This rise causes the vertical rod to rise, locking into the collar and immediately stopping the worktable's rotation. During the counterclockwise rotation of the worktable, the material rotates, and the immediate stop of rotation creates a tearing effect on the material due to inertia. This inertia is used to test the material's strength after welding, effectively checking for weld weakness and improving the workpiece's pass rate.

[0023] 3. This dual-gun ring welding machine for automotive mufflers utilizes a worktable to rotate a baffle. When the gravity plate rotates to the position of the vertical plate, the vertical plate lifts the gravity plate, causing the striking plate to rise. Then, when the striking plate falls, it impacts the material to test its firmness. Combined with the material testing during the worktable process, the machine tests the material's firmness from different aspects, ensuring the accuracy of the material testing.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0036] Example 1, please refer to Figures 1-5The present invention provides a technical solution: a dual-gun ring welding machine for automotive welding mufflers, comprising a control device 1, a platform 2 fixedly connected to the top of the control device 1, a dual-gun welding device 4 fixedly connected to the outer wall of the control device 1, a placement plate 3 fixedly connected to the top of the platform 2, and a back-jet mechanism 7 fixedly connected to the inner wall of the control device 1.

[0037] The recoil mechanism 7 includes:

[0038] The first bearing 72 has holes on the outer wall of the placement plate 3 and the top of the control device 1, and the first bearing 72 is fixedly connected in the holes of the placement plate 3.

[0039] The worktable 71 is rotatably connected to the outer wall of the first bearing 72.

[0040] A round rod 73 is fixedly connected to the bottom of the workbench 71. A movable rod 6 is rotatably connected to the top of the workbench 71. A baffle 5 is fixedly connected to the top of the workbench 71.

[0041] A motor 712 is fixedly connected to the bottom of the control device 1, and a rotating shaft 76 is rotatably connected to the top of the motor 712.

[0042] A threaded rod 75 is fixedly connected to the top of the rotating shaft 76, and a first spring 74 is fixedly connected to the top of the threaded rod 75.

[0043] The top of the first spring 74 is fixedly connected to a collar 77, and the top of the collar 77 is fixedly connected to the bottom of the round rod 73.

[0044] The inner wall of the control device 1 is fixedly connected to a slide rail 79, and the inner wall of the slide rail 79 is slidably connected to a slider 710. The slider 710 is also sleeved on the outer wall of the rotating shaft 76. The inner wall of the slider 710 is provided with threads, and the slider 710 is in active contact with the threaded rod 75.

[0045] A vertical rod 78 is fixedly connected to the top of the slider 710, and the vertical rod 78 is inserted into the collar 77. A second spring 711 is fixedly connected between the bottom of the slider 710 and the inner wall of the control device 1.

[0046] The top of the workbench 71 is fixedly connected to a third bearing 11, the top of the third bearing 11 is rotatably connected to a first clamping plate 10, and the top of the first clamping plate 10 is threadedly connected to a first bolt 9.

[0047] A sliding rod 12 is fixedly connected to the outer wall of the baffle 5. A sliding block 13 is slidably connected to the outer wall of the sliding rod 12. A third bolt 16 is threadedly connected to the outer wall of the sliding block 13. A second clamping plate 14 is fixedly connected to the top of the sliding block 13. A second bolt 15 is threadedly connected to the top of the second clamping plate 14.

[0048] In use, the control device 1 can control the operation of each device. The material to be welded is placed on the workbench 71. One side of the welding material is placed in the first clamping plate 10. Then the first bolt 9 is rotated to fix the material. The other side of the material is placed in the second clamping plate 14. The sliding block 13 is located on the slide rod 12 and can move. Then the second clamping plate 14 is pressed onto the material. Finally, the third bolt 16 is tightened to fix the sliding block 13. The second bolt 15 is rotated to fix the material in the second clamping plate 14. Then the double-gun welding device 4 is picked up to weld the material.

[0049] After welding is completed, combine with the attached Figure 8 As shown, rotating loosens the second bolt 15 and the third bolt 16, pushes the sliding block 13, and thus moves the second clamping plate 14 away from the material, so that the material will not collide with the second clamping plate 14 during the shaking process.

[0050] Combined with appendix Figure 5 As shown, when the motor 712 is powered on and started, the motor 712 drives the threaded rod 75 to rotate through the rotating shaft 76. The threaded rod 75 is spiral upward. When the threaded rod 75 rotates counterclockwise, it pulls the worktable 71 on the round rod 73 to rotate through the first spring 74. When the worktable 71 rotates, it will drive the material to rotate as well. The rotation of the material is used to test the firmness of the material under the pull of its centrifugal force.

[0051] Combined with appendix Figure 5 and 7 As shown, the first clamping plate 10 fixes one side of the material, and the third bearing 11 allows the material to rotate. The motor 712 drives the threaded rod 75 to rotate counterclockwise once, and then immediately rotates clockwise once. The elastic length of the second spring 711 is greater than the distance between the slide rail 79 and the inner wall of the control device 1. Therefore, under the compression of the second spring 711, the slider 710 continues to adhere to the threaded rod 75. When the threaded rod 75 rotates counterclockwise, the threads of the threaded rod 75 and the inner wall of the slider 710 are opposite. When the threaded rod 75 rotates clockwise, the threaded rod 75 is threadedly connected to the slider 710, which will drive the slider 710 to rise on the slide rail 79. At this time, the vertical rod 78 will rise. The vertical rod 78 rises and gets stuck in the collar 77, which will immediately stop the rotation of the worktable 71. During the counterclockwise rotation of the worktable 71, the material is rotated. Then the rotation stops immediately. Under inertia, the material will be torn, thereby testing the firmness of the material.

[0052] Subsequently, the motor 712 drives the threaded rod 75 to rotate counterclockwise again, which will cause the slider 710 to descend on the threaded rod 75.

[0053] Example 3, please refer to Figures 1-9 Based on Embodiment 1 and Embodiment 2, the present invention provides a technical solution:

[0054] A striking mechanism 8 is fixedly connected to the outer wall of the baffle 5. The striking mechanism 8 includes a second bearing 81. The outer wall of the second bearing 81 is rotatably connected to the second bearing 81, and a striking plate 82 is rotatably connected to the outer wall of the second bearing 81.

[0055] A connecting rod 83 is fixedly connected to the outer wall of the striking plate 82, and a gravity plate 84 is fixedly connected to the outer wall of the connecting rod 83. A vertical plate 85 is fixedly connected to the top of the workbench 71, and the gravity plate 84 and the vertical plate 85 are in contact.

[0056] In use, the striking plate 82 is normally in a hanging position. When the workbench 71 drives the baffle 5 to rotate, the gravity plate 84 rotates to the position of the vertical plate 85. The vertical plate 85 lifts the gravity plate 84, which in turn drives the striking plate 82 to rise. Then, when the striking plate 82 falls, it hits the material to test the material's firmness. The repeated cyclic rotation of the workbench 71 will cause the gravity plate 84 to repeatedly collide with the vertical plate 85.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
