Specific embodiment
Embodiment of the present utility model is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages of the present utility model and effect easily.
As shown in Figure 1-Figure 3, a kind of composite milling cutter, including cutter hub 1, is provided with least one for product on cutter hub 1
The endoporus of the conical surface carries out the face milling knife piece 4 that the chamfering blade 3, at least two of chamfer machining is used for being processed the product conical surface,
The blade of face milling knife piece 4 linearly and the edge line perpendicular to cutter hub 1 center line, the edge line of all face milling knife pieces 4 locates
In same plane so that the blade of all face milling knife pieces 4 is processed to same plane, promote stress balance, effectively reduce and shake
Dynamic, in the present embodiment, the blade of chamfering blade 3 is linearly and the edge line is 45 ° with the center line angle of cutter hub 1, should
Angle can also be arranged as required to as other angles.The quantity of face milling knife piece 4 can be for two, three, four or more,
The quantity of face milling knife piece 4 is more, and structure is more stable, is more conducive to reducing vibration, but need to consider whether the installing space of cutter hub 1 fills
Foot, therefore, the quantity of face milling knife piece 4 is preferably two.Face milling knife piece 4 is realized being processed the product conical surface, chamfering blade 3
Realize carrying out the endoporus of product chamfer machining, milling face and chamfering are carried out simultaneously, and production efficiency is high.
In the present embodiment, the quantity of face milling knife piece 4 is two, and the front milling cutter face 41 of two face milling knife pieces 4 is in same flat
On face and the plane through cutter hub 1 center line, two face milling knife pieces 4 are located at the both sides of plane respectively, two face milling knife pieces 4
Blade is symmetrical relative to the center line of cutter hub 1, and the straight length that the blade the outer end point of two face milling knife pieces 4 is formed is little more than connecting rod
Head bore blank outside diameter, for example, in the present embodiment, little head bore blank outside diameter to be processed is in 47-48mm, then, milling
The straight length that the blade the outer end point of face blade 4 is formed is that the maximum gauge formed when 58mm, i.e. face milling knife piece 4 rotate is
58mm so that the blade of face milling knife piece 4 exceedes the length stress of half, and the blade of two face milling knife pieces 4 is relative to cutter hub 1
Center line symmetrical, it is ensured that the stationarity of face milling knife piece 4 during processing, it is ensured that the surface quality of the product being milled, it is to avoid list
The vibration that sword occurs when processing, and improve cutting-tool's used life.
There is intersection point in the plane of the edge line place straight line of chamfering blade 3 and two rotation formation of face milling knife piece 4, the intersection point
To 1 center line of cutter hub vertical range according to the size of processed product depending on, in the present embodiment, due to be processing endoporus fall
Angle, therefore, the vertical range of the intersection point to 1 center line of cutter hub rotates to be formed less than two face milling knife pieces 4 around the center line of cutter hub 1
Circle radius.
Cutter holder 2 is installed on cutter hub 1, chamfering blade 3 is on cutter holder 2.The center line of cutter hub 1 is through chamfering blade 3
31 place plane of rake face, improve stability of the chamfering blade 3 in chamfer machining.The cutting blade of chamfering blade 3 is to cutter hub 1
The vertical range of center line is close to the radius of processed product endoporus, according to chamfering need its accurate location is set.
7 outer surface of installation portion of cutter hub 1 is provided with inclined plane 8.The quantity of inclined plane 8 be two, three or more, the inclination
Face 8 is indent inclined-plane, and the inclined-plane is gradually lowered that (active side refers to the side is processed by product, separately towards the active side of cutter hub 1
Side is then installation side, in machine spindle), the inclined-plane is at a certain angle with the center line shape of cutter hub 1, cutter hub 1 and
Connected with side-strengthened between machine spindle, be prevented effectively from cutter hub 1 and slip from machine spindle.
Offer on cutter hub 1 for installing the first mounting groove 5 of face milling knife piece 4, face milling knife piece 4 first is installed installed in this
On groove 5；Offer on cutter hub 1 for installing the second mounting groove 6 of chamfering blade 3, cutter holder 2 on the second mounting groove 6, if
Put mounting groove so that the structure of milling cutter is more consolidated, and also allows for chip removal.Shape between the side wall of face milling knife piece 4 and the first mounting groove 5
Into chip area 9 so that the iron filings produced in working angles smoothly can be discharged.
In the present embodiment, the production code member of cutter hub 1 is TEP32-A45D58 × 70, and the production code member of cutter holder 2 is
SCSPR08CA-06, the production code member of chamfering blade 3 is CPMT060204, and the production code member of face milling knife piece 4 is TCMT16T308.
