Abstract
The utility model relates to a combined inner-blade molded milling cutter which comprises a cutter body provided with a central hole. A plurality of cutter grooves which are arranged at equal distance along the periphery of the cutter body are arranged on one end face of the cutter body. Groove walls of one side of the cutter grooves are base lines which penetrate through the center of the central hole of the cutter body. The inclined angle alpha of the base lines of two adjacent cutter grooves is 60 degrees. A blade is detachably arranged in each cutter groove respectively and the cutting edge of each blade respectively extends out of the cutter groove and is arranged in the central hole of the cutter body. The molded milling cutter disclosed by the utility model can ensure the processing effect of workpieces and meet the processing requirement of workpieces. In addition, the cutter sharpening of the blades is simple and convenient, the manufacturing cost of cutters is saved and the universality is strong.
Description
Technical field
The utility model relates to a kind of milling cutter, particularly a kind of combined type inner edge profile milling cutter.
Background technology
Milling cutter for Milling Process, have the rotary cutter of one or more cutters tooth, cut the surplus of workpiece during its work successively off and on by each cutter tooth, to realize Milling Process.At present, usually adopt monoblock type Intranet sword profile milling cutter (as shown in Figure 5) to carry out Milling Process for shaft-like workpiece, but because cutter hub 1 ' and the cutter tooth 5 of this milling cutter are formed in one, add man-hour at the eccentric grove to the close end of workpiece, often processing effect is relatively poor, can not satisfy the processing request of workpiece, the sharpening difficulty of while cutter tooth 5, waste greatly, the product rejection rate height has increased the cost of manufacture of cutter.In addition, because cutter hub and cutter tooth are formed in one, it can not be adjusted according to the actual size of work piece, versatility is poor.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of combined type inner edge profile milling cutter is provided, and it not only can guarantee the processing effect of workpiece, satisfy the processing request of workpiece, and Sharpening a knife blade is simple, convenient, the cost of manufacture of having saved cutter, highly versatile.
The technical solution of the utility model is: a kind of combined type inner edge profile milling cutter, comprise the cutter hub with centre bore, one end face of described cutter hub is provided with a plurality of cutter grooves of circumferentially equidistantly arranging along cutter hub, one side channel wall of described cutter groove was the baseline at cutter hub centre bore center, angle α between the baseline of adjacent two cutter grooves is 60 °, dismountable blade that is equipped with respectively in each cutter groove, the blade of each blade stretches out the centre bore that the cutter groove is arranged in cutter hub outward respectively.
Described blade is installed in the cutter groove by screw is dismountable.
The bottom land of described cutter groove is provided with the installing hole that passes for screw, and described blade is provided with the bar hole that passes for screw.
The blade of each blade is all towards same direction.
Adopt technique scheme: because an end face of described cutter hub is provided with a plurality of cutter grooves of circumferentially equidistantly arranging along cutter hub, one side channel wall of described cutter groove was the baseline at cutter hub centre bore center, angle α between the baseline of adjacent two cutter grooves is 60 °, dismountable blade that is equipped with respectively in each cutter groove, the blade of each blade stretches out the centre bore that the cutter groove is arranged in cutter hub outward respectively, not only can guarantee the processing effect of workpiece like this, satisfy the processing request of workpiece, and Sharpening a knife blade is simple, convenient, saved the cost of manufacture of cutter, simultaneously, when the actual size of workpiece changes, only need blade to adjust and get final product highly versatile.
Because described blade is installed in the cutter groove by screw is dismountable, the bottom land of described cutter groove is provided with the installing hole that passes for screw, described blade is provided with the bar hole that passes for screw, not only is convenient to installation and removal, and can adjust the installation site of blade by the bar hole on the blade.

The specific embodiment
Referring to Fig. 1 to Fig. 4, a kind of embodiment of combined type inner edge profile milling cutter, this milling cutter comprise the cutter hub 1 with centre bore 1a, and the cutter hub 1 of present embodiment is disc, are used for working shaft-like workpiece.One end face of described cutter hub 1 is provided with a plurality of cutter grooves 2 of circumferentially equidistantly arranging along cutter hub 1, be used for installing blade 3, cutter groove 2 is provided with six in the present embodiment, one side channel wall of described cutter groove 2 was the baseline 2a at cutter hub centre bore 1a center, angle α between the baseline 2a of adjacent two cutter grooves is 60 °, dismountable blade 3 that is equipped with respectively in each cutter groove 2, described blade 3 is by screw 4 dismountable being installed in the cutter groove 2, the bottom land of described cutter groove 2 is provided with the installing hole 2b that passes for screw 4, described blade 3 is provided with the bar hole 3b that passes for screw 4, the bottom land of cutter groove 2 axially is provided with two installing hole 2b side by side along cutter groove 2 in the present embodiment, screw 4 adopts soket head cap screw, and screw 4 is two, blade 3 is fixed in the cutter groove 2 by two screws 4, not only be convenient to installation and removal, and can adjust the installation site of blade 3 by the bar hole 3b on the blade 3.Because blade 3 adopts with cutter groove 2 and removably connects, make blade 3 sharpenings simple, convenient, the cost of manufacture of having saved cutter.The blade 3a of each blade stretches out the cutter groove 2 outer centre bore 1a that are arranged in cutter hub respectively, and the blade 3a of each blade can enough guarantee the processing effect of workpiece all towards same direction in the present embodiment, satisfies the processing request of workpiece.
Above embodiment preferred embodiment is described the utility model; be not that scope of the present utility model is limited; relate under the prerequisite of spirit not breaking away from the utility model, various distortion that those of ordinary skill in the art makes the technical solution of the utility model and improving all fall in the protection domain that claim of the present utility model determines.
