Abstract
PURPOSE: To enable to measure clamping torque continuously, by fitting the strain gauge to the sleeve to which the driving shaft, which has the end part fixed to the disc by which the epicyclic gear linked to the pinion gear of the driving source is supported, is inserted.
CONSTITUTION: Decelerated rotation force from the driving source is transferred to the driving shaft, which has the end part fixed to disc 34, through epicyclic gear 32, which gears with the inside teeth of internal gear 30 and is fixed pivoltally in the position of the regular triangle on disc 34 by shaft 36, by pinion gear 42 fixed to output shaft 40, and the clamping work of the bolt, the nut, and so on is performed through chuck 18 by driver bit 20. Since driving shaft 38 is inserted to sleeve 44 extending from the internal gear and strain gauge 52 is provided on sleeve 44, the counter load applied to bit 20 in the screwing work of screws is applied to sleeve 44 through internal gear 30 to distort it, and thus, clamping torque is measured.
