Chengdu Sanjiu Precision Granted Fastener Patent

[Abstract]:Chengdu Sanjiu Precision holds Patent CN223544646 U for machined-part fasteners. Constructed with fixed plates and threaded sleeves, coordinated components improve fastening stability for versatile machining applications.

According to the latest authorization announcement from CNIPA, Chengdu Sanjiu Precision Technology Co., Ltd. has obtained a utility model patent titled Fastener for Machining of Mechanical Parts, with Publication No. CN223544646 U. The patent application was filed in October 2024, delivering a more stable and adaptable fastening solution for component machining.

As core connecting components, fasteners directly determine assembly precision and equipment operational safety in mechanical processing. Conventional fasteners suffer from poor adaptability, inconvenient preload adjustment and recurring loosening under long-term service. Such drawbacks impair processing efficiency and trigger component damage or equipment breakdown under harsh operating conditions, restricting machining quality improvement.

Targeting existing technical defects, the patented design adopts modular construction consisting of fixed plate, auxiliary plate, bearing, threaded sleeve, movable screw rod, positioning frame, clamping plate and limiting frame to comprehensively enhance fastening performance via coordinated component operation.

The fixed and auxiliary plates form the base support structure. Mounted atop the fixed plate, the dual-plate layout boosts structural rigidity and eliminates deformation of single fixed plate under load for stable fastening foundation. Bearings fitted on the outer side of the fixed plate connect with the threaded sleeve to enable free sleeve rotation and precise tightening adjustment.

Threaded engagement between sleeve and movable screw constitutes the core regulating mechanism. Rotating the sleeve drives axial travel of the screw to fine-tune clamping force, avoiding part damage from over-tightening or loosening caused by insufficient preload. The adjustable structure fits workpieces of diverse materials and thicknesses and expands applicable scenarios significantly.

Combination of positioning frame and clamping plate improves fastening stability. Sliding grooves on the frame guide component movement, while the inner clamping plate closely contacts workpieces to enlarge bearing area and prevent localized crushing. Limiting frames nested in positioning grooves implement secondary locking to avoid positional shift and secure assembly accuracy.

With long-term expertise in mechanical processing, Sanjiu Precision’s patent validates its R&D strength in core components. Per the firm’s technical team, the patented fastener lifts component acceptance rate by over 10% and fastening efficiency by 20%, ideal for precision instruments and automotive parts requiring stringent assembly accuracy.

Industry-wide promotion of this technology upgrades machining fastening equipment, cuts production costs and strengthens manufacturers’ competitiveness. Going forward, Sanjiu Precision will develop serialized fasteners with diversified specifications and wide compatibility to fuel high-quality development of the machinery processing sector.
