Embodiment Construction

[0024] see figure 1 , 2 as well as image 3 , the processing electrode of the annular hole involved in the present invention includes an electrode head 1, a connecting rod 2 and an electrode rod 3, wherein one end of the connecting rod 2 is connected to the electrode rod 3 by interference or through a screw thread, and the other end is connected to the electrode head through a thread 1 connection. The connecting rod 2 is an arc-shaped rod and a cylindrical rod, that is, the end connecting the connecting rod 2 and the electrode head 1 is set in an arc shape, and the end used for fixing is a columnar structure, and the end of the electrode head 1 is spherical. The end of the connection between the head and the connecting rod is provided with a 0.1-0.2mm wide cylindrical processing ligament, which can reduce the wear of the electrode head 1, ensure the service life of the electrode and the processing quality of the inner surface of the annular hole 4; the material of the electr...

Abstract

The invention provides a machining electrode for annular holes and a machining method. The electrode comprises an electrode rod, a connecting rod and an electrode head, wherein one end of the connecting rod is connected with the electrode rod, the electrode head is arranged at the other end of the connecting rod, and the end of the connecting rod, which is connected with the electrode head is of a circular arc; in the machining electrode for the annular holes and the machining method, the electrode head is made of red copper material, the consumption of red copper is reduced, and the materialcost is reduced; furthermore, rough machining and fine machining share one electrode rod, so the electrode rod can be reused by replacing the electrode head, the operation is simple, and the non-uniform abrasion of the electrode is reduced; furthermore, the machining of a whole part is completed during one-time clamping, so batching of the part or secondary alignment of the electrode is avoided, the alignment time is reduced and the uniformity of the fine machining allowance is ensured.

Description

technical field [0001] The invention belongs to the field of mechanical processing of aviation parts, and in particular relates to a processing electrode and a processing method for an annular hole. Background technique [0002] At present, although the processing difficulty of annular hole is relatively high, it is relatively rare in mechanical design, but because its design can simplify the part structure and realize lightweight design, it still has a certain application range in aviation parts. [0003] Generally, shell parts are made of casting blanks, and the annular holes on them are mostly obtained by pre-embedding mold cores in molds, but the manufacturing cycle of molds is long, which cannot meet the needs of rapid response to the market, and in small batches of single pieces The cost in production is too high. In order to solve these problems, the shape of the blank of the shell part can be obtained by machining, and the processing of the annular hole becomes a dif...
