Embodiment Construction
[0027] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in a variety of different ways defined and covered by the claims.
[0028] Reference figure 1 The preferred embodiment of the present invention provides a method for machining the outer conical surface of a shaft workpiece. The finished shaped workpiece 10 is a shaft, and the outer circular surface has a first conical surface 101 extending in the axial direction. The surface 101 is arranged in multiple sections along the axial direction, and each first conical surface 101 is an outer circular surface of a tapered section, and the outer circular surface of the forming workpiece 10 also has a reference surface 102 arranged opposite to the large end of the first conical surface 101 , There is a set distance between the large end of the first conical surface 101 and the reference surface 102, and the processing meth...

The invention discloses a method for processing the outer conical surface of a shaft workpiece. The method comprises a step of corresponding adjusting the processing taper of processing equipment according to the taper of a first conical surface, a step of performing trial processing on a workpiece blank piece by using the processing equipment to form an adjustment workpiece with a conical section, a step of coloring an outer circular surface on an outer round surface of the conical section to judge whether the taper of the outer conical surface of the adjustment workpiece is equal to the taper of a first conical surface or not, and adjusting the processing taper again until the taper of the outer conical surface of the processed adjustment workpiece is equal to the taper of the first conical surface if not, and a step of formally processing the workpiece blank piece by using the adjusted processing equipment to form a processed workpiece, detecting whether a detection distance betweena large end of an outer circular surface of the processed workpiece and a reference surface on the processed workpiece is in a set distance range or not, continuing to process the outer circular surface of the processed workpiece until the detection distance is in the set distance range if the detection distance is larger than a set distance, and processing the processed workpiece to form a formed workpiece.
Description
Technical field [0001] The invention relates to the field of shaft-like parts processing, in particular to a method for processing the outer conical surface of a shaft-like workpiece. Background technique [0002] There are many kinds of shaft workpieces on aero engines, one of which is precision bolt shafts. The length of the workpiece is generally between 100-300mm and the diameter is between Φ8mm-Φ20mm. The workpiece has an outer conical surface. In the process, the taper surface is matched with the bolt hole, and there is a stricter diameter size requirement for the outer circle of the taper surface at a specific length position in the axial direction, which brings greater difficulty to the processing and low processing efficiency and processing pass rate. Such as figure 1 Shown is one of the workpieces. There are two tapered outer circles 101, the taper is 1:48, and the outer diameter at the axial position 1.5±0.12mm away from the end surface is required to be Φ15.77(+0.04, ...
