Abstract
The utility model discloses an anticollision gearing for a numerically controlled machining center which comprises a frame, a bearing seat of a fixing end, a bearing seat of a supporting end, an anticollision device, a lead screw, a lead screw nut and a servo motor. The bearing seat of the fixing end, the bearing seat of the supporting end, the anticollision device, the lead screw, the lead screw nut and the servo motor are installed coaxially. The bearing seat of the fixing end and the bearing seat of the supporting end are fixedly arranged on the frame, and the lead screw is screwed on the lead screw. Two ends of the lead screw are arranged on the bearing seat of the fixing end and the bearing seat of the supporting end, and the anticollision device is arranged between the lead screw nut and the bearing seat of the fixing end. The servo motor is connected with the end closed to the bearing seat of the fixing end of the lead screw in a fixing mode. The anticollision gearing for the numerically controlled machining center can effectively reduce impact force, prolongs the service life of components like a bearing, the lead screw and a wire rail and the like, guarantees the accuracy of the components like the bearing, the lead screw and the wire rail and the like, and reduces maintenance cost.
