Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, and particularly relates to an automatic swing device for on-line detection. Background Technique

[0002] When numerically controlled machine tools perform on-line detection of products and measure workpieces or tools, in some cases, it is necessary to adjust out the measuring probe to the measuring position during measurement. After the measurement is completed, the measuring probe is removed to perform subsequent processing work. This not only meets the measurement requirements but also avoids the interference of the measuring probe on the tool processing path during the processing process;

[0003] It is found that the publication number is: CN216955872U, which discloses an ultrasonic straight probe for detecting new forgings. In this technology, "an ultrasonic straight probe for detecting new forgings includes a housing, a probe wire, and a crystal. The probe wire is inserted into the housing, and the crystal is located inside the housing. It also includes a contact block, which is detachably connected to the housing. One side of the contact block is closely attached to the surface of the crystal, and the contact block has a workpiece contact surface, and the workpiece contact surface is located outside the housing" and other technical solutions, and has technical effects such as "the setting of the contact block increases the wear resistance of the overall probe, the contact block is convenient to replace, and the same set of probe equipment can correspond to contact blocks of various materials and specifications, increasing the versatility and practicality";

[0004] The measuring probe may encounter the problem of repeat positioning error during the adjustment process, which means that after experiencing multiple movements, the probe may not be able to accurately return to its original or set position. This inaccuracy of positioning will directly affect the measurement accuracy and reliability. Content of the Utility Model
