Description of the Invention: [Technical Field] The present invention relates to a method for manufacturing a cooling system for cooling a motor or a driving spindle, and more particularly to a method for reducing the manufacturing cost of a cooling system and improving the cooling and cooling effect. Production method. [Prior Art of the Invention] It is known that the structure of a motor or a drive spindle usually has a stationary fixed body and a relatively high-speed rotating swivel, which is required by the rigidity and accuracy of the rotating body, and this will greatly generate a great relationship with the fixed body. The frictional force, together with the heat of the source, causes high temperature and high heat between the stator and the rotating body. If this high heat is not dissipated, it will easily cause thermal expansion of the stator and the rotating body, increasing both. The wear between the two will further damage the service life of its components. Therefore, the heat dissipation and cooling of the motor or the drive spindle are an important part of the structural design of such products. The industry has also developed a variety of different heat dissipation, cooling and processing. Method; ^ For example, National Patent Bulletin No. 216953 "Heat-tube cooling device for vertical machining machine spindle", "High-speed spindle cooling circuit structure" No. 345998, and "Tool machine spindle spindle" No. 477262 "Cooling device", = "No. 520680" "Spindle phase change rapid heat sink", Announcement No. 549375 "Spindle high-speed heat sink", 563606^ "Processor Spindle", Announcement No. 573576 "Spindle Bearing Sleeve Rapid Heat Dissipation Structure" and Announcement No. M247333 "Pneumatic Cooling Circuit Structure of Built-in Motor Spindle", etc.; The manufacturing method of the cooling structure of the case is mainly to cut 5 200826437 to form a corresponding concave ring groove between the inner liner body or the outer body of the stator of the motor or the driving main shaft, thereby forming a thread-like surrounding circuit. The cooling medium is used to take away the heat source by using the cooling medium, 2 temperature (10), but the concave circuit is formed on the inner and outer edge surfaces of the inner liner or the outer casing, so that it has a certain value when it is cut, ίίί, In addition, the accuracy of the second is required to be turned off at the two ends of the loop of the processing to prevent leakage of the outside of the medium 2, and the overall addition is only slow, and it is extremely easy to produce defective products due to improper processing. The production efficiency of the method is poor, and the manufacturing cost is extremely high; ^ In view of this, the inventor has been engaged in research and development of related industries for many years, and the problem of the cooling device for the above-mentioned motor or the driving spindle is deeply problematic. Discuss and actively seek solutions, sister county research and development, and finally successfully developed a kind of motor: the driving rate difference caused by the method of the present invention. [Inventive content] Therefore, the present invention mainly provides a motor Or the method of driving the master's to simplify the manufacturing difficulty and reduce the "processing efficiency, the downstream can reduce its manufacturing cost. The following technology is called the ^ can or the mold - the internal body, % around the cold department : The cooling pipe is spirally arranged to circumscribe the outer edge of the inner liner 6 200826437 - Molded outer casing: the inner casing of the inner casing of the (four) residual cooling pipe will be surrounded by 'and the (10) casting technology will cool the body and cooling"; In the meantime, the cold material and the contact tube are used to find the point of lack of the swelling body, and the above technical means can make the invention more difficult to manufacture and process, and improve the manufacturing efficiency.
