The present invention has the connecting rod of buffering vibration absorption ability, and its structural feature also is:
Described briquetting the briquetting liner is set in interior week, between described right sleeve and guide pillar, the sleeve liner is set.
Between described spring and axle sleeve, be provided with the left spring pad, between the right-hand member shaft shoulder of described spring and guide pillar, be provided with right compression spring.
Compared with the prior art, beneficial effect of the present invention is embodied in:
In the time of in applying the present invention to slidercrank mechanism or fourbar linkage, when ram speed need to gradually become zero, spring pressurized, thereby absorption portion kinetic energy buffering, when slide block was static, the spring force of generation compressed slide block, thereby makes Location accuracy more reliable; When slide block was started from scratch motion, spring was discharged gradually by pressured state, thereby has avoided the unstability in electric motor starting stage, makes slide block movement milder; The present invention is simple in structure, easy to loading and unloading, reliable in function.
