Description

Technical Field

[0001] The invention relates to the technical field of turbine blade detection, and in particular to a turbine blade synchronization and coordination detection device. Background Art

[0002] Currently, turbine blade inspection technology mainly relies on traditional manual inspection and fixed inspection equipment. These methods usually require operators to manually adjust the equipment at each inspection location, which is inefficient and prone to human errors. Traditional inspection equipment often cannot achieve multi-angle and full coverage inspection of turbine blades, especially on blades with complex geometric shapes, which can easily lead to missed inspections in certain areas, thus affecting the comprehensiveness and accuracy of the inspection.

[0003] In the field of automated inspection, some inspection systems based on image processing and sensing technology have been applied to the quality assessment of turbine blades. These systems generally rely on multiple fixed cameras to perform inspections from different angles. However, the layout and viewing angle of fixed cameras are limited, making it difficult to achieve a comprehensive scan of turbine blades. In addition, the reflectors or optical systems used in the prior art are often not flexible enough during the adjustment process and cannot quickly adapt to turbine blades of different models and sizes, resulting in a cumbersome and time-consuming inspection process.

[0004] In addition, many existing detection equipment lack intelligence and automation, have high operational complexity, and usually require professional personnel to debug and operate; for the synchronous and coordinated detection of turbine blades, the existing technology has not yet achieved flexible adjustment in multiple dimensions, so when faced with turbine blades of different models and shapes, the adaptability of existing equipment is insufficient.

The reflector array 301 is fixedly arranged above the fixed frame 3. The fixed frame 3 is fixedly connected to the detection table 2 through the rotating table. The first ring shaft 101, the second ring shaft 102 and the fixing frame 3 are arranged in parallel, and the first ring shaft 101 is higher than the horizontal position of the second ring shaft 102, and the second ring shaft 102 is higher than the horizontal position of the fixing frame 3; The outer edge of the second ring shaft 102 is provided with external teeth 1024, and the rotation power mechanism 1023 includes a gear, and the gear is meshed with the external teeth 1024, so as to drive the second ring shaft 102 to rotate; The inner diameter and / or outer diameter of the first ring shaft 101 and the second ring shaft 102 are different, so that the connecting straight lines formed by the plurality of first locking mechanisms 1011 and the plurality of second locking mechanisms 1021 form a uniform inclination angle with the vertical line of the ground; The positioning ring slider 103 is slidably connected to the groove 1022 provided on the second ring shaft 102 through a sliding member. The positioning ring slider 103 is connected to the second ring shaft 102 from both ends at the top and bottom. The bottom connection part provides support force and a sliding connection matching member, and the upper end provides downward pressure and a sliding connection matching member for the second ring shaft 102. Under the cooperation of the upper and lower parts, the second ring shaft 102 and the positioning ring slider 103 form a sliding connection relationship, so that the second ring shaft 102 can rotate concentrically under the action of external force; The center of the first locking mechanism 1011 is fixed to the first ring shaft 101 through a rotatable structure, so that the first locking mechanism 1011 can rotate around the center by a certain angle, and the angle is preferably 15 degrees to the left and 15 degrees to the right; The gear is meshed with the external teeth 1024 fixedly disposed on the second ring shaft 102 to drive the second ring shaft 102 to rotate concentrically; The center of the second locking mechanism 1021 is fixed to the second ring shaft 102 through a rotatable structure, so that the second locking mechanism 1021 can rotate around the center by a certain angle, preferably 15 degrees to the left and 15 degrees to the right. When the rotating power mechanism 1023 rotates, the second ring shaft 102 rotates accordingly; When the positioning ring slider 103 and the rotating power mechanism 1023 are both in sliding cooperation with the bracket 1 , the horizontal heights of the positioning ring slider 103 , the rotating power mechanism 1023 and the second ring shaft 102 can be synchronously adjusted through this structure.

[0022] like Figure 1 , Figure 5 and Figure 6 As shown, each reflector on the reflector array 301 includes an angle adjuster, which is used to synchronously adjust the reflectors on the reflector array 301, and the angle adjuster is composed of three support rods 3011; wherein, the three support rods 3011 are arranged in a certain triangular structure, and each support rod 3011 is controlled by a power mechanism to control the specific position of its lifting or falling back, and based on this structure, the reflector can be made to reflect at multiple angles, and by synchronously controlling the support rods 3011 at corresponding positions on the reflector array 301, the reflection angle of all the reflectors on the reflector array 301 can be synchronously adjusted to achieve the reflection requirements.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the fixed frame 3, the first ring axis 101, the second ring axis 102 and the testing platform 2 are arranged concentrically, the bracket 1 is a ring structure, and a base 104 is arranged inside the bracket 1. The workpiece 4 is placed on the upper end of the testing platform 2, and the lower end of the testing platform 2 is fixedly installed on the upper surface of the base 104. The two ends of the base 104 are respectively fixed to the inner side walls of the bracket 1; wherein, the testing platform 2 includes a lifting mechanism and a rotation power mechanism, the lifting mechanism is used to adjust the height of the testing platform 2, and the rotation power mechanism is used to drive the testing platform 2 to rotate relative to the base 104 in a centered manner. Secondly, the first ring axis 101, the second ring axis 102, the testing platform 2 and the fixed frame 3 are also parallel to each other. After the workpiece 4 is placed on the testing platform 2, it should also be parallel to the above-mentioned mechanism and also in a concentric position.

[0024] like Figure 3 As shown, the rotating power mechanism 1023 and the rotating table are controlled by the same electronic control system. In the figure, the middle figure is the initial state of the first ring shaft 101 and the second ring shaft 102, and the left and right sides are state diagrams after the rotating power mechanism 1023 drives the second ring shaft 102 to rotate and swing to the left and right respectively. It should be noted that this swing angle is limited by the mechanical structure and the inner diameter of the ring, and there may be certain limitations on the swing angle change, but this limitation can be achieved by adjusting the fixing method of the first locking mechanism 1011 and the second locking mechanism 1021.

[0025] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the tail end of the camera 5 is fixed on the first locking mechanism 1011, the head end of the camera 5 is fixed on the second locking mechanism 1021, the lens of the camera 5 is sleeved with a light source, the side of the fixed frame 3 is fixedly provided with a light source, the rotating table is fixedly provided with a light source, and all the light sources are multi-directional partitioned light sources; wherein, in some complex turbine blade detection processes, the camera 5 needs to adjust the shooting angle, in order to ensure that the camera 5 and the reflector array 301 do not shift in position during the detection process, the reflector array 301 needs to cooperate with the rotation of the second ring shaft 102 to rotate synchronously at a certain conversion ratio, at this time, the rotating power mechanism 1023 and the rotating table are placed under the same electric control system, if any one of them rotates, the other will rotate synchronously at a certain conversion ratio, and the synchronous coordination function is completed at one time; there are also multiple light source irradiation modes, firstly, the light source can be set on the camera 5, and the directional uniform fill light is performed by the different directions of the head of the camera 5, and the light source can also be set on the rotating table or any side of the fixed frame 3; in addition, the light source can be a partitioned light source to achieve a better detection effect.

[0026] The working principle of the present invention is as follows: when in use, first, the turbine blade is placed at the position of the workpiece 4, and then the height of the detection platform 2 can be adjusted according to the detection requirements through the lifting mechanism, so that the turbine blade is in a suitable detection position, and the self-rotation power mechanism can drive the detection platform 2 to rotate relative to the bottom platform 104, driving the turbine blade to rotate, so as to detect the turbine blade from different angles; Then, the rotating power mechanism 1023 inside the bracket 1 is meshed with the outer teeth 1024 on the outer edge of the second ring shaft 102 through gears, thereby driving the second ring shaft 102 to rotate concentrically. The positioning ring slider 103 is slidably connected to the grooves 1022 at the upper and lower ends of the second ring shaft 102 through the sliding members at the upper and lower ends, which not only provides support force and downward pressure for the second ring shaft 102, but also enables the second ring shaft 102 to rotate concentrically under the action of external force (driving force of the rotating power mechanism 1023). At the same time, the positioning ring slider 103 and the rotating power mechanism 1023 are both slidably connected to the inside of the bracket 1, and the horizontal heights of the positioning ring slider 103, the rotating power mechanism 1023 and the second ring shaft 102 can be synchronously adjusted to meet the height requirements of different detection scenarios. The rotatable design allows the angle of the camera 5 to be further adjusted when the second ring shaft 102 rotates, and within the swing angle range limited by the mechanical structure and the inner diameter of the ring, the swing angle range can be expanded by adjusting the fixing method of the first and second locking mechanisms 1021; Furthermore, by synchronously controlling the support rods 3011 at corresponding positions on the reflector array 301, all reflectors can be made to synchronously adjust the reflection angle to achieve light reflection at different angles, thus meeting the specific requirements for light reflection during detection. In addition, in certain complex detection scenarios, in order to ensure that the camera 5 and the reflector array 301 do not shift in position, the reflector array 301 needs to rotate synchronously with the rotation of the second ring shaft 102 at a certain conversion ratio, and the rotating power mechanism 1023 and the rotating table are placed under the same electric control system. When the rotating power mechanism 1023 drives the second ring shaft 102 to rotate, the rotating table can drive the reflector array 301 to rotate synchronously at a corresponding ratio, thus completing the synchronous coordination function; Finally, when the second ring shaft 102 rotates under the drive of the rotating power mechanism 1023, the camera 5 will change its position and angle accordingly. At the same time, the rotatable characteristics of the first and second locking mechanisms 1021 further increase the adjustment range of the shooting angle of the camera 5, so that it can shoot the turbine blades on the test platform 2 from different angles and obtain multi-directional image information; The light source can illuminate the turbine blades from different directions and different areas. When inspecting complex turbine blades, the light intensity, color and other parameters of the light source in the corresponding area can be flexibly adjusted according to the shape, material and inspection focus of different parts of the turbine blades, so as to provide sufficient and appropriate light conditions for camera 5 to highlight the detailed features of the turbine blades, so as to achieve better inspection effects and improve the accuracy and reliability of inspection. The image information obtained by camera 5 can be used for subsequent inspection and analysis of the turbine blades to determine whether the turbine blades have defects and other problems.
