After the position of the pushing platen 16 is moved, an operator can integrally rotate the air storage pipe 5 outside, the air storage pipe 5 rotates to drive the pushing disc 35, the pushing rod 18 and the limiting convex disc 37 to integrally rotate until the limiting convex disc 37 rotates to be matched with the limiting convex groove 38 in the pushing platen 16, at this moment, the pushing rod 18 continuously moves inwards to drive the limiting convex disc 37 to move inwards to enter the limiting convex groove 38, the limiting spring 22 and the air compressing disc 20 in the built-in cavity 19 can be extruded, the air in the built-in cavity 19 can be extruded when the air compressing disc 20 receives extrusion, the air in the built-in cavity 19 enters the extrusion rubber ring through the air supplementing pipe, at this moment, the air in the extrusion rubber ring is expanded to extrude the inner wall of the copper pipe 1, so that the friction force between the pushing platen 16 and the inner wall of the copper pipe 1 is increased, and finally the friction resistance is larger than the moving thrust of the pushing platen 16, at this moment, the pushing platen 16 can not move when the air compressing disc 20 is continuously inflated, and the inside of the copper pipe 1 can be sealed.
The air tightness of the welded joint 3 is detected, namely, when the pushing pressure plate 16 moves, the outer sleeve ring 4 is driven to synchronously move on the welded copper pipe 1 under the cooperation of the driven mechanism, and when the outer sleeve ring 4 moves outside the welded copper pipe 1, the smearing wheel 23 can roll on the welded joint 3 on the welded copper pipe 1, and foam water can be smeared outside the welded joint 3 uniformly while rolling, so that the welded joint 3 can be subjected to foam blocking, and the preparation work before the air tightness detection is completed;
The detection camera 25 can move along with the movement of the outer sleeve 4 and the smearing box 12, can shoot and observe the welding joint 3 while moving, and can display the observation result on the control panel 7 in real time, so that the surface integrity of the welding joint 3 can be observed.
When the internal plugging of the welded copper pipe 1 is finished, the pushing pressure plate 16 cannot move at the moment, after foam water on the external welding joint 3 is coated, the gas storage pipe 5 is continuously inflated at the moment, when the gas in the gas storage pipe 5 is increased but the pushing pressure plate 35 cannot be pushed to move at the moment, air in the gas storage pipe 5 enters the gas charging pipe 32, the piston plate 34 on the elastic frame 33 is pushed away, the gas charging pipe 32 is communicated, and at the moment, the air in the gas storage pipe 5 enters the welded copper pipe 1 through the gas charging pipe 32 and is accumulated in the welded copper pipe 1;
Because the inside of the welding copper pipe 1 is plugged, the air added in the welding copper pipe cannot be flushed out from the end part of the welding copper pipe 1, but can only be flushed out through the welding seam 3, at the moment, an operator can observe the foam water on the welding seam 3 on the welding copper pipe 1 outside, if the foam water does not generate foam, the air tightness of the welding seam 3 is good, no seam exists on the welding seam 3, if the foam water generates foam, the air tightness of the welding seam 3 is poor, the seam exists on the welding seam 3, at the moment, the position where the foam exists can be recorded, the later repair is convenient, and the air tightness detection work of the welding seam 3 on the welding copper pipe 1 can be completed.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
