[0061] The implementation principle of an assembly device in the embodiment of the present application is as follows: the main body 11 with the guide rail 12, the slider 14, the screw rod 21 and the nut seat 3 is placed in the placement groove of the assembly table 5. Then, the two fourth limiting blocks 73 and the two fifth limiting blocks 74 on the same moving block 72 are used to abut against the two sliders 14 on the same guide rail 12, so as to limit the four sliders 14 on the two guide rails 12.

[0062] Then adjust the position of the first limiting block 64 and make the connecting block 65 located in the accommodating groove 111 of the main body 11; then move the second fixing block 32 so that the second fixing block 32 contacts the first limiting block 64. Before the second fixing block 32 contacts the first limiting block 64, the second fixing block 32 will first push the first adjusting block 81 to move, so that the second adjusting block 84 moves toward the direction of the second supporting block 83 towards the second fixing block 32. At this time, the first spring 82 is in a compressed state, the second spring 86 is in a normal state, and there is a certain distance between the positioning block 85 and the second fixing block 32.

[0063] After the second fixed block 32 contacts the first limiting block 64, the second motor 681 is started, so that the second rotating shaft 683 drives the first rotating shaft 66 to rotate, and the first rotating shaft 66 drives the second limiting block 67 to rotate, and the second limiting block 67 contacts the side of the second fixed block 32 away from the first limiting block 64. When the second rotating shaft 683 rotates, the adjustment block 91 drives the second supporting block 83 to move toward the direction close to the second fixed block 32, and the overall length of the telescopic shaft 873 formed by the main shaft and the secondary shaft becomes shorter; at this time, the positioning block 85 will contact the peripheral side wall of the second fixed block 32, and the second spring 86 is in a normal state; then the second fixed block 32 is rotated, and when the second oil inlet hole 321 on the second fixed block 32 is aligned with the positioning block 85, the second spring 86 restores its elastic deformation, and under the action of the elastic force of the second spring 86, the end of the positioning block 85 away from the second adjustment block 84 will enter the second oil inlet hole 321 of the second fixed block 32.

[0064] Then install the slide 13 so that one end of the first fixed block 31 is located in the installation groove of the slide 13, the side of the second fixed block 32 away from the first limiting block 64 abuts against the slide 13, and the four sliders 14 all abut against the slide 13; at this time, the second limiting block 67 is located below the slide 13, the third oil inlet hole 322 on the second fixed block 32 is aligned with the first oil circuit 131 on the slide 13, and the oil outlet hole on the slider 14 is aligned with the fifth oil circuit 1323 on the slide 13; then, the first connecting bolt is passed through the first through hole on the slide 13 and threadedly connected with the first threaded hole on the slider 14 to fix the slider 14 to the slide 13; the second connecting bolt is passed through the avoidance hole 641 on the first limiting block 64 and the second through hole on the second fixed block 32 and threadedly connected with the second threaded hole on the slide 13 to fix the second fixed block 32 on the slide 13.

[0065] Then start the second motor 681 to rotate the second rotating shaft 683 and make the second limiting block 67 parallel to the connecting block 65; the second rotating shaft 683 drives the adjusting block 91 to move, and the adjusting block 91 drives the second supporting block 83 to move in the direction away from the second fixed block 32, so that the positioning block 85 is no longer located in the second oil inlet hole 321 of the second fixed block 32, and the second spring 86 is in a normal state.

[0066] Finally, the first cylinder 61 and the second cylinder 63 are activated to move the connecting block 65 out of the receiving groove 111 of the main body 11, and the first limiting block 64 is moved to one side of the assembly table 5 without affecting the main body 11 being taken out of the placement groove of the assembly table 5. The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
