MACHINE TOOL WORKING TABLE STRUCTURE AND DRILLING AND TAPPING MACHINE

摘要

Disclosed are a machine tool working table structure and a drilling and tapping machine having the working table structure. The machine tool working table structure includes: a working platform (1) and a saddle (3), wherein the working platform (1) is arranged above the saddle (3), and a sliding table (2) is arranged between the working platform (1) and the saddle (3); and a rack (5) is arranged below the working platform (1), a rack (6) is arranged above the saddle (3), gears (4) are arranged on the sliding table (2), the gears (4) on the sliding table (2) engage with the rack (5) of the working platform (1) and the rack (6) of the saddle (3) at the same time, and are driven by an electric motor, and the working platform (1) moves relative to the saddle (3) in a straight line where the racks (5, 6) are located. In the present application, the operating stroke of the machine tool working platform is doubled, but there is only a very small increase in the complete machine specifications, the volume and costs of the machine tool.
