Abstract
The utility model discloses a piston tail pushes away structure, include: piston shaft, piston tail push away, first shock attenuation gasket, double seal circle, wear ring, second shock attenuation gasket, the rear end of piston shaft is connected with the piston tail and pushes away, the piston tail pushes away the piston shaft of front side and installs first shock attenuation gasket, the surface that the piston tail pushed away is equipped with first mounting groove and second mounting groove, install double seal circle in the first mounting groove. The utility model relates to a piston tail pushes away structure's advantage is: the damping gaskets are positioned on two sides of the tail push piston, so that the whole device has the functions of buffering and pressure reduction, the internal structure is protected, and the whole device is more durable; the inside groove structure that uses of dual sealing washer, push away piston in close combination with the tail, reached seamless butt joint, can prevent that outside foreign matter from getting into and damaging the piston tail and push away, the leakproofness is good.
Description
Technical Field
The utility model relates to an accurate mechanical technical field especially relates to a piston tail pushes away structure.
Background
Currently, the pneumatic motor module is a device for converting the pressure of compressed air into rotational mechanical energy, which acts as an electric motor or a hydraulic motor, and converts the compressed gas energy into mechanical energy in pneumatic transmission to generate rotational motion. The piston type motor module mainly comprises a connecting rod, a piston, a cylinder, a machine body and the like, compressed air enters the cylinder to expand to do work, and the connecting rod pushes a crankshaft to rotate. In the process of piston motion, the piston tail of the existing pneumatic motor module is pushed in the motion process, so that abrasion easily occurs, the sealing performance is poor, the service life is short, the device needs to be replaced in time, and the stability of the device is low.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: the piston tail pushing structure is good in wear resistance, shock absorption, slow pressing and good in sealing performance.
In order to solve the technical problem, the utility model discloses a technical scheme is: a piston tail pushing structure comprising: piston shaft, piston tail push away, first shock attenuation gasket, double seal, wear ring, second shock attenuation gasket, the rear end of piston shaft is connected with the piston tail and pushes away, the piston tail pushes away the piston shaft of front side and installs first shock attenuation gasket, the surface that the piston tail pushed away is equipped with first mounting groove and second mounting groove, install double seal in the first mounting groove, install wear ring in the second mounting groove, the rear side that the piston tail pushed away is equipped with the mounting groove, install the second shock attenuation gasket in the mounting groove.
Preferably, the wear-resistant ring is made of stainless steel.
Preferably, the front end of the piston shaft is provided with a through hole.
Preferably, the double sealing ring is provided with a groove.
The utility model relates to a piston tail pushes away structure's advantage is: the structure is compact, and the damping gaskets are positioned on two sides of the tail push piston, so that the whole device has the functions of buffering and pressure reduction, the internal structure is protected, and the whole device is more durable; the wear-resisting ring has the similar effect as the shock-absorbing gasket and also has the compression-resisting effect, and the used material is stainless steel, so that the wear-resisting ring has good wear resistance and compression resistance; the double sealing ring is internally provided with a groove structure, and is tightly combined with the tail push piston, so that seamless butt joint is achieved, the tail push of the piston can be prevented from being damaged due to the entering of external foreign matters, the sealing performance is good, and the service life is prolonged; the through hole that the piston shaft head portion left is connected with the track aperture of inside, makes whole more firm.

As shown in fig. 1-2, a piston tail-pushing structure includes: piston shaft 1, piston tail push away 2, first shock attenuation gasket 3, double seal 4, wear ring 5, second shock attenuation gasket 6, the rear end of piston shaft 1 is connected with the piston tail and pushes away 2, the piston tail pushes away and installs first shock attenuation gasket 3 on the piston shaft 1 of 2 front sides, the piston tail pushes away 2 the surface and is equipped with first mounting groove 21 and second mounting groove 22, install double seal 4 in the first mounting groove 21, install wear ring 5 in the second mounting groove 22, the piston tail pushes away 2 the rear side and is equipped with mounting groove 23, install second shock attenuation gasket 6 in the mounting groove 23.
Further, the wear-resistant ring 5 is made of stainless steel.
Further, the front end of the piston shaft 1 is provided with a through hole 11.
Further, a groove 41 is formed on the double seal ring 4.
The utility model relates to a piston tail pushes away structure, compact structure, first damping shim 3 and second damping shim 6 are located the both sides that the tail pushed away piston 2, play the effect of buffering, decompression to whole device, are favorable to protecting the inner structure, make the whole of this device more durable; the wear-resisting ring 5 has the similar function as the damping gasket and also has the compression-resisting effect, and the used material is stainless steel, so that the wear-resisting ring has good wear resistance and compression resistance; the groove 41 is arranged in the double sealing ring 4 and is tightly combined with the tail push piston 2, so that seamless butt joint is achieved, external foreign matters can be prevented from entering to damage the piston tail push 2, the sealing performance is good, and the service life is prolonged; the through hole 11 left on the head of the piston shaft 1 is connected with the small hole (not marked in the figure) of the inner track, so that the whole body is more stable.
