Special tool for surface grinder for machining demagnetized micro-dimension part

Abstract

A special tool for a surface grinder for machining a demagnetized micro-dimension part comprises an adjustable base body, four displacement systems symmetrically installed on the periphery of the adjustable base body, and an external negative pressure system. The adjustable base body comprises a groove-shaped base (1) with a rectangular internal groove, and a rectangular adsorption platform (11) capable of ascending and descending along the internal groove of the base. The rectangular adsorption platform is of a hollow multi-hole structure, wherein the rectangular adsorption platform is provided with an inner cavity, and a top plate of the rectangular adsorption platform is provided with adsorption holes (11-1) distributed evenly. One or two sides of the rectangular adsorption platform areprovided with negative pressure adsorption ports provided with air pipe connectors (15) in a matched mode. The groove-shaped base is positioned and installed on the working tabletop of the surface grinder through installing bearing platforms (1-2) and fixing screws (3) at the four external corners of the groove-shaped base, or is adsorbed and positioned on the working tabletop of the surface grinder through magnetic metal (2) installed on the bottom surface of the groove-shaped base in an embedded mode. Each displacement system comprises a clamp assembly capable of moving horizontally and a lifting device. The special tool for the surface grinder for machining the demagnetized micro-dimension part is capable of reducing the labor intensity of workers, efficient in clamping and high in machining efficiency.

Description

technical field [0001] The invention belongs to the technical field of grinding machine tooling, and in particular relates to a special tooling for surface grinding machines used for processing degaussing micro-sized parts. Background technique [0002] With the continuous advancement of technology, the production and processing of precision parts tends to be diversified and personalized, and the flexible and changeable size and structure of parts will lead to the increasing difficulty of parts processing. In the process of processing parts in modern mechanical processing enterprises, the processing accuracy is not only based on the accuracy of machine tool equipment and tool grinding tools, but also affected by the tooling used. The flexible and changeable design of parts not only puts forward more challenges for processing equipment and tools themselves At the same time, it also puts forward higher requirements for the tooling of the equipment. Only when all aspects meet t...

AI Technical Summary

Problems solved by technology

[0003] Degaussing micro-sized parts refer to non-magnetic small-sized metal parts and non-metallic parts, such as thin sliders made of 1Cr18Ni9Ti and LD10, guide bars made of bakelite, etc. The processing characteristics and requirements are that the working surface of the parts must have a level of 1.6 or 0.8 or even The above surface roughness requirements, accompanied by parallelism and other positional requirements and higher tolerance level requirements, and the working surface must not be damaged or indented during the processing process, the existing methods and tools for processing degaussed micro-sized parts include: electromagnetic Iron adsorption tooling, basic flat tooling, etc., because the electromagnet adsorption tooling is based on the electromagnetic adsorption theory, the workpiece is positioned on the surface of the tooling, which makes the tooling unable to apply to non-magnetic materials

The basic flat tooling is a building block combination tooling, which can be spliced ​​with a variety of tooling forms to match the characteristics of the corresponding workpieces. However, the positioning method of the workpieces mostly adopts compression positioning, which is easy to form indentations and damage the contact surface. Problems that are difficult to locate and operate

These methods and tooling have many problems such as insufficient adaptability, difficult clamping, not easy to fix, and easy to damage the use surface.
