[0030] Please refer to Figures 1-6 , the present utility model provides a technical solution: a spindle box for a numerical control machine tool, including a base 1, a spindle box protective cover 2 and a numerical control machine tool spindle box 5 are fixedly installed at the upper end of the base 1, the input end and the output end of the numerical control machine tool spindle box 5 both extend out of the spindle box protective cover 2, a heat dissipation component, the heat dissipation component is arranged above the base 1, the heat dissipation component includes a spindle box heat dissipation cover 6 and a heat dissipation fan 9, the spindle box heat dissipation cover 6 is sleeved on the surface of the numerical control machine tool spindle box 5, the heat dissipation fan 9 is arranged inside the spindle box protective cover 2, a plurality of heat dissipation pipes 7 are fixedly connected to the surface of the spindle box heat dissipation cover 6, and a water pipe 8 is fixedly connected to the surface of the spindle box heat dissipation cover 6.

[0031] There are two groups of the spindle box heat dissipation cover 6, the heat dissipation pipes 7 and the water pipe 8, which are symmetrically arranged on both sides of the numerical control machine tool spindle box 5 respectively. The two spindle box heat dissipation covers 6 are of a hollow structure, a connecting water pipe 10 is fixedly connected to the upper ends of the two spindle box heat dissipation covers 6, and the two spindle box heat dissipation covers 6 are fixed on the surface of the numerical control machine tool spindle box 5 through a plurality of fixing bolts.

[0032] A driving motor 11 is fixedly connected to the surface of the spindle box protective cover 2, two rotating shafts 12 are rotatably connected inside the spindle box protective cover 2, chain wheels 13 are fixedly connected to the surfaces of the two rotating shafts 12, the output end of the driving motor 11 is fixedly connected to the corresponding rotating shaft 12, a chain 14 is sleeved on the surfaces of the two chain wheels 13, a connecting block 19 is fixedly connected to the surface of the chain 14, a fixing block 15 is fixedly connected inside the spindle box protective cover 2, a fixing rod 16 is fixedly connected inside the fixing block 15, a moving plate 17 is slidably sleeved on the surface of the fixing rod 16, a fixing frame 18 is fixedly connected to one end of the moving plate 17 close to the chain 14, the connecting block 19 is slidably connected with the fixing frame 18, and the heat dissipation fan 9 is fixedly connected to the moving plate 17.

[0033] The number of the fixing blocks 15 and the fixing rods 16 is two respectively, which are arranged on the inner wall surface of the spindle box protective cover 2, and the two fixing blocks 15 and the two fixing rods 16 are both slidably connected with the moving plate 17.

[0034] A first filter screen 3 and a second filter screen 4 are fixedly connected to the left and right surfaces of the spindle box protective cover 2 respectively.

[0035] When using this spindle box, first connect the water pipe 8 to the cooling circulation equipment of the CNC machine tool, and then introduce cooling water into the interior of the water pipe 8. The cooling water is introduced into the interior of the spindle box heat dissipation cover 6, the heat dissipation pipe 7 and the connecting water pipe 10 from the water pipe 8, and discharged from another water pipe 8. Heat dissipation is carried out through the spindle box heat dissipation cover 6 and the heat dissipation pipe 7, which facilitates the cooling of the spindle box 5 of the CNC machine tool, prevents the spindle box 5 of the CNC machine tool from overheating during operation, thereby affecting the accuracy and stability of the machine tool, can reduce the working temperature, and thus extend the service life.

[0036] After the cooling water, the spindle box heat dissipation cover 6 and the heat dissipation pipe 7 dissipate heat from the spindle box 5 of the CNC machine tool, the dissipated heat may accumulate inside the spindle box protective cover 2, and when it accumulates to a certain extent, it may affect the heat dissipation efficiency of the spindle box heat dissipation cover 6 and the heat dissipation pipe 7.

[0037] At this time, start the drive motor 11 to drive the rotating shaft 12 and the sprocket 13 to rotate. The sprocket 13 drives the chain 14 to rotate. The chain 14 drives the connecting block 19 to slide inside the fixed frame 18. The fixed frame 18 drives the moving plate 17 to slide on the surface of the fixed rod 16, thereby driving the heat dissipation fan 9 to move. At the same time, start the heat dissipation fan 9 to move, which facilitates the heat accumulated inside the spindle box protective cover 2 to be dissipated from the first filter screen 3 and the second filter screen 4, thereby improving the heat dissipation effect of this spindle box. During the movement of the heat dissipation fan 9, the heat dissipation efficiency of the heat dissipation pipe 7 can be improved.

[0038] Since the connecting block 19 is fixedly connected to the chain 14 and the connecting block 19 slides inside the fixed frame 18, when the drive motor 11 drives the chain 14, the reciprocating movement of the moving plate 17 can be realized without changing the direction, converting the one-way rotational movement of the chain 14 into the reciprocating movement of the moving plate 17, improving the stability and reliability of this device.

[0039] Furthermore, through the heat dissipation fan 9, the cooling water, the spindle box heat dissipation cover 6 and the heat dissipation pipe 7 dissipate heat from the spindle box 5 of the CNC machine tool, reducing the working temperature of the spindle box 5 of the CNC machine tool. During the movement of the heat dissipation fan 9, the heat dissipation efficiency of the heat dissipation pipe 7 can be improved, preventing the spindle box 5 of the CNC machine tool from overheating during operation, thereby affecting the accuracy and stability of the machine tool, can reduce the working temperature, and thus extend the service life.

[0040] Through the rotation of the chain 14 and the sliding of the connecting block 19 inside the fixed frame 18, it is convenient for the moving plate 17 to perform reciprocating linear motion. The one-way rotational movement of the chain 14 is converted into the reciprocating movement of the moving plate 17, improving the stability and reliability of this device, the heat dissipation efficiency of this device, and the service life of this device.

[0041] Working principle: When using this spindle box, first connect the water pipe 8 to the cooling circulation equipment of the CNC machine tool, then introduce cooling water into the interior of the water pipe 8, pass the cooling water into the interior of the spindle box heat dissipation cover 6, the heat dissipation pipe 7 and the connecting water pipe 10 from the water pipe 8, and discharge it from another water pipe 8. Heat dissipation is carried out through the spindle box heat dissipation cover 6 and the heat dissipation pipe 7, which is convenient for cooling the spindle box 5 of the CNC machine tool, preventing the spindle box 5 of the CNC machine tool from overheating during operation, thereby affecting the accuracy and stability of the machine tool, reducing the working temperature, and thus prolonging the service life.

[0042] After the cooling water, the spindle box heat dissipation cover 6 and the heat dissipation pipe 7 dissipate heat from the spindle box 5 of the CNC machine tool, the dissipated heat may accumulate inside the spindle box protective cover 2. When it accumulates to a certain extent, it may affect the heat dissipation efficiency of the spindle box heat dissipation cover 6 and the heat dissipation pipe 7.

[0043] At this time, start the driving motor 11 to drive the rotating shaft 12 and the sprocket 13 to rotate. The sprocket 13 drives the chain 14 to rotate. The chain 14 drives the connecting block 19 to slide inside the fixed frame 18. The fixed frame 18 drives the moving plate 17 to slide on the surface of the fixed rod 16, thereby driving the heat dissipation fan 9 to move. At the same time, start the heat dissipation fan 9 to move, which is convenient for dissipating the heat accumulated inside the spindle box protective cover 2 from the first filter screen 3 and the second filter screen 4, thereby improving the heat dissipation effect of this spindle box. During the movement of the heat dissipation fan 9, the heat dissipation efficiency of the heat dissipation pipe 7 can be improved.

[0044] Since the connecting block 19 is fixedly connected to the chain 14 and the connecting block 19 slides inside the fixed frame 18, when the driving motor 11 drives the chain 14, the reciprocating movement of the moving plate 17 can be realized without changing the direction, converting the one-way rotational movement of the chain 14 into the reciprocating movement of the moving plate 17, improving the stability and reliability of this device.

[0045] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the purpose of the present invention.
