Abstract
The utility model relates to a novel turnable cutter, which is composed of a cutter body, a blade and screws, wherein, a cutting edge which is projected between the top surface of the blade and the bottom surface of the blade is formed by that the both of an angle included between the front surface of the blade and the top surface of the blade and an angle included between the back surface of the blade and the bottom surface of the blade are obtuse angles; the blade is obliquely arranged and one or two intersected wedges in an acute angle are assembled on every surface of a clamping section corresponding to every cutting edge and an additional oblique plane, so that the blade is clamped by cutting force while screws only perform the functions of positioning and snagging the blade and preventing the blade from falling off. Being not punched, the blade has high yield rate, and without a blade shim, is obliquely installed rather than vertically installed. The blade has easy rotation and rolling, smooth chip removal, fewer parts and low cost, and can be made of a rigid alloy, ceramic material, etc. The utility model can be widely used for cutting tools, milling tools and other special tools.
Description
A kind of novel indexable tool relates to the change of blade shapes and the simplification of cutter structure.Blade can be made with carbide alloy, pottery, high hard high-speed steel or employing spraying ultrahard material etc., and this novel indexable tool can extensively be used as lathe tool, milling cutter and other special dedicated tool.
Existing machine clip variable-position cutter has three kinds of atresias (Fig. 1), circular hole (Fig. 2), counterbore (Fig. 3) with the blade branch, with blade load mode branch paperback (Fig. 4, Fig. 6) and upright dress (Fig. 5) two kinds is arranged.Upright dress blade cutting tool can not installed the edge bearing 5 below the paperback blade.The atresia blade is the yield rate height in compacting and sintering process, be not easy in the use therefrom to rupture, but shortcoming is because of adopting pressure type clamp structure (Fig. 4) pressing plate 3 to be in the cutter front of iron filings outflows, and the chip removal difficulty, and blade can not found dress.Circular hole blade (Fig. 6) is packed into behind the cutter hub, and tool surface is smooth, row's smear metal smoothness, and the blade transposition is convenient, but shortcoming is the clamp structure complexity, the upright dress difficulty of blade.Except that establishing edge bearing 5, also has edge bearing keeper 4, clamping element 3, clamp screws 6, clamping auxiliary 2 etc.Counterbore blade (Fig. 5, upright dress) the cutter hub clamp structure of packing into is concise, and upright dress is convenient in surfacing, all must unload screw 3 but shortcoming is blade transposition and loading and unloading, operation inconvenience, and percent defective is higher in compacting and the sintering.The common drawback of above-mentioned several cutters be clamping element over-burden, should bear the pretightning force that blade puts in place, bear the reaction force under the cutting force effect again, all do not utilize the cutting force clamping blade.
The purpose of this utility model provides a kind of novel indexable tool, make all many-sides such as its clamping, making, installation and use all overcome the deficiency of above-mentioned existing machine clip variable-position cutter at cutter, and gather its advantage, and provide a kind of optimization cutter that utilizes cutting force to clamp fully.
The purpose of this utility model is to realize in the following way: cutter is made up of cutter hub, blade, screw.2. 1. the blade front be the obtuse angle with bottom surface angle 3. with end face angle and blade back 4., with form the bottom surface 3. and the outstanding bite of end face between 4. 8., intersect one or two crossing acute angle wedge shape △ X, the △ Y that forms at the corresponding retaining part of each cutting edge of blade by each face and the clamping ramps assembly of setting up, only 5. the blade that is not covered with the blade periphery for cutting edge need set up clamping ramps.The blade angle mount is gone in the cutter hub.Cutter hub fluting shape matches with the angle mount blade.A blade is established a screw, as stumbling blade.
Further describe below in conjunction with embodiment and accompanying drawing.

Advantage of the present utility model and techno-economic effect are as follows:
(1) cutter knife atresia, yield rate height in compacting and the sintering. (2) tool surface is smooth, row's smear metal smoothness. (3) angle mount replaces vertical dress to need not to add expensive edge bearing. (4) clamp structure is very concise, adopts clamping element that screw is only arranged. It does not bear cutting force, and cutting force is born by cutter hub. Its effect is to guarantee accurately to put in place when blade is packed into, stumbles blade, makes cutter block blade when the unlikely disengaging cutter hub of blade and interrupted cut in anti-dress, lifting and carrying. Through evidence, after the indexable angle mount blade of clip is packed cutter hub into, under the continuous cutting condition, remove clamping element, cutting is fully normal. (5) blade transposition loading and unloading are very convenient, only need a little loosening screw, need not unload, can be with blade transposition, upset. (6) having realized the cutting force clamping blade, is optimizing structure of a kind of science, will speed up the development of cutter, improves the cutting technology level. (7) utilize cutting force to clamp, clamping is firm, guarantees that the breakage rate of blade lowers greatly. (8) cutter clamping in addition part greatly reduce, cutter only has cutter hub, a blade, a screw, simplifies manufacture difficulty, reduces manufacturing cost.
