[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] See also Figure 1-6 The utility model provides a technical solution: a spindle sleeve of a CNC engraving machine, comprising a base plate 1, a clamping and fixing component 2 is arranged on the surface of the base plate 1, the clamping and fixing component 2 comprises a screw groove 201 and a bidirectional screw 202, the screw groove 201 is opened inside the base plate 1, a bidirectional screw 202 is arranged inside the screw groove 201, a bearing 203 is arranged at one end of the bidirectional screw 202, a handle 204 is arranged at the other end of the bidirectional screw 202, a moving block 205 is arranged on the surface of the bidirectional screw 202, a threaded hole 206 is opened at the bottom of the moving block 205, a supporting block 207 is arranged at the top of the moving block 205, a clamp 208 is connected to the top of the supporting block 207, a slot 209 is opened at the top of the clamp 208, a threaded rod 210 is inserted into the slot 209, and a nut 211 is arranged on the surface of the threaded rod 210.

[0019] like Figure 1-6 As shown, the bidirectional screw 202 is fixedly connected to the handle 204, and the bidirectional screw 202 is rotationally connected to the bearing 203 via the screw groove 201. When the handle 204 is rotated, the bidirectional screw 202 can be driven to rotate in the screw groove 201, and the bearing 203 can ensure that the bidirectional screw 202 can rotate more stably.

[0020] The moving block 205 is threadedly connected to the bidirectional screw 202 through the threaded hole 206, and the support block 207 is fixedly connected to the clamp 208. When the bidirectional screw 202 rotates, it can simultaneously rotate with the two groups of moving blocks 205 through the threaded hole 206, so that the moving block 205 can push the support block 207 and the clamp 208 to clamp and fix the main shaft.

[0021] like Figure 1-6 As shown, the threaded rod 210 passes through the slot hole 209 and forms a threaded connection with the nut 211. After the two sets of clamps 208 clamp and fix the main shaft, the threaded rod 210 can be passed through the slot hole 209 and then threadedly fixed with the nut 211, thereby improving the firmness of the main shaft after installation.

[0022] like Figure 1-6 As shown, a heat dissipation component 3 is provided at the bottom of the base plate 1, and the heat dissipation component 3 includes a slot 301 and a block 302. The slot 301 is opened at the bottom center of the base plate 1, and the top of the block 302 is set inside the slot 301. A fan 303 is provided on one side of the block 302. When the tool is used to carve objects for a long time, a large amount of heat can be generated on the surface. At this time, the fan 303 can be turned on to dissipate the heat of the tool to increase its service life.

[0023] A threaded groove 304 is provided on the other side of the block 302 , and a notch 305 is provided on one side of the base plate 1 close to the slot 301 . A bolt 306 is inserted into the notch 305 . The notch 305 allows the top of the block 302 to be easily inserted, thereby fixing the fan 303 .

[0024] like Figure 1-6 As shown, the position and size of the bolt 306 match the position and size of the thread groove 304 and the notch 305. After the bolt 306 passes through the notch 305, a threaded connection is formed between the bolt 306 and the thread groove 304. When the top of the block 302 is inserted into the notch 305, the bolt 306 can be passed through the notch 305 and threadedly connected and fixed with the thread groove 304, thereby achieving the installation and fixation of the fan 303.

[0025] The use method and working principle of the device: When the main shaft needs to be clamped and fixed, the main shaft can be placed between the two sets of clamps 208, and then the handle 204 can be turned forward, so that the handle 204 can drive the bidirectional screw 202 to rotate forward in the screw groove 201, and the bearing 203 can make the bidirectional screw 202 rotate more stably in the screw groove 201. When the bidirectional screw 202 rotates forward, it will also be threaded with the two sets of moving blocks 205 through the threaded hole 206 at the same time. The two groups of moving blocks 205 simultaneously push the supporting block 207 to move inwards, and while the supporting block 207 moves, it also pushes the clamp 208 to clamp the spindle. When the clamp 208 clamps the spindle firmly, the handle 204 can be stopped from rotating. At this time, the threaded rod 210 is passed through the slot 209 and is threadedly connected and fixed with the nut 211, and the three groups at the top of the clamp 208 are all fixed. In this way, the fixed installation of the spindle is completed. When the spindle needs to be disassembled, When removing the spindle, first remove all three sets of nuts 211, and pull all three sets of threaded rods 210 out of the slots 209, then reversely rotate the handle 204 to drive the bidirectional screw 202 to reverse, so that the moving block 205 drives the moving block 205 and the two sets of clamps 208 to move to both sides at the same time, and then remove the spindle, thereby completing the disassembly of the spindle, improving the stability of the spindle when working, and avoiding the problem of low precision during engraving caused by the spring fixing the spindle. When engraving, the fan 303 can be turned on to dissipate the heat of the file. When the fan 303 needs to be disassembled, the bolt 306 can be rotated in the opposite direction and taken out from the thread groove 304 and the notch 305, and then the block 302 can be pulled out from the slot 301 to complete the disassembly. When the fan 303 needs to be installed, the block 302 can be inserted into the slot 301, and the bolt 306 can be passed through the notch 305 and then threadedly connected to the thread groove 304 to avoid high-temperature thermal deformation and reduced tool life.
