Description

Technical Field

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

[0002] Fixing the pipe is very important during the pipe processing process, which can ensure that the pipe maintains a stable position and angle during processing, and can bring many benefits such as accuracy, safety, efficiency and quality.

[0003] The prior art discloses a fixing device for pipe processing, with the application number CN202322596187.3. The principle is to adjust the distance between the two sets of pipe clamps and make them correspond to each other up and down by shaking the handle according to the length of the pipe. The first hydraulic cylinder drives the bracket to rotate to one side to place the pipe in the jaws of the lower pipe clamp, and the first hydraulic cylinder drives the bracket to reset; then the second hydraulic cylinder drives the lifting seat downward to stably clamp the pipe between the upper pipe clamp and the lower pipe clamp, and start the third hydraulic cylinder. The pressure block pushes the movable rod to move and engage with the rack, and compresses the spring to achieve the locking and fixation of the lifting seat and the upper pipe clamp, thereby avoiding the problem of loosening of the pipe clamp during pipe processing, thereby effectively improving the stability of pipe fixation.

[0004] However, when it is used, different sizes of pipes are fixed by replacing different clamps. This makes it impossible to continue to fix the steel pipe during the process of replacing the clamps, which not only affects the processing efficiency of the steel pipe, but also increases the labor intensity of the staff.

The clamp seat 5 is provided with a sealing device, and the inner wall of the clamp seat 5 is slidably connected with a partition plate 7, and the outer edge of the partition plate 7 is sealed with the inner wall of the clamp seat 5, and the end of the partition plate 7 away from the clamp rod 6 is fixedly connected with a spring 8, and the other end of the spring 8 abuts against the inner wall of the clamp seat 5, and the inner wall of the clamp seat 5 is fixedly connected with a symmetrically arranged blocking rod 9 for blocking the partition plate 7; the staff rotates the transmission rod 3 to make the clamp seat 5 bring the pipe closer, so that the clamp rod 6 clamps and fixes the pipe at multiple points, so that the pipe is not only evenly distributed in the process of fixing, which can reduce the possibility of deformation or damage of the pipe and improve the stability when fixing the pipe, but also suitable for pipes of different shapes and sizes, with good versatility and practicality, thereby reducing the labor intensity of workers when fixing the pipe and increasing the efficiency of pipe processing.

[0024] Furthermore, an active groove 10 is provided at one end of the clamp seat 5 away from the clamp rod 6 for passing through it, and a threaded rod 11 is fixedly connected to one end of the partition plate 7 away from the clamp rod 6, and the threaded rod 11 is sleeved inside by a spring 8, and the other end of the threaded rod 11 passes through the active groove 10 and extends to the outside of the clamp seat 5, and a locking nut 12 is threadedly connected to the threaded rod 11 extending to the outside of the clamp seat 5, and the locking nut 12 abuts against the end of the clamp seat 5 away from the clamp rod 6 under the pulling force of the threaded rod 11; by providing the locking nut 12, the clamp rod 6 can be locked after it is moved to clamp and fix the pipe once, so that when processing the same batch of pipes with the same size, the clamp rod 6 does not need to adjust its position multiple times, thereby increasing the efficiency of fixing the pipe and the service life of the clamp rod 6.

[0025] Furthermore, a symmetrically arranged support rod 13 is fixedly connected to the inner surface of the fixing seat 1, and an arc-shaped support plate 14 is fixedly connected to the other end of the support rod 13; after the pipe is directly supported by the support plate 14, the pipe is fixed by the clamping rod 6, which increases the convenience for the staff when placing the pipe in the fixing seat 1 for fixing.

[0026] Furthermore, one end of the clamp rod 6 away from the clamp seat 5 is hinged with an arc-shaped abutment plate 15 through a torsion spring; by setting the arc-shaped abutment plate 15, when the abutment plate 15 comes into contact with pipes of different sizes, the abutment plate 15 can be twisted so as to fit the inner wall of the pipe, thereby increasing the contact area for clamping and fixing the pipe when fixing the pipe, thereby increasing the fixing effect of the pipe.

[0028] Embodiment 2

[0029] like Figure 1 As shown, a motor 17 is fixedly connected to the top of the fixing seat 1, and the main shaft of the motor 17 passes through the fixing seat 1 and is fixedly connected to the end of the transmission rod 3; the transmission rod 3 is driven to rotate by the motor 17 to automatically fix the pipe;

[0030] Compared with the first embodiment, the rotation of the transmission rod 3 in this embodiment is driven by the motor 17, thereby reducing the labor intensity of the workers when fixing the pipes and the convenience of fixing the pipes, but increasing the production cost and the energy consumption of the driving motor 17 when fixing the pipes.

[0031] Working principle: This embodiment provides a pipe fixing device for pipe processing. When in use, the staff places the pipe to be fixed on the support plate 14, and the support rod 13 and the support plate 14 support the pipe. The rotation of the transmission rod 3 will drive the linkage rods 2 to approach each other through the threaded groove 4, so that the linkage rod 2 drives the clamping seat 5 to approach the pipe. As the clamping seat 5 moves, the clamping rod 6 on the clamping seat 5 will gradually drive the abutment plate 15 to contact the outer wall of the pipe, and start to move the clamping rod 6 toward the inside of the clamping seat 5. During the movement of the clamping rod 6, an arc distribution state that fits the pipe will gradually be formed between the ends away from the clamping seat 5, and the other end of the clamping rod 6 will push the hydraulic oil inside the clamping seat 5 during the movement into the inside of the clamping seat 5. The hydraulic oil cannot be compressed, so the hydraulic oil will push the partition plate 7 at this time, so that the partition plate 7 starts to squeeze the spring 8 to start moving, and after moving, it is blocked by the blocking rod 9 and cannot move. At this time, after the clamping rod 6 drives the abutment plate 15 to fit the outer wall of the pipe, the clamping rod 6 cannot move due to the hydraulic oil squeezing. At this time, the clamping rod 6 cannot move, and the abutment plate 15 fits the surface of the pipe at multiple points under the drive of the clamping rod 6. Therefore, as the transmission rod 3 continues to rotate, the clamping seat 5 continues to move, which makes the clamping rod 6 clamp and fix the pipe through the abutment plate 15, and then reverses through the transmission rod 3. Similarly, the spring 8 will drive the partition plate 7 to reset and move under its own elastic force, so that the clamping rod 6 and the abutment plate 15 can be reset to prepare for the next fixation of the pipe.

[0032] It should be noted that after the pipe is fixed, the locking nut 12 can be rotated to make the locking nut 12 abut against the end of the clamp seat 5 away from the clamp rod 6, so that the partition plate 7 cannot be reset and moved under the elastic force of the spring 8. Therefore, when processing the same batch of pipes of the same size, the clamp rod 6 does not need to adjust the position multiple times, thereby increasing the efficiency of fixing the pipe and the service life of the clamp rod 6.

[0033] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
