Device and method for testing reliability of chain-type tool magazine and manipulator

Abstract

The invention discloses a device for testing the reliability of a chain-type tool magazine and a manipulator. The device comprises a base, the chain-type tool magazine, a tool, a hydraulic driving mechanism, the manipulator, a main shaft, a fixed frame, a test bed, a first displacement sensor, a triaxial acceleration sensor, a uniaxial acceleration sensor, a photoelectric proximity switch, a second displacement sensor, a first supporting frame, a second supporting frame and a third supporting frame, wherein the base is fixed on the ground; the chain-type tool magazine is fixedly arranged on the base; the tool is arranged at a tool position of the chain-type tool magazine, and is rotated by the chain-type tool magazine to reach a tool change position; the hydraulic driving mechanism is fixedly connected with the chain-type tool magazine; and the manipulator is arranged on the output shaft of the hydraulic driving mechanism, and is driven by the hydraulic driving mechanism to rotate, transversely translate and longitudinally translate so as to realize actions of tool catching, tool extraction, tool change and tool assemble. The device can test the reliability of the chain-type tool magazine and the manipulator, and has the advantages of convenience in operation and high practicability.

Description

technical field [0001] The invention belongs to the technical field of tool magazine and manipulator reliability test, in particular one. The invention relates to a test device and a method for carrying out reliability tests on a chain tool magazine and a manipulator, and real-time detection of motion parameters and states during a tool change process. Background technique [0002] The chain tool magazine and the manipulator are important components of the machining center. It is mainly composed of a chain tool magazine, a hydraulic drive mechanism and a manipulator. The specified machining tool can be selected in the tool magazine according to the operator's instructions, and the hydraulic drive mechanism The driving manipulator picks up the tool from the tool magazine and sends it to the main shaft of the machining center, and the main shaft of the machining center drives the tool to perform cutting operations. Due to the high degree of automation of the tool magazine and...

AI Technical Summary

Problems solved by technology

The shortcomings of the test bench are: 1. The tools used in the test bench are all simulated tools, which are quite different from the actual working conditions of the actual tool magazine and manipulator. On this basis, the analysis and research on its reliability results The results are not accurate enough; 2. There is no corresponding tool change process parameter detection system, which is limited to the discovery and recording of fault phenomena, and it is difficult to judge some accuracy changes, motion and mechanical factors related to faults
