Embodiment

[0027] see Figure 1-Figure 4 , an engine test bench device, including an iron base plate 9, two bench limit blocks 11, four rubber guide wheels 10, a front pad 4, a rear pad 8, a trolley tray body 2 and a trolley pressing mechanism 3 .

[0028] The iron base plate 9 is a rectangular thick steel plate, and its steel plate surface is longitudinally provided with more than four iron base plate T-shaped grooves 91 at equal intervals. The two stand limit blocks 11 are respectively located in the front row of the iron base plate 9 and are fixedly connected to the iron base plate 9 . Two pieces of rubber guide wheels 10 are respectively provided on the top surface of the T-shaped groove 91 of the iron base plate 9 left and right sides, and are fixed on the iron base plate 9 by T-shaped bolts. Its function of stand limit block 11 and rubber guide wheel 10 is to realize the positioning effect of dolly pallet body 2 on iron base plate 9 faces.

[0029] The trolley tray body 2 and th...

Abstract

The invention relates to an engine test rack device, which comprises an iron bottom plate, a rack stop block, a rubber guide wheel, a trolley tray body, a trolley hold-down mechanism, a centering mechanism and supporting legs and the like. A trolley tray can freely move under the pushing of people. A trolley locating guide mechanism and the trolley hold-down mechanism are fixedly installed on the iron bottom plate in an engine test room, and the supporting legs are arranged on the trolley tray. An engine to be tested can be fixed and centered on the engine test rack device in advance and enters into the test room, and then a rack is set up. Compared with traditional methods for setting up racks, by means of the engine test rack device, not only the work efficiency is greatly increased, but also the centering accuracy of parts to be tested can be remarkably improved.

Description

technical field [0001] The invention relates to a test device, in particular to an engine test bench device. Background technique [0002] Under normal circumstances, after an engine is finalized in design and trial-manufactured, various types of performance tests must be carried out in the test bench (engine test room) to verify whether the various indicators of the engine (such as fuel consumption, etc.) Only after meeting the design requirements and passing the test and verification, the engine can be approved for mass production and put on the market. In order to carry out the engine test work in an orderly manner, the engine under test must be built on a bench before the test. The content of the bench construction is: first, fix the engine under test at a designated position in the laboratory, The tested engine is connected with the test equipment (dynamometer); then some temperature, pressure and torque sensors are arranged on the tested engine; finally, the tested en...
