Abstract:
1. A device for checking countersink dimensions comprising: a measuring head associated with a spindle of a multi-axis process machine; and a processing unit operatively associated with the spindle to control spindle movements; the measuring head comprising a contact element that can be inserted at least partly into a countersink and a comparator element for detecting an extent to which the contact element is inserted into the countersink; wherein the comparator element comprises a first portion slidably connected to the contact element along a sliding direction substantially parallel to an axis of the countersink; the first portion being designed to abut an edge of the countersink and to withdraw during insertion of the contact element; wherein the comparator element comprises a second portion integral with the contact element and having an end that moves into contact with the first portion to detect an extent to which the first portion withdraws; and wherein the first portion of the comparator element comprises a hollow first cylinder constituting a portion of the contact element and a second cylinder that slidingly fits into the hollow first cylinder; the second cylinder comprising three petals protruding from the hollow first cylinder for contacting the edge of the countersink.
