Description

Technical Field

[0001] The utility model relates to a workpiece clamping device, in particular to a full-automatic welder training and assessment workbench, belonging to the technical field of welding training and assessment. Background Art

[0002] Welder training and assessment cannot do without a welding workbench. With the development of welding technology, the existing welding methods have developed from traditional manual welding to full-automatic welding. At the same time, the pipe diameters of welded pipes have developed from ordinary pipe diameters to large pipe diameters and extra-large pipe diameters. Currently, the pipes used for full-automatic welder training and assessment are generally pipes with a diameter of more than 600 mm. However, traditional welding workbenches have problems such as difficult clamping, difficult movement, and difficult displacement of pipes during the full-automatic welding process of large-diameter pipes. At the same time, due to the heavy weight of large-diameter pipes themselves, and the fact that the machine needs to be sleeved on the pipes during the full-automatic welding process, the load on the workbench is further increased. Therefore, using a traditional welding workbench for full-automatic welding of large-diameter pipes has safety hazards such as inclination, collapse, and fracture. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a full-automatic welder training and assessment workbench that meets the full-automatic welding needs of large-diameter and extra-large-diameter metal pipes with different lengths, different diameters, different thicknesses, and different positions, and ensures the stability and safety of construction.

[0004] The technical solution adopted by the utility model to solve the technical problem is as follows:

[0005] A full-automatic welder training and assessment workbench includes a front portal steel frame, a rear portal steel frame, and a hoist. A right-angle steel plate is arranged at the top of the front portal steel frame. The bottom of the right end of the right-angle steel plate is provided with a rear portal steel frame. A lifting steel pipe is slidably connected below the rear portal steel frame. A hoist is arranged between the lifting steel pipe and the rear portal steel frame. A rotating shaft rod is rotatably connected between the inner walls of the front portal steel frame. Two positioning sleeves are arranged on the rotating shaft rod. A support steel pipe is inserted into the positioning sleeve and fixed by a third tightening bolt. The upper end of the support steel pipe is located on the lifting steel pipe. A pipe fixing clamp is arranged on the support steel pipe.

[0006] The pipe fixing clamp is distributed in an L shape and is arranged on the support steel pipe behind the positioning sleeve. A second tightening bolt is arranged at the top of the pipe fixing clamp.

[0007] Lifting sleeves are respectively arranged at both ends of the lifting steel pipe. The lifting sleeves are sleeved on the support rods at both ends of the rear portal steel frame, and a first tightening bolt is arranged outside the lifting sleeves.

[0008] Below the top of the said back door-shaped steel frame, there is an upper lifting lug. In the middle of the lifting steel pipe, there is a lower lifting lug, and the positions of the upper and lower lifting lugs correspond to each other vertically. The top of the hoist is connected to the upper lifting lug through a hook, and the hook on the hoist chain is connected to the lower lifting lug.
