[0002] A riveting machine is a mechanical device that uses rivets to join items together. It is characterized by its compact structure, stable performance, and ease of operation. Riveting machines primarily rely on rotation and pressure to complete assembly. Common types include automatic riveting machines and spin riveting machines. The cold rolling riveting method using a spin riveting machine involves applying localized pressure to the rivet with a rivet rod and continuously oscillating it around a center until the rivet is formed. Based on the cold rolling trajectory of this riveting method, it can be divided into oscillating riveting and radial riveting.
[0003] The rivet rod installation structure of the servo pressure riveting machine currently used with tensioners may be quite complex, relying on multiple nested mechanical components for fixation. Under long-term high-load operation, the rivet rod is prone to damage when subjected to impact. As wear intensifies, the dimensional accuracy of the rivet rod gradually decreases, and its fit with the riveting part of the tensioner deteriorates, severely affecting the overall performance and reliability of the tensioner, and impacting the product's appearance and performance. Therefore, a servo pressure riveting machine with tensioner assembly is proposed to solve the above problems. Utility Model Content

[0031] 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.
[0032] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a servo pressure riveting machine equipped with a tensioner, comprising a work frame 1. A safety light curtain 2 is fixedly connected to the inner side of the work frame 1. During operation, the safety light curtain 2 acts as a protective barrier, preventing foreign objects from accidentally entering the work area and damaging the equipment, thereby effectively avoiding potential hand injuries and greatly protecting the life and health of operators. A drive assembly is installed inside the safety light curtain 2. An electrical control box 5 is fixedly connected to the bottom of the work frame 1. The electrical control box 5 serves as the control core of the servo pressure riveting machine, responsible for receiving parameters set from input devices such as the control console 7 or touch screen 6, and converting these parameters into corresponding electrical signals, ensuring the smooth operation of the entire assembly process and improving production efficiency and product quality. A sliding assembly is mounted externally on the electrical control box 5; the drive assembly includes an electric push rod 9, which is externally fixedly connected to the outside of the work frame 1. A main shaft 17 is fixedly connected to the end of the electric push rod 9, and an annular fixing block 18 is externally fixedly connected to the main shaft 17. A fixing bolt 19 is rotatably connected to the outside of the annular fixing block 18. A rivet rod 11 is internally fixedly connected to the main shaft 17, and a drive shaft 10 is provided externally on the work frame 1. The rivet rod 11 is rotatably connected to the inside of the work frame 1, and the electric push rod 9 is slidably connected to the inside of the safety light curtain 2.
[0033] Reference Figure 1 - Figure 3 The sliding assembly includes a slide rod 13, which is fixedly connected to the outside of the electrical control box 5. A sliding worktable 12 is slidably connected to the outside of the slide rod 13. A cylinder 14 is fixedly connected to the outside of the sliding worktable 12. A fixing block 15 is fixedly connected to the top of the sliding worktable 12. The tensioner components to be assembled are placed on the fixing block 15 on the sliding worktable 12. The cylinder 14 can push the sliding worktable 12 to slide on the slide rod 13, facilitating the movement of the tensioner to be assembled. Pressure is then applied using a rivet rod 11 for precise positioning and assembly. A control console 7 is fixedly connected to the outside of the electrical control box 5. A door 3 is rotatably connected to the outside of the electrical control box 5. A handle 8 is fixedly connected to the outside of the door 3, allowing the door 3 to be opened and closed via the handle 8 for easy maintenance and repair of the electrical control box 5. Casters 4 are fixedly connected to the bottom of the electrical control box 5, facilitating the overall movement and layout adjustment of the equipment. The work frame 1 is externally fixedly connected to a touch screen 6, and internally slidably connected to a button switch 16. The parameters of the riveting machine can be adjusted by using the button switch 16 and the touch screen 6.
[0034] Working Principle: The tensioner components to be assembled are placed on the fixed block 15 on the sliding worktable 12. The position of the components in the direction of the slide rod 13 can be adjusted by the cylinder 14 for precise positioning. When the equipment is started, the electrical control box 5 sends instructions to the drive assembly according to the parameters preset on the control console 7 or touch screen 6. After receiving the signal, the electric push rod 9 starts to work. Its external connection to the work frame 1 ensures stable support. The end of the electric push rod 9 drives the main shaft 17 to move linearly inside the safety light curtain 2. The rivet rod 11 inside the main shaft 17 moves synchronously. The main shaft 17 and the drive shaft 10 are fixed with fixing bolts 19 to stabilize the structure. In addition, when the rivet rod 11 is damaged due to long-term use, it can be replaced by rotating the fixing bolts 19, improving replacement efficiency.
[0035] When the rivet 11 contacts the rivet part of the tensioner, the main shaft 17 applies pressure to the rivet 11 under the continued push of the electric push rod 9. The combined action of rotation and pressure causes plastic deformation of the rivet, thereby tightly connecting the various components of the tensioner together. Throughout the process, the safety light curtain 2 ensures safety during use. The casters 4 at the bottom of the electrical control box 5 facilitate the overall movement and layout adjustment of the equipment. The box door 3 can be opened and closed via the handle 8, facilitating maintenance and repair operations inside the electrical control box 5.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
