Abstract
The invention discloses a hydraulic oil cylinder capable of reciprocating automatically. The hydraulic oil cylinder capable of reciprocating automatically comprises an oil inlet channel, an oil outlet channel and a main oil cylinder, wherein the main oil cylinder comprises a cylinder body provided with a step-shaped cavity, a piston is arranged in a big cavity body of the step-shaped cavity in a sliding mode, a piston rod connected with the piston is in sliding fit with a small cavity body of the step-shaped cavity, the oil inlet channel is communicated with the front end of the small cavity body, the oil outlet channel is communicated with the front end of the big cavity body, a hydraulic sliding valve is arranged on the cylinder body in an overlapped mode, the hydraulic sliding valve is provided with a piston cavity and a piston rod cavity, a valve element of the hydraulic sliding valve is in sliding fit with the piston cavity and the piston rod cavity, the oil inlet channel is communicated with the rear end and the upper side wall of the piston rod cavity, the lower side wall of the piston rod cavity is communicated with the rear end of the big cavity body, the front end of the piston cavity is communicated with the small cavity body, and the rear end of the piston cavity is communicated with the front end of the big cavity body. The hydraulic oil cylinder capable of reciprocating automatically has the advantages that the usage space is small, the hydraulic sliding valve is additionally arranged in the overlapped mode based on a traditional oil cylinder, and the oil cylinder can reciprocate automatically and stably by moving the valve element of the hydraulic sliding valve.
Description
Technical field
The present invention relates to technical field of hydraulic oil cylinder, especially a kind of automatic reciprocating type hydraulic jack.
Background technique
At present, known hydraulic jack is to consist of cylinder body, piston etc.By external high pressure oil, realize the motion of oil cylinder, such oil cylinder can only be to a direction motion; And need oil cylinder ceaselessly carrying out to-and-fro motion in some specific occasions, this oil cylinder just can not be satisfied the demand, if make oil cylinder reciprocating motion, just must increase in the outside of oil cylinder the changement as selector valve and so on, the conversion by changement passes in and out the to-and-fro motion that oily direction realizes oil cylinder.The reciprocating oil cylinder of this use selector valve, to-and-fro motion is unstable, and reciprocal stroke can not get good control, and using effect is poor.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, a kind of automatic reciprocating type hydraulic jack lasting, working stability that can keep moving is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of automatic reciprocating type hydraulic jack, comprise oil input channel, oil road, master cylinder, master cylinder comprises the cylinder body with stepped shaft cavity, piston slides and is located in the large chamber of stepped shaft cavity, connecting the piston rod of piston and the loculus of stepped shaft cavity is slidably matched, oil input channel is communicated with described loculus front end, oil road is communicated with described large chamber front end, on described cylinder body, stack is provided with the guiding valve that surges, the guiding valve that surges has piston cavity and rod end chamber, the spool of guiding valve of surging is slidably matched with piston cavity and rod end chamber respectively, oil input channel is communicated with respectively rear end and the upper side wall of rod end chamber, the lower wall of rod end chamber is communicated with large cavity rear end, the front end of piston cavity is communicated with loculus, Yu great chamber, piston cavity rear end front end is communicated with.
The invention has the beneficial effects as follows: the present invention is simple in structure, usage space is little, and it is on the basis of traditional oil cylinder, and the guiding valve that surges superposes, valve element position by the guiding valve that surges moves the automatic reciprocating motion of realizing oil cylinder, has guaranteed the motion stabilization of oil cylinder and stroke is controlled preferably.

Embodiment
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
A kind of automatic reciprocating type hydraulic jack as shown in Figure 1, this hydraulic jack comprises oil input channel 1, oil road 2, master cylinder, master cylinder comprises the cylinder body 3 with stepped shaft cavity, piston 4 slides and is located in the large chamber 5 of stepped shaft cavity, the piston rod 6 that connects piston 4 is slidably matched with the loculus 7 of stepped shaft cavity, oil input channel 1 is communicated with described loculus 7 front ends, and oil road 2 is communicated with described large chamber 5 front ends.
On described cylinder body 3, stack is provided with the guiding valve that surges, the guiding valve that surges has piston cavity 8 and rod end chamber 9, the spool 10 of guiding valve of surging is slidably matched with piston cavity 8 and rod end chamber 9 respectively, oil input channel 1 is communicated with respectively rear end and the upper side wall of rod end chamber 9, the lower wall of rod end chamber 9 is communicated with 5 rear ends, large chamber, the front end of piston cavity 8 is communicated with loculus 7, and piston cavity 8 Yu great chamber, rear end 5 front ends are communicated with.
Working principle is summarized as follows: each letter representation hydraulic fluid port node in figure wherein, to oil input channel 1 oil-feed, there is oil pressure at hydraulic fluid port node K, H, A in oil inlet P, when position in figure always, B mouth on loculus 7 is opened, C mouth pressure release in piston cavity 8, the spool 10 of the guiding valve that makes to surge moves right and E mouth is opened, and joint mouthful E and joint mouthful F are communicated with, G mouth oil extraction on large chamber 5, by oil road 2 exudate force feeds, due to the oil pressure effect of A mouth on loculus 7, piston rod 6 starts to regain; When piston rod 6 moves to A, B joint mouth and communicates, B mouth is opened, to C mouth, pressurize, the spool 10 of guiding valve of surging is moved to the left and closes E mouth, and at this moment H mouth is communicated with F mouth, and G mouth starts oil-feed, G mouth oil pressure increases, promote piston rod 6 and start to stretch out, go round and begin again, thereby realize the automatic reciprocating motion of hydraulic jack.
The present invention is simple in structure, and usage space is little, and it is on the basis of traditional oil cylinder, and the guiding valve that surges that superposes, moves by spool 10 positions of the guiding valve that surges the automatic reciprocating motion of realizing oil cylinder, has guaranteed the motion stabilization of oil cylinder and stroke is controlled preferably.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
