Problems solved by technology
It will also expand the diameter of the drilled hole, and the unequal radial force of the two cutting edges of the drill will cause the aperture to expand; the cutting and deviation of the horizontal lathe when drilling is also an important reason for the expansion of the aperture; in addition, the radial runout of the drill is also Causes of pore size enlargement
Poor surface quality of holes
The drilling chips are wide and are forced to roll into a spiral shape in the hole. When they flow out, they rub against the hole wall and scratch the processed surface. In addition, the axial force is large during drilling, which affects the drilling effect. This is mainly caused by the drill bit. caused by the chisel edge, therefore, a drill device is proposed to solve the above problems

The invention discloses a drill device. The drill device comprises a drilling cap, fixing devices, steel cones, a drilling tool, a tightening hole, a rigidity graduated scale, rubber sleeves, a steel column and a gasket; the drilling cap is mounted on the upper surface of the gasket, and one end of the drilling cap is arranged inside the steel column; the gasket is mounted at one end of the steel column; the tightening hole is formed in the surface of the steel column, and does not penetrate the interior of the steel column; the drilling tool is mounted at one end of the steel column, penetrates the interior of the steel column and is in tight connection with the drilling cap at the top end of the steel column; the rigidity graduated scale is arranged inside the steel column, and can freely move; the fixing devices are arranged on the surface of the rigidity graduated scale, and the steel cones are arranged at one ends of the fixing devices; the rubber sleeves are arranged at one end of the rigidity graduated scale, and the rigidity graduated scale is embedded into the rubber sleeves; and the drill device is compact in structure, long in service life and suitable for being used and popularized, and has the good economic benefits and social effects.
Description
technical field [0001] The invention relates to the technical field of drilling, in particular to a drilling device. Background technique [0002] In real life, there are many places that need to use drilling, and there are some problems in drilling now, which will make the drill easily deflected. Due to the inaccurate centering due to the influence of the chisel edge, the drill bit is easy to be deflected when cutting; and the rigidity and guiding effect of the drill bit are poor, and the drill bit is easy to bend when cutting. When drilling a hole on a drilling machine, it is easy to cause the axis of the hole to deviate and not be straight, but the hole diameter does not change significantly; when drilling a hole on a lathe, it is easy to cause a change in the hole diameter, but the axis of the hole is still straight. Before drilling, the end face should be processed first, and a cone hole should be pre-drilled with a drill bit or a center drill to facilitate the cen...
