A molded case circuit breaker installation equipment

Abstract

The invention relates to a molded case circuit breaker installation device. The device comprises a clamping seat and a supporting seat, wherein clamping grooves are formed in the bottom surface of the clamping seat and the top surface of the supporting seat; the clamping groove are used for clamping a circuit breaker, and a pushing cylinder is arranged on the top surface of the clamping seat; the pushing cylinder is fixed on a transverse plate; a positioning buffer mechanism is arranged between the clamping seat and the supporting seat; a guide sleeve is arranged on the top surface of the clamping seat, the top end of the guide sleeve adopts a conical structure, the bottom end of the conical structure adopts circular arc transition, and the guide sleeve is used for guiding an electric screwdriver; a rotary supporting mechanism is arranged in the guide sleeve, and a protection mechanism and a supporting mechanism are arranged at the bottom in the guide sleeve. The device avoids the screw driving deflection, protects the shell of the circuit breaker, and eliminates the safety risk; the device achieves the buffering of an electric screw driver, and also has a limiting function; the device avoids the screw thread slipping when the electric screw driver is pressed too much, thereby protecting the shell of the circuit breaker, and reducing the production cost.

Description

technical field [0001] The invention relates to the technical field of circuit breaker installation, in particular to a molded case circuit breaker installation device. Background technique [0002] The molded case circuit breaker can automatically cut off the current after the current exceeds the trip setting. Molded case refers to the use of plastic insulators as the casing of the device to isolate conductors and grounded metal parts. The shell of the molded case circuit breaker is connected by screws by the upper shell and the lower shell to protect the original circuit breaker inside. [0003] When installing the shell of the molded case circuit breaker, it is necessary to use an electric screwdriver to tighten the screws between the upper shell and the lower shell. This requires the use of molded case circuit breakers to install equipment. However, the current installation equipment for molded case circuit breakers has the following disadvantages: 1. During the use o...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a molded case circuit breaker installation device, which can solve the problem that the above-mentioned electric screwdriver cannot ensure that it is completely parallel to the screw hole during use, causing the screw to be deflected, and in severe cases, the circuit breaker is damaged. There is a safety risk in the outer casing; traditional installation equipment cannot cushion the electric screwdriver, and there is no limit function. When the electric screwdriver is pressed too hard, it is easy to cause the screw to slip, damage the outer casing of the circuit breaker, and improve production. cost conundrum
