Abstract
An indexable double-end helical-edge ball-end milling cutter comprises a double-end helical-edge ball-end milling cutter blade and a cutter arbor, one end of the cutter arbor is provided with a positioning notch, in which a second positioning face is arranged, the cutter arbor is provided with a threaded hole which runs through the positioning notch, the double-end helical-edge ball-end milling cutter blade is provided with a front helical edge and a rear helical edge, a rear cutter face of the milling cutter blade is provided with a first positioning face, the blade is also provided with a positioning hole, and is inserted into the positioning notch, the first positioning face on the blade clings to the second positioning face in the positioning notch of the cutter arbor, and a positioning screw passes through the threaded hole and the positioning hole to fix the blade in the positioning notch. Since the blade is provided with the front and the rear helical edges, when one of the helical edges is damaged, the milling cutter can be shifted to use the other helical edge, multiple specifications of blades can be suitably mounted in the positioning notch, consequently, the utilization rate of the cutter arbor is increased, and thereby the use cost can be reduced.
Description
Technical field
The utility model relates to a kind of indexable milling cutter, especially relates to level.
Background technology
Indexable rose cutter is applied to the accurate milling of curved surface of workpiece usually, traditional rose cutter has two kinds, a kind of is single head, one end is a cutting edge, and the other end is a locating surface, mainly applies to the Precision Machining of workpiece, its advantage is that cutting is brisk, the precision height, but owing to have only an end to use, so the use cost height; Two 1 kinds is common double end, can use at two ends, but cutting edge is a straight line, and the hemisphere cutting edge can only be arranged, and the scope of application is narrow relatively, the knife bar of the necessary single correspondence of every specification blade of while, because straight sword cuts, cutting force is big, thereby influences the workpiece crudy simultaneously, the service life of precision and cutter.
In sum, indexable rose cutter of the prior art exists or the use cost height, or technical problem such as the workpiece crudy is poor, and efficient is low.
The utility model content
The purpose of this utility model is to provide a kind of indexable twin-feed spiral sword rose cutter, both reduced the cutter use cost, the crudy and the working (machining) efficiency of workpiece have been improved again, solved indexable rose cutter exists or the use cost height comprehensively, technical problems such as the workpiece crudy is poor, and efficient is low
For achieving the above object, the utility model provides a kind of indexable twin-feed spiral sword rose cutter, comprise: twin-feed spiral sword rose cutter sheet and knife bar, knife bar one end is provided with locating slot, spiral blade and rear screw blade before twin-feed spiral sword rose cutter sheet is provided with, twin-feed spiral sword rose cutter sheet is fixed in the locating slot by dog screw.
Described spiral blade smoothly intersects at axis with two helical edges of end, and two ends week sword helix smoothly intersects at axial plane.
Described cutter blade is provided with first locating surface, and first locating surface is positioned on the back knife face of cutter blade, and cutter blade is provided with locating hole.
The end of described knife bar is provided with screwed hole, and this screwed hole runs through locating slot, and blade is packed into behind the locating slot, locating hole and screwed hole up/down perforation on it.
Described knife bar is provided with handle of a knife, and knife bar and handle of a knife can be made into integration, and knife bar and handle of a knife can also be welded.
But a plurality of specification blades of described knife bar clamping.
Be provided with second locating surface in the described locating slot, second locating surface is identical with the first locating surface shape and size.
Compared with prior art, the utlity model has following advantage:
1. this indexable twin-feed spiral sword rose cutter, all there is helical edges at the blade two ends, and a helical edges has been scrapped and can have been used an other helical edges, has reduced the cutter use cost.
2. this indexable twin-feed spiral sword rose cutter, the blade cutting edge is a helical edges, reduces cutting resistance, thereby improves cutter life and crudy.
3. this indexable twin-feed spiral sword rose cutter, first locating surface is positioned on the back knife face of blade, blade interfix hole; Simultaneously, according to the product specification difference, close specification location specification can be identical, thereby make the specification knife bar can corresponding plurality of specifications blade, reduced use cost.
4. this indexable twin-feed spiral sword rose cutter, knife bar is divided into monoblock type and two kinds of structures of welded type, can satisfy the high rigid demand of client to cutter, promotes workpiece crudy and production efficiency.
