Abstract

The invention belongs to the technical field of manufacturing, repairing and detecting internal combustion engines, and provides a bent axle coaxiality detecting device and detecting technology of a high-power multi-cylinder internal combustion engine. The bent axle coaxiality detecting device of the high-power multi-cylinder internal combustion engine comprises three detecting supports, a dial indicator (13) and a detecting platform (14). Each detecting support comprises a supporting base (1), a supporting body (5) and a lead screw nut mechanism. The detecting support at the main shaft neck part of the free end of a bent axle and the detecting support at the main shaft neck part of the output end of the bent axle are fixed detecting supports. The detecting support at the main shaft neck part in the middle of the bent axle is a movable detecting support, sliding mechanisms are arranged below the supporting bases (1), a measuring contact of the dial indicator (13) is perpendicular to the detecting platform (14), and the coaxiality of each main shaft neck is detected. The building technology implementation and product quality of the bent axle are guaranteed, and technology and quality assurance is provided for reliable operation of the internal combustion engine and the whole device.

Description

technical field [0001] The invention belongs to the technical field of manufacturing, repairing and testing of internal combustion engines, and mainly proposes a crankshaft coaxiality testing device and a testing process of a high-power multi-cylinder internal combustion engine. Background technique [0002] The internal combustion engine is the power plant and the heart of various equipment, and the crankshaft is the key rotating part of the internal combustion engine, so the accuracy of the crankshaft directly determines the performance of the internal combustion engine; a high-power multi-cylinder internal combustion engine consists of several identical single cylinders arranged on one body and share Composed of crankshaft output power, the crankshaft of a high-power multi-cylinder internal combustion engine includes multiple main journals and multiple connecting rod journals. The roundness, cylindricity, straightness of the pin and the main journal, the parallelism betwe...
