[0016] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0017] EMBODIMENT

[0018] As shown in Figure 1 and Figure 2 , a conical self-locking mechanism, the conical surface locking piece 1 has a threaded hole and a shaft pin hole, the outer conical stop disc 3 can be fixed to the conical surface locking piece 1 through the inner hexagonal countersunk screw 6 to form an outer conical assembly; the inner conical disc 2 and the inner conical stop disc 4 are connected through the tight nail screw 5 to form an inner conical assembly. The inner and outer conical assemblies both have a limiting boss which can be staggered and matched.

[0019] As shown in Figure 3 , first, align the outer conical assembly and the inner conical assembly with the center, adjust the outer conical stop disc 3 and the inner conical stop disc 4 until they mesh with each other, and then completely insert them into the center to limit the displacement and rotation in all directions, and finally complete the assembly.

[0020] The locking mechanism mainly adjusts the two nominal conical diameters and the tolerance conical length to achieve the purpose of adjusting the nominal taper. The inner conical disc 2 mainly includes an inner conical surface corresponding to the conical surface locking piece 1, and the conical angle tolerance should meet the standard, which at least needs to ensure that the contact area after matching is more than 80% to have enough static friction to ensure self-locking. At the same time, the limiting bosses of the outer conical stop disc 3 and the inner conical stop disc 4 cross and mesh, further improving the stability of the fixation and the speed of locking the concentricity.

[0021] The embodiment aims to realize efficient and stable self-locking effect through innovative structural design. The self-locking mechanism mainly consists of an inner conical disc 2, a conical surface locking piece 1 and a limiting stop disc. The conical surface locking piece is designed with a tapered surface, which forms a tapered fit with the corresponding tapered hole on the matching piece. Through the action of the limiting device, the conical surface locking piece and the matching piece are tightly fitted. The mechanism utilizes the principle of tapered fit and combines mechanical structure design, so that the contact area gradually increases after assembly, and the locking force is more evenly distributed, thereby realizing efficient and reliable self-locking effect.

[0022] The above-described embodiments only express the specific implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
