[0004] The inner diameter lever dial indicator is used to measure the roundness of the motor stator, which has high requirements for operators, and ordinary operators are prone to inaccurate readings and large errors when measuring
At the same time, the single measurement of the existing inner diameter lever dial indicator takes a long time. When batch measurement is required, this measurement method is inefficient
For this reason, the inner diameter lever indicator is suitable for use in the laboratory, which is not suitable for use in mass measurement in the production workshop

Embodiment
[0023] Figure 1 ~ Figure 3 It is the outline structure diagram of the motor stator roundness measuring device in this embodiment, including a base plate 1, on which a measuring head mounting plate 7 is arranged to place a measuring head 6, the measuring head 6 is in a columnar structure, and its height meets The test requirements for the motor stator (the workpiece under test). The outer diameter of the measuring head 6 abuts against the inner diameter of the motor stator placed thereon, so that the motor stator will not shake when placed on the measuring head 6, but does not affect the manual rotation of the motor stator to make it rotate relative to the measuring head 6. The measuring head 6 is provided with a gap, and a measuring point in contact with the inner diameter of the motor stator is provided at the gap, and the inside of the measuring point is in contact with the measuring head of the displacement sensor, so that the displacement sensor can sense the motor on the...

The present invention discloses a motor stator roundness measuring device, and relates to the technical field of stator roundness detection. The device comprises a bottom plate; a measuring head mounting plate for placing a measuring head is arranged on the bottom plate; the measuring head is used to place a to-be-measured workpiece, and a measuring point in contact with the inner diameter of theto-be-measured workpiece is arranged on the measuring head; the inside of the measuring point is in contact with the measuring head on the displacement sensor, so that the displacement sensor can sense the rotation variable of the to-be-measured workpiece on the measuring head; an electric control box for processing the rotation variable is arranged outside the measuring head; and the obtained inner diameter value and measured value are displayed on the liquid crystal display. According to the device disclosed by the present invention, the roundness test is performed on the motor stator, and the on-site personnel only needs to adjust the rotation angle of the motor stator, so that the operation difficulty of the on-site personnel is greatly simplified, the speed of measuring the roundnessis fast, and a large quantity of measurement operations in the production workshop can be satisfied.
Description
technical field [0001] The invention relates to the technical field of stator roundness detection, and relates to a motor stator roundness measurement device, in particular to a motor stator applied to an air-conditioning compressor. Background technique [0002] The air conditioner compressor stator is spliced by multiple coil groups. There will be grooves between the coil groups. If the roundness of the stator is not up to standard, the rotor will be stuck. The true roundness (referred to as roundness) is expressed by the radial offset of the actual contour relative to the ideal circle, that is, the difference between the maximum radius and the minimum radius relative to the same circle center. [0003] At present, the inner diameter lever dial indicator (also known as the inner diameter dial indicator) is mainly used to measure the roundness of the stator, and the linear displacement of the measuring head (measuring head) is changed into the angular displacement of the ...
