Description

Technical Field

[0001] This invention relates to the field of workpiece inspection technology, and in particular to a mechanism and device for detecting burrs inside holes of workpieces. Background Technology

[0002] In the inspection of burrs in deep, elongated holes on metal parts, two main methods are currently employed: manual and automated. Manual inspection typically uses a handheld endoscope, but the operator's hand is difficult to keep absolutely stable, especially when pressing the shutter button, which easily causes tremors, resulting in blurred images and affecting inspection accuracy. Automated inspection uses a mechanical mechanism to drive the endoscope in a cyclical process of "movement-sudden stop-photograph-movement" to improve efficiency. However, at the moment of sudden stop, the endoscope may vibrate or swing due to inertia, similarly causing image blurring.

[0003] To address the above problems, existing technologies mainly offer two types of solutions: One method is structural image stabilization, such as the use of magnetically variable materials to adjust the hardness of the microscope tube in patent CN202410117578.9 to suppress shaking. However, without external support, the soft microscope tube is more prone to wobbling during sudden stops, exacerbating blur; and the magnetic material may interfere with internal signal lines, causing image distortion.

[0004] Secondly, there is optical compensation, such as patent CN202411343486.9, which uses sensors to collect motion data and drive optical image stabilization components to perform image compensation. However, existing optical image stabilization systems have insufficient response speed, making it difficult to cope with the instantaneous shaking caused by rapid stops, and the systems are complex, costly, and difficult to maintain.

[0005] Therefore, there is an urgent need for a new type of burr detection mechanism that balances stability, response speed, and practicality to effectively solve the image blurring problem in automatic detection. Summary of the Invention

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0022] The following is combined with Figures 1-8 This invention describes a mechanism and apparatus for detecting burrs inside holes in a workpiece, according to embodiments of the present invention.

[0023] like Figure 1 As shown, this embodiment of the invention provides a mechanism for detecting burrs inside a workpiece hole, comprising: an insertion part 1, a lens module 2, a control part 3, and a stabilization part 4; the insertion part 1 is adapted to be inserted into the hole to be tested in the workpiece; the lens module 2 is disposed at one end of the insertion part 1; the control part 3 is disposed at the end of the insertion part 1 away from the lens module 2 and connected to the lens module 2; the stabilization part 4 is disposed in the insertion part 1 and is disposed close to the lens module 2, and the stabilization part 4 is adapted to cooperate with the hole to be tested.

[0024] It should be understood that, by setting an anti-shake part 4 that cooperates with the inner wall of the hole to be tested at the position of the insertion part 1 near the lens module 2, the embodiment of the present invention effectively suppresses the shaking caused by inertia or vibration of the lens during the "movement-sudden stop-photographing" process, and significantly improves the image clarity and the accuracy of burr recognition. The structure is compact and does not rely on magnetic variable materials or optical image stabilization components, avoiding problems such as electromagnetic interference, response delay and high cost. It has good stability, adaptability and economy, and is suitable for efficient and high-precision detection scenarios in deep and long holes that are automated or semi-automated.

[0025] In some possible implementations, the insertion part 1 is a slender rod-shaped or hollow tubular structure, and its outer diameter is designed to be adapted to the inner diameter of the hole to be measured, so as to ensure that it can be smoothly inserted into the deep hole of the workpiece, while providing the necessary installation space and structural support for the internal functional components; the insertion part 1 may be made of hard metal material.

[0026] Lens module 2 is located at one end near the bottom of the aperture to be tested. Lens module 2 typically includes a miniature optical lens, an image sensor, an illumination unit, and necessary signal conditioning circuitry. The entire lens module 2 adopts a sealed encapsulation structure, providing excellent dustproof, oilproof, and electromagnetic interference resistance.

[0027] The control unit 3 is electrically connected to the lens module 2 via a flexible signal cable built into the insertion unit 1. The control unit 3 receives image data acquired by the lens module 2, sends control commands to the lens module 2, and can further communicate with external image processing systems, motion control platforms, or host computers. In some embodiments, the control unit 3 may also integrate a power management module, a local storage unit, or a wireless communication module to support offline operation or remote control requirements.

[0028] The image stabilization unit 4 is located close to the lens module 2, preferably within a region no more than one-fifth of the total length of the insertion part 1 from the lens module 2. The image stabilization unit 4 is configured to form a stable contact or a slight interference fit with the inner wall of the hole after the insertion part 1 enters the hole to be tested, thereby providing local mechanical support near the lens module 2 and effectively suppressing lens shake caused by movement, sudden stop or external disturbance.

[0029] The image stabilization unit 4 can be made of flexible materials such as sleeves, retractable ball bearing structures, air-filled expansion elements, or shape memory alloy-driven adaptive support structures. Regardless of the specific form used, the design of the image stabilization unit 4 follows the principle of providing immediate and reliable mechanical constraints in key image acquisition areas without scratching or damaging the inner wall of the workpiece, thereby effectively suppressing lens shake and ensuring image clarity.

[0030] like Figure 2 As shown, according to an embodiment of the present invention, a mechanism for detecting burrs inside a workpiece hole is provided. The anti-shake part 4 includes: a mounting part 41 disposed on the surface of the insertion part 1; and a support part, one side of which is disposed on the mounting part 41, and the other side of which is adapted to cooperate with the hole wall of the hole to be tested.

[0031] It should be understood that the mounting component 41 is fixedly disposed on the outer peripheral surface of the insertion part 1, and its structure is adapted to the shape of the insertion part 1. It can be reliably fixed by means of nesting, bonding, threaded connection or integral molding to ensure that no loosening or displacement occurs during the testing process. The support component is configured to have a certain degree of elasticity or flexibility, and can generate controllable deformation when in contact with the hole wall, thereby providing radial support force, forming a stable constraint on the front end of the insertion part 1, and effectively suppressing the shaking of the lens module 2 during movement, sudden stop or vibration.

[0032] In some possible implementations, the connection between the support and the mounting component 41 can be a fixed connection or a detachable connection. In a detachable structure, the support can be replaced according to different aperture specifications, improving the versatility and adaptability of the mechanism. In other embodiments, the support can also integrate a micro-strain sensor to monitor its contact state with the aperture wall in real time, providing feedback for image acquisition timing.

[0033] like Figure 2 and Figure 3 As shown, according to an embodiment of the present invention, a mechanism for detecting burrs inside a workpiece hole is provided. The mounting member 41 is cylindrical and sleeved on the insertion part 1; the support member is a flexible wire 421, and there are multiple flexible wires 421, which are evenly distributed along the circumference of the mounting member 41; one end of the flexible wire 421 is fixedly connected to the surface of the mounting member 41, and the other end of the flexible wire 421 extends away from the mounting member 41, which is suitable for abutting against the hole wall of the hole to be tested; wherein, when the insertion part 1 drives the anti-vibration part 4 to move axially along the hole to be tested, the flexible wire 421 abuts against the hole wall and deforms, thereby generating damping.

[0034] It should be understood that the cylindrical mounting component 41 can be securely connected to the insertion part 1 by means of interference fit, adhesive, snap-fit, or set screw, ensuring that no axial slippage or circumferential rotation occurs during the testing process, thereby providing a reliable installation reference for the support component. There are multiple support components, which are evenly distributed along the circumference of the mounting component 41 to form a symmetrical and balanced support layout in the circumferential direction.

[0035] In some possible implementations, the flexible wire 421 has a radial wire-like structure centered on the mounting member 41, and the diameter of the flexible wire 421 is preferably 0.3mm-1mm. The radial flexible wire 421 forms a uniform radial support force on the insertion part 1, which can keep the lens module 2 always in the axial position of the hole to be tested. This helps to guide the insertion part 1 to be centered during insertion, avoiding deviation to one side of the hole wall and preventing the lens module 2 from rubbing or colliding with the hole wall and causing vibration. Even if the structural scheme is applied to an automatic detection system with low motion accuracy, it can achieve rapid, automatic, and high-precision centering of the endoscope, ensuring that the images acquired each time are at the same shooting angle. After the insertion part 1 is inserted into the deep and long hole, the radial flexible wire 421 fills the gap between the insertion part 1 and the hole wall, forming a flexible damping structure. When the lens moves quickly and stops suddenly, it plays a flexible buffering role, converting the kinetic energy of vibration into elastic potential energy, avoiding lens vibration, and improving the stability of the detection image.

[0036] The flexible wire 421 can be made of polyetheretherketone, thermoplastic polyurethane, medical-grade silicone, or other non-metallic engineering materials with high elastic modulus, low coefficient of friction, and good wear resistance. This flexibility allows the flexible wire 421 to produce controllable elastic deformation when in contact with the hole wall, which can accommodate a certain range of hole diameter tolerances while avoiding scratches or damage to the inner wall of the workpiece. In addition, due to its flexibility, the flexible wire 421 can be backward compatible with smaller hole diameters.

[0037] like Figure 2 As shown, according to an embodiment of the present invention, a mechanism for detecting burrs inside a workpiece hole is provided, wherein the flexible wire 421 comprises multiple layers, and the multiple layers of flexible wires 421 are spaced apart along the axial direction of the mounting member 41; wherein the number of each layer of flexible wires 421 is at least 8.

[0038] It should be understood that the flexible wires 421 are divided into multiple layers along the axial direction of the mounting member 41, with a predetermined axial interval between each layer, forming a multi-level support system distributed along the length of the insertion part 1. Each layer contains no fewer than 8 flexible wires 421, which are evenly distributed circumferentially along the mounting member 41, ensuring sufficient and symmetrical radial constraint force on any cross-section. The multi-layer structure significantly enhances the overall stability and guiding performance of the image stabilization part 4. During the insertion part 1's entry into the deep, elongated hole, the multiple layers of flexible wires 421 work synergistically, effectively limiting not only the radial sway of the front end of the lens module 2 but also suppressing torsional or bending vibrations of the insertion part 1 within the hole, making it particularly suitable for hole inspection scenarios with high depth-to-diameter ratios. Simultaneously, since each layer contains no fewer than 8 flexible wires 421 (preferably 12-20), they form dense support points in the circumferential direction, allowing for more precise adaptation to minute geometric deviations of the hole's inner wall, improving the mechanism's self-centering capability and motion stability.

[0039] likeFigures 4-7 As shown, according to an embodiment of the present invention, a mechanism for detecting burrs inside a workpiece hole is provided, wherein the mounting member 41 is formed with a mounting position; a support member is disposed in the mounting position; wherein the support member is elastic, and when the insertion part 1 drives the anti-shake part 4 to move along the axial direction of the hole to be tested, at least a portion of the surface of the support member is squeezed by the hole wall, causing the support member to undergo elastic deformation.

[0040] It should be understood that the mounting member 41 is disposed on the outer peripheral surface of the insertion part 1, and one or more mounting positions specifically for fixing the support member are formed thereon. The mounting position may be a groove, slot, through hole, recess, or other adaptable structure, the geometry of which matches the root of the support member to ensure that the support member can be firmly positioned and reliably transmit load.

[0041] like Figure 4 and Figure 5 As shown, according to an embodiment of the present invention, a mechanism for detecting burrs inside a workpiece hole is provided, wherein the support member is a spring 422, the spring 422 is sleeved on the insertion part 1 and disposed in the installation position; wherein, at least part of the outer diameter of the spring 422 is gradually expanded along the axial direction of the insertion part 1 from the lens module 2 side to the control part 3 side.

[0042] In some possible implementations, the mounting location may be an annular step, a slot, a threaded interface, or other adaptable structures. The support is an elastic helical spring 422, the entirety or the main working section of which is sleeved on the outer periphery of the insertion part 1 and fixed at the mounting position of the mounting member 41. The outer diameter of the spring 422 gradually increases from the lens module 2 side to the control part 3 along the axial direction of the insertion part 1, that is, the outer diameter of the spring 422 is smaller at the end near the lens module 2, and gradually increases towards the control part 3, forming a conical, trumpet-shaped, or spindle-shaped profile.

[0043] In one specific embodiment, the spring 422 is spindle-shaped, and the mounting part 41 is two sections of round tubes, which are spaced apart along the axial direction of the insertion part 1. One section of the round tube is sleeved on the outside of the lens module 2. The two ends of the spindle-shaped spring 422 are welded and fixed to the two sections of round tubes respectively. When the spindle-shaped spring 422 enters a small hole smaller than its maximum diameter, the spring 422 structure is compressed and deformed, generating elastic force to support the lens module 2.

[0044] The progressively expanding design of the spring 422 has several advantages: First, during the insertion of the insertion part 1 into the hole to be tested, the smaller diameter end of the spring 422 contacts the hole opening first, facilitating insertion and reducing initial insertion resistance. As the insertion depth increases, the larger diameter portion of the spring 422 gradually contacts the hole wall, providing stronger radial support force. This creates a progressive constraint from weak to strong in the area where the lens module 2 is located, effectively suppressing front-end wobbling. Second, because the spring 422 itself possesses good axial and radial elasticity, when its outer surface is compressed by the hole wall, it can generate controllable compression and bending deformation, exhibiting excellent self-adaptive ability to geometric deviations within the hole, while avoiding rigid scratches or damage to the inner wall of the workpiece. Furthermore, the progressively expanding shape of the spring 422 allows it to form a distributed damping effect through multi-point contact at different axial positions under sudden stop or vibration conditions, rapidly dissipating kinetic energy and significantly improving the stability of the lens module 2 at the moment of image acquisition, thereby ensuring image clarity and improving the reliability of detecting minor defects such as burrs. Furthermore, the 422 spring, as a standard or customizable elastic element, boasts advantages such as mature manufacturing, controllable cost, and good durability. By adjusting the wire diameter, number of turns, taper angle, and material (such as stainless steel or polymer-coated metal wire), it can flexibly match different aperture ranges and detection accuracy requirements.

[0045] like Figure 6 and Figure 7 As shown, according to an embodiment of the present invention, a mechanism for detecting burrs inside a workpiece hole is provided, wherein the support member is an elastic sheet 423, and the elastic sheet 423 is disposed in the installation position; wherein, the elastic sheet 423 has a protrusion, the protrusion being adapted to abut against the hole wall.

[0046] In some possible embodiments, the elastic sheet 423 is made of a material with high elastic modulus, good fatigue life, and wear resistance, such as stainless steel sheet or composite polymer elastic material, and is in sheet or strip shape. The protrusion is a geometric feature formed by local bulges or bends on the elastic sheet 423, and its outline can be arc-shaped, spherical, wedge-shaped, or other smoothly transitioned shapes, serving as the main contact area with the inner wall of the hole to be tested.

[0047] In one specific embodiment, the mounting member 41 is a sleeve that fits onto the surface of the insertion part 1. Multiple elastic sheets 423 are evenly arranged around the mounting member 41 to form a petal-shaped structure. The mounting member 41 and the elastic sheets 423 can be integrally molded from plastic material. During the process of the insertion part 1 entering the hole to be tested, the protrusion first or mainly contacts the hole wall and undergoes elastic deformation under the radial constraint of the hole wall, thereby generating a continuous reaction force to form a stable support for the front end of the insertion part 1.

[0048] This structural design offers the following technical advantages: Firstly, the protrusion concentrates contact stress, achieving effective support with a smaller contact area and reducing insertion resistance. Secondly, due to the overall flexibility of the elastic sheet 423, when dimensional tolerances or surface irregularities exist within the hole, the protrusion can adaptively conform to the hole wall through local deformation, avoiding rigid interference and preventing scratches on the inner surface of the workpiece. Furthermore, multiple elastic sheets 423 can be evenly arranged circumferentially along the mounting part 41 (e.g., 3 to 8 sheets), ensuring a symmetrical distribution of support force and further enhancing the coaxiality and motion stability of the insertion part 1. Additionally, by adjusting the thickness, length, material stiffness of the elastic sheet 423, as well as the height and curvature of the protrusion, it can flexibly adapt to different hole diameters and detection accuracy requirements.

[0049] like Figure 1 , Figure 4 and Figure 6 As shown, a mechanism for detecting burrs inside a workpiece hole according to an embodiment of the present invention further includes: a connecting part 5, one end of the connecting part 5 being disposed on the control part 3, and the other end of the connecting part 5 being adapted to connect to a drive mechanism 7.

[0050] It should be understood that the connecting part 5, as the mechanical interface between the mechanism and the automation system, can be flexibly designed according to the actual application scenario. For example, it can adopt a standard flange, quick-change joint, threaded connection end, pin hole positioning structure, or integrated guide rail slider mating surface. This connecting part 5 not only transmits the axial thrust or tension applied by the drive mechanism 7 to achieve the precise forward and backward movement of the insertion part 1 in the test hole, but can also integrate electrical or pneumatic channels for synchronous transmission of image signals, power supply, or cleaning gas. By setting the connecting part 5, this mechanism can be easily integrated into the automated testing platform to achieve collaborative operation with the loading and unloading system, motion control system, and image processing unit.

[0051] like Figure 8 As shown, the present invention also provides an apparatus for detecting burrs inside a workpiece hole, including the above-mentioned mechanism for detecting burrs inside a workpiece hole, and further including: a worktable 6 and a drive mechanism 7; the worktable 6 has a detection area and is suitable for placing a workpiece; the drive mechanism 7 is disposed on the worktable 6; wherein the drive mechanism 7 can drive the mechanism for detecting burrs inside a workpiece hole to move in at least two directions.

[0052] It should be understood that the worktable 6 is the basic support structure of the device, on which a specially designated inspection area is provided for the stable placement of the workpiece to be tested. This inspection area can be equipped with a positioning reference, a clamping interface, or a vacuum adsorption unit to ensure that the workpiece remains in a fixed position during the inspection process, avoiding the impact of displacement or vibration on the inspection accuracy. The worktable 6 is made entirely of high-rigidity materials and undergoes precision machining and surface treatment to provide good flatness and stability.

[0053] The drive mechanism 7 is mounted on the worktable 6 and connected to the aforementioned detection mechanism via the connecting part 5. The drive mechanism 7 is configured to drive the detection mechanism to move in at least two independent directions, preferably two-dimensional motion along the horizontal direction (X-axis) and the vertical direction (Z-axis), thereby achieving automatic positioning and insertion operations for deep holes at different positions on the workpiece. In a further embodiment, the drive mechanism 7 can also be expanded into a three-axis (X / Y / Z) or multi-degree-of-freedom motion platform to adapt to the detection needs of complex layouts or multi-angle hole systems.

[0054] In some possible implementations, the drive mechanism 7 can employ a servo motor in conjunction with a ball screw, linear motor, electric slide, or industrial robot (such as a six-axis robot, which requires a movement speed of 40mm / s to balance production and inspection cycles and can quickly stop and take pictures at the shooting position), etc., possessing high positioning accuracy, repeatability, and dynamic response capabilities. The control system can precisely control the inspection mechanism to move above the target hole according to a preset program or visual guidance, and smoothly insert it to a predetermined depth along the hole axis. After completing image acquisition, it automatically withdraws, realizing fully automated operation.

[0055] According to an embodiment of the present invention, an apparatus for detecting burrs inside holes of a workpiece further includes: a conveying mechanism disposed on the surface of a worktable 6 and connected to a detection area, adapted to convey the workpiece to the detection area.

[0056] In some possible implementations, the conveying mechanism can take various forms, including but not limited to roller conveyors, belt conveyors, chain conveyors, linear vibrating feeders, or precision positioning slides, etc., with the specific selection determined based on the shape, weight, cycle time requirements, and production line layout of the workpiece. The end of the conveying mechanism is equipped with a positioning structure (such as a stop, pneumatic clamping unit, photoelectric triggering area, or vision alignment module) to ensure that the workpiece can be accurately and repeatedly positioned after entering the inspection area, providing a reliable benchmark for subsequent high-precision in-hole inspection. In actual operation, the workpiece flows into the conveying mechanism from the upstream process and is conveyed to the inspection area. When the workpiece arrival signal is triggered, the drive mechanism 7 starts, driving the aforementioned inspection mechanism to move along a preset path and insert into the hole to be inspected in the workpiece, completing image acquisition and burr judgment. After inspection, the conveying mechanism sends out the inspected workpiece and simultaneously sends in the next workpiece to be inspected, realizing a continuous and efficient automated inspection process.

[0057] Understandably, by integrating the conveying mechanism, this device not only achieves full automation of the inspection process but also significantly improves inspection efficiency and production line compatibility, making it particularly suitable for high-volume, high-paced industrial manufacturing scenarios. Furthermore, because the inspection mechanism itself has a stabilization structure close to the lens module 2, even minor vibrations or impacts during conveying and positioning can ensure image quality, guaranteeing the stability and reliability of the inspection results.

[0058] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate, and the components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
