<p>PURPOSE: To provide a head clamping device in which centering accuracy in a spindle part of a head (drill head or tamper head) becomes so favorable, making improvements in operability, and not only a retention of this centering accuracy becomes facilitated but also any nonconformity such as generation of heat in a quill part due to deformation in a clamp, the earlier wear of a bearing, or the like is solved. CONSTITUTION: A male side taper part 7 of a clamp 1 is pressed in a female side taper part 11 by means of tightening of fastening means at plural spots of each peripheral part of the clamp 1 and a flange 3, and this male side taper part 7 is diametrally contracted, making it hold a quill 23, and the flange 3 is connected to a cell feeder body 20, and further this flange 3 is connected to a drill head 30 by a clamping means, then this drill head 30 is connected to the cell feeder body 20.</p> |
