Servo-drive numerical control rotating platform is the important composition parts of numerical control machining center, and the indexing accuracy of turntable and locking response speed are the important indicators that determines numerical control rotating platform performance; The indexing accuracy of turntable depends primarily on numerical control servo drive system, locking response speed depends on locking mode, and locking mode is varied, part numerical control rotating platform adopts hydraulic locking, its structure relative complex, piston movement speed is subject to the impact of hydraulic fluid flow rate, and response speed is slower, affect turntable locking positioning precision, and price is comparatively expensive.
Summary of the invention
The utility model provides gas-operated lock compact form servo-drive numerical control rotating platform, and it,, by multiple pneuma-lock brake locking turntables, locks fast response time, and positioning precision is high.
For this reason, the technical solution of the utility model is as follows: gas-operated lock compact form servo-drive numerical control rotating platform, formed by running part, lock portion, body, workbench, and workbench is supported on body by annular rolling guide;
Described running part, comprise servomotor, pinion, gear wheel, worm couple, central shaft, servomotor is fixed on body, pinion is connected with servomotor output shaft, gear wheel is connected with the worm screw of worm couple, the worm gear of worm couple is fixedly connected with workbench, and jackshaft is by bearings on body, and the center of workbench is fixedly connected with jackshaft;
It is characterized in that:
Described lock portion, comprise multiple pneuma-lock brakes, brake disc, described pneuma-lock brake, comprise upper shell, lower house, upper piston, lower piston, upper latch segment, lower latch segment, intermediate, upper shell, lower house are placed in respectively intermediate both sides, be bolted to connection, upper latch segment, lower latch segment are fixed by screws in respectively on upper piston, lower piston, upper piston, lower piston are placed in respectively the inner chamber of upper shell, lower house, form two cylinders, two cylinders are symmetrical along intermediate;
Multiple pneuma-lock brakes are by along the circumferential direction uniform being fixed on body of screw, and brake disc is ring-type, is fixed by screws in the lower end of worm gear, and brake disc is placed between latch segment, lower latch segment; In the time that compressed air enters cylinder from air inlet, promote piston and latch segment and move to brake disc, realize the locking to brake disc, because brake disc is fixedly connected with workbench, therefore workbench is locked immediately.
Such scheme is further limited and is, the quantity of pneuma-lock brake is four.
Beneficial effect: platform is made in the employing pneuma-lock brake work locking of the utility model innovation, not only lock fast response time, and positioning precision is high.
