Description

Technical Field

[0001] This utility model belongs to the field of steel pipe processing technology, and in particular relates to a marking device for steel pipes based on blockchain. Background Technology

[0002] To ensure the anti-counterfeiting capabilities of steel pipes and the integrity of data throughout the entire production, transportation, and sales process, thereby guaranteeing the immutability of information, enabling traceability and quality tracking, and facilitating verification of authenticity by downstream enterprises or regulators, blockchain technology can be used for monitoring and management.

[0003] QR code markings can now be set on the surface of steel pipes. By recognizing the QR code, the authenticity and product data of the product can be verified. Most existing laser marking equipment is designed for flat applications. However, since the surface of steel pipes is curved, compared to flat products, laser marking equipment or tooling requires additional capabilities such as the ability to adjust the angle of concentric rotation of the steel pipe and the ability to control the concentricity during rotation. Existing marking equipment suffers from problems such as inapplicability, complex control systems, complex equipment structures, and low efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a blockchain-based marking device for steel pipes. Two clamping fixtures can clamp the steel pipe via a V-shaped roller conveyor. The two relatively moving clamping seats ensure that the steel pipe, the arc-shaped opening, and the arc-shaped rail are concentric. The combination of an arc-shaped rack and gears drives the steel pipe to adjust at a certain angle, i.e., adjusting the marking points on the circumferential direction of the steel pipe surface. A laser gun head is installed via a horizontal cylinder and a lifting slide, and the laser gun head is always aligned with the steel pipe's axis. This allows adjustment of the marking points on the axial direction of the steel pipe surface and the distance between the laser gun head and the steel pipe, ensuring the marking quality and accuracy on the steel pipe.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a blockchain-based marking device for steel pipes, including a laser gun head and a set of clamping fixtures installed on the V-shaped roller conveyor of the steel pipe.

[0007] The clamping fixture includes a platform, a swing frame, and a clamping base;

[0008] The top of the platform is provided with an arc-shaped opening, and arc-shaped rails are fixed on the front and rear sides of the arc-shaped opening;

[0009] The swing frame includes an arc-shaped base, and several wheels are fixed on the front and rear sides of the bottom of the arc-shaped base. The arc-shaped base is slidably set on the arc-shaped opening through the wheels and the arc-shaped rail. An adjustment interval is formed between the wheels at both ends of the arc-shaped base and the ends of the arc-shaped rail.

[0010] An arc-shaped rack is fixed to the bottom surface of the arc-shaped seat, and a drive mechanism that cooperates with the arc-shaped rack is provided inside the platform.

[0011] Vertical beams are fixed on both sides of the top of the arc-shaped seat, vertical rails are fixed on the inner side of the vertical beams, and a bidirectional telescopic mechanism is fixed in the middle of the inner side of the vertical beams. The bidirectional telescopic mechanism is a double-headed hydraulic cylinder or a bidirectional screw mechanism.

[0012] The clamping base includes a V-shaped plate, and a top plate is fixed to the top of the V-shaped plate by several stiffeners. A crossbeam is fixed to the top of the top plate, and both ends of the crossbeam are provided with linear modules that slide with the vertical rail.

[0013] The two clamping seats are symmetrically slidably arranged between the two vertical beams and form a clamping position between them. The two telescopic ends of the bidirectional telescopic mechanism are respectively fixed to the ends of the crossbeams of the two clamping seats.

[0014] A horizontal cylinder is connected to the outer side of the platform above the clamping fixture via a lifting slide. A vertical plate is fixed to the end of the telescopic rod of the horizontal cylinder, and the laser gun head is vertically fixed to the outer side of the vertical plate.

[0015] Furthermore, the drive mechanism includes a motor reducer, which is fixed to the outside of the platform. The platform has an inner cavity, and the output shaft of the motor reducer extends into the inner cavity and is provided with a gear that meshes with an arc-shaped rack.

[0016] Furthermore, the arc-shaped rail is a C-shaped steel structure, and the open sides of the two arc-shaped rails on the arc-shaped opening are arranged opposite each other.

[0017] Furthermore, an arc-shaped beam with an L-shaped cross-section is fixed to both the front and rear sides of the bottom of the arc-shaped seat, and several wheels on the same side of the arc-shaped seat are fixed to the arc-shaped beam.

[0018] Furthermore, the width of the top plate is greater than the width of the crossbeam, and the top plate is mounted on the crossbeam by connecting hoops and fasteners. The top surface of the crossbeam is provided with a positioning groove that mates with the connecting hoops.

[0019] Furthermore, the line connecting the midpoints of the two bidirectional telescopic mechanisms is flush with the axis of the arc-shaped seat, and the laser gun head faces the axis of the arc-shaped seat.

[0020] This utility model has the following beneficial effects:

[0021] This invention uses two clamping fixtures to clamp the steel pipe via a V-shaped roller conveyor. The two relatively moving clamping seats ensure that the steel pipe, the arc-shaped opening, and the arc-shaped rail are concentric. The steel pipe can be driven to adjust a certain angle through the cooperation of the arc-shaped rack and gear, that is, to adjust the marking points in the circumferential direction on the surface of the steel pipe. The laser gun head is installed through a horizontal cylinder and a lifting slide, and the laser gun head is always aligned with the axis of the steel pipe. This allows for adjustment of the marking points in the axial direction on the surface of the steel pipe and the distance between the laser gun head and the steel pipe, ensuring the marking quality and accuracy on the steel pipe. Furthermore, the number of driving components used in the marking process is small, making it easy to control and saving costs.

[0033] Please see Figure 1-6 As shown, this utility model is a marking device for steel pipes based on blockchain, including a laser gun head 1 and a set of clamping fixtures 2 installed at the V-shaped roller conveyor 7 of the steel pipe;

The arc-shaped seat 401 is slidably mounted on the arc-shaped opening 301 through the wheels 402 and the arc-shaped rail 302. An adjustment interval is formed between the wheels 402 at both ends of the arc-shaped seat 401 and the two ends of the arc-shaped rail 302.

[0037] An arc-shaped rack 403 is fixed to the bottom surface of the arc-shaped seat 401, and a drive mechanism that cooperates with the arc-shaped rack 403 is provided inside the platform 3.

[0038] The top two sides of the arc-shaped seat 401 are fixed with vertical beams 404, the inner side of the vertical beams 404 is fixed with vertical rails 405, and the middle of the inner side of the vertical beams 404 is fixed with a two-way telescopic mechanism 406, which is a double-headed hydraulic cylinder or a two-way screw mechanism.

[0039] The clamping base 5 includes a V-shaped plate 501. A top plate 503 is fixed to the top of the V-shaped plate 501 by several stiffening plates 502. A crossbeam 504 is fixed to the top of the top plate 503. Both ends of the crossbeam 504 are provided with linear modules 505 that slide with the vertical rail 405.

[0040] Two clamping seats 5 are symmetrically slidably arranged between two vertical beams 404 and form a clamping position between them. The two telescopic ends of the bidirectional telescopic mechanism 406 are respectively fixed to the ends of the cross beams 504 of the two clamping seats 5.

[0041] A horizontal cylinder 6 is connected to the outside of the platform 3 above the clamping fixture 2 via a lifting slide 602. The end of the telescopic rod of the horizontal cylinder 6 is fixed with a vertical plate 601, and the laser gun head 1 is vertically fixed to the outside of the vertical plate 601.

[0042] Among them, such as Figure 2 and Figure 5 As shown, the drive mechanism includes a motor reducer 303, which is fixed on the outside of the platform 3. The platform 3 has an inner cavity 305. The output shaft of the motor reducer 303 extends into the inner cavity 305 and is provided with a gear 304 that meshes with the arc-shaped rack 403.

[0043] Among them, such as Figure 1-2 and Figure 5 As shown, the arc-shaped rail 302 is a C-shaped steel structure, and the open sides of the two arc-shaped rails 302 on the arc-shaped opening 301 are arranged opposite each other.

[0044] Among them, such as Figure 3 As shown, an arc-shaped beam 407 with an L-shaped cross-section is fixed on both the front and rear sides of the bottom of the arc-shaped seat 401, and several wheels 402 on the same side of the arc-shaped seat 401 are fixed on the arc-shaped beam 407.

[0045] Among them, such as Figure 1 and Figure 4 As shown, the width of the top plate 503 is greater than the width of the crossbeam 504. The top plate 503 is mounted on the crossbeam 504 by the connecting hoop 506 and fasteners. The top surface of the crossbeam 504 is provided with a positioning groove 507 that cooperates with the connecting hoop 506, so that the clamping seat 5 and the crossbeam 504 have a detachable function, and the appropriate clamping seat 5 can be selected according to the specification range of the steel pipe.

[0046] Among them, the line connecting the midpoints of the two bidirectional telescopic mechanisms 406 is flush with the axis of the arc-shaped seat 401, and the laser gun head 1 faces the axis of the arc-shaped seat 401.

[0047] The working principle of this utility model is as follows: the steel pipe passes through two steel pipe V-shaped roller conveyors 7 and two clamping fixtures 2 (initially, the two clamping seats 5 of the clamping fixtures 2 are located in the area below and above the steel pipe V-shaped roller conveyors 7, which will not interfere with the steel pipe conveying). The bidirectional telescopic mechanism 406 of the two clamping fixtures 2 is driven synchronously, which can cause the two clamping seats 5 to move relative to each other, thereby lifting and clamping the steel pipe. After clamping, the steel pipe, the arc-shaped seat 401 and the arc-shaped opening 301 are in a concentric state.

[0048] Marking can be performed directly through the laser gun head 1. If it is necessary to adjust the area in the circumferential direction of the steel pipe, the gear 304 is rotated by the motor reducer 303 (the rotation angle is controlled by the encoder). The arc rack 403 can drive the swing frame 4 and the steel pipe to adjust the angle. If it is necessary to adjust the marking area in the axial direction of the steel pipe, the extension and retraction of the laser gun head 1 is controlled by the horizontal cylinder 6, and the lifting and lowering of the laser gun head 1 is controlled by the lifting slide 602.
