A multifunctional testing machine for shell inner diameter and roundness

Abstract

The invention provides a multi-functional detection machine for the inner diameter and roundness of the shell, which relates to the technical field of inner diameter and roundness detection. To solve the problem of deep shells, it is necessary to deepen the depth of the measuring components of the equipment, because the depth of the equipment is deep , the end is prone to deformation, resulting in measurement errors, and when measuring the roundness, it is necessary to compare and calculate the data, and the problem of poor roundness cannot be observed intuitively, including the detection frame body; the detection machine An adjustment mechanism is installed in the middle of the frame body. In the present invention, since the edge of the right end disk surface of the adjustment mechanism is fixedly installed with a ring-shaped roulette, the connecting block is longitudinally provided with a second hinge shaft, and the second hinge shaft is respectively connected with a push plate to the left, so that the connecting block can be pushed. Move to the left, and make the two measuring rulers separate upward and downward respectively, so as to be tangent to the inner wall of the measured pipe body, so as to achieve the purpose of depth measurement.

Description

technical field [0001] The invention relates to the technical field of inner diameter and roundness detection, and more specifically relates to a multifunctional detector for the inner diameter and roundness of a housing. Background technique [0002] Before the casing enters the stator shrink sleeve, pipe expansion is required, and the inner diameter of the expanded pipe semi-finished product is required to be ≦±0.035mm, and the roundness is required to be within the range of ≦±0.1mm. Due to the high requirement of the stator heat sleeve, all shells must be inspected after tube expansion. The current inspection method is to manually pass through the non-going gauge to fit the shell. Whether the inner diameter of the shell is qualified or not, the value of the inner diameter of the shell cannot be quickly and accurately obtained, let alone the roundness value of the shell, so it is impossible to intuitively judge whether the pipe expansion die is worn. [0003] For example,...
