Technical field
The utility model relates to the processing of oil injector seat phase perforation, and in particular to a kind of deburring of oil injector seat phase perforation
Cutter.
Background technique
Oil injector seat is an oil spout part in vehicle fuel conveying stocking system, annual in automobile production industry
Yield it is very big.
The production stage of oil injector seat is as follows at present: 1) Che Yiduan;2) the vehicle other end;3) 3.9 holes are bored;4) milling arc surface bores
Hole;5) ultrasonic cleaning;6) ECM deburring;7) ultrasonic cleaning;8) it packs.Wherein the bottleneck of ECM debarring process is,
It is limited by machined material and processing technology, causes oil injector seat and the burr of fuel injector junction that cannot effectively be gone by ECM
It removes, main cause is that remaining burr is not of uniform size on the point for go at step 4 flash removed, directly results in ECM removal
The effect disunity of burr,
If cannot adequately guarantee the burr remaining balance at phase perforation in process, rear ECM processing will be allowed to
Process becomes and its unstable, cannot control product quality well.
Make a concrete analysis of in view of the above problems, if wanting to reach point-to-point deburring treatment effect, it is necessary to have 2 it is prerequisite
Condition: 1, in order to avoid mismachining tolerance caused by resetting, cutter must have complete " spindle " shape of simultaneous processing and mutually pass through wheel
The condition of profile;2, lathe must be provided simultaneously with the function of three-shaft linkage.Since existing lathe itself all has three-shaft linkage
Basic function, then one is exactly the key for solving the problems, such as this cutter with more free angles.
In conclusion needing a kind of cutter for enough reaching point-to-point burr processing at present, make not make the fuel injector before ECM
Burr state reaches consistent at seat phase perforation.

The deburrer in hole, including knife handle and bulb rose reamer, the bulb rose reamer are integrally connected to one end of the knife handle, institute
State that knife handle is cylindrical, the bulb rose reamer includes the knife head ball of two panels halfround bar slice shape, knife head ball described in two panels about
The rotary shaft of the knife handle axisymmetricly arranges that knife head ball described in two panels on the vertical section of the knife handle mutually dock by one
And be arranged in a circular formation, the thickness of knife head ball described in two panels is gradually reduced from the inside to the outside on radially of the axis of rotation, and at two
The main cutting edge of semicircular arc is respectively formed at the maximum outer circle of the knife head ball, on radially of the axis of rotation, the master is cut
Two side knife surfaces for cutting sword are respectively formed relief angle and anterior angle, and on radially of the axis of rotation, and two anterior angles are straight line and company
Line passes through axis of rotation, and two relief angles are axisymmetricly arranged in camber line and about rotary shaft, along each knife head ball
The anterior angle and the integrated intersection of another knife head ball offer a chip pocket respectively, the chip pocket one
It extends on the knife handle, the chip pocket is vertical with the anterior angle.
In the above scheme, the main cutting edge by the knife handle to the knife head ball be respectively rear end cutting edge,
Middle part cutting edge and front end cutting edge.
In the above scheme, the width of the chip pocket is gradually reduced by the knife head ball to the knife handle.
In the above scheme, on radially of the axis of rotation, the curvature of two relief angles is less than where the knife head ball
Round curvature.
In the above scheme, intersecting lens of the chip pocket on the knife handle is arc.
The utility model, it is simple and practical in structure, it is low in cost, can complete " spindle " shape of time processing mutually pass through contour line, keep away
Mismachining tolerance caused by resetting is exempted from, the product burr state before capable of making not being ECM reaches requirement, to guarantee
The consistency of product size, is substantially improved product qualification rate after ECM.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawings of the specification.
The utility model discloses a kind of deburrer of oil injector seat phase perforation, those skilled in the art can be used for reference
Present disclosure is suitably modified realization of process parameters.It is important to note that all similar substitutions and modifications are to this field skill
It is it will be apparent that they are considered as being included in the utility model for art personnel, and related personnel can obviously not take off
From being modified on the basis of the content of the present invention, spirit and scope to content described herein or appropriate changes and combinations, come
Implementation and application the utility model technology.
In utility model, unless otherwise stated, Science and Technology noun used herein has this field skill
The normally understood meaning of art personnel institute.
As shown in Figures 1 to 5, the deburrer of a kind of oil injector seat phase perforation provided by the utility model, including knife
Handle 1 and bulb rose reamer, bulb rose reamer are integrally connected to one end of knife handle 1, and knife handle 1 is cylindrical, and bulb rose reamer includes
The knife head ball 6 of two panels halfround bar slice shape, two panels knife head ball 6 axisymmetricly arrange about the rotary shaft of knife handle 1, two panels spherical shape knife
First 6 mutually integrally dock and are arranged in a circular formation on the vertical section of knife handle 1,
The thickness of two panels knife head ball 6 is gradually reduced from the inside to the outside on radially of the axis of rotation, and in two knife head balls 6
The main cutting edge 2 of semicircular arc is respectively formed at the maximum outer circle at place, main cutting edge 2 is respectively by knife handle 1 to knife head ball 6
Rear end cutting edge 7, middle part cutting edge 8 and front end cutting edge 9, in corresponding diagram 5, the region a of intersection in part model 10
For cutter rear end working position, the chamfer dimesion region 0.02-0.1, b is working position in the middle part of cutter, and chamfer dimesion is
The region 0.02-0.1, c is cutter front end portion working position, chamfer dimesion 0.02-0.1, rear end cutting edge 7, middle part cutting
Sword 8 and front end cutting edge 9 are respectively used to the burr of the intersection at machining different location, make the burr at phase perforation both ends
It perfect can remove, point (cutter) can be reached to point (product) burr processing requirement.
On radially of the axis of rotation, two side knife surfaces of main cutting edge 2 are respectively formed relief angle 3 and anterior angle 4, and in rotary shaft
Radially, two anterior angles 4 are straight line and line passes through axis of rotation, and two relief angles 3 are in axis pair in camber line and about rotary shaft
Claim arrangement, the design of this multi-angle cutting edge can effectively remove the burr remaining balance at phase perforation, the ECM processing after being allowed to
Process becomes more stable, and controls product quality well.
A chip pocket 5, chip pocket 5 are offered respectively along each anterior angle 4 and the integrated intersection of another knife head ball 6
It integrally extending on knife handle 1, chip pocket 5 is vertical with anterior angle 4, and the width of chip pocket 5 is gradually reduced by knife head ball 6 to knife handle 1,
Clast water conservancy diversion can be discharged in this way, prevent clast from remaining.
On radially of the axis of rotation, the curvature of two relief angles 3 is less than the curvature of circle where knife head ball 6, in this way in knife handle 1
When rotation, make that there is different cutting angles between relief angle 3 and anterior angle 4, it is easier to remove the burr on each position of intersection.
Intersecting lens of the chip pocket 5 on knife handle 1 is arc, is convenient for streamlined discharge, to reduce clast to deburring
The influence of process.
The utility model, it is simple and practical in structure, it is low in cost, can complete " spindle " shape of time processing mutually pass through contour line, keep away
Mismachining tolerance caused by resetting is exempted from, the product burr state before capable of making not being ECM reaches requirement, to guarantee
