[0001] This utility model relates to the field of laser cutting technology, and in particular to a swing shaft mechanism and processing equipment. Background Technology

[0002] In laser cutting applications, three-axis cutting machines can perform planar cutting of materials. Adding a swivel axis mechanism to a three-axis machine enables beveling, facilitating subsequent welding or other processes. The swivel axis mechanism is typically a transmission mechanism consisting of two shafts connected in series, allowing the cutting head to rotate to various positions for beveling.

[0003] After adding the swing axis mechanism, the cutting accuracy of the cutting head of the five-axis cutting machine will be significantly reduced when performing planar cutting compared to when the swing axis mechanism is not installed.

[0004] Therefore, it is urgent to study a swing shaft mechanism and processing equipment to solve the above problems. Utility Model Content

[0010] The second drive assembly has a second output shaft that extends in a third direction and is rotatable about its own axis; the second drive assembly is disposed at the first output end of the first output shaft.

[0012] As an optional technical solution for a swing shaft mechanism, the displacement output shaft can rotate around its own axis, with the first direction parallel to the third direction;

[0013] The displacement output shaft can rotate between a first angle and a second angle. When the displacement output shaft is at the first angle, the distance between the second output end and the base is a first distance. When the displacement output shaft is at the second angle, the distance between the second output end and the base is a second distance. The first distance is greater than the second distance.

[0014] As an optional technical solution for a swing shaft mechanism, the first direction and the third direction are both X directions, and the second direction and the third direction are perpendicular; when the displacement output shaft is at the first angle, the first output shaft extends along the Y direction; when the displacement output shaft is at the second angle, the first output shaft extends along the Z direction, and the second output shaft is located directly above the displacement output shaft.

[0015] As an optional technical solution for the swing shaft mechanism, during the process of the displacement output shaft rotating from the first angle to the second angle, the displacement output shaft and the second output shaft rotate synchronously to drive the machining head to rotate, so that the axis of the machining head always extends along the Z direction.

[0016] As an optional technical solution for the swing shaft mechanism, when the displacement output shaft is at the second angle, the axis of the processing head extends along the Z direction, and the end of the processing head is lower than the base.

[0018] As an optional technical solution for a swing shaft mechanism, the displacement bracket includes a displacement base plate and a displacement mounting plate.

[0023] This utility model has at least the following beneficial effects:

[0024] This invention provides a swing shaft mechanism and a processing device. The swing shaft mechanism is used to mount a processing head and is mounted on a base. The swing shaft mechanism includes a displacement drive assembly, a first drive assembly, and a second drive assembly. The displacement drive assembly includes a displacement output shaft extending along a first direction, with its end forming a displacement output end. The displacement drive assembly is located on the base. The first drive assembly has a first output shaft extending along a second direction and capable of rotating about its own axis. The first drive assembly is located at the displacement output end. The second drive assembly has a second output shaft extending along a third direction and capable of rotating about its own axis. The second drive assembly is located at the first output end of the first output shaft. The processing head is located at the second output end of the second output shaft. The displacement output end can move to drive the first drive assembly to move and / or rotate between a first position and a second position, and to drive the second output end closer to or away from the base. This configuration enables the processing head to have a bevel cutting function and simultaneously possesses an enhanced planar cutting function. In the beveling process, the displacement drive moves the second output end away from the base, facilitating head angle adjustment via the first and second drives. Conversely, in the planar cutting process, the displacement drive moves the second output end closer to the base, improving end-effector positioning and machining accuracy. This is because the center of gravity of the machining head is closer to the base, the lever arm between them is shorter, the deformation of the swing shaft mechanism is reduced, and the inertial torque and load on the base's transmission mechanism decrease. Consequently, mechanical deformation is reduced, control errors are lowered, and end-effector positioning and machining accuracy are improved. Furthermore, the closer the machining head is to the base, the shorter distance between the head end and the transmission mechanism suppresses the amplification of transmission mechanism deformation transmitted to the head end, further enhancing end-effector positioning and machining accuracy.

[0034] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0035] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0036] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0037] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0038] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0039] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0040] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0041] In laser cutting applications, XYZ three-axis cutting machines can meet the needs of planar material cutting. However, to facilitate subsequent welding of the cut materials and meet other requirements, a swing axis mechanism needs to be installed between the power output end of the three-axis machine and the laser cutting head to achieve bevel cutting. During planar cutting, the axis of the cutting head is perpendicular to the material plane. During bevel cutting, the cutting angle between the axis of the cutting head and the material plane is less than 90°.

[0042] The oscillating axis mechanism is a support mechanism composed of two mutually perpendicular rotating axes linked together, which can rotate the cutting head to different postures to meet the needs of bevel cutting. Common oscillating axis mechanisms that can achieve bevel cutting include AB oscillating axis and BC oscillating axis. The AB oscillating axis is mainly composed of B-axis seat, B-axis motor (and reducer), A-axis seat, A-axis motor (and reducer), and cutting head mounting plate, which are installed in series. The cutting head is mounted on the cutting head mounting plate, and the B-axis seat is vertically mounted on the base that moves along the Z-axis. The center of the nozzle of the cutting head is usually a certain distance away from the vertically set base to obtain sufficient movement space, so that the laser cutting head does not interfere when adjusting the bevel cutting posture. Among them, the XYZ axes of the laser cutting machine tool: In common laser cutting machines, the direction along the feeding advance is the +Y axis, the vertical upward direction perpendicular to the cutting plane is the +Z axis, and then the X-axis is defined according to the right-hand coordinate system. Oscillating axis A-axis: The rotating axis that rotates around the X-axis of the machine tool. Oscillating axis B-axis: The rotating axis that rotates around the Y-axis of the machine tool. Oscillating axis C-axis: A rotating axis that rotates around the Z-axis of a machine tool.

[0043] Due to the addition of the swing shaft mechanism, the cutting effect is significantly reduced when performing planar cutting compared to when the swing shaft mechanism is not installed.

[0044] like Figure 1 and Figure 2As shown, this embodiment provides a processing device including a machine tool and a swing axis mechanism. The base 100 is the output terminal of the machine tool's transmission system and is used to mount the swing axis mechanism. The machine tool drives the swing axis mechanism to move in at least the X, Y, and Z directions, thereby driving the processing head 1000 to perform planar cutting and beveling cutting on the material on the worktable.

[0045] The swing shaft mechanism is used to mount the machining head 1000. The swing shaft mechanism includes a base 100, a displacement drive assembly 200, a first drive assembly 310, and a second drive assembly 320. The displacement drive assembly 200 includes a displacement output shaft 231 extending along a first direction, with the end of the displacement output shaft 231 forming a displacement output end. The first drive assembly 310 has a first output shaft 3131 extending along a second direction and rotatable about its own axis. The first drive assembly 310 is located at the displacement output end. The second drive assembly 320 has a second output shaft 3231 extending along a third direction and rotatable about its own axis. The second drive assembly 320 is located at the first output end of the first output shaft 3131. The machining head 1000 is located at the second output end of the second output shaft 3231. The displacement output end can be actuated to drive the first drive assembly 310 to move and / or rotate between a first position and a second position, and to drive the second output end closer to or away from the base 100.

[0046] The above configuration allows the machining head 1000 to have two working states: a first working state suitable for beveling cutting and a second working state suitable for planar cutting. In the first working state, i.e., when performing beveling cutting, the displacement drive 210 moves the second output end away from the base 100, facilitating the adjustment of the machining head 1000's angle using the first drive 312 and the second drive 322 to meet the angle requirements of beveling cutting. In the second working state, i.e., when performing planar cutting, the displacement drive 210 moves the second output end closer to the base 100, improving the end-positioning and machining accuracy of the machining head 1000. This is because the center of gravity of the machining head 1000 is closer to the base 100, increasing its accuracy. The lever arm between the machining head 1000 and the base 100 is shortened, the deformation of the swing shaft mechanism itself is reduced, and the inertial torque and load on the transmission mechanism of the base 100 are reduced. Consequently, the deformation of the mechanical structure is weakened and the control error is reduced, which improves the end positioning and machining accuracy of the machining head 1000. In addition, after the machining head 1000 is close to the base 100, the distance between the end of the machining head 1100 and the transmission mechanism is shortened, which suppresses the amplified effect when the deformation of the transmission mechanism is transmitted to the end of the machining head 1100, further effectively improving the end positioning and machining accuracy of the machining head 1000.

[0047] In some embodiments, the displacement output shaft 231 can rotate about its own axis, with the first direction parallel to the third direction; the displacement output shaft 231 can rotate between a first angle and a second angle. When the displacement output shaft 231 is at the first angle, the distance between the second output end and the base 100 is the first distance; when the displacement output shaft 231 is at the second angle, the distance between the second output end and the base 100 is the second distance, and the first distance is greater than the second distance. In use, when the displacement output shaft 231 rotates to the first angle, the processing head 1000 is in a first working state; when the displacement output shaft 231 rotates to the second angle, the processing head 1000 is in a second working state. The displacement drive 210 is a servo motor.

[0048] For example, the first direction and the third direction are both X-directions, and the second direction and the third direction are perpendicular. When the displacement output shaft 231 is at the first angle, the first output shaft 3131 extends along the Y-direction. When the displacement output shaft 231 is at the second angle, the first output shaft 3131 extends along the Z-direction, and the second output shaft 3231 is located directly above the displacement output shaft 231. When the processing head 1000 is in the second working state, the displacement output shaft 231 is at the second angle, and the first output shaft 3131 extends along the Z-direction. In the Y-direction, the distance between the base 100 and the processing head 1000 is minimized, maximizing the end-positioning and processing accuracy of the processing head 1000.

[0049] In some embodiments, the second output shaft 3231 and the displacement output shaft 231 are always kept parallel and are also parallel to the material to be processed plane, wherein the included angle between the second output shaft 3231 and the first output shaft 3131 is always equal to the included angle between the displacement output shaft 231 and the first output shaft 3131.

[0050] When machining a plane, the angle of the machining head 1000 needs to be adjusted so that the axis of the machining head 1000 is perpendicular to the plane to be machined. In this embodiment, the displacement output shaft 231 and the second output shaft 3231 rotate synchronously to drive the machining head 1000 to rotate. During the rotation of the displacement output shaft 231 from the first angle to the second angle, the axis of the machining head 1000 always extends along the Z direction to avoid interference with the base 100 and other components. Furthermore, when the displacement output shaft 231 is at the second angle, the lowermost machining head end 1100 of the machining head 1000 is more convenient for machining the plane. At this time, the lever arm between the machining head end 1100 and the base 100 is minimized, improving the positioning accuracy and machining accuracy of the machining head end 1100. In this state, the displacement output shaft 231, the first output shaft 3131, and the second output shaft 3231 are in the same vertical plane (XZ plane). The machining head 1000 needs to be adjusted from the first working state to the second working state, which requires the coordinated action of the displacement output shaft 231 and the second output shaft 3231. Specifically, for the machining head 1000 to be adjusted from the first working state to the second working state, the displacement output shaft 231 needs to rotate -90° around the X direction, and the second output shaft 3231 needs to rotate +90° around the X direction. In other words, combined with... Figure 1 To switch from the first working state to the second working state, the displacement output shaft 231 needs to rotate 90° clockwise around the X direction, and the second output shaft 3231 needs to rotate 90° counterclockwise around the X direction, so that the end of the processing head 1100 approaches the base 100 from the top.

[0051] When the displacement output shaft 231 is at the second angle, the axis of the machining head 1000 extends along the Z direction, and the machining head end 1100 of the machining head 1000 is lower than the base 100. The orientation arrangement of the machining head end 1100 allows the machining head 1000 to have a larger range of movement and a larger processing range, and it will not be affected by the base 100 during the plane cutting process.

[0052] It is understood that in this embodiment, the position of the processing head end 1100 when the displacement output shaft 231 is at the first angle is lower than the position when the displacement output shaft 231 is at the second angle. Therefore, as long as the displacement output shaft 231 is at the second angle for planar cutting, the processing head end 1100 will not be affected by the base 100 during the processing process; and when the displacement output shaft 231 is at the first angle for beveling, the processing head end 1100 of the processing head 1000 will also be lower than the base 100, and the processing process will not be affected by the base 100.

[0053] Furthermore, when the displacement output shaft 231 is at the first angle, the first output shaft 3131 is horizontally arranged, and the displacement output shaft 231, the first output shaft 3131, and the second output shaft 3231 are in the same horizontal plane (XY plane). In use, this provides a large space for adjusting the angle of the processing head 1000, avoiding interference between the adjustment process and the base 100 and the structure of the swing shaft mechanism itself.

[0054] The displacement drive assembly 200 also includes a displacement drive component 210, a displacement bracket 220, and a displacement reducer 230. The displacement bracket 220 is mounted on the base 100, the displacement drive component 210 is mounted on the displacement bracket 220, and the input end of the displacement reducer 230 is connected to the output end of the displacement drive component 210, with the output end of the displacement reducer 230 forming the displacement output end of the displacement output shaft 231. The reducer improves the rotational accuracy and torque of the displacement output shaft 231 to meet higher precision machining requirements.

[0055] For ease of assembly, in some embodiments, the displacement bracket 220 includes a displacement base plate 221 and a displacement mounting plate 222. The displacement base plate 221 is parallel to the mounting surface of the base 100 and is mounted on the mounting surface. The displacement mounting plate 222 is perpendicular to the displacement base plate 221. The displacement reducer 230 and the displacement drive component 210 are both fixed to the displacement mounting plate 222. The displacement mounting plate 222 has a through mounting channel, in which part of the displacement reducer 230 and part of the displacement drive component 210 are located. This configuration, while driving the first drive assembly 310 to rotate, reduces the cantilever structure, which helps improve stability and positioning accuracy of the machining head 1000. In particular, when the first output shaft 3131 extends along the Z direction, the distance between the machining head 1000 and the displacement bracket 220 is minimized in the X direction, improving the stability of the machining head 1000 and thus improving machining accuracy. The installation channel includes a first channel and a second channel that are connected. The diameter of the first channel is larger than the diameter of the second channel. Part of the displacement reducer 230 is located in the first channel and abuts against the step surface between the first channel and the second channel. Part of the displacement drive 210 is located in the second channel.

[0056] In some embodiments, to improve the stability of the displacement drive 210, the displacement bracket 220 includes a first support portion and a second support portion, which are arranged at intervals along a third direction. The displacement drive 210 is connected to the first support portion and the second support portion. Both the first and second support portions are mounting holes, and the displacement drive 210 passes through both mounting holes.

[0057] In other embodiments, the displacement drive assembly 200 is a folding mechanism or a telescopic mechanism, and the displacement output end can move closer to or further away from the base 100. The folding mechanism is similar to a scissor lift mechanism; the telescopic mechanism can be a cylinder, a hydraulic cylinder, or an electric push rod.

[0058] The first drive assembly 310 includes a first bracket 311, a first drive member 312, and a first reducer 313. The first bracket 311 is mounted on the displacement output shaft 231, the first drive member 312 is mounted on the first bracket 311, and the first reducer 313 is mounted on the first bracket 311 and is drively connected to the output end of the first drive member 312. The output shaft of the first reducer 313 forms the first output shaft 3131. The second drive assembly 320 is mounted on the first output shaft 3131. The first drive member 312 is a servo motor. The first bracket 311 is L-shaped.

[0059] The second drive assembly 320 includes a second bracket 321, a second drive member 322, and a second reducer 323. The second bracket 321 is mounted on the first output shaft 3131, the second drive member 322 is mounted on the second bracket 321, and the second reducer 323 is mounted on the second bracket 321 and is drively connected to the output end of the second drive member 322. The output shaft of the second reducer 323 forms the second output shaft 3231. A processing head mounting plate 1200 is mounted on the second output shaft 3231, and a processing head 1000 is mounted on the processing head mounting plate 1200. The second drive member 322 is a servo motor. The second bracket 321 is T-shaped or L-shaped.

[0060] Depending on the bevel angle, the tilt direction of the processing head 1000 needs to be adjusted. In other embodiments, when the displacement output shaft 231 is at the first angle, the first output shaft 3131 can rotate ±50° around its own axis, and the second output shaft 3231 can rotate ±50° around its own axis. It should be noted that the rotatable range of the first and second output shafts 3131 can be even greater. When the displacement output shaft 231 is at the first angle, during bevel cutting, the rotation range of the first and second output shafts 3131 and 3231 can be limited to ±50°. In fact, the rotation angle capability of the second output shaft 3231 is at least ±90°, so the rotatable capabilities of both the first and second output shafts 3131 and 3231 can exceed 50°.

[0061] In some embodiments, when the displacement output shaft 231 is located at the first angle, one of the second direction and the third direction is the X direction, and the other is the Y direction. Specifically, when the displacement output shaft 231 is located at the first angle, the second direction is the Y direction, and the third direction is the X direction. In other embodiments, when the displacement output shaft 231 is located at the first angle, one of the second direction and the third direction is the Z direction, and the other is the Y direction. The above angle settings can cut bevels at different angles.

[0062] In other embodiments, the processing head 1000 may also be other devices capable of removing material (such as a grinding head, turning head, or planing head) or adding material (such as a 3D printing head).

[0063] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
