Description
Technical Field
[0001] This utility model relates to the field of motorcycle frame welding technology, specifically a motorcycle frame welding fixture. Background Technology
[0002] Motorcycles are a common mode of transportation with diverse uses. For transportation, their small size and light weight allow them to maneuver flexibly through narrow streets and congested areas, and parking is convenient, making them suitable for short-distance urban travel. They also have low purchase and maintenance costs, high fuel efficiency, and good economy. Furthermore, they are highly adaptable to complex road conditions such as rural dirt roads and unpaved mountain roads. For leisure and entertainment, motorcycles offer strong competitive and entertaining aspects, encompassing various forms such as road racing, and are favored by enthusiasts. Motorcycle touring allows for free route planning, enabling travelers to explore remote areas and experience the scenery and local customs along the way.
[0003] The "Motorcycle Frame Welding Fixture" disclosed in patent publication number "CN222095169U" addresses the aforementioned issues. It includes a support base with two support plates on top. A drive motor is located outside the support base, and a positive and negative lead screw is fixedly connected to the output end of the drive motor. Two transmission lead screw seats are threaded onto the outer surface of the positive and negative lead screws. The upper surfaces of the two transmission lead screw seats are fixedly connected to the bottom surfaces of the two support plates. Support blocks are fixedly connected to the upper surfaces of both support plates. Fixing seats are fixedly installed on the sides of the two support blocks that are far apart from each other. Electric push rods are fixedly installed on the sides of the two sets of fixing seats that are close to each other. The ends of the two sets of electric push rods that are close to each other pass through the support blocks and extend above the support plates. This motorcycle frame welding fixture has an automatic positioning and clamping structure for the motorcycle frame, ensuring stability during welding and improving welding speed.
[0004] The device in the aforementioned patent uses the power provided by the drive motor to move two transmission cable seats and two support plates, thereby facilitating the adjustment of the distance between the two support plates. It is suitable for positioning motorcycle frames of different sizes. If the frame is too long or too heavy, and the device cannot effectively provide auxiliary support and clamping structure, the frame is likely to sag due to the shift in the center of gravity, resulting in insufficient stability. It may even lead to serious consequences such as frame deformation and device damage.
[0005] To address these issues, this invention provides a motorcycle frame welding fixture. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a motorcycle frame welding fixture, which solves the aforementioned problems.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a motorcycle frame welding fixture, comprising a base, an adjustment mechanism below the base, and a clamping mechanism and a support mechanism above the base. The support mechanism includes a servo hydraulic cylinder and an outer frame. The bottom surface of the outer frame is fixedly mounted on the output end of the servo hydraulic cylinder. A third bidirectional screw is rotatably connected to the inner wall of one end of the outer frame. The other end of the third bidirectional screw is rotatably connected to the inner wall of the other end of the outer frame and penetrates the surface of the other end. A third servo motor is fixedly mounted on the other end of the third bidirectional screw. Support plates are screwed onto the third bidirectional screw. The top two sides of the support plates are slidably connected to the inner walls of the two sides of the outer frame.
[0008] By adopting the above technical solution, the outer frame installed at the output end is pushed up or down by a servo hydraulic cylinder. As the outer frame moves, the support plates screwed to the outside of the third bidirectional screw move in sync, thus resisting and supporting the frame that is too heavy or too long. At the same time, the rotation of the third bidirectional screw can achieve precise clamping of the frame, ensuring that the frame is stable and reliable during the positioning process. This solves the problem that if the frame is too long or too heavy, and the device cannot effectively provide auxiliary support and clamping structure, the frame is prone to sagging due to the shift of the center of gravity, resulting in insufficient stability, and may even cause serious consequences such as frame deformation and device damage.
[0009] Furthermore, the adjustment mechanism includes a stop block and a first bidirectional screw. One end of the first bidirectional screw is rotatably connected to the inner wall of one end of the stop block, and the other end of the first bidirectional screw is rotatably connected to the inner wall of the other end of the stop block and penetrates the surface of the other end. A first servo motor is fixedly installed on the other end of the first bidirectional screw, and a moving frame is screwed to the outer side of the first bidirectional screw.
[0010] Using the above technical solution, the first servo motor drives the first bidirectional screw installed at the output end to rotate stably. As the screw rotates, it drives the movable frames screwed to the outside to flexibly adjust the spacing. During this process, the movable frames can synchronously drive the clamping mechanism connected to them to achieve precise adjustment of the clamping spacing, thereby quickly adapting to workpieces of different sizes and efficiently completing the stable clamping task.
[0011] Furthermore, the base surface is provided with sliding grooves that penetrate the bottom surface, the top surface of the stop block of the adjustment mechanism is fixedly installed on the bottom surface of the base, and the bottom surface of the moving frame is slidably connected to the inside of the sliding groove.
[0012] By adopting the above technical solution, the base can effectively provide a stable and fixed position for the blocks installed on the bottom surface.
[0013] Furthermore, the clamping mechanism includes a second bidirectional screw and a second servo motor. The output end of the second servo motor is fixedly installed at one end of the second bidirectional screw. Movable covers are screwed onto the outer side of the second bidirectional screw. Servo electric actuators are fixedly installed on the bottom wall of the movable covers. Clamping plates are fixedly installed on the output ends of the servo electric actuators.
[0014] Using the above technical solution, the second bidirectional screw achieves precise spacing adjustment by driving the movable covers screwed to the outside. As the position of the movable covers is adjusted, the servo electric actuators installed on their bottom walls move synchronously. These servo electric actuators, with stable power output, drive the clamping plates installed at their output ends to move synchronously, which can firmly and accurately clamp the frames to be welded of different specifications, ensuring that the frames remain stable during the welding process and effectively improving the accuracy and efficiency of the welding operation.
[0015] Furthermore, one end of the second bidirectional screw of the clamping mechanism is rotatably connected to the inner wall of one end of the moving frame of the adjusting mechanism, and the other end of the second bidirectional screw is rotatably connected to the inner wall of the other end of the moving frame and penetrates the surface of the other end. The two sides of the clamping plate are slidably connected to the inner walls of the two sides of the moving frame, respectively.
[0016] Using the above technical solution, the movable frame can provide a stable sliding effect for the clamping plates that are slidably connected to the inner walls on both sides.
[0017] Furthermore, the bottom sides of the servo hydraulic cylinder of the support mechanism are respectively fixedly installed on the inner walls of the sliding groove on both sides.
[0018] By adopting the above technical solution, the sliding groove can effectively provide a stable fixed position for the servo hydraulic cylinders installed on the inner walls of both sides.
[0019] Beneficial effects
[0020] This utility model provides a welding fixture for motorcycle frames. Compared with the prior art, it has the following advantages:
[0021] 1. This motorcycle frame welding fixture, by adding a support mechanism, uses a servo hydraulic cylinder to push the outer frame installed at the output end to move up or down. As the outer frame moves, the support plates screwed to the outside of the third bidirectional screw move in sync, thus resisting and supporting the frame that is too heavy or too long. At the same time, the rotation of the third bidirectional screw can achieve precise clamping of the frame, ensuring that the frame is stable and reliable during positioning. This solves the problem that if the frame is too long or too heavy, and the device cannot effectively provide auxiliary support and clamping structure, the frame is prone to sagging due to the shift of the center of gravity, resulting in insufficient stability, and may even lead to serious consequences such as frame deformation and device damage.
[0022] 2. This motorcycle frame welding fixture, by adding a clamping mechanism, allows for precise spacing adjustment of the second bidirectional screw by driving the movable covers screwed to the outer sides. As the position of the movable covers is adjusted, the servo electric actuators installed on their bottom walls move synchronously. These servo electric actuators, with stable power output, drive the clamping plates installed at their output ends to move synchronously, which can firmly and accurately clamp the frames to be welded of different specifications, ensuring that the frame remains stable during the welding process and effectively improving the accuracy and efficiency of the welding operation.

[0030] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0031] Reference Figures 1 to 4 This application provides a motorcycle frame welding fixture, including a base 1, an adjustment mechanism 2 below the base 1, and a clamping mechanism 3 and a support mechanism 4 above the base 1. The support mechanism 4 includes a servo hydraulic cylinder 41 and an outer frame 42. The bottom surface of the outer frame 42 is fixedly installed on the output end of the servo hydraulic cylinder 41. A third bidirectional screw 44 is rotatably connected to the inner wall of one end of the outer frame 42. The other end of the third bidirectional screw 44 is rotatably connected to the inner wall of the other end of the outer frame 42 and penetrates the surface of the other end. A third servo motor 43 is fixedly installed on the other end of the third bidirectional screw 44. Each screw 44 is screwed with a support plate 45. The top two sides of the support plate 45 are slidably connected to the inner walls of the outer frame 42. The support mechanism 4 pushes the outer frame 42 installed at the output end to move up or down through the servo hydraulic cylinder 41. As the outer frame 42 moves, the support plates 45 installed on the outside of the third bidirectional screw 44 are driven to move in a synchronous manner, so as to resist and lift the frame that is too heavy or too long. At the same time, the rotation of the third bidirectional screw 44 can achieve precise clamping of the frame, ensuring that the frame is stable and reliable during the positioning process. The third bidirectional screw 44 is driven to rotate by the third servo motor 43.
[0032] Reference Figures 1 to 4In one aspect of this embodiment, the adjustment mechanism 2 includes a stop 21 and a first bidirectional screw 22. One end of the first bidirectional screw 22 is rotatably connected to the inner wall of one end of the stop 21, and the other end of the first bidirectional screw 22 is rotatably connected to the inner wall of the other end of the stop 21 and penetrates the surface of the other end. A first servo motor 23 is fixedly installed on the other end of the first bidirectional screw 22. Moving frames 24 are screwed to the outer side of the first bidirectional screw 22. The adjustment mechanism 2 drives the first bidirectional screw 22 installed at the output end to rotate stably through the first servo motor 23. As the screw rotates, the moving frames 24 screwed to the outer side are flexibly adjusted in spacing. During this process, the moving frames 24 can synchronously drive the clamping mechanism 3 connected to them to achieve precise adjustment of the clamping spacing, thereby quickly adapting to workpieces of different sizes and efficiently completing the stable clamping task.
[0033] The base 1 has sliding grooves 5 that penetrate the bottom surface. The top surfaces of the blocks 21 of the adjustment mechanism 2 are fixedly installed on the bottom surface of the base 1. The bottom surfaces of the moving frame 24 are slidably connected to the inner side of the sliding grooves 5. The base 1 can effectively provide a stable fixed position for the blocks 21 installed on the bottom surface.
[0034] Reference Figures 1 to 4 In one aspect of this embodiment, the clamping mechanism 3 includes a second bidirectional screw 31 and a second servo motor 32. The output end of the second servo motor 32 is fixedly installed at one end of the second bidirectional screw 31. Movable covers 33 are screwed onto the outer side of the second bidirectional screw 31. Servo electric actuators 34 are fixedly installed on the bottom wall of the movable covers 33. Clamping plates 35 are fixedly installed on the output ends of the servo electric actuators 34. The clamping mechanism 3 drives the second bidirectional screw 31 installed at the output end to rotate through the second servo motor 32. The rotating second bidirectional screw 31 drives the movable covers 33 screwed onto the outer side to achieve precise spacing adjustment. As the position of the movable covers 33 is adjusted, the servo electric actuators 34 installed on the bottom wall of the movable covers move synchronously. With stable power output, these servo electric actuators 34 drive the clamping plates 35 installed on the output ends to move synchronously, which can firmly and accurately clamp different specifications of the vehicle frame to be welded, ensuring that the vehicle frame remains stable during the welding process and effectively improving the accuracy and efficiency of the welding operation.
[0035] Reference Figures 1 to 4 In one aspect of this embodiment, one end of the second bidirectional screw 31 of the clamping mechanism 3 is rotatably connected to the inner wall of one end of the moving frame 24 of the adjusting mechanism 2, and the other end of the second bidirectional screw 31 is rotatably connected to the inner wall of the other end of the moving frame 24 and penetrates the surface of the other end. The two sides of the clamping plate 35 are slidably connected to the inner walls of the two sides of the moving frame 24 respectively. The moving frame 24 can provide a stable sliding effect for the clamping plate 35 that is slidably connected to the inner walls of the two sides respectively.
[0036] The servo hydraulic cylinder 41 of the support mechanism 4 is fixedly installed on the inner walls of the sliding groove 5 on both sides of its bottom. The sliding groove 5 can effectively provide a stable fixed position for the servo hydraulic cylinder 41 installed on the inner walls of both sides.
[0037] Working principle: The adjustment mechanism 2 drives the first bidirectional screw 22 installed at the output end to rotate stably through the first servo motor 23. As the screw rotates, the movable frame 24 screwed to the outside is flexibly adjusted in spacing. During this process, the movable frame 24 can synchronously drive the clamping mechanism 3 connected to it to achieve precise adjustment of the clamping spacing, thereby quickly adapting to workpieces of different sizes and efficiently completing the stable clamping task.
[0038] The base 1 has sliding grooves 5 that penetrate the bottom surface. The top surfaces of the blocks 21 of the adjustment mechanism 2 are fixedly installed on the bottom surface of the base 1. The bottom surfaces of the moving frame 24 are slidably connected to the inner side of the sliding grooves 5. The base 1 can effectively provide a stable fixed position for the blocks 21 installed on the bottom surface.
[0039] The clamping mechanism 3 drives the second bidirectional screw 31 installed at the output end to rotate via the second servo motor 32. The rotating second bidirectional screw 31 drives the movable covers 33 screwed to the outside to achieve precise spacing adjustment. As the position of the movable covers 33 is adjusted, the servo electric push rods 34 installed on their bottom walls move synchronously. With stable power output, these servo electric push rods 34 drive the clamping plates 35 installed at the output end to move synchronously, which can firmly and accurately clamp the frames to be welded of different specifications, ensuring that the frames remain stable during the welding process and effectively improving the accuracy and efficiency of the welding operation.
[0040] The movable frame 24 provides a stable sliding effect for the clamping plates 35 that are slidably connected to the inner walls on both sides. The top two sides of the support plate 45 are slidably connected to the inner walls on both sides of the outer frame 42. The support mechanism 4 pushes the outer frame 42 installed at the output end to move up or down through the servo hydraulic cylinder 41. As the outer frame 42 moves, the support plates 45 that are screwed to the outside of the third bidirectional screw 44 move in sync, so as to resist and lift the frame that is too heavy or too long. At the same time, the rotation of the third bidirectional screw 44 can achieve precise clamping of the frame, ensuring that the frame is stable and reliable during the positioning process. The third bidirectional screw 44 is driven to rotate by the third servo motor 43. The sliding groove 5 can effectively provide a stable fixed position for the servo hydraulic cylinders 41 installed on the inner walls on both sides.
