[0041] In the industry application of laser cutting processing, the XYZ three-axis cutting machine can meet the demand of planar cutting of materials, and in order to facilitate subsequent welding of the cut materials and meet other needs, a swing shaft mechanism needs to be installed between the power output end of the three-axis machine and the laser cutting head to realize the function of bevel cutting. In the process of planar cutting, the axis of the cutting head is perpendicular to the material plane. In the process of bevel cutting, the axis of the cutting head is less than 90° with the cutting intersection angle of the material plane.
[0042] The swing shaft mechanism is a supporting mechanism composed of two mutually perpendicular rotating shafts, which can rotate the cutting head to different postures to meet the needs of bevel cutting. Common swing shaft mechanisms that can realize bevel cutting include AB swing shaft, BC swing shaft, etc. The AB swing shaft is mainly composed of a B-axis seat, a B-axis motor (and a reducer), an A-axis seat, an A-axis motor (and a reducer), a cutting head mounting plate and the like, which are installed in series, and the cutting head is mounted on the cutting head mounting plate. The B-axis seat is vertically installed on the base moving along the Z-axis. The nozzle center of the cutting head is usually a certain distance away from the vertically arranged base to obtain sufficient activity 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: in the common laser cutting machine, the feeding direction is +Y axis, the vertical upward direction perpendicular to the cutting plane is +Z axis, and then the X axis is defined according to the right-hand coordinate system. Swing shaft A axis: the rotating shaft that rotates around the X axis of the machine. Swing shaft B axis: the rotating shaft that rotates around the Y axis of the machine. Swing shaft C axis: the rotating shaft that rotates around the Z axis of the machine.
[0043] Due to the installation of the swing shaft mechanism, when planar cutting is performed, the cutting processing effect will be significantly reduced compared to not installing the swing shaft mechanism.
[0044] As Figure 1 and Figure 2As shown, the embodiment provides a machining device, which comprises a machine tool and a swing shaft mechanism. The base 100 is the output terminal of the machine tool transmission system, and is used to install the swing shaft mechanism. The machine tool drives the swing shaft mechanism to move at least in the X, Y and Z directions, so as to drive the machining head 1000 to perform planar cutting and bevel cutting on the material on the workbench.
[0045] The swing shaft mechanism is used to install the machining head 1000, and comprises the base 100, a displacement driving assembly 200, a first driving assembly 310 and a second driving assembly 320. The displacement driving assembly 200 comprises a displacement output shaft 231 extending in a first direction, and the end of the displacement output shaft 231 forms a displacement output end. The first driving assembly 310 has a first output shaft 3131 extending in a second direction and capable of rotating around its own axis. The first driving assembly 310 is arranged at the displacement output end. The second driving assembly 320 has a second output shaft 3231 extending in a third direction and capable of rotating around its own axis. The second driving assembly 320 is arranged at the first output end of the first output shaft 3131. The machining head 1000 is arranged at the second output end of the second output shaft 3231. The displacement output end is capable of moving to drive the first driving assembly 310 to move and / or rotate between a first position and a second position, and to drive the second output end to move close to or away from the base 100.
[0046] The above arrangement makes the machining head 1000 have two working states. In the first working state, it is suitable for bevel cutting function, and in the second working state, it is suitable for planar cutting function. In the first working state, i.e. when bevel cutting is performed, the second output end is driven by the displacement driving part 210 to move away from the base 100, so as to facilitate the adjustment of the angle of the machining head 1000 by the first driving part 312 and the second driving part 322 to adapt to the angle requirement in bevel cutting. In the second working state, i.e. when planar cutting is performed, the second output end is driven by the displacement driving part 210 to move close to the base 100, which improves the end positioning and machining precision of the machining head 1000. The reason is that the center of gravity of the machining head 1000 is close to the base 100, the force arm between the machining head 1000 and the base 100 is shortened, the deformation of the swing shaft mechanism itself is reduced, the inertia moment of the transmission mechanism of the base 100 is reduced, the load is reduced, the deformation of the mechanical structure is weakened, the control error is reduced, and the end positioning and machining precision of the machining head 1000 are improved. In addition, after the machining head 1000 moves close to the base 100, the distance between the machining head end 1100 and the transmission mechanism is shortened, which suppresses the amplification effect of the deformation of the transmission mechanism when it is transmitted to the machining head end 1100, and further improves the end positioning and machining precision of the machining head 1000.
[0047] In some embodiments, the variable displacement output shaft 231 can rotate around its own axis, the first direction is parallel to the third direction; the variable displacement output shaft 231 can rotate between a first angle and a second angle, when the variable displacement output shaft 231 is at the first angle, the distance between the second output end and the base 100 is a first distance, when the variable displacement output shaft 231 is at the second angle, the distance between the second output end and the base 100 is a second distance, the first distance is greater than the second distance. In use, when the variable displacement output shaft 231 rotates to the first angle, the machining head 1000 is in the first working state; when the variable displacement output shaft 231 rotates to the second angle, the machining head 1000 is in the second working state. Wherein the variable displacement driving part 210 is a servo motor.
[0048] Exemplarily, the first direction and the third direction are both X direction, the second direction and the third direction are perpendicular. When the variable displacement output shaft 231 is at the first angle, the first output shaft 3131 extends along the Y direction. When the variable 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 directly above the variable displacement output shaft 231. When the machining head 1000 is in the second working state, the variable displacement output shaft 231 is at the second angle, and the first output shaft 3131 extends along the Z direction, wherein the distance between the base 100 and the machining head 1000 in the Y direction is the smallest, which maximizes the end positioning and machining precision of the machining head 1000.
[0049] In some embodiments, the second output shaft 3231 and the variable displacement output shaft 231 always remain parallel, and at the same time, are parallel to the plane to be machined of the material respectively, wherein the angle between the second output shaft 3231 and the first output shaft 3131 is always equal to the angle between the variable displacement output shaft 231 and the first output shaft 3131.
[0050] When machining the 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, and during the process of the displacement output shaft 231 rotating 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; and when the displacement output shaft 231 is at the second angle, the machining head end 1100 at the lowermost end of the machining head 1000 is convenient for machining the plane, at this time, the force arm between the machining head end 1100 of the machining head 1000 and the base 100 is the smallest, which improves 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 needs the displacement output shaft 231 and the second output shaft 3231 to act cooperatively. Specifically, the machining head 1000 needs to be adjusted from the first working state to the second working state, which needs the displacement output shaft 231 to rotate-90° around the X direction, and the second output shaft 3231 to rotate+90° around the X direction. In other words, in combination with the above description, 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 machining head end 1100 is close to the base 100 from the upper end. Figure 1 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 machining head end 1100 is close to the base 100 from the upper end.
[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 above arrangement of the position of the machining head end 1100 makes the movable range of the machining head 1000 larger, and the machining range larger, and during the process of cutting the plane, the machining head end 1100 will not be affected by the base 100.
[0052] It can be understood that in this embodiment, the position of the machining 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, so as long as it is ensured that the machining head end 1100 will not be affected by the base 100 during the process of cutting the plane when the displacement output shaft 231 is at the second angle; then when the displacement output shaft 231 is at the first angle for bevel cutting, the machining head end 1100 of the machining head 1000 is also lower than the base 100, and the machining head end 1100 will not be affected by the base 100 during the machining process.
[0053] In addition, 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, a larger space is provided for angle adjustment of the machining head 1000, avoiding interference with the base 100 and the swing shaft mechanism itself during the adjustment process.
[0054] The displacement driving assembly 200 further comprises a displacement driving member 210, a displacement support 220 and a displacement reducer 230. The displacement support 220 is arranged on the base 100, the displacement driving member 210 is arranged on the displacement support 220, the input end of the displacement reducer 230 is connected with the output end of the displacement driving member 210, and the output end of the displacement reducer 230 forms the displacement output end of the displacement output shaft 231. The arrangement of the reducer improves the rotation accuracy and torque of the displacement output shaft 231, so as to adapt to higher machining accuracy requirements.
[0055] For ease of assembly, in some embodiments, the displacement support 220 comprises a displacement bottom plate 221 and a displacement mounting plate 222. The displacement bottom 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 bottom plate 221, and the displacement reducer 230 and the displacement driving member 210 are both fixed on the displacement mounting plate 222. The displacement mounting plate 222 penetrates an installation passage, part of the displacement reducer 230 is located in the installation passage, and part of the displacement driving member 210 is located in the installation passage. The above arrangement, under the premise of driving the first driving assembly 310 to rotate, reduces the cantilever structure, helps to improve the stability, and improves the 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 support 220 in the X direction is as small as possible, the stability of the machining head 1000 is improved, and thus the machining accuracy is improved. The installation passage comprises a first passage and a second passage connected in communication. The diameter of the first passage is greater than the diameter of the second passage. Part of the displacement reducer 230 is located in the first passage and abuts against the step surface between the first passage and the second passage. Part of the displacement driving member 210 is located in the second passage.
[0056] In some embodiments, in order to improve the stability of the displacement driving member 210, the displacement support 220 comprises a first support part and a second support part. The first support part and the second support part are arranged in a third direction. The displacement driving member 210 is connected to the first support part and the second support part. The first support part and the second support part are both mounting holes. The displacement driving member 210 is arranged in the two mounting holes.
[0057] In other embodiments, the displacement driving assembly 200 is a folding mechanism or a telescopic mechanism, and the displacement output end can be close to or away from the base 100. The folding mechanism is similar to a scissor jacking mechanism, and the telescopic mechanism can be a pneumatic cylinder, a hydraulic cylinder or an electric push rod.
[0058] The first driving assembly 310 comprises a first support 311, a first driving member 312 and a first speed reducer 313. The first support 311 is arranged on the displacement output shaft 231. The first driving member 312 is arranged on the first support 311. The first speed reducer 313 is arranged on the first support 311 and is in transmission connection with the output end of the first driving member 312. The output shaft of the first speed reducer 313 forms a first output shaft 3131. The second driving assembly 320 is arranged on the first output shaft 3131. The first driving member 312 is a servo motor. The first support 311 is L-shaped.
[0059] The second driving assembly 320 comprises a second support 321, a second driving member 322 and a second speed reducer 323. The second support 321 is arranged on the first output shaft 3131. The second driving member 322 is arranged on the second support 321. The second speed reducer 323 is arranged on the second support 321 and is in transmission connection with the output end of the second driving member 322. The output shaft of the second speed reducer 323 forms a second output shaft 3231. The machining head mounting plate 1200 is arranged on the second output shaft 3231. The machining head 1000 is mounted on the machining head mounting plate 1200. The second driving member 322 is a servo motor. The second support 321 is T-shaped or L-shaped.
[0060] In combination with the bevel angle, the inclination direction of the machining head 1000 needs to be adjusted. In other embodiments, when the displacement output shaft 231 is located 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 output shaft 3131 and the second output shaft 3231 can be larger. When the displacement output shaft 231 is located at the first angle, the rotatable range of the first output shaft 3131 and the second output shaft 3231 can be limited within ±50° when bevel cutting is performed. In fact, the rotation angle capability of the second output shaft 3231 is at least ±90°, so the rotatable capability of the first output shaft 3131 and the second output shaft 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 setting can cut bevels of different angles.
[0062] In other embodiments, the machining head 1000 can also be other material-removing devices (such as a grinding head, a turning head, or a planing head) or material-adding devices (such as a 3D printing head).
[0063] Obviously, the above-mentioned embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments, and replacements can be made without departing from the protection scope of the present application. Here, it is not necessary and also impossible to enumerate all the implementation modes. Any modification, equivalent replacement, and improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
