[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors while simultaneously drying wastewater and removing it from the site. It has advantages such as being environmentally friendly, energy-saving, and highly efficient. Floor scrubbers are categorized into semi-automatic floor scrubbers, fully automatic floor scrubbers, walk-behind floor scrubbers, and ride-on floor scrubbers.

[0003] The patent publication number CN220993240U discloses a welding device, including an argon arc welding host and a welding gun fixedly connected to the surface of the argon arc welding host.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] Please see Figures 1-4 The floor scrubber steering wheel base welding equipment offers two technical solutions:

The positioning and clamping mechanism includes an adjustment component 4 and two left and right multi-positioning mechanisms. The floor scrubber steering wheel base 3 is composed of a main body plate of the weldment, two left and right driving wheel mounting plates, four reinforcing ribs, bushings and limiting pins.

The top of the adjusting plate 62 is rotatably connected to a first lead screw 67, and the surface of the pressure plate 66 is threadedly connected to the first lead screw 67.

[0026] The bearing sleeve positioning assembly 7 includes a fixed seat 71 fixed to the top of the C-shaped plate 5. Two first slide rods 72 are slidably connected to one side of the fixed seat 71. An arc plate 73 is fixedly connected to one end of each of the two first slide rods 72. A second lead screw 74 is threaded inside the fixed seat 71. The other end of the second lead screw 74 is rotatably connected to one side of the arc plate 73.

[0027] The positioning assembly 8 for the driving wheel mounting plate includes two second slide rails 81, one at the front and one at the rear. Both second slide rails 81 are fixedly connected to the top of the C-shaped plate 5. Both second slide rails 81 are slidably connected to sliders 82. A horizontal plate 83 is fixedly connected between the two sliders 82. A U-shaped block 84 is fixedly connected to one side of the horizontal plate 83. A third lead screw 85 is rotatably connected to the bottom of the C-shaped plate 5. The horizontal plate 83 and the third lead screw 85 are threadedly connected.

Two moving rods 92 are slidably connected to the surface of the third slide rail 91. Two second slide rods 93 are slidably connected to one side of the moving rods 92. A pressure block 94 is fixedly connected to one end of each of the two second slide rods 93. A fourth lead screw 95 is threaded inside the moving rod 92, and one end of the fourth lead screw 95 is rotatably connected to one side of the pressure block 94.

[0029] When welding the steering wheel base of the floor scrubber, multiple positioning components in the multi-positioning mechanism are used to connect the parts to be welded with the main plate, which facilitates subsequent welding operations, ensures the stability of the workpiece during welding, and improves the practicality of the device.

[0030] The second embodiment differs from the first embodiment in that: the adjustment component 4 includes a bidirectional threaded rod 41, which is rotatably connected to the left and right sides of the inner wall of the workbench 1. Moving blocks 42 are threaded onto both sides of the surface of the bidirectional threaded rod 41. Two support seats 43 are slidably connected to the top of the workbench 1. The tops of the two moving blocks 42 are fixedly connected to the bottoms of the two support seats 43 respectively. An adjustment motor 45 is fixedly connected to the right side of the workbench 1, and the output end of the adjustment motor 45 is fixedly connected to one end of the bidirectional threaded rod 41. A drive motor is fixedly connected to the left side of the left support seat 43, and the output end of the drive motor is fixedly connected to one side of the left C-shaped plate 5. The right C-shaped plate 5 is rotatably connected to the left side of the right support seat 43 via a rotating rod. An infrared sensor 44 is mounted on the left side and the inner side of the support seat 43 via a bracket. A controller 10 is mounted on the workbench 1, and the infrared sensor 44 is electrically connected to the controller 10.

[0031] Adjustment component 4 is used to adjust the distance between the two multi-positioning mechanisms, thereby clamping the steering wheel base of floor scrubbers of different sizes, improving the applicability of the device during use.

[0032] In use, place the main body plate of the floor scrubber steering wheel base between the two C-shaped plates 5. Start the adjusting motor 45 to rotate the bidirectional threaded rod 41. The rotation of the bidirectional threaded rod 41 drives the two support seats 43 to move closer together through the two moving blocks 42, thereby clamping the main body plate by the two C-shaped plates 5. During the movement of the support seats 43, the distance between the C-shaped plates 5 and the workpiece is detected by the infrared sensor 44. After clamping, the corresponding parts are connected in sequence by the limit pin positioning assembly 6, the bearing sleeve positioning assembly 7, the travel wheel mounting plate positioning assembly 8, and the reinforcing rib positioning assembly 9. When using the shaft pin positioning assembly 6, loosen the clamping sleeve 64 and adjust the position of the pressure plate 66 so that the pressure plate 66 is above the limiting shaft pin. Rotate the first lead screw 67 so that the pressure plate 66 presses against the top of the limiting shaft pin. When using the bearing sleeve positioning assembly 7, rotate the second lead screw 74 so that the two 75 clamp the bushing. When using the driving wheel mounting plate positioning assembly 8, rotate the third lead screw 85 so that the U-shaped block 84 abuts against the bottom of the driving wheel mounting plate. When using the reinforcing rib positioning assembly 9, rotate the fourth lead screw 95 so that the pressure block 94 contacts the reinforcing rib and presses the reinforcing rib against one side of the driving wheel mounting plate.
