An integrated shock absorption test tool for a turbocharger dynamic balance test machine

Abstract

The invention discloses an integrated damping test tool for a turbocharger dynamic balancing tester. The integrated damping test tool for the turbocharger dynamic balancing tester comprises a clampingplate and a ring block; the outer side of the front of the clamping plate is equidistantly provided with a first screw hole in a surrounding mode; the inner side of the front of the clamping plate isequidistantly provided with a second screw hole in a surrounding mode; and the inner side of the clamping plate is equidistantly provided with four groups of link strips. The accuracy of the dynamicbalance test of the turbocharger is improved; the force between the clamping plate and an inner ring is more balanced and the stability is stronger; the inner ring, the link strip and the clamping plate are formed one casting; the assembly of a third screw hole, a second screw hole and an installation screw hole is used to facilitate the assembly of a guide gaseous disk and an inner ring, a spacerof silica gel material is used, the vibration cushion effect of the turbocharger is also achieved; and, meanwhile, the spacer is installed through the first screw in the second screw hole, thus facilitating the replacement of the spacer.

Description

technical field [0001] The invention relates to the technical field of a turbocharger dynamic balance testing machine, in particular to an integrated shock-absorbing test tool for a turbocharger dynamic balancing testing machine. Background technique [0002] A turbocharger is actually an air compressor that compresses air to increase intake air. It uses the inertial momentum of the exhaust gas discharged from the engine to drive the turbine in the turbine chamber, and the turbine drives the coaxial impeller, which presses the air sent by the air filter pipe to pressurize it into the cylinder. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, and the impeller compresses more air into the cylinder. The pressure and density of the air increase to burn more fuel. Increase the amount of fuel and adjust the engine speed accordingly. The output power of the engine can be increased. [0003] After the machining of ...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an integrated shock absorption test tooling for a turbocharger dynamic balance testing machine, which solves the need to use a dynamic balancing testing machine to perform dynamic testing on the turbocharger after the machining is completed. Balance test, during the dynamic balance test, with the rotation of the turbocharger, the test tool of the dynamic balance test machine will vibrate, which will affect the test results. However, the current tool of the turbocharger test machine is a solid structure. It not only has more consumables, but also does not have the problem of shock absorption effect or poor shock absorption effect
