Abstract

The utility model discloses a detachable clamping fixture structure, belonging to the generator manufacture field. The detachable clamping fixture structure comprises a fixture body, a core shaft, a core shaft fixing plate, an upper pressure plate device, and a lower bottom plate device, wherein the fixture body and the core shaft are sleeved together, and are fixedly connected through the core shaft fixing plate; a stator punching sheet is sleeved outside the fixture body and is fixed through the upper pressure plate device and the lower bottom plate device; and the outside diameter of the lower bottom plate device is greater than that of the stator punching sheet. By adopting the improved detachable clamping fixture structure, enough support force is provided for the stator punching sheet, so as to effectively guarantee the planeness of the stator punching sheet during pressing and improve the quality of the stator punching sheet.

Description

A kind of detachable positioner structure
Technical field
The utility model relates to a kind of detachable mold structure-improved, is applicable to that all adopt the stator punching of cramp and weldering muscle mode to press-fit, and especially in the bigger occasion of motor center height, belong to generator and make the field.
Background technology
When the stator punching that punching out is good laminated, base plate, carcass, mandrel, mandrel fixed head are installed together by bolt became mold earlier, stator punching is enclosed within on the carcass in order again, compresses by briquetting is fastening.In the prior art, base plate is divided into two parts by a light rounding plate, and the external diameter of base plate is slightly less than the stator punching external diameter, when welding cramp or welding stator muscle, because base plate is that a light circle can not be stepped down fully, bring difficulty for this operation, simultaneously the external diameter of base plate is slightly less than the stator punching external diameter and can not supports the stator punching of being pressed fully, the part that causes stator punching and lower shoe device contact-making surface to stretch out is outstanding downwards under active force, can not guarantee the flatness of stator punching, thereby reduce the quality of product.
Summary of the invention
The utility model is at deficiency of the prior art, a kind of detachable mold structure-improved device is provided, in the process of compacting stator punching, enough support forces are provided for the stator punching, and can when welding cramp or stator muscle, directly allow open position, thereby the quality of the stator core product after having guaranteed to laminate.
For realizing above technical purpose, the utility model will be taked following technical scheme:
A kind of detachable positioner structure, comprise carcass, mandrel, mandrel fixed head, top board device and lower shoe device, described carcass, mandrel interlock, and it is fixedly connected by described mandrel fixed head, described carcass outside socket stator punching is also fixedlyed connected with the lower shoe device by described top board device, and the external diameter of described lower shoe device is greater than the stator punching external diameter.
Described top board device comprises first pressing plate, second pressing plate and briquetting, described first pressing plate, one end is fixed on the described carcass, and the other end is fixedlyed connected with described briquetting one end, described second pressing plate of connection that the briquetting other end is conflicted, the described stator punching of connection that described second pressing plate is conflicted.
Described lower shoe device comprises first base plate and second base plate, and cooperating between described first base plate and second base plate is the ladder matched in clearance, and is integral planar, and the aperture is greater than the diameter of carcass on the described first base plate shoulder hole.
The outermost light disc of described first base plate is offered slot to make way.
The quantity of described slot to make way is the quantity of welding cramp or stator muscle.
According to above technical scheme, can realize following beneficial effect:
By adopting a kind of detachable mold improved device described in the utility model, can be in the process of compacting stator punching by this mold, stator punching all is on the lower shoe device, offer the enough support forces of stator punching, offer slot to make way at the lower shoe device, the position of cramp or stator muscle can be directly abdicated, the flatness of the stator punching that suppresses can be more effectively guaranteed.
Description of drawings
Fig. 1 is the structure assembly drawing that stator punching described in the utility model press-fits institute's use mold;
Structural front view, the vertical view of Fig. 2 lower shoe device described in the utility model.
Wherein, 1, carcass, 2, mandrel, 3, first pressing plate, 4, briquetting, 5, second pressing plate, 6, first base plate, 61, aperture on the shoulder hole, 62, aperture under the shoulder hole, 63, slot to make way, 64, the first base plate external diameter, 7, bolt, 8, second base plate, 9, mandrel fixed head, 10, bolt, 11, stator punching.
Embodiment
Accompanying drawing discloses the structural representation of a preferred embodiment of the related detachable mold of the utility model improved device without limitation, explains the technical solution of the utility model below with reference to accompanying drawing.
Shown in Figure 1, detachable mold improved device described in the utility model, comprise carcass 1, mandrel 2, lower shoe device, top board device, mandrel fixed head 9, mandrel 2 utilizes bolt 10 fixing with carcass 1 by mandrel fixed head 9, the lower shoe device is positioned at the below of carcass 1, and the stator punching 11 on the supporting carcass 1 is fixing with carcass 1 by bolt 7.The top board device comprises that first pressing plate, 3, the second pressing plates 5 and briquetting 4, the first pressing plates 3 fix with carcass 1 upper end, and described briquetting 4 is set in the lower end of first pressing plate 3, and described second pressing plate 5 is set in the lower end of briquetting 4.
Shown in Figure 2, described lower shoe device comprises first base plate 6 and second base plate 8, first base plate 6 and second base plate 8 are split to form by milling processing by a full circle steel plate respectively, guaranteeing that first base plate 6 and second base plate 8 can cooperatively interact is combined into a full circle steel plate, wherein the faying face of first base plate 6 and second base plate 8 is stepped, 61 is aperture on the shoulder hole, and 62 is aperture under the shoulder hole.Last aperture 61 when first base plate, 6 shoulder holes are installed is slightly larger than carcass 1 diameter of bore.The first base plate external diameter 64 is slightly larger than the external diameter of stator punching, gets its diameter and is the best greater than value at 6 ~ 10mm.The width of slot to make way and the degree of depth are greater than the relative dimensions of concrete cramp or stator muscle.
Removal carcass 1 separates second base plate 8 by bolt 7 with carcass, remove bolted part, by pull-down device, carcass 1, mandrel 2, second base plate, 8 integral body is moved down, and reaches the purpose of moving back tire.
In sum, use this to implement novel described a kind of detachable mold improved device, not only can improve the production efficiency of stator punching in lamination process effectively, and the lower shoe device is optimized, the flatness of the stator punching that assurance suppresses has more effectively improved the stator punching quality.
