Problems solved by technology

This data is not to be understood as limiting the scope of protection
[0010] But there is a problem in such centrifugal force controlled countersinking tools, that is, due to the centrifugal force, the insert can be reliably brought into the favorable working position, but the insert cannot be easily turned back to the inactive position

Embodiment Construction

[0047] exist figure 1A simple form of countersinking tool 1 is described in , which essentially comprises a cylindrical base body 2 , which is driven in rotation along its longitudinal center axis, and in the illustrated embodiment, for example in the direction of the arrow 21 .

[0048] In the interior of the main body 2 there is provided a supply opening 15 for the pressure medium. For reasons of simplification, it is assumed in the following description that the pressure medium is a coolant which is used not only for the pressure medium control of the blade 8 but also for cooling and rinsing the blade chamber 5 and the blade window 6 .

[0049] An approximately cylindrical blade housing 3 , in the interior of which a longitudinal bore is guided in the form of a control channel 13 , is arranged on the front face of the basic body by means of fixing screws 4 . In the control channel 13 , the flow of the control medium 14 in the direction of the arrow 16 is shown.

Abstract

The invention relates to a pressure-medium-controlled countersinking tool (1). The pressure-medium-controlled countersinking tool (1) comprises a blade (8) which can be operated by means of the input of the pressure medium, the blade can move to a rotating-outwards stretching-out operating position and a rotating-inwards taking-back non-cutting position in a pivoted manner, and can move between the operating position and the non-cutting position in a pivoted manner. The blade moves to the rotating-outwards stretching-out operating position and the rotating-inwards taking-back non-cutting position by means of the pressure medium. By means of a change-over valve controlled by the centrifugal force, the pressure medium can be switched between a first control channel (13) and a second control channel (43), and therefore the blade can be rotated inwards by means of the pressure medium of the first control channel or rotated outwards by means of the pressure medium of the second control channel, the pressure medium directly acts on a first pressure surface (18) of the blade from the outflow opening of the first control channel, and the pressure medium directly acts on a second pressure surface (20) of the blade from the outflow opening of the second control channel.

Description

[0001] This application is a divisional application of the original invention patent application with an application date of March 12, 2010, an application number of 201010135283.2, and an invention title of "Cosmerser controlled by pressure medium". technical field [0002] The invention relates to a pressure-medium-controlled, in particular coolant-controlled, countersink. Background technique [0003] From the development of the Swedish company Grandlund, coolant-controlled countersinking tools are known, but in the pivoting movement of the countersinking tool, the actuation is not directly via the cooling medium flowing out of the coolant channel, but via the piston-cylinder structure. [0004] The term "counterboring tools" is understood here to mean all cutting tools suitable for countersinking flats and countersinking. Therefore, not only forward countersinking but also backward countersinking are involved. The term “advance countersink” is understood to mean a count...
