Description

Technical Field

[0001] This utility model belongs to the field of steel welding technology, and specifically relates to a steel welding positioning fixture. Background Technology

[0002] Steel welding positioning fixtures are tools used to fix the position of steel and ensure precise alignment and angle during the welding process. They typically use mechanical structures to hold the workpiece and clamping devices to achieve fixation.

[0003] Currently, common steel welding positioning fixtures, such as those for steel pipes, L-shaped steel, and I-shaped steel, typically use clamps to hold and fix one piece of steel during welding. Then, the other piece of steel is aligned and joined by hand before welding. However, this hand-alignment welding method has low stability. Some fixtures use a double-clamp structure to fix two pieces of steel separately before alignment and joining, which offers relatively higher stability. However, the cutting angles of the steel end faces can vary during welding, resulting in different alignment angles. Most current double-clamp structures are fixed to the worktable, making angle adjustment and alignment difficult. They also cannot be flipped for easy welding of the joints, usually requiring the steel to be removed, flipped, and then welded, which is quite cumbersome. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a steel welding positioning fixture, which solves the problem that when welding steel, the cutting angle of the steel end face is sometimes different, and therefore the alignment angle will also be different. Most current double clamp structures are fixed on the table, which is not convenient for angle adjustment and alignment, and is not convenient for flipping and welding the joint of the steel. Generally, the steel needs to be removed, flipped and then welded, which is quite troublesome.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a steel welding positioning fixture, comprising a placement plate, wherein a clamping mechanism is symmetrically and rotatably arranged on the upper side of the placement plate, the clamping mechanism comprising an L-shaped clamping block, a fixing block, a first screw, a side block, and a second screw. The L-shaped clamping block is rotatably arranged on the upper side of the placement plate, and a fixing block is fixedly arranged at one end of the upper side of the L-shaped clamping block. The first screw is threadedly connected to the side of the fixing block, and the first screw threaded through the fixing block to the upper side of the L-shaped clamping block. A side block is fixedly arranged on the upper side of the side of the L-shaped clamping block away from the fixing block, and a second screw is threadedly connected to the upper side of the side block, and the second screw threaded through the side block to the lower side. The lower end of the second screw is pressed against the upper side of the placement plate, and steel is clamped on the upper side of the L-shaped clamping block by the first screw.

[0006] The beneficial effects of this utility model are as follows: when welding steel, two steel pieces can be fixed at the same time, and the angle of the L-shaped clamp can be freely adjusted horizontally according to the cutting angle of the steel ends, thereby driving the steel to rotate, so that the steel can be joined according to the cutting angle of the ends and remain stable, greatly increasing the convenience of steel welding.

[0007] In order to disassemble and replace the clamping mechanism;

[0008] As a further improvement to the above technical solution: a screw rod three is fixedly installed in the lower middle part of the L-shaped clamping block, and the screw rod three passes through the placement plate and is threaded to the lower side to be connected to a nut.

[0009] The beneficial effects of this improvement are as follows: a screw rod is provided on the lower side of the L-shaped clamping block. The screw rod passes through to the lower side of the placement plate and is threadedly connected to the nut. The nut does not need to be tightened, so that the L-shaped clamping block can rotate on the placement plate. This allows the clamping mechanism to be disassembled and replaced.

[0010] To increase the stability of the L-shaped clamping block;

[0011] As a further improvement to the above technical solution: the upper side of the placement plate is a rough frosted surface.

[0012] The beneficial effects of this improvement are: the upper side of the placement plate is a rough frosted surface, which facilitates the increase of the stability of the screw two pressing with the placement plate, thereby increasing the stability of the L-shaped clamping block.

[0013] To facilitate the flipping and welding of the steel;

[0014] As a further improvement to the above technical solution: connecting blocks are fixedly provided at both ends of one side of the placement plate, and a sleeve rod is rotatably provided on the side of the connecting blocks that is far away from each other. A locking knob is threadedly connected to the side of the sleeve rod that is far away from the connecting blocks. The locking knob is threaded through the sleeve rod and pressed against the connecting block. A fixing rod is provided at the lower end of the sleeve rod, and a foot rod is fixedly provided at the lower end of the fixing rod.

[0015] The beneficial effects of this improvement are as follows: by rotating the connecting block and the sleeve rod, and tightening the connecting block with the locking knob, the placement plate can be rotated up and down, thereby driving the stable steel to rotate, which facilitates the flipping and welding of the steel.

[0016] To increase the placement stability of this device;

[0017] As a further improvement to the above technical solution: a crossbar is fixedly provided between the foot rods.

[0018] The beneficial effect of this improvement is that a crossbar is fixed between the legs, which increases the stability of the device.

[0019] To facilitate adjustment of welding height as needed;

[0020] As a further improvement to the above technical solution: the upper end of the fixing rod is inserted into the sleeve rod, and a bolt is threaded on the lower side of the sleeve rod, the bolt passing through the sleeve rod and pressing it against the fixing rod.

[0021] The beneficial effects of this improvement are: the fixed rod and the sleeve rod are inserted together, and the height of the sleeve rod can be adjusted up and down, thereby adjusting the height of the placement plate. Then, the sleeve rod is fixed by tightening the bolts, which makes it easy to adjust the welding height as needed.

[0022] To avoid affecting the flipping welding;

[0023] As a further improvement to the above technical solution: the placement plate includes a partition plate and a side plate, there is a gap between the partition plates, and the side plate is fixedly connected to one side of the partition plate near the connecting block.

[0024] The beneficial effects of this improvement are as follows: the placement plate includes a sub-plate and a side plate, with a gap between the sub-plates. The side plate is fixedly connected to the side of the sub-plate near the connecting block, and there is a gap between the sub-plates. In this way, when two steel bars are welded in a straight line, the placement plate will not block the lower side of the steel bars, thus avoiding affecting the flipping welding.

[0025] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0032] like Figure 1 — Figure 4As shown: A steel welding positioning fixture includes a placement plate 1. A clamping mechanism 2 is symmetrically and rotatably mounted on the upper side of the placement plate 1. The clamping mechanism 2 includes an L-shaped clamping block 21, a fixing block 22, a first screw 23, a side block 25, and a second screw 26. The L-shaped clamping block 21 is rotatably mounted on the upper side of the placement plate 1. A fixing block 22 is fixedly mounted on one upper end of the L-shaped clamping block 21. A first screw 23 is threadedly connected to the side of the fixing block 22, and the first screw 23 threadedly passes through the fixing block 22 to the upper side of the L-shaped clamping block 21. A side block 25 is fixedly mounted on the upper side of the side of the L-shaped clamping block 21 away from the fixing block 22. A second screw 26 is threadedly connected to the upper side of the side block 25, and the second screw 26 threadedly passes through the side block 25 to the lower side. The lower end of screw 26 is pressed against the upper side of the placement plate 1. A steel member 3 is clamped on the upper side of the L-shaped clamping block 21 by screw 23. During welding of the steel members 3, two steel members 3 can be fixed simultaneously. The angle of the L-shaped clamping block 21 can be freely adjusted horizontally according to the cutting angle of the steel member 3's end, thereby driving the steel member 3 to rotate. This allows the steel members 3 to be joined according to the cutting angle of their ends and maintain stability, greatly increasing the convenience of welding the steel members 3. A screw 27 is fixedly installed in the middle of the lower side of the L-shaped clamping block 21. The screw 27 passes through the placement plate 1 and is threaded to the lower side where a nut 28 is connected. The screw 27 is installed on the lower side of the L-shaped clamping block 21, and it passes through the placement plate 1 and is threaded to the nut 28. The nut 28 does not need to be tightened; the L-shaped clamping block 21 can rotate on the placement plate 1, allowing the clamping mechanism 2 to be disassembled and replaced. The upper side of the placement plate 1 has a rough frosted surface, which increases the stability of the screw 26 pressing against the placement plate 1, thereby increasing the stability of the L-shaped clamping block 21. Connecting blocks 4 are fixedly installed at both ends of one side of the placement plate 1. A sleeve rod 5 is rotatably installed on the side of the connecting blocks 4 that is away from each other. A locking knob 6 is threadedly connected to the side of the sleeve rod 5 that is away from the connecting blocks 4. The locking knob 6 is threaded through the sleeve rod 5 and pressed against the connecting blocks 4. A fixing rod 7 is installed at the lower end of the sleeve rod 5, and a foot rod 9 is fixedly installed at the lower end of the fixing rod 7. Block 4 is rotatably connected to sleeve rod 5, and the connecting block 4 is tightened and fixed by locking knob 6. The placement plate 1 can be rotated up and down, thereby driving the stable steel 3 to rotate, which facilitates the flipping and welding of steel 3. A crossbar 10 is fixedly installed between the foot rods 9 to increase the placement stability of the device. The upper end of the fixing rod 7 is inserted into sleeve rod 5. A bolt 8 is threaded to the lower side of sleeve rod 5. The bolt 8 passes through sleeve rod 5 and presses against fixing rod 7. The fixing rod 7 is inserted into sleeve rod 5, and the height of sleeve rod 5 can be adjusted up and down, thereby adjusting the height of placement plate 1. Then, the sleeve rod 5 is fixed by tightening bolt 8, which facilitates the adjustment of welding height as needed. The placement plate 1 includes a partition plate and a side plate.The partition plates have a gap between them, and a side plate is fixedly connected to the side of each partition plate near the connecting block 4. The placement plate 1 includes partition plates and side plates, with a gap between them. This gap ensures that when two steel pieces 3 are welded in a straight line, the placement plate 1 will not obstruct the lower side of the steel piece 3, thus avoiding interference with the flipping welding.

[0033] Working principle and usage process of this utility model:

[0034] In use, place the steel piece 3 on the upper side of the L-shaped clamp 21, then turn the screw 23 to contact the steel piece 3. Next, according to the cutting angle of the steel piece 3's end, rotate the L-shaped clamp 21 to bring the ends of the steel piece 3 that need to be welded closer together, and simultaneously push the steel piece 3, causing it to slide relative to the L-shaped clamp 21. Finally, the ends of the steel piece 3 are aligned and joined. Tighten the screw 23 to press the steel piece 3 firmly. Simultaneously, tighten the screw 26, causing its lower end to press against the upper side of the placement plate 1. When steel 3 is fixed relative to clamping mechanism 2, and clamping mechanism 2 is fixed relative to placement plate 1, the end joint of steel 3 will remain stable. Then, the joint of steel 3 can be welded. When steel 3 is welded, two steel 3 can be fixed at the same time. The angle of L-shaped clamp 21 can be freely adjusted horizontally according to the cutting angle of the end of steel 3, thereby driving steel 3 to rotate. This allows steel 3 to be joined according to the cutting angle of the end and remain stable, greatly increasing the convenience of welding steel 3.

[0035] In addition, a screw 27 is provided on the lower side of the L-shaped clamping block 21. The screw 27 passes through to the lower side of the placement plate 1 and is threadedly connected to the nut 28. The nut 28 does not need to be tightened, so that the L-shaped clamping block 21 can rotate on the placement plate 1, thereby allowing the clamping mechanism 2 to be disassembled and replaced.

[0036] In addition, the upper side of the placement plate 1 is a rough frosted surface, which helps to increase the stability of the screw 26 pressing against the placement plate 1, thereby increasing the stability of the L-shaped clamp 21.

[0037] In addition, the connecting block 4 is rotatably connected to the sleeve rod 5, and the connecting block 4 is tightened and fixed by the locking knob 6. The placement plate 1 can be rotated up and down, thereby driving the stable steel 3 to rotate, which facilitates the flipping and welding of the steel 3.

[0038] In addition, a crossbar 10 is fixedly installed between the foot rods 9 to increase the placement stability of the device.

[0039] In addition, the fixing rod 7 is inserted into the sleeve rod 5, and the height of the sleeve rod 5 can be adjusted up and down, thereby adjusting the height of the placement plate 1. Then, the sleeve rod 5 is fixed by tightening the bolt 8, which makes it easy to adjust the welding height as needed.

[0040] In addition, the placement plate 1 includes a sub-plate and a side plate, with a gap between the sub-plates. The side plate is fixedly connected to the side of the sub-plate near the connecting block 4. The gap between the sub-plates ensures that when the two steel bars 3 are welded in a straight line, the placement plate 1 will not block the lower side of the steel bars 3, thus avoiding affecting the flipping welding.
