Description

Technical Field

[0001] This utility model relates to the field of equipment for processing irregular tubes, specifically to a clamping and feeding mechanism for irregular tubes. Background Technology

[0002] In the cutting process of carbon steel profile tubes for doors, windows, and curtain walls, traditional methods often involve sawing, and fixed-length cutting usually relies on tooling and manual positioning and support. However, this method has many drawbacks:

[0003] First, manual positioning is affected by various factors, resulting in uncertainty in positioning accuracy. The operator's state, experience, force applied, and skill level all influence positioning accuracy, leading to inaccurate positioning and poor consistency. This uncertainty not only affects the cutting precision but may also cause difficulties in subsequent processing and assembly.

[0004] Secondly, manual loading and feeding are labor-intensive. Operators need to use tooling for positioning, which not only requires a certain level of skill and experience but also increases the difficulty of operation. Prolonged manual operation can easily lead to operator fatigue, thereby increasing the risk of errors.

[0005] Furthermore, poor consistency in manual positioning leads to inaccurate positioning. Due to the variability of manual operation, even the same operator performing positioning at different times may result in inconsistent positioning. This inconsistency not only affects the cutting quality but may also lead to product scrap and increased costs.

[0006] Finally, manual operation is inefficient. Traditional manual loading, positioning, and feeding methods are time-consuming and cannot meet the needs of large-scale production. Furthermore, manual operation has limited flexibility and cannot adapt to the cutting requirements of irregularly shaped tubes of different sizes. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a non-standard tube clamp feeding mechanism, which has the following advantages:

[0018] Achieve stable clamping and precise feeding:

[0019] Through the coordinated operation of multi-axis servo motor control and precision mechanical structure, this mechanism can ensure stable clamping and precise feeding of irregular tubes. The Z-axis servo motor and Y-axis servo motor control the vertical and horizontal movements respectively, enabling the irregular tubes to be accurately positioned during processing, thus improving the accuracy and reliability of processing.

[0020] Improve processing efficiency and flexibility:

[0021] The design of components such as the lifting frame, translation frame, and adjustment frame in the mechanism allows for flexible adjustment of the clamping position and feeding distance, adapting to the processing needs of irregularly shaped tubes of different sizes. This flexibility greatly improves processing efficiency and reduces the time wasted due to workpiece changes.

[0022] Enhance structural rigidity and stability:

[0023] The use of connecting frames, guide rails, guide screws, and other components enhances the rigidity and stability of the overall structure. This ensures that the mechanism maintains a stable clamping force during processing, avoiding processing errors caused by vibration or external interference.

[0024] The cylinder drives the pull rod to move the clamping plate on the adjusting plate, so as to easily clamp the workpiece. The inclined groove on the clamping plate is matched with the positioning rod on the adjusting plate to prevent the clamping from loosening due to the up and down movement of the workpiece during the clamping process.

[0025] Real-time monitoring of clamping status:

[0026] The photoelectric detection switch in the clamping assembly can monitor the clamping status in real time, ensuring that the irregularly shaped tube is firmly clamped. This real-time monitoring function can promptly detect and handle poor clamping, avoiding processing failures or workpiece damage caused by unstable clamping.

[0027] Easy to adjust and maintain:

[0028] The adjustable assembly allows for fine-tuning of the clamping component's position to accommodate irregularly shaped tubes of different sizes. Simultaneously, the handwheel locking mechanism ensures the adjusting threaded rod remains in place, preventing loosening. This design facilitates easy adjustment and maintenance during use, extending the mechanism's lifespan. Attached Figure Description

[0037] Working principles of various preferred technical solutions

[0038] Vertical (Z-axis) motion control

[0039] Z-axis servo motor 2: Fixedly mounted on the top of the frame 1, with a lifting threaded rod 7 connected to its output end. By rotating the lifting threaded rod 7, the lifting frame 3 is driven to move up and down along the guide rail 6, thereby achieving vertical position adjustment.

[0040] Guide rails 6: are set on both sides of the frame 1, and the lifting frame 3 is slidably mounted on them via lead screws on both sides to ensure the smooth movement of the lifting frame 3 in the vertical direction.

[0041] Horizontal (Y-axis) motion control

[0042] Y-axis servo motor 5: Fixedly mounted on translation frame 4, with its output end passing through translation frame 4 and equipped with transmission gear 21. During use, a guide rail adapted to the guide screw 22 at the bottom of translation frame 4 and the rear side of frame 1 can be configured, and a transmission rack adapted to the transmission gear 21 can be configured on the guide rail. The transmission gear 21 is driven by the Y-axis servo motor 5, which drives the entire translation frame 4 and its components to move horizontally on the guide rail, thereby achieving lateral positioning of the workpiece. A reduction motor can be configured at the output end of the Y-axis servo motor 5 to increase the driving torque of the Y-axis servo motor 5.

[0043] Adjustment and clamping mechanism

[0044] Adjustment assembly: includes adjustment slide rail 13, adjustment threaded rod 18, bracket, handwheel 12, and handwheel 12 locking device. By rotating the adjustment threaded rod 18, the position of the clamping assembly can be finely adjusted to ensure that it can adapt to irregularly shaped tubes of different sizes and shapes.

[0045] Handwheel 12 locking device: includes mounting bracket 15, upper locking bracket 16, lower locking bracket 17, and locking rod 19. The locking rod 19 passes through the upper locking bracket 16 and the lower locking bracket 17. By turning the locking rod 19 with the adjusting lever 20, the arc grooves on the lower locking bracket 17 and the upper locking bracket 16 are engaged with the adjusting threaded rod 18, thereby fixing the position of the adjusting threaded rod 18 and preventing loosening.

[0046] The clamping assembly includes a pressure plate 9, an adjusting plate 26, a clamping plate 25, a clamping block 10, a photoelectric detection switch 11, a cylinder 8, and a pull rod 24. The cylinder 8 provides power, which pulls the clamping plate 25 via the pull rod 24. Under the action of the inclined groove 27 and the positioning rod 28, the clamping plate 25 moves downward, thereby firmly clamping the shaped tube with the clamping block 10. The clamping status is monitored in real time by the photoelectric detection switch 11.

[0047] Connection and support

[0048] Connecting frame 14: Located at both ends of the adjusting frame 23, it is connected to the clamping plate 25 by bolts, which enhances the rigidity and stability of the overall structure.

[0049] Guide screw 22: It is fixedly installed at the rear end of the frame 1 and the bottom end of the translation frame 4 to ensure the smooth movement of the translation frame 4 in the horizontal direction.

[0050] Detailed Workflow

[0053] Adjust the parameters of each servo motor (such as speed, acceleration, etc.) according to the specific processing task, and calibrate the position of the photoelectric detection switch 11.

[0054] clamping workpiece

[0055] Place the irregularly shaped tube to be processed in a suitable position and use auxiliary tools to initially fix it to ensure that it will not shift during the clamping process.

[0056] Vertical positioning

[0057] Start the Z-axis servo motor 2, and rotate the lifting threaded rod 7 to move the lifting frame 3 up and down along the guide rail 6 until the clamping assembly reaches the predetermined height.

[0058] Horizontal positioning

[0059] A guide rail adapted to the guide screw 22 at the bottom of the translation frame 4 and the rear side of the frame 1 is configured, and a transmission rack and transmission gear 21 adapted to the guide rail are configured. The transmission gear 21 is driven by the Y-axis servo motor 5, which drives the entire translation frame 4 and its components to move horizontally on the guide rail, thereby achieving the lateral positioning of the workpiece and accurately aligning the clamping component with the shaped tube.

[0060] Adjustment and tightening

[0061] Use handwheel 12 to rotate adjusting threaded rod 18 to fine-tune the position of clamping assembly so that it can adapt to the specific size and shape of the irregular tube.

[0062] Operate the handwheel 12 to lock the position of the adjusting threaded rod 18, preventing it from loosening during subsequent processing.

[0063] Start cylinder 8, pull clamping plate 25 through pull rod 24, so that clamping block 10 firmly clamps the shaped tube, and confirm whether the clamping status is normal through photoelectric detection switch 11.

[0064] Feeding and processing

[0065] After ensuring that the irregular tube is stably clamped, start the feeding system and gradually advance or withdraw the workpiece according to the preset path to carry out the processing operation.

[0066] The photoelectric detection switch 11 continuously monitors the clamping status. Once an abnormality is detected (such as insufficient clamping force or loosening), it immediately issues an alarm and stops the equipment from operating.

[0067] Reset and unloading

[0068] After processing is completed, reverse the above steps, first release the clamping state of the clamping component, and then restore the entire mechanism to the initial position through the servo motor.

[0069] Remove the finished shaped tubes and prepare for the next processing task.

[0070] Maintenance

[0071] Regularly check the condition of each component, such as cleaning the guide rails, lubricating the lead screws, and replacing worn seals, to ensure that the device is always in optimal working condition.

[0072] Technological advantages

[0073] High precision: Multi-axis servo motor control ensures accurate positioning during each clamping and feeding, improving the consistency of processing quality.

[0074] Flexibility: By adjusting the design of the components, it can adapt to irregularly shaped tubes of different sizes and shapes, thus enhancing the application range of the equipment.

[0075] Safety: The built-in photoelectric detection switch 11 monitors the clamping status in real time. Once an abnormality is detected, protective measures are taken immediately to avoid potential safety hazards.

[0076] High degree of automation: The entire process is executed automatically by the control system, reducing the need for manual intervention and improving production efficiency.

[0077] Easy to maintain: The modular design makes it easy to disassemble and replace the components, simplifying daily maintenance and reducing repair costs.

[0078] In summary, the non-standard tube clamping and feeding mechanism provided by this utility model combines multiple advanced technologies and user-friendly designs, significantly improving the accuracy, reliability, and efficiency of the clamping and feeding process. It not only solves many problems existing in the prior art but also provides manufacturers with a high-precision, high-reliability solution, ensuring consistent and reliable product quality. Furthermore, the device is easy to maintain and expand, adaptable to different production needs, and has broad application prospects.
