Definitions

  • the invention relates to a screw clamp according to the preamble of claim 1.
  • the proposed screw clamp construction ensures that workpieces can be reliably clamped, the surfaces of which are not to be clamped to one another are parallel and, if desired, workpieces can also be clamped with an exact right angle with respect to the slide rail. Alignment links must then be used for this purpose, which are to be inserted into extended parts of the guide opening between the support piece and the slide rail.
  • the invention has for its object a screw clamp To further develop according to the preamble of claim 1 so that it can always be clamped at right angles with respect to the slide rail and to make the required precise guidance of the support piece on the slide rail technically particularly simple.
  • the support piece of the screw clamp according to the invention is accordingly guided at right angles by means of alignment members on the slide rail, which take over their guiding function as soon as a workpiece is clamped between the fixed bracket and the support piece.
  • the support piece it is provided to equip it with a support body formed by an integrally formed sheet-metal stamped part, between the legs of which the slide rail extends and the aligning members are arranged.
  • this support body is advantageously arranged within a housing which is expediently made of plastic and which at the same time has a flat workpiece support surface opposite the fixed bracket.
  • This plastic housing can be designed in the manner of a cap which can be pushed onto the supporting body and which can be pushed onto the supporting body from the front end, for example. Accordingly, it is advantageous to form the plastic housing closed at least at the front end of the support piece.
  • a particularly advantageous embodiment of the support body is the subject of claim 6.
  • This construction enables a particularly favorable arrangement and mutual connection of plastic housing and support body by the connecting web connecting the two legs of the support body can also be used for anchoring the plastic housing, for which purpose laterally by Approaches of the plastic housing is overlapped.
  • the plastic housing also assumes the guiding function of the support piece on the slide rail, in that the slot provided in it is widened over an area to a recess that fits the slide rail. This makes it possible to dispense with the use of the legs of the support body at the same time for a guide on the slide rail that is stable against tilting about the longitudinal axis of the support piece.
  • a further type to be used with preference provides for the alignment members to be designed, whereby on the one hand interchangeability of the alignment members between the legs of the supporting body is easily possible and on the other hand the support piece on the slide rail can also be kept tiltable by removing the rollers, so that workpieces with non-parallel surfaces can also be clamped.
  • the support piece and the fixed bracket can be combined into one structural unit by realizing features 8 and 9.
  • a steel slide rail of the screw clamp is designated, on the upper end of which according to FIG. 1 a fixed bracket 12 is provided.
  • This fixed bracket is assigned a support piece, which is designated as a whole by 14 and is displaceably arranged on the slide rail.
  • the fixed bracket and the support piece each have clamping surfaces 20, 20 'or 22, 22' adjacent to the longitudinal edges 16, 18 of the slide rail, the length of the clamping surfaces 20 ', 22' being substantially smaller than the length of the clamping surfaces 20, 22.
  • FIG. 24 designates as a whole a support bracket which, according to FIG. 1, is provided on the side of the support piece 14 facing away from the fixed bracket and is displaceable on the slide rail 10 and can be locked by tilting.
  • the support piece 14 has a support body 26 formed by a deformed sheet metal stamping, which has two legs 28, 30 arranged at a parallel distance from one another and which are rigidly connected to one another by a connecting web 32.
  • the slide rail extends in the rear area of the support piece approximately in the middle of the legs through the support body and its connecting web is located both at a distance from the front end of the legs 28, 30 and at a short distance from the slide rail 10.
  • the guidance of the support piece 14 on the slide rail is designed such that its clamping surfaces 22, 22 'are essentially at right angles in every phase of an adjustment movement and when clamping a workpiece with respect to the slide rail.
  • This can be accomplished by at least two alignment members, which are arranged within the support body 26, ie between the legs 28, 30 such that they press against the longitudinal edges 16, 18 of the slide rails when clamping a workpiece.
  • one of the alignment members 34 according to FIG. 1, in the upper region of the support body approximately between the slide rail and connecting web 32 and the other alignment member designated 36, viewed in the longitudinal direction of the slide rail 10, arranged at a distance therefrom and on the opposite longitudinal edge 18 would be the slide rail.
  • a further alignment member 34 'or 36' is assigned to these alignment members in the same plane, but on the opposite longitudinal edge of the slide rail, all of which abut the longitudinal edges of the rails.
  • the distance between the upper and the lower pair of alignment members is chosen to be relatively large in order to achieve the most favorable conditions with regard to the required force absorption.
  • the legs 28, 30 of the support body 26 in the region of the slide rail are each equipped with a projection 38, which extends downwards according to FIG. 1, between which the alignment members 36, 36 'are held.
  • the alignment g songs are for example formed by hollow cylindrical rollers 42 which are rotatably supported on held between the legs of the support body cylindrical bearing pins 44th
  • the alignment members are for example formed by hollow cylindrical rollers 42 which are rotatably supported on held between the legs of the support body cylindrical bearing pins 44th
  • another embodiment is also conceivable, and one is explained below with reference to FIG. 5.
  • the support body 26 is located within a plastic housing, which is designated as a whole by 46. This is U-shaped in cross section, its lateral legs 48, 50 covering the legs of the support body from the outside and also encompassing the lower leg edges with a thickened section 48 'or 50'.
  • the connecting web 54 of the plastic housing which connects the lateral legs 48, 50 to one another, forms the clamping surfaces 22, 22 'on its outside.
  • the plastic housing has the maximum height of the support body legs 28, 30 and preferably covers the lower lugs 38, 40 of the legs 28, 30 of the support body on the outside thereof, so that the lugs 38, 40 are not in view.
  • the plastic housing is closed at its front end by an end wall 60. It takes over the guidance of the support piece 14 in such a way that it is guided on the slide rail about its longitudinal axis in a substantially stable manner.
  • an opening 62 provided in the connecting web 54 and penetrated by the slide rail assumes a guiding function, which is why it lies closely against the flat sides of the slide rail.
  • this opening tapers to a slot 64 which is accessible from the front end of the plastic housing.
  • this is to be pushed onto the support body from the front or right front end of the support body in accordance with FIG. 1 until the end wall 60 on the right end face of the legs 28, 30 in accordance with FIG. 1. comes to the plant.
  • a threaded spindle 66 which is guided in the support bracket 24 at the front end thereof and is rotatably held with a ball head 68 in a socket 70 of a pressure transmission piece 72, is used to clamp a workpiece between the fixed bracket and the support piece.
  • the pressure transmission piece consists for example of a shaped body made of steel, which by means of mutually opposite retaining webs 74, 76 in from the front end of the support body legs 28,; 30 accessible slots 78 and 80 is held.
  • 82 denotes support webs that extend in the direction of the pressure transmission piece and rest on its upper side, which are molded onto the connecting web 54 of the plastic housing 46.
  • the bracket 24 is in the embodiment shown between the two pairs of alignment members 34, 34 ', 36, 36' on the slide rail and slidably dimensioned so that it can intervene between the legs of the plastic housing.
  • the support bracket and support piece thus form a certain structural unit, the required reaction force when clamping a workpiece being generated solely by the support bracket, in which it wedges with its guide on the slide rail when the threaded spindle 66 is tightened.
  • the distance between the two pairs of aligning members 34 to 36 can also be chosen only so large that the arrangement of the support bracket 24 is to be provided below the lower pair of aligning members on the slide rail.
  • contact pieces can be provided, which interact with the sliding rail flat sides in a friction-locking manner.
  • the parts 14 and 24 thus run into each other to save space and support and cover each other.
  • the support piece and support bracket can thus be inserted into the enveloping plastic housing 46 and are held in this in particular by the bearing pins 44.
  • the bearing pins can e.g. be designed eccentrically so that the rollers 42 can be lifted off the slide rail by twisting in order to enable the support piece 14 to tilt and thus also to clamp workpieces with inclined contact surfaces.
  • rollers 42 as alignment members also allows the production of a screw clamp in the simplest manner, the support member of which adjusts to inclined contact surfaces of workpieces if the arrangement of the rollers 42 on the bearing pin 44 is dispensed with during their assembly.
  • the basic concept of the screw clamp construction according to the invention thus also allows the production of screw clamps which only clamp in parallel and which only adapt to inclined workpiece surfaces.
  • the legs 28, 30 of the support body 26 interconnecting connecting web 32 extends to the right end of the support body according to FIG. 4, thereby achieving a particularly stable construction which enables workpieces to be reliably positioned even between relatively narrow areas of the clamping surfaces of fixed bracket and support piece, which are located adjacent to the flat sides of the slide rail 10.
  • the slide rail can also serve as a workpiece system as well as a ruler.
  • Fig. 5 shows a further possible embodiment of alignment members for parallel guidance of the support member 14.
  • the alignment members designated 90 have a flat contact surface 92 and are axially displaceable but rotatable in the support member 14, for example by a polygonal, in particular rectangular cross-sectional shape can be adjusted.
  • the contact surface 92 is in frictional contact with the adjacent longitudinal edge of the slide rail 10, so that the clamping surface 22 of the support piece 14 parallel to the clamping surface 20 of the fixed bracket 5 is aligned, while after the axial adjustment of the alignment members, as shown in FIG. 5 to the right, they come out of contact with the slide rail, so that the support piece 14 can tip over in order to be able to clamp workpieces, the surfaces of which on the fixed bracket and support piece do not face each other are parallel.
