Tool Interface Device, Insert Tool Comprising a Tool Interface Device, and Machine Tool System Comprising an Insert Tool and a Machine Tool

Abstract

The disclosure relates to a tool interface device for an insertion tool for connecting the insertion tool to a tool holder of a machine tool, having at least one connection interface for connecting to a quick-release device of the tool holder, wherein the connection interface has a recess at least partially bounded by a boundary edge of the connection interface, and wherein the connection interface comprises at least one securing element at least partially forming the boundary edge. It is proposed that the connection interface comprises at least one tool mounting coding element spaced apart from the at least one securing element and at least partially forming the boundary edge and provided for interacting with at least one mounting coding element of the tool holder in a state of the connection interface arranged on the tool holder.

1 . A tool interface device in the form of insertion tool hub, for an insertion tool for connecting the insertion tool to a tool holder of a portable machine tool, comprising:
 at least one connection interface for a frictional and/or positively locking connection to a quick-release device of the tool holder,   
       wherein
 the connection interface has a recess bounded at least partially by a boundary edge of the connection interface, 
 the connection interface has a securing element in the form of a wing clamp configured to be axially secured on the quick-release device and configured to transmit a torque in a state of the connection interface on the quick-release device, which at least partially forms the boundary edge, and 
 the connection interface comprises at least one tool mounting coding element spaced apart from the at least one securing element, which at least partially forms the boundary edge and is provided for interacting with at least one mounting coding element of the tool holder in a state of the connection interface arranged on the tool holder. 
 
     
     
         2 . The tool interface device according to  claim 1 , wherein:
 the connection interface comprises a further securing element in the form of a further wing clamp configured to be axially secured to the quick-release device and configured to transmit a torque in a state of the connection interface arranged on the quick-release device, said further securing element at least partially forming the boundary edge, and   the at least one tool mounting coding element is arranged along the boundary edge in a central region between the securing element and the further securing element.   
     
     
         3 . The tool interface device according to  claim 1 , wherein the tool mounting coding element has a recess in the boundary edge. 
     
     
         4 . The tool interface device according to  claim 1 , wherein the tool mounting coding element comprises a protrusion on the boundary edge. 
     
     
         5 . The tool interface device according to  claim 1 , wherein the tool mounting coding element comprises a protrusion on the boundary edge having an axially protruding component. 
     
     
         6 . The tool interface device according to  claim 5 , wherein:
 a surface surrounds the connection interface, a main extension plane of which is spaced apart from a main extension plane of the securing element; and,   the axially projecting component of the protrusion is arranged at least substantially entirely between the main extension plane of the surface surrounding the connection interface and the main extension plane of the securing element.   
     
     
         7 . The tool interface device according to  claim 1 , wherein the at least one tool mounting coding element has a maximum extent along a radial axis that is at most a value of a maximum height of the securing element along a radial axis. 
     
     
         8 . An insertion tool having a tool interface device according to  claim 1 . 
     
     
         9 . A machine tool system having at least one insertion tool according to  claim 8  and having at least one machine tool having at least one tool holder having a quick-release device on which the insertion tool is arranged. 
     
     
         10 . The machine tool system according to  claim 9 , wherein:
 the quick-release device and the connection interface of the tool interface device form a bayonet lock; and   the tool mounting coding element is spaced apart from the securing element and interacts with the mounting coding element of the quick-release device in a state of the connection interface mounted on the quick-release device.
