Definitions

  • This invention relates to the mounting of carriages for machine-tools, such as, for example, vertical lathes, planing machines, planing-milling-machines, and radial drilling machines and more particularly to the mounting of carriages supported by and movable along horizontal slideways and provided with compensatory rollers resting resiliently on roller tracks parallel to the said slideways in order to relieve these slideways of the load as far as possible.
  • machine-tools such as, for example, vertical lathes, planing machines, planing-milling-machines, and radial drilling machines and more particularly to the mounting of carriages supported by and movable along horizontal slideways and provided with compensatory rollers resting resiliently on roller tracks parallel to the said slideways in order to relieve these slideways of the load as far as possible.
  • the invention relates to a device which uses a particular form of roller track and of roller, as well as to a particular mounting of the said roller, which does not offer the aforesaid disadvantages.
  • the roller which has a circumferential groove of a circular arc section is freely movable axially, and rolls on a bar, rod or the like of complementary section.
  • the roller bar is cylindrical and rests on the rail member supporting the carriage on two faces forming a dihedral angle with one another.
  • the said roller bar is simply placed into the said dihedral angle, and retained longitudinally by a fixed abutment arranged at each end.
  • Figure 1 shows diagrammaticaly in transverse section a carriage movable on a horizontal rail and provided with a compensator device with rollers according to the invention.
  • Figure 2 shows on a larger scale details of the mounting of the roller according to Figure l
  • Figure 3 is a view of the profile of the device represented in Figure 2, as viewed in the direction of the arrow 1.
  • 1 represents a horizontal rail for example the rail of a planing machine having two vertical pillars between which the rail 1 spans.
  • a car- 2,832,651 Patented Apr. 29, 1958 riage 2 designed to carry the tools (not shown) can slide on this rail along the slideway 3.
  • a cylindrical bar 4 is arranged parallel to the slideway 3.
  • a roller 5 which is resiliently mounted in a box 6 fixed firmly on the carriage 2 by a bracket 7 maintained on the upper face of the carriage, for example, by means of screws 8.
  • the bar 4 is accordingly lodged in the dihedral angle formed by the two plane faces 11 and 12 of the rail. It is simply put into this angle which it cannot leave since it is forced therein by the roller and it is retained, as a safety measure, in the longitudinal direction by any convenient device such as an abutment 25 integral with the rail at each of the ends of the bar 4.
  • the box 6 in which the roller is mounted has a cylindrical bore 14 in which a piston 15 can slide.
  • a stud 16 fitted transversely in the piston 15 supports the roller 5 through a needle bearing 17 in such a manner as to allow the roller 5 to undergo, if necessary, slight axial displacements along the stud 16.
  • the upper portion of the piston 15 is provided with a centering boss 18 on which is mounted a pile of strong resilient washers 21 of the Belleville type. This pile of washers bears, on the one hand, on the upper face of the piston 15 and, on the other hand, on the inner face of a very strong cover 19 through an intermediate rigid regulating washer 22.
  • the cover 19 is fixed to the box 6 by meansof screws 23.
  • the functioning of the device is clear.
  • the Belleville washers 21 force the roller 5 strongly against its roller track constituted by the cylindrical bar 4.
