Specific embodiment
This control device has been applied to certain type aero-engine pneumatic accessories at present.
A kind of microswitch controlling device is provided, as shown in figure 1, described microswitch controlling device is moved by the machinery of valve
Make to drive, including roller 1, lever 2, piston 3, spring 4, limiting bush 5, switch base 6, microswitch 7, first
The adjustment adjustment adjustment of packing ring the 9, the 3rd of packing ring 8, second packing ring 10, bearing 11 and housing 14；
Housing 14 is sleeved on outside bearing 11；Piston 3 has each extended over push rod and piston head to two ends；The one end of lever 2 and branch
Seat 11 is rotatably coupled, and the other end of lever is with roller 1 and hook, and piston 3 is arranged in the cavity of bearing 11, living
Plug 3 push rod leant with lever, bearing is fixedly connected with switch base 6, spring supporting between piston 3 and switch base 6,
Limiting bush 5 is additionally provided between piston 3 and switch base 6；Microswitch 7 is fixed in the groove of switch base 6；The work of piston
Chock plug is located at the hollow bulb of spring, and for touching microswitch 7；Described hook is spacing in the stopper slot of bearing, is used for
Limit the stroke of piston；The roller of lever 2 cylindrical with valve Actuator Division 12 and Actuator Division 13 can be adapted.
Further, when valve Actuator Division 12 shifts up, valve Actuator Division upper end contacted with roller 1 and promote lever 2 by
Gradually to left dislocation, lever 2 reaches maximum displacement position after roller and Actuator Division cylindrical 13 contacts；The displacement of lever 2 can be pushed away simultaneously
Piston 3 is moved to the left；First adjustment packing ring 8 is arranged between switch base 6 and bearing 11, for adjusting microswitch and work
First dress distance between chock plug so that piston head just connects microswitch contact when piston 3 reaches range；Valve 12 with
The relative position of housing 14 is fixed, and the second adjustment packing ring 9 is arranged between housing 14 and bearing 11, and the second adjustment packing ring 9 is used for
The first dress distance of control lever 2 and valve 12；
After valve Actuator Division 12 moves down reset, piston and lever reset under spring force；3rd adjustment packing ring 10
Between spring 4 and piston 11, for adjusting the first dress pretightning force of spring.
The theoretical displacement stroke of microswitch contact only has 0.53mm in the annex, and switch contact is plastic material, is quick on the draw
And it is fragile fragile.Therefore the transmission levers structure of controlling switch break-make must have accurate displacement stroke to control and perfect
Anti- dieback safeguard measure, just can guarantee that the function and reliability requirement of product microswitch.
Roller is subject to the mechanical force from right-hand member to promote, and transmits the force to lever, and piston overcomes spring force under lever thrust effect
To left dislocation and microswitch contact is touched, make switch connection.Between piston and switch base be equipped with limiting bush, when piston to the left
When displacement is excessive, bushing stops with switch base right side and leaning on, and can limit the maximum displacement stroke of piston, prevents switch contact quilt
Dieback.
By choosing adjustment packing ring and combining lever arm of force result of calculation, the displacement of lever is can guarantee that for definite value and is being subject to
Lever is in vertical angle with piston rod after right-hand member mechanical force is promoted, and eliminates the angular error of relative displacement between piston rod and lever；
By choosing adjustment packing ring, the first holding position of controlling switch seat, the displacement stroke and microswitch contact position for making piston matches；
Adjustment packing ring is used for adjusting the first dress pretightning force of spring, when preventing roller and being not affected by mechanical part and promote, piston by
The situation that gases at high pressure from right chamber are promoted in advance.
When the mechanical driven that roller is subject to is cancelled, piston resets under spring force, and microswitch contact disconnects.
