A device and method for detecting the performance of a tool changing manipulator in a disk tool magazine

Abstract

The invention discloses a device and method for detecting the performance of a tool-changing mechanical arm of a disc-type tool changer, and belongs to the field of performance detection of function parts of a numerically-controlled machine tool. The method comprises the steps that the disc-type tool changer and a mechanical arm tool-changing system are disposed at the upper part of a substrate, and the disc-type tool changer is driven by a motor to convey a needed tool to a tool-changing position, and then a tool sleeve is electrically controlled to be turned, and a tool handle is stopped at the tool-changing position; meanwhile, the motor drives the tool-changing mechanical arm to operate, and the tool-changing mechanical arm is stopped at the tool-changing position; five laser displacement sensors which are disposed nearby the tool-changing position measure five position values when the tool handle and the mechanical arm reach the tool-changing position; an industrial personal computer calculates and obtains the horizontal position of the center of the tool handle, the horizontal position of the clamping center of the mechanical arm, and the vertical position of the bottom surface of the mechanical arm; the horizontal position of the center of the tool handle is compared with the horizontal position of the clamping center of the mechanical arm, and the coincidence degree of the two centers is determined. The method provides the experiment basis for the research of the reliability of the disc-type tool changer and the mechanical arm, and provides delivery detection for a disc-type tool changer producer.

Description

technical field [0001] The invention relates to a device and method for detecting the performance of a manipulator of a disc-type tool magazine, belonging to the field of detecting the performance of functional parts of a numerically controlled machine tool. Background technique [0002] The tool magazine and its automatic tool change system is a device that provides the required tool storage and tool change requirements in the automated machining process, and is the core component of the CNC machining center. Its automatic tool changing mechanism and tool storage function have changed the traditional human-based production mode, reduced non-cutting time, improved processing efficiency, and reduced production costs. The tool magazine is controlled by a computer program and can complete various processing requirements, such as drilling, milling, tapping, boring, etc. The tool magazine and manipulator perform many actions with high speed and require high positioning accuracy....
