Centering debug method of multiple racks and trays of engine test stand

Abstract

The invention discloses a centering debug method of multiple racks and trays of an engine test stand. The method comprises the following steps: optionally selecting a set of reference rack P and a set of reference tray Q, installing an engine on an engine support of the reference tray Q; adjusting the reference tray Q and the reference rack P, so as to ensure that the rack main shaft of the reference rack P and the main shaft of the engine on the reference tray Q meet the centering requirement; selecting a test stand W to be conducted to centering adjustment, and installing the reference tray Q on the test stand W; adjusting the rack of the test stand W and a guide positioning device on the base of the test stand W, so as to realize the guiding of the reference tray Q when the reference tray Q enters the test stand and the positioning of the rack, and adjusting a fastening device used for fastening the rack onto the test stand W, so as to ensure that the rack main shaft of the test stand W and the main shaft of the engine on the reference tray Q meet the centering requirement; selecting a tray N to be conducted to centering adjustment, and installing the tray N on the reference rack P; and adjusting the engine support, so as to ensure that the main shaft of the engine on the tray N and the rack main shaft of the reference rack P meet the centering requirement.

Description

technical field [0001] The invention relates to the debugging of an automatic engine test bench, in particular to the exchange and alignment debugging of a bench and a pallet. Background technique [0002] The factory inspection of the engine is a link that must be completed before each engine leaves the factory to check whether the engine has any abnormality and whether it has reached the theoretical performance of the engine. Therefore, the factory test bench of the engine has become a necessary test equipment for manufacturers. At present, there are many types of such equipment. And can realize automatic engine transportation, docking and testing. [0003] For example, Chinese Patent No. 01223188.6 discloses an integral bench for automatic engine testing, including a test system with a main shaft, a bench for installing the test system, a base for installing the bench, and extending along the front and rear docking directions A male guide rail provided on the base, and a...

AI Technical Summary

Problems solved by technology

The adjustment items include the male guide rail and the female guide rail, the positioning pin shaft and the positioning pin sleeve, and the engine bracket. The adjustment process is cumbersome, the accuracy adjustment is difficult, and the workload is large.

Therefore, it is necessary to strictly manage the matching racks and pallets during production to avoid confusion, and once there is confusion, it may be necessary to re-test each set of equipment, wasting a lot of time

In addition, if a pallet or rack fails during use, since the faultless rack or pallet cannot be adapted to other pallets or racks that are not matched, the entire set of equipment will be unusable, which will affect the utilization rate of the equipment. It has a great impact and restricts the efficiency of automated testing
