Description

Technical Field

[0001] This utility model relates to the field of lightweight board production technology, specifically to a positioning device for frame welding. Background Technology

[0002] Existing lightweight panel production frame assembly, such as Figure 4 As shown, the frame is assembled and welded from two short plates 13 and two long plates 14. The lower end of the frame has two parallel frame legs 17, and the upper end has a flange 16 that can be engaged with the two frame legs 17. Therefore, the assembled frame is usually used as a positioning tool during the production of the frame.

[0003] The long plate 14 of the frame is a U-shaped plate, and the short plate 13 is an L-shaped plate. Several stops are welded to the side wall of the positioning tool. The lower end face of the long plate 14 is placed on the positioning tool, and the stops and flanges 16 abut against the sides of the long plate 14 to limit its position. The upper end face of the short plate 13 has a mounting groove 15 that can mate with a corner of the upper end face of the long plate 14. Therefore, during assembly, the side wall of the short plate 13 is abutted against the long plate 14, and the mounting groove mates with the upper end face of the long plate 14 to achieve the positioning of the short plate 13.

[0004] Because the long plate is not fully positioned, it can still move along its length during welding. To ensure welding quality, two workers are required at both ends of the positioning tool to simultaneously assemble and weld the two short plates 13, and constantly adjust the position of the two long plates 14 to prevent displacement and ensure alignment of the two ends. This results in low welding efficiency and some errors during assembly.

[0005] To address the problems existing in the prior art, this utility model designs and manufactures a positioning device for frame welding to overcome the aforementioned defects. Summary of the Invention

[0006] To address the problems existing in the prior art, this utility model provides a positioning device for frame welding, which can improve assembly efficiency and reduce the labor intensity of workers.

Detailed Implementation

[0030] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0031] like Figure 1-3 The positioning device for welding a frame assembly shown includes a positioning table 1. A long plate positioning assembly is mounted on the upper surface of the positioning table 1. A fixing assembly and a moving assembly for positioning a short plate 13 are respectively mounted at both ends of the positioning table 1. The moving assembly can reciprocate along the length of the positioning table 1. A locking assembly is mounted on the long plate positioning assembly to restrict the movement of the moving assembly.

[0032] Specifically, after the two short plates 13 and the two long plates 14 are placed, the moving component is pushed to move along the direction of the fixed component. The moving component drives the ends of the two long plates 14 placed on the long plate positioning component to align and move towards the fixed component. Finally, the moving component enables the ends of the two short plates 13 and the long plates 14 to cooperate with each other.

[0033] The upper end face of the long plate 14 can be inserted into the mounting groove 15 of the short plate 13, and the side wall of the short plate 13 can also abut against the long plate 14 to form a closed rectangular frame. Then, the movement of the moving component is restricted by the locking component, and the short plate 13 and the long plate 14 are completely fixed and welded.

[0034] This invention enables rapid positioning and assembly, improving production efficiency and reducing the labor intensity of workers. The entire assembly frame will not shift during welding, effectively improving welding quality.

[0035] This utility model's long plate positioning assembly includes two horizontal bars 5 and two stop bar assemblies located on both sides of the positioning platform 1. Each stop bar assembly includes at least two vertical bars 4, which are fixed to the side wall of the positioning platform 1. Both horizontal bars 5 are located between the two stop bar assemblies, and the distance between each horizontal bar 5 and the adjacent vertical bar 4 is the same as the width of the lower end face of the long plate 14. The long plate 14 can be placed between the adjacent horizontal bars 5 and the stop bar assemblies, achieving limiting positioning along the width direction of the positioning platform 1.

[0036] Specifically, both the fixed component and the moving component include an alignment plate 9 and two placement seats 8 that can position the short plate 13. The two placement seats 8 are installed on one side of the alignment plate 9. Each placement seat 8 includes a connecting block 2 and a support block 3. One side of the connecting block 2 is connected to the alignment plate 9, and the other side of the connecting block 2 is connected to the support block 3.

[0037] The sidewall of the short plate 13 of this invention can be inserted between the support block 3 and the connecting block 2, and the upper surface of the short plate 13 can be placed on the upper surface of the support block 3. The distance between the two mounting grooves 15 at the end of the short plate 13 is equal to the distance between the two support blocks 3 on opposite sides. The short plate 13 can be positioned by aligning the mounting grooves 15 with the support blocks 3.

[0038] Specifically, both ends of the crossbar 5 are flush with both ends of the positioning platform 1. The lengths of the crossbar 5 and the positioning platform 1 are equal to the length of the long plate 14. One side of the alignment plate 9 on the moving assembly, which is mounted on the mounting base 8, can contact the end of the crossbar 5. The end of the crossbar 5 can limit the movement of the moving assembly.

[0039] Specifically, the sides of the two placement seats 8 that are far apart from each other can contact the crossbar 5. The alignment plate 9 on the fixed component is fixedly connected to the crossbar 5. Each of the two placement seats 8 on the movable component is equipped with a connecting bracket 10, which is slidably connected to the crossbar 5. The crossbar 5 can limit the position of the long plate 14, and also connect the fixed component and the movable component, and guide the movable component.

[0040] The lower end face of the alignment plate 9 of this utility model is flush with the lower end face of the positioning platform 1. The end of the connecting frame 10 away from the placement seat 8 is provided with a slider 11. The crossbar 5 is provided with a groove 6 that cooperates with the slider 11. The groove 6 is parallel to the length direction of the positioning platform 1. The slider 11 is a cuboid and the groove 6 is a rectangle.

[0041] Specifically, the square slider 11 and the rectangular groove 6 work together to prevent the moving device from rotating around the slider 11 during movement. The lower end of the alignment plate 9 rests on the plane, which also helps to prevent the moving component from rotating. This prevents the short plate 13 from falling off due to the rotation and tilting of the moving component, thus avoiding safety hazards.

[0042] The locking assembly of this utility model includes two locking pins 12. Both the crossbar 5 and the slider 11 are provided with insertion holes 7. When the alignment plate 9 on the moving assembly abuts against the crossbar 5, the two insertion holes 7 are aligned, and the locking pins 12 are inserted into the two insertion holes 7 at the same time to lock the movement of the moving assembly.
