Definitions

  • the invention relates to an insert tool according to the preamble of claim 1 such as in the US-A-2789402 disclosed.
  • the invention relates to an insert tool with an abrasive sheet and a support plate and with a hub having at least one recess, via which the hub can be tensioned on a driving flange of a grinding machine connected to a drive shaft.
  • the hub is formed by a separate component from the support plate. It can be achieved a particularly inexpensive and well stackable insert tool whose hub can be easily designed for a conventional entrainment device of a grinding machine with a nut and / or for a quick-release system.
  • the insert tool via at least one movable against a spring element latching element with a driving device of the grinding machine is operatively connected, which engages in an operating position of the insert tool and fixes the insert tool positively.
  • the locking element can fix the insert tool directly or indirectly via an additional component form-fitting manner, for example via a locking element coupled to the rotatable and / or axially displaceable locking lever or plunger, etc.
  • the locking element, the insert tool in different directions directly and / or indirectly positively fix, such as in the radial direction, in the axial direction and / or particularly advantageous in the circumferential direction.
  • the insert tool is fixed positively in a second direction by the positive locking of the insert tool with the locking element in a first direction, for example in the radial direction, the insert by a separate component from the locking element in a second direction, for example in the circumferential direction.
  • Is in the hub at least a first recess for a positive connection with the driving device in at least one circumferential direction and at least one second recess separated from the first recess for a positive connection in the axial direction can be achieved, which substantially advantageous can be executed just and without hooks. Hooking of the hubs during manufacture and storage can be avoided and good handling of the insert tool with its hubs can be made possible. Further, the components for securing the hub can be advantageously designed for their function, ie either on the fixation in the circumferential direction or on the fixation in the axial direction.
  • the hubs can easily be carried out advantageously with a closed center hole and it can be a low-vibration running of the insert tool allows. Furthermore, it can be achieved with a suitable choice of the diameter of the center hole, that the insert tools according to the invention can be attached via previously known fastening devices on conventional grinding machines, in particular via fastening devices, in which the insert tool with a clamping nut and a clamping flange on the drive shaft against a support surface positively in the axial direction and non-positively fixed in the circumferential direction.
  • At least one elongated hole is introduced into the hub, which has a wide area and at least a narrow area.
  • the hub can be easily stretched over the slot in the axial direction.
  • the hub can be used as a spring element, for example, by the hub is elastically deformed when moving the component in the slot.
  • the hub can be used to deflect a component against a spring element in the axial direction. Additional components, assembly costs and costs can be saved.
  • the hub has a deviating from the rotational symmetry contour, in particular outer contour, which is positively connected in the circumferential direction with a corresponding contour, in particular the inner contour of the support plate.
  • a torque can be transmitted from the hub advantageous by a positive connection to the support plate. Additional fasteners, for example to achieve a frictional connection, can be avoided or at least supported in their function and costs can be saved.
  • the hub can be mounted directly on the driving flange, whereby a particularly accurate positioning of the hub, the sanding sheet and the support plate to each other can be achieved. Furthermore, the hub can be accessed and fastened with short locking elements.
  • the hub may have various contours appearing reasonable to those skilled in the art for transmitting the torque by positive engagement, such as an oval or polygonal contour, etc., which may be formed in various areas of the hub.
  • the deviating from the rotational symmetry contour is formed on a pointing in the axial direction shaping of the hub, whereby a large transfer surface between the hub and the support plate and thus at a torque transmission over the transfer surface an advantageously small surface pressure can be achieved.
  • the hub can be stacked particularly advantageously and centering of the hub in the support plate can be achieved.
  • the hub may be formed of various materials that appear appropriate to those skilled in the art, for example, a high-strength plastic, etc.
  • the hub is formed by a deep-drawn sheet metal part, which is particularly inexpensive and easy to produce.
  • a bearing surface of the hub and a support surface the support plate in a common plane, a corresponding bearing surface of a flange can be shared and a common reference plane can be achieved for the support plate and the hub. Additional components can be saved and it can be advantageously achieved an exact assignment of the support plate and the hub to each other.
  • the hub is formed by a separate component from the abrasive sheet, whereby the sheet metal hub can be stored to save space, inexpensive to produce and in particular easy to reuse.
  • the hub has a contour deviating from the rotational symmetry in the region of its abutment on the abrasive sheet, which can be positively connected in the peripheral direction with a corresponding contour of the abrasive sheet, a torque can advantageously be transmitted in a form-fitting manner via the contours. Additional fasteners for transmitting torque from the hub to the abrasive sheet may be functionally supported or possibly completely replaced.
  • the hub can be connected to the sanding sheet via all frictional, positive and / or material-locking connections that appear appropriate to the person skilled in the art, for example via an adhesive connection, rivet connection, clamping connection, etc.
  • the hub can be simply, safely and without tools connected to the sanding sheet.
  • a small axial force between the hub and the abrasive sheet large holding forces in the circumferential direction can be achieved.
  • the axial force can advantageously be generated by the assembly process of the insert tool on the grinding machine.
  • the claws may be formed by additional components attached to the hub.
  • the claws are integrally formed on the hub, for example in a punching operation. The production of the claws can thereby be advantageously incorporated into the manufacturing process of the hub and additional components can be avoided.
