Abstract
The invention discloses an air cylinder type actuating mechanism. The air cylinder type actuating mechanism comprises an air cylinder, a push rod, a support disposed under the air cylinder and a piston which is provided with a hole and arranged inside the air cylinder and on the upper portion of the support. An adjusting screw extending to inside of the air cylinder is disposed at the top of the air cylinder; the lower portion of the adjusting screw is connected with a spring shield; a reset spring is connected between the spring shield and the piston; the lower portion of the air cylinder is fixedly connected with the support; the lower portion of the push rod is disposed inside the support; the upper portion of the push rod penetrates through the hole of the piston to extend into the air cylinder; a push rod isolating sleeve is disposed on the outer side of the upper portion of the push rod; one end of the push rod isolating sleeve is connected with a locking nut disposed at the top end of the upper portion of the push rod, and the other end of the push rod isolating sleeve makes contact with the piston; and a push rod corrugated pipe or a spring is further disposed on the outer side of the lower portion of the push rod. According to the air cylinder type actuating mechanism provided by the invention, the travel speed of the actuating mechanism can be adjusted, and the problem of speed caused during operation of the air cylinder type actuating mechanism is solved.
Description
Technical field
The present invention relates to a kind of actuator, be specifically related to a kind of air-cylinder type actuator.
Background technology
Bleed pressure that air-cylinder type actuator can be born is high, thrust is big, travel speed is fast and sturdy and durable. Adapted double-purpose valve door holder, the upper and lower of cylinder accepts pure compression air simultaneously, and discord corrosive atmosphere environment carries out gas exchange, never corrodes, long service life. Pressing double-acting cylinder actuator action during normal operation, during air failure, spring can make spool safety reset, makes valve closing or opens.
Cylinder actuating mechanism exist in running acceleration, at the uniform velocity, the stage such as deceleration, therefore the travel speed of actuator is controlled to seem particularly significant in practice.
Summary of the invention
The present invention provides a kind of air-cylinder type actuator, and this actuator can increase the travel speed adjusting actuator, solves the speed issue that cylinder actuating mechanism runs in running.
The purpose of the present invention reaches by the following technical programs:
A kind of air-cylinder type actuator, including cylinder, push rod, it is arranged on the support below cylinder and is arranged on the piston having hole above cylinder interior support, cylinder head is provided with the adjustment screw extending to cylinder interior, regulate screw and be connected below spring shield, back-moving spring it is connected between spring shield and piston, cylinder bottom is connected with support by cylinder snap ring, push rod bottom is arranged on internal stent, push rod top extends to cylinder interior through the hole of piston, push rod upper outside is provided with push rod separation sleeve, the locking nut that push rod separation sleeve one end is arranged with push rod upper end is connected, one end and piston contact, push rod lower outside is additionally provided with push rod corrugated tube or spring. when the speed needing actuator in running, gas can be passed in cylinder or reduce gas, change the elastic force received of back-moving spring thus changing the thrust that push rod is subject to, and then change the deformation quantity of push rod corrugated tube or spring, regulate required travel speed. back-moving spring is when air failure, and the parts as safety reset use.
Described push rod is connected with pushrod clip, pushrod clip and the sliding bar being arranged on the vertical direction of internal stent side and connects, and is provided with stroke scale relative to the side of slide bar in described support. The stroke of the actuator under corresponding pressure can be accurately known in the setting of pushrod clip and stroke scale, thus may know that travel speed, knows the performance of actuator.
Described push rod and support contact portion are provided with on push rod lining, and on push rod, lining is connected with under push rod lining, and push rod is additionally provided with support push rod O between lining under lining and push rod. The setting of the upper and lower lining of push rod can make push rod and support close contact prevent push rod landing.
Described piston is provided with piston O.
Described frame upper is provided with support O.
The setting of a series of O by tight for actuator inner sealing, can improve the performance of whole actuator.
The present invention compared with prior art, is had the following advantages that and beneficial effect:
The present invention is provided with push rod corrugated tube or spring in the bottom of push rod, can according to speed required in actual motion, adjust the gas flow in cylinder and then change the deformation quantity of push rod corrugated tube or spring, thus reaching to change the purpose of the opening speed of actuator 3.
Accompanying drawing explanation
Figure l is the structural representation of the present invention.
Detailed description of the invention
Embodiment
As shown in Figure l, a kind of air-cylinder type actuator, including cylinder l, push rod 6, it is arranged on the support 2 below cylinder l and is arranged on the piston 8 having hole above cylinder l internal stent 2, cylinder l top is provided with the adjustment screw 3 extended within cylinder l, regulate screw 3 and be connected below spring shield 4, back-moving spring 5 it is connected between spring shield 4 and piston 8, cylinder l bottom is connected with support 2 by cylinder snap ring 11, it is internal that push rod 6 bottom is arranged on support 2, push rod l top extends to inside cylinder l through the hole of piston 8, push rod 6 upper outside is provided with push rod separation sleeve 9, the locking nut that push rod separation sleeve 9-end is arranged with push rod upper end is connected, one end and piston contact, push rod 6 lower outside is additionally provided with push rod corrugated tube 7 or spring.
Cylinder l top is provided with air inlet, and gas enters inside cylinder l by this air inlet, promotes piston 8 to move and also changes the elastic deformation of back-moving spring 5, thus promoting pushrod movement, band movable valve plug is turned on or off.
Back-moving spring 5 is when air failure, and the parts as safety reset use. Actuator is helped to reply when flow direction valve is typically designed to when flatus.
Needing to accelerate the travel speed of actuator, then need to change the air content in cylinder, the elastic deformation of the back-moving spring in intensifying cylinder, thus strengthening the elastic deformation of push rod corrugated tube 7 or spring.
If desired the travel speed of actuator is slowed down, then need to reduce the elastic deformation of the back-moving spring in cylinder, thus the elastic deformation reducing push rod corrugated tube or spring achieves the goal.
