Abstract

The invention relates to a skin tensioning tool, and belongs to the field of vehicle manufacturing. The skin tensioning tool comprises a support unit and a tensioning unit, the support unit comprises two first transverse pieces and two first longitudinal pieces, and the two first longitudinal pieces are perpendicularly connected between the two first transverse pieces; first clamping pieces are arranged at the two ends of the two first transverse pieces correspondingly and used for clamping a door frame of a vehicle body. The number of the tensioning units is two, the two tensioning units are arranged on the sides, away from the center of the first transverse piece, of the two first longitudinal pieces in a one-to-one correspondence mode, second clamping pieces are arranged on the sides, away from the center of the first transverse piece, of the two tensioning units, and the second clamping pieces are used for clamping the skin. The first transverse piece can stretch out and draw back in the length direction so as to adapt to the width of a door frame. The tensioning unit can stretch out and draw back in the length direction parallel to the first transverse piece so as to tension the skin. The problem of skin waste in the prior art is solved.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle manufacturing, in particular, to a skin tensioning tool. Background technique [0002] In the related technology, when skinning the side wall of a bus, the designer first provides a complete incoming skin material, and its length is usually the length of the vehicle body plus the reserved 300mm process mask at both ends of the front and rear. leather length. During the specific operation, the side panel skin is placed on the position of the body to be processed, and then the skin is stretched at both ends of the body with a hydraulic stretching machine. When the skin is stretched to about "L" × 0.8‰ For length, use a resistance spot welder or a CO2 welder to weld each stress point of the side skin to the side frame of the vehicle body. [0003] However, there are the following disadvantages in the above skin stretching method: [0004] For a bus with a middle door, after the stretching...
