Description
Technical field
The present invention relates to a kind of pneumatic control components.Be particularly related to a kind of buffer intensity with the external buffer of the cylinder of cushion stroke even variation.
Background technique
Existing bounce cylinder by closing the bigger main gas port of ventilation section area, forces pressurized air to flow out from the less buffering mouth of ventilation section area when cylinder piston moves to the cylinder end, reaches the buffering purpose thereby make piston slow down motion speed.Because main gas port and cushion gas mouth section area difference are bigger, when gas port switched, buffer intensity changed greatly, moved unsmoothly, easily produced impact shock.Simultaneously, the buffering of existing bounce cylinder only just can play buffer function when cylinder piston moves near two ends, and cylinder piston does not possess pooling feature not near the end time.In addition, the impact that existing buffer will bear the certain energy of moving element makes it reduce motion speed, thereby the cushioning effect of buffer is strong and weak relevant with its physical dimension usually.That is to say that its physical dimension also must be bigger if require the buffer capacity of buffer bigger.
Summary of the invention
Easily produce the problem of impact shock in order to solve cylinder piston can not move in any position buffering, when buffering, the utility model provide a kind of when making cylinder piston can both cushion and be transformed to kicking motion in any position buffer intensity change evenly, the external buffer of cylinder of transitions smooth.
The external buffer of the utility model cylinder comprises the buffer cylinder body, is installed in middle cover in the buffer cylinder body, is installed in valve rod and spring in the middle cover; Near the one end two air pipe interfaces are arranged on the buffer cylinder body, one of them air pipe interface communicates with cylinder exhaust port, with air pipe interface opposite position place long and narrow hole is arranged on the middle cover, spring is arranged in the end of middle cover near long and narrow hole, valve rod one end is sleeved on that the other end is exposed to outside the middle cover in the middle cover, and can slide in middle cover, simultaneously, valve rod one end and spring join, and it is corresponding with the cylinder piston rod position to be exposed to the outer the other end of middle cover.The relative installation of buffer and cylinder is provided with according to the requirement of cylinder buffering position.
The air-flow of discharging from cylinder exhaust port flows into the air pipe interface that communicates with cylinder exhaust port, and the long and narrow hole of the middle cover of flowing through flows out from another air pipe interface.When valve rod be subjected to cylinder piston rod bump, when the buffer cylinder interior is slided, the spring stress compression, long and narrow hole is gradually by the valve rod shutoff, the distance that valve rod slides in middle cover is long more, long and narrow hole is big more by the area of shutoff, but the area that air feed stream flows through is just more little, therefore, the inblock cylinder atmidometer increases gradually, and the motion speed of cylinder piston also reduces gradually.
When the motion of valve rod direction was left by cylinder piston rod court, valve rod slided in middle cover under the spring force effect of pressure spring and resets, and air-flow can flow through in long and narrow hole without barrier.
In sum, the beneficial effects of the utility model are as follows:
Long and narrow hole is arranged on the middle cover, and the breathing area by the slip change long and narrow hole of valve rod in middle cover smoothly reduces the cylinder piston movement velocity gradually, thereby makes cylinder buffering level and smooth.
Because the relative installation of buffer and cylinder can be provided with according to the requirement of cylinder buffering position, thereby cylinder can be arranged on arbitrary position acquisition buffering as required.
Because the buffer that the utility model provides adopts the mode of control cylinder exhaust velocity to make the motion of cylinder obtain buffering, buffer itself needn't bear greater impact, thereby for needing the bigger occasion of buffer intensity, the physical dimension that the physical dimension of buffer can have buffer now significantly reduces, thereby its user cost is also relatively low.
