Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, and in particular to a welding fixture for a double-wing extended box frame. Background Technology

[0002] A double-wing expansion box typically refers to a box-type device with an expandable structure on both sides. It is commonly used in scenarios where flexible adjustment of internal space is required, such as special vehicles (RVs, engineering vehicles): by unfolding or retracting the two sides (wings), the usable space of the vehicle compartment can be expanded. "Welding fixtures" are special tools for welding and assembling the frame of a double-wing expansion box. Their main functions are as follows: precise positioning and clamping, control of welding deformation, and facilitating welding operations. The frame welding fixture of the double-wing expansion box is a key process equipment in its production process. Its core objective is to ensure the dimensional accuracy, structural strength, and reliability of the expansion function of the frame through precise positioning, reliable clamping, and deformation control.

[0003] In the existing technology, when producing the frame of a twin-wing expansion box, welding fixtures are required to position and clamp the frame. However, when producing twin-wing boxes of different sizes, such as when the width of the main frame changes from 1.2m to 1.5m, the positioning blocks need to be manually disassembled and reinstalled, and the clamping point position needs to be adjusted. Each changeover takes a long time, which seriously affects the efficiency of small-batch, multi-variety production. The operation is cumbersome and inconvenient to use. Therefore, there is an urgent need for a welding fixture for twin-wing expansion box frames to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a welding fixture for a double-wing extended box frame.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A welding fixture for assembling a double-wing extended box frame includes a base plate, a frame on the top surface of the base plate, and a positioning component for positioning, assembling, and welding the frame.

[0023] Reference Figures 1-5 A welding fixture for assembling a double-wing extended box frame includes a base plate 1, a frame 2 on the top surface of the base plate 1, and a positioning assembly for positioning, assembling, and welding the frame 2. The positioning assembly is located on the top surface of the base plate 1 and includes: a fixed rail 4, which is fixedly installed on the top surface of the base plate 1; two support platforms 3 on the top surface of the base plate 1; several rotating wheels 5 installed inside the support platforms 3; the rotating wheels 5 are movably connected to the fixed rails 4; and fixing holes 6 are opened on the top surface of the support platforms 3. Mounting grooves 7 are respectively opened on both sides of the interior of the fixing holes 6. A first drive motor 8 is fixedly connected to the fixed hole 6. Two first threaded posts 9 are fixedly installed at both ends of the drive shaft of the first drive motor 8. Two clamping plates 10 are movably connected inside the fixed hole 6. A first threaded hole 11 is opened on one side of the clamping plate 10. The inner circular wall of the first threaded hole 11 is threadedly connected to the first threaded post 9. A second threaded hole 13 is opened on one side of the support plate 3. A bidirectional lead screw 14 is threadedly connected to the inner circular wall of the second threaded hole 13. A second drive motor 15 is fixedly installed on one side of the base plate 1. One end of the drive shaft of the second drive motor 15 is fixedly installed to the bidirectional lead screw 14.

[0024] In this embodiment, several limiting plates 17 are fixedly installed on the top surface of the base plate 1. The limiting plates 17 are movably connected to the bidirectional lead screw 14. Several baffles 12 are fixedly installed on one side of the support plate 3. Two moving platforms 16 are provided on the top surface of the base plate 1.

[0025] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0026] When the user needs to weld the expansion box frame 2 using the base plate 1, the second drive motor 15 is activated to drive the bidirectional lead screw 14 to rotate. This converts the rotational motion of the bidirectional lead screw 14 into linear motion through the second threaded hole 13. The support platform 3 then moves under the support of several fixed rails 4 and rotating wheels 5. The rotating wheels 5 ensure smooth movement of the support platform 3, allowing the distance between the support platforms 3 to be adjusted to near the length of the frame 2. The two long sides of the frame 2 to be welded are placed on the top surface of the support platform 3, and the moving platform 16 is manually pushed to support the bottom of the frame 2. The other two wide sides of the frame 2 are then placed on the top surface of the support platform 3, assembling a complete frame. Then, the first drive motor 8 is activated to drive the first threaded column 9 to rotate. The threaded column 9 and the first threaded hole 11 convert the rotational motion into linear motion, allowing the two clamping plates 10 to limit and position the two sides of the frame 2. At the same time, the second drive motor 15 is activated to drive the support plate 3 to move, so that the baffle 12 on the top surface of the support plate 3 clamps the other two sides of the frame 2. Thus, the frame 2 can be initially and tightly connected together, and then the welding personnel can perform welding operations, achieving the effect of positioning and welding the frame 2. By moving the support plate 3, the support plate 3 can be adapted to the length of the frame 2. By adjusting the two clamping plates 10, they can be adapted to the width of the frame 2. Thus, together with the baffle 12 and the clamping plates 10, the frame 2 can be assembled and positioned, which is convenient for the user to weld. When producing frames 2 of different sizes, it can be quickly adjusted without the need for manual operation of many parts, making it convenient to use and quite practical.
