Zero Point Positioning Pull Stud User Manual

1. Product Overview

The XINCHENG PRECISION Zero Point Positioning Pull Stud is a critical component designed for advanced zero-point clamping systems. This system functions as an automatic fixture, enabling rapid tooling changes and quick clamping of workpieces in various industrial applications. Utilizing patented flexible center positioning technology, it ensures exceptional repeated positioning accuracy of less than 0.005mm.

The design prevents center deviation even under thermal expansion during high-speed rotation, and its single pull nail design eliminates misinstallation risks. These pull studs are made primarily from high-quality stainless steel, ensuring long service life and robust performance.

3. Setup and Installation

The Zero Point Positioning Pull Studs are integral to a modular clamping system designed for efficient workpiece handling. These studs facilitate quick and precise setup, positioning, and adjustment of workpieces or pallets within machine tools.

3.1 System Integration

The pull studs are designed to integrate with various zero-point clamping devices, workpiece pallets, or directly with workpieces that have appropriate positioning pin interfaces. They are crucial for achieving reference accuracy in a short time.

3.2 Types of Positioning Pull Studs

Different types of pull studs serve specific functions within the zero-point positioning system:

Figure 4: Illustrates the typical arrangement of zero-point positioning pull studs, categorizing them into Type A (Positioning), Type B (Orienting), and Type C (Locking) for comprehensive workpiece clamping.

• Type A (Positioning): These pins are used for primary positioning, establishing the main reference point for the workpiece.
• Type B (Orienting): Orienting pins help align the workpiece rotationally, ensuring correct angular placement.
• Type C (Locking): Locking pins provide the necessary clamping force to secure the workpiece firmly in place.

Ensure that the correct type of pull stud is used for its intended function to achieve optimal clamping and positioning accuracy.

4. Operation

Operating the Zero Point Positioning Pull Studs involves integrating them into your existing zero-point clamping system. The primary benefit is the ability to achieve rapid and precise workpiece changes, significantly reducing setup times and increasing machine utilization.

4.1 Quick Clamping Process

1. Preparation: Ensure the zero-point clamping system is clean and free of debris. The pull studs should be securely attached to the workpiece or pallet.
2. Placement: Carefully lower the workpiece/pallet, guiding the pull studs into the corresponding receivers of the zero-point clamping system. The tapered design of the positioning pins helps prevent jamming during this process.
3. Engagement: The system will automatically engage and clamp the pull studs. The self-locking function ensures a secure hold.
4. Verification: Confirm that the workpiece is firmly clamped and correctly positioned. The system's inherent precision ensures consistent placement.

4.2 Applications

These pull studs are versatile and can be applied in various scenarios:

• Machine Tool Loading: Used in automatic machine tool loading systems to ensure processing stability and efficiency.
• Assembly Applications: Micro-pallets with the SCHUNK VERO-S interface (or compatible systems) can utilize these pins as a carrier system.
• Automotive Component Processing: Direct clamping of workpieces like automobile cylinder blocks and cylinder heads, or connection via pallets, allowing for five-sided processing in a single setup.

5. Maintenance

Proper maintenance of your Zero Point Positioning Pull Studs is essential to ensure their long-term performance and maintain their high precision. As they are made of stainless steel, they are inherently durable, but regular care is still recommended.

• Cleaning: Regularly clean the pull studs and their mating surfaces in the clamping system to remove chips, dust, and coolant residues. Use a soft cloth and a suitable cleaning agent that does not corrode stainless steel.
• Inspection: Periodically inspect the pull studs for any signs of wear, damage, or deformation. Pay close attention to the tapered sections and threads.
• Lubrication: While stainless steel is resistant to corrosion, a light application of a suitable precision lubricant on moving parts or threads (if applicable) can help maintain smooth operation and prevent galling. Consult your clamping system's manual for specific lubrication recommendations.
• Storage: When not in use, store the pull studs in a clean, dry environment to prevent contamination and potential damage.

Note: Avoid using abrasive materials or harsh chemicals that could scratch or damage the precision surfaces of the pull studs.
