[0038] In this embodiment, when it is necessary to inspect the quality of the weld seam of the welded part 2, the controller 102 is first connected to the external power supply using the prepared wire, and then the controller 102 is turned on, and images showing that the weld seam on the outer surface of the welded part 2 and the weld seam on the inner surface of the welded part 2 are both qualified are stored in the storage module of the controller 102. Then, the welded part 2 to be inspected is placed inside the T-slot 103, and then the controller 102 and the auxiliary mechanism 3 are used to position and fix the welded part 2 at a suitable position inside the T-slot 103. Then, the controller 102 is used to simultaneously start the two electric push rods 113. At this time, the two started electric push rods 113 will cooperate with the corresponding U-shaped frame 110 and the corresponding set of slide grooves 111.

The controller 102 compares the received outer surface weld seam image of the welded part 2 and the inner surface image of the welded part 2 with the pre-stored outer surface weld seam image of the welded part 2 and the inner surface image of the welded part 2 respectively. When the image received by the controller 102 is the same as the pre-stored image, it can be said that the weld seam quality of this welded part 2 is qualified. When the image received by the controller 102 is different from the pre-stored image, it can be said that the weld seam quality of this welded part 2 is unqualified. When the two industrial cameras 115 are rotated 360 degrees, the servo motor 105 and the two industrial cameras 115 are directly turned off by the controller 102. Then, the two electric push rods 113 are started by the controller 102 until the two industrial cameras 115 are reset to their original positions. Then the welded part 2 that has completed the inspection can be removed.

[0039] The effect and working principle of the entire mechanism are as follows:

[0040] During the inspection phase, when it is necessary to inspect the quality of the weld seam of the welded part 2, the controller 102 is first connected to the external power supply using the prepared wires, and then the controller 102 is turned on, and images showing that the weld seam on the outer surface of the welded part 2 and the weld seam on the inner surface of the welded part 2 are both qualified are stored in the storage module of the controller 102. The welded part 2 to be inspected is then placed inside the T-slot 103, and then the controller 102 and the auxiliary mechanism 3 are used to position and fix the welded part 2 at a suitable position inside the T-slot 103. The controller 102 is then used to simultaneously start the two electric push rods 113, and at this time, the two started electric push rods 113 will both be in cooperation with the corresponding U-shaped frame 110 and a corresponding set of slide grooves 111. , driving the corresponding slide 112 to move vertically downward, and at the same time, the two slides 112 that move vertically downward will drive the corresponding industrial cameras 115 to move vertically downward with the cooperation of the corresponding perforated blocks 114. When the two industrial cameras 115 are moved to the point where they can no longer move, one of the industrial cameras 115 is outside the weldment 2, and the other industrial camera 115 is in the middle of the weldment 2. Then, the controller 102 is used to close the two electric push rods 113. At this time, the two closed electric push rods 113 will both stop moving vertically downward with the cooperation of the corresponding U-shaped frame 110, the corresponding set of slide grooves 111, the corresponding slide 112 and the corresponding perforated block 114 (as shown in FIG. Figure 4As shown), the controller 102 is then used to simultaneously start the two industrial cameras 115, and then the servo motor 105 is started by the controller 102. At this time, the started servo motor 105 will drive the circular plate 107 to rotate with the cooperation of the bracket 104 and the connecting rod 106, and the rotating circular plate 107 will drive the four T-shaped blocks 109 to rotate with the cooperation of the annular groove 108. At the same time, the rotating circular plate 107 will drive the two U-shaped frames 110 and the counterweight block 116 to rotate, and the two rotating U-shaped frames 110 will drive the corresponding slides 112 to rotate with the cooperation of the corresponding set of slide grooves 111 and the corresponding electric push rods 113. At the same time, the two rotating slides 112 will drive the corresponding industrial cameras 115 to rotate with the cooperation of the corresponding perforated blocks 114. When the two started industrial cameras 115 are rotating, the two started and rotating industrial cameras 115 will be respectively The outer surface weld seam of the welded part 2 and the inner surface weld seam of the welded part 2 are photographed, and the photographed images are transmitted to the controller 102 in the form of electrical signals. The controller 102 compares the received outer surface weld seam image of the welded part 2 and the inner surface image of the welded part 2 with the pre-stored outer surface weld seam image of the welded part 2 and the inner surface image of the welded part 2 respectively. When the image received by the controller 102 is the same as the pre-stored image, it can be said that the weld seam quality of this welded part 2 is qualified. When the image received by the controller 102 is different from the pre-stored image, it can be said that the weld seam quality of this welded part 2 is unqualified. When the two industrial cameras 115 are rotated 360 degrees, the servo motor 105 and the two industrial cameras 115 are directly turned off by the controller 102. Then, the two electric push rods 113 are started by the controller 102 until the two industrial cameras 115 are reset to their original positions. Then, the welded part 2 that has completed the inspection can be removed.

[0041] In the positioning and fixing stage, when the welding part 2 needs to be positioned and fixed, the welding part 2 is first placed inside the T-slot 103, and then the driving motor 301 is started by the controller 102. At this time, the started driving motor 301 will drive the auxiliary rod 303 to rotate with the cooperation of the auxiliary hole 302, and the rotating auxiliary rod 303 will drive the first bevel gear 304 to rotate. At the same time, the rotating first bevel gear 304 will drive the three single-head threaded rods 307 to rotate with the cooperation of the three second bevel gears 308, the auxiliary frame 305 and the three cylindrical holes 306. The three rotating single-head threaded rods 307 will all drive the corresponding auxiliary blocks 311 to move with the cooperation of the corresponding fixing frames 309 and the corresponding round rods 310. At the same time, the three moving auxiliary blocks 311 will all drive the corresponding rubber pads 312 Move. When the three auxiliary blocks 311 are moved to the point where they can no longer move, the controller 102 is first used to turn off the drive motor 301. At this time, the turned-off drive motor 301 will cause each auxiliary block 311 to stop moving. At the same time, the surface of each stopped rubber pad 312 will be against the inner surface of the weldment 2, and the top center of the weldment 2 is just in the same straight line with the top center of the T-slot 103, which means that the positioning and fixing operation of the weldment 2 is completed. When the weldment 2 needs to be removed, the controller 102 is first used to start the drive motor 301. At this time, the started drive motor 301 will, with the cooperation of the above-mentioned components, cause the three auxiliary blocks 311 and the three rubber pads 312 to reset and move. When the three auxiliary blocks 311 are reset to their original positions, the controller 102 is directly used to turn off the drive motor 301, and then the weldment 2 can be directly removed.
