It is widely used in various fields that require precise rotational control, such as industrial automation production lines, scientific research experimental equipment, test and measurement instruments, aerospace simulation devices, etc. It can be used in various scenarios such as material transfer, workpiece positioning, angle adjustment, posture control, etc., providing reliable and efficient rotational power support for various systems.

[0003] After searching, the Chinese patent with application number CN202320956308.8 discloses a built-in direct-drive reduction five-axis cradle turntable mechanism. The excessive volume seriously affects the processing workspace and cannot meet the existing usage needs. Therefore, the torque required to be provided by the direct-drive motor structure is reduced, so that the set power of the direct-drive motor structure is greatly reduced, and the volume is reduced accordingly, making corresponding space for cutting processing; at the same time, the direct-drive motor structure and the reduction mechanism are embedded in the cradle support, which can further make corresponding space for cutting processing.

After the turntable has been used for a long time, the motor will overheat and cause performance degradation. It is not convenient to dissipate heat and cool the built-in motor, which can easily cause the motor to overheat and cause damage to the internal parts of the motor, thereby reducing the service life of the motor and affecting the efficiency of the motor's rotation output.

The pinion 5 and the ring gear 13 are meshingly connected. The cooling fan 6 is used to perform air cooling on the motor body 3, and the condenser 10 is used to facilitate liquid cooling of the motor body 3. The heat sink 9 is made of copper, which can dissipate heat quickly, is resistant to high temperature and oxidation, and has a relatively long service life.

[0034] As attached Figure 8 As shown, the interior of the mounting groove 14 is slidably connected with a mounting block 15, and the exterior of the two mounting blocks 15 is fixedly connected with a turntable plate 16. The turntable plate 16 is installed into the interior of the ring gear 13 using the two mounting blocks 15. The mounting blocks 15 play a limiting role for the turntable plate 16, and a square groove is provided at the bottom of the turntable plate 16. A square block is provided inside the ring gear 13. The engagement between the square groove and the square block facilitates improving the stability of the ring gear 13 during rotation.

[0035] As attached Figure 6As shown, mounting grooves 14 are provided at both ends of the gear ring wheel 13, and connecting grooves 17 are provided inside the left and right ends of the gear ring wheel 13. The top end of the connecting groove 17 is rotatably connected with a rotating knob 18, and the bottom end of the rotating knob 18 is fixedly connected with a bevel gear 19. The rear end of the connecting groove 17 is rotatably connected with a rotating rod 20, and the other end of the rotating rod 20 is fixedly connected with a bevel gear 21. The bevel gear 19 and the bevel gear 21 are meshedly connected, and a screw rod 22 is fixedly connected to the middle part of the bevel gear 21, and the external thread of the screw rod 22 is connected with an internal thread sleeve 23.

[0037] Working principle: When the reduction turntable is in use, first turn on the motor body 3, use the motor body 3 to drive the reducer 4 to move, and then drive the pinion 5 to rotate through the reducer 4, so that the pinion 5 drives the ring gear 13 to rotate, and then the ring gear 13 drives the installed turntable plate 16 to rotate, which is beneficial to the movement of the reduction turntable. When it is necessary to dissipate heat and cool the motor body 3, first inject coolant into the inside of the condenser tube 10 through the liquid inlet pipe 11, so that the coolant circulates inside the condenser tube 10, which is convenient for liquid cooling and heat dissipation, and then turn on the cooling fan 6, so that the cooling fan 6 uses the air inlet plate 7 to absorb air and transmit the wind force to the inside of the mounting shell 2, and then discharges air through multiple air outlet slots 8, which is convenient for air cooling circulation to dissipate heat, and with the auxiliary heat dissipation of the heat dissipation plates 9 on both sides, it is convenient to improve the heat dissipation efficiency. , thereby facilitating the heat dissipation of the motor body 3. When the turntable plate 16 needs to be installed into the interior of the gear ring wheel 13, the turntable plate 16 drives the mounting blocks 15 on both sides so that the mounting blocks 15 slide into the interior of the mounting groove 14, and then the rotating knob 18 is twisted to facilitate the rotating knob 18 to drive the bevel gear 1 19 to rotate. Through the meshing of the bevel gear 19 and the bevel gear 21, the bevel gear 1 19 drives the bevel gear 21 to rotate, so that the bevel gear 21 drives the screw rod 22 to rotate. When the screw rod 22 rotates, it drives the internal threaded sleeve 23 to move toward the mounting block 15 stuck in the mounting groove 14, so as to facilitate the tightening of the mounting block 15, which is beneficial to improve the tightness of the installation of the mounting block 15, thereby facilitating the installation of the turntable plate 16. The operation during disassembly is reversed, thereby improving the convenience of replacing the turntable plate 16.
