Problems solved by technology

The gauge of many motor compensation straight lines is small and the main pole is firmly bonded to the main pole iron core after the main pole is dipped in paint. , the tensile strength is poor, and the entire main pole is often scrapped because the compensation line breaks and cannot be taken out during extraction. The loss is huge, and the repair time of the motor will be very long

Embodiment Construction

[0016] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0017] combine figure 1 schematic diagram and figure 2 First, in step S101, install the main pole where the pressure breaking compensation line 2 is located on the machine base 5, and weld a copper lifting lug 1 to the end of the breaking pressure compensation line 2, and the welding must be firm. Then, in step S102, the slot wedge 3 on the compensation straight line 2 is heated until the slot wedge 3 is loosened, and the slot wedge 3 is removed while it is hot. Next, in step S103, two welding torches are used to heat the compensation line 2. When heating, pay attention to moving up and down evenly so that the insulation of the compensation line 2 is heated evenly until the insulation is carbonized. The compensation line 2 is hoisted by driving, and the jog button must be used to operate the driving to avoid lifting. If the speed is too fas...

Abstract

The invention provides a crushing repair method for a compensation straight line of a main pole of a DC motor, which comprises the following steps: firstly, welding compensation straight line drawing lifting lugs; then carrying out flame heating to take a main pole slot wedge; carrying out flame heating and traveling drawing to take the compensation straight line; carrying out shaping and slot cleaning on a main pole punching sheet; and finally, installing the newly manufactured straight line. The application of the crushing repair method can avoid scrapping of an iron core of the main pole, greatly reduce the crushing repair cost and shorten the repair time. According to the invention, a compensation straight line insulation carbonization technology, a compensation straight line integrated taking technology and the like are adopted to greatly improve the crushing repair speed and reduce the crushing repair cost.

Description

technical field [0001] The present invention relates to a motor, especially a motor whose main pole uses a compensating linear structure. Background technique [0002] With the rapid development of construction, metallurgy, and chemical industries, motors are used more and more widely, and the main pole compensation linear breakage accident is prone to occur during the manufacturing or later use of the motor, which must be repaired before use. For many motors, the gauge of the compensation line is small, and the compensation line and the main pole iron core are firmly combined after the main pole is dipped in paint. Once the compensation line is broken, the success rate of the conventional oven heating extraction method is extremely low, mainly because the material of the compensation line is copper. , The tensile strength is poor, and the entire main pole is often scrapped because the compensation straight line fracture cannot be taken out during extraction, resulting in hu...
