Abstract

The invention discloses a tool-blocking tool-dropping fault early-warning device for a circular disc type manipulator tool magazine, and aims to carry out early-warning for tool-dropping and tool-blocking faults of an existing numerical-control machine circular disc type manipulator tool magazine. The tool-blocking tool-dropping fault early-warning device comprises two early-warning units, wherein each early-warning unit consists of a color mark sensor, a beam, an alarm and a bracket. The tool-blocking tool-dropping fault early-warning device for the circular disc type manipulator tool magazine disclosed by the invention can comprehensively detect that screw joint between a shank and a blind rivet loosens, can detect screw joint looseness with different degrees between the shank and the blind rivet according to the needs, is suitable for circular disc type manipulator tool magazines of different models, shows flexibility and universality, can automatically operate for a long time under an unmanned monitoring state, can reduce labor intensity, exposes and arouses product faults, provides practical essential data for reliability evaluation of the circular disc type manipulator tool magazine, and also can be used for screening chain-plate circular disc type manipulator tool magazines.

Description

technical field

[0001] The invention relates to a device for early warning of faults applied to a disc-type manipulator tool magazine on a numerically controlled machine tool. Early warning device. Background technique

[0002] CNC machine tools are the basis for improving the national manufacturing level and equipment level, and are an important symbol to measure a country's industrial development level and comprehensive national strength. As a device commonly equipped with CNC machine tools, the tool magazine system is a device that provides tool storage and tool change requirements in the automated machining process. It consists of a tool change mechanism and a tool magazine that can store multiple tools, changing the traditional The human-centered production method can complete various processing requirements through program control, such as milling, drilling, boring, tapping, etc., which greatly shortens the processing time and reduces production costs. The disc-type ...

Examples

Embodiment approach

[0069] 1. The model of the selected color mark sensor can be selected according to the difference of the disc manipulator tool magazine;

[0070] 2. Add some protection devices such as overcurrent and overload relays to the circuit of the alarm;
