HFY Series Y-Type Pivot Swing Pneumatic Gripper

Brand: SOLH by Richge Technology 

Product Overview

     SOLH HFY series is compact Y-shaped swing gripper driven by single piston and pivot lever mechanism, direct alternative to SMC MHC2. Core characteristics: lever torque amplification for strong clamping force, large swing opening angle, slim body for tight installation space. Ideal for round, curved and irregular small components, widely used in electronics, hardware, plastic part and light-duty assembly stations.

Core Structure & Working Principle

   1. Transmission: Single piston pushes pivot lever assembly to convert linear motion into Y-type swing movement. Lever structure amplifies output torque for powerful clamping.

   2. Operation Modes

     -- HFY: Double acting (standard) – bidirectional air control for open & close

     -- HFTY: Single acting Normally Open – air supply clamps; spring automatically opens after pressure loss

   3. Swing Angle: Max open +30°, overclose -10°, total effective swing approx. 40°, provides sufficient opening clearance for picking parts.

   4. Construction: Hard anodized aluminum body, high-strength jaws, built-in magnetic ring. Three mounting surfaces (bottom / side / rear). Integrated adjustable throttle valves for independent speed control.

   5. Position Accuracy: Repeat positioning accuracy ±0.02mm, stable for light-duty precision picking.

⚠️ Important Note: Clamping torque declines as jaw extension length increases. Safety factor ≥1.5 must be reserved during load calculation.

Preferred Application Scenarios

   ✅ Prioritize HFY if:

     -- Workpieces are round, arc-shaped or irregular miniature components (electronic terminals, small plastic housings)

     -- Require relatively large opening angle (~40°) within limited installation envelope

     -- Height/width restricted equipment layout; Y swing structure saves more space than parallel grippers

     -- Light load ≤5kg, high-frequency cycling, demand cost-effective actuator

     -- Need flexible three-surface mounting for compact custom tooling

Selection Comparison: HFY VS SMC MHC2

Key Selection Guidelines

   1. Bore selection based on workpiece mass & jaw extension

     -- Light load ≤1kg → ø6/10; Medium load 1~5kg → ø16~32

   2. Operation mode selection

     -- General continuous production → HFY double acting

     -- Need automatic opening after power cut → HFTY single acting NO

   3. Mounting layout

     -- Default bottom mounting preferred; side mount for narrow width; rear mount for assembly line transfer stations

   4. Speed adjustment

     -- Utilize built-in adjustable throttle valves to control swing speed and avoid workpiece impact

   5. Position feedback

     -- Install CMSH / DS1-G magnetic switches on dual grooves to detect fully open & closed state
