Definitions

  • This invention relates to improvements to the devices for the protection of the guiding surfaces or slides of machine tools such ashorizontal lathes, turret lathes, grinding machines, boring machines and the like, on which slide one or more members, for instance one or more carriages. a puppet-head, a grinding-wheel head or other parts.
  • One of these known arrangements comprises a fixedmetallic cover-plate secured at its both ends respectively to the puppet-head and to the opposed end of the bed, slits being cut in the car- Said cover protects only partially the guiding surfaces, which remain exposed to the projected matter at the spot where the chips accumulate more specially: between two slides.
  • This arrangement has furthermore the disadvantage of allowing the flushing water to infiltrate between cover and slide, which water carries along impurities liable to cause the Wear of the slides and impairing their proper lubrication.
  • Another known protection system consists of covers secured upon the arms of the carriage orcarriages and sliding with them. They extend beyond the ends of the bed in the extreme positions of the carriage to which they are fastened, which increases the floor-space needed for the machine.
  • the object of this invention is to provide an efilcient protection of the slides against any projection or accumulation of chips and to give the covers a. perfect stiffness, which protects them against any accidental fall of a heavy body.
  • Figure 2 is a top view of the same'and Figure 3 is a view seen in direction of arrow F in Figure 1.
  • Y is a view seen in direction of arrow F in Figure 1.
  • I is the carriage of a machine tool and 2 the slides of the machine being a part of the bed and carriage I being adapted to slide on them.
  • a cover plate 3 is secured, for instance by means of screws 4, upon the portion of the bed adjacent to each slide 2.
  • Said cover 3 enters a slit 5 provided in carriage I and shaped so that cover 3 is surrounded to a. great extent by the material of the carriage.
  • the cover is secured at regular spaces to the bed upon the entire length of the latter andits extension does in no case exceed the length'of the machine.
  • the cover opposes any entrance of chips from inside of the bed. Its width may be such that it entirely overhangs the slide whereby an efficient protection is secured.
  • the fastening of the cover upon the slide takes preferably place upon bosses 6 leaving between themselves open spaces I, so that in case a foreign body enters accidentally through the void shown in A, it is immediately removed through said open spaces 1.
  • thickness of the cover may be chosen'so as to warrant the highest mechanical resistance without any resulting disadvantage as to deflection.
  • a machine tool having a bed, parallel guide surfaces forming part of said bed, and a. carriage to travel on said guide surfaces, the combination of a plurality of spaced inwardly projecting bosses provided on said bed parallel to and below the inner edge of each of said guide surfaces, and, for each guide surface.
