Description

Technical Field

[0001] This utility model relates to a welding positioning device for circuit breaker terminal blocks. Background Technology

[0002] A circuit breaker terminal block welding positioning device is used to ensure the accurate position and stability of terminal blocks during batch welding of circuit breaker terminal blocks. Terminal block welding is a critical step in circuit breaker manufacturing, typically requiring a transmission device to move the terminal blocks from one workstation to another for welding. To improve welding accuracy, traditional circuit breaker terminal block welding positioning devices often use a transmission disc for rotational transmission between workstations, while a supporting device is needed to support the terminal blocks and ensure stable positioning during welding. Existing traditional circuit breaker terminal block welding positioning devices have the following main problems: each workstation usually corresponds to an independent drive device, lacking linkage between multiple workstations. This results in inconsistent action times when welding multiple terminal blocks, compromising accuracy and efficiency, often leading to inaccurate welding and unstable welding quality; the terminal block receiving block is generally fixed on the working transmission disc, and the need for a supporting device during welding poses a certain risk of interference, reducing operational difficulty and safety during the welding process. Therefore, improvements and optimizations are proposed to address these issues. Utility Model Content

The welding positioning assembly is characterized by including a welding positioning seat, a locking plate linkage assembly located on the welding positioning seat, and a locking plate pushing assembly arranged around the arc and corresponding to the terminal block welding receiving blocks.
