[0015] Compared with the prior art, the advantages of this utility model are as follows: 1. In this utility model, the riveting workpiece is placed on the workpiece fixing component and the riveting workpiece is limited. The turntable is driven to rotate clockwise by the cam divider, which drives the workpiece fixing component to pass through the conveying component, the pressing component and the detection and unloading mechanism in sequence. Thus, the riveting workpiece on the workpiece fixing component completes the feeding of the riveting stud, the pressing of the riveting workpiece and the riveting stud, and the detection and sorting of the riveting workpiece after riveting in sequence. During the feeding of the riveting stud, the riveting stud is moved to the preset position by the automatic feeding component, and the riveting stud at the preset position is clamped and transported to the riveting workpiece by the conveying component, thus completing the automatic feeding of the riveting stud. 2. In this utility model, the riveting workpiece is placed on the support plate 1, and the riveting workpiece is limited by the limit block 1 and the limit block 2. When the cam divider drives the turntable, thereby driving the support plate 1 to rotate to the conveying component, the automatic feeding component moves the riveting stud to the preset position, the conveying component clamps the riveting stud and places it in the hole opened on the riveting workpiece, and then the turntable drives the support plate 1 to rotate to the pressing component for riveting. The buffer spring 1 provides buffering, and finally it moves to the detection and discharge mechanism for detection and classification collection. 3. In this utility model, when the output end of the vibrator moves the riveting stud through the slot on the second fixed plate to abut against the rotating disk, the servo motor drives the rotating disk to rotate, thereby connecting the limiting hole on the rotating disk with the slot on the rotating disk. At this time, the riveting stud enters the limiting hole through the output end of the vibrator, and the lower end of the riveting stud is located between the second fixed plate and the first fixed frame. At this time, the laser emitted by the first laser sensor is blocked by the lower end of the riveting stud, thereby causing the first laser sensor to send a signal to the PLC controller, which then controls the servo motor to drive the rotating disk to rotate, so that the next limiting hole connects with the slot on the rotating disk. The above operation is repeated until there are riveting studs in all the limiting holes, and the servo motor drives the rotating disk to rotate to... When the distribution position of the limiting hole corresponds to the hole opened on the workpiece, the linear module one drives the moving plate one to move directly above the fixed plate two. At this time, the cylinder one drives the moving plate one to move downward. With the cooperation of the fixed frame two, the clamping cylinder one on the fixed frame three moves to the pressing stud on the limiting hole. The clamping cylinder one clamps and removes the pressing stud. The moving plate one is driven to rise by the cylinder one. The linear module one drives the fixed frame two, and the moving plate one moves directly above the pressing workpiece on the turntable. At this time, the cylinder one drives the moving plate one, and then drives the clamping cylinder one to move downward to the pressing workpiece. At this time, the clamping cylinder one releases the clamping of the pressing stud, so that the pressing stud falls into the opening of the pressing workpiece, thereby realizing the automatic feeding of the pressing stud. 4. In this utility model, when the turntable moves the riveting workpiece to directly below the second support plate, the cylinder drives the third fixing plate to move downward, which in turn drives the second support plate to move downward, thereby driving the pressure rod and the pressure block to move downward. This causes the pressure rod to first abut against the riveting screw on the riveting workpiece, and as the cylinder moves downward, the pressure block abuts against the riveting workpiece. At this time, the second buffer spring sleeved on the pressure rod cannot be compressed, so that the pressure rod completes the riveting of the riveting screw. This achieves the fixation of the riveting workpiece when riveting the riveting screw on the riveting workpiece, ensuring accurate riveting position. At the same time, the service life of the equipment can be improved under the action of the second buffer spring. 5. In this utility model, when the turntable moves the riveting workpiece to directly below the clamping cylinder two, the linear module two drives the fixed plate five and the moving plate two, thereby causing the clamping cylinders two at both ends of the moving plate two to rise and fall synchronously. This allows the left clamping cylinder two to clamp the riveting workpiece on the fixed plate one via the clamping block, while the right clamping cylinder two clamps the riveting workpiece detected on the mounting frame. When the left side is being unloaded, cylinder two drives the clamping cylinder two, which in turn drives the buffer plate downwards. At this time, cylinder three drives the push plate, which in turn drives the push rod upwards, allowing the push rod to pass through the holes in the support plate one and the fixed plate one, thereby pushing the riveting screw pressed onto the riveting workpiece. This causes the riveting workpiece to move upwards, freeing it from the limitation of the limiting block one and the limiting block two, while simultaneously being clamped by the clamping block. Under the action of the buffer plate and the buffer spring three, the upward-moving riveting workpiece is buffered. The buffer plate abuts against the riveted workpiece, allowing for better clamping. During right-side inspection, cylinder four moves the inspection plate upward, causing the riveting studs on the workpiece to engage with the inspection plate. If laser sensor two is blocked, it indicates the riveting studs cannot be inserted into the inspection plate, resulting in a failed riveting test; otherwise, it is successful. Right-side clamping cylinder two moves the clamping block to hold the riveted workpiece, and under the action of linear module two, the workpiece is moved onto the belt conveyor. The PLC controller controls the belt conveyor's movement. Qualified products are conveyed normally to the next process flow, while unqualified products are pushed out of the belt conveyor by cylinder five controlled by the PLC controller, causing the workpiece to fall into the collection box. This process enables the inspection of the riveting studs on the workpiece and the classification and collection of the riveted workpieces. Attached Figure Description

The standard parts feeding assembly 3 includes an automatic feeding assembly 31 and a conveying assembly 32; both the automatic feeding assembly 31 and the conveying assembly 32 are mounted on the multi-station turntable assembly 1.

[0022] In this utility model, the riveting workpiece 6 is placed on the workpiece fixing component 2 and the riveting workpiece 6 is limited. The turntable 12 is driven to rotate clockwise by the cam divider 13, which drives the workpiece fixing component 2 to pass through the conveying component 32, the pressing component 4 and the detection and unloading mechanism 5 in sequence. Thus, the riveting workpiece 6 on the workpiece fixing component 2 completes the feeding of the riveting stud, the pressing of the riveting workpiece 6 and the riveting stud, and the detection and sorting of the riveting workpiece 6 after riveting. During the feeding of the riveting stud, the automatic feeding component 31 moves the riveting stud to the preset position, and the conveying component 32 clamps and transports the riveting stud at the preset position to the riveting workpiece 6, thus completing the automatic feeding of the riveting stud.

[0023] The workpiece fixing assembly 2 includes a fixing support assembly 21 and a limiting assembly 22. The fixing support assembly 21 is mounted on the turntable 12, and the limiting assembly 22 is connected to the fixing support assembly 21.

[0024] The fixed support assembly 21 includes a support plate 211, a limiting rod 212, a buffer spring 213, and a fixing plate 214. The support plate 211 is fixedly installed on the turntable 12.

The buffer spring 213 is sleeved on the limiting rod 212, and both ends of the buffer spring 213 are fixedly connected to the support plate 211 and the fixing plate 214, respectively.

[0025] The limiting component 22 includes a first limiting block 221 and a second limiting block 222. Two first limiting blocks 221 are symmetrically fixedly installed at the left and right ends of the first fixing plate 214, and two sets of second limiting blocks 222 are fixedly installed at the front and rear ends of the first fixing plate 214.

[0026] In this embodiment, the turntable 12 is an eight-position turntable that rotates 45 degrees clockwise each time.

[0027] In this embodiment, both the support plate 211 and the fixing plate 214 are provided with clearance holes of the same size as the press-fit stud.

[0028] In this utility model, the riveting workpiece 6 is placed on the support plate 211 and is limited by the limiting block 221 and the limiting block 222. When the cam divider 13 drives the turntable 12, thereby driving the support plate 211 to rotate to the conveying component 32, the automatic feeding component 31 moves the riveting stud to the preset position. The conveying component 32 clamps the riveting stud and places it in the hole opened on the riveting workpiece 6. Then, the turntable 12 drives the support plate 211 to rotate to the pressing component 4 for riveting. The buffer spring 213 provides buffering. Finally, it moves to the detection and discharge mechanism 5 for detection and classification collection.

The first laser sensor 317 is located between the second fixed plate 314 and the first fixed frame 312 and is fixedly installed on the first fixed frame 312. Multiple limiting holes 316 are provided on the rotating disk 315.

[0030] The conveying assembly 32 includes a gantry frame 321, a linear module 322, a fixed frame 323, a cylinder 324, a moving plate 325, a clamping cylinder 326, and a fixed frame 327. The gantry frame 321 is fixedly installed on the left end of the machine base 11. The linear module 322 is fixedly installed on the gantry frame 321, and the output end of the linear module 322 is fixedly connected to the fixed frame 323.

[0034] In this embodiment, a PLC controller (not shown in the figure) is fixedly installed on the machine base 11.

[0035] In this embodiment, both the laser sensor 317 and the servo motor 313 are electrically connected to the PLC controller.

[0036] In this invention, when the output end of the vibrator 311 moves the riveting stud through the slot on the second fixing plate 314 to abut against the rotating disk 315, the servo motor 313 drives the rotating disk 315 to rotate, thereby connecting the limiting hole 316 on the rotating disk 315 with the slot on the rotating disk 315. At this time, the riveting stud enters the limiting hole 316 through the output end of the vibrator 311, and the lower end of the riveting stud is located between the second fixing plate 314 and the first fixing bracket 312. At this time, the laser emitted by the first laser sensor 317 is blocked by the lower end of the riveting stud, thereby causing the first laser sensor 317 to send a signal to the PLC controller, causing the PLC controller to control the servo motor 313 to drive the rotating disk 315 to rotate, so that the next limiting hole 316 connects with the slot on the rotating disk 315. The above operation is repeated. When there are riveting studs on all the limiting holes 316, the servo motor 313 drives the rotating disk 315 to rotate to the limit. When the positions of holes 316 correspond to the holes on the workpiece, the linear module 322 moves the movable plate 325 to directly above the fixed plate 314. At this time, the cylinder 324 moves the movable plate 325 downward. With the cooperation of the fixed frame 323, the clamping cylinder 326 on the fixed frame 327 moves to the riveting stud on the limiting hole 316. The clamping cylinder 326 clamps and removes the riveting stud, and the cylinder 324... 4. The moving plate 325 is raised, and the linear module 322 drives the fixed frame 323 to move the moving plate 325 to directly above the riveting workpiece 6 on the turntable 12. At this time, the cylinder 324 drives the moving plate 325, which in turn drives the clamping cylinder 326 to move downward to the riveting workpiece 6. At this time, the clamping cylinder 326 releases the clamp on the riveting stud, so that the riveting stud falls into the opening of the riveting workpiece 6, thereby realizing the automatic feeding of the riveting stud.

[0037] The pressing assembly 4 includes a support frame 3 41, a hydraulic cylinder 42, a limiting rod 2 43, a fixing plate 3 44, a buffer spring 2 45, a pressure rod 46, a support plate 2 47, and a pressure block 48.

The buffer spring 2 45 is sleeved on the pressure rod 46, and both ends of the buffer spring 2 45 are fixedly connected to the fixing plate 3 44 and the support plate 2 47 respectively. The pressure block 48 is fixedly installed on the support plate 2 47.

[0038] In this invention, when the turntable 12 moves the riveting workpiece 6 directly below the support plate 47, the cylinder 42 drives the fixing plate 44 to move downward, which in turn drives the support plate 47 to move downward, thereby driving the pressure rod 46 and the pressure block 48 to move downward. This causes the pressure rod 46 to first abut against the riveting screw on the riveting workpiece 6, and as the cylinder 42 moves downward, the pressure block 48 abuts against the riveting workpiece 6. At this time, the buffer spring 45 sleeved on the pressure rod 46 cannot be compressed, allowing the pressure rod 46 to complete the riveting of the riveting screw. This achieves the fixation of the riveting workpiece 6 when riveting the riveting screw, ensuring accurate riveting position. At the same time, the buffer spring 45 can improve the service life of the equipment.

The collection box 555 for collecting defective products is fixedly installed on the machine base 11, and the collection box 555 is located in front of the belt conveyor 551.

[0045] In this embodiment, clamping grooves for clamping blocks 522 are provided at both ends of the mounting bracket 541.

[0046] In this embodiment, a discharge port for discharging materials is provided on the front side of the belt conveyor 551.

[0047] In this embodiment, clamping cylinders 326, 324, 516, 521, 531, 543, and 553 are all connected to an external air supply device.

[0048] In this embodiment, the hydraulic cylinder 42 is connected to an external oil supply device.

[0049] In this embodiment, the external air supply device, the external oil supply device, the belt conveyor 551, the linear module 1 322, and the linear module 2 512 are all connected to the PLC controller.

[0050] In this utility model, when the turntable 12 moves the riveted workpiece 6 to directly below the clamping cylinder 521, the linear module 512 drives the fixed plate 513 and the moving plate 514, thereby causing the clamping cylinders 521 at both ends of the moving plate 514 to rise and fall synchronously. This allows the left clamping cylinder 521 to clamp the riveted workpiece 6 on the fixed plate 214 via the clamping block 522, while the right clamping cylinder 521 clamps the riveted workpiece 6 detected on the mounting bracket 541. When the left side is being unloaded, the cylinder 516... The clamping cylinder 521 drives the buffer plate 524 to move downwards. At this time, the cylinder 531 drives the push plate 532, which in turn drives the push rod 533 to move upwards. This causes the push rod 533 to pass through the holes in the support plate 211 and the fixing plate 214, thereby pushing the rivet screw pressed against the rivet workpiece 6. This causes the rivet workpiece 6 to move upwards, so that it is no longer limited by the limiting block 221 and the limiting block 222, but can be clamped by the clamping block 522. Under the action of the buffer plate 524 and the buffer spring 523, it moves upwards. The moving riveting workpiece 6 is buffered, causing the buffer plate 524 to abut against the riveting workpiece 6. This allows for better clamping of the riveting workpiece 6. During right-side inspection, the cylinder 543 moves the detection plate 542 upward, allowing the riveting studs on the riveting workpiece 6 to engage with the detection plate 542. If the laser sensor 547 is blocked, it indicates that the riveting studs on the riveting workpiece 6 cannot engage with the detection plate 542, and the riveting is unqualified. Conversely, if the laser sensor 547 is unblocked, the riveting is qualified. The right-side clamping cylinder 521 then moves the clamping block. 522 clamps the riveted workpiece 6 and moves it onto the belt conveyor 551 under the action of the linear module 512. The PLC controller controls the movement of the belt conveyor 551. Qualified products are normally conveyed to the next process flow, while unqualified products are pushed out of the belt conveyor 551 by the cylinder 553 controlled by the PLC controller, so that the riveted workpiece 6 falls into the collection box 555. This realizes the detection of the riveted studs on the riveted workpiece 6 and the classification and collection of the riveted workpiece 6.
