TuffCam Swing Clamps C-1. Frequently Asked Questions

1 TuffCam s Frequently Asked Questions C-1 When do you recommend the use of TuffCam s over the standard product? Applications where speed is essential, massive arms are required, or position sensing is necessary, use the TuffCam design most effectively. When speed is essential, standard s (which last millions of cycles in ordinary applications) may not live up to life cycle expectations. If a standard is damaged early in its life due to speed abuse, replacement with a TuffCam may be a way to maintain speed requirements and lengthen device life. Where arm mass damages the swing mechanism of standard s, the tri-cam design of TuffCam strengthens the ball and cam link. The beefier design, capacity, and reinforced rotation mechanism of the TuffCam could be your best solution. Can I run the TuffCam at any speed I want? No, there are restrictions. TuffCam s are capable of approximately two times the speed of standard s in prolonged use without damage. In the event that you need faster speeds or larger arms, please understand that the life of even TuffCam s is reduced. Consult the Time and Flow Rate chart on page C-2 to determine the maximum speed for your application. What makes the cam follower ball seat so special in these units? The three cams and cam balls guide the rotation of the plunger providing greater support and directional stability. The patented cam follower design is unique in the industry and uses solid carbide balls and composite ball seats. The ball seat design assures that the ball rolls in the cam rather than jamming and scraping resulting in wear on both the cam track and ball. The demands on my fixture have changed and I am considering your TuffCam s. Can I switch out TuffCam for your standard product? Yes, the TuffCam s have the same mounting envelope as their standard swing clamp counterparts. I want to use Work Supports with TuffCam s. Will the Work Supports cycle fast enough to keep up with the part change outs? There will be some lag between the unclamp of s and the full release of pressure in any work support circuit. This is critical with fluid advance supports. The circuit must have time to evacuate under low pressure to allow the plungers to retract for reloading the fixture. If speed is the issue in support retraction coordinating with TuffCam, an air advance support must be used with the air circuit released prior to hydraulic circuit release. When the hydraulic circuit is released, the support will begin to immediately retract pushing only the air from the line rather than the higher viscosity hydraulic fluid. I m using a high-volume pump and it is blowing out my s. Will TuffCam s take care of this problem? High-volume pumps often incorporate high-volume accumulators. An accumulator will yield excessive flow, approaching instantaneous infinite flow, and is intended for dynamic loads. Hydraulic clamps are used to hold static loads. Excessive flow may continue to damage clamps, even TuffCam clamps. We recommend changing to a pump designed for clamping applications restrict flow to the table on page C-2. My applications requires clamps to hit my part in the exact place every time. Should I use your TuffCam s? TuffCam s will be more precise in their point of contact. Keep in mind that any draft angle or side forces will ultimately damage the cam tracks of any and result in loss of precision. In the case of precision positioning, guide pins are recommended and may be implemented with a single-ended or double-ended arm. What defines a TuffCam? The single direction, tri-cam design of TuffCam produces the strength and reliability to support faster speeds and larger arms. This design also delivers noticeably better accuracy and repeatability over other brands. The clocking feature, included on all styles, dramatically reduces the time it takes to change arms for maintenance, replacement or design setup. How can I measure the clamp speed? The maximum speed of a is applicable to both clamp and unclamp function, as the momentum on the cam track and cam follower apply to both movements. To approximate the speed of your application: * Look down the centerline of the swing clamp, perpendicular to the arm. * Actuate your clamping system while watching the arm swing into position. * The eye can track speed of movement at roughly 1/16 second. If while looking directly into the end of the, you can observe the arm move through its swing, the positioning time should be somewhere around ½ second or longer. See flow rates and clamping time on page C-2. * If, while looking directly into the end of the, you cannot observe the arm move, or it is unclamped and the next thing you can see is the device is in the clamped position, the positioning time is something substantially less than 1/2 second. Your standard model clamp is at risk of premature failure. However, the TuffCam s can actuate at a faster speed. See flow rates and clamping time on page C-2. * It is possible to approximate the clamp time by adding the total active volume of devices in the specific control branch of your system, and dividing that volume (cubic inches) by your pump s output volume (cubic inches per minute) and then multiply that number by 60 (60 seconds per minute). This will give you the theoretical calculated time to move a device through its stroke, but does not account for flow loss due to restrictions in the system. *TuffCam is a trademark of Vektek LLC Vektek, February

2 TuffCam s TuffCam s were developed to meet your demand for high-speed, precise positioning and/or heavy arm applications.

Never allow swing arm to contact workpiece or fixture during arm rotation. * Cylinder capacities are listed at 5,000 psi maximum operating pressure, with a standard length VektorFlo arm installed. Minimum operating pressure is 750 psi for single acting, 500 psi for double acting. The clamping force is adjustable by varying the hydraulic system pressure. To determine the approximate output force for your application divide the cylinder capacity shown above by 5,000, and multiply the resultant number by your system operating pressure to obtain the approximate clamping force for your application. (Actual force will vary slightly due to internal cantilever loading, friction loss and/or return springs.) ** To allow for piece part height variations, it is recommended that the vertical travel be set to about 50% of the vertical stroke. *** To ensure maximum service life and trouble-free operation, restrict fluid flow per table on page C-18. **** In-port flow control requires the use of manifold mount ports.
