Abstract
Description
Technical Field
[0001] This invention relates to the field of machine tool technology, and in particular to a water pipe processing equipment. Background Technology
[0002] During the production or cleaning and maintenance of water pipes, it is often necessary to process or clean the inner wall of the pipes. When the inner wall of the water pipe is short, it can be done directly by manual labor or mechanical equipment. However, when the water pipe is long, it is difficult to process or clean the inner wall manually or by mechanical equipment. In particular, long water pipes are prone to bending and deformation under the influence of gravity, reducing the coaxiality of the pipe itself. This makes it even more difficult to process the inner wall. Since bending and deformation are unavoidable in water pipes, processing the inner wall can easily lead to damage from the inside out. Therefore, there is an urgent need for equipment that can improve the quality and stability of water pipe processing. Summary of the Invention
[0003] The purpose of this invention is to provide a water pipe processing device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.
[0004] According to a first aspect of the present invention, a water pipe processing device includes: a frame; a moving mechanism disposed on one side of the frame, the moving mechanism having a moving block movable toward or away from the other side of the frame; a processing mechanism including a positioning sleeve, an elastic element, a sliding element, a rotary drive element, a transmission sleeve, and a processing component, the positioning sleeve being sleeved on the outside of the moving block, the elastic element being disposed between the outside of the moving block and the inside of the positioning sleeve, a plurality of elastic elements being disposed around the moving block, a plurality of sliding elements being disposed around the outside of the positioning sleeve, the rotary drive element being disposed on the positioning sleeve, the transmission sleeve being rotatably connected to one end of the positioning sleeve, the rotary drive element being drively connected to the transmission sleeve, the rotary drive element being able to drive the transmission sleeve to rotate, and the processing component being disposed on the outer periphery of the transmission sleeve; and a pipe clamping mechanism disposed on the other side of the frame, the pipe clamping mechanism having an openable and closable pipe clamping space.
[0005] This technical solution has at least the following beneficial effects: The clamping space within the clamping mechanism is opened, and then the water pipe to be processed is placed into the clamping space and clamped. The moving block within the moving mechanism moves into the water pipe, driving the processing mechanism into the water pipe. At this time, the transmission sleeve within the processing mechanism first enters the water pipe. The transmission sleeve can rotate under the drive of the rotary drive component, using the processing component on the outside of the transmission sleeve to process the inner wall of the water pipe. Then, the positioning sleeve also enters the water pipe. Multiple sliding components on the outside of the positioning sleeve abut against the inner wall of the water pipe, supporting the end of the water pipe away from the clamping mechanism, thereby providing support for both ends of the water pipe. As the moving block continues to move into the water pipe, the water pipe gradually bends downwards near the middle. When the moving block moves towards the bend, the elastic element between the positioning sleeve and the moving block allows the positioning sleeve to flexibly adjust its position radially, which in turn drives the transmission sleeve to adjust its position. This ensures that the positioning sleeve and the transmission sleeve remain coaxial with the water pipe, thus guaranteeing that even when the water pipe bends downwards, the transmission sleeve can adjust its position accordingly. This allows the outer peripheral processing parts to accurately process the inner wall of the water pipe, improving the quality and stability of the processing of the inner wall of the water pipe. This method is also applicable to longer water pipes, making it more versatile overall.
[0006] As a further improvement to the above technical solution, the moving mechanism includes a fixed frame, a drive motor, a screw, and a slide rod. The fixed frame is connected to one side of the frame, and the drive motor and slide rod are respectively connected to the fixed frame. The drive motor drives the screw, which rotates. The screw and slide rod are parallel to each other. The moving block is threadedly connected to the screw, and the slide rod passes through the moving block. The fixed frame is fixed to one side of the frame. When the moving block needs to be moved, the drive motor drives the screw to rotate. The moving block and the screw are threadedly connected, and the slide rod passes through the moving block to form a sliding fit with it. This allows the moving block to move axially back and forth inside the water pipe.
[0007] As a further improvement to the above technical solution, multiple sliding rods are evenly arranged around the screw. These multiple sliding rods are slidably connected to the moving block, which better maintains the parallelism between the moving block and the sliding rods and screw, improving the load-bearing capacity of the water pipe.
[0008] As a further improvement to the above technical solution, an annular positioning groove is formed inside the positioning sleeve, facing the moving block, and the outer side of the moving block extends into the annular positioning groove. Inserting the outer side of the moving block into the annular positioning groove allows the moving block and the positioning sleeve to be positioned relative to each other axially. The annular positioning groove provides space for the moving block and the positioning sleeve to move radially relative to each other, thus enabling the positioning sleeve to move synchronously when the moving block moves, improving the stability of the overall structure.
[0009] As a further improvement to the above technical solution, an annular groove is provided on the end face of the positioning sleeve near the clamping mechanism. One end of the transmission sleeve extends into the annular groove, and the transmission sleeve and the annular groove are connected to each other by a bearing. The rotational connection between one end of the transmission sleeve and the annular groove via the bearing reduces the load at the connection point between the rotating drive component and the transmission sleeve, thus improving the structural stability of the transmission sleeve.
[0010] As a further improvement to the above technical solution, the rotary drive component is connected to the end face of the positioning sleeve away from the pipe clamping mechanism. The rotary drive component is driven by a transmission shaft, which passes through the positioning sleeve and extends to the inside of the transmission sleeve. A gear is connected to the end of the transmission shaft, and a gear ring is connected to the inside of the transmission sleeve. The gear and the gear ring mesh with each other. Installing the rotary drive component on the end face of the positioning sleeve away from the pipe clamping mechanism reduces the possibility of debris and waste generated during the processing of the water pipe's inner wall interfering with the normal operation of the rotary drive component. The transmission shaft connected to the rotary drive component passes through the positioning sleeve and extends to the inside of the transmission sleeve, transmitting power through the gear ring and gear to drive the transmission sleeve to rotate.
[0011] As a further improvement to the above technical solution, at least two rotary driving components are evenly arranged on the end face of the positioning sleeve. The at least two rotary driving components, evenly distributed on the end face of the positioning sleeve, can provide driving force from different directions inside the transmission sleeve, thereby improving the stability of power transmission to the transmission sleeve and increasing the torque of the transmission sleeve's rotation, ensuring the processing effect of the workpiece on the inner wall of the water pipe.
[0012] As a further improvement to the above technical solution, the machining component is detachably connected to the outer periphery of the transmission sleeve. The machining component can be disassembled and assembled according to different processing needs, thus adapting to different processing requirements for the inner wall of the water pipe, such as brushing or milling the inner wall of the water pipe.
[0013] As a further improvement to the above technical solution, the pipe clamping mechanism includes a three-jaw chuck, within which the pipe clamping space is formed. The three-jaw chuck has multiple jaws that can move closer to or further away from each other. When the multiple jaws move closer to each other, the pipe clamping space can be closed to clamp the water pipe; when the multiple jaws move further away from each other, the pipe clamping space can be opened to release the water pipe.
[0014] As a further improvement to the above technical solution, the pipe clamping mechanism further includes a translation drive component. The translation drive component is driven to connect to a translation seat, which can move the translation seat closer to or away from the moving block. The three-jaw chuck is connected to the moving block. The translation drive component can move the translation seat closer to or away from the processing mechanism on the frame, thereby adjusting the position of the water pipe. This allows the three-jaw chuck to move the water pipe closer to or away from the processing mechanism. For example, when the water pipe is short or needs to be moved closer to the processing mechanism during processing, the translation seat can be moved closer to the processing mechanism; when the water pipe is short or needs to be moved away from the processing mechanism during processing, the translation seat can be moved away from the processing mechanism.

[0021] Reference Figure 1 and Figure 2 According to a first aspect of the present invention, a water pipe processing device includes: a frame 1; a moving mechanism disposed on one side of the frame 1, the moving mechanism having a moving block 21 movable toward or away from the other side of the frame 1; and a processing mechanism including a positioning sleeve 31, an elastic element 32, a sliding element 33, a rotary drive element 34, a transmission sleeve 35, and a processing element 36, wherein the positioning sleeve 31 is sleeved on the outside of the moving block 21, the elastic element 32 is disposed between the outside of the moving block 21 and the inside of the positioning sleeve 31, and the elastic element 32 may be a spring, a torsion spring, or a rubber structure, the elastic element 32 surrounding the frame 1. Multiple movable blocks 21 are provided. Multiple sliding members 33 are arranged around the outer side of the positioning sleeve 31. The sliding members 33 can be balls or rollers, etc. The rotary drive member 34 is arranged on the positioning sleeve 31. The transmission sleeve 35 is rotatably connected to one end of the positioning sleeve 31. The rotary drive member 34 is connected to the transmission sleeve 35. The rotary drive member 34 can drive the transmission sleeve 35 to rotate. The outer periphery of the transmission sleeve 35 is provided with the processing part 36. The processing part 36 can be a cutting tool, brush, etc. The tube clamping mechanism is arranged on the other side of the frame 1. The tube clamping mechanism has an openable and closable tube clamping space.
[0022] In this water pipe processing equipment, when it is necessary to open the clamping space within the clamping mechanism, the water pipe to be processed is placed into the clamping space and clamped. The moving block 21 in the moving mechanism moves into the water pipe, driving the processing mechanism into the water pipe. At this time, the transmission sleeve 35 in the processing mechanism first enters the water pipe. The transmission sleeve 35 can rotate under the drive of the rotary drive 34. The processing part 36 on the outside of the transmission sleeve 35 processes the inner wall of the water pipe. Then, the positioning sleeve 31 also enters the water pipe. The multiple sliding parts 33 on the outside of the positioning sleeve 31 abut against the inner wall of the water pipe, supporting the end of the water pipe away from the clamping mechanism, thereby providing support for both ends of the water pipe. As the moving block... 21 continues to move into the water pipe. As the water pipe gradually bends downward near the middle, the elastic element 32 between the positioning sleeve 31 and the moving block 21 allows the positioning sleeve 31 to flexibly adjust its position radially and drive the transmission sleeve 35 to adjust its position. This ensures that the positioning sleeve 31 and the transmission sleeve 35 remain coaxial with the water pipe, thus ensuring that even if the water pipe bends downward, the transmission sleeve 35 can adjust its position accordingly. This allows the outer processing part 36 to accurately process the inner wall of the water pipe, thereby improving the quality and stability of the processing of the inner wall of the water pipe. This method is also applicable to longer water pipes and has greater overall versatility.
[0023] The moving mechanism has a drive source that can drive the moving block 21 to reciprocate. When the water pipe is long, the moving block 21 needs to move a large distance. In order to facilitate the moving block 21 to move a long distance, in this embodiment, the moving mechanism includes a fixed frame 22, a drive motor 23, a screw 24 and a slide bar 25. The fixed frame 22 is connected to one side of the frame 1. The drive motor 23 and the slide bar 25 are respectively connected to the fixed frame 22. The drive motor 23 drives the screw 24 and can drive the screw 24 to rotate. The screw 24 and the slide bar 25 are parallel to each other. The moving block 21 is threaded to the screw 24 and the slide bar 25 passes through the moving block 21. The fixed frame 22 is fixed to one side of the frame 1. When it is necessary to move the moving block 21, the drive motor 23 drives the screw 24 to rotate. The moving block 21 and the screw 24 are connected to the moving block 21 by threads, and the slide rod 25 passes through the moving block 21 and forms a sliding fit connection with the moving block 21. In this way, the moving block 21 can be driven to move back and forth axially in the water pipe.
[0024] Furthermore, multiple slide rods 25 are evenly arranged around the screw 24. These slide rods 25 are slidably connected to the moving block 21, which better maintains the moving block 21 parallel to the slide rods 25 and the screw 24, improving the load-bearing capacity of the water pipe.
[0025] The positioning sleeve 31 and the movable block 21 can be connected solely by the elastic element 32. When the movable block 21 moves, the positioning sleeve 31 moves via the elastic element 32. However, this would reduce the structural stability between the positioning sleeve 31 and the movable block 21. Therefore, in this embodiment, an annular positioning groove 311 is formed inside the positioning sleeve 31, facing the movable block 21. The outer side of the movable block 21 extends into the annular positioning groove 311. Inserting the outer side of the movable block 21 into the annular positioning groove 311 allows the movable block 21 and the positioning sleeve 31 to be positioned relative to each other axially. The annular positioning groove 311 provides space for the movable block 21 and the positioning sleeve 31 to move relative to each other radially. Thus, when the movable block 21 moves, it can drive the positioning sleeve 31 to move synchronously, improving the overall structural stability.
[0026] To improve the rotational stability of the positioning sleeve 31, in this embodiment, an annular groove is provided on the end face of the positioning sleeve 31 near the clamping mechanism. One end of the transmission sleeve 35 extends into the annular groove, and the transmission sleeve 35 and the annular groove are connected to each other by a bearing. The rotational connection between one end of the transmission sleeve 35 and the annular groove via the bearing reduces the load at the connection point between the rotary drive component 34 and the transmission sleeve 35, thereby improving the structural stability of the transmission sleeve 35.
[0027] The rotary drive 34 can be a drive source such as a motor, used to provide rotational driving force to the positioning sleeve 31. It can be installed on the same side of the positioning sleeve 31 as the transmission sleeve 35. In this embodiment, the rotary drive 34 is connected to the end face of the positioning sleeve 31 away from the clamping mechanism. The rotary drive 34 is driven by a transmission shaft 341. The transmission shaft 341 passes through the positioning sleeve 31 and extends to the inside of the transmission sleeve 35. A gear 342 is connected to the end of the transmission shaft 341. A gear ring 343 is connected to the inside of the transmission sleeve 35. The gear 342 and the gear ring 343 mesh with each other. The rotary drive 34 is installed on the end face of the positioning sleeve 31 away from the pipe clamping mechanism, which can reduce the possibility that the debris generated by the processing part 36 on the inner wall of the water pipe will interfere with the normal operation of the rotary drive 34. The transmission shaft 341 connected to the rotary drive 34 passes through the positioning sleeve 31 and extends to the inner side of the transmission sleeve 35. Power is transmitted through the gear ring 343 and the gear 342, thereby driving the transmission sleeve 35 to rotate.
[0028] Furthermore, at least two rotary drive members 34 are evenly arranged on the end face of the positioning sleeve 31. The at least two rotary drive members 34 are evenly arranged on the end face of the positioning sleeve 31, which can provide driving force from different directions inside the transmission sleeve 35, thereby improving the stability of power transmission to the transmission sleeve 35 and increasing the torque of the transmission sleeve 35 rotation, ensuring the processing effect of the workpiece 36 on the inner wall of the water pipe.
[0029] In some embodiments, the machining component 36 is detachably connected to the outer periphery of the transmission sleeve 35. The machining component 36 can be disassembled and assembled according to different processing needs, thus adapting to different processing requirements of the inner wall of the water pipe, such as brushing or milling the inner wall of the water pipe.
[0030] The pipe clamping mechanism includes structural components for clamping the water pipe. Specifically, the pipe clamping mechanism includes a three-jaw chuck 41, within which a pipe clamping space is formed. The three-jaw chuck 41 has multiple jaws that can move closer or further apart. When the jaws move closer together, the pipe clamping space is closed, clamping the water pipe. When the jaws move further apart, the pipe clamping space is opened, releasing the water pipe.
[0031] When the length of the water pipe changes, the position of the clamping mechanism can be adjusted. Therefore, in this embodiment, the clamping mechanism also includes a translation drive 42, which is connected to a translation seat. The translation drive 42 can move the translation seat closer to or away from the moving block 21. The three-jaw chuck is connected to the moving block 21. The translation drive 42 can be an electric screw, a cylinder, or a hydraulic cylinder. The translation drive 42 can move the translation seat closer to or away from the processing mechanism on the frame 1, thereby adjusting the position of the water pipe. This allows the three-jaw chuck to move the water pipe closer to or away from the processing mechanism. For example, when the water pipe is short or needs to be moved closer to the processing mechanism during processing, the translation seat can be moved closer to the processing mechanism. When the water pipe is short or needs to be moved away from the processing mechanism during processing, the translation seat can be moved away from the processing mechanism.
[0032] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described.
