Visual evaluation device and method for motion state of machine tool group component

Abstract

The invention relates to a visual evaluation device and method for the motion state of a machine tool group component. The device is composed of a control unit, an analog quantity collection card, a visual analysis unit, a driver unit, a group component installation unit, and a no-load motor installation unit. A to-be-evaluated group component is arranged on the group component installation unit, and driving motors of other movement group components of a machine tool are respectively mounted on the no-load motor installation unit. The control unit controls the idle running-in workpiece machining path of no-load driving motors of the to-be-evaluated group component and other movement group components of the machine tool through the driver unit, dynamic load data of the driving motor of the to-be-evaluated group component are extracted through the analog quantity collection card, the control unit processes the dynamic load data, and displaying and analyzing are conducted in the visual analysis unit in a chromatogram form. According to the visual evaluation device and method, offline independent evaluation and adjustment of the motion state of the machine tool group components are realized, adjustment is convenient, and the one-time success rate of mounting the group components on the machine tool is effectively ensured.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a visual evaluation device and method for the motion state of machine tool components. Background technique [0002] The overall basic motion state of the machine tool is determined by the motion state of each moving part of the machine tool. Conventional three-axis equipment is generally composed of Z-axis motion components (ie, head parts), X-axis motion components (ie, beam components), and Y-axis motion components ( That is, the motion state of the bed components) is determined by the motion state of the five-axis equipment. In addition to the above components, the five-axis equipment also includes four and five-axis components (ie, the turntable components). If the basic state of any component is not good, it will affect the state of the linkage, and ultimately affect the processing of the whole machine. Effect. At present, most of the state evaluation of...

[0002] The overall basic motion state of the machine tool is determined by the motion state of each moving part of the machine tool. Conventional three-axis equipment is generally composed of Z-axis motion components (ie, head parts), X-axis motion components (ie, beam components), and Y-axis motion components ( That is, the motion state of the bed parts) is determined by the motion state of the five-axis equipment. In addition to the above components, the five-axis equipment also includes four and five-axis components (ie, turntable components). If the basic state of any part is not good, it will affect the state of the linkage, and ultimately affect the processing of the whole machine. Effect

At present, most of the state evaluation of each group of components is to process the actual workpiece after assembling the whole machine, evaluate the motion state of the whole machine according to the processing effect, and then evaluate the basic motion state of the specific related moving parts through some detection methods. If it is necessary to adjust the group The mechanical state of the components is mostly operated in the online state of the whole machine or disassembled for offline adjustment. The operability is very poor, it is not convenient to adjust the mechanical state and affects the one-time success rate of the finished machine.
