[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0017] like Figs. 1-2 As shown, a positioning device for processing automotive exhaust pipes includes a base 1, an arc-shaped groove 2, and two sets of arc-shaped supports 3. The arc-shaped groove 2 is located on the upper side of the base 1, and the lower sides of the two sets of arc-shaped supports 3 are located on the front and rear sides of the arc-shaped groove 2, respectively. The axial direction of the two sets of arc-shaped supports 3 is parallel to the axial direction of the arc-shaped groove 2. The upper side of the base 1, located on the front and rear sides of the arc-shaped groove 2, is provided with sliding grooves 4. The interiors of the two sets of sliding grooves 4 are respectively connected to the lower sides of the two sets of arc-shaped supports 3 with displacement mechanisms. Two sets of hydraulic pipes 10 are inserted and connected to the inner walls on both sides of the arc-shaped supports 3. A liquid storage tank is passed through and connected to the upper side of the arc-shaped supports 3. 9. Hydraulic pump bodies 11 are respectively provided on the inner side of the arc-shaped frame 3 and on both sides of the liquid storage tank 9. One end of the hydraulic pump body 11 is connected to the lower side of the liquid storage tank 9, and the other end is connected to a liquid guide pipe 12. The liquid guide pipe 12 is connected to two sets of hydraulic pipes 10 on the same side. An arc-shaped clamping block 13 is connected to the lower end of one set of hydraulic pipes 10 on the same side, and a limiting slider 15 is connected to the other set of hydraulic pipes 10 on the same side. A limiting groove 14 is provided on the side of the arc-shaped clamping block 13 near the hydraulic pipe 10 to cooperate with the limiting slider 15. A control switch 16 is connected to the right side wall of the base 1.

[0018] Place the car exhaust pipe inside the arc-shaped groove 2 and adjust its position. Adjust the position of the two sets of arc-shaped brackets 3 through the displacement mechanism so that the position of the car exhaust pipe to be operated is exposed, which facilitates the operation of the car exhaust pipe later. Simultaneously start the two sets of hydraulic pumps 11 through the control switch 16. The hydraulic pumps 11 send the oil in the reservoir 9 to the hydraulic pipe 10 through the guide pipe 12, so that the hydraulic pipe 10 extends and pushes the two sets of arc-shaped clamps 13 to the upper part of the car exhaust pipe. The car exhaust pipe is positioned by cooperating with the arc-shaped groove 2.

[0019] The inner wall of the arc-shaped groove 2 is connected to a rubber pad 17, and multiple sets of miniature pressure sensors 18 are provided inside the rubber pad 17. The middle part of the base 1 is provided with a cavity 19, and the cavity 19 is provided with a control box 20. A warning light 21 is connected to the upper right side of the base 1.

[0020] The pressure generated downward by the car exhaust pipe is detected by the miniature pressure sensor 18 inside the rubber pad 17. When the pressure value is the same as the set standard pressure value, the signal is transmitted to the control box 20. The control box 20 sends the signal to the warning light 21 and the two sets of hydraulic pumps 11. The warning light 21 provides an alert, causing the two sets of hydraulic pumps 11 to stop working and keeping the extension length of the hydraulic pipe 10 unchanged, so that the car exhaust pipe can be positioned well and will not be deformed.

[0021] The displacement mechanism includes a threaded shaft 5 rotatably connected between the left and right side walls of the slide 4. Two sets of nuts 7 are respectively connected to the outer sides of the threaded shaft 5. The lower side of the arc frame 3 passes through the interior of the slide 4 and is connected to the upper side of the two sets of nuts 7 on the same side. Motors 6 are respectively connected to the front and rear parts of the left side wall of the base 1. The threaded shaft 5 rotatably passes through the base 1 and is connected to the shaft end of the motor 6. The threads on the outer sides of the threaded shaft 5 are opposite in direction. Limiting strips 8 that limit the lower side of the arc frame 3 are respectively connected to the edge of the upper inner wall of the slide 4. When the arc frame 3 needs to move, the two sets of motors 6 are started simultaneously by the control switch 16. The motors 6 drive the threaded shaft 5 to rotate, and the threaded shaft 5 drives the nuts 7 on the outer sides to move closer or further away at the same time. This drives the two sets of arc frames 3 to move closer or further away at the same time, adjusting the two sets of arc frames 3 to a suitable position.

[0022] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
