Abstract
The invention belongs to the field of machining, and particularly relates to a self-centering anti-deviation vibration reduction hole machining tool. The self-centering anti-deviation vibration reduction hole machining tool comprises a twist drill, an expanding drill, a center drill, a flat drill, a reamer, a boring cutter and the like, wherein a main cutting edge, an edge belt and an edge back are arranged in structure; on the end face view of the tool, a part of blade back contour lines are wedge-shaped contour lines which are different from the circle center of a machined hole, and the wedge-shaped contour lines and the hole wall of the machined hole form a wedge-shaped space; liquid is dragged into the wedge-shaped space, enters from a large gap, is extruded out from a small gap or is sealed, so that the pressure of the liquid is increased; and the liquid acts on the tool to prevent the tool from deflecting, and the machined hole is used as a process reference to guide the tool to feed. The liquid can convert system vibration energy into liquid pressure energy, so that system vibration is absorbed, the system vibration amplitude is reduced, and the hole machining quality is improved. A substantive improvement scheme is proposed for standard parts such as the twist drill and the like, and the tool has a broad application prospect. The scheme is simple, easy to implement and low in cost, and is a technical breakthrough.
Description
technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a self-centering anti-deflection and vibration-reduction hole processing tool. Background technique [0002] Hole processing tools include twist drills, reaming drills, center drills, flat drills, reamers, boring tools, etc. The most commonly used tool for hole machining is the twist drill, which is named after its chip flute in a spiral shape and shaped like a twist. The chip flute has 2 flutes, 3 flutes or more flutes, but 2 flutes are the most common. Twist drills can be clamped on manual or electric hand-held drilling tools or on drilling machines, milling machines, lathes and even machining centers. Most drill materials are high-speed tool steel or hard alloy. The reaming drill is similar to the drill bit, the drill bit drills the bottom hole, and the reaming enlarges the bottom hole. The reaming drill has 3 to 4 margins, no chisel edge, and the change of...
