[0026] See also Figure 1-3 The utility model provides a technical solution: a vehicle exhaust pipe processing and positioning device, comprising a base 1 and a vehicle exhaust pipe 4, four supporting legs 2 are fixedly connected to the lower surface of the base 1, a debris collection box 13 is fixedly sleeved on the base 1, and a discharge port 17 communicating with the debris collection box 13 is welded at the middle position of the lower surface of the debris collection box 13;

[0027] Among them, the front positions of the left and right sides of the base 1 are both provided with sliding grooves 15, the middle positions of the left and right sides of the base 1 are both fixedly connected with L-shaped fixing plates 11, and the L-shaped parts of the two L-shaped fixing plates 11 are both fixedly connected with dual-axis motors 12;

[0028] Among them, the two dual-axis motors 12 have front and rear output ends, and the front output ends of the two dual-axis motors 12 are fixedly connected to threaded rods 14. Both threaded rods 14 are provided with mobile positioning clamping devices, which are used to fix the automobile exhaust pipe 4.

[0029] Furthermore, the mobile positioning clamping device includes two mobile sleeves 10, which are respectively threadedly connected to the threads on the two threaded rods 14, and the opposite surfaces of the two corresponding mobile sleeves 10 are fixedly connected with sliders 16, and the two sliders 16 are respectively slidably connected in the inner walls of the two slide grooves 15.

[0030] Furthermore, the upper surfaces of the two movable sleeves 10 are fixedly connected with the second fixing plates 9, the opposite surfaces of the two corresponding second fixing plates 9 are fixedly connected with the first fixing plates 7, and the rear surface of the first fixing plates 7 is fixedly connected with the motor 6;

[0034] Furthermore, the number of the movable positioning clamping devices is two, and the two movable positioning clamping devices are arranged in front and back mirror images.

[0035] Furthermore, when using the present automobile exhaust pipe processing and positioning device, firstly, the exhaust port at the front end of the automobile exhaust pipe 4 is inserted into the outer wall of the front positioning column 20. When the two arc plates 19 contact the exhaust port at the front end of the automobile exhaust pipe 4, the four springs 23 are compressed under the action of the extrusion force and enter the exhaust port at the front end of the automobile exhaust pipe 4. Under the action of the four springs 23, the arcs of the two arc plates 19 will fit tightly with the outer wall of the exhaust port at the front end of the automobile exhaust pipe 4 until the automobile exhaust pipe 4 can no longer move. Then, the double-axis cylinder 21 located on the front side is started.

The rotation directions of the front and rear output ends of the two double-axis motors 12 are opposite. The two double-axis motors 12 drive the two threaded rods 14 to rotate. The four threaded rods 14 drive the two first fixing plates 7 to move to relative positions through the four movable sleeves 10 and the four second fixing plates 9, so that the positioning column 20 located on the rear side is inserted into the exhaust port at the rear end of the automobile exhaust pipe 4. The same is true for the front side. Then the two double-axis motors 12 are stopped, and the double-axis cylinder 21 located on the rear side is started again. The same is true for the front side. After the fixation is completed, the two motors 6 are started. The rotation directions of the two motors 6 are consistent. The two motors 6 drive the automobile exhaust pipe 4 to rotate through the two connecting shafts 18, thereby facilitating the subsequent processing of the automobile exhaust pipe 4, eliminating the need for frequent disassembly and assembly steps when processing different surfaces of the automobile exhaust pipe 4, and improving the processing efficiency of the automobile exhaust pipe 4.

[0036] Working principle: When using the automobile exhaust pipe processing and positioning device, first insert the exhaust port at the front end of the automobile exhaust pipe 4 into the outer wall of the front positioning column 20. When the two arc plates 19 contact the exhaust port at the front end of the automobile exhaust pipe 4, the four springs 23 will be compressed under the action of the extrusion force and enter the exhaust port at the front end of the automobile exhaust pipe 4. Under the action of the four springs 23, the arcs of the two arc plates 19 will fit tightly with the outer wall of the exhaust port at the front end of the automobile exhaust pipe 4 until the automobile exhaust pipe 4 can no longer move. Then start the double-axis cylinder 21 on the front side. The positioning column 20 and the two arc plates 19 play a positioning role in the installation of the automobile exhaust pipe 4. The two output ends of the double-axis cylinder 21 move to relative positions, driving the two arc clamps 3 to the automobile exhaust pipe 4. The automobile exhaust pipe 4 is fixed, and then the two double-axis motors 12 are started. The rotation directions of the front and rear output ends of the two double-axis motors 12 are opposite. The two double-axis motors 12 drive the two threaded rods 14 to rotate. The four threaded rods 14 drive the two first fixed plates 7 to move to relative positions through the four movable sleeves 10 and the four second fixed plates 9, so that the positioning column 20 located on the rear side is inserted into the exhaust port at the rear end of the automobile exhaust pipe 4, and the same as the front side. Then the two double-axis motors 12 are stopped, and the double-axis cylinder 21 located on the rear side is started again, and the same as the front side. After the fixing is completed, the two motors 6 are started. The rotation directions of the two motors 6 are consistent. The two motors 6 drive the automobile exhaust pipe 4 to rotate through the two connecting shafts 18, thereby facilitating the subsequent processing of the automobile exhaust pipe 4.
