Abstract
The invention discloses an expansion mould type motor stator core pressing mould applied to the power field. The expansion mould type motor stator core pressing mould applied to the power field mainly comprises a base, an expansion block, an expansion core (4) and an inner rod (5), wherein the bottom of the inner rod (5) is fixed to the center of the base (1); the expansion core (4) is installed on the inner rod (5) in a sleeved mode; the expansion core (4) is sleeved with the expansion block (3) and a stator core (6) to be pressed; a cramp (2) is fixed to the upper portion of the base (1); the inner diameter of the cramp (2) is greater than the outer diameter of the stator core (6). The expansion mould type motor stator core pressing mould applied to the power field can achieve the purpose of smoothening the inner cylindrical surface of the stator core, through optimal design, the defect of uneven stress of original manual control can be overcome, and mechanical operation of the operation process is achieved; through the structures of a pressing board, a spring, a sleeve and the like, the purposes of avoiding deformation and preventing the stator core from loosening are achieved in the pressing process of the inner cylindrical surface of the core, and the quality of the core is effectively ensured.
Description
Technical field
The present invention relates to field of electrical equipment, specifically refer to a kind of expanding type motor stator core press mounting die that is applied to power domain.
Background technology
Stator core manufacture method in motor is all generally to press together with punching and cramp, and the stator cores that use straight channel type to press-fit in prior art more, the mould using in traditional manufacturing process is to use screw mandrel to be rotated down mostly, make mode that expansion core presses down with screw mandrel promote expansion block and outwards push iron core, owing to adopting the mode of manpower extruding expansion core, make expansion block can not have enough strength extruding iron cores, can not effectively realize the object of smooth iron core inner headed face.Can not rationally be controlled because iron core in extrusion process is stressed, iron core is easily produced and be out of shape the phenomenons such as loosening simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of expanding type motor stator core press mounting die that is applied to power domain, can effectively overcome above-mentioned defect, when effectively realizing stator core inner cylinder face smooth, can effectively prevent the stress deformation of iron core, and realize the mechanized operation of smooth stator core.
The present invention is achieved through the following technical solutions: a kind of expanding type motor stator core press mounting die that is applied to power domain, mainly formed by base, expansion block, expansion core, interior bar, described interior bar bottom is fixed on base center, described expansion core is sleeved on interior bar, described expansion block is sleeved on expansion core outside, stator core to be press-fited is sleeved on expansion core outside, is also fixed with cramp above described base, and described cramp internal diameter is greater than stator core external diameter.
Further, for realizing better the present invention, between described expansion block bottom and base, flexible rubber circle is installed.
Further, for realizing better the present invention, be set with successively from bottom to top pressing plate, spring, sleeve pipe on bar in above described expansion core.
Further, for realizing better the present invention, be provided with through hole on described interior bar top.
Further, for realizing better the present invention, below described expansion core, packing ring is installed.
Further, for realizing better the present invention, be set with supporting seat on bar in below described expansion core.
The present invention compared with prior art, has following beneficial effect:
(1) the present invention can realize the object of smooth stator core inner cylinder face, and by optimal design, can overcome the unbalance stress defect of original hand-guided, realizes the mechanization operation to operating process;
(2) the present invention is by structures such as design pressing plate, spring, sleeve pipes, can, realizing during iron core inner cylinder face is press-fited to process the object that avoid distortion, prevent core slackness, effectively ensure the quality of iron core.
