Abstract
Provided is a large motor stator silicon steel sheet tool device. A base, a locating shaft with flexible wheel discs, and an upper cover plate are mechanically connected in sequence. The locating shaft with flexible wheel discs comprises six flexible wheel discs which are mechanically connected with arc plates on the top. A lead screw and taper sleeves are mechanically connected in the middle. Stator silicon steel sheets just need preliminarily stacking in the tool device, and a system can automatically complete an adjusting operation. Workload and working time are reduced. The tool device can complete subsequent adjusting and laminating operation as long as the stator laminations are preliminarily aligned and put in the system. A locating key is fixedly connected with a second arc plate, and put-in and take-out are not needed, so operation is simple.
Description
Technical field: the utility model relates to a kind of large-size machine stator silicon steel sheet fitting device.
Background technology: along with the development of nuclear power technology, frock for motor stator silicon steel sheet requires also more and more higher, the quality that stator lasmination stacks is directly determining the performance of motor, existing mode is mainly manually to stack, though this mode can ensure just certain precision, but can not meet all large-scale required precision, moreover some large-size machines inside is not suitable for people and enters the line operate of going forward side by side, be difficult to again ensure precision in peripheral operation, so traditional frock that stacks has been difficult to meet present demand.
Summary of the invention: stack the defect of method for tradition, meet the demand of large-size machine high-performance and high accuracy, the utility model provides a kind of method can be adjusted stator silicon steel sheet after manually tentatively stacking, and makes it to stack precision higher.The utility model adopts following technical scheme: large-size machine stator silicon steel sheet fitting device,: comprise the locating shaft (12) of base (14), upper cover (11), the flexible disc (2) of band and drive assembly to form, base (14) is the cylindrical mesa of a hollow, on face, there is the through hole of connecting motor (17), be provided with the locating shaft (12) of jockey with the flexible disc (2) of connecting band around; Upper cover (11) is a circular thick cover plate, in have through hole, above put suspension ring (10), in order to complete integral lifting transport; Locating shaft (12) two ends of the flexible disc (2) of band are distributed with screwed hole, are connected respectively by bolt with base (14) with upper cover (11); Drive assembly to be positioned at base (14), drive the locating shaft (12) of flexible disc (2) flexible by motor (17) and reductor (16).
Operation principle of the present utility model is when putting into after silicon steel sheet, utilizes the positioning key in arc plate to locate, and prevents silicon steel sheet interformational sliding.Use the rotation of motor driving leading screw, make three tapered sleeves produce rectilinear motion along screw thread, via the inclined-plane of tapered sleeve, rectilinear motion is converted into the radial motion of flexible disc, the thrust while utilizing disc to stretch out is supportting silicon steel sheet just.
The utility model is all connected with tapered sleeve at leading screw two ends and centre, can produce thrust from three positions of upper, middle and lower.Two ends tapered sleeve has "T"-shaped protruding guide rail, and there is "T"-shaped indent guide rail at disc two ends, and two class guide rails match, corresponding up and down, can prevent the dislocation up and down of disc.In conventional operation mode, positioning key need manually insert in silicon steel sheet backlash after silicon steel sheet is placed again, for as the utility model for large-size machine stator, more need repeatedly layering to place, in the utility model, positioning key is connected on the second arc plate, do not need extra placement and taking-up, reduced workload.Upper cover can, by jockeys such as bolts after stator silicon steel sheet has laminated, will laminate the complete silicon steel sheet locking of stretching.Intermediate sleeve not only plays the role of positioning, and is also responsible for connecting upper cover and base simultaneously.Utilize and the linking of sleeve, can fixed cover, prevent upper cover generation transverse shifting.
Specific works process can be with reference to following example: first top cover is picked up, partial stator silicon steel sheet is positioned on fitting device base, silicon steel sheet is by manually tentatively stacking, utilize positioning key that stator silicon steel sheet is stabilized in outside flexible disc sleeve, rotated by motor driving leading screw afterwards, leading screw rotation makes both sides tapered sleeve move toward one another, and then drive flexible disc overhanging, arc plate outside flexible disc contacts with silicon steel sheet, silicon steel sheet is just being supportted, after hydraulic press compresses, shrink flexible disc, carrying out silicon steel sheet next time places, so repeatedly, after enough silicon steel sheets are just all supportted, cover upper cover plate, silicon steel sheet is fixed, can weld afterwards or carry out transport via suspension ring.
The beneficial effects of the utility model are: the error that can produce when making up people and stack stator silicon steel sheet by machinery, improve the motor accuracy of manufacture and overall performance, and reduce workload and operating time.Traditionally workman need to be as much as possible by artificial stator lasmination alignment stacked, then locate with positioning key.In the utility model, do not need stator lasmination stackedly as much as possible, only need put into system after preliminary alignment, fixture system can complete follow-up support just with laminate work, positioning key is connected on the second arc plate, does not need to put into and take out, operation is succinct.After just laminating for support, the operation such as generally weld on the spot traditionally, for the utility model for large-size machine, often need additionally to set up scaffold or support to carry out the processing such as the welding on stator lasmination top, in build process, also need to prevent that the stator silicon steel sheet complete with laminating stretching from coming in contact, prevent from destroying previous achievement.And in the utility model after stretching has laminated, can stator silicon steel sheet be locked in tooling machine via upper cover, can there is relative sliding and dislocation in each stator lasmination letter cloth, moment keeps previous stretching to laminate complete state, now can entirety be lifted by crane to transport via the suspension ring of upper cover and base, can conveniently complete the work such as accumbency, movement, can make staff select voluntarily to facilitate suitable place and attitude to carry out the operations such as follow-up welding, do not need the destruction of misgivings to previous achievement, and then increase work efficiency.
