Abstract
The utility model intends to solve the technical problem that a traditional mathematic round catching instrument is operated complicatedly and cannot catch a circle center rapidly. In order to solve the problem, the utility model provides a mathematic circle center catcher, which comprises two mutually perpendicular linear rods, wherein the linear rods are connected, a fixation positioning pillar is disposed at the joint of the linear rods, and a movable positioning pillar is respectively installed on the linear rods in a sliding manner; the movable positioning pillars are connected by a scale plate, one end of the scale plate is fixed on the movable positioning pillar and the other end of the scale plate is installed on the other movable positioning pillar in a sliding manner; and a hatching pen is disposed on the scale plate. With the utility model during circle center catching, no special requirements are proposed during operations, points on the circle can be selected at will as positions of the positioning pillars, and the operations are convenient and rapid.
Description
Technical field
The utility model relates to a kind of seizure instrument, is specifically related to a kind of mathematics center of circle and catches instrument.
Background technology
Circular object and figure extensively come across the places such as teaching, engineering installation, construction drawing, building.Particularly, in the object of circular two-dimensional figure line and circular cross section, find the also mark center of circle to become requisite job requirement.Traditional seizure center of circle methods differ, and majority is by repeatedly measuring the position in the mark center of circle that the way of relative maximum gauge is approximate.
The operating type in traditional seizure the approximate center of circle of marked circle can not meet the requirement of study, work, engineering construction, and error is larger.
Summary of the invention
The technical problems to be solved in the utility model is traditional circular instrumentation complexity that catches of mathematics, can not capture rapidly the center of circle, for addressing the above problem, provides a kind of mathematics center of circle to catch instrument.
The purpose of this utility model realizes in the following manner:
The mathematics center of circle catches an instrument, and it comprises two orthogonal line bars, and line bar links together, and in described line bar junction, stationary positioned post is set, and activity orientation post is slidably installed respectively on described line bar; Between described activity orientation post, by scale, link together, and one end of scale is fixed on activity orientation post, the other end of scale is slidably mounted on another activity orientation post; On described scale, bow pen is set.
On each line bar, be respectively arranged with chute, and two chutes are mutually vertical, are provided with corresponding slide block on chute, activity orientation post is arranged on slide block.
Described chute is dovetail groove, and slide block is the dovetail slide block corresponding with dovetail groove.
Described activity orientation post comprises the base being arranged on dovetail slide block, and activity orientation cylinder is installed on base; Dovetail slide block is comprised of two dovetails, and two dovetails are bolted together; Described base comprises the upper bed-plate that is stuck between two dovetails and for the lower bottom base of stationary positioned cylinder, upper bed-plate and lower bottom base link together by joint pin, are provided with for the through hole of scale is installed on lower bottom base.
Described upper bed-plate is circular seat, and two dovetails offer respectively the draw-in groove corresponding with circular seat on corresponding position.
Described scale is U-shaped scale.
Described bow pen forms by nib with for the pen stand of nib is installed, and U-shaped through hole is set on pen stand, and pen stand is set on scale.
Described nib is connected with pen stand one.
With respect to prior art, when the utility model catches the center of circle, operating process is without specific (special) requirements, and the point that can choose arbitrarily on circumference is chosen in the position of locating dowel, convenient, fast.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that activity orientation post is arranged on the structural representation on slide block.
Fig. 3 is the structural representation of scale.
The specific embodiment
As shown in Figure 1, a kind of mathematics center of circle catches instrument, it comprises two orthogonal line bars 1, and line bar 1 links together, in described line bar junction, stationary positioned post 2 is set, on line bar 1, be respectively arranged with chute 6, and two chutes is mutually vertical, on chute 6, be provided with corresponding slide block 7, activity orientation post 3 is installed on slide block 7.Chute is dovetail groove, and slide block is the dovetail slide block corresponding with dovetail groove.Between described activity orientation post, by scale 4, link together, and one end of scale 4 is fixed on activity orientation post 3, the other end of scale is slidably mounted on another activity orientation post 3; On described scale 4, bow pen 5 is set.As shown in Figure 2, activity orientation post 3 comprises the base 31 being arranged on dovetail slide block, and activity orientation cylinder 32 is installed on base 31; Dovetail slide block is comprised of two dovetails 71, and two dovetails 71 are bolted together; Described base comprises the upper bed-plate 311 that is stuck between two dovetails and for the lower bottom base 312 of stationary positioned cylinder, upper bed-plate 311 links together by joint pin 313 with lower bottom base 312, is provided with for the through hole 314 of scale 4 is installed on lower bottom base 312.Upper bed-plate is circular seat, and two dovetails offer respectively the draw-in groove corresponding with circular seat on corresponding position, and like this, activity orientation post and dovetail slide block can be realized and relatively rotating.As shown in Figure 3, scale is U-shaped scale.Bow pen 5 forms by nib 51 with for the pen stand 52 of nib is installed, and U-shaped through hole is set on pen stand, and pen stand is set on scale.Nib 51 is connected with pen stand 52 one.In order to make accurate positioning, rapid, activity orientation post and stationary positioned post all can be arranged to taper.
The utility model operation principle is as follows: the end points of stationary positioned post is positioned in the circumference any point that is captured round, and the other any point of the end points of activity orientation post being put to circumference, by regulating the position of dovetail slide block the end points adjustment of another activity orientation post to be placed on to any point of circumference; The bow pen that now slides, being captured, round inside draws article one straight line.Apply above-mentioned the same manner, draw any second straight line in the circle that is captured, the intersection point of two straight lines is the round center of circle that is captured.
The utility model only just can capture the center of circle of any circle through twice setting-out, saves time.
