Abstract
The utility model relates to transmission machinery, in particular to a piston type oil cylinder. The piston type oil cylinder comprises a cylinder body, a piston, a main rod and an auxiliary rod, wherein the piston is arranged in the cylinder body, one end of the piston is connected with the main rod, 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 type oil cylinder can accurately control axial extension and retraction of the rods on the premise of guaranteeing rotation of a shaft, is stable in inner structure, good in mobility, and suitable for a rule of repetitious movements, and enables repeating extension and retraction to be fluent due to the fact that smoothness of the interior of the piston type oil cylinder is improved through lubricating oil.
Description
Technical field
The utility model relates to a kind of gearing, relates 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 one by ball, judge stroke by contact ball, this type of oil cylinder consumption is very fast, just can not touch interior bar and cause control abnormal after ball wearing and tearing.
Model utility content
The utility model provides a kind of ram cylinder for above-mentioned deficiency.
The utility model adopts following technological scheme:
A kind of ram cylinder of volume described in the utility model, 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 described in the utility model, 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 described in the utility model, piston is respectively equipped with and is connected piece with the connecting end of mobile jib, secondary bar.
Ram cylinder described in the utility model, secondary bar is provided with bite block with one end being connected of piston, and bite block is connected with linking piece.
Ram cylinder described in the utility model, described cylinder body is provided with oil transportation hole, bottom near a sidewall of flange.
Ram cylinder described in the utility model, described cylinder body is provided with oil transportation hole, top near a sidewall of jacking block.
Ram cylinder described in the utility model, fills lubricant oil in described cylinder body.
Beneficial effect
The ram cylinder that the utility model provides, can be in the situation that guaranteeing that axle rotates, the accurately axial stretching of 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in the figure: a kind of ram cylinder, comprises cylinder body 1, piston 2, mobile jib 3, secondary bar 4; In described cylinder body 1, be provided with piston 2, piston 2 one end connect mobile jib 3, the other end auxiliary connection bar 4; Mobile jib 3 extends cylinder body 1, and secondary bar 4 extends cylinder body 1; Piston 2 slides along cylinder body 1 inwall.One outside, top of cylinder body 1 is provided with flange 11, and the inner side on another top is provided with bearing 5, and bearing 5 is provided with jacking block 10 towards the one end in cylinder body 1.
Piston 2 is respectively equipped with and is connected piece 6 with the connecting end of mobile jib 3, secondary bar 4.Secondary bar 4 is provided with bite block 9 with one end being connected of piston 2, and bite block 9 is connected with linking piece 6.Cylinder body 1 is provided with oil transportation hole 7, bottom near a sidewall of flange 11.Cylinder body 1 is provided with oil transportation hole, top 8 near a sidewall of jacking block 10.The interior filling lubricant oil of cylinder body 1.
