A motor 45 is fixedly connected to the inside of the heat dissipation box 41. One end of the output shaft of the motor 45 is fixedly connected to a heat exhaust fan 46. The heat exhaust fan 46 is arranged inside the heat exhaust chamber 42. The other end of the output shaft of the motor 45 is fixedly connected to a guide fan 47. The guide fan 47 is arranged inside the cooling chamber 43. A heat conducting copper plate 48 is fixedly connected to the inside of the heat dissipation box 41. A refrigeration sheet 49 is fixedly connected to the middle of the heat dissipation box 41. One end of the heat conducting copper plate 48 extends into the heat exhaust chamber 42. The other end of the heat conducting copper plate 48 extends into the cooling chamber 43. One end of the refrigeration sheet 49 extends into the heat exhaust chamber 42.

[0039] Embodiment 2

[0040] As Figures 1-6 shown, on the basis of Embodiment 1, the present invention provides a technical solution: Preferably, the dust-proof net 44 includes a net plate 441. The net plate 441 is fixedly connected to the side of the heat dissipation box 41. A connecting rod 442 is movably connected to the middle of the net plate 441. The connecting rod 442 is fixedly connected to the top of the exhaust fan 46. A dust cleaning brush 443 is fixedly connected to the top side of the connecting rod 442.

[0041] In this embodiment, through the setting of the dust-proof net 44, dust can be prevented from entering the inside of the heat dissipation box 41. At the same time, the rotation of the exhaust fan 46 can also drive the connecting rod 442 to rotate, so that the dust cleaning brush 443 can clean the dust on the dust-proof net 44. The top column 444 presses the top pressing spring 445, so that the top rod 446 can push out the knocking plate 447, which facilitates the shaking off of the dust on the dust-proof net 44 and avoids blocking of the dust-proof net 44, facilitating the use of the heat dissipation mechanism 4.

[0042] Embodiment 3

[0043] As Figures 1-6As shown in the figure, based on Embodiment 1, the present invention provides a technical solution: Preferably, the lubricating mechanism 5 includes a lubricating box 51, which is fixedly connected to the right side of the driving device 1. A rolling wheel 52 is movably connected to the right side inside the lubricating box 51. A rotating plate 53 is fixedly connected to the top of the rolling wheel 52. A rotating block 54 is fixedly connected to the top of the rotating plate 53. A pulling plate 55 is movably connected to the side of the rotating block 54. A push rod 56 is movably connected to the top of the pulling plate 55. The top end of the push rod 56 is movably connected to a pressing plate 57. The pressing plate 57 is slidably connected inside the lubricating box 51. An oil-absorbing cotton 58 is fixedly connected to the top of the pressing plate 57. An oil guiding groove 59 is opened on the left side of the top of the oil-absorbing cotton 58. The rolling wheel 52 includes a rotating block 521. A connecting shaft 522 is fixedly connected to the middle of the rotating block 521. A bearing 523 is rotatably connected to the side of the connecting shaft 522. The bearing 523 is fixedly connected inside the lubricating box 51. An elastic bent plate 524 is fixedly connected to the side of the rotating block 521. A tightening plate 525 is arranged inside the elastic bent plate 524. The tightening plate 525 is movably connected inside the rotating block 521. A compression spring 526 is fixedly connected to the side of the tightening plate 525.

[0044] In this embodiment, the compression spring 526 is used to squeeze the tightening plate 525, so as to be able to squeeze the elastic bent plate 524, making the elastic bent plate 524 tighten the turntable. When the turntable rotates, the rotation of the rotating block 521 and the connecting shaft 522 can be driven through the bearing 523 by the friction with the elastic bent plate 524, and the rotating plate 53 can be rotated. Thus, the pulling plate 55 can be pulled to move through the rotating block 54, and the pressing plate 57 can be pushed through the push rod 56 to squeeze the oil-absorbing cotton 58, so that the lubricating oil can enter the connection between the five-axis turntable 2 and the driving device 1 through the oil guiding groove 59, lubricating the five-axis turntable 2, reducing the wear of the five-axis turntable 2, and improving the service life of the five-axis turntable 2.

[0045] Embodiment 4

[0046] As Figures 1-6 As shown in the figure, based on Embodiment 1, the present invention provides a technical solution: Preferably, the sound-absorbing mechanism 6 includes a housing 61, which is fixedly connected to the front end of the driving device 1. A sound insulation damping plate 62 is fixedly connected to the inside of the housing 61. A sound-absorbing plate 63 is fixedly connected to the top of the sound insulation damping plate 62. Sound-absorbing holes 64 are opened inside the sound-absorbing plate 63. A sound-absorbing felt 65 is fixedly connected to the bottom end of the sound-absorbing plate 63. A noise reduction sponge 66 is fixedly connected to the bottom end of the sound-absorbing felt 65. A honeycomb sound-absorbing cavity 67 is arranged inside the noise reduction sponge 66.

[0047] In this embodiment, when the turntable is working, the sound-absorbing felt 65 inside the sound-insulating damping plate 62 facilitates the absorption of the noise generated by the driving device 1. The absorbed noise is transmitted to the noise-reducing sponge 66 and the honeycomb sound-absorbing cavity 67 through the sound-absorbing plate 63 and the sound-absorbing holes 64, so that the noise can be eliminated, thereby reducing the impact of the noise on the workers and ensuring that the processing effect of the workers on the workpiece is not affected.

[0048] Next, the working principle of the five-axis turntable for the numerically controlled machine tool will be specifically described.

[0049] As Figures 1-6 shown, when the five-axis turntable 2 is working, the driving device 1 can drive the five-axis turntable 2 to rotate, and the friction with the rolling wheel 52 can drive the rolling wheel 52 to rotate, so that the rotating plate 53 can rotate. Then, through the rotating block 54, the pull plate 55 can be pulled to move, and through the push rod 56, the pressing plate 57 can be pushed to squeeze the oil-absorbing cotton 58, so that the lubricating oil can enter the connection between the five-axis turntable 2 and the driving device 1 through the oil guide groove 59, lubricating the five-axis turntable 2 and reducing the wear of the five-axis turntable 2. Then, the motor 45 can drive the exhaust fan 46 and the guide fan 47 to rotate. Thus, through the guide fan 47, the hot air in the device can be transported to the inside of the cooling chamber 43, and the heat can be absorbed through the heat-conducting copper plate 48 and the refrigerating sheet 49 and conducted to the exhaust chamber 42. After that, the exhaust fan 46 can discharge the heat in the exhaust chamber 42, facilitating the heat dissipation of the device, and the noise generated by the device can be reduced by the silencing mechanism 6, facilitating the use of the five-axis turntable 2.

[0050] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements without departing from the spirit of the present invention are within the protection scope of the present invention.
