Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a plastic spraying fixture for an automobile front cover. Background Art

[0002] Automobile hood processing is a complex and delicate process involving multiple steps and techniques. In order to increase the aesthetics and corrosion resistance of the hood, surface treatment is required. Common surface treatment methods include spraying, electroplating, anodizing, etc. These treatments can improve the appearance quality, corrosion resistance and wear resistance of the hood.

[0003] A Chinese patent with the publication number CN217664051U discloses a clamp for spraying plastic on traffic parts, including a lifting support rod, a protection box and a movable rod. The bottom of the lifting support rod is installed on the bottom plate, and the upper end of the lifting support rod is installed with a mounting seat, and the inside of the mounting seat is interspersed with a movable rod. The driving motor is installed on the top plate of the upper end of the lifting support rod through the motor fixing seat. The front end of the movable rod is installed with a clamping assembly, and the lower end of the clamping assembly is provided with a protection box, and the protection box is fixed on the bottom plate. The clamp for spraying plastic on traffic parts is electrically adjusted to improve work efficiency, and can also adapt to the clamping of metals of different sizes; the part to be sprayed is placed in the middle of the clamping mechanism and transported to the middle of the clamping mechanism through the suction cup, and the driving motor is started to drive the two movable rods to move towards each other to complete the clamping work of the clamping plate on the part to be sprayed. The clamping work is electrically adjusted to improve work efficiency.

[0004] As mentioned above, the patent provides a clamp for spraying plastic on traffic parts. Although it can adapt to the clamping of metals of various sizes, and the motor drives the two movable rods to move toward each other to complete the clamping work of the clamping plate on the sprayed parts, and the electric adjustment improves the work efficiency, it uses a motor to control the clamping, and the accuracy cannot be controlled. It is easy to over-clamp during clamping, resulting in deformation of the car hood. At the same time, it cannot be adjusted after clamping, resulting in the need to constantly adjust the spray nozzle during spraying. The overall efficiency of the spraying operation needs to be improved. Utility Model Content
