Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with specific embodiment, and with reference to accompanying drawing, the utility model is described in further detail.
For can the utility model be illustrated more clearly in, hereby lifts preferred embodiment and coordinate graphic being described in detail as follows.Shown in please refer to the drawing 3 to Fig. 5, be intelligent control system and the control flow thereof of the machine tool of the utility model one preferred embodiment.It is applied in automation field, in order to detect the position of rotation being installed in a rotatable object of the Power output end of automation, and is revised mistake or the deviation of mechanical action by compensation way in real time, smooth and easy to guarantee running.For ease of explanation, in the present embodiment, this intelligent control system is applied to automatic tool changer for example but not as limit, it comprises a programmable logic controller (PLC) 10 (Programmable Logic Controller, be called for short PLC), servo-driver 20, servo motor 30, rotating machine sets 40 and two scramblers, be respectively scrambler 50 and scrambler 60.
This programmable logic controller (PLC) 10 is electrically connected with this servo-driver 20, and this servo-driver 20 is electrically connected with this servo motor 30 again.This servo motor 30 is linked with one first tumbler by a gear train of this rotating machine sets 40.In the present embodiment, this first tumbler is the disc type tool magazine 42 being mounted with most different cutter, and it is connected to the Power output end of this gear train rotationally.More particularly, in the program of this servo-driver 20 according to this programmable logic controller (PLC) 10, and when sending to this servo motor 30 steering order driven or brake, this servo motor 30 soon orders about this disc type tool magazine 42 via this gear train and rotates or stop, and selects cutter operation to complete.In the present embodiment, this gear train comprises reducing gear 44,1 first gear 46 and one second gear 48, wherein this reducing gear 44 is connected to the output shaft of this servo motor 30, and this first gear 46 connects this reducing gear 44, in order to this second gear 48 power transmission extremely engaged.This second gear 48 be combined as a whole with this disc type tool magazine 42 and together with rotate.Should be noted that, the visual actual demand of this gear train and with the gear case including index cam replace reducing gear.
This scrambler 50 is absolute type encoder (absolute encoder), and it has a rotating main shaft 52, and to be concentric with this disc type tool magazine 42, mode is arranged this main shaft 52.This scrambler 50 is electrically connected this servo-driver 20, and it is in order to detect the position of rotation of this disc type tool magazine 42, and feeds back the electric signal after a decoding to this servo-driver 20, and this electric signal comprises the position of rotation represented in a compiled manner.As for this scrambler 60, be also absolute type encoder, it to be installed on this servo motor 30 and to be electrically connected this servo-driver 20, and this scrambler 60 is in order to detect the rotating speed of the rotor of this servo motor 30, and feedback decoding gives this servo-driver 20.In above-mentioned, this main shaft 52 is the position of rotation being linked to and this second gear 48 recording this disc type tool magazine 42.Certainly, in the other cases, obtain and this main shaft 52 is directly linked to this disc type tool magazine 42 to detect its position of rotation.
In above-mentioned, when this disc type tool magazine 42 rotates, it by initiatively and constantly detect its position of rotation, and is fed back to this servo-driver 20 by this scrambler 50 with translating to electric signal duration.When the position of rotation of institute's test disks formula tool magazine 42 puts in place, this servo-driver 20 maintains the program according to this programmable logic controller (PLC) 10, sends steering order to this servo motor 30; Otherwise, when the position of rotation of institute's test disks formula tool magazine 42 is failed to put in place and is had deviation, the electric signal that this scrambler 50 feeds back, this servo-driver 20 is then provided to adjust the rotating speed of the rotor of this servo motor 30 and/or rotational angle, to make this disc type tool magazine 42 can revise deviation by the mode compensated in real time, to guarantee that each position of rotation of this disc type tool magazine 42 puts in place really.In other words, the mode of the utility model in order to detect the end of power transmission and to follow the trail of, really improves known structure and adopts and passively send abnormal information, and must shut down to carry out the inconvenience that inspection and repair shop brings; More and, the mode that should detect with end and follow the trail of, makes the precision of the gear train (such as reducing gear) configured in automation have more selection elasticity, so moderately can reduce costs expenditure.
Must one to carry, should, in order to the scrambler 50 of test disks formula tool magazine 42 position of rotation, be good to be installed in the Power output end of gear train.Therefore, except the mode arranged for concentric with this disc type tool magazine 42 disclosed except above-described embodiment, also can be installed in as shown in Figure 6 on the second tumbler for this first gear 46, can reach equally and detect in real time and the effect of timely compensation deviation.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
