Description

Technical Field

[0001] This invention relates to the field of excavator welding technology, specifically to an excavator bucket welding device. Background Technology

[0002] Excavator bucket welding devices are specialized equipment used for welding components such as the excavator bucket body and bucket teeth. Their core function is to improve welding efficiency and weld quality by fixing the bucket's posture and precisely controlling welding parameters, thus meeting the high-strength and wear-resistant requirements of the bucket. However, existing excavator bucket welding devices have some shortcomings, such as: An excavator bucket welding device (application number CN202111309476.X) is described. This device, through its adjustability, can change the movement trajectory of the bucket, increasing its usability. It also improves dust collection by generating rotating airflow through a multi-stage rotating suction dust collection device. The adjustable welding device further increases the welding range. However, in actual use, this device struggles to position the workpiece or welding equipment, potentially leading to welding difficulties at designated locations or requiring positional adjustments that result in displacement when welding bucket workpieces.

[0003] Therefore, we propose an excavator bucket welding device to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide an excavator bucket welding device to solve the problem mentioned in the background art that current excavator bucket welding devices on the market have difficulty in positioning the workpiece or welding equipment, which may lead to the device being unable to weld at the specified position when welding the bucket workpiece.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a welding device for excavator buckets, comprising a workbench and a welding gun and a grinding wheel disposed on the top of the workbench, wherein the welding gun and the grinding wheel are processing devices with built-in batteries, and the welding gun and the grinding wheel are equipped with independent switches; A top plate is installed on the top of the workbench, and a hydraulic cylinder is installed inside the top plate. A pressure plate is installed at the bottom of the hydraulic cylinder. A sliding groove is connected to the bottom of the pressure plate, and a sliding ring is slidably connected to the bottom of the sliding groove. The sliding ring is fixedly connected to the welding gun and the grinding wheel inside. The bottom of the workbench is equipped with a drive mechanism that can drive the sliding ring to rotate. The top of the drive mechanism is connected to a dust collection mechanism. The pressure plate is fixedly connected to the dust collection mechanism. A fixed plate is installed on the top of the workbench, and the dust collection mechanism faces the fixed plate. The welding gun and the grinding wheel are located on the top of the fixed plate. The bottom of the fixed plate is equipped with an air outlet mechanism, and the drive mechanism is connected to the air outlet mechanism.

[0006] The drive mechanism rotates the sliding ring, which in turn drives the welding gun and grinding wheel to weld or grind the outer side of the workpiece. The height is adjusted by a hydraulic cylinder. During the grinding process, the drive mechanism also drives the dust collection and air exhaust mechanisms. The air exhaust mechanism blows air upwards to cool the workpiece and blows lighter impurities and debris to the top. The dust collection mechanism then collects the debris, thus preventing excessive debris from affecting the welding process.

[0007] As a preferred technical solution of the present invention, the workbench is fixedly connected to the drive mechanism, and the drive mechanism includes a drive motor, and a first sprocket is connected to the top of the drive motor. A chain is engaged on the outside of the first sprocket, and a second sprocket is connected to the other end of the chain. The top of the second sprocket is connected to the air outlet mechanism.

[0008] The above technical solution enables the drive mechanism to operate more stably when driving the dust collection mechanism, the air outlet mechanism and the sliding ring simultaneously, and makes it more convenient to process workpieces, thereby increasing the efficiency of the equipment during use.

[0009] As a preferred embodiment of the present invention, a grooved rod is connected to the top of the first sprocket, and a drive gear is slidably connected to the outside of the grooved rod. A bearing ring is rotatably connected to the top of the drive gear. The top of the bearing ring is fixedly connected to the pressure plate, and a toothed ring meshes with the outside of the drive gear. The bottom of the toothed ring is fixedly connected to the sliding ring. The diameter of the drive gear is much smaller than the diameter of the toothed ring.

[0010] The above technical solution enables the sliding engagement between the groove rod and the drive gear. When the pressure plate drives the welding gun and grinding wheel to rise and fall, the drive gear can still rotate synchronously with the groove rod. Furthermore, the bearing ring provides stable support for the drive gear, which can reduce radial sway during rotation. The meshing of the gear ring and the drive gear drives the sliding ring to rotate, thereby enabling the welding gun and grinding wheel to perform processing by rotating around the bucket in a circular motion.

[0011] As a preferred embodiment of the present invention, the bottom of the toothed ring is protected by a sliding ring, and the top of the convex rod is connected to a first bevel gear, and the right end of the first bevel gear meshes with a second bevel gear, the right end of the second bevel gear being connected to a dust collection mechanism.

[0012] The above technical solution enables the sliding ring to provide physical protection for the toothed ring, preventing welding spatter from adhering and causing meshing jamming; the vertical transmission between the first bevel gear and the second bevel gear directs the rotational power of the convex rod to the dust collection mechanism, reducing equipment energy consumption, while ensuring that the dust collection action is synchronized with welding and grinding, thus improving the efficiency of dust collection.

[0013] As a preferred technical solution of the present invention, the second bevel gear is fixedly connected to the top plate through a bearing seat, and the dust collection mechanism includes a turbine fan blade, and the left end of the turbine fan blade is fixedly connected to the second bevel gear. An air suction pipe is provided on the outside of the turbine fan blade, and a telescopic pipe is provided at the bottom of the air suction pipe. An air suction port is connected to the bottom of the telescopic pipe, and the outside of the air suction port is fixedly connected to the pressure plate.

[0014] The above technical solution enables the bearing housing to provide rigid support for the bevel gear set, ensuring stable power transmission; the rotation of the turbine fan blades generates negative pressure, which forms a directional dust collection channel through the suction pipe, telescopic pipe and suction port, which can quickly collect welding fumes; the telescopic pipe can extend and retract synchronously with the lifting and lowering of the pressure plate, ensuring that the suction port is always close to the welding area and preventing the spread of fumes.

[0015] As a preferred technical solution of the present invention, an exhaust valve is connected to the rear end of the suction pipe, and the exhaust valve is fixedly connected to the top plate. The bottom of the suction port is directly opposite the fixed plate. The top of the suction pipe is fixedly connected to the top plate. The suction pipe is connected to the suction port pipe through a telescopic pipe. When the hydraulic cylinder drives the pressure plate and the suction port to rise and fall, the telescopic pipe will extend and retract.

[0016] The above technical solution enables the exhaust valve to control the direction of smoke and dust emission, avoiding direct emission and environmental pollution; the design of the air intake facing the fixed plate ensures that the smoke and dust collection range accurately covers the welding area, thereby increasing the dust collection efficiency of the equipment when processing workpieces.

[0017] As a preferred embodiment of the present invention, a ventilation groove is installed on the inner side of the fixing plate, and a sliding rod is provided inside the fixing plate. A damper is provided on the outer side of the sliding rod, and a fixing pad is connected to the top of the damper. The fixing pad is slidably connected to the top of the pressure plate.

[0018] The above technical solution enables the fixing pad to fit tightly against the bucket surface under the elastic action of the damper, achieving flexible fixing of the bucket and avoiding bucket deformation caused by rigid clamping. The sliding rod provides guidance for the fixing pad, ensuring that it adapts to the bucket contour. The ventilation groove can work with the air outlet mechanism to form an airflow channel, accelerating heat dissipation in the welding area.

[0019] As a preferred technical solution of the present invention, the bottom of the fixed plate is attached to the air outlet mechanism, and the air outlet mechanism includes a guide fan blade, and the guide fan blade is fixedly connected to the top of the second sprocket. The guide fan blade is located inside the air inlet chamber, and the air inlet chamber is inside the workbench, and an air inlet valve is connected to the right end of the workbench.

[0020] The above technical solution enables the second sprocket to drive the guide fan blades to rotate, drawing in external cold air from the intake valve, and blowing it towards the welding area through the intake chamber, exhaust slot, and ventilation slot. This achieves active heat dissipation of the welding part, avoiding the degradation of welding material performance caused by high temperature. At the same time, the airflow can blow residual smoke and dust towards the intake port, helping to improve the dust removal effect.

[0021] As a preferred embodiment of the present invention, the air intake valve is fixedly connected to the workbench, and the top of the workbench is provided with an air outlet groove, which is located at the bottom of the ventilation groove. The top of the workbench is provided with a fixing rod, and the top of the workbench is fixedly connected to the top plate through the fixing rod.

[0022] The above technical solution enables the air outlet groove and the ventilation groove to be aligned vertically, ensuring that the airflow passes vertically through the fixed plate and reaches the welding area, thereby improving heat dissipation and auxiliary dust removal efficiency. In addition, the fixed rod rigidly connects the top plate and the workbench, enhancing the overall structural stability of the equipment.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: by driving the sliding ring to rotate through the drive mechanism, the sliding ring can drive the welding gun and grinding wheel to weld or grind the outer side of the workpiece. The height can be adjusted by the hydraulic cylinder. During the grinding process, the drive mechanism will also drive the dust collection mechanism and the air outlet mechanism to operate, so that the air outlet mechanism blows air upward to dissipate heat from the workpiece and blows lighter impurities and debris to the top. Then the dust collection mechanism will collect the debris, thereby avoiding the situation where excessive debris affects the welding process. Furthermore, the convex rod and drive gear are designed to allow for sliding contact between the convex rod and the drive gear. When the pressure plate drives the welding gun and grinding wheel to rise and fall, the drive gear can still rotate synchronously with the convex rod. The bearing ring provides stable support for the drive gear, which can reduce radial sway during rotation. The meshing of the gear ring and the drive gear drives the sliding ring to rotate, enabling the welding gun and grinding wheel to perform processing by rotating around the bucket in a circular motion. Furthermore, the dust collection mechanism ensures stable power transmission. The rotating turbine blades generate negative pressure, forming a directional dust collection channel through the suction pipe, telescopic pipe, and suction port, which can quickly collect welding fumes. The telescopic pipe can extend and retract synchronously with the pressure plate, ensuring that the suction port is always close to the welding area and preventing the spread of fumes.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Please see Figures 1-11 In order to solve the problem that the existing excavator bucket welding device is difficult to position the workpiece or welding equipment, which may lead to the device being unable to weld at the specified position when welding the bucket workpiece, the present invention provides a technical solution: an excavator bucket welding device, including a workbench 1 and a welding gun 8 and a grinding wheel 9 set on the top of the workbench 1, wherein the welding gun 8 and the grinding wheel 9 are processing devices with their own batteries, and the welding gun 8 and the grinding wheel 9 are equipped with independent switches; The top of the workbench 1 is equipped with a top plate 2, and a hydraulic cylinder 3 is provided inside the top plate 2. A pressure plate 4 is installed at the bottom of the hydraulic cylinder 3. A sliding groove 5 is connected to the bottom of the pressure plate 4, and a sliding ring 6 is slidably connected to the bottom of the sliding groove 5. The sliding ring 6 is fixedly connected to the welding gun 8 and the grinding wheel 9 inside. The bottom of the workbench 1 is equipped with a drive mechanism, which can drive the sliding ring 6 to rotate. The top of the drive mechanism is connected to a dust collection mechanism. The pressure plate 4 is fixedly connected to the dust collection mechanism. The top of the workbench 1 is equipped with a fixed plate 10, and the dust collection mechanism is directly opposite the fixed plate 10. The welding gun 8 and the grinding wheel 9 are located on the top of the fixed plate 10. The bottom of the fixed plate 10 is equipped with an air outlet mechanism, and the drive mechanism is connected to the air outlet mechanism. The bucket workpiece is placed on top of the fixed plate 10, thereby fixing the workpiece. Then, the drive mechanism is activated, causing the sliding ring 6 to rotate. This causes the sliding ring 6 to rotate the welding gun 8 and the grinding wheel 9. Subsequently, the hydraulic cylinder 3 drives the sliding ring 6 to rise and fall through the pressure plate 4 and the slide groove 5, thereby adjusting the position of the welding gun 8 and the grinding wheel 9. At the same time, the drive mechanism also drives the dust collection mechanism and the air exhaust mechanism to operate. During the welding process, the bucket workpiece is cooled by the air exhaust mechanism, and the dust collection mechanism sucks in the debris to prevent it from affecting the welding work. The excavator bucket workpiece to be welded is placed on the fixed plate 10 on the top of the workbench 1. The workpiece's gravity presses down on the fixed pad 14, causing the damper 12 inside the fixed plate 10 to elastically contract along the sliding rod 13. The workpiece is flexibly fixed by the adaptive deformation of the fixed pad 14, which tightly fits the surface of the bucket, thus avoiding deformation of the bucket caused by rigid clamping. The bottom of the workpiece is aligned with the ventilation groove 11 of the fixed plate 10. Then, the pressure plate 4 is driven to rise and fall by the hydraulic cylinder 3 inside the top plate 2, which drives the bottom sliding groove 5, sliding ring 6, welding gun 8 and grinding wheel 9 to adjust their height synchronously, so that the welding gun 8 and grinding wheel 9 move around the workpiece in a circle. The workbench 1 is fixedly connected to the drive mechanism, and the drive mechanism includes a drive motor 15. The top of the drive motor 15 is connected to a first sprocket 16. A chain 17 is engaged on the outside of the first sprocket 16. The other end of the chain 17 is connected to a second sprocket 18. The top of the second sprocket 18 is connected to the air outlet mechanism. The top of the first sprocket 16 is connected to a grooved rod 19, and a drive gear 20 is slidably connected to the outside of the grooved rod 19. A bearing ring 21 is rotatably connected to the top of the drive gear 20. The top of the bearing ring 21 is fixedly connected to the pressure plate 4. A toothed ring 7 meshes with the outside of the drive gear 20, and the bottom of the toothed ring 7 is fixedly connected to the sliding ring 6. The diameter of the drive gear 20 is much smaller than the diameter of the toothed ring 7. The bottom of the toothed ring 7 is protected by the sliding ring 6, and the top of the convex rod 19 is connected to the first bevel gear 22, and the right end of the first bevel gear 22 is engaged with the second bevel gear 23, and the right end of the second bevel gear 23 is connected to the vacuuming mechanism. The second bevel gear 23 is fixedly connected to the top plate 2 via a bearing seat, and the dust collection mechanism includes a turbine fan blade 24. The left end of the turbine fan blade 24 is fixedly connected to the second bevel gear 23. An air suction pipe 25 is provided on the outside of the turbine fan blade 24, and a telescopic pipe 26 is provided at the bottom of the air suction pipe 25. An air suction port 27 is connected to the bottom of the telescopic pipe 26. The outside of the air suction port 27 is fixedly connected to the pressure plate 4. The rear end of the suction pipe 25 is connected to the exhaust valve 28, and the exhaust valve 28 is fixedly connected to the top plate 2. The bottom of the suction port 27 is directly opposite the fixed plate 10. The top of the suction pipe 25 is fixedly connected to the top plate 2. The suction pipe 25 is connected to the suction port 27 through the telescopic pipe 26. When the hydraulic cylinder 3 drives the pressure plate 4 and the suction port 27 to rise and fall, the telescopic pipe 26 will extend and retract. A ventilation groove 11 is installed on the inner side of the fixed plate 10, and a sliding rod 13 is provided inside the fixed plate 10. A damper 12 is provided on the outer side of the sliding rod 13. A fixing pad 14 is connected to the top of the damper 12, and the fixing pad 14 is slidably connected to the top of the pressure plate 4. The bottom of the fixed plate 10 is attached to the air outlet mechanism, and the air outlet mechanism includes a guide fan blade 29. The guide fan blade 29 is fixedly connected to the top of the second sprocket 18. The guide fan blade 29 is located inside the air inlet chamber 32, and the air inlet chamber 32 is inside the workbench 1. An air inlet valve 31 is connected to the right end of the workbench 1. The air intake valve 31 is fixedly connected to the workbench 1, and the top of the workbench 1 is provided with an air outlet groove 30, which is located at the bottom of the ventilation groove 11. The top of the workbench 1 is provided with a fixing rod 33, and the top of the workbench 1 is fixedly connected to the top plate 2 through the fixing rod 33. When the drive mechanism is running, it also drives the dust collection mechanism, which causes the convex rod 19 to drive the first bevel gear 22 to rotate, which in turn drives the second bevel gear 23 and the turbine fan blade 24 to rotate. The turbine fan blade 24 rotates inside the suction pipe 25, which causes the suction port 27 to absorb the debris on the top of the fixed plate 10 into the suction pipe 25 and discharge it through the exhaust valve 28. At the same time, the second sprocket 18 drives the guide fan blade 29 to rotate, which causes the guide fan blade 29 to discharge the gas inside the air intake chamber 32 through the air outlet groove 30, thereby cooling the workpiece on the top of the fixed plate 10. When the workpiece is fixed, the damper 12 will drive the fixing pad 14 to move, so that the fixing plate 10 fixes the workpiece through the fixing pad 14. After processing is completed, the drive motor 15 is turned off, so that the welding gun 8 and the grinding wheel 9 are shut off, and the hydraulic cylinder 3 drives the pressure plate 4 to rise back to the initial position. After the workpiece is removed, the cleaning door at the bottom of the worktable 1 is opened to remove the small amount of residual debris in the air inlet chamber 32, completing one complete processing cycle.

[0028] Working principle: When using the excavator bucket welding device, first connect the device to an external power source. Then place the bucket workpiece on top of the fixed plate 10, which fixes the workpiece. Then, the drive mechanism is activated, causing the sliding ring 6 to rotate. This causes the welding gun 8 and the grinding wheel 9 to rotate. Subsequently, the hydraulic cylinder 3 moves the sliding ring 6 up and down through the pressure plate 4 and the slide groove 5, thereby adjusting the position of the welding gun 8 and the grinding wheel 9. At the same time, the drive mechanism also drives the dust collection mechanism and the air exhaust mechanism. During the welding process, the bucket workpiece is cooled by the air exhaust mechanism, and the dust collection mechanism sucks in debris to prevent it from affecting the welding work. The excavator bucket workpiece to be welded is placed on the fixed plate 10 on the top of the workbench 1. The workpiece's gravity presses down on the fixed pad 14, causing the damper 12 inside the fixed plate 10 to elastically contract along the sliding rod 13. The workpiece is flexibly fixed by the adaptive deformation of the fixed pad 14, which tightly fits the surface of the bucket, thus avoiding deformation of the bucket caused by rigid clamping. The bottom of the workpiece is aligned with the ventilation groove 11 of the fixed plate 10. Then, the pressure plate 4 is driven to rise and fall by the hydraulic cylinder 3 inside the top plate 2, which drives the bottom sliding groove 5, sliding ring 6, welding gun 8 and grinding wheel 9 to adjust their height synchronously, so that the welding gun 8 and grinding wheel 9 move around the workpiece in a circle. When the drive mechanism is running, the drive motor 15 will also drive the first sprocket 16 to rotate, which in turn drives the second sprocket 18 to rotate via the chain 17. This causes the first sprocket 16 to drive the grooved rod 19 to rotate, which in turn drives the drive gear 20 to rotate. The drive gear 20 will also drive the gear ring 7 to rotate, which in turn drives the sliding ring 6 to rotate. This causes the sliding ring 6 to drive the welding gun 8 and the grinding wheel 9 to adjust their positions. The hydraulic cylinder 3 will also drive the pressure plate 4, the slide groove 5, and the sliding ring 6 to rise and fall. When the drive mechanism is running, it also drives the dust collection mechanism, which causes the convex rod 19 to drive the first bevel gear 22 to rotate, which in turn drives the second bevel gear 23 and the turbine fan blade 24 to rotate. The turbine fan blade 24 rotates inside the suction pipe 25, which causes the suction port 27 to absorb the debris on the top of the fixed plate 10 into the suction pipe 25 and discharge it through the exhaust valve 28. At the same time, the second sprocket 18 drives the guide fan blade 29 to rotate, which causes the guide fan blade 29 to discharge the gas inside the air intake chamber 32 through the air outlet groove 30, thereby cooling the workpiece on the top of the fixed plate 10. The first bevel gear 22 at the top of the grooved rod 19 rotates synchronously and meshes with the second bevel gear 23, which drives the turbine fan blade 24 to rotate in the intake pipe 25 to generate negative pressure. The negative pressure is transmitted to the intake port 27 through the telescopic pipe 26. The intake port is directly facing the workpiece on the fixed plate 10, which can quickly collect welding fumes and debris. Impurities are discharged from the exhaust valve 28 through the intake pipe 25. Since the diameter of the drive gear 20 is much smaller than the diameter of the toothed ring 7, when the grooved rod 19 drives the drive gear 20 to rotate at high speed, the toothed ring 7 will only rotate slowly. As a result, when the drive motor 15 drives the turbine fan blade 24 and the guide fan blade 29 to rotate at high speed, the toothed ring 7 will only drive the sliding ring 6, the welding gun 8 and the grinding wheel 9 to rotate slowly to adjust their positions, thereby increasing the efficiency of the device in heat dissipation. When the workpiece is fixed, the damper 12 will drive the fixing pad 14 to move, so that the fixing plate 10 fixes the workpiece through the fixing pad 14. After the processing is completed, the drive motor 15 is turned off, so that the welding gun 8 and the grinding wheel 9 are turned off. The hydraulic cylinder 3 drives the pressure plate 4 to rise back to the initial position. After the workpiece is taken out, the cleaning door at the bottom of the worktable 1 is opened to remove the small amount of residual debris in the air inlet chamber 32, thus completing a complete processing flow. By using the toothed ring 7 and the sliding ring 6 to drive the welding gun 8 and the grinding wheel 9 for position adjustment, the fixed plate 10 does not need to move the top bucket workpiece for positioning or position adjustment. This prevents the semi-circular bucket workpiece from moving during processing, thus increasing the efficiency of the equipment in welding bucket workpieces.
