Detailed Implementation
[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0024] Reference Figure 1-4 This utility model discloses an automatic positioning high-efficiency rivet riveting machine, comprising a frame 1 and a second electric telescopic rod 6. A through hole 2 is provided at the bottom of the frame 1, and a first electric telescopic rod 3 is disposed inside the frame 1. The output end of the first electric telescopic rod 3 passes through the through hole 2 and extends to the surface of the frame 1. This allows for manual insertion of the surface of the item to be riveted through the output end of the first electric telescopic rod 3, followed by placement on the platform of the frame 1. This design improves riveting efficiency and accuracy, and achieves the positioning effect of the item to be riveted. The diameter of the through hole 2 is much smaller than the diameter of the rivet, ensuring that the rivet will not fall into the through hole 2. A hydraulic cylinder 4 is fixedly connected to the top of the frame 1. One end of the device is equipped with a hydraulic rod 5 for riveting. After the positioning and fixing of the items to be riveted are completed, the hydraulic cylinder 4 is activated to press the lower end of the hydraulic rod 5 downward. The lower end of the hydraulic rod 5 is fixedly connected to a small bolt 17, and the bottom end of the small bolt 17 is bolted to the pressure head 18. If necessary, the model of the pressure head 18 can be changed or replaced with a new one, which greatly improves the applicability of the device. That is, multiple models of pressure heads 18 can be used to rivet the items to be riveted. The upper part of the frame 1 is fixedly connected to a second electric telescopic rod 6. The output end of the second electric telescopic rod 6 is fixedly connected to a pressure plate 7. The pressure plate 7 can fix the items to be riveted that have been positioned, which facilitates the determination of the accuracy of the subsequent riveting process.
[0025] The above structure, by setting a first electric telescopic rod 3, allows the output end of the first electric telescopic rod 3 to extend out and position the small holes on the surface of the item to be riveted. This allows the operator to easily ensure that the hole to be riveted is in a straight line with the pressure head 18, thus ensuring the accuracy of the riveting work. By setting a second electric telescopic rod 6, the output end of the second electric telescopic rod 6 presses the pressure plate 7 against the item to be riveted. After the rivet placement and positioning of the item to be riveted are completed, the pressure plate 7 firmly presses the item to be riveted, ensuring that the item to be riveted will not move during riveting, thereby preventing a decrease in riveting quality.
[0026] A third electric telescopic rod 8 is fixedly connected to the front of the frame 1. A fixed block 9 is fixedly connected to the output end of the third electric telescopic rod 8. By setting the third electric telescopic rod 8, the fixed block 9 can be pushed outward, thereby adjusting the position of the support block 11 and the tray 12, which is highly applicable. A fourth electric telescopic rod 10 is set on the top of the fixed block 9. The support block 11 is fixedly connected to the output end of the fourth electric telescopic rod 10. The surface of the support block 11 is provided with two slots 16, and a bidirectional threaded rod 14 is provided inside. A small turntable 13 is provided at one end of the bidirectional threaded rod 14. Threaded blocks 15 are threaded to both ends of the bidirectional threaded rod 14. A tray 12 is fixedly connected to one end of the threaded block 15. With the arrangement of the bidirectional threaded rod 14, threaded blocks 15, tray 12, small turntable 13 and slots 16, the device can drive the bidirectional threaded rod 14 to move the threaded blocks 15 and the tray 12 in the opposite direction by rotating the small turntable 13.
[0027] The above structure, through the setting of the third electric telescopic rod 8, can push the fixed block 9 outward, thereby adjusting the position of the support block 11 and the tray 12, which is highly applicable. Through the setting of the bidirectional threaded rod 14, the threaded block 15, the tray 12, the small turntable 13 and the slot 16, the device can rotate the small turntable 13 to actuate the bidirectional threaded rod 14 to drive the threaded block 15 and the tray 12 to move in the opposite direction. These structures can make the tray 12 and the support block 11 adapt to various sizes of items to be riveted, which is highly applicable.
[0028] Working principle: First, the output end of the first electric telescopic rod 3 extends out of the through hole 2. Then, the hole of the item to be riveted is manually passed through the output end of the first electric telescopic rod 3 and placed on the plane of the frame 1. The fixing block 9 is moved longitudinally by the third electric telescopic rod 8, and the vertical height of the support block 11 is adjusted by the fourth electric telescopic rod 10. The bidirectional threaded rod 14 is manually rotated through the small turntable 13, which drives the threaded blocks 15 at both ends to move synchronously in opposite directions, so that the tray 12 can be adjusted according to the size of the item to be riveted, making it highly adaptable. Then, the tray 12 is controlled by the fourth electric telescopic rod 10. The first electric telescopic rod 3 retracts its output end, and the rivet is manually placed into the center of the through hole 2. Then, the fourth electric telescopic rod 10 lowers the item to be riveted, ensuring the hole in the item passes perfectly through the rivet. The second electric telescopic rod 6 then drives the pressure plate 7 to press down, clamping the workpiece in conjunction with the bottom support to ensure stability during riveting. After the hydraulic cylinder 4 is activated, the hydraulic rod 5 drives the small bolt 17 and the replaceable pressure head 18 to press down at high speed, applying precise punching force to the rivet and completing the plastic deformation riveting. By changing the threaded pressure head 18 to different specifications, it can adapt to various rivet types, improving the equipment's versatility. After riveting, the second electric telescopic rod 6, the third electric telescopic rod 8, and the hydraulic cylinder 4 reset sequentially. The output end of the first electric telescopic rod 3 still extends above the surface of the frame 1 to facilitate the next round of positioning work. The equipment then returns to its initial state, ready for the next cycle.
[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
