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 a kind of motor strip line bar intrastrand line changing pattern weaving defect part repairing.
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 the short circuit electromagnetic wire must be changed.It is destroyed to compile the additional many glue micarex of additional flexible micanite of flower crossover sites and straight line after the thread-changing of stator bar line stick, causes and compiles 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, its manufacturing procedure is loaded down with trivial details, because the bar line stick after filling is wrapped up main insulation (mica tape) through machine and is difficult to mend flat rejected region, 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 a kind of motor strip line bar intrastrand line changing pattern weaving defect part repairing for solving the technical problem that exists in the known technology.
The purpose of this invention is to provide and a kind ofly improve the bar line stick physical dimension and make the method for trimming that the flower defect is compiled in thread-changing between the electric machine bar line stick thigh of quality.
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, make paste;
2), with on the bar line stick placing flat work top, by 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), with teflin tape reinforcing is twined at the filling position of bar line stick;
4), solidify and process: the bar line stick that will twine after reinforcing was placed at normal temperatures spontaneous curing 24 hours, perhaps put into 120 ℃ drying baker oven dry and took out in 3.5-5 hour, placed then at room temperature cooling;
5), with after the bar line stick cooling, will fill the position with file and sand paper and be polished flat cunning and make it reach the design size requirement.
Advantage and good effect that the present invention has are: because the present invention adopts technique scheme, it is basically identical with excellent other spot size of line to make between the electric machine bar line stick thigh after the finishing thread-changing compile the flower defect, revise the position geometry and do not have distortion and withstand voltage, guaranteed the smooth gapless 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.
