Adjustable tool clamp for compressor impeller five-axis machining

Abstract

The invention discloses an adjustable tool clamp for compressor impeller five-axis machining. The adjustable tool clamp comprises a round chassis, and four guide grooves are evenly distributed in the round chassis and arranged in a crossed shape. An adjustable locating block capable of moving in the length direction of the guide grooves is arranged in each guide groove, and the top ends of the four adjustable locating blocks jointly form a supporting face used for supporting the back of a compressor impeller to be machined. A central hole is formed in the center of the round chassis, a central locating rod used for being connected with the compressor impeller to be machined in a sleeved mode is arranged in the central hole, and the upper portion of the central locating rod is provided with a compressor impeller locking structure. Through the method, the adjustable tool clamp is simple and reasonable in structure, the size of an opening can be adjusted according to the actual size of the compressor impeller to be machined, frequent replacement of clamps is not needed, machining efficiency is improved, and excellent generality and practicality can be achieved.

Description

technical field [0001] The invention relates to the technical field of tooling fixtures, in particular to an adjustable tooling fixture for five-axis machining of an impeller. Background technique [0002] The working principle of the turbocharger is to drive the turbine to rotate at a high speed through the engine exhaust gas, absorb the energy of the engine exhaust, and at the same time drive the coaxial compressor blade impeller to compress fresh air into the engine cylinder to achieve the purpose of supercharging. The pressure impeller not only needs the best performance of compressed air, but also bears the centrifugal force brought by the high speed, as well as stable reliability and long service life. [0003] The pressure impeller of aluminum alloy material processed by five-axis machine tool has the following advantages: the material is light in weight, the work of air compression is large; the energy head given is large; the flow loss of gas flowing through the pre...

Problems solved by technology

[0004] However, the five-axis machining process of the impeller is very complicated, and the requirements for the fixture are very high. In the traditional fixture, most of the fixed supporting fixtures are used, that is, a set of fixture for the impeller; Press the impeller, it is necessary to re-adjust the machine tool and processing parameters, and re-customize the tooling; the effective processing time and processing efficiency are greatly reduced
