Description

Technical Field

[0002] A part that holds shaft parts by its own deformation, such as a guide shaft support, is a T-shaped notch processed on a circular part, that is, a vertical groove is first processed on the surface of the circular part, and then a horizontal groove connected to the vertical groove is cut horizontally, and the horizontal groove of the T-shaped notch is deformed by the cooperation of bolts and nuts, thereby holding the shaft parts.

[0003] The processing of T-shaped notches is generally done by cutting with a milling cutter on a milling machine, that is, the circular part is clamped vertically on the milling machine, the milling cutter first cuts vertically to produce a vertical groove, and then the circular part is fixed horizontally to produce a horizontal groove. However, since the milling cutter is circular, for circular parts with thicker walls, the horizontal groove may not be cut thoroughly, and there will be an arc-shaped groove near the inner hole of the circular part, which requires further processing in the later stage, which is more cumbersome.

[0004] In addition, the transverse groove only needs to be set on one side of the inner hole of the annular part, and the existing wire cutting method will cut the transverse grooves at both ends of the inner hole, which cannot meet the processing requirements. Therefore, the existing wire cutting method cannot be implemented.

[0005] In view of this, it is urgent to design a semi-transverse groove processing device and processing method for circular ring parts to solve the problems in the prior art that the milling cutter cutting method requires secondary processing and the wire cutting cannot meet the processing requirements.
