The invention discloses a cylinder sleeve boring tool. The cylinder sleeve boring tool comprises a tool rod body. The tool rod body comprises a tool rod. A tool handle and a tool bit are arranged at the two ends of the tool rod correspondingly. A rectangular groove, a positioning groove and a first positioning circular hole are formed in the upper surface of the tool bit, and a first installing groove is formed in the center of the rectangular groove. A gasket, a blade, a pressing plate and a pressing bolt are sequentially arranged in the rectangular groove, and a second installing groove is formed in the center of the gasket. The pressing plate comprises a pressing end and a fixing end, the pressing end is connected with a pressing positioning plate, the fixing end is provided with a second positioning circular hole, and the pressing bolt is sequentially matched with the second positioning circular hole and the first positioning circular hole. The pressing positioning plate is matchedwith the positioning groove. According to the cylinder sleeve boring tool, the tool bit weight is effectively reduced, the tool rod stability is improved, and vibration is reduced; and the length-diameter ratio of the tool rod is reduced, the scrap discharging effect during boring is improved, the workpiece cutting temperature is reduced, iron scrap and tool rod interference is prevented, the tool service life is prolonged, and the workpiece size stability is improved.
Description
technical field [0001] The invention belongs to the technical field of mechanical processing equipment, and relates to a cylinder liner boring tool. Background technique [0002] There are two major difficulties in machining the inner circle of the cylinder liner. 1) The tool bar is slender and easy to vibrate. Generally, the overhang length of the boring tool bar is L / diameter D<3 (that is, the ratio of length to diameter). When L / D>3, The tool bar is prone to vibration, which affects the surface quality and roughness of the inner circle of the workpiece, shortens the life of the tool, and even damages the equipment. In the actual application of cylinder liner processing, the length-to-diameter ratio can only reach 2.5. In order to process slender holes, it is usually necessary to use carbide to make the tool holder or use a complex vibration-damping tool holder, which is very costly; 2) High-speed boring It is not easy to remove chips: because the cylinder liner is ...
