[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , including a mounting plate 1 and a tubular component 5, the tubular component 5 includes a special-shaped structure 52, one side of the mounting plate 1 is fixedly connected to two transverse support plates 2, the top of the transverse support plate 2 is fixedly connected to a limiting frame 6, two limiting ear plates 23 and a plurality of first support frames 7, a limiting component and a fixing component are arranged on the top of the transverse support plate 2, the limiting component includes a forward and reverse motor 14, the output end of the forward and reverse motor 14 is fixedly connected to a rotating seat 16, the top of the rotating seat 16 is provided with a baffle 18, the fixing component includes a first pneumatic cylinder 8, the top of the first pneumatic cylinder 8 is provided with a rocker 10, one side of the rocker 10 is fixedly connected to a fastening rod 13, and the bottom of the fastening rod 13 is provided with a second pneumatic cylinder 21 and a docking station 22.

[0026] When the utility model is in use: two limiting ear plates 23 are fixed to the two sides of the top of the transverse support plate 2 respectively, and after the tubular component 5 is placed between the two limiting ear plates 23, the left and right displacement of the tubular component 5 is blocked and limited by the two limiting ear plates 23. At this time, the multiple first support frames 7 fixed on the top of the transverse support plate 2 are sleeved to multiple positions outside the special-shaped structure 52, and the movement of the tubular component 5 in the front and rear directions is pre-fixed while supporting and limiting the tubular component 5. At this time, the limiting frame 6 is inserted into the annular groove 53 opened on the outside of the special-shaped structure 52, and the limiting frame 6 further limits the movement of the tubular component 5 in the left and right directions, increasing the force points for limiting the left and right movement of the tubular component 5, and avoiding deformation of the position where the tubular component 5 is limited after being stressed.

[0027] A positioning frame 51 is fixedly connected to one side of the special-shaped structure 52. At this time, the positioning frame 51 is arranged between the seesaw 10 and the plug-in platform 22, and controls the second pneumatic cylinder 21 and the first pneumatic cylinder 8 fixedly connected to the top of the transverse support plate 2 to work. The second pneumatic cylinder 21 works to push the plug-in platform 22 fixed at the extension end to move upward, and a part of the upward plug-in platform 22 is inserted into the positioning frame 51. The plug-in platform 22 limits the front, back, left and right movement of the positioning frame 51, so that the tubular component 5 is limited in multiple positions when moving in one direction, ensuring that the tubular component 5 is firmly and stably clamped and fastened.

[0028] At the same time, the first pneumatic cylinder 8 pushes the transmission shaft 9 fixedly connected at the extension end to move upward.

In addition, the clamping force on the tubular component 5 is distributed at multiple positions on the outside, so as to avoid severe deformation caused by local force during processing, thereby ensuring the processing quality of the tubular component 5.
