Definitions

  • ABSTRACT another the inlets of the table alternately and successively communicate with the remaining outlets of the passages of the column.
  • the present invention relates to metal-cutting machines and, more particularly, the invention relates to vertical multiple spindle machines.
  • the invention can be most successfully used for large-series production of articles, particularly in the automotive and tractor industries.
  • the oil is forced continuously, in which case the oil is delivered from the openings of the passages of the column into the receiving channels of the revolving table through a circular groove on the tapered portion of the column.
  • the oil is forced under a pressure of 29,1740;kgf/crn?v through the circular grooyehaving a diameter'df sub-1,000 mm, considerable leakage of oil occurs through the gap between the conjugated surfaces of the table and column which is required for the provision of free rotation of the table about the column.
  • the supply slots communicating with the passages of the column have a considerable length, of the order of one-tenthto one-fifteenth of the perimeter of the conjugated surfaces, because the sum of the lengths of the supply slots must be somewhat greater than the distance between the receiving channels along the conjugated surfaces of the table and column.
  • the above-mentioned construction contributes to reduction of the oil leakage over the conjugated surfaces of the table and column, yet in this case, too, the leakage is considerable.
  • oil spots i.e., portions filled with oil under a pressure of 40 kgf/cm. This causes complex deformations of the table and its misalignment relative to the stationary column.
  • An object of the present invention is to eliminate the above-mentioned disadvantages.
  • Another object of the invention is to provide a vertical multiple spindle machine having such a mutual disposition of the outlets of the oil supply passages and the inlets of the revolving table that the leakage of oil through the gap between the conjugated surfaces of the column and table is minimized.
  • Still another object of the invention is to provide a machine of the above type in which a stable position of the revolving table relative to the stationary column is constantly maintained.
  • Yet another object of the invention is to provide such a system of a multiple spindle machine which will ensure high accuracy of workpieces being machined.
  • a proposed vertical multiple spindle machine in which the revolving table carrying the hydraulic clamping means is mounted with its central aperture on the tapered portion of a stationary column having along its perimeter outlets of supply passages for oil forced under pressure into the inlets of the table disposed at the level of said outlets and interconnected through an annular channel, which inlets communicate respectively with the hydraulic devices.
  • the outlets of the passages of the column and the inlets of the table which are positioned at the same level, are located so that in each fixed position of the table its regular inlet communicates with the same outlet of the passage of the column, while in the process of revolving the table from one fixed position to another its inlets alternately and successively communicate with the remaining outlets of the passages.
  • the inlets of the table are preferably disposed at an equal angular pitch relative to each other along the perimeter of the conjugated surface of the tapered portion while the outlets of the passages are preferably spaced through an unequal angular pitch so that, when the outlet of one passage coincides with the inlet of the table, the outlets of the other passages of the column are displaced with respect to the adjacent inlets in the direction of rotation of the table through constant angles the magnitudes of which are not equal and constitute a progression.
  • FIG. 1 is a front view, partly in section, of the vertical multiple spindle machine according to the invention
  • FIG. 2 is a diagram of mutual layout of the outlets of the passages of the column and the inlets of the table according to the invention.
  • the proposed vertical multiple spindle machine has a revolving table 1 (FIG.'1) carrying hydraulic means A for clamping the workpieces to be machined.
  • the table with its central aperture is mounted on the conical portion B of a stationary column 2.
  • the tapered portion has along its perimeter outlets 3 of passages 4 feeding oil which is forced into the inlets of the table disposed at. the same level as said outlets 3.
  • the inlets 5 correspondingly communicate with the above-said hydraulic clampingmeans.
  • the outlets 3 of the passages 4 of the column 2 and the inlets 5 are laid out at the same level and are arranged so that in each fixed position of the table 1 a regular inlet 5a (FIG. 2) of the table communicates with the same outlet 3a of the passage, while in the process of revolving the table inthe direction of the arrow C from one fixed position to another its inlets 5b through 5h alternately and, successively communicate with the remaining outlets 3b, 3c, 3d of the passages 4.
  • the inlets 5a through 5h of the table 1 along the perimeter of the surface of the column 2 conjugated with the tapered portion B of the column are arranged at an equal angular pitch relative to-each other.
  • outlets 3 of the passages of the column are spaced through an unequal angular pitch so that at a coincidence of the outlet 3a of one passage 4 with the inlet 5a of the table 1 the outlets 3b, 3c, 3d of the remaining passages are displaced relative to the adjacent inlets 5b, 5d, 5f of the table in the direction of its rotation indicated by the arrow C through constant angles a a a the magnitudes of which are not equal and constitute a progression.
  • the angle a, between the outlet 3b and the inlet 5b is equal to- 45/4, i.e., to the angle of rotation of the table from one fixed position to another divided by the number of the outlets of the passages of the column; the angle a between the outlet 3c and the inlet 5d is equal to 2(45l4), while the angle a between the outlet 3d and the inlet if is equal to 3(45/4).
  • the passages 4 of the stationary column 2 are connected to the pump 6 of the hydraulic system of the machine.
  • the inlets are interconnected by a circular channel 7 with intermediate control valves (not shown). Therefore the process of supplying oil from the inlets 5 of the table 1 to the hydraulic clamping means A is not described herein.
  • oil is fed into the remaining inlets 5b, 50 through 5h of the table through the annular channel 7.
  • all the inlets 5a, 5b through 5h are symmetrically disposed along the perimeter of the surface of conjugation of the table and column and are filled with oil under pressure. As a result, the forces of the oil pressure between the inlets of the table and the adjacent portion of the conjugated surface of the column acting both on the table and the column are balanced, and this eliminates misalignments and deformations of the table.
  • This provides for a stable position of the table relative to the column, which, in turn, provides for high accuracy of the workpieces being machined.
  • a vertical multiple spindle machine having a stationary column with a mounting portion atone end; hydraulic clamping means for fixing workpieces to be machined, an indexible table carrying said hydraulic clamping means, said table being rotatably supported on said column by a central aperture complimentary to said mounting portion of the column; passage means for feeding oil under pressure into said column; said passage means having outlets about the perimeter of said mounting portion of the column; said indexible table having inlets communicating with said hydraulic clamping means; a circular channel formed in said table and communicating with all of the inlets in the table; said outlets of the passage means of said column and said inlets of the table being disposed at the same level and being so arranged that in each fixed position of said table only one of said inlets communicates with one of said outlets of the passage means of said column, said outlets and said inlets being angularly spaced about said column and said table respectively so that during the rotation of said table from one fixed position to another its inlets alternately and successively communicate with the remaining outlets of the passage means of the column.
