Problems solved by technology

[0003] The clamping device commonly used in the industry is generally inaccurate in positioning, which is easy to cause welding deformation, and post-weld deformation treatment is required
Even if it can be positioned accurately, the structure design of the general device is relatively complicated
In this way, it not only makes the technological process more complicated, but also increases the time and procedures of the whole welding process, and greatly wastes the cost.

Abstract

A welding device includes a base plate and a pressing device fixed on the base plate. The pressing device includes a bracket, and a pressing plate fixed on the bracket is rotatable. The pressing device also includes a power mechanism for pushing the pressing plate to rotate, a supporting mechanism for supporting the welding workpiece, and a rotating part for connecting the bracket and the pressing plate in rotation. The power mechanism is fixed on the bracket, and the power mechanism includes a power part, a guide post, and a guide sleeve. The guide sleeve is provided with a first through hole, and the guide column can slide in the guide sleeve through the first through hole. One end of the guide post abuts against one end of the pressure plate, and the other end of the guide post abuts against one end of the power part. The power mechanism pushes the guide column to move up and down, the guide column presses the pressure plate to rotate around the rotating part, and the other end of the pressure plate presses the welding workpiece between the other end of the pressure plate and the supporting mechanism. The above-mentioned welding equipment compresses the welding workpiece through the pressing device, so as to prevent the welding workpiece from moving during the welding process and ensure the accuracy of the welding position.

Description

technical field [0001] The invention relates to a pressing device, in particular to a welding device with the pressing device. Background technique [0002] In the mechanical field, it is often necessary to weld workpieces. First of all, the welding workpiece needs to be positioned to ensure the accuracy of the welding position. Then, the welding process is performed. However, due to the large size of the welding workpiece, there is a phenomenon that positioning is difficult. Inaccurate positioning will cause the welding workpiece to move during the welding process, causing the welding position to shift and affecting the welding effect. Moreover, during the welding process, due to the uneven heating of the welded workpiece as a whole, the welded workpiece is prone to local deformation, so it is necessary to accurately and stably fix the welded workpiece. [0003] The clamping devices commonly used in the industry are generally inaccurate in positioning, which can easily ...
