Which of the following locating device is used to locate cylindrical jobs?

Explanation:

V-Blocks

• V-blocks are versatile and widely used locating devices specifically designed to hold cylindrical jobs securely during machining, inspection, or assembly processes. The V-shaped groove at the center of the block ensures proper positioning and stability of cylindrical objects, allowing for accurate operations. V-blocks are generally made from hardened steel or cast iron, ensuring durability and precision.
• The V-shaped groove in the block provides a natural cradle for cylindrical workpieces. When a cylindrical object is placed in the groove, it aligns itself automatically along the axis of the V. This alignment ensures that the workpiece is held firmly and does not move during machining or inspection. Clamps can be used in conjunction with V-blocks to further secure the job.

Advantages:

• High Accuracy: V-blocks provide precise alignment and positioning of cylindrical jobs, ensuring accurate machining or measurement.
• Versatility: They can be used for various applications, including grinding, milling, drilling, and inspection.
• Ease of Use: Simple design and straightforward operation make V-blocks easy to use, even for beginners.
• Durability: Typically made from hardened materials, V-blocks are resistant to wear and tear, ensuring long-term reliability.

Applications:

• Used in inspection processes to check roundness, concentricity, and other geometric dimensions of cylindrical jobs.
• Widely employed in machining operations such as drilling and grinding to hold cylindrical workpieces securely.
• Commonly used in assembly operations where precise alignment of cylindrical components is required.
