[0023] Please see Figure 1-5 This utility model provides a technical solution: a positioning and welding mechanism for automotive exhaust pipe components, comprising: a fixing plate 1, four support legs 2 and four support legs 3 fixedly connected to both sides of the bottom of the fixing plate 1, a fixing base plate 4 fixedly connected to the bottom of the four support legs 2 and four support legs 3, an mounting plate 5 fixedly connected to one side of the fixing plate 1 and the fixing base plate 4, a control terminal 6 fixedly mounted on the other side of the mounting plate 5, clamping bases 7 fixedly connected to both ends of the top of the fixing plate 1, clamping mechanisms 8 provided at both ends of the top of the fixing base plate 4, and exhaust pipe components 9 fixedly embedded on the inner side of the two clamping mechanisms 8.

[0024] Specifically: The device connects to an external power supply via a line to provide power to the internal electrical components, and is controlled by a control terminal 6. Support legs 1 and 2 cooperate to support and fix the fixing plate 1. The fixing base plate 4 is used to support and fix the device components. The clamping mechanism 8 is used to clamp and fix the exhaust pipe 9 in conjunction with the clamping base 7.

[0025] In one embodiment, the clamping mechanism 8 includes a drive cylinder 801, which is fixedly connected to one side of the top of the fixed base plate 4. The output end of the drive cylinder 801 is fixedly connected to a U-shaped plate 802, and the other end of the inner side of the U-shaped plate 802 is rotatably mounted with a rotating shaft 803 through a bearing.

[0026] Specifically, such as Figure 1 , 2 As shown: The output end of the drive cylinder 801 extends and retracts, causing the U-shaped plate 802 to move back and forth. The rotating shaft 803 is used to limit the movement of the bottom of the connecting plate 804.

[0027] In one embodiment, a connecting plate 804 is fixedly sleeved on the surface of the first rotating shaft 803. A movable groove 8041 is provided in the middle of both sides of the connecting plate 804. A second rotating shaft 805 is movably embedded in the interior of each of the two movable grooves 8041. The other ends of the two second rotating shafts 805 are rotatably connected to a fixed connecting plate 806 through bearings. An L-shaped fixed plate 807 is fixedly connected to the other ends of the two fixed connecting plates 806.

[0028] Specifically, such as Figure 1 , 2 As shown: the second rotating shaft 805 is used to limit the movement of the middle part of the connecting plate 804, the fixed connecting plate 806 is used to fix the second rotating shaft 805, the L-shaped fixed plate 807 is used to connect and fix the two fixed connecting plates 806, and the movable groove 8041 is used to provide the second rotating shaft 805 with movement space when the connecting plate 804 is flipped and rotated.

[0029] In one embodiment, the other side of the L-shaped fixing plate 807 is movably fitted to one side of the clamping base 7 and the bottom of the fixing plate 1. Six fixing bolts 10 are movably embedded through the surface of the L-shaped fixing plate 807, and the other ends of two fixing bolts 10 are respectively threaded into the two ends of one side of the surface of the clamping base 7.

[0030] Specifically, such as Figure 2 , 3 As shown in Figure 4: the fixing bolt 10 is used to install and fix the L-shaped fixing plate 807, and the two fixing bolts 10 at the top are used to install and fix the top of the L-shaped fixing plate 807.

[0031] In one embodiment, the other ends of the other two fixing bolts 10 are respectively threaded into both ends of one side of the fixing plate 1.

[0032] Specifically, such as Figure 2 , 3 As shown in Figure 4: The two fixing bolts 10 in the middle are used to install and fix the middle part of the L-shaped fixing plate 807.

[0033] In one embodiment, the other ends of the two bottommost fixing bolts 10 are threaded into the two ends of the bottom side of the fixing plate 1, respectively.

[0034] Specifically, such as Figure 2 , 3 As shown in Figure 4: The two fixing bolts 10 at the bottom are used to fix the bottom of the L-shaped fixing plate 807 to one side of the bottom of the fixing plate 1. The six fixing bolts 10 work together to reinforce and fix the L-shaped fixing plate 807, minimizing the chance of loosening.

[0035] In one embodiment, a mounting plate 808 is fixedly connected to the top of the other side of the connecting plate 804, and an auxiliary clamping seat 809 is fixedly connected to the bottom of the mounting plate 808. The exhaust pipe 9 is movably embedded between the auxiliary clamping seat 809 and the opposite side of the clamping base 7.

[0036] Specifically, such as Figure 1 , 3 As shown in Figure 4: When the output end of the drive cylinder 801 retracts, the bottom of the connecting plate 804 tilts and rotates outward around the surface of the first rotating shaft 803. At the same time, the bottom of the connecting plate 804 moves towards one end of the drive cylinder 801, the second rotating shaft 805 moves upward along the interior of the movable groove 8041, the top of the connecting plate 804 flips outward, releasing the clamping of the exhaust pipe 9, the output end of the drive cylinder 801 extends, the bottom of the connecting plate 804 rotates inward around the surface of the first rotating shaft 803, at the same time, the bottom of the connecting plate 804 moves outward, the second rotating shaft 805 moves downward along the interior of the movable groove 8041, the top of the connecting plate 804 flips inward, clamping and fixing the exhaust pipe 9.

[0037] Working principle: When using this device to clamp and fix automobile exhaust pipe parts for positioning welding, firstly, operate the control terminal 6. When the output end of the drive cylinder 801 is retracted by the control terminal 6, the bottom of the connecting plate 804 tilts and rotates outward around the surface of the first rotating shaft 803. At the same time, the bottom of the connecting plate 804 moves towards one end of the drive cylinder 801, the second rotating shaft 805 moves upward along the inside of the movable groove 8041, and the top of the connecting plate 804 flips outward, increasing the distance between the auxiliary clamping seat 809 and the clamping base 7. Then, another worker places the exhaust pipe part 9 on the inner side of the top of the clamping base 7.

[0038] Then, the control terminal 6 is operated. The control terminal 6 controls the output end of the drive cylinder 801 to extend, the bottom of the connecting plate 804 rotates inward around the surface of the first rotating shaft 803, and at the same time, the bottom of the connecting plate 804 moves outward. The second rotating shaft 805 moves downward along the inside of the movable groove 8041, and the top of the connecting plate 804 flips inward. The auxiliary clamping seat 809 and the clamping base 7 clamp and fix the exhaust pipe 9. Finally, two workers use external welding equipment to weld the two sides of the surface of the exhaust pipe 9.

[0039] With this setup, it is easy to clamp and fix the exhaust pipe 9 during positioning welding operations;

[0040] When maintenance is required on the equipment, the six fixing bolts 10 are removed one by one from top to bottom. Then, the surface of the connecting plate 804 is held and rotated outwards. Then, lubrication and maintenance can be applied to each connecting part.

[0041] With this design, the device has a simple structure and is easy to operate and maintain.
