Definitions

  • the invention relates to a tensioning device according to the preamble of patent claim 1.
  • a clamping device for tools which consists of a holder to be attached to a work table and a tool holder which can be detachably connected to it.
  • the tool holder has an articulated ball-like attachment for connection to a compatible slotted clamping ring and a conical attachment attachment with its axis perpendicular to the attachment axis for connection to at least one compatible attachment device of the holder.
  • the holder consists of a fixed part to be fixed on the table and a pivotable part which is articulated to the fixed part and can be locked and pivoted, the pivoting part having the fastening device for the tool holder.
  • a disadvantage of this known clamping device is that its individual parts can only be pivoted relative to one another to a limited extent. The application area of the device is thus relatively limited. Due to its structure, the known device is also particularly suitable for holding light workpieces; for heavier or more heavily loaded tools, the clamping device is hardly suitable because of the undesired adjustment that then easily occurs even in the locked state.
  • the device should also enable the immediate clamping of a tool without the tool holder being interposed.
  • This design of the device and its swivel part enables the fastening device for the tool holder to be freely positioned within the limits of the swivel range, so that any number of positions can be set in which the swivel part can be locked in its position.
  • the tool holder is pivotable on the one hand together with the swivel part and on the other hand rotatable about the axis of its attachment.
  • the swivel part can be swiveled from a horizontal basic position in which it rests on the fixed part, for example by 90 ° into a vertical position and by a further 90 ° into a second horizontal position.
  • the swivel part In its basic position, the swivel part is supported on its underside and can therefore also absorb very high loads in the vertical direction. By swiveling through 90 ° from the basic position, a position perpendicular to the basic position is achieved. In addition, the swivel part can be swiveled by a further 90 °. This does indeed result in a direction of the swivel part which corresponds to that of the basic position; but the pivoting part no longer lies on the fixed part, but is pivoted away from it, so that further clamping possibilities open up.
  • the fixed part of the holder is expediently a screw clamp with a table support leg and an approximately perpendicular vertical leg, and the pivot axis preferably runs in the corner region formed by the two legs approximately parallel to the adjacent edge of the table clamped by the screw clamp.
  • the fastening device of the pivoting part of the holder for the tool holder is a clamping ring which corresponds in its inner diameter to the clamping ring of the tool holder, and the fastening attachment of the tool holder is a cylindrical pin which fits the clamping ring of the holder. This ensures that tools that can be inserted into the tool holder can also be clamped directly into the swivel part.
  • the swivel axis also serves to lock the swivel part.
  • the two clamp legs are essentially plate-shaped with a vertical slot H of width H running approximately centrally in the plates over part of the plate length and passing through the corner region, in that the corner region has a recess in its central part, which hinge-like takes up a pierced extension of the pivoting part with little play, and that through the corner region of the legs and the extension a clamping screw forming the pivot axis is guided in a threaded bore in its end region facing away from the screw head.
  • a simple wrench is sufficient to actuate the screw, as is contained in every home improvement or workshop equipment.
  • a preferred embodiment provides that, in addition to locking the swivel part, the clamping ring of the swivel part is also tensioned by means of the tensioning screw.
  • the slot of the clamping ring of the swivel part of the holder runs parallel to the slot in the fixed part of the holder through the shoulder and has a width h that is less than the width H of the slot in the fixed part. It can be locked in one easy movement of the pivoting part and its clamping ring are actuated, so that, in addition to the great variability of the clamping device, it is also easy to manufacture and very easy to use.
  • the embodiment of the clamping device shown in this figure without a tool holder essentially consists of a fixed part 2 and a pivoting part 3 pivotally connected to it.
  • the fixed part 2 has the shape of a screw clamp with a table support leg 21, a vertical leg running at right angles thereto 22, a clamping leg 23, which in turn extends at right angles to this, and a clamping screw 23 'with an actuating handle 23 "which is guided through the latter leg 23.
  • the underside 21 of the table support leg 21 lies on a work table 5 which is formed from a wooden plate 51.
  • the inside of the vertical leg 22 bears against the front edge 52 of the table 5.
  • the clamping screw 23 ' the fixed part 2 is firmly clamped to the table 5 in the manner of a screw clamp, with a very plate-like design of the legs 21 and 22 stable position of the fixed part 2 is ensured.
  • the pivot part 3 which is connected in an articulated manner to the fixed part 2, can be pivoted about a pivot axis 30 relative to the fixed part 2, which runs through the corner region 20 formed by the two legs 21 and 22.
  • the pivot axis 30 consists of a screw 27 which is guided in a bore 26 'and at the same time runs through a pierced extension 33 of the pivot part 3, which results in a stable hinge.
  • the pivot part 3 consists essentially of a clamping ring 31 with a central opening 32 for receiving a suitable attachment of the tool holder.
  • the shape and function of the swivel part 3 and its interaction with the tool holder are explained in more detail with reference to the figures yet to be described.
  • a marking line 36 is attached to the swivel part 3, on which, in cooperation with an invisible degree scale attached in the corner region 20 of the fixed part 2, certain angular positions of the swivel part 3 can be read.
  • the bottom of the swivel part 3 lies flat on the table support leg 21 of the fixed part 2. From there it can be pivoted about the pivot axis 30, the pivot angle being at least 90 ° and preferably even i80 ° .
  • the fixed part 2 can also be fastened to the table 5 by means of screws which can be guided from above through bores 29 through the table support leg 21.
  • FIG. 2 shows the tensioning device from FIG. I in a frontal view, the swivel part 3 being in a vertical position, ie pivoted upward from the basic position by 90 ° .
  • the vertical leg 22 and the clamping screw 23 'with its actuating handle 23 can be seen here from the fixed part 2.
  • the fixed part 2 is in turn clamped to the work table 5 by means of the clamping screw 23', of which the front edge 52 of the wooden plate 51 is visible in this illustration .
  • a slot 24 runs approximately centrally in the vertical leg 22 from the corner region 20 over part of the length of the leg 22. Furthermore, in the corner region 20 there is a recess 25 in the central region thereof, which serves to receive the extension 33 of the pivot part 3.
  • An aligned bore 26, 35, 26 ' runs through the corner region 20 and the shoulder 33, through which the screw 27 is guided. At one end, the screw 27 has a head 27, which is supported by a washer 28, for receiving a wrench. At the end of the screw 27 facing away from the head, the bore 26 'has a suitable mating thread.
  • the pivoting part 3 which - as already mentioned - essentially consists of the clamping ring 31 with its central opening 32, has in its lower part a slot 34 running parallel to the slot 24 through the clamping ring 31 and the extension 33.
  • This slot 34 has a relatively small width h, while the slot 24 in the vertical leg 22 of the fixed part 2 has a larger width H.
  • the pivot part 3 can be pivoted about the pivot axis 30, realized by the screw 27.
  • the diameter of the opening 32 is expanded sufficiently by the slot 34 in order to be able to use the tool holder with a corresponding extension piece.
  • the screw 27 By actuating the screw 27 in the tightening direction, the slot 34 is closed and the slot 24 is narrowed in width until a tool holder inserted into the clamping ring 31 of the swivel part 3 is firmly clamped and until at the same time the swivel part 3 is moved from the outside to the two sides of the Approach 33 acting clamping force is locked in position.
  • the screw 27 thus fulfills three functions at the same time, namely that of the pivot axis 30, the locking device for the pivot part 3 and the clamping screw for the clamping ring 31.
  • FIG. 3 shows a top view of the device I, that the slot 24 extending from the corner region 20 also extends over part of the length of the table support leg 21. Furthermore, the bores 29 for carrying out screws for fastening the fixed part 2 to the wooden plate 51 of the work table 5 can be seen in the table support leg 21.
  • pivot axis 30 or the screw 27 runs parallel to the table edge 52 immediately in front of it, so that depending on the pivoting position of the pivot part 3, this is once above the table 5 and once outside the surface of the work table 5.
  • the clamping ring 31 can be seen from the outside, while the opening 32 now has a horizontal longitudinal axis and is therefore not directly visible.
  • the side 31 'of the swivel part 3 which is at the bottom according to FIG. 1 therefore lies in a vertical plane in FIG. 3 and faces the table support leg 21.
  • the screw head 27 ' is also outside the. Table top 51, so that favorable access to the screw head 27 'and a wide actuation area for a wrench are ensured.
  • FIG. 4 shows an application example of the clamping device I according to the invention together with the tool holder 4 and a tool 6 held by the latter, in the exemplary embodiment a vice.
  • the fixed part 2 of the device is in turn fastened to a work table 5 by means of the table support leg 21 and the clamping screw 23 '.
  • the clamping screw 27 forming the pivot axis 30 can also be seen in this figure.
  • the tool holder 4 is clamped with a cylindrical extension 41 into the swivel part 3 or its opening 31.
  • the tool holder 4 has a holder body 42 and a clamping ring 43 with a clamping screw 44.
  • a graduation scale directly opposite the swivel part 3, by means of which a desired angular position can be set by rotating the tool holder 4 about an axis of rotation 40 which corresponds to the central axis of the extension 41.
  • the vice 6 is clamped into the tool holder 4 or the opening 43 'of its clamping ring 43 with a suitable cylindrical extension 61, which in turn can be rotated about an axis of rotation 60 which corresponds to the longitudinal axis of the extension 61.
  • the Dreh greatest. Pivot axes 30, 40 and 60 in directions perpendicular to each other, so that the tool 6, which can also be a hand drill, for example, can be moved into almost any position and locked there.
