Description
Technical field
The present invention relates to power equipment manufacturing technology field, the spring of particularly a kind of operation mechanism with three-position switch is filled
Put.
Background technology
The division operation of switchgear is realized using spring energy-storage operating mechanism, is the conventional hand in current switchgear
Section.Publication number CN16418115A, CN201022063Y, CN103021721A describe conventional switch spring operating mechanism.
CN16418115A discloses a kind of stored energy mechanism, including energy storage pillar, energy storage bar and energy-stored spring.Roundlet in the middle of energy storage pillar
Post and the interstitial hole of energy storage bar do gap cooperation.When it is assembled, using special tooling compressed energy-storage spring and then it need to could fix
Energy storage bar and energy storage support.CN201022063Y is disclosed energy-stored spring and fixed using pin, it is necessary to make during installation and removal
With special tooling compressed energy-storage spring, pin is then extracted, energy storage device is removed.Existing three-station spring operating mechanism
Energy-stored spring is that a pin is respectively mounted on the connecting lever of on-load switch operating shaft and ground connection operating shaft by elder generation, then will be described
The two ends of energy-stored spring are directly hung to what is fixed on two pins.Because the elasticity of the energy-stored spring is stronger, installing
It is required for carrying out precompressed energy-stored spring by special tooling during with dismounting, installs or take out pin, operation is more complicated, therefore brings
The inconvenience of installation and removal.During frock improper use simultaneously, also there is spring ejection, jeopardize the safety of operating personnel.Above-mentioned bullet
Spring mode of operation process is more, than relatively time-consuming, is limited by frock and safety, it is impossible to energy-stored spring pre-assembled.
The content of the invention
It is an object of the invention to provide a kind of three-station spring assembly, it can effectively solve the problem that energy-stored spring is dismounted
The problem of inconvenience and the potential safety hazard existed.
In order to solve the above problems, the technical scheme of this three-station spring assembly is：A kind of three-station spring
Device, includes the foreboard 1 fixed by support column 12 and back plate 6, and operating shaft 2, output shaft 3 are provided between foreboard 1 and back plate 6,
Provided with two pieces of arms 2.1 of turning right in operating shaft 2, for supporting straight pin 9, straight pin 9 is fixed by shelves card 10, in output shaft 3
Provided with two pieces of arms 3.1 of turning left, for fixing pivot pin 4, the two ends of pivot pin 4 are provided with the middle of cylinder 4.1, pivot pin 4 and are provided with through hole 4.3
With locating slot 4.2, locating slot 4.2 coordinates with the positioning boss 5.1 on spring bushing 5, and the one end of energy-stored spring 7 is installed on spring base
On 8, the side of spring base 8 is provided with semi-circular recesses 8.3, to be supported on straight pin 9, and the opposite side of spring base 8 is provided with guide rod
8.1, the one end of guide rod 8.1 is provided with screw 8.2, and the other end is fixed on spring base 8, and the other end of energy-stored spring 7 is installed on spring
On bushing 5, spring bushing 5 is provided with positioning boss 5.1 and pilot hole 5.2, and guide rod 8.1 can pass through pilot hole 5.2, screw 11 1
End is provided with stud 11.1, and one end is provided with step 11.2, and the screw 8.2 of stud 11.1 and spring base 8 coordinates, the step of screw 11
11.2 and guide rod 8.1 can pass through the through hole 4.3 on pivot pin 4.
Pivot pin 4 and straight pin 9 are used to fix energy-stored spring.Pivot pin 4 is devised, the two ends of pivot pin 4 are cylindrical pin pin structure,
The locating slot 4.2 being oriented to retaining spring bushing 5,4.2 months convexes of locating slot are provided with the middle of middle rectangular parallelepiped structure, cuboid
The gap of platform 5.1 coordinates.The operation of screw 11 for convenience, has opened through hole 4.3 in the middle of pivot pin 4, and the diameter of through hole 4.3 is more than screw
11 step 11.2 and the external diameter of guide rod 8.1, less than the external diameter of positioning boss 5.1, the external diameter of step 11.2 of screw 11 is more than
The aperture of pilot hole 5.2.Through hole 4.3 is when mounting and dismounting energy-stored spring 7, and interior hex tool twists screw 11 through through hole 4.3,
Play a part of being oriented to and position, can prevent energy-stored spring 7 from directly being come off from operating mechanism.The cylinder at the two ends of pivot pin 4
4.1 coordinate with the circular holes of two pieces of arms 3.1 of turning left on output shaft 3, and arm 3.1 of turning left is welded on output shaft 3.Cylinder（4.1）
First it is arranged on arm of turning left（3.1）Circular hole in, then by pivot pin（4）Turn left arm（3.1）It is welded on output shaft（3）On, pivot pin 4 can not
Dismounting, it is ensured that pivot pin 4 loosening, deformation will not occur because of frequent dismounting.When mounting and dismounting energy-stored spring, it is not necessary to pacify again
Dress or dismounting pivot pin 4 and straight pin 9.
Add the length of the guide rod 8.1 of spring base 8, and devise at one end screw 8.2 and with the stud of screw 11
11.1 coordinate.The length sum of guide rod 8.1 and stud 11.1 is more than the length of the nature of energy-stored spring 7.In assembling energy storage
During spring, it is not necessary to other specific purpose tool compression springs, directly compressed by the driving spring bushing 5 of 11 precession screw of screw 8.2
Energy-stored spring 7.Potential safety hazard during compression spring is eliminated, labor intensity is reduced.Therefore installed in three station operating mechanisms
Or during debugging, spring base 8, spring bushing 5, energy-stored spring 7 and screw 11 can be subjected to assembling in advance standby.Change tradition
Assembly technology can only fix the pattern of energy-stored spring by the pin on three station operating mechanisms, can shift to an earlier date or arranged side-by-side storage
The pre-assembled of energy spring, optimized production process saves assembly work.
The installation method one of three-station spring assembly：
