[0014] 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 description of the textual part of the specification 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.

[0015] See appendix Figure 1-2This application provides a dual-station riveting machine, which includes a riveting head 2, a horizontal rail 3, a vertical rail 4, and two riveting stations 5 mounted on a worktable 1. The two riveting stations 5 are arranged side by side along the extension direction of the horizontal rail 3. The vertical rail 4 is slidably connected to the horizontal rail 3. The horizontal rail 3 is provided with a first driving component for driving the vertical rail 4 to slide. The riveting head 2 is slidably connected to the vertical rail 4. The vertical rail 4 is provided with a second driving component 6 for driving the riveting head 2 to slide. Each riveting station 5 includes a linear guide rail 51 and a feeding table 52. The device includes a pressing unit and a tooling mold 53. The feeding table 52 is slidably connected to and driven by the linear guide rail 51. The tooling mold 53 and the pressing unit are located on the feeding table 52. The pressing unit is used to hold the workpiece on the tooling mold 53. From a top-down perspective, the linear guide rail 51 and the horizontal rail 3 are perpendicular to each other. This solution achieves a cyclical alternation working mode of riveting operation at one riveting station 5 and simultaneous loading and unloading at the other riveting station 5 through the coordinated design of components such as the horizontal rail 3, the vertical rail 4, and the two riveting stations 5. This layout eliminates the waiting time during loading and unloading of traditional single-station equipment, allowing the riveting operation to be carried out almost continuously, thus multiplying production efficiency.

[0016] The pressing part includes a first cylinder 7 and a pressing head 8. The bottom of the first cylinder 7 is fixed on the feeding table 52. The pressing head 8 is connected to the cylinder shaft of the first cylinder 7. The surface of the pressing head 8 is covered with a soft rubber layer. The first cylinder 7 drives the pressing head 8 covered with the soft rubber layer, which can effectively prevent damage to the surface of the workpiece. It is especially suitable for precision parts with high surface finish requirements, improving processing quality and product yield.

[0017] A control module 9 is provided on the other end of the linear guide rail 51 away from the horizontal rail 3. The control module 9 is electrically connected to the linear guide rail 51, the pressing part and the riveting head 2. The operator can operate the linear guide rail 51, the pressing part and the riveting head 2 from a safe position through the control module, thereby improving the operational safety of the equipment.

[0018] The first drive assembly includes a lead screw 10 and a motor 11. The lead screw 10 is rotatably mounted on the horizontal rail 3 and is parallel to the horizontal rail 3. The motor 11 is mounted on the horizontal rail 3 and drives the lead screw 10 to rotate. The vertical rail 4 has a threaded sleeve that is screwed to the lead screw 10. The motor 11 drives the lead screw 10 to rotate, and the vertical rail 4 can slide along the horizontal rail 3. The reciprocating motion of the vertical rail 4 can be easily controlled by switching the rotation direction of the motor 11.

[0019] The second drive component 6 is a second cylinder, which is installed upside down on the top of the vertical rail 4. The cylinder shaft of the second cylinder is connected to the riveting head 2. The cylinder has the advantage of rapid response, which can meet the requirements of rapid lifting and lowering, and is conducive to further improving production efficiency.

[0020] The workbench 1 is surrounded by protective nets 12 on its left, rear, and right sides. The bottom of the protective nets 12 is fixed to the workbench 1 with screws. The protective nets 12 effectively prevent debris, oil, and other foreign objects generated during processing from flying and injuring people, thus improving the safety of the equipment. At the same time, the screw fixing makes it easy to install and remove the protective nets 12, facilitating the maintenance and cleaning of the equipment.

[0021] The workbench 1 is equipped with human infrared sensors 13 on both sides of the riveting station 5. The human infrared sensors 13 are electrically connected to the riveting head 2. When the human infrared sensors 13 detect that a person is too close to the danger area, they can cut off the power to the riveting head 2 or stop its operation in time, which greatly avoids possible personal injury accidents.

[0022] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments.
