In addition; Column is mounted on the lift slide, and this lift slide is set on the double-screw bolt that is fixed on the base, on the double-screw bolt of lift slide bottom, is installed with one and sets off nut; Can change the height and position of lift slide through setting nut, to satisfy the need of measurements.For the facility of regulating, often the pitch of double-screw bolt is bigger, and need have certain clearance between lift slide and double-screw bolt, goes up and down to regulate in order to quick, for this reason, causes lift slide when measuring, and angle of arrival swing etc. influence measuring accuracy.How to overcome the deficiency of traditional lathe tool geometric angle experiments of measuring appearance, promptly become the object of the utility model research.
Summary of the invention:
The fundamental purpose of the utility model is a kind of three auxiliary planes that can simulate stationary reference frame of design, can set up spatial relation directly perceived between cutter angular dimension and the auxiliary plane, is convenient to the lathe tool geometric angle experiments of measuring appearance of learning and understanding; And the existing column of improvement goes up and down to regulate and the structure of location.
The utility model technical scheme is achieved in that a kind of lathe tool geometric angle experiments of measuring appearance; Comprise base, be fixed on column, index dial on the base; It is characterized in that through the rotating shaft location one turntable being arranged on the base; The turntable surface activity is embedded with upper slide, the convex lathe tool benchmark block that is provided with of slide plate, and turntable is provided with the lock-screw of a conflict slide plate; Susceptor surface is provided with horizontal circle, and the center of circle and the rotating shaft core of this horizontal circle are overlapping, and the circular arc edge of turntable front end is fixed with the horizontal scale pointer, and turntable is provided with the lock-screw of a conflict in rotating shaft; The column bottom is fixed with vertical fixed head, and this fixed head middle part has vertical channel, and unsettled above turntable; The cantilever at column top is provided with the circular hole that a confession lifting column passes; The lifting column top is fixed with upper knob, the bottom is fixed with one and cranks arm; One column is positioned on this cranks arm through a turning axle, is fixed with the vertical scale pointer of directed in orthogonal index dial on cranking arm; Be evenly distributed with the guide groove of four roads and parallel axes on the lifting column periphery; Circularhole diameter direction on the said cantilever is provided with the resilient key in a pair of sensing circular hole, and two resilient keys can insert respectively in the guide groove on lifting column surface, form the structure of location lifting column; The extended line of said lifting column axial line and the axial line of rotating shaft are overlapping.During measurement; Lifting column can make things convenient for as required to be regulated and rotation; Make that column can be in the conversion of vertical pairwise orthogonal face, and can with the fixed head of vertical direction and three auxiliary planes of turntable plane composition stationary reference frame, set up reference frame intuitively; And vertical scale coiling turning axle suitably rotates, and can measure each nose angle parameter.
The guide groove cross section of said lifting column is an isosceles triangle, and the middle part circumference of lifting column is provided with an annular groove, and the cross section of annular groove is an isosceles triangle.Isosceles guide groove ability accurate centering, the easy design rotation adjusting of annular groove.
Said resilient key comprises steel ball and spring, is installed in respectively in the cantilever tapped through hole radially, and tapped through hole mouth place is installed with an adjusting knob, and this adjusting knob inner end is conflicted at spring end.Can regulate steel ball through adjusting knob and conflict, satisfy the need of highly automated location, also can keep the consistance of lifting column angle in the dynamics of guide groove.
Said lathe tool benchmark block is for having magnetic texure, and perhaps this is as the structure of selecting of magnetic.Chalybeate lathe tool can be held in a single day near the benchmark block, forms location automatically, need not hand and lives to measure.
The utlity model has be skillfully constructed, simple in structure, reasonable in design, reference frame is directly perceived, measuring accuracy is high characteristics; By the rotation of column, can simulate three auxiliary planes of stationary reference frame, can on two angle positions, accomplish the measurement demand again; Moreover the existing pillar construction that supports column of improvement can reach the precise height location, and the constraint of the column quadrature anglec of rotation, and it is more simple accurate to operate.
