Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A welding device for processing the bottom shell of a lawnmower includes a base 1 and a welding component 4 disposed above the base 1 for welding. The upper end of the base 1 is also provided with a clamping structure 6 for fixing the position of the bottom shell. A support 2 is provided on one side of the base 1, and a moving mechanism 3 is provided on one side of the support 2. A grinding component 5 is installed at the lower end of the moving mechanism 3. The welding component 4 is placed at the lower end of the moving mechanism 3, and the grinding component 5 is located on one side of the welding component 4. The grinding component 5 can be used to grind the weld seam of the bottom shell. A spraying structure 7 is installed at the upper end of the clamping structure 6 for spraying the weld seam of the bottom shell to protect the weld seam.

[0026] The moving mechanism 3 includes a fixed frame 31 fixedly installed on one side of the bracket 2 and a motor 32 set on one side of the fixed frame 31. The output end of the motor 32 is connected to a threaded rod 33, and the threaded rod 33 is placed inside the fixed frame 31. A threaded slider 34 is threadedly sleeved on the outer side of the threaded rod 33. A housing A35 is installed at the lower end of the threaded slider 34. A connecting frame 36 is set at the lower end of the housing A35. The welded part 4 and the grinding part 5 are respectively installed on the connecting frame 36. When the motor 32 is started, the threaded rod 33 can be driven to rotate. Under the drive of the threaded slider 34, the housing A35 and the connecting frame 36 can be moved.

[0027] The grinding component 5 includes an electric push rod B51 mounted on a connecting frame 36 and a housing B52 connected to the telescopic end of the electric push rod B51. Both the housing B52 and the housing A35 are equipped with micro motors. The lower end of the housing B52 is equipped with a grinding head 53 for grinding, and the grinding head 53 is connected to the output end of a set of micro motors. The top wall of the connecting frame 36 is connected to the output end of another set of micro motors. When the micro motors are started, the grinding head 53 can be driven to rotate, which can grind the weld seam of the bottom shell and effectively reduce the burrs and slag at the weld seam.

[0028] The clamping structure 6 includes a fixed frame 61 set on the upper end of the base 1 and a cylinder 62 set on the outside of the fixed frame 61. The telescopic end of the cylinder 62 is connected to a clamping plate 63. A guide rod 64 is also set on one side of the clamping plate 63. The guide rod 64 slides through the fixed frame 61. When the cylinder 62 is activated, it can push the clamping plate 63 to move and clamp the bottom shell. The guide rod 64 can slide within the fixed frame 61.

[0029] Two sets of clamping structures 6 are provided, and the two sets of clamping structures 6 are symmetrically distributed about the center line of the base 1, which can restrict the position of the bottom shell to be welded and facilitate welding processing.

[0030] The welding component 4 includes an electric push rod A41 mounted on the connecting frame 36 and a mounting base 42 connected to the telescopic end of the electric push rod A41. A welding head 43 for welding is mounted on the lower end of the mounting base 42. When the electric push rod A41 is started, the mounting base 42 and the welding head 43 can be moved so that the welding head 43 is close to the bottom shell where welding is to be performed, which facilitates welding.

[0031] In this embodiment: the bottom shell is placed on the base 1, and then fixed by the clamping structure 6, so that the bottom shell to be welded is positioned below the welding head 43. Then, the electric push rod A41 is activated, which pushes the mounting base 42 and the welding head 43 to move, so that the welding head 43 is close to the bottom shell to be welded. At the same time, the motor 32 is activated, which drives the threaded rod 33 to rotate. Under the action of the threaded slider 34, the machine housing A35 and the connecting frame 36 can be moved, so that the welding head 43 can move laterally. Welding can be completed using welding head 43. Once the weld has cooled to a temperature that is no longer hot to the touch, the micro motor inside the housing A35 is activated to drive the connecting frame 36 to rotate, thereby swapping the positions of the grinding part 5 and the welding part 4. Then, the electric push rod B51 is activated to push the housing B52 and the grinding head 53 downwards. After that, the micro motor is activated to drive the grinding head 53 to rotate, which can grind the weld seam of the bottom shell, effectively reducing burrs and slag at the weld seam, making the bottom shell weld seam more aesthetically pleasing and improving the strength of the weld seam.

[0032] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 5 The spraying structure 7 includes a housing 71 and a connecting conduit 72 disposed on one side of the housing 71. The housing 71 contains paint and a pump for drawing the paint is disposed inside the housing 71. One end of the pump is connected to the connecting conduit 72.

One end of the mounting bracket 74 is fixed to the housing 71. The mounting bracket 74 allows the connecting conduit 72 to be suspended above the base 1.

[0033] The housing 71 is fixed on a set of the fixing brackets 61, and the nozzle of the spray head 73 faces the weld of the bottom shell.

[0034] In this embodiment: After grinding, the pump is started to extract the paint from the housing 71 and export it through the connecting conduit 72. The paint is then discharged through the spray head 73, allowing it to be sprayed onto the bottom shell weld, thereby protecting the ground bottom shell weld and reducing damage.

[0035] Working principle: The bottom shell is placed on the base 1 and then fixed by the clamping structure 6, so that the bottom shell to be welded is positioned below the welding head 43. When the electric push rod A41 is activated, it can push the mounting base 42 and the welding head 43 to move, so that the welding head 43 is close to the bottom shell to be welded. At the same time, the motor 32 is activated, which drives the threaded rod 33 to rotate. Under the drive of the threaded slider 34, it can drive the machine box A35 and the connecting frame 36 to move, so that the welding head 43 can move laterally. Welding can be completed using the welding head 43. After the weld cools... Once the surface is no longer too hot to handle, the micro motor inside the housing A35 is activated, which drives the connecting frame 36 to rotate, causing the positions of the grinding part 5 and the welding part 4 to be interchanged. Then, the electric push rod B51 is activated, which pushes the housing B52 and the grinding head 53 downward. After that, the micro motor is activated, which drives the grinding head 53 to rotate, allowing the bottom shell weld to be ground. After grinding, the pump is activated, which extracts the paint from the housing 71 and discharges it through the connecting conduit 72, and then through the spray nozzle 73, so that the paint can be sprayed onto the bottom shell weld.
