The applicant is directed to above-mentioned existing issue, has carried out Improvement, there is provided a kind of double shift fork single-actings pneumatically perform
Device, it can make actuator export and open moment of torsion and closing torque increase, closer to the moment of torsion of rotary type valve, have and save peace
The advantages of filling space.
Technical solution is as follows used by the utility model：
A kind of double shift fork single-action pneumatic executors, including cylinder, distinguish connection end cap, shift fork in the both ends of the cylinder
The cylinder interior is arranged at, in the axle center of the shift fork by spring pin connection transmission shaft, is also opened along the periphery of the shift fork
If a pair of openings groove, abutted in the one end for stretching into cylinder in the open slot with piston by trundle, the piston it is another
End is abutted with one end of caging bolt, and the other end of the caging bolt stretches out end cap and is connected with nut thread；In the end
In lid, spring is also set up in the outer ring of the caging bolt, one end of spring is abutted with end cap inner wall, the other end of the spring
Abutted with the other end of piston.
Further as above-mentioned technical proposal is improved：
The piston is arranged symmetrically centered on the shift fork；
The pair of open slot is symmetrically opened up centered on the axle center of the shift fork；
The shift fork and transmission shaft are cylinder, are coaxially opened up on the shift fork and transmission shaft for through installation bullet
The spring catch mounting groove of spring pin；
One end that the piston is abutted with caging bolt sets stage portion；
One end that the piston is connected with shift fork stretches out to be formed for limiting opposite place's piston to fortune at cylinder axis
Dynamic extension positive stop end.
The beneficial effects of the utility model are as follows：
The utility model is simple in structure, easy to use, and two can be driven at the same time by a shift fork in the utility model
The reciprocating motion of piston, improves output torque, and shift fork is connected by trundle with piston, eliminates conventional shift fork and trundle
Between need increase slide block structure to connect the problem of, the end of piston is designed to that stage portion play the guiding role spring, this reality
Reduce most of part with new, and improve transmission efficiency, save production and assembly cost.

Embodiment
Illustrate specific embodiment of the present utility model below.
As shown in Figure 1 and Figure 2, double shift fork single-action pneumatic executors include cylinder 1, distinguish connecting pin in the both ends of cylinder 1
Lid 5, shift fork 3 are arranged inside cylinder 1, connect transmission shaft 2 by spring catch 7 in the axle center of shift fork 3, along the periphery of shift fork 3 also
A pair of openings groove 301 is opened up, a pair of openings groove 301 is symmetrically opened up centered on the axle center of shift fork 3.Pass through in open slot 301
One end that trundle 4 stretches into cylinder 1 with piston 6 abuts, and piston 6 is arranged symmetrically centered on shift fork 3, and piston 6 uses aluminium alloy
Material casting forming.The other end of piston 6 is abutted with one end of caging bolt 8, and the other end of caging bolt 8 stretches out end cap 5 simultaneously
It is connected with nut thread；In end cap 5, spring 9, one end and 5 inner wall of end cap of spring 9 are also set up in the outer ring of caging bolt 8
Abut, the other end of spring 9 is abutted with the other end of piston 6.Above-mentioned fork 3 and transmission shaft 2 are cylinder, in shift fork 3 with passing
Coaxially opened up on moving axis 2 for the spring catch mounting groove through installation spring catch 7.As shown in Fig. 2, in piston 6 and caging bolt
8 one end abutted set stage portion 602.Above-mentioned piston 6 stretches out to be formed for limiting relatively with one end that shift fork 3 is connected
Locate piston 6 to the extension positive stop end 601 of movement at 1 center of cylinder.
The specific work process of the utility model is as follows：
As shown in Figure 1, Figure 2 and Figure 3, source of the gas is ventilated, and gas is entered in cylinder 1 by the stomata at the middle part of cylinder 1, and gas pushes away
Two pistons 6 in dynamic left and right move to the left and right sides of cylinder 1 respectively, inside the left and right sides motion compresses of piston 6 both sides end cap 5
Spring 9, since each piston 6 is connected by trundle 4 with shift fork 3, at the same shift fork 3 further through spring catch 7 connect transmission shaft
2, therefore the rotation of shift fork 3 has driven the rotation of transmission shaft 2, transmission shaft 2 is rotated to be turned on and off connected valve.
Conversely, when source of the gas is died, the gas loss in cylinder 1, the spring 9 of compression produces spring force and promotes piston 6 to 1 center of cylinder
Movement, since each piston 6 is connected by trundle 4 with shift fork 3, while shift fork 3 connects transmission shaft 2 further through spring catch 7, because
The rotation of this shift fork 3 has driven the rotation of transmission shaft 2, and transmission shaft 2 is rotated to be turned on and off connected valve.
The utility model is simple in structure, easy to use, and two can be driven at the same time by a shift fork in the utility model
The reciprocating motion of piston, improves output torque, and shift fork is connected by trundle with piston, eliminates conventional shift fork and trundle
Between need increase slide block structure to connect the problem of, the end of piston is designed to that stage portion play the guiding role spring, this reality
Reduce most of part with new, and improve transmission efficiency, save production and assembly cost.
Above description is the explanation to the utility model, is not the restriction to utility model, what the utility model was limited
Scope is referring to claim, and in the case of the basic structure without prejudice to the utility model, the utility model can make any shape
The modification of formula.
