Description

Technical Field

[0001] The present invention relates to the technical field of engine blade detection, and in particular to a roughness detection device and a detection method for machining aircraft engine blades. Background Art

[0002] The working principle of the roughness detection equipment is mainly based on the stylus method. During the measurement process, the movable probe above the instrument contacts the surface of the test sample and moves along a predetermined path. During the movement of the probe, the tester will measure the height change of each contact point and record this data. By processing this data, the tester can calculate the roughness parameters of the sample surface.

[0003] In the existing technology, the surface roughness detection of aircraft engine blades generally relies on contact measurement technology. This technology uses a high-precision surface roughness meter, whose probe is designed to achieve physical contact with the surface of the blade being measured. During the measurement process, the probe moves along a preset scanning path on the surface of a single blade to accurately capture the microscopic geometric feature data of the part surface. These captured data are then analyzed by the processing system inside the roughness meter, and finally the instrument will output quantitative surface roughness measurement results based on specific algorithms and standards.

[0004] Chinese patent application CN217716370U discloses a surface roughness detection device for a single blade of an aircraft engine: a staff member places a single blade of an aircraft engine between a group of clamps, and rotates the tightening knobs respectively. The tightening knobs rotate on the threaded rods, driving the clamps to approach each other, fixing the clamps, turning on the servo motor, and the output end of the servo motor drives the rotating disk to rotate, and the rotating disk drives the guide teeth on one side to rotate. When the guide teeth and the driving teeth are engaged, the driving teeth drive the annular plate to rotate, and the annular plate drives the hinged rod to rotate an angle, and the electric telescopic rod is turned on. The electric telescopic rod can drive the roughness detector to fit the single blade of the aircraft engine to be tested to perform roughness detection on it. When the guide teeth and the driving teeth are engaged again, the roughness detection can be performed on the next single blade of the aircraft engine.

[0005] The above patents and prior art also have the following defects: The above-mentioned roughness detection device requires the staff to manually turn multiple fastening knobs to drive the clamping parts closer to each other. This process not only significantly prolongs the operation cycle, but is also easily affected by human factors, resulting in instability and fluctuations in operating efficiency. After all the workpieces on the rotating disk have been inspected, the servo motor needs to be stopped, and the staff needs to manually release the clamping state of all the workpieces one by one, remove the inspected workpieces one by one, and manually place new workpieces to be inspected on the rotating disk, and then manually clamp them one by one again. Manually releasing the clamping, removing the workpieces, placing new workpieces and re-clamping all take time. These steps will extend the inspection cycle of each round of workpieces.

[0006] Therefore, the present application provides a roughness detection device and an inspection method for aircraft engine blade processing to meet the needs. Summary of the invention

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example: Reference Figure 1-Figure 8 A roughness detection device shown in the figure includes: an equipment housing 1, an opening 101 is opened on the front side of the equipment housing 1, and a staff can enter the interior of the equipment housing 1 through the opening 101, a protective housing 103 is fixedly arranged at the bottom of the interior of the equipment housing 1, a driving motor is fixedly arranged inside the protective housing 103, a duplex table 2 is arranged inside the equipment housing 1, and the output end of the driving motor passes through the top of the protective housing 103 and is fixedly connected to the bottom of the duplex table 2.

The bottom of the arc plate 21 is cooperatively arranged inside the annular groove 102. When the output end of the driving motor drives the double-station platform 2 and the two arc plates 21 to rotate as a whole, the bottom of the arc plate 21 slides inside the annular groove 102. The two arc plates 21 are used to support the double-station platform 2, so that the double-station platform 2 is more stable during rotation.

[0026] Two movable disks 23 are symmetrically arranged on the top of the double-station table 2, and the positions of the two movable disks 23 can be switched with each other. Two servo motors 22 are symmetrically fixedly arranged on the bottom of the double-station table 2. The output end of the servo motor 22 runs through the double-station table 2 and is fixedly connected to the corresponding movable disk 23, and the movable disk 23 is coaxially arranged with the output end of the servo motor 22. A plurality of clamping assemblies 8 and a plurality of workpieces 10 are arranged in a ring shape on the top of the movable disk 23, and the clamping assemblies 8 and the workpieces 10 are arranged one by one. The plurality of clamping assemblies 8 can work simultaneously to clamp the corresponding workpieces 10, and there is no need for the operator to manually clamp and fix all the workpieces 10 in sequence; clamping The component 8 includes two symmetrically arranged fixed plates, the bottom of the fixed plate is fixedly connected to the top of the movable disk 23, a double-headed screw 81 is rotatably connected between the two fixed plates, the outer ends of the double-headed screw 81 are provided with threads of opposite rotation directions, the outer sides of the double-headed screw 81 are symmetrically threadedly connected to two elastic clamping plates 82, the two elastic clamping plates 82 can move away from or approach each other, the bottom of the elastic clamping plate 82 is in sliding contact with the top of the movable disk 23, and a positioning member 9 is fixedly arranged between the two elastic clamping plates 82 in the same clamping component 8, the bottom of the positioning member 9 is fixedly connected to the top of the movable disk 23, and the positioning member 9 can position the workpiece 10 in the clamping area.

[0027] All workpieces 10 are placed on corresponding positioning members 9 respectively. Positioning members 9 position workpieces 10 in clamping areas. During processing or handling, workpieces 10 may be affected by various external forces, such as vibration, impact, etc. Positioning members 9 are fixedly connected to movable disk 23, which can prevent workpieces 10 from being offset or misaligned under external forces, and limit the movement range of workpieces 10 during clamping, thereby improving the accuracy and reliability of clamping; when all double-headed screws 81 rotate at the same time, two elastic clamping plates 82 in the same clamping assembly 8 move close to each other, and the two elastic clamping plates 82 cooperate with each other to clamp and fix the workpiece 10.

[0028] The top of the movable disk 23 is annularly fixedly connected with a plurality of limit strips 231, and the limit strips 231 are arranged one by one with the clamping assembly 8. The two elastic clamping plates 82 in the same clamping assembly 8 slide and cooperate with the corresponding limit strips 231 to realize the linear movement of the elastic clamping plate 82. The bottom of the elastic clamping plate 82 is provided with a notch 821 for the limit strips 231 to pass through; the positioning member 9 is composed of a lower column and an upper column. The lower column is coaxially arranged with the upper column, and the upper column is fixedly connected to the middle of the top of the lower column. The lower column is fixedly connected to the movable disk 23 The diameter of the upper cylinder is smaller than that of the lower cylinder. The workpiece 10 is composed of a plurality of blades, and a collective cylinder is fixedly connected between the plurality of blades. A through circular opening is provided in the middle of the collective cylinder. The diameter of the upper cylinder is the same as the diameter of the circular opening of the collective cylinder of the workpiece 10. The upper cylinder of the positioning member 9 is passed through the circular opening of the collective cylinder of the workpiece 10, so that the workpiece 10 is sleeved on the outside of the positioning member 9, and the bottom of the collective cylinder of the workpiece 10 contacts the top of the lower cylinder of the positioning member 9, and the lower cylinder of the positioning member 9 supports the workpiece 10.

[0029] A guide rod 83 is fixedly connected to the side of one of the elastic clamping plates 82 in the same clamping assembly 8, and the end of the guide rod 83 away from this elastic clamping plate 82 slides linearly through the other elastic clamping plate 82, and a spring 84 is sleeved on the outer side of the guide rod 83, and the two ends of the spring 84 are respectively fixedly connected to the corresponding two elastic clamping plates 82. Due to the existence of the guide rod 83, the deformation of the spring 84 is limited to the axial direction of the guide rod 83, preventing the spring 84 from twisting or bending when subjected to non-axial force; when the two elastic clamping plates 82 approach each other, the spring 84 between them will be compressed. The elastic characteristics of the spring 84 enable it to store energy when compressed and gradually return to its original state when the external force is released. In the process of clamping the workpiece 10, the compression process of the spring 84 provides a buffering effect for the elastic clamping plate 82, which can reduce the impact and damage to the workpiece 10 during the clamping process.

[0030] The inspection station refers to the corresponding lower position of the roughness inspection equipment. At the inspection station, the workpiece 10 is fixed and placed under the roughness inspection equipment. The roughness inspection equipment will measure the surface roughness of the workpiece 10, that is, the measurement of tiny geometric shape errors on the surface of the workpiece 10; the non-inspection station refers to the corresponding lower position that is not currently in the roughness inspection equipment. The non-inspection station is mainly used to prepare the next batch of workpieces 10.

[0031] When the workpieces 10 on one of the movable disks 23 rotate to the inspection station, the other movable disk 23 rotates to the roughness non-inspection station. At this time, the other movable disk 23 can perform positioning operations on another batch of workpieces 10. When all the workpieces 10 on one of the movable disks 23 are inspected, the drive motor is started, and the output end of the drive motor drives the double-station table 2 to rotate, so that the two movable disks 23 swap positions and prepare for roughness inspection of another batch of workpieces 10; when the workpieces 10 on one movable disk 23 are being inspected, the other movable disk 23 can immediately start preparing for the positioning operation of the next batch of workpieces 10. Switching the movable disk 23 between the inspection station and the non-inspection station ensures the continuous operation and efficient use of the equipment, avoids unnecessary idleness and waste, and thus realizes a continuous and efficient production process.

[0032] A first transmission assembly 5 is arranged below the double-station table 2, a second transmission assembly 6 is arranged on the top of the movable disk 23, and a belt assembly 7 is arranged between the second transmission assembly 6 and the first transmission assembly 5. When one of the movable disks 23 rotates from a non-detection station to a detection station, the corresponding first transmission assembly 5, second transmission assembly 6, and belt assembly 7 cooperate with each other to clamp all workpieces 10 on the movable disk 23. At the same time, when the other movable disk 23 rotates from the detection station to the non-detection station, the corresponding first transmission assembly 5, second transmission assembly 6, and belt assembly 7 cooperate with each other to release the clamping of all workpieces 10 on the movable disk 23.

[0033] The clamping and unclamping of the workpiece 10 do not require manual intervention, which improves the automation and intelligence level of the production line. The clamping and unclamping work are completed during the rotation of the corresponding movable disk 23, without additional waiting time, which can improve production efficiency.

[0034] The first transmission assembly 5 includes an inner gear ring 51, two gears 52, two lower fixed shafts 53, and two protective sleeves 54. The inner gear ring 51 is fixedly connected to the inner bottom of the equipment housing 1. The two lower fixed shafts 53 are symmetrically rotatably connected on the duplex table 2, and the lower fixed shafts 53 penetrate the duplex table 2. The bottom of the lower fixed shaft 53 is fixedly connected to the corresponding gear 52. The gear 52 is located on the inner side of the inner gear ring 51, and the gear 52 is meshed with the inner gear ring 51. The top of the lower fixed shaft 53 extends to the top of the duplex table 2 and cooperates with the belt assembly 7. An arc groove 531 begins to be formed at the top of the lower fixed shaft 53. Two protective sleeves 54 are symmetrically fixedly connected to the bottom of the duplex table 2, and the lower fixed shaft 53 penetrates the corresponding protective sleeve 54. The lower fixed shaft 53 can rotate inside the corresponding protective sleeve 54.

[0035] When the output end of the driving motor drives the double-station table 2 and the two movable disks 23 to rotate as a whole, one of the movable disks 23 drives the workpiece 10 thereon to rotate to the detection station. During the process, the gear 52 corresponding to the movable disk 23 engages with the inner gear ring 51 during the revolution, thereby rotating. The gear 52 drives the corresponding lower fixed shaft 53 to rotate in the corresponding protective sleeve 54. The lower fixed shaft 53 can transmit power to the second transmission assembly 6 through the belt assembly 7.

[0036] The second transmission assembly 6 includes a driving gear 61 rotatably connected to the middle of the top of the movable disk 23, a plurality of driven fixed shafts 62 are rotatably connected to the top of the movable disk 23 in an annular shape, a driven gear 63 is fixedly sleeved on the outer side of the driven fixed shaft 62 and close to the lower end, the driven gear 63 is meshed with the driving gear 61, a driven bevel gear 64 is fixedly connected to the top of the driven fixed shaft 62, a transmission bevel gear 65 is fixedly sleeved on the outer side of the double-headed screw 81, and the driven bevel gear 64 is meshed with the corresponding transmission bevel gear 65; The belt assembly 7 includes a driven pulley 71 fixedly connected to the top middle part of the driving gear 61, an upper fixed shaft 74 is rotatably connected to the movable disk 23, the top of the upper fixed shaft 74 passes through the movable disk 23 and is fixedly connected to the driving pulley 72, and the bottom of the upper fixed shaft 74 is fixedly connected to an arc-shaped protrusion 741, the arc-shaped protrusion 741 is adapted to the arc-shaped groove 531, and the arc-shaped protrusion 741 can be cooperatively arranged on the inner side of the arc-shaped groove 531, and a belt 73 is transmission-connected between the driven pulley 71 and the driving pulley 72.

[0037] When one of the movable disks 23 rotates from the non-detection station to the detection station, the arc-shaped protrusion 741 is located inside the arc-shaped groove 531, and the lower fixed shaft 53 rotates by itself, driving the upper fixed shaft 74 to rotate, and the upper fixed shaft 74 drives the driving pulley 72 to rotate, and the driving pulley 72 drives the driven pulley 71 to rotate through the belt 73, and the driven pulley 71 drives the driving gear 61 to rotate, and the rotation of the driving gear 61 can drive multiple driven gears 63 meshing therewith to rotate at the same time, and the driven gear 63 drives the corresponding driven fixed shaft 62 and the driven bevel gear 64 to rotate, and the driven bevel gear 64 drives the corresponding transmission bevel gear 65 to rotate, and the transmission bevel gear 65 drives The corresponding double-headed screw 81 is driven to rotate, so that the two elastic clamping plates 82 on the double-headed screw 81 can approach each other to realize the clamping operation on the workpiece 10; at the same time, the other movable disk 23 is rotated from the detection work station to the non-detection work station. According to the above method, all the double-headed screws 81 on the other movable disk 23 can rotate simultaneously through the corresponding first transmission assembly 5, the second transmission assembly 6, and the belt assembly 7 (the double-headed screw 81 on this movable disk 23 has an opposite thread rotation direction to the double-headed screw 81 on the above-mentioned movable disk 23), so that the two elastic clamping plates 82 on the corresponding double-headed screw 81 move away from each other, thereby releasing the clamping effect on the workpiece 10.

[0038] An electric push rod 3 is symmetrically fixed on the inner bottom of the equipment housing 1, and the telescopic end of the electric push rod 3 is arranged toward the arc plate 21. A socket for plugging the telescopic end of the electric push rod 3 is opened on the arc plate 21, and the socket is adapted to the telescopic end of the electric push rod 3. Before it is necessary to start the drive motor to rotate one of the movable disks 23 from the non-detection station to the detection station, the electric push rod 3 is started in advance, the telescopic end of the electric push rod 3 is shortened, and the telescopic end of the electric push rod 3 is disengaged from the corresponding socket, so that the arc plate 21 will not be obstructed. After one of the movable disks 23 is rotated from the non-detection station to the detection station, the electric push rod 3 is started again, the telescopic end of the electric push rod 3 is extended, and the telescopic end of the electric push rod 3 is inserted into the corresponding socket, so that the arc plate 21 is fixed, thereby ensuring the stability of the workpiece 10 on the movable disk 23 during the detection process.

[0039] A roughness detection assembly 4 is provided at the top of the interior of the device housing 1. The roughness detection assembly 4 includes an electric telescopic rod 41 fixedly provided at the top of the interior of the device housing 1. The telescopic end of the electric telescopic rod 41 is fixedly connected to a roughness detector 42. The extension of the telescopic end of the electric telescopic rod 41 can drive the probe of the roughness detector 42 to contact one of the workpieces 10 to perform a roughness detection on it. This detection technology is a prior art. When one of the workpieces 10 is detected, the corresponding servo motor 22 is started, and the servo motor 22 drives the corresponding movable disk 23 to rotate, and the movable disk 23 drives the upper fixed shaft 74 and the arc-shaped protrusion at the bottom thereof. Part 741 rotates as a whole, and the arc-shaped protrusion 741 disengages from the corresponding arc-shaped groove 531 until the next workpiece 10 rotates to the corresponding lower position of the roughness detection component 4. In this way, the remaining workpieces 10 on the same movable disk 23 can be detected; when the belt assembly 7 rotates to the initial position, it indicates that the movable disk 23 has completed a complete rotation cycle. During this rotation cycle, each workpiece 10 on the movable disk 23 has been brought to the detection position and has undergone roughness detection. The rotation of the belt assembly 7 to the initial position can be used as a sign to determine that all workpieces 10 on the movable disk 23 have been detected.

[0040] By rotating the belt assembly 7 to the initial position as a sign of completion of the inspection, it can be ensured that each workpiece 10 has undergone the necessary inspection steps without omission. If the belt assembly 7 fails to rotate to the initial position on time, it may mean that the equipment has failed or a workpiece 10 has not been properly inspected, and the operator can perform inspections and repairs.

[0041] It should be noted that: when the output end of the driving motor drives the double-station table 2 and the two movable disks 23 to rotate as a whole, one of the movable disks 23 rotates from the non-detection station to the detection station, and the other movable disk 23 rotates to the non-detection station. When the two movable disks 23 need to be switched, the rotation direction of the output end of the driving motor needs to be changed. When one of the movable disks 23 is being detected at the detection station, the other movable disk 23 has been unloading the detected workpiece 10 at the non-detection station and preparing for the positioning of the new workpiece 10.

[0042] The detection method of aircraft engine blade processing includes the following steps: S1, the double-station table 2 and the two movable disks 23 can rotate as a whole, the workpiece 10 on one movable disk 23 rotates to the inspection station, and the other movable disk 23 rotates to the non-inspection station; S2. When one of the movable disks 23 rotates from the non-detection station to the detection station, the corresponding first transmission assembly 5, the second transmission assembly 6, and the belt assembly 7 cooperate with each other to clamp all the workpieces 10 on the movable disk 23; at the same time, the workpiece 10 on the other movable disk 23 is released from the clamp, ready for unloading and positioning of the new workpiece 10; S3, when the workpiece 10 on one of the movable disks 23 rotates to the detection station, the roughness detection can be performed; S4. After all the workpieces 10 on one of the movable disks 23 have been inspected, the two movable disks 23 are swapped. The movable disk 23 originally at the inspection station is rotated to the non-inspection station to unload and prepare for positioning of new workpieces 10, while the movable disk 23 originally at the non-inspection station is rotated to the inspection station to carry out roughness inspection of the next batch of workpieces 10.
