[0017] 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.

[0018] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "horizontal," "vertical," "top," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] Please see Figures 1 to 4This utility model provides an embodiment of a rivet pressing device, including a pressing component 10 and a rotating component 20. The pressing component 10 includes a fan-shaped fixing frame 11 and two pressing modules 12 disposed on the fan-shaped fixing frame 11. The pressing module 12 includes a lifting mechanism and a pressing block disposed on the movable end of the lifting mechanism. The pressing block can be used to press the rivet up and down. The rotating component 20 includes at least a turntable 21 and a plurality of positioning fixtures 22 disposed on the turntable 21. The distance between any two adjacent custom fixtures 22 is adapted to the positioning distance of the two pressing modules 12. The turntable 21 rotates the plurality of positioning fixtures 22 to transport materials, improving the efficiency of loading and unloading. Then, the two pressing modules 12 respectively press the two positioning fixtures 22, improving the riveting efficiency. The fan-shaped fixing frame 11 can maintain the stable support of the two pressing modules and ensure the riveting effect.

[0020] It also includes two top pressing frames 13, which are located directly below the two pressing modules 12. Each top pressing frame 13 is movably connected to a roller 14 at its top. A soft rubber layer is provided on the circumferential end face of the roller 14. The roller 14 abuts against the bottom surface of the turntable. When the product is riveted, the roller 14 lifts the turntable 21, improves the overall support of the riveting pressing device, and ensures the riveting effect.

[0021] The positioning fixture 22 has several longitudinal through holes 23, and each through hole 23 is provided with a pin 24. The pin 24 is inserted into the corresponding through hole 23 from bottom to top, and the pin 24 can slide up and down in the through hole 23.

[0022] The positioning fixture 22 is provided with a movable seat 25 below it. The movable seat 25 is also provided with a number of guide posts 26. The number of guide posts 26 corresponds to a number of through holes 23 one by one, and the guide posts 26 are inserted into the corresponding through holes 23 from bottom to top. The ejector pin 24 is provided on the guide post 26.

[0023] The movable seat 25 and the ejector pin 24 can slide in the up and down direction, while the guide post 26 slides relative to each other in the through hole 23. While the ejector pin 24 moves up and down, it can make the rivet fit more snugly into the ejector pin 24, thereby improving the positioning effect of the rivet and the positioning fixture 22.

[0024] Furthermore, the product has holes for inserting the ejector pin 24, and the rivet has round holes for inserting the ejector pin 24. The ejector pin 24 is inserted into the holes of the product and the round holes of the rivet from bottom to top, so as to achieve relative positioning of the product, the rivet and the positioning fixture.

[0025] In this embodiment, a limiting boss 27 is provided on the positioning fixture 21, and a through hole 23 is provided on the limiting boss 27. The limiting boss 27 can be fitted with the product and fitted with the ejector pin 24 for limiting, which further improves the positioning effect between the product and the positioning fixture 22.

[0026] The rotating module 20 includes a rotating motor 28 and a reducer 29 that is linked to the rotating motor 28, and the movable end of the reducer 29 is linked to the turntable 21.

[0027] Furthermore, the rotary motor 28 is a servo motor, which can be controlled by a PLC program to rotate the servo motor a certain number of times, so that the turntable 21 can rotate at the set angle, and the positioning fixture 22 can be moved to the set position for the next processing step.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
