Apparatus for feeding damping fluid into guide tubes in multiple-spindle turning machines and the like

A feed device for a turning machine, comprising:

• a spindle drum having a central axis;
• a plurality of guide tubes each having an opening therein and a first end which faces away from said spindle drum;
• a holding plate having a plurality of axial passage bores therein, a front side facing toward said spindle drum, and a rear side facing away from said spindle drum, said first end of each of said plurality of guide tubes being fastened to and mounted in a corresponding one of said axial passage bores;
• a supporting frame;
• a bearing, disposed in said supporting frame, which supports said holding plate thereby allowing said holding plate to rotate about said central axis of said spindle drum;
• a connecting line in communication with said plurality of guide tubes;
• a common supply line connected to said connecting line for supplying damping fluid to said plurality of guide tubes;
• a cover plate, disposed proximate said firs ends on said rear side of said holding plate, which covers said holding plate at least up to a diameter within which said plurality of guide tubes are disposed, said cover plate being coupled to said supporting frame so that it cannot rotate;
• a seal disposed between said holding plate and said cover plate so that said rear side of said holding plate is sealed from the external environment;
• wherein said connecting line is disposed between said holding plate and said cover plate and serves as a distribution passage for supplying damping fluid to said openings of said plurality of guide tubes, and said cover plate has a first passage bore therein which connects said common supply line to said distribution passage.
