Abstract
The invention relates to a motor strip line bar intrastrand line changing pattern weaving defect part repairing method. The invention is characterized in that the method comprises: a filler is made into paste, a strip line bar is horizontally placed on a platform surface and clamp plates are respectively clamped by virtue of flanges, the strip line bar defect part is filled with the filler, and a bamboo chip is utilized to strickle the filler; the strip line bar filling part is wound and strengthened by a polytetrafluoroethylene belt; and curing is carried out, and then a file and sand paper are utilized to polish the filling part. The invention has the advantages that measurement of the repaired motor strip line bar intrastrand line changing pattern weaving defect part is almost the same with other parts, the repaired part has no geometrical deformation and is pressureproof, the strip line bar is ensured to be smooth an have no gap, appearance is beautiful, insulation filling of the pattern weaving defect part is full and no intrastrand short circuit phenomenon is caused, and the electrical property is stable. The method provided by invention is simple in repairing operation and can be used for greatly improving the production efficiency.
Description
Technical field
The invention belongs to technical field of motors, particularly relate to thread-changing volume flower defect method for trimming between a kind of electric machine bar line stick thigh.
Background technology
At present, the stator bar line stick of large high-voltage motor is made up of several electromagnetic wires, needs compiling flower infall pad flexible micanite, and many glue of line part pad micarex is hot-forming, then carries out testing between thigh.Short circuit phenomenon between thigh appears in regular meeting in the time of in the process of the test, therefore must the short circuit electromagnetic wire be changed.Compile additional flexible micanite of flower crossover sites and the additional many glue micarex of straight line after the thread-changing of stator bar line stick and be destroyed, cause and compile the out-of-flatness of flower crossover sites, bar line stick quality and physical dimension are had a direct impact.In order to remedy above-mentioned defective; Need to adopt many glue micarex to fill; The bar line stick of filling is again through the mould heat pressure of bull forming press, and its manufacturing procedure is loaded down with trivial details, is difficult to mend flat rejected region because the bar line stick after filling is wrapped up main insulation (mica tape) through machine; Promptly do not reach supplementary result, influenced the quality and the physical dimension of bar line stick again.
Summary of the invention
The present invention provides thread-changing volume flower defect method for trimming between a kind of electric machine bar line stick thigh for solving the technical problem that exists in the known technology.
The purpose of this invention is to provide thread-changing between a kind of electric machine bar line stick thigh that improves bar line stick physical dimension and fabricating quality and compile the method for trimming of flower defect.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: flower defect method for trimming is compiled in thread-changing between the electric machine bar line stick thigh, it is characterized in that: comprise following operation:
1), modulation filler: allocate evenly in the ratio of 2:3:1 with mica powder, epoxy resin and curing agent, process paste;
2), with on the bar line stick placing flat work top; Through blocking orchid clamping plate are clamped in both sides, bar line stick straight line plane respectively; Flower defect filling paste filler is compiled in thread-changing between the bar line stick thigh, makes filler be higher than bar line stick plane on every side, with bamboo chip filler is wipeed off again;
3), reinforcing is twined at the filling position of bar line stick with teflin tape;
4), cured: the bar line stick that will twine after reinforcing was placed spontaneous curing at normal temperatures 24 hours, perhaps put into 120 ℃ drying baker oven dry and took out in 3.5-5 hour, placed cooling at room temperature then;
5), with after the bar line stick cooling, with making smooth with a file and sand paper will be filled position sanding of flat cunning and made it reach the design size requirement.
Advantage and good effect that the present invention has are: because the present invention adopts technique scheme; Make between the electric machine bar line stick thigh after the finishing thread-changing compile flower defect and excellent other spot size basically identical of line; Revising the position geometry does not have distortion and withstand voltage, has guaranteed the smooth no gap of bar line stick, appearance looks elegant; Compile flower defect insulation filling and enrich short circuit phenomenon between the nothing thigh, electric performance stablity.Finishing operation of the present invention is simple, production efficiency can be provided significantly.
