Body frame corrector

Abstract

A body frame corrector ( 1 ) capable of efficiently correcting a complicatedly deformed frame or the like and providing an excellent workability, comprising a frame-shaped body ( 2 ) for installing a deformed body frame ( 40 ) therein, a plurality of ceiling cylinders ( 7 ), floor cylinders ( 10 ), and side cylinders ( 9 ) disposed on the ceiling surface, floor surface, inner side surfaces of the frame shaped body ( 2 ) and movable to directions along each of the respective surfaces, and tilting mechanisms for changing the pressing directions of the side surface cylinders ( 9 ).

1 . A body frame corrector comprising: 
 a frame-shaped body for installing a body frame therein,    a plurality of pressing devices for correcting the body frame, said pressing devices being disposed on a ceiling surface, a floor surface and inner side surfaces of the frame-shaped body and movable to directions along each of the respective surfaces, and    a tilting mechanism for changing pressing directions of the pressing devices, said tilting mechanism being disposed on the inner side surfaces of the frame-shaped body.    
     
     
         2 . The body frame corrector according to  claim 1 , wherein the tilting mechanism comprises: 
 a hinge member which moves up and down along a pillar which is mounted on a side of the frame-shaped body and movable in a horizontal direction,    a pressing device mounting member provided on the hinge member, and    a detachable fixing member to keep the pressing device mounting member in a predetermined posture.    
     
     
         3 . The body frame corrector according to  claim 1  further comprising a moving mechanism which moves the pressing device disposed on the ceiling surface of the frame-shaped body throughout an entire area of the ceiling surface.  
     
     
         4 . The body frame corrector according to  claim 3 , wherein said moving mechanism comprises: 
 a rail member disposed on the ceiling surface of the frame-shaped body,    a beam member disposed in a direction perpendicular to the rail member and movable along the rail member, and    a pressing device mounting member which is movable along the beam member.
