[0002] In modern industrial production, overhead conveyor lines are widely used in automobile manufacturing, logistics equipment, metal processing, and other fields due to their high efficiency and continuous conveying capabilities. The broad frame, as a key load-bearing component of the overhead conveyor line, is typically composed of multiple parts and requires welding for structural connection. However, overhead conveyor lines have a large number of broad frames (usually thousands), and traditional welding fixtures rely on manual calibration and adjustment of workpiece positions to ensure welding alignment accuracy. This process is time-consuming, resulting in a slow welding cycle and difficulty in improving production efficiency. Welding quality depends heavily on worker experience; worker proficiency directly affects weld quality, leading to high training costs and susceptibility to human error.

[0003] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] Technical Solution: To achieve the above objectives, this utility model provides a tooling fixture for positioning and welding broad frames, including a separable base, a positioning support system, a tensioning system, and a broad frame assembly. The separable base is rectangular, and the broad frame assembly is square. The positioning support system and the tensioning system are respectively connected to the top surface of the separable base, with the tensioning system connected to the center of the separable base. The positioning support system is located around the outer periphery of the tensioning system, and the broad frame assembly is placed on the top surface of the positioning support system. The positioning support system provides horizontal limitation and bottom support for the broad frame assembly. The tensioning system tensions and fixes the inner sidewall of the broad frame assembly. This utility model achieves rapid positioning and fixation of the broad frame assembly through the positioning support system and the tensioning system, improving welding accuracy and efficiency, and meeting the needs of mass production.

[0006] Furthermore, in the aforementioned tooling fixture for positioning the welding of the broad frame, the broad frame assembly includes a side plate and a middle plate. The side plate has a rectangular cross-section and an opening along its short side. The middle plate is welded to the outer wall of the side plate and is positioned perpendicular to the side wall of the side plate. The side plate is divided into a first folded plate and a second folded plate along the center line of its short side. The cross-sections of the first folded plate and the second folded plate are respectively U-shaped. Positioning holes are provided at the four corners of the middle plate. The positioning holes are used to cooperate with the positioning support system to achieve precise positioning.

[0007] Furthermore, in the aforementioned tooling fixture for positioning the welding frame, the positioning support system includes a support positioning seat and an auxiliary positioning seat. The support positioning seat has an inverted T-shaped axial section, and the auxiliary positioning seat is a hollow column. The support positioning seat and the auxiliary positioning seat are respectively connected to the top surface of the separable base by fasteners. The support positioning seat is located at the four corners of the tensioning system, and the auxiliary positioning seat is located at the middle of the long side of the separable base. The outer wall of the auxiliary positioning seat provides a limit for the surrounding plate. The top of the support positioning seat is a first support surface, and the top surface of the auxiliary positioning seat is a second support surface. The first support surface and the second support surface are located on the same horizontal plane, and the first support surface and the second support surface form support for the center plate. A positioning platform is located at the center of the first support surface, and the positioning platform is set corresponding to the positioning hole. The positioning platform extends into the positioning hole to form positioning.

[0008] Furthermore, in the aforementioned tooling fixture for positioning the welding of the frame, the top surface of the separable base is connected to an auxiliary support column by fasteners. Multiple auxiliary support columns are located on the outer periphery of the tensioning system, and the top surfaces of the multiple auxiliary support columns are located on the same horizontal plane.

[0009] Furthermore, in the aforementioned tooling fixture for positioning and welding the frame, the tensioning system includes a first tensioning mechanism, a second tensioning mechanism, and a third tensioning mechanism. The first tensioning mechanism is located in the middle of the separable base and tensions the long sides of the surrounding plate. The second and third tensioning mechanisms are respectively located at both ends of the first tensioning mechanism and together tension the short sides of the surrounding plate. The second and third tensioning mechanisms are mirror images of the center of the first tensioning mechanism.

The first tensioning block has an inclined surface on the side facing the long side of the enclosure plate, and the inclined surfaces on both sides are V-shaped. First sliders are slidably connected to the two sides of the inclined surface of the first tensioning block via dovetail grooves. A first push block is connected to the side of the first slider away from the first tensioning block, and the first push block is a cuboid arranged along the long side of the enclosure plate. When the first tensioning block moves towards the first base block, the first push block moves away from the first tensioning block, thus tensioning the long side of the enclosure plate.

A vertically arranged dovetail groove is located on the side of the fixing block closest to the second tensioning block, and the fixing block and the second tensioning block are vertically slidably connected via the dovetail groove. The side of the second tensioning block furthest from the fixing block is an inclined surface sloping upwards towards the surrounding plate. A second slider is located on the side of the second tensioning block furthest from the fixing block, and the second slider is slidably connected to the second tensioning block via the dovetail groove. A second push block is connected to the side of the second slider furthest from the second tensioning block via fasteners. The second push block is a cuboid arranged along the short side of the surrounding plate. When the second tensioning block moves towards the second base block, the second slider moves away from the second tensioning block, tensioning the short side of the surrounding plate.

[0012] Furthermore, in the aforementioned tooling fixture for positioning the welding frame, the positioning platform includes a pair of first positioning platforms and a pair of second positioning platforms. The pair of first positioning platforms are arranged along the short side of one side of the separable base, and the pair of second positioning platforms are arranged along the short side of the separable base away from the first positioning platforms.
