Definitions

  • the invention relates to a machine vice according to the preamble of claim 7.
  • a machine vice of the type specified above has become known, for example, by US 5 163 662 A.
  • Such a machine vice serves, for example, Workpieces on the processing table of a machine tool to clamp so that the workpiece can be machined.
  • the invention has for its object a machine vice of the genus specified above to further develop any interference from chips or the like, be reduced entirely or by largely so that the operating times are increased.
  • the base body has at least one lateral, elongated chip exit opening, so that the chips falling down from the workpiece and get into the area of the covered spindle, from which Machine vice can escape.
  • This onward transport the chips can be made in different ways. It can do that the drilling fluid can be used. But it is also possible remove the chips with compressed air. It can also be mechanical Means are used. The location of the chip exit openings makes the removal of the chips much easier.
  • Chip exit opening It is favorable if there is one on each side of the base body Chip exit opening is arranged.
  • the cross section for the Chip outflow is thereby increased.
  • a chip exit opening can also be provided in the bottom of the base body, wherein it is of course important that the clamping surfaces are appropriate Has cutouts for the chip passage.
  • a chip scraper is arranged on the bottom of the base body that interacts with the bottom of the sled and limits the area of the elongated chip exit openings.
  • This chip scraper which is preferably V-shaped is, the chips direct and reduce the chip exit openings the possibility of further transport in the area of Spindle that has the thread.
  • V-shaped chip scraper interacts with flat surfaces on the underside of the slide. Such surfaces are easy to work with and it will also prevents the carriage from moving through its movement Noteworthy chips. It is advantageous if the dimensions of the carriage under the spindle are only slight to avoid that the carriage moves the chips in the Takes the area of the chip exit openings and compresses.
  • the first scraper to match the cylindrical part of the Spindle interacts, preferably has a wiper lip, so that it is practically impossible for chips to enter the carriage bore penetrate, which receives and surrounds the spindle.
  • the second stripper is preferably the thread shape of the Adjusted spindle, so in particular partially engages in the threads and clean the thread before this part of the Spindle comes into contact with the spindle nut.
  • this second scraper immediately is attached to the threaded nut.
  • the machine vise shown essentially exists from a base body 9, which has approximately a U-shaped shape, as can be seen from the illustrations in FIGS. 6 and 7.
  • the base body encloses the carriage 6 is movable by the spindle 1.
  • the spindle drive 23 has a polygon 24. With a suitable crank, over a power amplifier, not shown, the spindle 1 be rotated.
  • This spindle has two areas, namely the area 2, which is essentially a cylindrical outer surface has and the area 3 with the thread 4th
  • the spindle nut 17 is part of the carriage 6 and in this Spindle nut engages spindle 1 in area 3.
  • the area 3 is immersed in the Carriage bore 5, which so far encloses the spindle, while the smooth area 2 is visible from above.
  • Two clamping jaws are arranged on the machine vice, namely the clamping jaw 25, which is firmly mounted on the base body is, and the jaw 26, which is connected to the carriage and thereby, for example, from the position of FIG. 1 in the position of FIG. 3 is adjustable.
  • Each of the jaws 25 and 26 can also be implemented if desired (Compare Fig. 5), which increases the span of the machine vice change, especially enlarge, lets.
  • the clamping jaw is fastened by means not shown in detail Screws.
  • a V-shaped chip scraper 11 is provided.
  • This chip scraper has a lower plate 27 for attachment on the floor 14.
  • the chip scraper 11 provided with a strip element 29, the upper edge with the surfaces 12 of the carriage 6 cooperate.
  • To be safe Interact and also easy to manufacture To reach areas, these are just designed.
  • the carriage 6 has a depression 28, near the Spindle nut 17 a stripper 8.
  • This stripper is the Adapted shape of the thread 4 of the spindle and prevents Chips reach the area of the spindle nut 17.
  • This scraper 7 has a lip 16 which on the movement of the carriage on the The outer surface of the area 2 of the spindle 1 slides along.
  • the first scraper 7 and the second scraper 8 hold the Hole 29 of the spindle 1 practically free of chips.
  • the arrangement ensures stable guidance of the Carriage 6, although through the chip exit openings 10 a Reduction of the section modulus and also the moment of inertia occurs in the base body 9.
  • the adverse effects In this respect, the chip exit openings 10 are very small. It has been found that those inevitable in the tensioning process minor changes in position of the workpiece by the described Arrangement of the openings at least partially compensated become.
