The opening and closing of the second jaw and the fourth jaw are controlled by sector cam blocks arranged around the first turret and the turntable feeding mechanism to clamp or loosen the air bag / semi-finished workpiece; in addition, sector limit plates are also arranged around the first turret and the turntable feeding mechanism to prevent the air bag or semi-finished workpiece from falling;

[0050] (6) Compression springs are provided on both the first pressing push rod and the first upward pushing push rod, so that the first pressing push rod and the first upward pushing push rod are in close fit with the cam groove of the first cam ring and the cam surface of the second cam ring respectively, improving the assembly accuracy;

[0051] (7) The double turret nozzle assembly assembling device provided by the present invention can completely realize the integrated pipeline operation of feeding, assembling, and discharging of the main body plug, the air bag, and the long tube.

That is, when the main plug 1 is clamped, the air bag 2 is also in the clamped state. Similarly, when the first jaw 1013-1 releases the main plug 1, the air bag 2 is also released by the second jaw 1023-1.

[0097] The second jaw 1023-1 is a spring jaw containing a first Y-shaped jaw body 1023-2 and a third spring 1023-3. The middle part of the first Y-shaped jaw body 1023-2 is horizontally rotatably installed on the lower surface of the third turntable 1004. The front end of the first Y-shaped jaw body 1023-2 is provided with a long and a short bifurcated part. The end of the first long bifurcated part 1023-5 is provided with a third roller 1023-4 for cooperating with the first sector cam block 1004-2. In the rotation direction, the first long bifurcated part 1023-5 is located in front of the first short bifurcated part 1023-6. The rear end of the first Y-shaped jaw body 1023-2 is connected to the third spring 1023-3, and the other end of the third spring 1023-3 is installed inside the third turntable 1004. When the third turntable 1004 rotates to the position where the second jaw 1023-1 contacts the first sector cam block 1004-2, the second jaw 1023-1 opens, and when the third turntable 1004 rotates to the position where the second jaw 1023-1 leaves the first sector cam block 1004-2, the second jaw 1023-1 closes to clamp the air bag 2 in the opening groove 1004-1 of the third turntable. At this time, the air bag 2 is squeezed by the first short bifurcated part 1023-6 relative to the outside of the opening groove 1004-1 of the third turntable to be clamped and fixed at the opening groove 1004-1 of the third turntable. The first sector limit plate 1004-3 plays a circumferential limiting role to prevent the air bag 2 from falling during the rotation of the turret.

[0098] In the mold closing position area of the first turret 1000, the first cam ring 1011 is recessed downward and the second cam ring 1021 protrudes upward, so that the first downward pressing push rod 1012-1 floats downward and presses tightly on the upper end surface of the main body plug 1 clamped by the first jaw 1013-1, and the first upward pushing push rod 1022-1 floats upward to push the air bag 2 clamped by the second jaw 1023-1 upward and insert it into the main body plug 1 to form a semi-finished workpiece 4.

[0099] As Figure 11 and Figure 12As shown in the figure, a ninth turntable 1006 is fixedly installed on the first turret main body 1001. An electromagnetic control mechanism 1030 is provided on the first turret main body 1001 to control the opening and closing of each first gripper 1013-1 respectively. The electromagnetic control mechanism 1030 includes a sector magnet 1031 and a number of solenoid valves 1032 circumferentially arranged on the ninth turntable 1006. The sector magnet 1031 is statically installed on the first turret main body 1001, and the solenoid valves 1032 on the first turret main body 1001 are in one-to-one correspondence and electrically connected to the first grippers 1013-1 in the axial direction. When the solenoid valve 1032 rotates to the area of the sector magnet 1031, the solenoid valve 1032 senses the magnetic field and closes the corresponding first gripper 1013-1. When the solenoid valve 1032 leaves the area of the sector magnet 1031, the solenoid valve 1032 opens the corresponding first gripper 1013-1. It should be noted that the mold closing position area of the first turret 1000 is located within the axial projection area of the sector magnet 1031 to ensure that the first grippers 1013-1 are always in the closed state when the first turret 1000 closes the mold.

[0100] In addition, as Figure 7 and Figure 9 shown, the first turret 1000 is connected with a main body plug feeding device 1040 and an air bag conveying device 1050. The main body plug feeding device 1040 feeds the main body plug 1 into the second turntable opening groove 1003-1 in front of the sector magnet 1031, and the air bag conveying device 1050 is connected to the starting position of the first cam block 1004-2. The air bag conveying device 1050 conveys the air bag 2 and transfers it into the third turntable opening groove 1004-1 at the rear side of the first cam block 1004-2 (as Figure 8 shown).

[0101] It should be noted that the front side and the rear side in this article are determined by the rotation direction of the turret.

[0102] The second turret 2000

[0103] As Figure 20-23 shown, the second turret 2000 is provided with a second turret main body 2001. A fifth turntable 2002, a sixth turntable (not shown in the figure), a seventh turntable 2004, and an eighth turntable 2005 are successively arranged above and below the second turret main body 2001.

[0104] A workpiece clamping and pressing mechanism 2010 and a long pipe clamping and lifting mechanism 2020 are installed above and below the second turret main body 2001. The workpiece clamping and pressing mechanism 2010 and the long pipe clamping and lifting mechanism 2020 are respectively used to clamp the semi-finished workpiece 4 and the long pipe 3. The long pipe clamping and lifting mechanism 2020 jacks up the long pipe 3 to insert it into the semi-finished workpiece 4 to form a nozzle assembly 5. And while the long pipe clamping and lifting mechanism 2020 jacks up, the workpiece clamping and pressing mechanism 2010 presses on the upper end surface of the semi-finished workpiece 4.

[0105] The workpiece clamping and pressing mechanism 2010 is successively provided with a third cam ring 2011, a second pressing mechanism 2012 and a third clamping mechanism 2013 from top to bottom. The third cam ring 2011 is fixedly installed on the second turret body 2001. The second pressing mechanism 2012 and the third clamping mechanism 2013 are respectively installed on the fifth turntable 2002 and the sixth turntable. The second pressing mechanism 2012 and the third clamping mechanism 2013 respectively include a plurality of second pressing push rods 2012-1 and a plurality of third clamping jaws 2013-1 circumferentially arranged on the fifth turntable 2002 and the sixth turntable. There is a circle of sixth turntable opening grooves along the outer edge of the sixth turntable for supporting the semi-finished workpiece 4, and the lower half of the semi-finished workpiece 4 is clamped by the third clamping jaws 2013-1 located on the lower surface of the sixth turntable. During the rotation of the second pressing push rod 2012-1 with the second turret body 2001, it cooperates with the third cam ring 2011 to float up and down.

[0106] The long pipe clamping and upward pushing mechanism 2020 is successively provided with a fourth cam ring 2021, a second upward pushing mechanism 2022 and a fourth clamping mechanism 2023 from bottom to top. The fourth cam ring 2021 is fixedly installed on the second turret body 2001. The second upward pushing mechanism 2022 is installed on the eighth turntable 2005. The second upward pushing mechanism 2022 includes a plurality of second upward pushing push rods 2022-1 circumferentially arranged on the eighth turntable 2005. During the rotation of the second upward pushing push rod 2022-1 with the second turret body 2001, it cooperates with the fourth cam ring 2021 to float up and down. The fourth clamping mechanism 2023 includes a circle of seventh turntable opening grooves 2004-1 arranged along the outer edge of the seventh turntable 2004 for supporting the long pipe 3, and a second sector-shaped limiting plate 2023-1 fixedly arranged at intervals along a part of the outer edge of the seventh turntable for preventing the long pipe 3 in the seventh turntable opening grooves 2004-1 from falling.

[0107] In the present invention, the workpiece clamping and pressing mechanism 2010 on the second turret 2000 has basically the same structure as the main body plug clamping and pressing mechanism 1010 of the first turret 1000. The difference is that the main body plug clamping and pressing mechanism 1010 is used for clamping and pressing the main body plug 1, while the workpiece clamping and pressing mechanism 2010 is used for clamping and pressing the semi-finished workpiece 4. However, the top of the pressed semi-finished workpiece 4 is still the main body plug 1. Therefore, the main body plug clamping and pressing mechanism 1010 of the first turret 1000 can be directly applied to the workpiece clamping and pressing mechanism 2010 of the second turret 2000, and the structural description of the workpiece clamping and pressing mechanism 2010 will not be elaborated here.

[0108] Similarly, the long pipe clamping and upward pushing mechanism 2020 on the second turret 2000 also has basically the same structure as the air bag clamping and pushing mechanism 1020 of the first turret 1000. Therefore, the structural description of the long pipe clamping and upward pushing mechanism 2020 will not be elaborated either.

[0109] Similarly, the second turret 2000 is also equipped with the same ninth turntable 1006 and electromagnetic control mechanism 1030 as those on the first turret 1000, and their structures and functions are exactly the same. The opening and closing of the third jaw 2013-1 are controlled by the solenoid valve 1032 on the second turret 2000 sweeping across the sector magnet 1031, thereby clamping or releasing the semi-finished workpiece 4. Among them, the mold closing positions of the second turret 2000 are all located within the axial projection area of the sector magnet 1031 to ensure that when the second turret 2000 closes the mold, the third jaw 2013-1 is always in a closed state. 1) When the solenoid valve 1032 rotates to the area of the sector magnet 1031, the solenoid valve 1032 senses the magnetic field and closes the corresponding third jaw 2013-1. When the solenoid valve 1032 leaves the area of the sector magnet 1031, the solenoid valve 1032 opens the corresponding third jaw 2013-1.

[0110] The mold closing principle of the second turret 2000 is the same as that of the first turret 1000. Within the mold closing position area of the second turret 2000, the third cam ring 2011 is recessed downward and the fourth cam ring 2021 protrudes upward, so that the second downward pressing push rod 2012-1 floats downward and presses tightly on the upper end surface of the semi-finished workpiece 4 clamped by the third jaw 2013-1. And at the same time, the second upward pushing push rod 2022-1 floats upward to push the long tube 3 in the opening groove 2004-1 of the seventh turntable upward and insert it into the semi-finished workpiece 4 to form the nozzle assembly 5.

[0111] In addition, as Figure 7 and Figure 9 shown, the second turret 2000 is also connected with a long tube conveying device 2040 and a material taking device 2050. The long tube conveying device 2040 sends the long tube 3 into the opening groove 2004-1 of the seventh turntable, and the material taking device 2050 takes away the nozzle assembly 5 assembled on the second turret 2000.

[0112] As Figure 23 shown, the material taking device 2050 is provided with a Y-shaped guide plate 2051. A purging device is provided at the end of the Y-shaped guide plate 2051. The gas is ejected through the purging device to make the nozzle assembly 5 on the turntable shake. During the rotation of the second turret, it cooperates with the Y-shaped guide plate 2051, and the nozzle assembly 5 is conveyed to the discharge track 2052 through the Y-shaped guide plate 2051 to complete the discharging.

[0113] Turntable material transfer mechanism 3000

[0114] As Figure 10As shown in the figure, the turntable material transfer mechanism 3000 is provided with a tenth turntable 3001. A number of tenth turntable opening slots are provided on the outer edge of the tenth turntable 3001. A number of fourth clamping jaws 3004 are installed on the tenth turntable 3001. The rotational directions of the tenth turntable 3001 and the first turret 1000 and the second turret 2000 on both sides are opposite to each other.

[0115] A second sector cam block 3002 and a third sector limiting plate 3003 are fixedly installed statically around the tenth turntable 3001. A turntable material transfer mechanism feed port and a turntable material transfer mechanism discharge port are provided between the two ends of the second sector cam block 3002 and the third sector limiting plate 3003. The turntable material transfer mechanism feed port is connected to the first turret discharge port, and the turntable material transfer mechanism discharge port is connected to the second turret 2000.

[0116] A number of tenth turntable opening slots are provided on the outer edge of the tenth turntable 3001, such as Figure 24 As shown in the figure, the fourth clamping jaw 3004 is a spring clamping jaw including a second Y-shaped claw body 3004-1 and a fourth spring 3004-6. The middle part of the second Y-shaped claw body 3004-1 is horizontally rotatably installed on the tenth turntable 3001. The front end of the second Y-shaped claw body 3004-1 is provided with a long and a short bifurcated part. The second long bifurcated part 3004-2 and the second short bifurcated part 3004-3 are flush in height. The end of the second long bifurcated part 3004-2 is provided with a fourth roller 3004-4 for cooperating with the second sector cam block 3002. In the rotational direction, the second long bifurcated part 3004-2 is located in front of the second short bifurcated part 3004-3. An auxiliary clamping arm 3004-5 with a different height from the second short bifurcated part 3004-3 is fixedly installed on the second long bifurcated part 3004-2. The other end of the auxiliary clamping arm 3004-5 extends towards the second short bifurcated part 3004-3. The rear end of the second Y-shaped claw body 3004-1 is connected to the fourth spring 3004-6, and the other end of the fourth spring 3004-6 is installed on the tenth turntable 3001 near the axis of the second Y-shaped claw body 3004-1.

[0117] Such as Figure 25 As shown in the figure, a first clamping notch 3004-31 is provided on the other side of the second short bifurcated part 3004-3 relative to the second long bifurcated part 3004-2, and the end of the auxiliary clamping arm 3004-5 is provided with a second clamping notch 3004-51 on the same side as the first clamping notch 3004-31. In the rotational direction, both the first clamping notch 3004-31 and the second clamping notch 3004-51 are located on the front side of the second Y-shaped claw body 3004-1. By simultaneously pressing different heights of the main plug 1 with the second short bifurcated part 3004-3 and the auxiliary clamping arm 3004-5, the clamping effect is made more stable.

[0118] When the tenth turntable 3001 rotates to the position where the fourth roller 3004-4 contacts the second sector cam block 3002, the fourth jaw 3004 is in the open state; when the tenth turntable 3001 rotates to the position where the fourth roller 3004-4 leaves the second sector cam block 3002, the fourth spring 3004-6 pulls the second Y-shaped jaw body 3004-1 to rotate and reset, and the short bifurcated part 3004-3 rotates towards the opening groove of the tenth turntable to clamp the semi-finished workpiece 4 in the opening groove of the tenth turntable. At this time, the main plug 1 of the semi-finished workpiece 4 is simultaneously squeezed by the second short bifurcated part 3004-3 and the auxiliary clamping arm 3004-5 relative to the outside of the opening groove of the tenth turntable to be clamped and fixed at the opening groove of the tenth turntable.

[0119] The structure and working principle of the fourth jaw 3004 are basically the same as those of the second jaw 1023-1 on the first turret, and specific reference can be made to the relevant description of the second jaw 1023-1 above.

[0120] In the rotation direction, the fourth jaw 3004 sequentially passes through the discharge port of the first turret, the third sector limit plate 3003, the feed port of the second turret, and the second sector cam block 3002 in a cycle.

[0121] The working process of the present invention is briefly described as follows:

[0122] 1) The main plug 1 and the air bag 2 are respectively conveyed to the first turret 1000 and clamped by the first jaw 1013-1 and the second jaw 1023-1 respectively. Taking the conveyance of the air bag 2 as an example for illustration: The air bag conveying device 1050 sends the air bag 2 to the feed port of the first turret (the feed port of the first turret is located behind the end of the first sector cam block 1004-2). When the second jaw 1023-1 cooperates with the first sector cam block 1004-2, the second jaw 1023-1 is in the open state. Along with the rotation of the turret, the second jaw 1023-1 is separated from the first sector cam block 1004-2, and under the action of the third spring 1023-3, the second jaw 1023-1 resets and clamps the air bag 2 in the third turntable opening groove 1004-1.

[0123] When the first turret 1000 rotates to the mold closing position, the first downward pressing push rod 1012-1 floats downward and presses tightly on the upper end surface of the main plug 1, and at the same time, the first upward pushing push rod 1022-1 floats upward to push the air bag 2 upward and insert it into the main plug 1 to form a semi-finished workpiece 4.

[0124] 2) The semi-finished workpiece 4 on the first turret 1000 is taken away by the turntable material transfer mechanism 3000 and transferred to the second turret 2000. On the second turret 2000, the semi-finished workpiece 4 is clamped by the third jaw 2013-1, and the long tube 3 is sent into the seventh turntable opening groove 2004-1 of the second turret 2000 by the long tube conveying device 2040.

[0125] 3) When the second turret 2000 rotates to the mold closing position, the second downward pressing push rod 2012-1 floats downward and presses tightly against the upper end surface of the semi-finished workpiece 4. At the same time, the second upward pushing push rod 2022-1 floats upward to push the long tube 3 upward and insert it into the semi-finished workpiece 4 to form the nozzle assembly 5.

[0126] 4) As the second turret 2000 continues to rotate, when the nozzle assembly 5 rotates to the position of the material taking device 2050, the Y-shaped guide plate 2051 of the material taking device 2050 continuously blows gas, so that the nozzle assembly 5 detaches from the turret and flows to the discharge track 2052 under the action of the Y-shaped guide plate 2051 to finally complete the discharging.

[0127] In steps 1 and 3, when the solenoid valve 1032 on the first turret 1000 or the second turret 2000 rotates to the area of the sector magnet 1031, the solenoid valve 1032 senses the magnetic field and closes the corresponding first jaw 1013-1 or the third jaw 2013-1. When the solenoid valve 1032 of the first turret 1000 leaves the area of the sector magnet 1031, the solenoid valve 1032 opens the corresponding first jaw 1013-1, and the semi-finished workpiece 4 on the first turret 1000 is transferred away by the rotary table material transfer mechanism 3000; when the solenoid valve 1032 of the second turret 2000 leaves the area of the sector magnet 1031, the solenoid valve 1032 opens the corresponding third jaw 2013-1 so that the material taking device 2050 can take away the assembled nozzle assembly 5 on the second turret 2000.

[0128] The preferred embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the above specific embodiments, and the devices and structures not described in detail should be understood to be implemented in a common manner in the art; any person skilled in the art can make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes, without departing from the scope of the technical solution of the present invention, which does not affect the essence of the present invention.
