Description

Technical Field

[0001] This application relates to the field of manufacturing machine tool functional components and accessories, and in particular to an intelligent adjustable center frame. Background Technology

[0002] The center rest plays a crucial role in the machining field, and it is widely used in equipment such as flatbed lathes, slantbed lathes, and CNC grinding machines. With the continuous advancement of technology and the booming development of the manufacturing industry, the requirements for precision and efficiency in parts machining are becoming increasingly stringent. Machining long cylindrical and long shaft parts has always been a technical challenge. Due to their large length, these parts are prone to vibration, bending deformation, and other problems during machining, affecting machining accuracy. Therefore, a center rest is needed to support the workpiece.

[0003] Traditional machining methods often rely on manually adjusted center rests to support the workpiece. Operators must rely on their experience to meticulously adjust the position and angle of the center rest to ensure the stability of the workpiece during machining. Furthermore, with the gradual development of technology, some semi-automatic center rests have emerged. These center rests utilize simple mechanical structures and basic control systems to automate some functions, thereby improving machining efficiency to a certain extent.

[0004] Regarding the aforementioned technologies, manually adjusted center supports are inefficient, requiring operators to spend a significant amount of time on manual operations. Their accuracy is unstable and easily affected by the operator's experience and skill level, making it difficult to ensure consistent precision in every machining operation. While semi-automatic center supports offer improvements in automation, their overall level of intelligence remains low, and they still cannot meet the precision requirements of modern machining. Summary of the Invention

[0005] To improve the machining accuracy of machine tools, this application provides an intelligent adjustable center rest.

[0006] This application provides an intelligent adjustment center frame, which adopts the following technical solution: An intelligent adjustable center frame includes a center frame body, a rotating mechanism, a clamping mechanism, and an information-based intelligent control system. The clamping mechanism includes two first clamping components and two second clamping components. The first clamping components are rotatably connected to the upper surface of the center frame body, and the second clamping components are fixedly connected to the center frame body and located below the first clamping components. The rotating mechanism is fixedly connected to the center frame body and drives the first clamping components to rotate. The clamping mechanism achieves clamping and positioning of the workpiece to be processed through its own extension and retraction. Both the first and second clamping components are equipped with pressure sensors and displacement sensors. The pressure sensors are used to detect the supporting force borne by the contact between the clamping mechanism and the workpiece to be processed, and the displacement sensors are used to detect the extension and retraction length of the clamping mechanism. Both the pressure sensors and the displacement sensors are connected to the information-based intelligent control system via signals. The information-based intelligent control system uses artificial intelligence algorithms to achieve intelligent adjustment capabilities for support and centering in automated parts production and processing.

[0007] By adopting the above technical solution, the main body of the center frame, the rotating mechanism, the clamping mechanism, and the information-based intelligent control system work together to achieve multiple functions of intelligent adjustment of the center frame. The rotating mechanism drives the first clamping component to rotate, working in conjunction with the fixed second clamping component to adapt to different types of workpieces, such as long cylindrical parts, long shaft parts, and complex workpieces, thus expanding the applicability of the center frame. The clamping mechanism clamps and positions the workpiece through its own extension and retraction. Pressure sensors on the first and second clamping components detect the support force in contact with the workpiece, and displacement sensors detect the extension and retraction length. These data are transmitted to the information-based intelligent control system. The information-based intelligent control system uses artificial intelligence algorithms to analyze and calculate based on the received signals, realizing intelligent adjustment of support and centering for automated workpiece production. It can precisely control the adjustment amount of the support points and drive the servo hydraulic system to adjust the position of the support points, ensuring that the workpiece is always in the optimal support state. Through real-time monitoring by various sensors, the intelligent adjustment of the support position can ensure that the positioning accuracy fluctuation is less than 0.01 mm during long-term operation, improving processing accuracy and meeting the requirements of high-precision manufacturing. Meanwhile, precise servo control enables second-level positioning adjustments, reducing manual adjustment time and downtime, and increasing productivity. Furthermore, it can automatically adjust the support position according to the workpiece size, enhancing processing flexibility and adaptability.

[0008] Optionally, the first clamping assembly and the second clamping assembly have the same structure, both including a hydraulic cylinder, a mounting plate, a clamping seat, and rollers. The cylinder body of the hydraulic cylinder is fixedly connected to the mounting plate, and the telescopic end of the hydraulic cylinder passes through the mounting plate and is fixedly connected to the clamping seat. A pressure sensing shaft is coaxially mounted on the rollers. The pressure sensing shaft is fixedly connected to the end of the clamping seat away from the hydraulic cylinder. A pressure sensing sensor is fixedly mounted on one end of the pressure sensing shaft, and a displacement sensor is fixedly mounted on the end of the hydraulic cylinder body away from the rollers. The mounting plate of the first clamping assembly is fixedly connected to the rotating mechanism, and the mounting plate of the second clamping assembly is fixedly connected to the main body of the central frame.

[0009] By adopting the above technical solution, the first clamping assembly and the second clamping assembly have the same structure, which facilitates production and maintenance; the hydraulic cylinder drives the roller to move to achieve clamping and positioning of the workpiece to be processed; the pressure sensing shaft and pressure sensing sensor can detect the supporting force borne by the roller in contact with the workpiece, providing data for intelligent adjustment; the mounting plate of the first clamping assembly is connected to the rotating mechanism, and the mounting plate of the second clamping assembly is connected to the main body of the center frame, realizing different installation methods. Together with the rotating mechanism, the entire clamping mechanism can adapt to different processing scenarios and meet the clamping needs of different parts such as long cylinders, long shafts and complex workpieces.

[0010] Optionally, the rotating mechanism includes a hydraulic motor, a drive shaft, and a limiting block. The limiting block is fixedly connected to the upper end face of the central frame body. The drive shaft is rotatably connected to the limiting block along its own axis. The upper end of the drive shaft passes through the limiting block and is fixedly connected to a rotating seat. The rotating seat is fixedly connected to the mounting plate of the first clamping assembly. The hydraulic motor is fixedly connected to the central frame body and is used to drive the drive shaft to rotate.

[0011] By adopting the above technical solution, the hydraulic motor provides power for the rotation of the drive shaft, and the limit block provides rotational support for the drive shaft, ensuring stable rotation of the drive shaft along its own axis. When the hydraulic motor drives the drive shaft to rotate, it can precisely drive the first clamping assembly to rotate, thereby flexibly adjusting the position and angle of the first clamping assembly to adapt to parts with different shapes, sizes, and processing requirements, enhancing the adaptability and processing flexibility of the intelligent adjusting center frame to different workpieces. This structural design enables the rotating mechanism to efficiently and stably realize the rotation function of the first clamping assembly, improving the positioning accuracy and processing efficiency during the processing, and meeting the needs of high-precision manufacturing.

[0012] Optionally, a base is fixedly provided at the lower end of the central frame body. The base is used to fasten the central frame body and the machine tool. The base includes a fixed seat and a locking seat. The fixed seat is fixedly connected to the lower end face of the central frame body. The locking seat is slidably connected to the lower part of the fixed seat in the vertical direction. Several fasteners are provided between the locking seat and the fixed seat. The machine tool track is located between the fixed seat and the locking seat.

[0013] By adopting the above technical solution, tightening the fasteners can move the locking seat closer to the fixed seat, thereby achieving a stable and fixed connection between the base and the machine tool interface, ensuring the installation stability of the center frame body on the machine tool, and thus ensuring the reliability of the intelligent adjustment center frame during operation, improving the support and positioning accuracy for parts processing.

[0014] Optionally, the rotating mechanism is detachably connected to the central frame body, the second clamping assembly is detachably connected to the central frame body, and the first clamping assembly is detachably connected to the rotating seat.

[0015] By adopting the above technical solution, the rotating mechanism and the main body of the center frame, the second clamping assembly and the main body of the center frame, and the first clamping assembly and the rotating seat are all detachably connected, realizing a modular design. This modular design allows the intelligent adjustable center frame to be quickly adjusted to adapt to different workpieces, effectively shortening the changeover time of the flexible production line and enhancing production flexibility. At the same time, each component can be independently disassembled and assembled, and in the event of equipment failure, the faulty component can be quickly located and replaced, shortening maintenance time and thus improving equipment utilization.

[0016] Optionally, a sector-shaped block is fixedly provided at the upper end of the transmission shaft, and a rotating seat is fixedly connected to the upper end face of the sector-shaped block. A rotating groove is provided at the upper end of the limiting block, and the sector-shaped block rotates in the rotating groove. The shape of the rotating groove is a combination of a semicircle and a rectangle. The semicircle is tangent to the adjacent side of the rectangle, and the diameter of the semicircle is the same as the diameter of the outer circle of the sector-shaped block. The inner circle of the sector-shaped block is tangent to the side of the rectangle away from the semicircle. When the transmission shaft is at the maximum or minimum rotation angle, one of the two side planes of the sector-shaped block is in contact with the side of the rectangle away from the semicircle.

[0017] By adopting the above technical solution, the sector block rotates in the rotating groove. The special shape of the rotating groove can limit the rotation range of the sector block, thereby limiting the continued rotation of the transmission shaft. When the transmission shaft is at its maximum or minimum rotation angle, the side plane of the sector block fits with the rectangular side, realizing precise limiting of the rotation angle of the first clamping component. This enhances the stable clamping and positioning of the workpiece to be processed by the intelligent adjustment center frame, and improves the processing accuracy and stability.

[0018] Optionally, a first hydraulic locking device is fixedly provided at one end of the mounting plate near the clamping seat, and the first hydraulic locking device is sleeved on the outside of the hydraulic cylinder telescopic shaft.

[0019] By adopting the above technical solution, the first hydraulic locking device can firmly lock the position of the hydraulic cylinder telescopic shaft after it is adjusted to a suitable position, preventing the hydraulic cylinder telescopic shaft from shifting due to external forces or vibrations during the clamping and positioning of the workpiece. This ensures the stability of the roller position and ensures that the workpiece is always in a stable supported state, effectively improving the support and positioning accuracy of the workpiece.

[0020] Optionally, protective housings are provided on the outer side of the first hydraulic locking device, the outer side of the end of the hydraulic cylinder away from the roller, and the outer side of the hydraulic motor. The main body of the center frame and the protective housing are both made of aerospace-grade aluminum alloy.

[0021] By adopting the above technical solution, the protective shell can protect the first hydraulic locking device, hydraulic cylinder, and rotating mechanism, preventing them from being damaged by external factors and extending their service life. The main body of the center frame and the protective shell are made of aerospace-grade aluminum alloy. Aerospace-grade aluminum alloy is lightweight and high-strength, which can reduce the overall weight of the intelligent adjustment center frame while maintaining high strength, thereby improving its overall motion response speed. This allows the center frame to respond to processing requirements more quickly and improve processing efficiency.

[0022] Optionally, a connecting plate is fixedly connected inside the main body of the central frame, and a second hydraulic locking device is fixedly provided at the upper end of the connecting plate. The second hydraulic locking device is sleeved on the outside of the transmission shaft.

[0023] By adopting the above technical solution, a connecting plate is fixedly connected inside the main body of the center frame, which enhances the connection stability and structural strength between the two plates of the center frame. A second hydraulic locking device, sleeved on the outside of the drive shaft, is installed at the upper end of the connecting plate. This device locks the drive shaft in place after it has rotated to the appropriate position, preventing it from rotating arbitrarily and ensuring the stability of the first clamping assembly. This, in turn, ensures stable clamping and positioning of the parts, improving machining accuracy. Furthermore, in conjunction with the automated control system of the entire intelligent adjusting center frame, it enables precise locking of the support point positions, meeting the requirements of high-precision manufacturing.

[0024] Optionally, the lower end of the drive shaft passes through the connecting plate and is coaxially fixedly connected to a folding plate, and the connecting plate is fixedly equipped with two rotational position proximity switches.

[0025] By adopting the above technical solution, when the drive shaft is at its maximum or minimum rotation angle, the folding plate will block the rotation position proximity switch. The rotation position proximity switch senses the rotation limit position of the drive shaft, thereby providing signal feedback to the information-based intelligent control system. This allows the intelligent control system to precisely control and adjust the rotation of the rotating mechanism, ensuring the accurate rotation angle of the first clamping component. This, in turn, guarantees the clamping and positioning accuracy of the workpiece to be processed, improving processing accuracy and quality.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The center frame body, rotating mechanism, clamping mechanism, and information-based intelligent control system work together to achieve multiple functions of intelligent adjustment of the center frame. The rotating mechanism drives the first clamping component to rotate, working in conjunction with the fixed second clamping component to adapt to different types of workpieces, such as long cylindrical parts, long shaft parts, and complex workpieces, thus expanding the applicability of the center frame. The clamping mechanism clamps and positions the workpiece through its own extension and retraction. Pressure sensors on the first and second clamping components detect the support force in contact with the workpiece, and displacement sensors detect the extension and retraction length. This data is transmitted to the information-based intelligent control system. The information-based intelligent control system uses artificial intelligence algorithms to analyze and calculate based on the received signals, realizing intelligent adjustment of support and centering for automated workpiece production. It can precisely control the adjustment amount of the support points and drive the servo hydraulic system to adjust the position of the support points, ensuring that the workpiece is always in the optimal support state. Through real-time monitoring by various sensors, the intelligent adjustment of the support position can ensure that the positioning accuracy fluctuation is less than 0.01 mm under long-term operation, improving processing accuracy and meeting the requirements of high-precision manufacturing. Meanwhile, precise servo control enables second-level positioning adjustments, reducing manual adjustment time and downtime, and increasing productivity. Furthermore, it can automatically adjust the support position according to the workpiece size, enhancing processing flexibility and adaptability. 2.

Together with the rotating mechanism, the entire clamping mechanism can adapt to different processing scenarios and meet the clamping requirements of different parts such as long cylinders, long shafts, and complex workpieces; 3. The hydraulic motor provides power for the rotation of the drive shaft, and the limit block provides rotational support for the drive shaft, ensuring stable rotation of the drive shaft along its own axis. When the hydraulic motor drives the drive shaft to rotate, it can precisely drive the first clamping assembly to rotate, thereby flexibly adjusting the position and angle of the first clamping assembly to adapt to parts of different shapes, sizes, and processing requirements, enhancing the adaptability and processing flexibility of the intelligent adjusting center frame to different workpieces. This structural design enables the rotating mechanism to efficiently and stably realize the rotation function of the first clamping assembly, improving the positioning accuracy and processing efficiency during the machining process, and meeting the needs of high-precision manufacturing.

The lower end of the horizontal part is fixedly connected to the base 4. Two inclined parts are symmetrically fixedly connected to both ends of the horizontal part. Two vertical parts are symmetrically arranged, and the lower end of the vertical part is fixedly connected to the adjacent inclined part.

The rotating mechanism 2 drives the first clamping assembly 31 to rotate, and the first clamping assembly 31 and the second clamping assembly 32 respectively abut against the sides of the part. This design is suitable for long cylindrical parts, long shaft parts, and complex workpieces. Simultaneously, during part loading, the rotating mechanism 2 can drive the first clamping assembly 31 to rotate, ensuring that the second clamping assembly 32 is unobstructed from above, facilitating loading.

A folding plate 223 is coaxially fixed to the lower end of the drive shaft 22 after passing through the connecting plate 11. Two rotational position proximity switches 111 are fixed to the connecting plate 11. The folding plate 223 consists of two plates, the included angle between which is the rotation angle of the drive shaft 22. Simultaneously, the central angle between the two rotational position proximity switches 111 and the drive shaft 22 is twice the rotation angle of the drive shaft 22. When the drive shaft 22 is at its maximum or minimum rotation angle, one of the plates of the folding plate 223 blocks the rotational position proximity switch 111.

[0049] Reference Figure 1This application embodiment also includes an information-based intelligent control system. Pressure sensor 3151 and displacement sensor 318 are both connected to the information-based intelligent control system via signals. Position sensors and vision cameras are installed on the machine tool bed. The position sensors detect the position of the workpiece to be processed, and the vision camera detects the shape of the workpiece. During operation, a closed-loop control system is formed by the hydraulic servo valve 317 and the built-in displacement sensor 318 of the hydraulic cylinder 311 to control the high-precision movement of the hydraulic cylinder 311. The pressure sensor at the front end of the servo hydraulic cylinder 311 senses the supporting force / pressure borne by the roller 314 in contact with the workpiece. The information-based intelligent control system calculates the adjustment amount of the support point according to a preset program and drives the servo hydraulic system to adjust the position of the support point. The first hydraulic locking device at each support point locks the position of the extension shaft of the hydraulic cylinder 311, fixing the position of the roller 314 and ensuring that the workpiece is always in the optimal support state. Through real-time monitoring by various sensors, the support position is intelligently adjusted to ensure that the positioning accuracy fluctuation is less than 0.01 mm during long-term operation, improving processing accuracy and meeting the requirements of high-precision manufacturing. Precise servo control enables second-level positioning and adjustment, reducing manual adjustment time, minimizing downtime, and increasing productivity. Automatic adjustment of the support position based on workpiece dimensions enhances processing flexibility and adaptability.

The clamping mechanism 3 clamps and positions the parts by its own extension and retraction. The pressure sensing sensor 3151 on the first clamping component 31 and the second clamping component 32 can detect the support force in contact with the parts, and the displacement sensor 318 detects the extension and retraction length. These data are transmitted to the information-based intelligent control system through signals. The information-based intelligent control system adopts artificial intelligence algorithms to analyze and calculate based on the received signals, realizing intelligent adjustment of support and centering for automated parts production and processing. It can accurately control the adjustment amount of the support points, drive the servo hydraulic system to adjust the position of the support points, and ensure that the workpiece is always in the optimal support state. Through real-time monitoring by various sensors, the support position is intelligently adjusted, ensuring positioning accuracy fluctuations of less than 0.01 mm during long-term operation, thus improving machining accuracy and meeting the demands of high-precision manufacturing. Simultaneously, precise servo control enables second-level positioning adjustments, reducing manual adjustment time and downtime, and increasing production capacity. Furthermore, it can automatically adjust the support position according to workpiece dimensions, enhancing machining flexibility and adaptability.

[0052] 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.
