Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] Such as figure 1 (a) to image 3 (b) The method for optimizing the chamfer shape of mechanical processing, using numerical control programming means to optimize the smooth transition of the chamfer of the outer diameter C2 of the shaft part or the sharp edge of the C1 chamfer of the inner hole of the disc part, including The steps are as follows: A. Carry out CNC programming in advance according to the design requirements; B. Use a CNC lathe to process the parts that need chamfering to the outer diameter C2 chamfering of shaft parts or the inner hole C1 chamfering of disc parts; C. 1. Round the two sharp edges of each chamfer processed above, and process two arcs with R0.5~1.

[0022] When CNC lathes are used to process shaft or disk parts, one-time forming can be achieved, that is, chamfers and sharp edge rounding can be processed by CNC programming in one too...

Abstract

The invention discloses a method for optimizing the shape of a machined chamfer. The sharp edges of an outer diameter chamfer C2 of a shaft part or an inner bore chamfer C1 of a disc part are subjected to smooth transition optimization processing in a machining mode to obtain two circular arcs with radii ranging from 0.5 to 1. The method for optimizing the shape of the machined chamfer is a machining method for improving assembly quality when shaft parts, disc parts and other parts are subjected to numerical control turning. At the time of programming of numerical control machining, appropriate techniques are adopted to optimize the chamfer shape by machining the two sharp edges of the chamfer into the circular arcs with certain sizes R, it is avoided that the parts scratch a corresponding piece due to the sharp edges, and the purposes that design requirements are met and product assembly quality is improved are achieved; after optimization, the appearance and assembly quality of the parts of this kind can be improved remarkably, and therefore performance indexes of assembled products can be effectively increased.

Description

technical field [0001] The invention relates to the technical field of numerical control machining, in particular to a method for optimizing the chamfer shape of machining. Background technique [0002] At present, shafts and disks such as motor shafts, end covers, bearing seats, etc. are processed by CNC lathes. When designing shaft and disk parts, the design drawing generally only requires chamfering at the shaft shoulder and hole, such as C1, C2, etc. When machining the chamfering of such parts by CNC, only complete 45° chamfering is processed according to the design requirements . In this way, the chamfered sharp edge will still be like a knife edge in the subsequent motor assembly process, especially in some interference assembly, which may scratch the corresponding assembly. [0003] In the prior art, the invention patent application with the application number 201080012079.X discloses a wafer chamfering processing method. The present invention provides a wafer chamf...
