[0028] Example

[0029] Reference Figures 1-4 This embodiment of the present invention provides an automatic riveting device for seamless pins, comprising:

[0030] The drive mechanism 200 includes a bracket 210, a servo motor 220 for driving operations, a shaft seat 230 fixedly installed at the output end of the servo motor 220, and a reciprocating rod 240 that reciprocates in conjunction with the shaft seat 230.

[0031] The processing mechanism 100 includes a base 110, a frame 120 fixedly installed on the top of the base 110, a fixed seat 130 fixedly installed on the top of the frame 120, and a guide groove 140 formed on the top of the fixed seat 130.

[0032] And a cleaning mechanism 300 that works in conjunction with the drive mechanism 200 to achieve the cleaning effect;

[0033] The cleaning mechanism 300 includes a fixing block 310 fixedly installed on the top of the base 110, a slide bar 320 for guiding the cleaning angle, and a sliding sleeve 330 movably sleeved on the outside of the slide bar 320.

[0034] The coordinated operation of the drive mechanism 200 and the cleaning mechanism 300 effectively solves the problem of the impact of residual foreign matter, dust or debris after workpiece processing on the accuracy of subsequent assembly or riveting.

[0035] Specifically, the cleaning mechanism 300 also includes a positioning clamp 340 fixedly installed on the outside of the sliding sleeve 330, a cleaning plate 350 movably installed in the inner cavity of the positioning clamp 340 for cleaning work, and a guide assembly 360 for limiting the cleaning position of the cleaning plate 350.

[0036] The design of the fixing block 310 and the sliding rod 320 allows the sliding sleeve 330 to slide flexibly to adapt to cleaning needs at different angles. The cooperation between the positioning clamp 340 and the sweeping plate 350 ensures the comprehensiveness and accuracy of the cleaning work.

[0037] Furthermore, the guide assembly 360 includes a limiting piece 361 rotatably mounted on the inner wall of the guide groove 140, a pull strip 362 fixedly connected to the outer side of the cleaning plate 350, a guide piece 363 fixedly mounted on the outer side of the limiting piece 361, and a rotating rod 364 rotatably mounted in the center of the inner cavity of the limiting piece 361, the end of the rotating rod 364 being rotatably connected to the inner wall of the guide groove 140.

[0038] Among them, the guide assembly 360 achieves multi-angle cleaning of the sweeping plate 350 through the linkage of the limiting plate 361, the pull bar 362, the guide plate 363 and the rotating rod 364, which further improves the cleaning effect. The connection between the pull bar 362 and the limiting cylinder 271 enables the sweeping mechanism 300 to work in coordination with the drive mechanism 200 to achieve efficient reciprocating motion.

[0039] Preferably, the drive mechanism 200 further includes a vertical rod 250 hinged to the end of the reciprocating rod 240, a connecting plate 260 fixedly installed at the end of the vertical rod 250, and a telescopic buffer assembly 270 disposed at the bottom of the connecting plate 260.

[0040] The servo motor 220 provides stable and adjustable power output, ensuring the motion accuracy and efficiency of the reciprocating rod 240. The design of the bearing seat 230 allows the output end of the servo motor 220 to be stably fixed, avoiding shaking during the movement. The hinged design between the reciprocating rod 240 and the vertical rod 250 allows the drive mechanism 200 to flexibly adapt to the motion requirements of the sweeping mechanism 300, enabling the pull bar 362 to perform lateral reciprocating motion during vertical reciprocating motion, thereby achieving the sweeping effect of the sweeping plate 350, improving the suction effect and preventing debris accumulation.

[0041] It should be noted that the telescopic buffer assembly 270 includes a limiting cylinder 271 fixedly installed at the bottom of the connecting plate 260, a groove 272 opened in the inner cavity of the limiting cylinder 271, and a return spring 273 movably sleeved in the inner cavity of the groove 272. The telescopic buffer assembly 270 also includes a movable rod 274 movably sleeved in the inner cavity of the return spring 273, and a buffer contact 245 fixedly installed at the end of the movable rod 274.

[0042] The design of the limiting cylinder 271 and the groove 272 enables the return spring 273 and the movable rod 274 to work stably and provides a good buffering effect. The buffer contact 275 provides a buffering effect against the impact and wear when the vertical rod 250 moves downward, thus improving durability and stability.

[0043] Furthermore, the processing mechanism 100 also includes a ventilation pipe head 150 fixedly installed on the outside of the base 110 for connecting to an external dust collection pipe, a pneumatic cylinder 160 fixedly installed on the top of the fixed seat 130, a riveting head 170 provided at the bottom of the fixed seat 130, and a worktable plate 180 fixedly installed on the outside of the frame 120.

[0044] The base 110 and frame 120 provide stable support, ensuring the stability of the equipment during operation. The design of the fixed seat 130 and guide groove 140 enables the pneumatic cylinder 160 and riveting head 170 to be accurately positioned and operated, improving the accuracy and consistency of riveting. The ventilation pipe head 150 can be used with an external dust collector to remove dust, effectively removing dust and debris generated during processing. The worktable 180 provides a stable operating platform for the workpiece, further improving processing efficiency.

[0045] Furthermore, one end of the pull bar 362 is fixedly connected to one end of the limiting cylinder 271, and the installation positions of the two guide plates 363 are provided with outlets to realize the reciprocating motion of the pull bar 362.

[0046] The design of the limiting piece 361 and the guide piece 363 enables the pull strip 362 to move stably, ensuring the precise positioning of the sweeping plate 350.

[0047] When in use, the servo motor 220 starts and drives the reciprocating rod 240 to reciprocate through the bearing 230. The reciprocating rod 240 drives the vertical rod 250 and the connecting plate 260 to move, which in turn drives the sliding sleeve 330 of the cleaning mechanism 300 to slide along the sliding rod 320. Under the guidance of the positioning clamp 340 and the guide assembly 360, the cleaning plate 350 performs multi-angle cleaning, effectively removing foreign objects, dust and debris from the surface of the workpiece.

[0048] Meanwhile, the pneumatic cylinder 160 drives the riveting head 170 to perform riveting operations on the workpiece, ensuring a tight connection between the pin and the workpiece; the ventilation pipe head 150 removes dust and debris generated during processing through an external dust extraction pipe, keeping the working environment clean; the telescopic buffer assembly 270 provides a buffering effect when the vertical rod 250 moves downward during the movement, reducing the impact and wear during equipment operation and ensuring stable operation of the equipment.

[0049] In summary, the coordinated operation of the drive mechanism 200, processing mechanism 100, and cleaning mechanism 300 effectively solves the problem of residual foreign matter, dust, or debris after workpiece processing affecting the accuracy of subsequent assembly or riveting. The drive mechanism 200, through the cooperation of the servo motor 220 and the reciprocating rod 240, achieves precise reciprocating motion of the cleaning mechanism 300, simulating the cleaning effect of manual operation and significantly improving cleaning efficiency and quality. The processing mechanism 100, through the cooperation of the pneumatic cylinder 160 and the riveting head 170, ensures a tight connection between the pin and the workpiece, while the design of the ventilation duct head 150 effectively removes dust, avoiding pollution of the working environment and protecting the health of operators. The cleaning mechanism 300, through the linkage of the slide rod 320, the sliding sleeve 330, and the guide assembly 360, achieves multi-angle cleaning of the cleaning plate 350, further improving the comprehensiveness and accuracy of cleaning. The design of the telescopic buffer assembly 270 reduces impact and wear during equipment operation, improving the durability and stability of the equipment.
