Description
Technical field
The present invention relates to bearing machining design field, particularly a kind of cylinder for needle cage orifice punch.
Background technique
At present, general needle cage orifice punch all adopts common cylinder on the market, and as shown in Figure 1, cylinder body 1 is mostly one end sealing, and piston rod 2 is exposed in one end.Main shaft 10 need be considered in using on punch machine structure to be connected with piston rod 2, main shaft is provided with gas hole 11, main shaft 10 needs increase gas hole seal arrangement, the rotation of main shaft 10 and movable in work, the gas hole 11 on main shaft 10 is made to rotate and move, blowning installation cannot be blown to gas hole 11 in fixed position, fixedly brings very large inconvenience to blowning installation, also makes the structure relative complex of rushing fenestra machine.The piston 1 of common cylinder is fixedly connected with piston rod 2 simultaneously, and piston 1 and the rotation of 2 one pieces, piston rod, make piston rod 2 rotate dumb, and also cause cylinder to damage fast, the life-span is short, and piston 1 is also easy to wear, can not adapt to the requirement of frock.
Summary of the invention
For solving the problems of the technologies described above, a kind of simplification is the object of the present invention is to provide to rush Window-Machine structure, piston rod flexible rotation, have blowing function and the high cylinder for needle cage orifice punch of durability.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions: a kind of cylinder for needle cage orifice punch, comprise cylinder body, piston rod and piston, described piston rod is hollow-core construction, and two ends are exposed to outside cylinder body, one end of described piston rod is provided with for installing top screw hole, described piston rod is also provided with two annular slots, two annular springs are installed in described two annular slots respectively, described piston is between two annular springs, join with piston rod is sliding, a thrust-bearing described piston rod is also equipped with, and this thrust-bearing is between described piston and described annular spring.
In order to gas leakage and dust enter when preventing cylinder operation, between described cylinder body two ends and piston rod, be provided with seal ring.
Technique scheme has following beneficial effect: piston rod of the present invention has special construction directly can do main shaft use, has several functions.Piston rod one end is provided with screw hole, directly can connecting top, without the need to connecting main shaft again, simplifying the structure.And piston rod is hollow-core construction, the waste material in processing directly by the hollow air blowing of piston rod, can blow off by blowning installation.Such design makes the position of blowning installation to fix, and piston rod moves and rotates, and blowning installation still can be blown to piston rod without the need to changing position, realizes blowing function.Piston rod is provided with annular slot and annular spring, and piston is located between two annular springs, and join with piston rod is sliding, such design makes piston rod rotate, but piston non rotating, thus make the rotation of piston rod more flexible.Arrange thrust-bearing simultaneously, can reduce the surface friction drag between piston rod and piston, make piston rod rotation flexible, running accuracy is high, and piston is not easy to wear, and improves the durability of cylinder.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of specification, coordinates accompanying drawing to be described in detail to this patent below with the specific embodiment of the present invention.
Accompanying drawing explanation
Fig. 1 is the structural representation of common cylinder.
Fig. 2 is structural representation of the present invention.
Number in the figure illustrates: 1: cylinder body, 2: piston rod, 3: piston, 4: thrust-bearing, 5: annular spring, 6: screw hole, 7: seal ring, 8: the first pores, 9: the second pores, 10: main shaft, 11: gas hole.
Embodiment
As shown in Figure 2, a kind of cylinder for needle cage orifice punch, comprise cylinder body 1, piston rod 2 and piston 3, piston rod 2 is hollow-core construction, and two ends are exposed to outside cylinder body 1, one end of piston rod 2 is provided with for installing top screw hole 6, piston rod 2 is also provided with two annular slots, two annular springs 5 are installed in these two annular slots respectively, piston 3 is between two annular springs 5, join with piston rod 2 is sliding, piston rod 2 is also equipped with a thrust-bearing 4, and this thrust-bearing 4 is between described piston 3 and described annular spring 5.
In addition, between described cylinder body 1 two ends and piston rod 2, be provided with seal ring 7, prevent from leaking gas during cylinder operation.
Cylinder body 1 two ends are respectively equipped with the first pore 8 and the second pore 9, for compressed-air actuated inlet and outlet.Two active chambers are formed between the cylinder body 1 of cylinder and piston 3 both sides.First pore 8 of cylinder body and the second pore 9 alternately have pressurized air inlet and outlet.During work, pressurized air enters in the active chamber of side from the first pore 8 cylinder, thus under air pressure thrust, piston 3 moves to the direction of opposite side active chamber, and the gas of opposite side active chamber is discharged from the second pore 9.Between two annular springs 5 of piston 3 on piston rod 2, piston 3 moves forward, and then promotes piston rod 2 and move forward.Pressurized air enters from the second pore 9, can promote again piston 3 and piston rod 2 to mobile in the other direction, complete reset.Piston 3 is joined with piston rod 2 is sliding, and when piston rod 2 rotates, piston 3 can not rotate, thus makes the rotation of piston rod 2 more flexible.The rotation of piston rod 2 and movement, drive that to be arranged on piston rod 2 top, completes and rush window banging.Piston rod has special construction directly can do main shaft use, has several functions.Piston rod 2 is hollow-core construction, and blowning installation can directly be blown (as shown by arrows) to the hollow position of piston rod 2, and the waste material produced during work, by the hollow-core construction of piston rod 2, blows off by gas.The screw hole 6 of piston rod 2 is directly installed top, and the hollow-core construction of piston rod 2, simplifies the structure of rushing Window-Machine, facilitates the fixing of blowning installation.
By reference to the accompanying drawings embodiments of the present invention are explained in detail above, but the present invention is not limited to above-mentioned mode of execution, in the ken that one skilled in the relevant art possesses, can also make a variety of changes under the prerequisite not departing from present inventive concept.
