Description

Technical Field

[0001] This utility model relates to the field of exhaust pipe fixing technology, and in particular to an exhaust pipe positioning device. Background Technology

[0002] The exhaust pipe is an important component of internal combustion engine power equipment such as automobiles and motorcycles. It is mainly used to vent the exhaust gas produced by engine combustion from the cylinder to the atmosphere. It can reduce the noise of exhaust gas emission through the muffler. At the same time, some models have integrated catalytic converters in their exhaust pipes to purify harmful substances in the exhaust gas, thus playing an environmental protection role.

[0003] The manufacturing process of exhaust pipes typically begins with cutting the raw materials. After the metal pipes are cut to size, they are bent into the designed arc using a pipe bending machine. Next, the pipe ends are shaped by flaring and shrinking to fit the connecting components. Then, components such as flanges and mufflers are welded to form a complete pipeline. After that, the welding slag is removed by grinding, and some products also undergo surface treatments such as pickling and electroplating to improve corrosion resistance. Finally, the sealing performance is checked through pressure testing to ensure that it meets the usage standards.

[0004] Most existing exhaust pipe positioning devices use bolts for positioning. When positioning exhaust pipes of different sizes, adjusting and replacing bolts is cumbersome, resulting in low fixing efficiency. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the fact that most existing exhaust pipe positioning devices use bolts for positioning. When positioning exhaust pipes of different sizes, adjusting and replacing bolts is cumbersome, resulting in low fixing efficiency.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] Reference Figures 1 to 5 As shown, this utility model discloses a positioning device for an exhaust pipe, comprising a worktable 1, a lifting platform 11 fixedly connected to the top of the worktable 1; a placement platform 12 fixedly connected to the top of the lifting platform 11; a pair of support rods 13 fixedly connected to the top of the worktable 1; the support rods 13 are symmetrically arranged at the top of the worktable 1; electric push rods 14 fixedly connected to the top of the support rods 13; a push plate 15 fixedly connected to the output end of the electric push rods 14; a support frame 16 fixedly connected to the top of the worktable 1; and a processing tool 17 fixedly connected to the top of the support frame 16. During operation, the exhaust pipe to be processed is placed on the top of the placement platform 12. Then, the lifting platform 11 is adjusted to adjust the overall height of the placement platform 12. After adjusting the height of the placement platform 12, the pair of electric push rods 14 at the top of the support rods 13 can be activated, causing the push plate 15 to move closer to the worktable. Near the side of the exhaust pipe, the exhaust pipe is positioned on the top of the placement platform 12, forming a three-point positioning. When dealing with exhaust pipes of different sizes, only the height of the placement platform 12 needs to be adjusted to position the exhaust pipe. After the exhaust pipe is fixed on the top of the placement platform 12, the processing cutter 17 can be activated to approach the exhaust pipe and process it. The three-point positioning is formed by the support on the top of the placement platform 12 and the clamping from the side by a pair of push plates 15. This can apply a fixing force to the exhaust pipe from different directions, reducing the shaking and displacement caused by the force during processing, which leads to deviation in the processing position. This ensures that the exhaust pipe is always in the preset position during processing, reducing the problem of easy loosening of two-point fixation. The positioning can be completed by adjusting the height of the lifting platform 11 and activating the electric push rod 14 to drive the push plate 15. This reduces the inconvenience caused by repeatedly turning the bolts during fixing and increases the convenience of clamping.

At this time, the telescopic sleeve 21 can be pushed to the placement platform 12, and then a pulling force can be applied to the top plate 22 to adjust the top plate 22 to be parallel with the placement platform 12, and the pin 23 can be inserted into the top plate 22. In the middle, connected to the side of the placement platform 12, the top plate 22 is fixed. The top plate 22 can support the longer end of the exhaust pipe. The slot on the side of the placement platform 12 can also adjust the support position of the telescopic sleeve 21 according to the different shapes of the exhaust pipe. The top plate 22 can provide effective support for the longer end, which can reduce the bending of the exhaust pipe due to uneven force and increase the integrity of the exhaust pipe during the processing. The slot on the side of the placement platform 12 can be adjusted in conjunction with the position of the telescopic sleeve 21, so that the top plate 22 can be flexibly changed according to the different shapes of the exhaust pipe, thereby improving the stability of the support.

[0028] Reference Figure 1 and Figure 4 As shown, an air pump 4 is fixedly connected to the top of the support frame 16; an air jet port 41 is fixedly connected to the side wall of the air pump 4; during operation, when the processing cutter 17 is processing the exhaust pipe, the debris will fall onto the top of the placement table 12. At this time, the air pump 4 can be started, and the airflow will be ejected from the air jet port 41 to blow away the debris on the top of the placement table 12 and the top of the exhaust pipe; the airflow ejected through the air jet port 41 can promptly blow away the debris on the top of the placement table 12 and the surface of the exhaust pipe, reducing the friction between the accumulated debris and the surface of the exhaust pipe.

The pull-out box 51 is slidably connected to the side wall of the collection trough 5, and the debris can be taken out and dumped simply by pulling the pull-out box 51, increasing the convenience of debris handling.

[0030] Reference Figure 5 As shown, a baffle plate 6 is fixedly connected to the top of the workbench 1; the baffle plate 6 is correspondingly arranged with the collection tank 5; during operation, the baffle plate 6 can further block the debris blown by the air jet 41, and block the debris to fall inside the collection tank 5; the baffle plate 6 can block the debris blown by the airflow, reduce the debris from being blown to the outside of the collection tank 5 by the airflow, increase the debris collection effect, and reduce debris leakage.

[0031] Reference Figure 1 and Figure 3 As shown, a first flexible pad 7 is fixedly connected to the top of the placement platform 12; a first flexible pad 7 is fixedly connected to the top of the top plate 22; and a second flexible pad 71 is fixedly connected to the top of the clamping plate 31. During operation, the first flexible pad 7 on the top of the placement platform 12 and the top plate 22 can protect the surface of the exhaust pipe, ensuring good surface quality during processing. The second flexible pad 71 on the top of the clamping plate 31 can further buffer the squeezing force of the electric push rod 14. Through the contact between the first flexible pad 7 and the second flexible pad 71 and the exhaust pipe, the direct friction and collision between the surface of the exhaust pipe and the device can be reduced, thus preventing scratches from appearing on the surface of the exhaust pipe.

[0032] Reference Figure 5 As shown, a sponge pad 8 is fixed to the bottom of the pull-out box 51; the sponge pad 8 is correspondingly arranged with the pull-out box 51; during operation, when debris falls into the collection tank 5, it can come into contact with the sponge pad 8, and then the sponge pad 8 cushions the falling debris; through the cushioning effect of the sponge pad 8, the impact force when the debris falls can be reduced, and the debris can be reduced from bouncing and splashing when it comes into contact with the bottom of the collection tank 5.

[0033] Working principle: Place the exhaust pipe to be processed on top of the placement platform 12. Then adjust the overall height of the placement platform 12 by pushing the lifting platform 11. After adjusting the height of the placement platform 12, activate the pair of electric push rods 14 on top of the support rod 13. The electric push rods 14 will drive the push plate 15 to move closer to the side of the exhaust pipe, positioning the exhaust pipe on top of the placement platform 12, forming a three-point positioning. When dealing with exhaust pipes of different sizes, simply adjust the height of the placement platform 12 to position the exhaust pipe. Once the exhaust pipe is fixed on top of the placement platform 12, the machining process can be started. The tool 17 is brought close to the exhaust pipe to process it. When the exhaust pipe is long, the longer end will sag due to its own weight. At this time, the telescopic sleeve 21 can be pushed to the placement platform 12. Then, a pulling force is applied to the top plate 22 to adjust it to be parallel to the placement platform 12. The pin 23 is inserted into the middle of the top plate 22 and connected to the side of the placement platform 12 to fix the top plate 22. The top plate 22 can support the longer end of the exhaust pipe. The slot on the side of the placement platform 12 can also adjust the telescopic sleeve according to the different shapes of the exhaust pipe. At the support position of 21, when the push plate 15 presses and fixes the exhaust pipe on the top of the placement table 12, the damping spring telescopic rod 3 can retract due to the thrust of the electric push rod 14, causing the clamping plate 31 to contact the side wall of the exhaust pipe, thus buffering the thrust of the electric push rod 14. When the machining cutter 17 is machining the exhaust pipe, the debris will fall onto the top of the placement table 12. At this time, the air pump 4 can be started, and the airflow will be sprayed out from the jet nozzle 41 to blow away the debris on the top of the placement table 12 and the top of the exhaust pipe. The debris blown by the jet nozzle 41 can fall into the collection tank 5 for debris collection. After a certain amount of debris is collected inside the collection tank 5, the pull-out box 51 can be pulled out and dumped. The baffle plate 6 can further block the debris blown by the jet nozzle 41, keeping the debris inside the collection tank 5. The first flexible pad 7 on the top of the placement platform 12 and the top plate 22 can protect the surface of the exhaust pipe, ensuring good surface quality during processing. The second flexible pad 71 on the top of the clamping plate 31 can further buffer the squeezing force of the electric push rod 14. When the debris falls into the collection tank 5, it can come into contact with the sponge pad 8, which then cushions the falling debris.

[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
