发明名称 Method for straightening an automotive bodyshell and straightening apparatus for implementing the same
摘要 The present invention concerns a method for straightening the bodyshell of an automotive vehicle in a straightening jig, said method comprising fixing the bodyshell (1) to a straightening jig, moving a straightening boom (2) incorporated in the straightening jig to a proper position relative to the bodyshell, fixing at least two clamp tools (3) to the automotive bodyshell and to a pulling tool member (4) which is passed via a backing member (7) connected to a power actuator (6). Furthermore, the invention concerns a straightening apparatus comprising a straightening boom (2), a clamp tool (3) and a pulling tool member (4). Conventional apparatuses fail to provide equal force at the different points being pulled and are not capable of stopping the movement of a pulling tool member in a selected direction. In the method according to the invention, the pulling tool member (4) is adjusted to reach to the automotive bodyshell (1) from a desired angle with the help of guidance elements (5) attachable to the straightening boom at a desired height, and the pulling tool member (4) is locked in place by means of a locking device (8), while the pulling operation is continued by means of that section of the pulling tool member remaining on the opposite side.
