Abstract

The invention discloses a tool special for turning the excircle of a fork piece, which is characterized in that: a first nut is in threaded connection with a spindle; a spring is sleeved on the spindle; the excircle of the spindle is in clearance fit with an inner hole of a positioning sleeve; the excircle of the positioning sleeve is matched and welded with an inner hole of a V-shaped block; the excircle of a positioning block is in clearance fit with the inner hole of the V-shaped block; an inner hole of the positioning block is matched with the excircle of the spindle and is locked by a second nut; the V-shaped block is locked on a lathe spindle connecting disc through a bolt; the two lugs of a sliding fork are pressed against the V-shaped block; the inner space of the sliding fork is positioned by the positioning block; and a center sleeve is in taper fit with a center and is pressed against an inner hole of the sliding fork. Through the arrangement, the tool effectively prevents the fork piece from generating radial displacement under the action of extruding force when a cutter turns the fork piece, and ensures geometric tolerances such as the cylindricity of the machined excircle of the fork piece, the symmetry of the two opposite lugs, and the like.

Description

technical field [0001] The invention relates to a part processing tool, in particular to a special tool for the outer circle of fork parts, which belongs to the mechanical processing industry. Background technique [0002] The traditional machining of the outer circle of the fork parts of the drive shaft is only to position the two ears of the fork parts with the end surface of the outer circle, but not in the radial direction. Therefore, during the machining of the outer circle, the radial displacement of the fork parts under the extrusion force of the tool turning will cause an ellipse in the finished outer circle, and the cylindricity is out of tolerance (that is, the two ends of the outer circle are different in size), and the outer circle Problems such as excessive symmetry of the circle relative to the two ears. Some of the processed outer circles are positioned for subsequent processing, and some are directly welded to the shaft tube to assemble the drive shaft assem...
