Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, specifically a riveting fixture for longitudinal beams of irregularly shaped vehicle bodies. Background Technology

[0002] See Figure 1 As shown, when riveting the longitudinal beams of the irregularly shaped vehicle body on the line, the unequal dimensions of the upper and lower flanges cause the center of gravity of the suspension to be inconsistent with the center of the workpiece, resulting in the longitudinal beams being skewed. During riveting, employees need to straighten the longitudinal beams before they can be riveted, which is physically demanding for employees, has low production efficiency, and is prone to rivet misalignment, posing a great quality risk. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a riveting fixture for the longitudinal beam of an irregularly shaped vehicle body, which is simple and quick to operate, reducing labor intensity while ensuring riveting quality and efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a riveting hanger for a non-standard vehicle body longitudinal beam, wherein the non-standard vehicle body longitudinal beam includes a vertical plate, the upper end of which is bent to form a first flat plate, and the lower end of which is bent to form a second flat plate, and the width of the first flat plate is greater than the width of the second flat plate. The riveting hanger includes a contour hook, which includes a lifting ring, a first hook body, and a second hook body. The first hook body includes a first vertical section, the lower end of which is bent inward to form a first horizontal section adapted to the second flat plate, and the top of the first horizontal section... The first vertical section has an inwardly bent upper end to form a first inclined section; the second hook includes a second vertical section, the lower end of which is bent inward to form a second horizontal section adapted to the first plate, and the top surface of the second horizontal section is the force-bearing surface supporting the first plate; the upper end of the second vertical section is bent inward to form a second inclined section, and the middle part of the second inclined section is hinged to the middle part of the first inclined section through a first hinge pin; the lifting ring is hinged to the ends of the first and second inclined sections respectively through connecting plates.

[0005] A further improvement is that the lifting ring includes a ring body, the lower end of which is provided with a connecting seat. The connecting seat is hinged to the upper ends of two connecting plates via a second hinge shaft. The lower end of one connecting plate is hinged to the end of the second inclined section via a third hinge shaft, and the lower end of the other connecting plate is hinged to the end of the first inclined section via a fourth hinge shaft.

[0006] A further improvement is that the connecting seat has a first mounting hole that is adapted to the second hinge shaft.

[0007] A further improvement is that a second mounting hole adapted to the first hinge shaft is provided in the middle of the first inclined section, and a third mounting hole adapted to the fourth hinge shaft is provided at the end of the first inclined section.

[0008] A further improvement is that a fourth mounting hole adapted to the first hinge shaft is provided in the middle of the second inclined section, and a fifth mounting hole adapted to the third hinge shaft is provided at the end of the second inclined section.

[0009] A further improvement is that the width of the first horizontal segment is greater than the width of the second flat plate, and the end of the first horizontal segment is bent upward to form a hook.

[0010] A further improvement is that it also includes a lifting mechanism, which includes a hook and a tension spring, wherein the lower end of the hook is connected to a lifting ring and the upper end of the hook is connected to the tension spring.

[0011] A further improvement is that the lower end of the hook is provided with a hook body that is compatible with the lifting ring, and the upper end of the hook is provided with a connecting ring.

[0012] A further improvement is that the lower end of the tension spring is connected to the hook via a first connecting hook.

[0013] A further improvement is that the upper end of the tension spring is connected to the overhead crane via a second connecting hook.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention designs a contour-following hook based on the cross-sectional dimensions of the longitudinal beam, employing a scissor-fork connection to clamp the longitudinal beam horizontally, ensuring perpendicular riveting of the flange and rivet head. A tension spring is installed on the hook, and its extension and retraction adjustment ensures vertical alignment of the rivet head and rivet center, facilitating riveting operations for workers. After this improvement, employee operation is simple and quick, reducing labor intensity while ensuring riveting quality and efficiency. Attached Figure Description
