Abstract: Aiming at adjusting locking mechanism of high precision track of towing tank, the rail adjustment, the rail straightness, the adjustable levelness mechanism and the fixation of adjustable bearing were studied. Using the 3D design software CREO2.0, the model of the adjustable inclined block type lock mechanism and the detached adjustable lock mechanism was built. Based on the solid model, the working principles of the above two mechanisms were described. Through the theoretical analysis of the horizontal and vertical adjustment range, locking force and anchorage, it was put forward that the detached adjustable lock mechanism used in the high precision,high speed and dynamic lock rail design construction,but not adaptable for adjustable inclined block type lock mechanism. Practical application results show that the detached adjustable lock mechanism is superior to the traditional inclined block type lock mechanism in the aspects of the track accuracy, the stability of the track and the later maintenance.
