Fixture special for straightening and correcting vehicle door profile

Abstract

The invention provides a fixture special for straightening and correcting a vehicle door profile, and relates to the field of vehicle door profile machining equipment. The fixture comprises two parallel vertical plates, and an upper row of rollers and a lower row of rollers are installed between the two vertical plates, wherein the total number of the upper row of rollers is four, and the total number of the lower row of rollers is five. The upper row of rollers and the lower row of rollers are arranged in a staggered mode, the same sides of all the rollers are each coaxially provided with a gear, the adjacent rollers are transmitted through meshing of the gears, first grooves and second grooves are formed in the roller faces of the upper row of rollers, first protruding parts are arranged between the first grooves and the second grooves, third grooves and fourth grooves are formed in the roller faces of the lower row of rollers, second protruding parts are arranged between the third grooves and the fourth grooves, the upper row of rollers and the lower row of rollers are oppositely combined, the first protruding parts are inserted in the third grooves, and the second protruding parts are inserted in the second groves. The fixture can be used for straightening and correcting the formed vehicle door profile which is distorted and is not straight, the mode that the nine rollers are arranged in the two rows with the four rollers in the upper row and the five rollers in the lower row in the staggered mode is adopted, and the rollers are curved repeatedly so as to make the curvature tends to be consistent until the vehicle door profile is flat and straight.

Description

technical field [0001] The invention relates to the field of processing equipment for car door profiles, in particular to a special tool for straightening car door profiles. Background technique [0002] The door profile is formed by roll forming process. The metal plate passes through a series of continuous rollers to achieve continuous primary deformation and finally obtain the predetermined shape. However, the profile of the car door is twisted and not straight after roll forming, and the cross-sectional dimension cannot meet the tolerance requirements, which cannot meet the requirements of car door manufacturing. Contents of the invention [0003] The purpose of the present invention is to provide a special tool for straightening and straightening car door profiles, so as to solve the above technical problems. [0004] The technical problem to be solved by the present invention adopts the following technical solutions to realize: [0005] A special tool for straighte...
