Abstract
The utility model discloses a kind of milling cutter back of tooth centralizer, comprise positioning disc, on described positioning disc, circumference is evenly equipped with at least three locating holes, alignment pin is provided with in described locating hole, described alignment pin is positioned on the concentric circles with positioning disc, and described alignment pin stretches out that locating hole is outer to contact with the milling cutter back of tooth and by milling cutter and disk coaxial positioning.Alignment pin just can by and by milling cutter and disk coaxial positioning, namely the difference center of the milling cutter back of tooth is concentric with disk, now at the endoporus by grinding machine or lathe process milling cutter, so just can improve the concentricity of the milling cutter back of tooth and endoporus, reduce the radial oscillation capacity of edge of milling cutter.
Description
Technical field
The utility model relates to fixture during a kind of milling cutter processing centre bore, particularly a kind of fixture of being felt relieved by the milling cutter back of tooth.
Background technology
When back-off profile milling cutter outer diameter D is greater than 100 millimeters, the radial oscillation capacity of blade generally should be less than 0.05 millimeter; When external diameter is less than 100 millimeters, the radial oscillation capacity of blade generally should be not more than 0.03 millimeter.Otherwise in process, the workpiece profile shape that profile milling cutter can be made to process produces larger error.And because each cutter tooth milling surplus is uneven, not only produce vibration, and the cutter tooth rapid wearing making indivedual load larger, greatly reduce the life-span of profile milling cutter.The radial oscillation capacity of blade, the nonconcentricity primarily of each tooth back curve of milling cutter and milling cutter endoporus causes, in the process of milling cutter processing, therefore ensure that the concentricity of the back of tooth and endoporus in use reduces the radial oscillation capacity of its blade for milling cutter and plays an important role.
Utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of milling cutter back of tooth centralizer, and on this fixture, milling cutter processing endoporus can improve the concentricity of the milling cutter back of tooth and endoporus.
Milling cutter back of tooth centralizer of the present utility model, comprise positioning disc, on described positioning disc, circumference is evenly equipped with at least three locating holes, alignment pin is provided with in described locating hole, described alignment pin is positioned on the concentric circles with positioning disc, and described alignment pin stretches out that locating hole is outer to contact with the milling cutter back of tooth and by milling cutter and disk coaxial positioning.
Further, described locating hole is that described alignment pin is slidably matched along its length in locating hole along disk diameter to the elongated hole extended.
Further, the other end that described positioning disc is relative with milling cutter is provided with the rotating disk with its coaxial rotation, and described rotating disk is provided with snail tooth, and described alignment pin to extend out to rotating disk direction outside locating hole and engages with the snail tooth on rotating disk.
The beneficial effects of the utility model: milling cutter back of tooth centralizer of the present utility model, comprise positioning disc, on described positioning disc, circumference is evenly equipped with at least three locating holes, alignment pin is provided with in described locating hole, described alignment pin is positioned on the concentric circles with positioning disc, and described alignment pin stretches out that locating hole is outer to contact with the milling cutter back of tooth and by milling cutter and disk coaxial positioning.Alignment pin just can by and by milling cutter and disk coaxial positioning, namely the difference center of the milling cutter back of tooth is concentric with disk, now at the endoporus by grinding machine or lathe process milling cutter, so just can improve the concentricity of the milling cutter back of tooth and endoporus, reduce the radial oscillation capacity of edge of milling cutter.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is schematic front view of the present utility model;
Fig. 2 is that schematic diagram is looked on a left side of the present utility model;
Fig. 3 is the schematic diagram of the utility model turntable.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail, as shown in the figure: the milling cutter back of tooth centralizer of the present embodiment, comprise positioning disc 1, positioning disc is coaxially arranged on grinding machine or lathe, on described positioning disc, circumference is evenly equipped with at least three locating holes 3, an alignment pin 4 is provided with in each locating hole 3, all alignment pins 4 are positioned at on the concentric circles of positioning disc 1, described alignment pin 4 stretches out outside locating hole and contacts with the back of tooth 21 of milling cutter 2, so at least three alignment pins 4 just can by and by milling cutter and disk coaxial positioning, namely the difference center of the milling cutter back of tooth is concentric with disk, now at the endoporus by grinding machine or lathe process milling cutter, so just can improve the concentricity of the milling cutter back of tooth and endoporus, reduce the radial oscillation capacity of edge of milling cutter.
Described locating hole can be circular hole, and alignment pin is fixed in circular hole, and the milling cutter external diameter that this sample holder can be felt relieved is fixed.
Described locating hole 3 also can be that corresponding alignment pin 4 is slidably matched along its length in locating hole, and the milling cutter external diameter that such alignment pin can be located is adjustable, and the adaptability of fixture is stronger along disk diameter to the elongated hole extended.
In such scheme, alignment pin can movement separately, and such operating efficiency is lower.For this reason, the other end that described positioning disc 1 is relative with milling cutter is provided with the rotating disk 5 with its coaxial rotation, described rotating disk 5 is provided with snail tooth 6, described alignment pin 4 to extend out to rotating disk 5 direction outside locating hole 3 and engages with the snail tooth 6 on rotating disk 5, rotate rotating disk 5, under the effect of snail tooth 6, can make alignment pin 4 simultaneously near or away from the center of circle of positioning disc, operate easier.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
