Abstract
The present invention provides a method for detecting molded lines of a forked blade root finishing milling cutter. Before the generation of a back angle of the cutter, a molded line is processed on a cutting edge of the cutter by a circular grinding method on a shovel bed. A radiation line is made through the center of the cutter, and a molded line of each cross section is completely consistent. A mandrel, a templet and a templet bracket are designed, the templet moves horizontally on the templet bracket, and the templet bracket does rotary movement around the center of the mandrel. Then, the back cutter surface has no back angle, and the molded line on the back cutter surface is a theory molded line. According to the projection principle, the molded line on the back cutter surface is consistent with the molded line on the cutting edge of the cutter, and then the molded line on the back cutter surface is measured for controlling the precision of the molded line on the cutting edge of the cutter. The present invention is a novel detecting method with accuracy and reliability, and can improve the processing quality.
Description
Technical field
The invention belongs to the manufacturing of disc-type line milling cutter, a kind of specifically machining and testing method of large diameter blade multifork root finish-milling cutter molded lines.
Background technology
" 851 " blade multifork root finish-milling cutter diameter that the original application people produces is ∮ 380mm, is the backed-off milling cutter of zero degree hook, and the formed cutter profile of rake face is the drawing theory shaped wire.Just can detect easily as long as be attached on the rake face adding man-hour by the designed model of drawing theory shaped wire.And 40 inches blade multifork root finish-milling cutter diameter is ∮ 490mm, in order to improve crudy, this cutter is designed to inserted cutter, has 15 ° of anterior angles, the cutting edge molded lines also has certain angle, and the radial dimension that 45 ° of cutting edges and flank of tool sword intersect formed intersection point has tolerance.Like this, measuring molded lines at rake face just has certain gap with theory shaped wire, and common backed-off milling cutter processing method and measuring method just can't be satisfied the demand, and this cutter is the manufacturing first time at home, and the non-avaible technology can be used for reference.
Summary of the invention
Purpose of the present invention is intended to provide a kind of brand-new detection method of blade multifork root finish-milling cutter processing.
Technical solution of the present invention is: the molded lines on the Tool in Cutting sword processed with the method for circle mill on gear milling lathe before the relief angle of cutter produces, make radiation by center cutter, each cross section molded lines should be in full accord, design a mandrel and model, the model frame, model moves horizontally on the model frame, the model frame is done gyration around the mandrel center, at this moment back knife face does not have relief angle, molded lines on the back knife face is a theory shaped wire, according to projection theory, molded lines on the back knife face is consistent with the molded lines on the Tool in Cutting sword, can be by measuring molded lines precision on the back knife face molded lines control Tool in Cutting sword.Its concrete grammar step is as follows:
(1) adopt the head of a bed and tailstock all to have top gear milling lathe;
(2) mandrel adopts centre bore location, two, and the cutter inner hole sleeve makes the cutter centre of gyration consistent with the mandrel centre of gyration on mandrel;
(3) have one section positioning cylinder on the mandrel and be used for frame model frame, the model frame is the V-block structure, this V-block frame also can freely rotate on the positioning cylinder of gear milling lathe mandrel, the side of V-block is by the cutter centre of gyration, and 45 ° of cutting edges of cutter guarantee by filling up corresponding slip gauge between V-block and the model bottom surface with the intersection point radial dimension of flank of tool sword;
(4) model is a profile of tooth, this model in use, the measurement plane of its model can pass through the cutter centre of gyration all the time, axially by the end face touch controls of model side and blade;
(5) on tooth block, design corresponding model molded lines by Tool in Cutting sword profile molded lines, and control model molded lines is to the size of model bottom surface with arrive the size of model side, the 45 ° of cutting edges of cutter and the intersection point of flank of tool sword are converted to the radially radius size of the centre of gyration to this intersection point to maximum excircle dimension, control the radially radius size of this intersection point with V-block and model, the molded lines of the cutter radial direction that processes like this is the cutter theory shaped wire.
Beneficial effect of the present invention: detection method accurately and reliably, practicality, can effectively improve crudy.
