Background technology
At present, in high pressure, wind power motor manufacturing, quality and the operational reliability of motor producer in order to improve motor, stator and rotor punching jet-bedding generally adopts axis hole+keyway positioning process, to guarantee that punching laminates the back grooved, keyway is neat.As shown in Figure 1: jet-bedding processing punching positioner commonly used, the positioning disk 2 in tape spool hole in the middle of comprising, one end be positioned at that described positioning disk 2 axis holes and positioning disk 2 be in transmission connection positioning core axle 3 and the nut 4 that is threaded with described positioning core axle 3, during dismounting with upwards turns of nut 4, nut 4 upper surfaces promote positioning disk 2 lower surfaces, can withdraw from positioning disk 2, positioning core axle 3 centers are through hole, adopt M16 bolt 16 to be connected and fixed with board.Present most of electrical machinery plant and motor stamping professional production producer, positioning disk 2 is in transmission connection with positioning core axle 3 and adopts 10*8 flat key 15 location to be in transmission connection.This transmission mode only is applicable to that Y355 is following less than φ 148 axis hole punching jet-bedding transmissions.The high-voltage motor rotor shaft hatch is generally bigger, and maximum reaches φ 930.Big like this positioning disk rotator inertia, moment of torsion are big, depend merely on the flat key 15 location transmissions of a 10*8, obviously can not satisfy the product quality requirement.Often flat key 15 and positioning core axle 3 keyways are very easily sprained, and the grooved equal indicative is uncontrollable, has a strong impact on product quality and production efficiency.Cause frock to damage simultaneously, need often more to renew frock, increase production cost, reduce productivity effect, this being in transmission connection is not suitable for high pressure, the requirement of wind power motor stator and rotor punching notching process.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of under the big situation that the positioning disk rotator inertia is big, moment of torsion is big, still can effectively transmit moment of torsion between positioning disk and mandrel, and non-damageable jet-bedding processing punching positioner.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of jet-bedding processing punching positioner, the positioning disk in tape spool hole in the middle of comprising, one end is positioned at the positioning core axle of described positioning disk axis hole and the nut that is threaded with described positioning core axle, described nut is fixedlyed connected with positioning disk, and described nut and positioning core axle are by the jacking mechanism radial location.
Nut is connected with positioning disk with alignment pin by set bolt.
Described jacking mechanism comprises withstanding tight block and puller bolt, described nut inboard is provided with groove, described withstanding tight block is positioned at described groove, contain on described withstanding tight block and the sidewall that described positioning core axle contacts with described positioning core axle on the thread of threads engaged, puller bolt passes nut described withstanding tight block is held out against on the positioning core axle sidewall.
Described positioning core axle two ends are respectively equipped with upper screwed hole and following screwed hole.
Compare with prior art, the utility model has the advantages that:
1, the utility model is fixed (be convenient to dismounting simultaneously again, change) with positioning core axle and nut by jacking mechanism, positioning disk is fixedlyed connected with nut, reach positioning disk and positioning core axle and form one, effectively transmit at a high speed towards rotation torque, solve the big fragile frock problem of big positioning disk moment of torsion, guaranteed motor production and reliability of operation.The utility model processing is simple, and easy to operate, interchangeability is strong, and in motor stator and rotor punching jet-bedding process, the grooved equal indicative is effectively controlled, and improves product quality and production efficiency greatly.
2, positioning disk is connected by alignment pin and set bolt with nut, and alignment pin can effectively transmit high speed towards rotation torque, and set bolt is used for locking thread.
3, since the withstanding tight block sidewall be provided with positioning core axle on the thread that is complementary of screw thread, when puller bolt holds out against withstanding tight block on the positioning core axle sidewall, be not easy to damage the screw thread on the positioning core axle, and very close to each other between withstanding tight block and positioning core axle, hold out against effective.
4, screwed hole is used for being connected and fixed by being screwed into bolt and board down, upper screwed hole is screwed into bolt, be used for the change bit positioning core axle, lift by crane during dismounting, solve former location disassembling mandrel and need beat positioning core axle, the problem of 1: 20 taper fit face of fragile positioning core axle and board is increased work efficiency simultaneously.
