Abstract

The invention provides a tulip machining technology. According to the technology, a ball channel inner cavity clamp, a center drill tool, a first center frame and a second center frame are used for primary clamping and positioning, one turning tool is adopted in the whole process for machining, tool change is not needed, the relative dimension of a machining position is effectively guaranteed, and corresponding errors caused by machine tool and tool change are avoided.

Description

technical field [0001] The invention relates to a processing technology for a three-pin shaft fork. Background technique [0002] The long handle three-pin fork (LONG TULIP) is an important part of the half shaft of the transmission shaft. It consists of two parts: the ball part 12 with the ball track 11 and the handle part 13 connected with the ball part 12, such as Figure 7 As shown, the fairway 11 is divided according to the joint type, which is divided into three major joint types and more than twenty kinds of small joint types. Different joint types combine with different handle shapes to form a variety of types of three-pin shaft forks. [0003] The traditional long-handled three-pin shaft fork processing technology is jointly 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. [0004] 1) Milling the plane and drilling the cent...
