Skin stretch combination tool

Abstract

The invention discloses a skin stretch combination tool. The tool comprises a bracket, horizontal regulating mechanisms mounted at four corners in the bottom of the bracket, a first skin clamp mounted at a first end of the bracket, a second skin clamp mounted at a second end of the bracket, a sliding block mounted at the second end of the bracket in a sliding manner and connected with the second skin clamp through a connecting rod, and a jack mounted at the second end of the bracket, wherein a push rod of the jack is connected with the sliding block to push the sliding block to move. The skin stretch combination tool can eliminate deformation and bulging phenomenon of a skin after the welding with a skeleton, and can eliminate deformation of the skin due to temperature difference change after the welding, so that the surface of a carriage is smooth and beautiful, and the quality of an automobile body is largely improved. The tool is suitable for skin stretch in automobile production enterprises, and also can be applied in other fields, such as decoration. The production cost of the tool is low; and the size and the plate thickness of the tool are not restricted.

Description

technical field [0001] The invention relates to the technical field of automobile skin stretching, in particular to a combined skin stretching tool. Background technique [0002] Common processes for automotive skin currently in use are stressed skin stretching and prestressed skin stretching: [0003] 1. Stress skin The skin after stretching is welded or riveted to connect the skin and frame of the car. The disadvantage is that the flatness of the skin is not good, not smooth enough, and not smooth enough. Due to thermal deformation during welding, the skin will loosen, which increases the noise of the vehicle body; [0004] 2. Prestressed skin stretching can reduce the vibration and noise of the car body skin during driving, and the surface of the car skin is smooth and smooth, with high flatness, ensuring the appearance of the car's outer surface, but it is necessary to purchase professional equipment or manufacture large molds, and the cost is relatively high. high. ...

AI Technical Summary

Problems solved by technology

[0003] 1. The stretched skin of the stress skin uses welding or riveting to connect the skin and the skeleton of the car. The disadvantage is that the flatness of the skin is not good, not smooth enough, and not smooth enough.

Due to thermal deformation during welding, the skin will loosen, which increases the noise of the vehicle body;

[0004] 2. Prestressed skin stretching can reduce the vibration and noise of the car body skin during driving, and the surface of the car skin is smooth and smooth, with high flatness, ensuring the appearance of the car's outer surface, but it is necessary to purchase professional equipment or manufacture large molds, and the cost is relatively high. high
