The specific embodiment
Followingly describe with regard to embodiments of the present invention with reference to accompanying drawing.
Fig. 1 is a kind of embodiment of circular saw guider of the present invention to Figure 13.
As shown in figure 1 to figure 13, circular saw guider 10 of the present invention is (with reference to Figure 12) when being placed on machined object 1 such as plasterboard on the machine table (unmarked in the accompanying drawing), hard board, cement plate in 5 cuttings of electronic circular saw, is positioned in the device that guiding is provided on these machined objects 1, to electronic circular saw 5.That is to say that electronic circular saw 5 is to be placed on the machined object 1, cuts machined object 1 by the guiding of circular saw guider 10.
This circular saw guider 10, as shown in Figures 1 and 2, having to electronic circular saw 5 provides the elongate guide plate 11 of guiding and with the door handle device 20 that screw 12 is connected the side of guide plate 11 is installed.
The guide plate 11 that is positioned on the machined object has the directed side 11a that guiding is provided to electronic circular saw 5.
In addition, door handle device 20 have be positioned on the machined object chiral substrate 21 and on the chiral substrate 21 by pair of posts 24a, elongate lever 23 that 24b was supporting, and lever 23 is from leading section 23a end (base end part) 23b extension backward.
If for the area of control handle substrate 21, make its miniaturization and with lever 23 be arranged on guide plate 11 near, when blocking operation, probably can make the part of the motor of electronic circular saw 5 run into lever 23.For another fruit lever 23 and guide plate 11 are be arranged in parallel,, thereby can not cosily operate because of the angle problem of arm can increase burden to the operator.Therefore lever 23 be set at from guide plate have suitable distance and and guide plate 11 between on the angled position.
Moreover, fixing the bottom surface of chiral substrate 21 by securing members such as rivet 33, be provided with butt body 30 (with reference to Figure 11).Thereby this butt body 30 is arranged to extend to the position of determining circular saw guider 10 with the side 1a of guide plate 11 right angle intersections that are the elongate prolongation and butt machined object 1.
Below, describe in detail with regard to guide plate 11 according to Fig. 1, Fig. 2 and Fig. 6 a, Fig. 6 b.Shown in Fig. 1, Fig. 2 and Fig. 6 a, Fig. 6 b, guide plate 11 is by screw 12 and door handle device 20 chiral substrate 21 is connected is installed.This guide plate 11 is as indicated above by the directed side 11a of guiding being provided for electronic circular saw 5 and comprising that a pair of ducted body with inner space 19 forms.
The 19 rectangular cross sections, inner space of directed side 11a side wherein, in addition, directed side 11a be provided with abreast up and down the electronic circular saw 5 of butt, with the line contact to electronic circular saw 5 provide guiding, the cross section is a pair of pole 13 (with reference to Fig. 6 b) of circle shape.Shown in Fig. 6 b, each pole 13 is embedded in from the surface 17 of the directed side 11a of guide plate 11 position of direction to the inside, and flatly stretches along the direction of the length of guide plate 11.Because the axle center of each pole 13 is positioned at the inboard on the surface of directed side 11a, although so each pole 13 surface 17 of exposing directed side 11a, still can be securely fixed in safely on the directed side 11a.
Also can consider pole 13 to be fixed on the surface 17 of directed side 11a of guide plate 11 with adhesive etc.But with adhesive pole 13 is fixed on the surface 17 of directed side 11a, pole 13 may come off from directed side 11a in the operation; In addition, also it is contemplated that need not electronic radial arm saw 5, and carries out some easy rupturing operations with cutleries such as parting tools, at this moment if with the words of adhesive, in case it is contemplated that operate miss cutlery has been inserted between directed side 11a and the pole 13, will peel off.
But according to the present invention, pole 13 is the inside that is embedded in directed side 11a, and the position in the axle center of pole is in the inboard on the surface of directed side 11a, so can make each pole safety and positively be fixed on the directed side 11a.
The radical of pole 13 can be one, also can be several.Can be that the excellent 13a or the cross section of triangular shape is that dimetric excellent 13b replaces pole 13 also in addition with the cross section.(Fig. 6 c).Moreover it is that flat excellent 13c is to replace pole 13 that the cross section is set on directed side 11a.These cross sections are that dimetric excellent 13b in excellent 13a, the cross section of triangular shape or cross section are that flat excellent 13c can be provided with one or be provided with several.
In addition, above-mentioned guide plate 11 is that the ducted body two ends formed, guide plate with a pair of inner space 19 are provided with end cap 16, and the inner space 19 of guide plate 11 is sealed by end cap 16.
In addition, material as the guide plate 11 that forms by ducted body, the continuously shaped extruded aluminum of general use, but only aluminium is pressed the words that Len req cuts off, sharp section may hook be stumbled and is arranged on the flexible pipe of the vacuum cleaner on the radial arm saw or makes it damaged, and end cap 16 also can be to the preventive effect that has of this situation.
Like this, by a pair of pole 13 that guiding is provided to electronic radial arm saw 5 that contacts with line is set on the directed side 11a of guide plate 11, can make and make electronic radial arm saw 5 when guide plate 11 moves, it is littler that guide plate 11 acts on the frictional force that is produced when friction comparison on the electronic circular saw 5 is led to electronic radial arm saw 5 with face contact, can improve the operating efficiency when carrying out rupturing operation with electronic circular saw 5 thus.
Because general electronic circular saw 5 is heavier, and be positioned on the machined object 1 and move along guide plate 11, so electronic circular saw can lateral inclination in moving, so also a pole 13 can be set at the directed side 11a of guide plate 11, electronic circular saw 5 be led by the mode of this root pole 13 with a contact.
Then door handle device 20 is described in detail according to Fig. 1, Fig. 2, Fig. 7 a, Fig. 7 b and Fig. 8 a, Fig. 8 b.Shown in Fig. 1, Fig. 2, Fig. 7 a, Fig. 7 b and Fig. 8 a, Fig. 8 b, door handle device 20 have be positioned on the machined object chiral substrate 21 with the lever 23 by a pair of pillar 24a, elongate that 24b is supporting on the chiral substrate 21.Chiral substrate 21 is provided with three opening 21a, and distolateral thereafter (base end side) is provided with butt joint acknowledgement window 22.
And lever 23 has leading section 23a and distolateral backward (base end side) that the forward end side direction exceeds front pillar 24a and exceeds the rearward end 23b of rear end side pillar 24b and the central portion 23c of pair of posts 24a, 24b.
In addition, shown in Fig. 7 a, Fig. 7 b and Fig. 8 a, Fig. 8 b, in the middle of the pair of posts 24a, the 24b that support lever 23, the pillar 24a of front comes highly than the height of the pillar 24b of rear end side, and lever 23 is settled to be rising sample attitude from rearward end 23b forward end 23a for this reason.
In addition, lever 23 is formed by ducted body, and this ducted body has a pair of laterally side by side cylindric inner space 25, and its surface 28 is through asperities processing, so can be easily and positively hold lever.
Still, as indicated above, because being rising sample attitude from rearward end 23b forward end 23a, settles lever 23, so the operator who uses 5 pairs of machined objects of electronic circular saw to cut needn't hold lever 23 by forward lean, can hold lever 23 on one side with stable attitude, Yi Bian electronic circular saw 5 is moved along circular saw guider 10.
Moreover lever 23 has from the side-prominent leading section 23a of pillar 24a forward end, reaches, from the side-prominent to the back-end rearward end 24b of pillar 24b.So the operator needn't only control the central portion 23c between pillar 24a and the 24b, also can control leading section 23a or rearward end 23b.
Shown in Figure 14 a～Figure 14 e, also can be on the position of pillar 24a, the 24b of lever 23, from the angle of overlooking make its crooked to the left or to the right be certain angle (with reference to Figure 14 a), also can be on the position of pillar 24a, 24b be certain angle (with reference to Figure 14 b) with lever is crooked up and down.
Again, also the shape of the leading section 23a of lever 23 or rearward end 23b can be made glomeration (with reference to Figure 14 c, maybe will exceed the leading section warpage of straight line portion of the prolongation of pillar 24a or 24b, all looks lever to be L shape (with reference to Figure 14 d) or to make lever 23 all be T word shape (with reference to Figure 14 e) and also can.
Again, the shape of the central portion 23c of lever 23 also is not limited to straight line, can be arciform bending or contrary flexure shape.
Again, shown in Fig. 8 a, Fig. 8 b, door handle device 20 the bottom surface of the part corresponding of chiral substrate 21 with pillar 24a, 24b, respectively be provided with concavity portion 27, and having the installation screw to insert from concavity portion 27 sides chiral substrate 21, pillar 24a, 24b just are fixed on the chiral substrate 21 by screw 26 is installed.Screw 26 is installed to be run through chiral substrate 21 through pillar 24a, 24b.In addition, the head 26a that screw 26 is installed is rested in the concavity portion 27 of chiral substrate 21, and in this concavity portion 27, the head 26a of screw 26 cover to be installed, be embedded in that rubber slabs 25 play anti-skidding effect in the concavity portion 27 between chiral substrate 21 and machined object 1.
Like this because the bottom surface of the part corresponding with pillar 24a, 24b of chiral substrate 21 is being provided with concavity portion 27, and in this concavity portion 27, insert installation screw 26, and embedding rubber slab 25, when cutting off machined object 1 with electronic radial arm saw, during the downward application of force of the lever 23 of the hand-held door handle device 20 of operator, directly transmit to each pillar 24a, 24b and chiral substrate 21 by lever 23 to rubber slab 25 from operator's downforce.Can impose powerful pressure by 25 pairs of machined objects 1 of rubber slab for this reason, thereby increase the frictional force between rubber slab 25 and the machined object 1, make rubber slab 25 bring into play higher anti-skidding effect at machined object 1 with between chiral substrate 21.
But,, be easy to generate when being placed in guide plate 11 on the machined object 1 and rock and diminish stable if the thickness of rubber slab 25 is extremely thick.
The thickness setting that therefore will be arranged on the rubber slab 25 of concavity portion 27 is advisable at the thickness with the minimum that can obtain skidproof effect.
The shape of rubber slab 25 and concavity portion 27 is not limited to circle, and the corresponding part of head 26a with screw 26 is installed in the middle of the rubber slab 25 can be dug up, and makes rubber slab 25 be the shape of Deep-fried doughnut.Like this, just in case the installation screw 26 of lever 23 is loosening, it can be tightened again.
Said structure constitutes the radial arm saw guider 10 with higher skidproof effect.But also following situation can appear: when wanting to move the position on machined object, owing to anti-skidding effect is crossed by force and can't be slided, and work can't be carried out smoothly, or leave a trace on machined object owing to the friction of rubber slab.
Do not do diagram at this, only do explanation.Similar above-mentioned situation can be provided with latch plate at the place of number, bottom chiral substrate 21 of radial arm saw guider 10 and make a chiral substrate 21 little floating, and hand-held then lever 23 is from pressing.Latch plate bends in pressure, and anti-skidding rubber slab 25 contacts with machined object 1, reaches to bring into play to prevent the effect that departs from; Perhaps will tongue be set to the perforation of the part of chiral substrate 21, make it to have the effect of latch plate.
Just be located at below the butt body 30 of the bottom surface of chiral substrate 21 is done explanation.
As Fig. 1, Fig. 2, Figure 10 and shown in Figure 11, butt body 30 by rivet 33 tipping the bottom surface of chiral substrate 21, this butt body 30 be guide plate 11 (guide direction of guide plate 11) right angle intersection and the extension that elongate is extended.As shown in figure 11, butt body 30 by, be provided with the head that makes rivet 33 and bury the ducted body of being formed, be formed with the square-section in the upper plate 30a of wherein depressed part and lower plate 30b and pair of side plates 30c.
And be used to the side 1a of butt machined object 1 at a side's of butt body 30 side plate 30c, in order to determine the position of circular saw guider 10.The upper plate 30a of butt body 30 with the bottom surface butt of chiral substrate 21, in butt body 30 inside, dispose the upper plate 30a of perforation butt body 30 and upper plate 30a is fixed on the rivet on the bottom surface of chiral substrate 21 33 (seeing Figure 11).
In Figure 11, the position of the head of rivet 33 is in the inside of butt body 30; And being provided with in the butt body 30 can be along wooden 15 (aftermentioned) of substituting of butt body 30 activities, and the opposing party's of low junctor 30 side plate 30c is provided with the hold-down screw 32 that fixedly substitutes wood 15 in butt body 30.
As shown in figure 11, butt body 30 is fixed on upper plate 30a the bottom surface of chiral substrate 21 the bottom surface of chiral substrate 21 and by the rivet 33 that is arranged in the butt body by upper plate 30a butt, thereby butt body 30 directly can be fixed on the bottom surface of chiral substrate 21.For instance, comparison is provided with the mounting flange of expansion laterally and by this mounting flange the butt body is fixed on the mode of the bottom surface of chiral substrate 21 on butt body 30, the manner can more positively be fixed on butt body 30 the ground of chiral substrate 21, and butt body 30 can not be out of shape in operation yet.
In addition, also can connect with screw, welding, pallet, mode such as bonding replace rivet 33 that butt body 30 is fixed on the bottom surface of chiral substrate 21.
Perhaps, also can and substitute wood 15 with butt body 30 is provided with respectively.That is to say to be set up in parallel two ducted bodies with square-section, one as butt body 30, another is as substituting wood 15 maintenance body and it being played a role on the position that separates with butt body 30.Again owing to have to keep bodies separately to be provided with in addition in the wood 15 that substitutes of ducted body, so low junctor 30 can constitute with the higher pure square bar of intensity, even can be only with square bar as low junctor 30.Substitute wooden 15 maintenance body for not using the user who substitutes wood 15 to be provided with.
In machined object, have the material that similar side material, cross section are not rectangle merely sometimes.In this case, if the correctly phenomenon of the end face of butt machined object 1 of butt body 30 can appear in the thinner thickness of butt body 30.So consider under the complicated prerequisite of the cross section possibility of machined object, the thickness of butt body 30 can be made thicker than machined object 1.
But the thickness of butt body 30 is littler than machined object 1.Even for this reason the machined object 1 of plural number is stacked and the superiors' machined object 1 utilization circular saw guider 10 cut off operation in, the machined object 1 of 30 butt the superiors of butt body provides the location of circular saw guider 10, can prevent that thus butt body 30 butts are positioned at the machined object 1 below the superiors' machined object 1, thereby provide the position of incorrect radial arm saw guider 10.
As Figure 12 and shown in Figure 13, that the rearward end of guide plate 11 is provided with is outstanding towards the side of directed side 11a, allow electronic disk apart from 5 abeyant temporary backings 35.Temporary backing 35 is arranged on the rearward end of guide plate 11, can be capable of expansion and contraction to the side.Can make temporary backing 35 project to Len req from the rearward end of guide plate 11, with screw 36 temporary backing 35 is fixed on the guide plate 11 then.
The purpose that temporary backing 35 is set in the rearward end of guide plate 11 is like this, when as cutting off the fine finishining material, need cautiously selecting off-position, electronic circular saw 5 is shelved on the temporary backing 35, so just can easily adjust angle, determine the position of electronic circular saw 5 with respect to guide plate 11 by watching point of a knife attentively.
When roughing etc. does not need cautiously to determine the position, because do not need temporary backing 35, so can be with fixing with screw 36 removal in the lump.
Again, door handle device 20 chiral substrate 21, low connect portion 30 is provided with the terminal of expression shearing length A, B on the guide direction of guide plate 11 mark 29.
Below just describe by the mode of the enforcement that foregoing constituted.
At first as shown in Figure 3, machined object 1 is placed on the machine table, then circular saw guider 10 be placed in machined object 1 above.
Secondly, will be located at, determine the position of disk guider 10 on machined object 1 then the side 1a of the side plate 30c butt machined object 1 of the butt body 30 of the bottom surface of chiral substrate 21.
Can confirm inclination between butt bodies 30 and the machined object 1 to the butt joint acknowledgement window on the chiral substrate 21 22 this moment by being located at, the side 30c that can confirm butt body 30 thus whether correctly butt machined object 1 side 1a and confirm by this whether lead 10 position of circular saw correct.
As shown in Figure 4, substitute wood 15 and in butt body 30, extracted out certain-length in advance, and the screw 32 that is fixed is fixed on butt body 30 inside to foreign side.In addition, as shown in figure 13, temporary backing 35 is also extracted out Len req by the rearward end from guide plate 11, and the screw 36 that is fixed is fixed on the guide plate 11.
Secondly shown in Fig. 5 a, electronic circular saw 5 is positioned on the temporary backing 35 that is arranged on the guide plate 11, and electronic then circular saw 5 moves along the directed side 11a of guide plate 11, so substitute wood 15 and machined object 1 is cut off by electronic circular saw 5.Electronic like this circular saw 5 is at first to be positioned on the temporary backing 35, just move then along the directed side of guide plate 11, so can be after the selected tram of electronic circular saw 5 with respect to guide plate 11, provide correct guiding to electronic disk 5, electronic circular saw 5 is moved along the directed side 11a of guide plate 11.
Substituted wood 15 and machined object 1 according to what electronic circular saw 5 cut off, can determine the initial cut-out edge of machined object 1.In addition, the outstanding length that substitutes wood 15 is corresponding to the length between the cut-out knife edge of the directed side 11a of guide plate 11 and electronic circular saw 5.For this reason, when carrying out subsequent processing, only need the line 2 on the front end aligning machined object that substitutes wood 15 of circular saw guider 10 just can be determined the tram (with reference to Fig. 5 b) of the circular saw guider 10 on machined object 1 by this.
Then, shown in Fig. 5 b,, electronic circular saw 5 is placed on the temporary backing 35 of circular saw guider 10, electronic circular saw 5 is moved along the directed side 11a of guide plate 11 with last time identical.Electronic like this circular saw just can accurately accurately cut off machined object 1 along line 2.
During this period, 23 pairs of the levers of the hand-held door handle device 20 of operator press chiral substrate 21.
At this moment, because being rising sample attitude from rearward end 23b forward end 23a, settles lever 23, hold lever 23 so use operator that 5 pairs of machined objects 1 of electronic circular saw cut needn't body to lean forward, can hold lever 23 on one side with stable attitude, Yi Bian electronic circular saw 5 is moved along circular saw guider 10.
Again, because the bottom surface of the part corresponding with pillar 24a, 24b of chiral substrate 21 is being provided with concavity portion 27, and in this concavity portion 27, inserted installation screw 26 and embedded rubber slab 25, so when cutting off machined object 1 during the downward application of force of the lever 23 of the hand-held door handle device 20 of operator, be directly passed to rubber slab 25 by lever 23 by each pillar 24a, 24b and chiral substrate 21 from operator's downforce with electronic radial arm saw.Can make rubber slab 25 give machined object 1 for this reason, thereby increase the frictional force between rubber slab 25 and the machined object 1, make rubber slab 25 bring into play higher anti-skidding effect at machined object 1 with between chiral substrate 21 with powerful pressure.
Moreover, by a pair of pole 13 that guiding is provided to electronic radial arm saw that contacts with line is set on the directed side 11a of guide plate 11, can make and make electronic radial arm saw 5 when guide plate 11 moves, it is littler that guide plate 11 acts on the frictional force that mode was produced that the friction comparison on the electronic circular saw leads to electronic circular saw 5 with face contact, can improve the operating efficiency when carrying out cutting operation with electronic circular saw 5 thus.
Again, door handle device 20 chiral substrate 21 on, be provided with mark 29a, the 29b of the terminal of expression shearing length A, B to the guide direction of guide plate 11 from low junctor 30.In addition, be provided with the terminal label 29c of the length C that expression begins from the directed side 11a of guide plate 11 on chiral substrate 21.
For this reason, the operator can be according to cutting off mark 29a, 29b, 29c know shearing length A, B, C in cutting off operation terminal.For the terminal of knowing shearing length A, B, C there is no need to be provided with other special scale marks.
Specifically, will cut off mark 29c and be arranged on position, cut off apart from directed side 11a 303 millimeters (C) mark 29a be arranged on butt body 30 be starting point 303 millimeters (A) the position, cutting off mark 29b, to be arranged on from the position that butt body 30 begins 455 millimeters (B) serve as effective.
Cut off when mark 29a and 29c can be used in the glued board bookbinding on rafter wood and delimit the operation of dimension line, cut off mark 29b and can be used for plasterboard delimited in the operation of dimension line when cutting.
