Description

Hydraulic cylinder device with buffering performance

Technical Field

The utility model relates to a pneumatic cylinder processing technology field, in particular to pneumatic cylinder device with shock-absorbing capacity.

Background

The hydraulic cylinder is a hydraulic actuator which converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has simple structure and reliable operation. When it is used to implement reciprocating motion, it can omit speed-reducing device, and has no transmission gap, and its motion is stable, so that it can be extensively used in various mechanical hydraulic systems. The inner cavity of the existing hydraulic cylinder is not provided with a buffer device, when the piston rod extends to the limit position, the end face of the piston rod collides with the end face of the inner cavity of the cylinder barrel, mechanical impact and noise are generated, the service life of the hydraulic cylinder is shortened, and the hydraulic cylinder is seriously influenced.

The utility model provides a pneumatic cylinder device with shock-absorbing capacity solves above-mentioned technical problem.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the current pneumatic cylinder intracavity and not set up buffer, when the piston rod stretched extreme position, the terminal surface and the cylinder inner chamber end face collision of piston rod had mechanical shock and noise production, reduced the life of pneumatic cylinder, can seriously influence this technical problem of pneumatic cylinder, provide a pneumatic cylinder device with shock-absorbing capacity and solve above-mentioned technical problem.

A hydraulic cylinder device with buffering performance is characterized in that: including cylinder head, body, cylinder bottom, preceding cylinder cap, flange, piston rod, piston, cushion collar, buffering ring and buffer block, the flange has all been welded at the both ends of body, the flange fixed connection is passed through with the one end of body to the cylinder bottom, the other end of body passes through flange and cylinder head fixed connection, the cylinder head top is equipped with preceding cylinder cap, the piston rod is located the body inner chamber to one end stretches out from preceding cylinder cap, the one end that the piston rod is located the body inner chamber is up equipped with cushion collar, buffering ring and piston from the bottom in proper order, the buffering ring is located between cushion collar and the piston to laminate with cushion collar and piston, the cylinder bottom is equipped with the buffer block mounting groove, the buffer block is installed in the buffer block mounting groove.

Furthermore, the buffer block is a porous polyurethane buffer block.

Further, the buffer sleeve is a polyethylene buffer sleeve.

Further, the buffer ring is a fluororubber sealing ring.

Compared with the prior art, the utility model has the advantages that: the utility model discloses a be equipped with buffering ring and cushion collar on the piston rod, be equipped with this design of buffer block at the bottom of the cylinder, when the piston rod stretches extreme position, the cushion collar and the buffering ring that are equipped with on the piston rod play the cushioning effect, through cushion collar and the contact of bottom of the cylinder buffer block, the piston rod can directly not carry out the contact collision with the bottom of the cylinder, reduces the impact of piston rod to the bottom of the cylinder, can not the noise, the life of extension pneumatic cylinder.
