Description

Technical Field

[0001] This utility model relates to an assembly contouring tooling. Background Technology

[0002] The field of assembly contour tooling has been constantly innovating along with the development of the manufacturing industry. In the early days, due to technological limitations, tooling was mostly simple and general-purpose, which could only meet basic assembly needs. When dealing with complex and irregularly shaped parts, the positioning accuracy was poor and the efficiency was low.

[0003] With technological advancements, modern industry demands ever-increasing precision and quality from its products, particularly in aerospace and precision machinery. This has spurred the development of high-precision and customized assembly tooling. Companies are developing contour-following tooling that conforms to the complex contours of parts. For example, Guizhou Aerospace Fenghua's contour-following tooling for irregularly shaped thin-walled parts significantly reduces machining errors and improves stability and ease of operation. Simultaneously, the integration of intelligent and automated technologies, such as robotic arms and vibratory feeders, enhances assembly quality and efficiency while reducing labor costs and intensity.

[0004] Currently, in the field of assembly contour tooling, existing technologies face several pressing issues. Taking automotive tailgate assembly as an example, traditional manual assembly lines heavily rely on operator experience, making process stability difficult to guarantee. While tailgate assembly fixtures improve assembly precision and consistency to some extent, they still have significant drawbacks. When the gap between the tailgate edging and the side panel is too small, the tooling reference block is easily squeezed by the side panel, causing the assembly module to flip and affecting positioning accuracy. Moreover, with increasing demands for vehicle lightweighting and styling, tailgate sheet metal outer panels often have exterior trim pieces installed to match the side panel. During the tailgate assembly stage of the body-in-white, since there is no direct surface match between the tailgate and the side panel, this fixture cannot determine whether the tailgate is aligned after assembly in the overall vehicle exterior trim matching state.

[0005] In the assembly of decorative cover plate clips, traditional methods involve direct manual assembly or simplified assembly. Manual assembly uses a rubber hammer to tap the clips into place, while simplified assembly uses contour blocks to fix the parts before manual assembly. Both methods are prone to improper clip installation and result in high labor intensity for workers. Existing automated clip assembly equipment is not only limited in number but also generally has a low level of automation, leading to low production efficiency and high production costs. Furthermore, the placement and positioning of parts are not precise enough, easily damaging the product surface during assembly. The equipment also lacks an electronic control unit, limiting parameter adjustment options and providing insufficient safety protection, particularly for operators, by lacking safety devices.

[0006] For coating operations on the outer surface of irregularly shaped tooling, such as the contouring and limiting tooling disclosed in announcement number CN19901179U, although the tooling is limited to facilitate pre-milling of irregularly shaped tooling, it cannot meet the requirement that coating operations on both sides of the tooling do not affect each other. That is, coating particles tend to flow from the front to the back of the tooling during spraying, and it is difficult to adapt to the clamping requirements of different contouring tooling.

[0007] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a new type of assembly contour tooling with a new structure, which would have greater industrial application value. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0021] Example like Figure 1 and Figure 2As shown, an assembly contouring fixture includes a fixed base plate 1. A first fixing plate 2, a second fixing plate 3, and a third fixing plate 4 for placing and fixing a product are connected to the fixed base plate 1. The fixed base plate 1 has evenly arranged connecting holes. The first fixing plate 2, the second fixing plate 3, and the third fixing plate 4 are all bolted to the connecting holes. A first positioning block 5 is connected to one side of the first fixing plate 2, which is used to position and fix the head of the product. A fixing pin hole 6 is provided on the first fixing plate 2 located at the first positioning block 5. A first moving block 7 is connected to the first fixing plate 2 adjacent to the first positioning block 5. A second moving block 8 and a third moving block 9 for fixing the middle part of the product are connected to the second fixing plate 3. The second moving block 8 and the third moving block 9 are opposite each other and have an adjustable spacing. A second positioning block 11 is connected to one side of the third fixing plate 4, which is used to fix the tail of the product. A fourth moving block 12 is connected to the third fixing plate 4 opposite to the second positioning block 11. A fifth moving block 13 is connected to the other side of the third fixing plate 4.

[0022] In this embodiment, the fixed base plate 1 is made of aluminum and has a thickness of 12 mm.

[0023] In this embodiment, the first fixing plate 2, the second fixing plate 3, and the third fixing plate 4 are all made of plastic steel. Plastic steel allows for better matching with the product shape, thus achieving precise fixing.

[0024] In this embodiment, a positioning pin 10 for positioning and fixing the product is connected to the fixing pin hole 6 to ensure accurate positioning and fixing of the product.

[0025] In this embodiment, the first fixing plate 2, the second fixing plate 3, and the third fixing plate 4 are each provided with an adjustment hole for matching their respective moving blocks. The moving blocks are connected to the corresponding adjustment holes by fixing bolts. The adjustment holes allow for more precise fixing of the product.

[0026] The working principle of this utility model is as follows: During installation, the product is placed on the first, second, and third fixed plates. The head of the product is fixed by the positioning pins, and the tail is positioned by the second positioning block. Then, the moving blocks are moved to achieve precise fixation of the product.

[0027] This utility model tooling is designed based on the shape of the product, eliminating the original fixed tooling. It uses a 12mm thick aluminum plate, 3 fixed blocks, 5 movable blocks, and a positioning pin to fix the product. The shape-following method can effectively prevent the plastic product from breaking due to excessive manual installation force. The movable blocks can effectively limit the slight differences caused by tolerance changes in the product.

[0028] Firstly, this utility model enables precise positioning of complex curved surface parts, ensuring that parts such as car tailgates can fit closely to their contours during assembly, avoiding uneven gaps between the parts and the side panels after assembly, and improving the dimensional accuracy and consistency of the parts assembly. Secondly, this utility model solves the problem of poor adaptability of non-contour tooling. Given that most non-contour tooling is general-purpose and cannot stably clamp irregularly shaped parts, this utility model has the ability to design clamping structures on demand, so that it can adapt to irregularly shaped parts of different shapes. For example, it can meet the stable clamping requirements during the coating operation of the outer surface of irregularly shaped tooling, prevent tooling displacement, and ensure the effect of subsequent processing or assembly.

[0029] Thirdly, this utility model achieves rapid positioning, reduces manual adjustment steps, improves assembly efficiency, and reduces labor costs and material loss costs.
