Problems solved by technology

The previous welding work was mostly done manually, which was not only time-consuming and labor-intensive, but also had major problems in controlling the quality of the welding points. Automatic welding became the best choice. However, during the automatic welding process, the girder The clamping, how to control the size of the butt joint of the girders, and the positioning of the solder joints are all problems that need to be overcome.

Abstract

The invention provides an overturning clamping device. The overturning clamping device comprises a workbench, front side and rear side clamping mechanisms, a lateral clamping mechanism, first foot support bases and a second foot support base. The front side and rear side clamping mechanisms are installed on the workbench through the first foot support bases. The lateral clamping mechanism is installed on the workbench through the second foot support base. Two sets of the front side and rear side clamping mechanisms are arranged and correspond to the two ends of a part correspondingly. Each set of the front side and rear side clamping mechanisms is composed of two first clamping working sections and two first overturning working sections. The two first clamping working sections of each set of the front side and rear side clamping mechanisms are arranged on the front side and on the rear side of the part correspondingly. The lateral clamping mechanism is arranged by corresponding to the middle of the part and comprises a second clamping working section and a second overturning working section. The overturning clamping device is reasonable in structural design, low in cost, capable of accurately positioning and clamping the part and good in effect through combination of the front side and rear side clamping mechanisms with the lateral clamping mechanism.

Description

technical field [0001] The invention relates to a welding equipment for auto parts, in particular to a turning and clamping device. Background technique [0002] Automobile girder is the main load-bearing part of the truck, which bears almost all the weight of the goods. The quality of the girder affects the service life and driving safety of the vehicle. The stamping process is generally used to manufacture the automobile girder, and its deformation method is mainly bending. Therefore The beam plate has high requirements on formability, that is, the automobile frame steel plate must have good comprehensive properties, sufficient strength and toughness, good fatigue resistance, and cold formability. Therefore, when welding it, the reliability of the welding There are extremely high requirements for precision, dimensional accuracy and the firmness of solder joints. The previous welding work was mostly done manually, which was not only time-consuming and labor-intensive, but ...
