Description

TECHNICAL FIELD

[0001] The utility model relates to the riveting frock technical field of automobile parts, more particularly to a steering column support assembly riveting frock. BACKGROUND

[0002] The existing steering column support assembly is mainly composed of an upper mounting bracket, a U-shaped fixing bracket and a connecting plate, and these key components jointly support and fix the steering column. However, the current assembly process mainly relies on manual operation, which has certain limitations. Since the precision of manual assembly is not easy to guarantee, the components of the support assembly may be misaligned or not fully seated during assembly, which may cause looseness or structural instability. Especially during vehicle driving, such assembly errors are prone to cause vibration and noise, which not only affects the driving experience, but also may have a negative impact on the overall safety of the vehicle. SUMMARY

[0003] The utility model aims at solving one of the technical problems in the related art to some extent. To this end, the utility model provides a steering column support assembly riveting frock, which can accurately fix the upper mounting bracket, the U-shaped fixing bracket and the connecting plate through the X, Y and Z directional cylinder clamping mechanisms, avoid misalignment, improve assembly precision and reduce human error.

[0004] The technical scheme adopted by the utility model is as follows: a steering column support assembly riveting frock is provided, which comprises a clamping mechanism, the clamping mechanism comprises a mounting plate, a cushion block, two first Z-direction clamping cylinders, a Y-direction clamping cylinder and two X-direction clamping cylinders, the cushion block is fixedly installed on the mounting plate, the first Z-direction clamping cylinder is used for reciprocating movement in the direction of abutting, so as to abut or disabut the upper mounting bracket with the cushion block, the Y-direction clamping cylinder is fixedly installed on the upper side of the mounting plate and is used for abutting or disabutting the connecting plate, and the two X-direction clamping cylinders are respectively fixed on the two sides of the mounting plate or the cushion block and are used for abutting or disabutting the U-shaped fixing bracket with the cushion block.

[0005] After the above structure is adopted, the riveting frock can significantly improve the assembly precision of the steering column support assembly. By using multiple cylinders in the clamping mechanism, the frock can realize multi-directional clamping and positioning of the upper mounting bracket, the U-shaped fixing bracket and the connecting plate. These cylinders are respectively controlled in X, Y and Z directions, ensuring that each component can be accurately fixed at the predetermined position during assembly, avoiding misalignment problems that may occur during manual assembly.

[0006] Firstly, the Z-direction clamping cylinder ensures the reliable contact and positioning of the upper mounting bracket and the cushion block, thereby avoiding vibration and noise caused by looseness or incomplete positioning during assembly. At the same time, the Y-direction clamping cylinder can provide accurate positioning for the connecting sheet, so that it forms a firm connection with other components. The two X-direction clamping cylinders are respectively fixed on both sides of the tooling, and through synchronous action, they clamp the U-shaped fixing frame to ensure its stability during assembly.

[0007] This innovative riveting tool replaces manual assembly with automated operation, not only improving production efficiency, but also significantly reducing human error and ensuring the stability and consistency of assembly quality. After optimizing the assembly process, the noise problem of the steering column support assembly can be effectively reduced, improving the driving comfort and safety of the vehicle.

[0008] According to an embodiment of the present application, the riveting tool further comprises a base, and the mounting plate is rotatably mounted on the base; allowing workers to flexibly adjust the inclination angle of the clamping mechanism according to actual needs. The operation convenience of the tooling is improved, and workers can more easily perform riveting operations, ensuring that the riveting process is smoother and more efficient, while reducing operation errors caused by inconvenient posture or angle errors, further improving assembly quality and production efficiency.

[0009] According to an embodiment of the present application, one end of the support rod is hinged to the mounting plate or the cushion block, and the other end of the support rod abuts against the base; forming a stable support structure. The design of the support rod ensures that the mounting plate can maintain sufficient support force when adjusting the angle, and will not cause the plate surface to lose stability or displace due to changes in the inclination angle.

[0010] According to an embodiment of the present application, the clamping mechanism further comprises a second Z-direction clamping cylinder, which is fixedly installed on the mounting plate or the cushion block, and is used for abutting or un-abutting the U-shaped fixing frame with the upper mounting bracket; the cylinder ensures that the U-shaped fixing frame can reliably adhere to the upper mounting bracket during assembly by acting along the Z-direction, thereby improving the contact stability of the two. Compared with a single clamping cylinder, the first Z-direction clamping cylinder and the second Z-direction clamping cylinder respectively clamp and fix from both sides of the upper mounting bracket, effectively reducing assembly errors.

[0011] According to an embodiment of the present application, the cushion block is provided with a through hole, and the piston rod of the second Z-direction clamping cylinder is in sliding fit with the through hole; the piston rod of the second Z-direction clamping cylinder is retracted into or extended out of the through hole.

[0012] According to an embodiment of the present application, the moving end of the Y-direction clamping cylinder is hinged with a clamping cross bar, and the two ends of the clamping cross bar respectively abut against the U-shaped fixing frame.

[0013] According to one embodiment of the utility model, the cushion block has a riveting hole, when the upper mounting bracket and the connecting sheet are riveted through the pull riveter, the pull rivet extends into the riveting hole, and the riveting hole is arranged to avoid interference of the cushion block on the pull rivet.

[0014] According to one embodiment of the utility model, the cushion block has a positioning protrusion, and the positioning protrusion is matched with the waist-shaped hole on the upper mounting bracket. DRAWINGS
