Therefore, the technical scheme of the utility model be, an excircle measuring device with adjustable is equipped with the base, is equipped with a supporting bench on the base, and a supporting bench lower extreme is equipped with the tight screw in top, and the tight screw in top passes through the screw thread to be installed on the base, is equipped with the gauge head support on the base, installs the gauge head on the gauge head support, still is equipped with the gauge head support on the base, is equipped with the gauge head on the gauge head support.

Preferably, the base is provided with a mounting unthreaded hole, the measuring head support is placed in the mounting unthreaded hole of the base, the measuring head support is fixed by arranging a jackscrew at a corresponding position on the base, the base is provided with two measuring heads, and the two measuring heads are vertically distributed.

Preferably, the measuring head is in threaded connection with the measuring head support, and the measuring head is further provided with a locking nut.

Preferably, the meter head support is provided with a double countersunk hole at the joint of the meter head support and the base, the meter head support is provided with a tensioning opening, the meter head is arranged in the tensioning opening, and threaded holes are formed in two sides of the tensioning opening.

Preferably, a sealing ring is arranged between the base and the supporting platform.

The beneficial effects of the utility model are that, place the work piece that awaits measuring on a supporting bench, also can establish the work piece cover on a supporting bench, position alignment through the gauge head with the work piece, the reuse gauge head is measured the work piece, the work piece can be rotatory on a supporting bench, can realize the full circumference measurement of work piece, and can adjust a supporting bench's height through the holding screw of adjustment supporting bench below, and then realize the measurement of the different high positions of work piece, the device has both guaranteed the size precision of work piece, can detect whether the outward appearance is defective again, can not cause the deformation influence to the work piece, the work piece quality has been guaranteed, the production efficiency is improved, the simultaneous measurement excircle and highly can adjust in order to detect the not product of equidimension.
