Abstract
Description
Technical Field
[0001] This utility model relates to the field of longitudinal beam production and transfer technology, specifically to an automobile longitudinal beam loading and unloading mechanism. Background Technology
[0002] With the development of intelligent automated production lines, especially in the field of vehicle longitudinal beam production, the magnetic loading and unloading transfer technology of vehicle longitudinal beam production lines has not only significantly improved production efficiency and product quality, but also effectively reduced production costs.
[0003] During the loading and unloading of longitudinal beams using the magnetic suction unit, the longitudinal beams may exhibit slight bouncing due to the attraction generated by the magnetic suction unit when adsorbing the beams, as well as the weight and material properties of the beams themselves. This bouncing phenomenon can easily lead to instability of the contact surface during magnetic suction, and it can also cause instability of the contact surface when subjected to external impacts or vibrations.
[0004] Therefore, it is necessary to optimize the structure of the loading and unloading device, such as by adding a buffer device, which can effectively reduce the bouncing of the longitudinal beam during magnetic loading and the impact or vibration. Furthermore, there is a certain height difference between the two ends of the bent longitudinal beam. Due to this height difference, the different buffering forces during magnetic extraction can easily cause an imbalance in the force on the longitudinal beam, potentially leading to misalignment during loading.
[0005] Therefore, the instability of the magnetic contact surface caused by the above reasons leads to detachment. Thus, during the feeding process, it is necessary to ensure good contact between the magnetic suction device and the longitudinal beam to reduce interference caused by bouncing, height differences, impacts, or vibrations.

[0008] The buffer frame includes a connecting plate, a T-shaped guide shaft, and, from top to bottom, a support spring, a spherical bearing, a limit spring, a spring seat, a buffer spring, a limit nut, and a locking nut, all sequentially fitted onto the T-shaped guide shaft.

The buffer frame passes through mounting bracket one and mounting bracket two at corresponding positions via the T-shaped guide shaft, and the buffer frame is clamped to mounting bracket one and mounting bracket two at corresponding positions via the limit nut and the locking nut.
[0009] Preferably, the lower end of the T-shaped guide shaft is threaded with a limiting nut and a locking nut, and the installation positions of the limiting nut and the locking nut are adjustable along the thread section.
[0010] Preferably, the stiffness coefficients of the support spring and the limiting spring are greater than the stiffness coefficient of the buffer spring.
[0011] Preferably, the height difference between the magnetic suction parts of mounting bracket one and mounting bracket two is the same as the height difference of the longitudinal beam.
[0012] Preferably, the lifting frame is slidably installed via the mounting groove of the guide rail and the connecting plate, and the connecting plate is provided with locking bolts to lock and fix it on the guide rail.
