Abstract

The utility model relates to a disk-type milling cutter for machining of metal cutting, particularly a clip-type combined disk-type milling cutter. The outer circle of a cutter head (5) is provided with an equispaced groove (8), and the bottom surface (9) of the groove is provided with an inclined scapular surface (12). A cutter seat (13) is arranged on the inclined scapular surface, and a clamping block (2) is positioned in the groove and is fixedly connected with the cutter head by a fixing screw (3). A cutter blade (1) is positioned between the cutter seat and the clamping block, and the abutted surface of a bevel (10) of the clamping block and the cutter blade keeps perpendicular to the end face (4) of the cutter head and forms an oblique angle alpha with the central line of the cutter head and the oblique angle alpha is the same as the rake angle of the inclined scapular surface arranged on the bottom surface of the groove. A gap is arranged between the lower surface (11) and the bottom surface of the clamping block. When the disk-type cutter needs to be sharpened, the fixing screw is loosened, and the cutter blade rotates 90 DEG and is rearranged and fixed on the cutter head. The utility model has the advantages of convenient sharpening of the blade man-hour saving, high efficiency and low manufacture cost.

Description

Clipping type combination order milling cutter

One, technical field

The utility model relates to metal cutting machinery machining tool.

Two, technical background

In the metal current machining, monoblock type dish milling cutter is generally integrally welded by blade and cutterhead.This dish milling cutter is in machining process; especially roughing operation; the cutting output of per pass operation is big; the sharpening of blade is very frequent; Sharpening a knife blade during special milling band arc size R wants multiple working procedure just can finish, and the secondary process time is long; in extensive machining, can influence the raising of operating efficiency.

Three, summary of the invention

The utility model adopts clipping type combination order milling cutter, and blade is fixed on the cutterhead by clamping device, when the needs sharpening, only need unclamp hold-down screw, with the blade half-twist, reinstalls and is fixed on the cutterhead, can continue Milling Process, and is time saving and energy saving.

The utility model is achieved in that a kind of clipping type combination order milling cutter, offer uniform groove on the cutterhead cylindrical, its bottom surface is provided with oblique omoplate face, tool rest places on the oblique omoplate face, clamp is arranged in groove, be fixedly connected by hold-down screw and cutterhead, blade is between tool rest and clamp, the binding face of clamp inclined-plane and blade, keep vertical with the end face of cutterhead, become an oblique angle α with the cutterhead center line, and identical with the inclination angle of oblique omoplate face on the groove floor, gapped between clamp lower plane and the bottom surface.

Four, description of drawings

Fig. 1 is the schematic diagram of clipping type combination order milling cutter; Fig. 2 is that the A of Fig. 1 is to partial view.

Among the figure, 1 is blade, and 2 is clamp, and 3 is screw, and 4 is end face, and 5 is cutterhead, and 6 is cutter axis, and 7 is pressing plate, and 8 is groove, and 9 is the bottom surface, and 10 is the clamp inclined-plane, and 11 is lower plane, and 12 is oblique omoplate face, and 13 is tool rest.

Five, preferred forms

Preferred forms of the present utility model is provided by following accompanying drawing.

Referring to Fig. 1, shown in Figure 2, on cutterhead 5 cylindricals, offer 12 uniform grooves 8, its bottom surface 9 is provided with oblique omoplate face 12, tool rest 13 places on the oblique omoplate face 12, clamp 2 is arranged in groove 8, be fixedly connected by two countersunk head cylinder soket head cap screws 3 and cutterhead 5, the carbide alloy titanium nitride coating blade 1 of square four sides cutting edge band R is between tool rest 13 and clamp 2, the binding face of clamp 2 and blade 1 keeps vertical with the end face 4 of cutterhead 5, becomes an oblique angle α with cutterhead 5 center lines, and identical with the inclination alpha of oblique omoplate face 12 on groove 8 bottom surfaces 9, keep the gap between clamp 2 lower planes 11 and the bottom surface 9.When the dish milling cutter need carry out sharpening because of wearing and tearing, only need unclamp hold-down screw 3 and unclamp, with blade 1 half-twist, reinstall and be fixed on the cutterhead 5.12 blades 1 are installed on cutterhead 5, and 166.7 millimeters of outer rim processing diameter D=Φ are greater than cutterhead outside diameter D _oThe end face of blade 1 is higher than the end face 4 of cutterhead 5, the installation oblique angle of clamp 2 and the inclination angle of tool rest 13 are α=10 °, hold-down screw is a M5 countersunk head cylinder soket head cap screw, in the time of the cutting edge R=(1.5～5) of blade 1 millimeter, reliable operation during this combination order milling cutter uses, sharpening is very convenient, the efficient height, processing cost is low.

Claims (1)

1, a kind of clipping type combination order milling cutter, it is characterized in that offering uniform groove (8) on cutterhead (5) cylindrical, its bottom surface (9) is provided with oblique omoplate face (12), tool rest (13) places on the oblique omoplate face (12), clamp (2) is arranged in groove (8), be fixedly connected by hold-down screw (3) and cutterhead (5), blade (1) is positioned between tool rest (13) and the clamp (2), the binding face of clamp inclined-plane (10) and blade (1), keep vertical with the end face (4) of cutterhead, become an oblique angle with the cutterhead center line, and identical with the inclination angle of oblique omoplate face on the groove floor, gapped between clamp lower plane (11) and the bottom surface.
