Shape Adjusting Tool

Abstract

The invention discloses a profile-followed adjustment frock, including main box, demarcation strip, upper cabin, lower cabin, upper-deck cabin cooling tube, lower cabin cooling tube, freezing liquid, cold-producing medium, floating thimble, centrehole, thimble spring, spring groove, pin bottom outlet, wherein floating thimble is each independently arranged, and each floating thimble can fluctuate under thimble spring and workpiece effect; Demarcation strip is divided into upper and lower two-layer main body case, upper and lower cabin cooling tube is respectively equipped with two sheaf spaces, it is filled with freezing liquid water, take arbitrary shape workpiece to be put in frock, be pressed downward floating thimble, profiling is formed by compression in workpiece shapes syringe needle with the shape, cooling tube is passed through cold-producing medium, sheaf space freezes up and down, and floating thimble positioning, workpiece are wrapped fixing positioning; Coordinate with Digit Control Machine Tool, gun turret milling machine, grinding machine, drilling machine, unstressed clamping and fast clamp are done to abnormal shape, yielding thin-walled, easy spring angle workpiece and minor items, it is ensured that work pieces process quality, precision and working (machining) efficiency.

Description

technical field [0001] The invention relates to the technical equipment field of tooling and fixtures, in particular to a conformal adjustment tooling for clamping and processing workpieces that are difficult to be clamped and processed. Background technique [0002] With the advancement of science and technology, the shapes of workpieces faced in machining are becoming more and more complex, and many workpiece shapes are difficult to clamp and fix, which is not convenient for machining; especially workpieces with 3D curved surfaces, thin-walled workpieces, and tiny workpieces, In the traditional technology, profiling fixtures are used, which are designed by engineers according to the shape of the product, and CNC machine tools are used to process workpiece profiling fixtures, which are used to clamp workpieces for processing, or have to choose high-cost processing technology. [0003] In the prior art, the mechanical processing of complex-shaped workpieces has the following...

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the present invention provides a shape-adjusting tooling. Aiming at the deficiencies in the prior art, the workpiece shape is copied by using the principle of automatic expansion and contraction of the thimble under pressure, and the workpiece is fixed by freezing, which is fast and largely Shorten the design and manufacturing cycle and cost of fixtures and fixtures, improve the effective utilization rate of equipment; overcome the defects of complex design, long production cycle, high processing cost, special-shaped parts, thin-walled parts, and small parts that are not easy to clamp and process in the production of profiling tooling by traditional processing methods ; Provide a low-cost, high-efficiency, simple structure, strong versatility, easy to use conformal adjustment tooling
