Milling cutter with adjustable finish machining face

Abstract

The invention discloses a milling cutter with an adjustable finish machining face, comprising a cutter body, a cutting blade, an axial positioning block and a locking piece, wherein at least one of containing chambers capable of containing the axial positioning block are arranged on the cutter body, the axial positioning block is slidably arranged in the containing chambers, the cutting blade is arranged at one end of the axial positioning block and fixed by the locking piece, an axial driving hole is formed on the axial positioning block, the inner wall of the axial driving hole is provided with a pair of opposite axial positioning faces, the axial driving hole is internally and slidably provided with an adjusting block, the outer wall of the adjusting block is in close contact with a pair of the axial positioning faces, the adjusting block is connected with the cutter body by a dowel screw, the axial cross section of the cutter body which passes through the point of a knife of the cutting blade is a datum plane, and an inclined angle between the projection line of the central axis of the axial driving hole in the datum plane and the projection line of the central axis of the dowel screw in the datum plane is not equal to 0 degree. The milling cutter with the adjustable finish machining face has the advantages of being capable of being bilaterally adjusted, and being continuously, equivalently and gradually adjusted.

Description

technical field [0001] The invention relates to the field of metal cutting, in particular to an adjustable finishing face milling cutter. Background technique [0002] In the metal cutting industry, face milling finishing has always been a difficult point. The pursuit of high-demand surface roughness has always been an important development direction of cutting tools. Stable precision retention, which puts forward higher requirements for tool manufacturing. Therefore, in order to reduce the difficulty of tool manufacturing, face milling finishing tools are generally made into adjustable structures. [0003] At present, an adjustment structure is known in the field of cutting processing, including a cutting insert, a movable positioning block, a wedge-shaped adjustment block and a locking mechanism. The moving positioning block extends along the tool axis. [0004] During the adjustment process of this structure, the angle deflection of the movable positioning block is oft...

Problems solved by technology

This adjustment structure can realize two-way adjustment, but due to the unique characteristics of the eccentric screw, the adjustment behavior of the tool cannot be adjusted in an equivalent and progressive manner during the adjustment process, that is, the same angle of rotation of the eccentric screw cannot be achieved in the axial direction. amount of movement, making it impossible to estimate the level of adjustment precision for this adjustment structure
