Description
Technical field
The utility model belongs to motor manufacturing moulds of industrial equipment field, relates to a kind of adjustable cast-aluminum rotor quick-detachment dummy shaft frock, is particularly suited for the centrifugal processing of the cast-aluminum rotor of high-voltage motor product under the condition of high temperature.
Background technology
Current motor refers to a kind of calutron realizing electric energy conversion according to the law of electromagnetic induction or transmit, and the rotating part in motor is called rotor, is made up of parts such as rotor core, rotor windings, rotating shaft and fans.Rotor windings is not formed by insulated conductor coiling, but the threephase asynchronous be welded by aluminum strip or copper bar and short-circuited conducting sleeve is called squirrel-cage motor.Middle-size and small-size squirrel-cage asynchronous motor adopts cast aluminium mode to manufacture, and is by cast solids such as rotor conductor, short-circuited conducting sleeve and fans, is called cast-in aluminum squirrel cage formula rotor.It is compared with copper bar rotor, have processing simple, save man-hour, production efficiency is high; The design of slot shape of rotor, not by the restriction of copper bar shape, can be selected arbitrarily; The advantages such as the work performance of motor can be improved.Because middle size motor production lot is little, specification is many, rotor diameter is large, therefore, carrying out cast aluminium processing can not adopt extrusion process as micro-machine, can only adopt centrifuging process.Adopt centrifugal aluminum casting for rotor first punching will be inserted in dummy shaft, heating and thermal insulation after precompressed consolidation, then carry out centrifugal aluminum casting processing.Heating-up temperature will remain on 500 ~ 600 DEG C, iron core dummy shaft after processing due to temperature too high, in addition dummy shaft has weak point in configuration aspects, can not be taken off by rotor shaft hatch locking, with water accelerating cooling or must wait until nature cooling, dummy shaft could be taken out, so not only have impact on the service efficiency of dummy shaft, and need a large amount of water to cool, cause the waste of resource, moreover, because chilling is easy to cause, dummy shaft local overcooling causes flexural deformation, dummy shaft is scrapped.
Summary of the invention
The utility model provides a kind of dummy shaft frock of adjustable cast-aluminum rotor quick-detachment for solving in known technology the technical problem that exists, can under the prerequisite ensureing dummy shaft precision, after realizing rotor spun casting, the high temperature of dummy shaft takes out fast, eliminate time or the wasting of resources that causes of water-cooled of nature cooling, improve utilance and the degree of regulation of dummy shaft, decrease the destruction to environment, reduce enterprise's production cost.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
A kind of adjustable quick-detachment cast-aluminum dummy shaft frock, comprise adjusting rod, regulating block, dummy shaft, flow splitter, shunt, increase packing ring and block, it is characterized in that: the main body of described dummy shaft is a hollow circuit cylinder, two flaps are cutd open into from one end of cylinder centrally alignment, the other end connects, be provided with symmetrical square groove on it at the top of cylinder and be fitted with regulating block, the two ends of adjusting rod are connected with regulating block respectively, the outer surface of dummy shaft is equidistant is provided with fixing overstriking muscle, two overstriking muscle are wherein respectively equipped with the first positioning straight key mounting groove and the second positioning straight key mounting groove, first positioning straight key mounting groove and the second positioning straight key mounting groove there is associated positioning straight key respectively, described shunt coordinates with flow splitter, be arranged on the upper end of dummy shaft, described elevating pad snare is contained in dummy shaft lower end, increase packing ring and be provided with resigning hole, resigning hole is corresponding with positioning straight key position, described block is connected with dummy shaft by connecting bolt.
Described shunt is tapered shunting device.
The advantage that the utility model compared with prior art has and good effect are: its upper end of dummy shaft adopted due to the utility model is two flap-type structures, and lower end is connected, and can guarantee that dummy shaft bottom size is constant but top is adjustable; Because dummy shaft outer ring is not all contact axis hole, just fix overstriking muscle by the six roots of sensation and contact, reduce contact area, be more conducive to the taking-up of dummy shaft under heat expansion state; The utility model can reduce dummy shaft diameter fast by regulating dummy shaft diameter after cast-aluminum rotor processing, is directly taken out from rotor core by dummy shaft, saves the step of dummy shaft cooling.Simultaneously, dummy shaft of the present utility model can according to actual production iron core height, highly make up the difference in height of iron core height and dummy shaft by adding the superposition of increasing packing ring, makes iron core can compacting on dummy shaft, reach the object that an axle is multiplex, save frock cost.

Embodiment
For summary of the invention of the present utility model, Characteristic can be understood further, exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As shown in Fig. 1-6, a kind of adjustable quick-detachment cast-aluminum dummy shaft frock, comprise adjusting rod 10, regulating block 9, dummy shaft 1, flow splitter 2, shunt 3, increase packing ring 4 and block 6, described dummy shaft 1 is in hollow in one, its one end is distinguish, the other end is the dummy shaft of not distinguish, the main body of dummy shaft is a hollow circuit cylinder, under one end of cylinder centrally alignment, (not on earth) cuts open into two lobes, the other end connects, be provided with symmetrical square groove 12 on it at the top of cylinder and be fitted with regulating block 9, the two ends of adjusting rod 10 are connected with regulating block respectively, the equidistant six roots of sensation that is provided with of the outer surface of dummy shaft fixes overstriking muscle 8, two overstriking muscle are wherein respectively equipped with the first positioning straight key mounting groove 11 and the second positioning straight key mounting groove 11', first positioning straight key mounting groove and the second positioning straight key mounting groove there is associated positioning straight key 5 respectively, described shunt 3 coordinates with flow splitter 2, be arranged on the upper end of dummy shaft, the described packing ring 4 that increases is sleeved on dummy shaft lower end, increase packing ring and be provided with resigning hole 13, resigning hole is corresponding with positioning straight key 5 position, described block 6 is connected with dummy shaft by connecting bolt 7.Described shunt is tapered shunting device.
When using the utility model, casting aluminum rotor iron core according to manufacturing adjusts the quantity increasing packing ring, then adjustment in use bar regulates the external diameter of dummy shaft, again shunt is connected with dummy shaft in order with flow splitter and dummy shaft is inserted in punching, folded up to after requiring until punching, by block 6 and increase packing ring 4 and be inserted in dummy shaft and press-fit, reach after specified value until pressure, locking connecting bolt 7, bit platform is allowed due to centrifuge platform being designed with, the part that dummy shaft bottom can be exceeded punching allows into counterdie, thus reach the effect that a dummy shaft is suitable for multiple height iron core.The quantity increasing packing ring 4 can be one, also can be multiple, the superposition quantity increasing packing ring is relevant with the height of actual production cast aluminium iron core, by calculating the difference in height of dummy shaft and cast aluminium iron core, what use right quantity increases packing ring, to reach the object of precompressed consolidation, thus realize a dummy shaft and manufacture multiple height iron core, improve dummy shaft utilance.
