Description

Technical Field

[0001] This utility model relates to the field of circuit breaker welding technology, specifically to a welding fixture for a double-metal terminal block. Background Technology

[0002] like Figure 8 As shown, when welding the bimetallic terminal block of the circuit breaker, the bimetallic plate 60 needs to be welded to one end of the conductor 61, and the other end of the conductor 61 needs to be welded to the terminal block. The bimetallic plate 60 has a rectangular structure. In the actual mass welding process, there will be dimensional differences between the bimetallic plates 60 after processing. The bimetallic plates 60 are of different lengths and widths. This will cause the bimetallic plates 60 to be too tight, resulting in jamming, or too loose, resulting in swaying when placed in the bimetallic plate fixture. This will have an adverse effect on the accuracy and precision of welding and will greatly reduce the overall welding efficiency. Improvements and optimizations will be made to address this issue.

The length fine-tuning block locking part 16 at the length end of the bimetallic strip 60 and the length fine-tuning block guide protrusion 17 located below the length fine-tuning block locking part 16 are provided. The length fine-tuning block locking part 16 is provided with a length fine-tuning limiting post 18 on its side end. The width fine-tuning block 14 is provided with a width fine-tuning block front end face 19 abutting against the width end of the bimetallic strip 60. The width fine-tuning block front end face 19 is provided with a length travel groove 20 that is opposite to the length fine-tuning limiting post 18 and is used for limiting the travel of the length fine-tuning block 10. The main receiving block 5 is provided with a main receiving block welding port 21 for welding the wire 61 and the bimetallic strip 60. The main receiving block 5 is welded in the main receiving block. The main receiving block 21 has a length positioning groove 22 on its front and rear sides for receiving the bimetallic strip 60 and the length fine-tuning block locking part 16. The main receiving block length positioning groove 22 has a length guide groove 23 that communicates with the welding port 21 of the main receiving block and guides the movement of the length fine-tuning block guide protrusion 17. The length support spring 11 is placed in the length guide groove 23, with one end abutting against the length fine-tuning block 10 and the other end abutting against the end of the length guide groove 23. The main receiving block 5 has a width guide groove 24 that communicates with the length positioning groove 22 and limits the movement of the width fine-tuning block 14. The width support spring 15 is placed in the width guide groove 24. Inside, one end of the length adjustment block 10 abuts against the back of the width adjustment block 14 and the other end abuts against the end of the width guide groove 24. The length support spring 11 and the width support spring 15 are vertically arranged. When the bimetallic strip 60 is placed, the length adjustment block 10 can be flexibly adapted to the different lengths and widths of the bimetallic strip 60 under the action of the length support spring 11 and the width adjustment block 14 under the action of the width support spring 15. This effectively avoids the bimetallic strip 60 from getting stuck or swinging too loosely when placed. The length adjustment block 10 and the width adjustment block 14 are interlocked by the length adjustment limit post 18, which can control the maximum and minimum range of the length adjustment of the bimetallic strip 60 and ensure the stability and reliability of the adjustment action.

[0022] The length positioning groove 22 is higher than the width guide groove 24, and the bottom of the front end face 19 of the width adjustment block is provided with a width adjustment block anti-squeezing groove 25, which ensures that the front end face 19 of the width adjustment block can directly contact the width end of the bimetallic strip 60 and makes the operation of the width adjustment block 14 more reliable.

[0023] The length adjustment assembly 6 further includes a length spring adjustment block 12 and an adjustment screw 13. The length spring adjustment block 12 includes a spring adjustment block receiving part 27 placed on the length positioning groove 22 of the main receiving block and a spring adjustment block limiting part 28 placed in the length guide groove 23. One end of the length support spring 11 abuts against the back of the length fine-tuning block 10 and the other end abuts against the length spring adjustment block 12. The back of the length spring adjustment block 12 is provided with an adjustment block threaded hole 29.

The adjustment screw 13 is threadedly connected to the main receiving block threaded hole 30 and the adjustment block threaded hole 29 in sequence. When the stability of the length support spring 11 decreases due to frequent extension and contraction, the restoring force of the length support spring 11 can be flexibly adjusted by tightening or loosening the adjustment screw 13, making adjustment more convenient and effectively improving welding efficiency and service life.

[0024] The bimetallic strip receiving assembly 3 also includes a pressure plate 8 for preventing the bimetallic strip 60 from moving upward during welding. The main receiving block 5 is provided with a pressure plate limiting port 32 that communicates with the welding port 21 of the main receiving block and is used to limit the movement of the pressure plate 8. The side wall of the welding port 21 of the main receiving block is provided with a pressure plate end receiving groove 33 for receiving the end of the pressure plate 8, which further improves the stability and reliability of welding.
