Abstract

The invention discloses a lathe clamping tool suitable for special-shaped slender shaft parts. The clamping inner sleeve is formed with a through hole for inserting the special-shaped slender shaft part; the through hole penetrates the clamping inner sleeve along the rotation axis; In the direction of the axis of rotation, the two ends of the clamping inner sleeve are respectively formed with a first clamping claw and a second clamping claw for clamping special-shaped slender shaft parts; the outer periphery of the first clamping claw is formed with a first clamping slope; The outer periphery of the second clamping jaw is formed with a second clamping slope; the end of the clamping sleeve away from the driven pull rod is formed with a first force application slope that matches the first clamping slope; one end of the bottom positioning sleeve is in contact with the turning body of the lathe Contact; the bottom positioning sleeve is formed with a second force-applying inclined surface that matches the second clamping slope. The bottom positioning sleeve is sleeved on the outer periphery of the clamping inner sleeve; the clamping outer sleeve is sleeved on the outer circumference of the bottom positioning sleeve. The lathe clamping tool suitable for special-shaped slender shaft parts disclosed by the invention can realize automatic clamping and has high clamping stability.

Description

technical field [0001] The invention relates to a lathe clamping tool suitable for special-shaped slender shaft parts. Background technique [0002] The clamping mechanism usually used in traditional CNC lathe parts is a three-jaw clamping mechanism. The lathe pull rod of the lathe drives the three-jaw clamping mechanism to clamp the parts. [0003] When the traditional CNC lathe clamps the slender shaft parts, it is easy to cause the bending of the shaft parts and the clamping is unstable. Contents of the invention [0004] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a lathe clamping tool suitable for special-shaped slender shaft parts, which can realize automatic clamping and has high clamping stability. [0005] A lathe clamping tool suitable for special-shaped slender shaft parts, which is characterized in that it includes: a lathe connecting plate, a lathe rotary body defining a rotary axis, a lathe pull pl...
