Spring Clamps

Product catalog summary

Overview

This document provides detailed technical specifications, ordering information, and usage guidelines for various types of spring clamps, hold-down clamps, clamping spindles, thrust clamps, and clamping bars available from Fixtureworks. It includes product dimensions, clamping forces, materials, and installation notes, along with references to CAD downloads and pricing available on the supplier's website.

1. Spring Clamps

Spring clamps are offered in multiple sizes and configurations (right-hand and left-hand versions). Key parameters include dimensions (length, height, width), thread sizes (M4, M5, M8), clamping force ranges (e.g., 150-210N for QLSWC18R-18), and weight. The clamps feature clockwise (CW) or counterclockwise (CCW) handle operation. The document provides minimum and maximum dimensional tolerances for critical features.

2. Vertical-Handle Hold-Down Snap Clamps (Mini)

These clamps are available in stainless steel and other finishes, with model numbers such as QLSNDM08 and QLSNDM12. Clamping forces vary by model, with forces larger than 10N or 30N depending on the variant. Detailed dimensions include thread sizes (M8, M12), handle lengths, and incomplete thread lengths. Usage notes emphasize proper handle positioning for optimal clamping.

3. Vertical-Handle Hold-Down Snap Clamps (Standard)

Models like QLSND28-02 and QLSND30-03 are described with dimensions, clamping forces (20N to 60N), and thread specifications. Extension arms (e.g., QLSND-EX20) are available to increase clamping force. Angular adaptors (QLSND-AN10) allow for installation at specific angles (30° to 60°), enhancing versatility.

4. Push-Pull Snap Clamps

Push-pull style snap clamps (models QLSNS28-05, QLSNS30-07) are detailed with clamping forces ranging from 50N to 140N. Dimensions and handle angle recommendations are provided to ensure correct installation and operation. Related products and accessories are referenced for extended functionality.

5. Clamping Spindles

Clamping spindles (UB series) come in mini, standard hold-down, and push-pull types with various thread sizes (M4, M5, M6) and lengths. Dimensions such as spindle diameter, thread pitch, and overall length are specified. Installation examples are included to guide proper assembly.

6. Thrust Clamps

Thrust clamps (QLRC series) provide clamping forces from 0.2kN to 1.4kN. Both left-hand and right-hand versions are available with clockwise and counterclockwise handle operation. Detailed dimensions include body size, thread specifications, and stroke lengths. The document also covers thrust clamps with vertical handle variants (QLRCF series) with similar force ratings and dimensional data.

7. Clamping Bars

Clamping bars (QLRCS series) are designed for precision clamping with aluminum anodized bodies and steel linkage knobs. Clamping forces range from 55N to 175N depending on the model. The bars feature fast stroke and clamping stroke specifications, with detailed dimensional data for mounting and operation. The handle includes a clicking feature to indicate completed clamping, and the handle is replaceable when attachments are installed.

8. Technical Notes and Usage Recommendations

Handles are designed to click upon full clamping to provide tactile feedback.
Proper handle positioning is critical for achieving recommended clamping forces.
Attachments for clamping bars allow for specialized applications such as conduction testing and press-fit fixtures.
Allowable load, deflection, rotation torque, and rotation accuracy parameters are provided to ensure reliable and precise clamping performance.

9. Ordering and CAD Resources

All products include references to pricing, ordering, and CAD downloads available at fixtureworks.com, facilitating easy integration into design and procurement workflows.
