This invention effectively improves the uniformity and accuracy of laser marking by installing an automatic focusing device, and further improves the accuracy of laser marking by installing a spring shock absorption device, ensuring the quality of laser marking.

[0004] However, this utility model has the following problems in actual use:

[0005] 1. When using the above equipment, it is inconvenient to adjust and fix the equipment according to different sizes of pipes, which reduces the applicability and flexibility of the equipment;

[0006] 2. When the marking head of the above equipment is damaged or needs to be replaced, it is inconvenient to disassemble the marking head, which will reduce the working efficiency and convenience of the equipment.

[0007] Therefore, there is an urgent need for a marking device for pipe surfaces to solve the above problems. Utility Model Content

[0008] In order to overcome the above-mentioned defects of the prior art, the present invention provides a marking device for pipe surface to solve the problems existing in the background art.

[0009] This utility model provides the following technical solution: a marking device for pipe surfaces, including a base:

[0010] A support frame is fixed to the upper end of the base. An electric conveyor belt is installed in the middle of the base. Motors are installed at both ends of the base, and lead screws are fixed to the output ends of the motors. Grooves are opened at both ends of the base, and sliding plates are slidably inserted into the grooves. A positioning plate is fixed to the upper end of the sliding plates. An electric push rod is installed at the upper end of one side of the support frame, and a round block is fixed to the lower end of the electric push rod. A positioning ring is slidably fitted on the surface of the round block, and an adjusting rod is slidably inserted into the positioning ring. The marking machine body is fixed to the lower end of the positioning ring.

[0011] Preferably, the lead screw bearing is connected to one side of the groove, and a fixing rod is fixed to the other side of the groove. With the cooperation of the fixing rod, when the sliding plate moves, the positioning plate can be prevented from shifting or tilting, thereby improving the stability of the equipment to a certain extent.

[0012] Preferably, the inner ends of the sliding plate are respectively in contact with the surfaces of the lead screw and the fixed rod, and the movement position of the sliding plate can be restricted through the above operation.

[0013] Preferably, the lower end of the positioning plate is in contact with the upper surface of the base, and an anti-slip pad is provided on one side of the positioning plate. With the cooperation of the anti-slip pad, when the positioning plate is in contact with the surface of the pipe, the friction between the positioning plate and the surface of the pipe can be increased, while protecting the surface of the pipe from wear.

[0014] Preferably, a fixing block is fixed on one side of the positioning plate, and a positioning bolt is connected to the internal thread of the fixing block. A rubber pad is provided at the lower end of the positioning bolt. By rotating the positioning bolt, the lower surface of the rubber pad is brought into contact with the upper surface of the base, thereby fixing the position of the positioning plate.

[0015] Preferably, a limiting ring is provided at one end of the adjusting rod near the bottom, and the limiting ring is in contact with the inner surface of the circular block. By using the limiting ring, the movement position of the adjusting rod can be fixed and restricted, while preventing the adjusting rod from moving out of the positioning ring.

[0016] Preferably, a storage block is fixed to one end of the positioning ring, and the interior of the storage block is adapted to the surface of the limiting ring. Through the above operation, one end of the adjusting rod can be stored, thereby avoiding the situation where the round block is inconvenient to disassemble.

[0017] Preferably, the other end of the positioning ring is slidably engaged with a rotating block, and the interior of the rotating block is threadedly connected to the bottom surface of one end of the adjusting rod. By using the above operations in combination, the positions of the adjusting rod and the rotating block can be fixed.

[0018] The technical effects and advantages of this utility model are as follows: This utility model uses a starting motor to drive a lead screw to rotate, which causes the sliding plate to move the positioning plate inward or outward at the upper end of the base. Simultaneously, the use of a fixing rod makes the movement of the positioning plate more stable. When the positioning plate moves to the appropriate position, the positioning bolt can be rotated downward so that the lower end surface of the positioning bolt is in contact with the upper end surface of the base, thereby fixing the position of the positioning plate and thus fixing the position of the pipe. Through the above operations, the equipment can be adjusted according to different sizes of pipes to fix the position of the pipes, thereby improving the applicability and flexibility of the equipment.

[0019] By rotating the rotating block, the adjusting rod is disengaged from the interior of the rotating block. Then, the adjusting rod is moved to one end outward, so that one end of the adjusting rod moves into the interior of the receiving block. When the position of the limiting ring is in contact with the inner wall surface of the receiving block, the marking machine body can be moved downward to drive the positioning ring to disengage from the surface of the round block. This allows for the disassembly of the electric push rod and the marking machine body. When the marking machine body is damaged and needs repair or replacement, it can be disassembled and processed through the above operation. The above operation method is relatively simple and can improve the working efficiency and convenience of the equipment. Attached Figure Description

[0026] 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. The material processing involved in 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.

[0027] Example 1

[0028] like Figures 1 to 3 As shown, this embodiment proposes a marking device for pipe surface, including a base 1, a support frame 2 fixed at the upper end of the base 1, an electric conveyor belt 3 installed at the middle position of the base 1, a motor 4 installed at both ends of the base 1, and a lead screw 5 fixed at the output end of the motor 4. Grooves are opened at both ends of the base 1, and a sliding plate 7 is slidably inserted into the groove. A positioning plate 8 is fixed at the upper end of the sliding plate 7. The lead screw 5 is bearing connected to one side of the groove, and a fixing rod 6 is fixed on the other side of the groove. The inner ends of the sliding plate 7 are respectively in contact with the surfaces of the lead screw 5 and the fixing rod 6. The lower end of the positioning plate 8 is in contact with the upper surface of the base 1. An anti-slip pad is provided on one side of the positioning plate 8, and a fixing block is fixed on one side of the positioning plate 8. The fixing block is internally threaded with a positioning bolt 9, and a rubber pad is provided at the lower end of the positioning bolt 9.

[0029] In this embodiment, the base 1 and support frame 2 are used together to place and support the pipe. When the pipe is placed on the upper end of the electric conveyor belt 3, the electric conveyor belt 3 can be started to move the position of the pipe, thereby improving the convenience of the equipment. The motor 4 drives the lead screw 5 to rotate, thereby causing the sliding plate 7 to move the positioning plate 8 inward or outward. The fixed rod 6 is used to support the position of the sliding plate 7 during movement, thereby improving the stability of the positioning plate 8 during movement. The positioning bolt 9 is rotated to move downward inside the fixed block. When the rubber pad is in contact with the upper surface of the base 1, the position of the positioning bolt 9 can be fixed. The protective pad is used to fix the position of the pipe and protect the surface of the pipe from wear.

[0030] Example 2

[0031] like Figure 4 and Figure 5As shown, based on the same concept as the above embodiment, this embodiment also proposes: an electric push rod 10 is installed on the upper end of one side of the support frame 2, and a round block 11 is fixed at the lower end of the electric push rod 10. A positioning ring 12 is slidably sleeved on the surface of the round block 11, and an adjusting rod 13 is slidably inserted inside the positioning ring 12. A marking machine body 16 is fixed at the lower end of the positioning ring 12. A limiting ring is provided at one end of the adjusting rod 13 near the bottom, and the limiting ring is in contact with the inner surface of the round block 11. A storage block 14 is fixed at one end of the positioning ring 12, and the inside of the storage block 14 is adapted to the surface of the limiting ring. A rotating block 15 is slidably engaged at the other end of the positioning ring 12, and the inside of the rotating block 15 is threadedly connected to the bottom surface of one end of the adjusting rod 13.

[0032] In this embodiment, the electric push rod 10 can drive the marking machine body 16 to move up or down, thereby marking pipes of different sizes and improving the applicability of the equipment. By moving the adjusting rod 13 so that it passes through the inside of the circular block 11 and is close to the inside of the rotating block 15, and then rotating the rotating block 15 to fix the position of the adjusting rod 13, the positions of the circular block 11 and the positioning ring 12 can be fixed, and the positions of the electric push rod 10 and the marking machine body 16 can be fixed at the same time. With the cooperation of the storage block 14, one end of the adjusting rod 13 can be stored, thereby avoiding the situation where the circular block 11 and the positioning ring 12 are difficult to disassemble. With the cooperation of the positioning ring 12 and the rotating block 15, one end of the rotating block 15 is engaged inside one end of the positioning ring 12, thereby preventing the rotating block 15 from being lost when not in use, thereby improving the convenience of the equipment.

[0033] Working principle: When using the equipment, first place the pipe on the upper end of the electric conveyor belt 3, and then start the electric conveyor belt 3 to drive the pipe to be marked so that the position corresponds to the lower end of the marking machine body 16. Then start the motor 4 to drive the lead screw 5 to rotate. At the same time, the sliding plate 7 moves synchronously on the surface of the fixed rod 6, thereby driving the positioning plate 8 to move so that the surface of the anti-slip pad is in contact with the surface of the pipe. Then rotate the positioning bolt 9 so that its lower end surface is in contact with the upper end surface of the base 1, thereby fixing the position of the positioning plate 8, and thus fixing the position of the pipe.

[0034] When the marking machine body 16 needs to be replaced or disassembled, the adjusting rod 13 is disengaged from the interior of the rotating block 15 by rotating the rotating block 15. At this time, one end of the adjusting rod 13 can be moved into the interior of the receiving block 14. At this time, the surface of the adjusting rod 13 is disengaged from the interior of the round block 11. Then, the marking machine body 16 can be moved downward to drive the positioning ring 12 to disassemble from the electric push rod 10. Thus, the positions of the electric push rod 10 and the marking machine body 16 are disassembled. The motor 4 and the electric push rod 10 used in this application are products that can be directly purchased on the market. Their principles, connection methods and control methods are all existing technologies known to those skilled in the art, so they will not be described in detail here. The above is the complete working principle of this utility model.

[0035] Finally, the following points should be noted: First, 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 connections, or internal connections between two components, or direct connections.
