Prototype of a Reciprocating Table Saw
DJ Sanghvi College of Engineering - Second Year Project
The reciprocating table saw is a prototype model for cutting wooden jobs to the desired dimensions using the Scotch Yoke Mechanism. This is applied by converting rotational motion produced by a series of gears (Gear Train) which produces linear motion of the attached hacksaw blade which cuts the job which is gradually elevated.
Scotch Yoke Mechanism
The Scotch Yoke (also known as the Slotted Link Mechanism) is a reciprocating mechanism, converting the linear motion of a slider into rotational motion, or vice versa. The reciprocating part is directly coupled to a sliding yoke with a slot that engages a pin on the rotating part.
Materials Used: 5mm Plywood, Hacksaw blade, Balsa Wood Block, Self Adhesive Material with low coefficient of friction, Quick Setting Adhesive, Epoxy.
Components Used: Base, Hacksaw Blade, Gear Train, Scotch Yoke Mechanism, Raising Lever.
Processes Used
Computer-Aided Design:
The design and plan for the Scotch Yoke Mechanism was made on the computers using Solidworks. Every part was first designed individually and then assembled. Once assembled, the mechanism is checked
Laser Cutting:
After designing the parts are cut from plywood by laser cutting,
Lamination of Laser Cut Pieces:
Sticking a number of smaller laser cut pieces to make a sturdier finished product.
Assembling, Testing & Optimization:
Once lamination is done, the parts are assembled together and then tested to see whether the mechanism is reciprocated. After which the design is optimized and final touches are made so that it can meticulously carry out the mechanism.
