To achieve the goals above, the utility model relates to a kind of for welding the main structure packet to jaws equipment of round tube Include: U-shaped gripper clamp and the angle bar being set in jaw, the front end of U-shaped gripper clamp be provided with U-shaped structure upper clamping end and lower folder End is held, wherein the U-shaped arm of upper clamping end is straight-arm structure, the front end of the U-shaped arm of lower clamping end is bending structure, in upper clamping end The angle bar to support and be aligned round tube is provided between lower clamping end, wherein the opening upwards of angle bar, and angle bar is curved The front end bending place of the U-shaped arm of lower clamping end is stuck at folding, when welding round tube, round tube is placed on the upper side of angle bar, upper folder It holds end and is stuck in round tube upper side to be fixed, the square hole that Open Side Down, square hole setting are provided on the leading flank of angle bar Position it is corresponding with the front end bending place of lower clamping end, square hole is covered in the front end of the U-shaped arm of lower clamping end, to play connection Effect, and can carry out replacing various sizes of angle bar as needed.

Further, it is provided on the front end downside of the U-shaped arm of the upper clamping end of the utility model and is pressed from both sides to fixation The arc groove for the round tube shape structure held.

Further, the U-shaped arm bending angle of the lower clamping end of the utility model is 80 ° -120 °, and optimal angle is 90 °, The bending angle of angle bar is identical as the bending angle of U-shaped arm of lower clamping end.

When the utility model is used, first cover angle bar on square hole, it is then that two sections of diameters to be welded are identical Round tube is placed in angle bar, and weld seam is placed between two U-shaped arm of U-shaped arm of upper clamping end, after adjusting two round tubes to suitable spacing, leads to It crosses operation U-shaped gripper clamp and two round tubes is clamped and then welded, upper clamping end and lower clamping end, replacement are unclamped after welding Next group of round tube to be welded.

Compared with prior art, acquirement has the beneficial effect that the utility model:

It can make firmly to clamp round tube in the case where nozzle docks accurate situation by the cooperation of U-shaped gripper clamp and angle bar, Convenient for improving the accuracy of welding, while convenient for adjusting the spacing of two round tubes, using the company of square hole and lower clamping end sleeve type Binding structure can be easy to disassemble and replaces angle bar, while having stronger adaptability to different pipe outside diameters, passes through upper clamping end The design of arc groove can guarantee the fastness of clamping, while can satisfy the clamping needs of different-diameter round tube, grasp simultaneously To make simply, round tube docking time is short, and docking accuracy is high, welding efficiency is effectively raised,

Its main structure is simple, and design concept is ingenious, easy to install and use, and stability is good, intensity is high, application environment Close friend, wide market.
