Figure 23The observation groove 2632 is located above the punctator taking groove 2631. After the punctator is misaligned, the punctator lifting cylinder 2618 drives the punctator turning electric clamps 268 to descend. When the top of the punctator lifting cylinder 2618 touches the first lifting buffer 2619, the punctator turning electric clamps 268 stop descending.

When the punctator lifting limiting column 2621 touches the second lifting buffer 2620, the punctator turning electric clamps 268 stop moving upwards. Then the punctator turning cylinder 262 drives the turning cylinder connecting block 2629 and the punctator rack 2627 to move towards the punctator flat conveying assembly 23. The punctator rack 2627 drives the punctator turning gear 2624 to rotate. The punctator turning gear 2624 drives the turning fixed plate 264 to rotate through the driving turning shaft, so that the four sets of punctator turning electric clamps 268 drive the clamped punctator to turn. The driven turning shaft and the punctator turning swing rod 266 are also driven to rotate. Before turning, the punctator turning swing rod 266 is in contact with one of the punctator rotation buffers 267. After turning, the punctator turning swing rod 266 rotates to contact the other punctator rotation buffer 267. At this time, the punctator has rotated 180 degrees. After turning, the punctator is turned upside down.

The two groove walls of the nut material channel groove 3321 close to one end of the nut vibration disc assembly 32 are arranged in an inclined manner and form a nut material channel groove opening 3327, which facilitates the movement of the nut from the nut vibration disc assembly 32 to the nut material channel groove 3321. The two adjacent nut material channel grooves 3321 form a nut material channel convex strip 3322, which is provided with a plurality of nut material channel mounting holes 3323 and a plurality of nut material channel strip-shaped holes 3324. Screws pass through the nut material channel mounting holes 3323 and fix the nut material channel plate 332 on the nut straight vibration connecting plate.

The nut detection sensor 386 is used for detecting whether the nut is correctly sleeved on the puncture device, as Figure 36As shown, the two nuts on the right are installed incorrectly, the two nuts on the left are installed correctly, the bottom of the correctly installed nut is in a suspended state, and the position of the nut detection sensor 386 sensing end is below the correctly installed nut. When the nut detection sensor 386 senses the nut, it indicates that the nut is installed incorrectly, so the next step cannot be performed, and the system alarms to inform the human to handle it.

[0151] In the above technical solution: as Figure 37 As shown, the nut installation mechanism 39 includes a nut installation bottom plate 391 fixed on the support frame 10 and a lower pressing material base 3914 fixed on the ring rail pad plate 19. The nut installation bottom plate 391 is fixed with a pressing material back plate 393, and the pressing material back plate 393 is fixed with a second pressing material reinforcing rib 3911 between the nut installation bottom plate 391. The lower pressing material base 3914 is fixed with a pressing material column 3913, and the pressing material column 3913 is fixed with an upper pressing material base 3912.

[0152] In the above technical solution: the bottom of the pressing material top plate 392 is fixed with a pressing material cylinder 394, and the piston rod of the pressing material cylinder 394 is connected with a nut installation pressing block 395. The nut installation pressing block 395 includes a cylindrical fixed part 3951 and a cylindrical pressing material part 3952. The fixed part 3951 is provided with a pressing block installation hole 3953, and the hole wall of the pressing block installation hole 3953 is provided with a thread. The piston rod of the pressing material cylinder 394 is threadedly installed with the fixed part 3951 through a shaft coupling. The pressing material part 3952 is provided with a pressing hole 3954 in communication with the pressing installation hole 3953. As shown, Figure 38 The diameter of the fixed part 3951 is greater than the diameter of the pressing material part 3952, and the hole diameter of the pressing hole 3954 is greater than the hole diameter of the pressing block installation hole 3953. The jig 15 drives the puncture device and the nut to move to the nut pressing mechanism 39, and the puncture device is located directly below the pressing hole 3954. When pressing, the pressing material cylinder 394 drives the nut installation pressing block 395 to move downward, the part of the nut exposed by the puncture device gradually enters the pressing hole 3954, and the nut is driven by the pressing material part 3952 to move downward until the nut is installed in place.

[0153] In the above technical solution: a pressing connecting block 3915 is fixed on the pressing column 3913; a pressing sensor fixing plate 3916 is fixed on one side of the pressing connecting block 3915; a pressing sensor 396 is fixed at the bottom of the pressing sensor fixing plate 3916; and a reset sensor 3918 is fixed at the top of the pressing sensor fixing plate 3916. A pressing sensing plate 397 is also connected to the piston rod of the pressing cylinder 394. The pressing sensing plate 397 is driven up and down by the pressing cylinder 394. Both the pressing sensor 396 and the reset sensor 3918 are responsible for sensing the pressing sensing plate 397. The pressing cylinder 394 drives the nut mounting block 395 and the nut to move downwards. When the pressing sensor 396 senses the pressing sensor 397, it indicates that the nut is installed in place. Then the pressing cylinder 394 drives the nut mounting block 395 to move upwards. When the reset sensor 3918 senses the pressing sensor 397, it indicates that the nut mounting block 395 has completely disengaged from the nut and piercing device on the fixture 15. At this time, the fixture 15 can continue to move.

[0154] In the above technical solution: a precision pressure regulating valve 399 is also fixed on the pressure back plate 393. The precision pressure regulating valve 399 controls the output force of the pressure cylinder to prevent damage to the nut.

[0155] In the above technical solution: a pressing lifting solenoid valve 3917 is also fixed on the pressing back plate 393, and the pressing lifting solenoid valve 3917 is used to control the movement of the pressing cylinder 394.

[0156] In the above technical solution: the material support assembly 18 is located below the nut mounting block 395. When the nut mounting block 395 presses the nut on the fixture 15, the pressure exerted by the nut mounting block 395 on the fixture 15 may damage the ring rail fixture device 1 due to the relatively large force applied during pressing. Therefore, the material support assembly 18 is provided to support the fixture 15. During the support process, the bottom of the support top plate 158 on the fixture 15 contacts the cam bearing follower 186. The downward pressing force of the nut mounting block 395 causes the upper fixture block 151 and the lower fixture block 152 to move down a certain distance. At the same time, the oilless bushing 155 is pressed downward by the third limiting ring 1527, and the support spring 157 is compressed. The material support assembly 18 and the support top plate 158 support the downward movement of the fixture 15. After the material is pressed, the pressure of the nut mounting block 395 on the fixture 5 disappears, the elastic force of the support spring 157 is released, and the upper fixture block 151 and lower fixture block 152 return to their original positions. The oil-free bushing 155 and the second guide post 154 guide the downward movement of the fixture 15. The use of a rolling cam bearing follower 186 in contact with the support top plate 158 reduces the friction between the material support assembly 18 and the fixture 15, facilitating the movement of the fixture 15 after the material is pressed.

[0157] The technical scheme is as follows: the sealing ring feeding device 4 comprises a sealing ring transmission mechanism, a sealing ring receiving mechanism 42, a sealing ring moving mechanism 43, a second puncture device guiding mechanism 44, a sealing ring installing mechanism 46 and a sealing ring detecting mechanism 45.

During the above process, the second puncture device guiding mechanism 44 positions the puncture device on the jig 15. The sealing ring moving mechanism 43 clamps the sealing ring on the sealing ring receiving mechanism 42 and drives the sealing ring to move above the puncture device on the jig 15, then the sealing ring moving mechanism 43 releases the sealing ring, and the sealing ring is sleeved on the puncture device. The sealing ring installing mechanism 46 is responsible for installing the sealing ring on the puncture device in place, and the sealing ring detecting mechanism 45 is responsible for detecting whether the puncture device is correctly sleeved with a sealing ring. The sealing ring feeding device 4 further comprises a sealing ring receiving box 47. When the sealing ring moving mechanism 43 does not clamp the sealing ring, the sealing ring will fall into the sealing ring receiving box 47. The sealing ring receiving box 47 can recycle the accidentally fallen sealing ring, preventing material waste. Two pairs of angle limiting blocks 471 are arranged on the bottom of the sealing ring receiving box 47 to prevent the sealing ring receiving box 47 from moving. The sealing ring transmission mechanism, the sealing ring receiving mechanism 42, the sealing ring moving mechanism 43, the sealing ring installing mechanism 46, the sealing ring detecting mechanism 45 and the sealing ring receiving box 47 are all installed on the support frame 10, and the second puncture device guiding mechanism 44 is installed on the ring rail pad plate 19.

[0158] The technical scheme is as follows: Figure 39 , 40As shown in FIG. 41, the sealing ring conveying mechanism comprises a sealing ring vibrating disc base plate 411, a sealing ring vibrating disc 413 and a sealing ring linear conveying assembly 41 arranged on the sealing ring vibrating disc base plate 411, and the sealing ring vibrating disc base plate 411 is fixed on the support rack 10 through a sealing ring support rod 412. The sealing ring vibrating disc 413 rotates counterclockwise. The sealing ring linear conveying assembly 41 comprises a sealing ring linear feeder 415 and a linear vibration fixed plate 414, the linear vibration fixed plate 414 is fixed on the sealing ring vibrating disc base plate 411, four linear vibration support columns 4112 are fixed on the four corners of the linear vibration fixed plate 414, and the sealing ring linear feeder 415 is installed on the linear vibration support columns 4112. A sealing ring linear vibration connecting plate is installed on the sealing ring linear feeder 415, and a sealing ring material channel plate 416 is installed on the sealing ring linear vibration connecting plate. The sealing ring material channel plate 416 comprises a narrow part 4161, a wide part 4162 and an inclined part 4163 connecting the narrow part 4161 and the wide part 4162, and the end of the narrow part 4161 is tightly attached to the discharge port of the sealing ring vibrating disc 413. Four sealing ring material channel grooves are formed on the sealing ring material channel plate 416, the four sealing ring material channel grooves comprise two first sealing ring material channel grooves 4164 and two second sealing ring material channel grooves 4169, the two second sealing ring material channel grooves 4169 are located between the two first sealing ring material channel grooves 4164, the two first sealing ring material channel grooves 4164 are respectively arranged in parallel with the two side edges of the sealing ring material channel plate 416, the two second sealing ring material channel grooves 4169 have the same bending trend as the first sealing ring material channel grooves 4164, but the bending angle is smaller than that of the first sealing ring material channel grooves 4164, that is, the length of the second sealing ring material channel grooves 4169 is shorter than that of the first sealing ring material channel grooves 4164. A sealing ring material channel convex strip 4165 is formed between two adjacent sealing ring material channel grooves. A plurality of sealing ring material channel mounting holes 4166 and a plurality of sealing ring material channel strip-shaped holes 4167 are formed on the sealing ring material channel convex strip 4165, screws pass through the sealing ring material channel mounting holes 4166 and fix the sealing ring material channel plate 416 on the sealing ring linear vibration connecting plate, and the sealing ring material channel strip-shaped holes 4167 reduce the weight of the sealing ring material channel plate 416. A sealing ring induction hole 4168 is formed on the groove bottom of the sealing ring material channel groove close to the sealing ring vibrating disc 413. The two groove walls of the sealing ring material channel groove close to the sealing ring vibrating disc 413 are arranged in an inclined manner and form a sealing ring material channel groove opening 4160, which facilitates the movement of the sealing ring from the sealing ring vibrating disc 413 to the sealing ring material channel groove.

The sealing ring fullness sensors 418 are responsible for sensing the sealing ring sensing hole 4168 on the sealing ring material channel plate 416. When the sealing ring fullness sensors 418 sense the sealing ring, the sealing ring vibration disc 413 stops vibrating and feeding, which reduces the noise and energy consumption caused by the sealing ring vibration disc 413 without affecting the production capacity. When the sealing ring fullness sensors 418 sense the sealing ring sensing hole 4168, the sealing ring vibration disc 413 continues to vibrate and feed. The sealing ring sensing hole 4168 is set to prevent the sealing ring fullness sensors 418 from sensing and transmitting incorrect instructions. Because the condition that the sealing ring fullness sensors 418 do not sense the sealing ring is very likely to be that the sealing ring fullness sensors 418 happen to sense the hollow part on the sealing ring. At this time, the sealing ring fullness sensors 418 transmit the instruction of the sealing ring vibration disc 413 to continue vibrating and feeding, which cannot better reduce the noise and energy consumption caused by the sealing ring vibration disc 413. The sealing ring transmission mechanism further comprises two groups of electrostatic elimination fans 4113, which are respectively arranged on the sealing ring vibration disc 413 and the sealing ring flat conveying assembly 41. A large number of sealing rings contact with each other during the sealing ring feeding process, which is easy to generate static electricity.
