WDS Component Parts has introduced a range of captive clamping pins for workholding applications. The range is suitable for use with large drill jigs, assembly jigs and machine guards, as well as any application where removable jig plates are used to speed up and simplify the machining and assembly processes.

The WDS range is available with four standard handles or without a handle

When jig plates are loaded onto a jig bed, they need to be quickly and securely clamped in position to enable accurate machining and assembly. Here, typically, a precision-ground retention bush will be fitted to the plate and held in place using a standard shoulder screw. A clamping pin will then pass through the positioning hole and screw into threaded holes on the machine bed to hold the jig in place.

This is a tried-and-tested method for loading and unloading large jigs quickly; however, there are flaws associated with traditional products. End users often find that the clamping pins are prone to becoming dislodged when the jig is moved, which can often result in the pin becoming lost and needing to be replaced. 

The WDS range features a ‘captive’ design claimed to ensure that the clamping pins are held in place at all times, even if the jig is subjected to vibrations or turned upside down. This is achieved thanks to the positioning of a small leaf spring located in the positioning bush and a notch at the tip of the clamp’s shaft. As the clamp is removed from the jig bed, the spring tightens around the notch and holds the clamping pin in place. This means that the clamp will not become accidentally dislodged.

Key features and benefits

  • The WDS range of clamping pins can be regularly moved from jig to jig without fear of failure year after year. According to the company, it is the first captive clamping pin that is fully self-retained.
  • WDS offers a choice of four handles as standard with its range: a traditional T-handle, a steel hand knob, a plastic handle or an adjustable torque knob, which ensures consistent clamping forces.
  • The choice is further complemented with the option to specify a fitted bespoke handle from the entire WDS range, as well as the option to order a clamping pin with handle fitted. All options are available ‘out of the box’, meaning the pins are delivered ready to go.
  • The captive clamping pins have been designed to offer maximum flexibility and reliability. To further this, the clamping collar is mobile on the pin when it is delivered. This allows the end user to modify the shaft length to fit the depth of the fixing plate –— once the ideal length is found, the collar can be welded in position or the shaft can be cross drilled and pinned.
  • The range is available in metric and imperial thread sizes, from M6 to M12 as ¼in to ½in UNC.
  • As with all of the standard parts in the WDS catalogue, 3D CAD models are available to download free from the company’s website. The parts are manufactured in house by WDS, meaning most orders can be satisfied from stock. Parts can be ordered online or through the sales office and are available for next day delivery or collection from the WDS trade counter.
