Fine-adjustment center water discharging eccentric boring cutter

Abstract

The invention relates to the field of machining, in particular to an improvement of a boring cutter head. A fine-adjustment center water discharging eccentric boring cutter comprises a blind rivet, a cutter handle and a boring head body which are installed in sequence. The center water discharging eccentric boring cutter further comprises a blade seat and an eccentric block. A through hole is formed in the center of the boring head body, the eccentric block is installed in the through hole of the boring head body, the hole diameter of the boring head body is slightly larger than the diameter of the eccentric block, and the eccentric block and the boring head body are connected together through a fine-adjustment mechanism and a fastening screw. The blade seat is installed on one side of the eccentric block. According to the fine-adjustment center water discharging eccentric boring cutter, the eccentric block is designed, an installation angle is adjusted through the eccentric block and the blade seat, a cutter rod is effectively prevented from touching a small boss in the machining process, and an inner hole and the outer cylindrical face of the small boss can be machined; by means of the design of the hole, cooling liquid can directly reach the cutting part through a channel in the cutter in the machining process; meanwhile, a balance block is designed, too large vibration is avoided, feeding can be finely adjusted, and operation is greatly facilitated; by means of the design of a threaded plug, machining of the hole is facilitated, and cooling liquid is prevented from flowing out.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to the improvement of a boring head. Background technique [0002] Boring tool is a kind of boring tool, the most commonly used occasions are hole processing, reaming, profiling and so on. A tool with one or two cutting sections designed to rough, semi-finish, or finish an existing hole. On the boring machine, when machining deep holes, there is a small boss in the middle of the hole. In order to prevent the head of the boring bar from touching the boss of the workpiece, it is necessary to design a boring tool that can be used in this case. Furthermore, the high-speed rotation of the boring head, the centrifugal force, and the imbalance of the boring head itself may cause large vibrations, which may damage the tool and the workpiece, so a balance weight needs to be designed. In order to facilitate the operation, it is necessary to design a fine-tuning feed mechanism. Content...
