They are widely used in heat exchange equipment, such as shell and tube heat exchangers, coil heat exchangers, serpentine tube heat exchangers, condensers, evaporators, and conveying pipelines. Nickel-titanium tubes need to be polished during processing, which requires the use of polishing equipment.

[0003] Existing polishing equipment for nickel-titanium tube processing has certain drawbacks. It lacks a cleaning structure, and the debris generated during the polishing process easily adheres to the surface of the nickel-titanium tube, affecting the polishing quality. Furthermore, the debris is scattered everywhere and is not easy to clean, which affects subsequent processing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fine polishing device for nickel-titanium tube processing with a cleaning structure, which has the advantage of being able to clean dust and solves the problem mentioned in the background technology of not being able to clean dust during fine polishing of nickel-titanium tubes.

[0005] To achieve the aforementioned purpose of cleaning dust during the fine polishing of nickel-titanium tubes, this utility model provides the following technical solution: It includes a worktable and two sliding grooves on either side of the worktable. A U-shaped plate is slidably connected inside the sliding groove. Connecting plates are fixedly connected to the bottom sides of the U-shaped plate. A cleaning plate is fixedly connected to the bottom of the connecting plates. The cleaning plate has beveled angles on both sides between the two connecting plates. A dust cover is installed at the bottom of the U-shaped plate between the two connecting plates. Mounting blocks are fixedly connected to both sides of the dust cover. Two sliding grooves are formed through the inner wall of one mounting block. Limiting grooves are formed in the middle of the two sliding grooves. Slider blocks are slidably connected to the inner cavities of the two sliding grooves. Limiting blocks are fixedly connected to both sides of the two sliders, and the limiting blocks slide within the limiting grooves. Cleaning rings are fixedly connected to the bottom of the two sliders. Two cylinders are fixedly connected to the relatively distant sides of the inner cavities of the two sliding grooves, and the cylinders penetrate the sliders. Springs are fitted on the outer walls of the four cylinders, and one end of the spring is fixedly connected to the slider.

[0006] As a further embodiment of this utility model: both sides of the inner cavity of the dust cover are rotatably connected to output rods, and a grinding disc is installed in the middle of the outer wall of each of the two output rods. A synchronous wheel is fixedly connected to the outer wall of the two output rods away from the grinding disc. A synchronous belt is sleeved on the outer wall of the synchronous wheel. A motor is fixedly connected to the outer wall of the dust cover, and the output end of the motor passes through the dust cover and is fixedly connected to the mounting block.

[0007] As a further embodiment of this utility model: a second motor is installed on one side of the outer wall of the workbench. The output end of the second motor passes through the workbench and is fixedly connected to an output rod. A turntable is fixedly connected to the end of the output rod away from the workbench, and the turntable passes through the workbench. Two guide grooves are opened through the outer wall of the turntable. Guide rods are slidably connected inside the two guide grooves.

A slider 11 is slidably connected to the inner cavity of the two sliding grooves 9. A limiting block 12 is fixedly connected to both sides of the two sliders 11, and the limiting block 12 slides in the limiting groove 10. A cleaning ring 1 is fixedly connected to the bottom of the two sliders 11. 3. Two cylinders 14 are fixedly connected to the relatively far sides of the inner cavities of the two slide grooves 2 and 9, and the cylinders 14 penetrate the slider 11. Springs 15 are sleeved on the outer walls of the four cylinders 14, and one end of the springs 15 is fixedly connected to the slider 11. The motor 21 is turned on to rotate, which drives the nickel-titanium tube to rotate and polish the nickel-titanium tube in all directions. During polishing, the lead screw motor 28 is turned on to drive the U-shaped plate 3 to slide in the slide groove 1 2. When the U-shaped plate 3 slides, it can drive the cleaning ring 13 to move. Through the contact between the cleaning ring 13 and the nickel-titanium tube, the surface of the nickel-titanium tube that is attached during polishing can be cleaned. When the U-shaped plate 3 moves, it drives the cleaning plate 5 to move and push the debris that falls on the surface of the worktable 1 during polishing to the material feeding groove 29, and then fall into the collection box 30 for unified collection.

[0023] A lead screw motor 28 is installed on the outer wall of the workbench 1 on the side away from the motor 21, and the lead screw part of the lead screw motor 28 passes through the U-shaped plate 3 and is threadedly connected.

[0024] The inner walls of the workbench 1 are provided with material discharge troughs 29 on both sides, and the material discharge troughs 29 cooperate with the cleaning plate 5. The bottom of the workbench 1 is equipped with a collection box 30, and the collection box 30 cooperates with the material discharge troughs 29.

[0025] Please see Figures 1-5 Both sides of the inner cavity of the dust cover 7 are rotatably connected to output rods 18. Grinding discs 19 are installed in the middle of the outer wall of each output rod 18. Synchronous pulleys 17 are fixedly connected to the outer wall of the two output rods 18 away from the grinding discs 19.

The output end of motor 16 passes through the dust cover 7 and is fixedly connected to the mounting block 8. When motor 16 is turned on, it drives the two grinding discs 19 to work through the synchronous pulleys 17 and the synchronous belts 20.

[0026] A motor 21 is installed on one side of the outer wall of the workbench 1. The output end of the motor 21 passes through the workbench 1 and is fixedly connected to an output rod 22. A turntable 23 is fixedly connected to the end of the output rod 22 away from the workbench 1, and the turntable 23 passes through the workbench 1. Two guide grooves 24 are formed through the outer wall of the turntable 23. Guide rods 25 are slidably connected inside the two guide grooves 24. A clamping ring 27 is fixedly connected to the side of the guide rod 25 away from the workbench 1. A clamping ring 27 is fixedly connected to the side of the guide rod 25 away from the clamping ring 27. There is a circular limiting block 26, which slides inside the worktable 1. When the motor 21 is turned on, the output rod 22 drives the turntable 23 to rotate. When the turntable 23 rotates, the guide rod 25 slides in the guide groove 24, causing the two clamping rings 27 to move closer to each other and clamp the guide rod 25 placed in the clamping ring 27. At the same time, the clamping ring 27 can rotate, causing the nickel-titanium tube inside the clamping ring 27 to rotate. A placement groove 31 is opened on one side of the top of the worktable 1, and the cleaning ring 13 is attached to the surface of the nickel-titanium tube.

[0027] The working principle of this utility model is as follows: When working, the nickel-titanium tube is first inserted into the placement groove 31, and then the nickel-titanium tube is passed between the two cleaning rings 13. The spring force of the spring 15 causes the slider 11 to slide in the second groove 9, so that the cleaning ring 13 fits against the surface of the nickel-titanium tube. Finally, it is placed between the two clamping rings 27. The motor 21 is turned on so that the output rod 22 drives the turntable 23 to rotate. When the turntable 23 rotates, the guide rod 25 slides in the guide groove 24, so that the two clamping rings 27 move closer to each other and clamp the guide rod 25 placed in the clamping ring 27. At the same time, the clamping ring 27 can rotate, which drives the nickel-titanium tube in the clamping ring 27 to rotate.

[0028] After the nickel-titanium tube is placed and clamped, motor 16 is turned on, which drives the two polishing discs 19 through synchronous pulley 17 and synchronous belt 20 to polish the placed nickel-titanium tube. At the same time, motor 21 is turned on to rotate, which drives the nickel-titanium tube to rotate and polish the nickel-titanium tube from all directions. During polishing, the lead screw motor 28 is turned on, which drives the U-shaped plate 3 to slide in the slide groove 2. When the U-shaped plate 3 slides, it can drive the cleaning ring 13 to move. By the contact between the cleaning ring 13 and the nickel-titanium tube, the surface of the nickel-titanium tube that is attached during polishing can be cleaned. At the same time as the U-shaped plate 3 moves, it drives the cleaning plate 5 to move and push the debris that falls on the surface of the worktable 1 during polishing into the feeding groove 29 and then into the collection box 30 for unified collection.
