Problems solved by technology
[0004] Although the cooling device in the above technology can have a certain cooling effect on the cutting tool, because the cooling liquid output pipe and the cold air output pipe in the device are arranged in a spiral shape from top to bottom, the cooling liquid or cold air first passes through the output pipe. When the remaining coolant or cold air flows into the bottom of the output pipe, with the reduction of coolant and cold air, the cooling liquid or cold air sprayed from the bottom of the output pipe at this time will not be effective due to the low pressure. At the same time, the temperature of the cutting tool increases gradually from top to bottom during work. At this time, although the coolant can flow to the bottom of the cutting tool after being sprayed from the top first, its cooling effect is gradually reduced in the process of the cooling liquid flowing downstream, thus greatly Reduced cooling effect and efficiency at the lowest end of the tool

The invention belongs to the technical field of cooling devices, and particularly relates to a turning-milling composite machine tool cutter cooling device. The device comprises a workbench, a main shaft and a cutter chuck, wherein a cutter is installed at the bottom end of the cutter chuck, a cooling sleeve is installed at the bottom end of the main shaft, a cooling cavity is formed in the cooling sleeve, the bottom end of the cooling sleeve is rotationally connected with a rotating ring, an annular boss and a positioning table are arranged on the upper end face of the rotating ring, an annular groove is formed in the bottom end of the cooling cavity, a through groove penetrating to the top face of the positioning table is formed in the top end of the rotating ring, a through type coolinggroove is formed in the rotating ring at the bottom end of the through groove in the radial direction of the rotating ring, and a spray head is connected to the side wall of the rotating ring corresponding to the end, away from the cutter, of the cooling groove. According to the device, by arranging an internal structure of the cooling device, cooling liquid or cold air can more effectively and efficiently cool all positions of the cutter, the using effect of the machine tool cutter is greatly improved, and the service life of the machine tool cutter is greatly prolonged.
Description
technical field [0001] The invention belongs to the technical field of cooling devices, in particular to a tool cooling device for turning and milling compound machine tools. Background technique [0002] When the tool is processing mechanical parts, it often needs to cool the tool and the mechanical parts through the coolant. At present, the coolant in the numerical control equipment mainly relies on the nozzle installed on the side of the tool and the mechanical part to spray the coolant. However, because the nozzle is set on the One side of the tool and mechanical parts cannot be well cooled to various parts of the tool and mechanical parts, resulting in inconsistent cooling levels, poor cooling effect, and in severe cases, shortening the service life of the tool. [0003] There are also some technical solutions for tool cooling devices in the prior art, such as a Chinese patent with a patent number of 2018219964290, which proposes a tool cooling device for machine tools,...
