Abstract
The thick floating double-blade boring cutter of a kind of lathe strength, includes cylinder handle of a knife (1), is installed on handle of a knife front end and passes radially through square-section strip double edge cutter (2) of handle of a knife, radially mounted coolant conveying pipe (3) in handle of a knife surface；Described cutter head (2) have be symmetrically positioned in two main cutting edges (2a) on handle of a knife both sides, two the termination front cutting edges (2b) perpendicular with main cutting edge, respectively be opened in the other chip curling groove (2c) of the upper main cutting edge of both sides rake face (2e), respectively be opened in main after on knife face (2f) two vertical with chip curling groove (2c) communicate chip dividing groove (2d), main after knife face (2f) and minor flank (2g) junction formation front cutting edge (2b).This utility model dynamic balance performance is good, machining accuracy is high and can quickly disconnect chip, is suitable for the lathe of various model and the deep hole big cutting output roughing of boring machine.
Description
Technical field
This utility model belongs to boring cutter technical field.
Background technology
Hole type parts is through processing frequently with lathe tool, and tradition lathe tool is the most all to use single-blade structure, the lathe tool of this structure
Working (machining) efficiency ratio is relatively low, and edge turning tool dynamic balance performance is bad, can affect machining accuracy, particularly cut greatly at roughing deep hole
During the amount of cutting, performance is substantially.Additionally, conventional boring cutter does not the most divide cuts sword, the chip processed will not quickly disconnect, and impact adds
The surface roughness of work workpiece.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, it is provided that a kind of dynamic balance performance is good, machining accuracy is high,
And can quickly disconnect the lathe being suitable for various model of chip and the deep hole rough machined strength of big cutting output slightly floating pair of boring machine
Sword boring cutter.
The purpose of this utility model is achieved through the following technical solutions:
The thick floating double-blade boring cutter of a kind of lathe strength, includes cylinder handle of a knife, is installed on handle of a knife front end and passes radially through
The square-section strip double edge cutter of handle of a knife, the radially mounted coolant conveying pipe in handle of a knife surface；Described cutter head has
It is symmetrically positioned in two main cutting edges on handle of a knife both sides, two the termination front cutting edges perpendicular with main cutting edge, is opened in respectively
Chip curling groove that on the rake face of both sides, main cutting edge is other, respectively be opened in main after on knife face two vertical with chip curling groove communicate divide
After bits groove, master, knife face forms front cutting edge with minor flank junction.
The main cutting edge at this utility model cutter head two ends is symmetrically positioned in handle of a knife both sides, adds whole system dynamic balance in man-hour and obtains
To greatly improving, stable working is good, and machining accuracy can be greatly improved.During work, two terminal knife edges carry out boring processing simultaneously, add
Work speed is fast, drastically increases working (machining) efficiency.The chip curling groove offered on cutter head and chip dividing groove can quickly disconnect chip, carry
The surface quality of high processing workpiece.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of this utility model cutter head.
Detailed description of the invention
The thick floating double-blade boring cutter of lathe strength as shown in Figure 1 and Figure 2, includes cylinder handle of a knife 1, is installed on handle of a knife front end
And pass radially through the square-section strip double edge cutter 2 of handle of a knife, the radially mounted coolant conveying pipe in handle of a knife surface
3.Described cutter head 2 has perpendicular with main cutting edge for two main cutting edge 2a two the termination pair being symmetrically positioned in handle of a knife both sides
Cutting edge 2b, respectively be opened in the other chip curling groove 2c of main cutting edge on the rake face 2e of both sides, respectively be opened in main after on knife face 2f
Two vertical with chip curling groove 2c communicate chip dividing groove 2d, main after knife face 2f form front cutting edge with minor flank 2g junction
2b。
Main cutting edge 2a of the present utility model is used for axial machining, and front cutting edge 2b acts primarily as balance and guides work
With, chip curling groove 2c acts primarily as increase anterior angle and reduces cutting force and the effect of volume bits, and chip dividing groove 2d is used for quickly disconnecting chip, improves
The surface quality of processing workpiece.
Claims (1)
1. the thick floating double-blade boring cutter of lathe strength, it is characterised in that include cylinder handle of a knife (1), be installed on handle of a knife front end
And pass radially through square-section strip double edge cutter (2) of handle of a knife, the radially mounted coolant conveying in handle of a knife surface
Pipe (3)；Described cutter head (2) has be symmetrically positioned in that two main cutting edges (2a) on handle of a knife both sides are perpendicular with main cutting edge two
Individual termination front cutting edge (2b), it is opened in the other chip curling groove (2c) of the upper main cutting edge of both sides rake face (2e) respectively, offers respectively
After master two on knife face (2f) vertical with chip curling groove (2c) communicate chip dividing groove (2d), main after knife face (2f) and minor flank
(2g) junction forms front cutting edge (2b).
