Abstract
In a jig saw equipped with a reciprocally driven saw body and stripe pieces 34, 74 coinciding with the saw body 28, a guide means obstructing the jamming of the saw body in a cutting passage is provided in order to guide the saw body 28 in the cutting passage cut by a saw and the stripe piece 34 is arranged so as to be resolvable centering around the revolving axial line parallel to the saw body in order to obstruct jamming and, in this case, especially, curvature of the cutting passage to be formed as the guide means.
Description
The present invention relates to a kind of carving hole saw.
DE-OS 4104296 discloses the carving hole saw of described type.This saw under substrate, have one with saw blade side by side, be installed in the laminar bracing element on the housing.This bracing element be used for supporting can move along bracing element, transfer to the second parallel substrate earlier.Substrate is fastened on the bracing element.This bracing element is mainly used to support second substrate, and both have formed the big impost of carving hole saw jointly.Do not need the bracing element and second substrate in addition and when working, the removal cost of these parts is higher.
In addition, bracing element is excessive with the parallel distance of carving hole saw, and this is unfavorable for having the sawing of small curvature radius cutting profile, because bracing element may be clipped in the crooked cutting channel.
According to the present invention, a kind of carving hole saw is provided, have a saw blade that moves back and forth and one that be arranged side by side with saw blade, at the bracing element of saw blade back, it is characterized in that, but this bracing element opposing parallel is provided with in the balance staff swing of saw blade.
By contrast, the advantage of carving hole saw of the present invention is, and is in light weight, easy to operate, convenient disassembly.The bending cutting of using carving hole saw of the present invention to be beneficial to especially in addition to finish small curvature radius.Outstanding advantage is, without other aid just can be repeatedly repeatedly sawing go out more accurate circular contour.
Further describe the embodiment of the invention with reference to the accompanying drawings.
Fig. 1 is a carving hole saw side view of the present invention;
Fig. 2 is the enlarged drawing of Fig. 1 saw blade part;
Fig. 3 is the sectional view of bracing element and saw blade among Fig. 2;
Fig. 4 is the view when transferring to small curvature radius shown in Figure 3;
Fig. 5 is the sectional view of the bracing element embodiment of band leg;
Fig. 6 is the perspective view of Fig. 5 structure.
Carving hole saw 10 shown in Figure 1 has a motor casing 12 as handle, and this motor casing has switch 14, and is connected with gear mechanism housing 16 flanges, and an auxiliary handle that makes progress 18 is arranged on the gear mechanism housing 16.20 of gear mechanism housing 16 and substrates are provided with a hinge (schematically showing).This carving hole saw 10 is bearing on the workpiece 24 by substrate 20.Saw blade 28 vertically downward passes the open-work 26 on the substrate 20, the back of this saw blade 28 abuts against guiding ball 32, behind saw blade, be provided with one rise the support wedging action, with saw blade 28 side by side with parallel bracing element 34, it has prevented saw blade 28 mounting boards and tilt phenomenon in sawing process.
Fig. 2 is the cross section enlarged drawing of Fig. 1, is depicted as the transmission device and the housing 16 of the elevating lever 36 of band supporting saw blade 28.In addition, guiding ball 32 has the axis of rolling 33, and flank 27 has the tooth 29 of saw blade 28.
Clearly visible from Fig. 2 in addition, bracing element 34 as pocket blade is swung along the direction of arrow 39 relative pivots 38 in saw blade 28 planes, when therefore bracing element 34 does not use, can put the outermost swing position place of direction of observation, parallel with the axle of motor casing 12 to the right and rest in the locating slot 40 of gear mechanism housing 16 of substrate 20 tops (not further describing).
In addition, bracing element 34 can be provided with around 42 swings of parallel axes balance staff by relative saw blade 28 as the rudder of aircraft vertical tail.
Figure 3 shows that total cross section of saw blade 28 and bracing element 34, the rudder structure of bracing element 34 can separate with saw blade 28 and leave the swinging axle 42 that is parallel to the saw blade axis, and the cross section of bracing element 34 is gradually little on 35 directions of bracing element rear portion.
Figure 4 shows that the structure that is used for curvilinear cut among Fig. 3.At this, the swinging axle 42 relative saw blades 28 of bracing element 34 have a pivot angle α, so that make saw blade 28 form crooked cutting channel, or have determined the radius of curvature of cutting channel.
The sawing process of carving hole saw 10 is as follows: the hand switch 14 of drive motors (not shown), and the elevating lever 36 that has saw blade 28 is moved around, the substrate 20 of carving hole saw 10 so is set, so that tooth 29 side cut of saw blade 28 are advanced in the workpiece 24 on workpiece 24.Because move the chicken tail 10 parallel with workpiece on sawtooth 29 directions, sawing goes out cutting channel on workpiece 24, saw blade 28 and bracing element 34 backs are protruding subsequently.
During straight cuts, the bracing element 34 of position shown in Figure 3 has prevented the excessive swing of carving hole saw 10 around the saw blade longitudinal axis.Because the setting of bracing element 34, straight cuts can be in line basically or off-straight hardly.
After the swing of bracing element 34 relative balance staffs 42 was locked, saw blade 28 and bracing element 34 be fixed-site each other, just made corresponding cutting profile in the arc-shaped substantially without clamp or similar aid.The adjustment of angle can make the cutting radius of curvature become big or diminish, and radius of curvature diminished when promptly pivot angle was big, and pivot angle hour radius of curvature becomes big.
Figure 5 shows that carving hole saw 10 bottoms, partly cut-away be used for the not U-shaped suspension bracket 75 of the bracing element 74 of bands for band.The through hole 66 of substrate 60 is for saw blade (not shown), bracing element 74 with suspension bracket 75 common settings of two vertical leg 76,77, and leg is as by welding or be spirally connected and link to each other with the gear mechanism housing (not shown) of saw blade.
Connect with two legs 76,77 and the cross member 78 parallel with substrate 60 by a hole 81 supporting bracing elements 74, it is fixing by turn 84 (Fig. 6) that the thread bush 83 of bracing element 74 passes hole 81.Swinging axle 82 swings shown in the line of bracing element 74 corresponding points.
The width of the through hole 66 of substrate 60 is wanted suspension bracket 75 is put in, when suspension bracket 75 is placed on the workpiece, the bottom side of the bottom side of suspension bracket part 78 and substrate 60 at grade, on the balance staff 82 stretched be the symmetry axis or the transverse axis of guiding ball 72 simultaneously, guiding ball 72 opposing parallel are in axle 73 rotatably supports of substrate 60, guiding ball 72 has V-shape annular groove, annular groove supporting saw blade back (not shown).
Carving hole saw belt substrate 60, unshowned is consistent with the carving hole saw among above-mentioned Fig. 1 in principle.
Figure 6 shows that the three-dimensional enlarged drawing of the anchor clamps of bracing element 74, fixedly U-shape suspension bracket 75 like this on carving hole saw gear mechanism housing (not shown), U-shaped leg 76,77 is parallel to bracing element 74, and the plane of structure that connects U-shaped leg 76,77 is parallel to substrate 60.On balance staff 82 and line direction, passed hole 81 on suspension bracket 75 cross members 78 as the axle sleeve 83 of bracing element 74 convex shoulders.By turn 84 fixed hubs and bracing element 74, prevent that it from 81 coming off from the hole.
The unshowned carving hole saw of belt substrate 60 is basic consistent with the carving hole saw of Fig. 1.
Fig. 5,6 device that bracing element 74 is returned shown in 2 of not drawing.
Can be provided with the suspension bracket of parallel with roller bearing relatively axis swing among the unaccounted embodiment of the present invention.Can make the bracing element pendulum get back to the position parallel thus as required, and not have to carry out sawing under the bracing element with substrate.Bracing element is put to blade direction, so that bracing element is on the pinnacle as the supporting of the bracing element lower end in guide rail saw blade back.
