[0030] In the use of the vertical hydraulic fixture device with integral lifting function, first, according to the specific specifications and size of the workpiece to be processed, the height of the fixture needs to be accurately adjusted. Start the hydraulic cylinder 18, its output shaft generates a push or pull force, drive the support plate 4 fixedly connected with it inside the frame 2 to slide smoothly up and down, so as to realize the flexible adjustment of the overall height of the fixture. The sliding of the support plate 4 synchronously drives the several fixed plates 5 fixedly connected with the top of it and the hydraulic oil cylinder 6 and the clamp plate 7 closely connected with it to rise and fall synchronously, ensuring that the fixture can be accurately positioned to the height position required by the workpiece, laying a solid foundation for the subsequent clamping operation. After the height adjustment is completed, the limit inner sleeve 13 is slid to the appropriate position inside the limit outer sleeve 14 by manual or mechanical method, and the plug rod 15 is inserted into the corresponding plug slot 16 on the limit outer sleeve 14 and the limit inner sleeve 13 to realize the stable locking of the support plate 4 and the whole fixture device. This step effectively prevents the height change caused by vibration or external force during processing, ensuring the processing accuracy and stability.
