A device for marking defects in steel

Abstract

This utility model discloses a steel defect marking device, including a movable adjustment device, a movable block mounted on the movable adjustment device, an L-shaped plate fixedly connected to the movable block, and an output component with one end mounted on the L-shaped plate. This utility model, through the design of a buffer component and an elastic rope, provides excellent protection for the marking pen during operation. The spring and damper in the buffer component alleviate the impact force when the marking pen contacts the steel part. The elastic rope always adheres to the marking pen, preventing iron filings and dust from contaminating the pen tip, avoiding dulling or bending of the pen tip, and ensuring clear and accurate marking results. Due to the presence of the buffer component, when the marking pen contacts irregular structures such as uneven surfaces and edges of the steel part, the spring and damper buffer the marking pressure evenly, avoiding problems such as inconsistent marking depth, broken lines, or positional misalignment, thus adapting to the marking needs of steel parts with different shapes.

Description

Technical Field

[0001] This utility model relates to the field of steel inspection technology, and specifically to a steel defect marking device. Background Technology

[0002] In the steel production and processing industry, defect detection of steel parts is a crucial step in ensuring product quality. Steel defect marking devices, as an important auxiliary tool in the detection process, primarily function to promptly and accurately mark the location of defects detected on the surface or inside of steel parts. This allows for further analysis, processing, and repair of the defects, ensuring that the quality of the steel parts meets relevant standards and requirements. They are widely used in various industries such as steel manufacturing, machining, and automotive parts production.

[0003] In existing technologies, the general working principle of common steel defect marking devices is as follows: The device typically consists of a marking pen, a pen holder, and a drive mechanism. The marking pen generally uses a refill with a certain degree of hardness and smooth writing performance. The pen holder is used to hold the marking pen in place, and the drive mechanism is connected to the pen holder, controlling the movement of the pen holder through mechanical transmission, pneumatic, or electric means. After detecting a defect in the steel component, the drive mechanism moves the pen holder according to a preset program or manual operation command, causing the marking pen to mark the location of the defect in the steel component. Common marking methods include drawing lines and making dots.

[0004] However, this existing technology has several problems. First, the pen tip is exposed, making it susceptible to damage from the edges and corners of steel parts during operation. Furthermore, the steel production environment typically contains a large amount of iron filings and dust, which can adhere to the pen tip. Over time, the tip becomes dull and bent, making it difficult to clearly mark defects on the steel surface. This can result in blurred or broken marks, severely impacting the marking effect and making subsequent defect assessment and treatment difficult. Second, steel surfaces often have irregular structures such as unevenness and sharp edges, and existing marking devices lack a cushioning design when the pen tip contacts the steel. This lack of cushioning leads to uneven pressure due to hard contact with the steel surface, resulting in inconsistent marking depth, broken lines, or misaligned positions. This can lead to incorrect defect assessments, affecting the quality repair plan and reducing the overall product quality. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a steel defect marking device. Through the design of a buffer assembly and an elastic cord, the marking pen is well protected during operation. The spring and damper in the buffer assembly alleviate the impact force when the marking pen contacts the steel part. The elastic cord always adheres to the marking pen, preventing iron filings and dust from contaminating the pen tip, avoiding dulling or bending of the pen tip, and ensuring clear and accurate marking results. Due to the presence of the buffer assembly, when the marking pen contacts irregular structures such as uneven surfaces and edges of the steel part, the spring and damper buffer the marking pressure evenly, avoiding problems such as inconsistent marking depth, broken lines, or positional misalignment, thus adapting to the marking needs of steel parts with different shapes.

[0006] The purpose of this utility model is achieved by the following technical solution: a steel defect marking device, including a moving adjustment device, a moving block installed on the moving adjustment device, an L-shaped plate fixedly connected to the moving block, an output component with one end installed on the L-shaped plate, an L-shaped rotating rod installed at the output end of the output component, a sliding component installed at the other end of the L-shaped rotating rod, a buffer component installed on the sliding component, and a marking pen installed on the buffer component. The drive assembly is used to rotate the sliding assembly on the L-shaped rotating rod, thereby moving the marker pen on the buffer assembly.

[0007] In one optional embodiment, the drive assembly includes a motor fixedly connected to the L-shaped plate, a bevel gear fixedly connected to the L-shaped plate, a worm fixedly connected to the output end of the motor, a worm wheel rotatably connected to the L-shaped plate, a connecting plate rotatably connected to the bevel gear, and a connecting ring fixedly connected to the connecting plate. The motor is used to drive the worm wheel on the worm to rotate.

[0008] In one optional embodiment, the sliding assembly includes a second conical tooth rotatably connected to the other end of the L-shaped rotating rod, a second rotating cylinder fixedly connected to the second conical tooth, a limiting block slidably connected to the second rotating cylinder, a sliding cylinder fixedly connected to the limiting block, and a first rotating cylinder fixedly connected to the connecting ring, wherein the second conical tooth meshes with the first conical tooth.

[0009] In one optional embodiment, a Z-shaped groove is provided on the rotating cylinder two, and a spiral groove is provided inside the rotating cylinder one. The limiting block passes through the Z-shaped groove and is slidably connected in the spiral groove. When the worm gear rotates, the L-shaped rotating rod will drive the conical tooth two to rotate around the conical tooth one in a planetary motion.

[0010] In one optional embodiment, when the second conical tooth rotates, the second rotating cylinder will drive the limiting block on the sliding cylinder to move along the spiral groove of the first rotating cylinder, and then the limiting block will slide out or retract into the first rotating cylinder in the Z-shaped groove of the second rotating cylinder.

[0011] In one optional embodiment, the buffer assembly includes a connecting cylinder slidably connected to the sliding cylinder, a spring fixedly connected to the sliding cylinder, a damper fixedly connected to the spring, a marker pen threadedly connected to the connecting cylinder, a mounting cylinder threadedly connected to the rotating cylinder, and an elastic rope fixedly connected to the mounting cylinder. The elastic rope is provided in multiple sets and arranged in a tic-tac-to-tick pattern.

[0012] In one alternative implementation, as the marker pen approaches or moves away from the elastic cord, the grid pattern of the elastic cord gradually expands or contracts while always remaining in contact with the marker pen.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device, through the design of a buffer assembly and an elastic cord, provides excellent protection for the marker pen during operation. The spring and damper in the buffer assembly alleviate the impact force when the marker pen comes into contact with steel parts, while the elastic cord always stays in contact with the marker pen to prevent iron filings and dust from contaminating the pen tip, avoiding dulling or bending of the pen tip, and ensuring clear and accurate marking results.

[0014] 2. Due to the presence of the buffer component, when the marker pen comes into contact with irregular structures such as unevenness, corners and edges on the surface of the steel part, the spring and damper can buffer the marking pressure to make it uniform, avoiding problems such as uneven marking depth, broken lines or positional deviation, and adapting to the marking needs of steel parts with different shapes.

[0021] Please refer to Figure 1-8 A steel defect marking device includes a movable adjustment device 1, a movable block 21 mounted on the movable adjustment device 1, an L-shaped plate 22 fixedly connected to the movable block 21, an output component mounted on the L-shaped plate 22 at one end, an L-shaped rotating rod 210 mounted on the output end of the output component, a sliding component mounted on the other end of the L-shaped rotating rod 210, a buffer component mounted on the sliding component, and a marking pen 35 mounted on the buffer component. A drive component is used to drive the sliding component on the L-shaped rotating rod 210 to rotate, causing the marking pen 35 on the buffer component to move. The precise adjustment of the marking position is achieved through the cooperation of the movable adjustment device 1 and the movable block 21. The drive component, the sliding component, the buffer component, and the marking pen 35 are linked, which not only ensures that the marking pen 35 can flexibly approach or move away from the steel part, but also achieves the extension and buffering of the marking pen 35 through the cooperation of the components, solving the problems of traditional marking pens being exposed and easily damaged and lacking buffering, and improving the practicality of the device.

[0022] In a preferred embodiment of this utility model, the drive assembly includes a motor 23 fixedly connected to the L-shaped plate 22, a conical gear 29 fixedly connected to the L-shaped plate 22, a worm 24 fixedly connected to the output end of the motor 23, a worm wheel 25 rotatably connected to the L-shaped plate 22, a connecting plate 26 rotatably connected to the conical gear 29, and a connecting ring 27 fixedly connected to the connecting plate 26. The motor 23 drives the worm wheel 25 on the worm 24 to rotate, and the motor 23 provides stable power. The meshing transmission between the worm 24 and the worm wheel 25 has a speed reduction and torque increase effect, ensuring accurate and stable power transmission. The cooperation between the conical gear 29 and the connecting plate 26 and the connecting ring 27 provides a stable installation base for the sliding assembly, making the extension and retraction movement of the marker pen 35 smooth and without jamming, and improving the reliability of the marking action.

[0023] In a preferred embodiment of this utility model, the sliding assembly includes a second conical tooth 211 rotatably connected to the other end of the L-shaped rotating rod 210, a second rotating cylinder 212 fixedly connected to the second conical tooth 211, a limiting block 214 slidably connected to the second rotating cylinder 212, a sliding cylinder 213 fixedly connected to the limiting block 214, and a first rotating cylinder 28 fixedly connected to the connecting ring 27. The second conical tooth 211 meshes with the first conical tooth 29. The meshing of the second conical tooth 211 and the first conical tooth 29 converts the rotational energy of the L-shaped rotating rod 210 into the planetary motion of the second rotating cylinder 212. The limiting block 214 connects the second rotating cylinder 212 and the sliding cylinder 213, providing guidance for the extension and retraction of the sliding cylinder 213, ensuring the accuracy of the extension and retraction trajectory of the marker pen 35, and avoiding deviation.

[0024] In a preferred embodiment of this utility model, a Z-shaped groove is provided on the rotating cylinder 212, and a spiral groove is provided inside the rotating cylinder 28. The limiting block 214 passes through the Z-shaped groove and is slidably connected in the spiral groove. When the worm gear 25 rotates, the L-shaped rotating rod 210 will drive the conical tooth 211 to rotate around the conical tooth 29 in a planetary motion. The Z-shaped groove of the rotating cylinder 212 cooperates with the spiral groove of the rotating cylinder 28, so that the limiting block 214 can move along the two sets of grooves at the same time, converting the planetary rotation into the linear extension and retraction motion of the sliding cylinder 213. The structure is compact, the transmission efficiency is high, and the marking pen 35 can be quickly and accurately extended and retracted.

[0025] In a preferred embodiment of this utility model, when the conical tooth 211 rotates, the rotating cylinder 212 will drive the limiting block 214 on the sliding cylinder 213 to move along the spiral groove of the rotating cylinder 28. Subsequently, the limiting block 214 slides out or retracts into the rotating cylinder 28 in the Z-shaped groove of the rotating cylinder 212. The clear motion logic makes the sliding direction of the limiting block 214 precisely correspond to the extension and retraction state of the sliding cylinder 213, ensuring that the marking pen 35 extends stably when marking is needed and retracts into the rotating cylinder 28 in time after marking is completed, avoiding long-term exposure of the pen tip and effectively reducing damage caused by collision and dust.

[0026] Please refer to Figure 7-8 In a preferred embodiment of this utility model, the buffer assembly includes a connecting cylinder 31 slidably connected to the sliding cylinder 213, a spring 32 fixedly connected to the sliding cylinder 213, a damper 33 fixedly connected to the spring 32, a marker pen 35 threadedly connected to the connecting cylinder 31, a mounting cylinder 34 threadedly connected to the rotating cylinder 28, and an elastic rope 36 fixedly connected to the mounting cylinder 34. The elastic rope 36 is provided in multiple sets and arranged in a grid pattern. The spring 32 and the damper 33 cooperate to effectively buffer the impact force when the marker pen 35 contacts the steel part, avoiding uneven pressure caused by hard contact. The grid-arranged elastic rope 36 can always fit the surface of the marker pen 35 during the extension and retraction process, which not only plays a guiding role, but also prevents iron filings and dust from contaminating it, providing double protection for the marker pen 35.

[0027] In a preferred embodiment of this utility model, when the marker pen 35 approaches or moves away from the elastic cord 36, the lattice of the elastic cord 36 will gradually expand or contract and always fit the marker pen 35. The lattice of the elastic cord 36 can adapt to the extension and retraction of the marker pen 35 and always maintain a close fit. When the marker pen 35 extends, it does not hinder the movement. After retracting, it tightly wraps the pen tip, minimizing the risk of dust contamination and collision, while not affecting the normal use of the marker pen 35 and further extending its service life.

[0028] During operation, the moving block 21 and L-shaped plate 22 are first moved by the moving adjustment device 1 to adjust the device to the marked position corresponding to the defect in the steel part. Then the drive assembly is started, and the motor 23 on the L-shaped plate 22 outputs power to drive the worm 24 to rotate. Since the worm 24 meshes with the worm wheel 25, the worm wheel 25 rotates synchronously and drives the connecting plate 26, the connecting ring 27 and the rotating cylinder 28 to rotate.

[0029] At this time, the second bevel tooth 211 at the other end of the L-shaped rotating rod 210 meshes with the first bevel tooth 29 fixed on the L-shaped plate 22. Driven by the worm gear 25, the second bevel tooth 211 rotates planetarily around the first bevel tooth 29, thereby driving the second rotating cylinder 212 to move synchronously. Since the second rotating cylinder 212 has a Z-shaped groove and the first rotating cylinder 28 has a spiral groove, and the limiting block 214 slides through the Z-shaped groove and is slidably connected in the spiral groove, when the second rotating cylinder 212 rotates, it will drive the limiting block 214 to move along the spiral groove. At the same time, the limiting block 214 slides in the Z-shaped groove, realizing the sliding cylinder 213 sliding out or retracting, thereby driving the buffer assembly and the marker pen 35 to move closer to or away from the steel part.

[0030] When the marker pen 35 approaches the steel part, the crisscross-shaped elastic cords 36 gradually widen the crisscross openings as the marker pen 35 approaches, always maintaining contact with the surface of the marker pen 35. During the marking process, the spring 32 and damper 33 in the buffer assembly work together to buffer the impact force when the marker pen 35 contacts the steel part, avoiding damage caused by hard contact. After marking is completed, the drive assembly rotates in reverse, and the sliding cylinder 213 drives the marker pen 35 to retract into the rotating cylinder 28. The crisscross openings of the elastic cords 36 contract, removing impurities from the marker pen 35 and protecting it.

[0031] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations will be apparent to those skilled in the art without actually departing from the scope and spirit of the claims, such as variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.

[0032] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
