Medium circulation heat dissipation milling system based on intelligent switching of internal cooling and external cooling

Abstract

The invention relates to a medium circulation heat dissipation milling system based on intelligent switching of internal cooling and external cooling. The system comprises a workbench, a main shaft connected with a power system, a fixing ring which sleeves the periphery of the main shaft, can rotate relative to the main shaft and is provided with a medium inlet and a medium outlet, and a cutter assembly connected with the main shaft. A storage cavity is formed in the cutter assembly, the storage cavity is communicated with one end of a first flow channel and one end of a second flow channel, the other end of the first flow channel and the other end of the second flow channel are communicated with a through hole formed in the main shaft, a heat collection hole communicated with the storage cavity is further formed, is a blind hole and extends to a blade of the cutter assembly, the first flow channel and the second flow channel are configured in the mode that under relative rotation of the fixing ring and the main shaft, the first flow channel is communicated with the medium inlet, the second flow channel is communicated with the medium outlet simultaneously, the second flow channel is communicated with the medium inlet simultaneously, the first flow channel is communicated with the medium outlet, the transformation cost of the milling system is low, and intelligent switching of cooling modes can be achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a medium circulation heat dissipation milling processing system based on intelligent switching of internal and external cooling. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In the existing processing equipment where the tool is the main movement, such as a milling device, in order to remove heat from the tool and the workpiece, cutting fluid must be used to cool the processing area. Improper cooling can reduce machining quality and tool life. The cooling effect of the cutting fluid is to take the cutting heat away from the tool and the workpiece through the convection and vaporization between it and the tool, chips and workpiece that are heated due to cutting, thereby effectively reducing the cutting temperature and reducing...

AI Technical Summary

Problems solved by technology

The inventors found that, compared with the cooling and lubrication method of internal cooling, this cooling and lubrication method cannot meet the cooling and lubrication requirements of machining conditions such as holes and grooves with a large milling depth.

[0005] At present, in the actual processing process, for machine tools that can support multiple cooling methods, the operator often needs to judge which cooling method is required for the processing condition according to his own experience to switch the mode, which has great limitations and is easy to Misjudgment caused the cutting zone to fail to dissipate heat effectively, failing to achieve intelligent switching of cooling methods, and wasting a lot of human resources
