Description

Technical Field

[0001] The utility model belongs to the technical field of positioning tooling, and in particular relates to a ladder welding positioning tooling. Background Art

[0002] A ladder is a kind of staircase with a steep slope. People need to hold the ladder with both hands when going up and down, or it is a straight ladder made of iron chains or ropes. The main components of a ladder are vertical poles and horizontal bars, which are usually made of metal or alloy materials. It is mainly used in various engineering construction projects such as building construction, bridges, tunnels, water towers and dams. The vertical poles and horizontal bars of the ladder need to be positioned by positioning tooling when welding.

[0003] Based on the above, the inventors found that the existing ladder welding positioning tooling has the following shortcomings:

[0004] 1. The ladder welding positioning tool cannot be turned over, resulting in the inability to weld the bottom between the vertical pole and the horizontal pole. It is inconvenient to add a turning measure to the positioning tool to turn over and weld the bottom of the ladder after the upper part is welded;

[0005] 2. The vertical poles and horizontal bars of the ladder need to be fixed one by one, which makes the fixing process of the vertical poles and horizontal bars more complicated. It is not convenient to add clamping measures to the positioning tooling to push the vertical poles to clamp the horizontal bars to achieve the overall fixation of the ladder. Utility Model Content

[0006] In order to solve the above technical problems at least to a certain extent, the utility model provides a ladder welding positioning tool.

[0007] The purpose and effect of the ladder welding positioning tool of the utility model are achieved by the following specific technical means:

[0008] A ladder welding positioning tool comprises a tool body; the tool body is provided with a fixed bearing plate in the left and right directions, four corners of the fixed bearing plate are provided with through holes penetrating up and down, a vertical plate in the front and back directions is provided at the right end of the top end face of the fixed bearing plate, three pairs of semicircular head plates with front and back through holes arranged in front and back are provided in the middle of the top end face of the fixed bearing plate, a bearing flip plate in the front and back directions is installed on the semicircular head plate of the fixed bearing plate through a fixed axis, a bearing plate in the front and back directions is provided in the middle of the bearing flip plate, six threaded holes penetrating up and down arranged in front and back are provided on the bearing plate of the bearing flip plate, three vertical plates with left and right through holes arranged in front and back are provided on the top end face of the bearing plate of the bearing flip plate, three guide plates arranged in the front and back directions in the left and right directions are provided on the bearing plate of the bearing flip plate, and a flip cylinder in the front and back directions is provided on the left end of the guide plate of the bearing flip plate.

[0009] Furthermore, a limiting groove extending from front to back is provided on the upper portion of the inner end surface of the vertical rod clamping block.

[0010] Furthermore, the outer end of the threaded rod for clamping the rotating rod is threadedly mounted with a vertical rod clamping block, and a threaded hole penetrating left and right is provided at the bottom of the vertical rod clamping block.

[0011] Furthermore, the left and right end surfaces of the fixed column that clamps the rotating rod are both provided with threaded rods, and the outer end surface of the threaded rod that clamps the rotating rod is provided with a regular hexagonal prism.

[0012] Furthermore, a clamping rotating rod in the left and right directions is installed on the vertical plate that carries the flip plate through a bearing, and a fixed column is arranged in the middle of the clamping rotating rod.

[0013] Furthermore, a regular hexagonal groove is provided in the middle of the top end surface of the U-shaped plate of the cross bar positioning seat, and a spacer column in the upper and lower directions is provided on the bottom end surface of the U-shaped plate of the cross bar positioning seat, and a threaded column is provided on the bottom end surface of the spacer column of the cross bar positioning seat.

[0014] Furthermore, a crossbar positioning seat is installed at the top of the threaded hole supporting the flip plate in the up-and-down direction, and a U-shaped plate with an opening in the left-and-right direction and facing upward is arranged at the top of the crossbar positioning seat.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The convenient load-bearing flip plate is installed on the fixed load-bearing plate through a fixed axis for flipping. The convenient load-bearing flip plate is flipped 180 degrees so that the bottom of the ladder with the upper welded is welded upwards, which solves the problem that the ladder welding positioning tooling cannot be flipped, resulting in the inability to weld the bottom between the vertical pole and the horizontal pole, and it is inconvenient to add flipping measures to the positioning tooling to flip and weld the bottom of the ladder with the upper welded.

[0017] The convenient clamping rotating rod is installed on the load-bearing flip plate through a bearing to carry the upright clamping block, and the upright clamping block is used to push the upright clamping cross bar to realize the overall fixation of the ladder. This solves the problem that the uprights and cross bars of the ladder need to be fixed one by one, resulting in a cumbersome fixing process of the uprights and cross bars, and it is inconvenient to add clamping measures to the positioning tooling to push the upright clamping cross bar to realize the overall fixation of the ladder.
