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.

[0024] Please see Figures 1-6In this embodiment of the present invention, a riveting fixture with a rotating structure includes a rotating base 2, a riveting turntable 1, and a hydraulic cylinder 10. A stepper motor 22 is disposed at the bottom center of the rotating base 2, and the riveting turntable 1 is rotatably connected to the top of the rotating base 2. A connecting turntable 19 is disposed at the bottom center of the riveting turntable 1, and the connecting turntable 19 is fixedly connected to the output end of the stepper motor 22. Six rivet placement holes 14 are evenly distributed on the outer ring of the top of the rotating base 2. A fan-shaped rotation clearance groove 16 is disposed at the bottom of the rivet turntable 1 below the rivet placement holes 14. A bottom locking bolt 17 is threadedly connected to the rotation clearance groove 16, and a rotating support plate 3 is rotatably connected to the rotation clearance groove 16 around the bottom locking bolt 17. An electromagnet 8 is bolted to the top of the rotating support plate 3. The electromagnet 8 can firmly position the workpiece to be processed by magnetic attraction, preventing the rotating base 2 from sliding when rotating. A telescopic support plate 4 is slidably connected to the rotating support plate 3. A positioning block 5 is bolted to the top of the telescopic support plate 4. The position of the telescopic support plate 4 can be adjusted according to the size of the workpiece to make the center of gravity of the workpiece close to the electromagnet 8, thereby improving stability. A connecting frame 9 is welded to the side of the rotating base 2. A hydraulic cylinder 10 is set on the top of the connecting frame 9. A riveting joint 11 is fixedly connected to the output end of the hydraulic cylinder 10. Multiple feeding stations on the riveting turntable 1 can effectively improve the feeding speed. The rotating riveting turntable 1 is used to send the fixed workpiece to the riveting station, thereby improving work efficiency.

[0025] The positioning block 5 is a side-mounted "U" shaped structure. The top of the positioning block 5 is provided with a countersunk threaded hole 21, and a bolt is provided in the countersunk threaded hole 21. The side of the positioning block 5 is rotatably connected to a positioning rotating plate 6. The top of the positioning rotating plate 6 is vertically welded with a positioning column 7. The position of the positioning column 7 can be adjusted according to the contour of the part to be processed, so as to quickly position the part to be processed and improve the feeding speed.

[0026] Two telescopic rods 13 are fixedly connected to the top of the telescopic support plate 4. The telescopic rods 13 are slidably connected to the rotating support plate 3. A telescopic locking handwheel 20 is provided on the side of the rotating support plate 3 to facilitate adjustment of the position of the telescopic support plate 4 and make it easy to use.

[0027] Among them, a positioning conical hole 18 is provided between two adjacent rotating clearance grooves 16. The tip of the conical hole is a cylindrical hole. Six positioning electric push rods 23 are evenly distributed on the top of the rotating base 2. The output end of the positioning electric push rod 23 is slidably connected to the conical hole to accurately position the riveting turntable 1 and prevent the rivet from being misaligned with the riveting joint 11, which would affect the processing quality.

[0028] Among them, the top of the riveting turntable 1 is located at the side position of the rivet placement hole 14 and a material removal electric push rod 15 is provided. The output end of the material removal electric push rod 15 is normally located below the top of the riveting turntable 1. After the material removal electric push rod 15 lifts the part, the part slides off the riveting turntable 1 under the action of the center of gravity shift, realizing automatic material removal.

[0029] The riveting turntable 1 has a material collection trough 12 placed on its side. The edge of the material collection trough 12 fits the outer contour of the rotating base 2, increasing the contact area between the material collection trough 12 and the rotating base 2, and preventing the parts from falling out of the material collection trough 12 after being unloaded.

[0030] The working principle of this utility model is as follows: First, adjust the telescopic support plate 4 according to the size of the part to be processed so that the tail end of the part can be placed on the top of the positioning block 5. At the same time, adjust the angle of the positioning rotating plate 6 so that the positioning column 7 can fit against the edge of the part. For irregularly shaped parts, adjust the angle of the rotating support plate 3 so that the center of gravity of the part is near the electromagnet 8. When performing the riveting operation, the operator places the rivet in the rivet placement hole 14. The part to be processed is positioned in one place by the rivet, and the other end of the part to be processed is fitted against the positioning column 7 for another position. The operator can quickly position the part through two positions. Activate the electromagnet 8 located on the rotating support plate 3, and use magnetic attraction to fix the part to be processed on the riveting turntable 1 and the electromagnet 8. The part is positioned firmly and accurately, improving the feeding efficiency. When the work station changes... During operation, the positioning electric push rod 23 first retracts and contacts the rotating riveting turntable 1. The stepper motor 22 rotates, driving the riveting turntable 1 to rotate for position change. The positioning electric push rod 23, located on the rotating base 2, works again. When there is an error in the rotation angle of the riveting turntable 1, the output end of the positioning electric push rod 23 repositions the riveting turntable 1 during the sliding connection with the positioning conical hole 18. The positioning is accurate, improving the processing quality. When the part moves to below the riveting joint 11, the hydraulic cylinder 10 works, and the riveting joint 11 performs riveting operations on the rivet and the part. When the riveted part leaves the riveting station, the electromagnet 8 at the riveting station stops working, releasing the fixation of the processed part. At the same time, the ejector electric push rod 15 works to lift the part, changing the center of gravity of the part. The processed part slides into the collection trough 12 under the action of gravity, making it convenient to use.
