Definitions
- Marking the center of a workpiece end face has so far been realized by drawing two lines, one from each corner of the Guide the workpiece face to the diagonally opposite corner. At the The workpiece was then grained at the intersection of these two lines. To the the workpiece is then clamped. The centric Round timber was marked with the help of a centering angle.
- a device according to the preamble of claim 1 is known GB-A-142,381.
- the invention has for its object to develop a device that is easy to manufacture and with the turning parts on End faces can be centrally grained.
- the object is achieved in that four of the same Wall parts movably connected to one another by means of four hinge devices are that - viewed from the front - an isosceles parallelogram form, and centered on two opposite wall parts a bridge is movably mounted, a device for Carrying an iron (grains).
- the invention makes it possible in a single operation Grain the workpiece centrally. A previous marking is not necessary.
- the grains permanently resilient in the guide of the web held and thus enables marking with one hand, the other hand can hold the parallelogram. It is particularly advantageous To build wall parts from individual elements, so that for damaged or asymmetrically chamfered workpiece ends, insert the wall height can be enlarged by more elements. If you also run the footbridge for guiding the grain in the form of such an element, results a very inexpensive production of the entire component, since only one (Uniform) molded part is required.
- FIG. 1 shows the design of a marking device for turning parts a workpiece 7.
- the hinge-like connected wall parts 1,2,3,4 the workpiece 7 on the end face.
- the workpiece 7 touches during the marking process the web 5, which is designed as a central parallel, and is supported by an impact (arrow) on the striking device 6 marked centrally by the tip of the grain iron 9 presses into the workpiece.
- FIG. 2 shows a marking device in a front view, with a view of the wall part 2.
- the web 5 is 1.3 on two opposite wall parts movably mounted.
- the striking device 6 in unity with the grain iron 9 becomes in the geometric center of the parallelogram formed by the wall parts held.
- the return spring 8 represents the impact device 6 and that Grain iron 9 after graining back to its original position.
- FIG. 3 shows a marking device in a side view, with a view of the Wandte 1.
- the movable connection between the wall parts is through a toothing of the wall parts and a bolt 10 each realized.
- FIG. 4 shows the assembly of two wall parts 1, 2. It becomes clear that all wall parts are identical and interlock in the manner of a toothing.
- FIG. 5 shows the marking device with a view perpendicular to the impact device 6, the device being shifted to the parallelogram.
- FIG. 6 shows schematically the position of a workpiece end face that is to be grained centrally 71 with a rectangular shape. It is important to have two diagonally opposite corners of the workpiece at two corresponding opposite Corners of the parallelogram, so far from his square basic shape is sheared until this geometric condition is fulfilled.
- FIG. 7 shows schematically the position of a workpiece end face that is to be grained centrally 72 with a round shape. A centering is given here if each side of the parallelogram is in contact with the workpiece.
- Figures 8 to 14 show a particularly advantageous embodiment of the device, in which the wall parts 1 ', 2', 3 ', 4' each made up of several individual elements 11, 12, 13, 14, which are all identical in construction, just like the Bridge 5 '. These elements have recesses at their ends, which, seen from the longitudinal edge, extend over half the height and so one Allow elements to be interlocked. For this, elements are used during assembly Adjacent sides (e.g. 1 ', 2') each face each other mounted as illustrated in Fig. 11. Centering a workpiece with a rectangular 71 'or round cross section 72' is shown in FIGS. 13 and 14 shown for this embodiment and runs like that in Figures 6 and 7, procedures illustrated for the first embodiment.
- Adjacent sides e.g. 1 ', 2'
- Centering a workpiece with a rectangular 71 'or round cross section 72' is shown in FIGS. 13 and 14 shown for this embodiment and runs like that in Figures 6 and 7, procedures illustrated for the first embodiment.
- the elements are preferably made of plastic, but can also be made of metal or wood.
