Abstract

The invention discloses a measuring tool for rapidly measuring the diameter of a conical inner cavity casing; two plane positioning blocks a and b are fixed at two ends of a body seat, and a measuringrod b is a fixed measuring rod and is arranged at the right side of the body seat; a support is arranged in a cavity of the body seat, a support block is arranged in a cavity of the support, and themeasuring rod a and the measuring rod c are fixed to integrally form a movable measuring rod; a flange linear bearing and a bushing are respectively fixed at two ends of the support; a pull rod is fixed on the support block; a compression spring is arranged on the pull rod; a handle and the pull rod are vertically fixed; a sliding rod is fixed on the support block; two spherical deep groove bearings and two baffle plates arranged on the support slide in a gapless manner; a bracket is arranged on the body seat in the same direction as the movable measuring rod and is fixed with the body seat through welding; and a spring is arranged on the bracket to clamp a measuring meter, and a limiting screw is arranged below the measuring meter. The measuring tool is light in overall weight, convenientand fast to use, capable of improving production efficiency and good in application effect, and has practical application value.

Description

technical field [0001] The invention relates to the technical field of measurement of aero-engine casings, in particular to a measuring instrument for quickly measuring the diameter of a conical inner cavity casing. Background technique [0002] There are many casing parts on the aero-engine, among which there are more conical cavity casings, and the diameter measurement of the casing cavity is indispensable. The original diameter measurement of the horizontal gauge equipped with limit pins has problems such as insensitivity of measurement data, complex tooling structure, and large error in measurement. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a rapid measurement tool for measuring the diameter of the conical inner cavity casing, the specific technical solution is as follows: [0004] A measuring tool for quickly measuring the diameter of a conical inner cavity case, characterized in that i...
