Base for horizontal numerical control lathe and operation method thereof

Abstract

The invention provides a base for a horizontal numerical control lathe and an operation method thereof. The base comprises a shell-shaped base body; a translation station and a rotating station are arranged on the top face of the base body; a power motor is fixedly arranged in the base body below the translation station; a heat dissipation exhaust fan is fixedly installed at the tail end of the power motor; an exhaust outlet of the heat dissipation exhaust fan is connected with an exhaust pipe; an air outlet of the exhaust pipe is arranged on the side wall of the base body; a semi-arc groove is arranged on the top face of the rotating station; a rotating shaft box is fixedly installed in the semi-arc groove; a cylinder body of the lower half portion of the rotating shaft box is embedded into the semi-arc groove, and a U-shaped gap is reserved between the cylinder body and the groove wall of the semi-arc groove; a main shaft is rotatably connected into the rotating shaft box in a penetrating mode; the outer end of the main shaft is fixedly connected with a chuck; a driving shaft of the power motor is connected with the main shaft through a transmission assembly. A heat dissipation and exhaust system is arranged in the base, thermal deformation of the base caused by high temperature can be reduced, and therefore the machining precision performance of a machine tool is improved; and the rotating shaft box is surrounded by a gap, heat is not prone to being transmitted to the base, and deformation of the rotating shaft box and the base due to temperature rise is reduced.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a lathe component, in particular to a base for a horizontal numerically controlled lathe and an operation method thereof. Background technique [0002] CNC lathe is a high-precision, high-efficiency automatic machine tool. Equipped with a multi-station turret or a power turret, the machine tool has a wide range of processing performance, and can process complex workpieces such as straight cylinders, oblique cylinders, arcs, and various threads, grooves, and worms. Complement various compensation functions, and play a good economic effect in the mass production of complex parts. [0003] The heat dissipation system of the existing horizontal CNC lathe is not perfect, so that the heat generated by the motor operation cannot be dissipated in time, resulting in deformation of the base due to poor internal air circulation and untimely heat dissipation, thereby affecting the precision...

Problems solved by technology

[0003] The heat dissipation system of the existing horizontal CNC lathe is not perfect, so that the heat generated by the motor operation cannot be dissipated in time, resulting in deformation of the base due to poor internal air circulation and untimely heat dissipation, thus affecting the precision performance of the machine tool

In addition, the existing spindle box is designed as a whole, the circumference of the spindle box surrounds the spindle, and the mating surface of the spindle box and the base is far away from the spindle, so that the heat generated during the high-speed rotation of the spindle is easy to concentrate in the spindle box, and the heat dissipation effect is better. Poor, causing the spindle box to affect the performance of the machine tool due to temperature rise and deformation
