Abstract
The utility model relates to a retraction apparatus of a prefabricated positioning shaft of motor rotor and bearing pressing machine. The retraction apparatus comprises a feeding installation shaft, a fixing seat and a locating shaft. The fixing seat coaxially fixes the locating shaft. The locating shaft is mounted on the installation shaft through the fixing seat which is fixed on an end face of the feeding installation shaft. The feeding installation shaft is provided with a coaxial inner through hole. A retraction seat is disposed in an inner hole of the feeding installation shaft in a coaxial guided manner. A spring is coaxially disposed in a groove arranged at an inner end of the retraction seat. The locating shaft is coaxially embedded in an outer end of the retraction seat in the inner through hole. The locating shaft is clamped into the inner hole of the feeding installation shaft by the fixing seat. An end face of the retraction seat in an inner end of the locating shaft is provided with an anti-rotation keyway. An outer rim surface of the locating shaft is coaxially provided with a keyway, and threaded holes are uniformly distributed in a plane of the keyway. The retraction apparatus has a certain buffering effect and a simple retraction principle, and is convenient to operate and easy to execute.
Description
Technical field
The utility model belongs to automated production field, relates to rotor bearing press, the backspace mechanism of the prefabricated locating shaft of especially a kind of rotor bearing press.
Background technology
The parts such as shaft sleeve are the vitals of the power transmission such as machine or equipment part, in the startup of equipment or machine and transmission, are bringing into play irreplaceable effect.But the axiality of bearing and axle sleeve is the important indicator that guarantees machine or the defeated performance of equipment dynamic.
In order to guarantee the accurate suit of product axle and axle sleeve, conventionally on pressing machine, can be provided with locating shaft, while press-fiting, first rotor is sleeved on locating shaft, then by displacement of pressing machine feeding, realize rotor with by the coordinating of complete product axle, still, the rotor on locating shaft can produce certain effect of inertia when the feeding along with the pressure head of pressing machine, make the moment that rotor coordinates with product axle produce impact, thereby reduce the precision of also cooperation and the qualification rate of product; Meanwhile, locating shaft, also can, along with rotor contacts and produces certain friction with the axle head of product axle with the cooperation of product axle, having reduced the precision on locating shaft surface, has affected the quality of fit of rotor and product axle simultaneously.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides that a kind of quality of fit is high, axiality is high, and can effectively guarantee product axial end, improves the backspace mechanism of the prefabricated locating shaft of electromotor rotor pressing machine of its qualification rate.
The technical scheme that the utility model technical solution problem adopts is:
The backspace mechanism of the prefabricated locating shaft of a kind of rotor bearing press, comprise feeding installation shaft, holder and locating shaft, holder is coaxially installed locating shaft, this locating shaft is that the holder by being fixed on feeding installation shaft end face is arranged in feeding installation shaft, described feeding installation shaft is shaped with coaxial inner via hole, this inner via hole is square through hole, four jiaos at square opening are shaped with fillet, in the endoporus of feeding installation shaft, coaxial guiding is provided with a rollback seat, the inner end of this rollback seat is equipped with a groove, in this groove, be coaxially installed with a spring, the coaxial setting-in locating shaft in rollback seat outer end in inner via hole, this locating shaft is installed in the endoporus of feeding installation shaft by holder.
And, be shaped with an anti-rotation keyway at the rollback seat end face of locating shaft inner end.
And, the coaxial keyway that is shaped with of outer edge surface of locating shaft, in this keyway plane, uniform interval is shaped with screwed hole.
Advantage of the present utility model and good effect are:
1, this backspace mechanism has certain cushioning effect, in the time that the rotor on locating shaft coordinates with the product axle being set with, first the axle head of product axle can contact with the axle head of locating shaft, and the other end of locating shaft is connected with spring, along with the displacement of feeding, locating shaft can be pushed up by the axle head of product axle, be that spring is compressed, inertia while effectively reducing pressing head of packing press due to feeding makes rotor to the moment impact producing in product axle engagement process, simultaneously, due to the elastic force effect of spring, make the locating shaft also can be to counter-force of product axle, rotor on locating shaft is fully coordinated with product axle, improve the precision coordinating.
2, to realize the principle of rollback simple for this backspace mechanism, in rollback groove, is provided with spring, and this spring is connected with one end of locating shaft, and then realize coordinating of rotor and axle by the elastic force effect of spring, easy to operate, easily execution.
Accompanying drawing explanation
Fig. 1 is axis sectional plan view of the present utility model;
Fig. 2 is right view of the present utility model;
Fig. 3 is that the A-A of Fig. 1 is to sectional view.
Embodiment:
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection range of the present utility model with this.
The backspace mechanism of the prefabricated locating shaft of a kind of rotor bearing press, comprise feeding installation shaft 1, holder 4 and locating shaft 6, holder is coaxially installed locating shaft, and this locating shaft is that the holder by being fixed on feeding installation shaft end face is arranged in feeding installation shaft.
Innovative point of the present utility model is:
Described feeding installation shaft is shaped with coaxial inner via hole, and this inner via hole is square through hole, is shaped with fillet at square opening four jiaos.In the endoporus of feeding installation shaft, coaxial guiding is provided with a rollback seat 3, and the inner end of this rollback seat is equipped with a groove, is coaxially installed with a spring 2 in this groove; The coaxial setting-in locating shaft in rollback seat outer end in inner via hole, this locating shaft is installed in the endoporus of feeding installation shaft by holder.
For radial location locating shaft, be shaped with an anti-rotation keyway 5 at the rollback seat end face of locating shaft inner end.
The coaxial keyway 8 that is shaped with of outer edge surface of described locating shaft, in this keyway plane, uniform interval is shaped with screwed hole 9.Keyway and screwed hole are for being fixedly connected with rotor or the axle sleeve that will coordinate.
