Universal flexible clamp and using method thereof

Abstract

The invention relates to a universal flexible clamp and a using method thereof. The universal flexible clamp comprises a base, a phase-change material cavity, a phase-change material, positioning bodies and clamping bodies. The phase-change material cavity is connected with the base through screws. The positioning bodies are placed on the base through numerical control positioners, and are attracted to the base through bottom permanent magnets. The clamping bodies are placed on the base through numerical control positioners, and are attracted to the base through bottom permanent magnets. The phase-change material is poured for making the positioning bodies, the clamping bodies, the phase-change material cavity and the base be fixedly connected together and form a set of the clamp. According to the universal flexible clamp, the length of the positioning bodies can be continuously adjusted, the height of the clamping bodies can be continuously adjusted, and the position of the positioning bodies and the clamping bodies can be arranged arbitrarily, so that the clamping of parts with arbitrary complicated shapes and sizes is achieved. Parts of the clamp are simple in shape and low in manufacturing precision requirement, so that the manufacturing cost of the clamp is low. The phase-change material can be used repeatedly, so that the remanufacturing and recycling of the clamp are easy.

Description

technical field [0001] The invention relates to the technical field of mechanical processing and assembly, in particular to a flexible fixture based on phase-change materials, which can truly realize installation, positioning and clamping of parts of any shape and size. Background technique [0002] At present, 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 ...
