Abstract
The present invention discloses a kind of Combined turning tool of machining, including screw, blade, knife bar and cutter head, the cutter head is made as one with knife bar, the blade has two, two blades are arranged in juxtaposition, and are fixed by screws on cutter head, and the point of a knife angle, θ of two blades is 55 ° ± 1 °, it is 30 ° ± 1 ° to process tool cutting edge angle Kr', and two blades have difference in height h between being generally aligned in the same plane interior and two points of a knife.The present invention being capable of highly-efficient processing automobile gearbox pump cover body class thin-walled parts and guarantee crudy.
Description
Technical field
The present invention relates to a kind of cutter of machining.
Background technology
In auto parts and components processing, the higher thin-walled parts of some poor rigidities, required precision are frequently present of, wherein many
Number is the critical component of product, as the interrupted turning of end face of certain gearbox pump cover body is serious, wall thickness is relatively thin（Wall thickness<8mm）Machine adds
Chinese musical scale cun and position degree require higher, all the time as the problem for perplexing such pump cover body part processing.
At present, such pump cover body end face processing is main by numerically controlled lathe combination Special lathe clamp, passes through programme-control
Divided 2~3 times using universal cutter and machined.Because part is the interrupted turning of thin-walled, there is long processing time, expense cost height,
Crudy and relative position degree be difficult ensure etc. defect.
The content of the invention
Being capable of highly-efficient processing automobile gearbox pump cover body class thin-walled parts and guarantor object of the present invention is to provide one kind
Demonstrate,prove the Combined turning tool of crudy.
In order to achieve the above object, a kind of Combined turning tool of the invention, including screw, blade, knife bar and cutter head, it is described
Cutter head is made as one with knife bar, and the blade has two, and two blades are arranged in juxtaposition, and are fixed by screws on cutter head, two
The point of a knife angle, θ of individual blade is 55 ° ± 1 °, and processing tool cutting edge angle Kr' is 30 ° ± 1 °, and two blades are generally aligned in the same plane interior
And there is difference in height h between two points of a knife.
Difference in height h between the point of a knife of described two blades is in 0.1~1mm.
After said structure, the present invention be arranged in juxtaposition by two blades, two blades be generally aligned in the same plane in and two
There is difference in height between individual point of a knife, automobile gearbox pump cover body class thin-walled parts end face Roughing and fine machining can be made once to complete,
While ensure that crudy, part processing efficiency is also improved.In addition, the processing tool cutting edge angle Kr' of blade reduces energy
Tool life is enough improved, radiating is preferable, is conducive to tool life.
Brief description of the drawings
The present invention is further detailed explanation for the embodiment provided below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the Combined turning tool of the present invention；
Fig. 2 is Fig. 1 left view.
Embodiment
As shown in Figure 1, 2, a kind of Combined turning tool of the invention, including screw 1, blade 2, knife bar 3 and cutter head 4, it is described
Cutter head 4 is made as one with knife bar 3, and the blade 2 has two, and two blades 2 are arranged in juxtaposition, and are fixed on cutter head 4 by screw 1
On, the point of a knife angle, θ of two blades 2 is 55 ° ± 1 °, and processing tool cutting edge angle Kr' is 30 ° ± 1 °, and two blades 2 are located at same
There is difference in height h in plane and between two points of a knife.
As shown in Figure 1, 2, the difference in height h between the point of a knife of described two blades 2 is in 0.1~1mm.
The model of blade 2 in the present invention is chosen as：DCMT11T304.The blade of this model can increase the diameter of screw, carry
Itself high rigidity, improving the washability of lathe tool also reduces lathe tool cost.Blade 2 can bore product from domestic strain, also may be used
With the KYOCERA from import, Hitachi product.30 ° ± 1 ° of the processing tool cutting edge angle Kr'=of blade 2, this angle is in order to which lathe tool is in processing
During give the small downward power of part one, eliminate because of the oscillation phenomenon that part to be processed rigidity is not enough and produces.Two knives
There is difference in height h in piece 2 is generally aligned in the same plane and between two points of a knife, the allowance of blade 2 can be made to remain at one
In the fixed range of work.
