Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to an automobile longitudinal beam processing fixture. Background Art

[0002] The automobile longitudinal beam is one of the important structural parts of the automobile, also known as the main beam. It is usually a rectangular or trapezoidal steel, installed at the bottom of the car body and connected to the frame at both ends. It mainly plays the role of supporting the car body and ensuring driving stability. The longitudinal beam directly bears the weight of the car body and transfers it to the frame and wheels. The existence of the longitudinal beam makes the car body form a solid whole, which helps to improve the vehicle's driving stability and handling performance.

[0003] According to publication number CN220408487U, a processing fixture for automobile longitudinal beams is disclosed, which relates to the technical field of automobile longitudinal beams, including a fixed seat, on which a rotating mechanism is arranged, and the rotating mechanism comprises a first drive motor, a rotating shaft, a first heat dissipation hole and a rotating box, wherein the first drive motor is fixedly mounted on the inner top of the fixed seat, and the output end of the first drive motor passes through the fixed seat. In the above application, the first drive motor is started by the arranged rotating mechanism and moving mechanism, so that the rotating box is driven to rotate, and then the clamped longitudinal beam is driven to rotate, so that the angle in the horizontal direction changes, which is convenient for operators to perform processing operations in multiple positions, and at the same time, the second drive motor is started to drive the square moving block to move, and then the clamped longitudinal beam is driven to move left and right, and through the joint cooperation between the rotating mechanism and the moving mechanism, there is no need to manually adjust the position of the longitudinal beam.

[0004] However, the above device still has shortcomings. By adopting the first moving mechanism and the second moving mechanism, the automobile longitudinal beam can be driven to move its position, thereby facilitating processing. However, the clamping mechanism fixes and clamps the longitudinal beam, and processing cannot be performed at the clamped position. It is necessary to manually contact and clamp, then manually move the longitudinal beam, and then clamp it again, and then process the previously clamped position again, which is very inconvenient.
