Abstract
The present invention discloses a radial feeding groove boring cutter. Cutting tools are arranged on a main shaft of a machine tool. The main shaft rotates at a proper rotary speed and feeds. When a positioning sleeve is in contact with the end face of a workpiece, the positioning sleeve and a sliding sleeve stop rotating and moving forwards. By a plane bearing, a backing pin and sleeves, a cutting bar only rotates and does not advance. When a cutter body moves on, angled holes of the cutter body and the cutting bar begin to move, so the radial feeding of a cutter bit is forced to realize the working of groove boring. The dimension of a groove to the end face of the work piece can be controlled by adjusting the position of the positioning sleeve on the sliding sleeve. The inside diameter of the groove can be controlled by adjusting the position of an adjusting nut on the cutter body. When the groove boring finishes, a boring bar falls back, and the cutter bar is reset under the action of a spring and a guide pillar. The present invention has the function of radial feeding, so the groove boring operation is convenient and easy; with the function of dimension control, the present invention effectively ensures the processing quality, and is suitable for the mass production of workpieces.
