[0005] Preferably, the lower end surface of the forming guide sleeve is connected to a forming head guide sleeve, a buffer pad and a forming head are provided in the inner hole, a discharging ring is provided between the inner positioning head and the forming head, and a compression spring is provided between the discharging ring and the forming rod.

[0006] Preferably, a positioning rod is provided in the positioning guide sleeve, a cap support is provided in the positioning rod, and a fixing pin is provided in the pin holes of the cap support and the positioning turntable.

[0007] Preferably, the forming head can be designed into a required shape according to actual requirements.

[0008] The beneficial effect of the present invention is: realizing the continuous full-automatic assembly of the two components of the soft ring and the cap body, greatly improving the production efficiency and product quality, reducing the labor intensity and production cost, effectively guaranteeing the product supply, and improving the market competitiveness of the enterprise.

[0014] For better understanding and implementation, the present invention will be further described below with reference to the accompanying drawings:

[0015] A structure for continuous assembly of a soft-ring aluminum-plastic combined water cover with a boss, mainly including a forming cam 1, a forming turntable 4, a positioning turntable 13, and a positioning cam 17. It is characterized in that a forming guide sleeve 5 is provided on the forming turntable 4, a forming rod 3 is provided in the inner hole of the forming guide sleeve 5, an inner positioning head 9 is provided at the lower end of the forming rod 3, the upper end of the inner positioning head 9 is connected to the forming pin 2, and the guide wheel of the forming pin 2 is in the cam groove of the forming cam 1; a material receiving tray 12 is provided on the upper end surface of the positioning turntable 13, a positioning guide sleeve 16 is provided on the lower end surface, the cam groove of the positioning cam 17 is provided with the guide wheel of the positioning pin 18, and the other end of the positioning pin 18 is connected to the positioning rod 19.

[0016] Preferably, the lower end surface of the forming guide sleeve 5 is connected to the forming head guide sleeve 10, a buffer pad 7 and a forming head 11 are arranged in the inner hole, a unloading ring 8 is arranged between the inner positioning head 9 and the forming head 11, and a compression spring 6 is arranged between the unloading ring 8 and the forming rod 3.

[0017] Preferably, a positioning rod 19 is arranged in the positioning guide sleeve 16, a cover holder 14 is arranged in the positioning rod 19, and a fixed pin 15 is arranged in the pin holes of the cover holder 14 and the positioning turntable 13.

[0018] Preferably, the forming head 11 can be designed into a required shape according to actual requirements.

[0019] According to the above implementation mode, the specific working process is analyzed as follows:

[0020] After the soft ring 20 enters the material receiving tray 12, the forming cam 1 drives the forming pin 2 to press down the forming rod 3, and the inner positioning head 9 positions and grabs the soft ring 20.

[0021] After the cover body 21 enters the material receiving tray 12, under the drive of the forming cam 1, the forming rod 3 sleevs the soft ring 20 on the cover body 21. After that, the forming cam 1 temporarily maintains the stroke unchanged.

[0022] Continuing to rotate, the positioning cam 17 toggles the positioning pin 18 to push up the positioning rod 19 until the bottom edge of the boss of the cover body 21.

[0023] After reaching the position, simultaneously, the positioning cam 17 pushes up the positioning rod 19, and the forming cam 1 drives the forming rod 3 to move upward by the same set distance.

[0024] After reaching the set distance, the positioning cam 17 temporarily maintains the stroke unchanged, and the forming cam 1 drives the forming rod 3 to move upward by the set distance.

[0025] After reaching the set distance, the positioning cam 17 continues to push up the positioning rod 19 to the set distance to complete the forming and assembly. During the assembly process, the buffer pad 7 can effectively eliminate the hard assembly force and avoid damaging the finished product.

[0026] After forming, the forming rod 3 and the positioning rod 19 move downward and reset simultaneously. During the downward movement, the spring 6 presses the unloading ring 8 to push the finished product out of the forming head 11. Under the action of the cover support 14, the cover body 21 is pushed out of the positioning rod 19.

[0027] The entire structure continues to operate to the discharging position, and the product is pushed away from the material receiving tray 12. Since it is continuous feeding and continuous rotation, this structure realizes continuous automated operation.
