Product Description

Product DescriptionLocking Pin

Locking pins are the core connection and fastening accessories specially designed for modular flexible welding systems, perfectly matching 2D, 3D and octagonal flexible welding tables with standard D16 and D28 hole grid systems. As the most fundamental assembly part of flexible welding tooling, locking pins play a decisive role in ensuring fixture stability, positioning accuracy and overall welding consistency, and are widely used in mechanical processing, sheet metal fabrication, steel structure welding and automated robot welding stations. Our locking pins are made of high-quality alloy steel materials and undergo strict quenching and tempering heat treatment. Through precision CNC machining and fine surface polishing, the pin body features high hardness, strong toughness, excellent wear resistance and anti-deformation performance. The internal high-precision steel ball locking structure ensures flexible expansion and contraction, stable elasticity and ultra-firm clamping effect. Even under long-term high-frequency vibration during welding work, the locking pin will not loose or disengage, maintaining lasting and reliable locking performance.Compared with traditional bolt fixing methods, the quick-release locking pin greatly optimizes the fixture assembly process. It realizes fast insertion, one-second locking and simple twisting release without auxiliary tools. The assembly gap is extremely small, achieving high-precision positioning effect. It can be widely used for platform splicing, fixing angle blocks, support blocks, clamping elements and various positioning accessories, helping workers quickly build, adjust and disassemble different sets of welding fixtures. The standardized production process guarantees high product uniformity and interchangeability. Each locking pin has smooth insertion and extraction, no jamming, no hole scratching, effectively protecting the precision of the welding table hole grid. After long-term repeated disassembly and assembly, the product still maintains stable dimensional accuracy and locking tightness, greatly reducing later maintenance cost and accessory replacement frequency.

Adopting modular design concept, the locking pins have strong compatibility and can freely match all standard flexible welding platform accessories. The effectively improves production flexibility, realizes rapid switching of different workpieces and multi-batch flexible production, greatly shortens fixture setup time, improves welding efficiency and ensures stable product quality.

With reliable quality, simple operation and strong practicability, our locking pins have become essential standard accessories for modern intelligent welding workshops, providing stable and high-precision fastening solutions for industrial welding and detection work.Specification

Packing & Delivery

FAQQ1.Can the head of the locking pin be replaced separately?Yes. This locking pin features replaceable-head structure. If the head is worn or damaged by impact, only replace the head accessory instead of scrapping the whole pin body, which effectively reduces spare-part procurement cost.Q2.Which hole-series of welding tables do locking pins fit?Available in D16 and D28 specifications for 2D & 3D flexible welding tables. Please select locking pins matching the hole size of your table.Q3.Will there be clearance or shaking after locking?Tight manufacturing tolerance ensures high-precision fit with table locating holes. Minimal clearance after locking guarantees firm connection and prevents jig accessories from shifting or shaking.Q4.Do I need special tools to replace the pin head?No special tools are required. The head can be quickly replaced onsite with easy disassembly and assembly.
