[0011] Reference Figures 1-4 The positioning device for welding steel structures is characterized in that it includes a fixed base 1 and a positioning plate 2 connected to the right edge of the upper surface of the fixed base 1. A buffer pad 3 is connected to the middle of the left side surface of the positioning plate 2. A support device 4 is slidably inserted into the left side of the upper surface of the fixed base 1. A movable clamping plate 5 is inserted into the middle of the upper part of the support device 4. A clamping cylinder 6 is connected to the middle of the upper surface of the support device 4. A clamping device 7 is slidably inserted into the middle of the lower edge of the rear surface of the support device 4.

[0012] In use, first place the fixed base 1 in a suitable position, then place the steel on the upper surface of the fixed base 1, and at the same time, make the end face of the steel contact the positioning plate 2 and cushion it with the buffer pad 3. Then push the support device 4 to move the support device 4 to a suitable position, then rotate the support device 4 to span the steel, and at the same time, the clamping device 7 penetrates the support device 4 and is inserted into the rear surface of the fixed base 1, and at the same time, clamp the support device 4 to prevent it from moving during clamping. Then, when the operator starts the clamping cylinder 6, the telescopic end on the clamping cylinder 6 extends, and at the same time, it drives the movable pressure plate 5 to move downward and clamp the steel. Then, place the welding part on the other end of the steel for welding. Finally, after the welding is completed, the operator starts the clamping cylinder 6 again to retract the telescopic end, and at the same time, the movable pressure plate 5 separates from the steel and pulls the welded steel to the left to pull it out from the support device 4.

[0013] After positioning, the support device can be quickly moved to the appropriate position on the fixed base 1 according to the steel of different lengths. At the same time, the extension length of the telescopic end of the clamping cylinder 6 can be controlled according to the thickness of the steel. The extension length of the telescopic end of the clamping cylinder 6 can be controlled by the existing air valve. The connection method and control between the clamping cylinder 6 and the air valve are existing technologies. The technical effect to be achieved by the present invention can be achieved by using existing technologies.

[0014] Furthermore, the fixed base 1 includes a base plate 1-1, a slot 1-2, a sliding groove 1-3, and a sliding column 1-4. Several slots 1-2 are evenly distributed in a horizontal row at the middle of the rear surface of the base plate 1-1. A sliding groove 1-3 is provided on the left side of the front edge of the upper surface of the base plate 1-1. A sliding column 1-4 is connected between the left and right surfaces inside the sliding groove 1-3. The positioning plate 2 is connected to the upper surface of the base plate 1-1.

[0015] When in use, place the steel on the upper surface of the base plate 1-1 and position it in contact with the positioning plate 2. When pushing the support device 4, the front end of the support device 4 slides and adjusts its position in the slide groove 1-3 and on the slide column 1-4. After adjustment, when the support device 4 is rotated, the clamping device 7 is inserted into the slot 1-2 and locked in place when it is aligned with the position of the slot 1-2.

[0016] Furthermore, the support device 4 includes a bracket 4-1, a through hole 4-2, an insertion hole 4-3, and a side groove 4-4. The bracket 4-1 has a through hole 4-2 at the lower front corner of its right side surface, and an insertion hole 4-3 at the middle of the lower edge of its rear surface. The insertion hole 4-3 has symmetrical side grooves 4-4 at the middle of its front and rear surfaces. The bracket 4-1 is concave in shape. The lower front edge of the bracket 4-1 is inserted into the sliding groove 1-3, and the sliding column 1-4 is inserted into the insertion hole 4-3. The position of the insertion hole 4-3 corresponds to the position of the slot 1-2. The telescopic end of the clamping cylinder 6 penetrates the upper surface of the bracket 4-1 and connects to the movable clamping plate 5.

[0017] In use, the operator pushes the bracket 4-1 so that the front end of the bracket 4-1 slides in the slide groove 1-3, while the through hole 4-2 slides on the slide column 1-4. When the bracket 4-1 moves to the appropriate position, the operator rotates the bracket 4-1 so that the bracket 4-1 rotates in the slide groove 1-3 with the slide column 1-4 as the pivot. Finally, when the insertion hole 4-3 is aligned with the card slot 1-2, the clamping device 7 is inserted into the card slot 1-2 and clamped.

[0018] Furthermore, the clamping device 7 includes a clamping plate 7-1, insert pins 7-2, springs 7-3, and pull holes 7-4. Insert pins 7-2 are symmetrically connected to the middle of the front of the left and right side surfaces of the clamping plate 7-1. Springs 7-3 are connected to the middle of the rear surface of each insert pin 7-2. Pull holes 7-4 are provided in the middle of the rear edge of the upper surface of the clamping plate 7-1. The front edge of the lower surface of the clamping plate 7-1 is sloping. The clamping plate 7-1 is inserted into the insert holes 4-3. The insert pins 7-2 are inserted into the side grooves 4-4. The rear end of the springs 7-3 is connected to the rear surface of the side grooves 4-4.

[0019] In use, when the bracket 4-1 rotates, the front edge of the lower surface of the clamping plate 7-1 is sloping. When the clamping plate 7-1 contacts the rear edge of the upper surface of the base plate 1-1, it pushes the clamping plate 7-1. At the same time, the clamping plate 7-1 slides backward in the insertion hole 4-3, and the insertion post 7-2 moves backward in the side groove 4-4. Then, when the clamping plate 7-1 is aligned with the slot 1-2, the spring 7-3 pushes the insertion post 7-2 forward in the side groove 4-4. At the same time, the insertion post 7-2 drives the clamping plate 7-1 forward in the insertion hole 4-3, and inserts the clamping plate 7-1 into the slot 1-2 to lock the bracket 4-1.

[0020] When opening bracket 4-1, the operator inserts their finger into the pull hole 7-4 and pulls it backward, while simultaneously pulling the front end of the card plate 7-1 out of the card slot 1-2. Finally, the bracket 4-1 is rotated upward.

[0021] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
