Abstract
The utility model is pulley rib slot machining cutter, and solving oneself has pulley rib slot machining tool sharpening efficiency extremely low, the problem of machining accuracy difference.Blade (2) is fixed in the insert groove of knife bar (1) by the 1st housing screw (3), and pressing plate (4) is fixed on knife bar (1) by the 2nd housing screw and goes up and compress the 1st housing screw (3), and blade has arranged side by side multiple tooth.
Description
technical field:
The utility model is relevant with the process tool of the equipment such as automobile, household electrical appliances middle belt pulley.
background technology:
Belt pulley is one of most important part in V belt translation structure, is widely used in the various gearings of the industries such as automobile, lathe, household electrical appliances.Most of belt pulley manufacturing enterprise domestic at present uses traditional brazed shank tool (as shown in Figure 1) for the processing of its critical process V-type wedge groove more.Due to brazed shank tool by hand sharpening complete, the cutting-tool angle uniformity therefore causing sharpening to go out is very poor, and error is comparatively large, and point of a knife fillet is extremely nonstandard, and in reality processing, product to be processed dimension overproof phenomenon occurs often, and roughness can not ensure; The sharpening technique of brazed shank tool requires higher to workman's professional technique, and weld crack and rosin joint situation are also difficult to avoid simultaneously; Tool sharpening, tool change time are long, and V-type wedge groove adopts monodentate turning, and the chamfering of marginal portion and rounding adopt CNC turning tool to walk profiling and machine (as shown in Figure 2), and working (machining) efficiency is extremely low.
utility model content:
The purpose of this utility model is to provide one and realizes the disposable Precision Machining of multiple wedge slot, improves dimensional accuracy and the surface quality of belt pulley finished product, reduces number of changing knife and use cutter kind, greatly shorten the pulley rib slot machining cutter of single products process time.
The utility model is achieved in that
Blade 2 is fixed in the insert groove of knife bar 1 by the 1st housing screw 3, and pressing plate 4 to be fixed on knife bar 1 by the 2nd housing screw and to compress the 1st housing screw 3.Blade has arranged side by side multiple tooth.
Blade 2 and insert groove are similar isosceles trapezoidal structure, and the inscribed circle diameter of isosceles trapezoid is φ 12-φ 16mm, and the cutting edge of blade 2 comprises pulley rib grooved line cutting tip 5, smoothing circular arc 6, chamfering or rounding cutting tip 7, step processing part 8.
Blade has 3 teeth or 4 teeth or 5 teeth, and blade is that two-sided screw hole coordinates with the 1st housing screw, and turnable exchanges and uses, and the cutting edge in two faces all leaves anterior angle, and blade adopts hard alloy coating material.
The carbide alloy pulley rib slot machining cutter that the utility model provides adopts the overall construction design of belt pulley process tool.This cutter comprises the overall co-ordination of knife bar and blade, whole grooveds that simultaneous manufacturing completes belt pulley can be realized, No. one time finish turning just can complete multiple V-type wedge groove, and the chamfering of V-type wedge groove edge part, rounding and step, no longer needs copying and deburring.Thorough change brazed shank tool production model before this, greatly improves dimensional accuracy and the surface quality of belt pulley finished product, reduces number of changing knife and use cutter kind, greatly shortening single products process time.
The utility model has the following advantages:
1. cutter adopts machine clip variable-position design, and the features such as the uniformity of blade and interchangeability substantially increase production efficiency and the Product Precision of pulley rib groove.
2. the disposal molding processing of belt wheel grooved, edge step, circular arc chamfering when cutter meets use, saved a large amount of repetition tool changing tool setting time, the use kind of cutter reduces to 1 cutter by original 3 cutter, and the process time of single products shortens about 1/3.
3. blade adopts hard alloy coating material, and cutting-tool's used life improves more than 1 times.
4. it is attractive in appearance that the design for aesthetic incorporated in the design of cutter makes product have more, and relative to welded type or insert, improves the class of product.
accompanying drawing illustrates:
Fig. 1 is the hand mill formula belt pulley V-type wedge groove tool sharpening schematic diagram that oneself has.
Fig. 2 is traditional copying schematic diagram such as belt pulley chamfering, step.
Fig. 3 is the utility model cutter structure and machining sketch chart.
Fig. 4 is the utility model blade schematic diagram.
