Ideal for fast cycle time operations, the new series of cam levers from KippÒ and ImaoÒ gives the user quick and secure loading and unloading of parts. The cam levers are designed to provide an ergonomic clamping function of part fixtures and optimum process productivity. Selections of 17 different handles are now available with different mounting options, sizes, profiles and clamping force ratings.
The levers are outfitted with either internal female threads or complete with male threaded studs for attaching to fixture bases, plates, tombstones, machine tables or other workholding elements. Once the preliminary assembly and tightening of the threaded elements is completed (like traditional clamping fasteners), the cam action handles allow for quick final clamping or unclamping without the use of tools. The cam lever is simply pushed downward with only minimal hand force, while still generating between 200 – 1,800 lbs. of clamping force, depending upon the size range of the lever. Forces are created with only 0.050 to 0.060 inches (1.2 to 1.5mm) of lever travel in the Kipp units, and 0.07 to 0.129 inches (1.8 to 3.3mm) of travel with the Imao handles.
To unfasten, the handle is pulled upward which in turn releases the clamping pressure, allowing the part to be quickly removed.
The cam levers are offered in inch (10-32, 5/16-18) and metric (M5, M6 & M8) internal threads, plus inch (10-32, 1/4-20, 5/16-18, & 3/8-16) and metric (M5, M6, M8 & M10) external threaded selections. The Imao levers have female threaded bushings only, with thread sizes from M4 to M8 for mounting to fixture bases.
Kipp cam lever handles are constructed from cast aluminum or stainless steel, while the Imao levers are fabricated from steel with black oxide finish; a setscrew and internal pad are included to help prevent the levers from backing off and loosening during operation.
