Abstract

The utility model discloses a PXE piston processing milling cutter, including the handle of a knife, the handle of a knife on be equipped with the tool bit, the circumference of tool bit on the equipartition have three cutting face, the plane at three cutting face place all passes through the centre of a circle of tool bit, just is being equipped with bow-shaped chip groove to cutting the face, and the face of cutting is perpendicular with the plane of chip groove in the tool bit upper end, the epitaxy of cutting face extend to the circumference of tool bit and form the cutting edge outward, handle of a knife length be 45mm, the length of tool bit is 35mm, the diameter of tool bit is 9mm, tool bit and handle of a knife pass through the chamfer transition, the radius that contains the cutting edge of tool bit is 5mm, the length of cutting edge be 24. The length of the cutting edge covers the axial length of the outer circle of the PXE piston, so that the cutting edge can be molded at one time. Meanwhile, reasonable length and diameter are designed, and the extending plane of the cutting surface directly passes through the axis of the cutter, so that the cutter has good rigidity and toughness at high rotating speed, the processing efficiency is greatly improved, and the service life is greatly prolonged.

Description

PXE piston machining milling cutter

Technical Field

The utility model relates to a machining's milling cutter, especially a PXE piston processing milling cutter.

Background

In the prior art, the machining of the PXE piston is a single part machining mode, namely, only one workpiece is machined at a time, and a corresponding cavity is milled by using a common milling cutter. However, for large-scale processing, the method is slow and the parts are poor in uniqueness, and the shapes of cavities milled in each workpiece are slightly different, so that the quality of products is uneven. When a disc milling cutter is used for batch processing of a plurality of PXE pistons, burrs are easily formed on the excircle of the piston due to the fact that the cutting mode and the cutting angle of the disc milling cutter are different from those of common single processing, the excircle of the piston is affected, and therefore subsequent excircle trimming needs to be carried out.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a can once only cover whole PXE piston excircle axial length to the PXE piston processing milling cutter of type is repaiied fast under high rotational speed.

In order to achieve the purpose, the utility model discloses a PXE piston processing milling cutter, including the handle of a knife, the handle of a knife on be equipped with the tool bit, the circumference of tool bit on the equipartition have three cutting face, the plane at three cutting face place all passes through the centre of a circle of tool bit, just to being equipped with bow-shaped chip groove to cutting the face, and the face of cutting is perpendicular with the plane of chip groove in the tool bit upper end, the epitaxy of cutting the face extend to the circumference of tool bit and form the cutting edge, handle of a knife length be 45mm, the length of tool bit is 35mm, the diameter of tool bit is 9mm, tool bit and handle of a knife pass through the chamfer transition, the radius that contains the cutting edge of tool bit is 5mm, the length of cutting edge.

Compared with the prior art, the utility model discloses a PXE piston processing milling cutter, the length of cutting edge covers the excircle axial length of PXE piston, consequently can one shot forming. Meanwhile, reasonable length and diameter are designed, and the extending plane of the cutting surface directly passes through the axis of the cutter, so that the cutter has good rigidity and toughness at high rotating speed, the processing efficiency is greatly improved, and the service life is greatly prolonged.
