Description
Technical field
The utility model relates to a kind of new tool, for the dismounting technique of rearmounted exciter, is specially the extracting tool of rearmounted exciter rotor in electrical micro-machine.
Background technology
Traditional exciter rotor dismounting technique be full manual operations, two people one group, and people pins, fixed electrical machinery, and the first rear end cap of another people is removed, again by overall for rotor taking-up, finally removed by exciter rotor.But in order to tackle the demand in market, meet the requirement of client to motor performance and weight, rear end cap is placed between exciter rotor and main pole rotor by some electrical micro-machine, and the exciter rotor of this type motor can not dismantle the work step execution of technique obviously by tradition, and rotating shaft and exciter rotor belong to interference fit, need larger removal force, pull simply manually and can not reach the object be separated with rotating shaft by exciter rotor easily; The size of electrical micro-machine is less, and space availability ratio is high, and force application location is few.Therefore, the extracting tool developing rearmounted exciter rotor in a kind of electrical micro-machine is needed.
Summary of the invention
The purpose of this utility model is the extracting tool providing rearmounted exciter rotor in a kind of electrical micro-machine, and this instrument is fixed on exciter rotor, is exerted a force by countershaft, the dismounting of rearmounted exciter rotor in electrical micro-machine can be realized, simple to operate, easy to use, do not damage the parts of electrical micro-machine.
The technical solution of the utility model is: the extracting tool of rearmounted exciter rotor in electrical micro-machine, mainly comprises the combination of dismounting dish, spacer shell, set bolt, push rod and force; It is characterized in that: dismounting dish is containing disk and lining two groups of component units, and have 4 apertures and 1 macropore in disk, hole centered by the hole that wherein diameter is larger, all the other 4 apertures are fixed bolt hole; Lining is welded on disc centre hole; Spacer shell is containing two holes, and a hole is lead wire accommodation hole, and another hole is that hole puted forth effort by push rod; Set bolt, through 4 apertures of dismounting dish, 4 ventilation holes of exciter rotor, with exciter rotor hold-down nut clamping, is fixed; There are screw thread, opposite side perforate in push rod side; Force combination is made up of force application rod and nut, and force application rod first through push rod one end through hole, then assembles with nut.
An extracting tool for rearmounted exciter rotor in electrical micro-machine, is made up of dismounting dish, spacer shell, push rod, set bolt, force combination etc.Set bolt through 4 through holes of dismounting dish and exciter rotor with exciter hold-down nut clamping, fix, force combination drives push rod to rotate, exert a force through spacer shell countershaft, because rotating shaft axially can not be moved, so push rod position is not moved, finally dismounting dish is under the effect of the screw thread pair coordinated with push rod, realizes mobile, reaches the object of exciter rotor dismounting.
Its operation principle: set bolt is by the through hole around dismounting dish, again by the ventilation hole of exciter rotor, fastening with the exciter hold-down nut be embedded on exciter rotor, dismounting dish, set bolt, exciter rotor, exciter hold-down nut are connected as a whole.Push rod is driven to rotate together by rotating force combination, the rotating shaft of generator, spacer shell, push rod are not axially having relative motion, due to the effect of push rod and dismounting dish screw thread pair, dismounting is coiled and is moved to away from electrical micro-machine direction relative to push rod, by the transmission effect of set bolt, drive exciter rotor to move to away from electrical micro-machine direction together, depart from alternator shaft gradually, finally reach the object of dismounting exciter rotor.
The utility model has the advantage of: kit makes exciter rotor uniform force, unloading process can not damage the parts such as rotating shaft, ensures dismounting quality; Simple to operate, easy to use, an operative employee just can complete and all dismantle operation, and promote operating efficiency, execute-in-place is safe and reliable; And kit is with low cost, processing is simple, and raw material are all that market extensively adopts.

Embodiment
as shown in figures 1-8,an extracting tool for rearmounted exciter rotor in electrical micro-machine, comprises dismounting dish 1, spacer shell 2, set bolt 3, push rod 4 and force combination 5.First electrical micro-machine exciter rotor 6 back-up ring is removed; The through hole of set bolt 3 by dismounting dish 1 and the ventilation hole of exciter rotor 6, screw with exciter hold-down nut 7; In force combination 5, force application rod 11 is through the through hole of push rod 4, installs, fastening with nut 12; Push rod 4 is connected by the effect of screw thread pair with lining 10 in dismounting dish 1, and through lining 10, is placed on by spacer shell 2 between dismounting dish 1 and electrical micro-machine rotating shaft 8, is placed into by micro-motor rotor lead wire in the accommodation hole of spacer shell 2 left end, avoid being damaged.Set bolt 3 is by the through hole around dismounting dish 1, again by the ventilation hole of exciter rotor 6, fastening with the exciter hold-down nut 7 be embedded on exciter rotor 6, make dismounting dish 1, set bolt 3, exciter rotor 6, exciter hold-down nut 7 connect as a whole.Push rod 4 is driven to rotate together by rotating force combination 5, the rotating shaft 8 of electrical micro-machine, spacer shell 2, push rod 4 are not axially having relative motion, because push rod 4 and dismounting dish 1 are in the effect of screw thread pair, dismounting dish 1 moves to away from electrical micro-machine direction relative to push rod 4, by the transmission effect of set bolt 3, drive exciter rotor 6 to move to away from electrical micro-machine direction together, depart from electrical micro-machine rotating shaft 8 gradually, finally reach the object of dismounting exciter rotor 6.
Wherein dismounting dish is containing disk and lining two groups of component units, and lining is welded on disc centre hole; Force combination is assembled by force application rod and nut.The parts of extracting tool form by cold-rolled steel Q235 or other steel class materials processing, operative employee applies certain active force to force combination and forms moment, force is combined and drives push rod to rotate together, because push rod is not axially moving, dismounting dish is by the screw thread pair effect with push rod, relative motion is formed with electrical micro-machine, move to away from electrical micro-machine direction gradually, and exciter rotor, exciter hold-down nut, fixed lever and dismounting dish are mounted with, exciter rotor is disassembled dribbling and moves and move toward away from the direction of electrical micro-machine together, finally be separated with electrical micro-machine, the object of dismounting.Kit makes exciter uniform force, and unloading process can not damage the parts such as rotating shaft, ensures dismounting quality; Simple to operate, easy to use, an operative employee just can complete and all dismantle operation, and promote operating efficiency, execute-in-place is safe and reliable; And kit is with low cost, processing is simple, and raw material are all that market extensively adopts.
