The specific embodiment
Below in conjunction with accompanying drawing the embodiment of rifle of the present invention with hydraulic bjuffer is further described.Those of ordinary skill in the art can recognize, in the situation that without departing from the spirit and scope of the present invention, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used for the protection domain of restriction claim.In addition, in this manual, accompanying drawing draws not in scale, and identical Reference numeral represents identical part.
As depicted in figs. 1 and 2, the rifle of the present invention rear plug 10 that comprises cylindrical shell 5, be arranged on the front plug 3 of cylindrical shell 5 one ends and be arranged on cylindrical shell 5 other ends with hydraulic bjuffer.Piston 1 comprises piston rod 101 and pistons end 102.Front plug 3 is provided with piston hole, and piston rod 101 is by behind the piston hole of front plug 3, and pistons end 102 is installed in the cylindrical shell 5, and piston 1 can slide at cylindrical shell 5 and front plug 3 interior length directions along cylindrical shell 5.Be provided with sealing ring 2 between piston rod 101 and the front plug 3.
As shown in Figure 1, valve 4 is installed in the pistons end 102, and relative motion before and after can doing in pistons end 102, along the length direction of cylindrical shell 5, and the hole is carried out spacing with 6 pairs of valve of back-up ring 4, in order to avoid valve 4 drops out pistons end 12 in motion process.
As shown in Figure 1, in cylindrical shell 5, be provided with back-moving spring 7 between pistons end 102 and the rear plug 10, be used for buffering and finish resetting of back piston 1.
As shown in Figure 1, be provided with backing pin 8, steel ball 9 and screw hole 12 on the rear plug 10, backing pin 8 is used for carrying out spacing to steel ball 9.Screw hole 12 also is oil filler point simultaneously, after the hydraulic bjuffer assembling is finished, and from screw hole 12 injection liquid force feeds, the screw 11 and screw can be with this hydraulic bjuffer sealing of then packing into.Steel ball 9 plays the effect of non-return valve in this hydraulic bjuffer, during oiling, steel ball 9 moves to the direction of backing pin 8 under the effect of hydraulic oil, thereby opens oil filler point, and hydraulic oil is entered in the cylindrical shell 5.After oiling was finished, steel ball 9 sealed the end of screw hole 12 under the effect of hydraulic oil, thereby prevented that hydraulic oil from flowing out.
As shown in Figure 2, the root of piston rod 101 is provided with fluid hole 103, and the present embodiment preferably arranges four equidistant fluid holes 103, to guarantee the unimpeded of running of hydraulic power oil.
As shown in Figure 3, the center of valve 4 is provided with center fluid hole 401, and both sides are provided with side fluid hole 402, and described center fluid hole 401 is less, and side fluid hole 402 is larger.
Describe the course of work that rifle of the present invention is used hydraulic bjuffer in detail below in conjunction with accompanying drawing.
As shown in Figure 4, when automatic machine percussion piston 1, piston 1 is along A to moving, and simultaneously, the hydraulic oil in the cylindrical shell 5 is along B to flowing.Valve 4 is adjacent to the inner face 104 of pistons end 102 under the effect of hydraulic fluid pressure, thereby side fluid hole 402 is closed, the chamber that hydraulic oil can only flow between pistons end 102 and the front plug 3 from the center fluid hole 401 of valve 4, because the diameter of center fluid hole 401 is less, hydraulic oil will produce larger damping, thereby piston 1 has been produced preferably cushioning effect.Simultaneously, piston 1 along A in the process of moving, back-moving spring 7 is compressed under the effect of piston 1, has stored energy.
As shown in Figure 5, after automatic machine begins to advance again, piston 1 begins to reset under the effect of back-moving spring 7, piston 1 moves along A ＇ direction under the promotion of back-moving spring 7, hydraulic oil in the cylindrical shell 5 flows along B ＇ direction, valve 4 is used the direction motion of back-up ring 6 to the hole under the effect of hydraulic fluid pressure, this moment, the side fluid hole 402 of valve 4 both sides was in open state, hydraulic oil flows to chamber between pistons end 102 and the rear plug 10 by center fluid hole 401 and side fluid hole 402 from the chamber between pistons end 102 and the front plug 3 rapidly, hydraulic oil produces less damping, thereby piston 1 is resetted as early as possible, prepare to bear bump next time.Simultaneously, be arranged on four fluid holes 103 of piston rod 101 roots, guaranteed that also hydraulic oil can be rapidly flows to chamber between pistons end 102 and the rear plug 10 from chamber between pistons end 102 and the front plug 3, thereby guaranteed reset speed and the effect of piston 1.
Rifle of the present invention is mainly determined by the diameter of the center fluid hole 401 of valve 4 and the effect stroke of piston 1 with the damping characteristics of hydraulic bjuffer, can according to the different recoil energy of firearms, regulate impulse stroke and center fluid hole diameter and mate.Concrete size can be determined by theoretical calculation and test, theoretical calculating referring to relevant books such as cannon recoil absorber designs.In the present embodiment, the diameter of center fluid hole 401 is 1 millimeter, and the impulse stroke of piston 1 is 8 millimeters, and cylindrical shell is installed in the gun stock of certain novel machine gun.Test shows, it is that the speed that the automatic machine recoil of 650g puts in place is decreased to 2.1m/s by 5.7m/s that this rifle can make quality with hydraulic bjuffer, and preferably buffering effect is arranged.The present embodiment back-moving spring spring power is 19.7N, and test shows can satisfy the continuous fire requirement that radio frequency is certain novel machine gun of 780/minute.
As mentioned above, rifle of the present invention is small and exquisite, simple and compact for structure, easy for installation with the hydraulic bjuffer volume, and reset speed is fast, good buffer effect, and can by the different technical parameter of design, make the applicable different firearms buffering requirement of this hydraulic bjuffer.
