Abstract
The utility model discloses an adjustable floating reamer made of hard alloy. The utility model is composed of two reamer heads and two steel bodies, wherein, the two reamer heads are respectively and fixedly connected with reversal end heads of the two steel bodies. Each edge surface forms a mirror surface. The end heads of the two steel bodies in the same direction are axially stacked, and are fixed by regulating screws. The utility model can realize the superfinishing on inner holes of non-ferrous metal and alloy workpieces, save the grinding procedure, raise the work efficiency and reduce the production cost.
Description
The utility model relates to a kind of aperture knife tool, is used for the various metal works of machining.
Present used this type of cutter (standard GB 4254-84), its cutter head surface roughness partly is Ra=0.32～0.1 μ m(
9～
10), i.e. A, B and D face Ra=0.32 μ m, C face Ra=0.1 μ m.Have only about Ra=2.5 μ m with this cutter bore hole processing back workpiece surface roughness, if workpiece requires high slightly then will process with mill, this will increase operation and change lathe, influence production efficiency, and generally also be difficult to the surface quality that reaches desirable with grinding for the workpiece of non-ferrous metal and alloy thereof.
The purpose of this utility model provides the carbide alloy that a kind of microstoning endoporus uses can regulate floating reamer, can very easily make the bore area of workpiece to be machined reach Ra＜0.3～0.1 μ m(during this cutter bore hole
9-
10), remove the mill manufacturing procedure from, enhance productivity.
The purpose of this utility model is achieved in that it is made of cutter head and steel body, and cutter head is two carbide bits of symmetry, and each blade face of cutter head is minute surface.Two cutter heads are connected in the reverse termination of two steel bodies respectively, and the homophase termination of two steel bodies is axially folded mutually, is fixed by adjustment screw.
This reamer is because each blade face of cutter head is a minute surface, and its surface roughness reaches Ra＜0.01 μ m(
14), and blade part is very sharp and do not have circular arc and occur.When being used for bore hole, can very easily make the bore area of workpiece to be machined reach Ra＜0.3～0.1 μ m(
9-
10).If the machine tool accuracy height is selected suitable cooling fluid simultaneously again, can make surface of the work Ra≤0.04～0.02 μ m(
12-
13).Need not grind manufacturing procedure and can reach desirable fineness.Solved the microstoning difficult problem of non-ferrous metal and alloy workpiece endoporus thereof.
Fig. 1 is structure chart of the present utility model.
Fig. 2 is cutaway view of the present utility model.
As can be seen from the figure, the utility model includes cutter head 3 and steel body 2.Cutter head 3 is two carbide bits of symmetry, and each blade face 4 of cutter head all is machined to minute surface with special technique, makes surface roughness reach Ra＜0.01 μ m(
14), the very sharp no circular arc of blade occurs.Two cutter heads are connected on the reverse termination of two steel bodies, and the homophase termination of two steel bodies is axially folded mutually, is fixed by adjustment screw 1.
