Elongated part e.g. rear end anti-rolling suspension bar, guiding and driving device for use in shot blasting installation, has driving roller returned in contact against elongated part to apply part against another driving roller

摘要

#CMT# #/CMT# The device (1) has a driving roller (7a) provided with a V-shaped groove and driven in rotation according to an axis (51a). The roller is contacted with an elongated part at flanks (8a, 9a) of the groove and acts by friction at the level of contacts between the part and the flanks of the groove for movably driving the part. Another driving roller is idly assembled in rotation around another axis non-parallel to a direction (10) and is returned in contact against the part by an action of elastic return to apply the part against the roller (7a). #CMT#USE : #/CMT# Device for guiding and driving an elongated part e.g. rear end anti-rolling suspension bar, of a motor vehicle, in a shot blasting installation (claimed) that cleans the elongated part in order to prepare a surface for an ulterior surface processing operation e.g. painting and plating operations. #CMT#ADVANTAGE : #/CMT# The configuration of the device permits limitation of speed variations of the conveyed elongated part, thus improving quality of shot blasting process of the part. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an evasive perspective view of a device for guiding and driving an elongated part. 1 : Elongated part guiding and driving device 7a-7c : Driving rollers 8a-8c, 9a-9c : Flanks 10 : Direction 51a-51c : Axes.
