Embodiment 1

[0053] Embodiment 1. First refer to figure 1 , the present embodiment provides a kind of engine test stand, engine is installed on this test stand, just can carry out relevant various durability test and function test thereby evaluate the quality performance of engine. Before the test, the operator needs to install the engine on the engine test bench for installation preparation, and after the test, it needs to disassemble. The disassembly here includes the disassembly of the engine.

[0054] The engine test stand 1 in the present embodiment comprises a base (not shown), a first column 2, a second column 3, and a third column 4 that are vertically arranged on the base 9 and are arranged at an angle, and are connected to the first column. The beam 5 between the first column 2 and the second column 3 . The engine test bench 1 also includes a process gearbox 6 and an auxiliary device 7, one side of the process gearbox 6 is connected to the beam 5, and the other side is connected...

Embodiment 2

[0062] Embodiment 2. This embodiment provides a method of using the engine test bench based on Embodiment 1. The specific steps are as follows:

[0063] After the engine performance test is completed, the engine is removed from the engine test bench 1;

[0064] Add an auxiliary device 7 between the process gearbox 6 and the beam 5, so that the process gearbox 6 remains stable;

[0065] When the engine performance test needs to be carried out again, the engine is installed on the engine test bench 1, and the auxiliary device 7 is removed to perform the engine performance test.

[0066] Therefore, during specific operation, before and after the test, only the engine needs to be unloaded separately, and the process gearbox 6 still remains on the engine test bench 1, thereby reducing the steps of disassembling the process gearbox 6 and simplifying the process. Moreover, the disassembly and installation of the process gearbox 6 and the engine can be carried out on the engine test ...

Embodiment 3

[0074] Embodiment 3. First refer to Image 6 , this embodiment provides a general engine test bench, relative to Embodiment 1, the engine test bench in this embodiment is suitable for any type of engine.

[0075] further reference Figure 5 to Figure 9 , the auxiliary device 10 in this embodiment includes a first connecting piece 11, a second connecting piece 12 and an adjusting piece 13, one end of the second connecting piece 12 is vertically connected to the first connecting piece 11, and the other end of the second connecting piece 12 is connected to the beam 5 connections. Compared with Embodiment 1, this embodiment can adjust the longitudinal position of the auxiliary device 12 according to different engine structures by adding the second connecting piece 12.

[0076] Wherein, the first connecting member 11 may be a reduced-diameter stud bolt or a reduced-diameter double-ended screw, and a reduced-diameter double-ended screw is preferred in this embodiment. The first con...

Abstract

The invention discloses an engine experiment stand and an application method thereof. The engine experiment stand comprises a first vertical post, a second vertical post, a third vertical post, a cross beam, a process speed changing box and an auxiliary tool, wherein one side of the process speed changing box is connected with the cross beam, the other side of the process speed changing box is connected with the third vertical post, the auxiliary tool is selectively arranged between the process speed changing box and the cross beam, and the auxiliary tool is connected between the process speedchanging box and the cross beam so that the process speed changing box is maintained firmly when an engine is disassembled from the engine experiment stand. In the engine experiment stand, the process speed changing box is maintained on the engine experiment stand, the engine is only needed to be installed when experiment is needed, the engine is only separately disassembled after the experimentis ended, so that the process step is reduced, time and labor are saved, and engine the experiment stand has relatively high safety and operation convenience; and by additionally arranging the auxiliary tool, the stability of the process speed changing box can be further improved in a non-experiment state after the engine is disassembled, so that the stability of the whole engine experiment standis improved.

Description

technical field [0001] The invention relates to the field of engine testing, in particular to an engine test bench and a method for using the same. Background technique [0002] In the traditional engine test bench installation process, the engine and the process gearbox are first combined on the ground. This process needs to align and match the positioning pins of the two, and coordinate the center hole of the clutch pressure plate at the engine end with the process gearbox. The spline shaft can be fully combined. Due to the coordination work on the ground, the operator cannot see the matching of the positioning pins of the engine and the process gearbox, and the matching state of the center hole of the engine clutch pressure plate and the spline shaft of the process gearbox. I feel that the operation is combined. When combined, the engine and the craft gearbox are very heavy, the volume is too large, and the operation is quite laborious. Moreover, because the combination...
