Abstract
The utility model relates to a hydraulic cylinder with rotary function, which is a fluid pressure actuator. The utility model comprises a cylinder body, a piston and a piston rod, wherein, the cylinder body is provided with oil inlet and outlet openings; a motion assist guide mechanism is arranged between the cylinder body and one end of the piston rod which is extended into the cylinder body. By arranging a rotating mechanism in the hydraulic cylinder, the utility model, the hydraulic cylinder with rotary function is made. The utility model has the advantages that the structure is compact; the use is convenient; the additional mechanism for twofold actions is omitted; the automation control level of a hydraulic control system is enhanced.
Description
The utility model relates to a kind of fluid pressure actuator, specifically a kind of fluid pressure drive device.
In industrial control procedure, using hydraulic control system in large quantities.The core parts of hydraulic control system are oil hydraulic cylinder.Traditional oil hydraulic cylinder includes cylinder body, piston and piston rod, has oil inlet and outlet on the cylinder body.By the turnover of hydraulic oil, realize the motion of piston and piston rod, finish various control functions by external member again.Piston rod in this oil hydraulic cylinder is the linear type motion, and the external member that is driven is also in company with doing straight line motion.And in actual applications, many external members not only need rectilinear path, also need go to action simultaneously.For these special needs, existing single oil hydraulic cylinder then can't address this problem, and just need set up new hydraulic system for this reason, perhaps adopts other control mechanisms to realize This move.So just make the complex structure of commercial plant, cost improves, and the Control work amount increases.
The purpose of this utility model just provides a kind of oil hydraulic cylinder with spinfunction, and promptly piston rod is being done the straight-line while, and also adding has spinning movement, to improve the automatization level of hydraulic control system.
The utility model is achieved in that oil hydraulic cylinder still includes cylinder body, piston and piston rod, has oil inlet and outlet on the cylinder body, is provided with the power-assist guide mechanism that can force the piston rod rotation between piston rod one end that stretches into cylinder body and cylinder body.Promptly utilize the hydraulic coupling of hydraulic system, piston rod is being done the straight-line while, additional rotatablely moving.Design philosophy of the present utility model is that mechanism and oil hydraulic cylinder that the control piston bar rotates are united two into one, and makes a composite hydraulic cylinder, thereby makes piston rod produce compound motion mode.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the local A of Fig. 1 is to unfolded drawing.
Fig. 3 is the structural representation of another implementation of the utility model.
Fig. 4 is that the local B of Fig. 2 is to unfolded drawing.
Embodiment 1: as shown in Figure 1, 2, this oil hydraulic cylinder includes cylinder body 5, piston 10 and piston rod 2.Piston and piston rod can integral body be made, but also split manufacturing, affixed again being integral.On cylinder body 5, have oil inlet and outlet 1,7.Piston 10 is positioned at the middle and lower part of piston rod, and piston-rod lower end inserts cylinder bottom.The power-assist guide mechanism just is arranged on this zone.Its concrete structure is that the lower inside at cylinder body 5 is fixed with cylinder sleeve 9, has two radially relative spiral guide slots 11 on the cylinder sleeve 9.Cross a bearing pin 6 in the piston rod end, be socketed with bearing 8 on two external parts of bearing pin 6, two bearings 8 splits in the spiral guide slot 11 of cylinder sleeve 9.At cylinder body 5 guide sleeves 4 that are equipped with suitable for reading, and give fastening by sealing flange 3.Like this, when hydraulic coupling driven plunger and piston rod were up, bearing 8 was soaring in spiral guide slot, drove bearing pin and piston rod spiral and rose, thereby realized straight line motion and combining of rotatablely moving.The sense of rotation of spiral guide slot 11 and spiral angle are decided according to the real work needs of external member fully.
Embodiment 2: shown in Fig. 3,4, this oil hydraulic cylinder is identical with embodiment 1 substantially, only is that fluting in the power-assist guide mechanism and positioning element are exchanged a upper/lower positions.Be that the power-assist guide mechanism is to have two radially relative spiral guide slots 11 in piston rod 2 lower external face, the semiaxis of in diameter line two ends at cylinder body 5 middle parts are welded with laterally, stretching 6, the inner end of semiaxis 6 is socketed with bearing 8, and bearing 8 splits in the spiral guide slot 11 on piston rod 2.The work of this oil hydraulic cylinder and motion mode and embodiment's 1 is identical, and can save the cylinder sleeve parts.
In above-mentioned two kinds of embodiments, power-assist guide mechanism spacing can be adopted multiple mode.A kind of spiral guide slot can be made closed, with line height on the limited piston bar; Another kind of can the realization by the lower edge and the spacing of piston 10 of guide sleeve 4.Shown in Fig. 1,3, guide sleeve lower edge and piston space so just can guarantee that apart from the following segment length less than piston rod piston rod is not separated with the power-assist guide mechanism, thereby guarantee the functional reliability of oil hydraulic cylinder.
The utility model has been made the oil hydraulic cylinder with spinfunction by steering equipment is made in the oil hydraulic cylinder.This apparatus structure compactness, easy to use, saved the required additional mechanism providing additional operation of dual-action, improved the automatic control level of hydraulic control system.
