Measuring Clamping Force

In torque control a specified torque is placed on the fastener typically with a torque wrench.

Measuring clamping force.

Pallet clamping adapters are per application based and are fitted according to the specifications of the customer s pallet system. This is can be dependent on a number of factors but is largely a function of the preload force the force exerted in compressing the bolt and the tension force the force exerted in pulling the bolt apart. Like weight we measure the clamping force of headphones objectively and subjectively. Since earbuds and in ear headphones aren t held in place by the tightness of a frame we only measure the clamping force of over ear and on ear headphones.

See torque force design equations webpage and torque chart page for recommended fastener torque and equation data. One of the original and most commonly used method of attaching parts together is by means of a threaded fastener however the threaded joint and its fastening is a complicated matter. If clamping force falls below this threshold an alarm signal is generated. The operator can set a threshold clamping force.

Using torque to measure clamp force an inconvenient truth the traditional method for tightening fasteners is to turn the bolt head or nut using a torque wrench. While the tool may be very accurate measuring torque only measures how difficult it is to turn the bolt. One simply slides the power switch to on adjusts the display to zero if necessary applies a clamping force and reads the display. Clamping force measuring gauges for pallets are intended to quickly measure the holding force of individual clamping heads.

Factories production lines manufacturing plants all use a wide assortment of fastener and assembly systems. The two most common methods of applying preload are torque control and turn control. How to measure bolt fastening and force clamp. The holding force of clamping elements is relevant for both safety and quality.

This fastener bolt torque calculator will estimate the unknown torque diameter axial force applied and coefficient of turning friction for the given conditions. Monitoring of clamping force during machine set up monitoring of clamping force during. Advantages of using the fms. The functionality of a breadboard prototype force measuring clamp was tested in a laboratory by use of the combination of certified weights a load washer a.

A bolt s clamping force called preload is generated as the bolt stretches during tightening.
