[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1 - Figure 4 As shown, the present embodiment provides a robot joint motor with a built-in reducer, comprising a motor protection cover 1, a sealed shell 2 is provided on the outside of the motor protection cover 1, and insertion rods 9 are provided at the four outer corners of the sealed shell 2, a clamping assembly 4 is provided on the outer wall of the motor protection cover 1, and a precision reducer 5 is provided inside the motor protection cover 1, a torque sensor 6 is provided on one side of the precision reducer 5, a brake retainer 7 is provided at one end of the torque sensor 6, and a temperature sensor 8 is provided on one side of the brake retainer 7.

[0022] Preferably, the upper and lower ends of the motor protection cover 1 are provided with connecting blocks 31, the upper and lower ends of the sealing shell 2 are fixedly provided with hinged seats 3, and the two hinged seats 3 are threadedly connected to the inside of the threaded rods 32, and one end of the threaded rods 32 is fixedly connected to the threaded knob, and the clamping assembly 4 includes a fixed frame 41, a clamping plate 42 and a push rod 43, the fixed frame 41 is fixedly connected to the motor protection cover 1, the clamping plate 42 is fixedly installed on the sealing shell 2, and a slot is opened inside the clamping plate 42.

[0023] The threaded rod 32 is offset from the motor protection cover 1, so that the motor protection cover 1 and the sealing shell 2 can be quickly separated and disassembled.

[0024] Preferably, a guide groove 44 is provided inside the fixed frame 41, and a push rod 43 is slidably provided on the outer wall of the guide groove 44. One end of the push rod 43 is fixedly connected to a fixing ring and the fixing ring is fixedly connected to the clamping rod 47. A connecting shaft 48 is slidably provided on the outer wall of the clamping rod 47 and the connecting shaft 48 is fixedly connected to the inner wall of the fixed frame 41. A buffer spring 46 is sleeved on the outer wall of the clamping rod 47 above the connecting shaft 48. One end of the buffer spring 46 is squeezed on the limiting ring 45 and the bottom of the limiting ring 45 is fixedly connected to the inside of the fixed frame 41. The outer wall of the clamping rod 47 and the limiting ring 45 are slidably connected.

[0025] The push rod 43 drives the clamping rod 47 on the fixed ring to move, so that the clamping rod 47 squeezes the buffer spring 46 on the limiting ring 45, which facilitates the reset of the fixed ring on the push rod 43.

When one end of the clamping rod 47 is moved to the internal notch of the clamping plate 42 on the sealing shell 2 and is misaligned, the sealing shell 2 is separated from the motor protection cover 1 by using the insertion rod 9, so that the robot joint motor can be quickly disassembled for maintenance, avoiding problems such as internal aging of the motor caused by long-term use, and rotating through the internal precision reducer 5, and then using the torque sensor 6 and the brake retainer 7 to facilitate the stable use of the robot motor.
