Definitions

  • the present invention relates to a dividing and parallel drawing angle, consisting of two abutment legs including a right angle, connected at one end to one another, and a holding leg fastened between them in their cutting area, one longitudinal edge of which is the bisector of the included right angle.
  • This centering angle is already known as a so-called centering angle.
  • This centering angle is applied to the circumference of a circular area with both contact legs, so that the center point of the circular area can be torn by means of the central leg.
  • this known centering angle it is not possible to make arbitrary circular divisions on the round body and to draw or record any polygons, be they regular or irregular, on the surface of the round body.
  • a tell-teller, a parallel height ripper and a marking plate have been used so far, but their joint handling is relatively difficult and time-consuming.
  • these three parts are bulky and difficult to transport. In addition, they require considerable manufacturing costs.
  • the object of the present invention is to improve an angle device according to the prior art in such a way that any division and any polygon can be easily and quickly marked on the circular surface of a round body.
  • the angle device according to the invention should also be distinguished by a relatively low weight and low production costs.
  • an angled frame forming a right angle is arranged with its one frame leg on the middle leg, and a stop is slidably attached to this frame leg, the stop surface of which can be placed against the workpiece to be torn on the opposite side of the contact leg perpendicular to the longitudinal bisecting edge of the middle leg is standing, and the two frame legs are connected to each other by a leg forming at least a quarter-circle arc and there are preferably adjustment scales on the middle leg, the frame legs and the arcuate leg. It is advantageous if the two frame legs are of the same length.
  • a degree pointer is arranged displaceably perpendicularly to the quarter-circle-shaped leg.
  • the radius of the workpiece to be scribed is set on the leg of the angular frame parallel to the center leg. With this stop adjusted in this way, the angular frame is then shifted until it lies against the workpiece with the stop.
  • the degree pointer points exactly to the center of the workpiece, so that it can be marked easily, and with the help of one on the degree scale on the quarter-circle leg and second nonies on the degree indicator, any angle can be set on the quarter-circle leg of the angle frame and be scribed on the workpiece.
  • the angle set in each case can be added by rotating the entire angle device and thus any division and any polygon be scribed on the workpiece.
  • the parallel bar provided according to the invention serves to mark out squares or rectangles or to connect the intersections of polygons, be they regular, irregular or also to mark tendons and the like.
  • a centering and dividing angle which represents an easy-to-use tool in terms of its construction and, above all, its weight, and which can be used in a mobile manner, i.e. it can be used and used quickly anywhere.
  • This is particularly advantageous, for example, for workpieces that are not themselves transportable, either because of their weight or because they are firmly connected to other components.
  • a centering and dividing angle according to the invention consists of two stop legs 1, 2 which enclose a right angle and are connected at one end to the other forms.
  • the entire centering and dividing angle is stiffened by a cross bar 6, which is connected to one contact leg 1 and the middle leg 3.
  • a handle 7 is formed with which the centering and dividing angle can be handled.
  • the handle 7 can be made of plastic, for example, and is, for example, screw-like on the outside side of the system leg attached.
  • an angled frame 8 enclosing a right angle with a frame leg 9 is arranged to be longitudinally displaceable on the middle leg 3.
  • the frame leg 9 on the middle leg 3 has, for example at its two ends, transverse webs 11 which laterally enclose the middle leg with their web ends and are advantageously held in grooves in the middle leg in the form of a dovetail-shaped guide.
  • a grip part 11a is provided with a locking screw 12, with which the position of the entire angular frame on the center leg 3 can be fixed in the desired position.
  • the free ends of the frame legs 9, 10 of the angular frame 8 are connected to one another at the ends by an arcuate leg 14, which in the example shown is a quarter-circle arc.
  • a degree pointer 16 is displaceably arranged on the arcuate leg 14 by means of a guide part 17.
  • a stop body 21 is slidably arranged on the frame leg 9 of the angle frame 8 parallel to the center leg 3.
  • This stop body 21 consists of a guide part 22 and a stop section 23 perpendicular to the guide part, which is displaced such that the body 38 to be torn is enclosed between this stop and the two contact legs 1 and 2.
  • the stop section 23 is advantageously detachably attached to the guide part 22.
  • the guide part 22 is guided on the frame leg 9 in the same longitudinal guide grooves.
  • the stop body 21 can be fixed in any position on the frame leg 9 of the angular frame.
  • the entire angular frame together with the stop body on the middle leg 3 can then be displaced in the longitudinal direction.
  • the centering and dividing angle according to the invention also has a parallel bar 26.
  • This parallel bar is displaceably arranged at one end by means of a guide part 27 on the contact leg 2.
  • the guide part 27 is guided on the contact leg 2 in a manner known per se by means of T-shaped guide grooves which engage in the projections formed on the guide part 27.
  • the guide part 27 can be fixed on the contact leg 2 by means of a locking screw 28.
  • the contact leg 2, which serves to guide the parallel bar 26 is expediently longer than the contact leg 1.
  • a handle 29 is formed on the guide part , advantageously made of plastic, with which an easier handling of the guide part is achieved.
  • the individual parts of the centering and dividing angle according to the invention have different scales.
  • a continuous scale 31 is provided on the middle leg, this scale 31 has a millimeter graduation.
  • the two frame legs 9, 10 also have scales 32, 33, which expediently have a millimeter graduation.
  • the scales 32, 33 are not arranged on the frame legs in such a way that the longitudinal edge 4 of the middle leg coincides with the start of the scale 32 and the inner edge 34 of the frame leg 10 coincides with the start of the scale 33.
  • a scale 35 is preferably also provided on the parallel bar 26 , which has a millimeter division.
  • the contact leg 2 also has a scale. If the guide part 27 is shifted on the scale by 10 mm, the guide part 27 actually travels a distance of 14.14 mm on the contact leg 2, but the distance between the middle leg 3 and the parallel bar 26 changes only by 10 mm.
  • the operation of the centering and dividing angle according to the invention shown in FIG. 1 is now as follows: First, the radius of a workpiece 38 to be machined, which is shown in broken lines, is set with the stop body 21 on the scale 33 of the frame leg 9, and by means of the locking screw 24, the stop body 21 is clamped against vibration. Then the entire angular frame 8 with the stop body 21 is moved to the stop of its stop section 23 on the workpiece and fixed with the locking screw 12 also vibration-proof.
  • the centering and dividing angle according to the invention is thus also fixed on the workpiece 38 to be marked and includes this, but it can easily be rotated 360 ° and more around the workpiece.
  • the degree pointer 16 is now aligned and points precisely to the center of the workpiece 38, which can thus be easily torn.
  • any angle can be set and marked with a scriber on the workpiece.
  • the edge 34 of the frame leg 10 forms the second center line to the workpiece at an angle of 90 ° to the longitudinal edge 4, the angle set with the degree pointer can be added as often as desired by rotating the entire angle and thus any division and any polygon on the Workpiece to be scribed.
  • the parallel bar 26 serves to mark out squares or rectangles or to connect the intersections of polygons, be they regular or irregular or else for Marking of tendons, secants and tangents or the like.
  • the used distance between the parallel bar and the middle leg is set on the scale of the contact leg 2 with the guide part 27. Then the parallel bar is fixed with a vibration-proof screw, and now the desired line on the workpiece can be marked, for example with the help of a scriber.
  • the exemplary embodiment shown therein differs from that according to FIG. 1 in that, on the one hand, the adjustment of the angular frame via the handle part 11a and, on the other hand, the parallel cable strip are designed differently.
  • An adjustment body 42 which acts on the handle part 41 of the angle frame 8 by means of an adjustment pin 43, is used for fine adjustment of the position of the angle frame 8.
  • the distance between the two parts 41, 42 can be adjusted via the pin 43 by means of an adjusting wheel 44. Both parts can be fixed by means of locking screws 45, 46.
  • Another difference is in the design of the parallel bar 50. In the example shown, this consists of two scale carriers 52 formed parallel to one another on a guide part 51.
  • the scale carriers 52 are connected at their free ends via a web 54 for reasons of stability.
  • This embodiment has the advantage that, due to the fixed distance between the two scale carriers 52, several parallel lines can be drawn simultaneously.
  • the scale present on the scale carriers 52 is expediently again a millimeter scale 55.
  • Flg. 3 shows a further embodiment of a centering and pitch angle according to the invention.
  • the main difference to the embodiment according to FIG. 1 consists in the different guidance of the parallel bar 60.
  • This parallel bar 60 is slidably attached to a bar 61 running perpendicular to it, which is guided on the frame leg 10 perpendicular to the central leg 3 of the angle frame 8 .
  • the frame leg 10 has a guide part 62 fastened to it, in which the vertical bar 61 is dovetailed in grooves.
  • the vertical bar 61 expediently has a scale so that the distance to the middle leg 3 can be easily adjusted.
  • the design of the handle part 63 this corresponds in the form shown to the handle part 11 a according to FIG. 1.
  • stop part 21 there is no stop part 21, as shown in FIG. 1, but such a stop part is also present in the embodiments of FIGS. 2 and 3.
