Abstract

L'invention a trait à un dispositif de vérification et de réglage de tournevis automatiques sur un couple de serrage déterminé. Elle a pour objet un tel dispositif équipé d'un dispositif de charge pouvant appliquer un couple de rotation reproductible pour le tournevis automatique et équipé d'un élément de mesure de couple de rotation entre le tournevis automatique et le dispositif de charge en vue de l'indication du couple de rotation appliqué par le tournevis. Le dispositif de charge est réalisé sous la forme d'un frein à friction 2 équipé d'éléments de friction pouvant être appliqués hydrauliquement et un dispositif hydraulique est prévu, permettant un accroissement de pression reproductible, réglable en fonction de la valeur maximale, en vue de l'alimentation hydraulique des éléments de friction. Application notamment aux outils de serrage pneumatiques.The invention relates to a device for checking and adjusting automatic screwdrivers to a determined tightening torque. It relates to such a device equipped with a load device capable of applying a reproducible rotational torque for the automatic screwdriver and equipped with an element for measuring the rotational torque between the automatic screwdriver and the load device with a view to l indication of the torque applied by the screwdriver. The load device is realized in the form of a friction brake 2 equipped with friction elements which can be applied hydraulically and a hydraulic device is provided, allowing a reproducible pressure increase, adjustable according to the maximum value, in view of hydraulic supply to the friction elements. Application in particular to pneumatic tightening tools.
