Definitions

  • the invention relates to a clamping tool according to the preamble of claim 1.
  • the US 1,452,753 also describes a screw clamp with a fixed bracket, a slide rail attached to it and a slide bracket sliding on the slide rail.
  • a slide bracket sliding on the slide rail.
  • locking balls which, in the non-locked position, are intended to prevent the slide bracket from slipping relative to the slide rail and which, when the screw clamp is jammed, are pressed into a recess in the narrow side of the slide rail due to the slide bracket tipping over the slide rail.
  • the object of the invention is to provide measures to prevent the sliding bracket of the clamping tool from slipping in the released position, that is to say when the workpiece is not clamped on the slide rail.
  • a locking body is assigned to the slide bracket, which can be elastically deflected and protrudes into the eye.
  • the elastically evasive locking body works independently of the tilting of the slide bracket on the slide rail with a locking profile of the slide rail.
  • the latching body interacts with the latching profiling of the slide rail in such a way that the anti-slip device already acts securely before a workpiece is clamped. For example, if the tensioning tool is attached to a preset position of the sliding bracket, this cannot lose its secure position or slip again, for example due to vibration.
  • the arrangement of an elastically evasible locking body in the eye of the slide bracket provides a non-gravity anti-slip device.
  • the locking body is arranged in such a way that it is always elastically loaded in the direction of the locking profile of the slide rail.
  • the anti-slip device can only be lifted in concrete.
  • the locking body is a sprung ball.
  • the spring always urges the ball in the direction of the locking profile, which ensures that the slide bracket is securely attached to the slide rail in every locking position.
  • the locking profiles are spaced apart from each other in the rail extension direction. The latter are preferably adapted to the cross section of the ball.
  • the notches are on the broad side of the rail.
  • the locking troughs on both broad sides of the rail for interaction with two locking bodies protruding into the eye of the sliding bracket.
  • the design is advantageously selected such that the latching body is embedded approximately in the middle of the broad side wall of the eye.
  • the locking body for example in the form of a spring-loaded ball, acts centrally on the slide rail having the locking profile. It is essential that the locking body acts functionally independent of the jamming of the slide bracket on the slide rail.
  • a screw clamp 1 consisting of a steel slide rail 2 with a fixed bracket 3, for example made of malleable cast iron.
  • the fixed bracket 3 is firmly connected at one end to the slide rail 2 and forms at the other end a clamping surface 4 on the underside.
  • a slide bracket 5 is also slidably arranged on the slide rail 2, the slide rail 2 passing through the slide bracket 5 in the region of its eye 6.
  • the slide bracket 5 carries a tensioning element 7, which is provided with a thread, for example a trapezoidal thread
  • rotary handle 9 for the axial displacement of the clamping element 7.
  • the counter clamping surface 8 can be clamped in the direction of the clamping surface 4 for clamping a workpiece.
  • the screw clamp 1 is provided with an anti-slip device for the slide bracket 5 relative to the slide rail 2.
  • the slide rail 2 is provided with a latching profile 10, which in the exemplary embodiment shown is in the form of latching troughs 11 which are evenly spaced apart from one another in the direction of the rail extension.
  • the latter are arranged centrally on the broad side 12 of the rail and cooperate with a locking body 13 of the slide bracket 5.
  • this latching body 13 is a spring-loaded ball 14, which is embedded approximately in the middle of a broad side wall 15 of the eye 6 in a through hole 16 of the slide bracket 5.
  • this ball 14 is caulked such that a partial section of the ball 14 can emerge from the bore 16 into the region of the eye 6.
  • a compression spring 17 is arranged in the bore 16, which is supported at one end against the ball 14 and at the other end against a, for example, caulked shoulder of the bore 16.
  • the ball 14 forming the latching body 13 can accordingly be deflected inwards, ie in the direction of the bore 16, and at the same time secured against falling out by the caulking.
  • the locking troughs 11 forming the locking profile 10 are evenly spaced from one another in the direction of the rail extension, a distance between two locking troughs 11 being in the millimeter range, for example 3 to 5 mm.
  • the cross section of each recess 11 is preferably adapted to that of the ball 14.
  • the anti-slip device consisting essentially of locking body 13 and locking profile 10, ensures that the sliding bracket 5 is fixed on the sliding rail 2 regardless of the position of the clamping tool.
  • This preset position of the slide bracket 5 can only be changed in a way that is emphasized by shifting the slide bracket 5 by hand along the slide rail 2.
  • the detent body 13 or the ball 14 can dodge and always finds the next detent step spring-assisted.
  • this anti-slip device cannot be canceled by vibrations or careless handling.
  • the screw clamp 1 according to the invention can be securely brought into the workpiece to be clamped in the preset position of the slide bracket 5 without the preset span between the slide bracket 5 and the fixed bracket 3 changing.
  • the anti-slip device according to the invention is formed on an all-steel screw clamp 1, the slide rail 2 and the fixed bracket 3 being made in one piece, for example from a drawn bright steel.
  • the slide rail 2 has locking troughs 11 which form a locking profile 10 and which are in the form of a recess a ball 14 formed locking body 13 of the slide bracket 5 cooperate to form the anti-slip.
