Description

Technical Field

[0001] This utility model relates to the field of motorcycle assembly tooling technology, specifically to an assembly tooling for a front support component of a motorcycle fuel tank. Background Technology

[0002] The front support component of a motorcycle fuel tank is a critical connecting part of the motorcycle frame. As one of the main load-bearing structures, it needs to bear most of the weight of the fuel tank and effectively transfer and distribute these loads to the main frame, ensuring the rigidity and stability of the connection point. The front support component typically consists of a support rod bent upwards at both ends and a first and second ring located at both ends of the support rod. Before use, these three dispersed components need to be precisely assembled and welded into a single unit. To ensure that the dimensions of the welded assembly meet design requirements and that the fuel tank can be accurately installed, precise positioning of each component is essential during the welding process. This ensures that the positions of each component remain fixed during welding, thereby guaranteeing welding quality and product precision, and preventing problems such as inaccurate welding positions and product scrap due to component movement or deformation.

[0003] Currently, publicly available or commonly used motorcycle fuel tank front support assembly tooling typically includes a base plate, on which a V-block or flat support is mounted to support the support rod, and it is clamped and fixed from above using a simple pressure plate or screws. For the positioning of the two rings, a common practice is to use two independent locating pins to position the first and second rings in height and lateral position respectively, and to use two independent stops or screws to axially limit the two rings from the outside to determine their welding position to the end of the support rod.

[0004] However, the current tooling design has significant drawbacks: First, using two independent locating pins and blocks to position and limit the two rings separately makes it difficult to guarantee the absolute coaxiality of the two rings and the accuracy and consistency of their axial distance, resulting in larger welding errors. Second, the limiting elements in the tooling are mostly independently and separately set, making the operation cumbersome, requiring each one to be installed, adjusted, and tightened individually, leading to low assembly efficiency. Furthermore, when welding one ring, the welding stress generated may cause the other ring to shift, and the traditional limiting method lacks an effective two-way interlocking mechanism to prevent this phenomenon, resulting in unstable welding quality. Utility Model Content

[0005] This utility model aims to provide a tooling assembly for the front support component of a motorcycle fuel tank to ensure the precise welding position of each component of the front support component.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A motorcycle fuel tank front support assembly includes a base plate. The base plate is provided with a positioning seat and a support rod limiting member for positioning and limiting the movement of a support rod. The positioning seat is located below the support rod. There are two sets of support rod limiting members, which are respectively located at both ends of the support rod. The support rod limiting members abut against the upwardly bent portion of the end of the support rod. The base plate is also provided with a positioning post and a ring limiting member for positioning a ring vertically, horizontally, and vertically. The positioning post is mounted on the base plate through the support seat. A first ring and a second ring are sequentially fitted onto the positioning post. The ring limiting member is rotatably mounted on the positioning seat. The ring limiting member is located between the first ring and the second ring, and its two sides abut against the first ring and the second ring respectively.

[0007] The principles and advantages of this scheme are: 1. Multiple positioning and limiting components are used to accurately position the support rod, the first ring, and the second ring in the lateral and longitudinal directions, respectively, which effectively prevents the support rod, the first ring, and the second ring from deviating from their precise welding positions during the welding process, and ensures the accuracy of the relative welding positions of the first ring, the second ring, and the end of the support rod.

[0008] 2. The placement, positioning, and clamping steps of the support rod, the first ring, and the second ring are clear, and the installation and disassembly of each positioning and limiting component are relatively simple, mostly involving plug-in operations, making the operation simple.

[0009] 3. The welding operation direction is indicated: the first ring is welded from the right side, and the second ring is welded from the left side. This ensures the welder has a good line of sight during welding and avoids interference between the welding torch and other parts of the tooling. Furthermore, during welding, the welding force may push the rings; the limiting block provides a solid support back for the first and second rings, ensuring that they remain firmly against the limiting block throughout the welding process and do not shift due to force, thus guaranteeing the accuracy of the final welding position.

[0010] Preferably, as an improvement, the positioning seat has two positioning protrusions arranged side by side, and the positioning protrusions are connected to the holes on the support rod.

[0011] Technical benefits: This solution, using the above-mentioned setup, utilizes the cooperation between holes and protrusions to quickly and accurately position the support rod in the required position, ensuring the installation accuracy of the support rod on the positioning seat and avoiding errors caused by placing it based on experience.

[0012] Preferably, as an improvement, the top of the positioning protrusion is provided with a guide slope along the circumferential direction.

[0013] Technical benefits: The above-mentioned design makes it easier for the holes of the guide support rod to fit into the positioning protrusion, reducing the difficulty of operation and improving assembly efficiency.

[0014] Preferably, as an improvement, the support rod limiting component includes a limiting rod and a fixed seat. The fixed seat is fixedly connected to the base plate. The fixed seat is provided with a contour groove for the limiting rod. The limiting rod is fixed in the contour groove by a pin. The upper part of the limiting rod is bent towards the support rod. The end of the limiting rod abuts against the upwardly bent part of the end of the support rod.

[0015] Technical effect: With the above-mentioned configuration, the limiting rod is fixed in the contour groove by a pin, which facilitates the installation and disassembly of the limiting rod. The contour groove can position the limiting rod to ensure the accuracy of the contact point between the limiting rod and the support rod.

[0016] Preferably, as an improvement, the positioning post includes a handle and a mounting rod arranged coaxially, the diameter of the handle being larger than the diameter of the mounting rod, and the mounting rod passing through two support seats arranged on the base plate in sequence for fixation.

[0017] Technical effect: The above-mentioned configuration of this solution makes it easy for the operator to hold and apply force to insert and pull out the positioning post. At the same time, the handle can also form a circumferential limit to prevent the positioning post from being excessively inserted into the support base.

[0018] Preferably, as an improvement, the support base has a circular hole, and a connecting sleeve that mates with the mounting rod is provided inside the circular hole.

[0019] Technical effect: The above-mentioned settings in this solution, with the rubber sleeve and the mounting rod having an interference fit, can effectively eliminate gaps and prevent the positioning column from shaking, rotating or moving axially during the welding process, thus ensuring positioning accuracy.

[0020] Preferably, as an improvement, the annular limiting component includes a limiting block and a rotating arm. The limiting block is a horizontally arranged U-shaped structure, and both ends of the U-shaped structure of the limiting block are provided with through holes that cooperate with the mounting rod. The through holes at both ends of the limiting block pass through the mounting rod and are located between the first annulus and the second annulus. The rotating arm is an L-shaped structure, with one end of the rotating arm fixedly connected to the limiting block and the other end rotatably connected to the positioning seat.

[0021] Technical effect: The above-mentioned configuration is adopted in this solution. The two ends of the U-shaped limiting block pass through the positioning column and are located between the two rings. Its two sides provide a shared and accurate axial positioning reference for the two rings, and also ensure the accuracy of the distance between them. Through the rotating arm design, the entire limiting block can be rotated open to make room for the support rod. The operation is extremely convenient and avoids interference.

[0022] Preferably, as an improvement, the positioning seat is provided with a U-shaped rotating seat, and the rotating arm is rotatably connected to the rotating seat through a pivot pin.

[0023] Technical effect: The above-mentioned settings in this solution facilitate the rotational connection between the limit block and the positioning seat. Attached Figure Description

Detailed Implementation

[0028] The following detailed description illustrates the specific implementation method: Example The basics are as follows: Figure 1-3 As shown: The front support component 1 of the motorcycle fuel tank includes a support rod 11 with both ends bent upwards and a first ring 12 and a second ring 13 disposed at both ends of the support rod 11. The support rod 11, the first ring 12 and the second ring 13 need to be combined and welded together before they can be used. The first ring 12 and the second ring 13 are respectively welded to both ends of the support rod 11.

[0029] The motorcycle fuel tank front support assembly fixture is used to position and restrict the movement of the support rod 11, the first ring 12, and the second ring 13, facilitating precise welding of these components. Figure 1As shown, the system includes a base plate 2, on which a positioning seat 3 and a support rod limiting member 7 are provided. The positioning seat 3 is used to support and position the support rod 11. There are two sets of support rod limiting members 7, which are arranged on both sides of the positioning seat 3. The two sets of support rod limiting members 7 abut against the upwardly bent part of the support rod 11 from the left and right sides, restricting the movement of the support rod 11. The base plate 2 is also provided with a positioning post 5 and a ring limiting member 6. The positioning post 5 is used to position the first ring 12 and the second ring 13. The positioning post 5 is horizontally arranged above the base plate 2 through the support seat 4. The first ring 12 and the second ring 13 are sequentially fitted onto the positioning post 5. The positioning post 5 positions the height of the first ring 12 and the second ring 13. The ring limiting member 6 is located between the first ring 12 and the second ring 13 and is rotatably connected to the positioning seat 3. The two sides of the ring limiting member 6 abut against the first ring 12 and the second ring 13, respectively.

[0030] like Figure 1 As shown, two positioning protrusions 31 are arranged side by side on the positioning base 3, and the positioning protrusions 31 are connected to the holes on the support rod 11. The top of the positioning protrusion 31 has a guide slope along the circumference, which serves as a guide to facilitate the passage of the holes on the support rod 11 through the positioning protrusions 31.

[0031] like Figure 2 As shown, the support rod limiting component 7 includes a limiting rod 71 and a fixing seat 72. The fixing seat 72 is fixedly connected to the base plate 2. The fixing seat 72 is provided with a contour groove for the limiting rod 71. The lower part of the limiting rod 71 is fixed in the contour groove by a pin 711. The upper part of the limiting rod 71 is bent towards the support rod 11. The end of the limiting rod 71 abuts against the upwardly bent part of the end of the support rod 11.

[0032] like Figure 3 As shown, the positioning post 5 includes a handle 51 and a mounting rod 52 arranged coaxially. The diameter of the handle 51 is larger than the diameter of the mounting rod 52. The mounting rod 52 passes through two support seats 4 arranged on the base plate 2 in sequence for fixing. The support seat 4 has a round hole, and a sleeve 41 that mates with the mounting rod 52 is provided in the round hole. The sleeve 41 is made of rubber, and the sleeve 41 and the mounting rod 52 are interference fit, so that the mounting rod 52 is not easy to move left or right or swing after installation.

[0033] like Figure 2 As shown, the circular limiting component 6 includes a limiting block 61 and a rotating arm 62. The limiting block 61 is a horizontally arranged U-shaped structure. Both ends of the U-shaped structure of the limiting block 61 are provided with through holes that cooperate with the mounting rod 52. The through holes at both ends of the limiting block 61 pass through the mounting rod 52 and are located between the first circular ring 12 and the second circular ring 13. The rotating arm 62 is an L-shaped structure. One end of the rotating arm 62 is fixedly connected to the limiting block 61, and the other end is rotatably connected to the positioning seat 3. The positioning seat 3 is provided with a U-shaped rotating seat 621, and the rotating arm 62 is rotatably connected to the rotating seat 621 through a shaft pin 622.

[0034] Before actual use, both the mounting column and the limiting rod 71 are installed on the floor, and the limiting block 61 is in a state of rotation towards the outside of the floor. When welding the front support 1, the support plate is placed on the positioning seat 3, and the hole on the support rod 11 needs to pass through the positioning protrusion 31 on the positioning seat 3 to achieve the positioning effect. Then, the lower part of the limiting rod 71 is placed in the contour groove of the fixing seat 72, and the pin 711 is inserted for fixation. At this time, the upper end of the limiting rod 71 abuts against the bent part of the end of the support rod 11. Figure 3 As shown, the mounting rod 52 of the positioning post 5 passes sequentially through the left support base 4 and the second ring 13. Then, the limiting block 61 is rotated upwards, causing the mounting rod 52 to pass through the through hole in the limiting block 61. The mounting rod 52 then continues to pass through the first ring 12 and the right support rod 11. Next, the first ring 12 is manually moved to the left to abut against the right side of the limiting block 61, and the second ring 13 is moved to the right to abut against the left side of the limiting block 61. At this point, the first ring 12 and the second ring 13 are in the welding position and are in contact with the welding points at both ends of the support rod 11. Finally, the first ring 12, the second ring 13, and the support rod 11 are mechanically welded together.

[0035] It is important to note that, such as Figure 3 As shown, the first ring 12 is welded from the right side, and the second ring 13 is welded from the left side. This avoids interference and obstruction of the view, and ensures that the first ring 12 always fits against the right side of the limiting block 61 and the second ring 13 always fits against the left side of the limiting block 61. This prevents the ring from moving due to welding force, which could lead to inaccurate welding positions.
