  • Features: Vertical thrust clamps (QLRCF) provide precise clamping strokes with multiple mounting hole options for flexibility.

6. Clamping Bars (QLRCS Series)

  • Available in various lengths (100mm to 200mm) and diameters (8mm and 12mm).
  • Materials: S45C steel with chrome plating and ABS resin knobs.
  • Features: Can be cut to desired length; compatible with QLRC and QLRCF thrust clamps.

7. Precision Thrust Clamps (QLPCT Series)

  • Models: QLPCT20-07 and QLPCT20-13
  • Clamping force ranges from 55N to 175N (initial to final).
  • Materials: AC7A aluminum anodized bodies, S45C steel clamping bars with solid film lubrication, phenolic plastic knobs.
  • Features: Provide precise and consistent clamping position with spring-loaded constant force; handle clicks to indicate completed clamping.
  • Technical Specifications: Allowable attachment weight on clamping bar is 500g with ±0.05mm deflection; allowable rotation torque is 0.5N·m; rotation accuracy ±0.1° without load and ±1° under load.
  • Usage: Ideal for recessed part clamping, press-fit fixtures, and conduction test fixtures requiring precise projection.

8. Accessories and Installation Notes

  • Extension Arms (QLSND-EX20): Used to extend clamping reach; supplied with hex socket head setscrews.
  • Angle Adaptors (QLSND-AN10): Allow handle installation where rotation is restricted; installation requires handle removal and wrench use.
  • Clamping Bars (QLRCS): Can be shortened; compatible with thrust clamps; detailed dimensions and thread specifications provided.
  • Installation and Usage Tips: Handles are replaceable; torque should not be applied to linkage ends during handle installation/removal; clamping bars should be locked when installing attachments to prevent torque damage.
