Technical Field

The utility model belongs to the technical field of measuring tool, concretely relates to degree of depth measuring device based on digital display tongue.

Background

In the daily detection of mechanical parts, a vernier caliper with a depth gauge or a special depth gauge is generally used for measurement. Because the top of the measured part needs to be provided with a plane as a comparison reference, and the vernier caliper with the depth gauge can only measure a small-span hole, groove or platform because the end part of the caliper body is used as a measurement reference plane; although the special depth gauge can measure holes or grooves with large span, the holes or grooves and the platforms with large span still need other auxiliary tools to complete the measurement; in addition, for the tested parts which have complex structures and form shelters or have no reference plane on the top, the measurement can be completed by other auxiliary tools, and the measurement value can be obtained by calculation, so that the measurement process is complex. In the prior art, although an auxiliary measuring head is additionally arranged on a measuring claw of a height gauge, a workbench is used as a reference, the auxiliary measuring head is inserted into a hole or a groove of a measured part to complete measurement, and the distance between the gauge body of the height gauge and the workbench can be changed and the height of the measuring head relative to the workbench can be adjusted by vertically moving the measuring head and horizontally moving the measuring head up and down, so that the height gauge is suitable for measurement of different spans and depths. However, it should also be seen that, because the auxiliary measuring head can only move horizontally and vertically, when measuring deep holes of large parts, the measuring head can only be extended into the upper space of the part to be measured by adjusting the height of the measuring jaw of the height gauge, then vertically raising the measuring head, then lowering the measuring head to extend into the measuring part, and finally moving the measuring jaw of the height gauge up and down to record the descending value of the measuring head and the value of the measuring jaw, and the measurement can be completed through calculation, so that the measuring process is complicated and the efficiency is low. Of course, the whole height gauge and the auxiliary measuring head on the height gauge can be lifted, then the auxiliary measuring head enters the part, the measuring claw of the height gauge is moved up and down, the size of the measuring part relative to the workbench is directly obtained by reading the moving value of the measuring claw, although the measuring process is simple, the height gauge for measuring the large part is heavy, the lifting labor intensity is high, the height gauge is easy to collide with the part to be measured, and the safety is low.
