[0005] This utility model provides the following technical solution: a surface marking device for stainless steel pipes, comprising a U-shaped plate, a marking machine fixedly connected to the U-shaped plate, multiple electric push rods fixedly connected to the upper surface of the marking machine, a horizontal plate fixedly connected to the top of the multiple electric push rods, connecting rods fixedly connected to both ends of the lower surface of the horizontal plate, a sliding plate fixedly connected to the bottom of the two connecting rods, two symmetrical L-shaped blocks fixedly connected to the lower surface of the sliding plate, a rotating frame rotatably connected to each of the two L-shaped blocks, and a rotating wheel rotatably connected between the inner walls of the two sides of the rotating frame.

[0006] As a further embodiment of this utility model, a first fixing plate is fixedly connected to both sides of the U-shaped plate, and a second fixing plate is fixedly connected to both sides of the marking machine. Two symmetrical sliding rods are fixedly connected between the second fixing plate and the first fixing plate, and both sliding rods pass through the sliding plate and are slidably connected to it. A connecting rod passes through the second fixing plate and is slidably connected to it.

[0007] As a further embodiment of this utility model, a support plate is fixedly connected to the bottom inner wall of the U-shaped plate, and two symmetrical support blocks are fixedly connected to the upper surface of the support plate. Each support block has a V-shaped groove on its upper surface, and a rotating component for rotating the steel pipe is provided in the V-shaped groove.

[0008] As a further embodiment of this utility model, the rotating assembly includes multiple clearance grooves formed on the V-shaped groove, and a rotating rod is rotatably connected between the inner walls on both sides of the multiple clearance grooves, with a portion of the rotating rod protruding to the outside of the clearance groove.

[0009] As a further embodiment of this utility model, the L-shaped block and the rotating frame rotate through a threaded rod that passes through both of them. Both ends of the threaded rod are threaded with locking knobs, and one side of the locking knob is in close contact with the outer walls of both sides of the L-shaped block.

[0010] As a further embodiment of this utility model, one of the rotating frames is fixedly connected to a self-locking motor that causes the rotating wheel to rotate axially.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1-4 This utility model provides a surface marking device for stainless steel pipes, including a U-shaped plate 1. A marking machine 2 is fixedly connected to the U-shaped plate 1 by bolts. Multiple electric push rods 3 are fixedly connected to the upper surface of the marking machine 2 by bolts. A horizontal plate 4 is fixedly connected to the top of the multiple electric push rods 3 by bolts. Connecting rods 5 are fixedly connected to both ends of the lower surface of the horizontal plate 4 by bolts. Slide plates 6 are fixedly connected to the bottom ends of the two connecting rods 5 by bolts. Two symmetrical L-shaped blocks 13 are fixedly connected to the lower surface of the slide plates 6 by bolts. A rotating frame 14 is rotatably connected to each of the two L-shaped blocks 13. Rotating wheels 15 are rotatably connected between the inner walls of the two sides of the rotating frame 14. Through the multiple electric push rods 3 and the rotating wheels 15, the rotating wheels 15 can be brought into close contact with the steel pipe by the extension and retraction of the multiple electric push rods 3. Since the rotating wheels 15 are in contact with the steel pipe, the steel pipe can be rotated after processing, and marking operations can be performed on other parts of the steel pipe, saving the time of re-clamping and fixing and increasing the efficiency of steel pipe processing.

[0023] In this utility model, both sides of the U-shaped plate 1 are fixedly connected to the first fixing plate 10 by bolts, and both sides of the marking machine 2 are fixedly connected to the second fixing plate 16 by bolts. Two symmetrical sliding rods 17 are fixedly connected between the second fixing plate 16 and the first fixing plate 10 by bolts, and both sliding rods 17 pass through the slide plate 6 and are slidably connected to it. The connecting rod 5 passes through the second fixing plate 16 and is slidably connected to it. The sliding rods 17 can guide the slide plate 6 when it is driven up and down by activating the multi-section electric push rod 3, thereby preventing it from deflecting and causing the rotating wheel 15 to fail to make close contact with the steel pipe, increasing the stability of the movement of the slide plate 6 and increasing the stability of the device in clamping the steel pipe.

[0024] To facilitate the positioning of the steel pipe, a support plate 8 is bolted to the bottom inner wall of the U-shaped plate 1. Two symmetrical support blocks 9 are bolted to the upper surface of the support plate 8. Each support block 9 has a V-shaped groove on its upper surface. A rotating assembly is installed in the V-shaped groove to allow the steel pipe to rotate. Steel pipes of different diameters can be placed in the V-shaped groove through the support block 9 and the V-shaped groove, which facilitates the positioning of the steel pipe during placement and prevents skewing, thus affecting the accuracy of the marking. The rotating assembly includes multiple clearance grooves 11 on the V-shaped groove. A rotating rod 12 is rotatably connected between the inner walls of both sides of the multiple clearance grooves 11, and a part of the rotating rod 12 protrudes to the outside of the clearance groove 11. The clearance grooves 11 and the rotating rod 12 reduce the friction between the steel pipe and the support block 9 when the steel pipe is placed in the V-shaped groove, thus facilitating the rotation of the steel pipe.

[0025] To facilitate the fixing of steel pipes of different sizes, the L-shaped block 13 and the rotating frame 14 are rotated by a threaded rod 18 passing through them. Both ends of the threaded rod 18 are threaded with locking knobs 19, and one side of the locking knobs 19 is in close contact with the outer walls of both sides of the L-shaped block 13. Through the threaded rod 18 and the locking knobs 19 used with it, the rotating frame 14 can be easily rotated and adjusted to fix steel pipes of different sizes. One side of one of the rotating frames 14 is fixedly connected with a self-locking motor 20 that rotates the rotating wheel 15 axially by bolts. The self-locking motor 20 can rotate the rotating wheel 15 that it is used with, thereby rotating the steel pipe. No manual operation of the steel pipe is required, which increases the automation effect of the device and reduces labor costs. Rubber rings 21 are glued to the outer circumference of multiple rotating wheels 15. The outer circumference of the rubber rings 21 has grooves in a circular array. The rubber rings 21 can protect the steel pipe when fixing it and avoid damage to the steel pipe.

[0026] The use of this utility model involves the following steps:

[0027] S1: When it is necessary to mark the steel pipe, first place the steel pipe on the V-groove on the two support blocks 9 for positioning and installation. Then rotate the part of the steel pipe that needs to be marked to the top. Then start the multi-section electric push rod 3 to retract, thereby driving the horizontal plate 4 and the slide plate 6 to move down along the slide rod 17. Then rotate the wheel 15 to move down until it is in close contact with the steel pipe to fix the steel pipe.

[0028] S2: When it is necessary to mark different parts of the steel pipe, start the self-locking motor 20 to drive one of the rotating wheels 15 that works with it to rotate, thereby rotating the steel pipe in contact with it, thus facilitating the marking of different parts of the steel pipe.

[0029] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
