Abstract

The invention discloses a variable diameter deep hole inner diameter measuring tool. The measuring tool comprises a positioning connecting module which is used for connecting a to-be-measured workpiece, a measuring displaying module which can be embedded in a deep hole of the to-be-measured workpiece and a moving transmission module which is used for carrying the display module, wherein the movingtransmission module is connected with the positioning connecting module and the measuring displaying module. The displaying module and the moving transmission module are measured by the positioning connecting module, the measuring displaying module is carried to a to-be-measured position of the deep hole of the to-be-measured workpiece by the moving transmission module, and the measuring and displaying of the inner diameter of the to-be-measured position is completed by the measuring displaying module. The electric inner diameter measuring tool has the advantages that a modular structure anda high-precision measuring unit are adopted, and therefore the precision and efficiency of the inner diameter inspecting of a variable diameter deep hole workpiece can be significantly improved.

Description

technical field [0001] The invention discloses an electric inner diameter measuring tool, in particular to a variable diameter deep hole inner diameter measuring tool, which belongs to the technical field of deep hole detection tools. Background technique [0002] At present, the traditional method of measuring the inner diameter of holes mainly uses measuring tools such as calipers and calipers, which are inconvenient to operate, have low measurement efficiency, and are difficult to guarantee accuracy. The existing deep hole or ultra-deep hole internal diameter measuring tools are mainly suitable for the application occasions of equal-diameter deep hole detection. As large and super-large parts are widely used in modern aircraft, ships, large-scale precision instruments and other products, the demand for high-efficiency special measuring tools for variable-diameter deep-hole or ultra-deep-hole parts is becoming more and more urgent. Contents of the invention [0003] The...
