[0015] Compared with the prior art, the present utility model provides a spiral steel pipe marking device, which has the following

[0016] Beneficial effects:

[0017] 1. For this spiral steel pipe marking device, by installing a screw rod inside the machine tool, the screw rod rotates under the action of the first motor. Thus, under the threaded connection of the screw rod and the traction seat, the traction seat moves horizontally inside the machine tool. The movement of the traction seat can drive the fixing mechanism to move. When the fixing mechanism is activated, it can clamp one end of the steel pipe. Therefore, in cooperation with the traction mechanism, the longer steel pipe can be pulled to the lower part of the marking mechanism. Therefore, when marking a longer spiral steel pipe, this device is more time-saving and labor-saving, and it is convenient to position the steel pipe.

[0018] 2. The spiral steel pipe marking device can stably clamp the spiral steel pipe through the fixing mechanism installed inside the traction mechanism. Under the action of the second motor of the fixing mechanism, the gear can be driven to rotate. Due to the meshing of the gear and the toothed disc, the toothed disc rotates. Under the action of the arc-shaped groove formed on the surface of the toothed disc, the connecting rod can be pushed to drive the clamping block to move towards the center inside the fixed disc. The movement of the clamping block can achieve the stable clamping of the spiral steel pipe. At the same time, due to the limit rod and the clamping seat installed under the movable seat of the marking mechanism, the clamping seat can move downward synchronously with the movable seat under the action of the air cylinder, and then the spiral steel pipe can be tightly fixed by the clamping seat, so as to cooperate with the fixing mechanism to make the spiral steel pipe more stable during the marking process, thereby improving the marking accuracy.

[0025] Please refer to Figures 1-4 , in this embodiment: A spiral steel pipe marking device includes a machine tool 1, an installation frame 5 is arranged on the outer surface of the machine tool 1, and an air cylinder 6 is arranged on the upper surface of the installation frame 5;

[0026] Inside the machine tool 1, a traction mechanism 2 is provided. On one side of the traction mechanism 2, a fixed frame 3 is provided. On one side of the fixed frame 3, a fixing mechanism 4 is provided. Below the cylinder 6, a marking mechanism 7 is provided. Inside the fixing mechanism 4, an arc-shaped groove 8 is provided. Inside the arc-shaped groove 8, a connecting rod 9 is provided. At one end of the connecting rod 9, a clamping block 10 is provided.

[0027] The fixing mechanism 4 includes a second motor 41, a gear 42, a fixed disk 43, and a toothed disk 44. On one side of the second motor 41, a gear 42 is drivingly connected. Below the gear 42, a toothed disk 44 is meshingly connected. The fixed disk 43 is fixedly installed with the traction mechanism 2. The fixing mechanism 4 is used for clamping and fixing the spiral steel pipe.

[0028] Please refer to Figure 1 and Figure 2 In this embodiment, the traction mechanism 2 includes a first motor 21, a screw rod 22, and a traction seat 23. On one side of the first motor 21, a screw rod 22 is drivingly connected. On the outer surface of the screw rod 22, a traction seat 23 is threadedly connected.

[0029] In the above embodiment, under the action of the first motor 21, the screw rod 22 located inside the machine tool 1 rotates. Therefore, under the cooperation of the traction seat 23 and the screw rod 22, the horizontal movement of the fixing mechanism 4 located inside the traction seat 23 is realized.

[0030] Specifically, the screw rod 22 is movably connected inside the machine tool 1. The fixed frame 3 is fixedly installed on one side surface of the traction seat 23. The connecting block fixedly installed below the traction seat 23 is threadedly connected with the screw rod 22.

[0031] Since a connecting block is installed below the traction seat 23, the horizontal movement of the traction seat 23 can be realized under the cooperation of the connecting block and the screw rod 22. Through the linkage cooperation of the traction mechanism 2 and the fixing mechanism 4, the traction and loading of a longer spiral steel pipe can be realized.

[0032] Please refer to Figure 1 and Figure 4 In this embodiment, the marking mechanism 7 includes a movable seat 71, a limiting rod 72, a clamping seat 73, a return spring 74, and a laser marking head 75. Inside one side of the movable seat 71, a limiting rod 72 is sleeved. Above one side of the clamping seat 73, a return spring 74 is fixedly connected. In the middle below the movable seat 71, a laser marking head 75 is fixedly installed.

[0033] In the above embodiment, the movable seat 71 can drive the laser marking head 75 to move. Under the action of the limiting rod 72 and the return spring 74, the clamping seat 73 can move synchronously with the movable seat 71, so as to fix the spiral steel pipe.

[0034] Further, a movable seat 71 is fixedly connected below the cylinder 6. There are two sets of limit rods 72, and the bottom ends are fixedly installed on the upper surfaces of both sides of the card seat 73. A through groove is provided in the middle of the card seat 73.

[0035] Under the action of the cylinder 6, the movable seat 71 can move vertically inside the mounting frame 5. Through the movement of the movable seat 71, the laser emitted by the laser marking head 75 can pass through the through groove of the card seat 73 to perform a marking operation on the spiral steel pipe.

[0036] Please refer to Figure 1 、 Figure 2 and Figure 3 In this embodiment, the fixed disk 43 is fixedly installed inside the traction mechanism 2. The fixed frame 3 is fixedly installed with the traction mechanism 2, and the second motor 41 is fixedly installed with the fixed frame 3. Grooves are circumferentially formed on the surface of the fixed disk 43. The connecting rod 9 is slidably connected to the arc-shaped groove 8 and the groove. The clamping block 10 is movably connected to the fixed disk 43.

[0037] In the above embodiment, the second motor 41 can drive the gear 42 to rotate, and then the toothed disk 44 rotates. The connecting rod 9 drives the clamping block 10 located inside the fixed disk 43 to move towards the center under the action of the arc-shaped groove 8, so as to clamp and fix the spiral steel pipe.

[0038] It should be supplemented that the mounting frame 5 is fixedly installed with the machine tool 1. The bottom end of the cylinder 6 is fixedly connected to the marking mechanism 7, and the traction mechanism 2 is fixedly connected to the fixing mechanism 4.

[0039] The working principle and usage process of the present utility model: The operator starts the first motor 21 to make the screw rod 22 rotate, so that the traction seat 23 drives the fixing mechanism 4 to move to the other side of the machine tool 1. After placing one end of the steel pipe in the through hole of the fixing mechanism 4, the second motor 41 can be started to drive the gear 42 to rotate, so that the toothed disk 44 rotates. Under the action of the arc-shaped groove 8 on the surface of the toothed disk 44, the connecting rod 9 drives the clamping block 10 located inside the fixed disk 43 to move towards the steel pipe, so as to clamp and fix the steel pipe. Then, by reversing the first motor 21 of the traction mechanism 2, the traction mechanism 2 cooperates with the fixing mechanism 4 to pull the steel pipe to directly below the marking mechanism 7. By starting the cylinder 6, the movable seat 71 drives the card seat 73 and the laser marking head 75 to move downward synchronously. The downward movement of the card seat 73 can cooperate with the fixing mechanism 4 under the reaction force of the return spring 74 to firmly fix the steel pipe. By starting the laser marking head 75, the steel pipe can be marked. After the marking is completed, the blanking can be completed through the reverse operation.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
