DESCRIPTION OF SPECIFIC EMBODIMENTS The present invention will now be described in more detail with reference to the accompanying drawings in which the same parts are indicated by the same reference numerals.
FIG. 1 shows a boring machine with a magnetic base board consisting of a main body 101, and a verticallymovable member 102 which is movably located on the front side of the said main body. Aportable boring machine 103 provided with adrill 106 is connected to the said vertically movable member by supportingarms handle 107 is pivoted to a side of the main body 101 to move vertically the movable member As shown in FIG. 1, the boring machine withmagnetic board 110 is placed on thesurface 112 of the material 111 to be perforated. Thelight projector 113 is adjusted in such a way that the projected light Y from thelight projector 113 will focus at a point where an extension line of the center of thedrill 106 carried on theboring machine 103 intersects thesurface 112 of the material 111 to be perforated. As shown in FIG. 2, this is effected by moving thehousing 122 of thelight projector 113 and screwing or loosening theregulation cap 125. Then the boring machine with a magnetic board is moved so that the focus 2 of the projected lightY may be adjusted to be projected on the punch mark P provided on thesurface 112 of the material to be perforated. When the focus Z is adjusted to the punch mark P, electric current is supplied to themagnetic board 110 to magnetize the same and theboring machine 103 is fixed to the material to be perforated.
In this way, centering is very easily conducted, and such repeated centering operations as are required in prior methods according to which the end of thedrill 106 is brought close to the punch mark P by means of thehandle 107 become unnecessary.
The boring machine with a magnetic board shown in FIGS. 1 and 2 must be moved on the surface of the material to be perforated l 1 1 for the purpose of centering. On the other hand, in order to conduct centering with a floor boring machine as shown in FIG. 10, thematerial 133 to be perforated is clamped by a vice 132 provided on a table 131 and is moved so that the focus Z of projected light Y is aligned with a punch mark to be perforated onmaterial 133. Thelight projector 113 is adjusted in advance in such a way that the projected light Y from thelight projector 113 will focus at a point where the extension line X of thedrill 106 intersects thesurface 134 of the material to be perforated 133. When the same material is to be perforated at many points in mass production, centering is easily con ducted by moving a material to be perforated in such a way that the focus 2 of the projected light Y is adjusted to various punch marks and thematerial 133 is clamped with the vice 132. Thus, with this boring machine, it is unnecessary even in mass production to repeatedly conduct centering at every punch mark by bringing the end of thedrill 106 close to the punch marks provided on the material to be perforated.
When the focus Z of the projected light Y is not perceptible because centering is conducted outdoors,
colored light may be effectively used as a projected light. Moreover, thelight projector 113 may be used as a common illumination device by removing theregulation cap 125 thereof.
As has been described so far, the present invention facilitates easy and rapid centering for perforation by adjusting a focus of the projected light from a light projector which is controlled properly in advance to a punch mark provided on the surface of a material to be perforated, instead of conventional operations for centering by repeatedly bringing the end of a drill close to a punch mark.
Any light projector may be used as a centering apparatus in the present invention. The light. projector shown in FIGS. 3 and 4 is fixed to the main body of a boring machine and adjusted in such a way that a projected light from the light projector will focus as a cross at a point where the extension line of the drill intersects the surface of a material to be perforated.
Thelight projector 141 shown in FIG. 3 comprises anelectric bulb 123 installed in ahousing 142. Amovable body 146 provided with a convex lens for condensinglight 143 and adisc 145 having an aperture in the shape of a cross is screwed to the inside of thehousing 142. A
regulatingcylinder 148 provided with aconvex lens 147 is located at the end of thehousing 142. The projected light Y may be adjusted to focus at a point where the extension line X of thedrill 106 intersects the surface of material to be perforated 111 and the precise adjustment of the position of focus Z is conducted by turning the regulatingcylinder 148. The aperture in the form of across 144 provided in thedisc 145 serves to make the focus Z of the projected light Y in a cross, which facilitates the adjustment of the focus to a punch mark provided on the surface of a material to be perforated.
When thedrill 106 of a boring machine is to be aligned with a punch mark P, the magnetic board 1 is moved to a proper position and fixed or the main body 101 which is provided with aboring machine 104 and mounted on themagnetic board 110 is adjusted, the magnetic board being left as it is. In either way the projected light Y is adjusted to the punch mark P.
In the rear part of thehousing 152 of thelight projector 151 shown in FIGS. 5 and 6,electric bulbs housing 152 further comprisesconvex lenses housing 152, projectingpieces convex lenses long slots partition wall 163 to divide the inside of thehousing 152. Theconvex lenses electric bulbs convex lenses pieces long slots housing 152 respectively, are movably pivoted to each other, any arbitrary pattern of focus of light is obtained by properly operating the projecting pieces and adjusting the images of filaments in arbitrary shapes.
The light projector shown in FIG. 7 facilitates the production of light and distinct focus patterns of light in the form of a cross with one electric bulb and an easy adjustment of the focus pattern.Light projector 171 comprises anelectric bulb 172 in which two crossedfilaments cylinder 176 provided with aconvex lens ad-. justably mounted at the end of thelight projector 171. As the light source is in the shape of a cross, a very distinct focus pattern in the shape of a cross is obtained, on a material to be perforated, by adjusting the light in thecylinder 176 provided withconvex lens 175 without reducing the intensity of radiation. Thus, a distinct and light focus pattern in the shape of a cross is easily obtained with this light projector by only focussing a cross image from the crossedfilaments electric bulb 172 with theconvex lens 175, which facilitates an efficient centering operation at such light places as the outdoors. Moreover, it is possible to make a light projector small-sized, because a number of lenses and electric bulbs are not required.
Any circuits may be used for a circuit of the light sources of a light projector. For example, in FIG. 9, alternating current from anAC power source 181 is rectified to direct current by arectifier 182 comprising a bridge circuit to magnetize anelectromagnet 183. Abranched circuit 184 branch from a main circuit is connected to alight projector 113.
Light projectors of the present invention are not limited to boring machines for metals but may be applied to any boring machines for wood or for use in offices. Moreover, the present invention is not limited to boring machines having a drill but may be applied to tappings or hand presses, etc., in which a setting position of material to be perforated is indicated instead of focussing at a position where an extension line of a drill intersects the surface of a material to be perforated. Therefore, a plurality of light projectors may be used.
