Description

Technical Field

[0001] This utility model relates to the field of metal rod processing technology, specifically to a metal rod testing device. Background Technology

[0002] In modern industrial production, metal rods are important structural components and parts, widely used in many fields such as machinery manufacturing, aerospace, and automotive industries. Their surface quality is directly related to the performance, safety, and service life of the products. Therefore, the detection of external damage to metal rods is a crucial step in the production process.

[0003] Currently, traditional methods for detecting external damage to metal rods mostly rely on manual operation. Operators need to manually place the metal rod onto the testing table to complete the inspection. However, the fixed end of the metal rod cannot be inspected, so it is necessary to manually rotate the metal rod to adjust its direction in order to achieve a comprehensive inspection of the metal rod's surface and ensure inspection quality. However, this highly manual inspection mode has significant drawbacks: on the one hand, manual operation makes it difficult to maintain the continuity of the inspection process, and a lot of time is consumed in the placement, rotation, and removal of the metal rod; on the other hand, manual operation is inefficient, which not only increases labor costs but is also prone to errors in inspection results due to factors such as fatigue, making it difficult to meet the needs of large-scale, high-efficiency production in modern industry. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a metal rod detection device, comprising a rod-moving assembly mounted on an operating table, two sets of visual inspection devices, and multiple sets of support platforms;

[0005] The multiple sets of placement platforms are arranged from left to right as follows: a pre-placement platform, a preparation platform, two sets of rotating platforms that are respectively opposite to the corresponding visual inspection devices, and a clamping platform located between the two sets of rotating platforms.

[0006] The lever assembly includes a three-axis moving part mounted on the operating table, and multiple clamping cylinders and multiple pneumatic rotary gripper devices are installed on the lifting end of the three-axis moving part.

[0007] Furthermore, the three-axis moving part includes a push cylinder mounted on the operating table and a lower moving plate slidably connected to the push cylinder. A linear module is mounted on the lower moving plate and a moving plate slidably connected to and fixed to the moving end of the linear module. An upward push cylinder is mounted on the moving plate and extends through the lower moving plate. The piston rod of the upward push cylinder is fixed to the upward push plate. The clamping cylinder and the pneumatic rotating gripper device are both mounted on the upward push plate.

[0008] Furthermore, four sets of guide rods arranged in a trapezoidal pattern are fixed on the movable plate, and the guide rods pass through the upper push plate.

[0009] Furthermore, the upper push plate is L-shaped and has multiple inner plates fixed on its inner side.

[0010] Furthermore, the rotary table includes a support platform, on which a belt-driven transmission device for driving the transmission shaft to rotate is mounted, and a rotating cylinder seat is mounted on the top of the transmission shaft.

[0011] Furthermore, the clamping platform includes a vertical platform, a recessed platform is fixed on the vertical platform, and a push cylinder is installed at the bottom. The piston rod of the push cylinder is fixed with a push clamping plate that is opposite to the concave surface of the recessed platform.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This metal rod inspection device automatically transports the metal rod between the pre-placement stage, preparation stage, rotary stage, and clamping stage via a three-axis moving part using a clamping cylinder and pneumatic rotary gripper in the rod-moving assembly. This eliminates the need for manual intervention, significantly improving the continuity of the inspection process and avoiding time losses caused by manual operation. Two sets of vision inspection devices, working in conjunction with the rotary stage rotation and the pneumatic rotary gripper, can automatically complete a comprehensive inspection of the metal rod's circumferential surface. This fully automated inspection process reduces manual intervention, avoids inspection errors caused by human fatigue, and meets the high-efficiency requirements of large-scale industrial production.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 The metal rod detection device in this embodiment includes a rod-moving assembly 1 mounted on an operating table, two sets of visual inspection devices 2 mounted opposite to the rod-moving assembly 1, and a pre-placement platform 3, a preparation platform 4, two sets of rotating platforms 5, and a clamping platform 6 located between the rod-moving assembly 1 and the visual inspection devices 2, arranged from left to right. The rod-moving assembly 1 includes a three-axis moving part mounted on the operating table. The lifting end of the three-axis moving part is equipped with three sets of clamping cylinders 16 and three sets of pneumatic rotating gripper devices 17, as well as two sets of visual inspection devices 2.

[0021] In the above structure, the three-axis moving part can realize the precise displacement of the rod-shifting assembly in the horizontal X and Y axes and the vertical Z axis, meeting the material handling needs between different workstations. The first-end clamping cylinder moves the metal rod from the outside to the pre-placement stage. After the material is gripped by the second set, it moves to the preparation stage via the X and Y axes, and then descends via the Z axis to complete the placement, ensuring the orderly flow of materials between workstations. The designated positions of the two sets of rotating tables or clamping stages, in conjunction with the feedback from the vision inspection device, complete the inspection. At the same time, when the rod-shifting assembly moves the material on the first set of rotating tables to the clamping stage, the pneumatic rotating gripper will realize the rotation of the material during the handling process. When handling between the two sets of rotating tables, the rotating gripper will adjust the flipping of the material, and the overall inspection of the material will be completed in conjunction with the inspection of the vision inspection device.

[0022] Among them, such as Figure 4 In this system, the rotary table 5 includes a support platform 51 fixed to the operating table. A belt-driven transmission device 52 is installed on the support platform 51 to drive the transmission shaft 53 to rotate. A rotating drum seat 54 for holding materials is fixed to the top of the transmission shaft 53. By driving the transmission shaft to rotate through the belt-driven transmission device, the rotating drum seat rotates accordingly. In conjunction with the vision inspection device, a 360-degree inspection of the material can be completed.

[0023] In addition, such as Figure 3In this assembly, the clamping platform 6 includes a vertical platform 61 fixed to the operating table. A recessed platform 62 is fixed to the top of the platform 61, with a V-shaped concave surface. An opening is formed on the platform 61, and a push-pull cylinder 63 is installed at its bottom. The piston rod of the push-pull cylinder 63 is fixed to a push-pull clamping plate 64 located in the opening and opposite the V-shaped concave surface of the platform 62. After the metal rod completes its first damage inspection, the rod-shifting assembly flips it over, placing the other end upwards between the recessed platform and the push-pull clamping plate. The push-pull cylinder then pushes the push-pull clamping plate to clamp and position the flipped rod, preparing it for a second inspection. The rod-shifting assembly then transfers the rod away, completing the inspection of the previously uninspected end.

[0024] like Figure 2 The moving rod assembly 1 includes a lower moving plate 11 slidably connected to the operating table, and a push cylinder 12 installed to drive the lower moving plate 11 to move back and forth. The lower moving plate 11 also has an elongated hole, a moving plate 18 slidably connected to it, and a linear module 13 installed to drive the moving plate 18 to move left and right. The top of the moving plate 18 is fixed with four sets of guide rods 15, and an upper pushing cylinder 14 is installed that passes through the elongated hole and the operating table. The operating table has a rectangular hole adapted to the forward, backward, left and right movement of the upper pushing cylinder 14. An upper pushing plate 19 is inserted between the guide rods 15 and fixed to the piston rod of the upper pushing cylinder 14. The upper pushing plate 19 is L-shaped and has no fewer than six inner plates 20 fixed on its inner side. The top of the upper pushing plate 19 is equipped with three sets of clamping cylinders 16 and three sets of pneumatic rotating gripper devices 17.

[0025] The lowering plate slides back and forth driven by a pusher cylinder. The rectangular holes on the operating table provide space for the upper pushing cylinder to move back and forth. A linear module drives the moving plate to slide left and right. The upper pushing cylinder moves up and down through elongated and rectangular holes. Together with the upper pushing plate, this allows the three sets of clamping cylinders and the pneumatic rotary gripper device to move freely in three-dimensional space. The rectangular holes on the operating table allow the upper pushing cylinder to move back and forth with the lowering plate, while also providing leeway for left and right movement. The elongated holes on the lowering plate ensure that the upper pushing cylinder is not interfered with during left and right movement. This design allows the movements in the three directions to be independent yet coordinated, avoiding motion interference. Guide rods distributed on the upper pushing plate provide stable guidance for lifting and lowering movements, reducing the impact of lateral forces on the cylinder piston rod, and extending the cylinder length. The lifespan is extended, and the overall structural rigidity is improved, especially when gripping heavier materials, effectively reducing swaying and ensuring positioning accuracy. The inner plate is distributed inside the upper push plate, enhancing structural strength and reducing deformation caused by long-term stress, ensuring the stability of the gripper device. The moving rod assembly can cover multiple workstations such as the pre-placement table, preparation table, rotary table, and clamping table, realizing efficient material flow between different processes. The vertical lifting function, combined with the rotating gripper, can complete compound actions such as gripping, lifting, rotating, and placing materials. Thus, after completing the first set of inspections, when placing the material on the clamping table, the corresponding pneumatic rotating gripper device flips the material for the second set of inspections, thereby completing a comprehensive inspection of the metal rod and improving inspection quality.

[0026] The working principle of the above embodiments is as follows:

[0027] The first clamping cylinder of the rod-moving assembly grips the metal rod from the outside and transfers it to the pre-placement stage. Subsequently, the second set of clamping cylinders grips the metal rod on the pre-placement stage and moves it to the preparation stage using the X and Y axes of the three-axis moving part. Then, it descends via the Z axis to complete the placement, so that the metal rod flows in the sequence of pre-placement stage - preparation stage - rotary table - clamping stage - another rotary table. The lower moving plate slides back and forth under the drive of the push cylinder, and the moving plate slides left and right through the linear module. The upper pushing cylinder completes the up and down movement by passing through the elongated hole and the rectangular hole. The three directions of movement are independent yet coordinated to avoid interference. This is combined with the guidance of four sets of guide rods and the reinforcement of the upper pushing plate and the inner plate. The structural strength ensures the stable operation of the rod-shifting assembly. The belt-driven transmission device of the rotary table drives the transmission shaft to rotate, which in turn rotates the rotating cylinder seat. This, combined with the vision inspection device, enables 360-degree inspection of the metal rod. The top-push cylinder of the clamping table pushes the top-push clamping plate, which cooperates with the concave platform to clamp and position the metal rod after it is flipped, facilitating the transfer of the rod-shifting assembly for secondary inspection. Two sets of vision inspection devices monitor the status of the metal rod in real time. When the rod-shifting assembly is moved between workstations, the pneumatic rotating gripper device adjusts the metal rod according to inspection requirements, such as flipping it over. Combined with vision inspection, this ensures that all parts of the metal rod are inspected, improving the comprehensiveness and accuracy of the inspection.
