Abstract
The force measuring device consists of a probe (needle probe and hole probe), a push rod, a front sleeve, an adapter sleeve, a spring, an intermediate sleeve, an adjusting sleeve, a battery, a wiring plug, a buzzer, screws, contact springs, heat shrink tubing, a tail sleeve, and a set screw. The probe and push rod are connected by threads, the front sleeve and intermediate sleeve are connected by threads at both ends of the adapter sleeve, and the intermediate sleeve and tail sleeve are connected by threads. A spring is mounted on the push rod. The adjusting sleeve is connected to the intermediate sleeve by threads. The contact spring is mounted in the side groove of the outer circumference of the adjusting sleeve. The battery is fixed in the adjusting sleeve by the wiring plug. The positive wire of the buzzer is welded to the contact spring for conductivity, and the negative wire of the buzzer is tightened to the wiring plug by a screw for conductivity. This device controls the magnitude of the axial force applied to the positioning claw by limiting the spring stroke and has an audible alarm function. Using this device can solve the problems of difficulty in controlling the axial force applied along the longitudinal axis of the contact element during positioning claw holding force detection, and the easy over- or under-voltage issues.
