Abstract
The invention relates to transmission machinery, in particular to a piston oil cylinder. The piston oil cylinder comprises a cylinder body, a piston, a main rod and an auxiliary rod. The piston is arranged in the cylinder body, one end of the piston is connected with the main rod, and the other end of the piston is connected with the auxiliary rod. The main rod extends out of the cylinder body, the auxiliary rod extends out of the cylinder body, and the piston slides along the inner wall of the cylinder body. The piston oil cylinder ensures that axial stretching of the rods can be accurately controlled under the condition that a shaft rotates, the internal structure is stable, the mobility is good, and the oil cylinder is suitable for the multiple repeated moving law. The smoothness of the inside is improved by means of the lubricating oil, and the stretching is smooth in the back-and-forth direction.
Description
Technical field
The present invention relates to a kind of gearing, relate in particular to a kind of ram cylinder.
Background technique
In gearing field, should guarantee its rotation radially, also will guarantee the movement that it is axial, make two kinds of actions very difficult simultaneously.The technological means of existing solution problems is by screw thread, but screw thread is after the rolling of thousands of times, can cause screw thread stripped thread, and the distance between screw thread broadens and can not accurately control sliding stroke.Also have a kind of ball that passes through, by contact ball, judge stroke, this type of oil cylinder consumption is very fast, just can not touch interior bar and cause control extremely after ball wearing and tearing.
Summary of the invention
The present invention is directed to above-mentioned deficiency a kind of ram cylinder is provided.
The present invention adopts following technological scheme:
A kind of ram cylinder of volume of the present invention, comprises cylinder body, piston, mobile jib, secondary bar; In described cylinder body, be provided with piston, piston one end connects mobile jib, the other end auxiliary connection bar; Mobile jib extends cylinder body, and secondary bar extends cylinder body; Piston slides along inboard wall of cylinder block.
Ram cylinder of the present invention, an outside, top of described cylinder body is provided with flange, and the inner side on another top is provided with bearing, and bearing surface is provided with jacking block to the one end in cylinder body.
Ram cylinder of the present invention, piston is respectively equipped with and is connected piece with the connecting end of mobile jib, secondary bar.
Ram cylinder of the present invention, secondary bar is provided with bite block with one end being connected of piston, and bite block is connected with linking piece.
Ram cylinder of the present invention, described cylinder body is provided with oil transportation hole, bottom near a sidewall of flange.
Ram cylinder of the present invention, described cylinder body is provided with oil transportation hole, top near a sidewall of jacking block.
Ram cylinder of the present invention, fills lubricant oil in described cylinder body.
Beneficial effect
Ram cylinder provided by the invention, can be in the situation that guaranteeing that axle rotates, the axial stretching of accurate controlling rod, and its internal structure is stable, and mobility is good, is applicable to the rule of repetitious movement.Inside increases smoothness by lubricant oil, makes to stretch back and forth more smooth.
