Abstract

The invention discloses a deformation control device, and belongs to the field of welding of automobile bodies. The deformation control device is mounted on a fixture, the fixture comprises a gas circuit, the deformation control device comprises a support frame and at least one sucker, the support frame is fixed onto the fixture, and the suckers are fixed onto the support frame and connected with the gas circuit of the fixture. Gas is supplied to the suckers via the gas circuit of the fixture, so that the suckers can be sucked at deformable positions of plates of an automobile body, the plates of the automobile body are sucked and positioned, the strength of each position which is originally easy to deform under the action of welding stress is improved, deformation of the plates of the automobile body is effectively controlled, the automobile body is effectively prevented from deforming, and field scrapping ratio is effectively reduced. Besides, the deformation control device can effectively control deformation of the automobile body only by sucking and positioning the plates of the automobile body via the suckers, and accordingly the deformation control device is low in cost and short in period.

Description

technical field [0001] The invention relates to the field of automobile body welding, in particular to a deformation control device for controlling the deformation of the automobile body during welding. Background technique [0002] Due to the design structure of the product and the influence of sheet metal stretchability, the car body often deforms during the welding process, which affects the appearance quality of the car body. Specifically, the car body is mostly a cavity structure with a large area, and the sheets constituting the car body are relatively soft. Therefore, the stress generated during welding causes the sheet metal to deform, thereby affecting the appearance of the car body. [0003] At present, the body deformation is mainly avoided by changing the product structure or mold structure and on-site sheet metal repair, but the cost of rectification is high and the cycle is long. Moreover, during the design stage, the body cannot be completely simulated throug...
