One drill bushing, the outer end of the locating shaft are provided with locking nut, and the keeper is fixedly installed on the fixed base plate and corresponded to curved
The end of arm is set.Using said structure, the cylindrical sleeve of curved boom is supported on locating shaft, the first drill bushing face bit bore position
Point, support the end of curved boom to be positioned after passing through notch by keeper, be then locked cylinder by locking nut, i.e.,
It can be drilled.
Further, the top of above-mentioned supporting plate is installed with fixed plate, and the second drill bushing is provided with the fixed plate, should
Second drill bushing is coaxially set with first drill bushing.Using said structure, the second drill bushing can further protect drill bit, prevent from boring
Head is swung, and the second drill bushing carries out first time importing, and the first drill bushing carries out second and imported, and upper and lower drill bushing is positioned apart, and mutually
Restrict, preferably protect drill bit, solve drill bit vibration problems.
Further, above-mentioned keeper includes locating piece and alignment pin, and the locating piece is installed vertically on the fixed seat
On plate, the alignment pin points to the supporting plate side, and the aperture of corresponding curved boom distal end faces is set.Using above-mentioned knot
Structure, support and be provided with counterbore on the terminal surface of curved boom in itself, therefore alignment pin is positioned beneficial to itself favorable factor, structure letter
Single, positioning is convenient.
Further, the fixed part of above-mentioned locating shaft is provided with spacing plectane, and the locating shaft fixes end face and is provided with fixing nut,
By the fixing nut and spacing plectane clamping brace plate, the fixed locating shaft.Using said structure, locating shaft dismounting side
And fixation just,.
Beneficial effect：
A kind of support curved boom drilling tool of the utility model, comprehensively targeted design, is taken and is positioned with axle, on axle
Increase drill bushing, limit the swing of drill bit, ensure that apex point is accurately positioned, so as to solve the piercing aperture because caused by being swung drill bit
The underproof phenomenon of go-no go end.
