Abstract

The invention discloses a three-pin fork machining process. The machining process comprises the following steps that 1) an initially machined three-pin fork is transversely placed on a lathe, a positioning tool is arranged at one end, away from a handle part, of the three-pin fork, the positioning tool comprises a containing part with a containing cavity, wherein a transmission mechanism is arranged inside the containing cavity, a positioning rib is arranged on the inner wall of the containing cavity, the three-pin fork is inserted into the containing cavity of the containing part, and the position of the three-pin fork in the containing cavity is corrected through the positioning rib; 2) the three-pin fork is clamped from the circumferential surface of the handle part of the three-pin fork bu using a first central frame; 3) a cutter head of the lathe is provided with a a center drill tool, a center drill is equipped with the the center drill tool, and a center hole is drilled in the end surface by using the center drill; 4) a lathe center extends into the center hole and abuts against the three-pin fork, and the first center frame is loosened; 5) the positioning tool drives the three-pin fork to rotate around an axis, and a turning tool is used for turning the outer peripheral surface of the handle part of the three-pin fork; and 6) after the turning is completed, the lathe center returns to an original position. According to the three-pin fork machining process, the precision of the machined three-pin fork is high, and the consistency is good.

Description

Technical field [0001] The invention relates to the technical field of three-pin shaft fork processing, in particular to a three-pin shaft fork processing technology. Background technique [0002] The long-handled three-pin shaft fork is an important part of the semi-shaft of the drive shaft. It consists of a ball part with a ballway and a handle connected with the ball part. The traditional long-shank three-pin fork processing technology is completed by two equipments: a machine tool for milling the plane and drilling the center hole and a CNC lathe for turning the outer circle. The processing process includes the following steps: [0003] 1) Milling plane drilling center hole: End face milling and center hole drilling are performed on the machine tool by means of cavity clamping and shank V-block clamping. [0004] 2) Turning outer circle: The center hole and inner cavity processed by the plane milling and drilling center hole process are used as positioning, and the outer circle...
