Description

Technical Field

[0001] This utility model relates to the field of copper tube polishing technology, specifically to a magnetically controlled copper tube inner wall polishing device. Background Technology

[0002] In modern industrial production, copper tubing is widely used in numerous industries such as refrigeration, aerospace, and electronics. In these applications, the quality of the inner wall of the copper tubing plays a crucial role in the system's performance.

[0003] Traditional methods of polishing the inner walls of copper tubes mostly rely on manual operation. Hand-held polishing tools are used to grind the inner walls of the copper tubes. Firstly, manual polishing is extremely labor-intensive, requiring workers to maintain a specific posture for extended periods and perform repetitive operations in a confined space, easily leading to physical fatigue and very low work efficiency. Secondly, the precision and consistency of manual polishing are difficult to guarantee. Different workers have different operating techniques, pressure, and experience, and even the same worker cannot maintain completely consistent polishing results over long periods. This results in uneven surface precision of the copper tube's inner wall, which can easily lead to problems such as excessive local resistance or stress concentration during subsequent use, affecting the overall performance and lifespan of the equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a magnetically controlled copper tube inner wall polishing device, which solves the problems of low efficiency and inconsistent polishing results of manual polishing mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetically controlled copper tube inner wall polishing device, comprising an operating table, a telescopic pump rod mounted on the operating table, a connecting shaft connected to the output end of the telescopic pump rod, a polishing assembly mounted on the connecting shaft, the polishing assembly including a rotating shaft, the rotating shaft rotatably mounted on the connecting shaft, a polishing plate connected to the rotating shaft, a toothed ring surrounding one end of the rotating shaft, the toothed ring meshing with a gear, the gear being connected to the output end of a first motor, the first motor being fixedly mounted on the connecting shaft, and a fixing assembly mounted on the operating table.

[0006] Preferably, the fixing assembly includes a slide rod, which is vertically fixed on the operating table. Two sets of movable plates are slidably arranged on the slide rod. The two movable plates are respectively connected to the threads at both ends of the bidirectional threaded rod. One end of the bidirectional threaded rod is connected to the output end of the second motor. A V-shaped frame is installed on one side of each of the two sets of movable plates, and an anti-slip pad is installed on the V-shaped frame.

[0007] Preferably, the midpoint of the distance between the two V-shaped brackets corresponds to the axis of the connecting shaft.

[0008] Preferably, a fixing ring is fixedly installed on both ends of the rotating shaft, the fixing rings are connected to each other by a guide rod, a movable frame is slidably arranged on the guide rod, a rotating arm is arranged on the periphery of the movable frame and the periphery of the fixing ring at the front end of the rotating shaft, and mutually symmetrical connecting rods are rotatably installed on the movable frame and the rotating arm of the fixing ring, and the connecting rods are rotatably connected to the connecting frame at the bottom of the polishing plate.

[0009] Preferably, a connecting block is provided on the fixed ring at the rear end of the rotating shaft, and a spiral rod is spirally connected to the connecting block, the spiral rod being rotatably connected to the moving frame.

[0010] Preferably, the screw rod is provided with a limiting groove.

[0011] Preferably, a limiting rod is provided through the connecting block, and a pull handle is fixedly connected to one end of the limiting rod. The pull handle is connected to the connecting block by a spring, and the limiting rod corresponds to the limiting groove.

[0012] This invention provides a device for polishing the inner wall of a copper tube using magnetic control. It has the following advantages:

[0013] (1) This utility model uses a telescopic pump rod to push the connecting shaft and the polishing assembly on the connecting shaft to move inside the copper tube. Then, the first motor drives the gear to rotate the gear ring, so that the polishing plate on the rotating shaft polishes the inner wall of the copper tube. This avoids the problem of uneven precision caused by differences in manual operation techniques, force and experience, and ensures that the surface precision of the inner wall of the copper tube is uniform.

[0014] (2) This utility model utilizes the movable plate in the fixed component that is threadedly connected to both ends of the bidirectional threaded rod. By rotating the bidirectional threaded rod, the two sets of movable plates can slide relative to or opposite to each other on the slide rod, thereby driving the V-shaped frame to move and adjusting the distance between the two V-shaped frames to adapt to the outer diameter of copper tubes of different diameters and achieve stable clamping.

[0015] (3) This utility model pushes the movable frame to slide on the guide rod. When the movable frame slides, the polishing plate is driven to rotate around the connecting frame by the rotating arm and the connecting rod, changing the radial distance between the polishing plate and the rotating shaft to adapt to the inner wall of copper tubes of different diameters, so as to achieve polishing of the inner wall of copper tubes of different diameters.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] Please see Figures 1-5 This utility model provides a magnetically controlled copper tube inner wall polishing device, including an operating table 1, a telescopic pump rod 2 installed on the operating table 1, a connecting shaft 3 connected to the output end of the telescopic pump rod 2, a polishing assembly 4 installed on the connecting shaft 3, the polishing assembly 4 including a rotating shaft 41, the rotating shaft 41 being rotatably sleeved on the connecting shaft 3, a polishing plate 8 connected to the rotating shaft 41, a toothed ring 411 being arranged around one end of the rotating shaft 41, the toothed ring 411 meshing with a gear 43, the gear 43 being connected to the output end of a first motor 42, the first motor 42 being fixedly installed on the connecting shaft 3, and a fixing assembly 5 installed on the operating table 1;

[0029] The fixed assembly 5 includes a slide rod 51, which is vertically fixed on the operating table 1. Two sets of movable plates 54 are slidably arranged on the slide rod 51. The two movable plates 54 are respectively connected to the threads at both ends of the bidirectional threaded rod 52. One end of the bidirectional threaded rod 52 is connected to the output end of the second motor 53. A V-shaped frame 55 is installed on the corresponding side of the two sets of movable plates 54. Anti-slip pads 56 are installed on the V-shaped frame 55.

[0030] The midpoint of the distance between the two V-shaped brackets 55 corresponds to the axis of the connecting shaft 3.

[0031] Specifically, the second motor 53 is started, which drives the bidirectional threaded rod 52 to rotate. The movable plate 54, which is threadedly connected to both ends of the bidirectional threaded rod 52, slides relative to or away from each other on the slide rod 51. The movable plate 54 drives the V-shaped frame 55 to move, adjusting the distance between the two V-shaped frames 55, placing the copper tube on the V-shaped frame 55, and using the anti-slip pads 56 on the V-shaped frame 55 to firmly clamp the copper tube. Since the midpoint of the distance between the two V-shaped frames 55 corresponds to the axis of the connecting shaft 3, it ensures that the copper tube is in a suitable position after being fixed.

[0032] When the telescopic pump rod 2 is activated, its output end pushes the connecting shaft 3 and the polishing component 4 on the connecting shaft 3 into the copper tube. The first motor 42 is then turned on, and its output end drives the gear 43 to rotate. The gear ring 411, which meshes with the gear 43, rotates accordingly, thereby driving the rotating shaft 41 and the polishing plate 8 connected to the rotating shaft 41 to rotate at high speed. The high-speed rotating polishing plate 8 fully contacts and rubs against the inner wall of the copper tube, achieving polishing of the inner wall. The telescopic pump rod 2 can control the movement of the polishing component 4 inside the copper tube, thus enabling complete polishing of the inner wall of the copper tube.

[0033] The second motor 53, the telescopic pump rod 2, and the first motor 42 work together to replace manual hand tools for polishing. Workers no longer need to perform repetitive, high-intensity operations in a confined space for extended periods, greatly reducing labor intensity. At the same time, the first motor 42 stably drives the polishing plate 8 to rotate, avoiding inconsistent polishing results caused by differences in technique, force, and experience during manual operation. This ensures uniform polishing precision of the copper tube's inner wall, improves product quality, reduces subsequent malfunctions caused by inner wall quality issues, and extends the service life of the copper tube and related equipment.

[0034] Furthermore, for polishing copper tubes of different diameters, please refer to [link / reference needed]. Figures 1-5Fixed rings 44 are fixedly installed on both ends of the rotating shaft 41. The fixed rings 44 are connected to each other by a guide rod 45. A movable frame 46 is slidably arranged on the guide rod 45. A rotating arm 47 is provided on the periphery of the movable frame 46 and the periphery of the fixed ring 44 at the front end of the rotating shaft 41. Symmetrical connecting rods 48 are rotatably installed on the movable frame 46 and the rotating arm 47 of the fixed ring 44. The connecting rods 48 are rotatably connected to the connecting frame 81 at the bottom of the polishing plate 8.

[0035] A connecting block 441 is provided on the fixed ring 44 at the rear end of the rotating shaft 41. A screw rod 7 is screwed onto the connecting block 441. The screw rod 7 is rotatably connected to the movable frame 46.

[0036] A limiting groove 71 is provided on the screw rod 7;

[0037] A limiting rod 61 is provided through the connecting block 441. One end of the limiting rod 61 is fixedly connected to a pull handle 6. The pull handle 6 is connected to the connecting block 441 through a spring 62. The limiting rod 61 corresponds to the limiting groove 71.

[0038] Specifically, before placing the polishing assembly 4 into copper tubes of different diameters, the position of the polishing plate 8 needs to be adjusted according to the diameter of the copper tube. Pull the handle 6 outward, and the handle 6 will drive the limiting rod 61 to move outward against the elastic force of the spring 62, so that the limiting rod 61 can be disengaged from the limiting groove 71 of the spiral rod 7. At this time, the spiral rod 7 can rotate freely.

[0039] Rotating the screw rod 7 causes it to move axially during rotation, as it is helically connected to the connecting block 441. This movement causes the movable frame 46, which is rotatably connected to it, to slide on the guide rod 45. As the movable frame 46 slides, its circumferential rotating arm 47 drives the connecting rod 48 to rotate. The connecting rod 48 then drives the connecting frame 81, which is connected to the bottom of the polishing plate 8, to rotate. This causes the polishing plate 8 to rotate around the connecting frame 81, changing the radial distance between the polishing plate 8 and the rotating shaft 41. When the position is adjusted to a suitable level, i.e., when the polishing plate 8 is just flush with the inner wall of the copper tube to be polished, the rotation of the screw rod 7 is stopped.

[0040] Release the pull handle 6. Under the elastic force of the spring 62, the limit rod 61 is re-inserted into the limit groove 71 of the screw rod 7, restricting the rotation of the screw rod 7 and fixing the position of the moving frame 46 and the polishing plate 8. The adjusted polishing assembly 4 is placed into the copper tube through the telescopic pump rod 2. According to the normal polishing process, the first motor 42 drives the rotating shaft 41 to rotate, thereby driving the polishing plate 8 to polish the inner wall of the copper tube.

[0041] By precisely adjusting the radial distance between the polishing plate 8 and the rotating shaft 41, the polishing plate 8 can be tightly fitted to the inner wall of the copper tube, ensuring uniform and effective polishing during the polishing process of copper tubes of different diameters, thus improving the polishing quality and consistency. At the same time, by utilizing the cooperation between the limiting rod 61 and the limiting groove 71 and the elastic force of the spring 62, the positions of the spiral rod 7 and the moving frame 46 can be reliably fixed, ensuring that the position of the polishing plate 8 will not shift during the polishing process, thereby ensuring the stability and reliability of the polishing process.

[0042] Working principle: Start the second motor 53, the bidirectional threaded rod 52 rotates to make the moving plate 54 slide on the slide rod 51, drive the V-shaped frame 55 to adjust the spacing, place the copper tube on the V-shaped frame 55 and clamp it with the anti-slip pad 56, pull the handle 6 outward to make the limiting rod 61 disengage from the limiting groove 71, rotate the spiral rod 7 to drive the moving frame 46 to slide on the guide rod 45, change the radial distance between the polishing plate 8 and the rotating shaft 41 through the connecting rod 48, so that the polishing plate 8 fits against the inner wall of the copper tube, after adjustment, release the handle 6, so that the limiting rod 61 re-enters the limiting groove 71 and is fixed in position;

[0043] Start the telescopic pump rod 2, push the connecting shaft 3 and polishing assembly 4 into the copper tube, turn on the first motor 42, drive the gear 43 and gear ring 411 to rotate, so that the rotating shaft 41 and polishing plate 8 rotate at high speed. The telescopic pump rod 2 controls the movement of the polishing assembly 4 to complete the full polishing of the inner wall of the copper tube. After polishing is completed, the telescopic pump rod 2 retracts and withdraws the polishing assembly 4 from the copper tube.
