Abstract

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.

Usually, when the marching fixtures are in use, the truck-mounted booms need to be adjusted to the correct position of the fixing frame. At the top, use bolts or buckles to fix the truck-mounted boom. When it is not aligned, it needs to be adjusted back and forth many times until it is aligned, and it takes a long time to lock it. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a fixing device that can adapt to the position of the boom in view of the problem that the existing truck-mounted boom fixing device requires multiple adjustments to the boom. [0...
