The marked stroke-adjustable air cylinder has the advantages of simple structure, reasonable arrangement, low manufacturing cost and the like.
Description
Technical field
The present invention relates to a kind of cylinder technical field, particularly a kind of band scale increased stroke-adjustable gas cylinder.
Background technique
In the Pneumatic Transmission pressure energy of pressurized gas is converted to the pneumatic apparatus of mechanical energy.Cylinder has does two classes linear reciprocating motion and that do reciprocally swinging.The cylinder of doing linear reciprocating motion can be divided into again 4 kinds of single-acting, double-action, diaphragm type and blow cylinders.
At present, traditional linear reciprocating motion cylinder is the cylindrical metal parts that adopt the guiding piston to carry out therein straight reciprocating motion, and it mainly is comprised of cylinder barrel, end cap, piston, piston rod and Sealing.This traditional cylinder can be deposited the shortcomings such as error is large, to-and-fro motion stroke adjustment difficulty in precise control system, simultaneously, also can't show current stroke value.Therefore, how to improve the fine adjustment of cylinder stroke, how to show current stroke value, being convenient to the problem such as field management has become the in the industry focus of research.
Summary of the invention
The object of the invention is to defective and deficiency for prior art, band scale increased stroke-adjustable gas cylinder a kind of simple in structure, reasonable in design, easy to use is provided.
For achieving the above object, the technical solution used in the present invention is:
A kind of band scale increased stroke-adjustable gas cylinder of the present invention, comprise cylinder barrel, be provided with piston in the described cylinder barrel, described piston and inner wall of cylinder closely cooperate, the bottom nozzle of described cylinder barrel is provided with end cap, described piston is connected with the piston rod that is arranged on the cylinder barrel outside, bottom and the top of described cylinder barrel are respectively arranged with valve, described valve axially arranges along cylinder barrel, the outer wall surface of described piston rod is carved with the axial graduation line of five equilibrium, the piston rod outer wall surface that is carved with axial graduation line also is provided with outside thread, described piston rod is set with Adjusting ring, the outside thread of described piston rod is connected with the internal thread of described Adjusting ring, and the outer wall surface of described Adjusting ring is carved with the radially graduation line of five equilibrium.
Further, the part that closely cooperates of described piston rod and described cylinder barrel, end cap all is nested with seal ring.
Further, the range of described axial graduation line is 0～50mm.
Further, the range of described radially graduation line is 0～1mm.
After adopting said structure, beneficial effect of the present invention is: a kind of band scale increased stroke-adjustable gas cylinder of the present invention, comprise cylinder barrel, be provided with piston in the described cylinder barrel, described piston and inner wall of cylinder closely cooperate, the bottom nozzle of described cylinder barrel is provided with end cap, described piston is connected with the piston rod that is arranged on the cylinder barrel outside, bottom and the top of described cylinder barrel are respectively arranged with valve, described valve axially arranges along cylinder barrel, the outer wall surface of described piston rod is carved with the axial graduation line of five equilibrium, the piston rod outer wall surface that is carved with axial graduation line also is provided with outside thread, described piston rod is set with Adjusting ring, and the outside thread of described piston rod is connected with the internal thread of described Adjusting ring, and the outer wall surface of described Adjusting ring is carved with the radially graduation line of five equilibrium.Use when of the present invention, according to axial graduation line and the position that rotates Adjusting ring of the scale on the graduation line radially, the stroke of control cylinder exactly, and can show current stroke value, make things convenient for field management.The advantages such as the present invention has simple in structure, arranges rationally, and fabricating cost is low.
