereby positioning and clamping the needle bar. In this way, after one clamping, the four processes of drilling and chamfering, milling slots and chamfering can be completed, saving the respective fixtures and reducing the mold manufacturing cost. Moreover, each process requires a worker to operate, the quality of the parts can be stable, and there is no need for circulation, which improves the processing efficiency. During clamping, the needle bar is clamped by the extension and contraction of the first cylinder. After processing, the needle bar is ejected by the second cylinder, which also makes the processing efficiency high. However, the current fixture cannot limit needle bars of different models, and the overall practicality is low. Utility Model Content
