Abstract

The invention relates to a fixture for a part of a sewing machine. The part is stripped and is provided with a side face; a stripped through groove and a circular through hole are arranged in the side face; the fixture is used for fixing the part on a drilling machine; the drilling machine is used for drilling a hole in the side face of the part; the fixture comprises a fixed seat which is detachably connected with the drilling machine, a locating sleeve which is vertical to and fixedly connected with the fixed seat and a bolt which is in threaded connection with the locating sleeve; a plurality of crevices are formed on the side wall at the upper section of the locating sleeve; each crevice is parallel to the axis of the locating sleeve; and when the bolt is tightened, the external diameter of the locating sleeve is increased, and the locating sleeve is clamped in the through hole. In the invention, the locating sleeve with the crevices is split through the bolt, so that the outer wall of the locating sleeve is tightly clamped in the through hole of the part, and the part is firmly fixed on the fixture. The fixture is easy to operate, and the processing efficiency is increased.

Description

[0001] technical field [0002] The invention relates to a fixture for sewing machine parts. [0003] Background technique [0004] At present, most of the sewing machine parts that have elongated through grooves and circular through holes and need to be drilled use elongated through grooves to fix the parts, but the elongated fixing parts with matching through grooves are manufactured. The fixture of the block is more difficult, the shape of the fixed block is not easy to process, and the part is fixed by the long fixed block, which may indirectly affect the accuracy of the hole position because the precision of the part itself is not high. [0005] Contents of the invention [0006] The object of the present invention is to provide an easy-to-operate sewing machine parts fixture. [0007] In order to achieve the above object, the technical solution adopted in the present invention is: a sewing machine part fixture, the part is in the shape of a strip, the part has a s...
