Abstract
The invention discloses a telescopic-swivel hydraulic cylinder comprising a cylinder body, a piston and piston rods, wherein the piston rods are arranged at two sides of the piston, a swivel guiding device is arranged between the piston rod on at least one side of the piston and the cylinder and comprises a spiral guiding groove arranged on the piston rod, a limiting plug screw is fixed on the inner wall of the cylinder, matched with the spiral guiding groove and clamped in the spiral guiding groove and can slide along the spiral guiding groove. In the telescopic-swivel hydraulic cylinder, the spiral guiding groove and a limiting pin which are matched with each other are additionally arranged between the piston rod and the cylinder; when the piston rod of the hydraulic cylinder performs rectilinear motion, the limiting pin clamped in the spiral guiding groove is used for driving the piston rod to swivel synchronously so that the piston rod swivels while performing the rectilinear motion. The telescopic-swivel hydraulic cylinder has the advantages of simple structure, reliable action, omittance of an additional mechanism required by completing compound actions, reduction of expenses and improvement of economic benefits.
Description
Technical field
The present invention relates to a kind of oil hydraulic cylinder, especially relate to a kind of flexible rotary type hydraulic cylinder.
Background technique
Oil hydraulic cylinder is the hydraulic actuator that hydraulic pressure can be changed into mechanical energy, when realizing to-and-fro motion with it, can remove speed reducer from, and not have drive gap, and motion is steady, in the hydraulic system of extensive use with various machineries.Conventional cylinder comprises cylinder body, piston and piston rod; Have oil inlet and outlet on the cylinder body; Through the turnover of hydraulic oil, realize the motion of piston and piston rod, realize various control functions through external member again; The motion of this hydraulic rod is the linear type motion, and the external member that is driven is also in company with doing straight line motion.
In actual production process, the many external members that driven by oil hydraulic cylinder not only need rectilinear path, also need spinning movement simultaneously, but oil hydraulic cylinder itself can not be realized spinning movement, and in order to satisfy demand of practical production, the rotary type hydraulic cylinder is just indispensable.At present, the method that generally adopts is through setting up other hydraulic system, perhaps adopts valve group and other other subsidiary bodies to realize the spinning movement of oil hydraulic cylinder, has the complex structure of whole hydraulic system, the shortcoming that cost is higher.
Summary of the invention
To above-mentioned technical problem, the object of the present invention is to provide a kind of flexible rotary type hydraulic cylinder, its have simple in structure, be easy to control, cost is low, can realize that piston rod doing the straight-line characteristics of accomplishing spinning movement simultaneously.
The objective of the invention is to realize through following technological scheme:
A kind of flexible rotary type hydraulic cylinder, it comprises cylinder body, piston and piston rod, and the both sides of said piston are provided with piston rod, and wherein, said piston has at least between piston rod and the cylinder body of a side and is provided with the rotary steering device.
Especially, said rotary steering device comprises the spiral guide slot that is opened on the piston rod, cooperates spiral guide slot on inboard wall of cylinder block, to be fixed with position limit pin, and said position limit pin is stuck in the spiral guide slot and can slides along spiral guide slot.
Especially, said position limit pin is spacing plug screw.
Beneficial effect of the present invention does; Said flexible rotary type hydraulic cylinder is set up spiral guide slot and the position limit pin that cooperatively interacts between piston rod and cylinder body; When the piston rod of oil hydraulic cylinder when doing straight line motion, be stuck in position limit pin in the spiral guide slot and will order about piston rod and rotate simultaneously, compare with conventional cylinder; Not only simple in structure, reliable in action; And saved and accomplished the required additional mechanism providing additional operation of composite move, reduced expense, improved economic benefit.
Description of drawings
According to accompanying drawing and embodiment the present invention is done further explain below.
Fig. 1 is the structural representation of the flexible rotary type hydraulic cylinder of the present invention.
Among the figure:
1, cylinder body; 2, piston rod; 3, piston; 4, rotary sleeve; 5, spacing plug screw; 6, spiral guide slot; 7, cylinder cap; 8, first hydraulic fluid port; 9, second hydraulic fluid port.
Embodiment
Please with reference to shown in Figure 1, Fig. 1 is the structural representation of the flexible rotary type hydraulic cylinder of the present invention.In present embodiment; Said flexible rotary type hydraulic cylinder comprise piston 3, piston rod 2, cylinder body 1 and with first hydraulic fluid port 8 and second hydraulic fluid port 9 of cylinder body 1 intracavity inter-connection; The two ends of said cylinder body 1 are fixed with cylinder cap 7, and said piston rod 2 passes piston 3 and runs through whole cylinder body 1, offer spiral guide slot 6 on the side piston rod 2 of said piston 3; Cooperate spiral guide slot 6 on cylinder body 1 inwall, to be fixed with an end of spacing plug screw 5; The other end of said spacing plug screw 5 is arranged in the spiral guide slot 6, when piston rod 2 is done straight line motion, can drive piston rod 2 by the effect of spacing plug screw 5 and spiral guide slot 6 and implement the turns action.
Working principle is: when oil-feed; From first hydraulic fluid port, 8 incoming pressures oil, pressure oil promotes piston rod 2 setting in motions, at this moment; The spacing plug screw 5 that is stuck in the spiral guide slot 6 will slide along spiral guide slot 6; Under the effect of spacing plug screw 5, piston rod 2 will do the sense of rotation of straight-line while along spiral guide slot 6 begin the rotation, finish up to stroke; When oil return, the principle during with oil-feed is identical, second hydraulic fluid port, 9 incoming pressures oil; Pressure oil promotes piston rod 2 motions, and spacing plug screw 5 slides along spiral guide slot 6, and piston rod 2 begins rotation under the effect of spacing plug screw 5; And the action of rotating when spinning movement and oil-feed is opposite; Thus, piston rod 2 will finish up to stroke doing the straight-line spinning movement of accomplishing simultaneously.
Be appreciated that between piston rod 2 and cylinder body 1 inwall of both sides of said piston 3 and be provided with the spiral guide slot 6 and spacing plug screw 5 that cooperatively interacts.
Above-mentioned flexible rotary type hydraulic cylinder realizes that through the optimization to this body structure of oil hydraulic cylinder piston rod 2 doing the straight-line spinning movement of accomplishing simultaneously; Not only simple in structure, be easy to control; And satisfied work requirements; Saved and accomplished the required additional mechanism providing additional operation of composite move, lowered expense, improved economic benefit.
Above embodiment has just set forth basic principle of the present invention and characteristic, changes according to the change that the position is set of spiral guide slot and spacing plug screw.The present invention is not limited by above-mentioned example, and under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various variations and change, and these variations and change all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
