Description
Technical field
The utility model relates to electric machine iron core processing unit (plant), particularly a kind of Novel stator iron core laminated fixture avoiding teeth portion to flick.
Background technology
Stacked by the stator punching of some in the middle part of the stator core of motor, two ends add tooth support (tooth support becomes a sheet shape torus by four toothed fanning strip assembly weldings) successively, trim ring compresses, wherein again through welding column, its two ends and trim ring weld composition one part.During assembly welding, part must weld under maintenance impaction state.The maintenance of impaction state then needs to be realized by press mounting die.Compressing concrete mode is: respectively have one piece of clamping cap up and down at workpiece, first pressure cylinder compression mould pressing plate is passed through by forcing press, transmission of pressure is applied on trim ring and tooth support and compresses again, again by four cover screw rod, nuts, workpiece to be tightened together with clamping cap maintenance impaction state, after getting forcing press external welding, turn on nut, shed clamping cap.
But existing compressing method exists cannot ensure the problem that the tooth of tooth support and stator punching is close together.At this moment because the tooth of tooth support is that punching forms, tooth local burr varies in size.Require smooth after four fanning strip assembly weldings, and clamping cap is exerted pressure, plane also requires smooth.Tooth support is plane under clamping cap effect, but after shedding clamping cap, then due to the problem of its local burr or welding procedure, produce and tilt distortion, produce be separated with the tooth of stator punching.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of Novel stator iron core laminated fixture avoiding teeth portion to flick is provided, it is after shedding clamping cap, and tooth support keeps the thrust to stator punching direction, realizes the object avoiding teeth portion to flick.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of Novel stator iron core laminated fixture avoiding teeth portion to flick, by mold base, mould lower platen, mould top board, lower clamping ring, lower tooth support, upper trim ring, upper tooth support, screw nut assembly is formed, the upper surface that stator core laminates punching adds successively loads onto tooth support, upper trim ring and mold pressing plate, lower tooth support is installed additional at the lower surface of stator core, lower clamping ring and bed die pressing plate, fixed by bolt and nut component between mould top board and mould lower platen, it is characterized in that: described upper tooth support and the periphery of lower tooth support be all shaped with dish pressure edge, this dish pressure is along the teeth portion towards stator core.
And, be shaped with at the lower surface of mould top board and the upper surface of mould lower platen and press the groove corresponding along position with described dish.
Advantage of the present utility model and beneficial effect are:
1, Novel stator iron core laminated fixture of the present utility model, change the shape of tooth support and lower tooth support, changed into the disk like with dish pressure edge by plain film shape, after clamping cap compresses, tooth support can remain the pressuring action of periphery to iron core teeth portion, prevents flicking of tooth support and stator core teeth portion.
2, Novel stator iron core laminated fixture of the present utility model, improves clamping cap structure, is shaped with the groove corresponding along position with the dish pressure of tooth support at its seal face, when avoiding compressing, disk like tooth support is flattened, and guarantees that tooth support remains without flicking.
3, the utility model scientific structure design is reasonable, and it is after shedding clamping cap, and tooth support still can keep the thrust to stator punching direction, realizes the object avoiding teeth portion to flick, products quality guarantee.

Embodiment
Below by specific embodiment, the utility model is described in further detail, and following examples are just demonstrated descriptive explanation, are not determinate words, can not limit protection range of the present utility model with this.
A kind of Novel stator iron core laminated fixture avoiding teeth portion to flick, by mold base 9, mould lower platen 8, mould top board 2, lower clamping ring 6, lower tooth support 7, upper trim ring 3, upper tooth support 4, screw nut assembly 10 is formed, overlapping punching sheet 5 upper surface of stator core adds successively loads onto tooth support, upper trim ring and mold pressing plate, lower tooth support is installed additional at the lower surface of stator core, lower clamping ring and bed die pressing plate, fixed by bolt and nut component between mould top board and mould lower platen, it is characterized in that: described upper tooth support and the periphery of lower tooth support be all shaped with dish pressure along 12, this dish pressure is along the teeth portion towards stator core.
Be shaped with at the lower surface of mould top board and the upper surface of mould lower platen and press the groove 11 corresponding along position with described dish.
Forcing press is by pressure cylinder 1 compression mould top board, then transmission of pressure is applied to trim ring and upper tooth support compresses.Upper tooth support and lower tooth support change the disk like with dish pressure edge into by plain film shape, after clamping cap compresses, tooth support can remain the pressuring action of periphery to iron core teeth portion, prevent flicking of tooth support and stator core teeth portion.Being shaped with the groove corresponding along position with the dish pressure of tooth support at the seal face of clamping cap, when avoiding compressing, disk like tooth support being flattened, guaranteeing that tooth support remains without flicking.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
