2 Decription The pre fit controller ML85C wa pecially developed for monitoring fitting procee with the aim of enuring quality already during production. It monitor for example the phyical quantitie force and diplacement, together with their inter relationhip. orce/diplacement coure are evaluated uing the tolerance window method. Depending on the application, you can chooe between four method. Thee method have been pecially developed for pre fit procee. Pre fit monitoring with the MGCplu meaurement ytem offer the following advantage, in addition to it 100% quality control: faulty connection are recognied even during the fitting proce avoidance of machine and tool damage tatitic proce control optimum proce control and high proce ecurity through proce viualization ervice friendline i enured through the modular tructure HBM offer the complete olution from the tranducer through the meaurement electronic to the evaluation oftware. Up to five module can be intalled in one MGCplu houing. The ML85C pre fit monitoring module work with all ingle channel amplifier. Aement of the pre fit proce The fitting window upervie the actual pre fit tak. You may define up to 6 fitting window. 4 aement method are available for the evaluation: max itting window, rectangle N N N min left right Evaluation: coure of curve Evaluation: coure of curve The curve mut enter the fitting window at the ide, mut not tray outide max and min and mut leave the window at the ide again. Evaluation min N Evaluation max N Evaluation mean value Only min i monitored. Only max i monitored. The force i averaged and evaluated over the path of the window. HBM 2

3 Evaluation The following window are ued for the evaluation: 1 alarm limit Limit at which an alarm will be triggered. Thi window i ued for the protection of the motor. 1 range window Define the overall range of the force/diplacement diagram within which all other tolerance window lie. 1 thread in window or evaluating the alignment phae, which i when the fitting piece are initially brought into contact and aligned. 1 6 fitting window or evaluating the fitting proce. 1 end window or evaluating the end phae of the fitting proce and terminating meaurement. (force) Alarm max Alarm limit Range window Thread in window Alarm itting window Alarm min S (diplacement) Coordinate ytem: The coordinate in the tolerance window can be entered in abolute or relative term. The relative ytem of coordinate i ued when the abolute poition of the fitting piece (e.g. bearing/haft) i not alway conitent. Relative diplacement coordinate In the cae of relative diplacement coordinate, only the relative movement of the two fitting piece from the tart poition or end poition i meaured. (force) End force Block force End poition Abolute, diplacement tranducer (mm) Relative diplacement coordinate Example: Pre fitting a bearing onto a haft. 40 mm Start poition Relative dipl Start poition 40 Target poition 0 Abolute diplacement coordinate Relative diplacement coordinate 3 HBM

4 Evaluation of curve with force relative window The curve below might reult from teting a locking lever for teering column, for example. In uch clamping procee it i important that the force increae teadily, reache a maximum value (which i within a defined tolerance range) and then fall off again (engagement poition). To evaluate thi proce you define fitting window 3 and 4 relative to max or min of fitting window 2. Thi mean that the ame curve form i alway evaluated. itting window 2 N Relative reference to max of fitting window 2 itting window 3 itting window 4 Evaluation method our evaluation method are available for the variou application. block force and ettling time tandtill recognition external top ignal target poition and ettling time The following example illutrate the different method. Block force and ettling time Thi method hould be ued if the end poition i defined by a mechanical limit. The end poition i recognied by the exceeding of the pecified force limit (block force). Overhoot (diplacement within the ettling time) E Example: Pre-fitting a bearing at block poition ÎÎÎÎÎ ÎÎÎ block B ÎÎÎ ÎÎÎÎÎ left right End poition Standtill recognition Thi method i ued when it i neceary to enure that the part which i to be pre fitted will remain under load in the end poition for a certain period. Standtill i automatically indicated when no change of diplacement i detected within the pecified time. min E ÎÎÎÎÎÎ Example: Bearing to be loaded with 3 kn for 5 econd in the end poition. left right ÎÎÎÎ ÎÎÎÎÎÎ End poition HBM 4

5 External top ignal In thi method the end poition i ignalled by an external tranmitter (e.g. proximity witch). E Proximity witch Example: Required poition indicated by proximity witch. min left right Target poition Target poition and ettling time In thi method the diplacement channel ignal that the end poition ha been reached. E Diplacement tranducer Example: Pre fitting a bearing with diplacement monitoring min S -target left -target right Target poition -target Control and ervice function The diplay and control panel i ued for etting up the device and preenting the meaured value. You can protect all the etup with a paword. unction uch a tranducer teting, tatu indicator, tatitic and digital and graphical preentation of the meaured value allow imple et up of the ytem, make troublehooting eaier and provide convenient opportunitie for evaluating the fitting procee.
