Description
The present invention changes a kind of method and a kind of layout that cutter holder comes processing work in process equipment.According to the present invention, cutter holder is removed from Working position, and is changed by another cutter holder.
The polygon mounting seat that cutter holder is designed to have replaceable device is on record.There are many cutter holders to come mounting cutter on the limited area of the side direction of this polygon mounting seat.Mounting seat is made periodical rotation around central shaft, thereby each cutter holder is brought into Working position.
The shortcoming of this method and layout is, bring Working position into for another there being the mounting seat of other cutter holder, must unload the mounting seat of whole heavy and complicated large-scale band cutter holder down from working machine, transport back and leave in the gatherer, then, the mounting seat of another band cutter holder is transported to the working machine place and installed.Therefore, in the time need going to change the mounting seat that has whole cutter holders, must transport the latter is whole, so installation period in this system or nonproductive time are longer with another mounting seat with cutter holder.
At last, be contained in the cutter holder number on the same mounting seat, for example the drill bit number just is restricted on structure.From a structural point, mounting seat must be placed in the working machine with very high precision, thus those the cutter holder on Working position must be with very high precision location, this also is a shortcoming.
Therefore, a target of the present invention provides can change a kind of method and a kind of layout that cutter holder comes processing work in process equipment, and it has avoided the shortcoming of former technology.
Particularly, a target of the present invention provides a kind of method, according to this method, on the work in-process heart or the process equipment, no matter how many cutter holders can both be in ready position, without long transportation route just can be unblocked ground change cutter holder fast, and to have only cutter holder and process tool thereof be to interfix, to strain and to connect with drive unit according to required precision, like this, cutter has been located on the desired Working position.
Another target of the present invention provides a kind of layout that can implement the inventive method.
Follow these targets and hereinafter with definite target, briefly, a feature of the present invention is present in the method that is made of following several steps:
When a cutter holder is in Working position, be in ready position be positioned at drive unit another cutter holder and (perhaps) minimum tool rest on every side with predetermined form;
The cutter holder on Working position and drive unit together to ready cutter holder place moving linearly;
The cutter holder that before had been in Working position is entirely thrown off with drive unit automatically, and remains on this position, simultaneously drive unit is further moved on to terminal location, and it is stopped;
After cutter holder is thrown off and drive unit do between further moving period or after, make the stroke of the cutter holder work of the cutter holder of disengagement and preparation with respect to drive unit;
After stroke motion finishes, the cutter holder that has moved is rotated around vertical rotation axis, this cutter holder just is brought to the installation site before drive unit like this;
The cutter holder of reverse stroke takes cutter holder to deposit position after rotating and finishing;
Make drive unit in the opposite direction to the preparation cutter holder motion that is in the installation site, and between further moving period, they are linked up fixing and tension.
If the present invention according to the applicant implements this method, need only fast and effectively move less quality in the stage.And can provide any amount of cutter holder as required.
An outstanding advantage of the inventive method is that the speed of refitting cutter holder is very fast.In one embodiment, the reset time of cutter holder has only 5 seconds or shorter for instance, does not also need the spend labour simultaneously.Refitting is meant that another cutter holder enters the time interval of installation site on the drive unit.For example can automatically make the cutter holder location and finish whole refitting work.
The short and material stock removal rate height, the inventive method can also be shifted gears without manpower except non-cutting time.The inventive method is suitable for all cutter holders, as the cluster head drilling head, and milling head, the equating rotary head, rotary head, the accurate rotary head that the band cutting is revised, gage outfit, the test head, angular milling cutter head and location milling head, gun drilling is first-class etc.The system that the inventive method is not limited to pre-determine and certain in advance good cutting head number.This method available digital computer control.
According to another characteristic of the invention, proposed a kind of layout, it comprises a cutter holder assembly of being made up of tool guide and knife rest: with a plurality of replacing cutter holders and drive unit that drives all cutter holders of motor driving.In order to change cutter holder, on drive unit, adorned a rotating more ring change.Having above-mentionedly changes more that the above-mentioned knife rest of above-mentioned drive unit on above-mentioned tool guide of ring change is movably at Working position on radial position or reverse position.
Layout of the present invention adapts to the different processing purpose that require, workpiece series and annual production.It is mounted and removable, and this is not always the case to lathe and control thereof and link gear.Layout of the present invention can be assembled into single lathe or be assembled in the linked system, perhaps can be assembled into one as the structural member in automatic assembly line.
Compare with so-called machining center, the cardinal principle of layout of the present invention is not change the single main shaft of different cutters in process equipment.Whole cutter holder all will be changed, and its design adapts with processing tasks.For example, charged source and be used for the milling head of the rigid blade arbor installation component of cutting head, perhaps equating rotary head, one of them main shaft, the equating rotary head, the equating disk drives and stroke measurment all is included in this rotary head.Simultaneously, the single main tapping of changing single cutter automatically also can be used in the layout of the present invention.
Cutter holder can be changed in the process-cycle or semi-automatic or manual replacing when refitting automatically, decides on requirement separately.System does not limit the quantity of cutter holder.The size of replacing system and cutter holder and quantity thereof are irrelevant, are that open or unrestricted in this respect.Importantly its feature is that the replacing time is short and the cutting time is short in all cases.
Except concerning maintenance, good accessibility being arranged, to change for cutter holder, good accessibility also is an advantage.
