Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to an automatic blade profile detection device. Background Art

[0002] During the production and processing of blades, they need to strictly comply with standard size specifications, including the detection and verification of blade contours to achieve automated detection of blades. The usual detection method is to cooperate with the positioning cylinder and contact the measured object through the pressure sensor to cause the pressure sensor to deform. The amount of deformation is converted into length and width values ​​through data calculation. The numerical reporting system is compared with the pre-set value. When the comparison is within the set range, it is defined as a good product and put into a normal collection box. If it exceeds the range, confirm which type of abnormality (such as length abnormality, thickness abnormality, etc.) is automatically placed in the corresponding abnormal product collection box to complete the detection.

[0003] In the use of existing automatic blade profile detection equipment, since the blade is fixed to the carrier plate by pneumatic adsorption, the length and width of the blade can be detected during the movement of the carrier plate. However, the rear end face of the blade is difficult to detect in one detection, and a rotating mechanism needs to be added to realize the rotation adjustment of the blade, which increases the complexity of the detection. The secondary detection increases the detection time, reduces the detection efficiency of the blade, and the use effect is not good.

[0004] In addition, during use, the existing automated blade profile detection equipment requires adjustment and vacuum adsorption when the blade is placed on a carrier plate to achieve effective positioning before blade detection. However, the positioning and adjustment effect of the blade is poor during actual operation, and there is a lack of effective positioning calibration and fine-tuning during the blade transportation process, which cannot ensure that the contour surface of the blade can effectively contact the pressure sensitive sensor, resulting in the detection data not being consistent with reality, affecting the detection effect.

[0005] On the other hand, in the use of existing automated blade profile detection equipment, the surface of the pressure sensor needs to frequently contact the blade profile surface, and frequent and large-scale detections cause the surface of the pressure sensor to be slightly worn. Although the function of the pressure sensor remains normal, the slight change in the thickness of the pressure sensor directly affects the detection of the blade profile, resulting in errors in blade detection and poor use effect. Summary of the invention
