Technical Field
[0001] This utility model belongs to the field of copper tube processing technology, and in particular relates to a deburring device for processing copper tube ends. Background Technology
[0002] Copper tubing is a crucial component in refrigeration systems, commonly used to transfer refrigerant and heat to ensure proper system operation. Copper's strong corrosion resistance, high strength, flexibility, and long lifespan make copper tubing an essential part of refrigeration systems. However, copper tubing is typically produced in coils; processing it into refrigeration tubing requires straightening, cutting, grinding, and welding. The deburring process still presents the following drawbacks: First, the copper tubes are cut to the specified length. At this time, burrs will be generated at the cut ends of the copper tubes. These burrs need to be removed by grinding and other processes to facilitate subsequent connection, welding and other operations. However, different refrigeration equipment requires copper tubes of different sizes. This means that the relevant deburring and grinding equipment cannot meet the deburring needs of copper tubes with different inner diameters. Manual grinding is even slower and not recommended. Secondly, the copper pipes of different refrigeration equipment will have different sizes and different wall thicknesses, so it is necessary to polish the copper pipes to meet the different wall thicknesses. As for the deburring and polishing process of copper pipe ends, there are two aspects: first, polishing to remove burrs from the end face of the end, and second, polishing burrs from the inner and outer edges of the end face of the end. Otherwise, the removal of burrs will still be incomplete. Conventional polishing structures are flat, making it difficult to effectively polish the edges, and improvements are still needed. Utility Model Content
[0003] The purpose of this utility model is to provide a deburring device for processing copper pipe ends. By setting up a geared motor, turntable, main grinding block, screw, adjusting block, upper grinding block, lower grinding block, and bolts, it solves the problems that the same deburring device is difficult to use for deburring copper pipes with different inner diameters, cannot meet the requirements for deburring copper pipes with different wall thicknesses, and is difficult to clean the burrs on the inner and outer edges of the copper pipe ends.
[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a deburring device for processing copper pipe ends, including a worktable, a geared motor, a turntable, clamping components and a main grinding block. The worktable has two working surfaces, a high one and a low one, on its upper surface. A geared motor is fixed on the high working surface of the worktable. The output shaft of the geared motor faces upwards from the low working surface and is fixed to the turntable. Two clamping components are arranged symmetrically on the low working surface of the worktable. The turntable has an adjustment groove on the side away from the geared motor. A screw is rotatably connected in the adjustment groove, and an adjustment block is threadedly connected to the outer circumference of the screw in the adjustment groove. The main grinding block is fixed on the side of the adjusting block near the opening of the adjusting groove. An upper grinding block and a lower grinding block are movably arranged on the side of the main grinding block away from the adjusting block. An L-shaped rod is fixed on the opposite side of the upper grinding block and the lower grinding block. Bolts are rotatably connected to the upper and lower ends of the main grinding block. A threaded ring is fixed to one end of the horizontal part of the L-shaped rod, and the threaded ring is threaded around the bolt close to it.
[0005] Furthermore, support legs are fixed at the four corners of the bottom of the workbench, and two clamping motors are fixed on the bottom surface of the workbench. Two adjusting rods are rotatably connected to the low working surface of the workbench, and two symmetrical limiting rods are fixed on the workbench outside each adjusting rod.
[0006] Furthermore, the adjusting rod is provided with two sections of threads with opposite directions, and a clamping motor is provided on the bottom surface of the worktable under each adjusting rod. The output shaft of the clamping motor passes through the worktable and is fixedly connected to the bottom end of the adjusting rod above it.
[0007] Furthermore, each of the clamping components includes two arc-shaped clamping plates, the inner arc surface of which is in contact with the outer circumferential surface of the copper tube to be processed, and end plates are fixed on both sides of each clamping plate, with a connecting plate fixed between the two end plates on the same side of the two clamping plates.
[0008] Furthermore, the middle portions of the two connecting plates in the upper clamping assembly are respectively threaded to the outer threads of the upper part of the two adjusting rods, and the middle portions of the two connecting plates in the lower clamping assembly are respectively threaded to the outer threads of the lower part of the two adjusting rods. The end plate is sleeved through the limiting rod adjacent to it.
[0009] Furthermore, the cross-sectional area of the adjusting groove is equal to the cross-sectional area of the adjusting block, and the upper end of the screw extends through the adjusting groove, out of the turntable, and is fixed with a handwheel.
[0010] Furthermore, the sides of the upper and lower grinding blocks facing each other, near the main grinding block, are both arc-shaped. Connecting rods are fixed on both sides of the upper and lower grinding blocks, and limiting protrusions are fixed on the facing sides of the two connecting rods extending out of the upper grinding block. Limiting grooves are opened on both sides of the main grinding block, and the limiting protrusions are slidably disposed in the limiting grooves.
[0011] This utility model has the following beneficial effects: This invention solves the problem that it is difficult for the same deburring device to deburr and grind copper tubes with different inner diameters by setting up a geared motor, turntable, main grinding block, screw, and adjusting block. By rotating the screw with a handwheel, the adjusting block is raised and lowered in the adjusting groove, thereby raising and lowering the main grinding block, changing the distance between the main grinding block and the center of the turntable, thus changing the radius of the deburring area to fit the corresponding copper tube radius. Subsequently, the geared motor drives the turntable to rotate, which in turn rotates the main grinding block and other components to perform deburring and grinding. The main grinding block grinds the end face of the copper tube end flat, while the upper and lower grinding blocks fit against the inner and outer edges of the copper tube end for synchronous grinding.
[0012] This invention solves the problem of not being able to deburr and grind copper tubes of different wall thicknesses by setting up an upper grinding block, a lower grinding block, and a bolt. By rotating the bolt, the L-shaped rod is moved closer to or further away from the center of the main grinding block, thereby controlling the distance between the upper and lower grinding blocks. The distance between the upper and lower grinding blocks is the wall thickness of the copper tube, which is used for corresponding adjustment.
[0013] This invention solves the problem of removing burrs from the inner and outer edges of copper pipe ports by setting up an upper grinding block and a lower grinding block. Both the upper and lower grinding blocks have curved surfaces on the side closest to the main grinding block. During grinding, the curved surface of the upper grinding block will form a rounded corner on the outer edge of the copper pipe port, and the curved surface of the lower grinding block will form a rounded corner on the inner edge of the copper pipe port, thus completely removing all burrs.
[0014] This invention features two symmetrical clamping components. When the clamping motor operates, it drives the adjusting rod to rotate. The adjusting rod has threads with opposite directions at both ends, and each thread corresponds to a clamping component. Therefore, the two clamping components will move closer or further apart to maintain a consistent center. This ensures that the central axis of the copper tube being clamped is aligned with the central axis of the turntable, preventing errors and guaranteeing the precision of deburring. This invention is highly practical. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0019] Please see Figure 1-8 As shown, this utility model is a deburring device for processing copper pipe ends, including a worktable 1, a reduction motor 2, a turntable 3, a clamping assembly 4 and a main grinding block 5. The worktable 1 has two working surfaces, a high one and a low one, on its upper surface. The reduction motor 2 is fixed on the high working surface of the worktable 1. The output shaft of the reduction motor 2 faces the upper part of the low working surface and is fixed on the turntable 3. Two clamping assemblies 4 are arranged symmetrically on the low working surface of the worktable 1. The geared motor 2 is used as the main deburring and polishing drive. The slightly higher setting allows the turntable 3 to have enough rotation space. The clamping assembly 4 is set on the low working surface of the worktable 1 to perform deburring and polishing on the copper tube to be processed. An adjustment groove 301 is provided on the side of the turntable 3 away from the geared motor 2. A screw 302 is rotatably connected in the adjustment groove 301, and an adjustment block 303 is threadedly connected to the outer circumference of the screw 302 in the adjustment groove 301. By rotating the screw 302, and in conjunction with the restriction of the adjusting block 303 within the adjusting groove 301, the adjusting block 303 can be raised or lowered, thereby controlling the displacement of the relevant structures on the adjusting block 303. A main grinding block 5 is fixed on the side of the adjusting block 303 that is close to the opening of the adjusting groove 301. An upper grinding block 501 and a lower grinding block 502 are movably arranged on the side of the main grinding block 5 that is away from the adjusting block 303. An L-shaped rod 503 is fixed on the opposite sides of the upper grinding block 501 and the lower grinding block 502. Bolts 504 are rotatably connected to the upper and lower ends of the main grinding block 5. A threaded ring 5031 is fixed on one end of the horizontal part of the L-shaped rod 503, and the threaded ring 5031 is threadedly sleeved on the outside of the bolt 504 that is close to it. The main grinding block 5 grinds the end face of the copper tube port flat, while the upper grinding block 501 and the lower grinding block 502 fit against the inner and outer edges of the copper tube port for synchronous grinding. By rotating the bolt 504, the threaded ring 5031 is raised and lowered, thereby raising and lowering the L-shaped rod 503 and the upper grinding block 501 or the lower grinding block 502 connected to it, changing the distance between the upper grinding block 501 and the lower grinding block 502, thus adapting to the grinding of copper tubes with different wall thicknesses.
[0020] Support legs 101 are fixed at the four corners of the bottom of the workbench 1. Two clamping motors 104 are also fixed on the bottom surface of the workbench 1. Two adjusting rods 102 are rotatably connected to the low working surface of the workbench 1. Two symmetrical limiting rods 103 are fixed on the workbench 1 outside each adjusting rod 102. The adjusting rod 102 is provided with two sections of threads with opposite directions, and a clamping motor 104 is provided on the bottom surface of the worktable 1 under each adjusting rod 102. The output shaft of the clamping motor 104 passes through the worktable 1 and is fixedly connected to the bottom end of the adjusting rod 102 above it. The worktable 1 is supported by the support leg 101 to make it a certain height off the ground. The adjusting rod 102 can be driven to rotate by the operation of the clamping motor 104. Each clamping assembly 4 includes two arc-shaped clamping plates 401. The inner arc surface of the clamping plate 401 is in contact with the outer circumference of the copper tube to be processed. Each clamping plate 401 has an end plate 402 fixed on both sides. A connecting plate 403 is fixed between the two end plates 402 on the same side of the two clamping plates 401. The middle portions of the two connecting plates 403 in the upper clamping assembly 4 are threaded to the upper threads of the two adjusting rods 102, and the middle portions of the two connecting plates 403 in the lower clamping assembly 4 are threaded to the lower threads of the two adjusting rods 102. The end plate 402 is sleeved through the limiting rod 103 that is close to it. When the adjusting rod 102 rotates, its two threaded sections at the top and bottom drive the connecting plates 403 in the two clamping assemblies 4 to move. Because the threads connecting the two clamping assemblies 4 are in opposite directions, the two clamping assemblies 4 move synchronously, moving closer or further away from each other, to stably clamp the copper tube between the two clamping assemblies 4 and keep the central axis of the copper tube and the central axis of the turntable 3 on the same straight line. Furthermore, due to the setting of the limiting rod 103, the end plate 402 is sleeved outside the limiting rod 103, so that the clamping assembly 4 will not rotate, but will only rise and fall.
[0021] The cross-sectional area of the adjusting groove 301 is equal to that of the adjusting block 303, and the upper end of the screw 302 extends through the adjusting groove 301, extends out of the turntable 3, and is fixed with a handwheel 3021; the screw 302 can be rotated by the handwheel 3021, so that the adjusting block 303 can be raised and lowered in the adjusting groove 301.
[0022] The sides of the upper grinding block 501 and the lower grinding block 502 that are close to the main grinding block 5 are both made of arc surface. Both sides of the upper grinding block 501 and the lower grinding block 502 are fixed with connecting rods 506. The two connecting rods 506 that extend out of the upper grinding block 501 are fixed with limiting protrusions 5061. Both sides of the main grinding block 5 are provided with limiting grooves 505, and the limiting protrusions 5061 are slidably disposed in the limiting grooves 505. When the turntable 3 rotates, the arc surface of the upper grinding block 501 grinds the outer edge of the copper tube port to form a rounded corner, and the arc surface of the lower grinding block 502 grinds the inner edge of the copper tube port to form a rounded corner, completely removing all burrs; and the connecting rod 506 slides into the limiting groove 505 through the limiting protrusion 5061 to ensure the stability of the upper grinding block 501 and the lower grinding block 502 when adjusting the distance.
[0023] The specific working principle of this utility model is as follows: First, the copper tube to be processed is placed between two clamping components 4. Due to the setting of the limiting rod 103, the end plate 402 is sleeved on the limiting rod 103, preventing the clamping components 4 from rotating. Then, the clamping motor 104 works, driving the adjusting rod 102 to rotate. The two threaded sections at its upper and lower parts drive the connecting plate 403 in the two clamping components 4 to move up and down, moving closer or further away from each other, to stably clamp the copper tube between the two clamping components 4 and keep the central axis of the copper tube and the central axis of the turntable 3 in the same straight line. Then, the screw 302 is rotated by the handwheel 3021, causing the adjusting block 303 to rise and fall in the adjusting groove 301, thereby raising and lowering the main grinding block 5, changing the distance between the main grinding block 5 and the center of the turntable 3, thereby increasing the radius of the deburring and grinding area. The adjustment is made to fit the corresponding copper pipe radius. Then, the bolt 504 is rotated to move the L-shaped rod 503 closer to or further away from the center of the main grinding block 5, thereby controlling the distance between the upper grinding block 501 and the lower grinding block 502. The upper grinding block 501 is pressed against the outer edge of the copper pipe port, and the lower grinding block 502 is pressed against the inner edge of the copper pipe port. The distance between the upper grinding block 501 and the lower grinding block 502 is the wall thickness of the copper pipe. After adjustment, the reduction motor 2 drives the turntable 3 to rotate, which in turn rotates the main grinding block 5, etc., to perform deburring and grinding. The main grinding block 5 grinds the end face of the copper pipe port flat. The arc surface of the upper grinding block 501 grinds the outer edge of the copper pipe port to form a rounded corner, and the arc surface of the lower grinding block 502 grinds the inner edge of the copper pipe port to form a rounded corner, completely removing all burrs.
[0024] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
