Number in the figure: 1 measuring cylinder, 2 measure axle, 2a measuring pressure plate, 2b guide head, 3 axle springs, 4 spacers, 4a axial pass trough, 5 measure finger, and 5a measures gib head, 6 steel balls, 7 radial springs, 8 workpiece, 9 cavities, 10 position transducers, 10a transducer probe assembly, 11 oil-containing linings, 12 calibration elements.

Embodiment

Referring to Fig. 1, Fig. 2, the version of the present embodiment Intermediate gasket thickness manual measurement frock is:

Measure axle 2 and be sleeved in measuring cylinder 1, and can in measuring cylinder 1, move axially, between measurement axle 2 and measuring cylinder 1, be provided with oil-containing lining 11; Position transducer 10 is fixedly installed on the top of measuring cylinder 1, and transducer probe assembly 10a is butted on and measures the top end face of axle 2, be the top end face of measuring axle 2 be measurement face; The bottom of measuring cylinder 1 is set to cavity 9, connects firmly at the measuring pressure plate 2a of the bottom of measuring axle and is arranged in cavity, with the bottom surface of measuring pressure plate, presses the upper surface at workpiece 8, for the ease of location, in the bottom surface of measuring pressure plate 2a, is provided with guide head 2b.

In cavity 9, between the end face of measuring pressure plate and measuring cylinder, be provided with axle spring 3, be on the circumferential position staggered with axle spring 3, be disposed radially spring latch lock, between the radial spring of spring latch lock and steel ball, series connection arranges and measures finger, measure finger and radially forming interlock with steel ball, measurement finger 5 extends and protrudes from the bottom surface of measuring cylinder 1 vertically, connects firmly the lower surface that can be pressed on the form of barb workpiece 8 at the measurement gib head 5a that measures finger bottom.

In the periphery of the measuring cylinder of cavity 9 positions, be set with rotating spacer 4, on the madial wall of spacer, be provided with axial pass trough, rotate spacer and can make the steel ball in spring latch lock be incorporated in spacer interior (shown in Fig. 1 and Fig. 3) or eject in axial pass trough (shown in Fig. 2 and Fig. 4), so that measure finger, be in closure (shown in Fig. 1 and Fig. 3) or open on the diverse location of (shown in Fig. 2 and Fig. 4).
