Described guiding is given prominence to axle and is provided with L shape oilhole, and described L shape oilhole is connected with oil return inlet T 11 by drainback passage A 31.
During work, the dynamic servo oil distribution mechanism be made up of spring 3, chuck 4 and pin rod 6, makes impacting shaft 7 not stop to move reciprocatingly, and forms auto impact.
Operation principle: oil inlet P 10, the oil return inlet T 11 of hydraulic impactor are connected with power station respectively by pipeline, the rated pressure 11MPa of Hydraulic Station, metered flow 30 liters/per minute;
1) prepare to use
During use, as shown in Figure 3, equipment is first with no pressure, and operator is by the cone side pressure of impacting shaft 7 on material to be impacted, and impacting shaft 7, to be in left end point position, can not be moved to the left again;
Chuck 4 left end is by the thrust of spring 3, right-hand member is near pin rod 6(totally 6, be uniformly distributed along the circumference), oil pocket H 26 on the right side of pin rod 6 is communicated with the annular oil groove V 27 on front-bank rotor housing 5, and the annular oil groove V 27 on front-bank rotor housing 5, annular oil groove U 28 connect by the annular oil groove J 20 of impacting shaft 7, and the annular oil groove U 28 on front-bank rotor housing 5 directly connects drainback passage I 14, oil pocket H 26 pressure is 0, stressed on the right side of pin rod 6 is 0, and therefore, chuck 4 is in right end position under the action of the spring;
2) cut-in pressure, equipment is started working.
The endoporus oil pocket N 18 of impacting shaft 7 connects oil inlet passage M 12 by interface channel E 19, interface channel F 22, oil inlet passage R 13, now, and the promotion of the oil that is stressed on the left of impacting shaft 7, lifting surface area S

3)
2/ 4); Step anchor ring (large footpath D1, path D2) place grease chamber on the right side of impacting shaft 7 is communicated with oil inlet passage S 23 by oil inlet passage X 24, the promotion of the oil that is also stressed, anchor ring area S
1=π (D
1 2-D
2 2)/4, but S2>S1, left side driving force is greater than right side, and therefore, impacting shaft 7 is movement rapidly from left to right, impacts material;
3) impacting shaft 7 moves to right and changes the motion of chuck 4
When impacting shaft 7 arrives position shown in Fig. 4, the oil pocket H 26 on the right side of pin rod 6, annular oil groove J 20 are connected to annular oil groove U 28, drainback passage G 17, the oil circuit of drainback passage I 14 is cut off; Pin rod 6 stop.
When impacting shaft 7 continues to advance to position shown in Fig. 5, the annular oil groove J 20 of impacting shaft 7 connects the annular oil groove V 27 on front-bank rotor housing 5, annular oil groove W 29, annular oil groove W 29 on front-bank rotor housing 5 is communicated with oil inlet passage X 24, therefore, oil pocket H 26 cut-in pressure oil on the right side of pin rod 6, fluid drives pin rod 6 to left movement, and therefore, chuck 4 overcomes the movement rapidly of spring force right-to-left under the driving of 6 pin rods;
4) chuck 4 moves to left and joins oil to impacting shaft 7
When chuck 4 arrives position shown in Fig. 6, the drainback passage C 16 between the endoporus oil pocket N 18 of impacting shaft 7 and drainback passage I 14 is cut off; Impacting shaft 7 is braked.
When chuck 4 cross the position shown in Fig. 6 advance to position shown in Fig. 7 time, the endoporus oil pocket N 18 of impacting shaft 7 is communicated with drainback passage I 14 by interface channel E 19, interface channel D 21, drainback passage C 16; Therefore, impacting shaft 7 is rapidly to left movement and arrives left end;
5) impacting shaft 7 moves to left and changes the motion of chuck 4
When impacting shaft 7 gets back to left end to left movement, the spring 3 of chuck 4 left end is for compressive state, on the right side of right-hand member pin rod 6, oil pocket H 26 is through annular oil groove V 27, annular oil groove J 20, annular oil groove U 28, drainback passage G 17, drainback passage I 14, oil pocket H 26 pressure is 0, therefore, chuck 4 is braked and moves right rapidly under the action of the spring; Equipment starts ballistic motion next time.
Additional information:
1) leather cup 9 is glanded 8 and is pressed on the groove of handle set, compressed air is full of in advance in leather cup 9, when impacting shaft 7 right-to-left is return, the flow that equipment needs is little, and system pressure rises, and oil inlet P is by oil inlet passage L pressurising, leather cup 9 is extruded, internal pressure rises, and meanwhile, a part of space outside leather cup is tied up by fluid; When impacting shaft 7 impacts acting from left to right, the flow that equipment needs is comparatively large, and system pressure declines, air expansion work now in leather cup 9, leather cup volume becomes large, again recaptures a part of space, extruded by fluid, enter oil inlet passage M by oil inlet passage L, what strengthen impacting shaft 7 pushes away speed.
2) handle set 1 has the outstanding axle of guiding, impacting shaft 7 plug-in mounting thereon, makes motion more stable, reliable.
3) on handle set 1, the outstanding axle of guiding is provided with L shape oilhole, directly connects oil return inlet T, for regulating the promotion pressure on the left of impacting shaft 7, the hydraulic pressure that may cause during impacting shaft 7 rollback can be prevented stuck simultaneously.
The present embodiment complete machine weight 25-35kg, frequency of impact about 1100 beats/min, ballistic work reaches 50 ~ 200 joules.The construction of orcible entry among a small circle of municipal works, airport maintenance, factory's logistics, the mine disaster relief etc. can be widely used in.
