Abstract

The invention discloses a base hole machining method of a radiator bracket. The method comprises the following steps: 1) firstly, a radiator bracket blank is taken; a semicylindrical projection arranged in the axial direction of a base hole is formed in the inner wall of the base hole of a base of the radiator bracket blank; on a solid structure integrated the semicylindrical projection with the inner wall of the base hole, a cylindrical hole arranged in the axial direction of the base hole is machined firstly with the circle center of the semicylindrical projection as circle center; and the cylindrical hole has a projection part projected on the inner wall surface of the base hole; and 2) the projection part of the cylindrical hole and the inner wall of a lap of the base hole connected with the projection part of the cylindrical hole are cut off; and a semicylindrical hole recessed in the inner wall of the base hole is obtained on the inner wall of the base hole of the radiator bracket. When the machining method performs the CNC machining, the cutter stress is uniform, the service life of a cutter is prolonged, the machining is easier, the subsequent machining of the radiator bracket is facilitated, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of radiator bracket manufacturing, in particular to a method for processing a base hole of a radiator bracket. Background technique [0002] The base of the radiator bracket is provided with a base hole, and the side wall of the base hole is provided with a semi-cylindrical hole arranged along the axial direction of the base hole, and the semi-cylindrical hole is recessed in the side wall of the base hole. After the die-casting of the radiator bracket, the semi-cylindrical hole is obtained through subsequent processing. The current traditional machining method of semi-cylindrical holes is to leave a machining allowance on the surface, but such a machining method will cause the tool to be damaged due to uneven force during CNC machining, reduce the service life of the tool, and make it difficult to process the product. Contents of the invention [0003] In order to solve the above technical problems, the o...
