[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] (1) The utility model provides a CNC lathe that is convenient for internal heat dissipation.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 A CNC lathe for facilitating internal heat dissipation comprises a lathe body 1, a heat dissipation mechanism 2 mounted on the side surface of the lathe body 1 and a dustproof mechanism 3 located inside the heat dissipation mechanism 2, a heat dissipation groove 11 and a mounting hole 12 are provided on the left surface of the lathe body 1, a motor 21 is installed on the rear surface of the heat dissipation mechanism 2, a negative pressure fan 22 is installed inside the heat dissipation mechanism 2, a disassembly groove 23 is provided on the upper surface of the heat dissipation mechanism 2, guide grooves 24 are provided on the two side surfaces inside the heat dissipation mechanism 2, a card groove 25 is provided on the bottom surface inside the heat dissipation mechanism 2, an exhaust groove 26 is provided on the upper end of the rear surface of the heat dissipation mechanism 2, a handle 31 is fixedly installed on the upper surface of the dustproof mechanism 3, guide blocks 32 are fixedly installed on the two side surfaces of the dustproof mechanism 3, and a lower surface of the dustproof mechanism 3 A clamping block 33 is fixedly installed, a filter hole 34 is opened on the surface of the dustproof mechanism 3, a filter screen 341 is installed inside the filter hole 34, and a chip collecting plate 35 is fixedly installed on the bottom surface of the dustproof mechanism 3. By driving the negative pressure fan 22, the hot air generated inside the lathe body 1 can be sucked into the interior of the heat dissipation mechanism 2 and discharged from the exhaust groove 26, thereby effectively preventing the interior of the lathe body 1 from being in a high temperature state and affecting the processing efficiency. By setting the filter hole 34 and the filter screen 341, it can be prevented that the dust and processing debris sucked in affect the effect of the negative pressure fan 22. At the same time, when the negative pressure fan 22 is turned off, the dust and debris sucked in will fall into the rear end of the chip collecting plate 35, and the dust and debris can be collected to a certain extent by the chip collecting plate 35 for subsequent centralized cleaning.

[0024] Furthermore, the size of the heat dissipation groove 11 is consistent with that of the heat dissipation mechanism 2. The two side surfaces of the heat dissipation mechanism 2 are fixedly connected with mounting plates 27. The surface of the mounting plate 27 is provided with screw holes 271. The screw holes 271 and the internal threads of the mounting holes 12 are connected with bolts 28. The heat dissipation mechanism 2 is fixedly connected with the side surface of the lathe body 1 through the mounting plates 27, the screw holes 271, the mounting holes 12 and the bolts 28. When in use, the heat dissipation mechanism 2 is placed opposite to the heat dissipation groove 11, such as Figure 2 As shown, the screw hole 271 on the surface of the mounting plate 27 is then fitted into the mounting hole 12 so that the two match, and the bolt 28 is threaded through the screw hole 271 and inserted into the interior of the mounting hole 12, so that the heat dissipation mechanism 2 can be fixed to the side surface of the lathe body 1, so that the heat dissipation mechanism 2 can subsequently dissipate the interior of the lathe body 1. When disassembling, the reverse operation can be performed.

[0025] Furthermore, the output end of the motor 21 penetrates into the interior of the heat dissipation mechanism 2 and is transmission-connected to the negative pressure fan 22, and the dust-proof mechanism 3 penetrates into the interior of the heat dissipation mechanism 2 through the disassembly and assembly slot 23. When in use, the negative pressure fan 22 is driven to rotate by the driving motor 21, so that the negative pressure fan 22 can generate suction. By setting the disassembly and assembly slot 23, the subsequent disassembly and assembly of the dust-proof mechanism 3 can be facilitated.

[0026] Furthermore, the guide block 32 is slidably connected to the guide groove 24, and the dustproof mechanism 3 is slidably connected to the inner surface of the dustproof mechanism 3 through the guide block 32 and the guide groove 24. After using the cooling system for a long time, due to the suction of the negative pressure fan 22, a large amount of dust and processing debris will accumulate at the filter hole 34 and the filter screen 341. At this time, the staff can hold the handle 31 and pull the dustproof mechanism 3 hard through the guide block 32 and the guide groove 24 to separate the card block 33 and the card groove 25, and the dustproof mechanism 3 can be pulled out of the interior of the cooling mechanism 2 through the disassembly and assembly groove 23. At this time, the filter hole 34 and the filter screen 341 can be cleaned to prevent dust and debris from affecting the cooling effect.

[0027] Furthermore, the block 33 is engaged with the slot 25, and the dustproof mechanism 3 is fixed to the inner bottom surface of the dustproof mechanism 3 through the block 33 and the slot 25. When in use, the dustproof mechanism 3 can be made more stable inside the heat dissipation mechanism 2 by setting the block 33 and the slot 25.

[0028] Working principle: The utility model is a CNC lathe that is convenient for internal heat dissipation. When in use, the heat dissipation mechanism 2 can be installed on the side surface of the lathe body 1 through the mounting hole 12, the screw hole 271, the bolt 28 and the mounting plate 27. The interior of the lathe body 1 can be communicated with the interior of the heat dissipation mechanism 2 through the heat dissipation groove 11. When the lathe body 1 is processed for a long time and the internal temperature is too high, the motor 21 can be driven. The motor 21 drives the negative pressure fan 22 to rotate, and the hot air generated inside the lathe body 1 can be sucked into the interior of the heat dissipation mechanism 2, and then discharged from the exhaust groove 26. This can effectively prevent the internal temperature of the lathe body 1 from being too high, thereby affecting the processing efficiency. At the same time, in order to ensure that the effect of the negative pressure fan 22 is not affected by dust and processing debris , the filter holes 34 and the filter screen 341 can block dust and processing debris. When the negative pressure fan 22 is turned off, the dust and debris will fall to the rear end of the chip collecting plate 35, thereby collecting the dust and debris to a certain extent, so as to facilitate subsequent centralized cleaning. After using the cooling system for a long time, due to the suction force of the negative pressure fan 22, a large amount of dust and processing debris will accumulate in the filter holes 34, the filter screen 341 and the rear end of the chip collecting plate 35. In order to clean them in a centralized manner, the staff can use the handle 31 to pull the dustproof mechanism 3 out of the cooling mechanism 2, and then clean the filter holes 34 and the filter screen 341 as well as the collected dust and debris, so as to ensure that the cooling effect is not affected, thereby increasing the overall practicality.
