Cooling and heat dissipation monitoring and alarming system of large numerical control machine tool

Abstract

The invention discloses a cooling and heat dissipation monitoring and alarming system of a large numerical control machine tool, relates to the technical field of cooling and heat dissipation detection, and solves the technical problem that in the prior art, the temperature of machine tool equipment cannot be monitored, so that the working efficiency is reduced. The temperature data of the machinetool equipment is analyzed through a temperature monitoring unit, thus, the machine tool equipment is monitored, and the average temperature of the machine tool equipment, the maximum temperature difference of the machine tool equipment during working and non-working time, and the temperature change speed when the machine tool equipment works are obtained; the temperature coefficient Xi is obtained through a formula; if the temperature coefficient Xi of the machine tool equipment is smaller than a temperature coefficient threshold value, the abnormal temperature of the machine tool equipmentis determined, and a temperature abnormal signal is generated, and is sent to a cloud management platform; and temperature monitoring is performed on the machine tool equipment, so that reduction of work efficiency caused by faults of the machine tool equipment during work can be prevented, and the fault probability of the machine tool equipment can be reduced.

Description

technical field [0001] The invention relates to the technical field of cooling and heat dissipation detection, in particular to a cooling and heat dissipation monitoring and alarm system of a large numerically controlled machine tool. Background technique [0002] The machine tool is affected by the temperature change of the workshop environment, the heating of the motor and the friction of the mechanical movement, the cutting heat and the influence of the cooling medium, resulting in uneven temperature rise of each part of the machine tool, resulting in changes in the shape accuracy and machining accuracy of the machine tool. The temperature rise will cause the temperature of each part to change with time, which will cause the machine tool to lose the existing adjustment accuracy, thereby affecting the size of the workpiece to be processed. At the same time, the temperature rise will also change the bearing clearance, thereby affecting the machining accuracy. On the other h...

Problems solved by technology

The temperature rise will cause the temperature of each part to change with time, which will cause the machine tool to lose the existing adjustment accuracy, thus affecting the size of the workpiece to be processed. At the same time, the temperature rise will also change the bearing clearance, thereby affecting the machining accuracy.

On the other hand, the increase in temperature makes the temperature distribution uneven, causing changes in the mutual positional relationship between parts or parts, resulting in displacement or distortion of parts

[0003] However, in the existing technology, it is impossible to monitor the temperature of the machine tool equipment, resulting in a decrease in work efficiency. At the same time, it is impossible to monitor the heat dissipation performance of the machine tool equipment, which increases the risk of equipment performance degradation due to slow heat dissipation of the machine tool equipment.
