If the south heat is not dissipated, the thermal expansion of the stator and the rotating body is easily caused, and the wear between the two is further increased. Will destroy the service life of its components, so the heat and cooling of the motor or drive bee (10), this is an important part of the design of the wolf is also riding the heat and cooling structure and processing methods; such as China Patent Announcement No. 216953 "Thermal Tube Cooling Device for Vertical Machining Center Spindle", "High Speed Spindle Cold 2 Road Structure" on No. 3, No. 8 of the Announcement, "Tool Machine Spindle Mandrel Cooling", Announcement No. 477262, Announcement No. 520680 No. 549375, "Spindle High-Speed Heat Dissipation Device", No. 549375, "Machining Machine Spindle", No. 573576, "Spindle Master" "Cylinder rapid heat dissipation structure" and the patent pending case of "Air-cooled circuit structure of built-in motor spindle" in the 7th leg of the announcement; and the manufacturing method of the cooling structure of the aforementioned patent is mainly for cutting 1324429, 'A, forming inside Lining: Qing steel sheet group Qianmo pound formation - inner general body) 'The inner lining body (11) can be used to wear a high-speed rotating swivel; surrounding cooling tube: as shown in the first and second figures, will be cooled The system (2), the cold section official (20) is spirally arranged on the outer edge of the inner liner body (11), and the outer edge of the cooling pipe (2〇) is further provided with a return pipe (25) for returning the cooling medium; , 々C, die-cast outer casing: as shown in the first figure, the inner liner (η) surrounding the spiral cooling pipe (20) and the return pipe (25) is placed in the outer casing (• 12) mold, The inner liner body (11) and the cooling pipe (20) and the return pipe (25) are embedded in the outer casing body (12) by a die casting technique, wherein the melting pipe (20) and the return pipe (25) have a higher melting point than the outer casing. The melting point of the body (12), the embodiment of the cooling tube (20) and the return tube (25) of the present invention is a copper tube as an example [the melting point is about 1084C], and the outer shell The body (12) is aluminum or cast iron. The example is [the melting point is about 660 Ϊ and the pound iron is about ii3 〇 °c]. Although the melting point of the cast iron is slightly different from the copper in the data, the actual test is in the cast iron. After the furnace is in contact with the air, it begins to cool down, and after contact with the sand mold, the actual temperature will drop to about 900 degrees, and this part is actually verified by the applicant, there is no copper tube. D. molded cover: as shown in the first and second figures, the two covers (15) (16) are defined as a first cover (15) and a second cover (16), respectively. The cooling pipes (30) (40) are respectively embedded in the molds of the first and second covers (15) (16) respectively, and the cooling pipes (30) (40) are respectively bent around the first and second The cover body (15) (16) corresponds to the inner flange of the bearing, and the cooling pipe (30) (40) is embedded in the first and second covers (15) (16) by a die casting technique, and the first The cooling tube (30) (40) of the second cover (15) (16) can correspond to the outer tube JZ4429 • the cooling tube (20) and the return tube (25) of the housing (12) and the first cover ( 15) Cooling tube (3 0) an injection pipe (31) and an output pipe (35) having a source of communication medium; whereby the 'cooling system (2) allows the cooling pipe (2〇) of the outer casing (12) and the return pipe (25) to be The cooling tubes (3〇) (40) of the first and second covers (15) (16) form a complete circulation loop and cooperate with the injection tube (31) and output of the first cover (π) cooling tube (30) The tube (35), the group constitutes a motor or a cooling system structure that drives the φ spindle. As for the practical application of the present invention, please refer to the first and second figures. When the motor or the driving spindle is in operation, the cooling medium source is provided by the cooling system (2) to the cooling pipe of the first cover (15). (30) The injection pipe (31) is introduced, and is injected into the cooling pipe (2〇) of the outer casing (12) by cooling & (30), and the cooling pipe (4〇) by the second cover (16) after being surrounded by the cooling pipe (2) The return pipe (25) sent to the outer casing (12) is returned to the cooling medium source by the output pipe (35) of the first cover body (15), and passes through the cooling pipes (20), (3〇) and (40). ) Around the inner liner 〇1)' • With the inner flange of the first and second covers (15) (16), this effectively reduces the heat generated by the south speed rotation. Please refer to the second and third figures. In order to achieve the sealing effect of the cooling pipe (2〇) (3〇) (10), the end surface of the cooling pipe (10) on the outer casing (10) is concave. The hole (70) is used to embed the 〇-ring (8), thereby enabling the connection of the cooling (20) (30) (40) to achieve the purpose of the stop; further, when the present invention is applied to the embodiment of the drive spindle , as in the fourth and fifth figures, the shaft sleeve (5〇) or the bearing seat shape 51) of the drive spindle is spirally surrounded by a cooling tube (10) 1324429 with a tip end 12 (61).
