Thus, when the transverse processor 4 and the vertical processor 5 complete the processing of one process, the next process is carried out, the tool needs to be replaced, and the position of the tool apron 22 on the rotating head 35 is adjusted, the tool apron motor 21 is started, and the tool apron motor 21 drives the reciprocating sleeve 33 to transversely move back and forth along the guide rail through the driving screw rod 34 when working; during the reciprocating movement of the reciprocating sleeve 33, the connecting disc 31 drives the push-pull rod 19 to move back and forth, so that the push-pull rod 19 drives the tool holder 22 to "retract" or "extend" along the radial slide rail 26 by "pulling" or "pushing" the extrusion block 23, thereby achieving the purpose of adjusting the position of the tool holder 22 on the rotating head 35. The transverse processor 4 and the vertical processor 5 can then enter the next working cycle.

This processingequipment that car hung arm compact structure, design benefit carry out a clamping back to the work piece, vertical processingequipment 5 and two sets of horizontal processingequipment 4 can be processed the work piece from three position synchronization, so this processingequipment clamping once can accomplish the processing work that the car hung the arm, has solved the low and low problem of machining efficiency of machining precision that current car hung the arm processing method and has had from this, has satisfied the user demand that the enterprise processed the car and hung the arm.
