Abstract
The utility model discloses a shifting fork type pneumatic actuator which comprises a box body, a cylinder end cover, a piston and a piston rod. A guiding shaft is arranged at one end, in an inner cavity of the box body, of the piston rod, and the piston is connected at the other end, in an inner cavity of the cylinder end cover, of the piston rod. A vibration attenuation limiting shaft is arranged on the end face of the box body, and another vibration attenuation limiting shaft is arranged on the end face of the cylinder end cover. A sliding shaft is arranged in the inner cavity of the box body in a horizontal penetrating mode. A main shaft is arranged on the piston rod, and the main shaft and the piston rod are connected in a sliding mode through a main shaft sleeve. A shifting fork assembly is arranged in the main shaft and composed of shifting fork plates and sliding blocks, wherein all the shifting fork plates are mutually perpendicular. A copper sliding sleeve is arranged between the guiding shaft and the sliding shaft. The portion, in the box body, of the sliding shaft is fixedly locked through a screw. The shifting fork type pneumatic actuator has the advantages of being reasonable in design, reduced in size, long in service life, resistant to wear and corrosion, good in sealing effect, free of leakage, more convenient to maintain and greatly improved in work efficiency.
Description
Technical field
The utility model relates to a kind of pneumatic actuator, relates in particular to a kind of fork type pneumatic actuator.
Background technique
At present, known pneumatic actuator driving mechanism is divided into pinion and-rack and fork type, and the fork type pneumatic actuator is to drive shift fork by the piston rod moving linearly to rotate, thereby drives main shaft or valve rod rotation.Common pneumatic actuator structure is complicated, parts are easy to distortion in the movement process, and wear-resisting effect is bad, has so not only improved cost greatly, has secondly also reduced its working life, and then has reduced working efficiency.
The model utility content
At the deficiencies in the prior art, the utility model provides a kind of fork type pneumatic actuator.
To achieve these goals, the technical scheme in the invention for solving the technical problem is:
A kind of fork type pneumatic actuator, comprise casing, cylinder end piece, piston and piston rod, piston rod one end of cabinets cavity is provided with the axis of guide, the piston rod the other end of cylinder end piece inner chamber is connected with piston, casing and cylinder end piece end face are provided with the vibration damping position-limited shaft, crossed a slide-bar on the cabinets cavity, piston rod is provided with main shaft, be slidingly connected by collar bush between main shaft and the piston rod, be provided with pull-fork assembly in the main shaft, pull-fork assembly is made up of fork plate and slide block, and is orthogonal between each fork plate.
Be provided with a bronze medal sliding sleeve between the described axis of guide and the slide-bar.
Slide-bar on the described casing is by a screw fixing and locking.
The beneficial effects of the utility model: this model utility is reasonable in design, reduced volume, improved its working life; Wear resistant corrosion resistant, good sealing effect have been avoided leakage problem; Keep in repair more conveniently, working efficiency improves greatly.
