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
The present invention relates to the technical field of direct current generator maintenance, be specifically related to a kind of cleaning tool of mica slot maintaining.
Background technology
Direct current generator is in operation because carbon brush and commutator sliding friction can be gathered carbon dust and conduction dust in the mica ditch, very easily causes short circuit between the commutator segment sheet behind the long-play; Simultaneously; Because the hardness of commutator-segment insulation micarex is greater than the switching-over copper sheet; The coefficient of expansion of switching-over copper sheet is again greater than micarex, so the micarex of the commutator after the wearing and tearing can protrude the copper sheet surface, causes spark to produce; The commutator of burning, can cause ring fire to burn out motor when serious influences company's ordinary production.
Subsidiary factory is to a word screwdriver of common small sized before the cleaning of direct current generator mica slot, but removes poor effect and can't carve down the micarex of protrusion, often cause the motor sparking serious, brought potential safety hazard for the normal operation of direct current generator.Subsidiary factory just with the outer repairing of direct current generator committee, has increased direct current generator maintaining cost afterwards.
Summary of the invention
In view of the defective that above-mentioned prior art exists, the objective of the invention is to propose a kind of simple in structure, easy to use, can be with the micarex of protrusion and the instrument that the carbon dust in the mica slot, conduction dust are removed.
The object of the invention will be achieved through following technical scheme: a kind of direct current generator mica slot cleaning tool is characterized in that: comprise two clamping elements, a saw blade, said saw blade are sandwiched between said two clamping element lower edges, and the two laminates and is fixed as one.
The technical scheme that the present invention further limits is: said two clamping elements are fixed for the AB glue glued adhesion.
Further, aforesaid direct current generator mica slot cleaning tool, said clamping element is plank or rubber and plastic boards.
Further, aforesaid direct current generator mica slot cleaning tool, said saw blade sawtooth angle is consistent with mica slot kerve direction.
Further, aforesaid direct current generator mica slot cleaning tool, said saw blade sawtooth length is 1.5mm～3mm.
The present invention, its outstanding effect is: after using the present invention, to the carbon dust in the direct current generator mica slot, when the conduction dust is cleared up, can ensure effectively that direct current generator safety normally moves, also save external coordination maintaining expense for company simultaneously.The design's effect is remarkable, practical, has improved operating efficiency, and simple in structure, and is easy and simple to handle, and production cost is low.
Following constipation closes the embodiment accompanying drawing, and specific embodiments of the invention is done further to detail, so that technical scheme of the present invention is easier to understand, grasp.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a left view of the present invention.
The specific embodiment
A kind of direct current generator mica slot cleaning tool that present embodiment provides is used to clear up carbon dust, conduction dust in the direct current generator mica slot, and structure is as shown in the figure, comprises clamping element 1, clamping element 2, and this clamping element preferably adopts rubber and plastic boards in the present embodiment.Wherein accompany saw blade 3 between the lower edge of clamping element 1,2, the two laminates through the AB glue glued adhesion and is fixed as one.Simultaneously, the sawtooth length of this saw blade preferably adopts 1.5mm～2mm.And the upper limb of clamping element 1,2 adopts arc-shaped structure, is convenient to grasping.
When said apparatus uses; Clamp the cleaning tool both sides with forefinger and middle finger, forefinger and palm are pushed down rubber and plastic boards both sides circular arc respectively, carry out kerve along oblique 45 degree on the mica slot earlier; Carry out kerve along mica slot declivity 45 degree again, keep the sawtooth angle consistent simultaneously with mica slot kerve direction.
The present invention uses the back effect obvious, to the carbon dust in the direct current generator mica slot, conduction dust when clearing up, can ensure effectively that direct current generator safety normally moves, and has also saved external coordination maintaining expense for company simultaneously.The design's effect is remarkable, practical, has improved operating efficiency, and simple in structure, and is easy and simple to handle, and production cost is low.
Except that the foregoing description, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
