  • the invention relates to a tool clamping device, which is releasably displaceable outside the tool base plate on a machine tool table or on a press ram, each of which is provided with holding grooves, and according to the desired position of the tool by means of the between the bearing.
  • foot of the clamping device and the machine tool table or plunger provided connecting means, after the gradual possible presetting of the clamping height, according to the given clamping dimension of the tool clamping edge can be fixed by hydraulic or pneumatic means in a predetermined position.
  • Section 2 describes the changeover process, which is essentially determined by the tool removal, the press setting, the tool installation and the control of tools and the press setting.
  • Section 3 describes the aids for the conventional retrofitting process and here in particular the clamping aids, whereby the usual mechanical clamping elements are shown in Figure 2.
  • Figure 3 shows an overview of the clamping elements, e.g. containing clamping elements, which are arranged outside the tool base plate, the solution numbers 2 to 5 contain fully hydraulic systems, the solutions 6 to 8 show the maintenance of an elastic but hydraulically releasable clamping force and the proposed solution 9 provides a hydraulic system with mechanical clamps.
  • a disadvantage of the systems mentioned is that the different heights of the tool clamping edge can only be taken into account by means of stair trestles which, with different settings, require a different distance between the tool clamping device and the tool clamping edge.
  • Each specific height setting results in a specific distance between the tool clamping device and the tool, which further leads to a different stress on the clamping arms or clamping claws at different distances.
  • a tool clamping device of the type described at the outset which, with a clamping height presetting integrated with the clamping device, Regardless of the thickness of the tool clamping edge, i.e. the clamping height, it is easy and quick to maintain a consistently short distance from the clamping edge with the quickest setting or conversion to the clamping height to be taken into account without intermediate elements such as clamping irons, clamping claws or the like.
  • the solution according to the invention provides that the bearing foot in the delimitation area to the tool clamping edge is provided with a turret head which can be rotated about a bolt, over the circumference or partial circumference of which is formed evenly distributed clamping lugs, each increasing by an equal height, which are directed towards the tool clamping edge Adjustment - fixed by means of locking pins which are resiliently arranged in the turret and reach into the top level of the bearing foot - reach over the tool clamping edge,
  • the intermediate level of the bearing base is connected to a pressure cylinder, the piston rod of which is delimited by a head forming a support point, and that the uppermost level of the bearing base is connected to a fork head, which forms the bearing for a pivot pin and a lever rocker carried by it, these on the one hand the bearing head of the piston rod of the pressure cylinder and, on the other hand, a limiting part of the turret head which likewise forms a support point.
  • the power flow leads from the pressure cylinder over the head of the piston rod forming a support point via a lever rocker to the upper limiting part of the turret.
  • the lever rocker is mounted on a swivel shaft in a fork head arranged between the pressure cylinder and the turret and connected to the bearing foot.
  • the connecting means provided between the bearing base of the clamping device and the machine tool table have at least one T-slot nut which is displaceably arranged in a T-shaped holding groove in the machine tool table or the press ram and at least one in a T-shaped holding groove of the Provide the bearing foot of the clamping device arranged second T-slot nut, the T-slot nuts are connected by a threaded bolt.
  • This design enables, with a sufficient length of the T-shaped holding groove introduced into the bearing base, even with a somewhat unfavorable position of the holding groove proposed in the tool table to the tool clamping edge, for a given tool position, over a wide range, the practically direct contact of the tool clamping device in the tool clamping edge.
  • the retaining groove in the bearing base will be defined in more detail later.
  • the bearing foot directed against its limiting area pointing towards the tool clamping edge, partially receives a support in the edge area, perpendicular to the direction of the lever rocker, around which the bearing foot can be swiveled on the tension side by a small amount, up to about 1 mm, the support being a flattened round rod.
  • the partial length of the lever rocker facing the impression cylinder be made longer and the partial length of the lever rocker facing the turret shorter.
  • the mounting of the pivot pin of the lever rocker in the fork head is adjustable, and that the length of the lever rocker takes into account the extent of the predetermined adjustment possibility.
  • an inadequate high position of the uppermost clamping nose in relation to the thickness of the clamping rim can be taken into account by inserting a plug-in shoe which can be pushed in, and that ball grids are provided in the plug-in shoe, which correspond to recesses provided for engagement of the balls in the bearing base, the The thickness of the plug-in shoes is adapted to the pitch of the bearing foot in its uppermost setting and the plug-in shoe is provided with a T-piece corresponding to the groove of the bearing foot.
  • any clamping dimension can be set by simply plugging together without using auxiliary tools.
  • the T-shaped holding groove arranged in the bearing base has such a length that the here. introduced T-slot nut, which is connected to the T-slot nut arranged in the machine tool table or the ram, can be displaced in half its length up to the vertical axis line of the Schwenli bolt.
  • the bearing base 1 is provided in its delimitation area 1.5 directed towards the tool clamping edge 16 with a T.- shaped holding groove 1.8, the dimensions and shape of which correspond to the T-slot nut 10 to be accommodated by it.
  • the border area 1.6 runs in the opposite direction to the border area 1.5, in which the support 11 is arranged parallel to the border area 1.5 and to the border area 1.6.
  • the support 11 enables the swiveling stroke, caused by the reaction force from the clamping force, of up to approximately 1 mm at the boundary region 1.5 of the bearing foot 1 facing the tool clamping edge 16.
  • a groove 15.1 is arranged in the machine tool table 15, which in turn receives the T-slot nut 8.
  • T-slot nut 10 and T-slot nut 8 are clamped to one another by the connecting bolt 9, i.e. the bearing base 1 is fixed on the machine tool table 15.
  • a bolt 3 which is fixed in the uppermost level 1.2 of the bearing base 1, for receiving the turret head 2 is rotatably arranged.
  • the revolver head 2 is provided over its circumference with uniformly distributed clamping lugs 2.1, each rising by an equal height.
  • two resilient locking pins 4 are provided in the upper level of the bearing base 1 in recesses 1.3.
  • the central passage through the turret 2 designed in accordance with the bolt 3 is closed at the top by a limiting part 2.2 forming a support point.
  • a fork head 1.4 is firmly connected to the bearing base 1.
  • the fork head 1.4 forms the pivot bearing for the pivot pin 7 carrying the lever rocker 6.
