Abstract
A device for alignment of a vehicle body and a method in the work of alignment of a vehicle body. The device includes an alignment table to which the vehicle is attached by skirt clamps, the vehicle being fixed from skirt plates to the skirt clamps and through the skirt clamps to the alignment table during alignment work. Each skirt clamp has a support arm which is positionable in relation to, and separated from, the skirt clamp and which support arm can be coupled with the skirt clamp by a fastening member. The support arm is also connected with the constructions of the vehicle directly or through intermediate parts such that damage to the skirt beam is prevented by the support arm during the alignment work as the support force of the support arm is received by the skirt clamps.
Claims21
A device for alignment of a vehicle having skirt beams, comprising
- an alignment table,
- skirt clamps arranged on said alignment table for attaching the skirt beams of the vehicle to said alignment table, each of said skirt clamps comprising a first body part having a first jaw and a second body part having a second jaw, and displacement means for moving said first and second jaws relative to one another to grasp a first support skirt beam of the vehicle,
- a support arm,
- fastening means for detachably connecting said support arm to said first body part of at least one of said skirt clamps such that said support arm is movable relative to said at least one of said skirt clamps, and
- coupling means for coupling said support arm to a second support region of the vehicle.
- wherein said fastening means comprise
- a back-up recess arranged in said first body part,
- a back-up part having a recess arranged in connection with or in the direct vicinity of said back-up recess in said first body part, and
- pressing means for pressing said back-up part against said support arm while said support arm is in a position between said back-up recess in said first body part and said recess of said back-up part.

A method for supporting a vehicle body during alignment of the vehicle body on an alignment table, wherein the vehicle has skirt beams each having a lower joint and an upper joint, comprising the steps of:
- grasping the lower joint of a skirt beam by means of first skirt clamps of respective skirt fastenings coupled to the alignment table,
- movably mounting a first end of an elongate support arm in connection with each of the skirt fastenings,
- mounting a second skirt clamp to a second end of each of the support arms such that each of the second skirt clamps, is coupled to a respective one of the first skirt clamps and
- grasping the upper joint of the skirt beam by means of the second skirt clamps by adjusting the position of the support arms with respect to a respective one of the skirt fastenings until the respective second skirt clamp engages and is clampable to the upper joint of the skirt beam.
