After the two first positioning blocks are rotated upward and the second positioning blocks are rotated downward, the inner side surfaces of the two first positioning blocks and the bottom surface of the first positioning and mounting groove and the top surface of the second positioning and mounting groove form a fourth positioning and mounting area, and the fourth positioning and mounting area matches the AU license plate and is used to install the AU license plate; the inner side walls of the two second positioning blocks are provided with L-shaped positioning grooves at a position close to the upper end. After the second positioning block is rotated upward, a fifth positioning and mounting area is formed between the two L-shaped positioning grooves. The fifth positioning and mounting area matches the CO license plate and is used to install the CO license plate;

[0006] An oblique L-shaped bracket is provided at the upper end of the main frame, and a positioning column matching the positioning hole of the front bumper is provided at the upper end of the oblique L-shaped bracket;

[0007] Protection blocks are arranged on both sides of the main frame at one side close to the front bumper, and the side of the protection block in contact with the front bumper is a structure conforming to the contact part of the front bumper.

[0008] As a preferred embodiment of the present invention, both sides of the main frame are provided with hand-held handles on the side away from the front bumper, and the hand-held handles are fixed to the license plate positioning frame by bolts.

[0017] Compared with the prior art, the advantages and beneficial effects of the present invention are:

[0018] (1) The flexible tooling provided by the present invention designs the license plate positioning frame by itself. The license plate positioning frame utilizes the outer contour of the license plate to design different positioning and installation areas. The rotating positioning blocks and processed positioning and installation grooves are cleverly utilized to flexibly transform the different positioning and installation areas, so that the different positioning and installation areas are interrelated but do not affect each other's positioning and installation, thereby distinguishing five different license plates and achieving the purpose of preventing position errors. This method has a simple structure and can realize the installation and positioning of five different license plates.

[0019] (2) The inclined L-shaped bracket on the flexible tooling provided by the present invention is installed on the main frame in a detachable manner, and can be applied to two types of skins with different shapes. The accuracy of the relative position is determined by the positioning column, and the positions of five types of license plates are determined by the contour of the license plate, thereby ensuring the accuracy of the installation position.

[0020] (3) After adopting the flexible tooling provided by the present invention, the license plate can be installed before the final inspection of delivery (parts welding - guide plate assembly - standard parts assembly - visual inspection - license plate installation - final inspection), which changes the existing installation process of license plates with five different structures of the front bumper, and reduces the number of finished product inventory of the emergency supply plan from 1,000 sets to 200 sets, greatly saving floor space and avoiding quality problems such as dust accumulation caused by long-term stagnation of finished products.

[0021] (4) The use of the flexible tooling provided by the present invention can save 800 pieces of finished product inventory, about 800,000 yuan of funds occupied by the products (the unit price of the finished product is 1,000 yuan*800 products=about 800,000 yuan), 200 material racks (one material rack can hold 4 products, saving 800 products, a total of 200 material racks), and the total savings are greater than 1 million RMB.
