Abstract

The invention discloses a reverse boring processing cutter device and a use method thereof for a hard sealing hole end surface. The device comprises a Morse cutter handle, a T-shaped integral reverse boring cutter and a pressing nut, wherein the middle of the Morse cutter handle is provided with a mounting hole, the T-shaped integral reverse boring cutter consists of a cutter bar and a cutter head, the pressing nut is vertically arranged at the side wall of the Morse cutter handle through threads, the end surface, facing the cutter bar, of the cutter head is provided with a main cutting blade, the outer circle surface of the cutter head is provided with an auxiliary cutting blade, the cutter bar is orthogonal with the pressing nut, the cutter bar is inserted into the cutter mounting hole, the section, inserted into the cutter mounting hole, of the cutter bar is provided with a rectangular groove, the middle of the rectangular groove is provided with a spherical groove, and the tail end of the pressing nut is provided with a spherical convex surface which is matched with the spherical concave surface. The device has the advantages that the strength of the cutter bar is effectively improved, and the breakage of the cutter bar is avoided; meanwhile, the precision is higher, the processing difficulty of roughness and position of the bottom end surface of a countersink hole is reduced, the rigidity, operability and economy of the cutter are improved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a countersinking tool device for hard sealing the end face of a hole and a use method thereof. Background technique [0002] In the field of mechanical processing, in processing such as figure 1 For the φD hole and its bottom surface on the workpiece shown, under normal circumstances, it is difficult to meet the surface roughness, flatness and φD hole diameter requirements of the workpiece when using the conventional countersinking tool device for changing blades. The locking position of the anti-sinking tool for changing the blade is at the bottom end of the tool bar, which is prone to slippage, resulting in machining misalignment or tool damage, which reduces the machining accuracy and easily leads to increased processing costs; and the traditional countersinking Countersinking tools are generally of a split design, that is, there is no fixed connection between t...
