Abstract
The utility model relates to the field of the manufacturing of motors and especially relates to a positioning device for the spot welding of a stator end plate. The positioning device for the spot welding of the stator end plate is applicable to the positioning device for the spot welding of the stator end plate of a large-sized high-voltage traction motor. The positioning device for the spot welding of the stator end plate comprises a positioning disk and a positioning seat which are coaxially and rotatably connected together, wherein a positioning key, a groove-shaped rod, an identical-graduation positioning pin and a positioning sleeve are arranged on the positioning disk. The positioning device can complete positioning in the spot welding of a plurality of stator punched sheets, so that the internal circle, the external circle and the groove shape of the punched sheets can be regular and uniform after overlapping spot welding, the internal circle, the end plate and the punched sheets are consistent in the external circle and the groove shape after stator cores are overlaid and pressed, the reliability in the production and operation of the punched sheets of the motor is guaranteed, the rejection rate caused by the manual trimming spot welding is avoided, and the working efficiency is greatly increased.
Description
Technical field
The utility model relates to field of motor manufacturing, and especially stator end plate spot welding positioner is applicable to large-scale high pressure, the used positioner of traction electric machine stator end plate spot welding.
Background technology
At present, in high pressure, traction electric machine manufacturing, it is one that stator end plate has many overlapping spot welding of stator punching of employing.Generally spot welding on YR type single phase ac resistance welding machine, this welding equipment does not have corresponding positioner, and the general arrangement lamination by hand that adopts is folded the punching of some, and inside and outside circle, flute profile basically identical send sheet spot welding by hand.The stator end plate of some postwelding need guarantee that inside and outside circle, flute profile are consistent with stator punching, just can make stator core laminate end plate and punching inside and outside circle, flute profile is consistent, guarantees stator core product quality and motor performance.
This manual arrangement lamination mode, the stator terminal inside and outside circle, the flute profile that are difficult to the guarantee point postwelding are consistent with stator punching.And the spot size position dimension is uncontrollable, and solder joint equal indicative error is bigger, and the punching scrappage is high.This mode obviously can not satisfy the product quality requirement, and stator terminal inside and outside circle, flute profile are consistent with stator punching, spot size position dimension, solder joint equal indicative can not be controlled, and have a strong impact on product quality.Need every end plate adjustment to proofread and correct spot size position dimension and equal indicative simultaneously, production efficiency reduces.This manual arrangement lamination mode is not suitable for high pressure, traction electric machine stator end plate spot welding manufacturing technique requirent.
The utility model content
The deficiency that the utility model purpose is intended to overcome above-mentioned prior art provides a kind of positioner, and the punching installing and locating is exchanged convenient, does not need every end plate adjustment to proofread and correct the stator end plate spot welding device of spot size position dimension and equal indicative.
A kind of stator end plate spot welding positioner comprises coaxial positioning disk and the positioning seat that is rotatably connected together, and said positioning disk is provided with positioning key, flute profile rod, equal indicative alignment pin and positioning sleeve.
Said positioning seat is provided with the cannelure of placing said steel ball.
Be provided with steel ball and bearing between said positioning disk and the positioning seat.
The utility model adopts technique scheme, compared with prior art can realize following beneficial effect:
Said device will be accomplished many stator punching spot welding location, make overlapping some postwelding inside and outside circle of many punchings, flute profile neat and consistent, make stator core laminate end plate and punching inside and outside circle, flute profile is consistent, has guaranteed motor stamping production and reliability of operation.Scrappage when avoiding arrangement spot welding by hand produces the raw-material waste of punching and the waste in man-hour.In motor stator end plate pinpoint welding procedure, improve product quality and production efficiency greatly.
Said device is through equal indicative location and pin-and-hole location, and the positioning key location, and solder joint is even when guaranteeing rotation spot welding.The solder joint equal indicative is effectively controlled, and improves the quality of products greatly.Said device guarantees end plate spot size position dimension relative fixed, and producing in batches does not need every end plate to proofread and correct the spot size position dimension, increases work efficiency greatly.
Description of drawings
Fig. 1 is the horizontal direction cutaway view of a kind of stator end plate spot welding of the utility model with positioner;
Fig. 2 is that the positioner vertical view is used in a kind of stator end plate spot welding of utility model;
Wherein 1, positioning disk; 2, positioning key; 3, positioning seat; 4, flute profile rod; 5, equal indicative alignment pin; 6, positioning sleeve; 7 steel balls; 8 bearings.
The specific embodiment:
Accompanying drawing discloses the structural representation of the related stator end plate spot welding of the utility model with a preferred embodiment of positioner without limitation, below will combine accompanying drawing that the technical scheme of the utility model at length is described.
The described stator end plate spot welding of the utility model positioner comprises positioning disk 1, positioning key 2, following positioning seat 3, flute profile rod 4, equal indicative alignment pin 5, positioning sleeve 6, steel ball 7 and bearing 8.
Said device cooperates the location through positioning disk 1 with the punching internal diameter, makes external diameter unanimity in the punching; Cooperate the location through three groups of flute profiles rod 4 with the punching flute profile simultaneously, make flute profile neat and consistent after many overlapping spot welding of punching.Make stator core laminate end plate and punching inside and outside circle, flute profile is consistent.
Halving hole under utilizing on the positioning seat and the equal indicative alignment pin 5 on the positioning disk 1 and positioning sleeve 6 location guarantee the requirement of solder joint equal indicative.Positioning key 2 on the positioning disk 1 makes punching and positioning disk circumferential position relative fixed, and solder joint is even when guaranteeing rotation spot welding.The solder joint equal indicative is effectively controlled.
During spot welding frock and welding machine rifle head position are adjusted fixingly, guarantee end plate spot size position dimension relative fixed, producing in batches does not need every end plate to proofread and correct the spot size position dimension, increases work efficiency greatly.
Utilize steel ball 7 that positioning disk 1 and die shoe are rotated with roll mode, flexible and convenient operation during rotation spot welding.Effectively increase work efficiency.
