Abstract
The invention relates to a novel shaft hole milling cutter which comprises a cutter head and a cutter shank fixedly connected with one end of the cutter head, wherein a plurality of cutter slots are formed in the surface of the peripheral side of the cutter head; first mounting slots are formed in the upper ends of the cutter slots, and second mounting slots are formed in the lower ends of the cutter slots; the diameters of the first mounting slots are smaller than that of the second mounting slots; first blades for processing a shaft hole are arranged in the first mounting slots; second blades for processing a countersink are arranged in the second mounting slots; communicated oil slots are formed in the axle centers of the cutter shank and the cutter head; branch oil slots connected with the first mounting slots and the second mounting slots are formed in the oil slots; a mounting hole is formed in the end face of the other end of the cutter head; a drill bit device is arranged in the mounting hole; the mounting hole is communicated with the end parts of the oil slots. The novel shaft hole milling cutter has the characteristics of simple structure, high processing efficiency, long service life, milling and drilling integration and the like, and capability of shaping the shaft hole by a one-step turning manner.
Description
Technical field
The present invention relates to machine tools technical field, particularly the novel axis hole milling cutter of one.
Background technology
For processing axis hole, endoporus should be processed, process counterbore again, existing turning cutting tool all uses different milling cutters to carry out milling for endoporus and counterbore, also has the workpiece for milling again of should holing, will change cutter to realize, so just seem pretty troublesome, efficiency is also low, when milling tool, can cannot continue because wearing and tearing shorten to use after blade uses a period of time.Therefore, people are provided with oil groove at handle of a knife, for adding lubricating oil just can lubricate cutter when using, prevent its wearing and tearing from accelerating, and reach the effect of lubrication and maintenance cutter.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of structure simple, working (machining) efficiency is high, and physical life is long, milling, and boring is integrated, and can carry out the milling cutter of turning shaping to axis hole.
Realize technical scheme of the present invention as follows:
A kind of novel axis hole milling cutter, comprise cutterhead, and the handle of a knife to be fixedly connected with cutterhead one end, the all side surfaces of described cutterhead are provided with multiple cutter groove, cutter groove upper end is provided with the first mounting groove, lower end is provided with the second mounting groove, first mounting groove diameter is less than the second mounting groove, described first mounting groove is provided with the first blade for processing endoporus, second mounting groove is provided with the second blade for processing counterbore, handle of a knife is provided with the axle center place of cutterhead the oil groove be connected, oil groove is provided with the branch's oil groove be connected with the second mounting groove with the first mounting groove, the end face of the other end of cutterhead is provided with installing hole, drill bit device is provided with in installing hole, described installing hole is connected with the end of oil groove.
Described drill bit device and installing hole are connected by screw fixing; drill bit device comprises terminal pad and drill bit; terminal pad and drill bit are formed in one; advantage is convenient to drill bit and cutterhead is connected and fixed; use and pack up all more convenient; installing hole comprise interconnective the first accommodating hole for accommodating terminal pad with for accommodating drill bit and the second accommodating hole being connected oil groove end; advantage drill bit oppositely can be installed when not using drill bit device; that drill bit does not expose; effectively protect drill bit, extend its service life.
The end of described second accommodating hole and oil groove is set to pyramidal structure, and advantage is on the drill bit that instills in the second accommodating hole of the lubricating oil be convenient in oil groove, prevents the waste that lubricating oil is too much.
On described terminal pad, uniform four have screw hole for mounting screw, and cutterhead is provided with the connecting hole corresponding with connecting hole, and advantage is convenient to dismounting cutterhead and terminal pad.
Have employed above-mentioned scheme, the first blade can be used for the endoporus processing axis hole, and the second blade, for processing the counterbore of axis hole, so just can carry out a turning to axis hole, saves the milling cutter changing different size and carrys out turning, simple and convenient; Oil groove can be used for adding lubricating oil, and the blade flowed on each cutter groove by branched bottom carries out lubricating and maintaining, and effectively protects blade, extends its service life; Can also hole to workpiece additionally by the drill bit device on cutterhead, first blade can also carry out face milling to drilled workpiece, effectively raise operating efficiency, installing hole is connected with oil groove, is convenient to when not using drill bit, and lubricating oil flows in installing hole by oil groove, drip on drill bit, drill bit maintained and safeguards, effectively extending its service life, reducing scrappage.
