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 allowance undercut plus
Work method.
Background technique
During processing other model cylinder of diesel engine, rise by blade processing method using mature production line special plane come real
Existing undercut processing, can preferably be guaranteed.DK cylinder body stop portion need to process 30 ° of oblique angle intracavity wedge angle undercuts, still
It is processed for DK cylinder body pilot stage, existing numerical control machining center cannot achieve knife processing of rising required for the special undercut of processing
Function, being processed using new fixture in special purpose machine tool influences production line production efficiency, while increasing experimental manufacturing cost, according to existing
Situation cannot achieve.
Summary of the invention
The existing above problem is processed in order to solve the special seam allowance undercut of DK cylinder body, the present invention provides a kind of DK cylinder bodies
The processing method of special seam allowance undercut.
Present invention technical solution used for the above purpose is: the processing side of the special seam allowance undercut of DK cylinder body
Method, comprising the following steps:
Step a: processing seam allowance undercut top half 2, selects the molding R0.8mm fillet for meeting angle requirement
Blade adjusts cutter diameter using tool setting gauge, its diameter is made to be less than seam allowance diameter, interpolation Milling Machining to desired empty knife diameter；
Step b: processing seam allowance undercut lower half portion 3, and selecting point of a knife fillet is the triangular blade of R0.8mm, benefit
Cutter diameter is adjusted with tool setting gauge, cutter orientation is cut with eccentric manner when processing, is reruned to cylinder holes center, is then led
Axis rotation, Z-direction feed process wedge angle undercut.
It is that 0.02mm locates interpolation and mills to requiring being higher than manufactured right angle seam allowance end face distance d in the step a
Empty knife diameter completes the processing of stop mouth of air cylinder body undercut top half 2.
In the step b, cutter diameter is adjusted to sky knife diameter dimension Φ 144.0mm on tool setting gauge, Z-direction when processing
Feed 0.25mm processes R0.8 wedge angle undercut, rollback cutter, orientation trouble, bias removal cutter, completion stop mouth of air cylinder body
The processing of undercut lower half portion 3.
The processing method of the special seam allowance undercut of DK cylinder body of the invention, using two cutters to the seam allowance undercut upper half
Divide and lower half portion is processed respectively, solve the technical problem in processing, realizes machining center main shaft and process special sky
The function of cutter groove, ensure that machining accuracy, improve processing efficiency.

Specific embodiment
DK cylinder body 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 that the cutter for the sharp corner that processing is higher than plane is lower than the cutter of plane sharp corner with processing.
Cutter use self-control cutter: (1) the molding R0.8 fillet blade that meets drawing angle requirement, and utilization pair are selected,
Knife instrument adjusts cutter diameter, its diameter is made to be less than seam allowance diameter, in order to avoid destroying seam allowance plane, utilizes interpolation milling method
It is being higher than at manufactured right angle seam allowance end face 0.02mm, it is empty to complete stop mouth of air cylinder body for interpolation milling to desired empty knife diameter
The processing of cutter groove top half 2.(2), point of a knife fillet is 60 degree of the triangular blade of R0.8mm, utilizes grinding wheel and diamond file
The blade that fillet is R0.8mm is grinding into the boring cutter with the suitable wedge angle of drawing requirement phase.Sharpening angle is by surveying on tool setting gauge
Cutting-tool angle and diameter are measured to guarantee.
The processing method of the special seam allowance undercut of DK cylinder body of the invention, work in-process will realize adding for special empty knife in the heart
Procedure of processing can be resolved into two steps and completed the process by work:
Step a: processing seam allowance undercut top half 2, selects the molding R0.8mm fillet for meeting angle requirement
Blade, and cutter diameter is adjusted using tool setting gauge, so that its diameter is less than seam allowance diameter and is being processed using interpolation milling method
When, it is at 0.02mm being higher than manufactured right angle seam allowance end face distance d, interpolation milling is arrived in order to avoid destroying seam allowance plane
It is required that empty knife diameter.The special seam allowance undercut top half processing of DK cylinder body is as shown in Figures 2 and 3.
Step b: processing seam allowance undercut lower half portion 3, and selecting point of a knife fillet is the triangular blade of R0.8mm, benefit
Cutter diameter is adjusted with tool setting gauge, cutter orientation is cut with eccentric manner when processing, is reruned to cylinder holes center, is then led
Axis rotation, Z-direction feed 0.25mm process R0.8mm wedge angle sky knife, and rollback cutter, orientation trouble is eccentric to remove cutter, in this way
Just process the undercut for meeting drawing requirement.The processing of DK cylinder body special seam allowance undercut lower half portion is as shown in Figure 4 and Figure 5.
If the triangular blade knife in step b is that the fillet blade in step a improves acquisition, development is as follows: above
Satisfactory fillet blade utilizes grinding wheel and diamond file reconditioning, and blade front end major part chisel edge is ground off, and 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 guarantees.
The present invention is described by embodiment, and those skilled in the art know, is not departing from spirit of the invention
In the case where range, various changes or equivalence replacement can be carried out to these features and embodiment.In addition, in religion of the invention
It leads down, can modify to these features and embodiment to adapt to particular situation and material without departing from essence of the invention
Mind and range.Therefore, the present invention is not limited to the particular embodiment disclosed, fallen with claims hereof
Embodiment in range belongs to protection scope of the present invention.
