Description

Woodworking tool worktable

Technical field

The present invention relates to a kind of Woodworking tool worktable, particularly a kind of electric wood milling worktable is applicable to sheet material workpiece is processed.

Background technology

The carpenter often processes and is undertaken by workbench, perhaps sheet material is fixed on the workbench, and the hand-held wood working tool of operator is processed, and perhaps wood working tool is inverted to be installed under the workbench, and the operator passes sheet material and processes.Wherein, comparatively common wood working tool is that bakelite mills, comprise that fixed pedestal formula bakelite mills (fix-base router) and the formula bakelite of being absorbed in mills (plunge router) two kinds, the formula bakelite of being absorbed in mills corresponding handheld operation, fixed pedestal formula bakelite mills then to be inverted usually and is installed in the use of workbench below, come down to the operator according to the figure line on the sheet material, mobile sheet material carries out the process of milling.

For the milling of sheet material, according to the requirement of milling, can be divided into two big classes, a class is sheet material to be milled logical, i.e. the figure line that milling go out to connect on sheet material makes that two surfaces are consistent up and down; Another kind of is the milling line of publishing picture on a surface of sheet material only, because this milling work is not mill logical sheet material, so can be described as half logically, does not promptly mill logical.

For milling logical sheet material, industry uses fixed pedestal formula bakelite to mill usually, is about to the below that its inversion is installed in workbench, by regulating depth adjustment, makes milling head pass opening on the workbench.At this moment, the operator is placed on sheet material on the workbench, and milling head then can mill logical sheet material, and then the operator moves sheet material according to the figure line, and milling work can be finished smoothly.Because in whole milling process, milling head all is visible, thereby milling work is easy to grasp, and order of accuarcy is higher.

And for half logical, promptly do not mill logical sheet material, can be divided into two kinds of situations again, promptly respectively on sheet material milling go out straight line or curve.For first kind of situation, because the figure line of milling is a straight line, only the incipient stage need locate sheet material by the detent mechanism on the workbench, will not need the operator to aim at sheet material artificially in the then whole milling process, and institute still can use in the above described manner.And for second kind of situation, aforesaid way then should not use, because sheet material can cover in milling head, and makes milling head invisible, can make the operator can't know the position of milling head like this, causes the degree of accuracy to be difficult to grasp.

For this reason, industry then uses the formula bakelite of being absorbed in to mill to carry out half logical milling, and this mode normally is fixed on sheet material on the workbench, and the hand-held bakelite of operator mills, and moves bakelite according to the figure line on the sheet material and mills and carry out.

In addition, in whole process, owing to use the particularity of sheet material, promptly need on sheet material, obtain the figure line so that follow-up milling, the comparatively general way that industry adopts is directly manual drawing or printing figure line on sheet material, but attractive in appearance for sheet material, and the improper figure line that on sheet material, obtains by this way sometimes.Therefore also have a kind of by projection imaging to prepare the method for sheet material, promptly on plate surface to be processed, apply photosensitive material, for example silver bromide then is projected in the manuscript line on the sheet material by projector.At this moment, photosensitive material is subjected to understanding the variation that produces on the color after the light irradiation, thereby shows the manuscript line on sheet material.By this way, can not influence in preparation that it is attractive in appearance in the sheet material.It should be noted that formed figure line just in time is opposite with the figure line that last milling goes out.

To sum up, mill in the process that sheet material is processed, still have its inconvenience by bakelite.At first, the preparation of the last figure line of sheet material and the milling of sheet material are two relatively independent steps, and each step all need be undertaken by different equipment, waste time and energy, and the cost height.Secondly, sheet material is being carried out half logical, when promptly not milling logical curve milling, milling because the scope of application that bakelite mills only limits to be absorbed in the formula bakelite, the selection that the operator is milled bakelite has certain restriction.

The above-mentioned structure that is Woodworking tool worktable of the present invention is formed, and it sees also Fig. 5 to Fig. 7 when sheet material workpiece is carried out milling, is example with the manual drawing line of publishing picture here, and the figure line of drawing out on sheet material 4 has center line X.Operator's pivotal support arm 24, and open laser indication device 25 and launch laser projection, the indication by light beam 26 makes laser indication device 25 aim at milling head 31.At this moment, the sheet material 4 that will have the figure line is placed on the platen 2, owing to need sheet material 4 such as is passed at operation, locatees the baffle plate 21 and the angle gauge 22 of sheet material so can remove being used on the platen 2 here.Light beam 26 drops on the visible face of sheet material 4, and is formed with subpoint 28, and the operator moves sheet material 4, and subpoint 28 is positioned on the center line X of described figure line, has promptly located the initial position of milling.Then, the depth location that the operator promotes milling head 31 begins milling, in the whole process, because subpoint 28 can clearly indicate the position that the bakelite that is hidden by sheet material 4 mills 3 milling head 31, the operator fully can be according to the indication of described subpoint 28, pass sheet material 4, and subpoint 28 is positioned on the center line X of figure line all the time, can finish milling.At last, support arm 24 is gone back to initial position, then can discharge the space of Woodworking tool worktable top, so that other application.

But, in aforesaid way, the operator is to be reference with the center line X that schemes line always, certainly, the operator also can be with the edge line of scheming line as reference, and but, these all are not easy to the operator and accurately grasp, so before carrying out milling, the adjusting that can also carry out on the diameter subpoint 28, promptly the operator rotates adjusting knob 27, light beam 26 overstriking or attenuate thereupon, think that until the operator width of the diameter of subpoint 28 and the figure line on the sheet material 4 is suitable, can stop to regulate.Like this, in the process of using, can avoid because of subpoint 28 excessive or too small disalignment X or edge lines, and make the milling of sheet material error occur, thus the degree of accuracy of raising milling.

In above-mentioned description as most preferred embodiment, laser indication device 25 is to be installed in straight down on the slide block 243, thereby launch light beam 26 straight down, this mode can solve the problem of laser alignment comparatively simply, is applicable to the operation that accuracy is higher.And for the less demanding situation of accuracy, see also Fig. 8 to Fig. 9, disclosed second embodiment of Woodworking tool worktable of the present invention, be with the first embodiment difference, the support arm 24 ' that is arranged on platen 2 one sides is a upright arm, its end removably connects as one with platen 2, and its free end is provided with a runing rest 50 that is used to install laser indication device 25, this runing rest 50 comprises rotating shaft 51 and dial 52, laser indication device 25 is installed in dial 52 medial surfaces, and the direction of milling 3 milling head 31 towards bakelite, this position is the initial position of laser indication device 25, just the zero graduation position of dial 52.On this position, laser indication device 25 is A with the horizontal range of milling head 31, and vertical range is B, and laser indication device 25 is α with horizontal angle, and then above-mentioned value constitutes the tan pass and is:

tgα＝B/A

After having placed thickness on the platen 2 and being the sheet material 4 of b, then need to rotate runing rest 50, make laser indication device 25 and horizontal angle α be reduced to β, the tan of angle beta closed and was this moment:

tgβ＝(B-b)/A

So, the angle that swinging mounting 50 rotates should for:

θ＝α-β＝arctg(B/A)-arctg(B-b)/A

Like this, the sheet material 4 of corresponding different-thickness is then set up the corresponding relation of thickness b and rotational angle θ, this corresponding relation is shown with scale on dial 52, so, when the sheet material of milling different-thickness, only need sheet material measurement thickness, then according to value, rotate runing rest 50, laser indication device 25 can be raised, make the light beam of launching 26 be projected in the position that subpoint 28 on the sheet material 4 correctly indicates milling head 31, that is to say that the subpoint 28 of this moment is positioned on the axis Y.

In a second embodiment, because support arm is redesigned, shorten even removed horizontal arm, use thereby the upper space that has discharged workbench is beneficial to his.

See also Figure 10, disclosed the 3rd embodiment of Woodworking tool worktable of the present invention, be, at the free end of the slide block 243 of support arm 24 with the first embodiment difference, be provided with a rubber-like vertical line 60 straight down, it can the flexible and location of in the vertical direction.Vertical line 60 is connected with an indicator collet 61 with circular cone tip 62, does not do the time spent when indicator collet 61 is not subjected to external force in the horizontal direction, relies on self gravitation, and circular cone tip 62 will be straight down, thereby play the effect of indication, promptly as the indication end of indicating device.Operator's rotational support arm 24, and the position of adjusting slider 243 on horizontal arm 242 make circular cone tip 62 point to milling head 31, the position of indicator collet 61 with milling head 31 can be mapped.At this moment, sheet material 4 is placed on the platen 2, indicator collet 61 will indicate the position that the bakelite that is hidden by sheet material 4 mills 3 milling head 31 again.Because above-mentioned position corresponding relation is so circular cone tip 62 is positioned on the axis Y.It should be noted that in use indicator collet 61 can not contact with sheet material 4, otherwise, will make indicator collet 61 be subjected to frictional force to produce mobile and cause to indicate to lose efficacy, so, the operator in use, the vertical line 60 that stretches downwards gets final product indicator collet 61 as far as possible near sheet material 4.

In the 3rd embodiment, substituted the higher laser indication device of cost with simple and practical vertical line and indicator collet, save manufacturing cost and can reach indicating effect equally.

By adopting above-mentioned Woodworking tool worktable, sheet material is being carried out half logical, when promptly not milling logical curve milling, originally needing to avoid fixed plate, the drawback of the mode milling workpiece that the operator mills with hand-held bakelite, the operator only need be absorbed in mobile sheet material can easily finish milling work.

In order to help operator's use more, Woodworking tool worktable of the present invention comprises a projection arrangement, and can realize the preparation of the last figure line of sheet material with projection imaging.See also Figure 11 to Figure 12, but this projection arrangement comprises the motherboard 72 and the photosensitive material 73 of a light source 71 hollow outs, wherein, light source 71 is specially a spotlight, can be installed on the support arm 24,24 '; Motherboard 72 is a lighttight plate, and the operator is the hollow out line of publishing picture thereon, please together consults Figure 12, is then formed hollow-out parts 721 by the part of hollow out on the motherboard 72, allows the light of light source 71 to inject; And photosensitive material 73 is industry silver bromide or an equivalent material commonly used.

During use, the figure line that the operator at first goes out to need with hollow out on the motherboard 72 then places it on the sheet material 4 that is coated with photosensitive material 73, and three's position concerns as shown in figure 13.At this moment, the photosensitive material 73 that is positioned at hollow-out parts 721 positions on the motherboard 72 exposes.After light source 71 was opened, its light was radiated on the motherboard 72, and under the effect of light, the photosensitive material 73 of exposed parts can produce chemical reactions and cause variation on the color.Continue for some time, after promptly chemical reaction fully acts on, close light source 71, and take off motherboard 72, then be formed with clear and legible figure line on the sheet material 4.Like this, sheet material 4 to be processed promptly prepares and finishes, and then can carry out follow-up milling work.
