Description

Technical Field

[0001] The utility model relates to the technical field of welding installation of welding parts, in particular to a clamping device for welding installation of welding parts. Background Art

[0002] Welding installation of welded parts refers to the process of fixing or connecting welded parts together through welding process. Welding is a manufacturing process and technology that joins metals or other thermoplastic materials by heating, high temperature or high pressure. During the processing, a clamping device is needed to clamp the welded parts. After searching, the patent with announcement number CN219379465U discloses a clamp for welding production. A first clamping device is installed on the device. The first welded part can be fixed and clamped by the provided driving assembly and the first welding clamping assembly. The movable block is driven to move on the threaded rod by the rotation of the motor, and the movable plate is pulled up so that the first welded part is fixed by the first clamping plate, which is convenient for adjusting the distance between them. It is suitable for different types of welding objects. A second clamping device is installed on the device. The clamping device can fix and clamp the second welding part through the sliding component and the second welding clamping component. By sliding the sliding block in the slide plate, the second clamping plate fixes the second welding part so that it can be welded and fixed together with the first welding part and clamped firmly. However, the distance between the welding points of some welding parts is long. Although it can clamp the welding parts, it is necessary to move the welding device when welding the next welding point, which is more inconvenient to operate. For this reason, a clamping device based on welding installation is designed, which is easy to move horizontally after tightening, is convenient for multi-point welding of longer welding parts, and improves the flexibility and convenience of welding installation of welding parts.
