Description
Technical field:
The utility model relates to a kind of stationery, especially a kind of involute divider calipers.
Background technology:
Involute is modal a kind of particular curve in engineering, but due to its how much particularity, often in engineering design process, utilizes common graphing method, is not easy to draw more accurately involute, brings the inconvenience in design to thus engineering staff and learner.
Utility model content:
The utility model object is to provide a kind of involute divider calipers in order to solve the deficiency of above-mentioned technology, its drawing method is: a disk is fixing in one plane, one to roll bar tangent with disk all the time, a paintbrush is installed rolling on bar, make to roll bar and roll on disk, the line segment under paintbrush picture is involute.
In order to address the above problem, the utility model solves the technical scheme that its technical problem adopts and is: a kind of involute divider calipers, is characterized in that: it is by disk, rolls bar, paintbrush, large ball, little ball, groove, circular hole and the gear teeth and form.The edge of described disk is provided with the gear teeth, and is provided with groove in disk border central authorities; The described bar that rolls is provided with the gear teeth, and gear teeth interlock on the gear teeth and disk, and be provided with groove rolling bar central authorities is respectively provided with circular hole rolling bar both sides; Described paintbrush is arranged on and rolls boom end; Described large ball and little ball link together by bent axle, and large ball and little ball can rotate by flexing axle, and large ball is arranged in the groove of disk, and little ball is arranged in the circular hole that rolls bar.
The beneficial effects of the utility model are: a disk is fixing in one plane, and one to roll bar tangent with disk all the time, a paintbrush are installed rolling on bar, make to roll bar and roll on disk, and the curve of paintbrush under drawing is involute.
Accompanying drawing explanation:
For the technical scheme that more clearly illustrates that the utility model is implemented, below in conjunction with accompanying drawing explanation and embodiment, the utility model is further illustrated.
Fig. 1 is the utility model overall appearance structural representation.
Fig. 2 is ball connection diagram.
Fig. 3 is the side view of disk.
Fig. 4 is the cutaway view that rolls bar.
Wherein, 1-disk, 2-roll bar, 3-paintbrush, the large ball of 4-, the little ball of 5-, 6-bent axle, 7-groove, the 8-gear teeth, 9-circular hole.
The specific embodiment:
In the first embodiment shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of involute divider calipers, is characterized in that: it is by disk, rolls bar, paintbrush, large ball, little ball, groove, circular hole and the gear teeth and form.The edge of described disk is provided with the gear teeth, and is provided with groove in disk border central authorities; The described bar that rolls is provided with the gear teeth, and gear teeth interlock on the gear teeth and disk, and be provided with groove rolling bar central authorities is respectively provided with circular hole rolling bar both sides; Described paintbrush is arranged on and rolls boom end; Described large ball and little ball link together by bent axle, and large ball and little ball can rotate by flexing axle, and large ball is arranged in the groove of disk, and little ball is arranged in the circular hole that rolls bar.
In the second embodiment shown in Fig. 1, a disk is fixing in one plane, one to roll the connection function of bar by large ball, little ball and bent axle tangent with disk all the time, a paintbrush is installed rolling on bar, when making to roll bar and rolling on disk, due to the interlock disk of the gear teeth and roll between bar and relative sliding can not occur, so the line segment of paintbrush under drawing is involute.
