In order to reduce the sliding friction between the positioning ring 13 and the indicating rod 15, a plurality of rolling balls 17 are embedded in the positioning ring 13, the inner periphery of the positioning ring 13 and the outer periphery of the indicating rod 15 are gap matched, and the rolling balls 17 realize rolling friction. The lower side of the roller track assembly 5 is fixedly provided with a lifting hydraulic slide 19, the machine table 1 is provided with a hydraulic cavity 20 accommodating the lifting hydraulic slide 19, and the lifting hydraulic slide 19 linearly slides in the hydraulic cavity 20. The lifting hydraulic slide 19 adopts a piston rod structure with a circular cross section, the hydraulic cavity 20 is cylindrical, and the hydraulic cavities 20 corresponding to the two groups of roller track assemblies 5 are communicated through a hydraulic pump 200 and a pipeline. The lower end of the track 7 is fixed on the lifting hydraulic slide 19. The machine table 1 is provided with a positioning seat 21, the positioning seat 21 is longitudinally provided with a sliding seat 22, the end of the indicating rod 15 is rotatably connected with the sliding seat 22 through a bearing, and the indicating mechanism 16 comprises a reset spring 23 located at the upper and lower ends of the sliding seat 22 and a pressure sensor 18 located between the outer end of the reset spring 23 and the positioning seat 21.
