Detailed description of the invention
As shown in Figure 1, lathe hydraulic tailstock feeder, the tailstock 1 of lathe is connected with handwheel 6 by connecting leading screw 2, connecting axle is connected with between connection leading screw 2 and handwheel 6, connecting axle is inserted in hydraulic cylinder assembly 5, handwheel 6 is fixedly connected with connecting axle and is fixed on hydraulic cylinder assembly 5, and hydraulic cylinder assembly 5 is connected with Non-follow control valve assembly 8, and Non-follow control valve assembly 8 is connected with pumping plant 7.
Described connecting axle comprises little connecting axle 3 and large connecting axle 4, little connecting axle 3 by key 9 be connected leading screw 2 and be fixedly connected with, large connecting axle 4 is fixedly connected with little connecting axle 3 by straight pin 10.
The tailstock 1 of lathe is parts on former lathe with being connected leading screw 2.Little connecting axle 3 is inserted into and connects in leading screw 2, and end face uses screw 11 to lock, and is inserted in keyway after connecting the aligned in position of leading screw 2 and little connecting axle 3 keyway by key 9; Then large connecting axle 4 is inserted in the end-face hole of connector bar 3, behind positioned in alignment hole, inserts straight pin 10.Then large connecting axle 4 is inserted in hydraulic cylinder assembly 5, uses screw 13 that hydraulic cylinder assembly 5 drive end bearing bracket is connected with the silk hole of tail-holder end face; And then be inserted into by handwheel 6 in the axle of large connecting axle 4 afterbody, by using key 12 that handwheel 6 and large connecting axle 4 are fixed, end face uses fastened by screw again, last feeder just with tail stock stroke integrally.In addition, hand control valve block assembly 8 is fixed on hydraulic cylinder assembly 5 drive end bearing bracket by 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 Non-follow control valve assembly 8 comprises and has fuel feed hole 25, the main valve body 18 of spill port 22 and oil duct 21, the main valve stem 17 by changing oil duct and alter flow direction is provided with in main valve body 18, have in main valve body 18 and connect oil cylinder ante-chamber oil duct 24 and be 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 direction respectively, the direction vertical with fuel feed hole 25 is provided with fast/fine motion and switches valve rod 15, fast/fine motion switches valve rod 15 and puts in fuel feed hole 25, fine setting valve rod 19 is provided with in connection oil cylinder back cavity oil duct 23, fine setting valve rod 19 is vertical with main valve stem 17 direction, and connection oil cylinder back cavity oil duct 23 is communicated with fuel feed hole 25 by oil duct and main valve stem 17.
Top, the front end 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; The top, front end one that fast/fine motion switches valve rod 15 switches valve rod ball 16, and fast/fine motion switches valve rod 15 and is threaded with main valve body 18.
Fuel feed hole 25 on main valve body 18 and spill port 22 are connected with the oil-feed of hydraulic power unit 7 and oil return respectively, connect oil cylinder ante-chamber oil duct 24 and are connected oil cylinder back cavity oil duct 23 and are connected with hydraulic cylinder assembly 5.The commutation function of main valve body 18 is the positions by adjusting main valve stem 17, changes the connection of oil duct 21, thus changes execution unit moving direction change forward or backward.The linear speed regulation function of main valve body 18, mainly by changing the flow of oil duct 21, thus changes the translational speed of execution unit; Fine setting valve rod 19 front end top one fine setting valve rod ball 20, fine setting valve rod 19 is threaded with main valve body 18, rotate fine setting valve rod 19, fine setting valve rod 19 is made to 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, thus changing the flow of hydraulic oil, fast/fine motion switches 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 the conducting of oil cylinder back cavity oil duct 23, the execution unit that rear end can be made to connect after conducting does corresponding action, the speed of action has two kinds of modes: one is quick movement, and another kind is that fine motion is moved.Continue as shown in Figure 3, duty forward adjusted to by main valve stem 17, fuel feed hole 25 with is connected oil cylinder back cavity oil duct 23 and communicates, but oil duct flow rates controlled is in fine setting valve rod 19 and quick/fine motion switching valve rod 15.As shown in Figure 3, when fast/fine motion switching valve rod 15 is open mode, hydraulic oil directly enters into connection oil cylinder back cavity oil duct 23 with very large flow and enters into oil cylinder back cavity, and the execution unit that rear end is connected moves with speed quickly; When fast/fine motion switching valve rod 15 is closed condition, closing oil input channel by switching valve rod ball 16, making hydraulic oil can only be flowed into the oil pocket of rear end execution unit by the oil duct of 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 by screw thread, thus the gap of adjustment fine setting valve rod ball 20 and oil duct junction, when the gap is large, flow is large, the quick action of execution unit, when the gap is small or very close to each other time, make the translational speed of execution unit slack-off or slack, thus achieve the linear speed regulation of the movement 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 to be refluxed to spill port 22 by the oil duct on main valve stem 17, make the oil of another oil pocket of execution unit flow back to fuel tank, thus make execution unit continue to take exercises to a direction.
As shown in Figure 6 and Figure 7, when main valve stem 17 is to when rotating clockwise 45 °, execution unit can move round about, and now main valve stem 17 is in backward operation state, fast/fine motion switches valve rod 15 and fine setting valve rod 19 all cuts little ice, and that is oil can not pass through these two valve rods.At this moment fuel feed hole 25 by the oil duct on main valve stem 17 directly with is connected oil cylinder ante-chamber oil duct 24 and is connected, past oil cylinder ante-chamber oiling.As shown in Figure 8, while main valve stem 17 is in backward operation state, makes again spill port 22 and be connected oil cylinder back cavity oil duct 23 and be directly connected, make the oil of another oil pocket of execution unit flow back to fuel tank, thus execution unit is continued to mobile in the other direction.
