Description
Technical Field
The invention belongs to the technical field of measuring equipment, and relates to a diameter measuring device for an annular groove.
Background
In machining production, some large-scale workpieces are composed of two concentric rings with different sizes, such as an annular groove, detection and measurement of the annular groove workpiece are generally carried out by checking tools such as a go-no go gauge and a groove width gauge at present, but the go-no go gauge and the groove width gauge of the existing measuring tool can only check that the groove width of the workpiece is qualified and unqualified, cannot measure the actual value of the groove, and brings difficulty to adjustment, and measuring tools such as a vernier caliper cannot meet the actual measurement requirement of the annular groove workpiece due to structural limitation.
In order to solve the above-mentioned problem that the ring channel diameter measurement exists, the utility model develops a measuring device who is exclusively used in ring channel diameter.
