[0035] The clamping and flipping assembly platform described in the present invention has the following working process:

[0036] After the front axle of the mining wide-body dump truck is welded, it is transported to the assembly area through the workstation equipment, and the front axle is manually assisted to be hoisted to the clamping position, and the pre-tightening program is started. The piston and rod assembly of the clamping angle cylinder assembly 16 begin to be ejected, and the angle guide sleeve 19 is pushed to rotate around the outer sleeve 18 through the guide bolt 20 to drive the pressure plate 17 to start rotating. When the angle guide sleeve 16 reaches the required rotation angle, the rotation and clamping of the workpiece (front axle) is completed; then the flipping program is started, the cylinder assembly 28 is started, and the piston rod begins to retract. The main pull rod 31 on the main flip mechanism assembly 3 is pulled up through the cylinder coupling head 29 and the coupling head pin shaft 30, driving the connected lower pin shaft 32 of the front axle support seat to pull the front axle support seat 15 of the clamping flip mechanism 2 to rise, and at the same time, the side pull rod 33 on the side flip mechanism 4 and the connected upper pin shaft 34 of the front axle support seat assist in pushing the front axle support seat 15 of the clamping flip mechanism 2 to flip, until the main pull rod 33 leans against the rear limit block 10, completing the 180° flipping action of the clamping mechanism assembly 2; at this point, the clamping flip assembly table is in a waiting state.

[0038] If it is necessary to go offline directly, the workpiece (front axle) is pre-lifted manually, and the program is started. The piston and rod assembly in the clamping and installing angle cylinder assembly 16 begin to be retracted, and the angle guide sleeve 19 is pulled through the guide bolt 20 to guide the outer sleeve 18 to rotate, so as to drive the pressure plate 17 to start rotating. When the angle guide sleeve 16 rotates to the initial position, the rotation and release of the workpiece (front axle) are completed; at this point, the workpiece (front axle) can be manually lifted off the clamping mechanism assembly 2. After the workpiece (front axle) is lifted off, the rotation program is started again to continue working, waiting for the next clamping and flipping work.
