[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] Depend on Figures 1 to 5 It is given that the utility model includes an L-shaped device base 1, a convex workpiece table 2 that can rotate at equal angles is installed on the top of the middle part of the L-shaped device base 1, and a plurality of workpiece placement grooves 3 are opened in a ring at equal distances on the upper part of the convex workpiece table 2, a hydraulic telescopic cylinder 4 is installed on the top of the L-shaped device base 1, and a riveting punch head 5 is installed on the telescopic end of the hydraulic telescopic cylinder 4, and the riveting punch head 5 is located directly above one of the workpiece placement grooves 3, and a fixed block 6 is fixedly installed on the telescopic end of the hydraulic telescopic cylinder 4, and a slide rod 20 is fixedly installed on the top of the middle part of the L-shaped device base 1, and one side of the fixed block 6 is slidably sleeved on the surface of the slide rod 20 so that the fixed block 6 can be stably lifted and lowered, and a transmission plate 7 is fixedly installed on the bottom of the fixed block 6, and the convex workpiece table 2 can be rotated and adjusted by a single reciprocating up and down movement of the transmission plate 7.

[0021] A horizontal inner groove 8 is provided in the middle of the L-shaped device base 1, and an adjusting shaft 9 is rotatably installed inside the inner groove 8 and fixedly connected to the axis center of the bottom of the convex workpiece table 2. Balls 10 in contact with the bottom of the convex workpiece table 2 are equidistantly installed in a ring on the top of the middle part of the L-shaped device base 1. The adjusting shaft 9 is located at the bottom of the inner groove 8 and is fixedly connected to a worm gear 11. A vertical inner groove 12 connected to the horizontal inner groove 8 is provided in the middle of the L-shaped device base 1. A worm 13 meshing with the worm gear 11 is rotatably connected between the inside of the horizontal inner groove 8 and the vertical inner groove 12. A ratchet 14 is fixedly installed on the surface of the worm 13 located inside the vertical inner groove 12, thereby effectively adjusting the rotation of the convex workpiece table 2;

[0022] When the ratchet 14 rotates, it drives the worm 13 to rotate the worm wheel 11. The rotation of the worm wheel 11 drives the adjustment shaft 9 and the convex workpiece table 2 to rotate. The rotation of the convex workpiece table 2 drives the workpiece placement slot 3 to rotate and change its position.

[0023] A ratchet 15 connected to the ratchet 14 is rotatably installed inside the vertical inner groove 12, and a return spring A16 is fixedly installed between the middle part of the ratchet 15 and the inside of the vertical inner groove 12. A one-way toggle block 17 matching the ratchet 14 is equidistantly installed on the side of the transmission plate 7 close to the ratchet 14. The lower part of the one-way toggle block 17 facing the end of the ratchet 14 is a sloped structure. Mounting grooves 18 are equidistantly opened on one side of the transmission plate 7. The one-way toggle block 17 is movably inserted into the inside of the mounting groove 18, and a return spring B19 is fixedly connected between one end of the one-way toggle block 17 and the inside of the mounting groove 18, thereby effectively adjusting the one-way transmission of the worm 13;

[0024] By starting the hydraulic telescopic cylinder 4 to extend, the riveting punch 5, the fixed block 6 and the transmission plate 7 are driven to move downward. The downward movement of the riveting punch 5 will move toward the workpiece placement slot 3 aligned with it, so that the riveting punch 5 performs a riveting operation on the workpiece placed inside the workpiece placement slot 3;

[0025] The downward movement of the transmission plate 7 drives the one-way toggle block 17 to move downward. The downward movement of the one-way toggle block 17 contacts the ratchet 14 through the inclined surface structure at its end. The ratchet 14 cannot rotate due to the restriction of the ratchet teeth 15. Therefore, the one-way toggle block 17 is squeezed and moves to the installation groove 18, compressing the return spring B19 until all the one-way toggle blocks 17 move downward to the bottom of the ratchet 14 and are located inside the vertical inner groove 12.

[0026] After the riveting punch 5 completes riveting the workpiece inside the workpiece placement slot 3, the contraction of the hydraulic telescopic cylinder 4 will drive the riveting punch 5, the fixed block 6 and the transmission plate 7 to move upward. When the riveting punch 5 is removed from the inside of the workpiece placement slot 3, the upward movement of the transmission plate 7 will drive the one-way toggle block 17 to toggle and rotate the ratchet 14 in one direction, and the one-way rotation of the ratchet 14 will drive the worm 13 to perform one-way rotation adjustment; and the upward movement of all the one-way toggle blocks 17 will adjust the rotation angle of the convex workpiece table 2, thereby alternating the positions of all the workpiece placement slots 3; and the continuous telescopic adjustment of the hydraulic telescopic cylinder 4 can enable continuous riveting operations.

[0027] This multi-station riveting device has the function of multi-station continuous riveting. It drives the stations to perform unidirectional equal-angle rotation adjustment through the expansion and contraction of the hydraulic cylinder to replace the positions of multiple stations, thereby effectively ensuring the continuity of the riveting process, and effectively ensuring the speed and efficiency of the riveting process. In addition, this multi-station riveting device has a simple structural design, is easy to use, and has stable and reliable processing. Its performance can meet the use requirements of riveting processing.
