Abstract

The invention discloses a machining process of a water-cooled motor shell of a new energy automobile. Five-axis one-step machining is completed; after clamping, the pressing plate is tightened, the auxiliary supporting cylinders completely prop against the product to prevent machining deformation during inner circle machining; prevention of improper clamping is realized in gas detection, the clampis prevented from being crushed by an aluminum pin in water detection. Firstly two large surfaces are roughened, two inclined holes in the clamp are machined by rotating an angle, then a central holeand an excircle are roughened, the clamp is loosened and suspended for 5 seconds after he peripheral through hole is machined and then tightened, automatic detecting and compensating are performed bya probe and then the two large surfaces are finely machined and the diameter of the central hole and the excircle is machined so that the mesh surface requirement, the coaxiality and the roundness requirement are ensured.

Description

technical field [0001] The invention relates to a water-cooled motor casing, in particular to a processing technology for a water-cooled motor casing of a new energy vehicle. Background technique [0002] At present, during the processing of water-cooled motor housings for new energy vehicles, the roughness requirements of the two large end faces are high, and the position of the oblique holes on both sides of the avoidance hole is not guaranteed. The diameter of the center hole is too large. The diameter of the circle is 264mm, the coaxiality, cylindricity and parallelism cannot be guaranteed, and the processing is unstable. Contents of the invention [0003] A brief overview of the invention is given below in order to provide a basic understanding of some aspects of the invention. It should be understood that this summary is not an exhaustive overview of the invention. It is not intended to identify key or critical parts of the invention nor to delineate the scope of t...
