Description

Technical Field

[0001] The utility model belongs to the technical field of welding, and in particular relates to a horizontal H-shaped steel welding table. Background Art

[0002] H-shaped steel is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". When using a welding process that is lower in production cost and higher in production efficiency than the hot rolling process to manufacture H-shaped steel, the cut flange plate and web plate need to be spliced ​​in place and welded. However, when welding H-shaped steel structural parts, the flange plate is prone to offset, resulting in overall dimensional deviation.

[0003] A Chinese patent document with authorization announcement number CN219465243U discloses a horizontal H-beam welding table, which, after a web is supported by a height-adjustable lifting platform, clamps and limits the flange plates on both sides of the web through rotatable and laterally movable rollers in conjunction with a top cylinder and an auxiliary cylinder, thereby aligning the web and flange plates and completing the splicing work before welding.

[0004] However, in the prior art, although the welding table can clamp the limited flange plate in multiple directions, it is difficult to conveniently correct the position of the flange plate when the flange plate is skewed during the process of moving toward the web plate. Therefore, a horizontal H-beam welding table is proposed. Utility Model Content

[0005] The utility model aims to provide a horizontal H-shaped steel welding platform.

[0008] The clamping assembly comprises a longitudinal moving part which can adjust the placement position of the flange plate according to the width of the web plate, an adjusting part which can adjust the inclination of the flange plate, and a limiting part which can limit the movement of the clamped flange plate.

[0009] Preferably, the longitudinal moving member comprises guide rails fixedly installed in the supporting assembly, and the guide rails are movably connected with the longitudinal moving frame.

[0010] Preferably: the adjusting member includes a second hydraulic rod fixedly installed in the longitudinal moving frame, the telescopic end of the second hydraulic rod is movably connected to a bending frame, the bending frames are movably connected to a clamping frame, a third hydraulic rod is arranged between the supporting assembly and the bending frame, and a fourth hydraulic rod is arranged between the bending frame and the clamping frame.

[0011] Preferably: the limiting member comprises a clamping roller movably installed in the longitudinal shift frame and the clamping frame, and the outer side surface of the clamping roller is fixedly connected to the limiting sleeve.

[0012] Preferably, the guide rail is slidably connected to the longitudinal moving frame.

[0013] Preferably: the second hydraulic rod, the clamping frame, the third hydraulic rod and the fourth hydraulic rod are all rotatably connected to the bending frame, and the clamping frame is rotatably connected to the fourth hydraulic rod.

[0014] Preferably, the outer diameter of the limiting sleeve gradually decreases from both ends to the middle.

[0015] The beneficial effect of the utility model is that after the longitudinal position of the clamping assembly is preliminarily determined according to the size data of the web plate and the flange plate, the inclination of the flange plate clamped between the limit sleeves of different heights can be conveniently adjusted through the operation of the driving assembly, the third hydraulic rod and the fourth hydraulic rod, so that the web plate and the flange plate are fully aligned.

[0029] In this embodiment: the clamping assembly 2 includes a longitudinal moving member that can adjust the placement position of the flange plate according to the width of the web plate, an adjusting member that can adjust the inclination of the flange plate, and a limiting member that can limit the movement of the flange plate after being clamped.
