Description

Technical Field

[0001] The utility model belongs to the technical field of compressor blade stripe defect detection, and in particular relates to a compressor blade stripe defect detection tool. Background Art

[0002] The compressor is a component of a gas turbine engine that uses high-speed rotating blades to work on the air to increase the air pressure. The front end of the compressor impeller blade is curved and is called the guide wheel. Its function is to guide the gas into the working impeller without impact, reducing the impact loss of the airflow.

[0003] After the compressor blades are processed, they need to be inspected for stripe defects on their surfaces. Existing inspection tools cannot inspect compressor blades of different specifications and have a small scope of application. This phenomenon has become a problem that needs to be urgently solved by people in this field. Utility Model Content

[0004] The utility model aims to provide a compressor blade stripe defect detection tool to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a compressor blade stripe defect detection tooling comprises a bottom plate, support plates are fixed on both the left and right sides above the bottom plate, and a fixing rod is fixed between the two support plates;

[0006] A placement block is fixedly installed in the middle of the upper part of the bottom plate;

[0007] A telescopic rod is fixedly installed at the middle bottom of the fixing rod, and a camera is arranged at the bottom of the telescopic rod. The camera is used to photograph the surface of the compressor blade to determine whether there is a stripe defect.

[0008] The utility model further describes that a magnetic ring is fixedly installed at the bottom of the fixing rod, the camera is located in the middle of the magnetic ring, and telescopic rods are fixed on both left and right sides of the bottom of the magnetic ring;

[0009] The bottom end of the telescopic rod is fixedly connected to the upper surface of the camera.

[0010] The utility model further describes that a bearing seat is connected between the bottom end of the telescopic rod and the upper surface of the camera.

[0011] Compared with the prior art, the beneficial effects achieved by the utility model are as follows: the compressor blade stripe defect detection tooling adopted by the utility model, the operator places the compressor blade on the mounting block, and the height of the compressor blade is different according to the specifications of the compressor blade. At this time, the operator presses the telescopic rod to extend and contract, and the telescopic rod drives the camera to move up and down, thereby controlling the distance between the camera and the compressor blade, so that the camera can fully capture compressor blades of different specifications, avoiding the problem of incomplete captured images due to the close distance between the camera and the compressor blade, affecting the judgment of stripe defects. When the operator adjusts the distance between the compressor blade and the camera through the telescopic rod, the camera pulls the telescopic rod to extend or contract. When the adjustment is completed, the magnetic attraction generated by the magnetic ring can fix the telescopic rod to the adjusted length, thereby preventing the camera from moving downward due to its own weight after the adjustment, and playing a role in fully fixing the camera, thereby ensuring the stripe defect detection effect.

[0017] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 , the utility model provides a technical solution: a compressor blade stripe defect detection tooling, comprising a bottom plate 1, support plates 2 are fixed on both the left and right sides above the bottom plate 1, and a fixing rod 3 is fixed between the two support plates 2;

[0019] A placement block 4 is fixedly installed in the middle of the upper part of the bottom plate 1;

[0020] A telescopic rod 5 is fixedly installed at the middle bottom of the fixed rod 3. A camera 6 is arranged at the bottom of the telescopic rod 5. The camera 6 is used to photograph the surface of the compressor blade to determine whether there is a stripe defect.

[0021] The operator places the compressor blade on the mounting block 4. The height of the compressor blade varies according to the specifications of the compressor blade. At this time, the operator presses the telescopic rod 5 to extend and contract, and the telescopic rod 5 drives the camera 6 to move up and down, thereby controlling the distance between the camera 6 and the compressor blade, so that the camera 6 can fully capture compressor blades of different specifications, avoiding the problem that the distance between the camera 6 and the compressor blade is too close, resulting in incomplete images and affecting the judgment of stripe defects.

[0022] A magnetic ring 7 is fixedly mounted at the bottom of the fixing rod 3, a camera 6 is located in the middle of the magnetic ring 7, and telescopic rods 8 are fixed on both left and right sides of the bottom of the magnetic ring 7;

[0023] The bottom end of the telescopic rod 8 is fixedly connected to the upper surface of the camera 6;

[0024] When the operator adjusts the distance between the compressor blades and the camera 6 through the telescopic rod 5, the camera 6 pulls the telescopic rod 8 to extend or contract. When the adjustment is completed, the magnetic attraction force generated by the magnetic ring 7 can fix the telescopic rod 8 at the adjusted length, thereby preventing the camera 6 from moving downward due to its own weight after the adjustment, and fully fixing the camera 6, thereby ensuring the stripe defect detection effect.

[0025] A bearing seat 9 is connected between the bottom end of the telescopic rod 5 and the upper surface of the camera 6;

[0026] During the process of detecting streak defects, in order to facilitate all-round detection of the surface of the compressor blade, the operator can rotate the camera 6 through the bearing seat 9, so as to take pictures in different directions and improve the detection quality.
