Abstract
The utility model discloses an indexable mechanically-clamped gear semi-milling cutter, which comprises a cutter body 1, side tooth blades 2, top tooth blades 3 and fastening screws 4. The side tooth blades 2 and the top tooth blades 3 are spirally arranged in a cutter body cutting zone in pairs and fixed on the cutter body by the fastening screws; the top tooth blades are convex R blades, the side tooth blades are concave R blades or straight-edge blades, and the two ore more adjacent groups of side tooth blades 2 and the top tooth blades 3 are mutually lapped so as to form a complete cutting edge. The indexable mechanically-clamped gear semi-milling cutter has the advantages that the rough machining and the semi-finish machining of a gear are completed at a time by using the same cutter, thereby replacing the rough milling, the slotting and the hobbing in the gear machining, improving the machining efficiency, dispensing with an expensive high-speed steel slotting or hobbing cutter and reducing the cost of the cutter; furthermore, the structure is simple, the assembly and the disassembly are convenient, the one-time machined gear tooth profile can achieve the precision of the tooth profile after the hobbing machining, and the adoption of an indexable mechanically-clamped structure improves the using rate of the cutter body and the blades.
Description
Technical field
The utility model belongs to the metal cutting technology field, particularly a kind of machine clip variable-position gear half finish-milling cutter.
Background technology
At present, domestic large gear profile processing main technique of having relatively high expectations is to carry out roughing with the gear roughing milling cutter earlier, and then adopts slotting or gear hobbing semifinishing, adopts grinding fine finishining at last again; Less demanding large gear profile processing main technique is to carry out roughing with the gear roughing milling cutter earlier, and then adopts slotting or gear hobbing fine finishining.This type gear flank profil technological process is longer, and hold facility is many, and working (machining) efficiency is low.
Summary of the invention
The utility model purpose promptly is to overcome the shortcoming of prior art, and a kind of machine clip variable-position gear half finish-milling cutter is provided, and this milling cutter construction is simple, and good impact resistance has improved working (machining) efficiency when simplifying the gear-profile processing process.
The purpose of this utility model is achieved through the following technical solutions: a kind of machine clip variable-position gear half finish-milling cutter, it comprises cutter hub, side teeth cutter blade, apical tooth blade and trip bolt, side teeth cutter blade and apical tooth blade are arranged in the cutter hub cutting region in groups spirally, and are fixed on the cutter hub by trip bolt; The apical tooth blade is protruding R blade, and the side teeth cutter blade is recessed R blade or straight knife sheet, faces two or more sets side teeth cutter blades and apical tooth blade mutually and overlaps out complete cutting edge mutually.
The apical tooth blade is protruding R blade, and the cutting edge that promptly is the apical tooth blade is the complete protruding R sword or the comprehensive sword of protruding R sword and straight sword.
The side teeth cutter blade is recessed R blade or straight knife sheet, promptly is that side teeth cutter blade cutting edge is complete recessed R blade or complete straight knife sheet or recessed R sword and the comprehensive sword of straight sword.
The apical tooth blade is meant the one or more blades near the cutter hub top, and the cutter hub top specifically is meant cutter hub cutting region maximum outside diameter part.
By top narration as can be seen, the utlity model has following advantage: the roughing and the semifinishing of gear are finished with same cutter is disposable, replaced rough milling in the Gear Processing, slotting or gear hobbing, improved working (machining) efficiency, reduced production cost, and simple in structure, easy to loading and unloading, the disposable gear-profile that processes can obtain gear hobbing processing back profile accuracy, adopt indexable clip type structure, improved the utilization rate of cutter hub and blade, and the working (machining) efficiency height, stable cutting.
Description of drawings
Fig. 1 is a side view of the present utility model;
Fig. 2 a is protruding R blade figure of the present utility model;
Fig. 2 b is the blade figure of recessed R of the present utility model and straight sword consubstantiality.
Among the figure: 1-cutter hub, 2-side teeth cutter blade, 3-apical tooth blade, 4-trip bolt.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described, as Fig. 1, Fig. 2 a and Fig. 2 b, a kind of machine clip variable-position gear half finish-milling cutter, it comprises cutter hub 1, side teeth cutter blade 2, apical tooth blade 3 and trip bolt 4, side teeth cutter blade 2 and apical tooth blade 3 are arranged in cutter hub 1 cutting region in groups spirally, and are fixed on the cutter hub 1 by trip bolt 4; Apical tooth blade 3 is the blade of protruding R sword and straight sword overlap joint, and side teeth cutter blade 2 is recessed R sword and the comprehensive blade that straight sword overlaps, and faces two or more sets side teeth cutter blades 2 and apical tooth blade 3 mutually and overlaps out complete cutting edge mutually.
