Straight hole internal O-type groove depth detecting device

Abstract

The invention provides a straight hole internal O-type groove depth detecting device, and relates to the technical field of depth detection. The detecting device comprises a first-stage hole depth detecting assembly and a second-stage hole depth detecting assembly. The first-stage hole depth detecting assembly is used for detecting the depth of a first-stage hole of an O-type groove and is a go-no-go block with a first surface and a second surface. The first surface is used for making contact with the fat face of the upper side of the first-stage hole of a to-be-detected workpiece. The secondsurface is used for making contact with the fat face of the lower side of the first-stage hole of the to-be-detected workpiece. The distance between the first surface and the second surface is the depth of the first-stage hole. The second-stage hole depth detecting assembly is a gauge-carrying depth detecting tool for detecting the depth of a second-stage hole of the O-type groove. By means of thedepth detecting device, the detecting efficiency of personnel can be effectively improved, detecting cost is reduced, the measurement result precision is ensured, and the depth detecting device has the advantages of being convenient to use and maintain, low in fault rate, low in cost, high in efficiency, accurate in detection, long in service life, convenient and rapid to use and the like.

Description

technical field [0001] The invention relates to the technical field of depth detection, in particular to an O-shaped groove depth detection device in a straight hole. Background technique [0002] Since the straight hole of the workpiece in the foundry industry has the shape of the inner O-shaped groove during the production or processing process, in order to ensure that the depth of the inner O-shaped groove meets the technical requirements of the drawing during the production or processing of the product, it is necessary to adjust the depth of the inner O-shaped groove of the casting product. On-site random inspection or batch inspection is carried out on the size to ensure that the size meets the requirements. [0003] In the existing technology, methods such as micrometers, calipers, calipers, and height gauges are generally used for detection, but they are not suitable for the depth detection of the O-shaped slot in the straight hole. The depth of the O-shaped slot in t...

[0003] In the existing technology, methods such as micrometers, calipers, calipers, and height gauges are generally used for detection, but they are not suitable for the depth detection of the O-shaped slot in the straight hole. The depth of the O-shaped slot in the straight hole can be measured using three coordinates The measuring machine is used for inspection, and it is difficult to pick points for workpieces with small 0-shaped grooves, and this method is even more unreasonable in batch acceptance. It has the following disadvantages: the three-coordinate measuring machine has high detection costs and low detection efficiency , The production site cannot be used
