DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a circulating cooling device for mechanical processing, comprising a base 1, a liquid storage tank 2 is installed inside the base 1, guide rails 3 are connected on both sides of the base 1, a filter box 4 is slidably installed on the base 1 through the guide rails 3, connecting strips 27 are connected on both sides of the filter box 4, a handle 28 is connected in front of the filter box 4, a filter hole 29 is provided at the bottom of the filter box 4, the connecting strip 27 is slidably connected in the guide rail 3, a workbench 5 is connected above the base 1, a processing groove 6 is provided on the workbench 5, and chip dropping openings 7 are provided on both sides of the processing groove 6, and the sliding of the connecting strip 27 on the guide rail 3 allows the staff to pull the filter box 4 through the handle 28, thereby quickly installing and disassembling the filter box 4, which is convenient for the staff to collect and process metal debris.

[0022] A mounting plate 8 is connected to one side of the workbench 5, a guide column 9 is connected above the workbench 5, a spindle box 10 is installed on the guide column 9, first heat dissipation ports 11 are provided on both sides of the spindle box 10, a dustproof net 12 is connected inside the spindle box 10, a processing head 14 is installed below the spindle box 10, a fan 13 is installed above the spindle box 10, a vent 22 is provided on the fan 13, a heat-conducting inner wall 15 is connected inside the spindle box 10, a second heat dissipation port 17 is provided on the heat-conducting inner wall 15, and the high-temperature gas inside the spindle box 10 is extracted by the fan 13, thereby accelerating the circulation speed of the air in the spindle box 10 and allowing the heat to be quickly dissipated, while the dustproof net 12 can prevent dust from entering the spindle box 10.

[0023] A cooling pipe 18 is connected between the heat-conducting inner wall 15 and the spindle box 10. The cooling pipe 18 is of a spiral design and is wound around the heat-conducting inner wall 15. Connecting pipes 19 are connected to both ends of the cooling pipe 18. A spray head 20 is connected to the connecting pipe 19 at one end of the cooling pipe 18, and a water pipe 21 is connected to the connecting pipe 19 at the other end of the cooling pipe 18. There are four spray heads 20 in total and they pass through the spindle box 10 and evenly surround the machining head 14. A water pump 16 is installed on one side of the liquid storage tank 2. The water pipe 21 passes through the spindle box 10 and the workbench 5 and is connected to the water pump 16. By winding the cooling pipe 18 around the heat-conducting inner wall 15, the coolant flowing inside the cooling pipe 18 can quickly absorb the heat on the heat-conducting inner wall 15, thereby reducing the heat generated by the rotation of the spindle. Then the coolant will flow out from the spray head 20 and spray on the machining head 14, thereby reducing the heat on the machining head 14.

[0024] A smooth rod 23 is connected inside the processing groove 6, and a motor 24 is installed on the mounting plate 8. A threaded rod 25 is connected to the output shaft of the motor 24, and a scraper 26 is threadedly connected to the threaded rod 25. The threaded rod 25 is rotatably installed inside the processing groove 6, and one end of the scraper 26 away from the threaded rod 25 is slidably connected to the smooth rod 23. A brush is arranged under the scraper 26. When one end of the scraper 26 moves along the threaded rod 25, the other end of the scraper 26 will slide on the smooth rod 23 at the same time, thereby limiting the movement of the movable plate through the smooth rod 23 to prevent the scraper 26 from tilting and rotating to affect the cleaning effect.

[0025] The working principle of the utility model is:

[0026] When machining mechanical parts, the heat generated by the high-speed rotation of the spindle will be absorbed by the heat-conducting inner wall 15. At the same time, the water pump 16 extracts the coolant in the liquid storage tank 2 and transports it to the inside of the cooling pipe 18 through the water pipe 21. The cooling pipe 18 spirally wound on the heat-conducting inner wall 15 allows the coolant to evenly contact the heat-conducting inner wall 15, so that the coolant flowing in the cooling pipe 18 quickly and evenly absorbs the heat on the heat-conducting inner wall 15, reducing the heat generated by the rotation of the spindle. Finally, the coolant will flow out from the spray head 20 and spray on the machining head 14. On, thereby reducing the heat on the processing head 14, after the part processing is completed, the motor 24 is started to rotate the threaded rod 25, so that the scraper 26 can move along the threaded rod 25 in the processing tank 6, so that the metal debris in the processing tank 6 is cleaned by the brush under the scraper 26, and the coolant is pushed into the chip drop port 7 together, and the metal debris falls into the filter box 4 together with the coolant, and the coolant therein will be filtered out from the filter hole 29 and flow into the liquid storage tank 2, while the metal debris will remain in the filter box 4, thereby separating the coolant from the metal debris.
