The DK cylinder body special rabbet clearance groove processing method adopts two tools to respectively process the upper half and the lower half of the rabbet clearance groove, solves the technical puzzle in processing, and enables the processing center spindle to achieve the function of processing special clearance grooves; the processing precision is guaranteed, and the processing efficiency is increased.
Description
Technical field
The present invention relates to cylinder of diesel engine technical field, more particularly to a kind of cylinder of diesel engine cylinder body seam undercut plus
Work method.
Background technology
During other model cylinder of diesel engine are processed, rise by blade processing method come real using ripe production line special plane
Existing undercut processing, can preferably be ensured.DK cylinder bodies stop portion need to process 30 ° of oblique angle intracavity wedge angle undercuts, but
For the processing of DK cylinder bodies advanced development, existing numerical control machining center cannot realize the knife processing of rising processed required for special undercut
Function, production line production efficiency is affected using new fixture in special purpose machine tool processing, while increase experimental manufacturing cost, according to existing
Situation cannot be realized.
The content of the invention
In order to solve the problems referred to above that the special seam undercut processing of DK cylinder bodies is present, the invention provides a kind of DK cylinder bodies
The processing method of special seam undercut.
The technical scheme that adopted for achieving the above object of the present invention is：The processing side of the special seam undercut of DK cylinder bodies
Method, comprises the following steps：
Step a：Seam undercut top half 2 is processed, from the shaping R0.8mm fillet blades for meeting angle requirement,
Tool diameter is adjusted using tool setting gauge so as to which diameter is less than seam diameter, and interpolation Milling Machining is to desired empty knife diameter；
Step b：Seam undercut the latter half 3 is processed, from the triangular blade that point of a knife fillet is R0.8mm, using right
Knife instrument adjusts tool diameter, plus man-hour cutter is oriented with knife under eccentric manner, reruns to cylinder holes center, then main shaft rotation
Turn, Z-direction feed processes wedge angle undercut.
In step a, higher than manufactured right angle seam end face distance d be at 0.02mm interpolation milling to requiring
Empty knife diameter, completes the processing of stop mouth of air cylinder body undercut top half 2.
In step b, tool diameter is adjusted to sky knife diameter dimension Φ 144.0mm, plus man-hour Z-direction on tool setting gauge
Feed 0.25mm processes R0.8 wedge angle undercuts, and rollback cutter, orientation trouble, bias removes cutter, completes stop mouth of air cylinder body
The processing of undercut the latter half 3.
The processing method of the special seam undercut of DK cylinder bodies of the present invention, using two cutters to the seam undercut first half
Divide and the latter half is processed respectively, solve the technical barrier in processing, make machining center main shaft realize the special sky of processing
The function of cutter groove, it is ensured that machining accuracy, improves working (machining) efficiency.

Specific embodiment
DK cylinder bodies stop portion need to process 30 ° of oblique angle intracavity wedge angle undercuts 1, as shown in figure 1, using two kinds of cutters, point
It is not processing higher than the cutter of the sharp corner of plane and processes the cutter less than plane sharp corner.
Cutter is using self-control cutter：（1）, from meeting the shaping R0.8 fillet blades of drawing angle requirement, and using right
Knife instrument adjusts tool diameter so as to which diameter is less than seam diameter, in order to avoid destroying seam plane, using interpolation milling method
Higher than at manufactured right angle seam end face 0.02mm, interpolation milling completes stop mouth of air cylinder body empty to desired empty knife diameter
The processing of cutter groove top half 2.（2）, point of a knife fillet be 60 degree of R0.8mm of triangular blade, using emery wheel and diamond file
Fillet is grinding into into the boring cutter with the suitable wedge angle of drawing requirement phase for the blade of R0.8mm.Sharpening angle is by surveying on tool setting gauge
Measure cutting-tool angle and diameter to ensure.
The processing method of the special seam undercut of DK cylinder bodies of the present invention, work in-process will realize in the heart adding for special empty knife
Work, can resolve into procedure of processing two steps and machine：
Step a：Seam undercut top half 2 is processed, from the shaping R0.8mm fillet blades for meeting angle requirement,
And adjusting tool diameter using tool setting gauge so as to diameter is less than seam diameter, using interpolation milling method, is adding man-hour, is
Seam plane is avoided damage to, at higher than manufactured right angle seam end face distance d for 0.02mm, interpolation milling is to requiring
Empty knife diameter.The special seam undercut top half of DK cylinder bodies is processed as shown in Figures 2 and 3.
Step b：Seam undercut the latter half 3 is processed, from the triangular blade that point of a knife fillet is R0.8mm, profit
Tool diameter is adjusted with tool setting gauge, plus man-hour cutter is oriented with knife under eccentric manner, is reruned to cylinder holes center, Ran Houzhu
Axle rotates, and Z-direction feed 0.25mm processes R0.8mm wedge angles sky knife, and rollback cutter, orientation trouble, bias removes cutter, so
Just process the undercut for meeting drawing requirement.The special seam undercut the latter half of DK cylinder bodies processes as shown in Figure 4 and Figure 5.
If the triangular blade knife in step b is the fillet blade in step a improves acquisition, development is as follows：Above
Satisfactory fillet blade is ground off blade front end major part chisel edge using emery wheel and diamond file reconditioning, only retains circle
Angle part, and fillet with grind off after end face transition at an appropriate angle, the wedge angle blade of proper angle is eventually formed, right
Diameter is adjusted to sky knife diameter dimension Φ 144.0mm on knife instrument.Sharpening angle be by tool setting gauge measure cutting-tool angle and
Diameter is ensureing.
The present invention is described by embodiment, and those skilled in the art know, in the spirit without departing from the present invention
In the case of scope, various changes or equivalence replacement can be carried out to these features and embodiment.In addition, in the religion of the present invention
Lead down, these features and embodiment can be modified to adapt to the essence of particular situation and material without departing from the present invention
God and scope.Therefore, the present invention is not limited to the particular embodiment disclosed, and falls with claims hereof
In the range of embodiment belong to protection scope of the present invention.
