Description

PXE piston machining disc cutter

Technical Field

The utility model relates to a disc cutter of machining, especially a PXE piston processing disc 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.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a PXE piston processing disc cutter that can once only process big batch PXE piston.

In order to achieve the purpose, the utility model discloses a PXE piston processing disc cutter, including the handle of a knife, the handle of a knife on be equipped with the spliced pole, be equipped with the blade disc at the end of spliced pole, the equipartition has the back of a knife blade of loudspeaker form on the circumference of blade disc, the back of a knife blade on be fixed with the dish through welding or glue and mill the blade, the dish mill the blade and use the blade disc to become the radiation to arranging as the centre of a circle, the front of dish milling the blade is the cutting face, the back of dish milling the blade is connected with the back of a knife blade for connecting the face, the edge of cutting face is the cutting edge, the profile of cutting edge extend to outside the radial projection of blade disc, the blade disc just establishes. The cutter is characterized in that a plurality of identical cutters are loaded through the arrangement of the cutter disc, meanwhile, the cutter has good rigidity and toughness, and special abdicating notches are designed for the workpieces, so that the cutters can directly face the whole row of workpieces to perform milling operation.

The further proposal is that 6 cutting surfaces are arranged on the cutter head; the shape of the cutting surface comprises an upper bottom edge, a lower bottom edge and two side edges, wherein the upper bottom edge and the lower bottom edge are straight lines which are parallel to each other, the distance between the upper bottom edge and the lower bottom edge is 6.5mm, the maximum distance between the two side edges is 13.02mm, an angle formed between the upper bottom edge and the lower bottom edge is an obtuse angle 91 degrees, the upper bottom edge and the two side edges are in transition connection through a fillet of R4mm, and the included angle between the cutting surface and the axis of the cutter head is; the maximum diameter that the blade disc contain the cutting edge be 55mm, the diameter of spliced pole is 20 mm. The quality of a PXE piston cavity is accurately controlled by accurately designing the size and the position relation of the cutting surface.

Compared with the prior art, the utility model discloses a PXE piston processing disc cutter on with the circular permutation blade disc of milling cutter, has designed the cutting edge that is higher than general quantity greatly on the blade disc, has still designed the back of a knife blade of loudspeaker form simultaneously, has left the cutting breach of stepping down when the cutter uses, the feed withdrawal position when also reserving the processing blade disc to a special disc milling cutter of PXE piston die cavity that can cut a plurality of transverse arrangement in batches has been produced. On the other hand, the cutting face is specially designed for the PXE piston cavity which is processed in an arrangement mode, particularly the slight angle is formed between the cutting face and the cutter disc shaft, the cutting of the cutting face and the workpiece which is in initial contact can be guaranteed, and therefore the quality and consistency of a plurality of PXE pistons are guaranteed.
