Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 2-6, the quick machining clamping mechanism for the main hinged structure of the loader comprises a base 2, four groups of clamping devices 4 and a pressing device 3 are arranged on the base, the clamping direction of the clamping devices 4 is transverse clamping, the clamping devices 4 are uniformly distributed on the base 2 according to a 2X2 array, each clamping device 4 comprises two groups of L-shaped supports 401 which are oppositely arranged, each L-shaped support 401 is fixedly arranged on the base 2 and forms a limiting groove after installation, a screw 404 is arranged on each L-shaped support 401, the side plates 101 are inserted into the limiting grooves in an inserted mode, and the screw 404 is rotated until the screws tightly abut against the side plates 101, so that clamping and fixing are achieved. The pressing devices 3 are provided in four groups, and are provided at both ends of the side plate 101.

The L-shaped bracket 401 is provided with a rib 402, and the rib 402 is triangular. The reinforcing ribs are applied to improve the stability of the L-shaped support 401 and avoid bending. The L-shaped bracket 401 is provided with a screw hole 405, the screw rod 404 is in threaded fit with the screw hole 405, and the end of the screw rod 404 is provided with a nut 403.

The pressing device 3 comprises a limiting rod 301, an adjusting nut 302 and a pressing block 303 are arranged on the limiting rod 301, and the pressing block 303 is limited below the adjusting nut 302. The pressing block 303 is long, a stroke groove 304 is formed in the pressing block 303, and the limiting rod 301 is inserted into the stroke groove. The limiting rod 301 is provided with a thread structure, and the adjusting nut 302 is in threaded connection with the limiting rod 301.
