[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, 6, 7, and 8, this utility model provides a technical solution: a rotary automatic riveting machine, comprising: a worktable 1, which is a box with a disc fixed to its top; a rotating ring 2 rotatably mounted on the outside of the disc at the top of the worktable 1, and a driving part for driving the rotating ring 2 to rotate at a fixed angle inside the worktable 1; a combination fixture equidistantly placed on the top of the rotating ring 2, the combination fixture including a fixed block 4 fixed to the top of the rotating ring 2 and a moving block 5 slidably mounted on the end of the fixed block 4; a dual-axis cylinder 19 fixed to the top of the worktable 1 for driving the workpiece on the top of the fixed block 4 and the workpiece on the moving block 5 to be combined vertically and correspondingly; a material handling mechanism placed on the top of the worktable 1, the material handling mechanism including a pneumatic chuck 18 for clamping materials and a moving part for driving the pneumatic chuck 18 to rise, fall, and move horizontally; and a servo electric cylinder 9 fixed to the top of the worktable 1, the output end of which is fixedly connected to a riveting head 10.

[0028] It should be noted that a PLC controller is provided in this embodiment. The controller controls the drive unit to drive the rotating ring 2 to rotate clockwise. During the rotation, the material handling mechanism sequentially installs the parts at the positions corresponding to the fixed block 4 and the moving block 5. When the combined fixture moves to the position corresponding to the dual-axis cylinder 19, under the action of the infrared sensor, the controller controls the dual-axis cylinder 19 to push the moving block 5 towards the end of the fixed block 4, so that the parts on the moving block 5 are placed below the workpiece on the fixed block 4. The rotating ring 2 rotates to place the workpiece below the servo cylinder 9. The servo cylinder 9 drives the riveting head 10 to rivet the workpiece downward. After the riveting is completed, the rotating ring 2 rotates it to the unloading position. The material handling mechanism removes it through the pneumatic chuck 18. The rotating ring 2 continues to rotate, and the corresponding material handling mechanism loads the parts again in sequence.

[0029] In one embodiment, the drive unit includes a servo motor fixed inside the worktable 1 and a spur gear set 3. The spur gear set 3 includes a gear ring fixed to the rotating ring 2, and a pinion gear meshing with the outer side of the gear ring. The pinion gear is fixedly connected to the output end of the servo motor.

[0030] It should be noted that in this embodiment, an encoder is installed at the end of the servo motor. The encoder is electrically connected to the controller via a cable. The servo motor drives the gear ring to rotate via a pinion, which in turn drives the rotating ring 2 to rotate. The rotating ring 2 drives the combined fixture to rotate, so that the combined fixture performs corresponding processing with the upper and lower mechanisms and the servo electric cylinder 9.

[0031] In one embodiment, the top of the fixed block 4 is provided with a positioning groove 7 for mounting a workpiece, and a sliding rod 6 is slidably connected inside the fixed block 4. One end of the sliding rod 6 is fixedly connected to the moving block 5, and a positioning post 8 is fixedly connected to the top of the moving block 5. When the fixed block 4 and the moving block 5 are combined, the positioning post 8 corresponds to the positioning groove 7.

[0032] It should be noted that in this embodiment, two protrusions are fixedly connected to one side of the moving block 5, the positioning post 8 is fixedly connected to the top of the protrusions, and two sliding grooves that cooperate with the protrusions are opened in the middle of the fixed block 4. The positioning groove 7 is located on one side of the sliding groove. The accessory is placed on the outside of the positioning post 8 by the material picking mechanism, and then the middle workpiece is sleeved on the workpiece on the outside of the positioning post 8. Then the L-shaped workpiece to be pressed is placed inside the positioning groove 7. The moving block 5 is driven to fit with the fixed block 4 by the dual-axis cylinder 19, and the sliding rod 6 slides inside the fixed block 4, so that the workpiece inside the positioning groove 7 is located directly above the workpiece of the positioning post 8, which facilitates riveting processing from top to bottom.

[0033] In one embodiment, the material handling mechanism includes a loading section three, a loading section two, a loading section one, and a unloading section arranged in a counterclockwise order. The loading section three is located on the side close to the dual-axis cylinder one 19. A feeding trough connected to a vibratory feeder is provided below the loading section three, the loading section two, and the loading section one. A proximity switch is provided at the end of the feeding trough for detecting the position of the pneumatic chuck 18 and the workpiece. A guide trough for receiving material is provided below the unloading section. The loading section three, the loading section two, the loading section one, and the unloading section all include a support two 14 fixedly connected to the worktable 1. A lifting seat 17 is vertically slidably connected to the outside of the support two 14. A cylinder three 16 for driving the lifting seat 17 to rise and fall is fixedly connected to the top of the support two 14. A pneumatic chuck 18 is slidably connected to the outside of the lifting seat 17. A cylinder two 15 for driving the pneumatic chuck 18 to slide is fixedly connected to one end of the lifting seat 17.

[0034] It should be noted that in this embodiment, the rotating ring 2 rotates clockwise. During this period, the first, second, and third feeding parts pick up materials from the corresponding conveying troughs and install them at the positions corresponding to the fixed block 4 and the moving block 5. When picking up, the second cylinder 15 drives the pneumatic chuck 18 to move laterally, and the third cylinder 16 drives the pneumatic chuck 18 to move vertically through the lifting seat 17, thereby realizing lifting and lateral movement and sending the workpiece inside the conveying trough to the combined fixture.

[0035] In one embodiment, the servo cylinder 9 is located on the side near the unloading section. A bracket 11 is provided on one side of the servo cylinder 9. The bracket 11 is fixedly connected to the worktable 1. A pre-tightening head 13 is vertically slidably connected to the outside of the bracket 11. A cylinder 12 that drives the pre-tightening head 13 is fixedly connected to the top of the bracket 11.

[0036] It should be noted that, in this embodiment, when the workpiece is installed in the positions corresponding to the fixed block 4 or the moving block 5 in sequence, when the combined fixture rotates to correspond with the dual-axis cylinder 19, the dual-axis cylinder 19 pushes the moving block 5 to contact and combine with the fixed block 4, so that it rotates to the position of the corresponding bracket 11. An infrared sensor is installed on one side of the bracket 11. When the infrared sensor detects the combined fixture, the cylinder 12 drives the pre-tightening head 13 to move downward. The pre-tightening head 13 performs preliminary clamping and positioning of the combined workpiece. After the cylinder 12 is reset, the workpiece rotates to the bottom of the servo electric cylinder 9. The servo electric cylinder 9 drives the riveting head 10 to move downward to perform pressing processing on the workpiece.

[0037] In one embodiment, a dual-axis cylinder 21 is fixedly connected to the top of the workbench 1 disc and at the position corresponding to the unloading part, for driving the fixed block 4 and the moving block 5 to separate. A dual-axis cylinder 20 is fixedly connected to the top of the workbench 1 and between the loading part and the unloading part. The height of the dual-axis cylinder 20 is higher than the combined fixture. A metal rod for separating the fixed block 4 and the moving block 5 is fixedly connected to the output end of the dual-axis cylinder 20, for separating the fixed block 4 and the moving block 5.

[0038] It should be noted that after the workpiece is pressed in this embodiment, it rotates to the bottom of the unloading part. The double-axis cylinder 21 extends to squeeze the sliding rod 6, causing the sliding rod 6 to drive the moving block 5 to separate from the fixed block 4. The unloading part clamps the processed workpiece through the pneumatic chuck 18 and places it in the guide groove through lifting and lateral movement. Under the guidance of the guide groove, it slides into the collection box. After the material is picked up, under the action of the timer, the rotating ring 2 continues to drive the separated fixture to rotate. When the separated combined fixture corresponds to the double-axis cylinder 20, the metal rod is located between the fixed block 4 and the moving block 5. The double-axis cylinder 20 retracts to drive the metal rod to move the moving block 5. After the move, the double-axis cylinder 20 extends to make the metal rod located between the fixed block 4 and the moving block 5. By moving it, the moving block 5 is located in the preset position, which facilitates the positioning column 8 to cooperate with the loading part.
