Abstract
The utility model discloses an adjustable tight mould that rises, including child core, width of cloth muscle, top board and holding down plate, the child core be the columniform cylinder, its both ends are equipped with the axle that stretches out the terminal surface respectively, the axle at child core both ends has top board and a holding down plate through bearing swing joint respectively, width of cloth muscle cladding at the outer periphery of child core, width of cloth muscle set up for the components of a whole that can function independently, top board and holding down plate are respectively through a spring catch and a width of cloth muscle fixed connection, top board and holding down plate punish with the clearance between the muscle and has do not cup jointed the child cover, the child is overlapped and is the circle of ring type, the child overlap respectively with top board and holding down plate fixed connection. Compared with the prior art, the beneficial effects of the utility model are that: avoided guaranteeing the quality of the interior circle of stator core because the stator core internal diameter that interference fit leads to produces the burr scheduling problem, reduce the manufacturing and the use of pressure equipment mould, when also having made things convenient for the pressure equipment operation, still reduced the use of pressure equipment mould.
Description
Technical field
The utility model belongs to field of motor manufacturing, be applicable to motor manufacturing produce in press-fit operation, relate to a kind of adjustable tensioner mold.
Background technology
In the manufacture production of motor, press-fit and belong to a wherein important ring.In former stator press-loading, tire core is forced through iron core inner circle with the smooth object that comes to perfection by interference expander under the effect of forcing press.Expander is forced through stator core inner circle, although make the silicon steel sheet that in the rough silicon steel sheet of its inner circle, projection is fallen in by plucking make its inner circle evenness better, but the burr of pull-out makes short circuit between stator punching, increase eddy current and the motor iron loss of stator, affect the quality of complete machine.
In addition, need mate the size of corresponding mold and width muscle according to the stator core internal diameter stamped out, such press fitting clamping fixture is more, and production cost is comparatively large, becomes to produce inefficiency.
Utility model content
The utility model needs the problem solved to be for above-mentioned the deficiencies in the prior art, and provides a kind of adjustable tensioner mold.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of adjustable tensioner mold, comprise tire core, width muscle, top board and lower platen, described tire core is columniform cylinder, its two ends are respectively equipped with the axle stretching out end face, the axle at tire core two ends is connected with top board and lower platen respectively by bearing, described width muscle is coated on the outer circumference surface of tire core, described width muscle is that split is arranged, at least comprise two pieces of circular arc-like blocks matched with the outer circumference surface of tire core, top board is fixedly connected with width muscle respectively by spring catch with lower platen, top board and the gap location between lower platen and width muscle are socketed with tire cover respectively, tire cover is the circle of circular ring type, tire cover is fixedly connected with lower platen with top board respectively.
Bolt is each passed through top board and the screwed hole on lower platen and is arranged on the screwed hole that tire overlaps on end face and is connected.
Bolt annular is distributed on top board and lower platen.
Spring catch annular is distributed on top board and lower platen.
The thickness of width muscle is configured according to the internal diameter of stator core.
Described width muscle comprises four pieces of circular arc-like blocks matched with the outer circumference surface of tire core.
Compared with prior art, the beneficial effects of the utility model are:
Keep tire in-core footpath constant adjustable tensioner mold of the present utility model, by changing the thickness of width muscle, make it the stator core adapting to different inner diameters, put it in the axis hole of stator core, rotate tire core stator core tensioner is fixed, avoid the stator core internal diameter caused due to interference fit and produce the problems such as burr, ensure the quality of stator core inner circle; After stator core completes and press-fits, then tire core is rotated dismounting; For the internal diameter of different stator core, while adopting identical tire core, select the width muscle of different-thickness to satisfy condition, decrease manufacture and the use of press fitting clamping fixture, also facilitate while press-fiting operation, also reduce the use of press fitting clamping fixture.
