Sheet metal part welding device

Abstract

The invention relates to the field of welding dies, in particular to a sheet metal part welding device. The sheet metal part welding device comprises a welding copper plate and a support plate, wherein the copper plate is combined with the sheet metal part when welding, and the support plate is used for placing the welding copper plate. The sheet metal part welding device is characterized by also comprising fixed barrier strips and movable barrier strips for clamping two sides of the welding copper plate, wherein the movable barrier strips can move along a groove on the support plate. The sheet metal part welding device also comprises an upper platen for covering the sheet metal part. The sheet metal part welding device has the beneficial effect that an upper elastic flexible platen pin is arranged between the upper platen and the support plate; the sheet metal parts and the welding copper plates of different thicknesses can be embedded; the barrier strips, the upper platen and the support plate firmly fix the sheet metal part and the welding copper plate, and therefore the sheet metal part and the welding copper plate do not move and dislocate when being welded; the movable barrier strips ensure that the device is used for welding the sheet metal parts of different sizes; and the grid structure of the upper platen divides the welding area into a plurality of independent areas to make welding more stable.

Description

technical field [0001] The present invention relates to the field of welding molds, in particular to a welding device for sheet metal parts. Background technique [0002] In the welding and manufacturing process of automobile body sheet metal parts, it is necessary to add copper plates to protect the surface parts before welding, and at the same time, it is necessary to fix the sheet metal parts and copper plates and make them contact each other. Existing sheet metal parts welding devices usually use clamps to fix the sheet metal parts and copper plates, but the upper and lower distances of the clamps are fixed, so they cannot be used for welding sheet metal parts of different thicknesses; when it is necessary to weld sheet metal parts of different sizes, the sheet metal Parts and copper plates cannot be completely fixed, and movement and misalignment are prone to occur. Contents of the invention [0003] The object of the present invention is to overcome the above proble...
