Assembling tool for nozzle of breaker and positioning assembly of assembling tool

Abstract

The invention relates to an assembling tool for a nozzle of a breaker and a positioning assembly of the assembling tool. The assembling tool comprises a gear frame, wherein the gear frame is used for being arranged on the periphery of the corresponding nozzle in a sleeved mode and is matched with the nozzle through the positioning assembly in a rotation stopping mode when used. The lower end of the gear frame is provided with a left pin channel and a right pin channel which correspond to two radial installation holes in the nozzle respectively. The positioning assembly comprises a left positioning pin and a right positioning pin, the left positioning pin and the right positioning pin are used for being inserted in the two radial installation holes in the nozzle in a positioning mode respectively, the left positioning pin and the right positioning pin are correspondingly installed on a first support and a second support respectively, and an elastic retaining structure which enables the left positioning pin and the right positioning pin to be retained in the corresponding pin channels and the corresponding radial installation holes respectively is arranged between the first support and the second support. The positioning assembly enables the gear frame and the nozzle to be positioned firmly and is used in the assembling tool for the nozzle of the breaker.

Description

technical field [0001] The invention relates to an assembly tool for a circuit breaker spout and a positioning assembly thereof. Background technique [0002] When assembling the circuit breaker in the workshop, the corresponding nozzle needs to be screwed on the circuit breaker. To this end, torque needs to be applied to the nozzle. Two radial mounting holes for torque input are symmetrically arranged on the nozzle. At present, there is a lack of corresponding special torque. Tightening tools, previously used temporary tools, cut two bolt holes corresponding to the radial installation holes on a transmission frame, and then through the bolt holes and the corresponding radial installation holes in the form of piercing bolts The transmission frame is engaged with the spout to prevent rotation, and then torque is applied to the spout by applying torque to the transmission frame. The existing temporary tool has the following problems: 1. After the bolt holes on the transmissio...

AI Technical Summary

Problems solved by technology

The existing temporary tools have the following problems: 1. After the bolt perforations on the drive frame correspond to the radial mounting holes respectively, the bolts can be worn in the bolt perforations and the corresponding radial mounting holes. The alignment process of the spout is very troublesome, and often requires one person to hold the drive frame for alignment, and another person to install the bolts after alignment, and it requires the cooperation of multiple people to complete the assembly of the drive frame and the spout; 2. The spout on the spout The radial mounting hole is a light hole structure. After the bolt is installed in the radial mounting hole, due to the lack of corresponding limit structure, the bolt is easy to come out of the radial mounting hole and scratch the workpiece. Sliding down and injuring the operator
