Problems solved by technology

[0004] Small push rod parts in sewing machine parts, see attached Figure 1-3, it mainly includes the rod part and the end of the rod, wherein the end of the rod has a The through hole, the horizontal left and right direction refers to the direction perpendicular to the length of the rod. There is a groove in the middle of the end of the rod. Since the groove needs to be matched with other parts during installation, the accuracy requirements are relatively high. High, so generally the groove needs to be machined after casting, so as to ensure its cooperating installation with subsequent parts. However, the existing fixture cannot locate the small plunger during machining, and a special fixture is needed to realize its positioning. Machining of the finished groove

Abstract

The invention discloses a special fixture for machining a groove on a small pressure bar. The ends of the pressure bar are positioned by a first positioning bar and a second positioning bar of the fixture, and a shank of the pressure bar is positioned by a V-shaped block and a pressure plate of the fixture. The special fixture is simple in structure and convenient to operate. The small pressure bar is effectively positioned and clamped by the special fixture so as to facilitate machining.

Description

[0001] technical field [0002] The invention relates to a special fixture for processing small plunger grooves. [0003] Background technique [0004] For the small pressing rod parts in the sewing machine parts, see the attached Figure 1-3 As shown, it mainly includes the rod part and the end part of the rod, wherein the end part of the rod has a through hole penetrating along the horizontal left and right direction. The horizontal direction refers to the direction extending perpendicular to the length of the rod part. There is a groove in the middle, because the groove needs to cooperate with other parts during installation, and its precision requirements are high, so the groove needs to be machined after casting to ensure its matching with subsequent parts. Existing fixtures can't locate the small plunger during processing, and special fixtures are needed to realize its positioning and complete the processing of the groove. [0005] Contents of the invention [00...
