Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of iron core rotation testing platforms, and specifically to an iron core rotation testing platform. Background Technology
[0002] Due to limitations in processing technology, materials, and personnel capabilities, iron cores sometimes deform after stacking and machining, including elliptical outer circles, bent busbars, and deformed ventilation ducts. Therefore, it is necessary to inspect the roundness, straightness, end face runout, and height of the ventilation ducts of the iron core during production.
[0003] Currently, in the absence of automatic coordinate measuring machine (CMM) equipment, existing methods often rely on squares and feeler gauges to measure the straightness of the generatrix, outside micrometers to measure the roundness of the outer circle, and vernier calipers to measure the height of the ventilation duct. Due to the limitations of the sampling points, existing measurement methods sometimes miss key change points, resulting in missed detections and distorted test results. In addition, the continuous sampling of points leads to a large workload and low testing efficiency.
[0004] Based on this, this utility model designs a core rotation detection platform to solve the problems of missed sampling points, distorted results, and low efficiency in the existing technology. Utility Model Content

[0007] As a preferred embodiment of this utility model, two rod positioning seats are symmetrically fixedly installed at the upper and lower ends of the back of the column, and a guide rail rod is fixedly connected between the two rod positioning seats at different ends. A guide bracket is movably installed between the two guide rail rods, and a counterweight is provided on the guide bracket. A second lifting ring is provided at the center of the upper end of the guide bracket.
[0008] As a preferred embodiment of this utility model, a first roller is provided between the two guide rails on the front side of the guide rail mounting plate, and a second roller is provided between the two guide rail rods on the back side of the column.
[0009] As a preferred embodiment of this utility model, the first roller on the guide rail mounting plate and the second roller on the back of the column are set at the same height and on the same horizontal line.
[0010] As a preferred embodiment of this utility model, a soft steel wire rope is fixedly connected to the second lifting ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. When using this utility model, to measure the outer diameter of the stator core, only one point of the outer diameter needs to be measured with an outside micrometer. Then, the reducer is started, and the turntable is rotated through the meshing of the reducer gear and the gear ring. The runout of the outer diameter of the core relative to this point is measured with a dial indicator. The same method is used to measure the runout of the end face of the core. When measuring the height of each step of the stepped core, one point can be taken, the height can be measured with a vernier caliper, and then the reducer is started to drive the turntable to rotate. The runout of the end face of that step relative to this point is measured with a dial indicator. This measurement method takes continuous points without omission, and the results are true and reliable. The measurement is more convenient and efficient.
[0015] 2. In use, the vertical height of the column relative to the base can be adjusted by the column adjustment pad. The guide rail on the guide rail mounting plate allows the dial indicator base connecting plate to move up and down, facilitating the measurement of the straightness of the iron core busbar and the height change of each step. The guide rail clamp is used to ensure the stability and measurement accuracy of the dial indicator. The design of the counterweight on the back ensures the stability of the dial indicator base and the dial indicator. The detection cantilever installed at the top of the column can be used to clamp the dial indicator to measure the runout of the iron core end face, which is convenient, efficient and ensures the accuracy of the measurement.
