As shown from the above technical solution, the present invention has adopted and has used pull bar to assemble the technological scheme of cylinder body, thereby the bigger oil cylinder integral body of difficulty of processing, split into a plurality of component that are easy to process, not only reduce difficulty of processing, and be convenient to assembling, improved manufacturing speed greatly, simultaneously reduce manufacture cost significantly, also helped the maintenance in the oil cylinder using process in the future.This shows that the present invention is easy to process, assembling is simple, cost is low and be easy to maintenance.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A sectional view among Fig. 1.
Embodiment
As shown in Figure 1, 2, a kind of novel oil cylinder, cylinder cap 20 and cylinder bottom 30 that this oil cylinder comprises cylinder barrel 10 and is positioned at cylinder barrel 10 two ends, be provided with the inner chamber of connection cylinder barrel 10 and the oil duct of oil cylinder outside oil feed line on cylinder cap 20 and the cylinder bottom 30, the piston head 41 of piston rod 40 is positioned at cylinder barrel 10, one side of piston head 41 is provided with the body of rod 42, the body of rod 42 is along the direction extension of cylinder barrel 10 qualifications and the outside of stretching out oil cylinder, described cylinder barrel 10, cylinder cap 20 and cylinder bottom 30 are independent component, and the three tightens together by pull bar 50.
As previously mentioned, the present invention is split as the whole cylinder body cylinder barrel 10, cylinder cap 20 and the cylinder bottom 30 that is easy to manufacturing, during assembling piston rod 40 is put into cylinder barrel 10, again the two ends of cylinder barrel 10 are inserted in cylinder cap 20 and the cylinder bottom 30, with pull bar 50 cylinder cap 20, cylinder barrel 10 and cylinder bottom 30 are connected as a single entity again, because be provided with the inner chamber of connection cylinder barrel 10 and the oil duct of oil cylinder outside oil feed line on cylinder cap 20 and the cylinder bottom 30, the oil cylinder after therefore assembling finishes just can come into operation.This shows, the present invention easy to process and be easy to the assembling, improved the manufacturing efficiency of oil cylinder greatly, correspondingly with it be, when needs carry out maintenance and inspection to cylinder body, then it can be taken apart, thereby can carefully check its internal structure, so the present invention also is very easy to the maintenance of oil cylinder.
Described chimeric connection also promptly makes the two ends of cylinder barrel 10 and cylinder cap 20 and cylinder bottom 30 combine mutually in the mode of inlaying, and adopts among the present invention to be threaded or chimeric ways of connecting can improve the assembling speed of cylinder body.
As another kind of preferred version of the present invention, as shown in Figure 2, the two ends place of described cylinder barrel 10 is provided with the concave station of ring-type, and the concave station place is provided with Sealing 11.
Being provided with of Sealing 11 can prevent hydraulic oil in the cylinder body through the place, two ends of cylinder barrel 10 seepage, thereby can guarantee the work that oil cylinder can safety and stability.
As preferred version of the present invention, described cylinder barrel 10 is processed by steel pipe.
Steel strength is high and satisfy the usage requirement of oil cylinder, can also provide in a large number in the mode of finished product, thereby has further improved manufacturing efficiency of the present invention.
As shown in Figure 1, described pull bar 50 is arranged on the outside of cylinder barrel 10, and the shaft of pull bar 50 is parallel with the medial axis of cylinder barrel 10.
In described pull bar 50 and cylinder cap 20 and the cylinder bottom 30 any one is for being threaded, and pull bar 50 passes another and is connected with nut 51, and pull bar 50 and nut 51 match cylinder cap 20, cylinder barrel 10 and cylinder bottom 30 threes are connected as one.
With Fig. 2 is example, the two ends of pull bar shown in the figure 50 all are provided with screw thread, the one end is screwed in the screw with cylinder cap 20, the other end of pull bar 50 passes the body of cylinder bottom 30, and be connected with the nut 51 of cylinder bottom 30 opposite sides, and twist pressure by the rotation of nut 51 on pull bar 50, just cylinder cap 20, cylinder barrel 10 and cylinder bottom 30 threes closely can be connected as one.
As the further preferred version of the present invention, as shown in Figure 2, on described cylinder cap 20 or cylinder bottom 30 and the anchor ring that the body of rod 42 of piston rod 40 pastes mutually, be provided with a plurality of annular recess equably, be provided with Sealing 43 in the described groove along the bearing of trend of the body of rod 42.
Sealing 43 in these a plurality of annular recess can guarantee that the hydraulic oil in the oil cylinder can not guarantee the stable operation of piston rod 40 simultaneously through the junction generation seepage of the body of rod 42 with oil cylinder.
