Abstract

An interface apparatus for releasably attaching a primary part of a linear motor to a carriage includes an attachment module configured to attach the primary part of the linear motor to the interface apparatus. At least one insertion portion is configured to permit insertion into a holding portion of the carriage along an axial direction of the linear motor. At least one blocking apparatus is configured to releasably block the at least one insertion portion in the holding portion of the carriage.

First claim

What is claimed is:

1. An interface apparatus for releasably attaching a primary part of a linear motor to a carriage, the interface apparatus comprising:
an attachment module configured to attach the primary part of the linear motor to the interface apparatus;
at least one insertion portion configured to permit insertion into a holding portion of the carriage along an axial direction of the linear motor; and
at least one blocking apparatus configured to releasably block the at least one insertion portion in the holding portion of the carriage.

2. The interface apparatus as recited in claim 1 , wherein the blocking apparatus includes at least one of a wedge, a spring, a magnet and a hydraulic system.

3. The interface apparatus as recited in claim 2 , wherein the blocking apparatus is configured to block the insertion portion in the holding portion of the carriage by clamping.

4. The interface apparatus as recited in claim 3 , wherein the blocking apparatus includes at least one wedge and at least one screw, which are movably disposed relative to the interface apparatus, in such a way that the wedge is movable in response to actuation of the screw relative to the interface apparatus.

5. The interface apparatus as recited in claim 4 , wherein the wedge has at least one groove, and wherein the screw has at least one ridge which engages in the groove of the wedge.

6. The interface apparatus as recited in claim 4 , wherein the wedge is movable in response to actuation of the screw parallel to the axial direction and is configured to effect a clamping of the insertion portion in a second direction that differs from the axial direction.

7. The interface apparatus as recited in claim 6 , wherein the blocking apparatus further comprises at least one clamping element that is movably disposed relative to the interface apparatus parallel to the second direction, the wedge and the clamping element being configured to permit movement of the clamping element in response to movement of the wedge.

8. The interface apparatus as recited in claim 1 , wherein two insertion portions are disposed on opposing sides of the attachment module, against each of which a respective blocking apparatus is positioned.

9. The interface apparatus as recited in claim 1 , further comprising at least one cooling channel for cooling the primary part of the linear motor.

10. A carriage for use with a linear motor, the carriage comprising the holding portion which is configured to accommodate the at least one insertion portion of the interface apparatus as recited in claim 1 .

11. A carriage system comprising the interface apparatus as recited in claim 1 , and a carriage, wherein the holding portion of the carriage is configured to accommodate the at least one insertion portion of the interface apparatus along the axial direction.

12. A linear motor system, comprising:
the interface apparatus as recited in claim 1 ,
the linear motor having the primary part and a secondary part, the primary part of the linear motor being attachable to the attachment module of the interface apparatus, and
a carriage having at least one holding portion configured to accommodate the at least one insertion portion of the interface apparatus along the axial direction.

13. A method for releasably attaching a primary part of a linear motor to a carriage, the method comprising:
providing a linear motor system, which includes:
an interface apparatus having an attachment module including at least one insertion portion and at least one blocking apparatus;
the linear motor having the primary part and a secondary part, the primary part of the linear motor being attached to the attachment module of the interface apparatus and to a carriage having at least one holding portion;

inserting the at least one insertion portion of the interface apparatus into the at least one holding portion of the carriage along an axial direction of the linear motor; and
actuating the at least one blocking apparatus in order to releasably block the at least one insertion portion in the at least one holding portion.
