Problems solved by technology
The whole detection process takes a long time, the speed is slow, and the measurement data is not very accurate. What is more cumbersome is that calculation and analysis are required after the data measurement, which is very troublesome to operate and the effect is not high.

Embodiment Construction
[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0018] As shown in the figure, the concentricity detector of the stator gear of the iron frozen motor casing relative to the shaft hole of the present invention includes a base 3, a pillar 4 fixedly installed on one end of the base 3, and one end fixedly installed on the pillar 4 for the iron frozen motor. The steel reference body 5 fitted with the shell stator gear 1. The other end of the steel reference body 5 is coaxially provided with a steel reference shaft 6 for fitting the iron frozen motor casing bushing 2 . The outer diameter of the steel reference body 5 is 5-10um smaller than the lower deviation of the inner diameter of the stator gear 1 of the iron-frozen motor casing, and the outer diameter of the steel reference shaft 6 is 5-10um smaller than the lower deviation of the inner diameter of the iron-frozen motor casing shaft sleeve 2 10um. The ste...

A detector for qualification of the concentricity of an iron motor casing stator wall relative to a shaft hole comprises a base (3), a supporting column (4) and a steel base body (5). The supporting column is fixedly arranged at one end of the base (3), one end of the steel base body is fixedly arranged on the supporting column (4), the iron motor casing stator wall is in sleeve fit with the steel base body, a steel base shaft (6) is coaxially arranged at the other end of the steel base body (5), an iron motor casing shaft sleeve (2) is in sleeve fit the with the steel base shaft, the outer diameter of the steel base body (5) is 5-10mum smaller than the lower deviation of the inner diameter of the iron motor casing stator wall (1), and the outer diameter of the steel base shaft (6) is 5-10mum smaller than the lower deviation of the inner diameter of the iron motor casing shaft sleeve (2). The detector is high in detection speed, high in efficiency and good in effect.
Description
technical field [0001] The invention relates to the technical field of iron-frozen casing detection, in particular to a qualified detector for the concentricity of the stator gear relative to the shaft hole of the iron-frozen motor casing. Background technique [0002] figure 1 It is an iron frozen motor casing (commonly known in the industry, it is actually a kind of motor casing, and the motor casing is made of iron). The inner peripheral wall of the casing is commonly known as the stator gear 1 in the industry. A shaft sleeve 2 with a shaft hole 2.1 is provided. In order to check whether the concentricity of the stator gear to the reference shaft hole is qualified, at present, the most common method is to use a dial indicator to measure the stator gear for one circle, and calculate and analyze the obtained data. Within the range, it is a qualified product. If it exceeds the error range, it is a non-conforming product and needs to return to the previous process for rewor...
