[0003] Traditional muffler welding mainly relies on manual operation for fixing, which has poor fixing effect; some are fixed by clamps, but the clamps cannot be used to hold and fix mufflers of different sizes, making it difficult to meet the diverse production needs. Utility Model Content
[0004] The main objective of this invention is to provide a silencer welding device to solve the aforementioned technical problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a silencer welding device, including a base, a driving structure on the base, a bracket at the output end of the driving structure, a mounting plate at the top of the bracket, and a limiting structure on the mounting plate; a frame on one side of the top of the base, an electric push rod at the top of the frame, a welder at the output end of the electric push rod, and a welding head at the output end of the welder.
[0006] Based on the above scheme and as a preferred embodiment: the limiting structure includes a support plate disposed on the surface of the mounting plate and three sets of sliding supports arranged in annular array on the outer periphery of the support plate. The sliding supports have slots, the bottom of the slots has sliding grooves, and the sliding grooves contain sliders. The top of the sliders is rotatably connected to a rocker arm, and the other end of the rocker arm is provided with an arc-shaped limiting block. The top surface of the arc-shaped limiting block is provided with an annular plate, and a pin is rotatably mounted between the rocker arm and the annular plate. The bottom of the annular plate is provided with a fixing block, and the fixing block is provided with a drive rod.
[0007] Based on the above solution and as a preferred embodiment: a connecting block is provided between the bottom of the annular plate and the support plate, and the support plate is rotatably connected to the mounting plate.
[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the length of the chute is less than the length of the groove opening.
[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the limiting end of the arc-shaped limiting block is provided with a rubber anti-slip pad.
[0010] Based on the above scheme and as a preferred embodiment of the above scheme: an extension plate is provided on one side of the mounting plate, a limiting groove is provided on the extension plate, and a plurality of limiting holes are provided in the limiting groove; a telescopic rod is provided on one side of the drive rod, and the telescopic rod is detachably connected to the limiting holes.
[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the drive structure includes a motor, the output end of the motor is provided with a lead screw, the lead screw is provided with a moving block, and the top of the moving block is fixedly connected to the bracket.
[0012] The beneficial effects of this utility model are as follows: This device drives the annular plate to rotate via a drive rod.

The annular plate and the rocker arm are rotatably connected by a pin, and the three sets of rocker arms also move accordingly. The other end of the rocker arm can slide in the sliding support. The rotational movement achieved by the drive rod allows the three sets of arc-shaped limiting blocks at one end of the three sets of rocker arms to move closer to or separate from each other, thereby achieving the clamping of mufflers of different sizes. After clamping, the drive rod can be fixed by engaging the telescopic rod on one side of the drive rod with the limiting hole in the limiting groove on the extension plate. Then, the motor drives the lead screw to rotate, which in turn moves the moving block, thereby driving the bracket and the limiting structure to approach the welding head for welding operations.

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.
[0018] See attached diagram. Figures 1 to 4A silencer welding device in this embodiment includes a base 1, a drive structure on the base 1, a bracket 2 at the output end of the drive structure, a mounting plate 3 at the top of the bracket 2, and a limiting structure on the mounting plate 3; a frame 9 is provided on one side of the top of the base 1, an electric push rod 90 is provided at the top of the frame 9, a welder 91 is provided at the output end of the electric push rod 90, and a welding head 92 is provided at the output end of the welder 91. The welder 91 and the welding head 92 can be regarded as prior art.
[0019] Furthermore, the limiting structure includes a support plate 4 disposed on the surface of the mounting plate 3 and three sets of sliding supports 5 arranged in annular array on the outer periphery of the support plate 4. The sliding supports 5 have slots 50, and the bottom of the slots 50 has a sliding groove 500. A slider 51 is disposed in the sliding groove 500. A rocker arm 6 is rotatably connected to the top of the slider 51. An arc-shaped limiting block 60 is disposed at the other end of the rocker arm 6. An annular plate 7 is disposed on the top surface of the arc-shaped limiting block 60. A pin 70 is rotatably mounted between the rocker arm 6 and the annular plate 7. A fixing block 71 is disposed at the bottom of the annular plate 7, and a drive rod 72 is disposed on the fixing block 71.
[0020] Furthermore, a connecting block 74 is provided between the bottom of the annular plate 7 and the support plate 4, and the support plate 4 is rotatably connected to the mounting plate 3.
[0021] Furthermore, the length of the slide groove 500 is less than the length of the slot opening 50; this prevents the slider 51 from detaching from the slot opening 50. In this embodiment, the dimensions of the slide groove 500 and the slot opening 50 can be changed according to actual needs to accommodate the fixing of more mufflers of different sizes.
[0022] Preferably, the limiting end of the arc-shaped limiting block 60 is provided with a rubber anti-slip pad.
[0023] Furthermore, an extension plate 8 is provided on one side of the mounting plate 3, and a limiting groove is provided on the extension plate 8, and a plurality of limiting holes 80 are provided in the limiting groove; a telescopic rod 73 is provided on one side of the drive rod 72, and the telescopic rod 73 is detachably connected to the limiting holes 80.
[0024] Furthermore, the drive structure includes a motor 10, the output end of the motor 10 is provided with a lead screw 11, the lead screw 11 is provided with a moving block 12, and the top of the moving block 12 is fixedly connected to the bracket 2.
[0025] The working principle of this embodiment is as follows: The annular plate 7 is driven to rotate by the drive rod 72. Since the annular plate 7 and the support plate 4 are fixed by the connecting block 74, the support plate 4 also rotates accordingly. The annular plate 7 and the rocker arm 6 are rotatably connected by the pin 70, and the three sets of rocker arms 6 also move accordingly. The other end of the rocker arm 6 can slide in the sliding support 5. Through the rotational movement achieved by the drive rod 72, the three sets of arc-shaped limiting blocks 60 at one end of the three sets of rocker arms 6 can move closer to each other or separate from each other, thereby achieving the clamping of mufflers of different sizes. After clamping, the drive rod 72 is fixed by engaging the telescopic rod 73 on one side of the drive rod 72 with the limiting hole 80 in the limiting groove on the extension plate 8. Then, the lead screw 11 is driven to rotate by the motor 10, which causes the moving block 12 to move, thereby driving the bracket 2 and the limiting structure to approach the welding head for welding operation.
