Types of tools used in mechanical workshop
Do not let any heavy objects fall on the surface plate. Marking Tool:Surface Plate,Marking Table After this, next marking tools in workshop to know scriber, prick punch, center punch with their images.
Scriber Scriber are the very most important marking out tools in mechanical workshop or fitting shop. It is long, with both ends hard and tempered. It is used to place small dots on layout lines, punch marks on the center of drill holes.
This is used to make the marks larger than the prick punch because the point of the drill sits easily in it and the drill can be easily done with precision. Some center punches are automatic with a striking mechanism in the handle. The downward pressure of the striking mechanism is released into the handle to form the mark. Marking Tools:Scriber,Prick Punch,Center Punch Now we will know marking tools in workshop step by step are a divider, trammel and hermaphrodite caliper which is used to mark circles or used for marking on a round job.
Divider This is a marking tool or marking out tools used to mark circles, segments and other geometrical textures. It is also used to transfer textures. It is made of tool steel, and its points are hardened and tempered.
It is classified according to the maximum number of points it can open. Uses Measuring distance between two points. Direct transfer of measurements from steel rule.
Marking circles and arcs on metal jobs. It is used to draw circles and circles with more radiuses that cannot be drawn by a divider.
Hermaphrodite Caliper The hermaphrodite caliper is often used to find the center of the end of a round work or work that is cast and not completely round. It is also known as Jenny Caliper. Uses It is used for marking the parallel lines of inner and outer edges. It is used to locate the center of round bars. Divider and Trammel 'V ' - Block V 'blocks are often made of hardened steel or cast iron, which are found in many sizes.
These are often used for drilling on lay outs or round work. Often a 'U ' shaped clamp comes with it tied tightly to the work. Single Level Single Groove 'V' Block It has only one ' V' groove and has single rectangular slots to position the holding clamps on either side.
Double Level Single Groove 'V' Block It consists of two ' V' grooves at the top and bottom and a rectangular one on either side to accommodate the holding clamps.
Matched Pair 'V' Block This type of 'V' block is found in pairs that have the same size and uniform precision. They are used to support long shafts. These are made of high-quality steel. Which are mostly used in the mechanical sector for fabrication work. The marking tool is used to mark on a workpiece to get accurate size and shape.
Before using marking tools on a workpiece, firstly we should plan on it and do a rough diagram. Then we can easily mark the workpiece. A surface gauge is a type of marking tool. It is used to draw a line in layout work by using a surface plate. It is used for marking larger jobs. The surface plates are made of grey cast iron. Its manufacture consists of a heavy base and a spindle. It is a straightforward fix.
Fixed type surface gauge is fitted by manipulating a scriber with a clamp nut. The scriber is the most important marking out tool in the mechanical workshop. It is made of hardened steel material. Its length is about mm to mm long. Its diameter is 3 to 5 mm. It has a conical point and knurled body.
Scriber both ends design like a needle. It is used like a pencil to scratch or scribe lines on the workpiece. Let's go to the marking tools used in the fitting workshop. Marking Tools are used to mark any dimensions on the surface of a workpiece. Marking Tools can vary w. They are 3 types of Marking tools used in the fitting workshop and are as follows.
Measuring Tools are used to measure any component w. Without these tools, it is not easy to measure the accurate values of the given. Some of the Measuring Tools used in the Fitting Workshop are as follows.
Cutting Tools are used to cut the given specimen plate w. The material of the given specimen in the Fitting workshop is Mild Steel. Hacksaw is used for cutting rods, bars, pipes, etc. It consists of a frame, which is made of mild steel. Depending upon the pitch of the teeth Distance between the two consecutive teeth , blades are classified as:. In the above, hacksaws were different w. In the figure shown, one hacksaw has a fixed frame and the other has a movable frame.
They are used to remove the material from the surface of the workpiece in order to get a high surface finish. The Finishing tools are also called Files. Files are multi-point cutting tools. They are used to remove the material by rubbing on the metals workpieces to get a good surface finish.
Files are available in a number of sizes, shapes, and degrees of coarseness. This file is used to remove the material from the rectangular cross-sections. This file is especially used to remove the material from the inside corners which are at right angles. As a flat file cannot able to work at those corners, thereby square file is used. This file can be used at inclined positions to make them linear. It is in the form of a circular cross-section which is used to remove the material from the circular components to get a good surface finish.
It is in the form of a semi-circle that is used to remove the material from the semi-circular cross-section components.
