Sensor module, machine element or tool element, and machine tool
View Patent ↗The invention relates to: sensor modules for e.g. a tool holder, wherein the sensor unit is integrated as a structural entity; tool or machine elements designed with such sensor modules; and a machining/machine tool comprising such a sensor module. The sensor modules have a sensor system for detecting system states or operating states which occur during the machining of a workpiece.
1. A sensor module for a machine tool or machining unit, comprising a sensor system for detecting system states or operating states which occur during the machining of a workpiece and having a data transmission device for transmitting measurement signals of the sensor system to an evaluation unit, wherein the sensor module, which is designed as a structural unit, is cartridge-shaped, and is configured to be inserted into a recess of a tool holder, or
of a tool body of a lathing or milling tool, or
of a tool of a forming technology, such as a roller, a deep-drawing tool or a punching tool.
2. The sensor module according to claim 1 , in which the sensor system, a sensor electronics, the data transmission device, and a power supply are integrated.
3. The sensor module according to claim 2 , wherein the cartridge-shaped sensor module has an outer shell which encases the sensor system, the sensor electronics, the transmission device, and the power supply.
4. The sensor module according to claim 3 , wherein the power supply is an accumulator.
5. The sensor module according to claim 1 , in which a channel is formed for conducting cooling lubricant from a mechanical interface to a clamping device.
6. The sensor module according to claim 5 , wherein the sensor system is at least partially arranged in a rotation axis and the channel is designed to be circumferential to the sensor system.
7. The sensor module according to claim 6 , wherein the channel is designed as two opposite channels arranged circumferentially to the sensor system.
8. The sensor module according to claim 7 , wherein the two opposite channels are arranged in an arc or an S shape.
9. The sensor module according to claim 7 , wherein the two opposite channels are symmetrical.
10. The sensor module according to claim 6 , wherein the channel is U shaped or double-S shaped.
11. The sensor module according to claim 5 , wherein the cartridge-shaped sensor module is equipped with a connection, which is in fluid connection with a tube containing a cooling lubricant.
12. The sensor module according to claim 1 , wherein the sensor module is configured to be inserted into the recess of:
the tool holder, or;
the tool body of the lathing or milling tool, or;
the tool of the forming technology, such as the roller, the deep-drawing tool or the punching tool.
13. The sensor module according to claim 1 , wherein the cartridge-shaped sensor module is provided with an index projection, which fits into a corresponding index clearance of the recess.
14. The sensor module according to claim 13 , wherein the index projection is positioned axially on a side of an exit terminal and is radially spaced to a center axis of the sensor module.
15. The sensor module according to claim 1 , wherein the cartridge-shaped sensor module is a closed structural unit with a closed surface.
16. The sensor module according to claim 1 , wherein an axial length of the cartridge-shaped sensor module is approximately same as a diameter of the cartridge-shaped sensor module.
17. The sensor module according to claim 1 , wherein a cavity is formed in the cartridge-shaped sensor module, in which the sensor system is positioned.
18. The sensor module according to claim 1 , wherein the sensor system is pre-assembled with the sensor module prior to being inserted into the recess.
19. The sensor module according to claim 1 , wherein the sensor module is configured to be exchangeable.
20. The sensor module according to claim 1 , wherein the sensor module is configured to be inserted into the recess in a form fit or force fit manner.
