Description
Technical field: the present invention 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 directly decides the performance of motor, existing mode mainly manually stacks, though this mode can ensure just certain precision, but all large-scale required precision can not be met, moreover some large-size machine inside is not suitable for people and enters line operate of going forward side by side, be difficult to again ensure precision, so traditional frock that stacks has been difficult to satisfied present demand in peripheral operation.
Summary of the invention: the defect stacking method for tradition, meets the demand of large-size machine high-performance and high accuracy, the invention provides a kind of method, can be adjusted by stator silicon steel sheet after manually tentatively stacking, and makes it to stack precision higher.The present invention adopts following technical scheme: a kind of large-size machine stator silicon steel sheet fitting device, described device comprises base (15), upper cover (12), is with the locating shaft (13) of disc (2) and drives assembly, base (15) is the cylindrical mesa of a hollow, face there is the through hole of connecting motor (17), be provided with jockey with the locating shaft of connecting band disc (2) (13) around; Upper cover (12) is a circular thick cover plate, in have through hole, above put suspension ring (11), in order to complete integral lifting transport; Locating shaft (13) two ends of band disc (2) are distributed with screwed hole, are connected respectively by bolt with base (15) with upper cover (12); Assembly is driven to be positioned at base (15), the disc (2) in the locating shaft (13) of disc (2) is driven to stretch by motor (17) and reductor (16), the locating shaft (13) of band disc (2): to be made up of leading screw (7), upper tapered sleeve (1), lower tapered sleeve (9), band the first arc plate (3) of positioning spline, the second arc plate (8), sleeve (6), positioning key (10), middle tapered sleeve (5), skewback (4) and the disc (2) not with positioning spline; Sleeve (6) is simultaneously for locating shaft (13) provides overall location; Leading screw (7) is arranged in sleeve (6), coaxial with sleeve (6); Leading screw (7) two ends connect upper tapered sleeve (1) and lower tapered sleeve (9), and upper and lower tapered sleeve has "T"-shaped protruding guide rail; Be threaded connection middle tapered sleeve (5) in the middle of leading screw (7), middle tapered sleeve (5), with keyway, is placed with skewback (4) in keyway; Disc (2) is placed in sleeve (6), be positioned between sleeve (6) and leading screw (7), disc (2) outside is protruding stretches out from the through hole sleeve (6) wall, protruding outside is connected with the first arc plate (3), the second arc plate (8), angle 60 ° between two between disc, there is "T"-shaped indent guide rail at disc (2) two ends, two ends guide rail matches with upper tapered sleeve (1), lower tapered sleeve (9) tapered sleeve, between can mutually slide, is connected with bolt with skewback (4) in the middle of disc (2).
Operation principle of the present invention is after putting into silicon steel sheet, utilizes the positioning key in arc plate to locate, prevents silicon steel sheet interformational sliding.Use motor driving leading screw to rotate, make three tapered sleeves threadingly produce rectilinear motion, be the radial motion of disc via the inclined-plane of tapered sleeve by transform linear motion, thrust when utilizing disc to stretch out by silicon steel sheet support just.
The present invention is all connected with tapered sleeve at leading screw two ends and centre, can produce thrust from upper, middle and lower three positions.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 manually need insert in silicon steel sheet backlash after silicon steel sheet is placed again, for such as the present invention for large-size machine stator, repeatedly layering is more needed to place, in the present invention, positioning key is connected on the second arc plate, does not need extra placement and taking-up, decreases workload.Upper cover by jockeys such as bolts after stator silicon steel sheet has laminated, will can 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 refer to following example: first picked up by top cover, partial stator silicon steel sheet is positioned on fitting device base, silicon steel sheet is by manually tentatively stacking, positioning key is utilized to be stabilized in by stator silicon steel sheet outside disc sleeve, rotated by motor driving leading screw afterwards, leading screw rotates and makes both sides tapered sleeve move toward one another, and then drive disc overhanging, arc plate outside disc contacts with silicon steel sheet, by silicon steel sheet support just, after hydraulic press compresses, shrink disc, carry out silicon steel sheet next time to place, so repeatedly, enough silicon steel sheets are all supportted just, cover upper cover plate, silicon steel sheet is fixed, can carry out afterwards welding or carrying out transport via suspension ring.
The invention has the beneficial effects as follows: made up the error that can produce when people stacks stator silicon steel sheet by machinery, improve motor manufacturing precision and overall performance, decrease workload and operating time.Workman needs manually to be alignd by stator lasmination as much as possible and stacked traditionally, then locates with positioning key.Do not need stator lasmination stacked as much as possible in the present invention, after only needing preliminary alignment, put into system, 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 taking-up, and operation is succinct.After support is just laminated, generally carry out the operations such as welding on the spot traditionally, for the present invention for large-size machine, often need additionally to set up scaffold or support to carry out the process such as the welding on stator lasmination top, in build process, also needing to prevent the stator silicon steel sheet complete with laminating stretching from coming in contact, preventing from destroying Previous work achievement.And in the present invention after stretching has laminated, stator silicon steel sheet can be locked in tooling machine via upper cover, relative sliding and dislocation can be there is in each stator lasmination letter cloth, moment keeps previous stretching to laminate complete state, now via the suspension ring of upper cover and base, entirety can be carried out lifting to transport, can conveniently complete the work such as accumbency, movement, staff can be made to select to facilitate suitable place and attitude to carry out the follow-up operation such as to weld voluntarily, do not need the destruction of worrying to Previous work achievement, and then increase work efficiency.
