Why We Use Clamping And Locating Devices?

What are the principles of clamping?

Strength: The clamping system should be capable to hold the workpiece securely against the forces developed during operation.

Clamping device should be capable to be unaffected by the vibrations generated during an operation.

The clamping force should not dent or damage the workpiece with excessive pressure..

What are the basic principles of clamping mention at least three?

clamping force should act on heavy part(s) and against supporting and locating surfaces. clamping force should be away from the machining thrust forces. clamping method should be fool proof and safe. clamping must be reliable but also inexpensive.

What is six point location principle?

3-2-1 Principle of Location used in Jig & Fixtures: [1] It is also known as six pin or six point location principle. In this, the three adjacent locating surfaces of the blank (work piece) are resting against 3, 2 and 1 pins respectively, which prevent 9 degrees of freedom.

What is a bar clamp used for?

Bar clamps have adjustable arms that are easily widened or narrowed to fit the workpiece and, therefore, requires fewer turns of the screw spindle, compared to a C-clamp, to hold the piece tightly. Proper use of a bar clamp: Used for woodwork, especially for holding edges when gluing.

What is a fixture design?

“Fixture Design Basics” describes the components and purposes of fixtures and the fundamental concepts related to creating efficient fixtures. Fixtures are custom workholding devices used in many manufacturing operations to secure, support, and locate a workpiece.

What are locating devices or locators?

LOCATING METHODS AND DEVICES Locators are those parts of a jigs or fixture which helps a work piece to seat in proper position in it . Depend upon type of work, locators are designed .

What is the best method to locate a rough surface?

A reasonably flat surface can be located by three pins of equal height having spherical surfaces at the location points. 2. A rough, uneven or tapered plane surface should be located by adjustable location pins having spherical ends. 3.

What is the principle of location?

The 3-2-1 principle of location (six point location principle) is used to constrain the movement of workpiece along the three axes XX, YY, and ZZ. This is achieved by providing six locating points, 3 pins in base plate, 2 pins in vertical plane and 1 pin in a plane which is perpendicular to first two planes.

What is difference between jig and fixture?

Jigs are commonly used in drilling, boring, reaming and tapping, while fixtures are adopted for milling, slotting, shaping, turning and planning. Jigs are usually more expensive than fixtures. The construction of the jig is often designed more complex while the fixture designs are simpler.

What is meant by locating?

What is meant by locating and clamping a workpiece?

An additional machining force acting radially around the drill axis also forces the workpiece into the locators. The clamps that hold this workpiece are intended only to hold the workpiece against the locators and to maintain its position during the machining cycle.

Why diamond pin is used in fixture?

One Round Pin and one Diamond Pin are often used together to locate from two machined holes in a workpiece, or to align two pieces of a fixture, without binding. Diamond pins are relieved, to locate only in 1 axis.
