[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0025] This utility model provides a mechanism for detecting the outer peripheral wall of a cylindrical structural component, such as... Figures 1 to 5As shown, the cylindrical structural member 100 includes a central tube column 110 and an annular platform 120 disposed on the central tube column. The central tube column 110 has a tube shaft portion 130 exposed relative to the annular platform, and a plurality of channels 140 are provided on the outer peripheral wall of the tube shaft portion.

[0026] like Figures 1 to 5 As shown, it includes a workpiece carrier 1 and a testing fixture 2.

[0027] The workpiece carrier 1 is provided with a locking mechanism 3 that has rotational displacement. The locking mechanism 3 includes a rotating base 4 and a workpiece platform 5 set on the rotating base 4. The workpiece platform 5 is provided with a ring platform positioning groove 6 for supporting the mounting ring platform and a ring platform locking clamp 7 for radially clamping or releasing the ring platform.

[0028] The inspection fixture 2 includes a line scan camera 20 that is radially oriented toward the tube axis.

[0029] Detailed implementation process and principle explanation: When mounting the cylindrical structural component 100, its ring platform 120 is loaded into the ring platform positioning groove 6 to achieve precise positioning and mounting, and then it is locked by the ring platform locking clamp 7.

[0030] Once it is equipped with a precise positioning lock, the rotation of the rotating base 4 enables the line scan camera 20 to scan and detect the outer peripheral wall of the tube shaft 130, thereby detecting the number, diameter, and relative position of the holes 140.

[0031] After the inspection is completed, the product is released through the loosening ring locking clamp 7 for easy unloading.

[0032] In one specific embodiment, the workpiece carrier 1 includes a carrier base 10, a rotating base 4 having a movable rotational displacement on the carrier base 10, and a rotation drive source 101 provided at the bottom of the carrier base 10, the rotation drive source being connected to the rotating base in a transmission manner.

[0033] That is, the rotation of the rotating base is achieved through the rotation drive source 101, so as to meet its driving stability requirements.

[0034] In one specific embodiment, the top of the annular positioning sink 6 is provided with a tapered guide wall 61.

[0035] It meets the placement and guidance requirements when loading workpieces, making loading smoother, more stable, and with reliable loading accuracy.

[0036] In one specific embodiment, a positioning shaft extending from the annular platform is provided at the end of the central tube column away from the tube axis. The bottom wall of the ring-shaped positioning sink 6 is provided with a shaft positioning channel 62 for avoiding the positioning shaft.

[0037] When mounting the product, the positioning shaft is inserted into the shaft positioning channel 62 for precise positioning, thus improving the mounting accuracy through multiple limiting parts.

[0038] In one specific embodiment, the workpiece platform 5 includes a fixed side plate 51 connected to the rotating base, a bearing base 52 disposed at the top of the fixed side plate, and a ring positioning groove disposed on the bearing base.

[0039] The ring platform locking clamp 7 is mounted on the fixed side plate 51. The ring platform locking clamp includes a locking clamp drive source 71 and two radial locking clamps 72 that are connected to the locking clamp drive source. Each radial locking clamp has a clamping end 720 that extends through the bearing base into the ring platform positioning groove.

[0040] Specifically, the workpiece carrier 5 satisfies the linkage mounting requirements of the bearing base and the ring platform locking part 7, while also satisfying the locking requirements of the clamping end 720 through clamping and locking.

[0041] In one specific embodiment, the supporting base 52 is provided with a plurality of radial guide grooves 520 located on the outer periphery of the positioning groove of the ring platform, and any clamping end is slidably engaged in the radial guide groove.

[0042] like Figure 5 As shown, the radial guide groove 520 realizes the formation of the circumferential interval of the positioning groove 6 of the ring platform, providing a certain tolerance space, making the mounting smoother. The radial guide groove meets the clamping and guiding requirements, making the radial clamping and locking more reliable and stable after the product is mounted.

[0043] In one specific embodiment, the testing fixture 2 includes a camera mount for mounting a line scan camera, the line scan camera having adjustable lifting displacement on the camera mount.

[0044] Specifically, such as Figure 1 and Figure 2 As shown, the testing fixture 2 includes a lifting guide seat, on which a slider for adjusting the lifting displacement is provided. A line scanning camera is mounted on the slider to meet its height adjustment requirements, thereby adapting to the position adjustment and matching requirements of various products.

[0045] In one specific embodiment, the workpiece carrier 1 is equipped with an initial position detection sensor 8 for monitoring the initial rotational position and a material detection sensor 9 for oriented towards the cylindrical structure on the positioning trough of the ring platform.

[0046] Specifically, the material detection sensor 9 is used to detect whether material is being carried on the machine. Rotation is only initiated when material is detected. This material detection sensor 9 features an inclined design to meet material detection requirements and minimize the risk of misjudgment.

[0047] The initial position detection sensor 8 is used to monitor one rotation, that is, to limit the circumferential position on the product or workpiece stage 5. When the position is detected, the detection is started, and the detection ends when the position is reached after one rotation, thus ensuring that the detection completes one rotation.

[0048] In one specific embodiment, a set of radially opposite holes are provided on the outer peripheral wall of the tube shaft; that is, the set of radially opposite holes serves as an assembly feature of the product and also as a detection item, which needs to meet a circumferential starting identification, thereby meeting the needs of the actual application of the product.

[0049] Under these features and detection requirements, in this case, the sensing end of the initial position detection sensor is radially oriented towards the tube shaft. When the cylindrical structure is rotating, the initial position detection sensor has a detection position where the sensing end passes through a set of radially opposite holes.

[0050] When performing peripheral line scanning inspection of the 130mm tube shaft section, the workpiece is first rotated so that the sensing end of the initial position detection sensor captures the detection position where the sensing end passes through the two radially opposite holes. When the detection position is captured, the circumferential rotation line scanning is started and ends after one revolution. When the detection position cannot be captured, the product is judged to be NG. This serves as a detection and screening function, while also satisfying the initial sensing control of one revolution.

[0051] As described above, this invention, through the combination of rotary drive and line scanning, meets the requirements for detecting the number, diameter, and relative position of holes in the tube shaft, resulting in efficient and smooth detection operation. It enables precise positioning and locking of cylindrical structural components, ensuring stable, accurate, and reliable detection operation. It features material absence detection and specific initial position detection designs, enriching the detection items and enabling material presence triggering and precise control of rotation.

[0052] The term "comprising" or any other similar term is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus / device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent in such process, method, article, or apparatus / device.

[0053] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
