Indexable deburring cutter for inner wall cross orifice

Abstract

The invention discloses an indexable deburring cutter for an inner wall cross orifice. The indexable deburring cutter comprises a cutter bar, an ejector rod and a blade; an open groove is formed in the left end of the cutter bar, and the blade is rotatably mounted on the open groove through a rotating shaft; and the ejector rod is arranged in an inner hole of the cutter bar, and the ejector rod can move leftwards to push the blade to rotate and move rightwards to enable the blade to reset. By the adoption of the indexable deburring cutter, the mode of stretching in from a cavity opening for deburring is changed into the mode of stretching in from the orifice of the outer wall, the deburring mode is changed into the mode of rotating a cutter handle, the needed inner cavity space is greatly reduced, and the limitation of the inner cavity size and the inner cavity structure is avoided. The deburring cutter enables the cutting edge to fall on the inner wall orifice like a drill bit front chamfer, and burrs are clearer compared with a traditional method.

Description

technical field [0001] The invention relates to the technical field of machining tools, in particular to an indexable deburring tool used for intersecting holes on inner walls. Background technique [0002] In the processing of aerospace parts, the structure of small holes on the wall often appears. When processing such holes, a certain amount of waste will remain on the inner wall and adhere to the opening of the inner wall. For aerospace products, if such swarf remains, it is very easy to fall off when the supporting finished product is used, affecting the performance of the product. [0003] To clean this type of inner wall hole burr, the traditional method is to use the head of a small triangular file to scrape the inner wall hole and remove the burr from the hole. However, this method is only applicable to the case where the circular or rectangular inner cavity corresponding to the opening on the inner wall is relatively large. If the inner cavity of the part is too s...

However, this method is only applicable to the case where the circular or rectangular inner cavity corresponding to the opening on the inner wall is relatively large. If the inner cavity of the part is too small, or the through cavity is not easy to insert, the small triangular file cannot be adjusted. To scrape the orifice at a favorable angle, the side close to the cavity is often cleaned, and the hard edge on the other side cannot be processed
