[0046] As shown in Figure 1 , the present application provides a universal assembly mechanism 100, which comprises a clamping assembly 10, an extension assembly 20 and a first floating module 30. The clamping assembly 10 is used for clamping a first assembly 200. The extension assembly 20 is located at an end of the clamping assembly 10 away from the clamping member 12. The extension assembly 20 is arranged to drive the clamping assembly 10 to move along a first horizontal direction towards a second assembly 300 (refer to Figure 2 ) so as to set the first assembly 200 around the second assembly 300. The two ends of the first floating module 30 are fixedly connected with the clamping assembly 10 and the extension assembly 20 respectively. The first floating module 30 comprises a fixing member 31 and a moving assembly 32 (refer to Figure 2 ) arranged to move towards the side away from the clamping assembly 10 when subjected to force. The moving assembly 32 has a first state of abutting the inner wall of the fixing member 31 and a second state of being spaced apart from the inner wall of the fixing member 31 when subjected to force and moved. When the first assembly 200 and the second assembly 300 are misaligned, the moving assembly 32 is subjected to force and swings to the second state so as to align the first assembly 200 and the second assembly 300. Here, the second assembly 300, the first assembly 200, the clamping assembly 10, the first floating module 30 and the extension assembly 20 are arranged in sequence along the first horizontal direction.

[0047] In this embodiment, by arranging the first floating module 30 with the fixed part 31 and the moving assembly 32 in the universal assembly mechanism 100, and arranging the fixed part 31 and the moving assembly 32 to be capable of relative displacement, when the telescopic assembly 20 drives the clamping assembly 10 to move towards the second assembly part 300, the moving assembly 32 can adjust its relative position with the fixed part 31, so as to adjust the assembly angle of the first assembly part 200 clamped by the clamping assembly 10, so that the first assembly part 200 and the second assembly part 300 can be accurately aligned, and after the first assembly part 200 is assembled in place, the moving assembly 32 returns to the first state that the outer wall thereof is fully attached to the inner wall of the fixed part 31, thereby improving the assembly accuracy of the universal assembly mechanism 100, realizing accurate concentric and coaxial assembly, preventing the cumulative error of the assembly parts from causing the assembly accuracy to be reduced and the assembly angle to be adjusted multiple times, and further improving the assembly efficiency. Here, the first assembly part 200 is a worm, and the second assembly part 300 is a motor shaft. In other embodiments, the first assembly part 200 and the second assembly part 300 can be any assembly parts that need to be assembled, which are not limited here.

In this embodiment, by arranging the fixed part 31 to have the tapered hole 311 extending along the first horizontal direction, and arranging the tapered structure 321 of the moving assembly 32 such that the outer wall thereof is attached to the inner wall of the tapered hole 311 and the first elastic part 322 is arranged such that the two ends thereof are respectively abutted against the tapered structure 321 and the first connecting part 323, i.e. when the first assembly part 200 and the second assembly part 300 are misaligned, the clamping assembly 10 is stressed to move the tapered structure 321 along the first horizontal direction away from one end of the clamping assembly 10 to compress the spring, at this time the outer wall of the tapered structure 321 is spaced apart from the inner wall of the tapered hole 311, and the assembly angle of the clamping assembly 10 can be adjusted by adjusting the swing angle of the tapered structure 321 in the tapered hole 311, thereby further improving the assembly accuracy of the universal assembly mechanism 100.

[0049] As shown in Figure 5As shown, in a further embodiment, the conical structure 321 is a square conical structure 321. In this embodiment, by setting the conical structure 321 as a square conical structure 321, and the conical hole 311 as a square conical hole 311, when the first assembly 200 and the second assembly 300 are misaligned and the square conical structure 321 moves to the second state of being spaced apart from the square conical hole 311, the square conical structure 321 can be angularly adjusted to make one side of the square conical structure 321 abut the side of the square conical hole 311, thereby fixing the preset angle of the square conical structure 321 to a certain extent, ensuring that the first assembly 200 and the second assembly 300 can be accurately aligned after adjustment, and ensuring the stability of the assembly angle during assembly.

In this embodiment, the second floating module 50 is connected to the telescopic assembly 20 through the second connecting piece 40, and the second floating module 50 is arranged on one side of the telescopic assembly 20. When the first assembly 200 and the second assembly 300 are misaligned, the second floating module 50 provides an elastic force along the first horizontal direction to the clamping assembly 10, the first floating module 30, and the telescopic assembly 20, preventing rigid collision of the telescopic assembly 20, the first floating module 30, and the clamping assembly 10 caused by misaligned contact of the first assembly 200 and the second assembly 300, thereby improving the structural stability of the universal assembly mechanism 100 and further improving the service life of the universal assembly mechanism 100.

In this embodiment, by arranging the proximity sensor 60 on one side of the first floating module 30, the displacement of the second floating module 50 is detected, so that when the first assembly part 200 is misaligned and clamped to the second assembly part 300 and cannot continue to move when the clamping assembly 10 is moved towards the second assembly part 300 by the telescopic assembly 20, the second floating module 50 is forced to move away from the end of the clamping assembly 10. At this time, the proximity sensor 60 detects the displacement of the second floating module 50 and controls the telescopic assembly 20 to move the clamping assembly 10 away from the second assembly part 300, preventing the first assembly part 200 and the second assembly part 300 from being misaligned and clamped to continue assembly, resulting in structural damage, and further improving the assembly stability of the universal assembly mechanism 100.
