Description

Technical Field

[0001] The utility model relates to the technical field of pipeline welding auxiliary equipment, in particular to a pipeline welding workpiece. Background Art

[0002] Pipeline welding refers to the process of melting and fusing the ends of two pipes together by high temperature or high pressure to achieve pipeline connection. It is a very important part of pipeline engineering, and its quality directly affects the service life and safety of the pipeline. When welding two sections of pipeline, the two sections of pipeline need to be fixed by clamps respectively, and the welding surfaces of the two sections of pipeline are butt-jointed, so as to weld the two sections of pipeline using welding equipment;

[0003] For example, a pipe welding clamp disclosed in publication number CN209986475U prevents the pipe from moving during welding by cooperating with a fixing block and a pressing block, thereby ensuring the welding quality. The bracket can be opened and closed by the lock and hinge structure of the bracket, thereby facilitating the insertion and removal of the pipe. However, in this application, after the two sections of the pipe are fixed between a corresponding set of fixing blocks and pressing blocks, the two sections of the pipe cannot be further adjusted for horizontal movement, thereby making it impossible to conveniently weld the welding surfaces of the two sections of the pipe. In addition, due to the deviation in the clamping and fixing of the pipe, the butt joint heights of the pipes at both ends may be inconsistent. Therefore, this application also cannot separately adjust the fixing heights of the two sections of the pipe, which makes it easy for the pipe welding to be misaligned. Utility Model Content

[0022] like Figure 2-Figure 4As shown, a fixing stud 26 is fixedly installed at the center position of the upper end of the slide 6, and connecting screws 23 are respectively inserted and installed at both ends of the mounting seat 7. The lower end of the connecting screw 23 passes through the supporting plate 8 and is threadedly connected to the corresponding screw groove on the slide 6, and the connecting screw 23 located between the mounting seat 7 and the end of the connecting screw 23 is also sleeved with a compression spring A24, and the mounting seat 7 is movably mounted on the supporting plate 8 through the connecting screw 23, and the vertical height adjustment of the mounting seat 7 can be achieved with the help of the force of the compression spring A24. A mounting hole 14 is opened at the center position of the supporting plate 8, and a plurality of latch teeth 15 are also fixedly installed at the lower end of the supporting plate 8 located at the peripheral position of the mounting hole 14, and the plurality of latch teeth 15 are annularly arranged at the lower end of the supporting plate 8 at the peripheral position of the mounting hole 14;

[0023] like Figure 3-Figure 5 As shown, a mounting groove 16 is provided at the center position of the adjusting wheel 9, a limiting ring 17 is fixedly installed inside the mounting groove 16, and the transverse cross-section of the limiting ring 17 is a regular hexagon.

[0024] It should be noted that the utility model is a welding workpiece for pipelines. When welding two sections of pipelines, one end of the two sections of pipelines can be respectively inserted and installed on the corresponding two mounting seats 7. Then, by rotating the adjusting screw 13, the lower end of the adjusting screw 13 rotates on the upper end of the pressure block 12 and drives the pressure block 12 to move downward, so that one end of the pipeline can be clamped and fixed in the V-shaped groove on the opposite side of the pressure block 12 and the mounting seat 7.

Then, if there is a height difference problem on the welding surfaces of the two sections of pipelines, the adjusting wheel 9 can be pressed down with one finger, so that the adjusting wheel 9 passes through the outer rotating groove 19 in the mounting seat. The mounting hole 14 moves downward. At the same time, the adjusting wheel 9 also drives the limiting ring 17 to move downward in the limiting groove 22, and compresses the compression spring B25 toward the supporting plate 8 through the adjusting wheel 9. As a result, the tooth groove 20 is disengaged from the latch tooth 15 at the lower end of the supporting plate 8, and the adjusting wheel 9 can be rotated, so that the adjusting wheel 9 drives the connecting block 18 to rotate through the limiting ring 17. As a result, the screw hole 21 in the connecting block 18 is screwed up or down on the fixing stud 26, and the height of the supporting plate 8 can be adjusted in the reverse direction with the help of the adjusting wheel 9, so that the supporting plate 8 cooperates with the four connecting screws 23 and the compression spring A24 to move up and down stably, thereby adjusting the height of the mounting seat 7, that is, the height of the pipeline can be adjusted. Subsequently, the welding surfaces of the two sections of the pipeline can be welded by welding equipment, and the pipeline can be driven to rotate with the help of the balls in the V-grooves on the opposite sides of the mounting seat 7 and the pressing block 12, which is beneficial to the welding of the pipeline.
