Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] In one embodiment, refer to Figures 1 to 8 A welding training platform includes an operating table 1. Two mounting seats 4 are movably mounted on the top of the operating table 1. A rotating shaft 6 is movably mounted on one side of each mounting seat 4 facing each other. A drive component 5 for rotating the rotating shaft 6 is mounted on the side of each mounting seat 4. A workpiece placement mechanism 12 is provided on the rotating shaft 6 for placing the workpiece to be welded. A drive component 15 for rotating the mounting seats 4 is provided at the bottom of the operating table 1. An arc-shaped protective cover 7 is movably mounted on one side of the top of the operating table 1. An observation port is provided on the side of the protective cover 7, and a transparent protective plate 10 is provided at the observation port. An arm placement groove 22 for placing the operator's arm is provided on the side of the protective cover 7 near the rotating shaft 6 for extracting welding fumes. A weld inspection mechanism 3 is provided on the top of the operating table 1 for inspecting the flatness of the weld joint of the two workpieces before and after welding.

[0029] In use, the mounting base 4 can be rotated by the second drive component 15, causing the end of the rotating shaft 6 away from the mounting base 4 to rotate away from the protective cover 7. The workpiece is placed on the workpiece placement mechanism 12 on the circumference of the rotating shaft 6. The second drive component 15 drives the mounting base 4 to reset. The positions of the two workpieces on the rotating shaft 6 are adjusted by the workpiece placement mechanism 12 until the weld joints of the two workpieces are aligned. After the weld inspection mechanism 3 performs a flatness inspection on the weld joint, the operator can stand on the side of the protective cover 7 away from the rotating shaft 6, place both arms in the arm placement slots 22, and perform welding operations. The weld joint can be observed through the transparent protective plate 10. The operation is highly safe, and there is no need to wear or hold a protective mask during the welding process. In addition, the fume extraction mechanism 9 extracts the fumes generated during welding to prevent the fumes from spreading into the air and being inhaled by the operator. During the welding process, the rotating shaft 6 and the workpiece can be rotated by the first drive component 5, which facilitates welding operations and makes the operation flexible.

[0030] In a preferred embodiment of the present invention, the weld inspection mechanism 3 includes a telescopic component 31 installed on the top of the operating table 1. A lifting seat 32 is installed at one end of the piston rod of the telescopic component 31. The top of the lifting seat 32 has an installation hole, and a rubber sleeve 36 is provided inside the installation hole. An extension rod 33 is inserted through the rubber sleeve 36. A laser emitter 34 and a laser receiver 35 are respectively installed on the inner walls of both sides of the lifting seat 32. When no external force is applied to the extension rod 33, the resistance of the rubber sleeve 36 to the extension rod 33 is offset by the weight of the extension rod 33 itself.

[0031] In a preferred embodiment of the present invention, the telescopic component 31 is an electric telescopic rod, a hydraulic cylinder, etc. In this embodiment, the preferred telescopic component 31 is an electric telescopic rod.

[0032] In a preferred embodiment of the present invention, a leveling seat 2 is installed on the top of the operating table 1. The top of the leveling seat 2 is flat, and the top position of the leveling seat 2 corresponds to the bottom position of the extension rod 33. An indicator light is provided on the side of the lifting seat 32. The position of the lifting seat 32 can be adjusted by the telescopic component 31, so that the bottom of the extension rod 33 abuts against the top of the leveling seat 2, and the bottom of the extension rod 33 is at the same horizontal position. At this time, the bottom of the extension rod 33 is located on top of the laser emitter 34 and the laser receiver 35. The laser receiver 35 can receive the laser emitted by the laser emitter 34. After the welding ends of the workpiece are joined and after welding is completed, the telescopic component 31 drives the lifting seat 32 to move upward, so that the top of the extension rod 33 moves to the side of the workpiece. When the workpiece and the drive shaft 6 rotate one revolution, and the workpiece joint and weld are flat, the extension rod 33 will not move up or down relative to the lifting seat 32, and the laser receiver 35 can receive the laser emitted by the laser emitter 34. The indicator light will not light up, indicating that the joint is good and the welding quality is high. When the workpiece joint and weld are not flat, the extension rod 33 is pushed downward and moves downward relative to the lifting seat 32. At this time, the bottom of the extension rod 33 is between the laser emitter 34 and the laser receiver 35. The laser receiver 35 cannot receive the laser emitted by the laser emitter 34, and the indicator light will light up, indicating that the joint effect is poor or the welding quality is low. The flatness of the weld is checked before and after welding to avoid uneven welds caused by poor joint effect and to ensure the accuracy of welding quality detection.

One end of the piston rod of the telescopic component 20 is connected to the side of the movable rod 21. When the workpiece is sleeved on the outside of the movable sleeve 124, the position of the support component 121 is adjusted by pushing the telescopic component 122. The support component 121 supports and positions the inner wall of the workpiece. Then, the position of the movable rod 21 and the movable sleeve 124 is adjusted by pushing the telescopic component 20, so that the welding ends of the two workpieces can be connected.

[0034] In a preferred embodiment of the present invention, a laser receiver 2 19 and a laser emitter 2 13 are respectively installed at the ends of the two rotating shafts 6 that are close to each other. When the driving component 2 15 drives the mounting base 4 to rotate, the laser receiver 2 19 can receive the laser emitted by the laser emitter 2 13 to determine whether the two rotating shafts 6 are coaxially set, so as to ensure that the two rotating shafts 6 can rotate coaxially.

[0035] In a preferred embodiment of the present invention, guide grooves 23 are provided on the bottom inner wall and the top inner wall of the arm placement groove 22. A protective curtain 14 is slidably installed inside the guide groove 23.
