WIPO Patent Application WO/2007/099632
Kind Code:
A1
Abstract:
A machine tool main spindle balancer that stably pulls and urges a main spindle
unit upward to reliably and effectively reduce a load for lifting a means for lifting
the main spindle unit, that can be easily applied to existing machine tools, that
is excellent in durability and is downsized, and that can be constructed in a simple
structure to make the balancer advantageous in production costs. The main spindle
balancer (30) has a gas spring (31) having a cylinder body (32), a rod (33), and
compressed gas. The gas spring (31) is placed above the main spindle unit (10).
The lower end of the rod (33) is connected to the main spindle unit (10) so that the
rod (33) can pull and urges the main spindle unit (10) upward by urging force acting
on the rod (33) of the gas spring (31). The urging force by the gas spring (31) reduced
a load on a lifting mechanism (20).
