Steering gear trapezoidal copper bar detection gauge

Abstract

The invention relates to a steering gear trapezoidal copper bar detection gauge. The steering gear trapezoidal copper bar detection gauge is characterized in that an inspection gauge, a left gauge anda right gauge are combined together for measurement, a comparative measurement method is adopted for calibrating the left gauge, the right gauge and the inspection gauge, the dimensions of the inspection gauge are strictly designed according to a dimensional tolerance range of a steering gear trapezoidal copper bar, and the steering gear trapezoidal copper bar can be measured after confirming that the upper planes of the left gauge and the right gauge coincide with graduated lines on the inspection gauge, and the steering gear trapezoidal copper bar between the upper planes of the left gaugeand the right gauge is regarded as a qualified product, otherwise, regarding the steering gear trapezoidal copper bar as an unqualified product. The steering gear trapezoidal copper bar detection gauge is a convenient, quick and precise measuring tool, shortens the measurement time, and provides a combined detection tool for combined production.

Description

Technical field: [0001] The invention relates to a detection gauge for a trapezoidal copper bar of a steering gear, which is used in the field of measuring the trapezoidal copper bar of a steering gear. Background technique: [0002] Such as figure 1 As shown, a large number of steering gear trapezoidal copper bars are required in large motors. The manufacturing precision of the steering gear trapezoidal copper bars is very high, and each size is a must-check item. The slope angle of the steering gear trapezoidal copper bars cannot be detected with ordinary inspection tools. In the past, the combination of micrometer and ball micrometer was used to directly measure the size of the big end, and the angle of the trapezoidal copper bar was calculated by importing the formula. The advantage of this measurement method is that the measured value is accurate, but the disadvantage is that the efficiency is too low and the measurement speed Too slow, each motor needs a large number ...

[0002] like figure 1 As shown, a large number of steering gear trapezoidal copper bars are required in large motors. The manufacturing precision of the steering gear trapezoidal copper bars is very high, and each size is a must-check item. The slope angle of the steering gear trapezoidal copper bars cannot be detected with ordinary inspection tools. In the past, the combination of micrometer and ball micrometer was used to directly measure the size of the big end, and the angle of the trapezoidal copper bar was calculated by importing the formula. The advantage of this measurement method is that the measured value is accurate, but the disadvantage is that the efficiency is too low and the measurement speed Too slow, each motor needs a large number of steering gear trapezoidal copper bars, and each trapezoidal copper bar must be measured, using this method to measure the workload is very large
