Abstract

The invention provides an apparatus for measuring the wall thickness of a circular housing. The apparatus comprises a pedestal, a rotary bench which is used for bearing a housing to be measured and is rotatable about self central axis, a post which is arranged on the pedestal and configured to be rotatably connected the pedestal at a first position, and an angle adjusting mechanism which is configured to adjust the angle of the column relative to the pedestal. One end of the angle adjusting mechanism is connected to the post, and the other end is connected to the pedestal at a second position. A first measuring arm and a second measuring arm, which can move along the longitudinal directions of the post, are arranged on the post, are equal in length and are provided with two range finding modules. An indirect measuring method is employed for measuring wall thickness. The apparatus allows automatic measuring the wall thickness of circular housings, the measuring accuracy and measuring efficiency are higher, and measuring blind areas are effectively minimized.

Description

technical field [0001] The invention relates to the technical field of measuring equipment, in particular to a wall thickness measuring device and a measuring method with a cylindrical or conical shell. Background technique [0002] In aerospace, machinery and other manufacturing fields, the processing and manufacturing of circular shells is relatively extensive, involving processes such as casting, sheet metal and finishing. In order to make the shell have strong rigidity, light weight and good machinability, it is necessary to measure the wall thickness of the shell and control it within a certain tolerance range. [0003] At present, operators mainly use ultrasonic thickness gauges to measure the shell wall thickness point by point. During the measurement process, it is necessary to continuously dip and apply couplant, the measurement efficiency is low, and the measurement results of different personnel are quite different. At the same time, due to the limited number of ...
