The utility model is characterized in that the vernier scale which is composed of a graduated scale and a vernier on the graduated scale is arc-shaped, the arc-shaped graduated scale and the arc-shaped vernier are respectively connected to the two scribing compass arms by one end, and the scribing compass is provided with an arc-shaped vernier. The utility model not only can directly offer the required scribing length when used for scribing, but also has the functions of measuring angles and equalizing circumferences. The multifunctional vernier scribing compass has the advantages of multifunction, simple structure, convenient operation and high accuracy of the scribing dimensions, and can increase work efficiency.
Description
The utility model relates to a kind of scoring tool.
It is 89216409.3 Vernier shifting gauge that China's utility model patent discloses a kind of application number, it is to be connected with main scale and vernier respectively on the two leg bars of planing, the while main scale also is 90 ° with two strokes of legs respectively with vernier and is connected, when using this Vernier shifting gauge line, can directly obtain required size from main scale, bring convenience to use, but this is plan and is not had other function.
The purpose of this utility model is to provide a kind of and gathers multi-function in integral whole and multi-functional Vernier shifting gauge easy to use, that accuracy is high.
The purpose of this utility model is achieved in that multi-functional Vernier shifting gauge comprises two plan arm, scriber, pilot pin, vernier scales, its special character is by rule and is positioned at the vernier scale that the vernier on the rule constitutes is arc, and an end of curved scale chi and arc vernier is connected to two and plans on the arm.
Described curved scale chi, place, the two edges of its chi face is respectively equipped with the graduation mark of length metering unit and the graduation mark and the corresponding scale numeral of corresponding scale numeral and angular measure unit along its length direction, is provided with the five equilibrium numeral with the corresponding Equal round of graduation mark of angular measure unit in the middle part of the chi face.
At the top of Vernier shifting gauge is the jack that two junctions of planing arm are provided with perforation.
The utility model also include can with the attached chi of the vernier that the arm of planing is connected, its vernier is provided with the jack of perforation.
Characteristics of the present utility model are: be provided with the arc vernier scale on planing, not only when line, can directly provide the length of required line, also has the function that takes measurement of an angle with circumference in equal parts, one rule to be used, what this was plan simultaneously is simple in structure, easy to use, the accuracy height of line size can be increased work efficiency.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is provided with the structural representation of the attached chi of vernier for the utility model.
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the plan end of arm A, B of two of multi-functional Vernier shifting gauge is connected as a single entity by bearing pin (1), the center position of bearing pin is provided with the perforation jack (2) that can insert centering pin, the other end is connected with scriber (3) and pilot pin (4) respectively, and is fixed in respectively on the arm of planing by lock-screw (5).By the arc vernier scale that rule (6) and vernier (7) constitute, an end of its curved scale chi is fixedly connected on the arm A that plans, and an end that is positioned at the arc vernier on the rule is fixedly connected on the arm B that plans.Vernier is provided with the lock-screw (8) that vernier can be locked on the rule.The outer edge of rule face is respectively equipped with the graduation mark (9) of angular measure unit and the graduation mark (11) and the corresponding scale numeral (12) of corresponding scale numeral (10) and length metering unit along its length, the middle part of chi face is provided with the five equilibrium numeral (13) with the corresponding Equal round of graduation mark of angular measure unit along its length, as with angle be that the five equilibrium numeral of the corresponding Equal rounds of graduation mark of 120 degree is 3.Following table has provided the corresponding relation between the isodisperse and the number of degrees.This table can be located at the back side of rule.Equal round number of degrees table

Utilize multi-functional Vernier shifting gauge to draw bowlder, can directly obtain required radius of a circle from rule, to draw radius is that the circle of 110mm is an example, draw back two plan arms and the graduation mark of 110mm on zero graduation line and the rule on the vernier outward flange is alignd, with lock-screw vernier and rule are fixed, the distance between two pins is 110mm.In like manner, the zero graduation line on the vernier inward flange is alignd with angle index line on the rule, can obtain required angle.Use adjusting convenient especially, the accuracy height.
During Equal round, be divided into example to draw 6, the five equilibrium numeral 6 at rule middle part is corresponding with 60 ° of angle index lines, drawing back two arms of planing makes the zero graduation line on the vernier inward flange align with 60 ° of angle index lines on the rule, and be fixed with lock-screw, centering pin is inserted in the jack (2) at Vernier shifting gauge top, Vernier shifting gauge lies in to be waited to draw on the plane, and needle point is placed on the center of circle of Equal round, arc length between crossing two intersection points of inner edge and the circumference of arm of planing this moment two is 1/6 five equilibrium of circumference, two intersection point on lines can be obtained a chord length of six Equal rounds.If radius of a circle surpasses the length of the arm of planing, the method for available extended line obtains Equal round.
When exceeding this line scope of planing, can realize in the following manner, see Fig. 2, the pilot pin on the arm B that plans is taken off, the projection (16) of the attached chi of vernier (14) end is inserted in the arm B that plans, and it is fastening with lock-screw, being provided with on the vernier of the attached chi of vernier and connecting jack (15), in scriber or pencil insertion hole, is the center of circle with the centering pin (17) in the top jack (2) of planing, with the scriber in the vernier jack is radius, just can mark the required orthodrome that exceeds the scope of planing.The attached chi of vernier can be made into plurality of specifications.
