The invention discloses a self-adaptive marching fixing device for a vehicle-mounted suspension arm. The self-adaptive marching fixing device comprises a fixing frame (1), threaded sleeves (14) are arranged at the top ends of two stand columns of the fixing frame (1), rotary rods (3) are installed in the threaded sleeves (14), the two rotary rods (4) clamp a fixing base (3), and a pull ring (31) at the bottom of the fixing base (3) is connected with the fixing frame (1) through a tensioner (2). A tensioner structure is fixedly designed in the up-down direction, and the up-down direction can beadjusted. A screw precession type is designed in the left-right direction, the space gap in the left-right direction can be adjusted, and the requirement for adjustment in four directions is met. When the vehicle-mounted suspension arm returns, only fine adjustment is needed, the vehicle-mounted suspension arm can be fixed by roughly adjusting the truck-mounted suspension arm to the position above the fixing frame, fastening time is saved, and self-adaptive fixing is achieved.

    本发明公开了一种随车吊臂的自适应行军固定装置,包括固定架(1),固定架(1)的两根立柱的顶端有螺套(14),螺套(14)中安装旋杠(3),两个旋杠(4)夹持着固定座(3),固定座(3)底部的拉环(31)通过拉紧器(2)和固定架(1)联接。本发明将上下方向固定设计为拉紧器结构,可对上下方向进行调整;左右方向设计为螺杆旋进式,可对左右方向空间间隙进行调整,满足四个方位进行调整。当随车吊臂回位时,只需进行微调,将其大致调整在固定架上方就可进行固定,节约紧固时间,实现自适应固定。
