Provided is an upright column and power head structure of a single-arm boring and milling machine, which is structured in such a manner that a guide rail is properly arranged at the inner side of a gate-shaped upright column and a power head is arranged at the inner side of the gate-shaped upright column via the guide rail. When being assembled, the power head must be capable of sliding up and down. The main motor and the power head are properly installed and a turbine worm reducer is installed on the top of the gate-shaped upright column, with one end of the adjusting leading screw hinged to the power head and the other end connected to the screw thread inside the turbine worm reducer.
Description
technical field [0001] The invention relates to a structure of a column and a power head of a milling machine, in particular to a structure of a column and a power head of a single-arm boring and milling machine, belonging to the technical field of metal cutting machine tools. Background technique [0002] At present, in the structure of the column and the power head of the single-arm boring and milling machine at home and abroad, the structure of the cantilever is adopted. The main advantage of this mechanism is that it is easy to install and maintain. However, since the power head is mounted on the column in a cantilever Installation, the power head itself has a certain weight, and there is a huge cutting reaction force in the work, so it is easy to reduce the geometric accuracy between the power head and the column, not only the service life of the machine tool is reduced, but also the parts in processing Reduced quality. Contents of the invention [0003] The object o...
