Embodiment 1

[0024] This embodiment is basically as attached figure 1 Shown: a fixture for repairing automobile sheet metal parts, including a workbench 1, a clamping device and a support device, both of which are connected to the workbench 1. The clamping device includes two pairs of clamping frames, and the two pairs of clamping frames are symmetrical along the workbench 1 left and right. The clamping frame is divided into an upper clamping frame and a lower clamping frame.

[0025] The lower clamping frame includes the first vertical rod 2 fixed on the workbench 1 and the first roller 3 hinged on the end of the first vertical rod 2, the first roller 3 is covered with a magnetic layer, the circular shape of the first roller 3 A first ratchet 4 is fixed on the surface, and a first pawl 5 that can be inserted into the teeth of the first ratchet 4 is hinged on the first vertical rod 2 .

[0026] The upper clamping frame includes a second vertical rod 6 fixed on the workbench 1 , a connect...

Embodiment 2

[0037] Such as figure 2As shown, the difference between this embodiment and Embodiment 1 is that the strut 11 is a telescopic structure, and the strut 11 is two sections of rods 15 connected by threads. After pole 11 contacts with sheet metal, owing to need knocking directly above pole 11, screw thread can make the length of pole 11 shorten 5mm, and the sheet metal directly above pole 11 is reset downwards.

Abstract

The invention discloses a clamping method for a to-be-repaired automobile stamping part. The clamping method includes the following steps that firstly, locking mechanisms are unlocked, connecting rods of upper clamping frames are lifted, and the connecting rods are locked through the locking mechanisms; secondly, gas in a gas bag is exhausted, and supporting rods are in the state with the smallest height; thirdly, the stamping part is put on first idler wheels, the first idler wheels are attracted to the lower surface of the stamping part, the locking mechanisms are unlocked, the connecting rods of the upper clamping frames are put down, second idler wheels are attracted to the upper surface of the stamping part, and the connecting rods are locked through the locking mechanisms; and fourthly, the gas bag is inflated, and inflation is stopped when the supporting rods tightly abut against the stamping part. By means of the clamping method, the stamping part needing to be knocked to be repaired and corrected is well positioned, an operator only needs to be absorbed in knocking a repaired part, physical force of the operator can be saved, and the repairing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of positioning or fixing of workpieces, in particular to a clamping method for automobile sheet metal parts to be repaired. Background technique [0002] Sheet metal is a comprehensive cold working process for thin metal plates (usually below 6mm), including shearing, punching / cutting / compositing, folding, welding, riveting, splicing, forming, etc. Its notable feature is that the thickness of the same part is the same. The products processed by the sheet metal industry in the world are called automobile sheet metal parts. The most common automobile sheet metal parts are the metal body of the automobile, that is, the engine cover, roof cover, trunk lid, door panel, fender, etc. . [0003] With the sharp increase in car ownership, car collision accidents are also on the rise. If the appearance of the car body is damaged and deformed, it needs to be repaired and corrected by sheet metal. The most commonly use...
