Embodiment 1

[0022] A method for detecting the inner diameter size of a magnetic pole coil of a generator is that after the magnetic pole coil is subjected to flat winding of copper strips, coil annealing, cold pressing, lead wire bending, and inter-turn insulation for inter-turn hot pressing, the outer side of the magnetic pole coil is sanded. The inner diameter size of the magnetic pole coil is detected by using the detection and verification die to simulate the magnetic pole iron core, so that the verification die can pass through the magnetic pole coil smoothly, and the purpose of detecting the inner diameter of the magnetic pole coil is realized. When the inner diameter of the magnetic pole coil is detected by using the detection and verification die to simulate the magnetic pole core, consider the insulation between the pads and the turns of 1-3mm. In order to ensure the overall quality of the inner insulation and save the pole body insulation material.

Embodiment 2

[0026] A generator magnetic pole coil inner diameter size detection device, in order to detect a calibration mold, comprising 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 is provided with a fixed handle 2, which is fixed The handle 2 is fastened on the check plate 1 by the lock nut, the pressing plate 4 and the fastening bolt 5 . The verification board 1 is a 10mm thick glass cloth board with an arc structure on both sides. After the production of one magnetic pole coil is completed, the calibration board can be transformed into the magnetic pole coil of other products, thereby reducing the consumption of raw materials and improving the utilization rate of tooling.

Abstract

The invention relates to a method and a device for detecting the internal diameter size of a pole coil of a generator, belonging to the technical field of generators. The method for detecting the internal diameter size of a pole coil of a generator is characterized in that after the pole coil forms by carrying out copper bar edge-winding, anneal, cold press, lead wire bending, and insulation of cushion circles for heat pressing among circles, a detection and check die simulates a pole iron core to detect the internal diameter size of the pole coil, and the purpose of detecting the internal diameter size of the pole coil is realized after the die goes through the pole coil smoothly. The device for detecting the internal diameter size of a pole coil of a generator is characterized in that the detection and check die comprises a check board, a fixed handle, a lock net, a pressing plate and a binding bolt, wherein the fixed handle is arranged on the check board by the lock net, the pressing plate and the binding bolt. The invention has the advantages of simple structure, convenient use, low labor intensity and simple operation, saving materials, having quick speed when the pole iron core interlinks poles, ensuring internal insulation quality of the pole coil, and the like.

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 unit adopts an advanced design concept, and the dimensional control tolerance is very strict. And the end design mostly adopts 3R structure, in order to save the space of the unit, save the copper material, and reduce the production cost of the unit. However, the magnetic pole coil with this structure is prone to defying at the 2R angle when the magnetic pole iron core is set, and the inner diameter needs to be repaired, which affects the insulation quality of the coil pole body and the beautiful appearance. And the electrical performance is unstable. It is usually necessary to simulate the magnetic pole iron core and cast a wooden mold to detect the inner diameter of the magnetic pole ...
