Description

Technical Field

[0001] The utility model relates to the technical field of front covers, in particular to a front cover positioning fixture. Background Art

[0002] The cover in front of the car is called the hood. The hood is made of rubber foam and aluminum foil. While reducing engine noise, it can also isolate the heat generated by the engine at work, effectively protect the paint on the surface of the hood, and prevent aging. The engine works in a high temperature, high pressure and flammable environment. There is a risk of explosion or combustion, leakage and other accidents due to overheating or accidental damage to the original parts. The hood can effectively block the damage caused by the explosion and act as a protective shield. It effectively blocks the air and prevents the spread of flames, reducing the risk and loss of combustion. When the driver is driving the car, the forward line of sight and the reflection of natural light are crucial for the driver to correctly judge the road and the conditions ahead. The shape of the hood can effectively adjust the direction and form of the reflected light, thereby reducing the impact of light on the driver. When processing the front cover, it is necessary to use a fixture to position the front cover.
