Description

Technical Field

[0001] The utility model belongs to the technical field of aero-engine blade detection, and specifically relates to an on-line detection system for aero-engine blades. Background Art

[0002] Aero-engine blades are one of the key parts in aero-engines. They have complex shapes, harsh stress conditions, large size spans, and bear heavy loads. The external geometric dimensions of the blades determine the working performance of the engine, and their shapes and positions are closely related to the characteristic parameters of the engine, the pressure ratio of the compressor, the turbine speed, etc. Their quality and technical level directly affect the performance and life of the engine. Therefore, in the process of blade design, manufacturing, and detection, advanced detection technologies and management means are required to ensure that the quality and performance of the blades reach the best state. Therefore, the geometric detection of engine blades is particularly important.

[0003] At present, with the continuous improvement of aero-engine performance, new requirements have been put forward for the detection indexes after blade profile machining, especially for the requirements of detection accuracy and detection efficiency. To meet these requirements, advanced detection equipment and technologies are needed to accurately measure and evaluate the profile, curvature, surface roughness, etc. of the blade profile.

For example, it can be a fixed connection, a detachable connection, or an integral connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations. In the description of the embodiments, specific features, structures, materials, or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0072] The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0073] In the description of the present utility model, unless otherwise stated, the meaning of "a plurality" is two or more.

[0074] In some embodiments of the present application, an on-line detection system for aero-engine blades is proposed, which is used to realize automatic on-line detection and measurement of aero-engine blades.

[0075] For the convenience of transporting and measuring the aero-engine blade 200, the aero-engine blade 200 is clamped and fixed inside the fixture to form a blade fixture module. When measuring or transporting, the fixture and the aero-engine blade move synchronously as a module.

[0076] Specifically, the on-line detection system for aero-engine blades includes:

[0077] The incoming material conveying line 100 has a plurality of blade fixture modules equipped with clamps arranged side by side and conveyed on the incoming material line.

[0078] Through the incoming material conveying line 100, the incoming material conveying of the blade fixture module can be realized, and the blade fixture module is automatically conveyed to the measurement position that needs to be measured.

[0079] In some embodiments, the incoming material conveying line 100 can directly select a line body structure such as a belt conveyor in the prior art that can automatically convey materials.

[0080] The storage repository 300 is used to temporarily store the blade fixture modules conveyed by the incoming material conveying line.

[0081] The blade fixture modules conveyed through the incoming material conveying line 100 do not directly enter the automatic measuring device 400 for measurement, but are first placed at the position of the storage repository 300 for temporary storage and static placement to ensure the measurement accuracy of the subsequent aeroengine blades 200.

[0082] The automatic measuring device 400 is used to measure and detect the aeroengine blades 200.

[0083] In some embodiments, the automatic measuring device 400 is an existing coordinate measuring machine. The coordinate measuring machine includes a measuring body, and a measuring table 410 is arranged on the measuring body and a measuring module is arranged above the measuring table 410.

[0084] The measuring module includes a probe. Through the probe above it, it can be directly used to detect and measure relevant parameters of the aeroengine blades. The probe can select an existing star probe for measurement.

[0085] For example, during measurement, the probe can directly detect size parameters such as the profile, shroud, and root structure of the aeroengine blade 200.

[0086] The coordinate measuring machine can adopt the existing measuring machine structure, and the probe can also adopt the existing probe of the coordinate measuring machine.

[0087] The transfer robot 500 is arranged between the incoming material conveying line 100, the storage repository 300, and the automatic measuring device 400, and can transfer the blade fixture module between the incoming material conveying line 100, the storage repository 300, and the automatic measuring device 400.

[0088] The transfer robot 500 is arranged at a position between the incoming material conveying line, the automatic measuring device 400, and the storage repository 300 so that the distances between it and the incoming material conveying line 100, the storage repository 300, and the automatic measuring device 400 are all relatively close, facilitating its transfer of the blade fixture module.

[0089] In the on-line detection system for the aero-engine blade 200 in this embodiment, when in use, the blade fixture module to be detected and measured is sequentially conveyed by the incoming material conveying line body 100 to a position close to the transfer robot 500. The transfer robot 500 operates to clamp the blade fixture module from the incoming material conveying line body 100, and then transfers and places it on the storage repository 300 at a position on one side for storage. Then, the blade fixture module on the storage repository 300 is clamped to the automatic measuring device 400, and the automatic measuring device 400 measures and detects it. The aero-engine blade is transferred from the incoming material conveying line body 100 to the storage repository 300, and is clamped from the storage repository 300 for automatic measurement. The entire measurement process does not require manual participation in measurement, effectively avoiding the problems of large measurement errors and low measurement accuracy caused by manual participation.

[0090] In addition, in this embodiment, by assembling and clamping the aero-engine blade 200 inside the fixture for transfer and measurement, compared with the method of directly grasping the aero-engine blade 200 for measurement, it will not damage the aero-engine blade 200, and it is convenient for transfer. It not only ensures the measurement accuracy, but also realizes the protection of the aero-engine blade.

[0091] In some embodiments of the present application, the storage repository 300 includes:

[0094] The library base body 310 constitutes the support frame of the storage repository 300 and is used to play a supporting and bearing role.

[0095] By arranging storage racks 320 with different heights to realize the placement of blade fixture modules of different models.

[0096] The material detection sensor on each storage rack 320 can be used to detect whether a blade fixture module is placed on the storage rack 320.

[0097] The storage rack 320 includes a support frame body 321 and a bearing member 322 arranged on the support frame body 321;

[0098] The bearing member 322 is provided with an insertion part 323 for cooperating with the fixture and a fixture avoidance part 324 for avoiding the fixture.

[0099] In some embodiments, the support frame 321 includes a first support leg and a second support leg, and the bearing member 322 is connected between the first support leg and the second support leg for bearing and supporting the blade fixture module.

[0100] In some embodiments of the present application, the bearing member 322 is a bearing plate, and the insertion portion 323 is a jack, so as to facilitate the blade fixture module to be inserted and fixed in place.

[0102] In some embodiments of the present application, the transfer robot includes:

[0103] A robot body 510;

[0104] And a fixture gripper 520 detachably connected to the end of the robot body 510, and the fixture gripper 520 includes:

[0105] A gripper seat 521;

[0106] And a pneumatic gripper module 522 connected to the gripper seat 521, and there are 2 pneumatic gripper modules 522.

[0107] By providing 2 pneumatic gripper modules 522, one can be used while the other is in reserve, so as to improve the efficiency of loading and unloading.

[0108] The pneumatic gripper module 522 can be used to grip the blade fixture module.

[0109] Each pneumatic gripper module 522 includes:

[0110] A parallel opening and closing air gripper 5221;

[0111] And 2 pneumatic clamping members 5222, which are respectively connected to the parallel opening and closing air gripper 5221 and can be relatively opened or closed under the drive of the parallel opening and closing air gripper 5221.

[0112] The parallel opening and closing air gripper 5221 can directly adopt an existing structure, and the parallel opening and closing air gripper 5221 is used as a power source to drive the 2 pneumatic clamping members 5222 to act, open or close, so as to clamp the blade fixture module.

[0113] In some embodiments of the present application, a clamping notch 5223 is formed on the side of the pneumatic clamping member 5222, and the 2 pneumatic clamping members 5222 are oppositely arranged, and the clamping notches 5223 above them are oppositely arranged. When clamping the blade fixture module, the clamping notches 5223 of the 2 pneumatic clamping members 5222 are respectively clamped on the blade fixture module to realize the clamping and grasping operation of the blade fixture module.

[0114] In some embodiments, engaging limiting inclined surfaces 5224 are formed at the front side and the rear side of the engaging notch 5223 for engaging with the clamping operation portion 620 at the bottom of the fixture to limit the blade fixture module and prevent it from moving forward and backward and disengaging from the fixture gripper 520.

[0115] In some embodiments, to realize the connection between the fixture gripper 520 and the robot body 510, a first connection portion 5211 is further provided on the gripper seat 521.

[0116] The first connection portion 5211 is a first connection seat vertically provided on the gripper seat 521, and a groove is formed inside.

[0117] An insertion protrusion adapted to the groove is formed on the robot body 510, and the gripper seat 521 is connected by insertion fit of the groove and the insertion protrusion.

[0118] A first insertion hole is formed on the first connection seat, and a second insertion hole is formed on the insertion protrusion. After the first connection seat and the robot body 510 are inserted and fitted, they are further locked and positioned by inserting pins into the first insertion hole and the second insertion hole respectively.

[0119] The fixture base 600 constitutes the support body of the whole fixture and is used to bear and support the whole fixture.

[0120] The first clamping module 800 is fixedly assembled on the fixture base 600 and includes a first jaw module 810 for clamping and positioning one end of the engine blade 200.

[0121] The second clamping module 700 is slidably connected to the fixture base 600, is disposed opposite to the first clamping module 800, and a receiving space is formed therebetween.

[0122] It includes: a second jaw module 710 for clamping and positioning the other end of the engine blade 200.

[0123] The second clamping module 700 and the first clamping module 800 cooperate to realize the clamping and positioning of the engine blade 200.

[0124] The receiving space formed between the second clamping module 700 and the first clamping module 800 can be used to receive the engine blade 200.

[0125] When clamping and positioning the engine blade 200, the engine blade 200 can be placed inside the accommodating space between the second clamping module 700 and the first clamping module 800. Then, one end of the engine blade 200 is clamped and positioned by the second jaw module 710, and the other end of the engine blade 200 is clamped and positioned by the first jaw module 810 on the first clamping module 800, so as to realize the clamping and fixing of the engine blade 200, achieve the precise clamping and positioning of the engine blade 200, ensure the positioning effect of the engine blade 200, and further ensure the subsequent measurement accuracy of the engine blade 200.

[0126] The second clamping module 700 is connected to the fixture base 600 in a slidable manner. By sliding the second clamping module 700 relative to the first clamping module 800, the size of the accommodating space can be changed.

[0127] When it is necessary to clamp and position a larger-sized engine blade 200, the second clamping module 700 can be slid outwards to increase the distance between the first clamping module 800 and the second clamping module 700, so as to keep the larger-sized engine blade 200 clamped and fixed.

[0128] When it is necessary to clamp and position a smaller-sized engine blade 200, the second clamping module 700 can be slid inwards to reduce the distance between the first clamping module 800 and the second clamping module 700, so as to keep the smaller-sized engine blade 200 clamped and fixed. By the slidability of the second clamping module 700, the adaptation to different engine blades 200 is realized, and the versatility of the whole fixture is improved.
