Embodiment 1
[0049] like Figure 1-2 , a thin-walled rotary body wall thickness difference measuring assembly 9, comprising: a swing arm 15, a lever 21;
[0050] One end of the swing arm 15 is provided with a through hole, the lever 21) is arranged in the through hole, the lever 21 and the swing arm 15 are hingedly connected through the hinge shaft 17, and the lever 21 can rotate around the hinge shaft 17;
[0051] A measuring head 24 is provided on one side of the lever 21 close to the end of the swing arm 15 , and a sensor 28 for measuring the offset of the end of the lever 21 is provided on the other end of the lever 21 .
[0052] The sensor 28 is mounted on the sensor mounting plate 18 .
[0053] In the prior art, a pair of displacement sensors are installed on two brackets of a "C"-shaped bracket, the two sensors are installed symmetrically, the measuring heads are opposite, and the axis where the sensors are located is perpendicular to the brackets. Insert the "C"-shaped bracket eq...
Embodiment 2
[0065] like Figure 3-6 As shown, this embodiment is further limited on the basis of Embodiment 1: as a specific application of a thin-walled revolving body wall thickness difference measuring component, this solution also provides a thin-walled revolving body wall thickness difference detection device, Including a measurement assembly as described in any of the above.
[0066] As a specific application of the thin-walled revolving body wall thickness difference measurement component, a better detection effect can be obtained. The measurement assembly, the two sets of measurement assemblies are mirrored, the swing arms 15 of the two sets of measurement assemblies are parallel to each other, two tension spring hooks 20 are installed on one side of the swing arm 15, and the first tension spring passes between the swing arms 15 11 is connected to the second tension spring 12 .
[0067] The first tension spring 11 is located at the measuring end, and the second tension spring 12...

Abstract
The invention discloses a thin-walled revolving body wall thickness difference measuring assembly and a detecting device. The measuring assembly includes a swing arm and a lever; one end of the swing arm is provided with a through hole, the lever is arranged in the through hole, and the lever is connected to the swing arm. The arms are hingedly connected through a hinge shaft, and the lever can rotate around the hinge shaft; a measuring head is provided on one side of the lever close to the end of the swing arm, and the other end of the lever is provided with a sensor for measuring the offset of the end of the lever. The invention realizes accurate automatic detection of the wall thickness difference of the thin-walled revolving body, solves the problems of accuracy and efficiency of manual measurement, and greatly improves the detection efficiency of the wall thickness difference of the thin-walled revolving body; During the process, the inner and outer walls of the thin-walled revolving body are scratched.
Description
technical field [0001] The invention relates to the technical field of detection, in particular to a thin-walled rotary body wall thickness difference measurement component and a detection device. Background technique [0002] The wall thickness difference is a key indicator reflecting the consistency of the wall thickness of the revolving body. Whether its value is qualified or not is related to the performance of the revolving body. In actual production, it is often necessary to detect the wall thickness difference of the revolving body, such as thin-walled cylinders, perforating ammunition hoods, inner and outer walls of artillery shells, etc. [0003] At present, there are two main ways to measure the wall thickness difference: one is to use the "manual + tooling" method, that is, there are two spherical protrusions on the horizontally placed cantilever beam, the vertices of the protrusions are in a horizontal plane, and the convex The distance between the starting poin...
