Product Description

Quick Locking Pins With Handle - 3D Welding Table Accessories

Quick Locking Pins With Handle product illustration

Quick Locking Pins With Handle are essential accessories for 3D welding tables, designed for efficient and secure workpiece positioning.

Key Components

L-shaped Handle: Features a red wavy handle made of anti-slip engineering plastic paired with a high-strength metal shaft, enabling one-handed operation without additional tools.
Locking Adjustment Nut: Black nut with anti-slip rolling pattern for fine-tuning locking stroke, compensating for platform hole tolerance, and ensuring gap-free locking.
Pin Body: Constructed from hardened stainless steel (hardness up to HRC40+), wear-resistant and rust-resistant, compatible with standard welding platform hole positions including D16/D28.
Steel Ball Locking Mechanism: Features 3-4 stainless steel balls embedded in the pin head, driven radially to expand and contract through internal conical screws for secure locking/unlocking.

Common Specifications

Specification	Platform Hole Diameter	Typical Locking Force
D16 Welding Table	16mm	Approximately 1500-2000N
D28 Welding Table	28mm	Approximately 2500-4000N

Working Principle

Unlocked State: Rotating the handle retracts the internal screw, causing steel balls to lose conical support and retract into the pin body, allowing easy insertion or removal from platform/fixture standard holes.
Locking State: Reverse handle rotation advances the internal screw forward, with the conical surface squeezing steel balls outward to press against the platform hole inner wall, generating up to thousands of newtons locking force for seamless rigid fixation.

Main Features & Advantages

Tool-Free Quick Operation: Simple handle rotation completes locking/unlocking, increasing loading/unloading efficiency by 5-10 times compared to traditional bolts and nuts, significantly reducing tooling changeover time.
Rigid Locking Without Clearance: Steel balls provide uniform multi-point stress distribution, eliminating shaking or clearance after locking to ensure positioning accuracy during welding/processing.
High Durability Design: Hardened stainless steel pin body with wear-resistant, corrosion-resistant steel balls withstands high-frequency loading/unloading and industrial-grade use environments.
Strong Adaptability: Mainstream specifications D16 (16mm holes) and D28 (28mm holes) compatible with most 3D flexible welding platforms and standard fixture hole systems.

Precautions

Must be used with standard holes of matching specifications on platform/attachments - avoid forcing into non-standard holes.
When locking, tighten handle until comfortable locking feel is achieved - avoid excessive force to prevent damage to steel balls and internal cone surface.
Clean welding slag and oil stains from locking pin surface after use, and regularly apply small amount of rust-proof oil to moving parts.
