Topics of Today
Fitting is the process of assembling various parts manufactured in the machine shop. The various types of tools used in the Fitting Workshop are as follows.
In the last class, we had discussed the Electrical Engineering Workshop in a detailed way, and in today's class, we are going to discuss Engineering Fitting Workshop.
The Tools used in Fitting workshop are as follows:
The detailed explanation of above mentioned Fitting Workshop Tools are as follows.
Holding tools are also known as Work Holding devices in the Fitting workshop. They are used to hold all types of components between jaws(Fixed Jaw and Movable Jaw).
The Various Work holding devices are
The Explanation for the Work Holding Devices is as follows.
The Parts of Bench Vice are:
The Jaws are used to hold the workpiece by rotating the handle. In that, one jaw is fixed and the other is movable.
All the parts like a handle, jaws etc.are connected to the body of a bench vice.
If the handle is rotated in CW direction, then the work-piece is fixed between two jaws.
If the handle is rotated in CCW direction, then the workpiece is loosened from the jaws.
This is the explanation of Work Holding Devices in the Fitting Workshop. 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.r.t. the specimens used in the workshop and that you will see in the engineering workshop.
They are 3 types of Marking tools used in the fitting workshop and are as follows.
The Explanation for the Marking tools is as follows.
Measuring Tools are used to measure any component w.r.t. the dimensions. Without these tools, it is not easy to measure the accurate values of the given .components.
Some of the Measuring Tools used in Fitting Workshop are as follows.
The detailed explanation of 10 Measuring Tools was HERE
Cutting Tools are used to cut the given specimen(plate) w.r.t.the given dimensions. The material of the given specimen in the Fitting workshop is Mild Steel.
The Cutting Tools used in Engineering Workshop are
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:
Hacksaw is classified into two types.
In the above, hacksaws were different w.r.t.the frames only and the rest of the parts were the same. 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 as 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 degree of coarseness.
The various types of Files are as follows.
The explanation of above types of Files in Engineering Workshop are as follows.
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 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.
It is in the form of a Needle which is used to remove the material from the Keyhole like cross-section components.
Now Let's discuss Methods of filing.
There are two methods of filing.
The explanation on Methods of filing is as follows.
Filing in a direction perpendicular to the axis of a component is called Cross Filing. This filing method is used mostly in the Fitting Workshop.
Filing in a direction parallel to the axis of a component is called as Draw Filing.
These tools are used to strike or hit the workpiece by the application of external force.
The Three Types of striking tools used in carpentry workshops are as follows.
The explanations are as follows:
These are the different Striking Tools used in Engineering Workshop.
These are the different types of Striking tools used in the Fitting Workshop. Let's see the operations, safe work practices, and Power Tools used in Engineering Workshop.
A sequence of operations used in the Fitting Workshop is as follows.
The tools which are driven by means of Power (Electric current) are called Power tools. In this article, I will be listing out 4 Power tools used in the Fitting workshop.
The detailed explanation of the above power tools is as follows.
The Power Hacksaw consists of the following parts.
When the power supply is given to the motor, the spindle attached to the motor rotates which is connected with the pulleys. The power is transmitted between the two pulleys by means of a belt.
One end of the link is connected with the pulley and the other end is connected to the fixed hacksaw frame which converts rotational motion into linear motion.
The position of the hacksaw on the workpiece is adjusted by means of a hand wheel.
The linear motion of the hacksaw cuts the workpiece by means of a fixed blade having teeth in a forward direction.
The forward stroke is the cutting stroke and the backward stroke is the idle stroke. In this way, the hacksaw can cuts the material which is fixed in the machine vice.
The circular saw is most commonly used for cutting wood, which may be used less optimally for cutting other materials with the exchange of specific blades.
Basically, all circular saws consist of a motor with a circular blade fitted on a spindle. It can be carried from one place to another place for performing the operations.
Drilling Machine is used to drill holes on the components. The Angle of the drill bit used for removing the material from the surface of the workpiece is 118 degrees.
Grinding Machine is used to remove the material having (low surface finish) from the surface of a workpiece by means of a Grinding wheel.
The Grinding wheel is a multi-point cutting tool which can have high MRR.
Here you can get the detail information of Surface Grinding Machine.
This is a detailed explanation of all the tools used in the Fitting Workshop. If you have any doubts, ask us and we will give a reply soon.
