Description

Technical Field

[0001] This invention relates to the field of motorcycle technology, and more particularly to a fuel tank assembly welding device. Background Technology

[0002] The motorcycle fuel tank is a critical component ensuring the normal operation of a motorcycle. Currently, welding motorcycle fuel tanks requires workers to use handheld welding torches, and the tanks are mostly manually clamped and secured. This process easily leads to welding instability, uneven welds, weak welds, and weld detachment, among other quality defects. These defects can result in insufficient tank strength, weld deformation, and low dimensional accuracy. More seriously, they can cause fuel leaks and accidents, severely impacting motorcycle safety. Summary of the Invention

[0003] The purpose of this invention is to provide a fuel tank assembly welding device, which is beneficial to improving the welding accuracy of motorcycle fuel tanks.

[0004] To achieve the above objectives, the present invention provides a combined welding seam device for fuel tanks; including a base plate, a seam welding machine is provided on the right rear side of the base plate, and auxiliary components; The auxiliary components include a grinder, a linear guide rail, a linear slider, a slide block, a multi-axis robot, a ball screw, and a servo motor. The grinder is located on the left rear side of the base plate. The linear guide rail is mounted on the base plate and symmetrically arranged, with the linear slider located on its top. The slide block is connected to the linear slider by bolts. The multi-axis robot is mounted on the slide block, and a pickup for holding an oil tank is mounted on its front head. The ball screw is rotatably connected to the base plate and detachably connected to the slide block, and is connected to the output shaft of the servo motor via a coupling. The servo motor is mounted on the right side of the base plate.

[0005] The seam welding machine is equipped with an upper electrode and a lower electrode.

[0006] The grinding machine has a grinding mechanism on the inner left side of the main shaft and a dust removal mechanism on the rear outer wall.

[0007] The upper electrode is driven to move vertically up and down by a driving mechanism. The driving mechanism includes a driving component and a guiding device. The driving component is installed on the top of the seam welding machine and its output end is connected to the insulating part of the upper electrode. The guiding device is located on the side of the upper electrode near the seam welding machine.

[0008] The grinding machine may also be equipped with cleaning equipment, drying equipment and leveling equipment in sequence on the side near the seam welding machine.

[0009] The oil tank assembly weld device further includes a detection component, which includes a mounting plate and a mating component. The mounting plate is installed on the top of the housing of the grinder, and the mating component is located on the front side of the mounting plate.

[0010] The mating components include a CCD camera and a limiting plate. The CCD camera is detachably connected to the mounting plate. The limiting plate is detachably connected to the mounting plate and abuts against the housing of the CCD camera.

[0011] This invention discloses a fuel tank assembly welding device. During processing, the fuel tank is clamped by a pick-up device on the head of a multi-axis robot. Then, the grinding angle of the fuel tank is adjusted by the self-adjusting structure of the multi-axis robot to grind and correct the fuel tank. Further, a burr-removing device set between the grinding machine and the seam welding machine is used for further trimming. Finally, a servo motor drives the ball screw to rotate, thereby moving the slide and driving the multi-axis robot to move the fuel tank onto the seam welding machine for automatic welding. This improves the quality and precision of the welding, prevents accidents caused by poor fuel tank welding quality, reduces the labor intensity of workers, and increases production efficiency, thus improving the welding precision of motorcycle fuel tanks.

It is understood that the aforementioned solution can reduce the labor intensity of workers, increase production efficiency, and improve the welding precision of motorcycle fuel tanks.

[0021] In this embodiment, a seam welding machine 102 is provided on the right rear side of the base plate 101. The base plate 101 can be fixed by anchor bolts. Furthermore, all standard parts used in this application can be purchased commercially, and can be customized according to the description and drawings. The specific connection methods for each part all employ conventional methods such as bolts, rivets, and welding, which are mature technologies in the prior art. The control method is automatic control via a controller. The controller's control circuit can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is primarily for protecting mechanical devices, the control method and circuit connections will not be explained in detail here.

[0022] Preferably, the grinding machine 103 is located on the left rear side of the base plate 101, the linear guide rail 104 is mounted on the base plate 101 and symmetrically arranged, and the linear slider 105 is provided on its top.

The ball screw 108 is rotatably connected to the base plate 101 and detachably connected to the slide block 106, and is connected to the output shaft of the servo motor 109 through a coupling. The servo motor 109 is mounted on the right side of the base plate 101. The grinding machine 103 is used to grind the welding position of the oil tank. The linear guide rail 104 is fixed by countersunk bolts and the linear slider 105 is set on the top. The base plate 101 is provided with rectangular protrusions to assist in limiting the linear guide rail 104. The rectangular protrusions are symmetrically arranged and do not interfere with the sliding of the linear slider 105. The slide block 106 is connected to the linear slider 105 by positioning pins and bolts. The multi-axis robot 107 directly adopts the existing technology of industrial robots. Its head picker (equivalent to a clamp, shown in full in the figure) is designed to fit oil tanks of different structural sizes. The two mounting ends of the ball screw 108 are respectively mounted on the detachable bearing seats on the base plate 101 through rotating bearings. The T-shaped mating nut of the ball screw 108 is fixed to the mounting end at the bottom of the slide block 106 by positioning pins and bolts, and its right end is connected to the output shaft of the servo motor 109 through a coupling. The servo motor 109 is fixed by bolts and has a brake mechanism and encoder (similar to the Z-axis ball screw motor of a vertical machining center) to facilitate stopping the shaft lock and position control.

[0023] Preferably, the seam welding machine 102 is provided with an upper electrode 110 and a lower electrode 111. The upper electrode 110 and the lower electrode 111 are used for welding.

[0024] Preferably, a grinding mechanism 112 is provided on the inner left spindle of the grinder 103, and a dust removal mechanism is provided on the rear outer wall. The grinding mechanism 112 adopts the existing grinding wheel grinding mechanism, and the grinding wheel is mounted on the electric spindle of the grinder 103. If a grinding wheel is not used during grinding or cooling is not required, a dust removal mechanism (not shown in the figure) can be directly set for dust removal. A conduit is installed on the rear wall of the grinder 103, and the outlet of the conduit is connected to a vacuum cleaner through a pipe (a horn cover is installed at the inlet of the conduit) to facilitate the adsorption of dust during grinding. If a cooling mechanism is set (set when the grinding allowance is large), then the dust removal mechanism is not set.

[0025] Preferably, the drive unit 113 is mounted on the top of the seam welding machine 102, and its output end is connected to the insulating part of the upper electrode 110; the guide device 114 is disposed on the side of the upper electrode 110 near the body of the seam welding machine 102. The drive unit 113 may be a servo electric cylinder, and the guide device 114 consists of a guide rod and a T-shaped linear sliding bearing mounted on the body of the seam welding machine 102, with the bottom of the guide rod connected to the insulating part of the upper electrode 110.

[0026] Preferably, a cleaning device, a drying device, and a leveling device can be sequentially arranged on the side of the grinding machine 103 near the seam welding machine 102 for coordination. By setting up the corresponding equipment, the device can realize assembly line production and processing. It should be noted that since the order or position of the equipment is different for different processing processes, the corresponding auxiliary equipment is not fully shown in the accompanying drawings of this application, but the processing can be completed directly using the corresponding CNC equipment in the prior art.

[0027] When using this invention to improve the welding precision and processing efficiency of motorcycle fuel tanks, the fuel tank is clamped by the pick-up device on the head of the multi-axis robot 107 during processing. Then, the grinding angle of the fuel tank is adjusted by the self-adjusting structure of the multi-axis robot 107 to grind and correct the fuel tank. Further, a burr trimming device (not shown in the figure, but existing sandbag grinding equipment can be used) is set between the grinding machine 103 and the seam welding machine 102 for trimming. Finally, the ball screw 108 is rotated by the servo motor 109 to move the slide 106, and then the multi-axis robot 107 moves the fuel tank onto the seam welding machine 102 for automatic welding. This improves the welding quality and precision, prevents accidents due to poor fuel tank welding quality, reduces the labor intensity of workers, and improves production efficiency, thereby improving the welding precision of motorcycle fuel tanks.

[0028] Second embodiment: like Figure 3 As shown, where Figure 3 This is a schematic diagram of the structure of a fuel tank assembly weld joint device. Based on the first embodiment, the present invention provides a fuel tank assembly weld joint device, which further includes a detection component. The detection component includes a mounting plate 201 and a mating component. The mating component includes a CCD camera 202 and a limiting plate 203.

[0029] Preferably, the mounting plate 201 is mounted on the top of the housing of the grinder 103; the mating component is disposed on the front side of the mounting plate 201. The mounting plate 201 is fixed by bolts, and a working indicator light that mates with the CCD camera 202 is provided on its outermost side. The mating component is used to detect whether the grinding position has been completely ground.

[0030] Preferably, the CCD camera 202 is detachably connected to the mounting plate 201; the limiting plate 203 is detachably connected to the mounting plate 201 and abuts against the housing of the CCD camera 202. The mounting plate 201 has a non-through T-shaped groove running from front to back, facilitating the installation of the T-shaped block on the housing of the CCD camera 202. The limiting plate 203 is fixed with bolts, facilitating the limiting of the CCD camera 202.

[0031] In this embodiment, after grinding the welding position of the oil tank, the product can be moved to the CCD camera 202 by the multi-axis robot 107. The CCD camera 202 takes a picture of the ground position and transmits the picture to the computer for comparison. If the ground position is under-processed or over-processed, the control system controls the working indicator light near the mounting plate 201 to flash red to provide an alarm, and the entire equipment will stop moving. After the worker removes the part, the equipment can be reset and restarted.

[0032] Third embodiment: like Figure 4 and Figure 5 As shown, where Figure 4 This is a diagram showing the installation location of the U-shaped frame. Figure 5 This is a schematic diagram of the structure of the spring locking component. Based on the second embodiment, the present invention provides a combined weld seam device for an oil tank. The combined weld seam device for an oil tank further includes a protective component, which includes a U-shaped frame 301, a rotating plate 302 and a spring locking component 303.

[0033] Preferably, the U-shaped frame 301 is mounted on the right side of the mounting plate 201; the rotating plate 302 is rotatably mounted on the U-shaped frame 301, and its bottom end is locked in place by the spring locking member 303. The U-shaped frame 301 is fixed by bolts, and an elastic rubber cable holder is installed inside to facilitate the cable connection of the CCD camera 202. The top of the rotating plate 302 is mounted on the support arm of the U-shaped frame 301 by a T-shaped pin, and the T-shaped pin is limited by a mounting nut. The spring locking component 303 consists of a rectangular plate, a detachable L-shaped plate connected to the rectangular plate, a U-shaped locking rod, and a spring. The lower front end of the rotating plate 302 is provided with an insertion hole to cooperate with the locking rod. Pulling the locking rod and compressing the spring will disengage the locking rod from the rotating plate 302. Then, the rotating plate 302 can be rotated to open the U-shaped frame 301. For subsequent locking, simply pull the locking rod first. When the rotating plate 302 rotates, the locking rod will be released, and the spring will release and push the locking rod into the rotating plate 302. Wear-resistant coatings are applied to the sliding surfaces of the locking rod and the rectangular and L-shaped plates, respectively. The wear-resistant coatings are metal-ceramic coatings, and by weight percentage, the metal-ceramic coating material consists of the following components: Ni-based alloy: 9-21%, Si-Al-CN amorphous particles: 75-91%. Subsequently, the metal-ceramic powder-coated locking rod is coated on the surface of the locking rod using appropriate coating equipment (the locking rod coated with metal-ceramic powder is placed in a workpiece box protected by a non-oxidizing atmosphere and moved towards a laser light source, where the laser light source melts and coats the metal-ceramic powder, forming a high wear-resistant metal-ceramic coating on the surface of the ordinary steel locking rod). The coating thickness is 2.1 mm.

[0034] In this embodiment, the U-shaped frame 301, the rotating plate 302, and the spring locking member 303 facilitate the setting of the working cable of the CCD camera 202.
