[0002] Machining centers can be divided into vertical machining centers and horizontal machining centers. Horizontal machining centers have complex structures, occupy a large area, and are more expensive. In addition, horizontal machining centers are inconvenient to observe during machining, and it is inconvenient to clamp and measure parts. Therefore, vertical machining centers are more widely used at present. Vertical machining centers refer to machining centers with vertical spindles.

[0003] In the prior art, a utility model patent with publication number CN 219704543 U proposes a high-efficiency vertical machining center CNC machine tool, which has a fixed table under the workbench, and the workbench can be replaced, so when processing the next product, the product to be processed can be placed in a suitable position on another workbench in advance, and the processing can continue after the previous product is processed, which saves time and improves efficiency;

[0004] However, it does not have the ability to automatically switch between multiple workstations. Each time the workpiece is processed, it is necessary to stop the machine and replace the workbench before continuing the processing. Frequent disassembly and assembly of the workbench is troublesome, which not only increases the workload but also easily wastes more time. At the same time, it does not have the ability to clamp and limit the workpiece. During processing, the workpiece is prone to position displacement and sliding, affecting the processing quality and accuracy. Therefore, we need to upgrade and transform on the basis of existing technologies to overcome its existing problems and shortcomings. Utility Model Content

[0025] Preferably, the rotating assembly 3 includes a turntable 31, a gear ring 32 is fixed at the lower end of the turntable 31, a rack rod 33 is meshed on one side of the gear ring 32, a side block 34 is fixed on one side of the rack rod 33, and a telescopic cylinder 35 is connected to one end of the side block 34. The turntable 31 is rotatably located on the workbench 2, the gear ring 32, the rack rod 33 and the telescopic cylinder 35 are all located in the inner groove of the workbench 2, and the vertical frame 5 movably penetrates the turntable 31 and the gear ring 32;

[0026] The rack rod 33 can be driven to move by the telescopic cylinder 35, and the gear ring 32 can be driven to rotate by the rack rod 33, thereby driving the turntable 31 to rotate on the workbench 2, so as to switch the positions of the two groups of placement tables 81 on the upper end of the turntable 31, so as to directly switch to another group for operation after one group of workpieces is processed, without disassembling any parts.

[0027] Preferably, the clamping assembly 8 includes a placement table 81, a bidirectional screw 82 is rotatably provided inside the placement table 81, a worm gear 83 is provided in the middle of the bidirectional screw 82, a worm 84 is meshed at the lower end of the worm gear 83, and a knob 841 is provided at one end of the worm 84, two sets of movable plates 85 are screwed oppositely on the bidirectional screw 82, the placement table 81 is installed at the upper end of the translation guide rail 4, the knob 841 is rotated and located outside the placement table 81, the upper end of the movable plate 85 is slidably located on the placement table 81, and a protective pad 851 is installed on the inner side of the movable plate 85, two sets of guide blocks 86 are symmetrically provided at the lower end of the movable plate 85, two sets of guide grooves 87 are opened on the placement table 81, and the two sets of guide blocks 86 are respectively slidably located in the guide grooves 87 on both sides;
