Abstract
The utility model discloses a novel stator core welding fixture which comprises a core tire and two support shafts. Two axial key grooves are arranged on the core tire, screw holes are arranged on end faces at two ends of the core tire, each support shaft comprises a fixing disc, butt joint threaded through holes are arranged on an end face at one end of each fixing disc, a fixing shaft is vertically arranged at the center of one end face of each fixing disc, and the fixing discs of the two support shafts are connected on the end faces at two ends of the core tire. The novel stator core welding fixture overcomes the defects of proneness to deformation of a pressing ring, poor welding efficiency, high operation difficulty and the like during welding of existing stator cores, and is convenient to rotate, simple to operate and capable of reducing welding deformation and improving welding efficiency.
Description
Technical field
The utility model belongs to the welding tooling field, is specifically related to a kind of novel stator core welding tooling.
Background technology
Stator core is the vitals that forms motor flux circuit and fixed stator coils, and it is compressed and formed an integral body by punching and various securing member.At present, adopt the mode of full weld, full weldering while on stator core, welding stator pressing ring, when welding, stator pressing ring due to the inequality of being heated can cause the distortion, thereby can't guarantee trim ring and stator core firm welding, affect the fastness that press-fits of stator core, in addition, if stator core is square, when welding, square stator core rotation difficulty is large, after welding an end, need upset that other end end face is exposed, be convenient to welding, square stator core rotates difficulty and strengthens, and welding efficiency is low.
The utility model content
The technical problems to be solved in the utility model is the defect such as easily make the trim ring distortion during for the welding of existing stator core, welding efficiency is poor, operation easier is large, provide a kind of and conveniently rotate, simple to operate, can reduce welding deformation, improve a kind of novel stator core welding tooling of welding efficiency.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of novel stator core welding tooling, comprise core tire and two back shafts, the core tire is provided with two axial keyways, and on the circumferential position of described two keyways in the core tire and Yan Xintai center is symmetric, and on the end face at core tire two ends, is provided with screw; Back shaft comprises a fixed disk, is provided with the docking tapped through hole corresponding with described screwhole position on fixed disk, and the fixed disk of two back shafts is connected on the two ends end face of core tire with the bolt respectively that docks of screw by described through hole; Described back shaft also comprises the fixed axis of being located on fixed disk.
Adopt a kind of novel stator core welding tooling of technical solutions of the utility model, two keyways are combined for corresponding stator grooved on stator core, by core tire and stator core fixation, thereby reduce the distortion of both ends of the surface when the welding trim ring, in addition, the end face at core tire two ends is provided with screw, back shaft comprises a fixed disk, be provided with the docking tapped through hole corresponding with described screwhole position on fixed disk, the fixed disk of two back shafts is connected to the two ends end face of core tire, by the screw at core tire two ends with together with through hole on two fixed disks is bolted, two fixed disks are connected with core tire both ends of the surface, make two fixed axis perpendicular to the stator core two ends, facilitate the rotation of stator core, thereby facilitate the trim ring welding of two ends end face, improve welding efficiency, simple to operate.
Further, the screw on described core tire end face is concentric distribution, and the docking tapped through hole on back shaft also is concentric distribution, and both concentric distances equate.Distributing with one heart is circle distribution, with one heart apart from being equivalent to circle diameter.Be more suitable for like this position docking.
Adopt a kind of novel stator core welding tooling of technical solutions of the utility model, when operation, two stator grooveds by core tire keyway on stator core are combined, make core tire and stator core fixation, then the fixed disk of two back shafts is coupled together screw and through hole by bolt, thereby two back shafts are fixed on to the two ends of core tire, make two back shafts be fixed on the stator core two ends, having formed the stator core two ends is two fixed axis, when the welding trim ring, the fixation of keyway and stator punching has reduced the distortion of trim ring when welding, two back shafts make the rotation of stator core convenient, after realizing that an end has welded, only need to press the back shaft of an end, the end face that can realize the other end exposes, facilitate the welding of the other end end face of stator core, easy to operate, can reduce the welding deformation rate, improve welding efficiency.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Fig. 1 is the schematic diagram of the utility model embodiment.
Fig. 2 is the end view of the utility model SMIS tire.
Fig. 3 is the sectional schematic diagram of back shaft in the utility model.
Fig. 4 is that schematic diagram is looked on the right side of Fig. 3.
The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, a kind of novel stator core welding tooling of the utility model, comprise core tire and two back shafts, wherein, be provided with two keyways 1 on the axial location of core tire, and two keyways 1 are located in the horizontal peripheral cross-section diameter of a circle of core tire two ends, the end face at core tire two ends is provided with four screws 2, back shaft comprises a fixed disk 4, be provided with four via hole 5(on fixed disk 4 and dock tapped through hole), be vertically installed with a fixed axis 3 on the center of 4 one end faces of fixed disk, the fixed disk 4 of two back shafts is connected to the two ends end face of core tire, described four screws 2 and four via holes 5 evenly are arranged on the annulus of same radius.
For a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement, these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
