Description
Technical field
The utility model relates to cylinder, particularly relates to a kind of bi-directional synchronization double-acting cylinder.
Background technique
The structure of existing cylinder mostly is one-way cylinder, in a cylinder, a piston is set, piston can only move reciprocatingly to a direction, this cylinder traffic direction is single, particularly at some, needs on the mould or machine of bi-directional synchronization, is unsuitable for adopting this one-way cylinder to drive, but by synchronous tooth bar and gear transmission, but it is easy to wear that synchronous tooth bar exists, processing trouble, installs the shortcomings such as inconvenient.
Summary of the invention
The purpose of this utility model is the shortcoming existing in order to overcome prior art, provides a kind of simple in structure, use, easy for installation, and bi-directional synchronization operation, action is accurate, the bi-directional synchronization double-acting cylinder operating steadily.
The technological scheme of the utility model bi-directional synchronization double-acting cylinder is: it is characterized in that comprising left cylinder block and right cylinder block, in left cylinder block, left end cap is installed, on left end cap, have left inlet hole, in right cylinder block, right end cap is installed, on right end cap, have right inlet hole, end cap in installing between left and right cylinder block, middle-end covers and has middle inlet hole, in left cylinder block, be provided with left piston, in right cylinder block, be provided with right piston, piston packing is respectively set on left and right piston, and piston packing contacts with left and right cylinder block inwall.
The utility model discloses a kind of bi-directional synchronization double-acting cylinder, when will the left and right piston of cylinder is protruding, middle inlet hole at middle end cap passes into air pressure, air pressure enters in left and right cylinder block by middle inlet hole, left piston is pushed to the left simultaneously, right piston pushes to the right, makes the piston rod of piston protruding; In the time the left and right piston of cylinder will being retracted to centre, in the left inlet hole of left end cap and the right inlet hole of right end cap, pass into air pressure simultaneously, the air pressure by both sides promotes left and right piston to centre, make in the left and right cylinder block of left and right piston-retraction.This programme bi-directional synchronization double-acting cylinder, is divided into symmetrical two joints by cylinder block, and three of left, center, right inlet hole is set in left and right cylinder block, simple in structure, left and right piston stretches out to both sides, retract action is synchronously consistent, and action accurately, operates steadily.
The utility model bi-directional synchronization double-acting cylinder, arranges left wear ring on described left piston, right wear ring is set on right piston, and left wear ring contacts with left cylinder block inwall, and right wear ring and right cylinder block inwall contact.There is left and right wear ring, improved the working life of left and right piston.Left buffer stopper is set on described left piston, right buffer stopper is set on right piston, left buffer stopper contacts with the left end inwall of left cylinder block, right buffer stopper contacts with the right-hand member inwall of right cylinder block, left cushion seal circle is installed in left end cap, right cushion seal circle is installed in right end cap, and left and right cushion seal circle contacts with left and right buffer stopper.Had left and right buffer stopper, avoided left and right piston excessive velocities when outwards promoting to bump with left and right cylinder block inwall, guaranteed working life, left and right cushion seal circle contacts with left and right buffer stopper, raising sealing.
Accompanying drawing explanation
