Full-automatic tapping machine with high machining precision for precision mechanical engineering

The high-machining-precision full-automatic tapping machine for precision mechanical engineering comprises a base, the left side of the top of the base is fixedly connected with a fixing base, the top of the fixing base is fixedly connected with a tapping machine body, and the bottom of an inner cavity of the fixing base is fixedly connected with an air cylinder; the top of the air cylinder is fixedly connected with a lifting plate. According to the full-automatic tapping machine, the base, the fixing base, the tapping machine body, the air cylinder, the lifting plate, the supporting column, the workbench, the first limiting block, the threaded rod, the threaded sleeve and the second limiting block are used in cooperation, and the problems that in the using process of a traditional full-automatic tapping machine for precision mechanical engineering, a workpiece to be machined is inconvenient to limit and fix, and the machining precision is high can be effectively solved. According to the device, the tapping s
