[0002] Servo swing shear production lines offer advantages such as high precision, high efficiency, and minimal material waste, making them widely used in sheet metal processing. The flying swing shear, as a key component, plays a crucial role in the decomposition of its motion. Existing flying swing shear motion decomposition mechanisms utilize arc-shaped guide rails at both the front and rear, and theoretically, the center of these guide rails must coincide with the center of the equipment. This structure demands high machining precision, and the integrated design at both ends makes replacement cumbersome and costly. Summary of the Invention

[0003] This invention solves the problems of the flying pendulum shear motion decomposition mechanism in related technologies, which uses arc-shaped guide rails at both the front and rear, requiring high machining accuracy, and is troublesome and costly to replace. It proposes a flying pendulum shear follower mechanism, which uses a combination of arc-shaped and linear guide rails at the front end, and a combination of universal coupling, slewing bearing and linear guide rails at the rear end to decompose the X-axis circular motion of the flying pendulum shear, while retaining the rotational motion in the Y-axis direction. The front and rear end structures are separated, reducing the difficulty and cost of replacement. Moreover, the use of universal coupling reduces the requirement for machining accuracy and improves reliability.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a flying pendulum shear follower mechanism, including a frame, the frame being mounted on a first linear guide rail, an arc-shaped guide rail being mounted on the top of the frame via a first roller bearing, and a lower blade holder being connected to both sides of the arc-shaped guide rail; the frame being connected to a crossbeam via a second roller bearing; a universal coupling being rotatably connected to the rear end of the lower blade holder, the universal coupling being rotatably connected to a slewing bearing, the slewing bearing being mounted on a second linear guide rail, and the slewing bearing being connected to a belt via a guide rail groove.

[0005] As a preferred embodiment, the first roller bearing is mounted on the adjusting plate by adjusting bolts.

[0006] As a preferred embodiment, several of the first roller bearings are distributed on both sides of the arc-shaped guide rail.

[0007] As a preferred embodiment, the lower tool holder is placed on the crossbeam and connected to both sides of the arc-shaped guide rail via a connecting seat.

[0008] As a preferred embodiment, the second roller bearing is fixed to the frame, and two mounting plates are installed at the bottom of the crossbeam by screws. The second roller bearing is located between the two mounting plates and can move up and down between the two mounting plates.

[0009] As a preferred embodiment, the mounting plate is equipped with adjusting bolts for adjusting flatness.

[0010] As a preferred embodiment, one end of the universal coupling is connected to the lower tool holder via a rotating shaft, and the other end is connected to the slewing bearing via a rotating shaft.

[0011] As a preferred embodiment, the slewing bearing is mounted on the second linear guide rail via a connecting plate.

[0012] As a preferred embodiment, the belt is connected to the guide rail groove via rollers.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The front end of the present invention adopts a combination of arc-shaped guide rail and linear guide rail, and the rear end adopts a combination of universal coupling, slewing bearing and linear guide rail to decompose the X-axis circular motion of the flying pendulum shear, while retaining the rotational motion in the Y-axis direction.

[0020] 2-Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. 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.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0023] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0024] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0025] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0026] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0027] like Figures 1 to 4 As shown, a flying pendulum shear follower mechanism includes a frame 3, which is mounted on a first linear guide rail 4. The frame 3 can move back and forth horizontally under the action of the first linear guide rail 4. An arc-shaped guide rail 1 is mounted on the top of the frame 3 via a first roller bearing 2. A lower blade holder 11 is connected to both sides of the arc-shaped guide rail 1. The lower blade holder 11 rotates horizontally under the action of gears and rotates in a circular motion in the back and forth direction under the drive of a motor. The arc-shaped guide rail 1 rotates with the rotation axis of the lower blade holder 11 as its center, thereby decomposing the lower blade holder 11. The circular motion causes it to move in the front-to-back direction and also has a rotational motion. The frame 3 is connected to the crossbeam 6 through the second roller bearing 5, which can decompose the rotational motion of the crossbeam 6. The rear end of the lower tool holder 11 is rotatably connected to a universal coupling 7, which is rotatably connected to a slewing bearing 9. The slewing bearing 9 is mounted on the second linear guide rail 8 and moves synchronously with the circular and rotational motion of the lower tool holder 11. The slewing bearing 9 is connected to the belt 13 through the guide rail groove 12, so that as the guide rail groove 12 rotates, each section of the belt 13 can move synchronously.

[0028] In one embodiment, the first roller bearing 5 is mounted on the adjusting plate 502 by adjusting bolt 501. Loosening the adjusting bolt 501 can adjust the concentricity between the arc guide rail 1 and the equipment. After adjustment, tighten the adjusting bolt 501.

[0029] In one embodiment, a plurality of first roller bearings 2 are distributed on both sides of the arc-shaped guide rail 1, thereby clamping the arc-shaped guide rail 1.

[0030] In one embodiment, the lower tool holder 11 is placed on the crossbeam 6 and connected to both sides of the arc-shaped guide rail 1 via the connecting seat 10.

[0031] In one embodiment, the second roller bearing 5 is fixed to the frame 3, and two mounting plates 601 are installed at the bottom of the crossbeam 6 by screws. The second roller bearing 5 is located between the two mounting plates 601 and can move up and down between the two mounting plates 601.

[0032] In one embodiment, adjusting bolts for adjusting flatness are mounted on the mounting plate 601.

[0033] In one embodiment, one end of the universal coupling 7 is connected to the lower tool holder 11 via a rotating shaft, and the other end is connected to the rotary bearing 9 via a rotating shaft.

[0034] In one embodiment, the rotary bearing 9 is mounted on the second linear guide rail 8 via a connecting plate.

[0035] In one embodiment, the belt 13 is connected to the guide rail groove 12 via rollers.

[0036] The above are preferred embodiments of the present invention. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on the present invention are within the protection scope of the present invention.
