Embodiment 1

[0022] A method for detecting the inner diameter of the magnetic pole coil of a generator is that the magnetic pole coil is subjected to flat winding of copper bars, coil annealing, cold pressing, lead wire simmering and bending, pad inter-turn insulation for inter-turn hot pressing, and then performs sanding treatment on the outside of the magnetic pole coil. The inner diameter size of the magnetic pole coil is detected by using the detection verification model to simulate the magnetic pole core, so that the verification model can pass through the magnetic pole coil smoothly, and the purpose of detecting the inner diameter size of the magnetic pole coil is realized. When using the detection calibration model to simulate the magnetic pole core to detect the inner diameter of the magnetic pole coil, consider padding the inter-turn insulation by 1-3mm. In order to ensure the overall quality of the inner insulation and save the insulation material of the body.

Embodiment 2

[0026] A generator magnetic pole coil inner diameter size detection device, in order to detect the calibration mold, including a calibration plate 1, a fixed handle 2, a lock nut 3, a pressure plate 4, and a fastening bolt 5, the calibration plate 1 has a fixed handle 2, fixed The handle 2 is fastened on the check plate 1 by the lock nut, the pressure plate 4 and the fastening bolt 5 . The verification board 1 is a 10mm thick glass cloth board with curved structures on both sides. After the production of a magnetic pole coil is completed, the verification board can be used for remanufacturing the magnetic pole coils of other products, which reduces the consumption of raw materials and improves the utilization rate of tooling.

Description

technical field [0001] The invention belongs to the technical field of generators, and in particular relates to a method and a device for detecting the inner diameter size of a magnetic pole coil of a generator. Background technique [0002] At present, the magnetic pole coil of the tubular flow unit adopts advanced design concepts, and the dimensional control tolerance is very strict. And the terminal design mostly adopts 3R structure, in order to save the use space of the unit, save copper materials and materials, and reduce the production cost of the unit. However, the magnetic pole coil with this structure is prone to violation at the 2R angle when the magnetic pole core is placed, and the inner diameter needs to be ground, which affects the insulation quality and appearance of the coil pole body. And the electrical performance is unstable. Usually it is necessary to simulate the pole iron core casting wooden mold as the detection of the inner diameter of the pole coil...
