Convertible milling edge-type milling cutter bar for processing constant-depth tooth arc-bevel gear

Abstract

The invention discloses a convertible milling edge-type milling cutter bar for processing a constant-depth tooth arc-bevel gear, and belongs to the technical field of cutters, and solves the problemsthat a rhombic cutter blade is liable to wear and be in failure, and there is only one cutter edge on one rhombic cutter blade. The convertible milling edge-type milling cutter bar includes a cutter body, wherein a half of rhombic groove is formed on one end thereof; a rhombic bearing sheet is arranged on the bottom of the groove and a rhombic cutter blade is arranged on the rhombic bearing sheet.The rhombic cutter blade is fixed to the rhombic bearing sheet via bolts. Three recess grooves are formed respectively at each of two sides of the diagonal line of the rhombic cutter blade. Cutting edges are arranged on a pair of opposite edges of the rhombic cutter blade. If the cutting edges on one side of the cutter bar are damaged, the rhombic cutter blade can be rotated by 180 degrees for installation just by loosening the bolt without detachment of the cutter blade from a cutter head, so that resharpening and reinstallation of the cutter bar are avoided, and utilization rate of the cutter bar is improved. Abrasion on the rhombic cutter blade is reduced and service life of same is prolonged since the recess grooves are distributed on the front blade surface.

Description

technical field [0001] The invention specifically relates to a convertible milling edge type milling cutter bar for processing contour-tooth arc bevel gears, and belongs to the technical field of cutting tools. Background technique [0002] The invention relates to a convertible milling blade type milling cutter bar for processing contour bevel gears. The contour bevel gear milling cutter is a key tool for processing contour bevel gears. It is used in aviation, aerospace, ships, automobiles, and agriculture. It is more and more widely used in industries such as machinery and manufacturing machine tools. At present, the arc bevel gear milling cutters used in these industries have accurate blade positioning and high precision requirements. Once the blade is damaged, it needs to be removed for regrinding and reinstalled. , the workload will be greatly increased, and when the milling cutter is milling, the rake face will wear out and fail, accompanied by a large amount of cuttin...
