Abstract
The utility model discloses a pneumatic actuator which has better generality and comprises a box body, wherein a shifting fork is arranged in the box body; the shifting fork comprises a chute part; only one air cylinder is connected with the box body; and a piston rod of the air cylinder is connected with a shifting fork driving mechanism which is slidingly matched with the chute part. The shifting fork driving mechanism can comprise a guide block, wherein the guide block is connected with the piston rod of the air cylinder; a guide hole is arranged on the guide block; the guide block is slidingly matched with a guide rod arranged in the box body; the axial direction of the guide rod is parallel to the axial direction of the piston rod; the guide block is also connected with a pin shaft; and the pin shaft is provided with a sliding block that is slidingly matched with the chute part of the shifting fork. As only one air cylinder is arranged, the length of the pneumatic actuator can be shortened obviously, therefore, the pneumatic actuator has lower requirement on the installation space, so that the generality is better; in addition, with the adoption of the shifting fork driving mechanism, the production cost can be lowered.
Description
Technical field
The utility model relates to a kind of pneumatic actuator that control valve opens and closes that is used for.
Background technique
At present; The pneumatic actuator that is used for the control valve switching generally comprises a casing, and the both sides of casing respectively are connected with a cylinder, two shared piston rods of cylinder; Be connected with bearing pin on the piston rod; Above-mentioned bearing pin is slidingly matched with the slide groove portion that is arranged on the shift fork in the casing, and, the two ends of above-mentioned bearing pin respectively with the inwall of casing on the guiding groove that is provided be slidingly matched.During use, through the straight line motion drive bearing pin straight line motion of piston rod, the straight line motion of bearing pin drives shift fork and is rotated the switching of the rotation may command valve of shift fork.Not enough below said structure exists: 1, owing to use two cylinders, make that the overall dimensions of pneumatic actuator is longer, the installing space that needs is comparatively long and narrow, and versatility is relatively poor; 2, be not easy to maintenance; 3, use two cylinders, make that the cost of pneumatic actuator is higher; 4, on the inwall of casing, guiding groove is set, is not easy to processing and maintenance, cost is higher.
The model utility content
The technical problem that the utility model solves provides a kind of versatility pneumatic actuator preferably.
The utility model solves the technological scheme that its technical problem adopted: pneumatic actuator; Comprise casing; Box house is provided with shift fork; Said shift fork comprises slide groove portion, only is connected with a cylinder on the said casing, is connected with the shift fork driving mechanism that is slidingly matched with said slide groove portion on the piston rod of said cylinder.
Further be: said shift fork driving mechanism comprises guide pad, and said guide pad links to each other with the piston rod of said cylinder; Said guide pad is provided with pilot hole, and said guide pad is slidingly matched through pilot hole and the guide rod that is arranged in the casing, the parallel to an axis of the axial and said piston rod of said guide rod; Also be connected with bearing pin on the said guide pad, said bearing pin is provided with the slide block that the slide groove portion with shift fork is slidingly matched.
Further be: be provided with sliding bearing in the pilot hole of said guide pad, said guide pad is slidingly matched through said sliding bearing and said guide rod.
The beneficial effect of the utility model is: owing to only be provided with a cylinder, can significantly shorten the length of pneumatic actuator, make pneumatic actuator lower to the requirement of installing space, so versatility be better.

Fig. 2 is the enlarged view of a-quadrant among Fig. 1;
The schematic representation that Fig. 3 is slidingly matched through slide block and slide groove portion for the bearing pin on the guide pad.
Be labeled as among the figure: 1-piston rod, 2-bearing pin, 3-slide block, 4-slide groove portion, 5-guide rod, 6-pilot hole, 7-guide pad, 8-casing, 9-cylinder, 10-shift fork.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1, the pneumatic actuator of the utility model comprises casing 8; Casing 8 set inside have shift fork 10; Said shift fork 10 comprises slide groove portion 4, only is connected with a cylinder 9 on the said casing 8, is connected with the shift fork driving mechanism that is slidingly matched with said slide groove portion 4 on the piston rod 1 of said cylinder 9.Owing to only be connected with a cylinder 9 on the casing 8, make the entire length of pneumatic actuator significantly reduce, lower to the requirement of installing space, versatility is better.
The mode of execution of above-mentioned shift fork driving mechanism has multiple; For example available shift fork driving mechanism of the prior art just connects bearing pin on piston rod, the slide groove portion of bearing pin and shift fork is slidingly matched; The two ends of bearing pin respectively with the inwall of casing on the guiding groove that is provided be slidingly matched; But said structure is not easy to processing and maintenance owing to need on the inwall of casing, guiding groove be set, and cost of production is higher.In order to reduce cost, be convenient to processing and maintenance, to shown in Figure 3, said shift fork driving mechanism comprises guide pad 7 like Fig. 1, said guide pad 7 links to each other with the piston rod 1 of said cylinder 9; Said guide pad 7 is provided with pilot hole 6, and said guide pad 7 is slidingly matched through pilot hole 6 and the guide rod 5 that is arranged in the casing 8, the parallel to an axis of the axial and said piston rod 1 of said guide rod 5; Also be connected with bearing pin 2 on the said guide pad 7, said bearing pin 2 is provided with the slide block 3 that the slide groove portion 4 with shift fork 10 is slidingly matched.Adopt said structure; The straight line motion of piston rod 1 can drive guide pad 7 to carry out straight line and moves; Guide pad 7 is led and is driven bearing pin 2 by guide rod 5 in moving process and moves, and the moving of bearing pin 2 can drive slide block 3 shift forks 10 and rotate the switching of the rotation actuatable valve door of shift fork 10.
In order to make guide pad 7 along guide rod 5 smooth and easy slips, be provided with sliding bearing in the pilot hole 6 of said guide pad 7, said guide pad 7 is slidingly matched through said sliding bearing and said guide rod 5.
