Description

Technical Field

[0001] The utility model relates to the field of steel pipe manufacturing and processing, in particular to a clamping mechanism for steel pipe cutting. Background Art

[0002] In the process of manufacturing steel pipes, a whole long steel pipe needs to be cut into multiple short steel pipes of required lengths. When cutting, multiple steel pipes are placed in two holding mechanisms so that the part of the steel pipe to be cut is located between the two clamps. After the steel pipe is clamped and fixed, the cutting mechanism cuts the steel pipe, and then the cut finished product is removed from the clamping mechanism. After that, the remaining part is transported forward and placed in the two clamping mechanisms. Therefore, each cutting must be transported forward, and the steel pipe is relatively heavy, so the work intensity is relatively high. Utility Model Content

Fixed connection, mounting seat 2 6 is close to the aisle, and mounting seat 3 7 is provided on the other side of the aisle. Mounting seat 3 7 is slidably connected to the upper part of the workbench 1. The upper part of the workbench 1 is fixedly connected with a connecting plate 2 8. The connecting plate 2 8 is close to the mounting seat 3. The connecting plate 2 8 is fixedly connected to a horizontal cylinder 2 9. Two guide rods 10 are fixedly connected between the connecting plate 2 8 and the mounting seat 2 6. The two guide rods 10 pass through the upper part of the aisle of the workbench 1, and the two guide rods 10 pass through the mounting seat 3 7. The mounting seat 3 7 is slidably connected to the guide rod 10, and the air cylinder 2 9 is fixedly connected to the connecting plate 2 8. The output shaft of cylinder 2 9 is fixedly connected to mounting seat 3 7, and mounting rod 15 is passed through connecting plate 2 8 and is slidably connected to it. Two nuts are threaded on the mounting rod 15, and the nuts are respectively located on both sides of connecting plate 2 8. The end of mounting rod 15 is fixedly connected with rubber terminal 16, and rubber terminal 16 contacts mounting seat 3 7. One side of mounting seat 1 5, mounting seat 2 6 and mounting seat 3 7 is respectively fixedly connected with horizontal cylinder 11. A protective cover is provided on the outside of cylinder 11, and the protective cover is fixedly connected to the mounting seat. Two clamping blocks 12 are respectively slidably connected to the upper part of the three mounting seats. The clamping blocks 12 are provided with V-shaped grooves, and a row of triangular teeth are integrally formed on both sides of the V-shaped groove of the clamping blocks 12. The triangular teeth of the two clamping blocks 12 on the same mounting plate mesh with each other.

The lead screw 4 rotates its slider to drive the mounting seat 1 5 to move along the remaining steel pipe, away from the mounting seat 2 6. The mounting seat 1 5 moves to the rear of the steel pipe and clamps it. The lead screw 4 rotates in the opposite direction, and the mounting seat 1 5 drives the steel pipe to move close to the mounting seat 2 6 and places the steel pipe on the mounting plate 3. After clamping the steel pipe, the cutting mechanism 2 cuts it again, thereby reducing the labor intensity of the workers.
