Machine for automatically regulating and measuring the length of extension and the diameter of a tool

Machine for automatically adjusting and measuring the length of extension of a tool 2 mounted in a conical mandrel 3 capable of cooperating with a receiving cone 7 of said machine, said conical mandrel 3 being provided with an opening axial tap 5 adapted to receive said tool 2, and comprising a means 9 for tightening said tool 2, as well as a means 17 for adjusting said tool 2 housed in said axial tap 5, said tool 2 coming into contact with said adjustment means 17, said machine comprising a frame 25 and two carriages 26 and 27 movably mounted on said frame 25, and capable of moving respectively parallel and transversely to the axis of said tool 2, characterized in that the first of said carriages 26 comprises said receiving cone 7 receiving said conical mandrel 3 provided with said tool 2, a first control means 31, 32 acting on said tightening means 9, and a second control means 35, 39 acting on said adjustment means 17, in that the second of said carriages 27 comprises a means 48 for detecting and measuring said tool 2 making it possible, when said tool 2 comes into contact with said detection and measuring means 48, to measure the length of extension of said tool 2 with respect to said mandrel 3, means 48 for detecting and measuring said tool 2 being disposed on said second carriage 27, being constituted of a measuring sensor 48 against which the front face 22 of said tool 2 is capable of being applied a retractable sensor cover 49 being mounted on said measuring sensor 48, the placing of said tool 2 in contact against said detection and measuring means 48 being effected by said adjustment means 17, and in that said machine comprises

• a programmer 57 in which are programmed the operations of adjustment and measurement carried out in accordance with an automatic cycle established previously,
• a control keyboard 55 for the introduction of specific data in said programmer 57, and
• a display means 60 receiving a signal 63 from said detection and measuring means 48, corresponding to a magnitude representative of the length of extension of said tool 2, and indicating said extension length.
