Abstract

The invention discloses a rotation-prevention intermittent angle adjusting collet chuck which aims to achieve the automatic intermittent angle adjustment of a collet chuck and can prevent rotation. The collet chuck comprise a collet chuck body, a ratchet wheel is arranged on the collet chuck body in the circumferential direction, a push rod capable of pushing the ratchet wheel to rotate and a pawl enabling the ratchet wheel to be located are arranged on the ratchet wheel in the side direction, the bottom end of the pawl is hinged to a platform, the middle of the push rod is hinged to a disc face of a rotating disc, a long-strip-shaped hole is formed in the end, far away from the ratchet wheel, of the push rod, a base is arranged in the long-strip-shaped hole in the side direction, a guide pillar is arranged at the top end of the base, and the guide pillar and the long-strip-shaped hole are sleeved in a clearance mode to enable the push rod to have the axial freedom degree.

Description

technical field [0001] The invention relates to the processing technology of machine tool parts, in particular to an anti-rotation intermittent angle adjustment collet. Background technique [0002] Collets are widely used in the manufacturing and processing of machine tool parts. In the circumferential drilling process of the shaft workpiece, the angle of some drill bits is fixed, and the radial clamping angle of the shaft workpiece needs to be rotated to drill a circle around the shaft workpiece. This type of collet used for shaft workpieces often cannot automatically adjust the intermittent angle, and after turning to the specified angle, it will continue to rotate due to inertia, resulting in inaccurate positioning and troublesome drilling. Contents of the invention [0003] The invention provides an anti-rotation intermittent angle adjustment collet to realize automatic intermittent angle adjustment of the collet and prevent rotation. [0004] The anti-rotation in...
