Description
Technical field
The present invention relates to the automobile test holder device, relate in particular to a kind of bracket for engine test device.
Background technology
When engine is done bench test, be contained in engine on the testing table support, and the flywheel end of engine is carried out to plane and radial alignment, guarantee that engine locates on support, stable.First unclamp test bracket upper part clamp nut during tradition centering, beat position, support somewhere by iron hammer and adjust engine location, make its flywheel end diameter run-out in 0.3mm, face runout is in 0.2mm.
, when centering, there are following two problems in the conventional engines test bracket: one, constantly with iron hammer, beat test bracket during centering, cause the serious modification of test bracket and damage; Two, adopt during centering the detection termination of dial gauge to be attached to engine flywheel end face and axial plane, beat test bracket by iron hammer and observe the dial gauge reading, and iron hammer while beaing test bracket strength uncontrollable, sometimes firmly cause too greatly gauge outfit place Oscillation Amplitude excessive and damage dial gauge.Thereby the centering method of conventional engines on test bracket both affected test period, also easily damage engine support and dial gauge, the test progress that the hand labor amount is large, affect engine, efficiency is low.
Summary of the invention
In view of this, be necessary to provide a kind of and can not damage dial gauge, can alleviate hand labor amount and the high bracket for engine test device of efficiency.Described technical scheme is as follows:
A kind of bracket for engine test device, comprise fore-stock base, after-poppet base, the first pillar, the second pillar, fore-stock top board, after-poppet top board, front and back automatic adjusting mechanism, front end left and right automatic adjusting mechanism, left and right, rear end automatic adjusting mechanism, the upper and lower automatic adjusting mechanism of front end, the upper and lower automatic adjusting mechanism in rear end, control box and detecting sensor; Described the first shore supports is between described fore-stock base and described fore-stock top board, and described the second shore supports is between described after-poppet base and described after-poppet top board; Described control box is electrically connected with described front and back automatic adjusting mechanism, front end left and right automatic adjusting mechanism, left and right, rear end automatic adjusting mechanism, the upper and lower automatic adjusting mechanism of front end, the upper and lower automatic adjusting mechanism in rear end and detecting sensor respectively; Described detecting sensor, and will detect data transmission and arrive described control box with respect to the end face flatness of dynamometer machine and right alignment radially for detection of engine flywheel; Described control box sends corresponding regulating command to described front and back automatic adjusting mechanism, front end left and right automatic adjusting mechanism, left and right, rear end automatic adjusting mechanism, the upper and lower automatic adjusting mechanism of the upper and lower automatic adjusting mechanism of front end and rear end to detecting after data analysis is processed.
Compared to prior art, the bracket for engine test device that the embodiment of the present invention provides utilizes detecting sensor to detect and obtains data, again by control box control corresponding automatic adjusting mechanism to engine flywheel end face flatness and radially right alignment automatically adjust, compare and there are following three place's advantages with the conventional engines test bracket: when one, centering, no longer with iron hammer, beat test bracket, alleviate the hand labor amount, and avoid the serious modification of test bracket and damage; Two, centering only needs detecting sensor to be attached to engine flywheel end face and axial plane, by the bracket for engine test device, can exactly, adjust flatness quickly and easily, after the flatness adjustment completes, again through the bracket for engine test device, can exactly, adjust right alignment quickly and easily, the purpose concentric with the crankshaft center line of engine with the connection axis that reaches dynamometer machine, adjusting efficiency is high; When three, the bracket for engine test device carries out centering, during centering, do not adopt dial gauge to be detected data, but adopt detecting sensor to complete DATA REASONING, so do not exist dial gauge to damage phenomenon.
