In technique scheme, described drill bushing axle is connected with perforating needle by drill bushing.
In technique scheme, described perforated floor is provided with perforating needle fairlead, and described perforating needle fairlead is provided with the pin hole corresponding with the needle point of perforating needle bottom.
In technique scheme, described punching installing plate both sides fixing front shoe and rear fixed plate in addition in the middle of being fixed with respectively air spring being trapped among.
In technique scheme, described punching cylinder is provided with the punching cylinder mounting holes coordinating with bolt, so that punching cylinder is fixed on cutting head.
In technique scheme, the expansion link of described air spring bottom is fixedly linked by air spring screw and perforated floor.
In technique scheme, described punching cylinder is duplex cylinder.
The perforating device of low noise of the present utility model; there is following beneficial effect: under the air spring guiding of punching installing plate both sides; guarantee that whole perforating device can not produce resonance in cutting machine head high-frequency vibration; make the steadily lifting of whole perforating device; guaranteed punching positioning precision; in this course; each part of perforating device can not collide mutually; the noise producing is very little; and air spring has cushioning effect at punching stroke terminal; perforating device is played a protective role, thereby avoided the damage of punch member.Meanwhile, drilling motor directly connects perforating needle by drill bushing, reduces intermediate transmission link, and perforating needle and drilling motor constant speed are rotated, and has guaranteed perforating efficiency; And when perforating needle breaks or is out of shape because of accident, unclamp drill bushing, just can easily change perforating needle.
Accompanying drawing explanation
Fig. 1 is the structural front view of the perforating device of the utility model low noise;
Fig. 2 is the structure left view of the perforating device of the utility model low noise;
Fig. 3 is the structural representation of A-A section in Fig. 1;
Fig. 4 is the structure upward view of perforated floor in Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.
Referring to Fig. 1, the perforating device of the utility model low noise, comprises punching cylinder 1, drilling motor 2, air spring 3, front shoe 4, punching installing plate 5, drill bushing axle 6, drill bushing 7, perforating needle 8, perforated floor 9, air spring screw 10, rear fixed plate 11, perforating needle fairlead 12.
Described punching cylinder 1 is provided with the punching cylinder mounting holes 13 coordinating with bolt (not shown), punching cylinder 1 is fixed in cutting head (not shown), described punching cylinder 1 is duplex cylinder, and its double-rod structure has guaranteed that perforating device can not affect drilling precision because of revolution.The piston rod bottom of punching cylinder 1 is provided with punching installing plate 5, and described punching cylinder 1 and drilling motor 2 lay respectively at punching installing plate 5 two ends.The clutch end of described drilling motor 2 bottoms is connected with drill bushing axle 6, and described drill bushing axle 6 is connected with perforating needle 8 by drill bushing 7.Drilling motor 2 directly connects perforating needle 8 by drill bushing 7, reduces intermediate transmission link, and the electric 2 machine constant speed of perforating needle 8 and punching are rotated, and has guaranteed perforating efficiency; When perforating needle 8 breaks or is out of shape because of accident, unclamp drill bushing 7 simultaneously, just can easily change perforating needle 8.
Described punching installing plate 5 both sides fixing front shoe 4 and rear fixed plate 11 in addition in the middle of being fixed with respectively air spring 3 tops being trapped among.Due to punching cylinder 1, drilling motor 2 and two air springs 3 are all fixed on punching installing plate 5, form a little construction package, are convenient to detachable maintaining.The expansion link of described air spring 3 bottoms is fixedly linked by air spring screw 10 and perforated floor 9, and described perforated floor 9 is provided with perforating needle fairlead 12, and described perforating needle fairlead 12 is provided with the pin hole corresponding with the needle point of perforating needle 8 bottoms.
Before punching, punching cylinder 1 moves downward, drive punching installing plate 5 and appended parts to move downward together, after perforated floor 9 contacts with cutting fabric (not shown), because continuing to move downward, punching cylinder 1 make air spring 3 pressurizeds produce precompression, cause perforated floor 9 tightly to push down cutting fabric and cannot continue motion downwards, meanwhile, perforating needle 8 continues to move downward under the effect of punching cylinder 1, until contact with cutting fabric and start to punch through the pin hole of perforating needle fairlead 12.When running to stroke terminal, punching cylinder 1 make punching while having moved, punching cylinder 1 piston rod is retracted, punching installing plate 5 and appended parts move up together, perforating needle 8 leaves cutting fabric, perforated floor 9 is also tightly pushed down cutting fabric under air spring 3 precompressions, until reset under air spring 3 reset pulling force effects.In whole punching process, under both sides air spring 3 guiding, steadily lifting of perforating device, has guaranteed that punching accurate positioning, precision are high; Cushioning effect due to air spring 3; guaranteed that whole perforating device can not produce resonance in cutting machine head height frequency vibration; and the part of perforating device self can not collide mutually yet; make the noise of generation very little; whole perforating device has also been played to protective effect, avoided perforating device to be damaged.
