Description
Technical Field
The utility model relates to the field of machining equipment, in particular to a device for quickly drilling an inclined small-diameter hole by a bench drilling machine.
Background
Drilling inclined holes is usually processed by using a common milling machine, and generally, three conditions exist: (1) drilling a hole on the inclined plane; (2) drilling an inclined hole on the plane; (3) and drilling a hole on the curved surface. The conventional processing technology is used for processing the small holes at present: firstly, a plane is machined on an inclined plane by using a milling cutter, a reference is made for the subsequent machining, and then the twist drill is used for drilling. Such a method is a relatively common method, and when machining parts: the process steps are more, and a large amount of resources are occupied; large equipment is required to be used as a support, and the small bench drill cannot complete the action because the tool is changed; the debugging time is long, and the human resources are wasted; the size of the parts cannot be relatively small, and if the size is too small, the machine-adjusting time can be greatly increased, and the assembling and disassembling process is troublesome for operators.
The following problems also exist in the processing using a general milling machine:
1. the clamping position of the small-sized part is limited when the small-sized part is clamped, so that the small-sized part is inconvenient to clamp;
2. the aperture is small, and if the aperture is small, the conventional point hole and drilling operation cannot be carried out, and if a milling cutter is adopted, the cutter is too long in overhanging, so that the possibility of batch processing is reduced;
3. under the condition that the small holes are closer to the surface or other characteristics, the small holes are closer to other characteristics, so that the small holes are easy to break or factors influencing other characteristics appear, and the rejection rate of parts is increased;
4. the small hole is positioned on the inclined plane, and when the small hole on the inclined plane is machined, the position of the hole is unstable because a tool cannot be stably held on the inclined plane, and the phenomenon of knife hitting is easy to occur.
To sum up, when drilling the inclined hole, on one hand, if a common hole machining method is adopted, a common milling machine is used for machining, and a bottom edge of a milling cutter is used for machining, because the center of the hole is not perpendicular to the drilling plane. The single side of the drill is stressed, and the axial line of the drill deflects to one side and bends due to the radial component force acting on the cutting edge of the drill, so that the requirements on the correct position of a hole and the verticality of a drilled hole are difficult to ensure, and the drill is easy to break; on the other hand, the part is required to be convenient to clamp, the size of the part is required to a certain extent, the part cannot be too small and cannot be operated easily, and the processing difficulty is increased exponentially.
