The invention discloses a moving worktable for a double-thread hob experiment, comprising a driving motor, a hydraulic cylinder and bearings. The moving worktable is characterized by being arranged at one axial end above a base; bearing blocks are arranged at two ends in the radial middle above the moving worktable; two guide rail grooves are arranged at two radial ends above the moving worktable in parallel; a connecting flange is arranged on an axial side of the moving worktable and is connected with a piston rod of the hydraulic cylinder; the hydraulic cylinder is fixed at the adaptive position of the base; tow guide rail grooves are arranged at two axial ends above the base in parallel; driving screws are fixed on the bearing blocks through the bearings; one end of each driving screw is connected with the driving motor fixed on the moving worktable; a test piece table is arranged above the moving worktable; the middle of the lower end of the test piece table spans across the driving screws and is connected with the driving screws; guide rails arranged at the bottom of the test piece table are matched with the guide rail grooves above the moving worktable; and guide rails arranged at the bottom of the moving worktable are matched with the guide rail grooves above the base.
