Summary of the invention:

The purpose of this utility model provides a kind of adjustable female cone gauge that can accurately measure metric taper hole tapering, utilizes it can more convenient and accurately measure the tapering of conical bore on the part, so that can process qualified conical bore.

The technical solution adopted in the utility model is: a kind of adjustable female cone gauge, comprise blade, slide block, amount head, latch mechanism, and blade slides and is loaded in the groove of slide block, is provided with lock-screw between the two; Latch mechanism is made of locking knob, latch segment, circle cover, latch segment one end is a screw rod, the other end is a cylinder, at cylindrical end a hole is arranged, and the direction and the cylinder in hole are perpendicular, circle puts the hole of two square crossings, the screw rod end of latch segment is loaded in the hole above the slide block side boss, is connected with locking knob, and circle is sleeved on the cylindrical end of latch segment, the amount head is loaded in the hole of circle cover and latch segment, and locks by locking knob.

Compare with various bevel protractors with Mohs of the prior art awl gauge, obvious characteristic of the present utility model is by the distance between the angle of adjusting two amount heads and two slide blocks, just can measure the female cone of different taperings and different-diameter.The following occasion of its particularly suitable:

1. use when grinding has the cover parts of conical bore on grinding machine, can more convenient and accurately measure the tapering of taper hole,, and guarantee crudy easily so not only for the operator provides great convenience with adjustable female cone gauge.

2. adjustable female cone gauge is equally applicable to measure the tapering that on engine lathe turning has the part of taper hole.

3. adjustable female cone gauge can also be used to checking the tapering of the cover parts with conical bore.
