Rotating track pressing device for cross sliding table

The invention discloses a rotating track pressing device for a cross sliding table. The rotating track pressing device comprises a clamp trolley garage track and a working track which are perpendicular to each other. A rotating disc is arranged at the intersection of the clamp trolley garage track and the working track, two switching rails which are perpendicular to each other are arranged on therotating disc, the front end of each switching rail is provided with a side lateral block extending to one side, and a powerful clamping air cylinder is arranged on the side close to the joint of oneswitching rail and the working track. When a telescopic air cylinder drives the rotating disc to rotate until the switching rails are in butt joint with the working track, the powerful clamping air cylinder drives a rotating swing arm to rotatably press down, the front end of a pressing block is in pressing connection with the upper end faces of the lateral positioning blocks at the front ends ofthe switching rails, and th
