Brief description of the drawings
Fig. 1 is the structural representation of one embodiment of the present of invention；
Fig. 2 is the cooperation schematic diagram of shifting axle and cored screw in Fig. 1.
Specific embodiment
The breaker embodiment of auxiliary switching-in instrument is as shown in Figure 1 and 2：Including splined spanner 1 and tool rack, spline is pulled
One end of hand is provided with the splined hole being sheathed on for rotation stop on the spline spindle 10 of respective circuit breakers, and the other end of splined spanner sets
There is the length bearing of trend connection elongated hole 15 consistent with splined spanner length bearing of trend.Tool rack include plate after along the vertical direction
The connecting plate 2 being connected for the housing with breaker for extending, is provided with drive mechanism on connecting plate, drive mechanism has can
Export above-below direction linearly operating and move the linearly operating output end of locking in place, drive mechanism includes being fixedly arranged on connecting plate
The vertically extending female swivel nut 6 of tool of axis, linearly operating output end includes that spinning is hollow in swivel nut
Screw rod 5 and the shifting axle 4 being arranged in the endoporus of cored screw, the upper end of shifting axle be provided with it is outer turn edge 12, cored screw 5
Endoporus is shoulder hole, and shoulder hole has big hole section and aperture section setting up and down, turn edge outward 12 be located at big hole section in, shifting axle 4
It is threaded onto in aperture section, turns edge thrust bearing 3 is provided between 12 and the step surface 11 of shoulder hole outward, is turned edge in outward in big hole section
Upside be provided with spanner perforation 13, spanner perforation constitute for moment of torsion input moment of torsion input structure.The lower end of shifting axle
Bearing pin 9 is provided with by U-shaped part 7, the axis of bearing pin and the diameter parallel of splined hole, U-shaped part include bottom wall and spaced
Two side, bottom wall is fixedly welded on shifting axle, and bearing pin is arranged in the pin-and-hole 14 of the two side of U-shaped part, while bearing pin wears
Slided so as to drive spline to pull in elongated hole is connected when in connecting elongated hole 15 with linearly operating output end output linearly operating
Hand 1 rotates around the axis of splined hole, and the both sides of U-shaped part are provided with block card 8 on bearing pin, and block card can prevent bearing pin by U-shaped part
Upper abjection.
Locking is referred to after shifting axle moves to a certain position in place for motion in the present invention, when the power of drive mechanism
During disappearance, shifting axle is just locked in the position and will not move up and down, in the present embodiment shifting axle be by swivel nut with it is hollow
Locking in place is realized in threaded connection between screw rod.This breaker is with the use process of auxiliary switching-in instrument, need by
When breaker is adjusted to closing position by open position, because breaker does not install switching-in spring also, therefore can only be by auxiliary
Instrument realizes the adjustment of breaker, and connecting plate is fixed on the housing of breaker by bolt, by the spline on splined spanner
Hole rotation stop is set on the spline spindle of breaker, and a force spanner, Ran Houzhuan are installed in the spanner perforation of cored screw
Dynamic force spanner, cored screw is moved upward in swivel nut, and the step surface of shoulder hole drives shifting axle upward by thrust bearing
Mobile, simultaneously because the effect of thrust bearing, shifting axle only axially moves without rotation, and shifting axle drives bearing pin to transport upward
Dynamic, bearing pin is slided in elongated hole is connected so as to drive splined spanner to be rotated around the axis of splined hole, and spline spindle is with splined spanner
Rotate together, when breaker reaches closing position, stop to cored screw input torque, under the self-locking of screw thread, hollow spiral shell
Bar and shifting axle are locked out, and breaker is also located in closing position, to carry out the installation of switching-in spring.Two point is drawn in Fig. 1
Line represents the present position of breaker splined spanner in open position, and solid line represents breaker splined spanner in closing position
Present position.
In other embodiments of the invention：U-shaped part can not also set, and now bearing pin can be directly arranged at shifting axle
On；Connecting plate be can also be without being directly fixed on the housing of breaker, such as breaker is fixed on assembly platform, by even
Fishplate bar also is secured on assembly platform, as long as ensureing that connecting plate is relatively fixed with the housing of breaker；Connecting plate can be with
It is the other structures such as framework；Spanner perforation other moment of torsion input structures can also be replaced by outer square shaft, interior square hole etc.；Drive mechanism
A screw-nut mechanism is can also be, screw can export the linearly operating on above-below direction as moment of torsion input component, leading screw,
Bearing pin is arranged on leading screw, and now the screw thread between leading screw and screw coordinates can realize guide screw movement locking in place；Certainly,
Drive mechanism can also be that cylinder, hydraulic cylinder etc. are this kind of and can be moved to linearly operating output end and linearly operating output end
Position lockable mechanism, cylinder, the piston rod of hydraulic cylinder are linearly operating output end, after piston rod stretches out, gas in cylinder and
Liquid in hydraulic cylinder can make piston rod movement locking in place.
