[0017] like Figure 1As shown, the welding device for circuit breaker components of this utility model includes a workbench 1. A positioning seat 2 is provided in the middle of the workbench 1 for placing a workpiece 3. The workpiece 3 includes a lower shell 31 and an upper shell 33. An integrated limiting post 32 is vertically provided inside the lower shell 31. The upper part of the limiting post 32 passes through the limiting hole 34 of the upper shell 33. The lower shell 31, the upper shell 33, and the limiting post 32 are all made of plastic. A positioning groove 21 is machined on the upper part of the positioning seat 2. The lower part of the lower shell 31 is placed in the positioning groove 21. An mounting seat 6 is provided above the positioning seat 2. A pressure block 4 and an electric heating rod 5 are installed at the lower part of the mounting seat 6 in a staggered manner. The electric heating rod 5 is set one-to-one with the limiting post 32. The upper part of the mounting seat 6 is connected to a lifting plate 8 through a positioning rod 7. The upper part of the lifting plate 8 is connected to a cylinder 12. The mounting seat 6 includes a base 61 and an upper cover 62. The junction of the base 61 and the upper cover 62 forms a receiving cavity 6. 3. The accommodating cavity 63 is equipped with a coiled heating wire 51. The base 61 is made of high temperature resistant material. The upper end of the heating rod 5 extends into the accommodating cavity 63 and is fixed with the heating wire 51. The lower part of the heating rod 5 passes through the base 61 and is locked with a nut. The positioning rod 7 adopts a hollow round tube structure and is connected to the accommodating cavity 63. The heating wire 51 has power lines 52 at both ends. The power lines 52 pass through the positioning rod 7 and the lifting plate 8 and are connected to an external power source. In this way, the power lines 52 are neatly bundled and not easy to tangle. The upper part of the pressure block 4 is fixed with a guide post 41. The guide post 41 is fitted with a compression spring 42. The upper part of the guide post 41 extends into the accommodating cavity 63 and is locked with a nut. The cylinder 12 is installed on the upper fixed seat 11. The upper fixed seat 11 is fixed above the worktable 1 through the column 10. The two sides of the lifting plate 8 are in sliding fit with the column 10. The connection between the lifting plate 8 and the column 10 is provided with a flange sleeve 9.

[0018] During operation, the lifting plate 8 moves the mounting base 6 downward as a whole, and the pressure block 4 presses against the upper part of the upper housing 33. The electric heating rod 5 heats and melts the upper end of the limiting post 32, thus fixing the lower housing 31 and the upper housing 33 together.

[0019] This device offers accurate and convenient positioning, enabling welding of multiple points simultaneously, thus significantly improving work efficiency. It also replaces manual operation with a mechanized structure, eliminating safety hazards.

[0020] In practical use, for ease of understanding of this utility model, it will be described in conjunction with the accompanying drawings;

[0021] During operation, the workpiece to be processed is placed in the positioning slot of the positioning seat, with the upper housing positioned above and the upper part of the limiting post extending out of the limiting hole of the upper housing. The cylinder drives the lifting plate to move down along the column as a whole, and the mounting seat moves down synchronously with the lifting plate. The pressure block first contacts the surface of the upper housing and presses the upper housing tightly, and the pressure spring elastically contracts accordingly until the lower end of the electric heating rod approaches the limiting post. After the heating wire is energized, it heats up and conducts heat to the electric heating rod, which heats the upper end of the limiting post. After the limiting post is heated and melted, it forms an integral structure with the limiting hole, thereby forming a fixed connection between the upper and lower housings. After welding is completed, the cylinder drives the lifting plate and the mounting seat to move up and reset as a whole, and the workpiece can be removed.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
