Auxiliary tooling for welding steel structures

Abstract

An auxiliary tooling for steel structure welding includes a welding platform with several fixed sliders slidably mounted on it. A rotating arm is hinged to each slider, and a sliding chamber is mounted on the rotating arm. Limiting rods are symmetrically arranged within the sliding chambers, and the distance between two limiting rods can be adjusted by sliding. Clamping plates are arranged on the limiting rods. The limiting rods of this invention can slide to any position on the welding platform with the sliders and can reciprocate to achieve engagement or disengagement with the steel structural components. When a limiting rod is engaged with a steel structural component, the transverse partition to be welded can be directly inserted between adjacent limiting rods, thereby achieving rapid welding positioning. This design avoids the tedious operation of repeated marking and eliminates the need for manual fixing, significantly improving welding efficiency.

Description

Technical Field

[0001] This utility model belongs to the field of welding technology, specifically referring to an auxiliary tooling for welding steel structures. Background Technology

[0002] Steel structures are building structures made primarily of steel and are one of the main structural types in modern architecture. Their main body consists of steel beams, columns, trusses, and other components made from shaped steel sections and plates. To maintain the stability of the structural cross-sectional shape and enhance lateral stiffness, diaphragms are typically installed between the beams. These diaphragms are usually connected to the main structural components, such as the steel beams, using welding techniques.

[0003] In traditional welding operations, workers need to first mark and position the welded parts, then position them manually or with the aid of clamps, and finally perform the overlay welding after spot welding. This process has significant drawbacks: marking and positioning must be repeated for each steel structural component being welded, which is not only cumbersome but also inefficient. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides an auxiliary tooling for steel structure welding, which at least partially solves the above problems.

[0005] The technical solution adopted by this utility model is as follows: An auxiliary tooling for steel structure welding proposed in this utility model embodiment includes: Welding platform, used for leveling and positioning steel structural components to be welded; Several sliders are slidably disposed on the welding platform and can be fixed at the position to be welded; The first end of the rotating arm is hinged to the slider. A sliding chamber is located at the second end of the rotating arm; The limiting rods are symmetrically arranged in the sliding chamber, and the distance between the two limiting rods can be adjusted by sliding. Multiple clamping plates are arranged on the limiting rod to clamp and position the transverse partition to be welded.

[0006] Furthermore, the slider is provided with a first slot, the rotating arm is provided with a second slot, and a stop bar is slidably provided on the first slot, the stop bar being adapted to the second slot.

[0007] Furthermore, the upper edge of the welding platform is provided with a slide rail, and a locking groove is provided below the slide rail, with the slider slidably disposed in the slide rail.

[0008] Furthermore, the side wall of the slider is provided with a locking flange, and a bolt is provided through the locking flange. The end of the bolt is threadedly connected to a locking block, and the locking block is slidably disposed in the locking groove. The thickness of the locking block is less than the width of the locking groove.

[0009] Furthermore, the minimum distance between the bottom wall of the sliding chamber and the welding point is greater than the maximum height of the component to be welded, and the vertical distance between the bottom of the clamping plate and the welding point is positive when the clamping plate is in the clamping working state.

[0010] The beneficial effects of this utility model are as follows: the limiting rod can slide with the slider to any position on the welding platform for positioning, and can also reciprocate to achieve engagement or disengagement with the steel structure; when the limiting rod is embedded in the steel structure, the cross diaphragm to be welded can be directly inserted between adjacent limiting rods, thereby achieving rapid welding positioning; this design avoids the tedious operation of repeated scribing and eliminates the step of manual fixing, significantly improving welding efficiency.

[0016] like Figures 1-3 As shown in the figure, an auxiliary tooling for steel structure welding proposed in this embodiment of the present invention includes a welding platform 1, which supports the steel structural component 4 to be welded. Before welding, the steel structural component 4 needs to be leveled and positioned on the welding platform 1. Leveling means maintaining the parallelism of the steel structural component 4 to be welded, which is adjusted by a lifting column on the welding platform 1 (existing technology, not shown in the figure). Positioning means positioning the distance of the steel structural component 4 to be welded on the horizontal plane, so as to locate the welding point during subsequent welding operations. Several sliders 5 are slidably provided on the welding platform 1. After being moved to the welding positioning point, it can be fixed on the welding platform 1; a rotating arm 6 is hinged on the slider 5, and a sliding chamber 12 is provided at the end of the rotating arm 6 away from the slider 5. A symmetrically arranged limiting rod 9 is slidably arranged in the sliding chamber 12. The distance between the two limiting rods 9 can be adjusted so that the distance between the two limiting rods 9 is adapted to the thickness of the transverse partition to be welded; multiple clamping plates 13 are arranged on the limiting rods 9. The clamping plates 13 are located on both sides of the structural part to be welded. The clamping plates 13 can clamp and position the transverse partition to be welded, so as to fix it so that it can be spot welded before the welding operation.

[0017] In some embodiments, as needed, to keep the rotating arm 6 fixed in either a horizontal or vertical state, a first slot is provided on the slider 5, and a second slot is provided on the rotating arm 6. When the second slot rotates with the rotating arm 6 to a horizontal position, it coincides with the first slot. A stop bar 8 is slidably provided within the first slot, and the size of the stop bar 8 is also adapted to the second slot. Figure 1 As shown, when it is necessary to place the rotating arm 6 horizontally, the stop lever 8 can be pulled out, the rotating arm 6 can be rotated to a horizontal angle, and then the stop lever 8 can be inserted into the first slot and the second slot. At this time, the rotating arm 6 can no longer rotate. Figure 2 As shown, when the rotating arm 6 is kept vertical when needed, the stop bar 8 is pulled out, the rotating arm 6 is rotated to 90 degrees, and then the stop bar 8 is inserted into the first slot. When the rotating arm 6 is in a horizontal state, it is convenient to place the steel structure part 4 to be welded on the welding platform 1, avoiding interference between the steel structure part 4 to be welded and the rotating arm 6 and the limiting rod 9. After the steel structure part 4 to be welded is positioned, the rotating arm 6 is rotated to 90 degrees, and the positions of the limiting rod 9 and the clamping plate 13 are adjusted so that the transverse partition to be welded can be inserted between the clamping plates 13, thereby completing the welding positioning.

[0018] In some embodiments, the upper edge of the welding platform 1 is provided with a slide rail 2, and a locking groove 3 is provided below the slide rail 2. The slider 5 is slidably disposed in the slide rail 2. The side wall of the slider 5 is provided with a locking flange 7, and a bolt 10 is provided through the locking flange 7. The end of the bolt 10 is threadedly connected to a locking block 11. The locking block 11 is slidably disposed in the locking groove 3. The thickness of the locking block 11 is less than the width of the locking groove 3. When fixing the slider 5, simply rotate the bolt 10, and the locking block 11 threadedly connected to the bolt 10 will move towards the locking flange 7 until the locking block 11 is tightly fitted against the side wall of the locking groove 3. There is pressure between the locking block 11 and the locking groove 3. This pressure will increase the friction of the locking block 11. The locking block 11 will not slide under the action of friction, so the slider 5 is fixed and the rotating arm 6 on the slider 5 will also remain fixed.

[0019] In some embodiments, the minimum distance between the bottom wall of the sliding chamber 12 and the welding point is greater than the maximum height of the part to be welded (i.e., the transverse partition). When the rotating arm 6 is rotated to the vertical state, the distance between the sliding chamber 12 and the welding point is the minimum. That is, at this time, the bottom wall of the sliding chamber 12 is higher than the transverse partition. When the clamping plate 13 is in the clamping working state, the vertical distance between its bottom and the welding point is a positive value. That is, when the distance between the sliding chamber 12 and the welding point is the minimum, the bottom of the clamping plate 13 is still a certain distance from the welding point, and the bottom of the clamping plate 13 is still higher than the welding point. This design can prevent the clamping plate 13 from obstructing the welding operation of the welding gun and reserve enough space for the movement of the welding gun head. In some embodiments, this reserved distance is greater than half the height of the transverse partition.

[0020] In specific operation, before welding, adjust the rotating arm 6 to a horizontal position, then place the steel structure part 4 to be welded on the welding platform 1, level and position the steel structure part 4 to be welded, then slide the slider 5 to the welding point, and fix the slider 5 with bolts 10 and locking blocks 11, then pull out the stop rod 8, rotate the rotating arm 6 to a vertical position, then insert the stop rod 8 to fix the rotating arm 6, adjust the distance between the limit rods 9 on both sides inside the sliding chamber 12, insert the transverse partition to be welded between the clamping plates 13 to perform spot welding and positioning, and after spot welding is completed, directly perform overlay welding.
