Abstract
The utility model discloses a high-precision wear-resistance reamer which relates to a cutter used for mechanical processing and is characterized in that the angles of cutter edges are changed with the changes of the number of the cutter edges and the sizes of circles; during the cutting process, the high-precision wear-resistance reamer can effectively reduce vibration, and can enhance the precision and smoothness of holes; on the grinding machine of a outer circle, a thick grinding wheel and a thin grinding wheel are installed simultaneously, which can enhance the high-smoothness grinding of ligament at one time, has a long service life and is beneficial to saving materials and cost.
Description
Technical field
The utility model relates to a kind of machining cutter, relates in particular to the wear-resisting reamer of a kind of high accuracy
Technical background
The present reamer that uses, blade is that five equilibrium is arranged on circumference, can produce periodic vibration during cutting, so the hole surface that cuts with scissors out is coarse and fineness is relatively poor, exist polygon or axially striped and spiral lamination, working life of reamer is also lower.
Goal of the invention
The purpose of this utility model is to eliminate above-mentioned defective, promptly eliminates periodic vibration, improves the quality in hole and the service life of reamer.This reamer is applicable to the processing in hole on various metal cast irons, the copper aluminum steel spare.
Summary of the invention
The utility model reamer sword tooth adopts not five equilibrium arrangement on circumference, all sword teeth have adopted all asymmetric arrangement again on diameter, the angle of all sword teeth changes with the change that increases with the reamer size of the sword tooth number of teeth, sword number of teeth amount increases, the angle of sword tooth just reduces, vice versa, and the size of cutter changes the also corresponding thereupon change of angle of sword tooth.There is not the problem of polygon and straight burr in the hole of cutting with scissors out, and fineness can reach Δ more than 10, avoided periodic vibration, and polygon and spiral lamination appear in the Kong Buhui that cuts with scissors out, and fineness can reach Δ more than 10, and circularity and tapering can reach 1 μ m, also will exceed 80-100 doubly than general reamer the service life of this reamer, can save steel in a large number, require the hole of Δ more than 10 to save the operations such as mill or grinding of spreading out, save great amount of manpower and material resources with its ream hydraulic part hole fineness.
The utility model reamer on cylindrical grinder, is loaded onto a slice coarse plain emery wheel simultaneously when grinding reamer ligament, a slice fine grinding wheel, and the best bright finish grinding that reamer can once be installed and once finish ligament, and can strengthen the precision and the fineness in hole.
Description of drawings
Figure one is the distribution situation of reamer model sword tooth when big.
Figure two is the distribution situation of reamer model hour sword tooth.
Specific embodiment
Shown in figure one, figure two, the angle of each sword tooth of reamer is all different, and what of the number of teeth change with the change of circumferential size, and the angle of each sword tooth is all different, as the circumference of figure one circumference greater than figure two, so the number of teeth of figure one sword tooth is more than figure two.
Claims (1)
1. the wear-resisting reamer of high accuracy is characterized in that the sword tooth of reamer adopts the not arrangement of five equilibrium on circumference, and all sword teeth are all asymmetric on diameter.
