Description
Technical field
The utility model belongs to the electric device for valve technical field, particularly relates to a kind of electric device inner electric machine stator dismounting specific purpose tool.
Background technology
For electric device for valve, its definite purpose motor should meet the load characteristics of valve, thereby its detent torque is big, starting current is big, moment of inertia is little, short-term operation, no cooling device etc.Because electric device for valve applying working condition condition is very complicated, stator coils of motor burn or the damage of other reason also takes place once in a while, need field service to change.The inner electric machine stator structure that (below the 300N.m output torque) adopted for little torque electric device, its motor housing is exactly the part of electric device main box, and relatively difficulty is changed sometimes in field service.
The known technology electric device for valve is as shown in Figure 1 with motor built-in type stator core construction: motor stator core 1 and less the cooperating in 2 employing gaps of electric device casing, and concentric to guarantee its installation site and armature spindle.There is Milling Process to become the shallow slot of the certain width and the degree of depth on the hole wall of electric device casing, processes a screw with this groove vertical position.During assembling stator core is pushed the electric device casing and will push fixing chuck plate 3 again and push in the shallow slot, be screwed into trip bolt 4 and it is fixed when clamp guarantees stator core work and in the hole of electric device casing, do not rotate.The deficiency of its existence is: when electric device longer service time; And field working conditions inclement condition (like high temperature, high humidity) can cause between stator core and the electric device casing and produce corrosion; This situation then is difficult to from the electric device casing, take out stator core with manpower, adopts other general utility tool also can't realize the dismounting of stator core.
Summary of the invention
The utility model provides a kind of simple in structure, easy to carry and easy-to-dismount electric device inner electric machine stator dismounting specific purpose tool for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Electric device inner electric machine stator dismounting specific purpose tool; It is characterized in that: comprise fairlead, have guide holder, thrust post, push rod, supporting pad, bracing frame and the central shaft of centre bore on it; Be shaped on a plurality of five equilibrium grooves on the circumference of the axial last end of said guide holder; Said fairlead directly upwards is shaped on a plurality of five equilibrium installing holes, in the said fairlead guide holder is installed, and in the five equilibrium installing hole of fairlead, the thrust post is housed; Be provided with push rod and supporting pad through securing member on said fairlead one end face, install central shaft on said guide holder centre bore and the supporting pad and through nut check.
The utility model can also adopt following technical scheme:
Be shaped on four five equilibrium grooves on the circumference of the axial last end of said guide holder.
Each five equilibrium groove on the said guide holder is the five equilibrium groove that an end is shaped on circular arc.
Said fairlead directly upwards is shaped on four five equilibrium installing holes.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme; Promptly make the endoporus of this dismounting specific purpose tool and stator core prop up stretching through the rotation nut; At electric device for valve casing end face fulcrum is installed; With nut rotation pulling stator core, make to produce between stator core and the electric device casing and become flexible, and then accomplish dismounting again.This dismounting specific purpose tool is particularly useful for the maintenance of valve definite purpose motor structure, its simple in structure, easy to carry, easy operating.

Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 2-Fig. 6, electric device inner electric machine stator dismounting specific purpose tool comprises fairlead 4, has guide holder 3, thrust post 5, push rod 6, supporting pad 7, support column 8, bracing frame 9 and the central shaft 10 of centre bore on it.Be shaped on a plurality of five equilibrium groove 3-1 on the circumference of said guide holder 3 axial last ends, in the present embodiment, be shaped on four five equilibrium grooves on the circumference of the axial last end of said guide holder, said each five equilibrium groove is the five equilibrium groove that an end is shaped on circular arc.Said fairlead directly upwards is shaped on a plurality of five equilibrium installing hole 4-1, and in the present embodiment, said fairlead directly upwards is shaped on four five equilibrium installing holes, and branch grooves such as the diameter in hole and guide holder are measure-alike.In the said fairlead 4 guide holder 3 is installed, in each five equilibrium installing hole 4-1 of fairlead, thrust post 5 is housed, the outside dimension of fairlead is smaller than the internal diameter of stator core.Through securing member push rod 6 and supporting pad 7 are housed on said fairlead one end face, install central shaft 10 on said guide holder centre bore and the supporting pad and pass through nut 11 lockings, in the present embodiment, said supporting pad 7 is the steel supporting pad.
The operation principle of the utility model is:
See also Fig. 7; Four thrust posts are respectively charged in the five equilibrium installing hole 4-1 on the fairlead; And stretch in the groove of guide holder, then said modules is stretched in the hole of stator core together with push rod, supporting pad, central shaft, the nut of screwing near supporting pad will make guide holder and fairlead produce displacement; Mill flatly on central shaft top, it does not rotate tool constraint.Because the circular arc of five equilibrium groove causes the thrust post to produce expanding outwardly motion on the guide holder, and with the inner hole wall of four some push-tight stator cores.This moment, said modules and stator core became one.Again support column 8 is screwed in the fixing threaded hole of the End cover for motor on the electric device casing 2 to form fulcrum; Bracing frame 9 is packed on the central shaft 10 and is placed on the support column 8; The nut 11 of screwing, at this moment, operating personnel move extracting tool and can stator core together be pulled out.
After each part of the utility model disintegrates just with carry, be well suited for the maintenance personal and at the scene the electric device motor repaired or replaced.
