Abstract
The utility model discloses a marking-out calliper gauge for work which is a tool used in marking-out for workpiece. The marking-out calliper gauge for workpiece is composed of a main measuring rule and three quantity feet. The marking-out calliper gauge for workpiece is convenient for measuring the inner and the outer diameters of a workpiece. The marking-out calliper gauge for workpiece is particularly suitable for drawing concentric circle outside a circular hole. The marking-out calliper gauge for workpiece solves the defect of complicated operations that when a circle is drawn outside a circular hole in the past, firstly the circular hole is filled with a chock, secondly the center of the circular hole is found out by the method of geometry, and a circle is drawn lastly. The utility model has the advantages of high precision, simple structure, simple manufacture and convenient operation. The work efficiency and the working quality can be enhanced.
Description
The utility model relates to the machined field, a kind of instrument that uses during the metal work-pieces line.
When workpiece line or Mold Making, often run into such situation.Draw several concentric circles as needs outside certain circular hole, to this, present operating procedure is that chock is clogged circular hole in the middle of adopting, and finds out the center of circle of chock with method of geometry, and then draws round according to given radius of circle.This method is more loaded down with trivial details, and influences precision.
The utility model has proposed a kind of workpiece line calliper at this problem, and outside the circular hole workpiece, the problem of drawing several circles is easier than present conventional method, precision is high in the time of solving the workpiece line.
Technical characterictic of the present utility model is as follows:
Accompanying drawing 1 is a structural representation of the present utility model
Structural representation when accompanying drawing 2 is close to for fixedly foot-measuring a of the present utility model and movable foot-measuring b.
Among the figure: D is the master chi, and a is fixing foot-measuring, and b and c are movable foot-measuring, 1,2,3, be the adjusting set screw, 4,5,6, respectively be that scales are arranged in upper, middle and lower.
Now contrast accompanying drawing and further specify it.
The top that the utility model has comprised master chi D that fixing foot-measuring a is arranged and movable foot-measuring b and C, b, the movable foot-measuring of c has flat seam can be through on the transverse arm of master RD, and rank, an angle are respectively arranged at the bottom of a, b, three foot-measuring b of c, it is the plane at the bottom of the foot, and two right angle terraces equate respectively with the distance of bipod bottom to master chi D transverse arm, the lateral surface of two foots can be the little circular arc of diameter (little of processing) or a rib is only arranged, the medial surface spacing of two foots equates, and establishes two spacing sums For l(sees accompanying drawing 2) top of movable foot-measuring b and c respectively is rotary with screw 1 and 2, and the bottom of movable foot-measuring c is equipped with telescopic spur, and is rotary with adjustment screw 3 in the installation place. The transverse arm of master chi D is marked with three row's scales, the starting point position of upper row's scale fixedly foot-measuring a inboard on the extensions of master chi transverse arm, the starting point of lower row's scale is the r length distance of 0 of upper row's scale in advance, the l/2 length distance that initial 0 leading upper row's scale of middle row's scale is 0 or l/2 length distance after 0 of lower row's scale.
The utility model can be made the serial calliper of different size according to actual needs.
Embodiment:
As in order to the opposite side distance of measuring circular hole internal diameter or other polygonal hole from the time, the foot of foot-measuring a, b is stretched in the hole, move movable foot-measuring b, and make the right angle step card of bipod rest the limit, hole, find out the ultimate range of Circularhole diameter or polygon opposite side, screw screw, the internal diameter in the hole of then can following row's scale directly reading measuredly.If want the external diameter of measuring workpieces, the inboard of foot-measuring a, b can be stuck in outside the measured place of workpiece, then the workpiece external diameter can directly be read from last row's scale, more than two kinds measure all with the inner side edge of movable foot-measuring b scale reading shown in lead on the survey chi transverse arm.In the time will drawing the concentric circles of circular hole.Only needing row's scale reading in the inner side edge aligning of movable foot-measuring c is circle hole radius and concentric radius sum place, example: circle hole radius R1=20mm, and concentric circles half R2-40mm, row's scale 60mm place during then the c inner side edge moves to, the pin of adjusting activity foot-measuring c is long.Screw screw 2 and 3, the handgrip master surveys can the draw concentric circles of the radius that requires of chi then.What need simultaneously to propose is, only designs upper and lower two row's scales as the main chi of surveying, and when then drawing concentric circles, moves the supreme row's scale of the inner side edge R1+R2-L/2 of foot-measuring c, following row's scale R1+R2+L/2 reading place, be too make things convenient for correct.
As seen, the utility model is simple in structure, and it is easy, easy to operate to make, and has improved operating efficiency and work quality, is the workpiece line.Particularly outside circular hole, draw concentrically ringed novel, utility.
Claims (2)
1, a kind of workpiece line calliper is characterized in that:
A, the main chi D of survey and movable foot-measuring b, c that fixing foot-measuring a is arranged have been comprised;
The top of b, movable foot-measuring has flat seam can be through on the main transverse arm of surveying chi D, and the main body of foot-measuring a, b, three foot-measurings of c, side all with lead that to survey the chi transverse arm perpendicular.
C, fixing each rank, hip one right angle, bottom of foot-measuring a and movable foot-measuring b, it at the bottom of the foot plane, and two right angle terraces equate respectively with sole end face to the main transverse arm distance of surveying R, the lateral surface of two foots can be the very little arc of diameter, the inside and outside survey interplanar distance of two foots is from equating, and establishes two spacing sum l.
The top of d, movable foot-measuring b and c respectively is rotary with screw 1 and 2.
The bottom of c, movable foot-measuring c is equipped with telescopic spur, and is rotary with adjustment screw 3 in the installation place.
F, the main transverse arm of surveying are marked with scale, initial 0 position of last row's scale fixedly foot-measuring a inboard is surveyed on the extensions of chi transverse arm the master, initial 0 the leading row of going up who arranges scale down carves 0: 1 length distance, and initial 0 of middle row's scale is lighted 1/2 length distance of 0 of the preceding row's of going up scale.
2,, it is characterized in that fixedly the lateral surface at the two ends of foot-measuring a and movable foot-measuring b also can only be a shuttle according to the described workpiece line of claims 1 calliper.
