Description
Technical field
It the utility model is related to cutter field, and in particular to a kind of lathe tool that can quickly cool down.
Background technology
Lathe tool is the cutter for turnery processing, with a cutting tip.Lathe tool is most widely used in machining
One of cutter.Lathe tool durability is always an important factor for weighing lathe tool quality.In the prior art, many feelings of the fracture of lathe tool
It is due to that cooling is not in place caused under condition, lathe tool is in turning process, cutting edge and object severe friction, local temperature rise,
Cutter hub, which becomes fragile, to be just easily broken, it is therefore desirable to a kind of lathe tool that can quickly cool down.
Utility model content
Above-mentioned to solve the problems, such as, the utility model provides a kind of lathe tool that can quickly cool down.
The technical solution of the utility model is：A kind of lathe tool that can quickly cool down, including cutter head and knife bar, the knife are provided
Club head is equipped with the sinking step for being used for installing the cutter head, and the sinking step center is equipped with mounting hole, the cutter head center
Equipped with threaded hole, the cutter head is fixed to the sinking step by sequentially passing through the screw of the threaded hole and the mounting hole
On, when the cutter head is fixed on the knife bar, the outer contour of the cutter head is bonded with the Internal periphery of the sinking step, described
Cutter head both ends are equipped with the centrosymmetric point of a knife of the threaded hole, and the outer contour of the cutter head is on the threaded hole center pair
Claim, the Internal periphery of the sinking step is equipped with curved coolant water conservancy diversion on the mounting hole central symmetry, the knife bar
Groove.
Preferably, coolant diversion trench one end notch is connected with the sinking step.
Preferably, the diversion trench includes major trough and branch groove, the branch groove be evenly distributed on the both sides of the major trough and with
The major trough communicates.
Preferably, diversion trench longitudinal cross-section profile is arc-shaped.
Preferably, the angle of the point of a knife and the cutter head is 90 °.
Preferably, the cutter head and the arbor surface scribble erosion shield.
The beneficial effects of the utility model are：
1. cutter head both ends are equipped with and two-sided can be used on the centrosymmetric point of a knife of threaded hole, same cutter head, knife is improved
Head utilization rate.
2. directly cutter head will not be processed at the top of knife bar, do not have to integral replacing when cutter head damages so, save metal material
Expect, the cutter head of different hardness can be also installed on same knife bar, it is economical and practical.
3. arbor surface is equipped with coolant diversion trench so that coolant contacts fully with knife bar, improves heat exchanger effectiveness, soon
Fast cooling turning tool.
Brief description of the drawings
Fig. 1 is a kind of lathe cutter structure schematic diagram that can quickly cool down of the utility model.
Embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only explaining this
Utility model, is not used to limit the utility model.
As shown in Figure 1, the utility model provides a kind of lathe tool that can quickly cool down, including cutter head 2 and knife bar 1, the knife
1 head of bar, which is equipped with, is used to installing the sinking step of the cutter head 2, and the sinking step center is equipped with mounting hole, in the cutter head 2
The heart is equipped with threaded hole, and the cutter head 2 is fixed to the sinking by sequentially passing through the screw 4 of the threaded hole and the mounting hole
On step, when the cutter head 2 is fixed on the knife bar 1, the outer contour of the cutter head 2 and the Internal periphery of the sinking step paste
Close, 2 both ends of cutter head are equipped with the centrosymmetric point of a knife 3 of the threaded hole, and the outer contour of the cutter head 2 is on the spiral shell
Pit central symmetry, the Internal periphery of the sinking step is equipped with curved on the mounting hole central symmetry, the knife bar 1
Coolant diversion trench.
In the utility model, coolant diversion trench one end notch is connected with the sinking step.
In the utility model, the diversion trench includes major trough 6 and branch groove 5, and the branch groove 5 is evenly distributed on the major trough 6
Both sides and communicated with the major trough 6.
In the utility model, diversion trench longitudinal cross-section profile is arc-shaped.
In the utility model, the angle of the point of a knife 3 and the cutter head 2 is 90 °.
In the utility model, the cutter head 2 and 1 surface of the knife bar scribble erosion shield.
When lathe tool works, coolant endlessly flows into diversion trench, drives coolant and knife bar 1 abundant by diversion trench
Contact, takes away heat, quick cooling.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Any modification, equivalent substitution or improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
