[0022] Please refer to Figures 1 to 5 The anti-floating clamping device 100 for a machine tool of the present invention includes a base 1, a moving part 2, a first pressing plate 3 and a second pressing plate 4. The base 1 and the moving part 2 are both horizontal plate structures. The moving part 2 is located above the base 1, and the first pressing plate 3 and the second pressing plate 4 are located above the moving part 2. The moving part 2 is slidably arranged on the base 1. The first pressing plate 3 and the second pressing plate 4 are symmetrically arranged. The first pressing plate 3 is connected to the moving part 2, and the second pressing plate 4 is connected to the moving part 2. The first pressing plate 3 extends outward to form a first extension portion 31. The first extension portion 31 is an up and down step structure. The lower step of the first extension portion 31 is recessed inward and has a first arcuate surface 311, a first plane 312, and a first guide slope 313, which are sequentially connected. The second pressing plate 4 extends outward to form a second extension portion 41, which has an upper and lower stepped structure. The lower step of the second extension portion 41 is recessed inward and has a second arcuate surface 411, a second plane 412, and a second guide slope 413, which are sequentially connected. The upper and lower stepped structures of the first pressing plate 3 and the second pressing plate 4 can precisely fit the two corners of the workpiece and cover its upper surface, thereby preventing the workpiece from floating during machining and improving machining accuracy. Because the first extension portion 31 has a first arcuate surface 311, a first flat surface 312, and a first guide slope 313, while the second extension portion 41 has a second arcuate surface 411, a second flat surface 412, and a second guide slope 413, the first guide slope 313 and the second guide slope 413 can together form an open structure for guidance, thereby guiding the entry and positioning of the workpiece. The anti-floating clamping device 100 for machine tools provided by the present invention also has the advantage of a simple structure. More specifically, as follows:

[0023] Please refer to Figures 1 to 4The first pressing plate 3 also includes a first connecting portion 32, which is connected to the movable part 2, and the first connecting portion 32 and the first extension portion 31 are perpendicular to each other. Preferably, the first connecting portion 32 and the first extension portion 31 together form an "L"-shaped structure. The second pressing plate 4 also includes a second connecting portion 42, which is connected to the movable part 2, and the second connecting portion 42 and the second extension portion 41 are perpendicular to each other. The second connecting portion 42 and the second extension portion 41 together form an "L"-shaped structure. This makes it possible to clamp the two sides of the workpiece, thereby forming a positioning.

[0024] Please refer to Figures 1 to 4 The anti-floating clamping device 100 for a machine tool further includes a movable drive device 5 mounted on the base 1. The movable member 2 is mounted at the output end of the movable drive device 5. The movable member 2 moves under the drive of the movable drive device 5. Preferably, the movable drive device 5 is a cylinder or a motor drive device, but is not limited thereto. Specifically, the movable drive device 5 is connected to the base 1 via a connector 6.

[0025] Please refer to Figures 1 to 4 The anti-floating clamping device 100 for a machine tool further includes a guide assembly 7, which includes a slide rail 71 and a slider 72. The slider 72 is connected to the movable member 2, and the slide rail 71 is connected to the base 1. The slider 72 is slidably mounted on the slide rail 71. Preferably, two sets of guide assemblies 7 are provided, and the two guide assemblies 7 are symmetrically arranged, but the present invention is not limited thereto. This allows the movable member 2 to move more smoothly relative to the base 1.
