- Micro-percussion marking tool machine tool comprising a marking tool and micro-percussion marking method
- the present invention relates to the field of devices and methods for marking the surface of an object by micro percussion.
- the marking can be carried out by micro percussion, by means of a tool comprising a point which is driven in an alternating translational movement and which strikes the surface to be marked.
- the marking of the object is thus achieved by deformation of its surface following micro percussions.
- a known system for producing such a marking is an electromagnetic micro-percussion marking tool.
- the marking is done manually by an operator, outside of the machining cycles, thus extending the overall processing time.
- the known marking tools often require a specific installation which also increases the time for marking and for complete processing of the manufactured part.
- An object of the present invention is to provide a marking tool which makes it possible to reduce the time required for the marking.
- micro-percussion marking tool for carrying out a marking on a surface of an object (or part), comprising micro-percussion marking means comprising a marking member.
- the marking tool of the invention further comprises mechanical coupling means for mechanically coupling the marking means to a machine tool.
- the marking tool of the invention further comprises a battery and a sensor capable of communicating with an antenna of the machine tool. It is then possible to have a marking tool having an integrated power supply for the marking means, and to control the marking means remotely and without a wired connection from a control unit of a machine tool.
- the invention therefore makes it possible to have a micro-percussion marking tool which can be mounted as a spindle on a machine tool (or machining machine), for example with numerical control, and which can be controlled (in position and content) from the machine tool control (for example its numerical control).
- a marking during the machining cycle of a part. This helps to reduce the time required for marking.
- the marking is not done outside the machine tool.
- These different steps can be done with the machining machine.
- the time required for marking is therefore reduced.
- the marking solution is therefore more efficient.
- the invention also enables automation of the marking process, reduces the risk of errors and is particularly compact.
- the marking precision can be great with the marking tool of the invention because one can take advantage of the precision of CNC machining machines.
- micro-percussion marking means could be called a micro-percussion marking system or unit, without altering the invention and its scope.
- These marking means comprise, for example, an electromagnetic micro percussion device as described in EP2875173 for imparting the micro percussion movement to the marking member.
- the latter is preferably a point.
- a machine tool has a spindle.
- a spindle is an element known to a person skilled in the art, relating to the part connected to the motor of the machine tool and being able to receive various rotating tools to carry out machining.
- the mechanical coupling means of the marking of the invention make it possible to fix the marking means to such a pin.
- the mechanical coupling means comprise a standard interface capable of taking various tool attachments such as for example ISO, Capto, HSK.
- the dot peen marking tool is electromagnetic
- the battery is configured to supply electrical energy to the electromagnetic marking means.
- the marking tool of the invention further comprises means for moving the marking member to at least partially sweep the surface of the object to be marked.
- This preferred embodiment corresponds for example to a case where a marking gun is coupled to the machine tool to carry out the marking.
- a marking gun generally comprises means for moving the marking member so as to sweep the surface to be marked.
- the inventors also propose a machine tool comprising:
- control unit for controlling the marking means, and in particular a movement of said marking member
- Such a machine tool has all the advantages of the marking tool of the invention. In particular, it makes it possible to reduce the time required for marking.
- the machine tool is a numerically controlled machine where the control unit is a numerical control unit.
- the control unit is preferably able to control them.
- the machine tool of the invention comprises means for setting in motion to move the marking member to at least partially sweep the surface of the object to be marked, said control unit being able to control said means for setting in motion.
- These movement means are distinct from the movement means described above and forming part of the marking tool according to a preferred variant.
- the machine tool by means of the movement means, allows the marking member to be moved until the entire marking is carried out, point by point. There is then no need for other means of movement which would be integrated into the marking tool, as would be the case if a marking gun were used.
- the machine tool marking tool comprises movement means which can be used in combination with the means for setting the machine tool in motion.
- movement means which can be used in combination with the means for setting the machine tool in motion.
- the means of movement it is possible to use the means of movement to achieve large movements of the marking member, while the means of movement are used for smaller movements, with better resolution and better control.
- the inventors propose an assembly comprising:
- the storage suitable for receiving the marking tool, the storage comprising a battery recharging seat.
- the inventors propose a method of micro percussion marking of a surface of an object, comprising the following steps:
- an electromagnetic dot peen marking tool comprising
- a battery for supplying electrical energy to the electromagnetic micro-percussion marking means
- Step iv for example comprises a sub-step of positioning the marking member at the center of the marking and / or at the height of a first point to be marked.
- the marking tool comprises means for moving the marking member and step vi comprises controlling said means for moving through the control unit.
- step vi comprises controlling said means for moving through the control unit.
