Abstract

The invention discloses a PCD combined cutter for machining an automobile steering device. The PCD combined cutter comprises a cutter body and a cutter handle. The cutter body is arranged at the left end of the cutter handle, four cutting parts are arranged on the cutter body in sequence from the left end to the right end, the four cutting parts are connected in a stepped mode and are cylinders, the diameters of the four cutting parts are sequentially increased, and two or more cutting blades are arranged on each cutting part along the circumferential ring. The first cutting part is arranged at the front end of the cutter body, the first blades extend from the left end face of the first cutting part to the rear half section of the first cutting part, and the shapes of the first blades are same and continuous waveform sawteeth. The second blades in the second cutting part are arranged at the outer edge corner of the left end face of the second cutting part, and the second cutting part and the third cutting part are connected through an inclined plane. The third blades extend from the rear end of the second cutting part to the front end of the third cutting part. The fourth blades are arranged at the joint of the third cutting part and the fourth cutting part, the joint is formed by two inclined planes with different angles, the fourth blades extend from the rear end of the third cutting part to the front end of the fourth cutting part, and the shapes of the fourth blades are consistent with the shape of the joint.

Description

technical field [0001] The invention belongs to the field of mechanical processing cutters, in particular to a PCD composite cutter for processing automobile steering gears. Background technique [0002] Automobile steering gear parts are complex in structure and irregular in shape, requiring many parts to be processed and difficult. On the same processing surface, different processing parts may require multiple operations such as milling, drilling, reaming, reaming, and chamfering. If a single-function tool is used to process it, multiple operations are required. The precision of the finished workpiece is very low and cannot meet the assembly requirements due to the error in positioning due to multiple tool changes. During the process, milling, reaming, drilling and other processes are completed at the same time, which has many advantages such as high processing efficiency, high stability and high product precision. Contents of the invention [0003] Aiming at the situa...
