Electric nutunner motors with computerized control


Electric nutunner motors with computerized control

 

High precision, utmost control

The brushless electric nutrunner motors with computerized control, that can be used on different types of joint (same model for different torques). Thanks to their modularity, compactness and versatility, they are able to solve many tightening needs, also very complex. These solutions are necessary when you have to control, monitor and constantly verify the entire assembly process including the memorization of the tightening datas. They are ideal when it is indispensable to assure the certified quality of final products. Tightening solutions comprise: A. Electric nutrunner motor with indirect or direct computerized torque control B. Feed unit to feed the motor and supply correct voltage and current parameters C. Computerized control unit is checking and monitoring the assembly cycle D. Kit of cables for connecting motors and units.

 

Current control electric nutrunner motors

Current control electric nutrunner motors

Quality guarantee with a precise tightening

The current control electric nutrunner motors with the feed and the control units, guarantee the maximum quality of tightening process thanks to indirect torque/angle control where the parameters are achieved by measuring the current absorbed by the brushless motor and by appropriate sensors. They are suitable for use in multispindle units for fastening operations where more screws are fastened simultaneously and when it is important to guarantee the final quality of the product. (e.g. motorvehicle brake systems head of a piston engine, cover tap of a water heater, etc.).

 

Electric nutrunner motors with torque/angle control

Electric nutrunner motors with torque/angle control

Precise tightening absolutely under control to skip any post-process control

The electric nutrunner motors with torque/angle control are fitted with an electronic transducer to read the torque applied to the screw; while the angle is read directly by appropriate sensors. These motors together with the feed and control units guarantee extreme precision and accuracy and maximum quality of the tightening process and of the assembled product.

 

Feed unit

For nutrunner correct electrical feed.

Used to feed the motor and supply correct feed parameters (voltage, current, etc...) following data pre-set in the control unit. The unit is equipped with a control system for tension, voltage and temperature values, dispersion towards ground and interruption of ground wire. Any possible failure is flashed by means of luminous diodes and the system stops immediately. Available two versions:  TOD-L and TOD-H

 

Control unit

Control unit

TOC and TOCS: everything under control

Computerised control units for MCB and BL electric nutrunner motors both direct and indirect torque/angle. They detect both OK and NOT OK cycles besides the torque/time values which can be easily stored (7.000 tightening for each channel). Statistics (CP, CPK, Range, Average, Sigma). They are equipped with an alphanumeric display and with a software that permits high flexibility for every tightening need. They are available in 1-channel or 2-channel versions: controlling one motor or two motors, which can be also different, working synchronously or asynchronously. The complete and simple programming menus offer:Tup to 30 tightening programmes with possibility to insert 20 instructions; setting various tightening strategies. Easy to use.

 

Feed and control unit:

TCS- B feed and control unit: BASIC solution

Tightening Control System Basic: for electric nutrunner motors 15/25/50MCB with current control. BASIC model that integrates controller and driver. It displays OK/NG cycles and torque angle values. It allows setting of 5 tightening strategies: torque, torque/angle, angle/torque, screw feeding, untightening. Supplied with programming software,  4 programmes (max 50 instructions),  RS 232 serial output for print or PC,  5 5 optoisolated Input/Outputs,  Upon request external memory
