Abstract
The utility model discloses a composite stiffness pneumatic cushion cylinder used for a package receiving tray, and solves the technical problem that a composite stiffness pneumatic cushion cylinder used for an existing package receiving tray is prone to causing serious damage and generating strong vibration. A cylindrical guide post (2) is fixedly arranged in the center of the bottom inside a cup-shaped cylinder body (1), and a big and up cone-shaped hole (5) is formed in the center of the bottom of a piston body (4). A ring-shaped groove (6) is arranged on the outer ring of the cone-shaped hole (5) at the bottom of the piston body (4). The ring-shaped groove (6) arranged at the bottom of the piston body (4) is connected on the side wall of the cup-shaped cylinder body (1) in a movable and sleeved mode. The cone-shaped hole (5) arranged at the bottom of the piston body (4) is connected on a cylinder head (3) in a sleeved mode. The top of the ring-shaped groove (6) is provided with an air exhausting port (7) inside the ring-shaped groove. The top of the piston body (4) is fixedly provided with a hemispherical lower base (9). The composite stiffness pneumatic cushion cylinder used for the package receiving tray is simple in structure, has good buffer effect, and improves the service life of the package receiving tray.
Description
Technical field
The present invention relates to a kind of bounce cylinder with pneumatic complex stiffness, it belongs to a kind of damping safety installations of heavy machinery.
Background technique
The upset tenesmus is poured out behind the corundum smelting stove sintering, connects bag dish carrying instantaneous kinetic energy, produces extremely strong vibrations, because existing damping device cushion stroke is not enough, it is bad serious to connect the bag adjustment debit, causes strong motion to pollute to environment simultaneously.The damping device that generally adopts at present, all be to realize buffering percussive force by deformation distance, the damping device working mechanism all is to increase along with compression distance increases rigidity, but impact force reduces along with the increase of compression distance, that is to say, the maximum timer rigidity of impact force is minimum, impact force reduces gradually, device rigidity but increases gradually, and actual working state is that minimum rigidity is born maximum bump, connects the bag dish when bearing instantaneous maximum impact, effective decrement pop-off, can think that also initial elasticity becomes rigidity, from the deformation angle analysis, reality is without cushion stroke, damping device becomes rigid body, becomes rigid impact, certainly, also can be by increasing effective compression stroke, satisfy the initial stage buffering, but certainly will strengthen device volume, occupy greater room.As take prestressing force to improve initial stage rigidity, pre compressed magnitude causes total kilometres to reduce.
Summary of the invention
The invention provides a kind of complex stiffness bounce cylinder that connects bag dish usefulness and solved the existing technical problem that used bounce cylinder causes badly damaged and generation brute force to shake easily in the bag dish that connects.
The present invention is by the above problem of following solution:
A kind of complex stiffness bounce cylinder that connects bag dish usefulness, comprise cup-shaped cylinder body, bottom center in cup-shaped cylinder body is fixedly installed cylindrical guide pillar, top at cylindrical guide pillar is fixedly installed socket cap, bottom center at piston body is provided with up big and down small round taper hole, place, outer ring at the round taper hole of the bottom of piston body is provided with toroidal cavity, the toroidal cavity of the bottom of piston body is actively socketed on the sidewall of cup-shaped cylinder body, the round taper hole of the bottom of piston body is actively socketed on the socket cap, be provided with air outlet in the toroidal cavity at the top of toroidal cavity, be fixedly installed the hemisphere lower bottom base at the top of piston body, be provided with air outlet in the round taper hole at the hemisphere lower bottom base, bottom at cup-shaped cylinder body is provided with breather check valve, is provided with seal ring between the madial wall of piston body and cup-shaped cylinder body.
Top at toroidal cavity uniformly-spaced is provided with air outlet in 4 toroidal cavities radian.
The present invention is simple in structure, has solved the existing technical problem that connects the badly damaged and powerful vibrations of bag dish, has good buffer effect, and damping significantly connects the bag dish advantage in working life with improving.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
A kind of complex stiffness bounce cylinder that connects bag dish usefulness, comprise cup-shaped cylinder body 1, bottom center in cup-shaped cylinder body 1 is fixedly installed cylindrical guide pillar 2, be fixedly installed socket cap 3 on the top of cylindrical guide pillar 2, bottom center at piston body 4 is provided with up big and down small round taper hole 5, place, outer ring at the round taper hole 5 of the bottom of piston body 4 is provided with toroidal cavity 6, the toroidal cavity 6 of the bottom of piston body 4 is actively socketed on the sidewall of cup-shaped cylinder body 1, the round taper hole 5 of the bottom of piston body 4 is actively socketed on the socket cap 3, be provided with air outlet 7 in the toroidal cavity at the top of toroidal cavity 6, be fixedly installed hemisphere lower bottom base 9 at the top of piston body 4, be provided with air outlet 11 in the round taper hole at hemisphere lower bottom base 9, be provided with breather check valve 10 in the bottom of cup-shaped cylinder body 1, between the madial wall of piston body 4 and cup-shaped cylinder body 1, be provided with seal ring 8.
Top at toroidal cavity 6 uniformly-spaced is provided with air outlet 7 in 4 toroidal cavities radian.
When piston body 4 descended, the gap was strengthened gradually, and rigidity diminishes gradually, eliminated large impact with large rigidity, realized variable rigidity property.The rigidity such as the outer hole formation of piston and cylinder body, breather check valve 10 provides the return air-flow to enter the chamber.
