The invention discloses a volute positioning tool. The volute positioning tool comprises a base and a three-jaw chuck driven by a main oil cylinder. A cylinder block of the main oil cylinder comprisesa first main oil cavity and a second main oil cavity which are spaced. The three-jaw chuck is arranged on the base. Jaws of the three-jaw chuck are provided with tongue pieces extending into a throatpart of an inner pore of a middle shell end; The volute positioning tool further comprises lifting assemblies used for jacking up a volute. Each lifting assembly comprises a support, a ram and a lifting cylinder, wherein the support is fixed to the base; one end of the ram is hinged to the support, and the other end of the ram is located on the lower portion of the volute; a piston rod of the lifting cylinder extends upwards and is located below the middle position of the ram. The first main oil cavity is connected with a high-pressure oil channel and a low-pressure oil channel. The second main oil cavity is connected with a return oil pipe. The volute positioning tool easily, practicably and effectively achieves positioning of the volute and is high in positioning precision, and the volute machining quality is effectively improved.
Description
Technical field [0001] The invention relates to the field of turbochargers, in particular to a scroll casing positioning tool and a positioning method thereof. Background technique [0002] At present, many cars use turbocharger structure engines. Turbochargers are actually a kind of air compression. It uses the inertial force of exhaust gas discharged from the engine to push the turbine, and the turbine drives the coaxial impeller. Send the air from the air filter pipe to pressurize it into the cylinder. [0003] The volute is one of the important parts of a turbocharger, such as figure 1 Shown is the structural diagram of the volute. At present, this type of volute uses a common three-jaw chuck for clamping and positioning during the processing and production process, which has the problem of poor positioning accuracy, which greatly affects the quality of product processing. , Urgently needs to be solved. Summary of the invention [0004] The purpose of the present invention is ...
