Description

Technical Field

[0001] The utility model relates to the technical field of circuit breaker production, in particular to a clamping tool for welding processing of a circuit breaker frame. Background Art

[0002] The clamping tool plays a vital role in the welding process of the circuit breaker frame. Its main functions are reflected in the following aspects: 1) Ensure welding accuracy: The clamping tool can accurately and reliably position and clamp the various components of the circuit breaker frame to ensure that they maintain the correct relative position and angle during the welding process. This not only reduces the preparatory work before welding, such as marking and alignment, but also improves the accuracy of welding and ensures that the size and shape of the circuit breaker frame meet the design requirements. 2) Improve welding quality: By using the clamping tool, welding deformation can be effectively prevented and reduced. During the welding process, the workpiece is prone to deformation due to thermal stress and mechanical stress. The clamping tool limits the deformation of the workpiece by providing stable support and clamping force, thereby ensuring the quality and strength of the weld. In addition, the clamping tool can also put the workpiece in the best welding position, improve the formability of the weld, reduce process defects, and obtain a satisfactory welded joint. 3) Improve production efficiency: The use of the clamping tool simplifies the welding operation process and reduces the labor intensity of workers. By replacing the heavy work of positioning, clamping and turning the workpiece when assembling parts manually with mechanical devices, the working conditions of workers are improved. At the same time, due to the improvement of welding accuracy and quality, the correction workload and rework rate after welding are reduced, thus improving production efficiency.

[0003] The traditional clamping tooling for welding processing of circuit breaker frames was found to have shortcomings during use. First, after the circuit breaker frame is supported, the circuit breaker frame itself cannot be turned according to the processing requirements, and the circuit breaker frame needs to be frequently installed and disassembled, which is cumbersome to operate; second, after the circuit breaker frame is supported, its height position cannot be adjusted according to the processing requirements. Therefore, it is necessary to optimize and improve the traditional clamping tooling for welding processing of circuit breaker frames. Utility Model Content
