Title:
DRILLING ROBOT AND AUTOMATIC DRILL CHANGER THEREFOR
Document Type and Number:
Japanese Patent JP3235067
Kind Code:
B2
Abstract:
PURPOSE: To ensure a compact design and save installation space by mounting a female adapter on a robot spindle, connecting a collet to the adapter via the engagement of a coupling groove and a ball, and providing the adapter with a sleeve for mounting and demounting the collet.
CONSTITUTION: A drill device 22 mounted on the end of a drilling robot spindle is constituted of a drill 23, a chuck 24, a jacob collet 25, a female adapter 26 or the like. In addition, long engagement grooves 28a and 28b are formed on the external center surface of the jacob collet 25 at a phase difference of 180 degrees in parallel to the axial line thereof. Also, when the collet 25 is coupled into the cylindrical section 32 of the adapter 26, a ball 37 is coupled to the engagement grooves 28a and 28b. In this case, a sleeve 34 presses the ball 37 internally with the energizing force of a compression coil spring 35 and, therefore, the engagement of the collet 25 and adapter 26 is locked. When the sleeve 34 is moved against the force of the spring 35, the ball 37 is released from a pressing force, and the collet 25 can be demounted.
