Description

Technical Field

[0001] The utility model relates to the technical field of machining detection, in particular to a CNC machined part precision detection device. Background Art

[0002] The CNC machined parts precision detection device is usually composed of a CNC probe and corresponding detection software. This device is widely used in mechanical processing, automobile manufacturing, aerospace and other fields. The purpose is to perform precision detection on parts processed by CNC machine tools to ensure the processing quality, and the CNC probe is the core part of the CNC machined parts precision detection device. It is a high-precision position sensor that can accurately detect parameters such as the position and size of the workpiece. The probe is usually connected to the CNC machine tool and measured through program control or manual operation. During the measurement process, the probe will detect the surface of the workpiece in contact or non-contact, and transmit the measurement results to the detection software through the data interface for processing and analysis.

[0003] Common detection devices generally clamp the workpiece first and then detect its surface with a probe. However, since the workpiece is clamped horizontally in this method, when performing roughness detection on some inner holes, inclined grooves or inclined holes, the workpiece needs to be removed first, and then the angle of the workpiece needs to be adjusted before clamping and detecting. As a result, the entire process requires multiple clamping, which not only reduces the detection speed, but also requires continuous alignment during repeated disassembly and assembly, making the detection process cumbersome and unable to meet the work requirements of workpiece detection. For this reason, a CNC machined part precision detection device is proposed. Utility Model Content
