The specific embodiment
Below in conjunction with the accompanying drawing in example of the present invention, the technical scheme in example of the present invention is clearly and completely described, obviously, described example is only the present invention's part example, rather than whole examples.Example based in the present invention, those of ordinary skills, not making the every other example obtaining under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Fig. 1 ~ 4, a kind of ellipsograph, comprise base 13, base 13 is connected with column 14, column 14 is connected with matrix 15, on matrix 15, be connected with push rod 16, push rod 16 two ends are connected with alignment pin, the termination of alignment pin is arranged in the chute 8 of the first support bar 12 and the second support bar 7, one end of the second support bar 7 is hinged on matrix 15, one end is connected with the second intermediate mass 19, handwheel 6, between the second intermediate mass 19 and the second turning cylinder 5, by bolt, be connected, the second turning cylinder 5 is connected with the second adjusting rod 4, the second adjusting rod 4 is connected with the second transmission rod 3, first support bar 12 one end and matrix 15 are hinged and connected, the other end is connected with the first intermediate mass 20, screw bolt passes fixed cover 18, the first intermediate mass 20 and the first turning cylinder 11, the first turning cylinder 11 is connected with the first adjusting rod 10, the first adjusting rod 10 is connected with the first transmission rod 9, the first transmission rod 9, the second transmission rod 3 is hinged and connected part and is provided with paintbrush connector 21.
The first turning cylinder 11 and the first transmission rod 9 between the oval semi-minor axis that is equivalent to of axial line distance h.Preferably, described the first adjusting rod 10 comprises that two parts form, first is the screw rod 10-1 being connected with the first turning cylinder 11, second portion is the connector 10-2 being connected with the first transmission rod 9 screw threads, screw rod 10-1 is connected by pin with connector 10-2, like this, and can be by rotation the first adjusting rod 10, change the first turning cylinder 11 and the first transmission rod 9 between axial line distance, and then can change oval semi-minor axis length.
Use procedure of the present invention is as follows: paintbrush 1 is fixed on paintbrush connector 21, base 13 fixes, rotate handwheel 6, handwheel 6 drives the second turning cylinder 5 to rotate, the second turning cylinder 5 drives the second transmission rod 3 to rotate by the second adjusting rod 4, the second transmission rod 3 drives the first transmission rod 9 to rotate, the first transmission rod 9 drives the first turning cylinder 11 to rotate by the first adjusting rod 10 again, in the process of rotating, the second transmission rod 3 can slide along the hole on the second adjusting rod 4, the first transmission rod 9 can slide along the hole on the first turning cylinder 11, and then make paintbrush 1 elliptical path of passing by.According to actual needs, if need to draw incomplete ellipse, by rotation hand wheel 6, can realize.
In addition, hinged by straight pin between the first support bar 12, the second support bar 7 and matrix, push rod 16 can slide along matrix 15, by regulating straight pin and push rod 16, and then can change the angle between the first support bar 12, the second support bar 7, also just change the angle of the first adjusting rod and the second adjusting rod, and then adjusted oval major semiaxis.
As preferably, described matrix 15 is provided with column fixing hole 22, matrix 15 one end flutings, and cell body two ends are provided with fastening bolt holes 17.After arranging like this, can adjust the height of matrix 15, and then can adjust the height of paintbrush 1.In addition, between paintbrush 1 and paintbrush connector 21, by fastening bolt, be connected, unclamp fastening bolt, mechanism can rotate around column 14, thereby changes the drawing direction of paintbrush 1.
As a step is preferred again, between described the second turning cylinder 5 and the second adjusting rod 4, be to be threaded between the first turning cylinder 11 and the first adjusting rod 10.
Described paintbrush connector 21 is connected with eccentric adjusting bar 2, and eccentric adjusting bar 2, the second transmission rod 3 and the first transmission rod 9 are hinged and connected.The present invention does not need, to the downward pressure of ellipsograph, only to need rotation hand wheel just, because in drawing oval process, departing from adjusting rod can be automatically to 2 one power of eccentric adjusting bar, thereby makes eccentric adjusting bar 2 to downward active force of paintbrush.
Wherein, the pin joint of supposing eccentric adjusting bar 2, the second transmission rod 3 and the first transmission rod 9 is revolute pair A point, and the track that A is ordered is planar oval, wherein major semiaxis
Semi-minor axis b=h,
Now the equation of locus of revolute pair A is
The foregoing is only preferred embodiments of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
