Description

Technical Field

[0001] This utility model relates to the field of vehicle assembly technology, and more specifically to an assembly tooling. Background Technology

[0002] The gaps and staggered sections in the exterior design of a new model affect both aesthetic evaluation and functional requirements.

[0003] The vehicle includes a body-in-white and fenders and lower outer front door panels mounted on the body-in-white. The body-in-white forms the cab, with door frames on both sides for mounting the doors. A panel mounting plate is located at the lower part of each door frame, and the lower outer front door panel covers this mounting plate. A fender mounting plate is located at the front of each door frame, and the fender covers this mounting plate. The fender is connected to the mounting plate via fender brackets. The fender brackets and the mounting plate are connected by bolts.

[0004] However, during the assembly process, it is difficult to determine the position of the fender bracket on the fender mounting plate, resulting in a height difference between the fender and the lower outer front door trim panel after installation, which affects the vehicle's decorative effect. Utility Model Content

[0005] The purpose of this utility model is to provide an assembly fixture to solve the problem that the position of the fender bracket on the fender mounting plate is difficult to determine, resulting in a height difference between the fender and the lower outer front door trim panel after installation, which affects the decorative effect of the vehicle.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] According to a first aspect of this application, this application provides an assembly fixture, which includes: a base; a first positioning post, the first positioning post being disposed on the mounting surface of the base, the center line of the first positioning post being perpendicular to the mounting surface; a first positioning pin being disposed on the first positioning post, the first positioning post being used to abut against a fender bracket, and the first positioning pin being used to pass through a first positioning hole on the fender bracket; and a second positioning post, the second positioning post being disposed on the mounting surface, the center line of the second positioning post being perpendicular to the mounting surface; a second positioning pin being disposed on the second positioning post, the second positioning post being used to abut against a guard plate mounting plate, and the second positioning pin being used to pass through a second positioning hole on the guard plate mounting plate.

[0008] With the above configuration, both the first and second positioning posts are mounted on the mounting surface, and their center lines are perpendicular to the mounting surface. The first positioning post has a first positioning pin, and the second positioning post has a second positioning pin. During fender bracket assembly, the first positioning post abuts against the fender bracket, and the first positioning pin passes through the first positioning hole on the fender bracket. The second positioning post abuts against the skid plate mounting plate, and the second positioning pin passes through the second positioning hole on the skid plate mounting plate. This limits the distance between the fender bracket and the skid plate mounting plate, as well as the position of the fender bracket along the vehicle width direction, thereby improving the positional accuracy of the fender bracket. When the fender is mounted on the fender bracket, since the distance between the fender bracket and the skid plate mounting plate, and the position of the fender bracket along the vehicle width direction are determined, the distance between the fender and the lower outer skid plate of the front door along the vehicle width direction is reduced or eliminated (reducing or eliminating the step difference between the fender and the lower outer skid plate of the front door), improving the vehicle's decorative effect.

[0009] In one possible implementation, there are multiple first positioning posts, which are spaced apart. Each first positioning post is provided with a first positioning pin, and each first positioning pin passes through a first positioning hole. There are also multiple second positioning posts, which are spaced apart. Each second positioning post is provided with a second positioning pin, and each second positioning pin passes through a second positioning hole.

[0010] Based on the aforementioned technical means, by setting multiple first positioning posts, each equipped with a first positioning pin, rotation of the fender bracket relative to the assembly fixture can be prevented. Similarly, by setting multiple second positioning posts, each equipped with a second positioning pin, rotation of the assembly fixture relative to the skid plate mounting plate can be prevented. This further restricts the position of the fender bracket, improves its positional accuracy, and consequently improves the positional accuracy of the fender, thus enhancing the vehicle's aesthetic appeal.

[0011] In one possible implementation, the assembly fixture further includes a magnet disposed on a base, the magnet being used to attract the fender mounting plate and / or the guard plate mounting plate.

[0012] According to the above-mentioned technical means, when in use, the magnet attracts the fender mounting plate and / or the guard plate mounting plate, which can keep the first positioning post in contact with the fender bracket and the second positioning post in contact with the guard plate mounting plate, thereby preventing the assembly tooling from falling off and making it easier to fix the fender bracket to the fender mounting plate.

[0013] In one possible implementation, the assembly fixture further includes a first clamping device disposed on the base, the first clamping device being used to clamp the protective plate mounting plate.

[0014] Based on the aforementioned technical means, the first clamping device can adapt to the assembly requirements of guard plate mounting plates and fender mounting plates of different specifications and shapes, enhancing the versatility and applicability of the tooling and reducing tooling costs; at the same time, precise positioning ensures that the relative positions between the guard plate mounting plate, assembly tooling, and fender mounting plate are accurate, which helps to improve the assembly accuracy and consistency of the entire product.

[0015] In one possible implementation, the first clamping device includes a first link, a second link, a third link, a first clamping head, and a second clamping head. One end of the first link is hinged to the base, and the first clamping head is disposed at the other end of the first link. One end of the second link is hinged to the first link, and the other end of the second link is provided with a handle. One end of the third link is hinged to the base, and the other end of the third link is hinged to the second link. The second clamping head is disposed on the base and faces the first clamping head. When the second link rotates to a position perpendicular to the first link, the first clamping head and the second clamping head clamp the protective plate mounting plate.

[0016] Based on the above-mentioned technical means, operators can achieve greater clamping force by slightly rotating the handle and utilizing the lever principle, thereby reducing the physical strength required for operation. This is especially suitable for long-term repetitive assembly work and improves work efficiency.

[0017] In one possible implementation, the assembly fixture further includes a second clamping device disposed on the base, the second clamping device being used to clamp the fender mounting plate.

[0018] Based on the aforementioned technical means, the second clamping device can adapt to the assembly requirements of guard plate mounting plates and fender mounting plates of different specifications and shapes, enhancing the versatility and applicability of the tooling and reducing tooling costs; at the same time, precise positioning ensures that the relative positions between the guard plate mounting plate, assembly tooling, and fender mounting plate are accurate, which helps to improve the assembly accuracy and consistency of the entire product.

[0019] In one possible implementation, the second clamping device includes a fourth link, a fifth link, a sixth link, a third clamping head, and a fourth clamping head. One end of the fourth link is hinged to the base, and the third clamping head is disposed at the other end of the fourth link. One end of the fifth link is hinged to the fourth link, and the other end of the fifth link is provided with a handle. One end of the sixth link is hinged to the base, and the other end of the sixth link is hinged to the fifth link. The fourth clamping head is disposed on the base and faces the third clamping head. When the fifth link rotates to a position perpendicular to the fourth link, the third clamping head and the fourth clamping head clamp the protective plate mounting plate.

[0020] Based on the above-mentioned technical means, operators can achieve greater clamping force by slightly rotating the handle and utilizing the lever principle, thereby reducing the physical strength required for operation. This is especially suitable for long-term repetitive assembly work and improves work efficiency.

[0021] In one possible implementation, the assembly fixture further includes a shim disposed on the mounting surface, the shim being used to abut against the guard plate mounting plate and / or the fender bracket.

[0022] Based on the above technical means, when the component design is temporarily adjusted, there is no need to modify the base; simply changing the thickness of the shim is sufficient for quick adaptation, reducing tooling modification costs.

[0023] In one possible implementation, the gasket includes a first gasket and a second gasket, the first gasket abutting against the fender mounting plate and the second gasket against the fender bracket.

[0024] Based on the above technical means, the first and second shims can realize the adjustment of the positioning block in the X / Y / Z directions to meet the assembly requirements, while reserving the possibility of later debugging.

[0025] In one possible implementation, the base further includes an outer surface opposite to the mounting surface, and a gripping portion is provided on the outer surface.

[0026] Based on the aforementioned technical means, the grip provides the user with a clear point of force application, allowing for easy manual picking up of tooling by grasping, lifting, or pushing the base. Attached Figure Description

Detailed Implementation

[0037] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0038] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0039] With the development of the automotive industry, vehicles have become widely used. Vehicles can be electric vehicles, hybrid vehicles, gasoline vehicles, or solar-powered vehicles, among others. Electric vehicles are powered by an electric motor and also have a battery connected to the motor to supply power. Hybrid vehicles can include a gasoline engine and an electric motor, which can power the vehicle simultaneously or alternately. Gasoline vehicles consist of a gasoline engine and a transmission, with the gasoline engine providing power through the transmission. Solar-powered vehicles utilize solar energy to generate electricity, which is then used to power the vehicle via an electric motor.

[0040] The vehicle in this application embodiment can also be a vehicle of different types. For example, the vehicle provided in this application embodiment can be a sedan, a sport utility vehicle (SUV), or a multi-purpose vehicle (MPV), etc.

[0041] In some embodiments, see Figure 1 and combined Figure 2 The vehicle in this application includes a body-in-white and fenders 5 and front door lower outer guard plates 6 mounted on the body-in-white; the body-in-white forms a cab 4, and along the width direction of the vehicle, the cab 4 has door frames on both sides for mounting doors; a guard plate mounting plate 2 is provided at the lower part of the door frame, and the front door lower outer guard plate covers the guard plate mounting plate 2; a fender mounting plate 3 is provided at the front of the door frame, the fender 5 covers the fender mounting plate 3, and the fender 5 is connected to the fender mounting plate 3 through a fender bracket 1, and the fender bracket 1 and the fender mounting plate 3 are connected by bolts.

[0042] Please refer to Figure 2 and Figure 3 This application provides an assembly fixture for installing the fender bracket 1 in the above embodiment. The assembly fixture includes a base 101 and a first positioning post 102. The base 101 can be in a regular shape such as a plate or column. Of course, the base 101 can also be in other irregular shapes. The base 101 has a mounting surface, and the first positioning post 102 is disposed on the mounting surface. The center line of the first positioning post 102 can be perpendicular to the mounting surface. For example, the first positioning post 102 and the base 101 can be connected by welding, bolts, or other methods. Of course, the first positioning post 102 can also be cast to form an integral structure with the base 101. This application does not limit this.

[0043] In the above implementation, a first positioning pin 201 is provided on the first positioning post 102. The first positioning pin 201 can be located at the end of the first positioning post 102 away from the base 101, and the center line of the first positioning pin 201 can be set parallel to the center line of the first positioning post 102.

[0044] The assembly fixture in this embodiment further includes a second positioning post 103, which is disposed on the mounting surface and whose centerline is perpendicular to the mounting surface. For example, the second positioning post 103 and the base 101 can be connected by welding, bolting, or other methods. Alternatively, the second positioning post 103 can be cast to form an integral structure with the base 101; this embodiment does not impose any limitations on this. A second positioning pin 301 is provided on the second positioning post 103, and the centerline of the second positioning pin 301 can be parallel to the centerline of the second positioning post 103.

[0045] When installing the fender bracket 1, the first positioning post 102 abuts against the fender bracket 1, and the first positioning pin 201 passes through the first positioning hole 11 on the fender bracket 1; simultaneously, the second positioning post 103 abuts against the fender mounting plate 2, and the second positioning pin 301 passes through the second positioning hole 22 on the fender mounting plate 2. The first positioning post 102 and the second positioning post 103 restrict the position between the fender bracket 1 and the fender mounting plate 2, thereby improving the positional accuracy between the fenders 5. Afterwards, the fender bracket 1 is installed on the fender mounting plate 3 by bolt connection to achieve fixation of the fender bracket 1. For example, corresponding mounting holes are provided on the fender bracket 1 and the fender mounting plate 3, and bolts and positioning nuts 222 are used to fasten the two together.

[0046] It is understood that the first positioning hole 11 on the fender bracket 1 can be a hole in the fender bracket 1 for connecting the fender 5. That is, the fender 5 is connected to the fender 5 bracket by a bolt passing through the first positioning hole 11 to achieve the fixation of the fender 5. Of course, the first positioning hole 11 can also be a hole separately provided on the fender bracket 1 for positioning, and this embodiment does not limit this. Similarly, the second positioning hole 22 on the guard plate mounting plate 2 can also be a hole for installing the front door lower outer guard plate 6. That is, the front door lower outer guard plate 6 can be connected to the guard plate mounting plate 2 by a bolt passing through the second positioning hole 22. Of course, the second positioning hole 22 can also be a hole separately provided on the guard plate mounting plate 2 for positioning.

[0047] The assembly fixture provided in this application has a first positioning post 102 and a second positioning post 103 both mounted on the mounting surface. The center lines of the first positioning post 102 and the second positioning post 103 are perpendicular to the mounting surface. A first positioning pin 201 is provided on the first positioning post 102, and a second positioning pin 301 is provided on the second positioning post 103. When assembling the fender bracket 1, the first positioning post 102 abuts against the fender bracket 1, and the first positioning pin 201 passes through the first positioning hole 11 on the fender bracket 1. The second positioning post 103 abuts against the guard plate mounting plate 2, and the second positioning pin 301 passes through the second positioning hole 22 on the guard plate mounting plate 2. This limits the distance between the fender bracket 1 and the guard plate mounting plate 2, as well as the position of the fender bracket 1 along the vehicle width direction, thereby improving the positional accuracy of the fender bracket 1. When the fender 5 is installed on the fender bracket 1, the distance between the fender bracket 1 and the guard plate mounting plate 2, as well as the position of the fender bracket 1 along the vehicle width direction, can be determined, thereby reducing or eliminating the distance between the fender 5 and the lower outer guard plate 6 of the front door along the vehicle width direction (reducing or eliminating the step difference between the fender 5 and the lower outer guard plate 6 of the front door), and improving the decorative effect of the vehicle.

[0048] In some embodiments, see Figure 3 and combined Figure 4 There are multiple first positioning posts 102, spaced apart, and each first positioning post 102 is provided with a first positioning pin 201. Correspondingly, the fender bracket 1 has multiple first positioning holes 11 spaced apart, and each first positioning pin 201 passes through a first positioning hole 11. Similarly, there are multiple second positioning posts 103, spaced apart, and each second positioning post 103 is provided with a second positioning pin 301. Correspondingly, the guard plate mounting plate 2 has multiple second positioning holes 22 spaced apart, and each second positioning pin 301 passes through a second positioning hole 22.

[0049] By setting multiple first positioning posts 102, each with a first positioning pin 201, rotation of the fender bracket 1 relative to the assembly fixture can be prevented. Similarly, by setting multiple second positioning posts 103, each with a second positioning pin 301, rotation of the assembly fixture relative to the skid plate mounting plate 2 can be prevented. This further restricts the position of the fender bracket 1, improves its positional accuracy, and consequently improves the positional accuracy of the fender 5, thus enhancing the vehicle's aesthetic appeal.

[0050] For example, there can be two first positioning posts 102. During assembly, there are two positioning nuts 222 corresponding to the lower fender bracket 1. The assembled first positioning posts fit the surface of the fender bracket 1. There can be three second positioning posts 103. They are close to the guard plate mounting plate 2. During assembly, two of the second positioning pins 301 on the edge of the base 101 are respectively assembled to the round hole and the oblong hole on the guard plate mounting plate 2. The round hole and the oblong hole play the positioning and limiting functions, respectively, to ensure that the assembly tool fits the surface of the guard plate mounting plate and the fender mounting plate and the assembly is stable.

[0051] For example, the diameter of the first locating pin 201 can be Ф4mm-Ф6mm (such as Ф4mm, Ф5.8mm, Ф6mm, etc.), and the diameter of the second locating pin 301 can be Ф6mm-Ф9mm (such as 6mm, Ф7.9mm, Ф8mm, etc.).

[0052] In some embodiments, see Figure 3 and combined Figure 2 The assembly fixture also includes a magnet 104, which is disposed on the base 101 and is used to attract the fender mounting plate 3 and / or the guard plate mounting plate 2.

[0053] In the above implementation, when in use, the magnet 104 attracts the fender mounting plate 3 and / or the guard plate mounting plate 2, which can keep the first positioning post 102 in contact with the fender bracket 1 and the second positioning post 103 in contact with the guard plate mounting plate 2, thereby preventing the assembly tooling from falling off and making it easier to fix the fender bracket 1 on the fender mounting plate 3.

[0054] In some embodiments, see Figure 3 and combined Figure 2 The assembly fixture also includes a first clamping device 105, which is mounted on the base 101 and is used to clamp the protective plate mounting plate 2.

[0055] In the above implementation, the first clamping device 105 is equipped with a spring to adapt to the assembly requirements of the guard plate mounting plate 2 and the fender mounting plate 3 of different specifications and shapes, thereby enhancing the versatility and applicability of the tooling and reducing tooling costs. While providing clamping force, the first clamping device 105 can also play a role in precise positioning, ensuring that the relative positions between the guard plate mounting plate 2, the assembly tooling, and the fender mounting plate 3 are accurate, laying the foundation for the subsequent assembly of the fender bracket 1, and helping to improve the assembly accuracy and consistency of the entire product.

[0056] In some embodiments, see Figure 3 and combined Figure 2The first clamping device 105 includes a first connecting rod 501, a second connecting rod 502, a third connecting rod 503, a first clamping head 504, and a second clamping head 505. One end of the first connecting rod 501 is hinged to the base 101, and the first clamping head 504 is disposed at the other end of the first connecting rod 501. One end of the second connecting rod 502 is hinged to the first connecting rod 501, and the other end of the second connecting rod 502 is provided with a handle 506. One end of the third connecting rod 503 is hinged to the base 101, and the other end of the third connecting rod 503 is hinged to the second connecting rod 502. The second clamping head 505 is disposed on the base 101 and faces the first clamping head 504. When the second connecting rod 502 rotates to a position perpendicular to the first connecting rod 501, the first clamping head 504 and the second clamping head 505 clamp the protective plate mounting plate 2.

[0057] In the above implementation, a handle 506 is provided on the second link 502 of the first clamping device 105, forming a lever transmission system with the first link 501 and the third link 503. Please refer to [link to relevant documentation]. Figure 6 and combined Figure 3 The operator can rotate the handle 506 slightly, causing the handle 506 to rotate towards the operator, which in turn drives the first link 501 and the second link 502 upwards. The operator can also rotate the handle 506 in the opposite direction of the operator, causing the first link 501 and the second link 502 downwards. By utilizing the lever principle, a large clamping force can be achieved, reducing the physical strength required for operation. This is especially suitable for long-term repetitive assembly work and improves work efficiency. The clamping action can be completed by rotating the handle to make the second link 502 perpendicular to the first link 501. Compared with traditional bolt fastening or snap-fit ​​connection, the fixing time of the guard plate mounting plate 2 is greatly shortened.

[0058] In some embodiments, see Figure 3 and combined Figure 2 The assembly fixture also includes a second clamping device 106, which is mounted on the base 101 and is used to clamp the fender mounting plate 3.

[0059] In the above implementation, the second clamping device 106 is equipped with a spring to adapt to the assembly requirements of the guard plate mounting plate 2 and the fender mounting plate 3 of different specifications and shapes, which enhances the versatility and applicability of the tooling and reduces the tooling cost. While providing clamping force, the second clamping device 106 can also play a role in precise positioning, ensuring that the relative positions between the guard plate mounting plate 2, the assembly tooling, and the fender mounting plate 3 are accurate, laying the foundation for subsequent processing steps and helping to improve the assembly accuracy and consistency of the entire product.

[0060] In some embodiments, see Figure 3 and combined Figure 2The second clamping device 106 includes a fourth link 601, a fifth link 602, a sixth link 603, a third clamping head 604, and a fourth clamping head 605. One end of the fourth link 601 is hinged to the base 101, and the third clamping head 604 is disposed at the other end of the fourth link 601. One end of the fifth link 602 is hinged to the fourth link 601, and the other end of the fifth link 602 is provided with a handle 506. One end of the sixth link 603 is hinged to the base 101, and the other end of the sixth link 603 is hinged to the fifth link 602. The fourth clamping head 605 is disposed on the base 101 and faces the third clamping head 604. When the fifth link 602 rotates to a position perpendicular to the fourth link 601, the third clamping head 604 and the fourth clamping head 605 clamp the protective plate mounting plate 2.

[0061] In the above implementation, the fifth link 602 of the second clamping device 106 is equipped with a handle 506, forming a lever transmission system with the fourth link 601 and the sixth link 603. Please refer to [link to relevant documentation]. Figure 7 and combined Figure 3 The operator can achieve a large clamping force by slightly rotating the handle 506. The handle 506 rotates towards the operator, driving the fourth link 601 and the fifth link 602 upward. The handle 506 rotates in the opposite direction to the operator, driving the fourth link 601 and the fifth link 602 downward. The lever principle can be used to achieve a large clamping force, reducing the physical strength required for operation. It is especially suitable for long-term repetitive assembly work and improves work efficiency. The clamping action can be completed by rotating the handle to make the fifth link 602 perpendicular to the fourth link 601. Compared with traditional bolt fastening or buckle connection, the fixing time of the guard plate mounting plate 2 is greatly shortened.

[0062] In some embodiments, see Figure 3 and combined Figure 2 The assembly fixture also includes a gasket, which is placed on the mounting surface and is used to abut against the guard plate mounting plate 2 and / or the fender bracket 1.

[0063] In the above implementation, when the mounting plate 2 and fender bracket 1 of different types of vehicles are used in the assembly tooling, there is no need to modify the base 101. The tooling can be quickly adapted by simply changing the thickness of the shim, thereby reducing the tooling modification cost.

[0064] In some embodiments, see Figure 3 and combined Figure 2 The gasket includes a first gasket and a second gasket. The first gasket abuts against the guard plate mounting plate 2, and the second gasket abuts against the fender bracket 1.

[0065] In the above implementation, a first shim is set at the position of the first positioning post 102, a second shim is set at the position of the second positioning post 103, and a shim adjustment base 107 is set at the position where the shims are placed. A 3mm gap is reserved between the first positioning post 102 and the second positioning post 103 in the X and Y directions to realize the adjustment of the first positioning post 102 and the second positioning post 103 in the X / Y / Z directions, meet the assembly requirements, and reserve the possibility of later debugging.

[0066] In some embodiments, see Figure 5 The base 101 also includes an outer surface opposite to the mounting surface, and a gripping part 108 is provided on the outer surface.

[0067] In the above implementation, the gripping part 108 provides the user with a clear point of force application, and the user can grasp, lift or push the base 101 by hand to facilitate manual picking up of the tooling.

[0068] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
