Description

Technical Field

[0001] This invention belongs to the field of parts inspection technology and relates to a multifunctional composite parts inspection tool. Background Technology

[0002] In industries such as machinery manufacturing, automotive, rail transportation, consumer electronics, and aerospace, the geometry and dimensional accuracy of components directly affect the assembly quality, functional performance, and service safety of the entire machine. Currently, a large number of structural parts are mass-produced through processes such as stamping, welding, casting, or sheet metal forming. However, during actual processing, factors such as fluctuations in raw materials, mold wear, changes in equipment condition, and unstable process parameters often lead to defects in the formed parts, such as dimensional deviations, contour deformation, hole misalignment, and insufficient flatness. If these defects are not detected in time, they can cause assembly difficulties, increased rework rates, and even product failure. Therefore, it is essential to strictly inspect critical dimensions and geometric features.

[0003] Traditional inspection methods rely heavily on human experience, with quality inspectors making judgments through visual comparison or using general measuring tools such as calipers, micrometers, and plug gauges. While this method is low-cost, it suffers from high subjectivity, poor repeatability, and low efficiency, especially in meeting the high-precision inspection requirements of micrometer-level or complex curved surfaces. To improve inspection consistency, the industry has gradually introduced specialized inspection tools, such as customized gauges, profiling templates, and go / no-go gauge combinations, to assist manual judgment of specific dimensional items. These tools have improved the standardization and efficiency of inspection to some extent, but they still rely heavily on manual operation—from clamping and measurement to result interpretation, all require human intervention. This not only results in a slow inspection cycle and high labor intensity, but also increases the risk of missed inspections or misjudgments due to fatigue during long hours of work. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional composite component inspection tool that can automatically and quickly inspect the dimensions of components in multiple aspects, replacing manual labor. It has higher inspection accuracy and efficiency, in order to meet the higher requirements of modern intelligent manufacturing for quality consistency, traceability and automation.

[0031] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed explanation of the multifunctional composite component testing tool proposed in this invention. The advantages and features of this invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this invention. The same or similar reference numerals in the drawings represent the same or similar components.

[0032] Example, refer to Figure 1-10A multifunctional composite component inspection tool includes a frame 1. A positioning plate 2 is located at the bottom of the frame 1. Multiple upward-facing fixed columns 3 are mounted on the upper end of the positioning plate 2. A negative pressure suction head 4 is located on one side of each fixed column 3. A negative pressure suction cup 5 is located at the upper end of each negative pressure suction head 4. A negative pressure connecting pipe 6, connected to the negative pressure suction cup 5, is located at the lower end of each negative pressure suction head 4. The negative pressure connecting pipe 6 is used to connect to a negative pressure pump. When a component is placed on the negative pressure suction head 4, the negative pressure pump generates negative pressure on the negative pressure suction cup 5, thus suctioning and fixing the component. Multiple positioning blocks 7 are mounted on the upper end of the positioning plate 2. An L-shaped positioning plate 8 is positioned upward-facing on the upper end of each positioning block 7. At least two diagonally opposite positioning blocks 7 are required for each component positioning, allowing the two L-shaped positioning plates 8 to position the two diagonals of the component, facilitating quick placement of the component into the designated position. The upper end of the positioning plate 2 is equipped with multiple upward-facing support columns 9. Each support column 9 has a support head 10 on one side. A movable through hole 11 is opened through each support head 10 downward. The movable through hole 11 corresponds to the opening on the component, which facilitates the insertion of the detection shaft into the opening for detection. At the same time, the support head 10 provides support to prevent the component from bending and deforming when the detection shaft is inserted into the opening.

[0033] The positioning plate 2 has multiple downwardly arranged mounting holes 12, each with an internal thread. Each fixed column 3, each supporting column 9, and each positioning block 7 has a downwardly arranged pressing hole 13 at its upper end. Each pressing hole 13 has a downwardly arranged connecting through hole 14 at its bottom, which passes through the corresponding fixed column 3, supporting column 9, or positioning block 7. The inner diameter of each connecting through hole 14 is smaller than the inner diameter of the pressing hole 13. The plate also includes a connecting bolt 15 that mates with the connecting through hole 14 and can be threaded into the mounting hole 12. Each connecting bolt 15 has a nut 16 at its upper end that mates with the pressing hole 13. Each nut 16 has a downwardly arranged internal hexagon socket 17 at its upper end. By using the connecting bolt 15, the fixed column 3, supporting column 9, and positioning block 7 can be removed and adjusted to any position, allowing for flexible adjustment according to the shape of the components.

[0034] A lifting frame 18 is movably mounted above the positioning plate 2 within the frame 1. Two hydraulic telescopic cylinders 19 are vertically mounted on the upper end of the frame 1. The lower end of the telescopic shaft of each hydraulic telescopic cylinder 19 is connected to the lifting frame 18. A detection plate parallel to the positioning plate 2 is movably mounted on the lower side of the lifting frame 18. The hydraulic telescopic cylinders 19 are used to drive the detection plate to move up and down. A slide rail 20 is provided on both sides of the lower end of the lifting frame 18 along its length. A slide bar 21 is provided on both sides of the detection plate and is slidably connected to the corresponding slide rail 20. Each slide bar 21 has a rack 22 arranged along its length on its outer side. The bottom of each slide rail 20 is recessed inward to form a strip-shaped movable groove 23 that engages with the corresponding rack 22. A drive motor 24 is installed at one end of each slide rail 20. Each drive motor 24 is connected to a drive gear 25 that extends into the corresponding strip-shaped movable groove 23 and meshes with the corresponding rack 22. When the drive motor 24 is working, it can drive the rack 22 to move through the drive gear 25, thereby driving the detection plate to move left and right.

[0035] The detection plate is divided into a first detection area 26, a second detection area 27, and a third detection area 28 distributed along its length. The first detection area 26 matches the shape of the positioning plate 2. The first detection area 26 has multiple upper mounting holes 29, which correspond one-to-one with the lower mounting holes 12. Each upper mounting hole 29 has an internal thread. The lower end of the first detection area 26 is equipped with multiple insertion hole detection units that cooperate with the support head 10. The lower end of the second detection area 27 is horizontally provided with a first linear motor 30. The first linear motor 30 is provided with two moving parts, and each moving part is provided with an edge detection unit downward. The lower end of the third detection area 28 is horizontally provided with a second linear motor 31. The second linear motor 31 is provided with two moving parts, and each moving part is provided with an end face detection unit downward.

[0036] The socket detection unit includes a connector 32 connected to the first detection area 26. The upper end of the connector 32 has an upward-facing threaded connecting shaft 33 that can be threadedly connected to the upper mounting hole 29. The upper end of the threaded connecting shaft 33 has an upward-facing power connector 34 that is electrically connected to the first air pressure sensor 39, allowing the socket detection unit to be detached and its position to be adjusted arbitrarily according to the location of the component openings. A first sealing tube 35 is downward-facing from the connector 32. The lower end of the first sealing tube 35 has a first piston hole (not shown). A first sealing piston 36 is slidably connected inside the first sealing tube 35, which is sealed with air. The air inside the first sealing tube 35 tends to push the first sealing piston 36 downwards. A detection coarse shaft 37 is slidably connected to the first piston hole from the first sealing piston 36. A detection fine shaft 38 with a smaller outer diameter is downward-facing from the lower end of the detection coarse shaft 37. A first air pressure sensor 39 for detecting the internal air pressure is located at the upper part of the first sealing tube 35. When inspecting the opening of a component, the hydraulic telescopic cylinder 19 drives the inspection plate to descend, so that the inspection thin shaft 38 is first inserted into the opening of the component, and then the inspection thick shaft 37 is inserted into the opening of the component. The first air pressure sensor 39 detects the change in air pressure in the first sealing tube 35 to determine whether the inspection thin shaft 38 or the inspection thick shaft 37 is inserted into the opening of the component. If only the inspection thick shaft 37 can be inserted, the opening is qualified. If the inspection thick shaft 37 cannot be inserted or the inspection thin shaft 38 can be inserted, the opening is unqualified.

[0037] The edge detection unit includes a torque sensor 40 mounted below the mover of the first linear motor 30. An edge detection pin 41 is positioned downwards at the lower end of the torque sensor 40. The torque sensor 40 detects whether the edge detection pin 41 is bent. After the edge detection pin 41 is moved to the edge of the component by the drive motor 24, it is then moved to the front and rear sides of the component by the first linear motor 30. When the drive motor 24 moves the detection plate, it causes the edge detection pin 41 to move on the front and rear sides of the component. When detecting the left and right sides of the component, the drive motor 24 first moves the edge detection pin 41 to one side of the component, and then the first linear motor 30 moves the edge detection pin 41 on the left and right sides of the component. Through the contact between the edge detection pin 41 and the edge of the component, the torque sensor 40 senses the bending change of the edge detection pin 41 in real time, and uses this change to determine whether the edge dimensions of the component are acceptable.

[0038] The end face detection unit includes a telescopic motor 42 disposed downward below the mover of the first linear motor 30. The lower end of the telescopic shaft of each telescopic motor 42 is connected to a downwardly disposed second sealing tube 43. The lower end of the second sealing tube 43 is provided with a second piston hole (not shown). A second sealing piston 44 is slidably connected inside the second sealing tube 43. Air is sealed inside the second sealing tube 43. The air inside the second sealing tube 43 has a tendency to push the second sealing piston 44 downward. A second air pressure sensor 45 for detecting the internal air pressure is disposed on the upper part of the second sealing tube 43. A telescopic contact shaft 46 is disposed downward on the second sealing piston 44 and slidably connected to the second piston hole. A ball head groove 47 is provided at the lower end of the telescopic contact shaft 46. A rolling ball head 48 is rotatably connected inside the ball head groove 47. When it is necessary to check whether the surface of a component is qualified, the telescopic motor 42 first extends to drive the telescopic contact shaft 46 to extend downward, making it lower than the edge detection needle 41 to prevent damage when the device descends. At the same time, the hydraulic telescopic cylinder 19 extends to drive the telescopic contact shaft 46 downward to contact the surface of the component. The drive motor 24 drives the telescopic contact shaft 46 to move laterally, and the second linear motor 31 drives the telescopic contact shaft 46 to move longitudinally, so that the telescopic contact shaft 46 can move arbitrarily on the surface of the component, so that the rolling ball head 48 rolls on the surface of the component. If a part of the component is tilted upward or bent downward, the air pressure in the second sealing tube 43 will change. This air pressure change is detected by the second air pressure sensor 45 to determine whether the surface of the component is qualified.

[0039] Working principle: Based on the shape and opening position of the parts, adjust the positions of the fixed column 3, the support column 9, and the positioning block 7 to ensure that the support head 10 corresponds to the opening of the parts. At the same time, use the L-shaped positioning plate 8 to initially position the parts. Place the parts to be inspected on the positioning plate 2, and use the negative pressure generated by the negative pressure suction cup 5 to firmly fix them, so that the support head 10 is supported at the opening position of the parts.

[0040] The hydraulic telescopic cylinder 19 is activated, driving the detection plate to descend, causing the detection fine shaft 38 and detection coarse shaft 37 of the insertion hole detection unit to be inserted into the opening of the component in sequence. The first air pressure sensor 39 detects the air pressure change in the first sealing tube 35 to determine whether the opening is qualified. If only the detection coarse shaft 37 can be inserted, the opening is qualified; if the detection coarse shaft 37 cannot be inserted or the detection fine shaft 38 cannot be inserted, the opening is unqualified.

[0041] The drive motor 24 operates, driving the detection plate to move left and right through the cooperation of the drive gear 25 and rack 22, causing the edge detection needle 41 of the edge detection unit to move to the edge position of the component. The first linear motor 30 drives the edge detection needle 41 to move in front of, behind, left or right of the component, and the torque sensor 40 senses the bending change of the edge detection needle 41 in real time to determine whether the edge dimension of the component is qualified.

[0042] When the surface of a component needs to be inspected, the telescopic motor 42 extends, driving the telescopic contact shaft 46 to extend downwards and contact the surface of the component. The drive motor 24 and the second linear motor 31 drive the telescopic contact shaft 46 to move laterally and longitudinally, respectively, causing the rolling ball head 48 to roll on the surface of the component. If the surface of the component is warped or bent, it will cause a change in the air pressure inside the second sealing tube 43. This change in air pressure is detected by the first air pressure sensor 39, which can then be used to determine whether the surface of the component is qualified.

[0043] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
