Abstract

This utility model relates to a kind of part and becomes the anti-scraper of hole machined, the cutter head of this cutter is connected on tool rest by eccentric rod, and eccentric rod includes inside eccentric rod and outside eccentric rod, inside eccentric rod and integral outside eccentric rod, it is oval contour body inside eccentric rod, is cube outside eccentric rod.Use this utility model, owing to being oval contour body inside eccentric rod, under coordinating with all-in-one-piece outside eccentric rod, neither affect the processing diameter range that even can increase pore-forming, its rigidity being connected with tool rest and toughness can be improved again, prevent from fractureing.

Description

A kind of part becomes the anti-scraper of hole machined

Technical field

This utility model relates to a kind of part and becomes the anti-scraper of hole machined.

Background technology

At present, when the reverse side of the through hole of a part has a pore-forming, effect due to interference surface, common cutter cannot be introduced into processing, in order to solve this problem, it usually needs anti-scraper tool sharpening, and this anti-scraper cutter all has eccentric structure, it is usually and is made up of cutter head, the eccentric rod of strip and block and tool rest, and this cutter the most often occurs eccentric rod breakage phenomenon, causes processing part impaired.

Summary of the invention

The purpose of this utility model is to provide a kind of part that can prevent eccentric rod from fractureing and becomes the anti-scraper of hole machined.

This utility model adopts the technical scheme that: a kind of part becomes the anti-scraper of hole machined, including cutter head, eccentric rod and tool rest, cutter head is connected on tool rest by eccentric rod, it is characterized in that eccentric rod includes inside eccentric rod and outside eccentric rod, inside eccentric rod and eccentric rod outside integral, it is oval contour body inside eccentric rod, is cube outside eccentric rod.

Use this utility model, owing to being oval contour body inside eccentric rod, under coordinating with all-in-one-piece outside eccentric rod, neither affect the processing diameter range that even can increase pore-forming, its rigidity being connected with tool rest and toughness can be improved again, prevent from fractureing.

Accompanying drawing explanation

Fig. 1 is schematic perspective view of the present utility model.

Fig. 2 is schematic side view of the present utility model.

In figure, sequence number represents: inside tool rest 1, eccentric rod 2, cutter head 3, eccentric rod 4 and eccentric rod outside 5.

Detailed description of the invention

Below in conjunction with specific embodiment, utility model is described further.

See figures.1.and.2, this part becomes the anti-scraper of hole machined to include cutter head 3, eccentric rod 2 and tool rest 1, cutter head 3 is connected on tool rest 1 by eccentric rod 2, eccentric rod 2 include inside eccentric rod 4 and eccentric rod outside 5, inside eccentric rod 4 and eccentric rod outside 5 integral, inside eccentric rod, 4 is oval contour body, and outside eccentric rod, 5 is cube.Owing to inside eccentric rod, 4 is oval contour body, with under 5 all-in-one-pieces coordinate outside eccentric rod, neither affect the processing diameter range that even can increase pore-forming, its rigidity being connected with tool rest and toughness can be improved again, prevent from fractureing.

Claims (1)

1. a part becomes the anti-scraper of hole machined, including cutter head, eccentric rod and tool rest, it is characterised in that eccentric rod includes inside eccentric rod and outside eccentric rod, inside eccentric rod and integral outside eccentric rod, it is oval contour body inside eccentric rod, is cube outside eccentric rod.
