Detailed Description

The invention is described in further detail below with reference to the accompanying examples.

As shown in fig. 1 and 2, the deburring blade device in the present embodiment includes a base 1, a first tool rest 6, and a second tool rest 7, wherein a first shaft seat 11 and a second shaft seat 12 are respectively formed on two sides of the base 1; the middle part of the first knife rest 6 is rotatably arranged on the first shaft seat 11 through a first rotating shaft 21; the front end of the first knife rest 6 is detachably provided with a first scraper 31, and the rear end is elastically connected with the base 1; the first knife rest 6 is arranged in a lever type.

The middle part of the second tool rest 7 is rotatably arranged on the second shaft base 12 through a second rotating shaft 22; the front end of the second knife rest 7 is detachably provided with a second scraper 32, and the rear end is elastically connected with the base 1; the second blade 32 is disposed to intersect the first blade 31. The second tool holder 7 is arranged in a lever-type manner.

The first scrapers 31 in this embodiment are two and arranged side by side at intervals, and the second scrapers 32 are inserted in the gaps between the first scrapers 31.

A first connecting post 41 is arranged on one side of the first shaft seat 11, a first spring 51 is sleeved on the first connecting post 41, the rear end of the first knife rest 6 is sleeved on the first connecting post 41 and can move back and forth along the first connecting post 41, and the rear end of the first knife rest 6 is abutted against the first spring 51.
