Definitions

  • the invention relates to jaws for vices in particular with parallel clamping support elements and a compensating filling for clamping and fixing objects and workpieces for the purpose of. B. a machining.
  • the object of the invention is to overcome the disadvantages of the prior art and to create a vice jaw which, with a simple and stable construction, enables firm and positionally precise clamping of differently shaped workpieces.
  • the essential aspect of the invention in practice is that pressure elements act on the closed compensating filling, which are detachably connected to interchangeable clamping supports located in recesses, these recesses having axes parallel to the clamping direction. Widened heads of the pressure elements sit in depressions in these recesses, so that the pressure elements can only be moved together with the tensioning supports in the direction of the compensation filling during tensioning.
  • the narrower end part of the pressure elements is with the interchangeable tensioning supports - e.g. B. by means of continuous screws - connected.
  • a variety of clamping supports can z. B. be arranged in rows.
  • a major advantage of the vice jaw according to the invention is that not only existing clamping supports, but also only a few selected supports are used for clamping, and these clamping supports can be exchanged for other (e.g. smooth, grooved, prismatic or special) supports without difficulty.
  • the jaw shown is for fixed mounting on a vice or vice using z.
  • B. determined screws, which are screwed into conical holes on a normal jaw or on a suitable insert.
  • the vice jaw shown contains a rectangular solid body 1, each with an upper and lower rear projecting approach 1a, 1b.
  • a plate-shaped compensating filling 3 is arranged in a recess in the body 1 and is covered on the back by a plate 2 fixed between the two shoulders 1a, 1b.
  • Continuous transverse recesses are arranged in the body 1 in two parallel longitudinal rows, the rear end section of which is widened toward the compensation filling 3. In these end sections of the transverse recesses sit pressure pieces 4, the widened heads 4a abut the compensating filling 3 on the end face.
  • longitudinally displaceable tensioning supports 5 are arranged in the transverse recesses with widened (square) heads 5a protruding from the body 1 at the front, the tubular inner end section of which surrounds the narrower section of the pressure piece 4 and is supported on the end face on the radial surface of the widened head part 4a .
  • a screw 6 with a countersunk head is arranged in a central bore in each tensioning support 5 and is screwed with its threaded section into a threaded blind bore 4b in the narrower part of the pressure piece 4.
  • the clamping pieces 5 can be adjusted axially or exchanged for other clamping pieces with specially shaped head parts 5a, without the clamping jaw having to be dismantled.
  • the tensioning supports 5 are secured against arbitrary rotation in the transverse recesses, which is achieved by appropriate shaping of their shaft or, in a technically simpler manner, by lateral positioning of their polygonal head 5a on a web 1c of the body 1.
  • the maximum compensation capacity of the clamping jaw is determined by the position of the maximum extension of the clamping supports 5 and the position in which their heads 5a come into contact with the body 1. A desired range in this sense can be achieved by the difference between the volume for the compensation filling 3 in the body 1 and the volume of the latter.
  • clamping jaw described can of course be modified within the scope of the invention, the technical and functional principle of which also applies to other types of Clamping devices can be applied, e.g. B. the clamping of workpieces on pallets or workpiece tables of machine tools, presses, handling machines, or the like.
