Multiple groups of sliding columns 217 are slidably installed inside the limiting column 216, and multiple groups of first springs 218 are fixedly connected to the outer wall of the limiting column 216. One end of the first spring 218 is fixedly connected to the side wall of the tight sleeve 219, and the first spring 218 is located on the periphery of the sliding column 217.
[0019] Specifically, a cooling component 3 is installed on the milling cutter body 1, and the interior of the cooling component 3 includes a liquid inlet pipe 310, a liquid dispensing pipe 311, a liquid guide groove 312, a collecting groove 313, a pump 314, a liquid suction pipe 315, a liquid collecting box 316, 317 and a liquid spraying pipe 318. The liquid inlet pipe 310 is fixedly installed inside the connecting column 110, and the upper end of the liquid inlet pipe 310 is sleeved with the cooling box of the grinding equipment. A plurality of groups of liquid dispensing pipes 311 are fixedly connected to the outer wall of the liquid inlet pipe 310. The liquid dispensing pipe 311 is located inside the connecting column 110, and the lower end of the liquid inlet pipe 310 is fixedly connected to the upper end of the collecting groove 313. A group of electronic valves are installed at the connection between the collecting groove 313 and the liquid inlet pipe 310. One end of the liquid pipe 311 is fixedly connected to the side wall of the liquid guide groove 312. Specifically, a group of pumps 314 are fixedly installed on the upper inner end of the collecting groove 313. The liquid outlet of the pump 314 is fixedly connected to one end of the liquid spray pipe 318. The liquid spray pipe 318 is installed on the milling cutter body 1 and is located on one side of the liquid guide groove 312. A group of liquid suction pipes 315 are fixedly installed on the lower end of the pump 314. There is a gap between the liquid suction pipe 315 and the bottom of the collecting groove 313. Multiple groups of liquid inlet pipes 317 are installed in the side wall of the collecting groove 313. One end of the liquid inlet pipe 317 is fixedly connected to one side of the liquid collecting box 316. The liquid collecting box 316 is fixedly installed on the outer wall of the milling cutter body 1, and a group of filters are installed on the upper end of the liquid collecting box 316.
[0020] Specifically, a group of connecting columns 110 are fixedly installed on the upper end of the milling cutter body 1 , and a group of fixing cylinders 111 are fixedly installed on the upper end of the connecting columns 110 . The fixing cylinders 111 and the liquid inlet pipe 310 are fixedly connected.
[0021] (1) In the present invention, the plurality of limit blocks 213 are limited in position inside the mounting groove 212, and then the fixing tube 111 is inserted into the inside of the connecting tube 211, and then the fixing tube 111 is rotated. When the limit block 213 is rotated to the side of the window opened on the inner wall of the fixing tube 111, the return spring 214 will no longer be subjected to force, and it will drive the limit block 213 to rotate on the rotating shaft 215. At this time, the fixing tube 111 continues to be rotated. During the rotation process, the limit block 213 will slowly enter the compartment opened inside the fixing tube 111 through the window. After the limiting of the connecting tube 211 is completed, the plurality of connecting tubes 211 are screwed. Shaft 222, at this time, the connecting shaft 222 will drive the threaded rod 220 to rotate inside the fixed block 221, thereby pushing the limiting column 216 to move upward, and the limiting column 216 will drive the tightening sleeve 219 to enter the interior of the fixed cylinder 111 during the movement. When the limiting column 216 and the tightening sleeve 219 pass through the limiting block 213 and the upper end enters the upper layer of the connecting cylinder 211, stop rotating the connecting shaft 222 to complete the final limit. Compared with the traditional threaded connection, this connection method can prevent the connecting thread from wearing out, resulting in uneven grinding of the milling cutter, and can also quickly disassemble the milling cutter body 1.
[0022] (2) In the present invention, one end of the liquid inlet pipe 310 is connected to the pipe sleeve inside the cooling box. The cooling water inside the cooling box will flow into the multi-component liquid pipe 311 through the liquid inlet pipe 310, then enter the inside of the liquid guide groove 312, and then flow into the side wall gap of the milling cutter body 1. The cooling water will wash away the dust adhering to the inside of the side wall, and then flow downstream into the inside of the liquid collecting box 316. There is a screen on the upper layer of the liquid collecting box 316, which can filter the dust and small particles in the cooling water. The filtered cooling water will enter the inside of the collecting groove 313 through the liquid outlet pipe 317. When the cooling water flows through the side wall of the milling cutter body 1, it will take away a part of the heat of the milling cutter body 1, which has a cooling effect, thereby preventing the milling cutter body 1 from being too hot in hot weather and being unable to perform grinding work.
[0023] (3) In the present invention, one end of the liquid inlet pipe 310 is connected to the collecting groove 313, and a group of electronic valves are installed between them. When the cooling water in the liquid inlet pipe 310 flows into the liquid guide groove 312, a part of it will also enter the interior of the collecting groove 313. After the grinding work starts, the pump 314 is started, which will draw out the liquid in the collecting groove 313 and pour it into the interior of the multiple groups of liquid guide grooves 312, and then spray it on the side wall of the milling cutter body 1 to quickly cool it down.
[0024] Working principle: The staff first needs to manually limit the multiple groups of limit blocks 213 inside the installation groove 212, then insert the fixing cylinder 111 into the connecting cylinder 211, and then rotate the fixing cylinder 111. When the limit block 213 rotates to the side of the window opened on the inner wall of the fixing cylinder 111, the return spring 214 will no longer be under force, and it will drive the limit block 213 to rotate on the rotating shaft 215. At this time, the fixing cylinder 111 continues to be rotated. The limit block 213 will slowly enter the compartment opened inside the fixing cylinder 111 through the window during the rotation process. After the connection cylinder 211 is limited, the screw is tightened. The plurality of connecting shafts 222 are moved, and the connecting shafts 222 drive the threaded rods 220 to rotate inside the fixed block 221, thereby pushing the limiting column 216 to move upward. During the movement of the limiting column 216, the tightening sleeve 219 is driven to enter the interior of the fixed cylinder 111. When the limiting column 216 and the tightening sleeve 219 pass through the limiting block 213 and the upper ends enter the upper layer of the connecting cylinder 211, the connecting shaft 222 is stopped to complete the final limit. Compared with the traditional threaded connection, this connection method can prevent the connecting thread from being worn, resulting in uneven grinding of the milling cutter, and can also quickly disassemble the milling cutter body. 1. After the milling cutter body 1 is fixed, the liquid inlet pipe 310 enters the liquid outlet of the cooling box, and the cooling water inside the cooling box flows into the multi-component liquid pipe 311 through the liquid inlet pipe 310, and then enters the inside of the liquid guide groove 312, and then flows into the side wall gap of the milling cutter body 1. The cooling water will wash away the dust adhering to the inside of the side wall, and then flow downstream into the inside of the liquid collecting box 316. There is a screen on the upper layer of the liquid collecting box 316, which can filter the dust and small particles in the cooling water. The filtered cooling water will enter the inside of the collecting tank 313 through the liquid outlet pipe 317. The cooling water flows through the side wall of the milling cutter body 1. When the cooling water in the liquid inlet pipe 310 flows into the liquid guide groove 312, part of the cooling water will also flow into the collecting groove 313. After the grinding work starts, the pump 314 is started, which will draw out the liquid in the collecting groove 313, pour it into the multiple groups of liquid guide grooves 312, and then spray it on the side wall of the milling cutter body 1 to quickly cool it down.
