Rapid and universal positioning clamp and application method thereof

Abstract

The invention relates to a clamp, in particular to a rapid and universal positioning clamp and an application method thereof. According to the technical scheme, the rapid and universal positioning clamp comprises a base, T-shaped slide blocks, bulb point positioning slide blocks, ejecting blocks, a pressing plate, supporting blocks, pressing screws and an alignment device; the base is provided with a central hole, T-shaped grooves, installation holes and an alignment belt; T-shaped blocks are arranged on the lower portions of the bulb point positioning slide blocks, and spherical segment bodies are arranged on the upper portions of the bulb point positioning slide blocks; the alignment device comprises an alignment plate, positioning pins and alignment pins; positioning holes and a plurality of distance showing holes are formed in the alignment plate; the positioning pins are inserted in the positioning holes and the central hole; and the alignment pins are inserted in the distance showing holes with the sizes matched with the sizes of to-be-machined parts so as to show the installation positions of the ejecting blocks and the pressing plate. By means of the clamp, machined parts can be classified and grouped according to the process similarity and the size similarity, standardization, serialization, specialization and universalization are achieved for the complete set of tool, and a qualitative leap is achieved for the part lean production of factories.

Description

technical field [0001] The invention relates to a fixture, in particular to a fast and universal positioning fixture and an application method thereof. Background technique [0002] In the fierce and global market competition of mechanical processing, it is necessary to improve product quality, reduce costs, and shorten production cycles to bring advanced and qualified products to the market as soon as possible. [0003] In order to improve product quality, reduce costs, and shorten production cycle during mechanical processing, it is necessary to start with the most important link, process design and tooling preparation. The tooling in the manufacturing process includes: cutting tools, fixtures, measuring tools and molds. Among them, the most costly is the fixture. Since a large number of processing operations require clamping, tooling design becomes very important in manufacturing. In order to reduce tooling costs, production setup time and increase production efficiency...

AI Technical Summary

Problems solved by technology

There are many kinds of parts with different diameters and wall thicknesses, especially the deformation of thin-walled parts is a difficult problem in processing. Almost every process requires a fixture, and the number of professional tooling used is large, which is not conducive to reducing the production cost and tooling of enterprises. management

Moreover, when most parts are repaired and processed, the deformation of the parts cannot be completely eliminated due to the use of the stabilized deformed surface as the positioning reference, resulting in the continuation of the deformation in the subsequent process and affecting the final delivery quality of the parts
