[0002] With the widespread use of baby strollers, people have higher and higher functional requirements for baby strollers. Not only do they hope that the baby stroller can make the baby feel comfortable and safe when in use, but they also hope that the quality and stability of the stroller can be guaranteed. The stability and quality of the stroller are directly related to the quality of the stroller frame steel pipe. Therefore, when producing the stroller, the steel pipe needs to be processed specifically and cut by laser to obtain the expected finished pipe frame.

[0003] During the steel pipe cutting process, since the position of the laser head cannot be adjusted, it is necessary to adjust the position of the pipe through processing equipment to improve the steel cutting effect. However, the existing processing equipment cannot guarantee the stability of the pipe during the processing and transportation of the pipe, especially for special-shaped elliptical pipes. In addition, since the sizes of the processed pipes are different, the stability of the pipe during transportation needs to be improved. The existing special-shaped pipe processing equipment does not have clamping and positioning functions, and cannot be adjusted according to the size of the pipe to ensure stability.

[0023] Specifically, the inner end of the outlet pipe head 2 is provided with a clamping head 7, which is composed of a hydraulic rod and a semi-annular sleeve, and the semi-annular sleeve is provided at the output end of the hydraulic rod.

[0024] In this embodiment, a clamping head 7 is provided to limit and support the elliptical tube 3 output from the processing machine body 1, thereby ensuring that the elliptical tube 3 to be laser cut can be stably transported and the quality of the finished product is guaranteed.

[0025] Specifically, the clamping assembly includes a transverse clamping seat 6, a positioning hole 12, a cone wheel 13 and a positioning assembly. The transverse clamping seat 6 is movably mounted on the inner wall of the slot 8. The positioning hole 12 is opened on the outer surface of the transverse clamping seat 6. The positioning holes 12 are arranged in pairs with respect to the center line of the transverse clamping seat 6. The cone wheel 13 is movably mounted on one end of the transverse clamping seat 6. An installation opening adapted to the cone wheel 13 is opened at one end of the transverse clamping seat 6. The positioning assembly is arranged in the middle of the transverse clamping seat 6.

[0026] In this embodiment, a clamping assembly is provided to check and limit the processed elliptical tube 3, the transverse clamping seat 6 plays the role of adjusting the cone wheel 13, and the positioning hole 12 is used to cooperate with the positioning assembly, wherein the inner wall of the positioning hole 12 is provided with a threaded groove, and the position of the cone wheel 13 is realized under the insertion of the positioning assembly, thereby ensuring that the processed elliptical tube 3 can stably run along the inner side of the cone wheel 13.

[0027] Specifically, the positioning assembly includes a collar 10 , a positioning pin 9 , and a rocker 11 . The collar 10 is disposed in the middle of the transverse clamping seat 6 , the positioning pin 9 is movably mounted on the inner wall of the collar 10 , and the rocker 11 is fixedly mounted on the outer side of the collar 10 .

[0028] In the present embodiment, the collar 10 is used to drive the positioning pin 9 so that the positioning pin 9 expands outward, thereby being plugged into the positioning hole 12 to ensure the positioning of the transverse clamping seat 6, wherein the collar 10 is driven by moving the rocker 11 back and forth, wherein the positioning pin 9 is provided with two groups, and when the positioning pin 9 needs to be disassembled, the collar 10 is directly taken out from the positioning pin 9.

[0029] Specifically, a groove is formed on the outer side of the positioning pin 9 , and a spring bevel block 15 is provided on the inner wall of the groove. A bevel is formed on one end of the spring bevel block 15 .

[0030] In this embodiment, a groove is provided on the outer side of the positioning pin 9 to install the spring bevel 15 , and the spring bevel 15 is used to cooperate with the pressing teeth 14 provided on the inner side of the collar 10 , thereby realizing the driving of the positioning pin 9 .

[0032] In the present embodiment, the pressing tooth 14 is driven to rotate along the bevel of the outer end of the spring bevel block 15 by rotating the collar 10 counterclockwise. At this time, the spring bevel block 15 is squeezed and contracts along the groove. When the collar 10 is rotated clockwise, the pressing tooth 14 will engage with the spring bevel block 15, thereby driving the locating pin 9 to rotate. Since the two ends of the locating pin 9 are provided with threads 16 in opposite directions and cooperate with the thread grooves inside the locating hole 12, the locating pin 9 will move outward along the inner wall of the collar 10 and then engage with the locating hole 12, thereby realizing the positioning of the horizontal clamping seat 6.

Before processing the oval tube 3, the transverse clamping seat 6 is inserted into the appropriate position along the inner wall of the slot 8, that is, the clamping position during the processing of the oval tube 3 is met, and then the pressing tooth 14 is driven to rotate along the bevel of the outer end of the spring inclined block 15 by rotating the collar 10 counterclockwise. At this time, the spring inclined block 15 is squeezed and contracts along the groove. When the spring inclined block 15 is rotated counterclockwise, the pressing tooth 14 is driven to rotate along the bevel of the outer end of the spring inclined block 15. When the hour hand rotates the collar 10, the pressing tooth 14 will engage with the spring bevel 15, thereby driving the positioning pin 9 to rotate. Since the two ends of the positioning pin 9 are provided with threads 16 in opposite directions and cooperate with the thread grooves inside the positioning hole 12, the positioning pin 9 will move outward along the inner wall of the collar 10 and then engage with the positioning hole 12, thereby realizing the positioning of the horizontal clamping seat 6. Since the elliptical tube 3 is in the process of being conveyed by the processing body 1, the mounting seat 5 can be laterally gathered under the drive of the processing body 1, and the side of the elliptical tube 3 will be pressed against the inner side of the cone wheel 13, thereby realizing the positioning of the elliptical tube 3.
