[0052] The working principle of the automatic fender assembly equipment of the automobile assembly line is as follows:

[0053] In the first step, the operator completes the fender assembly on the clamp. The operator places the screw on the tightening gun, places the fender on the clamp, the vacuum suction cup adsorbs the plate, the seventh cylinder extends, the clamp unit clamps, and the operator completes the assembly.

[0054] In the second step, the automobile assembly line transports the automobile body-in-white from the previous station to the fender assembly station.

[0055] In the third step, the engine cover is opened. The first cylinder and the second cylinder retract, the third cylinder extends, the fourth and fifth cylinders extend, and the cylinders drive the end guide block to lift the engine cover.

[0056] In the fourth step, the clamp is turned over and slides into the assembly position. The indexing table rotates to drive the clamp to turn over and change position to the body-in-white direction. The sixth cylinder extends to drive the clamp to move to the fender assembly position. The locking cylinder extends to combine the fender and the body-in-white into a whole.

[0057] In the fifth step, the tightening gun is automatically assembled. The eighth cylinder extends, the tightening gun rotates, and the screw installed on the tightening gun is screwed into the body-in-white from the fender direction. After tightening, the eighth cylinder retracts to drive the tightening gun to return to the original position. The vacuum suction cup releases the adsorption of the plate, and the seventh cylinder retracts to open the clamp unit.

[0058] In the sixth step, the clamp slides and turns over to the upper part position. The locking cylinder retracts, the clamp structure is unlocked with the base, the sixth cylinder retracts, and the cylinder drives the clamp to slide to the upper part position. The indexing table rotates to drive the clamp to turn over and change position to the operator's upper part position.

[0059] Step 7, the engine hood is lowered. The fourth and fifth cylinders are retracted, the third cylinder is retracted, and the engine hood is automatically lowered into place. The first and second cylinders are extended.

[0060] Step 8, the automobile assembly line transports the automobile body from the fender assembly station to the next station.

[0061] The above steps constitute the basic cycle steps of the fender automated assembly of the assembly line.

[0062] In use, to ensure force balance, a counterweight structure 7 is fixed on the opposite side of the rotating frame to the fender assembly fixture, to ensure force balance during rotation of the rotating frame.
