[0032] Reference Figure 1-4 , an embodiment provided by the utility model:

[0033] A multi-station riveting machine comprises a workbench 2, a mounting frame 1 is fixedly arranged on the upper end of the workbench 2, a hydraulic cylinder 5 is fixedly arranged on the upper end of the mounting frame 1, two fixing rings 8 are fixedly arranged on the outer side of the output end of the hydraulic cylinder 5, a protective cover 10 is slidably arranged on the outer side of the output end of the hydraulic cylinder 5, a motor 15 is fixedly arranged inside the workbench 2, a turntable 9 is fixedly arranged on the output end of the motor 15, a riveting head 14 is fixedly arranged on the output end of the hydraulic cylinder 5, the turntable 9 is rotatably arranged on the outer side of the workbench 2, a plurality of placement slots 11 are opened on the upper end of the turntable 9, a mounting slot 6 is opened on the front end of the mounting frame 1, and the rear end of the protective cover 10 is slidably arranged inside the mounting slot 6;

[0034] When the workpiece is subjected to riveting processing, the workpiece is precisely placed in the placement groove 11 on the turntable 9, and then the motor 15 inside the workbench 2 activates the turntable 9 and drives it to rotate, so that each workpiece enters the set riveting point in turn. At this time, the hydraulic cylinder 5, as a power source, will start to extend at its output end, leading the riveting head 14 to move downward. At the same time, the protective cover 10 at the output end of the hydraulic cylinder 5 will also slide with it. When the protective cover 10 slides, its rear end will slide in the mounting groove 6 opened on the outside of the mounting frame 1. The mounting groove 6 makes the protective cover 10 run stably. When the protective cover 10 covers the top of the workbench 2, it will provide additional safety protection for the operating environment. In this environment, the riveting head 14 performs efficient, safe and precise riveting operations on the workpiece that arrives at the working position. The protective cover 10 can effectively isolate the operating area, protect the operator from mechanical damage, improve the safety performance of the equipment, thereby improving work efficiency, while also ensuring the safety of the operation process, and realizing smooth and reliable production operations.

[0035] Two connecting blocks 20 are fixedly provided at the rear end of the protective cover 10, and slide grooves 7 are provided on both sides of the mounting frame 1. The exteriors of the two connecting blocks 20 are slidably arranged inside the slide grooves 7. A second cylinder 21 is fixedly provided inside the mounting frame 1, and the opposite sides of the two connecting blocks 20 are fixedly provided on both sides of the output end of the second cylinder 21. A first cylinder 19 is fixedly provided inside the workbench 2 at the rear end, and a limiting block 18 is fixedly provided at the output end of the first cylinder 19. A plurality of limiting grooves 12 are provided on the exterior of the turntable 9, and the limiting block 18 is slidably arranged outside the workbench 2 at the rear end, and the limiting block 18 is slidably arranged inside one of the plurality of limiting grooves 12, and the output end of the second cylinder 21 is slidably arranged inside the mounting frame 1;

[0036] As the protective cover 10 descends, the connecting block 20 at its rear end will slide in the slide groove 7 provided in the mounting frame 1. The connecting block 20 is connected to the output end of the second cylinder 21. When the connecting block 20 moves, the second cylinder 21 will contract, and the gas inside it will be guided into the first cylinder 19 through the internal air pipe, thereby prompting the first cylinder 19 to extend. The principle of gas pressure transmission is utilized to achieve efficient conversion and utilization of energy. The extension movement of the first cylinder 19 will drive the limit block 18 to slide inside the workbench 2, so that the limit block 18 is accurately embedded in the limit groove 12 outside the turntable 9, thereby achieving precise positioning of the turntable 9, so that the turntable 9 remains stable during the riveting process, and riveting errors caused by the movement of the turntable 9 are prevented.

[0037] A vacuum cleaner 16 is fixedly arranged inside the workbench 2, and a vacuum head 17 is fixedly arranged at the front end of the mounting frame 1. When dust and impurities are generated during the riveting process, the vacuum cleaner 16 inside the workbench 2 is activated so that the vacuum head 17 on the mounting frame 1 can suck out the dust and debris generated during the working process, which not only keeps the working environment clean and avoids the influence of dust and debris on the quality of the workpiece, but also improves the working environment of the operator. Multiple ventilation slots 13 are provided on both sides of the workbench 2. The design of the ventilation slots 13 helps to dissipate heat from the equipment and prolong the service life of the equipment. Four supporting legs 4 are threadedly connected at the lower end of the workbench 2. The supporting legs 4 can improve the stability of the equipment, and by rotating the supporting legs 4 threadedly connected under the workbench 2, the workbench 2 can be moved to the required height, which is easy to operate. A cabinet door 3 is hingedly arranged at the front end of the workbench 2. The hinged cabinet door 3 is not only convenient to operate, but also can quickly maintain and repair the equipment, and is convenient for storing tools and accessories, thereby improving on-site management efficiency.

[0038] Working principle: When performing riveting processing on a workpiece, first place the tool to be processed into the placement slot 11 on the turntable 9, and then drive the turntable 9 to rotate through the motor 15, so that multiple workpieces on the turntable 9 can enter the riveting position in turn. At this time, the hydraulic cylinder 5 provides the driving force required for riveting, and its output end extends to drive the riveting head 14 to move downward. At the same time, the protective cover 10 on the output end of the hydraulic cylinder 5 will move synchronously. When the protective cover 10 moves downward, its rear end will slide in the mounting slot 6 opened on the outside of the mounting frame 1, and its internal connecting block 20 will be on both sides of the mounting frame 1. The second cylinder 21 is driven to retract and the gas in the second cylinder 21 flows into the first cylinder 19 through the air pipe inside the equipment, so that the first cylinder 19 extends and drives the limit block 18 to slide inside the workbench 2, so that the limit block 18 slides into the limit groove 12 outside the turntable 9, so as to position the turntable 9. When the protective cover 10 reaches the upper end of the workbench 2, it will provide protection for the operation. At this time, the rivet head 14 will perform efficient, safe and accurate rivet operations on the workpiece placed in the slot 11.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
