[0039] As Figures 2 to 3 shown, a plurality of uniformly distributed fixed ear plates 306 are integrally formed at the bottom of the clamping bottom plate 301. The clamping bottom plate 301 is assembled and fixed by assembling and fixing the plurality of fixed ear plates 306. Assembly bolts 307 are threadedly connected between the plurality of fixed ear plates 306 and the bearing tray 203. The fixed ear plates 306 are fixedly assembled above the bearing tray 203 through the assembly bolts 307.

[0040] As Figures 2 to 5 shown, an inner top column 302 is fixedly assembled above the clamping bottom plate 301. The inner top column 302 provides inner support for the pipe-type automotive parts, providing a basis for subsequent clamping of the pipe-type automotive parts.

[0041] As Figures 4 to 5 shown, a fixing bolt 314 is fixedly connected between the inner top column 302 and the clamping bottom plate 301. The fixing bolt 314 penetrates through the inner top column 302 and is threadedly connected to the clamping bottom plate 301. The inner top column 302 is assembled above the bearing tray 203 through the threaded fit of the fixing bolt 314 and the inner top column 302.

[0042] As Figures 4 to 5 shown, multiple groups of pneumatic control boxes 303 are fixedly assembled on the outer side of the inner top column 302. The pneumatic control boxes 303 play a role in receiving, limiting, and moving control of the inner top block 304.

[0043] As Figures 4 to 5 shown, inner top blocks 304 are slidably assembled in multiple groups of pneumatic control boxes 303. The inner walls of the pipe-type automotive parts are limited by the ejection of multiple groups of inner top blocks 304.

[0044] As Figures 4 to 5 shown, multiple groups of connecting springs 313 are fixedly connected between the inner top blocks 304 and the pneumatic control boxes 303. The conducting air pipes 312 are arranged between the inner top blocks 304 and the pneumatic control boxes 303. The inner top blocks 304 are supported and reset by the contraction and reset of multiple groups of connecting springs 313.

[0045] As Figures 4 to 5 shown, outer clamping plates 305 are slidably assembled on both sides of the inner top column 302. The outer walls of the pipe-type automotive parts sleeved outside the inner top column 302 are clamped and fixed by controlling the movement of a pair of outer clamping plates 305.

[0046] Specifically, a pair of limiting sliding grooves are provided above the clamping base plate 301. By providing the limiting sliding grooves, an assembly sliding space is provided for the threaded sliders 308.

[0047] As Figures 4 to 5 shown, a threaded slider 308 is slidably assembled in each of the pair of limiting sliding grooves, and the threaded slider 308 is fixedly assembled at the bottom of the outer clamping plate 305. The threaded slider 308 plays a role in assembling and fixing the outer clamping plate 305 and controlling its movement.

[0048] As Figures 4 to 5 shown, a threaded rotating shaft 309 is rotatably connected inside the clamping base plate 301, and the threaded rotating shaft 309 penetrates through the pair of threaded sliders 308. The threaded rotating shaft 309 plays a role in supporting and limiting the pair of threaded sliders 308 and controlling their movement.

[0049] It should be noted that external threads with opposite rotation directions are provided on both sides of the threaded rotating shaft 309. Internal threads with the same rotation direction are provided inside the pair of threaded sliders 308. So that the pair of threaded sliders 308 move in opposite directions as the threaded rotating shaft 309 rotates under the action of the internal and external threads, thereby facilitating the clamping of the pipe - type automotive parts sleeved outside the inner top column 302 by the movement of the pair of outer clamping plates 305.

[0050] As Figures 2 to 3 shown, one end of the threaded rotating shaft 309 located outside the limiting sliding groove is fixedly connected with a clamping control end 310. The threaded rotating shaft 309 is rotationally driven by controlling the rotation of the clamping control end 310.

[0051] As Figures 4 to 5 shown, an airbag ring 311 is fixedly connected to the side of the threaded slider 308 close to the inner top column 302, and the airbag ring 311 is sleeved outside the threaded rotating shaft 309. The airbag ring 311 plays a role in storing gas, and at the same time, it can play a role in dust - proof protection for the threaded rotating shaft 309.

[0052] As Figures 4 to 5 shown, a conduction air pipe 312 is connected between the airbag ring 311 and the pneumatic control box 303. The conduction air pipe 312 plays a role in connecting the airbag ring 311 and the pneumatic control box 303, facilitating the gas in the airbag ring 311 to be transported into the pneumatic control box 303 along the conduction air pipe 312, so as to facilitate the movement control of the inner top block 304.

[0053] During specific use, the tubular automotive parts to be detected can be sleeved outside the inner top column 302. The inner top column 302 is used to perform preliminary limit on the tubular automotive parts. Subsequently, by controlling the rotation of the clamping control end 310 to drive the rotation of the threaded rotating shaft 309, a pair of threaded sliders 308 move in opposite directions along with the rotation of the threaded rotating shaft 309 under the action of the internal and external threads. Thus, the outer walls of the tubular automotive parts are clamped and fixed by driving the movement of a pair of outer clamping plates 305 through a pair of threaded sliders 308.

[0054] Meanwhile, under the action of the movement of the threaded slider 308 along with the rotation of the threaded rotating shaft 309, the airbag ring 311 can be extruded, so that the gas in the airbag ring 311 is transported into the pneumatic control box 303 along the conduction air pipe 312. By transporting gas into the pneumatic control box 303, the inner top block 304 pops out under the action of gas pressure. Thus, the inner walls of the tubular automotive parts are resisted and limited by multiple groups of inner top blocks 304.

[0055] Subsequently, the tubular automotive parts that have been clamped and positioned can be detected. After the detection is completed, by manually rotating the control handwheel 207 to drive the rotation of the driving rotating shaft 206, the assembly rotating shaft 202 drives the bearing tray 203 to rotate synchronously under the meshing action of the driven bevel gear 204 and the driving bevel gear 205. By rotating the bearing tray 203, the tubular automotive parts at the next working station can be detected. Through the setting of multiple working stations, the effect of auxiliary clamping and positioning of the tubular automotive parts is improved.
