Abstract

The invention discloses a measurer for perpendicularity of the end face to the blind hole axis. An expandable mandrel slides in all directions in a hole according to measurement requirements, the lower end plane of the expandable mandrel, perpendicular to the expandable mandrel axis, butts against a steel ball at the bottom of the blind hole and serving as a measurement datum point, the expandable mandrel contacts with the inner wall of the blind hole through a sliding expanding ball and simulates the blind hole axis, the length of the effective depth of the expandable mandrel inserted into the blind hole is L1, the distance between the expandable mandrel axis and the axis of a dial gage measuring rod is L2, a dial gage measuring head at the left end of the large plane of a transverse plate butts against the end face, and the expandable mandrel rotating for a circle drives a dial gage on the large plane of the transverse plate to measure errors of the perpendicularity of the end face to the blind hole axis. The measurer for perpendicularity of the end face to the blind hole axis is capable of measuring products simply, conveniently, rapidly and accurately, and product quality is guaranteed.

Description

technical field [0001] The invention relates to a measuring device for mechanical parts, in particular to a measuring device for measuring the perpendicularity of an end-to-blind hole axis. Background technique [0002] At present, some mechanical parts are provided with end faces perpendicular to the axis of the blind hole, and the error of the perpendicularity of the end face to the axis of the blind hole directly affects the performance of the mechanical parts. To measure the perpendicularity error of the end-to-face blind hole axis, a flat plate, mandrel, fixed and adjustable supports, and a measuring frame with an indicator are used. The measurement process is complicated and difficult, and it is even more difficult for large parts that are difficult to move. Contents of the invention [0003] The invention provides an end-to-face perpendicularity measurer for the axis of a blind hole. The expandable mandrel slides in various directions in the blind hole according to ...
