Abstract

A multifunctional special-shaped fixing jig is of a cuboid structure, and four cavities are formed in the end face of the jig body. The die cavity is of a cuboid structure. The four cavities have the same shape and different areas. The side walls of the three large cavities are respectively provided with a threaded hole, and two ends of each threaded hole are communicated with the inner wall of each cavity and the outer surface of the side wall of the jig body. A bolt is inserted into each threaded hole. Outer chamfers are respectively arranged at four rectangular right angles of the jig body. An inner chamfer is arranged on a right angle close to the outer chamfer on the four cavities. The jig enables clamping to be simple and is convenient to operate. For example, when a round workpiece is to be machined, the workpiece is placed in the intermediate cavity and fixed. Because the right-angle side, the parallelism and the verticality of the multifunctional special-shaped fixing jig are all within 0.003miu, the complicated steps of supporting and aligning are not needed. The method has the advantages of realizing simplification of steps and processing, ensuring the requirement of tolerance and saving time.

Description

Multifunctional abnormal-shaped fixing jig

Technical Field

The utility model belongs to grinding apparatus processing field, in particular to fixed tool of multi-functional abnormal shape.

Background

In the abrasive industry, there are many irregular parts, and a set of abrasive tools has many irregular shapes such as circles, squares, triangles, and the like. Many wire-cut electrical discharge machines need to process, but when a part is placed on a processing table of the wire-cut electrical discharge machine, the clamping and the plane alignment are very tedious, because the processing needs to find a processing reference of the part so that the part can meet the spurious tolerance requirement. The shape of a part to be machined needs to be machined on a machine table, then the part to be machined is placed in the shape which is machined firstly, and the part needs to be machined, so that time waste is caused, and the part cost is overhigh.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a multi-functional abnormal shape fixed tool. The problems of complicated processes of clamping and aligning planes, time waste and overhigh processing cost in the process of processing the special-shaped part of the grinding tool in the prior art are solved.

In order to solve the technical problem, the following technical scheme is adopted:

the utility model provides a multi-functional heterotypic fixed tool, includes the fixture body of S136 material, its characterized in that:

the jig body is of a cuboid structure, and four cavities are formed in the end face of the jig body. The die cavity is of a cuboid structure. The four cavities have the same shape and different areas. The side walls of the three large cavities are respectively provided with a threaded hole, and two ends of each threaded hole are communicated with the inner wall of each cavity and the outer surface of the side wall of the jig body. A bolt is inserted into each threaded hole.

Outer chamfers are respectively arranged at four rectangular right angles of the jig body. An inner chamfer is arranged on a right angle close to the outer chamfer on the four cavities.

The advantages are that: the jig enables clamping to be simple and is convenient to operate. For example, when a round workpiece is to be machined, the workpiece is placed in the intermediate cavity and fixed. Because the right-angle side, the parallelism and the verticality of the multifunctional special-shaped fixing jig are all within 0.003miu, the complicated steps of supporting and aligning are not needed. The method has the advantages of realizing simplification of steps and processing, ensuring the requirement of tolerance and saving time. The processing of irregular and variable parts is complex, the simplification is that time is saved and profits are created for companies, and the annual profit of the companies is increased by 3% by the multifunctional special-shaped fixed jig.
