Abstract
The invention provides an annular hydraulic cylinder locking mechanism for locking a working table needing rotary adjustment of a machine tool, especially for locking a side-suspended rotary working table, when large locking force is needed. An annular hydraulic cylinder sleeves a rotary shaft connected with the working table and axially positioned between a clamping ring and the box wall of a machine base box body by limiting and thrusting the clamping ring. When hydraulic oil of a hydraulic cylinder system enters an oil cylinder, a piston produces axial thrust to lock the working table. When reversing pressure relief is performed on the hydraulic oil, the piston pressure is eliminated, and the working table can be rotatably adjusted. The annular hydraulic cylinder locking mechanism uses the annular hydraulic cylinder as a locking execution element, the cross area of the oil cylinder can be designed to be large, locking force of the oil cylinder is increased, locking stress is evenly distributed, the stressed locking mechanism does not deform harmfully, locking control is convenient, and the locking mechanism is safe and reliable.
