Embodiment

[0021] see attached Figure 1-3 , the present invention provides a sewing machine cloth feeding presser foot drilling fixture with two holes perpendicular to each other, including a fixture body 1, the shape of the fixture body is a cube, and a rectangular opening groove 6 is horizontally provided on one side of the fixture body. The rectangular opening groove is connected with the pressing mechanism, and the jig body is provided with a drilling mold. The bottom edge of the rectangular opening groove is parallel to the side of the fixture body, constituting the positioning base surface of the fixture. The width and depth of the rectangular opening groove match the width and thickness of the workpiece. Two drilling molds of φ3.8 and φ3 are set on the fixture body corresponding to the designed holes of the workpiece, and the drilling molds are arranged at right angles to each other to complete the processing of two holes at right angles to each other. Drilling jigs (3) The ...

Abstract

The invention relates to a drilling fixture for two vertical holes on a fabric-feeding presser foot of a sewing machine. The drilling fixture is characterized by comprising a fixture body, wherein the fixture boy is square; one side surface of the fixture body is transversely provided with a rectangular open slot; the rectangular open slot is connected with a pressing mechanism; the fixture body is provided with drill jigs. The drilling fixture has the beneficial effects that the workpiece is accurately and reliably located by virtue of the appearance; the drill jigs for processing different holes are arranged on different surfaces of the fixture body, and the holes of different surfaces are processed by virtue of overturning of the fixture; all parts are arranged on the fixture body, so that the structure is simple and compact; the workpiece processing quality is ensured; after new products are on the market, the newly-increased annual profit of an enterprise is more than 125 thousand.

Description

technical field [0001] The invention belongs to a tooling fixture, in particular to a drilling fixture with two holes perpendicular to each other on the cloth feeding presser foot of a sewing machine. Background technique [0002] The sewing machine presser foot is an essential part of the feeding mechanism of the sewing machine. Various types of sewing machine presser feet play a very important role in the production process, such as special sewing machine presser feet for top thread and invisible zippers, Pleating sewing machine presser feet, etc., it is very important to choose different sewing machine presser feet in different sewing operations. [0003] Industrial sewing machine piano cloth feeding presser foot is a newly developed product of the new industrial sewing machine. Its structure is complex, and the dimensional accuracy and machining accuracy requirements of each part of the structure are very high. Using digital processing centers to process one by one, th...
