The working principle of the technical scheme is as follows: when the pipe 600 enters the inner wall spraying machine 300 for inner wall spraying and enters the outer wall spraying machine 400 for outer wall spraying, the requirement on the relative position of the pipe 600 is high, if the position of the pipe cannot be kept at the centering and level in the conveying process, the spray gun cannot uniformly spray paint everywhere, and the paint spraying effect of the pipe cannot be guaranteed. The pipe centering device 200 is used for adjusting the placing position of the pipe before the inner wall and the outer wall of the pipe are sprayed. After the pipe 600 is loaded to the pipe placing table 220, the plurality of pipe clamping assemblies 230 clamp and fix a plurality of positions of the pipe 600, and in the clamping process, the pipe clamping assemblies 230 clamp and fix the pipe 600 while centering the placing position of the pipe 600, so that the pipe 600 is prevented from being shifted to the position before being transferred to the conveying trolley 110.
The beneficial effects of the above technical scheme are that: this embodiment adopts a plurality of pipe fitting clamping assembly 230 to carry out position centering adjustment to pipe fitting 600 to ensure that the pipe fitting can the even spraying when carrying out inner wall, outer wall spraying, guarantee the spraying quality.
Referring to fig. 2, 3 and 4, in an embodiment of the present invention, the pipe clamping assembly 230 includes:
a fixing frame 232 located below the pipe placing table 220 and fixedly connected to the frame plate 231;

The working principle of the technical scheme is as follows: centering the tube 600 is achieved by simultaneously clamping the tube 600 by a plurality of in-line tube clamping assemblies 230. The gripping and unclamping action of the tubular 600 by the tubular gripper assembly 230 is accomplished by: the fixing frame 232 is fixed on the bottom frame 210 as a basic frame, the driving screw 233 is in threaded connection with the fixing frame 232, the driving screw 233 is driven by the motor 234 to slide up and down relative to the fixing frame 232 and simultaneously drive the linkage bridge 235 to slide up and down, and since the linkage bridge 235 is in fit connection with the guide groove 237 through the sliding bolt 238, the two arc-shaped clamping arms 236 move close to or away from each other simultaneously in the process of sliding the linkage bridge 235 up and down, so as to clamp or release the pipe 600. In the drawing, when the driving screw 233 moves upward together with the coupling bridge 235, since the interval between the two slide bolts 238 fixed to the coupling bridge 235 is kept constant, the relative positions of the slide bolts 238 in the guide grooves 237 are moved upward, by which the two arc-shaped gripping arms 236 approach each other to perform a gripping action on the pipe 600. As described above, the release of the tubular from the tubular gripping assembly 230 is the reverse of the gripping action.
The beneficial effects of the above technical scheme are that: the clamping and loosening actions of the pipe 600 are realized through the mechanical transmission of the driving screw 233, the position of the pipe 600 can be centered and adjusted, the pipe 600 can be firmly fixed in the middle position, the position is always kept unchanged before the pipe is transferred to the conveying trolley 110, and the phenomenon that the spraying effect is finally deteriorated due to the displacement of the pipe is avoided.

The working principle and the beneficial effects of the technical scheme are as follows: the centering of the pipe 600 is achieved by the pipe clamp assembly 230 being in a straight line, and particularly by the two arc clamp arms 236 being gradually closed together, the position of the pipe 600 is continuously adjusted in the closing process, and the centering is finally achieved, and the pipe 600 is clamped to keep the centering state without displacement. In order to further improve the centering and clamping effect of the arc-shaped clamping arms 236, the flat plate 239 is further arranged on the arc-shaped clamping arms 236, and the flat plate 239 is always contacted with the outer peripheral wall of the pipe fitting 600 to guide the pipe fitting during the clamping process of the arc-shaped clamping arms 236, so that the direction of the pipe fitting 600 is always consistent with the direction of the flat plate 239. After the length direction of the plate 239 is adjusted, the length direction of the pipe 600 can be kept in a centered state under the guiding action of the plate 239.

The working principle and the beneficial effects of the technical scheme are as follows: in the process of limiting and guiding the length direction of the pipe fitting 600 by the flat plate 239, the contact part of the flat plate 239 and the pipe fitting 600 cannot be effectively limited, so that an outer arc surface 2310 contacting the pipe fitting 600 is arranged on the flat plate 239, and two alignment flanges 2311 which are symmetrical in axis are arranged on the outer arc surface 2310. During the process of holding the pipe 600 by the arcuate holding arms 236, the pipe 600 contacts the groove 2312 formed between the alignment flanges 2311. Until a total of three plates 239 on the two arcuate gripper arms 236 on the bridge 235 contact the tubular member 600, the opposing sides of the alignment flanges 2311 of each arcuate surface 2310 and the 3 locations at the bottom of the grooves 2312 define a unique location for the plate 239 to contact the tubular member 600, and the unique location of the tubular member 600 is determined by the position definition of the three plates 239. The centering of the pipe 600 during the conveyance process can be ensured by the position-defining effect of the three flat plates 239.
