[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments: like Figure 1-3As shown, a hole-positioning fixture for a circuit breaker housing includes a workbench 1 and multiple positioning blocks 2. The multiple positioning blocks 2 are respectively disposed on the workbench 1, and a positioning clamping space 100 for placing the circuit breaker housing is formed between the workbench 1 and the positioning blocks 2. Multiple first limiting rods 3 and multiple second limiting rods 4 are detachably connected to the positioning clamping space 100 on the workbench 1. The multiple first limiting rods 3 are used to pass through the pivot hole of the circuit breaker housing, and the multiple second limiting rods 4 are used to pass through the rivet hole of the circuit breaker housing. A push rod 5 is slidably disposed on each positioning block 2. One end of the push rod 5 has a limiting part 51 for passing through the side hole of the circuit breaker housing, and the other end of the push rod 5 has a pushing part 52 exposed outside the positioning block 2.

[0021] like Figure 2-4As shown, multiple positioning blocks 2 are slidably mounted on the worktable 1. The worktable 1 is equipped with multiple sets of adjustment components 6 for adjusting the positions of the positioning blocks 2. These adjustment components move the positioning blocks 2 to adjust the size of the positioning clamping space 100. The multiple adjustment components can adjust the positions of the positioning blocks, allowing for adjustment of the positioning clamping space size according to different specifications of circuit breaker housings, thus improving the versatility of this hole-position tooling fixture. Each positioning block 2 has a guide protrusion 21, and the worktable 1 is provided with an adjustment hole 11 for the guide protrusion 21 to slide. The positioning block 2 drives the guide protrusion 21 to reciprocate within the adjustment hole 11. The positioning block is slidably mounted within the guide hole of the worktable via the guide protrusion, ensuring reliable sliding of the positioning block on the worktable. Each adjustment assembly 6 includes an adjustment rack 61 and a locking bolt 62 mounted on the worktable 1. The worktable 1 has a sliding hole 12 communicating with the adjustment hole 11. The adjustment rack 61 is slidably mounted within the sliding hole 12 and drives the positioning block 2 to move within the adjustment hole 11. One end of the locking bolt 62 extends into the sliding hole 12 and abuts against the adjustment teeth 611 of the adjustment rack 61. By tightening the locking bolt against the adjustment teeth of the adjustment rack, the position of the positioning block can be easily adjusted, making operation convenient. One end of the adjustment rack 61 has a driving part 612 that passes through the sliding hole 12 and abuts against the positioning block 2, and the other end of the adjustment rack 61 has a handle part 613 protruding outside the sliding hole 12. By pulling the handle part, the position of the adjustment rack can be adjusted. The driving part of the adjustment rack abuts against the positioning block, ensuring that the adjustment rack can reliably drive the positioning block to move reliably on the worktable. The drive unit 612 is provided with a positioning groove 6121, and a buffer spring 63 is provided in the positioning groove 6121. One end of the buffer spring 63 abuts against the positioning block 2. A buffer spring is provided between the adjusting racks.

[0022] like Figure 1 and 4As shown, the workbench 1 has multiple first insertion holes 13 and multiple second insertion holes 14 corresponding to multiple first limiting rods 3 and multiple second limiting rods 4. One end of each of the multiple first limiting rods 3 and multiple second limiting rods 4 has multiple first insertion parts 31 and multiple second insertion parts 41 that pass through the multiple first insertion holes 13 and multiple second insertion holes 14. The multiple first limiting rods and multiple second limiting rods are respectively inserted into the workbench, facilitating the assembly of the first limiting rods and second limiting rods with the workbench. When inspecting hole positions, the positions of the first limiting rods and second limiting rods can be adjusted according to different specifications of circuit breaker housings, thus improving the versatility of the hole position tooling. On the workbench 1, corresponding to multiple first insertion holes 13 and multiple second insertion holes 14, multiple first indicator marks 15 and multiple second indicator marks 16 are respectively provided. At the other end of multiple first limiting rods 3 and multiple second limiting rods 4, multiple first limiting marks 32 and multiple second limiting marks 42 are respectively provided, matching the multiple first indicator marks 15 and multiple second indicator marks 16. The presence of first and second indicator marks on the workbench, corresponding to the first and second limiting rods, prevents incorrect installation of the first and second limiting rods, thereby improving assembly efficiency.

[0023] Multiple first and second limit rods are respectively set on the worktable. These rods can pass through the shaft holes and rivet holes of the circuit breaker housing. The positioning clamping space of multiple positioning blocks provides positioning for the circuit breaker housing. During testing, simply placing the circuit breaker housing into the positioning clamping space allows for the detection of the hole positions on the circuit breaker housing, making operation convenient and cost-effective. Furthermore, the adjustment assembly can adjust the positions of multiple positioning blocks, thus adapting to circuit breaker housings of different specifications and improving versatility.
