Description

Vynález sa týká predpátého prizmatického valivého vedenia pre zváracie automaty, pre priamočiary pohyb vodiaceho telesa s obojstrannou prizmou voči nosnému telesu, pomocou motorického alebo ručného pohonu.The invention relates to a prestressed prismatic rolling guide for automatic welding machines, for the linear movement of a guide body with double-sided prism with respect to the support body, by means of a motor or manual drive.

Účelom vynálezu je zabezpečit’ bezvólové vedenie, nízké odpory pri přestavovaní, odolnost voči prašnému prostrediu, citlivé a přesné prestavovanie vodiaceho telesa Horáka na zváracích automatoch využívajúcich motorické, alebo ručné ustavovanie horáka voči zvarovému spojů.The purpose of the invention is to provide a free-of-charge guide, low adjustment resistance, resistance to dust, sensitive and precise adjustment of the torch guide on automatic or manual alignment of the torch to the welded joints.

Predpáté prizmatické valivé vedenie pre zváracie automaty sa vyznačuje tým, že pozostáva z dvoch kladiek pevne uložených na nosnom telese pre vedenie obojstrannej prizmy z jednej strany a z dvoch letmo uložených kladiek umiestnených na koncoch listovej pružiny pre vedenie obojstrannej prizmy z druhej strany. Listová pružina jp upevněná na konzolu rozoberatelne spojená s nosným telesom a predpínacou skrutkou pre dosadnuí tie letmo uložených kladiek do obojstrannej prizmy.The fifth prismatic rolling guide for welding machines is characterized in that it consists of two pulleys fixedly mounted on the support body for guiding the double-sided prism on one side and two fleece bearing pulleys located at the ends of the leaf spring for guiding the double-sided prism on the other. A leaf spring jp fixed to the bracket releasably connected to the support body and a biasing screw for locating the overhung pulleys in a double-sided prism.

Vynález možno použiť pre zváracie automaty/ připadne pre montážně alebo manipulačně zari^i denia, kde sa nevyžaduje vysoká tuhost’ zariadénia.The invention can be used for welding machines / or for assembly or handling equipment where high rigidity of the equipment is not required.

Pri priamočiarom vedení vodiacich telies voči nosným na zváracích automatoch, využívajúcich motorické ustavovanie horáka voči zvarovému spojů sa vyžaduje bezvólóvé vedenie, nízké odpory, citlivé a přesné prestavovanie pri relativné menších nárokoch na tuhost’. Valivé vedenia zváracích automatov používajú vo funkcii valivého elementu buď kladky s vymedzovaním vole excentrom, alebo valivé gulkové puzdrá na kruhových tyčiach. Kladky s excentrickým ustavením nedávajú možnost’ bezvólového vedenia s predpátím. Vedenia s gumovými puzdrami vyžadujú vysokú presnosť výroby tyčí, kruhové tyče sú podopreté na koncoch, a preto sú poddajné; gulkové puzdrá sú citlivé na prašné prostredie zváračských pracovísk.Linear guiding of guide bodies to carriers on welding machines using motor torch alignment with weld joints requires free lead, low resistances, sensitive and accurate adjustment with relatively less rigidity requirements. The rolling guides of the welding machines use either the rollers with the eccentric delimitation of the dude or the rolling ball bushings on the round bars as a rolling element. Pulleys with eccentric alignment do not give the possibility of a free-running guide with prestressing. Guides with rubber sleeves require high precision rod production, the round rods are supported at the ends and therefore flexible; ball bushings are sensitive to the dusty environment of welding workplaces.

Uvedené nevýhody sa do značnej miery odstránia predpátým prizmatickým valivým vedením pre zváracie automaty podlá vynálezu. Jeho podstata spočívá v tom, že pozostáva z dvoch kladiek pevne uložených na nosnom telese pre vedenie obojstrannej prizmy z jednej strany a z dvoch letmo uložených kladiek umiestnených na koncoch listovej pružiny pre vedenie obojstrannej prizmy z druhej strany. Listová pružina je upevněná na konzolu rozoberatelne spojenú s nosným telesom a predpínacou skrutkou pre dosadnutie letmo uložených kladiek do obojstrannej prizmy.These disadvantages are largely eliminated by the preloaded prismatic rolling guide for the welding machines of the invention. It consists of two pulleys fixedly mounted on the support body for guiding the two-sided prism from one side and two two-spaced pulleys located at the ends of the leaf spring for guiding the two-sided prism from the other side. The leaf spring is fastened to a bracket releasably connected to the support body and a biasing screw to engage overhung pulleys in a double sided prism.

Výhody predpátého prizmatického valivého vedenia pre zváracie automaty podlá vynálezu sú v tom, že vodiace teleso i valivé vedenie má tuhost’ orientovanú v rovině kladiek, v ktorej pósobia dynamické sily pri motorickom ustavovaní horáka voči zvarovému spojů, pričom obojstranná prizma vystužená krytom má podstatné vyššiu tuhost’ než kruhové tyče v doteraz používaných vedeniach. Predpatie móže byť vysoké, lebo posobí do obojstrannej prizmy a nedeformuje vodiace teleso. Kladky upevněné na listovej pružině dobré dosadnú do obojstrannej prizmy a nosné teleso je potom vedené štyrmi kladkami. Kladky upevněné na listovej pružině umožňujú pre výrobu vedenia použit’ obojstrannú prizmu s váčšími výrobnými toleranciami a zaisťujú zníženie citlivosti mechanizmu na prašné prostredie.Advantages of the prestressed prismatic rolling guide for welding machines according to the invention are that both the guide body and the rolling guide have stiffness oriented in the plane of the pulleys, in which dynamic forces are applied when the torch motor aligns with the weld joints. than round bars in hitherto used guides. The forepart may be high as it will fit into a double-sided prism and will not deform the guide body. The pulleys mounted on the leaf spring fit well into the double prism and the support body is then guided by four pulleys. The pulleys mounted on the leaf spring allow the use of a double-sided prism with increased manufacturing tolerances for the production of the guide, and reduce the mechanism's sensitivity to the dusty environment.
