Technical Field

The invention belongs to the technical field of machining, and particularly relates to a device for measuring the depth of a ring groove.

Background

During machining, parts with ring grooves and cross-sectional grooves are often encountered, which have a high level of groove depth accuracy and narrow grooves. Generally, a depth gauge or a vernier caliper is considered to be used for measuring the groove, but for a narrow groove, the foot of the vernier caliper or the foot of the depth gauge is large, so that the method is not suitable for measuring the narrow groove, and the measuring tolerance zone of the vernier caliper and the foot of the depth gauge is 0.1, so that the requirement of the workpiece precision grade is not less than 0.01. For a numerical control vertical lathe, a measuring meter can be used for measuring the groove depth of the ring groove, but only the dimension on the central bus of the workbench is closest to the theoretical dimension, and the existing meter frame is difficult to ensure that the measuring meter of the machine tool is measured on the central bus of the workbench, so that the measuring error is large and the randomness is large. What is needed is a convenient and fast detection device for accurately measuring various groove depths.
