[0024] Please refer to Figures 1-4 In the embodiment, the sliding installation assembly comprises threaded seats 201, an installation platform 202, bolts 203 and a support plate 204. The inner left sides of the two sliding grooves 18 are slidably connected with the threaded seats 201. The upper end left side of the base 1 is provided with the installation platform 202. The upper end of the installation platform 202 is internally provided with a group of bolts 203 on the front and rear sides. The two groups of bolts 203 are connected with the corresponding threaded seats 201. The upper end middle position of the installation platform 202 is provided with the support plate 204. The left end of the fixed flange 3 is connected with the right end of the support plate 204. The threaded seats 201 are adjusted to the appropriate positions in the sliding grooves 18, and then the installation platform 202 is positionally fixed by using the bolts 203. The support plate 204 is provided for installing the fixed flange 3, so that the installation position can be adjusted according to the needs. The inner right sides of the two sliding grooves 18 are slidably connected with the sliding blocks 8. The upper ends of the two sliding blocks 8 are provided with the connecting plates 9. The sliding blocks 8 are provided. When the sliding blocks 8 are moved, the connecting plates 9 are moved. When the connecting plates 9 are moved, the engine is moved by the connected parts. The upper end middle position of the connecting plate 9 is internally and threadedly connected with the screw rod 10. The outer surface middle position of the screw rod 10 is threadedly connected with the nut 11. The upper end of the screw rod 10 is provided with the tray 12. The screw rod 10 is provided. Since the screw rod 10 and the connecting plate 9 are threadedly connected, when the screw rod 10 is rotated, the screw rod 10 can be moved. When the screw rod 10 is moved, the tray 12 is moved.

[0026] In the working process, the engine cold test installation clamp is fixed in position by using the mounting plate 16 and the bolt, and then the position of the movable threaded seat 201 is adjusted to confirm the appropriate installation position. After confirmation, the engine to be cold tested is moved to the side of the fixed flange 3 using a suitable lifting tool, and the center of the engine crankshaft is roughly aligned with the center of the fixed flange 3. Then, according to the distance between the threaded holes on the engine cylinder body, select the appropriate connecting bracket 6, and use the bolt three 7 to roughly fix the connecting bracket 6 to the engine, and then tighten the bolt two 5 appropriately. By moving the sliding block 8 to adjust the left and right positions of the tray 12, and adjusting the up and down positions of the tray 12 by cooperating with the screw rod 10, the tray 12 can support the engine. When the engine is placed, the shock pad 15 reduces the impact force when the engine is placed. After the placement is completed, the bolt two 5 and the screw rod 10 are completely tightened, and then the lifting tool is removed. Finally, check the engine placement state, if there is no problem, then tighten the nut 11, otherwise, adjust the nut 11 after tightening, and then remove the engine, just loosen the bolt two 5 and the bolt three 7.
[0027] Through the above steps, by setting the bolt two 5, for installing different length of connecting bracket 6, meet the installation needs of various engines, using the U-shaped groove 4 characteristics of the fixed flange 3, ensure that the connecting bracket 6 has axial sliding adjustment and full circumferential rotation freedom, when the connecting bracket 6 moves to the predetermined coordinate in the U-shaped groove 4, fasten the bolt two 5 to realize rigid fixation, then through the bolt three 7, the connecting bracket 6 and the engine body are finally fastened, so as to achieve the purpose of fixing different size engines, to solve the problem that the existing engine cold test installation fixture lacks the function of adapting to different engines, because there is no function of adapting to different engines, the design of this fixing method has great limitations, which leads to the problem that it is difficult to meet the subsequent market manufactured engines.
