Vynález sa týká držiaka vyvrtávacích tyčí a osových nástrojov pre zvislé sústruhy, umožnujúceho nastavenie osi vyvrtávacej - tyče .alebo osového nástroja do osi obrobku.BACKGROUND OF THE INVENTION The present invention relates to a boring bar holder and axis tools for vertical lathes, enabling the axis of the boring bar or axis tool to be aligned to the workpiece axis.
D^teraz'známe držiaky vyvrtávacích tyči a osových nástrojov.neumožňujú změnu polohy osi upínacieho otvoru osových nástrojov vo^i osi obrobku. Súososit upínacíeho otvoru vyvrtávacích tyčí a najmá osových nástrojov sa dosahuje buď přesným polohovanim strediaceho- otvoru v upinacej ploché stroja voČi upinacej doske a přesným polohovanim upínacieho- otvoru voči polohovaciemu čapu na upinacej ploché držiaka, ktorý zapadá do strediaceho otvoru v upinacej ploché stroja, alebo vrtáním upínacieho otvoru v držiaku.namontovanom na stroj pomocou nástroja upnutého v upinacej doske. .Zhotovinii strediaceho otvoru a upinaci^e^ho otvoru vrtáním na stroj je značné náročné a prioom nie je zaručená súososč osového nástroja a upinacej došky pri roznych prevádzkových teplotách stroja. Držiaky s upínacím otvorom . zhotoveným priamo na stroji, pre ktorý sú určené, nie sú .pouužtelné pre iné stroje, aj keď sú tieto rovnakého tvaru a velkosti. Z uvedeného vyplývá nevhodnost týchto držiakov pre sériová výrobu.Known holders of boring bars and axial tools are now known to allow a change in the position of the axis of the clamping bore of the axial tools along the axis of the workpiece. The alignment of the boring bar clamping bore and in particular the axial tools is achieved either by precisely positioning the centering bore in the clamping flat machine against the clamping plate and precisely positioning the clamping bore relative to the positioning pin on the clamping flat holder that fits into the centering bore in the mounting hole in the holder mounted on the machine by means of a tool clamped in the clamping plate. The drilling of the centering hole and the chucking hole by drilling on the machine is considerable and at the same time the coaxial of the axial tool and the chuck is not guaranteed at different operating temperatures of the machine. Holders with clamping hole. made directly on the machine for which they are intended are not usable for other machines, even if they are of the same shape and size. This implies that these holders are unsuitable for mass production.
