Pin wedge grafting type hole machining tool capable of being replaced in on-machine mode

Abstract

The invention discloses a pin wedge grafting type hole machining tool capable of being replaced in an on-machine mode. The pin wedge grafting type hole machining tool comprises a tool body part, a tool body cutting part and a pin body. The other end of the tool body part is provided with a cylindrical anti-bending shaft, a first groove and a first through hole penetrating in the radial direction. The other end of the tool body cutting part is provided with a cylindrical anti-bending hole, a first convex body and a second groove penetrating in the radial direction. When the other end of the tool body part is in butt joint with the other end of the tool body cutting part, the cylindrical anti-bending shaft and the first groove of the tool body part are matched with the cylindrical anti-bending hole and the first convex body of the tool body cutting part respectively, and the pin body is inserted into the first through hole of the tool body part and the second groove of the tool body cutting part at the same time. The pin wedge grafting type hole machining tool solves the problems that an existing hole machining tool is complex in disassembling process, low in replacing efficiency and the like, and the purposes of greatly improving tool installation efficiency and shortening production non-cutting time can be achieved on the basis that tool performance is not lowered.

Description

technical field [0001] The invention relates to the technical field of cutters, in particular to a pin-wedge-jointed hole-processing cutter that can be replaced on-machine. Background technique [0002] Hole processing tool refers to the tool used to process the inner surface of the part, that is, the inner hole. According to the difference in the relative connection between the hole and other parts, it can be divided into matching holes and non-fitting holes; according to its geometric characteristics, it can be divided into Through holes, blind holes, stepped holes, tapered holes, etc.; according to their different geometric shapes, they can be divided into round holes, non-round holes, etc. [0003] In the cutting process of the inner hole, in order to improve production efficiency, it is often required that the tool can be replaced on the machine. At present, different types of tools can be replaced on the machine through the tool magazine in the machining center, but t...
