Abstract
The invention discloses an adjustable type countersink. The adjustable type countersink comprises a tool bar, a countersink, a depth adjusting sleeve, a limiting sleeve and a locking nut, wherein the countersink is fixed to the end part of the tool bar; a threaded hole is formed in the axial line of the depth adjusting sleeve; a part of the peripheral wall of the tool bar is connected into the threaded hole through threads; the depth adjusting sleeve is arranged in the limiting sleeve through a bearing; the countersink stretches out of the end surface of the limiting sleeve; the locking nut is in threaded connection with the peripheral wall of the tool bar which is far away from one side of the limiting sleeve; the depth adjusting sleeve can be locked by rotating the locking nut towards the limiting sleeve after the distance between the end surface of the countersink and the end surface of the limiting surface is adjusted and determined by rotating the depth adjusting sleeve. The adjustable type countersink disclosed by the invention is adjustable, the distance between the end surface of the limiting sleeve and the end surface of the countersink can be adjusted according to needs, and depth consistency of a machined counter bore is ensured.

Summary of the invention
The object of the present invention is to provide a kind of adjustable counterbore countersink, thus overcome conventional rocker drilling machine counterbit and process counter sink, depth error difficulty controls unified shortcoming.
For achieving the above object, the invention provides a kind of adjustable counterbore countersink, comprise knife bar and be fixed on the counterbore countersink of described knife bar end, also comprise: depth adjustment cover, its axis is provided with screwed hole, and the part perisporium of described knife bar is threaded connection in described screwed hole; Stop collar, described depth adjustment cover is located in described stop collar by bearing, and described counterbore countersink extends the end face of described stop collar; And locking nut, it is threadedly connected on the perisporium away from the described knife bar of described stop collar side, wherein, after the distance between the end face rotating depth adjustment cover adjustment counterbore countersink and the end face of stop collar is determined, toward stop collar direction rotational lock nut to lock depth adjustment cover.
Preferably, in technique scheme, described depth adjustment cover is fixed on described stop collar by bearing cap.
Preferably, in technique scheme, between described depth adjustment cover and described stop collar, be provided with sealing ring.
Preferably, in technique scheme, the cutter head place of described counterbore countersink is provided with guide finger.
Preferably, in technique scheme, described counterbore countersink is fixed on the end of described knife bar by locking nut.
Compared with prior art, the present invention has following beneficial effect:
Counterbore countersink of the present invention is adjustable counterbore countersink, can adjust the distance between the end face of stop collar and the end face of counterbore countersink as required, guarantees that the counter sink degree of depth of processing is consistent.
