Problems solved by technology

Its shortcoming is that because the test bench does not consider the arrangement and installation of corresponding detection sensors, it only tries to repeat the tool change process mechanically and repeatedly, and records the cumulative number of tool changes and the cumulative number of tool change failures. The collected data is single and cannot be obtained. Position accuracy, vibration, pressure, speed, torque and other detection data make it difficult to deeply analyze the cause of the fault, and then improve the reliability of the tool magazine manipulator in a targeted manner
In addition, the tool magazine and tool changing device used in this test bench are obviously different in structure from the application object of the present invention, the "disc tool magazine automatic tool changing system for turning and milling compound machining centers", and it does not have the spindle of a general machining center. Vertical and horizontal conversion function

Abstract

The invention discloses a disc tool magazine reliability testing device and method. The disc tool magazine reliability testing device comprises a supporting assembly, a sliding module, a simulation main shaft, a measuring module and an industrial personal computer. The supporting assembly comprises a base, an adjusting shim plate, a transverse beam, a bench and a support. The measuring assembly comprises a photoelectric proximity switch, a displacement sensor, an acceleration sensor, a vibration tester, a current clamp, a pressure transmitter and a noise monitoring system. After the sensors of the measuring assembly complete the parameter measurement of a disc tool magazine and a manipulator, signals are respectively transmitted to the industrial personal computer. By using the device and method, the actual working conditions can be simulated, the parameters can be comprehensively detected and a basis can be provided for the analysis, assessment and improvement of the running reliability of the disc tool magazine and the tool changing reliability of the manipulator.

Description

technical field [0001] The invention belongs to the reliability test technology of an automatic tool changing system of a disc tool magazine for a turning-milling compound machining center, in particular to a reliability test device and method for a disc tool magazine. Background technique [0002] The turning-milling compound machining center can significantly shorten the process chain of multi-process machining of high-precision and complex workpieces, and has been widely used in aviation, aerospace, shipbuilding, nuclear industry and some civil industries for small and medium batch, high-precision, complex-shaped rotary body processing. The automatic tool change system of the machining center is a device that provides tool change and storage requirements in the automatic processing process, including an automatic tool change mechanism (manipulator) and a tool magazine that can store multiple tools. The tool changing mechanism is used to perform the action of tool exchange...
