[0026] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0027] In the description of the present utility model, "multiple" means two or more than two, unless otherwise clearly specified and specifically defined. In the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0028] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1 As shown, an automatic riveting machine includes a frame 1. Slide rails 2 are provided on both sides of the frame 1. A connecting seat 3 is slidably connected to the slide rails 2. An output rod 4 is connected to the middle of the connecting seat 3. The output rod 4 is connected to a hydraulic cylinder 5, and a pressure plate 6 is provided at the bottom of the connecting seat 3 for riveting. Rivets can be automatically input at the riveting position through a spiral conveyor disk, etc., or rivets can be directly inserted into the workpiece for a preliminary riveting process to perform a subsequent riveting process. The above is the setting of a general riveting machine, which is a prior art and will not be repeated in this application.

[0030] The core technical solution of this application is as follows:

[0031] like Figure 2 , Figure 3As shown, in order to solve the purpose of feeding the workpiece outside the riveting position and automatically conveying the workpiece, the present application is provided with a slide groove 7 on one side of the frame 1. A slider 8 is slidably connected in the slide groove 7. One end of the slider 8 is fixedly connected to the connecting seat 3. The other end of the slider 8 passes through the slide groove 7 and is fixedly connected to the driving frame 9.

[0032] like Figure 4 As shown, staggered longitudinal grooves 10 are provided on both sides of the driving frame 9. An inclined groove 11 is connected between the longitudinal grooves 10. The longitudinal grooves 10 and the inclined grooves 11 together form a broken line groove. Correspondingly, a positioning rod 12 is provided in the inclined groove 11. A rotating wheel 13 is eccentrically connected to one end of the positioning rod 12. The rotating wheel 13 is connected to a connecting block 14 by a bearing. The connecting block 14 is fixedly connected to the frame 1.

[0033] In the above, the case where the connecting seat 3 moves upward under the action of the hydraulic cylinder 5 is taken as an example. When the hydraulic cylinder 5 drives the connecting seat 3 to move upward, it drives the slider 8 to move upward in the slide groove 7. The upward movement of the slider 8 drives the driving frame 9 to move upward, so that the inclined groove 11 on the driving frame 9 gradually moves upward. In this process, the positioning rod 12 rotates under the action of the upward movement of the inclined groove 11. When the connecting seat 3 moves upward to the extreme position, the positioning rod 12 drives the rotating wheel 13 to rotate one circle. At this time, the positioning rod 12 is at the end of the inclined groove 11. Under the above setting, the linear motion of the driving frame 9 is converted into the unidirectional rotational motion of the rotating wheel 13. The driving frame 9 reciprocates up and down once, and the rotating wheel 13 rotates one circle, that is, when it moves upward, the rotating wheel 13 rotates half a circle, and when it moves downward, the rotating wheel 13 rotates half a circle.

[0034] As mentioned above, the width of the rotating wheel 13 is smaller than the transverse width of the inclined slot 11 .

[0035] like Figure 2 , Figure 5 As shown, further, a driving wheel 15 is provided on one side of the rotating wheel 13. The driving wheel 15 is connected to the rotating wheel 13 by a belt 16. A rotating shaft 17 is passed through the middle of the driving wheel 15, and a positioning frame 18 is connected to one end of the rotating shaft 17 by a bearing. A small gear 19 is connected to the other end of the rotating shaft 17. A large gear 20 is meshed on one side of the small gear 19. Among them, a transmission shaft (not shown in the figure) is connected to the middle of the large gear 20. The transmission shaft is connected to a conveying shaft 21. The conveying shaft 21 is connected to the positioning frame 18 by a bearing.

[0036] As mentioned above, two conveying shafts 21 are provided, which are respectively placed on both sides of the frame 1. A conveying belt 22 is provided on the conveying shaft 21. The middle of the conveying belt 22 is hollowed out, and a plurality of mounting plates 23 arranged in sequence are provided. The mounting plate 23 is provided with a mounting groove 24 having the same shape as the workpiece.

[0037] When the hydraulic cylinder 5 drives the connecting seat 3 to move up to the top, the rotating wheel 13 rotates one circle, causing the small gear 19 to rotate and driving the large gear 20 to rotate. The rotation of the large gear 20 drives the conveying shaft 21 to rotate an angle. The number of teeth of the large gear 20 is greater than that of the small gear 19. The rotation of the conveying shaft 21 drives the conveyor belt 22 to move forward. The unit distance of movement is as follows: Figure 2 Before the hydraulic cylinder 5 drives the connection seat 3 to move downward for riveting, the conveyor belt 22 continues to move a hollow distance, so that the mounting plate 23 enters the riveting position, at which time the hydraulic cylinder 5 continues to drive the connection seat 3 downward, at which time the slider 8 moves along the longitudinal groove 10, and the rotating wheel 13 does not rotate, so that the connection seat 3 drives the pressing plate 6 to perform the riveting process.

[0038] Under the above arrangement, the staff can place the stacked workpieces with rivets on the mounting plate 23 on one side of the conveyor belt 22, away from the riveting area, thereby improving the safety factor, reducing safety hazards, and automatically inputting the workpieces into the riveting area.

[0039] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
