Abstract
Description
Vynález ее týká ůchopové hlavice, zejména pro průmyblovérobáty.The invention also relates to a grip head, particularly for industrial articles.
Ůchopové hlavice průmyslových robotů jsou opatřeny čelistmi, které se při uchopení břemene sevřou a po vykonání příslušné operace ae rozevřou a břemeno uvolní·The gripper heads of industrial robots are equipped with jaws which grip when the load is gripped and open and release the load when the operation is performed.
U stávajících konstrukcí jsou čelisti ůchopové hlavice ovládány hydraulicky nebo pneumaticky, i když ostatní mechanismy průmyslového robota jsou opatřeny pohonem elektrickým. To vyžaduje přivádění tlakového oleje nebo tlakového vzduchu do pohybového ústrojí ůchopové hlavice. To je spojeno s potřebou složitých přídavných konstrukcí, a problémy utěsňování a podobně. ltevíc jsou tyto mechanismy hlučné, zejména pneumatické.In existing designs, the gripper jaws are operated hydraulically or pneumatically, although other industrial robot mechanisms are electrically driven. This requires the supply of pressurized oil or pressurized air to the gripper head. This is associated with the need for complex add-on structures, and sealing problems and the like. Moreover, these mechanisms are noisy, especially pneumatic.
Výěe uvedené nevýhody odstraňuje ůchopové hlavice podle vynálezu, jejíž podstata spočívá v tom, že sestává z elektromotoru, na jehož statoru jsou upraveny nosiče, v nichž jsou kloubovitě uchycena výkyvná ramena, opatřená ůchopovými čelistmi, přičemž hřídel rotoru elektromotoru je opatřen Šroubem, na nBmž je upravena matice, opatřená čepy auvně uloženými ve vybráních ve výkyvných ramenech.The aforementioned disadvantages are eliminated by the gripping heads according to the invention, which consists of an electric motor, on whose stator there are supports, in which the pivoting arms provided with gripping jaws are articulated, the rotor shaft of the electric motor being provided with a screw. provided with a nut provided with pins and slidingly mounted in recesses in the swinging arms.
fteSením podle vynálezu ae dosahuje velmi jednoduchá konstrukce, jednotného pohonu průmyslového robota pouze elektrickou energií a značného snížení hlučnosti.With the invention and very simple design, the uniform drive of the industrial robot is only achieved by electrical energy and greatly reduced noise.
Příklad provedení ůchopové hlavice podle vynálezu je znázorněn v axiálním řasu na připojeném obrázku.An exemplary embodiment of the grip head according to the invention is shown in axial algae in the attached figure.
№ statoru 4 elektromotorů 2» opatřeném kostrou б в chladicími žebry, jsou nosiče Z, v nichž jsou kloubovitě uchycena výkyvná ramena 2» opatřená na konci ůchopovými čelistmi 1-3; Hřídel 1 rotoru 2 elektromotoru 2 J® opatřen a ním souosým pohybovým Šroubem 2, na němž je upravena matice 10, která je spojena s výkyvnými rameny 2· Toto spojení jo provedeno vybráním 12 ve výkyvném rameni 2 β do něho zasahujícím čepem 11. upraveným na obvodu matice 10. která může být provedena jako kotouč o velkém průměru nebo jako kotouč s malým průměrem, opatřeným rameny 2· J®^ J® tomu v daném případě.№ of the stator 4 of the electric motors 2 »provided with a skeleton б in the cooling fins, the carriers Z in which the pivoting arms 2» are articulated are provided with gripping jaws 1-3 at the end; The shaft 1 of the rotor 2 of the electric motor 2 is provided with a coaxial movement screw 2 on which a nut 10 is connected which is connected to the swinging arms 2. This connection is effected by recess 12 in the swinging arm 2 β. the circumference of the nut 10, which may be in the form of a large-diameter disk or a small-diameter disk provided with the arms 20 '.
Ц· provedení naznačeného na výkrese jsou výkyvná ramena 2 uspořádána v rovině procházející osou rotace hřídele 1 rotoru 2 elektromotoru g, avšak mohou být uspořádána i v rovině neprocházející osou rotace hřídele 1. Dráha matice 10 Je vymezena na obou stranách tlumicími prvky 15, v daném případě talířovými pružinami. Tím je zajištěno bezrázové ukončení pohybu matice 10 v obou směreoh. Pohybový Šroub 2 je dále na svém volném konci opatřen narážkou 14. Pohybový Šroub 2 je s výhodou proveden jako kuličkový Šroub a v celku a hřídelem X rotoru 2 elektomotoru 2· Pomocí nosných čepů 8 je ůchopové hlavice nesena mechanickým ramenem průmyslového robota.Of the embodiment shown in the drawing, the swinging arms 2 are arranged in a plane passing through the axis of rotation of the shaft 1 of the rotor 2 of the electric motor g, but they can also be arranged in a plane not passing through the axis of rotation of the shaft. in case of disc springs. This ensures that the movement of the nut 10 in both directions is impactlessly terminated. The motion screw 2 is further provided with a stop 14 at its free end. The motion screw 2 is preferably a ball screw and in the whole and shaft X of the rotor 2 of the electric motor 2.
Připojením elektromotoru £ na sil ae matice 10 vysune směrem od elektromotoru 2 ® ůchopové čelisti 13 se sevřou. Při opačném chodu elektromotoru 2 ®® matice přesune směrem к elektromotoru 2 8 ůchopové čelisti 13 se rozevřou. Elektromotor 2 J® a výhodou vytvořen Jako dorazový motor, který je dimenzován tak, že Jo pod proudem i po přesunu matice 10 na konec její dráhy, takže samosvdmost pohybového Šroubu není podmínkou. Toto řešení je zvláší výho213 ·17 dní u kuličkového Šroubu, který má vysokou účinnost, ale není samoavorný. Při použití nereálního pohybového Šroubu 2 Je možno využít Jeho eamosvomoati pro držení břemene i když Je proud do elektromotoru £ vypnut. V případi, že Je potřeba zajibtit držení břemene při vypnutém elektromotoru 2 a nesamosvorném pohybovém Šroubu 2, použijí ae pružiny známým způsobem.By attaching the electric motor 6 to the force and the nut 10 extends away from the electric motor 2, the gripping jaws 13 are clamped. In reverse operation of the electric motor 2 ®, the nut moves towards the electric motor 2 8 the gripping jaws 13 open. The electric motor 21 is preferably designed as a stopper motor, which is dimensioned so that it is energized even after the nut 10 has been moved to the end of its path, so that the self-rigidity of the movement screw is not a condition. This solution is especially advantageous for a 13 · 17 day ball screw that has high efficiency but is not self-healing. By using an unrealistic motion screw 2, its eamosvomoati can be used to hold the load even when the current to the electric motor 6 is switched off. If it is necessary to ensure that the load is held when the electric motor 2 and the self-locking movement screw 2 are switched off, they will use the springs in a known manner.
