Cutting component

Abstract

The invention discloses a cutting component which is suitable for a swinging power tool that an output shaft encircles an axis to conduct swinging motion. The swinging power tool comprises a motor and a transmission mechanism which is used for converting rotating motion of the motor into the output shaft encircling the axis to conduct swing motion. The cutting component is composed of a main body, an installing hole and a cutting portion, the main body is longitudinally extended, and the cutting portion is acted on a workpiece to be machined. The main body limits an axis which is longitudinally extended, and the installing hole is formed at a first end of the main body and connected with the swinging power tool. The cutting portion is arranged at a second end of the main body. The cutting portion consists of a first cutting portion and a second cutting portion. The cutting component is characterized in that the second cutting portion is horizontally protruded out of the first cutting portion, and the first cutting portion cuts the workpiece to be machined along the feeding direction. The second cutting portion cuts the workpiece to be machine along the direction perpendicular to the feeding direction. The cutting component has the advantages that the cutting component which is arranged on the swinging power tool and the second cutting portion which is horizontally protruded on the first cutting portion can effectively reduce vibration, effectively improves cutting efficiency and effectively improves chip removal efficiency.

Description

technical field [0001] The present invention relates to a cutting element, in particular to a cutting element used on a hand-held oscillating power tool. Background technique [0002] The multi-function machine is a common hand-held oscillating power tool in the industry. Its working principle is that the output shaft performs oscillating motion around its own axis. For example, U.S. Patent USRE36909 discloses a driving structure for an oscillating power tool, which includes a casing, a motor installed in the casing, and a main shaft driven by the motor. The main shaft has a rotation axis and an eccentric portion offset from the rotation axis. The fork is driven by the main shaft and operatively connected to the working unit. One end of the fork is pivotally connected to the output shaft, and the other end forms a pair of branched forks and is stuck on the eccentric part of the main shaft. The output shaft and the rotation axis of the main shaft are roughly Vertically, the ...

Problems solved by technology

When the user operates the saw blade 4' to cut the workpiece to be processed, since the saw blade 4' swings around the axis of the output shaft itself, the frequency of its swing can be set to about 10,000-25,000 times per minute, and its swing angle Can be set between approx. 0.5° and 7°, while in the case of this high-frequency oscillation the cutting element cuts in the direction of feed indicated by the arrow D, limited and increasingly larger by the flanks of the workpiece to be machined The frictional resistance of the saw blade. When the ordinary saw blade cuts the workpiece to be processed, the saw path is theoretically a trapezoidal shape, and the range of the left and right swinging motion of the saw blade is gradually limited, so that the cutting efficiency and chip removal of the saw blade It cannot be realized step by step until the saw blade is locked and cannot be pushed forward

At the same time, during the cutting process, due to the large vibration generated by the high-frequency swing, the user will feel numb when using it, which will affect the operating comfort
