Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to an integrated machine for chamfering and marking pipes. Background Technology

[0002] In the field of machining, pipe processing is an important and widely used process. With the continuous development of industry, the requirements for efficiency and quality in pipe processing are also increasing. Chamfering and marking of pipes play a crucial role in many industries, such as construction, machinery manufacturing, and the automotive industry. In the construction sector, chamfered and accurately marked pipes enable better connections and installation, improving the stability and safety of building structures.

[0003] In the existing pipe processing, the chamfering and marking operations of pipes are usually carried out step by step. A separate chamfering device is generally used. The pipe is placed on the device manually, and the end of the pipe is cut by the rotation of the cutting tool to achieve the required chamfer size. After the chamfering is completed, the pipe needs to be transferred to the marking station, where the required information is marked on the surface of the pipe by laser marking, inkjet marking, or other methods.

[0004] Regarding the aforementioned technologies, since different equipment is required for chamfering and marking operations, operators need to frequently switch between different equipment during pipe processing. Each clamping requires a certain amount of time to ensure the accurate positioning of the pipe, and the transfer process may also be affected by various factors, making the pipe processing inconvenient. Utility Model Content

[0005] To improve the convenience of pipe processing, this application provides an integrated pipe chamfering and marking machine.

[0006] This application provides an integrated machine for chamfering and marking pipes, which adopts the following technical solution: A pipe chamfering and marking integrated machine includes a machine base, a clamping assembly at the upper end of the machine base for clamping the pipe, a cutting tool at the upper end of the machine base located on one side of the clamping assembly, a motor located on the side of the cutting tool away from the pipe, the motor being fixedly connected to the machine base and used to drive the cutting tool to rotate, a first marking unit, a second marking unit, and a third marking unit at the upper end of the machine frame, the first marking unit being evenly spaced along the circumference of the pipe, the first marking unit being located at the upper end of the pipe and being slidably connected to the machine base vertically, the second marking unit and the third marking unit being symmetrically distributed along the axis of the pipe, and a three-dimensional lifting platform at the lower end of each of the second and third marking units for moving them.

[0007] By adopting the above technical solution, after the clamping assembly securely clamps the pipe in one go, both chamfering and marking are completed based on the same reference position. The motor drives the cutter to rotate precisely to achieve chamfering. The first, second, and third marking units are evenly distributed along the circumference of the pipe. This layout can meet the marking needs of different positions on the pipe. The first marking unit is located at the upper end of the pipe and can mark the top of the pipe. The second and third marking units are symmetrically distributed along the axis of the pipe and can cover the marking area on the side of the pipe, thus completing the full circumferential marking of the pipe. The second and third marking units can move in multiple directions through a three-dimensional lifting platform to adapt to the processing needs of pipes of different lengths. Integrating the chamfering and marking processes into the same machine, operators do not need to transfer pipes between machines, reducing the handling time during process changes. At the same time, the pipe does not need to be repeatedly calibrated and positioned, improving the convenience of the device.

[0008] Optionally, the clamping assembly includes a cylinder, a connecting frame, and a clamping plate. The connecting frame is fixed to the upper end of the machine base, and a connecting hole is opened at the upper end of the connecting frame. The pipe passes through the connecting hole. The cylinder is fixed to the upper end of the machine base and is located at the lower end of the connecting frame. The clamping plate is located at the upper end of the connecting frame and is fixedly connected to the output end of the cylinder. The clamping plate and the connecting frame cooperate to limit the pipe.

[0009] By adopting the above technical solution, the connecting hole at the upper end of the connecting frame provides a precise placement channel for the pipe. When the cylinder is started, its output end drives the clamping plate to move upward. The clamping plate and the connecting frame form an upper and lower clamping structure to limit the pipe and reduce the shaking, displacement or rotation of the pipe during processing, thus ensuring the stability and reliability of the processing.

[0010] Optionally, a pad made of elastic material is fixed to the side of the pallet near the tube.

[0011] By adopting the above technical solution, the soft pad made of elastic material is soft and can form a flexible buffer when in contact with the pipe, reducing the friction or squeezing between the clamping plate and the pipe surface, and effectively reducing the damage such as scratches and indentations on the pipe surface.

[0012] Optionally, the tool includes a tool holder and a machining tool. The tool holder is located between the motor and the clamping assembly and is coaxially fixed with the motor output shaft. The machining tool is located inside the tool holder and is detachably connected to the tool holder.

[0013] By adopting the above technical solution, the tool holder and the motor output shaft are fixed coaxially, ensuring that the rotation trajectory of the processing tool is accurate and stable when the motor drives the tool holder to rotate, so that the processing tool can stably process the pipe. The processing tool and the tool holder are detachably connected. When it is necessary to process pipes of different specifications and materials, or to switch different chamfer angles, the operator can quickly disassemble the old processing tool and replace it with a suitable tool without replacing the entire tool holder, thus improving the convenience of using the device.

[0014] Optionally, the lower end of the machine tool is provided with several rollers, which are evenly distributed at the end of the machine tool, and a brake pad is provided on one side of each roller.

[0015] By adopting the above technical solution, several evenly distributed rollers provide the machine with convenient mobility. Operators can easily push the equipment to adjust its position without the need for large handling tools. The brake pads can quickly lock the rollers after the equipment is moved to the target position, reducing the probability of the machine shifting due to external forces during operation and improving the stability of the device.

[0016] Optionally, the three-dimensional lifting platform includes a lifting platform, a first translation plate and a second translation plate. The lifting platform is located at the upper end of the machine platform and is detachably connected to the machine platform. The first translation plate is located at the upper end of the lifting platform and is slidably connected to the lifting platform along the width of the lifting platform. The second translation plate is located at the upper end of the first translation plate and is slidably connected to the first translation plate along the length of the first translation plate. The second marking unit or the third marking unit is fixed at the upper end of the second translation plate.

[0017] By adopting the above technical solution, the lifting platform allows the second and third marking units to be height-adjusted according to pipe diameters. The first translation plate is located at the upper end of the lifting platform and is slidably connected to it along its width. During marking, the position of the first translation plate can be flexibly adjusted according to the specific marking location on the pipe, thus accurately moving the marking unit to the target position. The second translation plate is located at the upper end of the first translation plate and is slidably connected to it along its length, allowing either the second or third marking unit to move freely in the transverse direction of the pipe, enabling marking at different transverse positions.

[0018] Optionally, the upper end of the machine platform is provided with several mounting holes, which are evenly distributed along the upper surface of the machine platform. The lower end of the lifting platform is provided with several screws, which pass through the lifting platform and are threaded to the inner wall of the mounting holes.

[0019] By adopting the above technical solution, several mounting holes evenly distributed on the upper part of the machine platform provide multiple optional installation points for the lifting platform. Operators can adjust the installation position of the lifting platform on the machine platform according to the pipe specifications and marking position requirements, improving the flexibility of the device's use. The threaded connection between the screws and the inner wall of the mounting holes has extremely strong fastening power, which can firmly fix the lifting platform on the machine platform, improving the stability of the device's use.

[0020] Optionally, a connecting block is provided at the upper end of the machine base. The connecting block is detachably connected to the machine base. A connecting bracket is provided on one side of the connecting block. The connecting bracket is hinged to the connecting block. A display screen is provided at the end of the connecting bracket away from the connecting block. The display screen is rotatably connected to the connecting bracket. The display screen is used to control the marking process of the pipe.

[0021] By adopting the above technical solution, the connecting bracket and the connecting block are hinged, allowing the connecting bracket to rotate at multiple angles around the hinge point. Simultaneously, the display screen is rotatably connected to the connecting bracket, further increasing the freedom of adjustment for the display screen angle. Operators can flexibly adjust the angle and direction of the display screen according to their height and observation needs. Operators can monitor marking parameters, equipment status, and marking effects in real time through the display screen, and make timely adjustments and controls, improving the ease of use of the device.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By integrating the chamfering and marking processes into the same machine, operators no longer need to transfer pipes between machines, reducing handling time during process changes. At the same time, the pipes do not need to be repeatedly calibrated and positioned, improving the ease of use of the equipment. 2. When the cylinder is started, its output end drives the clamping plate to move upward. The clamping plate and the connecting frame form an upper and lower clamping structure to limit the pipe and reduce the shaking, displacement or rotation of the pipe during processing, thus ensuring the stability and reliability of the processing. 3. Several connection holes evenly distributed on the upper part of the machine platform provide multiple optional installation points for the lifting platform. Operators can adjust the installation position of the lifting platform on the machine platform according to the pipe specifications and marking position requirements, thereby improving the flexibility of the device.

[0031] This application discloses an integrated machine for chamfering and marking pipes. Example

[0032] Reference Figure 1 and Figure 2 A pipe chamfering and marking integrated machine includes a machine base 1. A connecting frame 22 is fixedly provided at the upper end of the machine base 1. A connecting hole is opened at the upper end of the connecting frame 22. When processing the pipe 4, the pipe 4 is placed into the connecting hole. At this time, the inner wall of the connecting hole supports the pipe 4. A cylinder 21 is fixedly provided at the upper end of the machine base 1. The cylinder 21 is located at the lower end of the connecting frame 22. A clamping plate 23 is provided at the upper end of the connecting frame 22. The clamping plate 23 is fixedly connected to the output end of the cylinder 21. After the pipe 4 enters the connecting hole, the cylinder 21 starts and drives the clamping plate 23 to move vertically. After the clamping plate 23 moves upward and contacts the pipe 4, it forms an upper and lower clamping structure with the connecting frame 22 to limit the pipe 4 and reduce the shaking, displacement or rotation of the pipe 4 during processing, thus ensuring the stability and reliability of the processing process.

[0033] Reference Figure 3 and Figure 4 A tool holder 12 is provided on one side of the connecting frame 22, and a motor 122 is provided on the upper end of the machine base 1. The output shaft of the motor 122 is coaxially fixed with the tool holder 12. When the pipe 4 is chamfered, the motor 122 starts and drives the tool holder 12 to rotate. The tool holder 12 is equipped with a processing tool 121. The rotation of the tool holder 12 drives the processing tool 121 to rotate, so that the processing tool 121 processes the pipe 4. The processing tool 121 is detachably connected to the tool holder 12. When the processing tool 121 is damaged or different chamfering angles need to be switched, the operator can quickly disassemble the old processing tool 121 and replace it with a suitable tool without replacing the entire tool holder 12, thus improving the convenience of using the device.

[0034] Reference Figure 2 The upper end of the frame is equipped with a first marking unit 146, a second marking unit 374, and a third marking unit 375. The first marking unit 146, the second marking unit 374, and the third marking unit 375 are evenly distributed along the circumference of the pipe 4. The first marking unit 146 is located at the upper end of the pipe 4 and can mark the top of the pipe 4. The second marking unit 374 and the third marking unit 375 are symmetrically distributed along the axis of the pipe 4 and can cover the marking area on the side of the pipe 4, thereby completing the full circumference marking of the pipe 4. The entire device integrates the chamfering and marking processes on the same machine 1. The operator does not need to transfer the pipe 4 between equipment, reducing the handling time during process switching. At the same time, the pipe 4 does not need to be repeatedly calibrated and positioned, improving the convenience of using the device.

[0035] Reference Figure 5 and Figure 6 The upper end of the machine base 1 is provided with a connecting block 14, which is detachably connected to the machine base 1. The connecting block 14 is provided with a threaded rod 144, which is rotatably connected to the connecting block 14. The upper end of the threaded rod 144 is fixed with a rotating handle 143. Rotating the rotating handle 143 causes the threaded rod 144 to rotate. One end of the threaded rod 144 is provided with a driving block 145, which is threadedly connected to the threaded rod 144. One side of the driving block 145 is fixedly connected to the first marking unit 146. The connecting block 14 limits the driving block 145. The rotation of the threaded rod 144 causes the driving block 145 to move vertically. The vertical movement of the driving block 145 causes the first marking unit 146 to move vertically, thereby enabling the marking of pipes 4 of different sizes.

[0036] Reference Figure 7 and Figure 8The lower ends of the second marking unit 374 and the third marking unit 375 are both equipped with a three-dimensional lifting platform 3. The three-dimensional lifting platform 3 includes a base 31, two connecting rods 32, two connecting rods 33, a lifting plate 34, a knob 35, a lead screw 351, a translation plate 37, and a translation plate 36. The base 31 is located at the upper end of the machine base 1 and is detachably connected to the machine base 1. The lifting plate 34 is located at the upper end of the base 31. The connecting rods 32 and 33 are both located between the base 31 and the lifting plate 34. The connecting rods 32 and 33 correspond one-to-one, and the connecting rods 32 and 33 are rotatably connected to each other. One end of the connecting rods 32 and 33 is rotatably connected to the base 31 and the lifting plate 34, and the other end is slidably connected to the base 31 and the lifting plate 34 laterally.

[0037] Reference Figure 7 and Figure 8 A lead screw 351 is rotatably connected to the lower end of the lifting plate 34. A knob 35 is fixed to one end of the lead screw 351. Rotating the knob 35 causes the lead screw 351 to rotate. A moving block 352 is provided at the end of the lead screw 351 near the knob 35. The moving block 352 is threadedly connected to the lead screw 351, and the moving block 352 is fixedly connected to the end of the connecting rod 33 near the lifting plate 34. The lifting plate 34 limits the moving block 352. The rotation of the lead screw 351 causes the moving block 352 to move laterally. The lateral movement of the moving block 352 causes the connecting rod 32 and the connecting rod 33 to slide laterally, thereby realizing the lifting of the lifting plate 34.

[0038] Reference Figure 7 and Figure 8 The upper end of the lifting plate 34 is provided with a second lead screw 372, which is rotatably connected to the lifting plate 34. One end of the second lead screw 372 is fixedly provided with a first rotating block 371. Rotating the first rotating block 371 causes the second lead screw 372 to rotate. One end of the second lead screw 372 is provided with a second moving block 373, which is threadedly connected to the second lead screw 372. The lifting plate 34 limits the second moving block 373. Rotating the second lead screw 372 causes the second moving block 373 to move along the length of the second lead screw 372. The first translation plate 37 is located at the upper end of the lifting plate 34 and is fixedly connected to the second moving block 373. Moving the second moving block 373 causes the first translation plate 37 to move.

[0039] Reference Figure 7 and Figure 8The upper end of the translation plate 37 is provided with a lead screw 362, which is rotatably connected to the translation plate 37. One end of the lead screw 362 is fixed with a rotating block 361. Rotating the rotating block 361 causes the lead screw 362 to rotate. One end of the lead screw 362 is provided with a moving block 363, which is threadedly connected to the lead screw 362. The translation plate 37 limits the moving block 363. The movement of the lead screw 362 causes the moving block to move along the length of the translation plate 37. The translation plate 36 is located at the upper end of the translation plate 37, and the translation plate 36 is fixedly connected to the moving block 363. The movement of the moving block 363 causes the translation plate 36 to move along the length of the translation plate 37. The second marking unit 374 or the third marking unit 375 is fixedly installed at the upper end of the translation plate 36.

[0040] Reference Figure 7 and Figure 8 When processing pipes 4 with larger diameters, the lifting platform 34 can be raised to position the second marking unit 374 or the third marking unit 375, fixed on the second translational platform 36, at a suitable height, ensuring accurate marking. For pipes 4 with smaller diameters, the lifting platform is lowered to avoid improper distance between the marking unit and the pipe 4, which could affect the marking quality, thus meeting the marking requirements of pipes 4 with various diameters. The movement of the first translational platform 37 and the second translational platform 36 can be flexibly adjusted according to the specific marking position required on the pipe 4, thereby accurately moving the marking unit to the target position.

[0041] Reference Figure 5 and Figure 6 A connecting bracket 141 is provided on one side of the connecting block 14. The connecting bracket 141 is hinged to the connecting block 14, allowing the connecting bracket 141 to rotate at multiple angles around the hinge point. A display screen 142 is provided at the end of the connecting bracket 141 away from the connecting block 14. The display screen 142 is rotatably connected to the connecting bracket 141, increasing the freedom of angle adjustment of the display screen 142. Operators can flexibly adjust the angle and direction of the display screen 142 according to their height and observation needs. Operators can monitor the marking parameters, equipment status, and marking effect in real time through the display screen 142, and make timely adjustments and controls, improving the convenience of using the device.

[0042] Reference Figure 1The upper end of the machine base 1 has several mounting holes 13, which are evenly distributed along the upper surface of the machine base 1, providing multiple optional mounting points for the base 31. Operators can adjust the mounting position of the base 31 on the machine base 1 according to the specifications of the pipe 4 and the marking position requirements, improving the flexibility of the device. The lower end of the base 31 has several screws, which pass through the base 31 and are threaded into the inner wall of the mounting holes 13. The threaded connection has extremely strong fastening power, which can fix the base 31 on the machine base 1, improving the stability of the device.

[0043] Reference Figure 4 A soft pad 24 is fixed on the side of the clamping plate 23 near the pipe 4. The soft pad 24, made of elastic material, is soft and can form a flexible buffer when in contact with the pipe 4, reducing the friction or pressure between the clamping plate 23 and the surface of the pipe 4. This effectively reduces scratches, indentations, and other damage to the surface of the pipe 4. At the same time, the soft pad 24 has elastic deformation capability, and will conform to the outer contour of the pipe 4 during clamping, increasing the contact area with the pipe 4. This not only disperses the clamping pressure but also reduces the deformation of the pipe 4 caused by excessive local pressure.

[0044] Reference Figure 1 The machine base 1 has several rollers 11 evenly distributed at its lower end. These rollers provide convenient mobility, allowing operators to easily move the equipment and adjust its position without the need for large handling tools. Each roller 11 has a brake pad 111 on one side, ensuring stable positioning of the machine base 1. Once the machine base 1 is moved to a suitable working position, the operator can lock the rollers 111 by operating the brake pads, reducing the probability of displacement due to external forces during operation and improving the stability of the device.

[0045] The implementation principle of the pipe chamfering and marking integrated machine in this application embodiment is as follows: When processing the pipe 4, the pipe 4 is placed at the connection hole, the cylinder 21 drives the clamping plate 23 to move vertically to limit the pipe 4, the motor 122 starts to drive the cutter to rotate, the cutter processes the pipe 4, and at the same time the first marking unit 146, the second marking unit 374 and the third marking unit 375 mark the pipe 4. The chamfering and marking processes are integrated into the same machine 1, the operator does not need to transfer the pipe 4 between equipment, reducing the handling time during process switching, and the pipe 4 does not need to be repeatedly calibrated and positioned, improving the convenience of using the device.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
