Abstract
Description
Technical Field
[0001] This application relates to the field of fork joint detection technology, and more specifically, to a multi-station automated fork joint detection device. Background Technology
[0002] The sling fork is a key connecting component in mechanical transmission systems, widely used in drive shaft assemblies in automobiles, construction machinery, and rail transportation. Its main functions include transmitting torque, connecting different shaft segments, and compensating for axial and radial displacements. Its structural stability and transmission performance directly affect the operating efficiency and safety of the entire transmission system. During power transmission, the sling fork must withstand complex forces such as alternating loads and impact stresses over extended periods, making it one of the core components ensuring the normal operation of mechanical equipment.
[0003] Due to the complex working environment and harsh stress conditions of the transmission fork, its own quality is crucial to the reliability of the transmission system. If the transmission fork has problems such as out-of-tolerance inner diameter, surface or internal cracks, or material defects, stress concentration may occur during use, leading to failures such as breakage and deformation, causing equipment downtime or even safety accidents. Therefore, to ensure that the transmission fork meets design standards and usage requirements, its key dimensions, internal and surface quality must be strictly inspected to screen out qualified products and prevent unqualified parts from entering the assembly process.
[0004] Traditional forklift inspection often employs a decentralized operation model, where processes such as inner diameter inspection, flaw detection, and marking are completed on separate equipment or workstations, with forklifts moving between these workstations manually or using simple mechanical handling. This model has several drawbacks: Firstly, the dispersed layout of multiple workstations leads to a lengthy production process, and the forklifts are prone to secondary damage due to collisions and vibrations during handling. Furthermore, the high degree of manual intervention not only increases labor costs but may also affect inspection accuracy due to operational errors. Secondly, it is difficult to standardize inspection standards across workstations, and data cannot be linked in real time, leading to missed or false positives, increasing the risk of defective products being released. Additionally, the overall inspection efficiency is low, making it difficult to meet the needs of large-scale production.
[0005] Therefore, it is necessary for the inventors to design a new automated multi-station detection device for forks to overcome the above problems. Summary of the Invention

Through integrated and automated design, this device improves inspection efficiency, accuracy, and stability while reducing costs and damage risks, meeting the high-quality inspection requirements in mass production of fork sections.

[0026] Example 1, as Figures 1-9 As shown, a multi-station automated inspection device for forks includes a cabinet 1, on which a support plate 11 is mounted as the mounting base for various components. The support plate 11 integrates a feeding assembly 2, a handling assembly 3, an inner diameter inspection assembly 4, a flaw detection assembly 5, a marking assembly 6, and several support components 7. Through a rational layout, these components achieve fully automated operation of the fork from feeding, handling, multi-station inspection to marking, effectively improving inspection efficiency and consistency.
[0027] The feeding assembly 2 is fixed to the support plate 11 and arranged along the Y-axis. It includes a support frame 21, a strip-shaped feeding frame 22, an electric telescopic rod 23, and a limiting block 25. The support frame 21 provides mounting support for the strip-shaped feeding frame 22, which is used to hold several forks. The electric telescopic rod 23 is located at its bottom, and its output end is connected to the limiting block 25 and located in the channel 24 at the end of the frame facing the conveying assembly 3. The electric telescopic rod 23 drives the limiting block 25 to reciprocate within the channel 24. By moving the limiting block 25, the position of the first sequence of forks is adjusted to adapt to the conveying assembly 3 and facilitate its gripping. This structure realizes the orderly feeding of the forks, ensuring a stable and controllable feeding process and providing a continuous and reliable material supply for subsequent testing processes.
[0028] The transport assembly 3 is positioned close to the feeding assembly 2 and includes a bracket 31, a first linear module 32, a first cylinder assembly 33, a connecting frame 34, and pneumatic grippers 35. The bracket 31 is fixed to the support plate 11. The first linear module 32 is mounted on the bracket 31 along the X-axis, with its transmission end connected to the first cylinder assembly 33. Its output end is connected to several pneumatic grippers 35 via the connecting frame 34. During transport, the first linear module 32 drives the cylinder assembly to move along the X-axis, and the cylinder assembly extends and retracts along the Z-axis, driving the pneumatic grippers 35 to clamp the fork segments, sequentially transporting them from the feeding assembly 2 to the support assembly 7 at the inner diameter detection, flaw detection, and marking positions. This transport structure achieves precise positioning and rapid transfer of the fork segments through multi-axis linkage. Combined with the stable clamping of the pneumatic grippers 35, it ensures that the fork segments do not deviate during transfer between workstations, improving the continuity of the inspection process.
[0029] The inner diameter detection component 4 includes an L-shaped support plate 41, a floating base, and a measuring rod 45. The L-shaped support plate 41 is connected to the transmission end of the lead screw assembly and can move horizontally with the lead screw, facing the support assembly 7. The floating base is mounted on the support plate and includes a base plate 42, a first floating plate 43, and a second floating plate 44. The base plate 42 and the first floating plate 43 are slidably connected by a horizontal first slide rail 46, and the first floating plate 43 and the second floating plate 44 are slidably connected by a vertical second slide rail 47. The measuring rod 45 is mounted on the second floating plate 44. The base plate 42 is connected to the sliding groove 48 of the support plate by an adjusting bolt 49, which allows for adjustment of the height of the floating base. During detection, the measuring rod 45 adaptively aligns with the inner diameter of the fork under the horizontal and vertical floating adjustment of the floating base. The lead screw assembly drives the support plate to move, and the measuring rod 45 simultaneously scans the inner diameter dimension. The floating structure effectively compensates for the positional deviation when the fork is placed, ensuring precise alignment of the measuring rod 45 with the inner diameter axis, thus improving the accuracy and reliability of the inner diameter detection.
[0030] The flaw detection assembly 5 includes a second linear module 51, a height adjustment assembly 52, a transmission unit 53, a flaw detection head 55, and a drive motor 54. The second linear module 51 is positioned along the support plate 11, with its transmission end connected to the height adjustment assembly 52, allowing adjustment of the vertical height of the flaw detection head 55. The transmission unit 53 is mounted on the height adjustment assembly 52, with its output end connected to the flaw detection head 55, which is driven to rotate by the drive motor 54. During detection, the second linear module 51 moves the flaw detection head 55 along the detection direction. The height adjustment assembly 52 adjusts the spacing between the flaw detection heads 55 according to the fork segment dimensions, and the drive motor 54 controls the rotation of the flaw detection head 55, enabling multi-angle flaw detection of surface and internal defects on the fork segment. This structure, through the cooperation of the linear module and the rotary drive, allows the flaw detection head 55 to fully cover the area to be inspected on the fork segment, improving the coverage and accuracy of flaw detection and effectively identifying defects such as material cracks and inclusions.
[0031] The marking assembly 6 includes a column 61, a lifting assembly 62, a second cylinder assembly 63, a marking head 64, and a third linear module 65. The column 61 is fixed to the support plate 11 and houses the lifting assembly 62, which drives the second cylinder assembly 63 to reciprocate vertically. The cylinder output is connected to the marking head 64. The third linear module 65 is located on the support plate 11, with a support assembly 7 installed at its transmission end, positioned below the marking head 64. During marking, the transport assembly 3 transports the fork section to the third linear module 65, which then moves the inspected fork section to the marking station. The lifting assembly 62 adjusts the height of the marking head 64 to a suitable position, and the second cylinder assembly 63 drives the marking head 64 downwards, printing marking information at the designated position on the fork section. This structure, through the coordinated action of the linear module and the lifting cylinder, achieves precise positioning and depth control of the marking position, ensuring clear and standardized markings and meeting the subsequent traceability and management needs of the fork section.
[0032] Support components 7 are distributed at each inspection and marking station, including a support base 71, a double-ended cylinder 72, a floating plate 73, a clamping plate 74, and a positioning post 75. The support base 71 is fixed to the bearing plate 11. The double-ended cylinder 72 is mounted on the base, with its output end connected to the floating plate 73. A clamping plate 74 is installed inside the floating plate 73, and a positioning post 75 is installed on the base for initial positioning of the fork section. During operation, the fork section is placed on the support base 71, the positioning post 75 determines its initial position, the double-ended cylinder 72 drives the floating plate 73 to move inward, and the clamping plate 74 clamps the fork section, providing stable support. The floating plate 73 can be slightly adjusted according to the size of the fork section to adapt to the clamping requirements of different fork section specifications. This support structure, through the dual functions of positioning and clamping, ensures that the fork section remains fixed during inspection and marking, avoiding inspection errors or marking deviations caused by shaking, and improving the stability of operations at each station. Through the coordinated work of the above components, this device realizes an automated process for fork inspection from feeding and multi-station detection to marking. The structural design and functional configuration of each component are closely matched, effectively improving inspection efficiency, accuracy and equipment reliability, and meeting the needs of batch inspection of forks in industrial production.
[0033] The workflow is as follows: First, the forks to be inspected are placed in batches within the strip-shaped feed frame 22 of the feeding assembly 2. The pneumatic gripper 35 of the transport assembly 3 clamps the forks, and through the cooperation of the first linear module 32 and the first cylinder assembly 33, the forks are transported to the support assembly 7 of the inner diameter detection assembly 4. The double-ended cylinder 72 of the support assembly 7 drives the clamping plate 74 to clamp the forks, and the positioning pin 75 positions the forks. The measuring rod 45 of the inner diameter detection assembly 4, under the action of the floating base and the lead screw assembly, detects the inner diameter of the forks. After the inner diameter detection is completed, the transport assembly 3 transports the forks to the area below the flaw detection assembly. The flaw detection assembly, through the coordinated work of the second linear module 51, the height adjustment assembly 52, and the drive motor 54, performs flaw detection on the forks. After the flaw detection is qualified, the transport component 3 transports the fork section to the support component 7 below the marking component 6. The third linear module 65 adjusts the position of the fork section, and the marking head 64 of the marking component 6 descends to mark the fork section, completing the multi-station automated inspection and marking process of the entire fork section.
[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
