Description

Technical Field

[0001] The utility model relates to the technical field of positioning devices, and more specifically, to a positioning device for exhaust pipe welding. Background Art

[0002] In the existing technology, the existing positioning device cannot fully and reliably fix the exhaust pipe. The exhaust pipe needs to maintain a stable and accurate position during the welding process to ensure the quality and consistency of the weld. However, the current device has limitations when fixing the exhaust pipe, especially for exhaust pipes of different lengths and sizes. The existing device is difficult to provide a flexible and adjustable fixing method, which causes the exhaust pipe to be easily displaced or vibrated during the welding process, affecting the welding quality and may even cause weld defects or deformation.

[0003] However, many existing exhaust pipe welding positioning devices do not fully consider the needs of cable fixation during design. They may only focus on the positioning and clamping of the exhaust pipe, but ignore the necessity of reasonable arrangement and reliable fixation of the cables. The lack of dedicated cable fixing components makes the management and protection of cables completely dependent on the operator's experience and on-the-spot adaptability, making it difficult to achieve standardization and normalization.

[0004] In addition, after clamping the exhaust pipe, the existing device cannot flexibly adjust the angle and position of the exhaust pipe. In the actual welding process, the welding angle and position between the exhaust pipe and other components are related to the quality of the weld and the assembly accuracy of the exhaust system. However, after clamping the exhaust pipe, many existing devices have fixed angles and positions and cannot be fine-tuned or adjusted at multiple angles. This inflexible design limits the optimization space of the welding process and may result in unstable weld quality or difficulty in assembly. Utility Model Content

[0035] In the present embodiment, when the exhaust pipe needs to be clamped and fixed during use, the rotating assembly is manually adjusted to a position where the fixing disk 25 and the fixing plate 5 are parallel. At this time, the fixing seat 2 is manually pushed so that the moving wheel 7 at the bottom thereof is used to slide along the bottom plate 1. After it slides to a suitable position, the threaded rod 8 at the bottom of the fixing seat 2 is manually rotated to drive the suction cup 12 to move to a position in contact with the bottom plate 1, so that the suction cup 12 is used to complete the fixing process of the fixing seat 2. At this time, one end of the exhaust pipe is manually moved to the fixing disk 25, and the bidirectional screw 26 is manually rotated in the opposite direction to drive the fixing block 27 to move along the fixing disk 25.

At this time, the moving block 14 is released, so that under the action of the tension spring 16, the sliding rod 15 is driven to slide to the initial position, thereby driving the elastic sheet 13 to move under the cooperation of the moving block 14, so that the fixed wire block 11 is slid along the inside of the fixed wire tube 10. Move the process to restore it to Figure 5 The position shown in the figure completes the fixing process of the cable. When the cable needs to be taken out, the above operation is repeated to drive the moving block 14 to move, thereby releasing the fixing of the cable and manually taking out the cable.

[0040] More specifically, after the exhaust pipe is fixed, when the angle of the exhaust pipe needs to be adjusted, the drive motor 18 is manually started to drive the output end driving gear 19 to rotate, thereby driving the driven gear 21 meshing with it to rotate, so that it rotates on the rotating shaft 20 on the fixed frame 17, and then drives the rotating gears 22 at both ends of the rotating shaft 20 to rotate, thereby driving the half gear 24 to rotate, and driving the rotating seat 23 to rotate along the top of the fixed frame 17, thereby completing the angle adjustment process for one end of the fixed exhaust pipe.

[0041] In summary, when the overall equipment is in use or running: during use, when the exhaust pipe needs to be clamped and fixed, the rotating assembly is manually adjusted to a position where the fixing disk 25 and the fixing plate 5 are parallel. At this time, the fixing seat 2 is manually pushed so that the moving wheel 7 at the bottom thereof is used to slide along the bottom plate 1. After it slides to the appropriate position, the threaded rod 8 at the bottom of the fixing seat 2 is manually rotated to drive the suction cup 12 to move to a position that fits the bottom plate 1, so that the suction cup 12 is used to complete the fixing process of the fixing seat 2. At this time, one end of the exhaust pipe is manually moved to the fixing disk 25, so that the bidirectional screw 26 is manually reversed to drive the fixing block 27 to move along the fixing disk 25. When the exhaust pipe can be released, the bidirectional screw 26 is manually reversed to drive the fixing block 27 to move in the opposite direction, so that the fixing process of one end of the exhaust pipe is completed by the fixing block 27, and the exhaust pipe The other end of the cable is fitted with the fixing plate 5, so that the rubber plate 6 can be fitted at the pipe mouth of the exhaust pipe, so that the fixing process of the exhaust pipe is completed. When it is necessary to fix the cable, the moving block 14 is manually pulled to stretch the tension spring 16 on the sliding rod 15, thereby driving the sliding rod 15 to slide along the two ends of the fixed wire tube 10, thereby driving the movement process of the elastic sheet 13, and further driving the fixed wire block 11 to slide inside the fixed wire tube 10. When it fully stretches the tension spring 16, the cable is manually introduced into the fixed wire tube 10 from one end of the moving block 14, and then led out from the other end of the fixed wire tube 10. At this time, the moving block 14 is released, so that under the action of the tension spring 16, the sliding rod 15 is driven to slide to the initial position, thereby driving the elastic sheet 13 to move under the cooperation of the moving block 14, so that the fixed wire block 11 is slid along the inside of the fixed wire tube 10. Move the process to restore it to Figure 5 The position shown in the figure completes the fixing process of the cable. When the cable needs to be taken out, the above operation is repeated to drive the moving block 14 to move, thereby releasing the fixing of the cable and manually taking out the cable.

[0042] After the exhaust pipe is fixed, when the angle of the exhaust pipe needs to be adjusted, the driving motor 18 is manually started to drive the output end driving gear 19 to rotate, thereby driving the driven gear 21 meshing with it to rotate, so that it rotates on the rotating shaft 20 on the fixed frame 17, and then drives the rotating gears 22 at both ends of the rotating shaft 20 to rotate, thereby driving the half gear 24 to rotate, and driving the rotating seat 23 to rotate along the top of the fixed frame 17, thereby completing the angle adjustment process for one end of the fixed exhaust pipe. When adjusting the angle of one end of the exhaust pipe, the cylinder 3 is manually started to drive the output end to drive the articulated seat 4 to move in height. When the exhaust pipe is tilted, the rubber plate 6 on the fixed plate 5 is used to make it fit closely with one end of the exhaust pipe, and cooperate with the rotation process of the articulated seat 4 to complete the rotation adjustment process of the exhaust pipe.
