Multifunctional detection machine for inner diameter and roundness of housing

Abstract

The invention provides a multifunctional detection machine for inner diameter and roundness of a housing, relates to the technical field of inner diameter and roundness detection, and is to solve theproblems that since a measurement component of equipment needs to be deeply inserted into a housing with a large depth, measurement errors are generated due to the fact that the equipment is deeply inserted and the end is prone to deformation, and besides, comparison calculation needs to be conducted on data during roundness measurement, and roundness difference cannot be visually observed. The multifunctional detection machine comprises a detection machine rack body. An adjusting mechanism is mounted in the middle of the detection machine rack body. An annular wheel disc is fixedly mounted atthe edge of the right end disc surface of the adjusting mechanism; a connecting block is longitudinally provided with a second hinge shaft; the second hinge shaft is connected with a push plate leftwards, and the push plate can push the connecting block to move leftwards; and two measuring rulers are separated upwards and downwards respectively to be tangent to the inner wall of a measured pipe body, and thus the purpose of deep diameter measurement is achieved.

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,...

Problems solved by technology

[0005] The invention provides a multi-function detector for the inner diameter and roundness of the shell, in order to solve the deep shell, 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 The measurement error occurs, and the data needs to be compared and calculated when measuring the roundness, and the problem of roundness difference cannot be observed intuitively
