Flexible clamp based on phase-change material

Abstract

The invention provides a really flexible clamp device capable of clamping parts with any complex shapes and sizes. The flexible clamp device provided by the invention comprises a base, a phase-change material cavity, a phase-change material, a locating body, a clamping body and the like. The phase-change material cavity is connected to the base through a bolt; the locating body is placed on the base through a numerical control locating machine and adsorbed on the base through a bottom permanent magnet; the clamping body is placed on the base through the numerical control locating machine and adsorbed on the base through the bottom permanent magnet; and phase-change material is cast so that the locating body, the clamping body, the phase-change material cavity and the base are fixedly connected to form a clamp. The length of the locating body can be continuously adjusted, the height of the clamping body can be continuously adjusted, and positions of the locating body and the clamping body can be arranged randomly, so that clamping the parts with any complex shapes and sizes is realized. The clamp is simple in part shape, low in manufacturing precision requirement and low in clamp manufacturing cost; and the phase-change material can be repeatedly used so as to be easy for remanufacturing and cyclic utilization.

Description

technical field [0001] The invention belongs to the field of mechanical processing and assembly, and relates to a flexible clamp based on phase-change materials, which can truly realize the installation, positioning and clamping of parts of any shape and size. Background technique [0002] With the advancement of technology, people's demand for products is becoming more and more changeable, personalized and diversified. It is reflected in the shorter and shorter product life (fast replacement), more and more new products, and smaller and smaller product batches. These pose great challenges to manufacturing companies. The sizes and shapes of the processed parts are various, and there is no predictability at all. In order to reduce the design and manufacture time of fixtures and shorten the production preparation time, only flexible fixtures are used. The flexible fixture means that the same fixture can complete the positioning and clamping of parts of different types and si...

AI Technical Summary

Problems solved by technology

[0006] 1) High quality requirements for combined components;

[0007] 2) The initial purchase fee is high;

[0008] 3) Since it is formed by combining and superimposing "building blocks", this kind of flexible fixture has poor rigidity and is difficult to adapt to heavy cutting;

[0009] 4) Difficult to clamp irregular shape parts;

[0011] 6) Assembly and debugging require high technology;

[0012] 7) Many types and quantities of parts require professional management, and the cost of use and management is high;
