Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0024] Such as figure 1 and figure 2 As shown, the detection device includes a disc tool magazine body 1, an indexing turntable 2, a tool holder 3, a bearing 4, a bearing end cover 5, a connecting shaft 6, a turntable shaft 7, an encoder 8, a fixing plate 9, and a signal acquisition card 10 and PC 11. The tool magazine body 1 is fixed on the tool magazine base, so the body is fixed, the indexing turntable 2 is connected with the tool magazine body 1 through the bearing 4, and the inner ring of the bearing 4 is interference fit with the fixed shaft on the tool magazine body 1 , the outer ring is in interference fit with the intermediate shaft hole of the indexing turntable 2, and the tool pocket 3 is installed on the indexing turntable 2, so that, through the rotation of the indexing turntable 2, the tool pocket 3 where the tool required for the next process is ...

Abstract

The invention relates to a device and method for detecting indexing accuracy of a rotary disc in a disc tool changer and belongs to the field of performance detection of functional components of numerically-controlled machine tools. By analyzing the mechanical structure of the disc tool changer, a rotary disc shaft and a connecting shaft are designed for installing and fixing an encoder; and an inner ring of the encoder rotates by a circle, and a fixed number of square-wave signals are send out and collected through a data collecting card. A digital control system is operated to control action of the tool changer, so that after an appointed tool arrives in a tool changing position, the encoder detects the deviation angle of the center of a tool sleeve where the tool is located relative to the centerline. Collected data are analyzed, stored, processed and displayed on a computer. The problem that the indexing accuracy of the rotary disc in the disc tool changer is hard to detect is solved, and certain experimental data are provided for tool changer manufacturing enterprises.

Description

technical field [0001] The invention relates to a device and method for detecting the indexing accuracy of a turntable in a disk-type tool magazine, and belongs to the field of performance detection of functional components of a numerical control machine tool. Background technique [0002] The tool magazine and automatic tool change device are important components of the CNC machining center, and are key functional components with the functions of reserve machining center tools and automatic tool change, including the tool magazine and the manipulator. The tool change process of the tool magazine and automatic tool changer is mainly divided into two parts: tool selection and tool change: the tool magazine accurately sends the tool holder where the required tool is located to the tool change position according to the instructions issued by the control system; the automatic tool changer will The desired tool is exchanged with the tool on the spindle. There are many types of t...
