Embodiment Construction

[0016] exist figure 1 In , a machine tool (in particular a grinding machine) is schematically and partly shown and denoted by reference numeral 1 .

[0017] The machine tool 1 comprises a frame 2 rotatably supporting a spindle 3 by means of interposed bearings (not shown), so that the latter can rotate about an axis of rotation 4 .

[0018] The main shaft 3 supports grinding wheels 5 via respective grinding wheel hubs, the latter being removably fixed to the main shaft 3 by means known and not shown, including for example cone clutches. The spindle 3 and the grinding wheel hub define the rotating part of the machine tool 1 . The main shaft 3 has a central axial opening 6 in which the rotating part of the balancing system with a balancing head 7 is housed. The balancing head 7 is of known type and comprises two balancing masses 8 eccentric with respect to the axis of rotation 4 , and an associated electric motor 9 for adjusting the angular position of the balancing masses 8 ....

Abstract

Balancing system for a rotating spindle (3) of a machine tool (1); the balancing system has a rotating part comprising a balancing head (7) with at least one balancing mass (8) and at least one electric motor (9) which is adapted to regulate the position of the balancing mass; the rotating part also includes a vibration sensor (10) and a control system (11) with at least one hardware (12) and at least one software (13) executed by the hardware; the balancing system also includes a two-way contactless communication system (14) which establishes communication between the rotating control system and a fixed processing and control electronics (15) connected to a machine tool control unit (20). The software of the control system features: a management application (19) which performs all the management of the balancing head and the vibration sensor during normal operation, and a service application (18) which, when the control system is powered after a suspension of the power supply, automatically starts up and starts the management application or, if a software update is required, overwrites the existing version of the management application with a new version.

Description

technical field [0001] The invention relates to a balance system for a rotating spindle of a machine tool and a related control method Background technique [0002] For example, in patent applications EP0690979A1, EP1870198A1 and EP3134980A1 a balancing system for a rotating spindle (hub) of a machine tool, in particular a grinding machine, is described in which the spindle rotates relative to a frame and supports (at least) one grinding wheel. The balancing system comprises a rotating part with a balancing head which is usually housed in an axial opening of the main shaft, substantially corresponding to the grinding wheel, or arranged at one end of the main shaft, also axially aligned. The balancing head comprises at least one balancing weight eccentric with respect to the axis of rotation, the position of which is adjustable and controlled, for example, by an electric motor. [0003] Typically, the rotating part also carries vibration sensors, often associated with the ba...
