Description

Technical Field

[0001] The utility model belongs to the field of automobile manufacturing and relates to the installation of license plates of five different structures in two front bumpers with different product shapes. Background Art

[0002] The current installation process for license plates with five different structures on two different front bumpers is as follows: parts welding - license plate installation - spoiler assembly - standard parts assembly - visual inspection - final inspection. This method allows for 10 different configurations, delivered on a just-in-time (JIT) basis. To ensure timely delivery, the contingency plan requires a finished goods inventory of 100 sets for each of the 10 configurations. Based on the existing process, this would require a finished goods inventory of 1,000 sets. Furthermore, this contingency plan requires the investment of 250 new racks for storing finished goods, requiring 1,000 square meters of storage space and approximately one million RMB in capital expenditure. Therefore, it is necessary to address the high finished goods inventory levels associated with the existing process. Summary of the Invention

[0003] In view of the above-mentioned technical problems and defects, the purpose of the utility model is to provide a flexible tooling for installing license plates. The flexible tooling has a simple overall structure. After adopting the tooling, the license plate can be installed before the final inspection of delivery. The existing installation process flow of license plates with five different structures on the front bumper is changed, and the number of finished product inventory for the emergency supply plan is reduced from 1,000 sets to 200 sets, which greatly saves floor space and avoids quality problems such as dust accumulation caused by long-term stagnation of finished products.

[0004] In order to achieve the above purpose, the technical solution adopted by the present utility model is:

[0005] A flexible tooling for installing a license plate, comprising a license plate positioning frame, an oblique L-shaped bracket, a positioning column, and a protective block; wherein the license plate positioning frame comprises a main frame, the interior of the main frame is processed with a first positioning and mounting area, the first positioning and mounting area matches the EU license plate and is used to install the EU license plate; the bottom surface of the first positioning and mounting area is processed with a first positioning and mounting groove, the bottom surface of the first positioning and mounting groove and the top surface of the first positioning and mounting area form a second positioning and mounting area, the second positioning and mounting area matches the CN license plate and is used to install the CN license plate; the top surface of the first positioning and mounting area is processed with a second positioning and mounting groove, the top surface of the second positioning and mounting groove and the bottom surface of the first positioning and mounting groove form a third positioning and mounting area; the third positioning and mounting area matches the JP license plate and is used to install the JP license plate Plate; the main frame is provided with two first positioning blocks and two second positioning blocks at a position close to the bottom surface of the first positioning mounting groove; the first positioning block and the second positioning block are rotatably connected to the main frame, and the two second positioning blocks are arranged on the inner sides of the two first positioning blocks. 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 mounting groove and the top surface of the second positioning mounting groove form a fourth positioning mounting area, and the fourth positioning mounting area matches the AU license plate for installing the AU license plate; the inner side walls of the two second positioning blocks are provided with an L-shaped positioning groove near the upper end. After the second positioning block is rotated upward, a fifth positioning mounting area is formed between the two L-shaped positioning grooves. The fifth positioning mounting area matches the CO license plate for installing the CO license plate;

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

[0007] Protection blocks are provided on both sides of the main frame at a side close to the front bumper, and a surface of the protection block in contact with the front bumper is a structure that imitates the contact portion of the front bumper.

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

[0009] As a preferred embodiment of the present invention, the first positioning block, the second positioning block and the main frame are connected via hinges.

[0010] As a preferred embodiment of the present invention, the oblique L-shaped bracket is installed on the main frame by bolts. The oblique L-shaped bracket includes a vertical connection part fixedly connected to the main frame, an oblique connection part fixedly connected to the vertical connection part, and a horizontal connection part connected to the oblique connection part.

[0013] Compared with the prior art, the advantages and beneficial effects of the present invention are:

[0014] (1) The flexible tooling provided by the present invention is capable of designing a 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, and cleverly utilizes rotating positioning blocks and processed positioning and installation grooves to flexibly transform different positioning and installation areas, so that 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.

[0015] (2) The inclined L-shaped bracket on the flexible tooling provided by the utility model is installed on the main frame in a detachable manner. It can be used for two 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, ensuring the accuracy of the installation position.

[0016] (3) After adopting the flexible tooling provided by the utility model, the license plate can be installed before the final inspection of delivery (parts welding - deflector assembly - standard parts assembly - visual inspection - installation of license plate - final inspection), which changes the existing installation process flow of license plates with 5 different structures for front bumpers, and reduces the number of finished product inventory for the supply emergency plan from 1,000 sets to 200 sets, greatly saving the floor space and avoiding quality problems such as dust accumulation caused by the long-term stagnation of finished products.

[0017] (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.
