The cooling device 2 includes a cooling box 201. The bottom end of the cooling box 201 is fixedly connected to the inner wall of one side of the tank body 1. Rotary shafts 202 are movably connected to both sides of the top of the cooling box 201. The bottom ends of the two rotating shafts 202 are rotatably connected to the lower inner wall of the cooling box 201, respectively. A sprocket 203 is fixedly connected to the top of each of the two rotating shafts 202. A chain 204 is meshed with the outer surfaces of the two sprockets 203. A support plate 205 is fixedly connected to the top of the cooling box 201. A motor 206 is fixedly connected to the lower inner wall of the support plate 205. The output end of the motor 206 is connected to one of the... The top of the sprocket 203 is fixedly connected. After the motor 206 starts, its output end drives one of the sprockets 203 to rotate. Since the two sprockets 203 are connected by the chain 204, the other sprocket 203 also rotates. The rotation of the sprocket 203 drives the rotating shaft 202 to rotate. Multiple stirring rollers 207 are fixedly connected to the outer surface of the two rotating shafts 202. Multiple stirring rollers 207 with the same height and arranged in a ring array form a group. The multiple stirring rollers 207 are arranged in three groups with the upper and lower sides. An oil inlet pipe 208 is fixedly connected to one end of the cooling box 201. The outer surface of the oil inlet pipe 208 is fixedly connected to one end of the box body 1. An oil drain pipe 209 is fixedly connected to the lower part of one end of the cooling box 201. An oil drain valve 210 is provided on the outer surface of the oil drain pipe 209. The outer surface of the oil drain pipe 209 is fixedly connected to one end of the box body 1.

[0022] The stirring roller 207 stirs the cooling oil. The stirring function can make the cooling oil dissipate heat evenly and avoid local overheating. On the other hand, it can accelerate the heat exchange rate between the cooling oil and the inner wall of the cooling tank 201, improve the cooling efficiency, and facilitate the cooling of the cooling oil.

[0023] The conveying device 3 includes a pump body 31. A bracket 32 ​​is fixedly connected to the lower part of the outer surface of the pump body 31. The bottom end of the bracket 32 ​​is fixedly connected to the lower inner wall of the box 1. An oil delivery pipe 33 is fixedly connected to the input end of the pump body 31. An oil outlet pipe 34 is fixedly connected to the output end of the pump body 31. The outer surface of the oil outlet pipe 34 is curved to adapt to the internal spatial layout of the box 1 and also to play a certain buffering role.

The cooling oil after being cooled by the cooling box 35 will enter the machine tool, which can effectively deliver the cooling oil into the machine tool.

[0025] Working principle: After the motor 206 starts, its output end drives one of the sprockets 203 to rotate. Since the two sprockets 203 are connected by the chain 204, the other sprocket 203 also rotates. The rotation of the sprocket 203 drives the rotating shaft 202 to rotate, which in turn causes the stirring roller 207 fixed on the outer surface of the rotating shaft 202 to start rotating. When the high-temperature cooling oil enters the cooling tank 201 through the oil inlet pipe 208, the stirring roller 207 stirs the cooling oil. The stirring function can, on the one hand, make the cooling oil dissipate heat evenly and avoid local overheating, and on the other hand, accelerate the heat exchange rate between the cooling oil and the inner wall of the cooling tank 201, improve the cooling efficiency, and thus achieve the purpose of facilitating the cooling of the cooling oil.

[0026] After the pump body 31 is started, cooling oil is drawn from the housing 1 through the oil supply pipe 33. After being pressurized by the pump body 31, the cooling oil enters the oil outlet pipe 34 from the output end of the pump body 31. The oil outlet pipe 34 has a curved design, which can adapt to the internal space layout of the housing 1 and also play a certain buffering role to reduce the impact of the oil flow. The oil outlet pipe 34 is fixedly connected to both ends of the cooling box 35. The cooling oil enters the cooling box 35 and exchanges heat with the external cooling medium to further reduce the temperature of the cooling oil. The cooling oil cooled by the cooling box 35 will enter the machine tool, thereby achieving the purpose of effectively delivering the cooling oil into the machine tool.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
