Embodiment Construction

[0024] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0025] Such as Figure 1-Figure 5 As shown, in this embodiment, a machining process for a thin-walled cast aluminum volute includes the following steps:

[0026] 1) Select the rough machining benchmark, select the upper end surface 4 of the volute and the inner hole 2 as the rough machining benchmark.

[0027] 2) Machining datum plane and threaded holes, on the vertical machining center, the rough machining datum positioning milling bottom surface 5 is used as the datum plane, and 8 M6 threaded holes are drilled on the bottom surface 5.

[0028] 3) To install the base tooling 6, first fix the base tooling 6 on the workbench of the vertical machining center, the base tooling 6 is a thick-walled tubular structure, the diameter of its inner hole is slightly larger than the diameter of the inner hole o...

Abstract

The invention discloses a machining process for a thin-wall aluminum volute. The machining process comprises the following steps: 1) selecting a rough machining reference; 2) machining a reference surface and a thread hole; 3) installing a base fixture; 4) roughly machining a hole, an end surface and the thread hole; 5) carrying out heat treatment; 6) finely milling the end surface; and 7) finelyboring an inner hole. The machining process disclosed by the invention is definite in reference, convenient to clamp, and high in machining efficiency and dimensional stability, only needs vertical machining centre equipment, and is especially applicable to machining for the thin-wall aluminum volute.

Description

technical field [0001] The invention relates to a machining process for a thin-walled aluminum volute, which is suitable for machining the shell of a centrifugal fan. Background technique [0002] The volute is one of the main parts of the centrifugal fan (see attached figure 1 ). Its main function is to collect the gas from the impeller, guide it to the outlet of the volute, transport the gas to the pipeline or the atmosphere, and convert part of the kinetic energy of the gas into pressure energy. [0003] Existing thin-wall cast aluminum volutes are mostly processed by vertical lathes, radial drilling machines, vertical milling machines, etc. The sequence of workpiece circulation is many, and it needs to be clamped and aligned multiple times. In addition, the shape and structure of the volute are irregular, and it is a thin-walled aluminum casting, which makes clamping difficult and easy to deform. Contents of the invention [0004] The technical problem to be solve...
