Abstract

An apparatus for mounting a coordinate positioning apparatus accessory, such as a tool setter, to the workpiece mounting surface of a coordinate positioning apparatus, the workpiece mounting surface having a slot formed in it. The apparatus includes an insert for inserting into the slot of the workpiece mounting surface, and a mount attachable to a coordinate positioning apparatus accessory. The insert includes structure to fix the insert within the slot; the insert is substantially contained within the slot when inserted therein. The mount includes at least one protruding member for engaging the insert when contained within the slot, thereby fixing the mount, and therefore any coordinate positioning apparatus accessory attached to the mount, to the workpiece mounting surface of the coordinate positioning apparatus.

Claims

1. An apparatus for mounting a coordinate positioning apparatus accessory to a workpiece mounting surface of a coordinate positioning apparatus, the workpiece mounting surface having a slot formed therein, the apparatus comprising:

an insert comprising means for fixing the insert within the slot; and

a mount attachable to the coordinate positioning apparatus accessory, the mount comprising at least one protruding member for engaging the insert when contained within the slot, thereby fixing the mount to the workpiece mounting surface of a coordinate positioning apparatus, wherein

the means for fixing the insert within the slot is configured to retain the insert fixed within the slot with the insert lying flush or sub-flush with the workpiece mounting surface, when the mount is detached from the insert.

2. The apparatus according to claim 1, wherein the coordinate positioning apparatus is a machine tool.

3. The apparatus according to claim 1, wherein the means for fixing the insert within the slot comprises an expandable member, such that the insert is held within the slot by friction.

4. The apparatus according to claim 1, wherein the means for fixing the insert within the slot comprises one or more screws.

5. The apparatus according to claim 1, wherein the means for fixing the insert within the slot comprises an adhesive.

6. The apparatus according to claim 1, wherein the means for fixing the insert within the slot comprise means for fixing the insert within a tee slot formed in the workpiece mounting surface.

7. The apparatus according to claim 1, wherein the means for fixing the insert within the slot comprises means for fixing the insert within a U-shaped slot formed in the workpiece mounting surface.

8. The apparatus according to claim 1, wherein the mount comprises a plurality of protruding members.

9. The apparatus according to claim 8, wherein the mount comprises two protruding members.

10. The apparatus according to claim 8, wherein at least one of the plurality of protruding members is moveable relative to the mount.

11. The apparatus according to claim 10, wherein the at least one protruding member moveable relative to the mount is a hand moveable member.

12. The apparatus according to claim 8, wherein at least one of the plurality of protruding members is fixed relative to the mount.

13. The apparatus according to claim 1, wherein the action of engaging the at least one protruding member of the mount with the insert urges the mount into contact with the workpiece mounting surface.

14. The apparatus according to claim 1, wherein the insert is a longitudinal insert having first and second ends.

15. The apparatus according to claim 14, wherein the insert comprises at least one receiving means for receiving the at least one protruding member of the mount.

16. The apparatus according to claim 15 wherein the insert comprises two receiving means, the first receiving means provided at the first end of the insert and the second receiving means provided at the second end of the insert.

17. The apparatus according to claim 15, wherein the at least one receiving means provides one point of contact.

18. The apparatus according to claim 15, wherein the at least one receiving means provides two points of contact.

19. The apparatus according to claim 1, wherein the action of engaging the at least one protruding member of the mount with the insert urges the at least one protruding member of the mount against at least one wall of the slot in which the insert is contained.

20. The apparatus according to claim 1 comprising a coordinate positioning apparatus accessory attached to the mount, wherein the coordinate positioning apparatus accessory comprises a tool-setter.

21. The apparatus according to claim 1 comprising a coordinate positioning apparatus accessory attached to the mount, wherein the coordinate positioning apparatus accessory comprises a measurement probe.

22. The apparatus according to claim 1, for mounting a coordinate positioning apparatus accessory to a workpiece mounting surface on a bed of a coordinate positioning apparatus.

23. The apparatus according to claim 1, for mounting a coordinate positioning apparatus accessory to a workpiece mounting surface on a pallet.

24. An insert comprising:

means for fixing the insert within a slot in a workpiece mounting surface of a coordinate positioning apparatus; and

means for engaging at least one protruding member of a mount, the protruding member being attachable to a coordinate positioning apparatus accessory when the insert is retained in the slot to thereby fix the mount to the insert, wherein

the means for fixing the insert within the slot is configured to retain the insert fixed within the slot with the insert lying flush or sub-flush with the workpiece mounting surface when the mount is detached from the insert.

25. The insert according to claim 24, wherein the coordinate positioning apparatus is a machine tool.

26. The insert according to claim 24, wherein the means for fixing the insert within the slot in the workpiece mounting surface of a coordinate positioning apparatus comprises an expandable member, such that the insert is fixed within the slot by friction.

27. The insert according to claim 24, wherein the means for fixing the insert within the slot comprises screws.

28. The insert according to claim 24, wherein the means for fixing the insert within the slot comprises glue.

29. An apparatus for mounting a coordinate positioning apparatus accessory to a workpiece mounting surface of a coordinate positioning apparatus, the workpiece mounting surface having a slot formed therein, the apparatus comprising:

an insert comprising a fixing device operable to retain the insert fixed within the slot; and

a mount attachable to the coordinate positioning apparatus accessory, the mount comprising at least one protruding member for engaging the insert when contained within the slot, thereby fixing the mount to the workpiece mounting surface of a coordinate positioning apparatus, wherein

the fixing device is configured to retain the insert fixed within the slot with the insert lying flush or sub-flush with the workpiece mounting surface when the mount is detached from the insert.
