[0025] See also Figure 1-5 A metal processing circulating cooling device comprises a casing 1, a vertical frame 2 is fixedly arranged on the inner wall at the top of the casing 1, a motor 3 and a pressure-resistant sealing ring 4 are fixedly arranged on the inner wall at the bottom of the vertical frame 2, dovetail grooves 6 are provided on the inner walls on both sides of the vertical frame 2, dovetail blocks 7 are slidably connected to the inner walls of the two dovetail grooves 6, a sleeve 8 is fixedly arranged between the two dovetail blocks 7, an annular groove 9 is provided inside the sleeve 8, a heat dissipation grid 25 is embedded in the inner wall of the annular groove 9, a liquid inlet hose 10 and a liquid outlet hose 11 are fixedly arranged on the surface of the sleeve 8, the vertical frame 2 is provided with a limit assembly 5, a liquid storage tank 12 is fixedly provided on one side of the casing 1, and a cooling box 13 is fixedly provided on the other side of the casing 1. The sleeve 8 is moved downward to cause the sleeve 8 to press the pressure-resistant sealing ring 4. At this time, the sleeve 8 is sleeved on the outside of the motor 3. The motor 3 exchanges heat with the coolant flowing in the annular groove 9 through the heat dissipation grid 25 to achieve heat dissipation. The sleeve 8 pressed downward is fixed by the limit assembly 5 to ensure the sealing effect. The sleeve 8 lifted upward is fixed by the limit assembly 5, so that both hands are free to repair the motor 3.

[0026] The limiting assembly 5 includes a transverse frame 51 and two slots 55. The transverse frame 51 is fixedly arranged on the inner wall at the top of the vertical frame 2. The inner wall of the transverse frame 51 is rotatably connected with a bidirectional screw rod 52 through a sealed bearing. The surface of the bidirectional screw rod 52 is threadedly connected to two moving frames 53 through a screw nut. The inner walls on one side of the two moving frames 53 are fixed with two blocks 54 engaged with the slots 55. The two slots 55 are respectively opened on one side of the two dovetail blocks 7. The bidirectional screw rod 52 is rotated, and the bidirectional screw rod 52 drives the two moving frames 53 to move. The two moving frames 53 drive the four blocks 54 to move. When the two blocks 54 at the top are inserted into the two slots 55, the fixing of the sleeve 8 after lifting is completed. When the two blocks 54 at the bottom are inserted into the two slots 55, the fixing of the sleeve 8 after descending is completed.

[0027] One side of the four blocks 54 is set as an inclined surface, and the surfaces of the two moving frames 53 are slidably connected to the inner wall of the horizontal frame 51. One end of the bidirectional screw rod 52 passes through the inner wall of the horizontal frame 51 and the inner wall of the vertical frame 2 in turn and is fixed with a turntable. The turntable is convenient for rotating the bidirectional screw rod 52. When moving horizontally, the block 54 can push the slot 55, the dovetail block 7 and the sleeve 8 downward through the inclined surface, so that the sleeve 8 presses the pressure-resistant sealing ring 4 downward to enhance the sealing effect of the pressure-resistant sealing ring 4. The block 54 will be completely aligned with the slot 55 after the pressure-resistant sealing ring 4 is deformed, so that the block 54 will push the dovetail block 7 downward through the inclined surface before the pressure-resistant sealing ring 4 is deformed.

[0028] Two through grooves 14 are provided on the inner walls of one side of the two dovetail grooves 6, and the inner walls of the four through grooves 14 are respectively slidably connected to the surfaces of the four clamping blocks 54, wherein the interiors of the two through grooves 14 are respectively connected to the interiors of the two clamping grooves 55. The through grooves 14 facilitate the clamping blocks 54 to pass through the vertical frame 2, and are used to accommodate the clamping blocks 54 before moving the sleeve 8 in the vertical direction, so as to prevent the clamping blocks 54 from blocking the sliding of the dovetail block 7.

[0029] A submersible pump 15 is fixedly provided on the inner wall at the bottom end of the liquid storage tank 12, and the liquid outlet end of the submersible pump 15 is fixedly connected to one end of the liquid inlet hose 10, and the contact part of the liquid storage tank 12 and the liquid inlet hose 10 is fixedly connected. A liquid replenishing pipe 16 is fixedly provided on the top of the liquid storage tank 12, and a liquid discharge pipe 17 is fixedly provided on the front of the liquid storage tank 12. A first electric valve is fixedly provided on the surface of the liquid discharge pipe 17. The interior of the liquid storage tank 12 is filled with low-temperature coolant. The submersible pump 15 is started, and the submersible pump 15 pumps the coolant into the bottom of the annular groove 9 through the liquid inlet hose 10. After filling the annular groove 9, the coolant is discharged into the interior of the S-shaped condenser 18 through the liquid outlet hose 11. The coolant exchanges heat with the heat dissipation grid 25, and the heat dissipation grid 25 is sleeved on the outside of the motor 3. The heat dissipation grid 25 reduces the temperature of the gas environment in which the motor 3 is located, thereby cooling the motor 3.

[0030] An S-shaped condenser 18 is fixedly provided inside the cooling box 13, one end of the S-shaped condenser 18 is fixedly connected to one end of the liquid outlet hose 11, and the other end of the S-shaped condenser 18 is fixedly connected to one end of the liquid replenishing tube 16. A cold water pipe 19 and a drain pipe 20 are fixedly provided on the front of the cooling box 13, a second electric valve is fixedly provided on the surface of the cold water pipe 19, and a third electric valve is fixedly provided on the surface of the drain pipe 20. External cold water is input through the cold water pipe 19, and warm water is discharged through the drain pipe 20. After entering the S-shaped condenser 18, the coolant exchanges heat with the external cold water, thereby reducing the temperature of the coolant and increasing the temperature of the cold water. The cooled coolant flows back to the interior of the liquid storage tank 12 through the liquid replenishing tube 16, thereby realizing circulating cooling.

[0031] Two through holes 21 are provided at the top of the casing 1, and the inner walls of the two through holes 21 are fixedly provided with combined sealing rings, and the contact parts of the liquid inlet hose 10 and the liquid outlet hose 11 with the two combined sealing rings are slidably connected. When the sleeve 8 moves in the vertical direction, the sleeve 8 will drive a part of the liquid inlet hose 10 and a part of the liquid outlet hose 11 to move. At this time, the liquid inlet hose 10 and the liquid outlet hose 11 slide along the inner walls of the corresponding combined sealing rings. The combined sealing rings are elastic and have excellent wear resistance, which prevents the liquid inlet hose 10 and the liquid outlet hose 11 from rubbing against the hard inner walls of the through holes 21, thereby extending the service life of the liquid inlet hose 10 and the liquid outlet hose 11.

[0032] Two protective doors 22 are hinged on the front of the casing 1. Handles 23 are fixedly provided on the surfaces of the two protective doors 22 and the surface of the sleeve 8. A workbench 24 is fixedly provided on the inner wall of the casing 1. The top of the workbench 24 is used to place the motor casing to be processed. The protective door 22 blocks debris during processing. It should also be emphasized that transmission components and processing tools need to be configured on the transmission shaft of the motor 3 to form a complete machining center.

[0033] When in use, the turntable is rotated to drive the bidirectional screw rod 52 to rotate through the turntable, and the bidirectional screw rod 52 will drive the two moving frames 53 to move, and the two moving frames 53 will drive the four clamping blocks 54 to move, so that the four clamping blocks 54 will be separated from the clamping groove 55 and retracted into the interior of the through groove 14, and the sleeve 8 is moved downward at this time, so that the sleeve 8 is pressed against the pressure-resistant sealing ring 4, and the bidirectional screw rod 52 is rotated in the opposite direction, and the bidirectional screw rod 52 drives the four clamping blocks 54 to move in the opposite direction through the two moving frames 53, so that the two clamping blocks 54 at the bottom are clamped into the interior of the clamping groove 55, and the two dovetail blocks 7 and the sleeve 8 are fixed;

[0034] The submersible pump 15 is started. The submersible pump 15 pumps the coolant into the bottom of the annular groove 9 through the liquid inlet hose 10. The coolant is discharged into the S-shaped condenser tube 18 through the liquid outlet hose 11. The coolant exchanges heat with the heat dissipation grid 25. The heat dissipation grid 25 is sleeved on the outside of the motor 3. The heat dissipation grid 25 reduces the temperature of the gas environment in which the motor 3 is located, thereby cooling the motor 3. After entering the S-shaped condenser tube 18, the coolant exchanges heat with the external cold water, thereby reducing the temperature of the coolant and increasing the temperature of the cold water. The cooled coolant flows back to the inside of the liquid storage tank 12 through the liquid replenishment tube 16, thereby realizing circulating cooling;

[0035] When the motor 3 needs to be repaired, the submersible pump 15 is turned off, and the two blocks 54 at the bottom that fix the two dovetail blocks 7 and the sleeve 8 are released. At this time, the sleeve 8 is moved upward to prompt the sleeve 8 to move away from the motor 3. The sleeve 8 will drive the two dovetail blocks 7 to slide upward along the dovetail groove 6, thereby exposing the motor 3. When repairing the motor 3, there is no need to drain the coolant and remove the sealed sleeve 8, which is more convenient. Then, the bidirectional screw rod 52 is rotated in the opposite direction. The bidirectional screw rod 52 drives the four blocks 54 to move in the opposite direction through the two moving frames 53, prompting the two blocks 54 at the top to be inserted into the inside of the groove 55, thereby completing the fixation of the sleeve 8, making it convenient to free up both hands to repair the exposed motor 3, thereby enhancing practicality.
