Abstract
The utility model discloses an air cylinder which comprises a cylinder body, a piston, a piston rod and a sealing ring arranged between the piston and the cylinder body. The front end of the cylinder body is connected with a front cover, the back end of the cylinder body is connected with a back cover, the front cover is connected with the back cover through a screw, an air outlet hole is formed in the front cover, an air inlet hole is formed in the cylinder body, a buffer device is arranged on the back cover, the buffer device is composed of a first spring, a second spring and a pressure withstanding plate, the first spring, the second spring and the pressure withstanding plate are fixedly connected onto the back cover, and the pressure withstanding plate is connected with the back cover through the first spring and the second spring. The air cylinder enables the piston rod to be finally forced to reduce piston rate by aids of the buffer device when the rate is still high and cannot be effectively reduced after gas is discharged from an air inlet outwards before the piston rod moves to the tail end of a stroke in a homeward journey, and avoids the phenomenon that the piston is directly collided with a back wall of the cylinder body due to the over-high rate.
Description
Technical field
The utility model relates to a kind of cylinder.
Background technique
In air-driven process, cylinder piston moves to end of travel when backhaul, when speed is still very big, will clash into the cylinder body rear wall, causes the vibration of cylinder, even damages, and the stability of whole system is brought seriously influence.
The model utility content
For solving the problems of the technologies described above, the utility model provide a kind of cylinder piston at homeward journey to end of travel, in the time of after suction port discharges gas, still can't effectively reducing piston speed, be forced to the cylinder of reduction of speed at last by damping device.
For achieving the above object, the technical solution of the utility model is: a kind of cylinder, comprise cylinder body, piston, piston rod and be arranged on piston and cylinder body between seal ring, the front end of cylinder body connects protecgulum, the rear end of cylinder body connects bonnet, be connected by screw rod between protecgulum and the bonnet, air outlet hole is arranged on the protecgulum, inlet hole is arranged on the cylinder body, damping device is arranged on the bonnet, damping device is made up of first spring, second spring, the pressure-resistant plate that are fixedly connected on the bonnet, and pressure-resistant plate is connected by first spring, second spring with bonnet.
The beneficial effects of the utility model are: cylinder piston at homeward journey to end of travel, when speed still very big, in the time of after suction port discharges gas, still can't effectively reducing, by being forced to reduce piston speed at last, avoided piston because of the too high phenomenon that directly bumps against with the cylinder body rear wall of speed by damping device.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: the front end 101 of cylinder body 1, cylinder body, the rear end 102 of cylinder body, piston 2, piston rod 3, seal ring 4, protecgulum 5, bonnet 6, screw rod 7, air outlet hole 8, inlet hole 9, damping device 10, first spring 111, second spring 112, pressure-resistant plate 12.
Embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
Embodiment:
As shown in Figure 1, a kind of cylinder, comprise the seal ring 4 between cylinder body 1, piston 2, piston rod 3 and piston 2 and the cylinder body 1, the front end 101 of cylinder body 1 connects protecgulum 5, the rear end 102 of cylinder body 1 connects bonnet 6, be connected by screw rod 7 between protecgulum 5 and the bonnet 6, air outlet hole 8 is arranged on the protecgulum 5, inlet hole 9 is arranged on the cylinder body 1, damping device 10 is arranged on the bonnet 6, damping device 10 is made up of first spring 111, second spring 112, the pressure-resistant plate 12 that are fixedly connected on the bonnet 6, and pressure-resistant plate 12 is connected by first spring 111, second spring 112 with bonnet 6.
Working principle of the present utility model is: inlet hole 9 places on piston 2 homeward journeys process cylinder body 1, discharge gas by inlet hole 9, reduce cavity internal pressure, to reduce the speed of piston 2, but when piston 2 speed are still very big, continue homeward journey, at this moment, by by damping device 10, piston 2 roof pressures are on pressure-resistant plate 12, the kinetic energy of piston 2 is changed into the elastic potential energy of 12 times first springs 111 of pressure-resistant plate and second spring 112, thereby be forced to reduce piston 2 speed, avoided direct collision with the cylinder body rear wall.
