During work,, make that impacting shaft 7 does not stop to move reciprocatingly, form automatically and impact by the dynamic servo oil distribution mechanism that spring 3, chuck 4 and pin rod 6 constitute.
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, 30 liters/per minute of metered flow;
1) prepares to use
During use, as shown in Figure 3, equipment does not at first have pressure, and the operator is pressed in the awl end of impacting shaft 7 on the material to be impacted, and impacting shaft 7 can not be moved to the left to be in the left end point position again;
Chuck 4 left ends are subjected to the thrust of spring 3, right-hand member is near totally 6 of pin rod 6(, be uniformly distributed along the circumference), the oil pocket H 26 on pin rod 6 right sides is communicated with the annular oil groove V 27 on the front- bank rotor housings 5, and 20 of the annular oil groove J of impacting shaft 7 connect the annular oil groove V 27 on the front-bank rotor housing 5, annular oil groove U 28, and the annular oil groove U 28 on the front-bank rotor housing 5 directly connects drainback passage I 14, oil pocket H 26 pressure are 0, pin rod 6 right sides are stressed to be 0, and therefore, chuck 4 is in right end position under spring action;
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, at this moment, and the be stressed promotion of oil of impacting shaft 7 left sides, lifting surface area S

2/ 4); The step anchor ring on impacting shaft 7 right sides (big directly D1, path D2) grease chamber, place is communicated with the promotion of the oil that also is stressed, anchor ring area S with oil inlet passage S 23 by oil inlet passage X 24
1=π (D
1 2-D
2 2)/4, but S2〉S1, the left side driving force is greater than the right side, and therefore, impacting shaft 7 moves 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 arrived position shown in Figure 4, the oil circuit that the oil pocket H 26 on pin rod 6 right sides, annular oil groove J 20 are connected to annular oil groove U 28, drainback passage G 17, drainback passage I 14 was cut off; Pin rod 6 stop.
When impacting shaft 7 continues when advance in position shown in Figure 5, the annular oil groove J 20 of impacting shaft 7 connects the annular oil groove V 27 on the front-bank rotor housing 5, annular oil groove W 29, annular oil groove W 29 on the front-bank rotor housing 5 is communicated with oil inlet passage X 24, therefore, the oil pocket H 26 cut-in pressure oil on pin rod 6 right sides, fluid drives pin rod 6 to left movement, and therefore, chuck 4 overcomes the spring force right-to-left and moves rapidly under the driving of 6 pin rods;
4) the chuck 4 impact axle 7 that moves to left is joined oil
When chuck 4 arrived position shown in Figure 6, the endoporus oil pocket N 18 of impacting shaft 7 and the drainback passage C 16 between the drainback passage I 14 were cut off; Impacting shaft 7 brakings.
When chuck 4 is crossed position shown in Figure 6 when advance in position shown in Figure 7, 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 moves left rapidly and arrives left end;
5) impacting shaft 7 moves to left and changes the motion of chuck 4
When impacting shaft 7 is got back to left end to left movement, the spring 3 of chuck 4 left ends is for compressive state, right-hand member pin rod 6 right side oil pocket H 26 are 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 are 0, therefore, chuck 4 is braked rapidly and is moved right under spring action; Equipment begins ballistic motion next time.
Supplemental instruction:
1) leather cup 9 is glanded 8 and is pressed on the groove of handle set, prefilled compressed air in the leather cup 9, when impacting shaft 7 right-to-lefts are 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 simultaneously, the outer a part of space of leather cup is tied up by fluid; When impacting shaft 7 impacted acting from left to right, the flow that equipment needs was bigger, and system pressure descends, leather cup 9 interior air expanded and did work this moment, and it is big that the leather cup volume becomes, and recaptures a part of space again, fluid is extruded, entered oil inlet passage M, strengthen the speed that pushes away of impacting shaft 7 by oil inlet passage L.
2) the outstanding axle of guiding is arranged on the handle set 1, impacting shaft 7 plug-in mountings make motion more stable, reliable thereon.
3) the outstanding axle of guiding is provided with L shaped oilhole on the handle set 1, directly connects oil return inlet T, is used to regulate the promotion pressure in impacting shaft 7 left sides, and the hydraulic pressure that may cause in the time of can preventing impacting shaft 7 rollbacks simultaneously is stuck.
Present embodiment complete machine weight 25-35kg, about 1100 times/minute of frequency of impact, ballistic work reaches 50～200 joules.Can be widely used in the construction of orcible entry among a small circle of municipal works, airport maintenance, factory's logistics, the mine disaster relief etc.
