Abstract

The invention belongs to the numerical control machine tool technical field and discloses a multi-sensor based numerical control machine tool heat dissipation electric cabinet control system. The system comprises a power source module, an instruction input module, a parameter initial module, a single-chip microcomputer control module, a heat dissipation module, a temperature compensation module, adisplay module, a fault detection module, a fault diagnosis module and an alarm module. According to the multi-sensor based numerical control machine tool heat dissipation electric cabinet control system of the invention, a movement amount is compensated through the temperature compensation module on the basis of deformation, so that a movement target value is generated and outputted, and therefore, the movement target value can be automatically modified according to temperature difference deformation, the improvement of the machining precision of a machine tool can be benefitted, and labor costs can be reduced. The multi-sensor based numerical control machine tool heat dissipation electric cabinet control system can be used for performing fault monitoring and diagnosis on a variety of numerical control machine tools with high diagnosis speed and accurate and reasonable diagnosis results realized, thereby reducing the failure time of the numerical control machine tools and improving the operating efficiency of the machining of the machine tools and the economic benefits of enterprises. The multi-sensor based numerical control machine tool heat dissipation electric cabinet controlsystem can be widely used in various numerical control machining fields.

Description

technical field [0001] The invention belongs to the technical field of numerical control machine tools, and in particular relates to a multi-sensor-based heat dissipation electrical cabinet control system for numerical control machine tools. Background technique [0002] CNC machine tool is the abbreviation of computer numerical control machine tools (Computernumericalcontrolmachinetools), which is an automatic machine tool equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the numerical control device through the information carrier. After calculation and processing, various control signals are sent by the numerical control device to control the movement of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. However, when the machine tool is running, there i...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the prior art are: when the machine tool is in operation, there is relative motion between the transmission parts, and the frictional heat of the machine tool screw, nut seat, bearing, etc. causes thermal expansion of the machine tool components, and the movement of each moving axis is related to that of the machine tool. The target is shifted, which causes the machining error of the machine tool; at the same time, the structure of the CNC machine tool is complex and expensive, and the operation of the machine tool is often accompanied by various faults, and the machine tool is often in an unattended state when the fault occurs. Therefore, "downtime loss" will be generated, which seriously restricts the effective utilization of CNC machine tools and causes a lot of economic losses.
