[0023] Example

[0024] Please refer to Figures 1-4 This embodiment provides an auxiliary tooling for welding the inside of a pole-mounted circuit breaker housing 10, used to assist in positioning the pole-mounted circuit breaker housing 10 and the reinforcing plate 11 during welding. It includes a workbench for welding operations. Specifically, the workbench includes a working panel 1 and a support frame 2. The working panel 1 is mounted on the support frame 2, and a limiting platform for positioning the housing shell is provided on the working panel 1. The working panel 1 is used to place the pole-mounted circuit breaker housing 10 to be welded. The support frame 2 is used to lift the working panel 1, allowing the user to stand and operate, improving the convenience and comfort of the operation. The limiting platform is used to initially limit the position of the pole-mounted circuit breaker housing 10 to be welded, that is, to position the pole-mounted circuit breaker to be welded laterally and longitudinally on the working panel 1.

[0025] A positioning mechanism for positioning the enclosure and the workpiece to be welded includes a lifting base 5, a mounting beam 6, and positioning components. The lifting base 5 is mounted on the work panel 1, and the mounting beam 6 is located at the end of the lifting base 5 away from the work panel 1. Three positioning components are evenly spaced on the mounting beam 6. Specifically, the lifting base 5 is vertically fixed to the work panel and is used to suspend the mounting beam 6 and the positioning components directly above the workpiece to be welded. The mounting beam 6 is used to install and fix the positioning components. The three positioning components are evenly spaced on the mounting beam 6 and are used to cooperate with the reinforcing plate 11 and the three-phase components of the pole-mounted circuit breaker enclosure 10. The positioning components are used to position the pole-mounted circuit breaker enclosure 10 and the reinforcing plate 11 to be welded perpendicular to the work panel 1.

[0026] Specifically, the aforementioned positioning components include a drive element 7, a push plate 8, and a positioning pin 9. A lifting base 5 is mounted on the work panel 1, a mounting beam 6 is mounted on the lifting base 5, the drive element 7 is mounted on the lifting base 5, and the push plate 8 is located at the output end of the drive element 7. The drive element 7 is used to push the push plate 8 against the surface of the workpiece to be welded. The positioning pin 9 is located on the push plate 8 and passes through the mounting hole 13 on the housing, which is used to accommodate bolts. The drive element 7 is used to push the push plate 8 against the upper surface of the reinforcing plate 11, and to push the reinforcing plate 11 against the pole-mounted circuit breaker housing 10. Simultaneously, the positioning pin 9 on the push plate 8 is inserted sequentially into the through hole 12 of the reinforcing plate 11 and the mounting hole 13 of the pole-mounted circuit breaker. During welding, this effectively corrects the misalignment of the through hole 12 of the reinforcing plate 11 and the mounting hole 13 of the pole-mounted circuit breaker housing 10 caused by thermal deformation during welding, effectively reducing the defect rate of the equipment.

[0027] Please refer to Figure 1 In some embodiments of this example, the limiting platform includes a transverse limiting plate 3 and a longitudinal limiting plate 4, with the transverse limiting plate 3 perpendicular to the longitudinal limiting plate 4.

[0028] In this embodiment, the transverse limiting plate 3 and the longitudinal limiting plate 4 are used to quickly position the side wall of the box to be welded, so that the pole-mounted circuit breaker box 10 to be welded is directly below the positioning mechanism, which facilitates subsequent welding operations.

[0029] Please refer to Figure 1 In some embodiments of this example, the transverse limiting plate 3 and the longitudinal limiting plate 4 are integrally formed.

[0030] In this embodiment, the transverse limiting plate 3 and the longitudinal limiting plate 4 are manufactured using an integral molding process. The included angle between the transverse limiting plate 3 and the longitudinal limiting plate 4 is 90°, which facilitates quick bidirectional positioning with the corners of the box.

[0031] Please refer to Figures 1-3 In some embodiments of this example, the driving element 7 is a cylinder, and the push plate 8 is disposed at the output end of the cylinder.

[0032] It should be noted that a cylinder is a cylindrical metal component that guides the piston in linear reciprocating motion within the cylinder. In an engine cylinder, air expands, converting thermal energy into mechanical energy; in a compressor cylinder, gas is compressed by the piston, increasing its pressure. The push plate 8 is reciprocated via a pneumatic rod, facilitating the placement of the reinforcing plate 11 against the pole-mounted circuit breaker housing 10 before welding, thus preventing gaps during welding and improving the precision of the welded product.

[0033] In use, the pole-mounted circuit breaker housing 10 to be welded is pushed onto the limiting platform. The transverse outer wall and longitudinal outer wall of the pole-mounted circuit breaker housing 10 abut against the transverse limiting plate 3 and the longitudinal limiting plate 4, respectively. The reinforcing plate 11 is removed, and the central axis of the through hole 12 of the reinforcing plate 11 and the central axis of the mounting hole 13 of the pole-mounted circuit breaker housing 10 are kept aligned. The cylinder is driven to push the push plate 8 onto the upper surface of the reinforcing plate 11. The positioning pin 9 is inserted into the through hole 12 of the reinforcing plate 11 and the mounting hole 13 of the pole-mounted circuit breaker housing 10 in sequence. Finally, the welding operation is performed.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
