Title:
ENERGY-SAVING AND HEAT-DISSIPATING CUTTING MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/243909
Kind Code:
A1
Abstract:
An energy-saving and heat-dissipating cutting machine, comprising a cutting machine body, the cutting machine body comprising a spindle (5), a spindle box (1), and a rotation driving device for driving the spindle (5) to rotate. The energy-saving and heat-dissipating cutting machine further comprises a driving device for driving a cooling liquid to flow, the driving device being provided in the spindle box (1) and being powered by the rotation driving device. In the technical solution, a pump (2) is provided in the spindle box (1), so that the pump (2) is prevented from being damaged by collision; in addition, the power input end of the pump (2) is connected to the rotation driving device, so that the rotation driving device can drive the rotation of the spindle (5) and the operation of the pump (2) at the same time, without requiring additional separate power supply to the pump (2), thereby having a better energy-saving effect, and reducing production costs. Moreover, providing the pump (2) in the spindle box (1) facilitates the arrangement of a liquid extraction pipe (22), and there is no need for the liquid extraction pipe (22) to penetrate the side wall of the spindle box (1), thereby avoiding leakage of the spindle box (1) from the side wall, and simplifying the structure of the spindle box (1).
