Background technology: two kinds of engravings are arranged since ancient times: a kind of is the plane, and another kind is three-dimensional.Along with the epoch are constantly progressive, former pure manual manipulation method is progressively substituted by machinery.And development is so far, although the mechanical engraving instrument the two can dual-purpose, true always the proof the effect of cam plane engraving Cui not.This be since enter the cutter degree of depth can only rely on hand-guided, with the sensation due to.Adopt this method, although handicraft Taoist priest how, all be difficult to depict exactly lines or an a bulk of smooth spill plane that the depth is consistent, operating wastes time and energy does not say, and effect is unsatisfactory again, and crooked, average narrow ground fulfils assignment reluctantly, and some is not even such as pure hand engraving effect, seeming a kind of progress, is that a kind of appreciation is degenerated in fact.For this reason, this invention has dropped into the fringe cost of minute quantity on the basis of existing technology, to a kind of support that can regulate arbitrarily carving depth of its configuration, just improved significantly this present situation, can be convenient, entirely fulfil assignment, not only works are delicate and pretty, and when operation example seemingly write easily like that, a kind of brand-new mechanic effect has appearred.Although omnipotent computer three-dimensional engraving technology is arranged at present, but it can't monopolize whole engraving market, its basic reason is: it can't instead of manual artistic effect and the randomness of engraving, can only do to medelling a bit with the engraving of advertisement character professionally, stay the large block space that it can't relate to forever to artistic work appreciation field.So the hand engraving industry is still vigorous so far, is found everywhere.
Summary of the invention: support only as the rotatable tool device near carrier, during use, by to the spiral mode of operation on the support, in the scope of setting, can regulate arbitrarily the cutter end and enter the object depth degree.This scheme is the technological highlights of this invention, is a novel engraving tool the most effective the simplest core technology that is born, and is to be different from the visibly different technical characterictic of prior art.This support is only to the generation effect when the regulation depth of rotatable tool device.It can be electronic making the power fork-like farm tool used in ancient China source of this cutter rotation, also can be pneumatic; The transfer mode of power can be directly, also can be indirect.So this support all has uncertainty to appearance geometry, power fork-like farm tool used in ancient China source and the transfer mode of match objects.The general idea of this invention is to be convenient hand engraving service.Drop on the basis of existing technology the fringe cost of minute quantity, configure a kind ofly to the adjustable support of the degree of depth, limit arbitrarily the cutter end and enter the object depth degree, effectively solve a few days ago the engraving person when engraving to the unmanageable difficulty of the degree of depth, reduce labor intensity, raise labour efficiency.This support advantage is that modern design is attractive in appearance, and structure is simplified compactness, stable and reliable for performance, and functional effect obviously is better than generally, and volume is little, lightweight, non-maintaining, easy-formation, easily grasp and durable when operating on the spot.
The specific embodiment: to the enforcement of present technique, should be formerly organic, configuration thereafter.The simplest method is to go to look for a more satisfactory motor (also can special to design to market.Special design, can adopt the trapezoidal dovetail groove combined method more convenient), after the purchase, again according to the related data of this machine, design support can be supporting with it, that can arbitrarily regulate carving depth.This support totally in two sub-sections: one is active bracket, and another is passive support.A limit and this machine of active bracket are combined into one, and packing in the groove of passive support in another limit, but has just finished by the screw rod up-down adjustment, and its principle is simple.Specific practice is: the electric carving tool take registration mark as DREMEL is example.Determine that at first the amplitude of accommodation up and down is 10 millimeters (this amplitude is fit to the general closed planar engraving to the requirements of the degree of depth), the screwed hole that to establish a diameter in the upper end of active bracket be the 6M millimeter, the degree of depth in this hole is 30 millimeters.There is nut this motor lower end, need only with a supporting plate (during batch production, this supporting plate can with compression molding of active bracket, need not to do in addition), one end of supporting plate is opened a circular hole consistent with motor lower end snail shank diameter, it is inserted in the original nut of rear usefulness fixes, again the other end of supporting plate is fixed on synthetic integral body in lower end of active bracket.In order to strengthen its steadiness, prevent that active bracket from vacillating now to the left, now to the right at this casing, just laterally load onto a very short and small arc strip topmost (such as batch production at active bracket, this arc strip can with compression molding of active bracket, need not to do in addition), respectively load onto a diameter at this two ends and be 3 millimeters location dowel, the length of this dowel and the thickness of casing are equal to, and coincide in casing and the perforate of dowel opposite position and its.So just both have been formed the three-point fix of inversion " product " font, bore an aperture that passes 6M millimeter screwed hole in the middle and upper part of active bracket again, be 3 millimeters tapping screws with a diameter, by regulating screwed hole equally, active bracket is fixed on the casing, and the length of this screw is as the criterion less than the member in this machine to hinder.By these ways, active bracket and this machine have just synthesized a solid integral body.The lower step will be the way of passive support: adjustable diameter and screw adjusting is established in the upper end of this support, and plane bottom plate is established in the lower end, one side the middle part establish up and down stroke groove of fastening screw, another side is established up and down stroke groove of active bracket.The diameter of this holding screw is the 4M millimeter, and effective length is 12 millimeters, and setting screw is in the active bracket middle and lower part.The width of the trip groove is consistent with the diameter of this fastening screw, and length is 14 millimeters.When active bracket regulating in the passive bracket groove put in place after, screw again this holding screw and fix (this screw relaxes when regulating, otherwise just transfers motionless).Distance (groove) between the passive support both sides is with the consistency of thickness of active bracket, the length of this groove is that active bracket enters slot length and adds 10 millimeters (path increments) again, when packing into active bracket in the groove, both are advisable with interference fits, and regulating puts in place is locked afterwards with holding screw.By above effort, can not become all the time when operating this degree of depth, telephone-moving is along the line according to quarter by all means, and example is write light like that like imitation.For engraving large tracts of land spill plane, if the anchor clamps of this machine load onto a little milling cutter successively fork-like farm tool used in ancient China to return the ground mill off just passable.To milling a small amount of corner of (less than milling cutter diameter), can use the cone cutter instead and process.The adjusting screw(rod) handle is located at the upper end, top of passive support.This adjusting screw(rod) is that to pass passive support upper end thickness diameter be that 6 millimeters hole and spiral are in the active bracket screwed hole.Very narrow together annular slot is arranged on this adjusting screw(rod), the position of this groove is consistent with the distance of passive support upper side card openning, when adjusting screw(rod) screws in active bracket screwed hole end, again the opening card is inserted and wherein blocks (this card exposes 3 millimeters when being inserted into the end, in order to transfer to during dismounting).When the spiral shell handle on the turn set screw, just can make active bracket in the groove on or under twitch.Here it is so-called adjustable in depth.The design of passive support lower chassis: make its support surely vertical, just must load onto in the lower end of passive support the chassis of a suitable size (such as batch process, this chassis can with compression molding of passive support, need not to do in addition), the circular arc geometric form of the shape approximation triangle on this chassis, keep to the side the stage casing point of edge on the one side on this shape chassis do the radius cutting of making an arc, and this stage casing point is corresponding with the central point of this machine.Degree for cutting under the prerequisite that does not affect the overall appearance effect, is as the criterion to reach absolute visual field.But must be noted that for equaling or less than the machining object (such as seal and so on) of this chassis area, need doing in addition a larger level clamp it is clamped and can use.When delineating long straight line, for the edge on convenient chassis can be against the edge delineation of chi shape thing, it is 3 millimeters according to the anchor clamps maximum permissible value on this motor, so chassis that should be after being cut is take the stage casing point as the boundary, outwards outstanding 2.5 millimeters on both sides are not so that cutter can hurt this chi shape thing when keeping to the side to delineate.That is to say, suppose it is at full capacity 3 millimeters delineations, the edge of cutter carpenters square shape thing also had 1 millimeter surplus when battle was leaned on.The trip adjusting screw(rod) has been used of a specified duration can be gapped, if holding screw does not screw, might cause the supposition position, brings negative effect for dark precision.Occupy this point and consider, with a diameter be 3 millimeters little spring under the chassis vertically to peaking at this adjusting screw(rod), make this screw rod forever be in upwards abutting orientation, the location is the most reliable under this state, holding screw lax any has not big harm.Because 10 millimeters up-down adjustment space is arranged in the groove, spring is crooked in this space in order to prevent from regulating downwards, just fills a conduit that exposes 12 millimeters in the spring eye of active bracket.Because space length only has 10 millimeters in the groove, so these additional 2 millimeters corresponding spring eyes in the lower end at this groove are opened the sulculus of 3.2 millimeters of dark 2 mm wides, allow spring guide from then on enter.So not only can prevent spring bending, the surface of this conduit also plays guide effect during to the active bracket up-down adjustment.In order to promote clearness, in time process the dust that the icking tool periphery occurs when operation, the plastics small fan of doing an external diameter and be 4 centimetres, aperture and be 3 millimeters symmetry two blades is contained on the tool bar, and the backplate of setting up defences.During operation, the inconvenience that brings for the electric wire that alleviates this machine is just loaded onto one at this electric wire and is torn the patch band and it is wrapped on the wrist of operation, when idle, and use when this band can be done it bundle.And at support the degree of depth and hand of spiral effect mark are set.
