[0023] It should be noted that, since it is difficult to quickly tighten the front cover and the car engine room by bolts when installing the existing car front cover, the installation efficiency is low. In this embodiment, the front cover bolt tightening tool is positioned between the engine room and the car front cover, and the bolts are tightened in the hood closed state, that is, the working position and the assembly position are unified. After the bolts are tightened, the assembly quality is good, the consistency is good, and the efficiency is high. There is no need to repeatedly adjust the assembly position, and the production efficiency is high.

[0024] Specifically, in the present embodiment, the present scheme mainly comprises a first locating pin 3, a first supporting block 4, a second supporting block 6, a third supporting block 8, a fourth supporting block 9 and a second locating pin 10. When in use, a tool for tightening the front cover bolt is customized according to the internal structure of the engine room of the automobile. When tightening the front cover bolt, the tool for tightening the front cover bolt is first placed in the engine room, and the first supporting block 4 and the second supporting block 6 are supported in the engine room. The first locating pin 3 is inserted into the locating gap of the engine room itself to realize the positioning and support of the tool for tightening the front cover bolt in the front engine room of the automobile. The nut on the front cover bolt used for connecting and fixing is inserted into the nut The nut limiting groove 14 limits the bolt, and then the front hood of the car is placed on the tooling for tightening the front hood bolts. The third support block 8 and the fourth support block 9 support the front hood of the car. The second positioning pin 10 is inserted into the positioning space of the front hood of the car to achieve support and positioning between the front hood of the car and the tooling for tightening the front hood bolts. At this time, the bolt is aligned with the hinge on the front hood, and the reduction motor 12 is started. The reduction motor 12 drives the nut sleeve 13 to rotate through the output end on one side thereof, and the bolts on the nut sleeve 13 rotate synchronously. The bolts are screwed into the hinge of the front hood to achieve the connection between the front hood and the car, and the assembly of the front hood is completed.
