Abstract
The present invention relates to a kind of holistic position bar welding method.Be characterized in: at first positioning bar is located in motor stator support tooth support side, again along motor shaft on positioning bar top, tooth support opposite side location, then positioning bar and stator frame wall point postwelding are removed frock, with positioning bar and stator frame wall plug welding together, described along motor shaft to finishing according to following processing step on positioning bar top, tooth support opposite side location: when the processing out frame, at tooth pressure board slot opposite side, process all grooves, with the groove is benchmark, the angle steel point is welded on the middle support wall of the adjacent positioning bar of two-phase, direct code punching on angle steel is put benchmark as positioning bar top.The accurate positioning of positioning bar of the present invention, high efficiency, the operating safety factor height is saved the frock material.
Description
Technical field
The present invention relates to a kind of welding method, particularly the holistic position bar welding method of punching in the electricity generator stator stand.
Background technology
At present, the weldering of the pendulum of punching positioning bar needs a large amount of frock and manpower in the electricity generator stator stand.See also Fig. 2, general step is: 1, earlier tooth support is inserted in the support wall groove, the lower end is supported with its frock, and leveling; 2, the upward punching of certain altitude of sign indicating number in the above is as positioning bar bottom positioning reference; 3, positioning bar is put into the punching groove; 4, on punching, put the I-steel number layer of certain altitude along circumference, general unit approximately needs about 130, puts liner plate again on adjacent two I-steel, generally needs the 20-40 piece, after the leveling with the spot welding of support wall; 5, the punching of certain altitude on the sign indicating number on liner plate.As positioning bar top positioning reference; 6, positioning bar and stator frame wall point postwelding are removed frocks such as punching, liner plate, I-steel, together with positioning bar and stator frame wall plug welding.Above-mentioned welding method need be with a large amount of manual work, and inefficiency has potential safety hazard, and the location of positioning bar is inaccurate, and the frock material usage is many, and liner plate can not be general.
Summary of the invention
The present invention provides a kind of easy, easy row, saving of labor, material-saving, holistic position bar welding method that coefficient of safety is high for solving the technical problem that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of holistic position bar welding method, at first positioning bar is located in motor stator support tooth support side, again along motor shaft on positioning bar top, tooth support opposite side location, then positioning bar and stator frame wall point postwelding are removed frock, with positioning bar and stator frame wall plug welding together, described along motor shaft to finishing according to following processing step on positioning bar top, tooth support opposite side location: when the processing out frame, at tooth pressure board slot opposite side, process all grooves, with the groove is benchmark, the angle steel point is welded on the middle support wall of the adjacent positioning bar of two-phase, direct code punching on angle steel is put benchmark as positioning bar top.
Described groove is positioned at highly inwardly 120-150mm place of stator core, and the groove degree of depth is 0.5mm.
Described angle steel is a unequal angle.
The specification of described not angle steel is 5 * 80 * 130.
Advantage and good effect that the present invention has are: because the location on positioning bar top is to decide benchmark by machining, and the accurate positioning of positioning bar, high efficiency, the operating safety factor height is saved the frock material.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of background technology of the present invention.
Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, pendulum soldering method of the present invention, 1, when car out frame 6, at tooth support 5 groove opposite sides, the dark groove 8 of the processing 0.5mm of the inside 120-150mm of iron core height place; 2, put bottom tooth support 5 and punching 3 by former method, put into positioning bar 1; 3, with on the lathe the groove of being processed 8 be benchmark, unequal angle 7 is welded on the support wall in the middle of the adjacent positioning bar 1 of two-phase equably, direct code punching 3 on angle steel 7 is put benchmark as positioning bar 1 top; 4, positioning bar 1 and stator frame wall point postwelding are removed frock, together with positioning bar 1 and stator frame wall plug welding.
See also Fig. 2 compared with the prior art, bold improvement has been done in layer punching 3 of burn-oning to pendulum, has saved a large amount of I-steel 4 and liner plate 2, only can finish with 5 * 80 * 130 unequal angle, and unequal angle can be general.For actual production provides a kind of easy, easy row, saving of labor, material-saving, process that coefficient of safety is high.
Advantage of the present invention is: 1, saved a large amount of frock materials: former 130 200mmx160mm I-steel and liner plate replaced by 40 5x80x130 unequal angles. 2, highly versatile: former frock Used I-steel can be general, but liner plate can not, it is different and different with out frame iron core place diameter. And can be used for the support of any diameter with unequal angle. 3, high efficiency: former to put a unit big Need approximately 4-5 name workman, 2-3 days time. Only need 1-2 name workman after improving, just can finish with time half a day. 3, accuracy height: former two-layer I-steel adds liner plate, and the horizontal direction accumulated error is big, and the leveling difficulty is big, Therefore the positioning bar string of putting weldering is also big apart from error, easily brings hidden danger to chip. With on the lathe after the improvement The groove of processing is horizontal reference, and not needing the people is leveling, and no accumulated error is put rear positioning bar string apart from standard Really. 4, safety coefficient height. Thereby guaranteed carrying out smoothly of chip.
