Abstract

The invention discloses chamfering machining equipment and a chamfering machining method for curved surfaces of orifices of oil holes of connecting rods, and relates to the field of machining technologies for connecting rods of engines. The chamfering machining equipment comprises a horizontal three-coordinate driving mechanism, a servo spindle driving mechanism and an indexing worktable. The servo spindle driving mechanism is arranged on the horizontal three-coordinate driving mechanism and can be driven by the horizontal three-coordinate driving mechanism to move, a milling cutter shank is arranged at an end of the servo spindle driving mechanism, and a milling cutter is fixed onto the milling cutter shank. The chamfering machining equipment and the chamfering machining method for the curved surfaces of the orifices of the oil holes of the connecting rods have the advantages that the chamfering efficiency and the precision of the profile tolerance of the machined curved surfaces can be improved, and the chamfering consistency and the surface roughness can be enhanced.

Description

technical field [0001] The invention relates to the technical field of engine connecting rod processing, in particular to a device and method for chamfering curved surface of an oil hole orifice of a connecting rod of a diesel engine. Background technique [0002] The machining of holes and shafts must have the chamfering process of the shaft head and the orifice, especially the chamfering of the orifice, which has different technical requirements due to its different functions and functions. The orifice chamfering process is often considered as an auxiliary process and is ignored by process designers, resulting in the research on the chamfering process being stopped for a long time. In many machining factories, the fitter correction is used to replace the chamfering process. Due to the lack of attention to cutting tools and process methods, the processing efficiency is reduced or it is difficult to complete the processing content of the entire process. [0003] The diamet...
