A kind of bistrique slewing equipment is characterized in that: comprise base, panoramic table, worm screw, worm gear, angular encoder, centration axis, elasticity cylinder body and brake ring; Said base and lathe mill frame slide plate are affixed; Said base is connected with said panoramic table is coaxial; Said worm screw and base are affixed, and said worm gear and panoramic table are affixed, and said worm screw and said worm gear are connected; Said angular encoder is coaxial affixed with base, and said angular encoder is positioned on the centre of gyration line of base; Said centration axis is coaxial affixed with panoramic table, and said centration axis is positioned on the centre of gyration line of panoramic table; Said angular encoder and said centration axis are connected; Said elasticity cylinder body and base are affixed, and said elasticity cylinder body is between base and panoramic table; Said brake ring is arranged between worm gear and the base, and said brake ring and worm gear are affixed.

Further, be provided with the turntable bearing between said base and said panoramic table.

Further, said angular encoder comprises stationary part and rotor portion, and said stationary part is fixedly connected through fixed disk with base.

Further, the rotor portion of said angular encoder is sheathed on outside the said centration axis, and said rotor portion is fixedly connected with said centration axis.

The utility model drives worm screw through external impetus, drives the worm gear revolution, has realized automatic revolute function; Through angular encoder monitoring angle, sender; Realize the automatic clamping and the closed-loop control of bistrique through the design of elasticity cylinder body and brake block; Compare with the manual adjustments control angle of revolution of prior art, the utility model global design automaticity height and performance are stable again, precision is high, efficient is high.

Description of drawings

Accompanying drawing is used to provide the further understanding to the utility model, and constitutes the part of specification, is used to explain the utility model with the embodiment of the utility model, does not constitute the restriction to the utility model.In the accompanying drawings:

Fig. 1 is the prior art constructions sketch map;

Fig. 2 is the structural representation of the utility model bistrique slewing equipment;

The specific embodiment

Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.

Embodiment 1

As shown in Figure 2, a kind of bistrique slewing equipment comprises base 2, panoramic table 5, worm screw 3, worm gear 4, centration axis 6, angular encoder 7, elasticity cylinder body 9 and brake ring 10; Base 2 is fixedly connected with lathe mill frame slide plate, and base 2 is connected with panoramic table 5, and base 2 has same centre of gyration line with panoramic table 5.

Base 2 is provided with worm screw 3, elasticity cylinder body 9, fixed disk 8 and angular encoder 7.

Panoramic table 5 is provided with worm gear 4, centration axis 6 and bistrique 1.

Worm screw 3 is affixed with base 2, and worm screw 3 is positioned at a side of base, the external power set of an end; Worm gear 4 is coaxial affixed with panoramic table 5, rotates with panoramic table, and worm screw 3 is connected with a joggle with worm gear 4.

Angular encoder 7 is affixed with base 2, and angular encoder 7 is provided with on the centre of gyration line of base 2, and centration axis 6 is coaxial affixed with panoramic table 5, and centration axis 6 is positioned on the centre of gyration line of panoramic table 5; Angular encoder 7 is connected with centration axis 6.
