DEVICE FOR ACTIVE CONTROL AND MEASUREMENT OF ACTUAL DIMESIONS OF EXTERNAL SURFACE OF ITEM OF SHELL OF REVOLUTION TYPE Russian patent published in 2011 - IPC G01B5/00 

FIELD: machine building.

SUBSTANCE: device consists of base for installation of item. A beam bearing a module of transfer is rigidly attached to the base. In the module of transfer there is arranged a device for pickup of information. The device consists of a carriage travelling lengthwise along the item, of a servo-motor and of an encoder connected to a servo-amplifier. A sensor of linear transfer with a probe is secured on the carriage; the probe contacts surface of the item. An output of the servo-motor and encoder is connected with an input of the servo-amplifier, while the output of the servo-amplifier and output of the linear transfer sensor are connected to the inputs of units of computer interfaces. To avoid warp and for smooth transfer of the measuring probe there used a damper. A sealed jacket secured on the beam protects the module of transfer with the device for pickup of information from dust and moisture. The device is equipped with rated screws to align axis of the module of transfer with axis of a controlled item. A turner can be used as a base for installation of an item.

EFFECT: device of high precision and accuracy for control and measurement of parametres of curvilinear external surfaces of revolving shells.
