DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0026] Reference Figures 1 to 6 As shown, the utility model is a copper tube internal thread processing and positioning device, including a workbench 1, a fixed base 2 is fixedly connected to the top of the workbench 1, four pressure rods 3 are slidably connected to the top of the fixed base 2, a first motor 4 is fixedly connected to the bottom center of the workbench 1, a rotating shaft 5 is fixedly connected to the output end of the first motor 4, one end of the rotating shaft 5 is fixedly connected to a first gear 6, and the two ends of the first gear 6 are respectively meshed with a first rack 7, the rotating shaft 5 is located below the first gear 6 and is fixedly connected to a second gear 8, and the two ends of the second gear 8 are respectively meshed with a second rack 9 , one end of the first rack 7 and the second rack 9 extends to the top of the workbench 1 and is slidably connected to the workbench 1, and the two first racks 7 and the two second racks 9 are fixedly connected to the four pressure rods 3 respectively; a slag suction channel 13 is provided inside the fixed base 2, the input end of the slag suction channel 13 is arranged at the top center of the fixed base 2, and the output end of the slag suction channel 13 is arranged at one end of the side wall of the fixed base 2; the fixed base 2 is fixedly connected to a dust suction pipe 14 at the output end of the slag suction channel 13, and one end of the dust suction pipe 14 is connected to a dust collector 15, and the dust collector 15 is fixedly connected to the workbench 1;

[0027] In this embodiment, when it is necessary to perform internal thread processing on the copper tube, the copper tube is first placed vertically on the fixing seat 2, and then the first motor 4 is turned on. Under the drive of the first motor 4, the rotating shaft 5 will rotate, thereby driving the first gear 6 and the second gear 8 to rotate. When the first gear 6 rotates, it will drive the two first racks 7 to move synchronously in the opposite direction. When the second gear 8 rotates, it will drive the two second racks 9 to move synchronously in the opposite direction. The first rack 7 and the second rack 9 are in a vertical state. When the first rack 7 and the second rack 9 move, they will drive the four pressure rods 3 to move. Through the synchronous movement of the four pressure rods 3 , the copper tube on the fixing seat 2 can be clamped, so that the copper tube can remain stable during the internal thread processing. When the copper tube is internally threaded, a lot of debris will be generated. These debris will fall onto the fixing seat 2 and be located at the input port of the residue suction channel 13. At this time, the dust collector 15 is turned on. After the dust collector 15 is turned on, these debris will enter the inside of the dust collector 15 through the residue suction channel 13 and the dust suction pipe 14. Through this design, the debris generated during the internal thread processing of the copper tube can be cleaned up in time, thereby avoiding the impact of the debris on the processing and ensuring the air quality of the working environment.

[0028] like Figure 2 As shown, one end of the first rack 7 is fixedly connected to the first connecting rod 10, and one end of the second rack 9 is fixedly connected to the second connecting rod 11. The first connecting rod 10 and the second connecting rod 11 are both fixedly connected to the pressure rod 3. The workbench 1 is provided with four first through slots 12 around the fixed base 2. The first connecting rod 10 and the second connecting rod 11 are both slidably connected to the first through slots 12.

[0029] In this embodiment, the design of the first connecting rod 10 allows the first rack 7 to be smoothly fixedly connected to the pressure rod 3, and the design of the second connecting rod 11 allows the second rack 9 to be smoothly fixedly connected to the pressure rod 3. The design of the first through groove 12 allows the first rack 7 and the second rack 9 to be smoothly slidably connected to the workbench 1, so that the first rack 7 and the second rack 9 can smoothly drive the four pressure rods 3 to move.

[0030] like Figure 1 and Figure 4 As shown, the top of the workbench 1 is fixedly connected to a support frame 16, the top of the support frame 16 is rotatably connected to a turntable 17, one end of the turntable 17 is slidably connected to a moving block 18, the bottom of the moving block 18 is fixedly connected to an electric telescopic rod 19, the output end of the electric telescopic rod 19 is fixedly connected to a second motor 20, and the output end of the second motor 20 is fixedly connected to a milling cutter 21;

[0031] In this embodiment, when performing internal thread processing on the copper tube, the second motor 20 is first turned on, and the milling cutter 21 is driven to rotate by the second motor 20, and then the electric telescopic rod 19 is opened, and the milling cutter 21 is driven up and down by the electric telescopic rod 19 to allow the milling cutter 21 to enter the interior of the copper tube, and then the position of the moving block 18 is adjusted according to the diameter of the copper tube, and then the position of the milling cutter 21 is adjusted so that the milling cutter 21 can smoothly contact the inner wall of the copper tube and perform milling, thereby producing threads on the inner wall of the copper tube. During the processing, the turntable 17 needs to be rotated to drive the milling cutter 21 to rotate around the axis of the copper tube, so that the milling cutter 21 can mill a complete thread on the inner wall of the copper tube.

[0032] like Figure 6 As shown, a collar 22 is fixedly connected to the top of the support frame 16, and the turntable 17 is disposed in the collar 22 and is rotatably connected to the collar 22. A connecting ring 23 is fixedly connected to the top of the turntable 17, and a gear ring 24 is fixedly connected to the top of the connecting ring 23. A third motor 25 is fixedly connected to one end of the top of the support frame 16, and a third gear 26 is fixedly connected to the output end of the third motor 25. The third gear 26 is meshed with the gear ring 24.

[0033] In this embodiment, through the design of the ring 22, the turntable 17 can be smoothly connected to the support frame 16 for rotation. The third motor 25 can drive the third gear 26 to rotate, thereby driving the gear ring 24 to rotate. When the gear ring 24 rotates, it can drive the connecting ring 23 to rotate, thereby driving the turntable 17 to rotate, thereby providing driving force for the rotation of the turntable 17.

[0034] like Figure 5 As shown, a second through slot 27 is provided at one end of the turntable 17, and the second through slot 27 is slidably connected to the moving block 18. A sliding rod 28 is fixedly connected to one end of the connecting ring 23, and the sliding rod 28 is slidably connected to the moving block 18.

[0035] In this embodiment, the design of the second through slot 27 allows the moving block 18 to be smoothly slidably connected to the turntable 17 , and the design of the slide rod 28 allows the moving block 18 to be more stable when moving.

[0036] like Figure 6 As shown, a fourth motor 29 is fixedly connected to one end of the bottom of the turntable 17, a screw rod 30 is fixedly connected to the output end of the fourth motor 29, and the screw rod 30 is threadedly connected to the moving block 18. A connecting ear 31 is fixedly connected to the turntable 17 at a position adjacent to the second through slot 27, and the screw rod 30 is rotatably connected to the connecting ear 31;

[0037] In this embodiment, the fourth motor 29 drives the screw rod 30 to rotate, thereby driving the moving block 18 to move, thereby providing driving force for the movement of the moving block 18. The connecting ear 31 is designed to support one end of the screw rod 30, so that the screw rod 30 is more stable when rotating.

[0038] Working principle: When it is necessary to process the internal thread of the copper tube, first place the copper tube vertically on the fixed seat 2, then turn on the first motor 4, and under the drive of the first motor 4, the rotating shaft 5 will rotate, thereby driving the first gear 6 and the second gear 8 to rotate. When the first gear 6 rotates, it will drive the two first racks 7 to move synchronously in the opposite direction. When the second gear 8 rotates, it will drive the two second racks 9 to move synchronously in the opposite direction. The first rack 7 and the second rack 9 are in a vertical state. When the first rack 7 and the second rack 9 move, they will drive the first connecting rod 10 and the second rack 9 to move synchronously. The two connecting rods 11 move, which in turn drives the four pressure rods 3 to move. Through the synchronous movement of the four pressure rods 3, the copper tube on the fixing seat 2 can be clamped, so that the copper tube can remain stable during the internal thread processing. When the internal thread processing of the copper tube is performed, a lot of debris will be generated. These debris will fall onto the fixing seat 2 and be located at the input port of the residue suction channel 13. At this time, the vacuum cleaner 15 is turned on. After the vacuum cleaner 15 is turned on, these debris will enter the interior of the vacuum cleaner 15 through the residue suction channel 13 and the dust suction pipe 14. Through this design, the copper tube can be kept stable during the internal thread processing. The debris generated during the machining process can be cleaned up in time, thereby avoiding the debris from affecting the machining process and ensuring the air quality of the working environment. When the copper tube is internally threaded, the second motor 20 is first turned on, and the milling cutter 21 is driven to rotate by the second motor 20. Then, the electric telescopic rod 19 is opened, and the milling cutter 21 is driven up and down by the electric telescopic rod 19, so that the milling cutter 21 enters the interior of the copper tube. Then, the fourth motor 29 is turned on, and the fourth motor 29 drives the screw rod 30 to rotate, thereby driving the moving block 18 to move, so as to adjust the moving block according to the diameter of the copper tube. The position of the block 18 is adjusted, and then the position of the milling cutter 21 is adjusted, so that the milling cutter 21 can smoothly contact the inner wall of the copper tube and perform milling. During the processing, the turntable 17 needs to be rotated. At this time, the third motor 25 is turned on, and the third motor 25 can drive the third gear 26 to rotate, thereby driving the gear ring 24 to rotate. When the gear ring 24 rotates, it can drive the connecting ring 23 to rotate, and then drive the turntable 17 to rotate, thereby providing driving force for the rotation of the turntable 17, thereby driving the milling cutter 21 to rotate around the axis of the copper tube, so that the milling cutter 21 can mill a complete thread on the inner wall of the copper tube.

[0039] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
