Inspection tool for breaker break-brake half shaft and inspection method thereof

Abstract

The invention discloses an inspection tool for a breaker break-brake half shaft and an inspection method of the inspection tool. The inspection tool comprises a positioning plate (1), the positioning plate (1) is provided with a left side plate (2) and a right side plate (3), wherein the left side plate (2) and the right side plate (3) are in parallel, and the left side plate (2) and the right side plate (3) are vertically installed on the positioning plate (1); the left side plate (1) is provided with a first positioning hole (21) and a second positioning hole (22), wherein the first positioning hole (21) and the second positioning hole (22) are matched with two cylindrical bosses on a manual plastic connecting lever (8); the right side plate (3) is provided with a first positioning groove (4), and a first pin plate (5) is installed in the first positioning groove (4); the positioning plate (1) is further provided with a second positioning groove (6), and a second pin plate (5) is installed in the second positioning groove (6). According to the inspection tool for the breaker break-brake half shaft and the inspection method of the inspection tool, space structure angles of plastic injection parts can be inspected effectively, inspection quality and labor efficiency are improved, and meanwhile, the inspection tool is simple in structure and nimble in operation.

Description

technical field [0001] The present invention relates to a checker for the opening half shaft of a circuit breaker and a detection method thereof, in particular to a checker for checking the angle between the plastic crank arm and the slotting angle of the half shaft of the injection molded part of the opening half shaft of the circuit breaker and its detection method. its detection method. Background technique [0002] The injection molded part of the opening half shaft of the circuit breaker requires the manual plastic crank arm to be perpendicular to the bottom surface of the groove in the middle of the injection molded part of the opening half shaft, so that the brake can be reliably opened. However, in actual work, in view of the structure of the bottom surface of the groove in the middle of the manual plastic crank arm and the injection molded part of the opening half shaft, it is impossible to use an angle ruler and a projector to measure the injection molded part of t...

AI Technical Summary

Problems solved by technology

However, in actual work, in view of the structure of the bottom surface of the groove in the middle of the manual plastic crank arm and the injection molded part of the opening half shaft, it is impossible to use an angle ruler and a projector to measure the injection molded part of the opening half shaft, and it can only be measured visually

However, the error of visual measurement results is very large, and the product quality cannot be guaranteed, which seriously affects the normal use requirements.
