Abstract

The adjustment head is intended for use in the working space of a CNC machine which has a base station set up and intended for the exchange of information with a measuring probe or bore measuring mandrel, which base station is connected to a control of the CNC machine, and comprises a first function module and a second function module, wherein the first function module is divided into a power supply module and a data transmission module, wherein the second function module comprises a machining module for receiving at least one tool, wherein the machining module comprises a tool adjustment device for adjustment the tool in a radial and/or an axial direction and/or in an angular orientation of the tool based on specifications of the control, and wherein the power supply module supplies components of the adjustment head, including the data transmission module and the tool adjustment device, with electrical power, and wherein the data transmission module is arranged and intended for exchanging information concerning at least the adjustment of tool accommodated in the adjustment head with the base station of the measuring probe or bore gauge in the working space of the CNC machine.

Claims (18)

1 . An adjustment head intended and arranged for use in a working space of a CNC machine having a base station arranged and intended for information exchange with a measuring probe or bore gauge connected to a control of the CNC machine, the adjustment head comprising:

a first function module and a second function module, the first function module being divided into a power supply module and a data transmission module, wherein the power supply module and the data transmission module have an integrated coolant duct for passing coolant to at least one machining point of the machining module,

the second function module comprising, a machining module for receiving at least one tool, the machining module comprising a tool adjustment device for adjustment the tool or its cutting edge/s in a radial and/or an axial direction and/or in an angular orientation of the tool-based on instructions from the controller,

wherein the first function module includes a first section of the integrated coolant duct and the second function module includes a second section of the integrated coolant duct,

wherein the power supply module supplies electrical power to components of the adjustment head, including the data transmission module and the tool adjustment device, and

wherein the data transmission module is arranged and intended for exchanging information concerning at least the adjustment of the tool accommodated in the adjustment head with the base station of the measuring probe or bore gauge in the working space of the CNC machine.

2 . The adjustment head according to claim 1 , wherein the data transmission module of the adjustment head and the base station are arranged and intended to exchange the information concerning at least the adjustment of the tool received in the adjustment head via a wireless bidirectional radio interface or a wireless bidirectional infrared interface.

3 . The adjustment head according to claim 1 further comprising an integrated displacement measurement module for detecting the displacement of the tool in the machining module.

4 . The adjustment head according to claim 1 , wherein the machining module is adapted to receive a spindle tool with adjustable adjustment of the tool or its cutting edge/s, which does not allow any change during machining operation, or the machining module allows for an adjustment of the tool or its cutting edge/s during machining, or the machining module is adapted to receive a reaming tool having a plurality of cutting edges, allowing a finely adjustable adjustment of the tool or its cutting edge/s during machining, or the machining module is adapted to receive a honing tool and is adapted to adjust the honing tool during machining, the machining module is adapted to receive a honing tool and is adapted to adjust honing stones of the honing tool during machining and to signal data on a current diameter of the honing tool via the data transmission module to the control of the CNC machine so as to trigger termination of a honing process by the control when a programmed production dimension is reached.

5 . The adjustment head according to claim 1 , in which an adjustment of the tool or its cutting edge/s in the machining module is to be effected electrically by an electric motor or a piezo drive, or an adjustment of the tool or its cutting edge/s in the machining module is to be effected hydraulically by means of a pressurised cooling fluid, wherein an adjustment of the tool or its cutting edge/s is to be effected by the fluid.

6 . The adjustment head according to claim 1 , wherein in a variant of hydraulic adjustment of the tool or its cutting edge/s data transmitted from the control of the CNC machine to the data transmission module serves to control a fluid valve in order to effect, together with an integrated displacement measurement module, an adjustment of the tool or its cutting edge/s in accordance with the data from the control of the CNC machine during the cutting operation.

7 . The adjustment head according to claim 1 , wherein the data transmission module is arranged and intended to signal raw data signals or process status signals from the adjustment head to the control of the CNC machine.

8 . The adjustment head according to claim 1 , in which at least one sensor is provided in the machining module, adapted and intended to detect operating parameters of one or more cutting edges of a tool located in the machining module via temperature, vibration, tool cutting condition or cutting force of the tool or its cutting edge/s, and to signal them via the data transmission module as a raw data signal or as a process status signal to the control of the CNC machine.

9 . The adjustment head according to claim 1 , wherein a turbine is provided in the power supply module, which is to be set in rotation by means of a pressurised fluid, wherein the turbine is operatively coupled to a generator, which supplies converted energy to a battery and/or capacitor for intermediate storage.

10 . The adjustment head according to claim 1 , in which cumulatively or alternatively to the data transmission module, an interface module is provided which is intended and set up to detect and process one or more manual inputs by means of a contacting or non-contacting external transmitter in the form of an actuating pin, a light or ultra sound source, a permanent or electromagnet, or the like, in order to effect a signalling to the machining module in the sense of a fine adjustment of the tool or its cutting edge/s, the assumption of a retracted or extended end position, a predefined nominal position, or the like.

11 . The adjustment head according to claim 1 , in which an interface module has an optical, acoustic and/or haptic output unit for feedback of an input that has been made, and is intended and set up for triggering different positioning sequences of a tool located in the processing module or of its cutting edge/s depending on the respective input by corresponding control of an actuator in the form of an electric motor, piezo drive, fluid valve or the like to trigger an adjustment of the located tool or its cutting edge/s.

12 . The adjustment head according to claim 1 , wherein the data transmission module and an interface module are arranged and intended to receive an activation and/or message of the adjustment head for selectively effecting a manual adjustment or an adjustment predetermined via a wireless data link of a tool or its cutting edge/s located in the machining module.

13 . The adjustment head according to claim 1 , wherein the second function module can be detached from the first function module and replaced with a different machining module.
