TQM Itaca Technology realizes complete lines for the control of brake discs and brake drums.

These lines are equipped with an independent system for the movement of the pieces composed of motorized roller conveyors and portals with special pincers for the catching of the piece. They are directly inserted in the production line. They have a modular structure and they can integrate the dimensional and geometric control, the frequencies control, the cracks control, the marking and the separation of good parts/rejects.

They are managed by a supervisor software called Italine^© , which dialogs with all the other measuring software (Itageo 6^©, Itasonic 2010^©, Itamatic^©) and which gives all the necessary information relative to the transiting parts or to the measured parts for each single station and global.  

The lines are realized according to customer’s specifications.

ELECTRONIC MEASURE AND ANALOG PROBES 

TQM Itaca Technology provides its gauges with customized HBT analog probes. Our probes are available also as single articles with competitive prices.
Here below some of the most used models (other models available):

AX/0.5: measuring field +/- 0,5 mm

AX/1: measuring field +/- 1 mm. Also available with cable exit at 90° and with pneumatic retraction.

AX/5: measuring field +/- 5 mm. Also available with cable exit at 90° and with pneumatic retraction.

Interfaces for the connection of SPC Itastat 6 Measure stations

There are available different types of interfaces for the connection of analog probes to the Itastat 6 Measure stations. The choice of the interface depends on the measuring needs.
For static measures, with gauges with manual loading/unloading, and characteristics with wide tolerances, the interfaces with the connection by usb can be adequate.
For dynamic measures, automatic gauges with loading/unloading made by a robot or by a manipulator, many probes and restricted tolerances it's advisable to use the interface iDaq4Geo

The software Itageo 6^© is extremely flexible and it can be used to control all the parts with circular or cylindrical shape which rotate on an axis, vertical or horizontal. It can manage different types of sensors, also without contact, like for example triangulation lasers or bidimensional lasers. 
The use of this kind of sensors enlarges the potentiality of Itageo 6^©, allowing the control of surfaces which are impossible to control with the classic contact probes.  
T.Q.M. Itaca Technology has realized stations for the control of flywheels, included the control of the external ring gear using laser sensors, with a detailed analysis of the threaded profile.

In the picture above note the laser sensor completely closed in a protection with automatic gate, with pneumatic activation, which assures the respect of the requested safety standards.

For the control of brake drums, TQM Itaca Technology has developed stations complete of mechanics and software, called Itageo 6©. These stations, also called “Workshop Roundness Measuring Instruments”, measure the drums with the same logic of a laboratory roundness measuring instrument, obtaining comparable results, with cycle time of about 15 seconds. The management of more probes at the same time allows to have very complex control plans without influencing the cycle time. It’s provided the automatic management of the verifications and master resetting, for the control of the gauge stability. 

The measuring cycle is completely automatic, also in the version with manual loading/unloading.
The stations can be retooled, can be integrated with FRF control (Natural vibration frequencies), with marking systems to guarantee the 100% traceability, with cracks control with Eddy Current technology.
There are available different configurations, in order to insert the gauge in any type of production line. The stations can be served by anthropomorphic robot or supplied with load/unload portal . In the scheme below there are the characteristics which can be measured with the gauges Itageo 6^©.

Measuring Principles

The measuring software Itageo 6© is optimized for the dynamical control of objects put in rotation, and it allows to control diameters with a single probe. The result is the simplicity of mechanical configuration and type change.
To guarantee the highest precision and reliability of the measurement, Itageo 6© works on the same measuring principles as the laboratory roundness measuring instruments: the piece is put in rotation on a precision mandrel, angular control via encoder, one contact probe on each section to be measured, acquisition of at least 7.200 points/turn for each section analyzed, reconstruction and analysis of the obtained profiles.
The analysis of the profiles allows:
•    Display in real time of the profiles, a great help to identify the possible causes of technical problems due to the processing of the same pieces.
•    Fourier Analysis, with breakdown of the form errors in the single component, with possibility to manage different tolerances for each error.
•    Possibility to implement filters like the roundness measuring instrument.
•    Possibility to implement dirty filters.
•    Possibility to analyze for sections of circumference : ex. roundness every 30°.
•    Possibility to compensate the rotation errors induced by the mandrel.

The mechanics

The drum is put on a precision mandrel, with three supporting plans placed at 120°, and three locking jaws, placed at 120°, out-of-phase respect to the supports. The internal probes, for the measuring of the supporting plan, of the central hole, of the braking surfaces, etc… are contained in special interchangeable masks which allow a fast type change and which ensure the correct positioning of the probes. The external probes, which can be all easily repositioned, are mounted on an automatic slide that during the load/unload phases is out of work area. The slide is equipped with an anti-collision safety system.

The software Itageo 6^©

Itageo 6^© is the most advanced software for the management of automatic stations for the control of brake discs and brake drums. It is able to manage the following functions:
1.    Management of dynamic, geometric and dimensional measurements of brake discs and brake drums.
2.    Immediate and visual configuration of the station.
3.    Creation of control plans with rapid and intuitive graphic support.

12.  Cut-off filter of the high frequency harmonics.
13.  Settable dirty filter.
