Depth gauge checking tool

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

technical field [0001] The invention relates to the field of measuring instruments, in particular to a depth gauge inspection tool. Background technique [0002] Artifact 2, such as image 3 As shown, the data of the depth 9 of the hole parts with grooves at the bottom of the step hole is generally measured by a three-coordinate measuring instrument. Although the measurement accuracy is high, the measurement process is complicated and time-consuming, and is not suitable for the detection of mass production of workpieces. Contents of the invention [0003] In view of the above problems, the present invention provides a depth gauge inspection tool, which can measure the distance from the groove end face to the hole end face of hole parts with grooves at the bottom, while ensuring the measurement accuracy, the measurement is simple and fast, and the work efficiency is high . [0004] Its technical solution is as follows, the depth gauge inspection tool, which includes a dial...
