[0002] The cutting device for metal pipes is a device specifically used for cutting metal pipes. It can accurately cut pipes according to requirements, and is divided into manual, semi-automatic or full-automatic types. Through specific tools and control systems, it ensures cutting accuracy and efficiency, enabling the pipes to reach the expected size and shape, and is widely used in fields such as construction and manufacturing to meet various pipe processing requirements.

[0003] In the prior art, when obtaining a pipe fitting length suitable for processing, operations such as cutting and grinding are required for longer pipe fittings. Since most traditional clamping means only clamp the outer walls at both ends of the pipe fitting, this clamping method is not stable enough. At the same time, friction marks are easily caused on the surface of the pipe fitting during the cutting vibration, and additional grinding and polishing by the staff are required, increasing the workload of the staff.

[0015] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. The embodiments of the present utility model are given for the purpose of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0016] Embodiment: Please refer to Figure 1 - Figure 4 , the present utility model provides a technical solution: a metal pipe cutting and grinding device, comprising: a workbench 1; a cutting machine 3, the inner wall of the workbench 1 is fixedly connected with the cutting machine 3; a clamping device 4, the outer wall of the clamping device 4 is slidably connected with the outer wall of the workbench 1; a positioning device 5, the bottom of the positioning device 5 is fixedly connected with the bottom of the workbench 1; a threaded rod 6, the outer wall of the threaded rod 6 is rotatably connected with the inner wall of the workbench 1; a limiting rod 7, the outer wall of the limiting rod 7 is fixedly connected with the inner wall of the workbench 1; the clamping device 4 includes a slider 41, the inner wall of the slider 41 is threadedly connected with the threaded rod 6 through a threaded hole 42, and the threaded hole 42 is opened in the wall of the slider 41, the inner wall of the slider 41 is slidably connected with the limiting rod 7 through a limiting hole 43, and the limiting hole 43 is opened in the wall of the slider 41, the top of the slider 41 is fixedly connected with a fixed disk 44, the inner wall of the fixed disk 44 is slidably connected with a clamping rod 46 through a limiting groove 45, and the limiting groove 45 is opened in the wall of the fixed disk 44, the outer wall of the clamping rod 46 is rotatably connected with a rotating disk 47, the outer wall of the rotating disk 47 is slidably connected with the fixed disk 44 through a sliding groove 48, and the sliding groove 48 is opened in the wall of the rotating disk 47, the top of the slider 41 is fixedly connected with a fixing device 49, the outer wall of the slider 41 is slidably connected with the outer wall of the workbench 1, and a chip cleaning groove 2 is opened in the wall of the workbench 1.

[0017] The positioning device 5 includes a fixing block 51. The outer wall of the fixing block 51 is fixedly connected with a positioning cylinder 52. A fixing shaft 53 is slidably connected to the inner wall of the positioning cylinder 52. A dismounting block 55 is threadedly connected to the outer wall of the fixing shaft 53 through a thread groove 54, and the thread groove 54 is formed in the wall of the fixing shaft 53. The bottom of the fixing block 51 is fixedly connected to the top of the workbench 1. Before use, select a dismounting block 55 suitable for the inner diameter of the pipe fitting and install it on the fixing shaft 53 through the thread groove 54. The fixing shaft 53 is inserted into the positioning cylinder 52. During use, the metal pipe fitting to be cut is sent into the clamping device 4 on the workbench 1 and continuously pushed towards the positioning device 5. During this process, the inner diameter of the pipe fitting swallows the dismounting block 55, and due to the frictional effect, the dismounting block 55 and the fixing shaft 53 are driven to move. The end face of the pipe fitting finally abuts against the positioning cylinder 52 on the fixing block 51. At this time, loosen the rotating disk 47 fixed by the fixing device 49. When the rotating disk 47 moves along the sliding groove 48 on the fixed disk 44, it will drive the clamping rod 46 to move. The end of the clamping rod 46 away from the rotating disk 47 slides on the limiting groove 45 of the fixed disk 44. At the same time, the three clamping plates stably approach the pipe fitting and clamp the pipe fitting. When the clamping is completed, fix the position of the rotating disk 47 through the fixing device 49. At this time, slightly rotate the threaded rod 6. Due to the setting of the threaded hole 42 in the slider 41, control the axial position of the slider 41 along the limiting rod 7 under the limitation of the limiting hole 43. The pipe fitting clamped by the clamping device 4 and the positioning cylinder 52 move, and the pipe fitting is fixed stably by applying pressure.

[0018] The fixing device 49 includes a fixing plate 491. The outer wall of the fixing plate 491 is fixedly connected with a fixing cylinder 492. An insertion column 494 is slidably connected to the inner wall of the fixing cylinder 492. A compression spring 493 is fixedly connected to the outer wall of the insertion column 494. The end of the compression spring 493 away from the insertion column 494 is fixedly connected to the inner wall of the fixing cylinder 492. A pull rod 495 is slidably connected to the outer wall of the fixing cylinder 492. The outer wall of the pull rod 495 is fixedly connected to the outer wall of the insertion column 494. The outer wall of the insertion column 494 is slidably connected to the inner wall of the rotating disk 47. The bottom of the fixing plate 491 is fixedly connected to the top of the slider 41. When releasing the fixation, pull the pull rod 495 outwards. The pull rod 495 drives the insertion column 494 to move, so that the insertion column 494 withdraws from the circular hole-shaped recess of the rotating disk 47. At the same time, the insertion column 494 moves axially along the fixing cylinder 492 under the limitation of the fixing plate 491 and the fixing cylinder 492, and cooperates with the fixing cylinder 492 to squeeze the compression spring 493. When the clamping is stable, release the pulling force on the pull rod 495. The compressed compression spring 493 stretches to restore its original state. At this time, the pull rod 495 moves axially along the fixing cylinder 492 and drives the insertion column 494 into the rotating disk 47, thereby restricting the rotation of the rotating disk 47.

[0019] Working principle:

[0020] Before use, select a disassembly block 55 suitable for the inner diameter of the pipe fitting and install it on the fixed shaft 53 through the threaded groove 54. The fixed shaft 53 is inserted into the positioning cylinder 52. During use, the metal pipe fitting to be cut is fed into the clamping device 4 on the workbench 1 and continuously pushed towards the positioning device 5. During this process, the inner diameter of the pipe fitting swallows the disassembly block 55, and due to the frictional force, the disassembly block 55 and the fixed shaft 53 are driven to move. The end face of the pipe fitting finally abuts against the positioning cylinder 52 on the fixed block 51. At this time, loosen the rotating disk 47 fixed by the fixing device 49. When the rotating disk 47 moves along the sliding groove 48 on the fixed disk 44, it will drive the clamping rod 46 to move. The end of the clamping rod 46 away from the rotating disk 47 slides on the limiting groove 45 of the fixed disk 44. At the same time, the three clamping plates stably approach the pipe fitting and clamp the pipe fitting. When the clamping is completed, fix the position of the rotating disk 47 through the fixing device 49. At this time, slightly rotate the threaded rod 6. Due to the setting of the threaded hole 42 in the slider 41, control the slider 41 to move along the axial position of the limiting rod 7 under the restriction of the limiting hole 43. The pipe fitting clamped by the clamping device 4 and the positioning cylinder 52 move. By applying pressure, the pipe fitting is fixed stably. At this time, use the cutting machine 3 to cut the metal pipe fitting, which is convenient for subsequent workers to carry out the grinding work. The clamping device 4 set in the cutting and grinding device for metal pipe fittings ensures the stable fixation of the metal pipe fitting during the processing, effectively preventing the displacement and shaking of the metal pipe fitting, thereby ensuring the accuracy of the cutting process and the grinding process, reducing errors, and the stable clamping can also improve the safety of processing. At the same time, the cooperation of the clamping device 4 and the positioning device 5 helps to achieve continuous operation, without the need to frequently adjust the position of the metal pipe fitting, saving operation time, improving production efficiency, and being able to adapt to workpieces of different shapes and sizes, increasing the versatility of the device. At the same time, a chip clearing groove 2 is provided.

[0021] The setting of the fixing device 49 further increases the stability of the clamping device 4. When releasing the fixation, pull the pull rod 495 outwards. The pull rod 495 drives the insertion column 494 to move, so that the insertion column 494 withdraws from the circular hole-shaped depression of the rotating disk 47. At the same time, the insertion column 494 moves along the axial direction of the fixed cylinder 492 under the limitation of the fixed plate 491 and the fixed cylinder 492, and cooperates with the fixed cylinder 492 to squeeze the compression spring 493. When the clamping is stable, release the pulling force on the pull rod 495. The compressed compression spring 493 stretches to restore its original state. At this time, the pull rod 495 moves along the axial direction of the fixed cylinder 492 and drives the insertion column 494 into the rotating disk 47, thereby restricting the rotation of the rotating disk 47. At this time, the clamping of the pipe fitting is completed, preventing the clamping device 4 from clamping unstably and further increasing the stability of the clamping device 4.

[0022] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art and related fields based on the embodiments in the present utility model without creative efforts shall fall within the scope of protection of the present utility model.
