Abstract

A device for determining orientation of an object, including a measurement body, which reflects electromagnetic radiation and can be brought into physical contact with a surface of the object to determine the orientation. The device includes: a measurement carriage movable along the object during the determination of the orientation and which has a sliding surface that can be brought into physical contact with the object; a retaining unit which retains the measurement body and is connected to the measurement carriage so as to be pivotable between a maximal position, in which the measurement body protrudes beyond the sliding surface on the object side, and a minimal position, in which the measurement body does not protrude beyond the sliding surface on the object side; and a restoring device that applies a force to the retaining unit toward the maximal position.

First claim

The invention claimed is:

1. A device for determining an alignment of at least one object, comprising:
at least one measuring body that reflects electromagnetic radiation and is bringable into physical contact with a surface of the at least one object to determine the alignment;
at least one measuring carriage that is movable along the at least one object during the determination of the alignment and has a sliding surface physically contactable contact with the at least one object;
at least one holding unit that holds the at least one measuring body and is connected to the at least one measuring carriage so as to be pivotable between a maximum position, in which the at least one measuring body at least partially protrudes beyond the sliding surface on an object side, and a minimum position, in which the at least one measuring body does not protrude beyond the sliding surface on the object side; and
at least one restoring device configured to apply a force to the at least one holding unit in a direction of the maximum position.

2. The device according to claim 1 , wherein the at least one measuring carriage comprises at least two skids that are arranged parallel to one another and at a distance from one another and define the sliding surface, and at least one crosspiece that connects the at least two skids rigidly to one another and is aligned transversely in relation to the at least two skids, the at least one holding unit being connected to the at least one measuring carriage pivotably about a pivot axis aligned transversely in relation to the at least two skids and parallel to the at least one crosspiece.

3. The device according to claim 1 , wherein at least one magnet is arranged on the at least one measuring carriage.

4. The device according to claim 1 , further comprising at least one movement device that is connected to the at least one measuring carriage, the at least one movement device being configured to move the at least one measuring carriage vertically along the at least one object during the determination of the alignment.

5. The device according to claim 1 , wherein the device has frictional connections.

6. A system for determining an alignment of at least one object, comprising: at least one laser tracker; at least one evaluation device that evaluates measuring signals of the at least one laser tracker; and a device according to claim 1 , the at least one laser tracker being configured to follow the at least one measuring body during movement of the at least one measuring body along the surface of the at least one object.

7. A method for relatively aligning rollers of a segment of a roller guide, comprising the steps of:
determining the relative alignment of the rollers by using a system according to claim 6 ; and
aligning the rollers taking into account a result of the determination carried out with the system.
