Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a servo-positioned master saw device. Background Technology

[0002] In woodworking machinery, the lifting accuracy of the main saw directly affects the control of the grooving depth. Currently, in industrial applications, the main saw lifting mechanism generally relies on a single power source: pneumatic or electric. Specifically, this manifests as either a linear cylinder drive using compressed air or an electric cylinder drive using a servo motor. While the cylinder drive is simple in structure and has a fast response, its working characteristics are significantly affected by gas compressibility and pressure fluctuations. This makes precise control during saw blade height adjustment difficult, and in scenarios requiring precise grooving depth control, positioning deviations are prone to occur, leading to unstable processing quality and failing to meet high-precision processing requirements. While the electric cylinder drive significantly improves lifting accuracy compared to the pneumatic drive, better meeting the needs of some high-precision processing scenarios, its speed is slower. This drawback is particularly pronounced in production environments that prioritize processing efficiency. Furthermore, the electric cylinder drive consumes more energy, increasing production costs and contradicting the current trend of energy conservation and emission reduction in industrial development. Therefore, traditional main saw devices use a single drive method, whether it is pneumatic or electric cylinder driven, which makes it difficult to meet the needs of processing accuracy, speed and energy consumption, and cannot adapt to the increasingly diversified processing needs of the woodworking industry. Utility Model Content

[0003] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a servo-positioning main saw device, which solves the technical problems of the contradiction between accuracy and speed and the difficulty in coordinating and optimizing energy consumption and efficiency in the lifting control of traditional single-power-source main saw devices.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model discloses a servo-positioned main saw device, comprising a support frame, a main saw module, a servo electric cylinder, and a servo air cylinder. The main saw module is longitudinally slidably mounted on the support frame. The servo electric cylinder is fixed to one side of the support frame, and the servo air cylinder is fixed to the side of the support frame away from the servo electric cylinder. The transmission ends of both the servo electric cylinder and the servo air cylinder are fixedly connected to the main saw module and are used to drive the main saw module to move up and down reciprocally. The servo electric cylinder is a non-self-locking cylinder, and the servo air cylinder is equipped with a fast exhaust valve. The main saw device has a roughing state and a finishing state. When the main saw device is in the roughing state, the servo air cylinder is activated, and the servo electric cylinder is not activated. When the main saw device is in the finishing state, the servo electric cylinder is activated, and the servo air cylinder is not activated.

[0006] As a preferred embodiment, the main saw module includes a main saw frame, a saw wheel, a first lifting slide plate, a second lifting slide plate, and a main saw drive motor. The top of the main saw frame has a saw blade mounting slot. The saw wheel is rotatably mounted on the saw blade mounting slot via a transmission shaft. The main saw frame is fixedly mounted on the first lifting slide plate. One end of the transmission shaft passes sequentially through the main saw frame and the first lifting slide plate, and a main saw driven gear is mounted thereon. The second lifting slide plate is fixed to the side of the first lifting slide plate away from the main saw and located below the main saw driven gear. Both lifting slide plate one and lifting slide plate two are slidably mounted on the support frame. The main saw drive motor is located between the servo electric cylinder and the servo air cylinder and is fixed on the lifting slide plate two. The transmission end of the main saw drive motor passes through the lifting slide plate two and is equipped with the main saw drive gear. The main saw drive gear is located between the lifting slide plate one and the lifting slide plate two. The main saw drive gear is connected to the main saw driven gear through a synchronous toothed belt. The transmission end of the servo electric cylinder is connected to the lifting slide plate one, and the transmission end of the servo air cylinder is connected to the lifting slide plate two.

[0007] As a preferred embodiment, the servo electric cylinder drive end is connected to the first lifting slide plate via an electric cylinder connecting plate, and the servo air cylinder drive end is connected to the second lifting slide plate via an air cylinder connecting plate.

[0008] As a preferred embodiment, a baffle is also provided on the outer periphery of the saw blade mounting groove, and the baffle is fixedly installed on the main saw blade frame.

[0009] As a preferred embodiment, multiple equidistant limiting arc blocks are fixedly installed on both sides of the support frame. A longitudinally arranged connecting guide rod is fitted onto each limiting arc block. The first lifting slide plate is fixedly connected to the second lifting slide plate via a linear bearing block. The linear bearing block is located between two adjacent limiting arc blocks. The linear bearing block is installed through the connecting guide rod and slidably connected to the connecting guide rod. The main saw drive motor is fixed on the side of the second lifting slide plate away from the first lifting slide plate.

[0010] As a preferred embodiment, the second lifting slide plate includes a first plate and a second plate. Both the first plate and the second plate are fixedly connected to the first lifting sliding plate via the linear bearing block. The first plate is connected to the second plate via a main saw drive mounting plate. The main saw drive motor is fixedly mounted on the main saw drive mounting plate. The main saw drive mounting plate has clearance through holes corresponding to the transmission end of the main saw drive motor.

[0011] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly improves the overall performance of the main saw device by using a dual power source collaborative architecture of servo electric cylinder and servo air cylinder, combined with a non-self-locking electric cylinder structure and a fast exhaust valve design. In the roughing stage, the fast response characteristics of the servo air cylinder are used to reduce energy consumption and improve lifting efficiency. In the finishing stage, the precision positioning control of the servo electric cylinder is used to improve the machining accuracy. At the same time, the fast exhaust valve can effectively eliminate the interference of residual pressure of the servo air cylinder on the servo electric cylinder, thus achieving a dynamic balance between machining accuracy, efficiency and energy consumption.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0025] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0026] Please see Figures 1 to 4 This utility model provides a servo-positioned main saw device, including a support frame 10, a main saw module 20, a servo electric cylinder 30, and a servo air cylinder 40. The main saw module 20 is longitudinally slidably mounted on the support frame 10. The servo electric cylinder 30 is fixed to one side of the support frame 10, and the servo air cylinder 40 is fixed to the side of the support frame 10 away from the servo electric cylinder 30. The transmission ends of both the servo electric cylinder 30 and the servo air cylinder 40 are fixedly connected to the main saw module 20 and are both used to drive the main saw module 20 to move up and down reciprocally. The dual power source setting is to meet the lifting and feeding requirements under different processing states. The servo electric cylinder 30 is a non-self-locking electric cylinder, and the servo air cylinder 40 is equipped with a fast exhaust valve 41. The main saw device has a roughing state and a finishing state. When the main saw device is in the roughing state, the servo air cylinder 40 is activated, and the servo electric cylinder 30 is not activated. When the main saw device is in the finishing state, the servo electric cylinder 30 is activated, and the servo air cylinder 40 is not activated.

[0027] Specifically, in the roughing stage, the requirements for machining accuracy are relatively low, but the requirements for speed are high. The servo cylinder 40 responds quickly, driving the main saw module 20 to move up and down rapidly. At this time, the servo electric cylinder 30 does not participate in the work to save energy. In the finishing stage, the requirements for machining accuracy are high. The servo electric cylinder 30 provides precise lifting control to ensure machining accuracy. At this time, the servo cylinder 40 does not participate in the work to avoid interfering with the precise control of the servo electric cylinder 30.

[0028] It should also be noted that the non-self-locking design means that when the servo cylinder 30 is powered off or de-energized, i.e. when the main saw is in the roughing state and the servo cylinder 30 is not moving, it will not lock to maintain its current position, thus ensuring that the servo cylinder 40 can work normally. The fast exhaust valve 41 can quickly release the gas in the servo cylinder 40. When the main saw is in the finishing state, it avoids generating unnecessary lifting resistance on the servo cylinder 30, which would interfere with the control accuracy.

[0029] In this embodiment, the main saw module 20 includes a main saw frame 21, a saw wheel 22, a first lifting slide plate 23, a second lifting slide plate 24, and a main saw drive motor 25. The top of the main saw frame 21 has a saw blade mounting groove 211, which provides a stable mounting position for the saw wheel 22, ensuring smooth operation. The saw wheel 22 is rotatably mounted on the saw blade mounting groove 211 via a transmission shaft 26, which enables the rotation of the saw wheel 22 and provides power for the cutting operation. The main saw frame 21 is fixedly mounted on the first lifting slide plate 23, and the main saw frame 21 and the first lifting slide plate 23 are fixedly connected to ensure synchronous movement. One end of the transmission shaft 26 passes sequentially through the main saw frame 21 and the first lifting slide plate 23 and is fitted with a main saw driven gear 261, which serves as a transmission component to transmit power to the saw wheel 22. The second lifting slide plate 24 is fixed on the side of the first lifting slide plate 23 away from the main saw blade and located below the main saw driven gear 261. The second lifting slide plate 24 cooperates with the first lifting slide plate 23 to provide stable lifting support for the main saw module 20, and its location below the main saw driven gear 261 facilitates transmission connection. Both the first lifting slide plate 23 and the second lifting slide plate 24 are slidably mounted on the support frame 10, enabling smooth lifting and lowering of the main saw module 20 on the support frame 10. The main saw drive motor 25 is located between the servo electric cylinder 30 and the servo air cylinder 40 and is fixed on the second lifting slide plate 24 to ensure stable power transmission. The transmission end of the main saw drive motor 25 passes through the second lifting slide plate 24 and is equipped with the main saw drive gear 251. The main saw drive gear 251 is located between the first lifting slide plate 23 and the second lifting slide plate 24, facilitating transmission connection with the main saw driven gear 261. The main saw drive gear 251 is connected to the main saw driven gear 261 via a synchronous toothed belt 27, realizing power transmission between the main saw drive gear 251 and the main saw driven gear 261, ensuring the stable rotation of the saw wheel 22. The drive end of the servo electric cylinder 30 is connected to the lifting plate 1 23, realizing precise control of the lifting of the main saw module 20. The drive end of the servo cylinder 40 is connected to the lifting plate 24, providing power support for the rapid lifting of the main saw module 20.

[0030] Furthermore, the transmission end of the servo electric cylinder 30 is connected to the lifting slide plate 23 via the electric cylinder connecting plate 31. The electric cylinder connecting plate 31, acting as an intermediate connector, enhances the stability and reliability of the connection between the servo electric cylinder 30 and the lifting slide plate 23, ensuring efficient power transmission. The transmission end of the servo cylinder 40 is connected to the lifting slide plate 24 via the cylinder connecting plate 42. The cylinder connecting plate 42 also serves as a stable connection, enabling the servo cylinder 40 to accurately drive the lifting slide plate 24 to perform lifting movements.

[0031] A baffle 212 is also provided on the outer periphery of the saw blade mounting groove 211. The baffle 212 is fixedly installed on the main saw blade frame 21. The baffle 212 effectively prevents the flying of cutting debris.

[0032] Multiple equally spaced limiting arc blocks 11 are fixedly installed on both sides of the support frame 10. A longitudinally arranged connecting guide rod 12 is fitted onto each limiting arc block 11. The longitudinal arrangement of the connecting guide rod 12 provides a precise track for the sliding of the first lifting slide plate 23 and the second lifting slide plate 24, further improving the lifting accuracy. Specifically, the first lifting slide plate 23 is fixedly connected to the second lifting slide plate 24 via a linear bearing block 50. The linear bearing block 50 is located between two adjacent limiting arc blocks 11 and is installed through the connecting guide rod 12, sliding in a slidable manner. Through this installation and sliding connection, the linear bearing block 50 can slide precisely along the connecting guide rod 12, thereby driving the first lifting slide plate 23 and the second lifting slide plate 24 to perform stable lifting movements. The main saw drive motor 25 is fixed on the side of the second lifting slide plate 24 away from the first lifting slide plate 23, ensuring smooth power transmission and avoiding interference with other components, thus ensuring the overall compactness and efficiency of the equipment.

[0033] It should also be clarified that the linear bearing block 50 not only achieves a fixed connection between the lifting slide plate 1 23 and the lifting slide plate 24, but also reduces friction during sliding and improves the smoothness of sliding through its internal bearing structure. The linear bearing block 50 is reasonably arranged between adjacent limiting arc blocks 11, making full use of space and ensuring the stability of the lifting slide plate 1 23 and the lifting slide plate 24 during sliding.

[0034] Furthermore, the lifting slide plate 24 includes a first plate 241 and a second plate 242. This split design facilitates manufacturing, installation, debugging, and subsequent maintenance. Both the first plate 241 and the second plate 242 are fixedly connected to the lifting sliding plate 1 via linear bearing blocks 50. The linear bearing blocks 50 ensure a stable connection between the first plate 241, the second plate 242, and the lifting slide plate 23, ensuring that the three can move synchronously and smoothly. The first plate 241 is connected to the second plate 242 via the main saw drive mounting plate 60. The main saw drive mounting plate 60, as a connecting component, not only strengthens the connection between the first plate 241 and the second plate 242 but also provides a stable mounting base for the main saw drive motor 25. That is, the main saw drive motor 25 is fixedly mounted on the main saw drive mounting plate 60, ensuring the stability of the motor during operation and facilitating the effective transmission of power. The main saw drive mounting plate 60 has a clearance through hole 61 corresponding to the transmission end of the main saw drive motor 25. The clearance through hole 61 avoids interference between the transmission end of the main saw drive motor 25 and the main saw drive mounting plate 60, ensuring smooth and unobstructed power transmission.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
