Lathe workbench floating clamping mechanism

The utility model provides a floating clamping mechanism for a lathe workbench, and relates to the technical field of clamping mechanisms. The lathe workbench floating clamping mechanism comprises a workbench installed at the top of a base, a clamping device is arranged at the bottom of the workbench, clamping assemblies are arranged on the two sides of the clamping device, the clamping device comprises two installation frames, and a fixing plate is fixedly connected to the bottom, close to the base, of each installation frame. One mounting frame is far away from the other mounting frame, so that the gap between the two mounting frames is increased, the space for dismounting the friction pad is completed, replacement and mounting are facilitated, and after the replacement and mounting are completed, the lead screw is rotated reversely to drive the mounting frame to be close to the other mounting frame, and resetting is completed. And when the bottoms of the two mounting frames are fixedly connected with the m
