Abstract

The invention belongs to the field of numerical control lathe fixtures, and particularly relates to a slender shaft numerical control lathe fixture. The slender shaft numerical control lathe fixture comprises a base, a sliding seat, a screw rod A, an arc-shaped support, a T-shaped guide block, a telescopic rod structure A and a telescopic rod mechanism B, wherein the sliding seat slides in a sliding groove A in the base in the direction perpendicular to the axial direction of a slender shaft; and the base is mounted on a lathe body. According to the slender shaft numerical control lathe fixture, the plurality of telescopic rod mechanisms A staggered at a certain angle wrap the slender shaft at a certain angle while effectively abutting against the slender shaft in the turning process, so that vibration caused by lower strength of the slender shaft in the rotating process is avoided, and the turning precision of the slender shaft is improved.

Description

technical field [0001] The invention belongs to the field of fixtures for numerically controlled lathes, in particular to a fixture for numerically controlled lathes with slender shafts. Background technique [0002] A shaft with a ratio of length to diameter greater than 25 (ie L / D>25) is called a slender shaft. Due to the poor rigidity of the slender shaft and the action and influence of cutting force, cutting heat and vibration during turning, it is easy to deform, and there are processing errors such as straightness and cylindricity, and it is difficult to achieve the shape and position accuracy and surface of the pattern. Quality and other technical requirements make cutting very difficult. The larger the L / d value, the more difficult the turning process. The rigidity of the slender shaft is poor. Due to the influence of many factors such as the machine tool and the cutting tool during the processing, the workpiece is prone to defects such as bending waist drum sha...
