[0003] In the existing technology, there are some shortcomings in the assembly of the circuit breaker center base and accessories. The traditional assembly method often relies on manual operation and lacks precise positioning fixtures. As a result, the left and right accessories are easily installed reversely during the assembly process, which requires them to be disassembled and reassembled. This leads to low assembly efficiency, making it difficult to meet the needs of large-scale production, and increasing production costs and production cycles.

[0004] Furthermore, the positioning cones of existing assembly tools are fixed and cannot be adjusted to accommodate different accessory models. This results in existing assembly fixtures being unable to flexibly adapt to the diverse accessory models during assembly. Multiple fixtures of varying specifications are often required to meet assembly requirements, increasing costs and reducing work efficiency.

[0005] When assembling a smaller accessory, the positioning cone cannot be adjusted, making it difficult to align the accessory accurately, affecting assembly precision and quality. Larger accessories may not even fit on the fixture for assembly, leading to shaking and instability during assembly, increasing operational difficulty and safety risks.

[0006] The existence of these problems makes the assembly of the circuit breaker center base and accessories a bottleneck in the production process, restricting the improvement of product quality and production efficiency. Therefore, we have made improvements to this and proposed an assembly fixture for the circuit breaker center base and accessories. Utility Model Content

[0029] Example 1: Please refer to Figure 1-Figure 7 A fixture for assembling a circuit breaker center base and accessories includes a fixture workbench 1. A circuit breaker center base positioning frame 2 is provided above the fixture workbench 1. A positioning cone mounting seat 21 is provided on the circuit breaker center base positioning frame 2. An accessory positioning cone 3 is provided above the positioning cone mounting seat 21. The accessory positioning cone 3 matches the position of the accessory positioning hole 4, and the accessory positioning hole 4 corresponds to the position of the circuit breaker center base through hole 5. The positioning cone mounting seat 21 is provided with a left positioning cone mounting seat 211 and a right positioning cone mounting seat 212. The accessory positioning cone 3 is provided with a left accessory positioning cone 31 and a right accessory positioning cone 32. The left accessory positioning cone 31 is mounted and fixed on the left positioning cone mounting seat 211, and the right accessory positioning cone 32 is mounted and fixed on the right positioning cone mounting seat 212.

[0030] The accessory positioning holes 4 include a left accessory positioning hole 41 and a right accessory positioning hole 42 . The left accessory positioning hole 41 is located above the left accessory positioning cone 31 , and the right accessory positioning hole 42 is located above the right accessory positioning cone 32 .

[0031] The circuit breaker center base through hole 5 includes a circuit breaker center base left through hole 51 and a circuit breaker center base right through hole 52 . The circuit breaker center base left through hole 51 coincides with the circular shape of the left accessory positioning hole 41 , and the circuit breaker center base right through hole 52 coincides with the circular shape of the right accessory positioning hole 42 .

[0032] The left positioning cone mounting seat 211 and the right positioning cone mounting seat 212 are slidably arranged in the positioning cone sliding adjustment slot 6 and fixed by fastening bolts 7. The diameter of the accessory positioning cone 3 is smaller than the diameter of the accessory positioning hole 4. A support rod 8 is provided below the fixture workbench 1.

[0033] The working principle of the assembly fixture for the circuit breaker center base and accessories: First, place the circuit breaker center base on the circuit breaker center base positioning bracket 2 above the fixture workbench 1 to provide stable support and positioning. Then, by sliding the left and right positioning cone mounting seats 211 and 212 in the positioning cone sliding adjustment slots 6 and securing them with fastening bolts 7, the positions of the left and right accessory positioning cones 31 and 32 are adjusted to correspond with the positions of the left and right through-holes 51 and 52 on the circuit breaker center base.

[0034] Once the position is adjusted, place the accessory on the circuit breaker center base. At this point, the left accessory positioning cone 31 mates with the left accessory positioning hole 41, and the right accessory positioning cone 32 mates with the right accessory positioning hole 42. Because the diameter of the accessory positioning cone 3 is smaller than that of the accessory positioning hole 4, the accessory can be easily inserted into the accessory positioning cone 3, achieving initial positioning of the accessory.

[0035] The accessory positioning holes 4 correspond to the positions of the left and right through-holes 51 and 52 of the circuit breaker center, respectively. The left through-hole 51 of the circuit breaker center coincides with the circular shape of the left accessory positioning hole 41, while the right through-hole 52 of the circuit breaker center coincides with the circular shape of the right accessory positioning hole 42. Thus, the interaction between the accessory positioning cone 3, the accessory positioning holes 4, and the through-holes 5 of the circuit breaker center allows for precise assembly of the circuit breaker center and accessories.

[0036] Example 2: A fixture for assembling a circuit breaker base and accessories. The circuit breaker base is placed on a base positioning bracket 2 above the fixture workbench 1 to ensure stable placement. The fastening bolts 7 of the left and right positioning cone mounting seats 211 and 212 are loosened. Based on the actual size of the circuit breaker base, the left and right positioning cone mounting seats 211 and 212 are slid within the positioning cone sliding adjustment slots 6 to align the left and right accessory positioning cones 31 and 32 with the left and right through-holes 51 and 52 of the circuit breaker base, respectively.

[0037] After adjusting the positions of the left positioning cone mounting seat 211 and the right positioning cone mounting seat 212 , tighten the fastening bolts 7 to fix them in the positioning cone sliding adjustment groove 6 .

[0038] Place the accessory over the left and right accessory positioning holes 41 and 42, respectively. Because the diameter of the accessory positioning cone 3 is smaller than that of the accessory positioning hole 4, the accessory fits smoothly over the cone 3, achieving precise positioning. At this point, the accessory is accurately aligned with the circuit breaker center, and assembly can proceed.

[0039] Example 3: An assembly fixture for a circuit breaker center base and accessories. The fixture workbench 1 is placed on a stable workbench through the support rod 8 below to ensure that the fixture workbench 1 is stable.

[0040] Place the circuit breaker center seat on the circuit breaker center seat positioning frame 2 so that the positions of the circuit breaker center seat through hole 5 and the accessory positioning hole 4 are roughly aligned.

[0041] According to the specific specifications of the circuit breaker center seat, fine-tune the positions of the left positioning cone mounting seat 211 and the right positioning cone mounting seat 212 in the positioning cone sliding adjustment slot 6 to ensure that the left accessory positioning cone 31 is accurately inserted into the left accessory positioning hole 41 corresponding to the left through hole 51 of the circuit breaker center seat, and the right accessory positioning cone 32 is accurately inserted into the right accessory positioning hole 42 corresponding to the right through hole 52 of the circuit breaker center seat.

[0042] After confirming that the accessory positioning cone 3 is fully matched with the accessory positioning hole 4, tighten the fastening bolts 7 of the left positioning cone mounting seat 211 and the right positioning cone mounting seat 212 to fix them in the current position.

[0043] Place the accessories to be assembled on the left accessory positioning cone 31 and the right accessory positioning cone 32 respectively. Since the position of the accessory positioning cone 3 matches the position of the accessory positioning hole 4, the accessories will be accurately located above the through hole 5 of the circuit breaker center, which is convenient for subsequent assembly work.

[0044] Specific work flow of the assembly fixture of the circuit breaker center seat and accessories: Preparation: Make sure that the fixture workbench 1 is placed on a stable work surface, and the support rod 8 below plays a role of stable support.

[0045] Adjust the position of the positioning cone mounting seat 21: Loosen the fastening bolts 7 and slide the left positioning cone mounting seat 211 and the right positioning cone mounting seat 212 in the positioning cone sliding adjustment slot 6 according to the specifications and requirements of the circuit breaker center seat. After adjusting to the appropriate position, tighten the fastening bolts 7 to secure the left positioning cone mounting seat 211 and the right positioning cone mounting seat 212 in the positioning cone sliding adjustment slot 6.

[0046] Placing the circuit breaker middle seat: Place the circuit breaker middle seat on the circuit breaker middle seat positioning frame 2 above the fixture workbench 1 so that the circuit breaker middle seat is stably supported and positioned.

[0047] Place the accessories: Place the accessories on the circuit breaker center seat, aligning the left accessory positioning hole 41 with the left accessory positioning cone 31 , and the right accessory positioning hole 42 with the right accessory positioning cone 32 .

[0048] Since the diameter of the accessory positioning cone 3 is smaller than the diameter of the accessory positioning hole 4 , the accessory can be easily put on the accessory positioning cone 3 to achieve preliminary positioning of the accessory.

[0049] Assembly completion: After the accessory is initially positioned by the accessory positioning cone 3, the left through hole 51 of the circuit breaker center base coincides with the circular shape of the left accessory positioning hole 41, and the right through hole 52 of the circuit breaker center base coincides with the circular shape of the right accessory positioning hole 42. At this time, the accessory can be smoothly assembled with the circuit breaker center base, completing the entire assembly process.
