Example Embodiment

[0013] The manufacturing method of the blind hole compressed air impeller of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0014] See figure 1 , The manufacturing method of the blind hole compressed air impeller of the present invention includes the following steps:

[0015] Step 1: Mount the impeller blank on the CNC vertical lathe, turn the bottom end surface 5, the bottom outer circle 7, the back arc 6 and the large outer circle 1, and machine the blind hole 8 with a reamer. The impeller blank is an integral forging die The turning process is a finishing process, and the reamer can be a high-precision reamer to ensure the machining accuracy. The turning of the bottom end surface 5, the bottom outer circle 7, the back arc 6 and the large outer circle 1 is completed by the same turning tool to ensure the machining accuracy. After the impeller blank is processed in the first step, it can be detected by a three-coo...

Abstract

The invention discloses a manufacturing method of a blind-hole compressor impeller. The manufacturing method comprises the following steps: step 1, installing an impeller blank on a numerical-control vertical lathe, turning the bottom end surface, a bottom end outer circle, a back arc and a large outer circle, and machining a blind hole by utilizing a reamer; step 2, clamping the large outer circle by utilizing three claws, leveling the bottom end surface, and turning a meridian plane and a top end surface; step 3, locating by utilizing the bottom end surface, connecting a bolt with the blind hole by threads, straining the bolt, clamping the back arc and the bottom end outer circle by utilizing a clamp, machining a threaded hole, and milling an inner hexagonal hole, blades and runner. By adopting the manufacturing method, the machining precision can be guaranteed, the production efficiency is improved, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the field of compressor impeller processing of a turbocharger, in particular to a method for manufacturing a blind hole compressor impeller. Background technique [0002] In recent years, due to the development of diesel engines in the direction of high performance, high efficiency and energy saving, higher requirements have been put forward for the compact structure, beautiful appearance, safety and reliability of turbochargers. Compressor impeller is the core part of high-speed rotation in the turbocharger, which provides compressed air with a certain pressure ratio for the diesel engine and improves the efficiency of the diesel engine. [0003] With the continuous improvement of turbocharger technology and the continuous improvement of the compressor impeller structure, so far, the compressor impeller has developed into a form of blind hole integral with long and short blades, and its own dimensional accuracy and shape and p...
