Abstract

A measuring device for the mounting dimensions of a core rotor of a turbocharger relates to the measuring device for the mounting dimensions of the turbocharger, which aims at the problems that the existing measuring method for the mounting dimensions of the core rotor of the turbocharger has fussy technique, high intensity of worker labor, and low measuring precision, and can not be applicable to the automatically assembling work. A left support frame and a right support frame are fixedly connected with a left V-shaped locating block and a right V-shaped locating block. The centering assembly of a right rotor is fixedly connected with the right support flame. A left cylinder and a right cylinder are both fixedly connected with a base. A positioning head is fixedly arranged on the right cylinder. The left cylinder is connected with a connecting bar, an X direction of which is fixedly connected with a Y directional left accurate electric control terrace part. A left displacement pickup and a right displacement pickup are arranged on a left mounting rack and a light mounting rack. An impeller measuring head is connected with a left third mounting plate, the Y direction of which is fixedly connected with an X directional right accurate electric control terrace part. A turbine measuring head and a shifting fork are fixedly connected with a right first mounting rack. A motor is connected with the shifting fork by a synchronous toothed belt mechanism. The measuring device has the advantages of simple operation, high measuring accuracy (can reach 5 micron), and is suitable for automation assembling work.

Description

technical field [0001] The invention relates to a turbocharger assembly dimension measuring device. Background technique [0002] At present, the method commonly used in the industry to measure the assembly size of the turbocharger core rotor is: before assembling the casing, place a circle of lead wire at the position where the diameter of the impeller (turbine) is measured, assemble the pressure casing (volute), tighten the screws, and then disassemble the pressure casing. Shell (volute), take out the lead wire, measure the thickness of the lead wire with a caliper, and use this value as the assembly clearance. This method has the problems of cumbersome process, high labor intensity of workers, low measurement accuracy and inapplicability to automatic assembly operations. Contents of the invention [0003] The purpose of the present invention is to provide a turbocharger core rotor assembly size measurement device to solve the existing turbocharger core rotor assembly s...
