Fixtureworks has expanded its Stablelock Clamp series with the introduction of the QLRCW series, a versatile clamp designed for both thrust and pull clamping applications. This innovative clamp combines simplicity with high functionality, offering manufacturers an easy-to-use solution for securing workpieces during machining processes.
The QLRCW clamp operates through a straightforward handle-turn mechanism that grips a bar or pin shaft securely. When the handle is turned, balls within the mechanism are pushed outward by a tapered surface, which in turn compresses the collet to hold the shaft tightly in place. The spring-loaded clamping system ensures that the clamping force remains constant, enhancing the reliability of the fixture throughout the machining process.
One of the key features of the QLRCW clamp is its ability to function both as a thrust clamp and a pull clamp, depending on the workholding requirements. When used as a thrust clamp, it requires an additional clamping bar (sold separately) to achieve the necessary gripping force. The handle is released to retract the clamping bar, allowing for easy removal of the workpiece once the operation is complete.
In addition, when paired with a clamping pin (not included), the QLRCW clamp can also be used as a pull-type clamp. In this configuration, turning the handle locks the base clamp onto the pin, providing another option for secure and precise workholding.
For ease of use and accuracy, the QLRCW series features an indication line on both the body and the base of the clamp. This visual aid clearly shows when the clamp is in the engaged or disengaged position, while a distinct “click” sound further confirms when the clamping process has been completed successfully. This attention to detail ensures users can quickly and confidently verify the clamp’s status, reducing the chances of errors during setup.
The QLRCW clamps are made from durable materials, with the body and collet constructed from electroless nickel-plated pre-hardened steel, while the cover and lever arm are made from electroless nickel-plated 1045 steel. The handle is crafted from black phenolic plastic, ensuring a robust design that is built to withstand rigorous industrial use.
The clamps come in two clamping directions: clockwise (QLRCW40R0) and counterclockwise (QLRCW40L), providing flexibility depending on the specific needs of the operation. With up to 112 pounds of clamping force and a 150-degree rotation travel, the QLRCW clamp offers strong performance in a compact form factor, measuring less than two inches in height when in the clamped position.
This new addition to Fixtureworks’ product lineup is designed to meet the demands of industries that require reliable, efficient, and space-saving clamping solutions, such as automotive, aerospace, and other precision machining sectors. The QLRCW series offers manufacturers an easy-to-operate yet powerful tool for securing components during machining, improving efficiency and ensuring consistent results.
