Abstract
A mechanical clamped plain milling cutter with 315 millimeters diameter of the cutter head is composed of a cutter body, a pressing block, a pad block, a hard alloy blade, a pressure spring, a bevel nut and sixteen screws. The cutter body is provided with a groove in the radial direction, and the groove fixes the blade by the bevel nut and the pressing block. The movement of an adjusting block on the end plane achieves the adjustable radial direction precision and the shaft direction precision of the blade.
Description
The present invention relates to the big plane of Milling Process, diameter more than 315 millimeters, clip type, carbide indexable face-milling cutter, it has improved the efficient of Milling Process, has excavated the potentiality of large-scale Milling Process lathe.
Known produce diameter greater than 315 millimeters face milling cutters cutterhead processes in, because of the cutter hub diameter is bigger, and on the structure adopt on the cutter hubs axially groovedly more, the vertical lift height of general universal milling machine is limited; Simultaneously, universal rotary anchor clamps center height does not satisfy requirement yet, and this has just caused the cutter hub anufacturability relatively poor; On the blade clamping mode, usefulness be the Wedge-type structure, after blade is clamped, can produce the inconsistent phenomenon of chip curling groove height; On blade location and since radially with axially be not adjustable respectively, so be difficult for guaranteeing the radial run-out of cutter tooth and the design accuracy of Circular Run-out Tolerance; The difficulty of processing of cutter hub and each part is strengthened, influenced the raising with large-scale milling device production efficiency applied of major diameter machine folder face milling cutters.
The present invention at first be from the structure of the cutter body the axially grooved radially fluting that changes into, make that general universal machine tools can be processed, and do not need special tooling and anchor clamps when making large-scale dish face milling cutter body; On the blade clamping mode, change the squash type structure that band is adjusted piece and cushion block into, overcome blade and clamped the inconsistent phenomenon of back chip curling groove height; On the blade location, reach axial and radially distinguish adjustable degree, the requirement of having relaxed cutter hub and each part processing precision manufactures than being easier to; Simultaneously through adjusting the required precision that also reaches easily in the design to cutter tooth radial run-out and Circular Run-out Tolerance.
Specific implementation method of the present invention as can be seen from accompanying drawing, wherein Fig. 1 is the installation diagram of face milling cutters; Fig. 2 is structure of the cutter body figure; Fig. 3 is for adjusting block structural diagram; Fig. 4 is the crushing block structure chart; Fig. 5 is the cushion block structure chart; Fig. 6, Fig. 7 are surface nut and stage clip structure chart.
Face milling cutters are made up of cutter hub (1), adjustment piece (2), crushing block (3), cushion block (4), blade (5) and stretching screw (6), trip bolt (7), hold-down screw (8), surface nut (9), stage clip (10) as can be seen.
On the mode of clamping blade (5), be that surface nut (9) is contacted with crushing block (3) inclined-plane, as tension surface nut (9), make crushing block (3) produce staggered lateral displacement, thereby compressed blade (5); If unclamp surface nut (9), stage clip (10) can be eaily so change blade (5) with crushing block (3) bullet from blade (5); Stage clip (10) also plays the effect that prevents that crushing block (3) from radially deviating from simultaneously.The mode of this clamping blade (5) has guaranteed consistent on radial direction of the tool radius size of design and all crushing blocks (3), has reduced in the cutting because of being subjected to the inhomogeneous caused oscillation phenomenon of smear metal extruding and frictional force, has improved the stationarity of cutting.
On the orientation problem of blade (5), at first regulate adjustment piece (2) it is being moved radially, guarantee main cutting edge radial run-out precision, and then make cushion block (4) move radially the axial height of adjustable side sword.This result that radially can adjust respectively with the axial location precision, after assembling, cutter can have higher precision, can reach the requirement in the design.Also make when making knife part simultaneously, on dimension precision requirement, relax to some extent.
Claims (2)
1, the big plane of processing, the indexable machine folder of squash type, blade face milling cutters, it is characterized in that: it is by cutter hub (1), levelling piece (2), crushing block (3), cushion block (4), blade (5) and tension spiral shell Nail (6), fastening screw Nail (7), fixedly spiral shell Nail (8), surface nut (9), stage clip (10) are formed.
2, it is characterized in that by claim 1 defined machine folder face milling cutters: radially slot on the end face of cutter hub (1), crushing block (3) contacts with surface nut (9) inclined-plane in the groove.
