(2) preliminary clamping detection
After the elastic damping contact support is completed, a certain air pressure is filled into an air flow cavity (401) of the clamping propulsion body (4), and a distance sensing module (601) senses and detects the initial clamping distance of the guide piston (8) and sets the initial clamping distance as { Lb1, lb2, lb3, & gt, lbn };
(3) detecting distance dispersion
Performing difference analysis on the preliminary clamping distance and the preliminary mounting distance of the guide piston (8) in the control system, and setting a difference set as { Lc1, lc2, lc3, & gt, lcn }, wherein lc1=lc1-La 1, lc2=lc2-La 2, lc3=lc3-La 3, & gt, lcn=lbn-Lan;
the control system performs accumulated calculation on the distance difference sum, and if the distance difference sum is Lm, the distance difference sum lm=lc1+lc2+lc3+ & Lcn;
(4) secondary clamping air pressure supplement
The control system supplements the secondary clamping air pressure to the air flow cavity (401) to a corresponding degree according to the sum of the distance differences, and if the air pressure increment of the secondary clamping air pressure supplementation is delta P, the air pressure increment delta P-delta sum of the distance differences Lm.
9. The control method of the self-adjusting large-specification workpiece milling and boring lathe is characterized by comprising the following steps of:
after the secondary clamping air pressure supplement is completed, the total air pressure filled into the air flow cavity (401) of the clamping propulsion body (4) is Pw, and Pw=Po+DeltaP, wherein Po is the air pressure filled into the air flow cavity (401) of the clamping propulsion body (4) during primary clamping detection.
