Problems solved by technology

[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

Embodiment Construction

[0017] Such as figure 2 As shown, a trapezoidal copper bar inspection gauge for steering gear, the left gauge 1 and the right gauge 2 have a height difference H, the inspection gauge 6 has symmetrical slopes on both sides, the angle of the slope is α, and the angle of the slope c of the left gauge 1 is α / 2, the angle of the slope d of the right gauge 2 is α / 2, such as image 3 As shown, the slope c side of the left gauge 1 is attached to the left slope e of the inspection gauge 6, and the slope d side of the right gauge 2 is attached to the right slope f. The inspection gauge 6 is composed of the straight side dimension A and the symmetrical slope angle α. There is an upper engraved line n on both sides of the straight side with dimension A, and the position of the upper engraved line n is at the intersection of the straight side with dimension A and the symmetrical slope of angle α, and the two sides of the symmetrical slope with angle α have lower engraved line m, The dis...

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
