Abstract

Novel buffering cylinder device. The invention particularly relates to the technical field of a buffer cylinder. The piston is provided with a middle hole, the piston rod penetrates through the middle hole of the piston and can axially move in the piston, the upper end of the piston rod penetrates through the end face of the cylinder body to be fixedly connected with the cylinder body, and the lower end of the piston rod is connected with the impact piece. The piston rod penetrates through the piston to be connected with the cylinder, so that the cylinder moves relative to the piston, when the piston contacts the bearing piece, the impact piece drives the cylinder to move downwards, compressed gas in the cylinder is discharged through the silencing throttle valve, the speed of relative movement is reduced, and buffering is realized; the design combined with the silencing cavity ensures that the noise of the cylinder is lower during the buffering work. The invention is suitable for buffering when a large-load impact piece impacts a bearing piece at a high speed, and is particularly suitable for cold regions.

Description

Cushion cylinder device
Technical field
The present invention relates to a kind of cylinder, relate in particular to a kind of cushion cylinder technical field.
Background technique
The object of high-speed mobile when arriving target stroke, can produce bump with junction plane.In the past, people were provided with elastic material at the surface of contact of two articles, as rubber, sponge etc., protected object, prevented that such benefit is that cost is low because of bump damages object, and shortcoming is that the life-span is short, poor reliability.On the object of some big quality, high-speed mobile, such way to play for time is obviously inapplicable; So, people adopt hydraulic pressure, pressure buffer device to realize buffering, adopting the device that has pooling feature to realize buffering near the position of target, this device can slow down near the target location time until stopping reposefully, but the hydraulic pressure installation maintenance period is short, and user cost is higher relatively, at cold area, hydraulic oil can freeze, and reliability is low; The noise of pressure buffer device is big, often is arranged on the load bottom, and himself will carry the impact of impulse member, damages easily.
Summary of the invention
The present invention is directed to above defective, a kind of direct impact that can avoid impulse member is provided, and have the cushion cylinder device of silencing function.
The object of the present invention is achieved like this: it vertically is provided with and connects load-bearing member and impulse member, it is made up of cylinder body, piston, piston rod, the cylinder body upper-end surface is provided with outlet valve, the corresponding load-bearing member in the lower end surface of piston, piston is established mesopore, and piston rod passes the piston mesopore, can in piston, axially move, the upper end of piston rod passes the cylinder body end face fixedlys connected with cylinder body, and the lower end of piston rod connects impulse member.
The outlet valve of described cylinder body upper-end surface is the noise reduction exhaust shutter.
The top of cylinder also is provided with silencing cavity, piston rod passes silencing cavity, at the overhead cover of piston rod one spacer, spacer is consistent with the silencing cavity height, the upper-end surface of spacer and silencing cavity is provided with cover plate, and piston rod continues across cover plate, and fixedlys connected with cover plate, be provided with quieter material in the silencing cavity, silencing cavity is established relief opening.
Described quieter material is arranged on one to have in the container of mesh, and this container is arranged on silencing cavity top, below the cover plate, is connected with silencing cavity chamber wall.
The present invention passes piston with piston rod and is connected with cylinder, cylinder is taken exercises, when piston touches load-bearing member with respect to piston, impulse member drives cylinder and moves downward, the gas of compression is discharged by a noise reduction throttle valve in the cylinder, slows down the speed of relative movement, realizes buffering; Make that in conjunction with the design of silencing cavity the noise of cylinder when the buffering work is lower.Buffering when the present invention is applicable to big load impact spare high speed impact load-bearing member is particularly useful for cold area.

Embodiment
Load-bearing member 10 is established mesopore, but impulse member 11 is located in this mesopore and unrestricted motion, is provided with rubber buffer ring 1 in the upper-end surface of load-bearing member 10, the upper-end surface of corresponding load-bearing member 10 is provided with piston 2, and piston rod 3 is located in the mesopore of piston 2, radial seal, but unrestricted motion; Silencing cavity is established on the top of cylinder body 4, pass cylinder body 4 and silencing cavity at piston rod 3, the empty cover of the part of piston rod 3 in silencing cavity one spacer 6, spacer 6 is consistent with the silencing cavity height, the upper-end surface of spacer 6 and silencing cavity is provided with cover plate 9, piston rod 3 continues across cover plate 9, and fixedlys connected with cover plate 9, is provided with quieter material 8 in the silencing cavity, quieter material 8 is arranged on one to have in the container 7 of mesh, this container 7 is arranged on silencing cavity top, below the cover plate 9, is connected with silencing cavity chamber wall; Silencing cavity is established relief opening; The lower end of piston rod 3 connects impulse member 11.
Quieter material 8 can be selected noise reduction sponge, noise reduction felt, micropore noise reduction vacuolar membrane etc. for use.
Working principle of the present invention is: when impulse member 11 moves down, driving cylinder body 4 by piston rod 3 moves down, gas is compressed in the cylinder body 4, pressurized gas is slowly discharged by the outlet valve 5 that is provided with on the cylinder body 4, realize damping, thereby slow down the speed that moves downward and reduce impact force,, realized the two-stage buffering in conjunction with the rubber ring 1 that load-bearing member 10 upper-end surfaces are provided with.
