[0040] Welding technology is widely used in mechanical processing and is also an indispensable technology. Therefore, the welding workbench has become an indispensable equipment in mechanical production and processing. The welding workbench currently used is relatively simple, with only a fixed platform. When welding large castings, it is necessary to move and adjust the parts or the operator needs to constantly rotate around the welding flat workbench to operate, which is a large workload and low welding efficiency.

[0041] To solve the above problems, Figure 1As shown, this embodiment provides a welding workbench. The welding workbench includes a platform assembly 1, a rotation drive assembly, a lifting drive assembly and a base 2. The platform assembly 1 includes a first platform 11 and a second platform 12 stacked together, the first platform 11 is located above the second platform 12, and the second platform 12 is provided with an avoidance hole; the output shaft of the rotation drive assembly passes through the avoidance hole and is connected to the second platform 12, and the rotation drive assembly is configured to drive the first platform 11 to rotate; the output end of the lifting drive assembly is connected to the first platform 11, and the lifting drive assembly is configured to drive the second platform 12 to move in a vertical direction; the platform assembly 1, the rotation drive assembly and the lifting drive assembly are all arranged on the base 2, and a plurality of moving wheels 3 are arranged at the bottom end of the base 2.

[0042] The workpiece to be welded is placed on the first platform 11, and the lifting drive assembly works to move the second platform 12 in the vertical direction. Since the first platform 11 is stacked on the second working platform, the first platform 11 also moves in the vertical direction with the second platform 12 to adjust to a suitable height for welding operations. When the angle of the workpiece to be welded needs to be adjusted during the welding process, the rotating drive assembly works to rotate the first platform 11, thereby changing the angle of the workpiece to be welded. During the welding process, the platform assembly 1 can be adjusted to a suitable height according to the height of the operator, which is convenient for welding operations. When the angle of the workpiece to be welded needs to be adjusted, there is no need to move the workpiece to be welded itself, and there is no need for the operator to move, which reduces the workload and improves work efficiency. A number of moving wheels 3 are provided at the bottom end of the base 2. The moving wheels 3 enable this welding work platform to be easily moved between different areas without spending a lot of time and manpower to carry. When the welding workbench needs to be maintained or repaired, the moving wheels 3 enable the welding workbench to be easily moved to the maintenance area, which is convenient for inspection and maintenance work.

[0043] Specifically, the rotation drive assembly includes a first mounting frame and a first driving member, the first mounting frame is arranged at the bottom of the second platform 12, the first driving member is arranged on the first mounting frame, and the output shaft of the first driving member is connected to the first platform 11 through the avoidance hole. The first driving member can be installed at the bottom of the second platform 12 by the first mounting frame, and the output shaft of the first driving member is connected to the first platform 11 by passing the output shaft of the first driving member through the avoidance hole, so that the output shaft of the first driving member can drive the first platform 11 to rotate when it rotates around its own axis. Among them, the first driving member can be a rotary motor, a servo motor, a stepping motor, etc., or a gear transmission device or a rack transmission device, etc. In the prior art, any structure that can realize driving the first platform 11 to rotate can be used as the first driving member in this embodiment, and this embodiment does not limit this.

[0044] In this embodiment, the first driving member is electrically connected to the external power supply through the first control switch 4. When the first control switch 4 is closed, the first driving member is started, driving the first platform 11 to rotate, so that the angle of the workpiece to be welded placed on the first platform 11 can be adjusted. When the first platform 11 rotates to a suitable position, the control switch is disconnected, so that the first driving member stops working. The first control switch 4 in this embodiment is a common control switch structure in the prior art, and the specific control principle is not described in detail here.

[0045] Specifically, the lifting drive assembly includes a second mounting frame and a second driving member, the second mounting frame is arranged on the base 2, the second driving member is arranged on the second mounting frame, and the output shaft of the second driving member is connected to the second platform 12. The second driving member can be mounted on the base 2 through the second mounting frame, and the output shaft of the second driving member is connected to the second platform 12, so that the output shaft of the second driving member can drive the second platform 12 to move when it moves in the vertical direction.

[0046] In this embodiment, the second driving member is a one-way oil cylinder. When it is necessary to drive the second platform 12 to rise, the hydraulic pump supplies oil to the oil cylinder, and the oil enters the inside of the oil cylinder from the oil inlet of the one-way valve. At this time, the piston moves upward under the action of the hydraulic pressure to drive the second platform 12 to rise; when it rises to a suitable height, the hydraulic pump stops supplying oil to the oil cylinder. Due to the action of the one-way valve, the oil is trapped in the oil cylinder, and the piston stops moving, so that the second platform 12 remains at this suitable height; when it is necessary to drive the second platform 12 to descend, the pressure relief port of the one-way valve is opened to allow the oil to flow out of the oil cylinder, and the second platform 12 will slowly descend under the action of its own weight, while driving the piston to move downward.

[0047] It should be noted that, in other embodiments, the second driving member may also be a linear motor. In the prior art, any structure that can drive the second platform 12 to rise and fall can be used as the second driving member in this embodiment, and this embodiment does not limit this.

[0048] Preferably, the second driving member is electrically connected to the external power supply through the second control switch 5. When the second control switch 5 is closed, the second driving member is started, driving the second platform 12 to rise, so that the angle of the workpiece to be welded placed on the second platform 12 can be adjusted. When the second platform 12 rises to a suitable position, the control switch is disconnected, so that the second driving member stops working, and the second platform 12 remains in this position. The second control switch 5 in this embodiment is a common control switch structure in the prior art, and the specific control principle is not described in detail here.

[0049] Specifically, Figure 1As shown, the base 2 is recessed with an escape space 21. The escape space 21 can ensure that the operator has enough room for movement, avoid contact between the legs or other parts of the body and the base 2, and improve the safety and comfort of the operation.

[0050] Preferably, if Figure 1 As shown, the welding workbench further includes a drawer assembly 6, which is disposed on the base 2. The drawer assembly 6 provides additional storage space for the welding workbench, and can conveniently take and put various tools, accessories, consumables, etc., which helps to keep the workbench clean and orderly, and reduces the time spent by the operator to take and put tools, etc., thereby improving work efficiency. In this embodiment, there are two drawer assemblies 6, which are disposed on both sides of the avoidance space 21. At this time, the drawer assembly 6 is on the same side as the position where the operator is working, which makes it easier for the operator to take and put various tools, accessories, consumables, etc.

[0051] Specifically, Figure 1 As shown, the moving wheel 3 includes a wheel body 31 and a buckle 32, and the buckle 32 can limit the rotation of the wheel body 31. When the welding workbench needs to be moved, the buckle 32 is unlocked so that the wheel body 31 can rotate; when arriving at the designated location, the buckle 32 is buckled down, and it is confirmed that the welding workbench is stable and does not shake as a whole. In some embodiments, the wheel body 31 is a universal wheel; in other embodiments, the wheel body 31 is a fixed wheel. In this embodiment, the wheel body 31 on one side is a universal wheel, and the wheel body 31 on the other side is a fixed wheel. The free rotation and variable direction characteristics of the universal wheel can complete the steering action more quickly and smoothly, thereby improving the controllability and safety of the vehicle. The fixed wheel can only roll in one direction, which helps to provide stability and support for straight-line travel. When the universal wheel is turned, the fixed wheel can maintain stable straight-line travel to ensure the overall stability of the welding work.

[0052] Preferably, if Figure 1 As shown, the second platform 12 is provided with a boss 121 along its outer contour in a direction away from the base 2. The power interface can be fixed on the boss 121, and the boss 121 provides a clear positioning and fixed position for the power connector, ensuring the stable placement of the power connector on the welding workbench, and the design of the boss 121 makes the installation and removal of the power connector more convenient, and the operator can more easily fix the power connector on the boss 121, thereby improving work efficiency.

[0053] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
