[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Please see Figure 1-4This utility model provides a technical solution: a movable workbench for welding electrical control cabinets, including a frame 1 and a workbench 4. A linear drive assembly 2 is fixedly installed on one side of the frame 1, and a slide 3 is fixedly installed on the other side of the frame 1. Connecting shafts 43 are welded and fixed on both sides of the workbench 4. One set of connecting shafts 43 is connected to a slider 44 through bearings, and the slider 44 is slidably connected to the slide 3. Another set of connecting shafts 43 is connected to a gear transmission box 5. The gear transmission box 5 is connected to a first motor 6. The first motor 6 is installed on the slide 25 of the linear drive assembly 2 by screws.

[0019] The first motor 6 operates via gear transmission box 5, driving the connecting shaft 43 on one side of the worktable 4 to rotate. The connecting shaft 43 drives the worktable 4 to move, causing the worktable 4 to rotate relative to the linear drive assembly 2 and the slide 3, thus adjusting the angle of the worktable 4. The angle of the worktable 4 is controlled by controlling the rotation direction and number of rotations of the output shaft of the first motor 6.

[0020] The linear drive assembly 2 can drive the worktable 4 to move along the linear direction of the carriage 3, and flexibly adjust the horizontal position of the worktable 4. When the workpiece to be welded is fixed on the worktable 4, the workpiece moves with the worktable 4, realizing flexible adjustment of the workpiece position and improving the flexibility of use.

[0021] The upper surface of the workbench 4 has multiple sets of negative pressure adsorption holes 41. The multiple sets of negative pressure adsorption holes 41 are evenly distributed, the adsorption force is evenly distributed, and the workpiece is not easily displaced.

[0022] The lower end face of the workbench 4 is provided with a vacuum hose 42, which is connected to the vacuum pump assembly.

[0023] The vacuum hose 42 is connected to multiple sets of negative pressure adsorption holes 41.

[0024] The worktable 4 can perform negative pressure adsorption and fixation on the workpiece. The essence of negative pressure adsorption is to reduce the air pressure between the adsorption surface and the workpiece, so that the external atmospheric pressure presses the workpiece tightly onto the worktable 4. The vacuum pump assembly works to extract the air in the adsorption area, so that multiple sets of negative pressure adsorption holes 41 form negative pressure. The external atmospheric pressure acts on the surface of the workpiece, and a pressure difference is formed with the negative pressure of the adsorption surface, thereby generating adsorption force to fix the workpiece. The worktable 4 performs adsorption without damage, avoiding scratches on the surface of the workpiece or internal stress deformation, and can adsorb irregular workpieces.

[0025] The gear transmission box 5 contains a first bevel gear 51 and a second bevel gear 52. The first bevel gear 51 and the second bevel gear 52 mesh and transmit power from one axis to another intersecting axis.

[0026] The output shaft of the first motor 6 is fixedly connected to the first bevel gear 51.

[0027] The worktable 4 is fixedly connected to the second bevel gear 52 via the connecting shaft 43 near the gear transmission box 5. The first motor 6 drives the first bevel gear 51 to rotate, the first bevel gear 51 drives the second bevel gear 52 to rotate, the second bevel gear 52 drives the connecting shaft 43 to rotate, and the connecting shaft 43 drives the worktable 4 to rotate relative to the linear drive assembly 2 and the slide 3, thereby adjusting the angle of the worktable 4.

[0028] The linear drive assembly 2 includes a U-shaped base 21, a second motor 22 is mounted on one end face of the U-shaped base 21, the output shaft of the second motor 22 is fixedly connected to the lead screw 23, and two sets of slide rods 24 are fixedly arranged on the U-shaped base 21, with the two sets of slide rods 24 located on both sides of the lead screw 23.

[0029] Both the slide rod 24 and the lead screw 23 pass through the slide table 25, and the slide table 25 and the slide rod 24 are slidably connected.

[0030] The working torque of the second motor 22 drives the lead screw 23 to rotate around the axis, which in turn drives the slide table 25 to slide along the slide rod 24. By controlling the rotation direction and number of rotations of the output shaft of the second motor 22, the horizontal position of the slide table 25 is adjusted. The slide table 25 drives the worktable 4 to move along the linear direction of the slide 3, thereby adjusting the horizontal position of the worktable 4.

[0031] Working Principle: During use, the workpiece is placed on the worktable 4, which uses negative pressure to fix the workpiece. The position of the worktable 4 is adjusted according to the actual usage requirements. The first motor 6 drives the worktable 4 to rotate relative to the linear drive assembly 2 and the slide 3 via the gear transmission box 5, thus adjusting the angle of the worktable 4. The angle of the worktable 4 is controlled by controlling the rotation direction and number of rotations of the output shaft of the first motor 6. The linear drive assembly 2 drives the worktable 4 to move along the linear direction of the slide 3, thus flexibly adjusting the horizontal position of the worktable 4. The horizontal position of the worktable 4 is controlled by controlling the rotation direction and number of rotations of the output shaft of the second motor 22. The workpiece follows the movement of the worktable 4, realizing flexible adjustment of the workpiece position.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
