Abstract

The invention provides a depth gauge checking tool. The depth gauge checking tool comprises a micrometer gauge and a calibration block and is characterized in that the checking tool comprises a measuring body, a clamping device and an ejector rod, the measuring body is installed on a stepped surface of a part to be measured, a guide hole is arranged at the center of the measuring body, the micrometer gauge is inserted into the clamping device and fixed at the end of the guide hole of the measuring body, the ejector rod is installed in the guide hole, a measuring block is rigidly connected with the bottom of the ejector rod, a measuring sheet is rigidly connected with the bottom of the measuring block, and one end of the measuring sheet protrudes out of the outline of the bottom end of the ejector rod. By means of the depth gauge checking tool, the distance between an end face of a groove and an end face of a hole of a hole type part which is provided with the groove at the bottom end can be measured, the measuring accuracy can be guaranteed, simultaneously the measuring is simple, convenient and rapid, and the work efficiency is high.

Description

The depth gauge cubing

Technical field

The present invention relates to the surveying instrument field, be specifically related to the depth gauge cubing.

Background technology

Workpiece 2 as shown in Figure 3, is measured the data normal operation three-coordinates measuring machine of its degree of depth 9 of the fluted hole type parts of stepped hole bottom band, although measuring accuracy is high, measuring process is complicated, time-consuming, is not suitable for the detection that batch workpiece is produced.

Summary of the invention

For the problems referred to above, the invention provides the depth gauge cubing, it can measure its groove end face of hole type parts of bottom with groove to the distance of hole end surface, when guaranteeing measuring accuracy, measure easy, quick, high efficiency.

Its technical scheme is such, the depth gauge cubing, it comprises clock gauge and calibration block, it is characterized in that: it comprises measures body, clamping device and push rod, described measurement body is installed on its step surface of part to be measured, described measurement body center has pilot hole, described clock gauge is plugged in described clamping device and is fixed in described measurement body pilot hole end, described push rod is installed in the described pilot hole, the measurement piece is rigidly connected bottom the described push rod, described measurement piece bottom rigid connecting is connected to the measurement sheet, and described measurement sheet one end protrudes from push rod bottom profile.

It is further characterized in that:

Described pilot hole center section has spacing hole, and described push rod top is provided with confined planes, between described confined planes and its bottom end face of described spacing hole, described top stem casing is equipped with spring;

Described clamping device comprises grip block and clamping ring, and described clock gauge is plugged in grip block, also fastening with wheel flange.

It further is characterised in that:

It also comprises spacer pin, its vertical side opening limited location groove of described push rod, described measurement body side surface, have adjustment hole perpendicular to described measurement body direction, the described pilot hole of described adjustment hole UNICOM and corresponding described stopper slot, described spacer pin is plugged in described its adjustment hole of measurement body, the one end inserts its stopper slot of described measuring staff.

After adopting the present invention, its beneficial effect is: measurement is shown consideration for and is closed the workpiece for measurement surface, inside parts groove to be measured is blocked in measurement sheet protruding end, can measure its groove end face to the distance of hole end surface, detect easyly, quick, the fastening push rod of adjusting screw is convenient to final reading, simultaneously, by measuring with calibration block first, and then measure part to be measured, avoided the situation of clock gauge band error, guarantee measuring accuracy, and high efficiency.
