Quick-change clamp for welding steering wheel decorative cover and using method of quick-change clamp

Abstract

The invention discloses a quick-change clamp for welding a steering wheel decorative cover and a using method of the quick-change clamp. The quick-change clamp comprises a decorative cover placing mechanism, a base, a side edge clamping mechanism, two clamping locks and a pneumatic clamping mechanism. The dual-purpose air pump is used for synchronously inflating the outer telescopic air bag and the inner telescopic air bag, the outer telescopic air bag expands towards the top and the outer side and is tightly clamped on the inner side and the outer side of the steering wheel decorative cover, the inner telescopic air bag and the outer telescopic air bag are unsaturatedly filled with magnetic powder, and the magnetic powder can be extruded on the two sides of the steering wheel decorative cover under the action of magnetic attraction force; according to the clamping device, the steering wheel decorative cover in a complex shape can be completely attached, stress is more uniform during clamping, the problem that the structure of the steering wheel decorative cover is damaged due to overlarge external stress is solved, the problem that the structure is damaged due to stress on one side can be avoided, the replacement efficiency of clamping work is improved, and the replacement cost is reduced. And the completeness of the surface of the clamped object can be greatly guaranteed, and the cost of customizing a die conforming to the clamped object due to different shapes is reduced.

Description

technical field [0001] The invention relates to the technical field of auto parts processing equipment, in particular to a quick-change clamp for welding a steering wheel trim cover and a method of using the same. Background technique [0002] With the development of the automobile industry, in order to pursue a more personalized and beautiful car interior, the types of materials used in the interior of the car are gradually increasing. When it is made of metal material, it cannot be integrally formed due to the limitation of its shape / installation method, so it is necessary to use a corresponding fixture to limit the position and then weld it. [0003] In the prior art, such as the Chinese Patent No.: CN 211390212 U "a quick-change clamp for welding steering wheel trim cover", it includes a fixed bottom plate and a welding splint arranged on the fixed bottom plate; the top of the welding splint is provided with a Triangularly distributed trim cover welding seats; the fixed...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a quick-change fixture for welding a steering wheel trim cover and its use method, in order to solve the above-mentioned background technology. When in position, an external stress pointing inward is often applied on the outside, and after the outside of the metal sheet with a certain shape is squeezed, it is easy to deform inwardly, which not only makes the shape of the welded steering wheel trim appear larger Deformation, and even damage part of the bending structure, so that it is clamped with the matching positioning plate seam, it is difficult to take it out and cannot realize the problem of quick change work
