Embodiment Construction

[0024] Referring to the accompanying drawings, they show a protection device for a rotating grinding wheel made of abrasive material according to the invention.

[0025] The protective device comprises a housing structure comprising a fixed part 11 and a movable part 12 with respect to the axis of rotation of the grinding wheel fitted on the grinding machine.

[0026] The movable part 12 is fitted on a pair of scraping guides 13 having a low coefficient of friction and located on both sides of the grinding wheel.

[0027] The fixed part 11 comprises a covering and protecting element 15 of the accommodation structure of the grinding wheel 16 , which is restrained on the fixed part 11 , for example by means of a hinge 14 .

[0028] On the fixed part 11 of the housing structure is bound a motor or drive device, for example a pneumatic cylinder 17 , a rod part 18 whose free end is hinged on the movable part 12 . An electromagnetic blocking element 19 of the movable part 12 relati...

Abstract

A protection device for a grinding wheel, comprising a containment structure equipped with an operating opening (22) for a grinding wheel (16), wherein said containment structure comprises a fixed portion (11) and a movable portion (12) which can be moved with respect to the fixed portion (11) by means of a motor (17) and which can be blocked with respect to the first fixed portion (11) by means of a magnetic blocking unit (19), the device also comprising a sensor (26), adapted to automatically detect the position of the movable portion (11) and control means (27) of the whole device also being envisaged.

Description

technical field [0001] The present invention relates to a protective device for grinding wheels, in particular but not exclusively for rotating grinding wheels made of abrasive material. [0002] The invention can in fact also be used for other types of grinding wheels, such as so-called "CBNs", which have very limited wear. Background technique [0003] Consider, for example, cylinders of laminators, cylinders of paper mills and other grinding wheels in the field of grinding, for example rotating grinding wheels made of abrasive material, which act on cylinders or similar workpieces being processed. [0004] In such processing tools, the grinding wheel rotates within a guard or shield. The housings for these grinding wheels must be designed and constructed to contain in a safe condition any possible debris that might be released during machining and in the event that the grinding wheel breaks or bursts during rotation and engagement with the cylinder being machined of. ...
