It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0024] Example

[0025] like Figs. 1 to 3 As shown, a parts assembly mechanism with an interlocking structure is used for assembling an arc-shaped workpiece 1. The assembly mechanism is provided with a support 2, and the support 2 is provided with a first card holder 21 and a second card holder 22. The first card holder 21 and the second card holder 22 are rotatably disposed on the support 2. The first card holder 21 is provided with a first card groove 211, and the second card holder 22 is provided with a second card groove 221. The first card groove 211 and the second card groove 221 are arranged opposite to each other, and the arc-shaped workpiece 1 is disposed between the first card groove 211 and the second card groove 221.

[0026] The arc-shaped workpiece 1 is positioned between the first slot 211 and the second slot 221, which can quickly and accurately position the arc-shaped workpiece 1 and improve assembly efficiency. The first tray 21 and the second tray 22 clamp the arc-shaped workpiece 1 inward from both sides, making full use of the large tension that the arc surface of the arc-shaped workpiece 1 can withstand, ensuring that the arc-shaped workpiece 1 is not damaged, reducing the defect rate of the product, and ensuring the quality of the assembled arc-shaped workpiece.

[0027] The upper groove surfaces of the first slot 211 and the second slot 221 are respectively adapted to the arc surface shape of the corresponding side of the arc-shaped workpiece 1. In this embodiment, the upper groove surface of the first slot 211 is adapted to the shape of the left arc surface of the arc-shaped workpiece 1, and the upper groove surface of the second slot 221 is adapted to the shape of the right arc surface of the arc-shaped workpiece 1.

[0028] The lower surfaces of the first slot 211 and the second slot 221 are also smooth curved surfaces. The width of the first slot 211 and the second slot 221 gradually increases from the inside to the outside, so that the arc-shaped workpiece 1 can smoothly enter the first slot 211 and the second slot 221.

[0029] The support 2 is also provided with a first support 23, a second support 24 and a pushing mechanism 25. The pushing mechanism 25 is provided with a pushing track 251 and a pushing seat 252. The pushing seat 252 is slidably provided on the pushing track 251. The first support 23 is linked with the pushing seat 252. The first card holder 21 is provided on the first support 23 and the second card holder 22 is provided on the second support 24.

[0030] The pushing mechanism 25 pushes the pushing seat 252 to move, which can cause the first support 23 to move closer to or further away from the second support 24, thereby adjusting the distance between the first clip 21 and the second clip 22; the arc-shaped workpiece 1 enters between the first clip 211 and the second clip 221, the distance between the first clip 21 and the second clip 22 becomes shorter, and the arc-shaped workpiece 1 can be clamped; the distance between the first clip 21 and the second clip 22 becomes longer, and the arc-shaped workpiece 1 can be smoothly unloaded from between the first clip 211 and the second clip 221.

[0031] The first support 23 is provided with a first rotating mechanism 231. The first rotating mechanism 231 is provided with a first rotating shaft 2311 and a first rotating sleeve 2312. The first rotating sleeve 2312 is sleeved on the first rotating shaft 2311. The first card holder 21 is linked with the first rotating sleeve 2312. The first card holder 21 can rotate smoothly, so that the upper groove surface of the first card slot 211 can completely fit on the arc surface of the arc workpiece 1, protecting the arc workpiece 1.

[0032] The first rotating mechanism 23 is also provided with a first torsion spring 2313. The first torsion spring 2313 is sleeved on the first rotating shaft 2311. The inner side of the first card holder 21 is against the lever arm of the first torsion spring 2313 and presses the first torsion spring 2313 tightly. Under the action of the first torsion spring 2313, the first card holder 21 can automatically rotate outward to reset.

[0033] The second support 24 is provided with a second rotating mechanism 241. The second rotating mechanism 241 is provided with a second rotating shaft 2411 and a second rotating sleeve 2412. The second rotating sleeve 2412 is sleeved on the second rotating shaft 2411. The second card holder 22 is linked with the second rotating sleeve 2412, so that the upper groove surface of the second card slot 221 can be completely attached to the arc surface of the arc workpiece 1, protecting the arc workpiece 1.

[0034] The second rotating mechanism 241 is also provided with a second torsion spring 2413. The second torsion spring 2413 is sleeved on the second rotating shaft 2412. The inner side of the second card holder 22 is against the lever arm of the second torsion spring 2413 and presses the second torsion spring 2413 tightly. Under the action of the second torsion spring 2413, the second card holder 22 can automatically rotate outward to reset.

[0035] The assembling mechanism is further provided with a pressing mechanism 3, which is provided with a punching cylinder 31 and a punching seat 32. The punching seat 32 is connected with the piston of the punching cylinder 31, and is arranged above the supporting seat 2.

[0036] The lower end of the punching seat 32 is provided with a mechanical clamping jaw 321, which can grab the accessory of the arc-shaped workpiece 1 and press the arc-shaped workpiece 1 on the supporting seat 2 under the action of the pressing mechanism 3, so as to complete the assembly of the arc-shaped workpiece 1.
