Device for spot welding on wheel housing

Abstract

The invention relates to a device for spot welding on a wheel housing. The device comprises an arc-shaped connecting plate, powerful magnets and a plurality of red copper base plates, and is characterized in that the appearance of the arc-shaped connecting plate which is made of two steel coil binding straps is matched with that of a front wheel housing; the red copper base plates are uniformly distributed on a side surface of the arc-shaped connecting plate; connecting plates on the red copper base plates are fixed on the arc-shaped connecting plate; the powerful magnets (A) are arranged at two ends of the arc-shaped connecting plate; and the powerful magnet (B) is fixed on a positioning connecting plate on the other side surface of the arc-shaped connecting plate. The device is reasonable in design, simple in structure, easy to manufacture and low in cost. Because the appearance of the arc-shaped connecting plate is matched with that of the wheel housing, and the red copper base plates and the powerful magnets are fixedly connected to the arc-shaped connecting plate, the red copper base plates can be accurately and firmly adhered to positions required to be in spot welding under the action of the attraction force of the powerful magnets, the surface of the wheel housing is protected and isolated by using the red copper base plates, an electrode head is not in contact with a spot welding surface directly, the welding quality of the wheel housing can be guaranteed, and the welding efficiency is high.

Description

technical field [0001] The invention relates to the technical field of spot welding of automobiles, in particular to a device for spot welding of wheel covers, which can improve the quality of spot welding surfaces. Background technique [0002] The front wheel cover of the truck adopts a welded structure. After the two processes of painting and assembly, the welding spot here is located in the obvious visible position of the car after the door is opened. The appearance quality has a great influence. In the process of spot welding, when the operator operates the welding tongs, the action direction of the moving electrode should be perpendicular to the spot welding surface. The skew of the welding tongs and the wear of the electrode head will cause defects such as "horseshoe pits" and deep indentations to varying degrees. , the defects caused by spot welding are difficult to eliminate in the subsequent sequence, so the surface quality of spot welding cannot be guaranteed.

In the process of spot welding, when the operator operates the welding tongs, the action direction of the moving electrode should be perpendicular to the spot welding surface. The skew of the welding tongs and the wear of the electrode head will cause defects such as "horseshoe pits" and deep indentations to varying degrees. , the defects caused by spot welding are difficult to eliminate in the subsequent sequence, so the surface quality of spot welding cannot be guaranteed

In this way, the operation requirements of the operator are high, and the labor intensity is increased, and the production efficiency is low.
