DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a car body rectifying means comprising a frame, a rectifying table disposed to be vertically movable in relation thereto, and attachments or equivalent on the rectifying table in which the vehicle is fixable.
Such car body rectifying means are known in the art in which the car is driven onto the rectifying table and clamped with skirt attachments, and lifted to desired height. In rectifying means of prior art, the rectifying work has been arranged to take place with the aid of rectifying tools provided on vertical supporting arms. By moving the car, fixed with the skirt attachments of the rectifying table in the vertical direction, such vertical movement has been utilized in the rectifying work itself. It has been possible to move the vertical supporting arms, as is disclosed in the assignee's earlier Finnish Pat. Nos. 59348 and 53930, by moving telescopic beam arrays. In apparatus designs of prior art, rectifying operations have been easy to accomplish specifically in the case of a car's body structures. It may be held forth as a drawback of existing apparatus designs that the rectifying is substantially confined to the body structures of the car. Rectification of the chassis beams themselves cannot be satisfactorily performed with apparatus designs of prior art.
Such rectifying means are also known in the art which have jigs for various parts of the car chassis and in which the chassis structure of the car is not altered when rectifying action is directed on the remaining part of the body. These jigs are meant to maintain in correct position various parts of the car; they are not intended to carry out any rectifying work.
SUMMARY OF THE INVENTION
The object of the present invention is a car body rectifying means by which rectification of the car body's frame beams can be conveniently performed and with the aid of which furthermore the rectifying work on the upper body structures of the car body can be carried out. It is a further object of the invention to provide car body rectifying means which enable performing of the rectifying work with simple, and therefore advantageous, apparatus arrangements.
The means of the invention is mainly characterized in that to a frame component which is stationary in relation to the rectifying table of the rectifying means or to a frame component therewith associated and moving along therewith, or to the rectifying table, has been attached, movably in a horizontal plane, a rectifying unit, this rectifying unit comprising a frame consisting of a first frame portion and a second frame portion which has been disposed to be movable in relation to said first frame portion, and said rectifying unit comprising implements for performing rectifying work both on the chassis beams of the vehicle and on the body structures themselves, the rectifying force being directable to act on the object under rectification in horizontal as well as vertical direction.
The other characteristic features of the invention described below.
The means of the invention operates like a jig, that is, it holds the object in place, but it also executes rectifying movements in every direction, meaning that it takes a hold on the damaged part and moves it into its proper position, where it can be locked, whereafter the rectifying work may proceed with reference to another object. In the means of the invention, many of the rectifying movements can be produced using one single cylinder, by the aid of which the rectifying head performing the rectifying work can be made to move in the longitudinal and transversal directions and, furthermore, from the rectifying table rectifying forces are derived for the chain of the rectifying jib. The design of the invention is advantageous and efficient.
Numerous advantages are gained with the apparatus design of the invention. The rectifying unit of the invention is easy to attach and to detach, whereby it becomes possible to move the rectifying unit from one to the other of the rectifying means. The rectifying
