They are widely used in machining, assembly operations, and automated production lines, primarily to ensure workpiece stability during processing, improve machining accuracy and efficiency, and guarantee operator safety.

[0003] Utility model patent CN222873876U discloses a CNC machine tool fixture, including a support assembly, a support plate, a support plate, a load-bearing assembly, a load-bearing plate, a hydraulic cylinder, and a clamping assembly. The support plate is located at the middle position above the support plate and near one end. One end of the crossbeam is fixed with a connecting plate rotatably connected to the support plate. A bidirectional screw rotates inside the crossbeam. A servo motor driving the bidirectional screw is installed on one side of the crossbeam. Clamping plates are inserted into one side of the crossbeam and near both sides, and the clamping plates and the bidirectional screw are threadedly connected. However, when clamping workpieces, this device or traditional hydraulic fixtures can only fix large or small workpieces, and cannot achieve the function of clamping workpieces of both large and small sizes. Therefore, there is an urgent need for a hydraulic fixture platform that can clamp both large and small workpieces. Utility Model Content

[0041] The shelf 16 is connected to the center of the top of the operating table.

[0042] Implementation process: When clamping a large workpiece, firstly, control the sliding ends of the first hydraulic cylinder 5 and the second hydraulic cylinder 6 to slide, causing the first sliding frame 7 and the second sliding frame 8 to slide on the first guide slide 3 and the second guide slide 4. This moves the first positioning rod 23 and the second positioning rod 24 at the bottom of the first sliding frame 7 and the second sliding frame 8 to above the positioning hole 15 closest to the clamping position. Then, control the extension ends of the first cylinder 11 and the second cylinder 12 to extend, causing the first drive rod 17 to push the second drive rod 18 to push the third drive rod 19 to move. At this time, the third drive rod 19 moves downward. Since the maximum diameter of the first positioning rod 23 and the second positioning rod 24 is the same as that of the positioning hole 15, a bevel design is adopted, which makes it easier for the first positioning rod 23 and the second positioning rod 24 to move straight. The first positioning rod 23 and the second positioning rod 24 are inserted into the positioning hole 15 to improve the stability of the first sliding frame 7 and the second sliding frame 8, and to prevent the third hydraulic cylinder 13 and the fourth hydraulic cylinder 14 from acting on the first sliding frame 7 and the second sliding frame 8 when generating clamping force, thus preventing insufficient clamping force. Then, the telescopic ends of the third hydraulic cylinder 13 and the fourth hydraulic cylinder 14 are extended to clamp the workpiece. If the workpiece size is small, the first sliding frame 7 and the second sliding frame 8 are pushed to a more central position to minimize the space between the first sliding frame 7 and the second sliding frame 8. Then, the telescopic ends of the third hydraulic cylinder 13 and the fourth hydraulic cylinder 14 are extended to clamp the workpiece.
