For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of counter sink processing drilling tool; Described drilling tool comprises the drillstock that axially extends along the vertical direction of being convenient to the drill chuck clamping when using; The drillstock bottom is coaxial fixedly is equipped with and is used for the hole fluted drill of processing of the path section of counter sink; Above the fluted drill drill bit, be installed with the hole alloy blade of processing of at least two taper countersunk head portions to counter sink of being used for around circumferential distribution on the drillstock, the extended line of the cutting edge of each alloy blade tilts crossing with the central axis of drillstock.
Described drillstock comprises the coaxial alloy blade holder that is wholely set on main drillstock and the main drillstock in tubular construction, and in the hollow pipe inner chamber that fixedly is assemblied in main drillstock that described fluted drill is coaxial, the drill bit of fluted drill stretches out from the lower ending opening of main drillstock; Around circumferentially being provided with mounting groove, what described alloy blade was corresponding fixedly is assemblied in the described mounting groove on the outer peripheral face of described alloy blade holder.
The tube wall of described main drillstock circumferentially is evenly equipped with the axially extended separation trough of the main drillstock in a plurality of edges around tube wall, and the upper end of separation trough is hatch frame, and separation trough is separated the tube wall of main drillstock the clamping lobe that is a plurality of fluted drills that are used to be fixedly clamped.
The mounting groove of described alloy blade is along the radially extension of said main drillstock, and described alloy blade is weldingly fixed in the mounting groove through inlaying.
The top of described alloy blade holder has the positioning step that is used for drilling tool is carried out installing and locating when using.
The beneficial effect of the utility model is: the drillstock bottom of counter sink that the utility model provided processing drilling tool is provided with and is used for the hole fluted drill of processing of the path section of counter sink; At the hole alloy blade of processing of the taper countersunk head portion to counter sink of being used for around circumferential distribution of above the fluted drill drill bit, being provided with on the drillstock; For guaranteeing processing effect to the taper countersunk head portion of counter sink; The extended line of the cutting edge of alloy blade and the central axis of drillstock tilt to intersect, and add man-hour when using this processing drilling tool calcium silicate board for building to hole like this, and drillstock is installed on the drill chuck; Circumferential revolution along with drillstock; Fluted drill is accomplished the processing to counter sink path section, and alloy blade is accomplished the boring of the taper countersunk head portion of counter sink and reaming processing, the processing drilling tool time processing moulding that can be provided by the utility model of the counter sink on the structural lumber like this; Effectively raise the working (machining) efficiency of the counter sink on the structural lumber, reduce labour intensity.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the counter sink processing drilling tool that provides of the utility model.
The specific embodiment
As shown in Figure 1; A kind of embodiment of counter sink processing drilling tool; Counter sink processing drilling tool among this embodiment comprises the drillstock that axially extends along the vertical direction of being convenient to the drill chuck clamping when using; Drillstock mainly is made up of in tubular construction main drillstock 1 and coaxial 2 of alloy blade holders that are wholely set on main drillstock, and the clamping part of drill chuck clamping is convenient on the top of main drillstock 1 when using, and coaxial fixedly being equipped with is used for the hole fluted drill 4 of processing of the path section of counter sink in the hollow pipe inner chamber of main drillstock 1; On the tube wall of the main drillstock 1 in the present embodiment around circumferentially being evenly equipped with three separation troughs 11; Separation trough extends axially along main drillstock, and the upper end of separation trough is hatch frame, and three separation troughs are separated into a plurality of clamping lobes with the tube wall of main drillstock; Fluted drill 4 is fixedly clamped by a plurality of clamping lobes, and the drill bit of fluted drill stretches out from the lower ending opening of main drillstock.Described alloy blade holder 2 is positioned at the top of fluted drill drill bit; On the outer peripheral face of the large stretch of holder of alloy around circumferentially being provided with mounting groove; In the present embodiment; Mounting groove radially extends along main drillstock, and corresponding inlaying is welded with the alloy blade 3 that taper countersunk head portion holes and reaming is processed that is used for counter sink in mounting groove, and the extended line of the cutting edge of alloy blade and the central axis of drillstock tilt to intersect; For improving the installation rate of the processing drilling tool that is provided in the present embodiment, be provided with the positioning step that is used for drilling tool is carried out installing and locating when using on the top of alloy blade holder.
