Types of Vices Used in Workshop and Clamp Devices

Hello friends, Today I am going to tell you about Vices which is mostly used in industries or workshop.


In these topic we will know about types of vices used in workshop and also we will learn about clamp devices.

Vices are used to hold the tool or a job in a workshop, when performing any operation like drilling, filing, taping, grinding, milling, etc.


These types of operation perform on a specific machine through cutting tool like drilling is done by drill bits, grinding is done by grinding wheel etc.


And for making cutting tool different types of cutting tool materials are used like carbon steel,high speed steel,etc. 

Because of its mechanical properties are of high strength and hardened.



So, let's get started to know types of vices used in workshop.

What is Vice?

Vice is a job holding tools, which is used to hold the job firmly in the workshop. 

The Vice is used to tightly hold the job while performing operations in workshops like filling, cutting, drilling, tapping, dyeing, etc.


Types of Vices

There are following types of vices used in workshop
  • Bench Vice
  • Pipe Vice
  • Tool Makers Vice
  •  Hand Vice
  •  Leg Vice
  •  Drill vice
  •  Pin Vice  
See in figure different types of vices which is used in workshop.

Bench Vice

This is a job holding devices that is often used to hold the tasks while performing operations such as sawing, filing, chipping, tapping, external threading, etc.
It is fitted above the bench.

There are two steel jaws on this vice which are hardened and having grooves on them. Its height is kept equal to the elbow of the artisan. Its body is made of cast iron or steel.

Its size is taken from the width of the jaw.
Its fixed jaw remains fixed and only the movable jaw moves and tightens the work when the spindle is tightened. 

To hold the finish works, regular jaws (jaws) should be coated with aluminum, brass or copper to prevent the finish surface of the work from deteriorating.

It is also called machine vice when it is fitted with a machine.

Bench Vice Parts and Functions

There are following parts are attached to the bench vice
  • Fixed Jaw
  • Movable Jaw
  • Jaw Plates
  • Spindle
  • Handle                
  • Box Nut  

See in figure parts of bench vice

Fixed Jaw

Fixed Jaw is always fixes in the bench with the help of a nut and bolt.

A fixed jaw is made with grey cast iron.

Movable Jaw

Movable Jaw moves back and forth according to the size of the job.

Movable Jaw is also made with grey cast iron.

Jaw plates

The jaw has a plates inside, which are fix by screw is known as Jaw plates.

These plates are fitted with cross-cuts, which create a grip on the job.

For making these plates carbon steel's metal are used.

Spindle

Movable Jaw has to consist of a spindle, which is made of mild steel.

Movable jaw moves back and forth only when this spindle rotates. 

Handle

Handle is fitted with the spindle and when rotate the handle clockwise and anticlockwise direction then spindle moves forward and backward.

The handle is made of mild steel.

Box Nut 

The nut that spindle passes through is called box nut as well as guide nut.

Box nut always fits in the fixed jaw.

It is made of cast iron or gun metal.

Points to be Noted While Fixing a Bench Vice

1. The height of the vice should be one meter from the shop floor to the top of the vice or equal to the artisan's elbow. 

2. It is advisable to fix the bench vice with bolts, nuts and washers above the top of the bench as it provides good shelter and strength. 

3. It should be in the level and parallel to the vice job workbench and shop floor. If it is not fixed to level then the material will rub more than one side on the job.

4. Its fixed job should be slightly out of the end of the workbench.  

5. The vice should be firmly fixed. If it is not held firmly, it will vibrate, affecting surface finish and precision.  

Pipe Vice

This type of vice is often used for round shape work and C clamping of pipes, especially plumbing and lock smith works. 

On it, 'V' shaped groove's jaw are cut, which allows the pipes and cylindrical bars to be well gripped while performing cutting, threading, etc.

See in above figure where clearly shows v shaped groove's jaw.

It is often fitted well at the end of the bench.

Tool Makers Vice

This type of vice is used to hold the difficult job which is in small size while filing and machining.

It can be swiveled to set the work in any angle. 

Hand Vice

This vice is used to grip screws, rivets, nails and other similar materials that are too small to hold in the bench vice. 

Sometimes it is also used to hold thin plates while drilling.


Leg Vice 

This type of vice is used to perform heavy and rough types of work such as bending, forging and chiseling and it can bear to a heavy work.

Drill vice

This is a strong vice with a movable joint. It can be moved forward and backward by rolling the handle of the movable jaw.

This vice is used while drilling on small pieces.

Pin Vice  

This vice is used to hold a small diameter of jobs such as pins, needles, etc.


Care and Maintenance of Vices

• The sliding back should not be used as an anvil. The vice should be tightened only by its handle. Hammer should not be used to obtain more leverage. 

• From time to time, the vice should be cleaned and applied to it and check its looseness. If the jaws become loose, they should be replaced.

 • When the vice is not in use, it should be kept loose.

Clamp Devices

Clamp devices are also used to holding the tool or a job.

There are following types of clamp devices found
  •  Vice Clamps
  • "C" Clamp
  • Tool Makers Clamp 

Vice Clamps

Using these jobs does not mark the marks of the vice jaws, and the finish of the work is not deteriorated.

Depending on the function, these joints are found in different sizes. They are made of soft material like copper, lead, aluminum, tin plate, etc. from the holding material.

"C" Clamp

It is a clamp to do all the work which is often used for all types of simple tasks. In its design there is a frame that is shaped like the English letter 'C'  and is a screw.

It is also used to hold jobs on an angle plate or drill machine table, and to hold two or more jobs together. A 'C' clamp of appropriate size should be used for a particular job. 

It should not be subjected to excessive pressure as this may cause the screw rod to turn. 

It is mostly used for marking, soldering, brazing, etc.

"C" Clamp

Tool Makers Clamp 

This clamp is also called parallel clamp and it is made of mild steel. It is used to hold small pieces together while assembling, marking, machining, drilling, riveting, screwing, etc.

These are 50 to 150 mm in different sizes and long jaws are found. On top of it, a clip is attached to the screw by screws to prevent it from falling apart while adjusting.

 

So I hope you all know the types of vices used in workshop as well as clamp devices very well.

 

Thank You.
