Description

Technical Field

[0001] The utility model relates to the technical field of longitudinal beam processing, in particular to an adjustable fixture for longitudinal beam forming and welding. Background Art

[0002] The vehicle frame is the most important load-bearing component in an automobile, and the longitudinal beam of the vehicle frame is one of the key parts. Therefore, the longitudinal beam plays an important load-bearing role in the automobile. Side beam type vehicle frames, middle beam type vehicle frames, etc. of automobiles all contain longitudinal beams. Longitudinal beams are usually stamped from low alloy steel plates, and the cross-sectional shape is generally U-shaped, and some are made into Z-shaped or box-shaped cross-sections, etc. A fixture refers to a device used in the process of mechanical manufacturing to fix the processing object so that it occupies the correct position to receive construction or inspection. An adjustable fixture for longitudinal beam forming and welding is a device specially designed to support and fix workpieces (such as longitudinal beams) for welding processing. The adjustable fixture for longitudinal beam forming and welding is widely used in various manufacturing and construction fields, especially in occasions that require large-scale structure welding and assembly, such as the manufacturing of bridges, building structures, and mechanical equipment. By correctly selecting and using fixtures, production efficiency can be improved, errors can be reduced, and product quality can be improved.

[0003] When the existing adjustable fixture for longitudinal beam forming and welding is actually used, it is not convenient to fix longitudinal beams of different models and sizes.

[0004] After retrieval of existing patents: A welding fixture for positioning the rear longitudinal beam end plate of a floor assembly (publication number: CN203636275U), which is used to fix and support the left and right rear longitudinal beam end plates of the floor assembly, includes a cross beam, a threaded pin, and a pair of adjustable positioning surface components provided at both ends of the cross beam. The pair of adjustable positioning surface components can move on the cross beam to change the distance between the two, and the threaded pin is arranged on the adjustable positioning surface components. The left and right rear longitudinal beam end plates are respectively positioned and fixed on the adjustable positioning surface components through the threaded pins. Compared with the prior art, the utility model can determine the open size of the left and right rear longitudinal beam end plates by matching the threaded pins on the two groups of adjustable positioning surface components with the threaded holes of the left and right rear longitudinal beam end plates. In addition, due to the support of the cross beam, the Y-direction inclination and distortion of the left and right rear longitudinal beam end plates can be prevented, ensuring the control of the degrees of freedom of the parts, and having the advantages of simple operation, convenient loading and unloading, etc.

[0005] Although the above patent can prevent the Y-direction inclination and distortion of the left and right rear longitudinal beam end plates, ensuring the control of the degrees of freedom of the parts, and having the advantages of simple operation, convenient loading and unloading, etc., it is not convenient to offset the impact of the pressurized part, and the pressure rod directly acting on the surface of the longitudinal beam is easy to cause damage.

[0006] Therefore, it is very necessary to invent an adjustable fixture for longitudinal beam forming and welding to solve the above problems. Summary of the Utility Model

[0017] (III) Beneficial effects

[0018] The present utility model provides an adjustable fixture for longitudinal beam forming and welding, which has the following beneficial effects:

[0019] 1. For the adjustable fixture for longitudinal beam forming and welding, through the setting of the rotating assembly and the limiting assembly, during use, according to longitudinal beams of different models and sizes, place the longitudinal beam on the support seat, start the driving motor to drive the threaded rod to rotate, so that the sliding block slides on the support seat to limit the longitudinal beam, start the telescopic cylinder, push the pressure rod to rotate on the connecting seat, so that the pressure block presses down for fixation. At the same time, during installation, move the connecting seat so that the pressure block is directly opposite to the center of the cross-section of the longitudinal beam, twist the rotating rod to rotate within the fixed piece, and then the limiting block presses against the inner wall of the sliding groove, thereby achieving the fixed installation effect, facilitating the fixation of longitudinal beams of different models and sizes, and improving the stability and applicability of the adjustable fixture for longitudinal beam forming and welding.

[0020] 2. For the adjustable fixture for longitudinal beam forming and welding, through the setting of the buffer assembly, during downward pressing, the pressure generated by the downward pressing passes through the surface of the longitudinal beam and reversely presses against the pressure block, causing the pressure block to push the buffer spring. The buffer spring deforms and contracts under force and generates a rebounding force, thereby achieving the effect of offsetting part of the impact. At the same time, rotate the adjusting rod so that the adjusting rod rotates and lifts within the pressure rod to adjust the height, preventing the pressure rod from directly acting on the surface of the longitudinal beam and causing damage, and improving the safety and production quality of the adjustable fixture for longitudinal beam forming and welding.
