Description

Technical Field

[0001] The invention belongs to the field of machining technology, and in particular relates to a device for measuring the depth of an annular groove. Background Art

[0002] During the machining process, parts with annular grooves and cross-section grooves are often encountered. The groove depth accuracy level of these parts is high and the grooves are relatively narrow. Usually, the detection method of this type of groove considers using a depth gauge or a vernier caliper for measurement, but for narrow grooves, the vernier caliper and depth gauge have large feet and are not suitable for measuring narrow grooves. In addition, the measurement tolerance band of the vernier caliper and depth gauge is 0.1, which cannot meet the workpiece accuracy level requirement of less than 0.01. For CNC vertical lathes, a measuring table can be used to measure the groove depth of the annular groove, but only the size on the center busbar of the worktable is closest to the theoretical size. The existing table frame makes it difficult to ensure that the machine tool is measured on the center busbar of the worktable, so the measurement error is large and random. We need a convenient and convenient detection device to accurately measure various groove depths. Summary of the invention
