嫁接机切割式供夹装置的设计与试验OA

Aiming at the problems of large size,low efficiency and poor stability of the grafting machine clamping device,a continuous cutting and clamping embryo type clamping device for the development of eggplant and fruit grafting machine was proposed.Based on the affixed grafting method of rootstock spike seedlings,a grafting clamp made of common PE ma-terial was taken as the research object,and a grafting machine cutting-type clamping device was designed,and the move-ment and structural parameters of the clamping head and the grafting clamp during the clamping process were analyzed,and it was determined that the slanting head could form an effective avoidance space compared with the planar head.The Box-Behnken response surface design method was used to establish an optimization model and carry out a clamping per-formance test on the device.The effects of cylinder pressure,single clamping response time and inclination angle of the clamp head on the qualified rate of clamping were analyzed.The results showed that the cutting clamping device has the best performance when the cylinder pressure was 0.688 MPa,the response time of single clamping was 1.445 s,and the inclination angle was 107.984°.The average qualified rate of clamping could reach 96.19%.Through the verification test,it was concluded that the qualified rate of the clamping device was 95.67%.At this time,the efficiency of the clam-ping device could reach 2 000 clips/h,which could meet the requirements of the grafting clamp supply and the clamping device was stable and reliable.Compared with the existing grafting equipment,the cost was significantly reduced,which could provide technical support for small-scale planting farmers to graft seedlings,and technical reference for the subse-quent research and development of grafting machine automation.
