Description

Predmetom vynálezu Je technologická peleta nejmě pre upinanie rotačných obrobkov,The subject of the invention is a technological pellet, in particular for clamping rotary workpieces,

Sú známe technologická pelety ne upinanie rotačných obrobkov v ktorých ee obrobok upins mimo stroj e potom ako celok se upne na vřeteno stroja připadne medzi čeluste sklučovadla. Mejú vSak tú nevýhodu, že bud neumožňujú už počas obrábanla eliminovat pokles upínacej sily, alebo umožňujú zvěčšiť len kludovú uplnaclu silu.Technological pellets are known for clamping rotary workpieces in which the workpiece is upins outside the machine after it has been clamped on the machine spindle as a whole between the jaws of the chuck. However, they have the disadvantage that they either do not make it possible to eliminate the decrease of the clamping force during the machining operation or they only allow to increase the resting rest force.

Má to tú nevýhodu, že v jednom pripade mfiže nastat* nežiadúce uvolnenie obrobku a v druhom případe zas nežiedúca deformácia obrobku před začatim obrábanla v konečnom ddsledku změna geometrického tvaru obrobku po obrobeni.This has the disadvantage that, in one case, undesired workpiece release may occur, and in the other case undesirable deformation of the workpiece before machining has ultimately worked to change the geometrical shape of the workpiece after machining.

Uvedené nevýhody zmierňuje technologická paleta podle vynálezu ktorej podstatě spočiva v tom, že na spojovacom telese upínacích čelustí sú vytvořené opěrné plochy pre záběr s vonkajčimi plochami ovládacích telies upínacieho přípravku. Ďalěim význekom je, že spojovacie teleso je tvaru prstence a je z pružného materiálu.The above-mentioned disadvantages are alleviated by the technological pallet according to the invention, which essentially consists in that abutment surfaces are formed on the connecting body of the clamping jaws for engagement with the outer surfaces of the operating means of the clamping jig. A further drawback is that the connecting body is ring-shaped and made of a resilient material.

Technologickou paletou podía vynálezu sa dosiahne rýchle upnutie obrobku priamo na stroji pretože technologická paleta Je prispfisobená k priamemu upnutiu a dalej pri rotácii je pokles upínacej sily eliminovaný odstředivou silou ovládacích telies upínacieho přípravku.The technological pallet according to the invention achieves rapid clamping of the workpiece directly on the machine because the technological pallet is adapted to direct clamping and further in rotation the decrease in clamping force is eliminated by the centrifugal force of the clamping jig controls.

Na pripojenom výkrése je na obr.l znázorněná technologická paleta podía vynálezuFIG. 1 shows the technological pallet according to the invention

Technologická paleta podlá vynálezu sa skládá zo spojovaciaho telesa 10 tvaru kruhového prstenca na ktorom sú rovnoměrně po vnútornom obvode rozložená upinacie čeluste 40 spojené s nim spojovacími telesami 140 známým spésobom. Upnutia obrobku 50 v technologickej palata umožni deformovatalné spojovacia teleso 10, ktoré v priestore medzi čelusťami zo strany vonkajSieho obvodu sa radiálně dbstredivo deformuje, čim čeluste 40 sa radiálně od středu přesunů a umožnla vložit upínaný obrobok bu3 na upinacom pracovisku alebo priamo pri stroji.The technology pallet according to the invention consists of a ring-shaped connecting body 10 on which the clamping jaws 40 connected to the connecting bodies 140 in a known manner are distributed uniformly around the inner circumference. The clamping of the workpiece 50 in the process palatine allows a deformable connecting body 10 which radially deforms radially in the space between the jaws on the outer periphery side, thereby allowing the jaws 40 to move radially away from the center of movement and allow insertion of the clamped workpiece either.

Po uvolněni deformácie technologická paleta vytvoří s obrobkem Jeden celok, ktorý sa vkládá medzi ovládacie teleaá 20 upinacleho přípravku 30. Pri upínaní celku technologická palata. - obrobok je spojovacia teleso 10 vložené do upinacleho přípravku tak, aby jeho ovládacie oporná plocha 12 sa dostala do záběru s vonkajSou plochou 21 ovládacieho telesa 20. Radiálnym posunutím ovládacích talles 20 upinacleho přípravku 30 v smere Sipok b ako Je to vidieť na obrT3 nestává cez deformovatalné spojovacia teleso 10 dostředivé posunutie upínacích čelusti 40 v smere Sipok a a silové upnutle obrobku 50 uplnacou plochou 45 upínacích čelusti 40. ktoré aú dotlačené svojou doeadacou plochou 41 o vnútornú plochu 14 spojovaciaho telese 10. Uvolnenle celku technologická paleta - obrobok je převedené v opačnom smere Sipok a b.After releasing the deformation, the process pallet forms a unit with the workpiece, which is inserted between the control bodies 20 of the clamping device 30. When clamping the unit, the process pallet. the workpiece is the coupling body 10 inserted into the fixture so that its control abutment surface 12 engages the outer surface 21 of the control body 20. By radially moving the control talles 20 of the fixture 30 in the direction Sipok b as seen in FIG. deformable coupling body 10 centripetal displacement of the clamping jaws 40 in the direction of Sipok and and force clamping the workpiece 50 through the gripping surface 45 of the clamping jaws 40 which are pushed with their bearing surface 41 against the inner surface 14 of the coupling body 10. Sipok a b.

Technologická paleta podía vynálezu nájde uplatnenie v automatických výrobných systémech Použitie manipulátora alebo iného mechanizmu na vkladanie celku technologická paleta - obrobok do upinacleho přípravku, pričom chápač manipulátora zachytává vždy rovnaký priemer spojovaciaho telesa, zjednoduSi jeho riadiaci systém.The technological pallet according to the invention finds application in automatic manufacturing systems The use of a manipulator or other mechanism for inserting a whole technological pallet - workpiece into a fixture, wherein the manipulator's gripper always captures the same diameter of the connecting body, simplifies its control system.
