Definitions

  • the invention relates to an edge clamp, in particular for pressing edge parts onto edges of workpieces running between an upper side and a lower side, comprising a clamp body, a first clamping jaws which can be placed on the upper side of the workpiece and a second clamping jaws which can be placed on the underside of the workpiece for fixing the Clamp body on the workpiece and a clamping pressure generating device which can be actuated by means of an actuating element for loading an edge pressure element acting on the edge part.
  • edge clamps All clamping tools are referred to as "edge clamps", which are used, for example, to press edge profiles or so-called edge banding on the edges of panels.
  • edge clamps As a rule, the plates are held by the top and bottom of such edge clamps and an additional spindle is provided, which serves to press the edge profile or the edging against the edge with pressure.
  • Tools are also known which are attached to a rail of a commercially available screw clamp with a wing screw or a similar element and either one Have a spindle which extends at right angles to the rail and can be guided asymmetrically to the side of the rail past the edge of the workpiece or have two spindles which run at right angles to the rail and run symmetrically on both sides of the rail in the direction of the edge.
  • Another edge clamp which has become known comprises a C-shaped clamp body, on the upper and lower side limbs of which a spindle is adjustably arranged in a nut thread in order to press the clamping jaws against the workpiece and thus fix the clamp body on the workpiece.
  • a third spindle is provided, which is adjustably arranged in the middle part of the clamp body and serves to adjust the edge pressure element in the direction of the edge and thus to act on the edge part.
  • An edge clamp is also known from DE-U-88 00461, in which the clamping jaws fixing the workpiece can be swiveled in a spiral and have a non-slip support. These clamping jaws endeavor to reduce their distance due to their spiral shape as soon as pressure is exerted on the edge part and thus the workpiece with the edge pressure element. A torsion spring guides these jaws back into their original system. This tool has the disadvantage that when the edge clamp is attached it is necessary to move the clamping jaws to such an extent that they begin to fix the workpiece. Only then is it possible to apply the edge pressure element to the edge part.
  • the invention is therefore based on the object of creating an edge clamp of the generic type which is as simple as possible to handle and can be securely fixed to the workpiece.
  • the advantage of the solution according to the invention can be seen in the fact that, due to the displaceability of the clamping jaws along the guides in the guide directions thereof, the clamping jaws are on the one hand easily movable and, on the other hand, a direction of movement of the clamping jaws can be predetermined in a simple manner by the guide direction, in such a way that a secure fixing of the Workpiece with the jaws is possible.
  • the clamping jaws can be designed in such a way that they rest flatly, preferably over a large area, on the workpiece and thus allow secure clamping without damaging the workpiece. It is particularly favorable if the clamp body is approximately C-shaped and the workpiece overlaps with its first side leg on the top and with its second side leg on the underside and that the guides are arranged on the side legs.
  • Different directions of movement of the jaws can be realized with the guides according to the invention.
  • a particularly advantageous embodiment provides, however, that the clamping jaws in the guides can be moved towards the workpiece in a clamping direction and at the same time can be moved in a transverse direction transverse to the clamping direction. With this movement in the transverse direction transverse to the clamping direction there is the possibility of achieving additional advantageous effects when clamping the workpiece by means of the clamping jaws.
  • An advantageous exemplary embodiment provides that the clamping jaws in the guides can additionally be moved in the direction of the transverse direction towards the edge pressure element during a movement in the clamping direction.
  • This solution has the particular advantage that it can still be used to support the pressing of the edge part on the workpiece when clamping the workpiece between the clamping jaws.
  • Another alternative solution provides that the clamping jaws in the guides can also be moved away from the edge pressure element in the direction of the transverse direction when moving in the clamping direction. This solution has the advantage that this movement of the jaws reinforces the The workpiece is then clamped between the jaws when the edge pressure element also acts on the workpiece via the edge part.
  • a particularly advantageous exemplary embodiment provides, however, that a displacement element is provided which can be moved relative to the clamp body with a clamping jaw actuating device and with which the clamping jaws can be moved along the guides.
  • a sliding element has the great advantage that, on the one hand, a defined and coupled movement of the clamping jaws can be generated and, on the other hand, there is also the possibility of moving the clamping jaws along their guides in a metered, force-actuated manner.
  • the displacement element can be implemented in a wide variety of ways.
  • a particularly favorable solution provides that the displacement element has a transverse arm which can be moved by the clamping jaw actuating device relative to the clamp body and extends transversely thereto and which acts on the clamping jaws via side arms. By moving the cross arm, a correlated movement of the clamping jaws on the two side legs of the clamp body can thus be generated in the guides.
  • the displacement element can be designed in a wide variety of ways. For example, it is conceivable to design the displacement element so that the side arms are rigidly connected to the cross arm.
  • the clamping jaws are only guided in the respective guide directions or are additionally oriented in a defined manner.
  • the clamping jaws are guided through an alignment element. It is conceivable either to design the displacement element as an alignment element, which thus defines the alignment of the clamping jaws relative to one another.
  • the guides are designed as alignment elements and that the clamping jaws are guided so that they can move in a defined manner in the guide directions.
  • the clamping jaws can be fixed in the alignment elements in several positions.
  • clamping jaws have clamping jaw bodies guided in the guides. It is conceivable that the jaw body itself carry clamping surfaces and can therefore be placed directly on the workpiece.
  • clamping surface carriers are held on the clamping jaw bodies, which support the clamping surfaces.
  • clamping surface carriers could be firmly connected to the clamping jaw bodies.
  • clamping surface carrier so that they by means of parallelogram-like links to the Clamping jaw bodies are stored. This makes it possible to move the clamping surface carriers relative to the clamping jaw bodies and also to specify a defined alignment of the clamping surfaces.
  • a particularly expedient solution provides that the clamping surface carriers can be moved relative to the clamping jaw bodies from a position in contact with them into a tension-increasing position lifted off the clamping jaw bodies.
  • the parallelogram-like links could in principle act as a parallelogram, so that the orientation of the clamping surface when the clamping surface bodies are in contact with the clamping jaw bodies is approximately the same as the orientation when the clamping surface carriers are in a raised position from the clamping jaw bodies.
  • a particularly expedient solution provides that the clamping surface of the clamping surface carrier in the position lifted from the clamping jaw body is inclined at an angle with respect to the position lying against the clamping jaw body. With such a solution it is possible to create additional effects by changing the inclination of the clamping surface.
  • a particularly favorable solution provides that the inclination of the clamping surface in the position raised from the jaw body an expansion of the side legs is at least partially compensated. This means that if the jaw carriers lift off the jaw bodies and thus increase the tension of the workpiece, the accompanying expansion of the side legs of the clamp body can be compensated for by the fact that the inclination of the clamping surfaces is also changed and thus ultimately also with expanding side legs then the clamping surfaces essentially maintain the original orientation relative to the workpiece, ie in the simplest case they are still oriented parallel to one another.
  • a particularly favorable solution provides that the clamping surface carriers can be moved away from the edge pressure element when moving from the position in contact with the clamping jaw body into the position raised from the clamping jaw body. This makes it possible to use the pressure effect of the edge pressure element in such a way that the clamping surface carriers which are already tensioning the workpiece move in the same direction of pressure due to the pressure effect of the edge pressure element and thereby have a stress-increasing effect on the clamping surfaces and thus the workpiece.
  • clamping surfaces are metallic surfaces.
  • the clamping surfaces have elastic supports. By these elastic pads there is the possibility of compressing the pads and thus also to achieve an increased clamping of the workpiece.
  • a particularly advantageous embodiment provides that the supports are made of a non-slip material that engages the workpiece, since in this case a quick and safe first clamping of the workpiece is possible and a final, secure clamping of the workpiece is then still available by further force.
  • a particularly advantageous embodiment provides that the supports comprise an elastomer material.
  • an advantageous exemplary embodiment provides that the supports comprise a soft material.
  • An advantageous exemplary embodiment provides that the clamp body carries the edge pressure element, that is to say that the edge pressure element is supported on the clamp body.
  • the movement of the clamping jaws takes place in the transverse direction in the direction of the edge pressure element, that is to say that when the workpiece is clamped, the clamping jaws also move in the direction move to the edge pressure element and thus the clamping of the workpiece between the clamping jaws is accompanied by pressurization of the edge part, in particular if the edge part is already in contact with the edge pressure element before the clamping jaws abut the workpiece, since the clamping jaws move in the direction of the final clamping of the workpiece move the edge pressure element and thus also press the workpiece with the edge part against the edge pressure element.
  • the clamping surfaces are provided with elastic supports, since in particular then the elasticity of the supports allows an additional path of the clamping jaws in the direction of the edge pressure element, which particularly advantageously creates the possibility of exerting the necessary pressure on the edge part in order to to press it against the workpiece.
  • the edge pressure element is a part that can be moved relative to the clamp body, in particular by means of the clamping pressure generating device, so that there is additional mobility of the edge pressure element relative to the clamp body, which makes it particularly easy to clamp the workpiece by means of the clamping jaws or after clamping the workpiece by means of the clamping jaws to apply sufficient pressure on the edge pressure element to the edge part.
  • a particularly advantageous solution provides, however, that with one actuating element both the workpiece is clamped between the clamping jaws and the clamping pressure generating device is actuated, so that the edge clamp according to the invention is particularly easy to handle and operate.
  • the actuating element could be designed so that it performs different functions through different actuation, so that, for example, two hands are required to actuate the actuating element on the edge clamp.
  • a particularly advantageous solution provides that the actuating element is designed as a one-handed operation.
  • a particularly advantageous solution provides that both the clamping jaw actuating device and the clamping pressure generating device can be actuated with the actuating element.
  • actuating element can be coupled to the jaw actuating device with a releasable coupling. That means that about the clutch the actuation of the clamping jaw actuating device can be realized by coupling to the actuating element or can also be interrupted, namely by releasing the coupling.
  • This clutch can be operated manually, for example, that is, by operating a corresponding handle.
  • a particularly advantageous embodiment provides, however, that the coupling is designed as a self-releasing coupling when the workpiece is clamped between the clamping jaws, which means that no separate actuation of the coupling is required, but rather the coupling itself when the workpiece is clamped between the clamping jaws triggers and thus the actuation of the jaw actuating device is interrupted.
  • the coupling can be designed in different ways.
  • the coupling can be actuated via a mechanical activation or deactivation device which detects whether the workpiece is clamped between the clamping jaws or not.
  • the clutch is designed as a slip clutch, that is to say that when the clamping jaw actuating device opposes a large resistance to the actuating element, since the workpiece is fixed between the clamping jaws, the coupling is decoupled by triggering the slip clutch Actuating element and clamping base actuating device can be realized.
  • the clamping pressure generating device comprises a clamping spindle.
  • the clamping jaw actuating device comprises an adjusting spindle with which the displacement element can be moved relative to the clamp body.
  • Such an adjusting spindle is preferably designed such that it interacts with an axial bearing as the first force application point and with a spindle nut as the second force application point, these two force application points serving to move the displacement element relative to the clamp body.
  • the force application points can, for example, be arranged rigidly both on the displacement element and on the clamp body.
  • An expedient solution provides that one of the force application points acts on the displacement element via an elastic element, that is to say that the elastic element creates the possibility of blocking the movement of the displacement element by virtue of the fact that the clamping jaws already clamp the workpiece firmly to be able to turn the spindle further and thus to store an elastic force in the elastic element, which always applies a force to the displacement element, even if, for example, tolerances should result in a flexibility in the tension of the workpiece.
  • Another advantageous solution provides that one of the force application points acts on the clamp body via an elastic element.
  • one of the force application points acts on the clamp body via an elastic element.
  • a structurally particularly simple solution provides that the adjusting spindle forms the clamping spindle at the same time.
  • an elastic element between the clamp body and the corresponding force application point of the adjusting spindle is particularly advantageous, since in this case the adjusting spindle can be used to act as a clamping spindle at the same time, namely with deformation of the elastic element and thus an additional one Generate action on the clamping pressure element.
  • the edge clamp according to the invention has on the one hand an adjusting spindle for fixing the workpiece between the clamping jaws and on the other hand a clamping spindle for pressurizing the edge pressure element, which does not necessarily have to be operable by a single actuating element
  • the adjusting spindle and the Clamping spindles are arranged coaxially to one another, since a particularly favorable constructive realization of the clamping jaw actuating device and the clamping pressure generating device can thus be realized.
  • two actuating elements which are coaxial to one another can be provided, namely one for the adjusting spindle and one for the clamping spindle.
  • a particularly favorable solution also provides that the clamping spindle is designed as an inner spindle to the adjusting spindle and can be displaced relative to the adjusting spindle in the direction of the spindle axis. In this case, the arrangement of the clamping spindle and adjusting spindle is compact.
  • a particularly simple actuation of the clamping spindle is possible in this case if the actuating element for the clamping spindle is rotatably mounted on the adjusting spindle.
  • the clamping spindle can be displaced relative to the actuating element in the direction of the spindle axis, but is connected to the latter in a rotationally fixed manner.
  • Some embodiments of the solution according to the invention have the particular advantage that an edge clamp can be realized, which is to be operated above all with one hand, so that the edge part to be fastened, for example the edge band, can be held with the free hand and that the edge clamp is also designed such that that a yielding of the clamping force on the edge band and thus a slipping on the two sides of the workpiece is not possible.
  • some embodiments of the solution according to the invention create the possibility of not acting on the edge part, for example the edge of the edge, with a rotating movement, and this with the largest possible area in order to enable better pressure distribution.
  • the force is applied to an end edge of the edge part with a spindle which is customary in screw clamps, but not directly with the pressure plate which is usual in screw clamps onto the edge part or the edge, but via a displaceable pressure piece.
  • This pressure piece can also be swiveled in order to be able to also press on shaped profiles.
  • the nut thread of the spindle nut can be arranged in the middle part of the C-shaped clamp housing.
  • the clamping jaws are positively guided in the C-shaped clamp body or housing on each side leg in such a way that they can be opened and closed in accordance with the spindle movement and can be moved so far apart that they extend over an edge of the workpiece Have the protruding edge band raised, both when placing the edge clamp on the workpiece and when removing it.

  • the inevitable movements of the clamping jaws can be predetermined by means of longitudinal recesses arranged on the displacement element, the center line of which runs perpendicular to the spindle axis, that is to say in the fixed clamping direction.
  • the clamp body for the rotationally secure, inevitable movement of the clamping jaws is provided with longitudinal recesses which run obliquely in the guide direction and which form the guides.
