Abstract

The invention discloses a back spot facing machining cutter and an application method thereof. The cutter comprises a cutter bar, a cutter head and a bolt, wherein a cutter head mounting hole is formed on the front part of the cutter bar, and the cutter head is fixed in the cutter head mounting hole; a threaded through hole is formed at the front end of the cutter bar, and the bolt is arranged in the through hole; and the bolt is fixedly connected with the cutter head. The back spot facing machining cutter has the advantages that: the problems of manual cutter assembly and disassembly, shut down and low machining efficiency during the traditional machining process of back spot facing can be solved by designing the special back spot facing machining cutter which has a smart manufacturing structure and is simple and practical, and automatic machining process of the back spot facing is realized; a special cutter is provided for the equipment with high machining automation degree, such as horizontal machining equipment, vertical machining equipment and the like, a mechanical arm can automatically change a cutter, and the machining efficiency can be greatly improved.

Description

Technical field: [0001] The invention belongs to the field of tool processing, and relates to a countersink machining tool and an application method thereof, in particular to a special machining tool for countersinking on high-voltage switchgear parts and an application method thereof. Background technique: [0002] In the prior art, when processing the back spot facing, the tool is fed from the end face of the large hole, and the small hole is processed first, and then the large hole is processed. However, due to the limitation of the structure of some parts, the tool is fed from the end face of the large hole, and the tool and the part will interfere, so the tool can only be fed from the end face of the small hole. Bottom of the large hole to the direction of the small hole) to process the large hole. This kind of large hole is called "back countersinking", this processing method is called "backsinking processing", and the tool used is called "backsinking knife". figure ...
