All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0028] Refer to Figures 1-5, A spindle box structure with a cooling mechanism, including a spindle box 1, an outer housing 2, and a cooling box 3. The spindle box 1 is arranged inside the outer housing 2. A drive shaft 11 is provided on the spindle box 1. One end of the drive shaft 11 extends to the outside of the outer housing 2 and is rotatably connected to the outer housing 2 in a sealed manner. The cooling box 3 is fixedly installed on one side of the outer housing 2. A liquid inlet pipe 31 and a liquid outlet pipe 32 are fixedly installed on the cooling box 3, and both the liquid inlet pipe 31 and the liquid outlet pipe 32 are communicated with the outer housing 2. An upper rotating shaft 41 and a lower rotating shaft 43 are rotatably installed on the outer housing 2. One end of the upper rotating shaft 41 extends into the liquid inlet pipe 31 and is fixedly sleeved with an impeller 42. One end of the lower rotating shaft 43 is fixedly sleeved with an impeller 44, and the impeller 42 and the impeller 44 are arranged in the opposite direction. When the upper rotating shaft 41 and the lower rotating shaft 43 rotate, it can control the impeller 42 and the impeller 44 to disturb the coolant between the outer housing 2 and the spindle box 1 and convey it into the cooling box 3. A drive gear 4 is fixedly sleeved on the drive shaft 11. The upper rotating shaft 41 and the lower rotating shaft 43 both extend outside the outer housing 2 and are respectively fixedly sleeved with driven gears 45. Both driven gears 45 are engaged with the drive gear 4, and when the drive shaft 11 of the spindle box 1 works, it can provide driving force for the upper rotating shaft 41 and the lower rotating shaft 43. A heat dissipation plate 62 is fixedly installed on the top of the cooling box 3. A plurality of heat absorption mesh plates 6 arranged in parallel are fixedly installed on the inner walls on both sides of the cooling box 3. A plurality of heat conduction plates 61 arranged vertically are fixedly installed on the plurality of heat absorption mesh plates 6. The top sides of the plurality of heat conduction plates 61 all extend above the cooling box 3 and are fixedly connected to the heat dissipation plate 62, which can discharge the heat in the coolant in the cooling box 3, so as to achieve the cooling effect of the coolant, and further achieve the cooling of the spindle box 1. A refrigeration pipe 51 is fixedly installed on the same plurality of heat absorption mesh plates 6. A refrigerator 5 is fixedly installed on the side of the cooling box 3 away from the outer housing 2. Both ends of the refrigeration pipe 51 are connected to the refrigerator 5, and when the heat dissipation plate 62 cannot dissipate heat in a timely and effective manner, it can provide cooling and temperature reduction for the coolant in the cooling box 3, so as to further improve the cooling effect on the spindle box 1.

[0029] In this embodiment, in order to ensure the working stability of the spindle box 1, the upper rotating shaft 41, and the lower rotating shaft 43, a plurality of support blocks 21 are fixedly installed on the top inner wall and the bottom inner wall of the outer housing 2. The plurality of support blocks 21 are all fixedly connected to the spindle box 1, and the two support blocks 21 located in the upper middle position are rotatably connected to the upper rotating shaft 41. A same fixing block is fixedly installed between the bottom inner wall of the outer housing 2 and the bottom of the spindle box 1. The lower rotating shaft 43 is rotatably connected to the fixing block.

[0030] In this embodiment, in order to further disturb the flowing coolant, the plurality of support blocks 21 are all semicircular in shape. The vertical projection surfaces of the two support blocks 21 located on the same vertical axis are circular in shape, and the arc surface of the upper support block 21 faces the direction of the driven gear 45.

[0031] In this embodiment, in order to avoid the insecurity caused by the exposure of the driving gear 4 and the driven gear 45, and at the same time avoid the exposed driving gear 4 and driven gear 45 from affecting the appearance coordination of the device, a protective cover 22 is fixedly installed on the side of the outer housing 2 away from the cooling tank 3, and both the driven gear 45 and the driving gear 4 are located inside the protective cover 22.

[0032] For the circuits, electronic components, and module mechanisms involved, existing technologies are adopted, which can be fully realized by those skilled in the art without further elaboration. The content protected by this application does not involve improvements to software, circuits, and methods.

[0033] Working principle: During use, as the drive shaft 11 on the main spindle box 1 operates, the driving gear 4 and the driven gear 45 cooperate to control the rapid rotation of the upper rotating shaft 41 and the lower rotating shaft 42. Since the first impeller 42 and the second impeller 44 are arranged in opposite directions, they can effectively disturb the coolant between the outer housing 2 and the main spindle box 1 during rotation, promoting the circulating flow of the coolant. The coolant enters the outer housing 2 through the liquid inlet pipe 31, and after being disturbed by the first impeller 42 and the second impeller 44, it flows towards the cooling tank 3. In the cooling tank 3, the coolant passes through the heat absorption mesh plate 6 and the heat conducting plate 61, transferring heat to the heat dissipation plate 62, thereby achieving the cooling effect, and after cooling, it flows back into the outer housing 2 through the liquid storage pipe 32.

[0034] When the heat dissipation plate 62 cannot dissipate heat in a timely and effective manner, the refrigerator 5 is started, and the coolant is further cooled through the refrigeration pipe 51 to ensure that the temperature of the main spindle box 1 is maintained within a reasonable range. The start of the refrigerator 5 can be controlled by a temperature sensor. When it detects that the coolant temperature exceeds the set value, the refrigerator 5 is automatically started to ensure the cooling effect.

[0035] At the same time, in order to ensure the working stability of the main spindle box 1, the upper rotating shaft 41, and the lower rotating shaft 43, a plurality of support blocks 21 fixedly installed on the top inner wall and the bottom inner wall of the outer housing 2, as well as the fixed block located between the bottom inner wall and the bottom of the main spindle box 1, provide stable support for the main spindle box 1. These support blocks 21 not only ensure the stability between the main spindle box 1 and the outer housing 2, but also further promote the turbulent flow effect of the coolant through their semi-circular design. The setting of the protective cover 22 not only improves the operation safety and avoids the possible harm caused by the exposed gears, but also makes the appearance of the entire device more tidy and beautiful. Through these designs, while ensuring the efficient cooling of the equipment, the operation safety and the aesthetics of the equipment are also taken into account.

[0036] The above has introduced in detail a spindle box structure with a cooling mechanism provided by the present utility model. Specific embodiments are applied in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
