[0058] Transmission assembly 630: The transmission assembly 630 is disposed below the connection assembly 620;

[0067] Special-shaped connecting rod 622: The bottom of the special-shaped connecting rod 622 is rotatably connected to the upper surface of the second bevel gear 612 via a rotating shaft, and one side of the special-shaped connecting rod 622 close to the upper surface of the cooling box body 1 is fixedly connected to the upper surface of the cooling box body 1.

[0068] The above scheme is adopted: when the auxiliary motor 650 starts to run, the auxiliary motor 650 drives the connecting rod 621 to rotate, and the rotation of the connecting rod 621 drives the first bevel gear 611 to rotate; the special-shaped connecting rod 622 mainly plays the effect of stabilizing the second bevel gear 612 in its original position when the second bevel gear 612 is rotating.

[0072] By adopting the above scheme, when the second bevel gear 612 starts to rotate, it can drive the forward and reverse threaded rod 631 to rotate together. Since the outer surface of the forward and reverse threaded rod 631 is movably connected with the inner surface of the transmission block 632 through threads, the rotation of the forward and reverse threaded rod 631 causes the transmission block 632 to move on the surface of the forward and reverse threaded rod 631, and the transmission block 632 drives the hose 3 to move together, finally achieving the effect of the nozzle 2 spraying oil mist up and down.

[0073] refer to Figure 2 As shown, the fixing assembly 640 includes:

[0075] Fixing member 642: The opposite side of the fixing member 642 is fixedly connected to the inner surface of the cooling box body 1, and the lower surface of the forward and reverse threaded rod 631 is rotatably connected to the inner surface of the fixing member 642 through a rotating shaft.

[0076] The above scheme is adopted: the fixing sleeve 641 mainly fixes the auxiliary motor 650 on the outer surface of the cooling box 1 to provide a support point for the auxiliary motor 650; the fixing part 642 mainly provides a fulcrum for the forward and reverse threaded rod 631 when the forward and reverse threaded rod 631 rotates, so that it is stable in the current position.

[0077] refer to Figure 2 As shown, a filter assembly 7 is provided inside the oil storage tank 5, and two filter assemblies 7 are provided. The two filter assemblies 7 include:

[0080] Adopting the above scheme: when the nozzle 2 sprays the oil in the form of mist, a large amount of oil mist is sprayed on the surface of the component, and a part of the oil mist will slide down along the surface of the component and flow into the filter 701 along the outer surface of the trapezoidal block 702. The filter 701 isolates the impurities inside the flowing oil mist, and the remaining oil mist flows into the oil storage tank 5, thereby achieving the effect of recycling.

[0082] Telescopic column 801: The telescopic column 801 penetrates the inner surface of the trapezoidal block 702, and the outer surface of the telescopic column 801 is fixedly connected to the inner surface of the trapezoidal block 702;

[0083] Placement column 802: The bottom surface of the placement column 802 is fixedly connected to the upper surface of the telescopic column 801;

[0085] Gear 804: The outer surface of the gear 804 and the outer surface of the toothed plate 803 are in a mutually meshing relationship;

[0086] Connecting column 805: The rear end surface of the connecting column 805 is fixedly connected to the front end surface of the gear 804;

[0087] Main motor 806: The output end of the main motor 806 is fixedly connected to the front end face of the connecting column 805, and the right end face of the main motor 806 is fixedly connected to the left end face of the oil storage tank 5.

[0088] The above scheme is adopted: when the staff needs to put parts into the placement column 802, the controller is used to start the main motor 806, and the main motor 806 drives the connecting column 805 to rotate. The connecting column 805 rotates and drives the gear 804 to rotate together. Since the gear 804 and the tooth plate 803 are in a mutual meshing relationship, the rotation of the gear 804 drives the tooth plate 803 to move upward, and the tooth plate 803 can drive the telescopic column 801 to extend and retract the telescopic column 801 upward. Since the placement column 802 is fixed on the upper surface of the telescopic column 801, the telescopic column 801 drives the placement column 802 to move upward. After reaching a certain height, the staff puts the parts on the placement column 802, and then uses the main motor 806 to lower the telescopic column 801 to its initial position.

[0090] During use, when the parts are processed and need to be cooled, the staff needs to put the parts into the placement column 802, use the controller to start the main motor 806, the main motor 806 drives the connecting column 805 to rotate, the connecting column 805 rotates and drives the gear 804 to rotate together, because the gear 804 and the tooth plate 803 are in a mutually meshing relationship, the gear 804 rotates and drives the tooth plate 803 to move upward, and the tooth plate 803 can drive the telescopic column 801 to extend and retract upward. 02 is fixed on the upper surface of the telescopic column 801, so the telescopic column 801 drives the placement column 802 to move upward. After reaching a certain height, the staff puts the parts on the placement column 802, and then uses the main motor 806 to lower the telescopic column 801 to the initial position. The controller is used to start the oil pump 4, and the oil pump 4 extracts the oil inside the oil storage tank 5 and transports it to the hose 3. The oil is sprayed from the nozzle 2 through the hose 3. The nozzle 2 sprays the oil in a mist form and sprays it onto the surface of the parts. During the spraying, the controller starts the auxiliary motor 650, and the auxiliary motor 650 starts During operation, the auxiliary motor 650 drives the connecting rod 621 to rotate, and the rotation of the connecting rod 621 drives the first bevel gear 611 to rotate. Since the first bevel gear 611 and the second bevel gear 612 are in a meshing relationship with each other, the first bevel gear 611 can drive the second bevel gear 612 to rotate, and the rotation of the second bevel gear 612 can drive the forward and reverse threaded rod 631 to rotate together. Since the outer surface of the forward and reverse threaded rod 631 is movably connected with the inner surface of the transmission block 632 through a threaded connection, the rotation of the forward and reverse threaded rod 631 drives the transmission block 632 to rotate. The movable block 632 moves on the surface of the positive and negative threaded rod 631, and the transmission block 632 drives the hose 3 to move together, and finally realizes the effect of the nozzle 2 spraying the oil mist up and down. When the nozzle 2 sprays the oil in the form of mist, a large amount of oil mist is sprayed on the surface of the parts. A part of the oil mist will slide down along the surface of the parts and flow into the filter 701 along the outer surface of the trapezoidal block 702. The filter 701 isolates the impurities inside the flowing oil mist, and the remaining oil mist flows into the oil storage tank 5 to achieve the effect of recycling.
