Description

Technical Field

[0001] The utility model relates to the technical field of machining equipment, in particular to an underground workbench. Background Art

[0002] Workbenches, as equipment for workpiece processing, are often used for welding, cutting, and grinding. During these operations, the workpieces must be clamped and secured to the workbench. Existing workbenches are typically horizontal, so when welding, only flat welding is possible. Workpieces requiring vertical welding cannot be processed using these workbenches. Furthermore, workbenches often occupy a significant amount of production space at the processing site, resulting in significant waste of space if left idle.

[0003] Therefore, it is necessary to provide an underground workbench to solve the above technical problems. Utility Model Content

[0004] The purpose of the utility model is to address the deficiencies in the existing technology and provide an underground workbench that can reduce the difficulty of welding and convert vertical welding and overhead welding into flat welding on the workbench. At the same time, the workbench can be sunk until it is flush with the ground when idle, saving production space.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An underground workbench comprises a workbench, a bracket fixed below the workbench, and a flip assembly mounted on the side of the bracket. The flip assembly comprises a flip seat, a flip shaft, and a flip hydraulic cylinder fixed to the outside of the flip seat. One end of the flip shaft is connected to the output end of the flip hydraulic cylinder and pivotally connected to the flip seat, and the other end of the flip shaft is fixed to the bracket. An underground lifting assembly is mounted below the bracket. The underground lifting assembly comprises a lifting hydraulic cylinder and support guide posts, the support guide posts comprising upper and lower guide posts. A crossbeam is fixed between the movable end of the lifting hydraulic cylinder and the upper guide post, and the flip seat is fixed to the top of the upper guide post. The underground lifting assembly allows the workbench to be lowered to ground level when idle, saving production space. The flip assembly allows the workbench to have a variety of processing angles, allowing it to meet different operating methods as needed.

[0007] Preferably, the workbench has a through-hole, a rotating base fixedly attached to the bottom surface of the workbench along the edge of the through-hole, a rotating motor fixedly attached to the interior of the rotating base, and an output end of the rotating motor extends through the workbench along the through-hole, and the output end of the rotating motor is detachably connected to the rotating base. Installing a detachable rotating base above the workbench can meet the requirements of spin welding and reduce the difficulty of spin welding. When the workbench is not in use, the rotating base can be removed to ensure that the workbench is flush with the ground after being lowered, without any protrusions.

[0008] Preferably, the rotating table is circular and has a T-slot.

[0009] Preferably, the workbench is rectangular and is provided with T-slots and mounting holes, which facilitate clamping of different types of workpieces.

[0010] Preferably, the lifting hydraulic cylinder and the supporting guide column are both arranged on the base plate.

[0011] Preferably, the support guide columns are provided in two sets, one mounted on the left and right sides of the lifting hydraulic cylinder. A flip seat is fixed to the top of each support guide column, and a flip shaft is fixed to the left and right sides of the bracket, each pivotally connected to the flip seat on the same side. The symmetrical arrangement of the flip seat, flip shaft, and support guide columns ensures smoother operation of the workbench.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. By setting a flip component on the side of the bracket, the workbench can be flipped at multiple angles according to processing requirements. The workpiece can be clamped and fixed on the workbench, which can complete more difficult welding such as vertical welding and overhead welding. Vertical welding and overhead welding can be converted into flat welding, reducing the difficulty of welding.

[0014] 2. Install an underground lifting assembly under the workbench. When the workbench is needed, the workbench rises with the cooperation of the underground lifting assembly until it reaches the working height. When the workbench is idle, the workbench descends until it is flush with the ground to ensure that it does not occupy production space when idle.

[0015] 3. Install a rotary table above the workbench, and drive the rotary table to rotate through the rotary motor to meet the needs of workpiece rotation welding and reduce the difficulty of welding. BRIEF DESCRIPTION OF THE DRAWINGS
