A fast cooling cutting machine

Abstract

The invention discloses a cutting machine with rapid heat dissipation, which includes a main body of the cutting machine, and the main body of the cutting machine includes a main shaft box; wherein, the main shaft box includes a liquid storage chamber for storing cooling liquid, a first cooling chamber for cooling a bearing at one end of the main shaft, and a The bearing at the other end of the main shaft is cooled by the second cooling chamber. After adopting the above structure, the coolant in the liquid storage chamber can contact the main shaft to cool the main shaft. In addition, the first cooling cavity and the second cooling cavity are used for installing and fixing the bearing of the main shaft. The cooling liquid in the liquid storage chamber can be transported into the first cooling chamber and the second cooling chamber and contact with the bearing to absorb heat, so as to dissipate heat and reduce the temperature of the bearing. Finally, the cooling liquid in the first cooling chamber and the second cooling chamber flows back into the liquid storage chamber for collection. Compared with the prior art, the cooling liquid of the cutting machine of the present invention circulates in the headstock and contacts the main shaft and the bearing, which can quickly absorb heat and cool down the main shaft and the bearing, thus accelerating the cooling and heat dissipation of the cutting machine.

Description

technical field [0001] The invention relates to the field of cutting machines, in particular to a cutting machine with rapid heat dissipation. Background technique [0002] The cutting machine is mainly used for cutting and separating the plates during the machining process. Existing cutting machines are mainly provided with a rotatably connected main shaft in the main shaft box, on which a cutting saw blade is installed, and the main shaft is driven to rotate by a driving device, thereby driving the cutting saw blade to cut. During the cutting process, due to the high-speed rotation of the main shaft, the temperature of the main shaft and bearings will be too high, which will cause the main shaft and bearings to expand and affect the cutting accuracy. [0003] In order to solve the above-mentioned problem of excessively high temperature of the main shaft and bearings, most of the existing cutting machines open a cooling liquid flow groove on the side wall of the main shaft...

AI Technical Summary

Problems solved by technology

However, in the existing cooling method, since the coolant can only circulate in the spindle box and cannot directly contact the spindle and bearings, the heat absorption effect is poor, and it is impossible to quickly cool the spindle and bearings
