US 12,611,741 B2 · System of and method for automated mounting/dismounting of a cutting insert on a tool body

Abstract

A system for automated mounting and dismounting of at least one cutting insert on a tool body with a screwing tool is provided. The cutting insert includes a top surface, a bottom surface, a circumferential side surface connecting the top and bottom surfaces, and a through hole extending from the top surface to the bottom surface for receiving the shaft of a fastening screw. A carrier device is arranged to pick up and release the cutting insert with the fastening screw. The carrier device has a body having a front surface, a rear surface, a circumferential side surface connecting the front and rear surfaces, and a channel extending from a front end opening in the front surface to a rear end opening in the rear surface. A method for automated mounting of a cutting insert with a fastening screw on a tool body is also provided.

Dependent claims

A system for automated mounting and dismounting of at least one cutting insert on a tool body with a screwing tool, the system comprising:

at least one fastening screw having a shaft and a head, the shaft having an end point opposite to the head;
at least one cutting insert including a top surface, a bottom surface, and a circumferential side surface connecting the top surface and the bottom surface, the at least one cutting insert further including a through hole having a longitudinal axis extending from the top surface to the bottom surface for receiving the shaft of the fastening screw;
and
a carrier device arranged to pick up and release the at least one cutting insert and therein placed fastening screw, the carrier device including a body having a front surface, a rear surface, and a circumferential side surface connecting the front surface and the rear surface, the carrier device including a channel having a longitudinal axis extending from a front end opening in the front surface to a rear end opening in the rear surface, wherein the channel has a length L.

A method for automated mounting of at least one cutting insert with a fastening screw on a tool body by a carrier device, wherein the fastening screw includes a shaft and a head, the shaft having an end point opposite to the head, and wherein the at least one cutting insert having a top surface, a bottom surface, and a circumferential side surface connecting the top surface and the bottom surface, the at least one cutting insert further including a through hole, having a longitudinal axis, extending from the top surface to the bottom surface for receiving the shaft of the fastening screw, and wherein the carrier device includes a body having a front surface, a rear surface, and a circumferential side surface connecting the front surface and the rear surface, and wherein the carrier device has a channel, having a longitudinal axis, extending from a front end opening in the front surface to a rear end opening in the rear surface, wherein the channel has a length L, the method comprising the steps of:

inserting (S1) the shaft of the fastening screw into the through hole from the top surface of the at least one cutting insert;
placing (S2) the front surface of the carrier device on top of the top surface of the at least one cutting insert so that the longitudinal axis of the channel coincides with the longitudinal axis of the through hole;
attaching (S3) the carrier device to the at least one cutting insert;
picking up (S4) the at least one cutting insert with the therein placed fastening screw using the carrier device;
placing (S5) the bottom surface of the at least one cutting insert in a mounting pocket on the tool body by moving the carrier device relative to the tool body;
inserting (S6) a screwing tool through the channel via the rear end opening onto the head of the fastening screw by moving the screwing tool relative to the tool body;
and
fastening (S7) the at least one cutting insert on the tool body by rotating the screwing tool.
