Summary of the invention
The present invention is directed to the technical problem existed in prior art, provide a kind of and manufacture, easy to maintenance, the spatial crank-rocker mechanism of the convenient adjustable pivot angle regulated.
The technical solution adopted for the present invention to solve the technical problems is a kind of spatial crank-rocker mechanism of adjustable pivot angle, described driving shaft is equipped with driving gear engage with driven gear, power is reached axis, described rear Chain conveyer is assembled on axis, by described chain transmission by power transmission to front Chain conveyer group, front Chain conveyer group and described crank pit are arranged on front axle, by regulating sprocket ratio, adjustable crank, adjustable connecting-rod and the adjustable length of projecting shaft that turns to are to control pivot angle size.
Further, described chain realizes multiple velocity ratio in different Chain conveyer group, and Chain conveyer group is designed to the shape of the pagoda of the large minispread of two groups of positive and negative installations, can change velocity ratio by the transmission exchanging one group of sprocket wheel.
Further, described adjustment crank block changes the radius of gyration of crank thus in the position at described crank pit adjustment place, and control the amplitude peak that rotatingshaft swings, described crank block utilizes nut compressing on crank pit.
Further, described crank block connects a joint shaft bearing, projecting shaft is turned to connect another joint shaft bearing, be left hand thread by an one end between two joint shaft bearings, the other end is that the described connecting rod of right-hand thread is connected, by carrying out the length of regulating connecting rod towards single direction swivel link, after regulating length of connecting rod, locked position can be carried out by described locking nut.
The whole mechanism of the present invention changes velocity ratio by regulating Chain conveyer in the position of bidirection chain transmission group, and by the position of adjusting slider at crank pit place, simultaneously by changing the total length of connecting rod towards single direction swivel link, reach the effect that trace regulates pivot angle.

Embodiment
By reference to the accompanying drawings inventing type is further described.The schematic diagram that these accompanying drawings are simplification only illustrates the basic structure of type of the present invention in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Fig. 1 to Fig. 2, a kind of spatial crank-rocker mechanism of adjustable pivot angle, driving gear 11 is installed on driving shaft 12, driving gear 11 engages with driven gear 10, driven gear 10 and rear Chain conveyer group 13 circumference are fixedly installed on axis, with chain 14 transmission between rear Chain conveyer group 13 and front Chain conveyer group 15, crank pit 8 and front Chain conveyer group 15 are installed on front axle 16, adjustable crank slide block 7 is installed in crank pit 8, adjustable crank slide block 7 is connected with right joint shaft bearing 6, right joint shaft bearing 6 is connected with left joint shaft bearing 2 by connecting rod 3, the other end of left joint shaft bearing 2 is connected with turning to projecting shaft 1, thus drive turns to projecting shaft 1 to move back and forth in the angle of oscillation determined.
Shown in, chain 14 realizes regulating velocity ratio by being enclosed within different Chain conveyer group, and the shape that Chain conveyer group is designed to two groups of pagodas of large minispread can obtain different drive ratios by a chain 14.
Changed the radius of gyration of crank thus in the position at described crank pit 8 place by adjustment crank block 7, control the amplitude peak that rotatingshaft swings, described crank block 7 utilizes nut 5 to be fixed on crank pit 8.
As Fig. 2, crank block connects a right joint shaft bearing 6, projecting shaft is turned to connect a left joint shaft bearing 2, be left hand thread by an one end between two joint shaft bearings, the other end is that the described connecting rod 3 of right-hand thread is connected, by carrying out the entire length of regulating connecting rod towards single direction swivel link 3, and can be locked by described locking nut 4.
When production line needs the pendulum angle adjusting swing mechanism according to different product, the position of chain 14 in chain wheel set can be changed by Production requirement, regulate the position at adjustable crank slide block 7 place in crank pit 8, length and the length turning to projecting shaft 1 of fine setting connecting rod 3 simultaneously.
