Description
Technical field
The invention belongs to bionic mechanical technical field, be specifically related to a kind of trough of belt moving axis formula half rotation mechanism.
Background technology
Half rotation mechanism is that one can produce asymmetric rotation, for the mechanism of animal-motion bionics.For forming Wei Si---the biotic plate propoller ship of good fortune effect of imitative insect flying of Chinese patent CN200310106145.1, for the walking mechanism of Chinese patent CN200510040830.8 rotary walking wheel and Chinese patent CN200910263070 double straight rod leg walking wheel.In half rotation mechanism using in these projects, the asymmetric rotation of blade or rod member is that Planetary Gear Transmission or the chain transmission by being placed in pivoted arm inside realizes.Driving system part is more, complicated structure, thereby weight is larger, work efficiency is not high yet.The present invention makes improvement to this, change the scheme that more complicated pivoted arm inside arranges train transmission, the scheme that part is minimum, form the simplest trough of belt moving axis formula half rotation mechanism is proposed, thereby can greatly simplify the structure of half rotation mechanism using in aforementioned each patent, aforementioned each bionic mechanical is improved in force.
Summary of the invention
The object of the present invention is to provide a kind of trough of belt moving axis formula half rotation mechanism of designs simplification, to replace used half rotation mechanism that structure is more complicated, weight is larger in an existing class animal-motion bionics machinery.
Trough of belt moving axis formula provided by the present invention half rotation mechanism comprises main shaft 1, crank 2, trough of belt moving axis 3, half bull stick 4, trough of belt axle sleeve 5, longitudinal chute 6, positioning sliding block 7, fixed-hinged support 8, frame 9; Main shaft 1 is arranged in frame 9 with fixed-hinged support 8, one end of crank 2 is connected with main shaft 1, the other end of crank 2 is fixedly connected with trough of belt moving axis 3, trough of belt moving axis 3 is arranged in trough of belt axle sleeve 5, trough of belt moving axis 3 can relatively rotate with trough of belt axle sleeve 5, and trough of belt axle sleeve 5 is fixedly connected on the middle part of half bull stick 4, has the longitudinal chute 6 along rod axis direction on half bull stick 4, positioning sliding block 7 is arranged on fixed-hinged support 8 by cylindrical hinge, and positioning sliding block 7 can be in the longitudinally interior slip of chute 6.
Described equal in length to the distance of main shaft 1 and crank 2 of fixed-hinged support in frame 98 that be arranged on.
Chute on described trough of belt moving axis 3 is vertical with the axis of crank 2.
The length of the longitudinal chute 6 along rod axis direction on described half bull stick 4 must be greater than 4 times of length of crank 2.
The cylindrical side of the trough of belt axle sleeve 5 at the described middle part that is fixedly connected on half bull stick 4 is provided with longitudinal chute 6 and connects the breach being connected, and makes longitudinal chute 6 continue to pass through trough of belt axle sleeve 5.
The length of described positioning sliding block 7 equals the overall diameter of trough of belt axle sleeve 5.
In conjunction with Figure of description, trough of belt moving axis formula of the present invention half rotation mechanism is described: the main shaft 1 being arranged in frame 9 drives crank 2 to rotate, the trough of belt moving axis 3 that is connected in crank 2 ends is enclosed within trough of belt axle sleeve 5, drive half bull stick 4 to move, the motion of half bull stick 4 simultaneously is also subject to being placed in the constraint of the positioning sliding block 7 in longitudinal chute 6, thereby makes half bull stick 4 produce more complicated asymmetric rotation.In the time that trough of belt moving axis 3 turns to crank 2 position that trough of belt moving axis 3 overlaps with fixed-hinged support 8, the groove on trough of belt moving axis 3 overlaps with longitudinal chute 6, and positioning sliding block 7 can successfully slide along groove, thereby crank 2 is rotated continuously by positioning sliding block 7 smoothly.Simultaneously, because the length of positioning sliding block 7 is greater than the diameter of trough of belt moving axis 3, thereby the position positioning sliding block 7 overlapping with fixed-hinged support 8 at trough of belt moving axis 3 can be bonded into one with trough of belt moving axis 3 and trough of belt axle sleeve 5 simultaneously, prevent relatively rotating of trough of belt moving axis 3 and trough of belt axle sleeve 5, thereby avoided instantaneous half bull stick 4 overlapping with fixed-hinged support 8 at trough of belt moving axis 3 may be disturbed the uncertain rotation of generation.
Advantage of the present invention is as follows:
1, simple in structure, compared with the driving system of more complicated in existing half rotation mechanism, trough of belt moving axis formula of the present invention half rotation mechanism produces the same asymmetric rotation of half bull stick with minimum part, the simplest formation.
2, application trough of belt moving axis formula of the present invention half rotation mechanism can be simplified the structure of the various machineries based on half rotation mechanism greatly, alleviates their weight, improves their work efficiency.

Detailed description of the invention
Trough of belt moving axis formula provided by the present invention half rotation mechanism comprises main shaft 1, crank 2, trough of belt moving axis 3, half bull stick 4, trough of belt axle sleeve 5, longitudinal chute 6, positioning sliding block 7, fixed-hinged support 8, frame 9.As shown in Figure 1: main shaft 1 is arranged in frame 9 with fixed-hinged support 8, and one end of crank 2 is connected with main shaft 1, and the other end is fixedly connected with trough of belt moving axis 3, and the chute on trough of belt moving axis 3 is vertical with the axis of crank 2.Positioning sliding block 7 is arranged on fixed-hinged support 8 by cylindrical hinge, and fixed-hinged support 8 is equal in length to the distance of main shaft 1 and crank 2, and the length of positioning sliding block 7 equals the external diameter of trough of belt axle sleeve 5.Be fixedly connected with trough of belt axle sleeve 5 at the middle part of half bull stick 4, on half bull stick 4, there is the longitudinal chute 6 along rod axis direction, longitudinally the length of chute 6 must be greater than 4 times of length of crank 2, and longitudinally chute 6, through trough of belt axle sleeve 5, forms corresponding breach on the cylindrical side of trough of belt axle sleeve 5.Half bull stick 4 engages with trough of belt moving axis 3 by trough of belt axle sleeve 5 on the one hand, can rotate by strip winding groove moving axis 3; Engage with positioning sliding block 7 by longitudinal chute 6 on the other hand, can slide along positioning sliding block 7.
Engine drive main shaft 1 rotates, main shaft 1 drives crank 2 to rotate, the trough of belt moving axis 3 that is connected in crank 2 ends is enclosed within trough of belt axle sleeve 5, drive half bull stick 4 to move, the constraint that the motion of half bull stick 4 is also subject to being placed in the positioning sliding block 7 in longitudinal chute 6 simultaneously, thereby the more complicated asymmetric rotation that produces half bull stick 4.
In the time that trough of belt moving axis 3 turns to crank 2 position that trough of belt moving axis 3 overlaps with fixed-hinged support 8, the groove on trough of belt moving axis 3 overlaps with longitudinal chute 6, and positioning sliding block 7 can successfully slide along groove, thereby crank 2 is rotated continuously by positioning sliding block 7 smoothly.Simultaneously, because the length of positioning sliding block 7 is greater than the diameter of trough of belt moving axis 3, thereby the position positioning sliding block 7 overlapping with fixed-hinged support 8 at trough of belt moving axis 3 can be bonded into one with trough of belt moving axis 3 and trough of belt axle sleeve 5 simultaneously, prevent relatively rotating of trough of belt moving axis 3 and trough of belt axle sleeve 5, thereby avoid instantaneous half bull stick 4 overlapping with fixed-hinged support 8 at trough of belt moving axis 3 may be disturbed the uncertain rotation of generation, made half bull stick 4 keep the successfully motion continuously of former direction.
