Definitions

  • the invention relates to a tool clamping device, the bearing base according to the intended position of the clamping edge of the tool a machine tool table provided with holding grooves or a press ram each releasing or. slidably connected and after presetting the clamping height of the device, according to the thickness of the clamping edge of the tool, this can be fixed by hydraulic or pneumatic means.
  • 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 conversion 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, including 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 edge of the tool can only be taken into account by means of stair racks which, with different settings, require a different distance between the tool clamping device and the tool clamping edge. (See picture 2, top left and bottom right) This also applies to the possible integration of clamping bolts and stair brackets, i.e. with pivoting fixation of the clamping bolt in or on the stair trestle.
  • 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 in the introduction which - with a clamping height presetting integrated with the clamping device - regardless of the thickness of the tool clamping edge, i.e. of the clamping height, the maintenance of a consistently small distance to the clamping edge with the fastest setting or conversion to the clamping height to be taken into account without intermediate links, such as clamping arms, clamping claws or the like, enables in a simple and quick manner.
  • the solution according to the invention provides that the bearing foot is provided in a boundary area to the tool clamping edge with a turret which can be rotated about a pin fixed in the bearing foot, over the circumference or partial circumference of which the evenly spaced clamping lugs are formed, which are formed in the in each case directed towards the tool clamping edge - fixed by locking pins arranged in the turret head and engaging in a surface of the bearing foot - over the tool clamping edge that a pressure cylinder is attached to the bearing foot on the side of the turret head opposite the delimitation area, the piston rod of which is formed by a head forming a support point is delimited that a fork head is connected to the bearing foot between the turret and the pressure cylinder, which forms the bearing for a pivot pin and a lever rocker carried by it, this on the one hand the head of the piston rod of the pressure cylinder and on the other hand rests on a limiting part of the turret, which also 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
  • the T-nuts are connected by a threaded bolt.
  • This design allows, with a sufficient length of the T-shaped introduced into the bearing base. Holding groove, even in the case of a somewhat unfavorable position of the holding groove proposed in the tool table in relation to the tool clamping edge, for a given tool position, the practically direct contact of the tool clamping device in the tool clamping edge over a wide range.
  • the retaining groove in the bearing base will be defined in more detail later.
  • the bearing foot directed towards its limiting area pointing towards the tool clamping edge, in the edge area, perpendicular to the direction of the lever rocker, partially receives a support by which the bearing foot on the tension side, by a small lifting dimension, up to can be pivoted to about 1 mm, the support being a flattened round rod.
  • the partial length of the lever rocker facing the pressure cylinder be made longer and the partial length of the lever rocker facing the turret shorter. Irrespective of this, it can be provided that 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.
  • a high position of the clamping lug which is not sufficient in relation to the thickness of the clamping edge, can be taken into account by arranging a stretching shoe between the bearing foot and the machine tool table or ram, and that spring-loaded ball grids are provided in the plug-in shoe, which are used for engagement of the balls recesses provided in the bearing base correspond, the thickness of the plug-in shoes being adapted to the pitch of the bearing base in its uppermost setting and the plug-in shoe being provided with a T-piece corresponding to the groove of the bearing base.
  • 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 T-slot nut introduced here corresponds to the T-slot nut arranged in the machine tool table or the ram is connected, is displaceable in its half length up to the vertical axis line of the pivot pin.
  • the bearing base 1 is provided in its delimitation area 1.5 facing the tool clamping edge 16 with a T-shaped holding groove 1.8, the dimensions and shape of which correspond to the T-nut 10 to be received 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.
  • 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 surface 1.2 of the bearing foot 1 in recesses 1.3.
