Wherein preferred technical scheme is, is provided with the positioning support pushing out ring of slew gear at described inner flange ring, and described inner flange ring, or is lifted in the cylindrical shell by suspension bracket on inner barrel or tubular framework by base support.
Further preferred technical scheme also has, and the barrel in described brace summer lower end is provided with the bushing plate that is connected with barrel, is provided with drill jig sleeve at bushing plate.
Further preferred technical scheme is that described slew gear cooperates with drill head and bushing plate, is used for finishing location and the drilling in processed centripetal hole.
Further preferred technical scheme also has, described drill head is the bench drilling head of a bed, drill head is connected with brace summer by screw-nut body, what the leading screw in the screw-nut body rotated is supported under the brace summer, in the end of leading screw the handwheel that moves radially for driving drill head is housed, nut is fixed on the drill head.
Further preferred technical scheme also has, and also is provided with slide rail under described brace summer, is provided with slide block at drill head, and slide rail cooperates the guiding that is used for drill head with slide block.
Further preferred technical scheme also has, at the other drill bit feeding handle that is provided with of the drill bit of described drill head.
Further preferred technical scheme also has, and is provided with the drill head location locking mechanism in a side of described drill head screw-nut body, locks described leading screw by the handwheel in the drill head location locking mechanism.
Advantage of the present utility model and beneficial effect are: adopt the centripetal hole drilling of this cylinder bore wall mechanism to have the perforating efficiency height in the punching of large cylinder barrel, it is convenient, accurate to be decided to be the position, in the situation that does not need mobile cylindrical shell, continuable from inside to outside punching on the barrel of large cylinder, the open defects such as it is high to have overcome simultaneously the labour intensity that generally spiles first expanded hole with electric hand drill again and cause, and the of poor quality and production efficiency in centripetal hole position is low.
