Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of circuit breaker production equipment, and particularly relates to a positioning structure for plastic shell circuit breaker production. BACKGROUND

[0002] The positioning structure for plastic shell circuit breaker production refers to a series of structural components designed to ensure that each component can be accurately and firmly assembled at the predetermined position during the production and manufacturing process of the plastic shell circuit breaker. These positioning structures play a crucial role in the assembly, testing, and subsequent use of the circuit breaker.

[0003] The application number "CN202321716794.2" describes a positioning structure for plastic shell circuit breaker production, which includes a base and an L-shaped mounting bracket. The L-shaped mounting bracket is fixed to the base, and a horizontal bar is fixedly installed at one end of the L-shaped mounting bracket. A horizontal installation slot is formed in the horizontal bar, and a bidirectional drive assembly is installed in the horizontal installation slot. A serpentine connecting rod is installed on the bidirectional drive assembly, and a U-shaped positioning seat is installed on the serpentine connecting rod. The U-shaped positioning seat is fixedly connected to one end of the serpentine connecting rod through a self-locking angle positioning assembly.

[0004] The above-mentioned patent can clamp and fix circuit breakers of different sizes, adjust the angle of the U-shaped positioning seat, and fix the U-shaped positioning seat after the angle adjustment is completed. This allows the positioning and fixing of circuit breakers at different angles, facilitating the assembly and production of circuit breakers and providing flexible use. However, the clamping equipment for long-term clamping of circuit breakers cannot be disassembled, repaired, or replaced, which can easily cause the circuit breakers to loosen during processing, thereby reducing the overall processing efficiency and precision of the device. Moreover, the above-mentioned patent can clamp and fix circuit breakers of different sizes, but it is limited to circuit breakers of different widths and does not provide clamping and fixing for circuit breakers of different heights, resulting in imperfect overall clamping and fixing optimization of the device.
