AI Technical Summary

Technical Problem

In mechanical processing, the diameter of the inner hole base surface cannot be measured, resulting in the inflow amount of taper further processing, which brings inconvenience to processing.

Method used

A taper gauge is designed, including a measuring unit and an indicator. By matching settings of the annular reference mark of the lengthening rod and the auxiliary reference mark of the indicator and the deviation scale mark, it is possible to visually display whether the inner hole taper processing is qualified, and the diameter of the inner hole base surface is calculated by reading to determine the further processing amount.

Benefits of technology

It realizes an intuitive judgment on whether the taper processing is qualified, and accurately obtains the adjustable processing volume of taper through calculation, greatly improving the efficiency of taper processing.

Abstract

The utility model provides a taper gauge, and aims to solve the technical problem that the taper processing amount of an inner hole of a conventional part cannot be directly and accurately obtained through the taper gauge, so that much inconvenience is brought. The measuring unit is provided with a gauge and an extension bar. One end of the extension bar is connected in the gauge, and the outer wall of the other end is provided with an annular reference scribed line. The indicator is matched with the large end face of the inner hole of the part and is inserted into the part. And the indicator is sleeved on the outer wall of the extension rod and is movably connected with the extension rod, so that the extension rod reciprocates along the extension direction of the extension rod relative to the indicator. The indicator is provided with an auxiliary reference scribed line. And deviation scale marks are respectively arranged on the left and right sides of the auxiliary reference scribed line and are used for measuring the taper deviation of the inner hole. Through the matching arrangement of the annular reference scale line of the machining rod and the auxiliary reference scale line and the deviation scale line of the indicator, the taper deviation of the inner hole is presented in the form of measuring and reading of the indicator, and a technician can conveniently obtain the adjustment amount of further machining of the taper of the inner hole by calculating the diameter of the base plane of the inner hole.
