VPENJALA ZA VPETJE OBDELOVANCEV OKROGLIH INCLAMP CLAMPS FOR CIRCULAR AND WORKERS
PRAVOKOTNIH OBLIKRECTANGULAR FORMS
Predmet izuma so vpenjala za vpetje obdelovancev okroglih in pravokotnih oblik pritrjenih na referenčne elemente različnih vpenjalnih sistemov. Izum spada v razred B 23H 7/26 mednarodne patentne klasifikacije.The object of the invention is clamps for mounting workpieces of circular and rectangular shapes attached to the reference elements of different clamping systems. The invention belongs to class B 23H 7/26 of the international patent classification.
io Tehnični problem, ki ga ta vpenjala rešujejo, je vpetje okroglih in pravokotnih obdelovancev z vpenjalom, kjer so naležne površine, ki določajo pozicijo obdelovanca in gibljivi del, ki omogoča vpetje obdelovanca na vpenjalu izdelanim iz enega kosa. Sodobne tehnologije omogočajo izdelavo takih vpenjal z relativno majhnimi stroški.io The technical problem that these fixtures solve is the clamping of circular and rectangular workpieces with a fixture, where there are contact surfaces that determine the position of the workpiece and a movable part that enables the workpiece to be fastened to the fixture made from a single piece. Modern technologies make it possible to produce such fasteners at relatively low cost.
is Uporaba teh vpenjal je predvidena predvsem za vpetje manjših elektrod na sodobnih napravah za potopno elektroerozijsko obdelavo z menjalci za avtomatsko menjavo elektrod. Za vpetje okroglih oblik obstojajo hidravlična vpenjala v katere lahko vpnemo le okrogla držala elektrod izdelane v dovolj ozkih tolerancah (n.pr. vpenjala sistema 3R izis The use of these fixtures is intended primarily for mounting smaller electrodes on modern submersible electro-erosion treatment devices with automatic electrode changeover gears. For clamping the circular shapes, there are hydraulic clamps into which only circular electrode holders made in sufficiently narrow tolerances can be clamped (eg 3R system clamps from
Švedske sistema Mini in vpenjala sistema Mecatool iz Švice sistema GPS 20 ). Za vpetje pravokotnih oblik obstoja rešitev proizvajalca EROVVA iz Švice z oznakami ER-010607, ER-032810 itd., ki omogočajo vpetje držal elektrod ali pa ustrezno obdelanih surovcev za izdelavo elektrod iz bakra ali grafita. Ta vpenjala lahko večkrat uporabimo. Pri uporabi menjalca elektrod je potrebno kupiti večjo količino vpenjal in s tem tudi velika vložena sredstva.Swedish Mini system and Mecatool fasteners from Switzerland GPS system 20). For mounting rectangular shapes, there are solutions from the EROVVA manufacturer in Switzerland with the markings ER-010607, ER-032810, etc., which allow the mounting of electrode holders or of appropriately machined workpieces for copper or graphite electrodes. These fixtures can be used repeatedly. When using an electrode changer, you need to buy a larger amount of fixtures and thus a large amount of money invested.
Izvedba vpenjal po izumu je veliko cenejša in ne bo presegala 15 do 20% cene predhodno omenjenih vpenjal. Tudi ta vpenjala lahko 5 večkrat uporabimo, vložena sredstva pa so zaradi nižje cene vpenjal temu primerno manjša.The implementation of the fixtures according to the invention is much cheaper and will not exceed 15 to 20% of the price of the previously mentioned fixtures. Also, these fixtures can be used 5 more times, and the invested funds are correspondingly smaller due to the lower price of fixtures.

It enables the right-to-right rectangular shape to be fastened. One edge on the rectangular shape is cut to the length of diagonal C with a maximum deviation of ± dC, depending on the size of the gap between the base work 1 and movable part 5. The clamp comprises a base part 1 in which a bore with four contact surfaces 6 ', 6, 7, 8. The contact surfaces 6', 6 and 7 are fixed and the support surface 8 is movable. When clamping the workpiece, insert the workpiece into the hole with the screw 4. Loosen the workpiece with the appropriate force, which is obtained by tightening the screw 4. The clamping force io is transmitted via circular springs 3 and beads 2 to the moving part55. Alternatives are also possible where the clamping force is transferred to the moving part from the screw 4 to the ball 2 to the moving part 5 or the embodiment where the force is transferred from the screw 4 directly to the moving part 5. The moving part 55 is connected to the base part 1 via one-sided bracket 55 '- 55. This is designed so that part 55' is connected to the base part 1, and part 55 rests on a pin 9, which is pressed into the base part 1 and allows movement of part of the carrier 55 in the longitudinal direction . The movement is limited by the size of the gap between the fixed part 1 and the movable part 5. The maximum movement is achieved when the cantilever 55 'rests on the surface 51' on the base part 51 and the tooth 55 on the surface 51 on the base part 1. screw 4 unscrew. The force caused by the deformation of the double-sided bracket 55 '55 moves the moving part 5 and the workpiece can be removed from the bore on the fixed part 1.
