Description
- The present invention relates to an automobile body and chassis straightening apparatus for straightening and aligning automobile frames and bodies. Generally, when correcting body or chassis damage, a car is put between the arms of a rigid stationary frame and secured thereto by chains wrapped around some portion of the car. The dents are then pulled out by a frame puller device that either uses hydraulic powered arms which hook on to the dented area or that uses chains operated by manual or motor-driven winches.
- The use of turntables on which work pieces are mounted for deformation was disclosed in U.S. Patent 94,745. The particular design shown therein deals with the formation of cartridge shells. U.S. Patent 2,676,640 discloses an apparatus for straightening the inner covers used in box annealing furnaces. The device has a powered turntable upon which the steel cylinder is placed endwise and rotated in order to bring the dents opposite to the straightening dies.
- A number of patents have been addressed to frames that are designed to facilitate the pulling and pushing operations on the vehicle body. U.S. Patent 3,777,541 discloses the use of a horizontally disposed frame, adapted to support a damaged vehicle, that is mounted on casters so that it can be positioned below the automobile. The pulling arrangement that is used with this frame is rigidly mounted to the frame. U.S. Patent 4,023,394 discloses a frame for the repair of damaged vehicle body structure of the type in which the frame is secured to the vehicle body or frame and supports force-applying apparatus and measuring apparatus. The frame is assembled under the car and can also be mounted on a forklift truck for moving from place to place. There is no relative pivoting between the pulling devices and the frame. U.S. Patent 4,289,016 discloses a frame with hydraulic grippers and body frame puller which attach to the automobile.- Again, there is no relative pivoting between the pulling device and the frame.
- U.S. Patent 4,313,335 and Canadian Patent 1,065,748 disclose the use of a fixed frame with pulling devices mounted to the frame and movable about the car in order to give the desired pulling angles. However, the frames do not pivot with respect to the pulling devices; rather, the pulling devices are movable about the frame and lockable in place for the pulling operation.
- The present invention relates to an automobile body and frame straightening apparatus comprising stationary support means, a frame for supporting an automobile, the frame being capable of rotation, a plurality of automobile body frame attachment means to secure the automobile against movements relative thereto, and an automobile body and frame puller for straightening the body and frame of the automobile. The frame and car supported thereon may be rotated by means of a hydraulic cylinder device extending in a connected relationship between the stationary support means and the frame. The frame puller remains stationary relative to the support means. The puller exerts a substantially horizontal pulling force on the dented metal sheet of the automobile body or frame.
-
- Figure 1 shows the car that is to be repaired mounted on the rotating frame and being operated on by the hydraulic pulling device.
- Figure 2 shows a view as seen from above the automobile mounted on the rotating frame, and provides a view through the automobile.
- Figure 3 again shows a view as seen from above the automobile mounted on the rotating frame, and provides a view through the automobile.

Rod 26 passes through interim metal plate 27 which is rigidly secured tobeams 11 and 12 ofsupport 10. - A plurality of
ball bearings 30 are located betweenplate 25 and plate 27 in order to permitplate 25 to rotate more easily relative to plate 27.Metal plate 29, which is rigidly connected byrod 26 tometal plate 25, has formed therein in a circular pattern a plurality ofholes 31.Attachment piston 32 is capable of securely engaging stud in anyhole 31. Piston 32 extends fromhydraulic cylinder device 33 which is connected bypivot 34 to beam 11. By appropriately engaging a stud inhole 31 withattachment piston 32 and extending or retractingpiston 32 usinghydraulic cylinder device 33,metal plate 29 is caused to rotate by small increments in the direction ofarrow 100 about the axis of rotation ofrod 26 shown as 1-1. This in turn causes connectedrod 26 and thereto connectedplate 25 to rotate in the same direction and by the same amount.Beams plate 25, are similarly rotated. Thus rotation ofplate 29 causesframe 20 to rotate, permittingcar 1 to be turned to any position relative to the original position ofcar 1 with respect to the hydraulic pulling assembly. A number ofholes 31 are used in order to make possible fine adjustments in the position of the car relative to the puller. -
