Abstract

The disclosure is based on an electronic module for an insert tool, in particular a drill bit or a chisel, including at least one electronic device for processing and/or sensing insert-tool-specific characteristics, including at least one holding device for releasably holding the electronic device on the insert tool. The holding device having at least one insert-tool interface having at least one contact surface that, when the holding device is arranged on the insert tool, is in contact, in particular in direct contact, with the insert tool, and including at least one damping unit for damping vibrations acting on the electronic device. The damping unit at least partially constitutes the insert-tool interface.

First claim

What is claimed is:

1. An electronic module for an insert tool, comprising:
at least one electronic device configured to at least one of process and sense insert-tool-specific characteristics; and
at least one holding device configured to releasably hold the at least one electronic device on the insert tool, the at least one holding device including
at least one insert-tool interface including at least one contact surface that, when
the at least one holding device has been arranged on the insert tool, is in direct contact with the insert tool, and
at least one damping unit configured to damp vibrations acting on the at least one electronic device, wherein the at least one damping unit at least partially constitutes the at least one insert-tool interface.

2. The electronic module according to claim 1 , wherein the at least one damping unit has at least one damping element, designed in the manner of a circular ring segment which constitutes the at least one contact surface of the at least one insert-tool interface.

3. The electronic module according to claim 1 , wherein:
the at least one holding device comprises a housing in which the electronic device is arranged; and
the at least one damping element of the at least one damping unit constitutes the at least one contact surface of the insert-tool interface, and is arranged on a side of the housing that faces toward the insert tool when the at least one holding device is arranged on the insert tool.

4. The electronic module according claim 1 , wherein:
the at least one damping unit at least partially surrounds a receiving region for the insert tool; and
the at least one holding device and the at least one damping unit, at least in an operating state, are configured to at least one of
have a common center of mass, and
have a central axis of the receiving region intersect a center of mass of the holding device and of the damping unit, at least as viewed in a plane perpendicular to the central axis.

5. The electronic module according to claim 1 , wherein the at least one holding device comprises at least one holding unit which is designed for at least one of attaching and detaching the insert tool to/from the at least one insert-tool interface without use of tools, in a receiving region for the insert tool that is at least partially delimited by the at least one damping unit.

6. The electronic module according to claim 1 , wherein the at least one holding device comprises at least one holding unit realized as a bayonet lock designed for releasably attaching the insert tool to the at least one insert-tool interface in a receiving region for the insert tool that is at least partially delimited by the at least one damping unit.

7. The electronic module according to claim 6 , wherein the bayonet lock comprises at least one metallic locking ring.

8. The electronic module according to claim 1 , wherein the at least one damping unit comprises at least one damping element realized as a shrink-on sleeve.

9. The electronic module according to claim 1 , wherein the at least one damping unit comprises at least one damping element realized as an O-ring.

10. The electronic module according to claim 1 , wherein the at least one damping unit at least partially constitutes the insert-tool interface in such a manner that the at least one damping unit, when the insert tool is arranged at the insert-tool interface, is designed at least to damp vibrations, acting on the electronic device, caused by impacts or shocks of the insert tool acting along an axis of rotation of the insert tool.

11. An insert tool system comprising:
at least one insert tool; and
at least the electronic module according to claim 1 .

12. The insert tool system according to claim 11 , wherein the at least one damping unit, when the electronic module is arranged on the insert tool, bears directly against an external surface of the insert tool.

13. The insert tool system according to claim 12 , wherein the insert tool, at least when the electronic module is arranged on the insert tool, is at least substantially completely enclosed by the at least one damping unit and the holding device, at least as viewed along a circumferential direction of the insert tool.
