Universal tool for clamping light parts and clamping method

Abstract

The invention provides a universal tool for clamping light parts. The universal tool comprises a tool body and a positioning datum plate (3); the upper surface of a tool box body (1) is a clamping working surface (2); a liquid trough (12) is formed in the tool box body (1) and filled with a phase-change material (11); a phase-change liquid injection hole (8) and a phase-change liquid flow-out hole(13) are formed in the side wall of the liquid trough (12); a tool tight-pressing body (7) which performs clamping with a machine table is disposed on the lower portion of the tool box body (1); thepositioning datum plate (3) is fixed to the clamping working surface (2); both an upper surface A and a lower surface B of the positioning datum plate (3) are designed into positioning surfaces; and the positioning datum plate (3) is larger than a trough opening of the liquid trough (12). The invention further relates to a clamping method for clamping the light parts. Accordingly the machining quality of double-sided light parts can be guaranteed even without a special profile tool, the part machining cost is reduced, and the production preparation period is shortened.

Description

technical field [0001] The invention relates to a universal tool for clamping light parts; the invention also relates to a clamping method for clamping light parts. Background technique [0002] Lightweight parts, such as foam and composite materials, have the advantages of light weight and high strength in the load-bearing direction, and have been widely used. For double-sided lightweight parts, after the first surface is processed, the second surface is processed , usually use special surface tooling to clamp and position the parts. There are several common clamping methods for lightweight parts clamping: [0003] The first is to use double-sided tape to realize the clamping and holding of lightweight parts. This clamping method is easy to operate and has been widely used. However, this method is usually suitable for single-sided parts, and cannot be clamped for double-sided lightweight parts; [0004] The second is to use magnetic fields and tribological principles to...

Problems solved by technology

[0007] In order to solve the problem that the double-sided lightweight parts in the prior art require special profile tooling, which increases the processing cost of the parts, prolongs the production preparation cycle of the parts, and increases the uncontrollable factors in the production process of the parts, the present invention provides A general-purpose tooling for clamping lightweight parts is characterized in that: it includes a tooling body and a positioning reference plate; the tooling body includes a tooling box, and the upper surface of the tooling box is a clamping work surface, so The inside of the tooling box is a liquid tank, and the phase change material is filled inside the liquid tank, and the side wall of the liquid tank is provided with a phase change liquid injection hole and a phase change liquid outflow hole, and the phase change liquid injection Both the hole and the phase change liquid outflow hole communicate with the outside world through the tooling box body, and the lower part of the tooling box body is provided with a tooling compacting body clamped with the machine tool workbench; the positioning reference plate is fixed in the clamping work On the surface, the upper surface and the lower surface of the positioning reference plate are made into positioning surfaces, and the positioning reference plate is larger than the notch of the liquid tank
