Novel centring device for engine simulation experiment

Abstract

The invention discloses a novel centring device for engine simulation experiment, which belongs to the field of detection fixtures for automobile parts. The novel centring device comprises a circular fixing plate, a steel tube, a detection needle and a slide sleeve, wherein a thread guide sleeve is fixed at the middle of the circular fixing plate, an external thread is engraved at the left end of the steel tube, a detection needle fixing rod is fixed at the right end of the steel tube along a radial direction, and the detection needle fixing rod is of a cuboid structure; the slide sleeve is of a rectangular-ambulatory-plane structure and in slide fit connection with the detection needle fixing rod; the detection needle is of a Z-shaped structure, and the tail portion of the detection needle is vertically and fixedly connected with the slide sleeve; the external thread at the left end of the steel tube is matched with the internal thread of the thread guide sleeve. The detection radius of the novel centring device disclosed by the invention is capable of being continuously adjusted according to the side of the flywheel of the detected engine; the novel centring device is reasonable in structural design, low in production cost and good in adaptability; experiment preparation time is reduced, and detection efficiency is increased.

Description

technical field [0001] The invention belongs to the field of detection tooling for auto parts, and more specifically relates to a centering device for a novel engine simulation experiment. Background technique [0002] With the development of the automobile industry, the research and development of new engine models and new technologies have also received extensive attention and attention. In order to verify new models or new technologies, most engine manufacturers have introduced dynamometers and supporting control devices to perform various simulation operations on the engine test bench and test the output power of the engine. When the engine and the dynamometer are manually connected, the coaxiality of the two connection points is not easy to accurately judge, and it is easy to have deviations, which will cause the body to vibrate violently and cause damage to the equipment. The traditional detection method scans the outer circular surface of the engine flywheel through ...

When the engine and the dynamometer are manually connected, the coaxiality of the two connection points is not easy to accurately judge, and it is easy to have deviations, which will cause the body to vibrate violently and cause damage to the equipment

The traditional detection method scans the outer circular surface of the engine flywheel through a fixed-length bracket and a pointer. It is necessary to determine the size of the engine flywheel in advance, and then select a detection pointer with a fixed radius according to the needs. It is impossible to flexibly detect the pointer itself according to actual needs. adjustment
