Abstract

The invention discloses a miniature shaft roller driving mechanism, which comprises: a bracket; a driving motor, which is supported and arranged in the middle of the bracket; a first pulley, which is connected to the output end of the driving motor; two rotating mechanisms, It is arranged symmetrically, one end of the rotating mechanism passes through and is rotatably supported on the upper part of the bracket; two second pulleys are respectively matched and arranged at one end of the rotating mechanism; wherein, the first pulley , the centers of the two second pulleys are located in the same plane; the conveyor belt, which is arranged on the first pulley and the two second pulleys, drives the first pulley to rotate through the drive motor and then Drive the second pulley to rotate. The miniature shaft roller driving mechanism provided by the present invention overcomes the problems of large volume and low precision of the traditional tooling through the cooperation of the driving motor and the rotating mechanism. high.

Description

technical field [0001] The invention relates to a miniature shaft type roller drive mechanism, which belongs to the field of shaft rod correction. Background technique [0002] Miniature shaft workpieces do not have a center hole, and the cantilever drive is required to be based on one end of the outer circle of the workpiece during alignment and detection. At the same time, the rotation accuracy of the driving roller itself is required to be ≤0.003mm, and the repeated measurement accuracy is ≤0.005mm. Therefore, it is difficult for the roller mechanism of the conventional automatic straightening machine to complete the driving of such workpieces. Therefore, it is imperative to provide a high-precision cantilever outer-circle-driven roller drive device. Therefore, the present invention provides a roller drive mechanism capable of realizing miniature shafts to meet the alignment needs. [0003] The previous automatic straightening machine mainly needles the workpiece with a...
