Description

Technical Field

[0001] The present invention relates to the technical field of equipment parts detection, and more specifically, to a sealing ring visual detection device. Background Art

[0002] The sealing ring, also known as the sealing ring, is a precision component used in aircraft engines. Its main function is to maintain the air tightness or oil tightness of the system under high pressure and high temperature environment to ensure the normal operation of the engine. Due to the extremely harsh working environment of the aircraft engine, the sealing ring must have extremely high dimensional accuracy, especially the inner and outer diameter accuracy, as well as surface quality, which is not only to ensure its sealing performance, but also to reduce wear and increase service life.

[0003] The manufacturing of sealing rings usually requires high-precision processing technology, and its quality control relies on strict testing standards. The traditional testing method mainly uses go gauges and no-go gauges, which is a method of physically checking whether the workpiece meets the size specifications. The go gauge is used to check the maximum limit size of the hole, and the no-go gauge is used to check the minimum limit size of the hole. This testing method is very slow and cannot measure accurate data. Moreover, one go gauge and one no-go gauge can only correspond to one product, and cannot detect products of multiple specifications, which requires high testing and production costs.

[0033] Among them, the equipment of the present invention adopts the cone body 3-9 rotating assembly to place products, and can place products of various specifications, and detect the inner and outer diameters of the sealing ring through the high-precision visual inspection assembly 4, put the sealing ring on the cone body 3-9, and then the cone rotating body assembly 3 rotates slowly, and at the same time the Z-axis motion assembly 5 adjusts the position of the circle calibration assembly 2, and adapts to the sealing rings of different sizes and shapes by adjusting the circle calibration assembly 2. After the circle calibration assembly 2 clamps and fixes the sealing ring, the visual inspection assembly 4 automatically positions and focuses to measure the size data of the sealing ring at multiple points, so as to detect products of different specifications. Through the precise positioning of the circle calibration assembly 2 and the Z-axis motion assembly 5, and the positioning and focusing detection of the visual inspection assembly 4, the equipment can accurately detect the inner and outer diameters of the sealing rings of various specifications placed in the cone rotating body assembly 3. Compared with the prior art, the technical solution involved in the present invention can accurately detect products of various specifications, with lower detection and production costs, shorter detection time, and higher efficiency.

[0034] Specifically, Figure 2 In an embodiment of the present invention, the circle calibration component 2 also includes: a circle calibration mounting plate 2-1 arranged on the Z-axis motion component 5; and adjustment components 2-2 evenly distributed on the circle calibration mounting plate 2-1, wherein the adjustment components 2-2 are used to fix the position of the sealing ring.

[0035] Among them, the calibration component 2 can set the sealing ring at a predetermined position to ensure that the position of the sealing ring is consistent each time it is measured, and more accurately control the placement of the sealing ring, thereby reducing the measurement error caused by position changes and measurement errors caused by inconsistent postures. In actual production, it is necessary to measure the sealing rings in batches. The stable platform provided by the calibration component 2 ensures that the sealing ring is in the same position each time it is measured, and the results of each measurement are repeatable, which is convenient for manufacturers to test the consistency of batch products.

[0036] Specifically, the number of the adjustment components 2-2 is 4 to 8.

[0037] Among them, more preferably, the number of adjustment components 2-2 is specifically 6.

[0038] Among them, the circle calibration component 2 provides a stable measurement platform in visual inspection.

[0039] Specifically, Figure 3In the embodiment of the present invention, the adjustment component 2-2 includes: an adjustment servo motor seat 2-2-2 arranged on the frame 1; an adjustment servo motor 2-2-1 arranged on the adjustment servo motor seat 2-2-2; an adjustment coupling 2-2-3 connected to the output shaft of the adjustment servo motor 2-2-1; an adjustment screw 2-2-6 whose input end is connected to the adjustment coupling 2-2-3; an adjustment screw fixed to the end of the adjustment screw 2-2-6 close to the servo motor seat 2-2-2 End 2-2-4; an adjusting screw support end 2-2-9 arranged at the end of the adjusting screw 2-2-6 away from the servo motor seat 2-2-2; an adjusting screw nut connecting seat 2-2-7 arranged on the screw nut of the adjusting screw 2-2-6; adjusting pads 2-2-5 arranged at both ends of the adjusting screw 2-2-6; an adjusting linear guide 2-2-8 arranged on the circle calibration mounting plate 2-1; an adjusting screw connecting seat 2-2-7 arranged on the slider of the adjusting linear guide 2-2-8.

[0040] The adjustment component 2-2 can adapt to sealing rings of different sizes and shapes, and ensure that each type of sealing ring can be correctly fixed by adjusting the position. In addition, by adjusting the component 2-2, the placement of the sealing ring can be accurately controlled, and the slight error of the sealing ring during the setting process can be compensated, thereby ensuring the accuracy of the test results.

[0041] Among them, when the servo motor is running, it will drive the adjusting screw 2-2-6 to rotate through the adjusting coupling; the two ends of the adjusting screw 2-2-6 are supported by the adjusting screw fixed end 2-2-4 and the adjusting screw support end 2-2-9 to ensure the stable rotation of the screw; the rotation of the adjusting screw 2-2-6 will cause the screw nut installed on it to move up and down, thereby driving the adjusting screw nut connecting seat 2-2-7 connected to it to move; the adjusting screw nut connecting seat 2-2-7 is installed on the slider of the adjusting linear guide 2-2-8, so that the adjusting screw nut connecting seat 2-2-7 moves along the linear guide 2-2-8, ensuring the accuracy of position adjustment. In addition, the adjusting pads 2-2-5 are set at both ends of the adjusting screw 2-2-6 to ensure the correct alignment and stability of the screw. To sum up, the adjusting servo motor 2-2-1 can drive the adjusting pressure block 2-2-10 to move back and forth along the direction of the adjusting linear guide rail 2-2-8, so that the adjusting component 2-2 can more accurately make adaptive adjustments to sealing rings of different sizes, thereby accurately fixing the sealing ring and ensuring that the sealing ring will not move, deform or tilt during the detection process.

[0042] Specifically, Figure 4 In an embodiment of the present invention, the conical rotating body assembly 3 further includes: a vertical rotating mechanism for driving the conical body 3-9 to rotate, and the conical body 3-9 is arranged on the vertical rotating mechanism.

[0043] Specifically, Figure 4 and Figure 5 In an embodiment of the present invention, the vertical rotation mechanism includes: a rotating servo motor seat 3-2 arranged on the frame 1; a rotating bearing seat 3-5 arranged on the frame 1; a rotating servo motor and a right-angle reducer 3-1 arranged on the rotating servo motor seat 3-5; a rotating coupling 3-3 connected to the output shaft of the rotating servo motor and the right-angle reducer 3-1; a rotating main shaft 3-4 connected to the rotating coupling 3-3; a rolling bearing 3-6 arranged in the blind holes at the upper and lower ends of the rotating bearing seat 3-5; and a limiting ring 3-7 for limiting and fixing the rolling bearing 3-6.

[0045] Among them, the conical rotating body assembly 3 makes the sealing ring rotate evenly during the measurement process, providing detection opportunities from multiple viewing angles, thereby obtaining all-round image data, which is convenient for all-round detection of its geometric features, such as roundness, radial runout, size, etc. By rotating, it can be ensured that the detection system can scan the entire circumference of the sealing ring, thereby detecting its roundness and any local deformation; by rotating, data can be collected from multiple angles and then compared and analyzed. The data from multiple angles can be used for statistical analysis, such as calculating the mean value, standard deviation, etc., so as to more accurately evaluate the quality of the sealing ring.

[0046] Specifically, Figure 6 In an embodiment of the present invention, the visual inspection component 4 includes: an X-axis linear guide 4-8 arranged on the crossbeam of the frame 1; an X-axis movable plate 4-9 arranged on the slider of the X-axis linear guide 4-8, and the X-axis linear guide 4-8 is used to move the X-axis movable plate 4-9 laterally; a Y-axis linear guide 4-20 arranged on the X-axis movable plate 4-9; a manual fine-tuning platform mounting plate 4-17 connected to the slider on the Y-axis linear guide 4-20, and the Y-axis linear guide 4-20 is used to radially move the manual fine-tuning platform mounting plate 4-17; a manual fine-tuning platform 4-18 arranged on the manual fine-tuning platform mounting plate 4-17; a measuring instrument mounting plate 4-19 arranged on the setting surface of the manual fine-tuning platform 4-18; and a visual inspection instrument 4-21 arranged on the measuring instrument mounting plate 4-19.

[0047] Among them, the visual inspection component 4 can move in two directions to inspect different positions of the sealing ring, covering a larger inspection area than a single-line movement, and can obtain multi-point measurement data, which is convenient for inspecting large or complex sealing rings. At the same time, multi-angle image acquisition data improves data integrity. In addition, by adjusting the movement range according to different specifications, it can adapt to products of different sizes, and can complete multiple inspection tasks on the same inspection platform, thereby improving the utilization rate of the equipment.

[0048] Specifically, Figure 6 In the embodiment of the present invention, the visual detection component 4 also includes: an X-axis servo motor seat 4-2 arranged on the frame 1; an X-axis servo motor 4-1 arranged on the X-axis servo motor seat 4-2; an X-axis coupling 4-3 connected to the output shaft of the X-axis servo motor 4-1; an X-axis screw rod 4-5 whose input end is connected to the X-axis coupling 4-3; an X-axis screw rod fixed end 4-4 arranged at one end of the X-axis screw rod 4-5 close to the X-axis servo motor seat 4-2; an X-axis screw rod supporting end 4-7 arranged at one end of the X-axis screw rod 4-5 away from the X-axis servo motor seat 4-2; an X-axis screw rod nut connecting seat 4-6 arranged on the screw rod nut of the X-axis screw rod 4-5, the X-axis screw rod nut connecting seat 4-6 The socket 4-6 is connected to the X-axis moving plate 4-9; a servo motor seat 4-10 is arranged on the X-axis moving plate 4-9; a servo motor 4-11 is arranged on the servo motor seat 4-10; a coupling 4-12 is connected to the output shaft of the servo motor 4-11; a screw rod 4-15 whose input end is connected to the coupling 4-12, and the screw nut of the screw rod 4-15 is connected to the manual fine-tuning platform mounting plate 4-17; a screw rod fixed end 4-13 is arranged at one end of the screw rod 4-15 close to the servo motor seat 4-10; a screw rod supporting end 4-16 is arranged at the end of the screw rod 4-15 away from the servo motor seat 4-10; and pads 4-14 are arranged at both ends of the screw rod 4-15.

[0049] Among them, through the dual-guide movement driven by the motor 4-1, the visual inspection instrument 4-21 can inspect the sealing ring with a multi-layer structure at different levels. At the same time, by adjusting the moving position and manually fine-tuning the platform 4-18, it is ensured that the visual inspection instrument is in the best focal position to avoid obstacles that may block the detection field of view, ensure unobstructed image acquisition, and obtain the clearest image.

[0050] Specifically, Figure 7In the embodiment of the present invention, the Z-axis motion assembly 5 includes: a Z-axis support column 5-1 arranged on the frame 1; a Z-axis servo motor seat 5-3 arranged on the Z-axis support column 5-1; a Z-axis servo motor 5-2 arranged on the Z-axis servo motor seat 5-3; a Z-axis coupling 5-4 connected to the output shaft of the Z-axis servo motor 5-2; a Z-axis screw rod 5-6 connected to the input end of the Z-axis coupling 5-4; a Z-axis screw rod 5-6 arranged near the Z-axis servo motor seat 5-3 A Z-axis screw fixed end 5-5 at one end; a Z-axis screw support end 5-8 arranged at one end of the Z-axis screw 5-6 away from the Z-axis servo motor seat 5-3; a Z-axis screw nut connecting seat 5-7 arranged on the screw nut of the Z-axis screw 5-6; a Z-axis linear guide 5-9 arranged on the Z-axis support column 5-1; a Z-axis movable mounting plate 5-10 arranged on the slider of the Z-axis linear guide 5-9, and the Z-axis movable mounting plate 5-10 is connected to the Z-axis screw nut connecting seat 5-7.

[0051] Among them, through the movement of the Z-axis, the sealing rings of the multi-layer structure can be inspected layer by layer, and at the same time, it can adapt to sealing rings of different thicknesses or heights, ensuring the versatility and adaptability of the detection system, thereby improving the versatility of the system and being compatible with various types of sealing rings. There is no need to frequently replace the detection equipment, thereby reducing the cost of detection and production and improving detection efficiency.

[0052] To be more specific, the sealing ring, as a thin-walled circular ring part, plays a vital role in the engine, so there are extremely strict requirements for the accuracy of its inner diameter and outer diameter. The existing detection methods mainly rely on the method of go gauge plus no-go gauge, which leads to high detection production costs, long detection time and low efficiency. In addition, since each specification of product requires a special go gauge and no-go gauge, it is difficult to adapt to the detection of multiple specifications of products. At the same time, it is impossible to read the specific product detection data, and can only judge whether it is qualified. The lack of accurate data support is not conducive to quality control and technical improvement.

[0053] Based on the existing technical problems, the embodiment of the present invention adopts a tapered and rotatable conical rotating body assembly for placing products of various specifications; it is equipped with a high-precision visual inspection instrument, and the instrument can be controlled to move in the X-axis and Y-axis directions; a sealing ring calibration component is set to ensure the detection accuracy; and a manual fine-tuning platform is also provided to enable the high-precision visual inspection instrument to be positioned more accurately. The equipment uses the X-axis and Y-axis linkage to drive the high-precision visual inspection instrument to detect the inner and outer diameters of the sealing ring, and uses a tapered conical body to place products of various specifications, thereby achieving efficient, accurate and multifunctional detection effects.
