As further improvement of the present invention, said input gear shaft is by the clutch shaft bearing and second bearings, and clutch shaft bearing is installed in the lower end of input gear shaft gear parts, and second bearing is installed in the gear upper end, and through the position of packing ring adjusting gear is installed.
As further improvement of the present invention, sealing ring is installed in the said turntable outside, and it is inner to be used to prevent that foreign material from getting into turntable.
As further improvement of the present invention, said mandrel is that rotary hole cooperates in the centre of gyration and the turntable of turntable.
As further improvement of the present invention, the gear parts engagement in said gear and the gear shaft, first packing ring is installed in the rear end of the 4th bearing.
Compared with present technology the present invention has the following advantages:
The present invention is simple and reasonable for structure, last fluted disc, workbench and workpiece three is upwards lifted change moving downward of lower tooth disk into; Since lower tooth disk weight on fluted disc, workbench and workpiece three in light weight, drive also more light and flexible; In addition, because last fluted disc and workbench are only done gyration, can it be supported on the large-sized roller bearing, bearing capacity is bigger than original, and the workpiece revolution steadily.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Following the present invention will combine the embodiment in the accompanying drawing to further describe:
As shown in Figure 1, the present invention mainly by turntable 1, go up fluted disc 2, gear ring 3, input gear shaft 4, pivoting support 5, lower tooth disk 6, piston 7, cylinder body 8, mandrel 9, revolution stage body 10, key 11, sealing ring 12, first lid 13, clutch shaft bearing 14, second bearing 15, first locking nut 16, gear 17, gear shaft 18, the 3rd bearing 19, pad 20, bearing block 21, second locking nut 22, belt pulley 23, first packing ring 24, second lid, 25, second packing ring 26, motor cabinet 27 and the 4th bearing 28 and form.Last fluted disc 2 is connected with turntable 1 through screw, and lower tooth disk 6 is connected with piston 7 through screw; The top and the bottom of pivoting support 5 are connected with revolution stage body 10 with turntable 1 through screw respectively.Mandrel 9 is connected with revolution stage body 10 through screw, and mandrel 9 cooperates as rotary hole in the centre of gyration of turntable 1 and the turntable 1 simultaneously, covers 13 and passes through screw and be connected with mandrel 9, is used to prevent the foreign material entering.Sealing ring 12 is installed in turntable 1 outside, and it is inner to be used to prevent that foreign material from getting into turntable.After piston 7, cylinder body 8 and mandrel 9 cooperate installation, form A, the last lower oil cavitie of B; Piston 7 cooperates through flat key 11 with revolution stage body 10 and prevents that piston 7 from being that the center of circle is turned round with mandrel 9.
Gear ring 3 is connected with turntable 1, the gear parts of input gear shaft 4 and gear ring 3 engagements; The bottom of input gear shaft 4 is equipped with gear 17, and through 16 lockings of first locking nut; The clutch shaft bearing 14 and second bearing 15 are used for supporting input gear shaft 4; Clutch shaft bearing 14 is installed in the lower end of input gear shaft 4 gear parts; Second bearing 15 is installed in gear 17 upper ends; And the position of passing through to install second packing ring, 26 adjusting gears 17, thereby the engagement of the gear parts in guarantee gear 17 and the gear shaft 18.Second lid 25 is connected on the revolution stage body 10 through screw, is used to prevent that foreign material from getting into the inside of revolution stage body.
