Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in Figure 1: described centrifugal machine scraper drive unit comprises cylinder cap 1, cylinder body 2, first oil-in 3, first piston 4, second oil-in 5, second piston 6, fixed cover 7, female connector 8, guide sleeve 9, adjusting sleeve 10, gland 11, indicating dial 12, sensor block 13, bearing 14, rotating shaft 15, collar 16, adjustment screw 17, holding screw 18, proximity switch 19, first bolt 20, second bolt 21, first outer spiral spline 22, second outer spiral spline 23, spiral shell texturing key 24 in first, second internal thread spline 25 etc.
As shown in Figure 1, the present invention includes cylinder body 2 and be arranged on the rotating shaft 15 of cylinder body 2 inside by bearing 14, cylinder body 2 is provided with the first oil-in 3 and the second oil-in 5, cylinder cap 1 and female connector 8 is respectively equipped with at the two ends of cylinder body 2, fixed cover 7 is set between female connector 8 and cylinder body 2, cylinder body 2, fixed cover 7 and female connector 8 are connected and fixed by the first bolt 20, and the outer end of female connector 8 connects gland 11 by the second bolt 21; Described bearing 14 is fixed on rotating shaft 15 by collar 16, sheathed first piston 4 and the second piston 6 on rotating shaft 15; The outer circumference surface of described rotating shaft 15 is provided with the first outer spiral spline 22, the inner peripheral surface of fixed cover 7 is provided with the second internal thread spline 25, the outer circumference surface that the inner peripheral surface of first piston 4 is provided with the first internal thread spline 24, second piston 6 matched with the first outer spiral spline 22 on rotating shaft 15 is provided with the second outer spiral spline 23 matched with the second internal thread spline 25 on fixed cover 7;
Arrange adjusting sleeve 10 in the inner side of described gland 11 by adjustment screw 17, adjusting sleeve 10 is set on rotating shaft 15, is provided with guide sleeve 9 between adjusting sleeve 10 and rotating shaft 15; Holding screw 18 is provided with between described gland 11 and adjusting sleeve 10;
The two ends of described rotating shaft 15 stretch out cylinder cap 1 and gland 11 respectively, the axle stretch end stretching out gland 11 arranges indicating dial 12, the periphery of indicating dial 12 is installed sensor block 13, the gland 11 of sensor block 13 outer ring installs proximity switch 19 at rotating shaft 15.
Operation principle of the present invention is: pass into hydraulic oil by the first oil-in 3, first piston 4 and the second piston 6 move right in the lump, because fixed cover 7 is fixed on cylinder body 2, under the screw pair effect of fixed cover 7 and the second piston 6, the rotary motion of certain angle is done while moving right, owing to being provided with screw pair between first piston 4 and rotating shaft 15, under the drive of first piston 4, rotating shaft 15 is made to rotate to an angle; Otherwise when the second oil-in 5 passes into hydraulic oil, first piston 4 and the second piston 6, in the lump to left movement, make counter rotational movement at the effect Shaft 15 of above-mentioned two screw pairs; The indicating dial 12 of rotating shaft 15 driven rotary axle 15 axle head while rotary motion rotates, and due to indicating dial 12 outer circumference surface being provided with sensor block 13, sensor block 13 is after proximity switch 19, and proximity switch 19 sends control electric signal.The anglec of rotation of rotating shaft 15 can be realized by the gap between adjusting sleeve 10 and the second piston 6, and concrete operation method is: unclamp adjustment screw 17, and adjustment holding screw 18 makes it hold out against on adjusting sleeve 10 end face.What the rotation due to rotating shaft 15 adopted is that screw pair realizes, and screw pair itself has the function of self-locking.
