Description
Technical field
The utility model belongs to woodworking machinery component technology field, more particularly relates to the improvement of the optics indication device of bench saw sawing direction.
Background technology
Bench saw be a kind of can be along the woodworking machinery of straight line saw timber.Existing bench saw generally will regulate baffle plate earlier, or rule on workpiece in the saw first being processed.Add man-hour, timber is leaned against on the baffle plate, then with the sawing of manual propelling movement workpiece; Perhaps push sawing with manual location along line.During sawing, should note the location constantly, just can make the sawing direction correct all the time or remain with rule consistent, avoid saw kerf to depart from.But because of blocking of foreign material such as sawdust, the operative employee often is difficult for observing grasping, and therefore usually causes error too big, produces the substandard products waste product, causes waste.
Existing at present a kind of available laser beam indicates the device of sawing direction, and this device is installed on the saw blade and rotates with it, sends the rectilinear light beam of rotation.The rectilinear light beam of rotation projects on the workpiece, and the vision stop principle because of human eye forms the rectilinear picture on workpiece, be used for the location.But it will borrow brush to introduce the power supply power supply, and structure is therefore very complicated.
Summary of the invention
The purpose of this utility model, just be to overcome above-mentioned shortcoming and defect, provide a kind of with laser pen or be called planar light beam or the rectilinear light beam that " the planar light beam generator that with the light emitting diode is light source " patented technology produces in the name of first to file and indicate the sawing direction, thereby the shape and size error that can reduce to process, improve the processed finished products rate greatly, avoid waste; And having overcome the shortcoming of brush complex structure, rapid wear, power supply architecture is very simple, and is easy to adjust, and the optics indication device of various colors with the bench saw sawing direction of the different needs that satisfies different use occasions can be arranged.
In order to achieve the above object, a planar light beam generator is installed on the cutter retaining plate of bench saw.The planar light beam generator is connected with power supply with lead, and the planar light beam generator sends the planar light beam that central plane a branch of and the bench saw saw blade overlaps to the front lower place.This planar light beam projects into a thin straight line fully aware ofly on workpiece, this thin straight line promptly indicates the sawing direction of bench saw saw blade.
During installation, should make the central lines (position of regulating mounting screw is promptly fine-tuning) of the center line and the saw blade of planar light beam generator.During work, power on open the planar light beam generator after, the planar light beam generator just on workpiece projection go out a thin rectilinear light beam.During sawing, adjust workpiece at any time, observe before and after noting with hand, the projection of thin rectilinear light beam on workpiece remained correctly, and make saw blade all the time along the sawing of thin linear projection, or make thin linear projection remain with workpiece on rule consistently, just can process the saw kerf that meets the requirements.Thin rectilinear light beam is not only clear but also can not blocked by sawdust, and this has just significantly reduced the substandard products waste product, has avoided waste.
Power supply can be a kind of magneto-electric generator.The lead that it is fixed on two permanent magnets on the motor shaft of bench saw by symmetry, be fixed on the coil of two series connection on the frame of bench saw and connect two series coils and plane light-beam generator is constituted.The installation site of the coil of two series connection is corresponding with two permanent magnets.During bench saw work, two permanent magnets that motor rotating drives on the axle rotate synchronously, and its magnetic line of force is just by two series coil cuttings.According to electromagnetic induction, just can produce induced potential in two series coils, give the power supply of planar light beam generator.The advantage one of this power supply is the shortcoming that has overcome brush complex structure, rapid wear; The 2nd, complete automatic control switch, as long as motor and saw blade rotation just have planar light beam and produce automatically, in case motor and saw blade stall, planar light beam just disappears automatically; The 3rd, the power and energy saving needn't provide power supply separately.
The planar light beam generator be a kind of be the planar light beam generator of light source with the visible light emitting diode.
The planar light beam generator also can be a kind of be the planar light beam generator of light source with the laser diode.This planar light beam generator energy is more concentrated, so its light beam is clearer, eye-catching.
Light emitting diode can be that a kind of, wherein double-colored, the panchromatic light emitting diode of RGB and its control circuit in monochromatic, double-colored, the panchromatic light emitting diode of RGB constitutes the planar light beam generator jointly.For making thin linear projection clearer, can select the planar light beam color big, as white, blueness or redness etc. with the color contrast of workpiece.This in other words planar light beam generator can select the light emitting diode of corresponding color to send corresponding monochromatic light.As select dichromatic LED, then can make it send different monochromatic light as required by control circuit.As select the panchromatic light emitting diode of RGB, not only can make it send different R, G, B three primary colors monochromatic light as required by control circuit, but also can send the light beam of any color by R, G, the trichromatic control of B.Light emitting diode is non-stimulated to human eye, and is safer, and cost is also low.
The planar light beam generator can also be a kind of be that light source is the planar light beam generator of planar light beam through the set of lenses coupling transform with the light emitting diode, light emitting diode is installed in the parabolic mirror, the parabolic mirror rear portion has louvre.This structure makes the luminous energy of light emitting diode more concentrated, and efficient is higher, and light beam is also more clear.
Better effects if when the planar light beam generator is the adjustable angle formula regulates, uses more convenient.
The planar light beam generator can be made of the coaxial condenser and the cylindrical lens that are installed in laser diode or LED front area successively, also can be made of the coaxial condenser and the corrugated lens that are installed in laser diode or LED front area successively.Can also form by other optical texture.
Task of the present utility model comes to this and finishes.
The utility model is a light source with laser diode or light emitting diode, clearly indicates the sawing direction with planar light beam, can improve the processed finished products rate greatly, avoids waste; Various colors can be arranged to satisfy the different needs of different use occasions, indicate fully aware of eye-catching; And overcome the shortcoming of brush complex structure, rapid wear, simple in structure, easy to adjust.It can be widely used in the various bench saws.
