Problems solved by technology

[0003] Before cleaning the mica groove of the DC motor, the branch factory often used a small screwdriver, but the cleaning effect was not good and the protruding mica plate could not be engraved, which often caused serious ignition of the motor, which brought safety to the normal operation of the DC motor. Hidden danger
Afterwards, the branch factory outsourced the repair of the DC motor, which increased the maintenance cost of the DC motor.

Embodiment Construction

[0014] A DC motor mica tank cleaning tool provided in this embodiment is used to clean carbon powder and conductive dust in the DC motor mica tank. The structure is shown in the figure, including a clamping part 1 and a clamping part 2. In this embodiment The clamping part preferably adopts a rubber-plastic plate. The saw blade 3 is clamped between the lower edges of the clamping parts 1 and 2, and the two are fixed as one by AB glue. At the same time, the tooth length of the saw blade is preferably 1.5mm-2mm. In addition, the upper edges of the clamping parts 1 and 2 adopt a circular arc structure, which is convenient for grasping.

[0015] When the above device is in use, use the index finger and middle finger to clamp the two sides of the cleaning tool, press the index finger and the palm respectively to press the arcs on both sides of the rubber and plastic plate, first pull the groove along the mica groove up 45 degrees, and then along the mica groove 45 degrees down Pe...

Abstract

The invention discloses a cleaning tool for a mica groove of a direct current motor. The cleaning tool is characterized by comprising two clamping elements and a saw blade, wherein the saw blade is clamped between the lower edges of the two clamping elements, and the saw blade and the two clamping elements are integrally superposed and fixed. After the cleaning tool provided by the invention is used, the safe and normal running of the direct current motor is effectively ensured during the process of cleaning carbon dust and conductive dust in the mica groove of the direct current motor; the outsourcing maintenance cost is saved for companies; the design effect is obvious and the practicability is strong; the operation efficiency is increased; the structure is simple; the operation is convenient; and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of DC motor maintenance, in particular to a cleaning tool for mica groove maintenance. Background technique [0002] During the operation of the DC motor, due to the sliding friction between the carbon brush and the commutator, carbon powder and conductive dust will accumulate in the mica groove, which will easily cause a short circuit between the commutator plates after long-term operation; The hardness of the commutator is greater than that of the commutator, and the expansion coefficient of the commutator is greater than that of the mica plate, so the mica plate of the worn commutator will protrude from the surface of the copper plate, resulting in sparks, burning the commutator, and in severe cases. The ring fire burned out the motor and affected the company's normal production. [0003] Before cleaning the mica groove of the DC motor, the branch factory often used a small screwdriver, but the cleaning ...
