| description | The utility model discloses an auxiliary supporting device for machining an indexable blade drill bit. In the prior art, a drill bit for machining an indexable blade belongs to a slender rod and is poor in rigidity, and a cutting edge of a cutter is too far away from a clamping part, so that vibration and bending are easy to occur during machining, and the precision of the cutting edge is influenced. The upper portion of the indexable blade drill bit is attached to a tip through a tip hole, the cylindrical outer surface of the tail portion of the tip is installed in a copper sleeve, the tail portion of the tip is connected with a screw A through threads, the upper portion of the screw A penetrates through an upper frame, and a spring is installed between the inner diameter of the copper sleeve and the outer diameter of the screw A. The upper frame is connected with the cylindrical shaft through a screw B, the middle of the cylindrical shaft is connected with the lower support through a screw C, a set of round |
