Description
Technical field
The utility model belongs to motor manufacturing moulds of industrial equipment field, relates to the localization tool that a kind of cast-aluminum rotor press-fits mandrel, is particularly useful for the cast-aluminum rotor after to die casting and press-fits mandrel while hot.
Background technology
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 that aluminum strip or copper bar and short-circuited conducting sleeve are welded is called squirrel-cage motor.Middle-size and small-size squirrel-cage asynchronous motor adopts cast aluminium mode to manufacture, and by cast solids such as rotor conductor, short-circuited conducting sleeve and fans, is called cast-in aluminum squirrel cage formula rotor.Compare with copper bar rotor, have processing simple, save man-hour, labor productivity 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 micro-machine batch is large, specification is fixed, rotor diameter is moderate.Therefore, less employing centrifuging process processed by cast aluminium, adopts extrusion process more.After iron core die casting, mandrel can be pressed into iron core, existing last item mode is mainly divided into two kinds: normal temperature last item and iron core heating last item, generally selects different last item modes according to iron mandrel's hole size, when the iron core that manufacture axis hole size is bigger than normal, the mode of heating last item is usually adopted to process.
Heating last item can make axis hole become greatly due to the reason diameter of heat expansion, and smoothly mandrel can be pressed into axis hole, axis hole can not be scratched simultaneously, save the last item time, the plant equipment used is also relatively simple.But owing to there is no special equipment, after can not making full use of die casting, cast aluminium solidifies the time of lasting heat release, as designed a kind of special positioning fixture that mandrel can be pressed into iron core, and reach cast aluminium after iron core die casting solidify continue heat radiation time in mandrel can be pressed into the object of iron core, save the energy waste that post bake causes, increasing work efficiency is goal of the invention.
Summary of the invention
The utility model for solve in known technology the technical problem that exists and a kind of reasonable in design is provided, can effectively utilize die casting after cast aluminium solidify lasting heat release time, avoid mandrel to sink, displacement, can improve and produce quick-acting rate, reduce a kind of localization tool press-fiting mandrel for cast-aluminum rotor of 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 localization tool press-fiting mandrel for cast-aluminum rotor, comprise location panel, connect dull and stereotyped, sleeve pipe, the upper end of described sleeve pipe is fixed with a connection flat board, lower end is fixed with location panel, is provided with an opening be communicated with sleeve pipe in the middle part of described location panel, and the diameter of location panel is greater than the diameter of cast-aluminum rotor axis hole, described connection flat board is provided with screw counter bore, it is furnished with screw, and the outside of described sleeve pipe is evenly provided with the auxiliary plate 4 of at least one piece, and described auxiliary plate is also provided with hole for hoist.
The utility model compared with prior art has significant advantage and beneficial effect:
Because the utility model adopts unitary design, being linked together by sleeve pipe and disc by two planes, by guaranteeing the depth of parallelism of two planes, guaranteeing mandrel and the cast-aluminum rotor behavior error when press-fiting; Mandrel is connected by screwed hole with tool, and contact-making surface is that mandrel thread hole end surface is connected plane with tool, and the gap between mandrel and sleeve pipe ensures that mandrel can not collide with in the process press-fited, and that avoids mandrel surface knocks trace and scuffing; The utility model can after coordinating with mandrel and pressing fit into cast-aluminum rotor, the location panel of tool and the punching face compacting of cast-aluminum rotor are developed, can ensure that mandrel can not sink due to own wt, avoid mandrel assembly deflections, reach the effect of protection mandrel and positioning core axle position simultaneously; Make it possible to be pressed fit into by mandrel fast the cast-aluminum rotor that just die casting is come out of the stove, avoid temperature of rotor to decline, reach the object press-fited with furnace temperature, eliminate the energy waste that post bake causes, save the energy and greatly improve work task efficiency.
