Description

Technical Field

[0001] This application relates to the technical field of auxiliary tooling for UV curing of motorcycle fuel tanks, and in particular to a universal fixture for UV curing of motorcycle fuel tanks. Background Technology

[0002] In the production process of motorcycle fuel tanks, UV curing is a crucial step. To ensure the stability and efficiency of the curing process, a dedicated curing production line is typically built. Within this line, fixtures are used to precisely fix the fuel tank in place, ensuring its position remains stable during UV curing and thus guaranteeing the quality of the curing process.

[0003] However, after motorcycle fuel tanks are manufactured, their inner walls have insertion slots that connect to blocks on fixtures for secure fastening. Because motorcycle fuel tanks come in many varieties, with differences in shape and structure between different models and specifications, the corresponding fixtures also vary considerably. In existing technology, fixtures are typically connected to production line supports using bolts. When production demands change and different types of fixtures are needed to accommodate new fuel tanks, workers must use additional tools to disassemble and reinstall the bolts. This cumbersome process not only prolongs fixture changeover time and reduces production changeover efficiency but also increases worker workload due to frequent tooling, negatively impacting the overall production line efficiency. Utility Model Content

[0004] In view of the above-mentioned prior art, in order to solve the problems of needing to use tools to remove bolts when replacing motorcycle fuel tank UV curing fixtures, which is cumbersome, inefficient and labor-intensive, this application provides a universal UV curing fixture for motorcycle fuel tanks.

[0005] This application provides a universal UV-curing fixture for motorcycle fuel tanks, which adopts the following technical solution: A universal fixture for UV curing motorcycle fuel tanks includes a bracket, a first base, and a fixing component. The first base is mounted on the bracket, and the fixing component is mounted on the first base. The fixing component includes a vertical rod, a horizontal rod, and a fixing member for fixing the motorcycle fuel tank. A first slot is provided on the first base. The bottom of the vertical rod is provided with a connector for engaging with the first slot. The horizontal rod is located at the top of the vertical rod, and the fixing member is located on the horizontal rod.

[0006] By adopting the above technical solution, the fixing component and the first base are detachably connected through the insertion and engagement of the connector and the first slot, replacing the traditional bolt fixing method. When it is necessary to replace the fixing component to adapt to different models of motorcycle fuel tanks, there is no need to use tools to remove the bolts. Simply pull the connector at the bottom of the vertical rod out of the first slot to complete the removal of the old fixing component. When installing the new fixing component, simply align the connector with the first slot and insert it. The operation is simple and quick, effectively shortening the fixture replacement time, improving production changeover efficiency, and reducing the labor intensity of workers caused by frequent tool use.

[0007] Preferably, the connector is a first connecting piece, which is arranged parallel to the first base, fixedly connected to the bottom of the vertical rod, and inserted into the slot.

[0008] By adopting the above technical solution, the first connecting piece is arranged parallel to the first base, increasing the contact area between the connector and the first slot, making the connection between the fixing component and the first base more stable. During the curing process of the motorcycle fuel tank, the fixing component is less likely to loosen or shift due to the weight of the fuel tank or slight external vibrations, ensuring the stability of the fuel tank fixation and thus guaranteeing the quality of UV curing.

[0009] Preferably, it further includes a second base and an auxiliary component. The second base is slidably mounted on the bracket, and the auxiliary component is mounted on the second base. The auxiliary component includes a connecting rod, a second connecting piece, and an abutment portion. The second connecting piece is disposed at the bottom of the connecting rod, and the abutment portion is disposed at the top of the connecting rod. The second base is mounted on the bracket and spaced apart from the first base. The second base has a second slot along its length direction, and a second opening is opened at one end of the second base. The second opening communicates with the second slot, and the second connecting piece is inserted into the second slot through the second opening.

[0010] By adopting the above technical solution, the sliding arrangement of the second base allows the distance between the auxiliary component and the fixed component to be adjusted according to the size of the motorcycle fuel tank, enhancing the versatility of the fixture. The auxiliary component is detachably connected via the insertion and engagement of the second connecting piece and the second slot. When the auxiliary component needs to be replaced to fit different fuel tanks, no tools are required; simply pull the second connecting piece out of the second slot to complete the replacement, further improving the fixture's replacement efficiency. The abutment part can provide auxiliary fixation from the other side of the fuel tank, forming a bidirectional fixation with the fixed component, effectively preventing the fuel tank from shaking or shifting during the curing process, thus improving the reliability of the fixation.

[0011] Preferably, the top surfaces of the first base and the second base are provided with clearance grooves along the length direction, and the clearance grooves are connected to the first slot and the second slot.

[0012] By adopting the above technical solution, when the bottom of the vertical rod of the fixing component is inserted into the first slot, the bottom of the vertical rod can be embedded in the clearance groove of the first base; when the bottom of the connecting rod of the auxiliary component is inserted into the second slot, the bottom of the connecting rod can be embedded in the clearance groove of the second base. The clearance groove plays a lateral limiting role for the vertical rod and the connecting rod, which can effectively prevent the vertical rod and the connecting rod from swaying or shifting left and right during use, ensuring the verticality and overall stability of the fixing component and the auxiliary component, avoiding misalignment of the oil tank due to component tilting, and ensuring the accuracy of UV curing.

[0013] Preferably, there are two second connecting pieces, which are arranged parallel to each other on the connecting rod. When the connecting rod is connected to the second base, the two second connecting pieces are located in the second slot and on the top surface of the second base, respectively.

[0014] By adopting the above technical solution, two parallel and spaced second connecting pieces form a "clamp"-like structure. The lower second connecting piece inserts into the second slot to connect with the second base, while the upper second connecting piece presses against the top surface of the second base, further enhancing the stability of the connection between the auxiliary component and the second base. This dual-limiting structure can effectively resist the reaction force generated when the abutting part abuts against the oil tank, preventing the auxiliary component from falling off or loosening from the second base, and ensuring the reliability of the auxiliary fixing effect.

[0015] Preferably, the fixing component is a plug-in block, and there are two plug-in blocks, which are respectively located at both ends of the crossbar, and the plug-in blocks cooperate with the plug-in slots on the motorcycle fuel tank.

[0016] By adopting the above technical solution, the two plug-in blocks respectively mate with the plug-in slots on the motorcycle fuel tank, fixing the fuel tank from both ends and making the force on the fuel tank more even. The mating method between the plug-in blocks and the plug-in slots provides precise positioning, enabling quick docking of the fuel tank with the fixing components and improving the efficiency of fuel tank installation. At the same time, this plug-in mating structure firmly fixes the fuel tank, making it less prone to relative displacement and ensuring the positional stability of the fuel tank during the UV curing process.

[0017] Preferably, the bracket includes a square steel tube and a round shaft. One end of the square steel tube is fixedly connected to the round shaft. The first base and the second base are disposed on the square steel tube. A connecting hole is provided along the length of the square steel tube. The connecting hole communicates with the interior of the square steel tube. A sliding block is slidably installed inside the square steel tube. A support is provided on the second base. The support is slidably installed in the connecting hole and connected to the sliding block.

[0018] By adopting the above technical solution, the square steel tube provides a stable mounting foundation for the first and second bases. Its rigid structure can withstand the weight of the fuel tank and fixture components, ensuring the overall structural stability of the fixture. The second base is connected to a sliding block inside the square steel tube via a support, and the support can slide along the connection hole, enabling the second base to slide smoothly along the length of the square steel tube. This facilitates adjustment of the distance between the auxiliary components and the fixed components to accommodate motorcycle fuel tanks of different sizes. The sliding block inside the square steel tube guides the sliding of the support, ensuring the accurate sliding direction of the second base and preventing deviation.

[0019] Preferably, an elastic element, which is a tension spring, is provided inside the square steel tube. One end of the tension spring is connected to the inner wall of the square steel tube, and the other end of the tension spring is connected to a sliding block.

[0020] By adopting the above technical solution and setting a tension spring, when the second base is pulled to adjust the spacing, the sliding block slides inside the square steel tube and stretches the tension spring, which stores elastic potential energy. After the second base is released, the tension spring pulls the sliding block back to its original position under the action of elastic restoring force, causing the second base to automatically approach the fixing component, so that the abutment part of the auxiliary component can tightly abut against the oil tank, realizing automated adjustment of auxiliary fixing. This structure eliminates the need for manual fixing of the second base, simplifying the operation process. At the same time, the continuous force of the tension spring ensures stable abutment force of the abutment part against the oil tank, further improving the reliability of oil tank fixing.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The fixing component and the first base are detachably connected via a connector that fits into the first slot, replacing the traditional bolt fixing method. When the fixing component needs to be replaced to fit different motorcycle fuel tank models, there is no need to use tools to remove the bolts; simply pull the connector at the bottom of the vertical rod out of the first slot to remove the old fixing component. When installing the new fixing component, simply align the connector with the first slot and insert it. The operation is simple and quick, effectively shortening the fixture changeover time, improving production changeover efficiency, and reducing the labor intensity of workers due to frequent tool use. 2. Two parallel, spaced-apart second connecting pieces form a "clamp"-like structure. The lower connecting piece inserts into the second slot to connect with the second base, while the upper connecting piece presses against the top surface of the second base, further enhancing the stability of the connection between the auxiliary component and the second base. This dual-limiting structure effectively resists the reaction force generated when the abutting part abuts against the oil tank, preventing the auxiliary component from falling off or loosening from the second base, ensuring the reliability of the auxiliary fixing effect. 3. By incorporating a tension spring, when the second base is pulled to adjust the spacing, the sliding block slides within the square steel tube, stretching the tension spring, which stores elastic potential energy. After the second base is released, the tension spring, under the action of elastic restoring force, pulls the sliding block back to its original position, causing the second base to automatically approach the fixing component. This ensures that the abutment part of the auxiliary component can tightly abut against the oil tank, achieving automated adjustment of the auxiliary fixing mechanism. This structure eliminates the need for manual fixing of the second base, simplifying the operation process. Simultaneously, the continuous force of the tension spring ensures stable abutment force against the oil tank, further improving the reliability of the oil tank fixing. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a universal fixture for UV curing motorcycle fuel tanks.

[0026] Reference Figure 1 and Figure 2A universal fixture for UV curing of motorcycle fuel tanks includes a bracket 1, a first base 2, a second base 3, a fixing component 4, and an auxiliary component 5. The first base 2 is fixedly mounted on the bracket 1, and the second base 3 is slidably mounted on the bracket 1 along the length of the bracket 1. The first base 2 and the second base 3 are spaced apart. The auxiliary component 5 is detachably mounted on the second base 3, and the fixing component 4 is detachably mounted on the first base 2.

[0027] Reference Figure 3 The fixing component 4 includes a vertical rod 41, a horizontal rod 42, and a fixing member 43 for fixing the motorcycle fuel tank. The first base 2 is parallel to the bracket 1. The first base 2 has a cavity. An opening is provided on the side wall of one end of the first base 2. The opening is connected to the cavity in the first base 2 and forms a first slot 21. The bottom of the vertical rod 41 is provided with a plug-in member 6 that mates with the first slot 21. The plug-in member 6 is a first connecting piece 61. The first connecting piece 61 is parallel to the first base 2 and is fixedly installed at the bottom of the vertical rod 41. The first connecting piece 61 is inserted into the first slot 21 through one side of the opening of the first base 2. The horizontal rod 42 is fixedly connected to the top of the vertical rod 41. The fixing member 43 consists of two plug-in blocks 431. The two plug-in blocks 431 are located at both ends of the horizontal rod 42 and mate with the plug-in slots on the motorcycle fuel tank.

[0028] A clearance groove 7 is provided on the top surface of the first base 2 along the length direction, and the clearance groove 7 is connected to the first slot 21. When the first connecting piece 61 is inserted into the first slot 21, the bottom of the vertical rod 41 will be embedded in the clearance groove 7. The shape and size of the clearance groove 7 can match the bottom contour of the vertical rod 41. When the vertical rod 41 is located in the clearance groove 7, the groove can form a lateral limit on the vertical rod 41 from the left and right sides, preventing the vertical rod 41 from swaying or shifting left and right during use, ensuring the verticality of the vertical rod 41 and the overall stability of the fixing component 4, and avoiding misalignment of the oil tank due to the tilt of the vertical rod 41.

[0029] Reference Figure 4The auxiliary component 5 includes a connecting rod 51, a second connecting piece 52, and an abutment part 53. The connecting rod 51 is vertically arranged above the second base 3. There are two second connecting pieces 52, which are spaced apart. One end of each connecting piece along its length is fixedly connected to the connecting rod 51. The second base 3 also has a cavity. An opening is provided on the side wall of the second base 3, which communicates with the cavity inside the second base 3 to form a second slot 31. When the connecting rod 51 is connected to the second base 3, the first connecting piece 52 located at the bottom of the connecting rod 51... Two connecting pieces 52 are inserted into the second slot 31 through one side of the opening of the second base 3; after the connection with the second base 3 is completed, the two second connecting pieces 52 are respectively located in the second slot 31 and on the top surface of the second base 3; the abutting part 53 is fixedly installed on the top of the connecting rod 51. The abutting part 53 includes a horizontal block 531 and two abutting blocks 532. The horizontal block 531 is fixedly installed on the top of the connecting rod 51, and the two abutting blocks 532 are respectively fixedly installed at both ends of the horizontal block 531. The two abutting blocks 532 are set towards the first base 2.

[0030] The second base 3 also has a clearance groove 7 along its length on its top surface, and the clearance groove 7 on the second base 3 is connected to the second slot 31. When the second connecting piece 52 is inserted into the second slot 31, the bottom of the connecting rod 51 will be embedded in the clearance groove 7.

[0031] When installing the fixture, firstly, the first base 2 is fixedly installed on the bracket 1 in a preset position. Then, the second base 3 is slidably installed on the bracket 1 along its length, keeping the first base 2 and the second base 3 spaced apart. Next, the first connecting piece 61 at the bottom of the vertical rod 41 is aligned with the opening on one side wall of the first base 2, keeping the first connecting piece 61 parallel to the first base 2. Then, the first connecting piece 61 is inserted into the cavity (first slot 21) of the first base 2 through the opening. During insertion, the end of the vertical rod 41 near the bottom is accurately embedded in the clearance groove 7 on the top surface of the first base 2. Utilizing the matching of the clearance groove 7 with the bottom contour of the vertical rod 41, the groove provides lateral restraint to the vertical rod 41 from both sides, ensuring the verticality of the vertical rod 41 and the overall stability of the fixing assembly 4. Then, the two spaced second connecting pieces 52 at the bottom of the connecting rod 51 are aligned with the opening on the side wall of the second base 3, and the second connecting pieces 52 are inserted into the cavity (second slot 31) of the second base 3 through the opening. After the connecting rod 51 is connected to the second base 3, the two second connecting pieces 52 are located in the second slot 31 and on the top surface of the second base 3, respectively, and the part of the connecting rod 51 located between the two second connecting pieces 52 is accurately embedded in the clearance groove 7, which enhances the stability of the auxiliary component 5 after installation.

[0032] Reference Figure 4 and Figure 5Specifically, a support 8 is fixedly installed on the bottom surface of the second base 3. The support 1 includes a round shaft 12 and a square steel pipe 11. The round shaft 12 and the square steel pipe 11 are fixedly connected. The end of the round shaft 12 away from the square steel pipe 11 is connected to an external rotating device. The first base 2 and the second base 3 are spaced apart on the square steel pipe 11. A connecting hole 111 is opened on the bottom surface of the square steel pipe 11 along the length direction. The connecting hole 111 communicates with the inside of the square steel pipe 11. The length of the connecting hole 111 is less than the length of the square steel pipe 11. The support 8 includes a first horizontal plate 81, a second horizontal plate 82, a first vertical plate 83 and a second vertical plate 84. The first horizontal plate 81 is located on the top surface of the square steel pipe 11 and is fixedly connected to the second base 3. The first vertical plate 83 is located on one side of the square steel pipe 11. One end of the first vertical plate 83 is fixedly connected to one end of the first horizontal plate 81. The second horizontal plate 82 is located on the bottom surface of the square steel pipe 11. One end of the second horizontal plate 82 is fixedly connected to the end of the first vertical plate 83 away from the first horizontal plate 81. The second vertical plate 84 is located in the connecting hole 111 on the bottom surface of the square steel pipe 11. One end of the second vertical plate 84 is fixedly connected to the second horizontal plate 82.

[0033] A sliding block 9 is provided inside the square steel tube 11. The sliding block 9 can slide along the length of the square steel tube 11. The end of the second vertical plate 84 away from the second horizontal plate 82 is fixedly connected to the sliding block 9. The end of the square steel tube 11 connected to the round shaft 12 is closed, and the end of the square steel tube 11 away from the round shaft 12 is open. The connecting hole 111 is located at the end of the square steel tube 11 near the open end. An elastic element 10 is provided inside the square steel tube 11. The elastic element 10 is a tension spring 101. One end of the tension spring 101 is fixedly connected to the closed end of the square steel tube 11, and the other end of the tension spring 101 is fixedly connected to one end of the sliding block 9.

[0034] Reference Figure 1 A fixing plate 13 is provided below the square steel pipe 11. The second horizontal plate 82 is located between the fixing plate 13 and the square steel pipe. A protrusion 14 is provided along the length of the bottom surface of the square steel pipe 11 away from the first vertical plate 83. One side of the fixing plate 13 is fixedly connected to the protrusion 14, and the fixing plate 13 does not abut against the square steel pipe 11. The second horizontal plate 82 slides between the fixing plate 13 and the square steel pipe 11.

[0035] When securing the motorcycle fuel tank, firstly, the fuel tank is precisely placed on the fixing component 4, ensuring that the insertion slot at the bottom of the fuel tank fully engages with the insertion blocks 431 at both ends of the crossbar 42. The engagement of the insertion blocks 431 with the insertion slot achieves initial fixation of one end of the fuel tank. At this time, the fixing component 4 is inserted into the first slot 21 of the first base 2 via the first connecting piece 61 at the bottom of the vertical rod 41, and the bottom of the vertical rod 41 is embedded in the clearance groove 7, ensuring the overall stability of the fixing component 4 without wobbling. Simultaneously, the operator pulls the support 8 of the second base 3 along the length of the square steel tube 11. The support 8 causes the connected sliding block 9 to slide within the square steel tube 11. At this time, the tension spring 101 within the square steel tube 11 is simultaneously stretched, storing elastic potential energy. During the pulling process, the second base 3 slides along the bracket 1, causing the upper auxiliary component 5 to move synchronously, gradually bringing the abutment part 53 at the top of the connecting rod 51 closer to the other end of the fuel tank. Next, the operator slowly releases the support 8. Under the action of elastic restoring force, the tension spring 101 gradually retracts, driving the sliding block 9 to move back to its initial position, and then pulling the second base 3 to slide in the opposite direction through the support 8. As the tension spring 101 continues to retract, the auxiliary component 5 moves closer to the oil tank. When the two abutting blocks 532 of the abutting part 53 are tightly attached to the outer wall of the other end of the oil tank and form a stable abutment, the retraction force of the tension spring 101 and the reaction force of the oil tank on the abutting part 53 reach a balance, and the support 8 no longer moves. At this time, the auxiliary component 5 cooperates with the second slot 31 of the second base 3 through the second connecting piece 52, and the bottom of the connecting rod 51 is embedded in the clearance groove 7, forming a bidirectional stable clamping of the oil tank together with the fixing component 4, ensuring that the oil tank is accurately and stably positioned during the UV curing process, and avoiding the impact of displacement on the curing quality.

[0036] The implementation principle of this application embodiment is as follows: First, the fixture as a whole uses the bracket 1 as the basic carrier. The first base 2 and the second base 3 respectively undertake the installation functions of the fixing component 4 and the auxiliary component 5, and the two are set at intervals to form a bidirectional fixing space. The fixing component 4 is connected to the first slot 21 of the first base 2 through the first connecting piece 61 at the bottom of the vertical rod 41, replacing the traditional bolt connection. With the avoidance groove 7 on the top surface of the first base 2, the vertical rod 41 is laterally limited, which not only ensures the stability of the installation of the fixing component 4, but also realizes quick disassembly and replacement without tools. The fixing component 4 can be adapted to the insertion slot structure of different oil tanks by replacing the plug-in block 431 of different specifications. Second, the auxiliary component 5 adopts a double second connecting piece 52 design. The bottom connecting piece is inserted into the second slot 31 of the second base 3, and the top connecting piece is pressed against the top surface of the base to enhance the installation stability. At the same time, the avoidance groove 7 on the top surface of the second base 3 further restricts the offset of the connecting rod 51. The second base 3 is connected to the sliding block 9 inside the square steel tube 11 via the support 8. It can slide along the connection hole 111 to adjust the distance to the fixing component 4, meeting the fixing requirements of oil tanks of different lengths. Finally, the tension spring 101 inside the square steel tube 11 enables automated adjustment of the auxiliary fixing: when the second base 3 is pulled, the sliding block 9 stretches the spring to store potential energy; after release, the spring's restoring force, through the sliding block 9 and the support 8, causes the second base 3 to automatically approach the oil tank, making the abutment block 532 of the abutment part 53 tightly fit against the outer wall of the oil tank, forming a bidirectional clamping with the insertion block 431 of the fixing component 4. This elastic adaptive structure eliminates the need for manual locking of the base position, simplifying the operation process and ensuring no displacement of the oil tank during UV curing through continuous and stable abutment force, thus guaranteeing curing quality.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
