The utility model content
The utility model is to solve the problems of the technologies described above the rotary table that provides a kind of double-piston to stop tightly to install and be equipped with this to stop tight device.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of double-piston is stopped and is tightly installed, and along the circumferential direction is located at the below of panoramic table, comprises the tight bolt of stopping, the locking oil cylinder of stopping, upper piston, lower piston, the tight sheet of stopping; The said locking oil cylinder of stopping is fixed on the rotary table body; Said locking oil cylinder one end of stopping is provided with pressing plate, and the other end is provided with gland, and the said tight sheet of stopping is fixed on an end of the said locking oil cylinder of stopping through said pressing plate; And said stopping is provided with the gap between tight sheet and the said panoramic table; The said tight bolt of stopping is arranged in " T " shape groove of panoramic table, and end extends in the said locking oil cylinder of stopping, and said upper piston is sleeved on the said tight bolt of stopping; And be arranged on the below of the said tight sheet of stopping; Said lower piston is fixedly connected on the bottom of the said tight bolt of stopping, and said upper piston and said lower piston all can slide up and down along the inwall of the said locking oil cylinder of stopping, said upper piston and saidly stop between the tight bolt, be equipped with back-moving spring between said lower piston and the said gland.
Further, said lower piston is fixed on the said tight bolt of stopping through the nut that is arranged on the said locking oil cylinder gland of stopping.
Further, said stop tight sheet and said stop to be provided with between the locking oil cylinder be used to adjust the said adjustment pad of tight sheet position of stopping.
A kind of NC rotary table comprises the rotary table body, and is arranged on the panoramic table of said rotary table body top, comprises the above-mentioned double-piston tight device of stopping, and the said tight device of stopping along the circumferential direction is located at the below of panoramic table.
The beneficial effect of the utility model is: the utility model through in the panoramic table bottom, the multi-point equispaced installation in the panoramic table body outside tight device of stopping; Realized being stopped tightly simultaneously in the multiple spot position of panoramic table, and this tight device of stopping make convenience simple, easy to maintenance, stop tightly effective, can not cause panoramic table self geometry deformation.

Fig. 2 is the partial enlarged drawing of Fig. 1;
Fig. 3 uses the sketch map of the rotary table of double-piston locking device for the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As depicted in figs. 1 and 2; A kind of double-piston is stopped and is tightly installed, and is fixed with the locking oil cylinder 8 of stopping on the rotary table body 1, and an end of the locking oil cylinder 8 of stopping is provided with pressing plate 11; The other end is provided with gland 4; Upper piston 7 can slide up and down along locking oil cylinder 8 inwalls of stopping with lower piston 6, and upper piston 7 is enclosed within that the T type is stopped on the tight bolt 12 and can does little displacement and slide along the T type tight bolt 12 of stopping, and lower piston 6 is fixed on T type tight bolt 12 bottoms of stopping through two hex nuts 3; The tight sheet 10 of stopping is fixed on the locking oil cylinder 8 of stopping through pressing plate 11, and and said panoramic table bottom between be provided with the gap, the said tight sheet 10 and said stopped is stopped and is provided with pad 9 between the locking oil cylinder 8 and is used to adjust said position of stopping tight sheet 10; Upper piston 7 and T type are stopped and are provided with spring 5 between the tight bolt 12 and between lower piston 6 and the gland 4.
The utility model is stopped and is tightly installed the below that A along the circumferential direction is located at panoramic table 13, is a plurality of standalone modules, and connects (as shown in Figure 3) through pressure oil pipe 2.When described pressure oil pipe 2 supplied pressure oils for the locking oil cylinder 8 of stopping, lower piston 6 promoted the T types tight bolt 12 of stopping and moves down, and upper piston 7 tight sheet 10 tops of will stopping form frictional force to panoramic table 13 bottom surfaces simultaneously, impelled panoramic table 13 to be in the static state tight state of stopping; When the pressure off-load; Lower piston 6, upper piston 7 and the T type tight bolt 12 of stopping hightails down in spring 5 effects, and the tight sheet 10 of stopping forms the gap with the panoramic table bottom surface down at self elastic reaction, i.e. disengaging rubs; This moment, panoramic table 13 releases can be done gyration under associated drives.
