Abstract

The utility model relates to a light -duty two effect pneumatic cylinder, including cylinder body, piston, piston rod, end, epicoele oil pipe, cavity of resorption oil pipe and sealing washer, its characteristics are: the piston is cylindrical, is equipped with cylinder type recess at the upper surface of piston, and the bottom surface of recess is spherical, has alleviateed self weight of piston, has improved the bearing capacity of piston. Be equipped with two upper and lower recesses on the side of piston, be equipped with the sealing washer in the recess. The beneficial effects of the utility model are that: it is rational in infrastructure, can alleviate self light in weight, simple to operate, the bearing capacity is big, and the leakproofness is good, long service life.

Description

A kind of light-duty double-acting hydraulic cylinder
technical field:
The utility model relates to a kind of oil hydraulic cylinder, particularly relates to a kind of light-duty double-acting hydraulic cylinder.
background technique:
Double-acting hydraulic cylinder is the most frequently used oil hydraulic cylinder type, provides the stroke of the output of both direction.Double-acting hydraulic cylinder is exactly that two chambeies have oil, and the action of both direction all will realize by oil pressure.The piston of existing double-acting hydraulic cylinder is cylindrical, and own wt is large, installs, dismounting is all very difficult.
summary of the invention:
It is light that the purpose of this utility model is to provide a kind of own wt, the light-duty double-acting hydraulic cylinder that bearing capacity is large.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of light-duty double-acting hydraulic cylinder, comprise cylinder body, piston, piston rod, termination, epicoele oil pipe, lower cavity oil pipe and seal ring, axis hole is provided with in the center of the lower cylinder cap of cylinder body, seal ring is provided with between axis hole and piston rod, the side on cylinder body top is provided with epicoele oil pipe, the side of inferior part of the cylinder block is provided with lower cavity oil pipe, is provided with piston in the cavity between epicoele oil pipe and lower cavity oil pipe, piston is provided with seal ring.The upper end of piston rod is connected with piston, and lower end is connected with termination through axis hole.
Described piston is cylindrical, is provided with cylinder type groove at the upper surface of piston, and the bottom surface of groove is spheric, alleviates the own wt of piston, improves the bearing capacity of piston.The side of piston is provided with upper and lower two grooves, in groove, is provided with seal ring.
The beneficial effects of the utility model are: rational in infrastructure, can alleviate own wt light, easy for installation, and bearing capacity is large, good airproof performance, long service life.
accompanying drawing illustrates:
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1 cylinder body, 2 pistons, 3 piston rods, 4 terminations, 5 epicoele oil pipes, 6 lower cavity oil pipes, 7-8 seal ring.
embodiment:
As shown in Figure 1, a kind of light-duty double-acting hydraulic cylinder, comprise cylinder body (1), piston (2), piston rod (3), termination (4), epicoele oil pipe (5), lower cavity oil pipe (6) and seal ring (7, 8), axis hole is provided with in the center of the lower cylinder cap of cylinder body (1), seal ring (8) is provided with between axis hole and piston rod (3), the side on cylinder body (1) top is provided with epicoele oil pipe (5), the side of cylinder body (1) bottom is provided with lower cavity oil pipe (6), piston (2) is provided with in cavity between epicoele oil pipe (5) and lower cavity oil pipe (6), piston (2) is provided with seal ring (7).The upper end of piston rod (3) is connected with piston (2), and lower end is connected with termination (4) through axis hole.Piston (2), for cylindrical, is provided with cylinder type groove at the upper surface of piston (2), and the bottom surface of groove is spheric, alleviates the own wt of piston (2), improves the bearing capacity of piston (2).The side of piston (2) is provided with upper and lower two grooves, in groove, is provided with seal ring (7).
Working principle: the upper surface of piston (2) is provided with cylinder type groove, the bottom surface of groove is spheric, alleviates the own wt of piston (2), improves the bearing capacity of piston (2).During work, high pressure oil enters through epicoele oil pipe (5) that piston (2) upper chamber promotes piston (2), piston rod (3) and termination (4) move downward, and to workpiece acting, the hydraulic oil in piston (2) lower cavity is discharged through lower cavity oil pipe (6).In the process that piston (2) runs downwards, the upper surface pressurized of piston (2), be spheric structure for upper surface, bearing capacity is large.After work completes, high pressure oil enters through lower cavity oil pipe (6) that piston (2) lower cavity promotes piston (2), piston rod (3) and termination (4) move upward, piston (2) is resetted, and the pressure suffered by piston (2) lower surface is less, can not cause damage.

Claims (2)

1. a light-duty double-acting hydraulic cylinder, comprises cylinder body, piston, piston rod, termination, epicoele oil pipe, lower cavity oil pipe and seal ring, it is characterized in that: described piston is cylindrical, is provided with cylinder type groove at the upper surface of piston, and the bottom surface of groove is spheric.
2. light-duty double-acting hydraulic cylinder according to claim 1, is characterized in that: the side of described piston is provided with upper and lower two grooves, is provided with seal ring in groove.
