Description

Technical Field

[0001] The present application relates to the technical field of motorcycle electrophoretic processing, and specifically discloses a tool for partial electrophoretic processing of a motorcycle frame. Background Art

[0002] After motorcycle parts are processed and formed, they need to be further electrophoretically coated. Electrophoretic coating is a coating method that cleverly utilizes the electrophoretic movement and segregation phenomenon of polymer electrolytes. By electrophoretically coating the surface of motorcycle parts, a uniform and firm paint film is formed on the surface of the body, effectively isolating the air and moisture, preventing the body from rusting, and effectively extending the service life of motorcycle parts.

[0003] In the existing processing of formed motorcycle frames, an assembly line mode is usually adopted. The motorcycle frames are lifted by a cableway conveying mechanism and a simple hook structure. The motorcycle frame assemblies are linearly lifted and fixed by the cableway conveying mechanism and transported according to the installed and laid out cableway conveying route. Then, according to the processing procedures of the motorcycle frames, the motorcycle frames are successively degreased, electrophoretically coated, sprayed and washed, and dried and baked to complete the production and processing of the motorcycle frames.

[0004] However, when electrophoretic coating is applied to a motorcycle frame, when the frame lifted by the hook passes through the electrophoretic coating tank for electrophoretic coating, since the electrophoretic coating tank contains a large amount of electrophoretic liquid, when the frame is immersed in the electrophoretic liquid, it is easily floated upward by the buoyancy of the liquid, causing the frame to detach from the hook and remain in the electrophoretic coating tank, making it impossible for the frame to proceed to the next processing step on the assembly line, thereby affecting the processing operation of the motorcycle frame and reducing the production efficiency of the motorcycle frame. Therefore, in view of this, the inventor provides a local electrophoretic processing tool for a motorcycle frame to solve the above-mentioned problem. Utility Model Content

[0005] The utility model aims to solve the problem that a conventional motorcycle frame is separated from a lifting hook and falls into the electrophoresis pool due to the buoyancy of the electrophoresis pool during electrophoresis, thus affecting the next processing and production of the frame.

[0006] In order to achieve the above-mentioned purpose, the basic scheme of the present invention provides a local electrophoretic processing tool for a motorcycle frame, including a fixed clamping claw detachably connected to a cableway, a lifting rod for lifting the motorcycle frame, and a buffer assembly arranged between the fixed clamping claw and the lifting rod and used to buffer the buoyancy of the electrophoretic liquid. The buffer assembly includes a fixed slide rod arranged at the bottom of the fixed clamping claw, a movable slide rod arranged at the top of the lifting rod, and a buffer spring arranged between the bottom of the fixed slide rod and the movable slide rod. The top of the movable slide rod is provided with a movable groove for accommodating the bottom end of the fixed slide rod. The movable slide rod is slidably connected to the outer side of the fixed slide rod through the movable groove. A middle limiting ring is provided at the inner middle part of the movable groove, and a top limiting ring is provided at the top port of the movable groove. The fixed slide rod is provided with a fixed limiting ring that can slide relatively on the inner wall of the movable groove. The bottom of the lifting rod is also provided with a closed-loop connecting rod lifting assembly for preventing the motorcycle frame from falling off.

[0007] The principles and effects of this basic solution are:

[0008] 1. Compared with the prior art, the present invention realizes the fixation, lifting and transportation of the motorcycle frame by sequentially arranging a fixed clamping claw, a buffer assembly, a lifting rod and a closed-loop connecting rod lifting assembly between the cableway conveying mechanism and the motorcycle frame, thereby facilitating the material transportation during the local electrophoresis processing of the motorcycle frame, thereby improving the production efficiency of the overall processing production line and the processing quality of the product. The closed-loop connecting rod lifting assembly and the buffer assembly respectively provide the motorcycle frame with double protection to prevent the frame from being forced out of the fixed clamping claw.

[0009] 2. Compared with the prior art, the present invention provides a movable slide bar that is slidably connected along the outer side of the fixed slide bar, and at the same time, the bottom of the fixed slide bar is relatively slidably connected along the inner wall of the movable groove, so that when the motorcycle frame is put into the electrophoretic paint film processing inside the electrophoretic pool and is subjected to the buoyancy of the electrophoretic liquid, the floating range of the motorcycle frame and the lifting rod is limited. By providing a buffer spring, structural protection is provided for the lifting rod that slides due to the buoyancy of the electrophoretic liquid. At the same time, the motorcycle frame is lifted using a closed loop, thereby preventing the motorcycle frame from being separated from the lifting rod, making the production and processing effect of the motorcycle frame better, and solving the problem that the traditional motorcycle frame is separated from the lifting hook and falls into the electrophoretic pool due to the buoyancy of the electrophoretic pool during electrophoresis, affecting the next step of the frame processing.

[0010] Furthermore, the fixed clamp adopts a cable grip structure. By providing the cable grip structure to clamp the fixed slide bar and the motorcycle frame to the cableway, the motorcycle frame can be produced and transported on an assembly line, making the entire processing process more coherent and greatly improving the production efficiency of the motorcycle frame.

[0011] Furthermore, the lifting rod is an open U-shaped structural rod connected in a horizontal manner. The lifting rod includes a first balancing crossbar provided at the bottom of the movable slide bar, a vertical connecting rod provided at one end of the first balancing crossbar, and a second balancing crossbar provided at the bottom end of the vertical connecting rod and arranged parallel to the first balancing crossbar. The closed-loop connecting rod lifting assembly is installed on the second balancing crossbar. The end of the second balancing crossbar away from the vertical connecting rod is detachably connected to an outer end limit block for preventing the motorcycle frame from falling off the lifting rod. By providing the first balancing crossbar and the second balancing crossbar, sufficient operating space is provided for the installation and connection between the motorcycle frame and the fixed clamp. By providing the U-shaped lifting rod, the structure is made more stable. By providing the outer end limit block, the range of movement of the motorcycle frame on the lifting rod is limited, thereby preventing the motorcycle frame from being separated from transportation.

[0012] Furthermore, an inner end stopper is provided at one end of the second balancing crossbar near the vertical connecting rod, which facilitates structural protection of the lifting rod and prevents the motorcycle frame from excessive movement during transportation, thereby causing collision and damage to the structure.

[0013] Furthermore, the closed-loop connecting rod lifting assembly includes a lifting adapter rod with one end that can be laterally mounted on the outside of the second balancing cross bar and is detachably rotatably connected to the second balancing cross bar, a lifting fixing rod laterally arranged at the bottom of the adapter rod, a first connecting rod hinged to one end of the lifting fixing rod, a second connecting rod hinged to the other end of the first connecting rod and used to hang the motorcycle frame, a third connecting rod hinged to the other end of the second connecting rod and detachably clamped to the other end of the lifting fixing rod, the second connecting rod and the lifting fixing rod are arranged opposite to each other, the first connecting rod and the third connecting rod are arranged opposite to each other, and both outer side surfaces of the second connecting rod are arcuate surfaces. By arranging the lifting fixing rod, the first connecting rod, the second connecting rod and the third connecting rod to form a closed loop connection, it is convenient to lock the lifting part structure of the motorcycle frame within the formed closed loop connecting rod structure, thereby locking the motorcycle frame during the lifting process and preventing the motorcycle frame from detaching from the lifting rod. By arranging the second connecting rod with an arcuate surface, it is convenient to provide structural protection when lifting the motorcycle frame. By arranging the third connecting rod to be detachably connected to the lifting fixing rod, it is convenient to adjust the closing and opening of the overall closed loop connecting rod structure.

[0014] Furthermore, the end of the hoisting and fixing rod away from the first connecting rod is provided with a snap-fit ​​seat, a side of which is provided with a snap-fit ​​groove, and the free end of the third connecting rod is provided with a snap-fit ​​block that is removably snap-fitted with the snap-fit ​​groove. The provision of the snap-fit ​​seat, snap-fit ​​block, and snap-fit ​​groove facilitates assembly and disassembly of the third connecting rod from the hoisting and fixing rod, thereby facilitating locking installation of the motorcycle frame.

[0021] like Figure 2 As shown, the buffer assembly includes a fixed slide bar 5 provided at the bottom of the fixed clamp 2, a movable slide bar 6 provided at the top of the lifting rod 4 and a buffer spring 7 provided between the bottom of the fixed slide bar 5 and the movable slide bar 6. A movable groove 8 is provided at the top of the movable slide bar 6 for accommodating the bottom end of the fixed slide bar 5. The movable slide bar 6 is slidably connected to the outer side of the fixed slide bar 5 through the movable groove 8. A middle limiting ring 9 is provided at the middle part of the inner side of the movable groove 8, and a top limiting ring is provided at the top port of the movable groove 8. The fixed slide bar 5 is provided with a fixed limiting ring 10 which can slide relatively on the inner wall of the movable groove 8. The bottom of the lifting rod 4 is also provided with a closed-loop connecting rod lifting assembly for preventing the motorcycle frame 3 from falling off.

[0022] Among them, such as Figure 1 As shown, the lifting rod 4 is an open U-shaped structural rod connected in a horizontal direction. The lifting rod 4 includes a first balancing cross bar 11 arranged at the bottom of the movable slide bar 6, a vertical connecting rod arranged at one end of the first balancing cross bar 11, and a second balancing cross bar 12 arranged at the bottom end of the vertical connecting rod and parallel to the first balancing cross bar 11. The closed-loop connecting rod lifting assembly is installed on the second balancing cross bar 12. The end of the second balancing cross bar 12 away from the vertical connecting rod is detachably connected to an outer end limit block 13 for preventing the motorcycle frame 3 from falling off the lifting rod 4, wherein the outer end limit block 13 is detachably connected to the end of the second balancing cross bar 12 by a thread.

[0023] Among them, such as Figure 2 As shown, an inner end limit block 14 is provided at one end of the second balancing cross bar 12 close to the vertical connecting bar.

[0024] Among them, such as Figure 2 As shown, the closed-loop connecting rod lifting assembly includes a lifting adapter rod 15 whose one end can be laterally mounted on the outside of the second balancing cross bar 12 and is detachably rotatably connected to the second balancing cross bar 12, a lifting fixing rod 16 laterally arranged at the bottom of the adapter rod, a first connecting rod 17 hinged to one end of the lifting fixing rod 16, a second connecting rod 18 hinged to the other end of the first connecting rod 17 and used to hang the motorcycle frame 3, and a third connecting rod 19 hinged to the other end of the second connecting rod 18 and detachably engaged with the other end of the lifting fixing rod 16. The second connecting rod 18 is arranged opposite to the lifting fixing rod 16, and the first connecting rod 17 and the third connecting rod 19 are arranged opposite to each other. Both outer side surfaces of the second connecting rod 18 are arcuate surfaces.

[0025] Among them, such as Figure 2 As shown, a clamping seat 20 is provided at one end of the lifting fixing rod 16 away from the first connecting rod 17 , a clamping groove 21 is provided on one side of the clamping seat 20 , and a clamping block 22 is provided at the free end of the third connecting rod 19 for detachable clamping with the clamping groove 21 .

[0026] During the specific implementation of the present invention, the hoisting adapter rod 15 and the closed-loop connecting rod hoisting assembly connected to its bottom need to be installed together with the second balancing crossbar 12. Simply insert the top of the hoisting adapter rod 15 onto the second balancing crossbar 12, then use the outer end limit block 13 to thread the second balancing crossbar 12 and tighten it, and place the hoisting adapter rod 15 between the outer end limit block 13 and the inner end limit block 14. Then, install the motorcycle frame 3 into the closed-loop connecting rod hoisting assembly. First, place the motorcycle frame 3 vertically on the ground, then pass the third connecting rod 19, the second connecting rod 18, and the first connecting rod 17 through any crossbar at the rear end of the motorcycle frame 3, and finally snap the clamping block 22 into the clamping groove 21. When the cableway 1 conveying mechanism transports the fixed clamp 2 and the entire motorcycle frame 3 to the electrophoretic pool, the motorcycle frame 3 will float up due to the buoyancy of the electrophoretic fluid. Since the structure of the fixed clamp 2 is fixed to the cableway 1 conveying mechanism, during the floating process of the motorcycle frame 3, the motorcycle frame 3 pushes the movable slide bar 6 on the lifting rod 4 to slide upward along the fixed slide bar 5, so that the buffer spring 7 is subjected to force, which plays a buffering role for the motorcycle frame 3, thereby reducing the floating distance of the motorcycle frame 3.

[0027] Compared with the prior art, the present invention provides a movable slide bar 6 that is slidably connected along the outer side of the fixed slide bar 5, and at the same time, relatively makes the bottom of the fixed slide bar 5 slidably connected along the inner wall of the movable groove 8, so that when the motorcycle frame 3 is put into the electrophoretic paint film processing inside the electrophoretic pool and is subjected to the buoyancy of the electrophoretic liquid, the floating range of the motorcycle frame 3 and the lifting rod 4 is limited. By providing a buffer spring 7, structural protection is provided for the lifting rod 4 that slides due to the buoyancy of the electrophoretic liquid. At the same time, the motorcycle frame 3 is lifted in a closed loop, thereby preventing the motorcycle frame 3 from being separated from the lifting rod 4, making the production and processing effect of the motorcycle frame 3 better, and solving the problem that the traditional motorcycle frame is separated from the lifting hook and falls into the electrophoretic pool due to the buoyancy of the electrophoretic pool during electrophoresis, affecting the next step of processing and production of the frame.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention.
