Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing, and more specifically, to a positioning device for steel pipe processing. Background Art

[0002] Steel pipes are mainly divided into round, square, rectangular and special-shaped steel pipes. Their main uses are for conveying pipelines, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc. In the process of processing steel pipes, positioning devices are required for fixing. The existing positioning device is to place the steel pipe on the workbench and then drive the clamp to move to the surface of the steel pipe. Then the surface of the clamp will contact the surfaces of both ends of the steel pipe, thereby positioning the two ends of the steel pipe. However, some steel pipes are hollow inside. When positioning the steel pipe, the force generated by the clamping can easily cause the steel pipe to deform, and if the clamping force is slightly smaller, the steel pipe will move, which will increase the processing cost and reduce the processing stability.

[0029] A positioning mechanism, which is arranged on the top of the workbench 1;

[0030] Among them, the positioning mechanism includes a moving plate 4, the number of which is two. The moving plate 4 is internally rotatably connected with a rotating block 5, a cylinder 6 is arranged on the opposite side of the rotating block 5, a fixed frame 7 is fixedly installed on the opposite side of the rotating block 5, the output shaft of the cylinder 6 extends to the inside of the fixed frame 7 and is fixedly installed with a moving bar 8, a slider 9 is movably connected to the surface of the moving bar 8, the top and bottom ends of the slider 9 are hinged with a push rod 10 and a push rod 2 11, the workbench 1 is internally movably connected with a square rod 12, a positioning block 13 is fixedly installed on the opposite side of the square rod 12, and one end of the push rod 2 11 is hinged to the bottom end of the square rod 12.

[0031] The relative motion mechanism is arranged at the left end of the workbench 1 .

[0032] The operator puts the steel pipe body 3 into the interior of the support block 2, and then drives the relative motion mechanism to make the moving plate 4 move relatively, and then the moving plate 4 drives the positioning block 13 to move relatively, so that the positioning block 13 enters the interior of the steel pipe body 3, and then the cylinder 16 can be driven to make the output shaft of the cylinder 16 pull the moving bar 8 to move. When the moving bar 8 moves, the slider 9 will move on the surface of the moving bar 8, and then the slider 9 will drive the push rod 10 and the push rod 2 11 to rotate, and then the push rod 2 11 will drive the square rod 12 to move toward each other, and then the square rod 12 will drive the positioning block 13 to move toward each other, and then the surface of the positioning block 13 will contact the inner wall of the steel pipe body 3, so that the positioning block 13 will position the steel pipe body 3.

[0033] Among them, the relative motion mechanism includes a driving component 18, which is fixedly connected to the left end of the workbench 1. The output end of the driving component 18 extends to the interior of the workbench 1 and is fixedly installed with a lead screw 19, and the surface of the lead screw 19 is movably connected with a moving block 20.

[0034] Through the design of the relative motion mechanism, the driving component 18 can be driven to rotate the screw 19, because the moving block 20 is engaged with the screw 19, and then when the screw 19 rotates, the moving block 20 moves relative to it, and the moving block 20 drives the positioning mechanism to move relative to it.

[0035] Among them, it also includes: a rotating mechanism, which is arranged on the side facing the rotating block 5;

[0037] Through the design of the rotating mechanism, after the steel pipe body 3 is positioned, the motor 17 can be driven to rotate the transmission wheel 2 15, because the transmission wheel 2 15 and the transmission wheel 1 14 are connected by the transmission belt 16. When the transmission wheel 2 15 rotates, the transmission belt 16 and the transmission wheel 1 14 will be driven to rotate, and then the transmission wheel 1 14 will drive the fixed frame 7 and the positioning block 13 to rotate. Because the opposite side of the cylinder 1 6 is fixedly connected to the transmission wheel 14, the cylinder 1 6 will also rotate.

[0038] There are two support blocks 2 , and the support blocks 2 are designed to be symmetrical about the center of the workbench 1 .

[0041] The moving mechanism includes a moving groove 21, which is opened at the top of the workbench 1. A driving component 22 is fixedly installed on the top of the workbench 1. A lead screw 23 is fixedly installed on the output end of the driving component 22. The surface of the lead screw 23 is movably connected to a moving plate 24 located inside the moving groove 21.

[0042] Through the design of the moving mechanism, when cleaning the surface of the steel pipe body 3, the driving component 22 can be driven to rotate the screw 23. Since the screw 23 is engaged with the moving plate 24, the screw 23 drives the moving plate 24 to move, and then the moving plate 24 drives the cleaning component to move. Through the movement of the cleaning component, the entire surface of the steel pipe body 3 is cleaned.

[0043] Among them, it also includes: a cleaning component, which is arranged on the top of the second moving plate 24;

[0045] Through the design of the cleaning block 26, the cylinder 2 25 can be driven so that the output shaft of the cylinder 25 pushes the cleaning block 26 down, and then the surface of the cleaning block 26 will contact the surface of the steel pipe body 3. Through the rotation of the steel pipe body 3, the cleaning block 26 cleans the surface of the steel pipe body 3.

[0046] The working principle and use process of this utility model:

[0047] First, the operator can place the steel pipe body 3 inside the support block 2, and then drive the driving component 18 to rotate the screw 19. When the screw 19 rotates, it will drive the moving block 20 and the moving plate 4 to move, and then the moving plate 4 will drive the positioning block 13 to move, so that the positioning block 13 enters the interior of the steel pipe body 3, and then drive the cylinder 6 to make the output shaft of the cylinder 6 pull the moving bar 8 to move toward each other. In the process of moving the moving bar 8, the slider 9 will move on the surface of the moving bar 8, and then the slider 9 will drive the push rod 10 and the push rod 2 11 to rotate, because one end of the push rod 2 11 is hinged to the square rod 12, so that when the push rod 2 11 rotates, it will push the square rod 12 to move toward each other, and then the square rod 12 will drive the positioning block 13 to move toward each other, and then the surface of the positioning block 13 will contact the inner wall of the steel pipe body 3, so that the positioning block 13 is against the steel pipe The main body 3 is positioned, and then the motor 17 can be driven to rotate the transmission wheel 2 15, so that the transmission wheel 2 15 drives the transmission belt 16 and the transmission wheel 1 14 to rotate, and then the transmission wheel 1 14 will drive the rotating block 5 and the fixed frame 7 to rotate, and then the fixed frame 7 will drive the positioning block 13 and the steel pipe body 3 to rotate. During the rotation of the steel pipe body 3, the cylinder 2 25 is driven to lower the cleaning block 26, so that the surface of the cleaning block 26 contacts the surface of the steel pipe body 3, and then through the rotation of the steel pipe body 3, the cleaning block 26 will clean the rust on the surface of the steel pipe body 3. During the cleaning process, the driving component 22 is driven to rotate the lead screw 23, so that the lead screw 23 drives the moving plate 24 to move. When the moving plate 24 moves, the cleaning block 26 will move with it, and then the cleaning block 26 will clean the entire surface of the steel pipe body 3. After the cleaning is completed, the operator can process the steel pipe.
