1.1 LITERATURE REVIEW
of multi spindle drilling machine. In the case of mass production where variety of jobs is less and quantity to be produced is large, it is very essential to manufacture the job at a faster rate. This is not possible if we produce by using general purpose machines. The purpose is to minimize the production time for drilling multiple holes in a work piece of different Pitch Circle Diameters (PCD). This design employs adjustable transmission systems along with a gear arrangement. This paper deals with design and development of multispindle drilling head to maximize the improvement of cycle time of the component.
Prof. Chukwumuanya- investigated Design and developed multiple spindle drilling head for mass production of Peugeot 504 automobiles brake drum. For this design they developed multi-spindle drilling head for drilling six holes at a time, in which four holes of Ø14.5mm and two holes of Ø8.5mm. They analysis the various gear forces theoretically. It concludes that mash increases production rate as compare to individual drilling operation.
Key Words: drilling machine, pitch circle diameter, transmission.
Prof. M.B. Bankar- Studied Improvement in design and manufacturing of multiple spindle drilling attachment, in which they used planetary gear system for drilling operations. In this case study we briefly give information about design of drilling attachment for motor selection to its gear box. This study concludes that Multi spindle drilling attachment increase productivity reduces cycle of operation and performs drilling operation more accurately.
1. INTRODUCTION Multiple-spindle drilling machines are used for mass production processes, a huge time saver where many pieces of jobs having multiple holes are to be drilled. Multi-spindle head machines are used in mechanical industries in order to improve the productivity of machining processes. It is used to drill holes for different pitch circle diameters. The centre distance between the spindles can be adjusted in any position as per the requirement of the various jobs. For keeping the centre distance between the drill spindles variable, they are connected to the main spindle by an Adjustable Transmission System (ATS).
1.2 COMPONENTS USED The components used in this multi spindle drill head are 1. Gears 2. Adjustable transmission systems (ATS) 3. Bearings 4. Top plates 5. Bottom plates 6. Drill chuck 7. Drill tool 8. Shank 9. Key 10. Shaft
In today’s market the customer demands the product of right quality, right quantity, right cost, & at right time. Therefore it is necessary to improve productivity as well as quality. The only way to achieve this is by using multi spindle drilling head. Designing of SPM is decided upon the principles of minimization of cost, improved productivity and better safety etc.
