Definitions

  • the invention relates to a transport and holding device for rod-shaped workpieces, in particular for hollow profiles, which can be fed to a machining center and machined therein.
  • the processing of profiles delivered in bars, which are to be subdivided and processed accordingly in order to cut the cut profile segments z. B. to assemble a window or door frame requires a lot of work and time.
  • the profiles must namely be clamped by means of workpiece clamping devices in the manner of a vice on a machine table provided with T-shaped grooves and / or hole patterns, with which these are to be fed to a machining center or a machine tool.
  • the clamping devices are to be mounted manually on the machine table and positioned in such a way that the profile can also be machined at the intended locations.
  • the object of the invention is therefore to provide a transport and holding device for rod-shaped workpieces, with which it is possible to make a workpiece, for. B. a hollow profile, a machining center, without having to make several reclampings in order to be able to machine the workpiece almost on all sides. Rather, a clamped workpiece should be subdivided and the separated profile segments should be able to be machined at any point, even on the end face, and work processes should not be impeded by clamping devices. These should be arranged briefly in such a way that the profile can be processed freely by the tools. Optimal processing without large waste and longer manual set-up times and the profiles being damaged should therefore be guaranteed. Furthermore, it should be possible to adapt to workpieces to be machined differently without difficulty.
  • a transport and holding device which is characterized by a movable on a stationary mounting rail Carriage and a large number of couplings that can be coupled to this, in which the workpiece is held by means of adjustable clamping jaws, and actuators for opening the clamping jaws and for loosening the connection between the carriage and the vice.
  • the vices should each consist of a stationary clamping jaw and a clamping jaw that can be adjusted perpendicularly to the slide by the force of a spring, which should be actuable individually and / or together by servo devices that can be acted upon by pressure medium against the force of the spring.
  • a collet and a servo device for actuating the adjustable jaws of the vices and / or two or more collets with a lateral spacing from one another and preferably mutually adjustable laterally next to the mounting rail, preferably opposite one another.
  • a servo device should be provided outside of the machining center next to the mounting rail, by means of which the clamping sticks coupled to the slide can be actuated together.
  • a transport and holding device for rod-shaped workpieces according to the invention in which a movable slide, a plurality of clamping sticks which can be coupled with this and also actuators associated therewith are provided, it is possible to insert a workpiece into these by opening all the necessary clamping sticks together and to be fed to the machining center by means of the slide, but since the vices can be decoupled from the slide and can also be opened individually, it is also possible with the help of the control of the machining center without difficulty and at short notice to separate separated profile segments and each of the vices onto the workpiece and / or let its parts act so that the workpiece or workpiece segments can be processed unhindered at the intended location.
  • the device shown schematically in FIGS. 1 and 2 and designated 1 serves for the transport of rod-shaped workpieces, for example a hollow profile 4, to a machining center 2 and for holding even during a machining process and essentially consists of a carriage which can be moved on a fixedly arranged rail 10 11, a large number of vices 21 and actuators for these in the form of servo devices 31, 41 and 51 which can be actuated by a pressure medium and are attached laterally next to the rail 10 Vices 21 for inserting the workpiece 4 are opened together, the servo device 41 is used to open one vise 21 at a time. And the two servo devices 51 can be used to release the connection between a vise 21 and the slide 11.
  • a support plate 24 provided with grooves 24 ' is held to be displaceable to a limited extent in its axial direction, in the grooves 24' of which the clamping jaws 23 can be used alternately depending on the width of the workpiece to be clamped.
  • the compression spring 29 acts on the support plate 24 via an intermediate piece 30.
  • the attachment piece 30 is firmly connected to the support plate 24 and passes through the tube 25, into which longitudinal slots 25 'are incorporated.
  • the clamping force of the compression spring 29 is thus transmitted to the support plate 24 and from this to the clamping jaws 23.
  • the pressure medium consisting of a hydraulic cylinder 42 with pistons inserted in these pistons is to be supplied so that the piston rod 43 on the intermediate piece 30, to which a roller 30 'is attached can act.
  • the vices 21 are detachably connected to the slide 11 by a clamp connection.
  • a guide rail 12 which has wedge surfaces 13 and 13 ', is fastened to it by means of screws 14, and a clamping piece 26 is attached to the pipe 25, which carries a further clamping piece 27 which can be pivoted about a bolt 28. Due to the force of a compression spring 29 'acting on the clamping piece 27 and supported on the clamping piece 26, the clamping piece 27 with the clamping surface 27' is pressed against the clamping piece 13, so that the vice 23 is carried along by the slide 11 when the slide 11 is moved.
  • the clamping connection between the clamping piece 21 and the slide 11 is released by means of the servo device 51 designed as a collet 52.
  • the piston rod 54 of a piston which can be acted upon by a pressure medium and acts on a cylinder 53 acts on the collet 52, by means of which the clamping lever 27 rotatably mounted on the bolt 28 can be pivoted and can thus be released from the clamping piece 13.
  • a workpiece 4 is to be machined in the machining center 2 by means of the tools inserted in a tool carrier 3, then first of all, by means of the servo device 31, which in the exemplary embodiment shown is designed as a plate 32 adjustable by a hydraulic cylinder 33 provided with a piston, are all separate to open vices 21 located outside the machining center 2.
  • the servo device 31 acts on the intermediate pieces 30, so that the clamping jaws 23 are displaced to the right against the force of the spring 29 and the workpiece 4 can be inserted.
  • the jaws 23 are on the Align the width of the workpiece 4.
  • the clamping jaws 23 are pressed against the workpiece 4 by the force of the compression spring 29.
  • the slide 11 is then fed to the tool carrier 3 in a controlled manner and the workpiece 4 is, for example, as shown in FIG. 2, divided into two tool segments 4 ′ and 4 ′′.
  • the workpiece segments 4 'and 4' 'must be separated. This is accomplished in such a way that with the help of the servo devices 41 and / or 51 arranged opposite one another in the machining center 2 and a controlled method of the slide 11, in which the connections between a vice 21 and the respective workpiece segment 4 'or 4 '' and between the vice 21 and the slide 10 are solved, the vices 21 are positioned accordingly with respect to the workpiece segments 4 'and 4' '.
  • the two servo devices 51 are to be arranged at such a distance from one another that at least the vices 21 acting on one of the workpiece segments 4 ', 4' 'can be actuated by the servo devices 51.
