Design Analysis of Drilling Head for Steering Linkage Parts for Automobile Industry 2020-28-0329

The continuous efforts are been put by production engineers and process planning engineers to reduce or maintain minimum manufacturing lead time. The existing radial drilling machine took 184s for grooving six-holes in the tie rod. The operator has produced the six grooves by repositioning the tie rod in the fixture. The total machining time required for completing one tie rod is 184s out of which 138s were machining time and the remaining 46s was material handling time. In the present work design and fabrication of multi-spindle drilling, the head is done for increasing the production capacity of the manufacturing unit. The other merits of this design are quality and quantity products by minimizing operator fatigue. The methodology followed to accomplish the above work included concept development Process and modeling. Design calculations and finite element analysis were carried out on the critical part such as gear and gear on the shaft for design validation. The unit was fabricated in house and it was installed in the existing radial machine. The new machining time is 40s out of which 30s is machining time and 10s was the machine handling time. This was achieved by the incorporation of the newly designed machine tool and the production rate was increased by 78%.
