Description

Machine tools with temperature control devices Technical Field

[0001] This utility model relates to the field of machine tools, specifically to a machine tool with a constant temperature device. Background Technology

[0002] Machine tools refer to machines that use various cutting or non-cutting methods and appropriate tools to process metallic or non-metallic materials into a certain shape and size, or for the purpose of performing more precise machining. A Chinese patent discloses a machine tool with a thermostatic spindle box (authorization announcement number CN 214922787 U). This patented technology can improve the cooling of the spindle box by setting up water channels and using water cooling. Simultaneously, the cooling water absorbs heat from the heat sink, thereby improving the heat dissipation efficiency of the heat sink. However, it can only dissipate heat from the spindle and cannot raise the temperature of the spindle. In extremely cold regions, when the temperature is below a certain value, the equipment cannot start and operate normally. At this time, it is necessary to raise the temperature of the spindle to reach the temperature required for normal operation. Therefore, those skilled in the art have provided a machine tool with a thermostatic device to solve the problems mentioned in the background art. Summary of the Invention

[0008] The technical effects and advantages of this utility model are as follows:

The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0022] Please refer to Figures 1-7. In this embodiment, a machine tool with a constant temperature device is provided, including a machine tool body 1 and a spindle mechanism 2. The spindle mechanism 2 is arranged in the left part of the machine tool body 1. The spindle mechanism 2 includes a spindle box 3 and a rotary shaft 4. The rotary shaft 4 is rotatably connected inside the spindle box 3. A motor 5 is installed at one end of the rotary shaft 4, and a chuck 6 is installed at the other end of the rotary shaft 4. A constant temperature mechanism 7 is installed inside and on the outer surface of the rotary shaft 4, and the constant temperature mechanism 7 is located inside the spindle box 3.

[0023] The constant temperature mechanism 7 includes an inverted tube 8, a fixed groove ring 9, and a spiral heat exchange tube 14. Several inverted tubes 8 are installed inside the rotating shaft 4, with both ends of the inverted tubes 8 passing through the rotating shaft 4. Fixed groove rings 9 are installed at both ends of the several inverted tubes 8. Circular grooves 10 are symmetrically formed on the inner wall of the fixed groove rings 9. A sliding groove ring 11 is connected inside the fixed groove ring 9. Circular blocks 12 are installed at the upper and lower ends of the groove ring 11, and the circular blocks 12 are located within the circular grooves 10. Fixed tubes 13 are installed on the side of the groove ring 11, and both fixed tubes 13 pass through the main shaft box 3. The spiral heat exchange tube 14 is sleeved on the outer surface of the rotating shaft 4, with both ends of the spiral heat exchange tube 14 passing through the main shaft box 3. A temperature control mechanism 15 is installed at one end of the upper fixed tube 13 and the spiral heat exchange tube 14.

[0024] The temperature control mechanism 15 includes a fixed frame 16 and a C-shaped plate 20. A fan 17 is installed inside the fixed frame 16. A filter screen 18 is installed on the side of the fixed frame 16. A notch 19 is opened inside the fixed frame 16. A base plate 24 is installed on the side of the fixed frame 16. A sliding groove 25 is opened at the upper end of the base plate 24. A threaded rod 26 is rotatably connected inside the sliding groove 25. A motor 27 is installed on the side of the threaded rod 26. A threaded sleeve 28 is fitted on the outer surface of the threaded rod 26. The notch 19 and the upper end of the base plate 24 are both provided with the C-shaped plate 20, and the C-shaped plate 20 is fixedly connected to the threaded sleeve 28. A partition 21 is installed on the inner wall of the C-shaped plate 20, and the partition 21 is located inside the notch 19. A semiconductor cooler 22 and a heating tube 23 are installed at the top inside the C-shaped plate 20, and the semiconductor cooler 22 and the heating tube 23 are arranged on both sides of the partition 21.

[0025] The working principle of this utility model is as follows: When it is necessary to cool the rotating shaft 4, the motor 27 drives the threaded rod 26 to rotate. The threaded rod 26 drives the C-shaped plate 20 to move through the threaded sleeve 28, so that the semiconductor cooler 22 is placed in the notch 19. Then, the semiconductor cooler 22 lowers the internal temperature of the fixed frame 16. At the same time, the fan 17 rotates and blows the cold air in the fixed frame 16 into the fixed tube 13 and the spiral heat exchange tube 14. Heat exchange occurs between the spiral heat exchange tube 14 and the outer surface of the rotating shaft 4. At the same time, the fixed tube 13 blows the cold air into the mating groove ring 11. Then, the cold air enters the C-shaped tube 8 through the fixed groove ring 9. Heat exchange occurs between the C-shaped tube 8 and the inside of the rotating shaft 4, thereby cooling the rotating shaft 4 (when the rotating shaft 4 rotates, it drives the C-shaped tube 8 and the fixed groove ring 9 to rotate, so that the annular block 12 rotates in the annular groove 10).

[0026] When the rotating shaft 4 needs to be heated, the motor 27 drives the threaded rod 26 to rotate, causing the C-shaped plate 20 to move and move the heating tube 23 into the notch 19. Then, the heating tube 23 generates heat and transfers it to the spiral heat exchange tube 14 and the C-shaped tube 8, thereby heating the outside and inside of the rotating shaft 4 at the same time.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
