AI Technical Summary
Technical Problem
Existing technologies are inefficient, costly in terms of cutting tools, and involve cumbersome fixture setup processes when machining fisheye holes in fisheye rods, making it difficult to achieve rapid model changeover.
Method used
The design incorporates a special fixture and mother plate structure for the fisheye rod, combined with a rotary oil circuit distributor, to achieve rapid docking and concentric positioning between the fixture and the lathe spindle. The high-speed rotation of the lathe spindle is then used to cut the fisheye hole.
Benefits of technology
It improves the machining efficiency of fisheye rods, reduces tooling costs, simplifies the fixture changeover process, and avoids problems such as oil pipe entanglement and spindle interference.

Abstract
The application discloses a fish-eye rod fish-eye hole processing method and belongs to the technical field of machining. The fish-eye rod fish-eye hole processing method comprises the following steps: (1) designing a special fixture for the fish-eye rod; (2) designing a master disc structure, fixing the special fixture on the lathe main shaft through the master disc, and installing a rotary oil way distributor in the central cavity of the lathe main shaft; making the inlet and outlet oil ports of the clamping oil cylinder on the special fixture connected with the inlet and outlet oil ports on the oil way distributor shell through the oil channel built in the fixture and the master disc; (3) installing the lathe main shaft on a vertical numerical control lathe and connecting the oil way distributor with an external oil pressure station through an oil pipe; (4) placing the fish-eye rod on the special fixture and making the rotary center of the fish-eye hole of the fish-eye rod concentric with the rotary center of the fixture; and (5) starting the lathe, rotating the lathe main shaft at high speed, and cutting the fish-eye hole through a cutter. The fish-eye rod can be clamped and fixed and then placed on the lathe for machining, and the production efficiency is greatly improved; and the problems of cutter interference and oil pipe winding during rotary machining of the fixture can be solved.
