Description
Technical field
It the utility model is related to the cutting tool field of industrial processes, and in particular to the T-shaped knife of Double-side rounding.
Background technology
Rose reamer is to be assemblied on the lathes such as milling machine, drilling machine, planer, beveler to fall for 60 degree or 90 degree of workpieces processing
Angle and taper hole, reverse mould corner angle cutter.Rose reamer is applied widely, is not only suitable for the chamfering of standard machinery workpiece, more suitable
Chamfering and the deburring of angle workpiece are baffled together in precision.
Rose reamer is typically all vertical processing, may be only available for the groove of part horizontal plane or the processing in hole, processes part
Clamping is needed again just to process when the groove of side.
Therefore need to design a kind of directly can carry out the rose reamer of chamfer machining to the groove of part side.
Goal of the invention of the present utility model is：For above-mentioned problem, there is provided one kind can be directly to part side
The groove in face carries out the T-shaped knife of Double-side rounding of chamfer machining.
The technical solution adopted in the utility model is such：The T-shaped knife of Double-side rounding, including handle of a knife and cutter head, its feature
It is：The handle of a knife is excessive to cutter head circular arc, and the cutter head is made up of multiple cutting seats, is provided between the adjacent cutting seat
Chip area, the cutting seat include rake face and rear knife face, and the rake face is crossed to form cutting edge, the cutting with rear knife face
Sword is made up of three line segments.
Three line segments described further are line segment a, line segment b and line segment c, and the angle of the line segment a and line segment b are 45o,
For line segment b parallel to handle of a knife axis, line segment c and line segment b angle is 45o。
Described multiple cutting seats are 4 cutting seats.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：Can be directly to part
The groove of side carries out chamfer machining；The chamfering of processing is highly polished, and processing efficiency greatly promotes.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model cutting blade structure schematic diagram.
Marked in figure：1 is handle of a knife, and 2 be chip area, and 3 be rake face, and 4 be rear knife face, and 5 be cutting edge, and 6 be line segment a, and 7 are
Line segment b, 8 be line segment c.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
As shown in Figure 1 and Figure 2, the T-shaped knife of Double-side rounding, including handle of a knife 1 and cutter head, the handle of a knife 1 is excessive to cutter head circular arc,
The cutter head is made up of multiple cutting seats, and chip area 2 is provided between the adjacent cutting seat, and the cutting seat includes rake face
3 and rear knife face 4, the rake face 3 is crossed to form cutting edge 5 with rear knife face 4, and the cutting edge 5 is made up of three line segments, and three
Bar line segment is line segment a6, line segment b7 and line segment c8, and the angle of the line segment a6 and line segment b7 are 45o, line segment b 7 is parallel to handle of a knife
1 axis, line segment c8 and line segment b7 angle is 45o。
