Abstract
The utility model relates to the technical field of measuring tools, especially to a measuring instrument used for measuring cutter cutting edge angles. The cutter cutting edge angle measuring instrument at least comprises a support for placing a cutter and driving the cutter to do angle deflection around a cutting edge; an optical screen arranged on one side of the support; a light beam generator with emitted light beam projected to the optical screen, the cutting edge of the cutter being located on rays formed by the light beam. The cutting edge angle can be obtained through a truncation relation between the light beam projected on the optical screen and the cutter cutting edge bevel edge and can be obtained through the angle deflection did by the cutter around the cutting edge; an angle sensor is cooperated with a display system for display; the measuring instrument of the utility model has relative high accuracy and precision, good visualization and high efficiency, can replace traditional manual measurement and meet mass industrialization production requirements.
Description
Technical field
The utility model relates to the survey instrument technical field, refers in particular to the measuring appliance that is used for edge of a knife angular measurement.
Background technology
Cutter, like kitchen knife etc., whether its cutting edge sharp, conformance with standard whether; Mainly be that this method accuracy and precision are all not high through range estimation or hand dipping at present, the human factor influence is bigger; The product fraction defective that dispatches from the factory is higher, is unfavorable for large batch of industrialization production.
For this reason, the applicant detects the problem that exists to conventional tool, and the spirit of adhering to the research innovation, keeping on improving is utilized its professional eye and professional knowledge, works out a kind of being convenient to and makes, and is fit to the edge of a knife angle measuring instrument that industry is utilized.
Summary of the invention
It is a kind of simple in structure, scientific and reasonable that the purpose of the utility model is to provide, and makes easily, easy to use, adopts photoelectric measurement, the edge of a knife angle measuring instrument that accuracy and precision are higher relatively.
The utility model purpose again provides a kind of suitable industry utilization, effectively promotes the edge of a knife angle measuring instrument of measuring operating efficiency.
For achieving the above object, the utility model adopts following technical scheme:
A kind of edge of a knife angle measuring instrument, it includes at least:
One supplies cutter to place also can drive cutter is done angular deflection around its cutting edge support;
One is arranged on the optical screen of support one side;
One light-beam generator, its light beam that sends projects on the optical screen, and the cutting edge of described cutter is positioned on the ray of light beam formation.
In the such scheme, support is connected with angular transducer, and angular transducer electrically connects display system.
Said light-beam generator is a laser instrument, and light-beam generator is installed on the adjustable articulator.
The utility model adopts photoelectric measurement, and the relation of when projecting on the optical screen through light beam and cutting edge roundness oblique angle limit truncation obtains the cutting edge roundness angle, and it can obtain through the angular deflection that cutter is done around its cutting edge; Cooperate display system to show by angular transducer; Accuracy and precision are higher relatively, and intuitive is good, replace traditional hand and detect; Efficient is high, meets the needs that industrialization in enormous quantities is produced.
The utility model advantage again is simple in structure, and is scientific and reasonable, makes easily, and cost of investment is low, and is easy for operation, and labour intensity is low, effectively promotes industrial upgrading.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model one of which preferred embodiment;
Accompanying drawing 2 is the utility model measuring principle synoptic diagram.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
Consult Fig. 1, shown in 2, be the preferable enforcement synoptic diagram for the utility model, the relevant a kind of edge of a knife angle measuring instrument of the utility model, this measuring instrument include one at least and supply cutter 6 placements and can drive cutter is done angular deflection around its cutting edge 61 support 1; One is arranged on the optical screen 2 of support 1 one sides; One light-beam generator 3, its light beam that sends projects on the optical screen 2, and the cutting edge 61 of described cutter is positioned on the ray of light beam formation.The vertical optical screen 2 of the light beam that light-beam generator 3 sends, cutting edge 61 horizontal of cutter are on the ray that light beam forms.Among Fig. 1, support 1 also is connected with angular transducer 4, and angular transducer 4 electrically connects display system 5; Realize that thus support 1 drives cutter when its cutting edge 61 is done angular deflection, show through display system 5 through the angle of angular transducer 4 with institute's deflection; Handled easily the person read, and intuitive is good.Support 1 lower end also is connected with a cross slide 7, moves cross slide 7 and can realize that cutter 6 laterally moves, and realizes measuring the edge of a knife angle of different azimuth.Said light-beam generator 3 is a laser instrument, and light-beam generator 3 is installed on the adjustable articulator, with the convenient location of regulating.
Shown in Figure 2 is the measuring principle synoptic diagram of the utility model; At first be with cutting edge 61 horizontal of cutter 6 on the ray that light beam forms; Be that cutting edge 61 is on the center line of light beam; At this moment the light that sends of light-beam generator 3 is stopped by the inclined-plane, both sides of the cutting edge 61 of cutter and can not just project optical screen 2, does not have the hot spot of orthogonal projection on the optical screen 2, and can produce the upper and lower sides flare that the inclined-plane, both sides of cutting edge 61 reflects to form.When support 1 drives cutter when its cutting edge 61 is done counterclockwise angular deflection; The upside flare can progressively be drawn close with superimposed to the center bright spot; Concordant until one of cutting edge 61 skew back face with the beam center line that light-beam generator 3 sends; Light beam is circular light spots of bright upper semi-circle at optical screen 2 formation centers then, and at this moment the angle [alpha] that turns over of support 1 is the angle of the center line of the relative cutter 6 of one of cutting edge 61 skew back face, can show through display system 5 through the angle of angular transducer 4 with institute's deflection.Equally, when measuring the oblique angle on opposite side inclined-plane of cutting edge 61, backward rotation support 1 in like manner can be measured the angle of center line that angle beta that support 1 turns over is the relative cutter 6 in opposite side inclined-plane of cutting edge 61.It is exactly edge of a knife angle that two angles are carried out addition, can accomplish this edge of a knife angular measurement.Move cross slide 7 and can measure the edge of a knife angle, both sides of other point of cutting edge.
The utility model is simple in structure, and is scientific and reasonable, makes easily, adopts photoelectric measurement to replace traditional hand and detects, and efficient is high, and accuracy and precision promote greatly, meet the needs that industrialization in enormous quantities is produced.
More than diagram is merely the utility model preferred embodiments, is not the usable range that limits the utility model with this, every on the utility model principle, making in the protection domain that equivalent change all should be included in the utility model.
