However, the entire motor housing is an integral whole and cannot be disassembled. In this way, if the heat dissipation device fails, it is inconvenient to replace and repair it, which in turn affects the heat dissipation of the servo motor and shortens the service life of the servo motor.

[0015] The beneficial effects of the present invention are:

[0016] By setting a limit device, when replacing the heat dissipation mechanism, first bend the limit plate aside so that the limit plate no longer hinders the movement of the threaded rod. At this time, the threaded rod is turned out from the mounting frame, and then the mounting cross plate is pressed to drive the lifting rod to move downward, so that the upper end of the lifting rod is separated from the motor housing, and then the plug-in circular plate and the mounting ring can be taken out from the rear end of the motor housing.

The hair dryer blows air to the motor body through the through hole to achieve faster heat dissipation, thereby facilitating the disassembly and assembly of the heat dissipation mechanism to ensure that the heat dissipation will not deteriorate.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 3 A new type of servo motor includes a motor housing 1. In order to ensure that the heat dissipation mechanism is stably installed on the inner side of the motor housing 1, a limiting device is arranged inside the motor housing 1. The limiting device includes two threaded rods 2, a lifting rod 3, a spring 4, a fixed horizontal plate 5 and a mounting frame 6. The threaded rod 2 passes through the inside of the fixed horizontal plate 5 and turns into the mounting frame 6 to limit the fixed horizontal plate 5. The spring 4 pushes the lifting rod 3 upward.

[0023] In order to facilitate the limiting of the plug-in circular plate 11, the plug-in circular plate 11 is slidably inserted into the inner side of the rear end of the motor housing 1, and a mounting ring 12 is installed on the left surface of the plug-in circular plate 11. The mounting frame 6 is fixedly installed on the inner surface of the mounting ring 12. A sliding groove 61 is provided inside the mounting frame 6. The plug-in circular plate 11 is inserted into the rear end of the motor housing 1, which is convenient for tense disassembly and assembly. The limiting mechanism on the mounting ring 12 facilitates the limiting of the plug-in circular plate 11.

[0024] In order to ensure that the mounting ring 12 and the motor housing 1 remain stable, the lifting rod 3 is slidably inserted into the inside of the slide groove 61, and the spring 4 is fixedly installed on the lower surface of the lifting rod 3. The lower end of the spring 4 is fixedly connected to the lower inner wall of the slide groove 61. The upper end of the lifting rod 3 passes through the inside of the mounting ring 12 and is slidably inserted into the inside of the motor housing 1. The spring 4 squeezes the lifting rod 3 so that the upper end of the lifting rod 3 passes through the mounting ring 12 and is inserted into the motor housing 1, so that the mounting ring 12 and the motor housing 1 remain relatively stable.

[0025] In order to ensure that the lifting rod 3 will not detach from the motor housing 1, the fixed cross plate 5 is fixedly installed on the outer surface of the lifting rod 3, and the two threaded rods 2 are respectively threadedly connected to the inside of the two ends of the fixed cross plate 5, and the two threaded rods 2 are horizontally symmetrically distributed with the axis of the fixed cross plate 5 as the symmetry center. The lower end surface of the threaded rod 2 is connected to the internal thread of the mounting frame 6, and the threaded rod 2 is threadedly connected to the inside of the fixed cross plate 5 and the mounting frame 6, so that the position of the fixed cross plate 5 and the lifting rod 3 remains stable, ensuring that the lifting rod 3 will not detach from the motor housing 1.

[0026] In order to ensure that the threaded rod 2 will not easily detach from the mounting frame 6, circular grooves 62 are provided on both sides of the slide groove 61 inside the mounting frame 6, and torsion springs 63 are fixedly installed inside the two circular grooves 62. A rotating rod 64 is fixedly installed on the upper end of the torsion spring 63, and a limiting plate 65 is fixedly installed on the upper surface of the rotating rod 64. The lower surface of the limiting plate 65 contacts the upper surface of the threaded rod 2. The torsion force of the torsion spring 63 can twist the rotating rod 64, so that the limiting plate 65 is always kept above the threaded rod 2, so that the threaded rod 2 will not easily detach from the mounting frame 6.

[0027] In order to facilitate the heat dissipation of the motor body 15, a rotating circular plate 66 is fixedly installed on the outer surface of the lower end of the rotating rod 64, and the outer surface of the rotating circular plate 66 is rotatably connected to the inside of the mounting frame 6. A hair dryer 13 is fixedly installed on the right end surface of the plug-in circular plate 11, and a mounting circular plate 14 is fixedly installed inside the motor housing 1. The motor body 15 is fixedly installed on the right side surface of the mounting circular plate 14. A through hole 16 is opened inside the mounting circular plate 14. The rotating circular plate 66 keeps the rotating rod 64 stuck in the mounting frame 6 for stable rotation, and the hair dryer 13 blows air to the motor body 15 through the through hole 16 to achieve faster heat dissipation.

[0028] By setting a limit device, when replacing the heat dissipation mechanism, first bend the limit plate 65 aside so that the limit plate 65 no longer hinders the movement of the threaded rod 2. At this time, the threaded rod 2 is rotated out of the mounting frame 6, and then the mounting cross plate is pressed to drive the lifting rod 3 to move downward, so that the upper end of the lifting rod 3 is separated from the motor housing 1, and then the plug-in circular plate 11 and the mounting ring 12 can be taken out from the rear end of the motor housing 1. During installation, the spring 4 squeezes the lifting rod 3 so that the upper end of the lifting rod 3 passes through the mounting ring 12 and is inserted into the motor housing 1. The hair dryer 13 blows air to the motor body 15 through the through hole 16 to achieve faster heat dissipation, thereby facilitating the disassembly and assembly of the heat dissipation mechanism to ensure that the heat dissipation will not deteriorate.

[0029] Working principle: When replacing the heat dissipation mechanism, first bend the limit plate 65 aside so that the limit plate 65 no longer hinders the movement of the threaded rod 2. At this time, turn the threaded rod 2 out of the mounting frame 6, and then press the mounting cross plate to drive the lifting rod 3 to move downward, so that the upper end of the lifting rod 3 is separated from the motor housing 1, and then the plug-in circular plate 11 and the mounting ring 12 can be taken out from the rear end of the motor housing 1. During installation, the spring 4 squeezes the lifting rod 3 so that the upper end of the lifting rod 3 passes through the mounting ring 12 and is inserted into the motor housing 1, and the hair dryer 13 blows air to the motor body 15 through the through hole 16 to achieve faster heat dissipation.
