Abstract
The utility model discloses a multipurpose ellipsograph with gears, and a drawing tool. The multipurpose ellipsograph with gears comprises a pair of gears whose speed ratio is 2; 1, a centering shaft, a rotating shaft, a sliding rail, a pen leg, etc. The multipurpose ellipsograph with gears is characterized in that the rotating shaft is sheathed with the centering shaft to make the large gear and the pinion gear directly engage, and the pinion gear is revolved around the large gear for one round, and autorotates for two rounds. The pinion gear is connected with an eccentric rod which drives the pen leg by a connecting rod to slide along the sliding rail. When people draw, the rotating shaft is rotated around the centering shaft for one round, and the pen leg can draw a complete and accurate ellipse figure. Ellipsographs with various standards and diverse purposes can be also made referring to the technical characteristics of the multipurpose ellipsograph with gears according to different needs of teaching, engineering baiting, etc.
Description
The utility model belongs to a kind of drawing instrument, is mainly used in the drafting ellipse figure, also is applicable on the engineering line or cutting elliptical shape to material, can also be used to working as compasses.
Existing a kind of planetary gear ellipsograph, consult Chinese Patent Gazette for Utility Models on February 11st, 1987, application number 86201492, this ellipsograph is made up of fixed wheel, paintbrush wheel, regulating wheel, cant beam, transmission rope etc., become planetary gear structure by the transmission rope transmission group, its structure is not compact, and keeping also has many inconveniences.
The purpose of this utility model is the defective that overcomes above-mentioned ellipsograph, and a kind of compact conformation is provided, and is easy to use, is convenient to the instrument of the drafting ellipse of keeping.
Details are as follows with reference to Fig. 1 for concrete structure of the present utility model:
It is the gear of 2:1 that a pair of speed ratio is arranged, and gear wheel (3) is fixed on the centration axis (1).Pinion (4) with turning cylinder (2) but the lower end radially by the axle ， And axial rotation that is connected, slide rail (7) also is connected on the position radially, turning cylinder (2) lower end, and becomes an angle of 90 degrees with pinion (4) axial line.Turning cylinder (2) is socketed on the centration axis (1), and gear wheel (3) and pinion are directly meshed.When turning cylinder (2) rotated around centration axis (1), pinion (4) is existing, and himself also rotated around gear wheel (3) revolution, and pinion (4) circles around gear wheel (3) public affairs, two weeks of rotation.There is a bolt that has radial hole in the axle center at pinion (4) back side, connects an eccentric rod (5) by the bolt that has radial hole, and eccentric rod (5) is apart from the eccentric throw in pinion (4) axle center, i.e. O
1To O
2Distance be adjustable, eccentric rod (5) with pinion (4) rotation rotation ， And with same angular speed rotation.Pin (8) is connected by bolt by the end of connecting rod (6) with eccentric rod (5).When eccentric rod (5) rotates with the rotation of pinion (4), eccentric rod (5) drivening rod (6), connecting rod (6) drives a pin (8) and slides along slide rail (7) linear reciprocation.The eccentric rod (5) that pinion (4) connects is in eccentric throw, i.e. O
1To O
2Distance determines afterwards that by the intended size adjustment eccentric rod (5) is by the bolt on pinion (4) axle center be locked (on pinion (4)).Eccentric rod (5) is connected with connecting rod (6), at the horizontal range of centration axis (1) axis with a pin (8) axis, i.e. O
1To O
3Between air line distance determine that by the intended size adjustment back link (6) is locked on eccentric rod (5) by the bolt of eccentric rod (5) end.Turning cylinder (2) with being connected of slide rail (7) can be weld, be threaded, form such as hinge connection, grafting.Centration axis (1) is rotated in order to prevent to draw, can be on centration axis (1) leftover bits and pieces appropriate location by the bolt angle (9) that is locked.
This ellipsograph can be made into the specification as common drawing instrument, can be placed on keeping in the drawing instrument box when not mapping.Also can be according to the different needs of drawing ellipse figure, be made into diversified in specifications, the ellipsograph that purposes is different.Be suitable for imparting knowledge to students the specification of usefulness as in teaching, using, this ellipsograph can being made into, a pin be made into can the clamping chalk form.If pincers worker line usefulness, a pin can be made into can the clamping scriber form.Also a pin of this ellipsograph can be made into the form of the various cutting tools of energy clamping, as the oval blanking tool of different work posts on the engineering.If the eccentric rod on this ellipsograph (5) and connecting rod (6) are removed, a pin (8) is locked with bolt just can does the compasses use in a certain position of slide rail (7).
Figure of description: be the gear Ellipsograph structure schematic diagrames of using more.
The step of using this ellipsograph drafting ellipse figure is: adjust the eccentric throw of eccentric rod (5) apart from pinion (4) axle center earlier, even O
1To O
2Distance be given ellipse long and short axle semidiameter 1/2nd, adjust the back and eccentric rod (5) be locked by the bolt on little tooth axle (4) axle center; Adjust the horizontal range between centration axis (1) axis and a pin (8) axial line again, even O
1To O
3Between air line distance be given long axis of ellipse radius, adjust the back and connecting rod (6) be locked by the bolt on eccentric rod (5) end.By oval direction position, tiptoe under the centration axis (1) is aimed at oval garden heart And by bolt angle is fixed simultaneously then.Rotate turning cylinder (2) and rotate a circle, both the drawn ellipse figure of an intended size of a pin along centration axis (1).
Claims (5)
1, a kind of gear ellipsograph of using more, by speed ratio is that a pair of gear, centration axis, turning cylinder, slide rail, a pin of 2: 1 formed, gear wheel is fixed on the centration axis, pinion, slide rail are connected with turning cylinder, it is characterized in that: turning cylinder and centration axis socket make big or small direct geared engagement, pinion the time himself also rotates around the gear wheel revolution, and pinion connects an eccentric rod in diametric(al), and a pin is by connecting rod and eccentric rod Lian Jie And and can slide along slide rail.
2, according to the said ellipsograph of claim 1, its feature also is the eccentric rod that pinion connects, and eccentric distance can be adjusted, and adjusts the back and is locked by bolt.
3, according to claim 1 or 2 said ellipsographs, its feature also is the connecting rod that eccentric rod one end connects, and the distance of connecting rod can be adjusted, and adjusts the back and is locked by bolt.
4, according to the said ellipsograph of claim 1, its feature is that also turning cylinder is connected with slide rail, welds, is threaded, forms such as hinge connection, grafting.
5, according to the said ellipsograph of claim 1, its feature also is angle of centration axis leftover bits and pieces usefulness bolting.
