TO MAKE A 'T' - JOINT -04


AIM :

 TO MAKE A 'T' - JOINT

TOOLS REQUIRED

1. STEEL RULE & SCRIBER
2. TRY SQUARE & DOT PUNCH
3. 8" BASTARD FLAT FILE
4. 6" SMOOTH FLAT FILE
5. 6" SMOOTH TRIANGULAR FILE
6. SAFE EDGE FILE
7. HACK SAW BLADE & FRAME
8. BALL PEEN HAMMER

MATERIALS REQUIRED

1. 62 x 50 x 5 mm M. S. FLAT (2Nos.)
2. MARKING BLUE
3. COTTON WASTE

PROCEDURE

1. CUT OFF THE WORK PIECES FROM THE GIVEN RAW MATERIAL BY USING A HACK SAW BLADE AND FRAME. ALSO MARK THE RAW MATERIAL AS THE DIMENSION OF 62mm. LENGTH.

2. THEN FILE ANY TWO MUTUAL SIDES PERPENDICULAR TO EACH OTHER BY USING A 12" BASTARD FLAT FILE.

3. THE PERPENDICULARITY IS CHECKED BY USING A TRY SQUARE.

4. AFTER FILING THE DATUM SIDES MARK THE WORK PIECES AS PER THE GIVEN DRAWING BY USING A VERNIER HEIGHT GAUGE. ALSO APPLY THE MARKING BLUE IN TO THE SURFACE OF WORK PIECE FOR BETTER CLARITY.

5. THEN PUNCH THE MARKED LINES WITH THE HELP OF A PRICK PUNCH AND BALL PEEN HAMMER.

6. THEN REMOVE THE UNWANTED AREA OF WORK PIECE BY HACK SAWING. ( BOTH MALE AND FEMALE WORK PIECES)

7. AFTER THAT FILE THE BOTH WORK PIECES TO THE ACTUAL DIMENSION AS THE GIVEN DRAWING BY USING 6" SMOOTH FLAT FILE.

8. THE CORNERS AND EDGES OF BOTH WORK PIECES ARE FILED BY USING A 6" SMOOTH TRIANGULAR AND SAFE EDGE FILES.

9. AFTER COMPLETION OF WORK PIECES, THEN CHAMFER AND DE BURR ALL EDGES.

10. THEN ASSEMBLE MALE AND FEMALE WORK PIECES AND SUBMITTED FOR INSPECTION.

RESULT

MAKING OF A 'T' - JOINT DONE SUCCESSFULLY AS PER THE GIVEN DRAWING.

CENTRIFUGAL CLUTCH

MAIN PARTS 1. Fly wheel 2. Clutch plate 3. Clutch shaft 4. Pressure plate 5. Clutch spring 6. Bell crank lever 7. Centrifugal weight 8. Crank shaft CONSTRUCTION In this type of clutch, centrifugal force is used to keep the clutch in the engaged position. It is operated automatically depending upon the engine speed. It has a fly wheel, clutch shaft, clutch plate, pressure plate, bell crank lever and a centrifugal weight. The bell crank lever is fitted in to the pressure plate with the help of a lever is called bell crank lever. WORKING A simple diagram of a centrifugal clutch is shown in the above figure. When the engine speed increases, the centrifugal weight (A) fly off due to the centrifugal force. At the same time bell crank lever (B) presses the pressure plate(C) and the clutch plate (D) on the flywheel against the springs(G). This makes the clutch engaged. The torsion of spring (G) is designed for disengage the clutch below 500 r.p.m. So the power can't be transmit...

FOUR STROKE SPARK IGNITION (PETROL) ENGINE

FOUR STROKE PETROL ENGINE MAIN PARTS 1. PISTON 2. CYLINDER 3. CONNECTING ROD 4. INLET VALVE 5. EXHAUST VALVE 6. SPARK PLUG 7. CRANK SHAFT 8. FLY WHEEL 9. CAM SHAFT CONSTRUCTION A four stroke petrol engine have a piston, connecting rod, crank shaft, inlet valve, exhaust valve and a spark plug. The connecting rod is used to connect the piston and crank shaft. The spark plug and valves are mounted in the cylinder head. Also the valves are operated by cam shaft which is connected to the crank. In this type of engines, there would be a power stroke for every two rotations of crank shaft. It is also known as otto cycle. Each full rotation of crank having two strokes. So one stroke is  180° rotation of flywheel. A four stroke petrol engine having the following strokes. WORKING Induction stroke : The crankshaft moves the piston downwards (TDC to BDC). The inlet valve is open and a mixture of fuel and air is sucked into the combustion chamber. It is also known suction stroke. In this strok...
