When number arriving, the upper hydraulic cylinder is stretched out, and the inclined-plane for positioning the cylindrical circumferential notch with rotating disk of bearing is combined, due to inertia
And inertia force is larger, upper hydraulic cylinder is fixed on swinging mounting, and swinging mounting starting can rotate an angle together with rotating disk,
But lower hydraulic cylinder, due to working under pressure, it can rotate to swinging mounting produces certain resistance, in this mistake
Cheng Zhong, upper hydraulic cylinder is also continuing toward overhanging, after hydraulic cylinder delay a period of time instantly, the operating pressure liter of lower hydraulic cylinder
Height, lower hydraulic cylinder is controlled back to stretch, after the two hydraulic cylinders all reach the stroke of design, the action of the detent mechanism group
Response is completed, and the control signal of other 3 detent mechanism groups is also identical, i.e. their action is also duplicate,
After this four sets of positioning groups respond in execution in the presence of control signal, the positioning of workbench is also just completed, workbench
Just it is parked in the position of setting.
Compared with prior art, Multi-station precision positioning table not only can be effective used by the utility model
Ensure positioning precision of the rotating disk in Switch of working position, and there can be suitable heavy load, the workbench of large rotating inertia, reliability
By force, production efficiency is high.The detent mechanism instead of tradition using stepper motor and use the pinpoint mode of servomotor, protect
On the premise of demonstrate,proving precision, equipment cost is significantly reduced.
