CN103801729A, title " hydraulic vibration drill unit ", comprise drill unit mechanism, described drill unit mechanism comprises the first servomotor, left end cap, main shaft, first static-pressure sliding bearing, second static-pressure sliding bearing, shell body, right end cap, flutter body, elasticity end cap and the dop for assembling drill bit, the output shaft of described first servomotor is connected with described main shaft, described shell body inside has cavity volume, described first static-pressure sliding bearing is installed on described shell body cavity volume left end, described second static-pressure sliding bearing is installed on described shell body cavity volume right-hand member, described left end cap is connected with described shell body left end, described right end cap is connected with described shell body right-hand member, described main shaft is successively through left end cap, first static-pressure sliding bearing, cavity volume, second static-pressure sliding bearing and right end cap also stretch out described right end cap, the oil-in of described first static-pressure sliding bearing and the second static-pressure sliding bearing is by the oil-feed flow passage in described shell body, described oil-feed runner is communicated with the oil-in of shell body, the oil-in of described shell body is connected with the oil-out of pressure-reducing valve, described first static-pressure sliding bearing is connected with tank drainback mouth by the oil return runner in the middle part of described shell body with the oil return opening of the second static-pressure sliding bearing, described flutter body is connected with the right-hand member of described main shaft, turnover oilhole is had in the middle part of described flutter body, the oil-out of high-frequency excitation valve is connected with the oil inlet and outlet of shell body, and be communicated with described turnover oilhole with the shaft orientation flowing channel in described main shaft by the turnover runner in shell body, described flutter body right-hand member is connected with elasticity end cap, described flutter body right-hand member and described elasticity end cap left end form one and vibrate cavity volume, described elasticity end cap right-hand member is fixedly connected with dop.Its weak point: one be machining spindle stroke range is fixed, and the scope of application is little; Two is to realize rapid changing knife; Three is that machining accuracy is low.
Utility model content
Purpose of design: avoid the weak point in background technology, design one can meet high-speed motion, there is again high rigidity cutting power, the dead-beat static pressure servo power main tapping manual rapid changing knife structure of the collar bush barrel shell inwall in rack sleeve and main tapping foundry goods shell without frictional movement can be realized again simultaneously.
Design: in order to realize above-mentioned purpose of design.Main shaft adopts tapering screw grafting docking to form by line shaft and splined shaft and the axle center of line shaft and splined shaft is the hollow shaft design of through hole, is technical characteristics of the present utility model.The object of such design is: because the formation line shaft of main shaft and the length of splined shaft are at about 1 meter, if not by its segment design, not only cannot at the through hole of manufacture length in the center of axle at about 1 meter, and the manufacturing cost of the one-piece rotor shaft reaching about 1 meter is very expensive, and be difficult to guarantee its rigidity.What the application was designed to that split docking structure not only can realize line shaft and splined shaft axle center opens hole along long, and the object opening hole in line shaft and splined shaft axle center is achieved, namely the order of rapid changing knife is realized, and greatly reduce the manufacturing cost of axle, ensure that its rigid requirements.
Technical scheme: the manual rapid changing knife structure of a kind of dead-beat static pressure servo power main tapping, hand is made up of pull bar and locking nut, pull bar two ends are shaped with screw thread, and pull bar is positioned at hollow bore main shaft and pull bar front end and cutter spin, rear end is revolved and locked with locking nut.
The utility model is compared with background technology, the split type method design of employing of spline spindle and main shaft, both achieved the object of spline spindle and spindle axis hollow bore, and reduced main shaft and spline spindle production cost, achieve the object of hydraulic power head and the manual rapid changing knife tool of servo power head.
