Description

Technical Field

[0001] This invention relates to the field of copper bushing processing technology, specifically to a CNC machine tool for copper bushing processing. Background Technology

[0002] CNC machine tools, also known as computer numerical control machine tools, are mechatronic devices equipped with a dedicated CNC system that automatically completes cutting processes using digital codes. They can convert part drawings into code programs, and the machine tool automatically follows the program to perform cutting, replacing manual operation of ordinary machine tools.

[0003] CN215587889U discloses a CNC machine tool for machining copper sleeves, characterized by comprising a machine body, a three-jaw chuck, a tool holder, a pressing device, and a height adjustment device. The three-jaw chuck is mounted on the machine body and has jaws. The tool holder has a cutting tool, which is located on the same horizontal line as the three-jaw chuck. The tool holder is used to drive the cutting tool to move towards the three-jaw chuck. The pressing device is located between adjacent jaws. There are multiple pressing devices, which are evenly arranged circumferentially. The height adjustment device is connected to the pressing device and is used to adjust the distance between the pressing device and the three-jaw chuck. By adjusting the distance between the pressing device and the three-jaw chuck through the height adjustment device, the pressing device is brought closer to the end of the copper sleeve away from the jaws and presses that end tightly.

[0004] While the aforementioned applications and prior art can effectively clamp tall copper bushings and prevent them from loosening during processing, when using a three-jaw chuck to internally clamp the copper bushing, the low hardness of the copper bushing causes clamping marks, affecting subsequent normal use. Furthermore, when using an airbag to clamp and limit the copper bushing, small amounts of debris remain inside after processing, damaging the airbag and affecting the clamping effect. Additionally, when processing debris from excessively long copper bushings, the bushing may tilt slightly, preventing effective debris removal. Therefore, this application proposes a CNC machine tool for processing copper bushings. Summary of the Invention

[0009] Furthermore, the processing component includes a first rotating rod rotatably connected inside the placement tray, a first storage wheel fixedly connected to the surface of the first rotating rod, a first pull rope provided on the surface of the first storage wheel, and the end of the first pull rope away from the first storage wheel fixedly connected to one end of the support cylinder.

[0010] Furthermore, a cleaning disc is fixedly connected to one end of the first rotating rod. The cleaning disc has several storage slots and guide slots inside, and the storage slots and guide slots are connected to each other.

[0011] Furthermore, each of the aforementioned storage slots has a brush plate slidably connected inside. A guide rope is fixedly connected to one end of the brush plate near the guide slot, and a guide ball is fixedly connected to the other end of the guide rope away from the brush plate. The guide ball is slidably connected inside the guide slot.

[0012] Furthermore, the anti-tilt assembly includes two second rotating rods rotatably connected inside the placement tray.

A return spring is fixedly connected between the bottom of the sealing plate and the inside of the fixed box.

[0016] (III) Beneficial Effects Compared with the prior art, the present invention provides a CNC machine tool for machining copper bushings, which has the following beneficial effects: 1. This CNC machine tool for processing copper sleeves uses a soft support assembly to connect an external air source to an air inlet pipe. The drive motor is started, and through a drive rod, it drives a push gear to rotate. This causes the push gear plate to limit the copper sleeve via a limiting arc plate. Then, the push cylinder is activated, and through a telescopic rod, it moves a placement plate, causing the placement plate to pull an expansion airbag inside the copper sleeve. The air source enters the expansion airbag through the air inlet channel inside the support cylinder, causing the expansion airbag to inflate and support the copper sleeve, thus preventing marks.

[0017] 2. This CNC machine tool for processing copper sleeves, through the combined use of the soft support assembly and the processing assembly, during the movement of the placement disc, the first pull rope drives the first rotating rod to rotate through the first receiving wheel, causing the first rotating rod to drive the cleaning disc to rotate rapidly. During the rotation of the cleaning disc, centrifugal force is generated, which in turn drives the brush plate to move inside the receiving groove. As the cleaning disc rotates continuously, the bristles on the surface of the brush plate come into contact with the inner wall of the copper sleeve, thereby processing the debris attached to the inside of the copper sleeve and preventing the debris from damaging the expansion air bladder, thus achieving the effect of preventing damage.

[0018] 3. This CNC machine tool for processing copper sleeves utilizes a combination of a soft support assembly and an anti-tilting assembly. During the movement of the placement tray, the second pull rope drives the second rotating rod via the second receiving wheel. This rotating rod, through a half-gear, drives the frame toothed plate to slide back and forth. The frame toothed plate, in turn, drives the pushing plate via a push rod to slide back and forth inside the air supply cylinder. This continuously delivers air from inside the air supply cylinder to the fixed box via the air supply pipe. As the air inside the fixed box increases, the sealing plate moves the support bar, causing the rolling ball at the top of the support bar to contact the inner wall of the copper sleeve. Since one end of the inner wall of the copper sleeve contacts the limiting arc plate, the support bar and rolling ball on the surface of the placement tray support the inner wall of the copper sleeve when the placement tray and cleaning tray move, preventing the copper sleeve from tilting due to its excessive length. This achieves the effect of preventing tilting.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The devices or elements referred to in the embodiments of this application or implied herein must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the embodiments of this application. In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0024] For a specific implementation example, please refer to Implementation Example 1. Figures 1 to 4 A CNC machine tool for machining copper bushings includes: a machine tool 1 and a fixed housing 12 fixedly connected inside the machine tool 1, and further includes: The support cylinder 121 is fixedly connected inside the fixed box 12. The surface of the machining tool 1 is provided with a control panel 11, and the inside of the machining tool 1 is provided with a turning tool for machining copper sleeves. The soft support component 2 is set at one end of the support cylinder 121 and is used to provide soft support for the copper sleeve to be processed, so as to avoid damage to the copper sleeve by hard support. The soft support component 2 includes a push cylinder 21 fixedly connected to one end of the support cylinder 121. One end of the push cylinder 21 is differentially connected to a telescopic rod 211. One end of the telescopic rod 211 is fixedly connected to a placement plate 212. An expansion airbag 213 is fixedly connected between the placement plate 212 and the support cylinder 121. The processing component 3 is located at one end of the placement plate 212 and is used to process the debris inside the copper sleeve to prevent the debris from scratching the expansion airbag 213. The anti-tilting component 4 is located inside the placement plate 212 and is used to support the inside of the copper sleeve, thereby preventing the copper sleeve from tilting due to its excessive length. When the copper sleeve needs to be processed, the copper sleeve to be processed is placed on the surface of the support cylinder 121. Then, the soft support component 2 is activated, which drives the placement plate 212 to move, thereby inserting the expansion air bag 213 into the interior of the copper sleeve. Then, the movement of the placement plate 212 drives the processing component 3 to operate, so that the processing component 3 can process the residual debris inside the copper sleeve. At the same time, the movement of the placement plate 212 synchronously drives the anti-tilting component 4 to operate, so that the anti-tilting component 4 provides sliding support for the interior of the copper sleeve, thereby preventing the copper sleeve from tilting due to excessive length. Then, air is injected into the expansion air bag 213, so that the expansion air bag 213 supports the copper sleeve due to inflation. Then, the copper sleeve is processed by the turning tool inside the processing machine tool 1. For a specific embodiment two, please refer to Figures 1 to 6Based on the CNC machine tool for copper sleeve processing provided in Specific Embodiment 1, this embodiment provides a further technical solution: The support cylinder 121 has an air intake channel inside. The soft support assembly 2 also includes an air intake pipe 22 fixedly connected to the surface of the support cylinder 121. The air intake pipe 22 is connected to the inflatable airbag 213 through the air intake channel. The soft support assembly 2 also includes a drive motor 23 fixedly connected to one end of the support cylinder 121. The output end of the drive motor 23 is fixedly connected to a drive rod 231. A push gear 232 is fixedly connected to the surface of the drive rod 231. Several push tooth plates 233 are slidably connected inside the support cylinder 121. One end of each push tooth plate 233 is fixedly connected to a limit arc plate 234. The push gear 232 meshes with the push tooth plates 233 for transmission. It should be noted that the end of the limiting arc plate 234 away from the pushing tooth plate 233 is provided with a rubber layer. When the limiting arc plate 234 contacts the inner wall of the copper sleeve, the drive motor 23 is closed and the limiting arc plate 234 is always in contact with the inner wall of the copper sleeve. When it is necessary to provide soft support for the inner wall of the copper sleeve, connect the external air source to the air inlet pipe 22, then place the copper sleeve on the surface of the support cylinder 121, and then start the drive motor 23. The drive motor 23 drives the push gear 232 to rotate through the drive rod 231. The push gear 232 drives the push tooth plate 233 to move, so that the push tooth plate 233 initially limits the inner wall of the copper sleeve through the limiting arc plate 234. Then, turn off the drive motor 23 and start the push cylinder 21. The push cylinder 21 drives the placement plate 212 to move through the telescopic rod 211, so that the placement plate 212 pulls the expansion air bag 213 to move inside the copper sleeve. The air source enters the interior of the expansion air bag 213 through the air inlet channel inside the support cylinder 121, so that the expansion air bag 213 expands due to inflation and provides soft support for the copper sleeve, thereby avoiding damage to the inner wall of the copper sleeve caused by the use of the three-jaw chuck. For a specific embodiment three, please refer to Figures 1 to 10 Based on the CNC machine tool for copper sleeve processing provided in Specific Embodiment 2, this embodiment provides a further technical solution: The processing component 3 includes a first rotating rod 31 rotatably connected inside the placement tray 212. A first collecting wheel 311 is fixedly connected to the surface of the first rotating rod 31. A first pull rope 312 is provided on the surface of the first collecting wheel 311. One end of the first pull rope 312 away from the first collecting wheel 311 is fixedly connected to one end of the support cylinder 121. One end of the first rotating rod 31 is fixedly connected to a cleaning tray 32. The cleaning tray 32 has several collecting slots 321 and guide slots 322 inside. The several collecting slots 321 and guide slots 322 are connected. Brush plates 33 are slidably connected inside each of the several collecting slots 321. A guide rope 331 is fixedly connected to one end of the brush plate 33 near the guide slot 322. A guide ball 332 is fixedly connected to one end of the guide rope 331 away from the brush plate 33. The guide ball 332 is slidably connected inside the guide slot 322. It should be noted that a first torsion spring is provided on the surface of the first rotating rod 31. When the placement plate 212 evaporates to the initial state, the first torsion spring drives the first storage wheel 311 to reverse through the first rotating rod 31, thereby re-storing the first pull rope 312 on the surface of the first storage wheel 311. When it is necessary to remove residual debris from the inner wall of the copper sleeve to prevent the debris from scratching the expansion airbag 213, during the movement of the placement tray 212, since one end of the first pull rope 312 is fixedly connected to one end of the support cylinder 121, the first pull rope 312 drives the first rotating rod 31 to rotate through the first collection wheel 311, causing the first rotating rod 31 to drive the cleaning tray 32 to rotate rapidly. During the rotation of the cleaning tray 32, centrifugal force is generated, which in turn drives the brush plate 33 to move inside the collection groove 321. As the cleaning tray 32 rotates continuously, the bristles on the surface of the brush plate 33 come into contact with the inner wall of the copper sleeve, thereby removing the debris attached to the inside of the copper sleeve. As the placement tray 212 moves continuously, the bristles on the surface of the brush plate 33 push the debris away, thereby preventing the debris from damaging the expansion airbag 213 and affecting its subsequent normal use. For a specific implementation example, please refer to Implementation Example 4. Figures 1 to 15 Based on the CNC machine tool for copper sleeve machining provided in Specific Embodiment 3, this embodiment provides a further technical solution: The anti-tilt assembly 4 includes two second rotating rods 41 rotatably connected inside the placement tray 212. A second collecting wheel 411 is fixedly connected to the surface of each of the two second rotating rods 41. A second pull rope 412 is provided on the surface of each second collecting wheel 411. One end of the second pull rope 412 away from the second collecting wheel 411 is fixedly connected to one end of the support cylinder 121. Half gears 413 are fixedly connected to the surface of each of the two second rotating rods 41. The anti-tilt assembly 4 also includes two frame toothed plates 42 slidably connected inside the placement tray 212 and several air supply cylinders 43 fixedly connected inside the placement tray 212. The half gears 413 mesh with the frame toothed plates 42 for transmission. Push rods 421 are fixedly connected to the surface and back of each of the two frame toothed plates 42. The top of the push rod 421 is fixedly connected to the push plate 422, which is slidably connected inside the air cylinder 43. The anti-tilt assembly 4 also includes two fixed boxes 44 fixedly connected inside the placement plate 212. The top of the air cylinder 43 is fixedly connected to the exhaust pipe 431, and the surface of the exhaust pipe 431 is provided with a pressure relief valve 432. The air cylinder 43 and the fixed box 44 are connected through the air pipe 433. The interior of each of the two fixed boxes 44 is slidably connected to a sealing plate 441. The top of the sealing plate 441 is fixedly connected to a support bar 442, and the top of the support bar 442 is provided with several rolling balls 443. The bottom of the sealing plate 441 and the interior of the fixed box 44 are fixedly connected to a return spring 444. It should be noted that a second torsion spring is provided on the surface of the second rotating rod 41. When the placement disc 212 evaporates to its initial state, the second torsion spring drives the second storage wheel 411 to reverse through the second rotating rod 41, causing the second storage wheel 411 to retract the second pull rope 412. A first one-way valve is provided on the surface of the pushing disc 422, and a second one-way valve is provided on the surface of the air supply pipe 433. When the pushing disc 422 moves closer to the air supply pipe 433, the first one-way valve closes and the second one-way valve opens, thereby supplying air from inside the air supply cylinder 43 to the interior of the fixed box 44 through the air supply pipe 433. When the disc 422 moves away from the air supply pipe 433, the first one-way valve opens and the second one-way valve closes, thereby introducing outside air back into the air supply cylinder 43. When the sealing plate 441 stops rising, the air pressure inside the air supply cylinder 43 reaches the threshold of the pressure relief valve 432, causing the air inside the air supply cylinder 43 to be discharged through the exhaust pipe 431. The surface of the fixed box 44 is equipped with a solenoid valve. The control panel 11 is electrically connected to the push cylinder 21, the drive motor 23 and the solenoid valve. The opening and closing of the push cylinder 21, the drive motor 23 and the solenoid valve can be controlled by the operating program of the temporal part of the control panel 11. To prevent the copper sleeve from tilting due to its excessive length, which could affect the removal of residual debris, during the movement of the placement tray 212, one end of the second pull rope 412 is fixedly connected to one end of the support cylinder 121. Therefore, the second pull rope 412 drives the second rotating rod 41 to rotate via the second collecting wheel 411. This causes the second rotating rod 41 to drive the frame toothed plate 42 to slide back and forth via the half gear 413. Consequently, the frame toothed plate 42 drives the pushing disc 422 to slide back and forth inside the air delivery cylinder 43 via the push rod 421, thus moving the air delivery cylinder 43... The internal air is continuously supplied to the interior of the fixed box 44 through the air supply pipe 433. As the air inside the fixed box 44 increases, the sealing plate 441 moves the support bar 442, which in turn causes the rolling ball 443 at the top of the support bar 442 to contact the inner wall of the copper sleeve. Since the inner wall of one end of the copper sleeve is in contact with the limiting arc plate 234, when the placement tray 212 and the cleaning tray 32 move, the support bar 442 and the rolling ball 443 on the surface of the placement tray 212 can support the inner wall of the copper sleeve, thereby preventing the copper sleeve from tilting due to excessive length. Working principle: In use, the copper sleeve to be processed is placed on the surface of the support cylinder 121. The external air source is connected to the air inlet pipe 22. Then, the copper sleeve is placed on the surface of the support cylinder 121. The drive motor 23 is then started. The drive motor 23 drives the push gear 232 to rotate via the drive rod 231. The push gear 232 drives the push tooth plate 233 to move, so that the push tooth plate 233 initially limits the inner wall of the copper sleeve through the limiting arc plate 234. Then, the drive motor 23 is turned off and the push cylinder 21 is started. The push cylinder 21 drives the placement plate 212 to move via the telescopic rod 211. The placement plate 212 pulls the inflatable air bag 213 to move inside the copper sleeve. The air source enters the inflatable airbag 213 through the air intake channel inside the support cylinder 121, causing the inflatable airbag 213 to expand and provide soft support for the copper sleeve, thus avoiding damage to the inner wall of the copper sleeve caused by the use of the three-jaw chuck. During the movement of the placement plate 212, since one end of the first pull rope 312 is fixedly connected to one end of the support cylinder 121, the first pull rope 312 drives the first rotating rod 31 to rotate through the first receiving wheel 311. The first rotating rod 31 drives the cleaning plate 32 to rotate rapidly. During the rotation of the cleaning plate 32, centrifugal force is generated, which in turn drives the brush plate 33 to move inside the receiving groove 321. As the cleaning plate 32 rotates continuously, the brush plate 33 moves within the receiving groove 321. The bristles on the surface of the brush plate 33 contact the inner wall of the copper sleeve, thereby processing the debris attached to the inside of the copper sleeve. As the placement tray 212 moves continuously, the bristles on the surface of the brush plate 33 push the debris away, thus preventing the debris from damaging the inflatable airbag 213 and affecting its subsequent normal use. During the movement of the placement tray 212, since one end of the second pull rope 412 is fixedly connected to one end of the support cylinder 121, the second pull rope 412 drives the second rotating rod 41 to rotate through the second storage wheel 411. The second rotating rod 41 drives the frame toothed plate 42 to slide back and forth through the half gear 413, thereby causing the frame toothed plate 42 to drive the push plate 422 through the push rod 421. The air cylinder 43 slides back and forth inside, continuously supplying air from inside the air cylinder 43 to the inside of the fixed box 44 through the air supply pipe 433. As the air inside the fixed box 44 increases, the sealing plate 441 moves the support bar 442, causing the rolling ball 443 at the top of the support bar 442 to contact the inner wall of the copper sleeve. Since the inner wall of one end of the copper sleeve is in contact with the limiting arc plate 234, when the placement tray 212 and the cleaning tray 32 move, the support bar 442 and the rolling ball 443 on the surface of the placement tray 212 can support the inner wall of the copper sleeve, thereby preventing the copper sleeve from tilting due to excessive length. Then, the copper sleeve is processed by the turning tool inside the processing machine tool 1.
