Abstract

A tool magazine reliability test bench tool change position adaptive centering adjustment device and method belong to the mechanical adaptive adjusting field, and aim to solve the problems of low adjusting precision and complex operation and the time-consuming and labor-consuming problems in the prior art. The device comprises a measurement taper shank, an automatic mechanical detection device and a main-shaft bottom feeding unit; and a drive gear and a driven gear in the automatic mechanical detection device are integrally disposed in a tool-grabbing disc, a servo motor A drives the drive gear to rotate, a positioning adjusting rod is connected with the lower end face of a driven gear shaft through an adjusting screw, a measuring rod is connected with the upper part of the positioning adjusting rod through a positioning pin, the positioning pin is located on the axis of the driven gear shaft, a force sensor is fixed to the lower part of the positioning adjusting rod, and the force sensor is connected to the lower part of the measuring rod through a connecting spring. The measurement taper shank is coaxially installed on a mechanical main shaft, the tool-grabbing disc of the automatic mechanical detection device is clamped through a manipulator, and a control unit of a tool magazine reliability test bench controls a motion of the main-shaft bottom feeding unit according to a signal acquired by the force sensor.

Description

technical field [0001] The invention belongs to the technical field of mechanical self-adaptive adjustment, and in particular relates to a device and method for self-adaptive centering adjustment of a tool change position on a tool magazine reliability test bench. Background technique [0002] At present, domestic CNC machine tools have made great progress in compound machining, speed and precision, but there is still a big gap between their reliability and the international level, and the reliability of key functional components has become one of the standards for measuring the performance of CNC machine tools One, therefore, research on the reliability of key functional components has become a top priority. Relying on a strong scientific research platform, the CNC Machine Tool Reliability Laboratory of Jilin University, based on long-term on-site reliability test research, concluded that the high failure rate of key functional components such as tool magazine manipulators ...
