Abstract
The utility model discloses a shifting fork type pneumatic actuator which has simple assembly, convenience for repair and good universality. The actuator comprises a box body, a torque transferring mechanism and a pin shaft, wherein the torque transferring mechanism is arranged in the box body; the pin shaft is connected onto a piston rod; the torque transferring mechanism consists of a shifting fork; the shifting fork comprises a sliding chute part and a shaft connecting part with a central hole; the sliding chute part is in sliding fit with the pin shaft; a torque transferring end is formed at one end of the shaft connecting part; and the torque transferring end is rotationally matched with an output hole arranged in the box body. As the torque transferring mechanism only consists of the shifting fork, a transmission shaft is saved, so that the assembly is simple, the repair is convenient, and the cost is decreased; further, when the shifting fork type pneumatic actuator is in use, a proper shaft coupling sleeve and a bracket only need to be designed, so that the shifting fork type pneumatic actuator can be connected with a valve, thereby being capable of controlling the opening and the closing of the valve; and the shifting fork type pneumatic actuator has better universality.
Description
Technical field
The utility model relates to a kind of fork type pneumatic actuator that is used for control valve.
Background technique
Present fork type pneumatic actuator generally comprises a casing, and a side of casing is connected with case lid through bolt, is connected with cylinder on the casing; The piston rod of cylinder promotes to be positioned at the shift fork rotation of box house through the bearing pin that connects on it; The shift fork of box house comprises connecting shaft portion and the slide groove portion that has center hole, and the slide groove portion of above-mentioned bearing pin and shift fork is slidingly matched, and is connected with transmission axle in the center hole of shift fork; This axle is a torque-transmitting mechanisms; This shaft extension goes out casing and links to each other with valve through coupling band, through this axle moment of torsion is passed to valve, makes valve opening or closes.There is following deficiency in the mode of this axle output torque: 1,, higher to the material and the processing request of axle in order to guarantee the working life of axle, thus cause the cost of production of final controlling element higher; 2, because of axle in whole pneumatic actuator product structure, act on very big, in case the wear extent of this axle is big or because of other damage, then need final controlling element dismantled fully and whole axle changed; 3, be unfavorable for the product assembling, it is very heavy that product seems.
The model utility content
The technical problem that the utility model solves provides the simple fork type pneumatic actuator of a kind of assembling.
The utility model solves the technological scheme that its technical problem adopted: the fork type pneumatic actuator; Comprise casing, be arranged on the torque-transmitting mechanisms of box house, and the bearing pin that connects on the piston rod; Said casing one side is provided with case lid; Said torque-transmitting mechanisms is made up of shift fork, and said shift fork comprises slide groove portion and the connecting shaft portion that has center hole, and said slide groove portion cooperates with said pin slide; One end of said connecting shaft portion forms moment of torsion transmission end, and the delivery outlet that is provided with on said moment of torsion transmission end and the casing is rotatably assorted.
Further be: the inwall of the center hole that said moment of torsion transmission end is corresponding is provided with keyway.
Further be: said case lid is provided with supported hole, and the other end and the said supported hole of said connecting shaft portion are rotatably assorted.
The beneficial effect of the utility model is: because torque-transmitting mechanisms only is made up of shift fork, saved transmission axle, made assembling simple; Easy to maintenance; Cost reduces, and when using, only needs just can the moment of torsion transmission end of shift fork be linked to each other with valve with coupling band according to the suitable support of valve design; And then the switching of may command valve, versatility is better.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As depicted in figs. 1 and 2, the fork type pneumatic actuator of the utility model comprises casing 4; Be arranged on the torque-transmitting mechanisms of casing 4 inside; And the bearing pin 3 that connects on the piston rod 5, said casing 4 one sides are provided with case lid 13, and said torque-transmitting mechanisms is made up of shift fork 7; Said shift fork 7 comprises slide groove portion 6 and the connecting shaft portion 12 that has center hole 9, and said slide groove portion 6 is slidingly matched with said bearing pin 3; One end of said connecting shaft portion 12 forms moment of torsion transmission end 10, and the delivery outlet 2 that is provided with on said moment of torsion transmission end 10 and the casing 4 is rotatably assorted.
During use, moment of torsion transmission end 10 is linked to each other the switching of the rotation may command valve through moment of torsion transmission end 10 with valve through linkage structure.For example illustrated in figures 1 and 2, the left and right sides of casing 4 is connected with cylinder 22 and the shared piston rod 5 of 21, two cylinders of cylinder respectively; Be provided with shift fork 7 in the casing; The bearing pin 3 that is connected on the slide groove portion 6 of shift fork 7 and the piston rod 5 is slidingly matched, and through the motion of piston rod 5, promotes shift fork 7 and in several angle, rotates; There is not coupling shaft in the center hole 9 of the connecting shaft portion 12 of shift fork 7; The delivery outlet 2 that is provided with on the moment of torsion transmission end 10 of connecting shaft portion 12 and the casing 4 is rotatably assorted, and moment of torsion transmission end 10 is linked to each other the switching of the rotation may command valve of moment of torsion transmission end 10 through linkage structure with valve.
For the ease of moment of torsion transmission end 10 is linked to each other with valve, the inwall of the center hole 9 of said moment of torsion transmission end 10 correspondences is provided with keyway 8.Adopt said structure,, only need just can realize being connected, therefore can improve the versatility of the fork type pneumatic actuator of the utility model according to different corresponding support of valve manufacturing and coupling bands with the effective of valve being connected with valve when supporting.
One end of above-mentioned shift fork 7 forms moment of torsion transmission end 10, and the other end can be rotatably assorted with the supporting structure that is arranged on box house, but can make box inner structure complicated like this, is not easy to assembling.For simplified structure, be convenient to assembling, said case lid 13 is provided with supported hole 1, and the other end and the said supported hole 1 of said connecting shaft portion 12 are rotatably assorted.Just shown in Figure 2, the end 11 and the supported hole 1 of the connecting shaft portion 12 of shift fork are rotatably assorted.
