Description
TECHNICAL FIELD
[0001] The utility model relates to numerical control machine tool technical field especially, relates to a ventilation fan for numerical control machine tool. BACKGROUND
[0002] In the early development of numerical control machine tools, with the introduction of automation technology in the field of mechanical processing, the machine tool begins to integrate electronic control systems, motors and other key components. These electronic components will generate heat during operation, and if the heat cannot be dissipated in time, it will cause the component temperature to be too high, thereby affecting its performance and service life, and even may cause failure, resulting in problems such as decreased processing accuracy, production stagnation, etc. To solve this heat dissipation problem, people began to introduce ordinary industrial fans into numerical control machine tools. These fans are simple in structure, usually driven by a motor to rotate the fan blades, and through air flow to carry out the heat inside the machine tool, achieving basic heat dissipation function.
[0003] But as for the traditional equipment, the traditional ventilation fan structure is relatively simple, and the angle of the fan blade is usually fixed, which cannot flexibly adjust the air volume according to the actual heat dissipation needs of the numerical control machine tool. This leads to the fact that in some cases, the fan provides too much air volume, causing waste of energy; while in other cases, the air volume may be insufficient, which cannot effectively reduce the temperature inside the numerical control machine tool, affecting the normal operation and service life of the machine tool. After a long time of using the traditional fan, dust is easy to accumulate at the air outlet, because it lacks an effective cleaning structure. The accumulation of dust will gradually block the air outlet, increase the wind resistance, reduce the air outlet efficiency, and further weaken the heat dissipation effect. Moreover, when cleaning the air outlet, the traditional fan often needs to be disassembled manually for cleaning, which is tedious to operate, not only consumes a lot of time and manpower, but also may cause damage to the fan due to improper disassembly, which needs to be improved.
