Description

Technical Field

[0001] This invention belongs to the field of sealing ring assembly technology, and specifically relates to an automated assembly equipment for screw plugs. Background Technology

[0002] There is a need to seal specific cavities in mechanical equipment to keep the liquid or gas medium inside the cavity within a specified range and ensure the normal operation of the equipment. Sealing rings are widely used and come in many types. Among them, the most common type is a screw plug seal formed by welding bolts and sealing rings to achieve the sealing function and prevent leakage.

[0003] Before welding the sealing ring and bolt, the bolt face must be facing up. The worker needs to fit the sealing ring onto the bolt's convex ring. During the fitting process, the bolt face and back face are different, so the bolts need to be manually inspected first. Bolts with the back face facing up need to be flipped so that the front face is facing up before the sealing ring is fitted. The manual selection and fitting of bolts on the assembly line makes the production time longer and the production efficiency lower. Summary of the Invention

[0033] Please see Figure 5 and Figure 6 A riveting mechanism 30 is provided on one side of the feeding mechanism 20. A third base 31 is provided at the bottom of the riveting mechanism 30, and a third guide rail 311 is mounted on it.

The bolt 111 and the sealing ring 121 are connected by an ultrasonic generator on the ultrasonic mounting mechanism 40 to prevent the sealing ring 111 from being worn out. After the bolt 111 and the sealing ring 121 are connected, the assembled bolt 111 is transported out through the discharge chute 15 by the discharge robot.

[0034] The working principle and usage process of this invention are as follows: First, the bolts 111 are transported by the first vibrating plate 11. When the bolts 111 are transported to the screening tank 222, because the screening tank 222 is convex, some of the bolts 111 with their reverse sides facing up will be screened by the screening tank 222 and fall back to the first vibrating plate 11 under the vibration of the first base 21. The bolts 111 with their front sides facing up continue to be transported forward. When the bolts 111 are transported to the stop block 224, the first cylinder rod 232 drives the cover plate 235 along a... As guide rail 233 moves, when sensor 237 on the left side of cover plate 235 contacts stop 224, slot 236 on the left side of cover plate 235 coincides with transport rail 221, and transport rail 221 transports bolt 111 into slot 236 on the left side of cover plate 235. When sensor 237 on the right side of cover plate 235 contacts stop 224, slot 236 on the right side of cover plate 235 coincides with transport rail 221, and bolt 111 falls into cover plate. When all the bolts 111 have fallen into the second slot 236 on the right side of the cover plate 235, the second cylinder rod 25 drives the second slider 242 to move. When passing the first telescopic rod 26, the suction cup 262 falls, and the air cylinder 261 picks up the bolts 111 and transports them into the assembly plate 14 on the rotating plate 13. When the bolts 111 are placed in the first slot 141, the button 142 is pressed to control the rotating plate 13 to rotate and transport the assembly plate 14 to the second vibrating plate 12. The feeding mechanism 20 transports the sealing ring 121 onto the bolt 111. Then, the rotating disk 13 continues to rotate, driving the assembly disk 14 to below the riveting mechanism 30. The sealing ring 121 and the bolt 111 in the assembly disk 14 are pressed together by the second telescopic rod 33, the pressure plate 35 and the pressure block 351 on the riveting mechanism 30. Finally, the sealing ring 121 and the bolt 111 are assembled by the ultrasonic installation mechanism 40. The assembled bolt 111 is transported out through the discharge chute 15 by the discharge mechanism, completing the assembly.
