Abstract
The invention discloses a feeding mechanism of a numerical control machine. The feeding mechanism is characterized by comprising a feeding table and a pulling and clamping device which is arranged on the feeding table and can clamp a blank bar material, wherein a bearing is arranged on the feeding table; and a bushing in clearance fit with the blank bar material is arranged in the bearing. In the feeding mechanism, the bearing is arranged on the feeding table and the bushing in clearance fit with the blank bar material is arranged in the bearing. During processing, the blank bar material is penetrated into the bushing and one end of the blank bar material is clamped by a jaw chuck. Because the clearance between the blank bar material and the bushing is very small, the deflection of the blank bar material is too small to influence the processing. In addition, the device does need a feeding rod and a feeding pipe, so that noise generated by collision between the feeding rod and the feeding pipe in an ordinary feeding mechanism is avoided.
