Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with the accompanying drawings and implement
Example is described in further detail the utility model.It should be appreciated that specific embodiment described herein is only explaining this reality
With novel, it is not used to limit the utility model.
A kind of bearing race turning insert of the utility model, as shown in Figs. 1-2, the ontology 1 including being in polygon plate, this
Body 1 is made of cermet, and ontology 1 is enclosed by upper surface 2, lower surface 3 and connection upper surface 2 and multiple sides 4 of lower surface 3
Into, side 4 sets straight line portion 5 and arc sections 6 perpendicular to lower surface 3, upper surface 2 to lower recess, wherein, the radius of arc sections 6
For 1-5mm, straight line portion 5 is connected to form chip removal channel 7 with arc sections 6, enters chip removal channel from straight line portion 5 by the iron filings that turning is formed
7, which circumnutate, discharges after forming, increases chip removal ability, prevents iron filings from accumulating, for acute angle between straight line portion 5 and side 4, straight line portion 5 with
Angle between side 4 is 71-75 °, and at least one side 4 sets raceway blade 8 with straight line portion 5 and lower surface 3, and is rolling
The both sides setting sealing blade 9 of road blade 8.
In the present embodiment, sealing blade 9 can generate burr with 4 adjacent of side, influence turning accuracy, therefore, sealed knife
Transitional edges 10 are provided between sword 9 and the adjacent side 4, wherein, as shown in figure 3, transitional edges 10 include 11 He of Circular Nose Cutting Edge
Straight line sword 12, Circular Nose Cutting Edge 11 are connect with being sealed to people 9, and straight line sword is connect with side 4, can be effectively removed by 9 vehicle of sealing blade
The burr to be formed to be cut, makes Product Precision more preferable, the radius of Circular Nose Cutting Edge 11 is less than 1mm, and the length of straight line sword 12 is less than 2mm, and
The angle of the side 4 adjacent thereto of straight line sword 12 is 70-80 °.The positioning of upper surface 2 and lower surface 3 is provided through on ontology 1
Hole 13, location hole 13 are used to that blade to be mounted on knife rest 14 and it be fixed on the positioning, generally use fixed plate and knife rest
14 clamp, and blade has frictional force between knife rest 14 and fixed plate respectively, and displacement of blade is prevented by the frictional force, but
During use, if the power that blade is subject to is more than the frictional force, it would still be possible to will appear displacement of blade phenomenon, the utility model increases
Location hole is added to position, compared with fixed plate individually positions, location hole 13 carries out position restriction to blade, will not be because of processing stress
And 13 radial displacement of location hole occurs, additionally by fixed plate axial compression, ensure that the installation of blade is fixed, and enables the blade to jail
Solid be mounted on knife rest 14 on.
When the utility model is used, as illustrated in figures 4-5, Fig. 4 is illustrated that blade installation diagram, Fig. 5 is illustrated that use
Blade is arranged on knife rest 14 by state diagram, is adjusted relative position between blade and knife rest 14, is entered product to adjust blade
Angle, the included angle A between the side 4 of blade and vertical plane is 5-9 °, is adjusted according to different product, installation is complete for blade
Afterwards, knife rest 14 is close to product with cutting blade, and turning is carried out to product.
The beneficial effects of the utility model：
(1) by raceway blade with sealing blade be arranged on it is same improve turning accuracy on knife, reduce and be processed into
