Embodiment Construction

[0029] The first step is to determine the positioning position and clamping position according to the workpiece processing or assembly requirements, determine the adjustment length of each positioning body and clamping body, and determine the series of fixtures;

[0030] The second step is to adjust the special fixed-length tool to the required length, install the positioning head (8) into the positioning seat (9), put it into the tool, and inject the low melting point alloy phase change material (10) under pressure, and at the same time, the auxiliary The cooling device cools the phase change material, and takes out the positioning body (4) after cooling and solidification; the same method is used to make other positioning bodies;

[0031] The third step is to adjust the special fixed-length tool to the required length of the clamping body, then install the clamping height adjustment body (13) into the clamping seat (15), then put it into the tool, and inject the melted low M...

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...
