The drill bit, the chamfering tool and the countersink are integrated into a set of tool, and the chamfering tool and the countersink are distributed in a centrosymmetric mode (the distance between the chamfering tool and the countersink is 180 degrees). During drilling, the chamfering cutter and the countersink gradually contact the edge of the drilled hole along with the penetration of the drill bit, and the chamfering surface and the countersink surface are simultaneously processed, so that the workpiece is drilled and countersunk for one-step forming.
The cutter bar on be equipped with the mounting groove of chamfer sword and countersink looks adaptation, chamfer sword and countersink are arranged in the mounting groove and are fastened through cutter set screw. By fixing the chamfering tool and the countersink on the tool bar in the mode, the structure is simple, the fixation is firm, and the replacement is convenient
Preferably, the chamfering tool is in a regular triangle shape and is provided with three chamfering tool cutting edges. After any cutting edge is worn, the cutting edge can be dismounted and mounted after rotating by a corresponding angle (120 degrees), and other cutting edges are used.
Preferably, the countersink is square and is provided with four countersink cutting edges. After any cutting edge is worn, the cutting edge can be detached and rotated by a corresponding angle (90 degrees) and then installed, and other cutting edges are used.
Preferably, the corner of the mounting groove is provided with a stress relief hole, so that the stress of the corner is relieved, and the overall strength is improved.
Compared with the prior art, the utility model beneficial effect who has is:
bore combination tool of falling countersink owing to adopt the structure of boring the countersink combination, the drill bit passes through drill bit holding screw and cutter arbor fastening together, countersink and chamfer pass through cutter set screw and cutter arbor fastening together, drill bit, countersink, chamfer sword are split type structure with the cutter arbor, the independence is strong, can change alone after wearing and tearing or destruction, has reduced the cutter cost. The independence is strong, does not influence each other, dismantles and installs, and convenient, swift has improved work efficiency.
The countersink and the chamfer are provided with a plurality of cutting edges distributed on different surfaces, after any cutting edge is worn, the countersink and the chamfer can be detached to rotate by a corresponding angle and then be installed, other cutting edges are used, the service life of the cutter is prolonged, and the processing cost is reduced.
