Abstract

The invention discloses a forming device of an inner taper hole of a side wall. The forming device comprises a cutter and a cutter bar, wherein the cutter has a tapered structure; the surface of the cutter is provided with cutter teeth; the cutter is connected with the cutter bar in a pin mode; one end of the cutter bar is provided with a pin; and the middle part of the cutter is provided with a pin through hole. Compared with the prior art, the forming device of the inner taper hole of the side wall has the advantages that the cutter and the cutter bar are locked in a pin rotating mode to quicken and facilitate assembly and disassembly; the technical problem of incapability of machining of a main hole and an inner taper hole of the side wall by using the conventional drilling device is solved; the machining efficiency of the inner taper hole is greatly increased; and the machining cost can be saved.

Description

technical field [0001] The invention relates to the field of drilling tools, in particular to a forming device for a tapered hole in a side wall. Background technique [0002] The parts of some products are outside the main hole, and taper holes need to be drilled on the inner wall of the main hole. Due to the special position of the taper hole, the processing is extremely difficult, and there is no better processing method for reference. At present, the existing general processing method is to use electroporation technology, which not only takes a long time to process, but also because the electrode material is copper, the internal structure is relatively loose, and the tapered surface of the electrode is easy to Forming a honeycomb shape, sometimes the conical surface pierced out does not meet the design requirements of the product, consumes a lot of power, and consumes a large amount of copper electrode material, resulting in high processing costs. Contents of the inve...
