[0024] Specific examples are given below.

[0025] See also Figure 1-Figure 5The utility model provides a muffler riveting device, comprising a workbench 1; a riveting assembly is arranged on the workbench 1, and the riveting assembly includes a riveting press 14 for riveting the muffler pipe; a disc 6 is fixedly connected to the top of the workbench 1; a limiting assembly is arranged on the top of the disc 6, and the limiting assembly includes a roller 21 for limiting the muffler; a thread groove 7 is opened on the disc 6; a plurality of thread grooves 7 are arranged and are equidistantly arranged on the disc 6; a screw rod 8 is rotatably connected in the thread groove 7; a thread block 9 is threadedly connected to the screw rod 8; a connecting column 10 is fixedly connected to the top of the thread block 9; a connecting block 11 is fixedly connected to the top of the connecting column 10; a fixing clamp 12 is fixedly connected to the connecting block 11; when working, the central hollow of the muffler pipe is inserted into the limiting assembly, and after being inserted into the limiting assembly, the muffler pipe is adjusted by the roller 21 in the limiting assembly so that the muffler pipe is kept at the center position of the disc 6, and then the external motor is started to drive the three screw rods 8 is rotated, and the screw rod 8 rotates to drive the threaded block 9 on the screw rod 8 to move. The threaded block 9 moves with the connecting column 10, the connecting block 11 and the fixing clip 12 at the top of the threaded block 9 to approach the muffler, and moves to the three fixing clips 12 to clamp the muffler. At this time, the screw rod 8 stops rotating. When the muffler is firmly fixed, the riveting machine 14 is started to rivet the muffler. In this way, it is avoided that the muffler deviates from the center position or the muffler is shaken down due to shaking when the machine is started, and manual support is required, which reduces certain safety hazards. Although the screw rod 8 rotates at the same time and brings the fixing clip 12 close to the muffler and fixes the muffler tightly, different threads may still occur, so that the fixing clip 12 is pressed against the muffler pipe front and back. At this time, the limit assembly is required to control it. When the fixing clip 12 is pressed against the muffler at different times, the muffler will be offset. The limit assembly is fine-tuned internally to keep the muffler in the center position, so that the riveting machine 14 can accurately rivet the parts of the muffler that need to be riveted.

[0026] Further, such as Figure 2 and Figure 3As shown, the top of the disc 6 is fixedly connected to a fixed leg 17; the top of the fixed leg 17 is fixedly connected to a support platform 15; the center position of the top of the support platform 15 is fixedly connected to a sliding column 16; the sliding column 16 is slidably connected to a sliding ring 18; the sliding ring 18 is fixedly connected to a rotating column 19; the rotating column 19 is rotatably connected to a moving rod 20; the end of the moving rod 20 away from the rotating column 19 is rotatably connected to a roller 21. When working, the central hole of the muffler is inserted into the sliding column 16, and the moving rod 20 is first moved along the rotating column when the muffler is inserted into the sliding column 16. 19 is rotated until the moving rod 20 is vertically upward and parallel to the sliding column 16. After the moving rod 20 is adjusted, the silencer is put on the sliding column 16. At this time, the moving rod 20 will make a free fall without the action of external force. When the moving rod 20 falls to the vertical device, the sliding ring 18 also slides downward. When the sliding ring 18 slides downward, the roller 21 on the moving rod 20 contacts the object support platform 15 and makes the moving rod 20 open outward. When the roller 21 slides to the top of the moving rod 20 and contacts the inner wall of the silencer, the sliding ring 18 stops sliding down and the silencer is limited to the center position of the object support platform 15.

[0027] Further, such as Figure 1 and Figure 2 As shown, the side wall of the workbench 1 is fixedly connected with a support block 3; two support blocks 3 are provided and are symmetrically arranged on both sides of the workbench 1; the top of the support block 3 is fixedly connected with a support column 4; the top of the support column 4 is fixedly connected with a cross bar 5. When working, the support block 3 and the support column 4 on the workbench 1 play the role of fixing the support cross bar 5, and the cross bar 5 serves to connect and fix the working parts arranged on the cross bar 5.

[0028] Further, such as Figure 2 and Figure 4 As shown, a telescopic rod 13 is fixedly connected to the bottom center of the cross bar 5; the output end of the telescopic rod 13 is fixedly connected to a riveter 14. During operation, after the muffler is fixed, the telescopic rod 13 is extended and retracted to send the riveter 14 at the output end of the telescopic rod 13 to the muffler for the riveting process of the muffler.

[0029] Further, such as Figure 4 and Figure 5 As shown, there are multiple fixed legs 17, which are equidistantly arranged on the disc 6; there are three rotating columns 19, which are equidistantly arranged on the sliding column 16. When working, multiple fixed legs 17 are provided to maintain the stability of the object support platform 15 and the devices on the top of the object support platform 15, and three rotating columns 19 are provided to allow the three rotating columns 19 to carry the moving rod 20 and the roller 21 to better limit the silencer and find the center position.

[0030] Further, such as Figure 1As shown, a support leg 2 is fixedly connected to the bottom of the workbench 1; four support legs 2 are provided and are respectively arranged at the bottom of the workbench 1. When working, the support legs 2 at the bottom of the workbench 1 support the workbench 1. Multiple support legs 2 are provided to keep the workbench 1 stable during work.

[0031] Working principle: insert the central hole of the silencer into the limit assembly, and after inserting into the limit assembly, the roller 21 in the limit assembly adjusts the silencer to keep the silencer at the center of the disc 6, and then start the external motor to drive the three screw rods 8 to rotate, the screw rod 8 rotates to drive the threaded block 9 on the screw rod 8 to move, the threaded block 9 moves with the connecting column 10, the connecting block 11 and the fixing clamp 12 on the top of the threaded block 9 to approach the silencer, move to the three fixing clamps 12 to clamp the silencer, then the screw rod 8 stops rotating, when the silencer is firmly fixed, start the riveting press 14 to rivet the silencer, so that This avoids the situation where the silencer deviates from the center position or is shaken down due to shaking when the machine is started, and the need for manual support is reduced, thereby reducing certain safety hazards. Although the screw rod 8 rotates at the same time to bring the fixing clip 12 closer to the silencer and fix the silencer tightly, different threads may still occur, causing the fixing clip 12 to press against the silencer pipe front and back. At this time, the limit assembly is required to control it. When the fixing clip 12 presses against the silencer at different times, the silencer will be offset, and the limit assembly will be fine-tuned internally to keep the silencer in the center position at all times, so that the riveter 14 can accurately rivet the parts of the silencer pipe that need to be riveted.
