A device and method for testing tool flipping positioning accuracy in a tool magazine

Abstract

The invention discloses a device and a method for testing tool turnover location accuracy in a tool magazine, and belongs to the field of numerically-controlled machine tools. The device comprises a chain type tool magazine automatic tool changing device, a laser displacement sensor A, a laser displacement sensor B, a tool, an installation platform, a control cabinet, a virtual main shaft, a data acquisition card, and a personal computer (PC) machine. The chain type tool magazine automatic tool changing device is installed on the installation platform, the laser displacement sensor A and the laser displacement sensor B are fixed on a body of the chain type tool magazine, the control cabinet is used for sending the tool to a tool changing position in a chain type transmission mode, and turnover of the tool from the horizontal state to the vertical state is finished under air cylinder effect. At the moment of finishing turnover of the tool, laser displacement sensors can detect a tool handle position and offset distance value of the laser displacement sensors fixed on the body. The tool turnover location accuracy can be obtained by inputting displacement parameters into the PC machine through the data acquisition card. The device and the method solve the problem that the tool turnover location accuracy is difficult to test when the tool magazine is in an operating state.

Description

technical field [0001] The invention relates to a device and a method for testing the positioning accuracy of tool turning in a tool magazine, and belongs to the field of numerically controlled machine tools. Background technique [0002] During the use of the tool magazine and automatic tool changer, due to unexpected reasons such as collisions and loose positioning fasteners, the position accuracy of the tool after turning over changes; while the mutual position accuracy of the tool, manipulator, and spindle is directly It affects the accuracy and reliability of the automatic tool change of the machine tool; therefore, it is very necessary to detect the positioning accuracy of the tool turning. [0003] Since there are many influencing factors, and the degree of influence of each factor cannot be directly determined, the positioning accuracy of tool turning can only be tested based on experiments. [0004] In order to systematically study the change of the positioning acc...

[0003] Since there are many influencing factors, and the degree of influence of each factor cannot be directly determined, the positioning accuracy of tool turning can only be tested based on experiments.

[0004] In order to systematically study the change of the positioning accuracy of the tool turning during the operation of the tool magazine and the automatic tool changer, and to grasp the law of its accuracy change, a complete set of devices and methods for testing the positioning accuracy of the tool turning are needed, but currently there is no There is no device about the positioning accuracy of the tool turning
