Abstract
The utility model relates to a stacking mould. The stacking mould comprises a box type mould base with chamfer angles and is formed by connecting four symmetrical side plates, a top plate and a bottom plate, wherein the side plates are convex, the width of a convex positioning rib corresponds to the width of a laminated opening groove, V-shaped positioning blocks are fixedly arranged on the four sides of the bottom surface of the top plate, a V-shaped groove or a V-shaped tenon is arranged on each positioning block, grooves or tenons correspondingly connected with V-shaped positioning blocks are arranged at the top of the side plates; a through hole is formed in the middle of the top plate, a pressure plate is fixed in the through hole, a mandrel fixedly connected to the bottom plate is sleeved into the pressure plate, a compression nut is in threaded connection with the upper end part of the mandrel, and the top plate is movably fixed on the side plates by the compression nut. The stacking mould can be positioned accurately and is convenient to demould.
Description
Technical field
The utility model relates to the motor processing technique field, especially a kind of overlapping mold for core lamination stack.
Background technology
For avoiding eddy current, stator core is laminated by stalloy and forms, and traditional carvel built positioning accuracy is not high.Existing device for the lamination location, be generally fixed structure, namely utilize a box mould to position, press box, the lamination of iron core are superposeed around box mould, but its shortcoming is because affected by welding stress and welding after-contraction, when the stator demoulding, needing larger external force to make its separation, have a strong impact on production efficiency, also can increase the stator deformability amount.
The utility model content
The purpose of this utility model is the overlapping mold that a kind of accurate positioning is provided, is convenient in demoulding.
The purpose of this utility model is finished by following technical solution, overlapping mold, comprise the box die holder with chamfering, connected and composed by the same top board of the side plate of four symmetries, base plate, described side plate is convex, and the positioning bar width of described protrusion is corresponding with the lamination openings groove, it is characterized in that: described top board bottom surface four sides are installed with the V-arrangement locating piece, described locating piece is provided with v-depression or V-arrangement tenon, and described side plate top is provided with groove or the tenon with the corresponding connection of V-arrangement locating piece; Has through hole in the middle of the described top board, be connected with pressing plate in the through hole, be set with the mandrel that is fixed on the base plate in the described pressing plate, this mandrel upper end clamp nut that has been threaded, this clamp nut is fixed on roof movement on the side plate.
Described mandrel middle part has the hole that two 90 degree intersect, and each hole is equipped with the extension spring of the described pair of side plates of traction.
Described mandrel top is connected with pressing plate by flat key.
Described mandrel top is provided with the suspension ring for lifting.
The utility model carries out assembling and positioning by the side plate with positioning bar to lamination, when preparing closed assembly, first clamp nut is compressed to make with top board and the side plate of V-arrangement locating piece and fix, then, successively around laminating, then former is placed in the corresponding lamination slot and welding press box, lamination.After stator is finished, unclamp clamp nut, mandrel drives top board by clamp nut and the V-arrangement locating piece moves up, cause the V-arrangement locating piece to leave side plate, at this moment side plate is in relaxed state, and the lifting of regulating simultaneously mandrel just can make extension spring traction side plate move forward and backward, at this moment, stator has been easy to the demoulding.The utility model accurate positioning is convenient in demoulding.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that overlapping mold cooperates with lamination.
Embodiment
Below in conjunction with accompanying drawing the utility model is done detailed introduction:
As shown in Figure 1, 2: overlapping mold, comprise the box die holder with chamfering, side plate 1 by four symmetries connects and composes with top board 2, base plate 3, described side plate is convex, positioning bar 4 width of described protrusion are corresponding with lamination 5 open slots, described top board bottom surface four sides are installed with V-arrangement locating piece 6, and described locating piece is provided with v-depression 7 or V-arrangement tenon 8, and described side plate top is provided with groove or the tenon with the corresponding connection of V-arrangement locating piece; Have through hole 9 in the middle of the described top board, be connected with pressing plate 10 in the through hole, be set with the mandrel 11 that is fixed on the base plate in the described pressing plate, described mandrel top is by flat key 12 affixed pressing plates, this mandrel upper end clamp nut 13 that has been threaded, this clamp nut is fixed on roof movement on the side plate.Described mandrel middle part has the hole 14 that two 90 degree intersect, and each hole is equipped with the extension spring 15 of the described pair of side plates of traction.Described mandrel top is provided with the suspension ring 16 for lifting.
