The specific embodiment
As shown in Figure 1; Lathe hydraulic pressure tailstock feeder, the tailstock 1 of lathe is connected with handwheel 6 through connecting leading screw 2, between connection leading screw 2 and handwheel 6, is connected with connecting axle; Connecting axle is inserted in the hydraulic cylinder assembly 5; Handwheel 6 is fixedly connected and is fixed on connecting axle on the hydraulic cylinder assembly 5, and hydraulic cylinder assembly 5 is connected with hand control valve assembly 8, and hand control valve assembly 8 is connected with pumping plant 7.
Said connecting axle comprises little connecting axle 3 and linkage axle 4, and little connecting axle 3 is fixedly connected with being connected leading screw 2 through key 9, and linkage axle 4 is fixedly connected with little connecting axle 3 through straight pin 10.
The tailstock 1 of lathe is the parts on the former lathe with being connected leading screw 2.Little connecting axle 3 is inserted into and connects in the leading screw 2, and end face uses screw 11 lockings, after the aligned in position of connection leading screw 2 and little connecting axle 3 keyways key 9 is inserted in the keyway; Then linkage axle 4 is inserted in the end-face hole of connector bar 3, inserts straight pin 10 behind the positioned in alignment hole.Then linkage axle 4 is inserted in the hydraulic cylinder assembly 5, uses screw 13 to be connected hydraulic cylinder assembly 5 drive end bearing brackets with the silk hole of tailstock end face; And then handwheel 6 is inserted in the axle of linkage axle 4 afterbodys, fixing with linkage axle 4 handwheel 6 through using key 12, end face uses screw fastening again, at last feeder just with tail stock stroke one.In addition, hand control valve block assembly 8 is fixed on hydraulic cylinder assembly 5 drive end bearing brackets through using screw 14, and oil pipe is connected to power unit and oil cylinder rear end, whole system installation.
As shown in Figure 2; Described hand control valve assembly 8 comprise have fuel feed hole 25, the main valve body 18 of spill port 22 and oil duct 21; Be provided with in the main valve body 18 through changing the main valve stem 17 that oil duct changes fluid flow direction; Have in the main valve body 18 to connect oil cylinder ante-chamber oil duct 24 and is connected oil cylinder back cavity oil duct 23, connect oil cylinder ante-chamber oil duct 24 and to be connected oil cylinder back cavity oil duct 23 vertical with main valve stem 17 directions respectively, on the direction vertical, be provided with quick/fine motion switching valve rod 15 with fuel feed hole 25; Fast/fine motion switches valve rod 15 and puts in the fuel feed hole 25; In connecting oil cylinder back cavity oil duct 23, be provided with fine setting valve rod 19, fine setting valve rod 19 is vertical with main valve stem 17 directions, and connection oil cylinder back cavity oil duct 23 communicates with fuel feed hole 25 through oil duct and main valve stem 17.
The front end top one fine setting valve rod ball 20 of described fine setting valve rod 19, fine setting valve rod 19 is threaded with main valve body 18; Fast/front end top one that valve rod 15 is switched in fine motion switches valve rod ball 16, fast/fine motion switches valve rod 15 and is threaded with main valve body 18.
Fuel feed hole 25 on the main valve body 18 is connected with oil return with the oil-feed of hydraulic power unit 7 respectively with spill port 22, connects oil cylinder ante-chamber oil duct 24 and is connected oil cylinder back cavity oil duct 23 and is connected with hydraulic cylinder assembly 5.The commutation function of main valve body 18 is the positions through adjustment main valve stem 17, changes the connection of oil duct 21, thus changed execution unit forward or moving direction backward change.The linear speed regulation function of main valve body 18 mainly is the flow through change oil duct 21, thereby changes the translational speed of execution unit; Fine setting valve rod 19 front ends top one fine setting valve rod ball 20, fine setting valve rod 19 is threaded with main valve body 18, rotates fine setting valve rod 19; Make fine setting valve rod 19 realize moving axially; Like this, the fine setting valve rod ball 20 of its front end also moves axially under the effect of hydraulic pressure thereupon, changes the gap length of fine setting valve rod ball 20 and oil duct port; Thereby changed the flow of hydraulic oil, quick/fine motion is switched the operation principle of valve rod 15 with fine setting valve rod 19.
As shown in Figure 3; When main valve stem 17 is rotated counterclockwise 45 °, fuel feed hole 25 be connected 23 conductings of oil cylinder back cavity oil duct, the execution unit that after the conducting rear end is connected is done corresponding action; The speed of action has dual mode: a kind of is fast moving, and another kind is that fine motion is moved.Continue as shown in Figure 3ly, main valve stem 17 is adjusted to duty forward, and fuel feed hole 25 communicates with being connected oil cylinder back cavity oil duct 23, but the oil duct flow rates controlled in fine setting valve rod 19 with fast/fine motion switches valve rod 15.As shown in Figure 3, when fast/when fine motion was switched valve rod 15 and be open mode, hydraulic oil directly entered into connection oil cylinder back cavity oil duct 23 with very large flow and enters into the oil cylinder back cavity, the execution unit that the rear end is connected moves with very fast speed; When fast/when fine motion is switched valve rod 15 and be closed condition, close oil input channel through switching valve rod ball 16, make the oil pocket of the oil duct inflow rear end execution unit that hydraulic oil can only be through fine setting valve rod 19.
As shown in Figure 4, fine setting valve rod 19 withstands the fine setting valve rod ball 20 of front end through screw thread, thereby adjusts the gap of fine setting valve rod ball 20 and oil duct junction; When the gap is big; Flow is big, and the quick action of execution unit is when gap hour or when very close to each other; Make the translational speed of execution unit slack-off or slack, thereby realized the linear speed regulation that moves of rear end execution unit.
As shown in Figure 5; When main valve stem 17 is in duty forward; Connect oil cylinder ante-chamber oil duct 24 and reflux to spill port 22, make the oil of another oil pocket of execution unit flow back to fuel tank, thereby make execution unit continue to take exercises to a direction through the oil duct on the main valve stem 17.
Like Fig. 6 and shown in Figure 7; When main valve stem 17 when clockwise rotating 45 °, execution unit can move round about, this moment main valve stem 17 be in duty backward; Fast/valve rod 15 is switched in fine motion and fine setting valve rod 19 all cuts little ice, and that is to say that oil can not pass through this two valve rods.At this moment fuel feed hole 25 through the oil duct on the main valve stem 17 directly with is connected oil cylinder ante-chamber oil duct 24 and links to each other past oil cylinder ante-chamber oiling.As shown in Figure 8, when main valve stem 17 is in backward duty, makes spill port 22 again and be connected oil cylinder back cavity oil duct 23 and directly link to each other, make the oil of another oil pocket of execution unit flow back to fuel tank, thereby execution unit is continued to moving in the other direction.
