Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically to a tooling for inspecting the appearance of disc-shaped stamped parts. Background Technology

[0002] The stamping parts appearance inspection fixture is a special mechanical auxiliary device used to help fix and position stamped parts so as to efficiently and accurately detect whether there are undesirable appearance features such as scratches, burrs, deformation, missing punches, adhesion, and tears on their surface.

[0003] Existing fixtures for inspecting the appearance of stamped parts present challenges when inspecting disc-shaped parts for defects such as burrs, missed punches, adhesion, and tears. These issues include the difficulty in stably securing disc-shaped parts of different sizes. Traditional fixtures often employ fixed-size clamping structures, requiring frequent changes of suitable fixtures when inspecting disc-shaped parts with varying diameters and thicknesses. This is not only cumbersome and time-consuming, impacting inspection efficiency, but also prone to misalignment and movement during inspection due to insufficient fixture-part fit, thus affecting inspection accuracy. Furthermore, traditional fixtures suffer from a single inspection angle, typically employing a fixed-view inspection structure that only allows for surface inspection of disc-shaped parts. Defects on the circumference and edges are often missed or incorrectly detected, leading to incomplete identification of surface defects and compromising the accuracy and completeness of inspection results. Utility Model Content

[0004] In view of the problems existing in the appearance inspection tooling of the above-mentioned disc-shaped stamped parts, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a surface inspection fixture for disc-shaped stamped parts, which solves the problems of traditional surface inspection fixtures for stamped parts that are difficult to stably fix disc-shaped parts of different specifications, require frequent fixture changes resulting in low efficiency, and have a single inspection angle, making them prone to missed or incorrect inspections.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A fixture for inspecting the appearance of disc-shaped stamped parts includes a base, an electrical control box fixedly connected to one top end of the base, a control system fixedly connected inside the cavity of the electrical control box, a control panel fixedly connected to one top end of the electrical control box, an alarm module fixedly connected to the other top end of the electrical control box, and a first support base fixedly connected to the other top end of the base. A drive chamber is fixedly connected to the top of the first support base, a rotary table is fixedly connected to the top of the drive chamber, a circular mounting platform is rotatably connected inside the cavity of the rotary table, a drive mechanism is provided between the circular mounting platform and the drive chamber, three adjustable limit clamps are fixedly connected to the side wall surface of the circular mounting platform through three transmission mechanisms, a control board is fixedly connected to one top end of the base, a second support base is fixedly connected to the top of the control board, a vision camera is fixedly connected to the side wall of the second support base, and a counting sensor and a position sensor are fixedly connected to the top two ends of the control board, respectively.

[0007] Preferably, the drive mechanism includes a driven gear ring, a motor, and a drive gear. The driven gear ring is fixedly connected to the tube wall at one end of the circular mounting platform. The motor is fixedly connected inside the drive chamber. The drive gear is fixedly connected to the other end of the motor. The drive gear meshes with the driven gear ring.

[0008] Preferably, the transmission mechanism includes a screw, a threaded sleeve, a sliding opening, a limiting slider, and an operating handle. Three screws are rotatably connected inside the cavity of the circular mounting platform. Each screw has a threaded sleeve threadedly connected to its rod wall. The side wall of the circular mounting platform has three sliding openings, each of which is slidably connected to a limiting slider. One end of each limiting slider is fixedly connected to the side wall of the corresponding threaded sleeve, and the other end of each limiting slider is fixedly connected to the side wall of the corresponding adjustable limiting clamp. The other end of each screw passes through the side wall of the circular mounting platform and is fixedly connected to an operating handle.

[0009] Preferably, positioning magnetic blocks are fixedly connected to all four sides of the surface of the circular mounting platform through openings, and anti-slip buffer pads are fixedly connected to the surface of the circular mounting platform through openings.

[0010] Furthermore, each of the adjustable limiting clamps has an anti-slip damping pad fixedly connected to its surface. Preferably, the top two ends of the base are fixedly connected to 120-type handles, and the bottom four sides of the base are fixedly connected to bottom support feet.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model utilizes three transmission mechanisms (screw + threaded sleeve + operating handle) to drive the adjustable limit clamping plate to move radially. Combined with the clamping and fixing of the anti-slip damping pad, it eliminates the need for frequent clamp replacements. The positioning magnetic block assists in the rapid centering of parts, greatly improving the efficiency of batch inspection and solving the problems of difficult and inefficient fixing of multi-specification parts.

[0012] 2. This utility model utilizes a set drive mechanism (motor + drive gear + driven gear ring) to drive the circular mounting platform to rotate at a uniform speed, so that the surface of the part is fully exposed to the detection range of the vision camera. The set position sensor ensures that the starting position of each detection is consistent. Combined with the high-definition image acquisition of the vision camera and the automated analysis of the control system, it effectively avoids the problems of missed detection and false detection caused by traditional fixed angle detection.

[0013] 3. This utility model simplifies parameter setting and start / stop operation by using a control panel, automatically counts the number of parts detected by a counting sensor, reducing the intensity of manual operation, cushions the impact of parts placement with anti-slip buffer washers to prevent surface scratches, and uses anti-slip damping pads to replace rigid clamping with elastic clamping to prevent deformation of the outer periphery of parts, making it suitable for the inspection needs of high-precision stamped parts. The 120-type handle and bottom support feet facilitate tooling movement and stable placement, making it suitable for multi-station inspection scenarios in workshops, balancing operational convenience and parts inspection quality.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model discloses a tooling for inspecting the appearance of disc-shaped stamped parts.

[0019] This utility model provides, for example Figure 1-4 The disc-shaped stamping part appearance inspection fixture shown includes a base 1, an electrical control box 2 fixedly connected to one top end of the base 1, a control system 3 fixedly connected inside the cavity of the electrical control box 2, a control panel 4 fixedly connected to one top end of the electrical control box 2, an alarm module 5 fixedly connected to the other top end of the electrical control box 2, and a first support base 6 fixedly connected to the other top end of the base 1. A drive chamber 7 is fixedly connected to the top of the first support base 6. A rotating platform 8 is fixedly connected to the top of the drive chamber 7. A circular mounting platform 9 is rotatably connected inside the cavity of the rotating platform 8. A drive mechanism is provided between the circular mounting platform 9 and the drive chamber 7. Three adjustable limit clamps 10 are fixedly connected to the side wall surface of the circular mounting platform 9 through three transmission mechanisms. A control board 11 is fixedly connected to one end of the top of the base 1. A second support base 12 is fixedly connected to the top of the control board 11. A vision camera 13 is fixedly connected to the side wall of the second support base 12. A counting sensor 14 and a position sensor 15 are fixedly connected to the top two ends of the control board 11, respectively. The electrical control box 2 provides installation and protection space for the control system 3, control panel 4, and alarm module 5, isolating them from external dust. To prevent interference from dust and oil, and ensure stable operation of electrical components, the control system 3 integrates detection data from components such as the vision camera 13 and counting sensor 14 to automate the appearance inspection of parts, improving inspection efficiency. The control panel 4 provides operators with parameter settings, start / stop functions, and other operational interfaces, simplifying the operation process and lowering the barrier to entry. The alarm module 5 instantly triggers an alarm (audio and visual alarm) when a defective part is detected, quickly reminding operators to sort the parts and preventing defective products from flowing to the next stage. The first support base 6 provides vertical support for the drive chamber 7 and the rotating table 8, ensuring the stability of the rotation axis of the circular mounting platform 9 and guaranteeing coaxiality accuracy during part inspection. The drive chamber 7... The drive mechanism provides sealed protection to prevent the drive components from being affected by external impurities, extending their service life. The rotating table 8 provides rotational support for the circular mounting platform 9, ensuring its smooth rotation. The circular mounting platform 9 provides a placement platform for disc-shaped stamped parts, adapting to the part's circular structure. The drive mechanism drives the circular mounting platform 9 to rotate at a uniform speed, exposing the part's surface to the detection range of the vision camera 13 from all angles, solving the problem of a single detection angle. Three transmission mechanisms drive the adjustable limit clamps 10 to move synchronously or independently, adapting to disc-shaped parts of different diameters, eliminating the need for frequent clamp changes. The adjustable limit clamps 10 provide multi-point limiting and fixing from the part's outer periphery, ensuring no deviation during rotation. To improve detection stability, the control board 11 provides an installation platform for the second support 12, counting sensor 14, and position sensor 15, ensuring accurate positioning of each detection component. The second support 12 fixes the installation height and angle of the vision camera 13, aligning the camera with the part detection area to ensure image clarity. The vision camera 13 acquires real-time images of the part surface, providing image data for detecting appearance defects (such as scratches, deformation, and burrs). The counting sensor 14 automatically counts the number of detected parts, facilitating production counting and quality traceability. The position sensor 15 accurately identifies the rotation position of the circular mounting platform 9, ensuring consistent starting position for each detection and improving detection repeatability accuracy.This solves the problems of traditional stamping part appearance inspection fixtures, such as difficulty in stably fixing disc-shaped parts of different specifications, the need for frequent fixture changes leading to low efficiency, and the single inspection angle resulting in missed or incorrect inspections.

[0020] To drive the circular mounting platform to rotate stably and achieve all-around inspection of parts, such as Figure 3 and 4 As shown, the drive mechanism includes a driven gear ring 16, a motor 17, and a drive gear 18. The driven gear ring 16 is fixedly connected to the tube wall of one end of the circular mounting platform 9. The motor 17 is fixedly connected inside the cavity of the drive chamber 7. The drive gear 18 is fixedly connected to the other end of the motor 17. The drive gear 18 meshes with the driven gear ring 16. The driven gear ring 16 rotates synchronously with the circular mounting platform 9. Stable power transmission is achieved through the annular tooth surface to avoid slippage. The motor 17 provides a continuous and controllable rotational drive force. The speed can be adjusted by the control system 3 to adapt to different detection requirements. The drive gear 18 meshes with the driven gear ring 16 for transmission, resulting in high transmission efficiency, low noise, and a simple and easy-to-maintain structure. This ensures that the circular mounting platform 9 rotates at a uniform speed, eliminating blind spots on the surface of the parts.

[0021] To achieve position adjustment of the adjustable limit clamp and accommodate the fixing of parts of different specifications, such as... Figure 1-3 The transmission mechanism includes screws 19, threaded sleeves 20, sliding joints 21, limiting sliders 22, and operating handles 23. Three screws 19 are rotatably connected inside the cavity of the circular mounting platform 9. Each screw 19 has a threaded sleeve 20 threadedly connected to its wall. Three sliding joints 21 are provided on the side wall of the circular mounting platform 9, and each is slidably connected to a limiting slider 22. One end of each limiting slider 22 is fixedly connected to the side wall of the corresponding threaded sleeve 20, and the other end is fixedly connected to the side wall of the corresponding adjustable limiting clamp 10. The other end of each screw 19 passes through the side wall of the circular mounting platform 9 and is fixedly connected to an operating handle 23. The operating handle 23 is used to... The rod 19 and the threaded sleeve 20 achieve linear displacement conversion through threaded transmission, which has high transmission accuracy and can precisely adjust the position of the adjustable limit clamp 10. The sliding port 21 provides a sliding trajectory for the limit slider 22, preventing the limit slider 22 from rotating with the screw 19 and ensuring that the adjustable limit clamp 10 moves smoothly in the radial direction. The limit slider 22 connects the threaded sleeve 20 and the adjustable limit clamp 10, transmitting displacement while providing stable support for the clamp. The operating handle 23 increases the force application area of ​​the hand, making it easy for the operator to manually rotate the screw 19 without additional tools, improving the convenience of adjustment and adapting to the quick switching and fixing of parts of different specifications.

[0022] To improve the placement accuracy and stability of parts, such as Figure 1 and 3As shown, positioning magnetic blocks 24 are fixedly connected to the four sides of the surface of the circular mounting platform 9 through openings. Anti-slip buffer washers 25 are fixedly connected to the surface of the circular mounting platform 9 through openings. The positioning magnetic blocks 24 use magnetic force to attract the disc-shaped stamped parts (made of metal), assisting the parts in quick positioning and ensuring that the center of the parts coincides with the center of the circular mounting platform 9, reducing manual positioning time. The anti-slip buffer washers 25 increase the friction between the parts and the circular mounting platform 9, preventing the parts from slipping when rotating, and at the same time buffering the hard contact pressure when the parts are placed, avoiding scratches on the surface of the parts and protecting the appearance of the parts.

[0023] To enhance the fixing effect between the adjustable limit clamp and the part, and to protect the surface of the part, such as... Figure 1-3 As shown, each adjustable limit clamp 10 has an anti-slip damping pad 26 fixedly connected to its surface. The anti-slip damping pad 26 is made of a material with a high coefficient of friction, which further enhances the friction between the clamp and the outer periphery of the part, prevents the part from shifting when rotating, and ensures the stability of the inspection process. At the same time, the damping pad has a certain degree of elasticity, which can prevent the rigid clamping of the clamp from causing deformation or scratches on the outer periphery of the part, and is suitable for the inspection requirements of high-precision stamped parts.

[0024] To facilitate the movement and fixed support of tooling, such as Figure 1-4 As shown, the top two ends of the base 1 are fixedly connected to 120-type handles 27, and the bottom of the base 1 is fixedly connected to bottom support feet 28 around the bottom. The 120-type handles 27 are ergonomically designed to provide operators with convenient force points, making it easy to move the tooling in the workshop and adapt to multi-station testing needs. The bottom support feet 28 increase the contact area between the base 1 and the ground, improve the stability of the tooling placement, and prevent the tooling from sliding during the testing process. At the same time, the height of the support feet can be slightly adjusted according to the flatness of the ground to ensure that the tooling is placed horizontally and to ensure testing accuracy.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
