Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of engraving machines, in particular to a whole machine multi-axis engraving system. BACKGROUND

[0002] A laser engraving machine is a numerical control equipment that uses a high-energy-density laser beam to perform non-contact processing on the surface of a material. Laser engraving technology is suitable for processing various materials such as metal, plastic, wood, and ceramic due to its high precision and non-contact processing characteristics.

[0003] Existing laser engraving systems are mainly divided into two categories: one is a two-axis (X-Y) engraving machine based on a mechanical motion frame, which drives the laser to perform planar engraving through a physical slide rail; the other is a two-axis engraving machine using optical galvanometer technology, which uses a rotating mirror to realize rapid deflection of the light beam in the X-Y direction.

[0004] In view of the related art, the amplitude of the optical galvanometer is small, making it difficult to process large-scale engraved objects; and the frame-type laser engraving machine can generally only be used for planar engraving, making it difficult to perform three-dimensional engraving. CONTENT OF THE INVENTION

[0005] In order to be able to perform three-dimensional engraving on an object, the present application provides a whole machine multi-axis engraving system.

[0006] The present application provides a whole machine multi-axis engraving system, which adopts the following technical solution:

[0007] A whole machine multi-axis engraving system, comprising an x-axis slide rail, a y-axis slide rail, a placement table, a mounting frame, a z-axis slide rail, and a laser head, the y-axis slide rail being slidingly arranged on the x-axis slide rail, the placement table being slidingly arranged on the y-axis slide rail, the z-axis slide rail being suspended above the placement table through the mounting frame, the laser head being slidingly arranged on the z-axis slide rail, and an up-down control assembly being arranged on the z-axis slide rail for controlling the up-down sliding of the laser head.

[0008] A first sliding seat is slidingly arranged on the x-axis slide rail along the length direction thereof, the y-axis slide rail is rotatably arranged on the first sliding seat, and a fixing member is arranged on the y-axis slide rail, the fixing member being capable of limiting the rotation of the y-axis slide rail when the y-axis slide rail is rotated to be perpendicular to the x-axis slide rail in a horizontal projection.

[0009] Universal wheels are arranged at both ends of the y-axis slide rail, and when the y-axis slide rail is rotated to be parallel to the x-axis slide rail, the two universal wheels are slidingly arranged at both ends of the x-axis slide rail.

[0010] By adopting the above technical solutions, the multi-axis engraving system can achieve precise engraving operations in three-dimensional space. Through the cooperation of the x-axis, y-axis, and z-axis slide rails, combined with the up-and-down sliding setting of the laser head, precise positioning of the workpiece in three-dimensional space is achieved, overcoming the limitation of traditional planar engraving machines that can only perform two-dimensional processing. Furthermore, the cooperation of the x-axis and y-axis slide rails greatly increases the range of movement in two-dimensional space, improving engraving adaptability. The y-axis slide rail can rotate on the first sliding seat and be locked at a specific angle by a fixing component, allowing the engraving system to quickly switch between working mode and storage mode. The y-axis slide rail can rotate to a state parallel to the x-axis slide rail, reducing its size and facilitating storage. The inclusion of casters not only facilitates the rotation of the y-axis slide rail but also provides support, improving the stability of the equipment.

[0011] Optionally, the up-down control assembly includes a first motor, a screw, and a guide rod disposed within the z-axis slide rail. The screw is rotatably disposed within the z-axis slide rail and is connected to the output end of the first motor. The guide rod is disposed parallel to the screw. A third sliding seat is slidably disposed on the z-axis slide rail along its own length direction. The laser head is disposed on the third sliding seat. The screw is threaded through the third sliding seat, and the guide rod slides through the third sliding seat.

[0012] By adopting the above technical solution, the first motor drives the screw to rotate, and the threaded connection between the screw and the third sliding seat enables the laser head to be accurately positioned along the z-axis. At the same time, the guide rod effectively prevents the third sliding seat from rotating during movement, thereby ensuring that the movement trajectory of the laser head is stable and reliable, and improving the engraving accuracy and processing quality.

[0013] Optionally, the first sliding seat is provided with a first connecting shaft, the y-axis slide rail is rotatably connected to the first connecting shaft, the first connecting shaft has a fixing hole on its side wall, the fixing member includes a handle and a fixing rod connected to each other, the end of the fixing rod is provided with an external thread, when the y-axis slide rail slides to be perpendicular to the x-axis slide rail, the fixing rod can pass through the y-axis slide rail and be threadedly connected to the fixing hole.

[0014] By adopting the above technical solution, the multi-axis engraving system can achieve angle adjustment and fixation of the Y-axis slide rail relative to the X-axis slide rail. Specifically, the design of the first connecting shaft allows the Y-axis slide rail to rotate around it, thus facilitating the retraction of the X-axis and Y-axis slide rails; while the fixing component ensures that when the Y-axis slide rail is adjusted to be perpendicular to the X-axis slide rail, i.e., in the working state, the Y-axis slide rail is securely locked in this position by the handle and the threaded fixing rod, preventing accidental rotation and thus improving engraving accuracy and operational stability.

[0015] Optionally, a flip adjustment component is also included. A second sliding seat is slidably disposed on the y-axis slide rail along its own length direction. The flip adjustment component includes a positioning seat detachably disposed on the second sliding seat, a rotating seat rotatably disposed on the positioning seat, and a second motor for driving the rotating seat to rotate. The output shaft of the second motor is connected to the rotating seat, and the platform is detachably disposed on the rotating seat.

[0016] By adopting the above technical solution, the tilting adjustment component enables the worktable to tilt around a specific axis, thereby meeting the multi-angle processing requirements of the workpiece. The cooperative design of the positioning seat and the rotating seat ensures the stability of the worktable during the tilting process; the method of driving the rotating seat with a second motor achieves precise control of the tilting angle of the worktable, improving processing accuracy and efficiency.

[0017] Optionally, it also includes a support assembly for supporting the shelf, the support assembly including a first support rod, a second support rod, a positioning rod and a first limiting member, the length direction of the second motor output shaft is parallel to the length direction of the y-axis slide rail, the side wall of the x-axis slide rail is provided with a positioning groove along its own length direction, one end of the positioning rod is disposed on the side wall of the first support rod, the other end of the positioning rod is slidably inserted into the positioning groove, the lower end of the second support rod is slidably inserted into the first support rod, the upper end of the second support rod is rotatably connected to the shelf, and the first limiting member can restrict the second support rod from sliding up and down within the first support rod.

[0018] By adopting the above technical solutions, the platform can achieve stable support and adjustment in multiple directions. Specifically, the design of the support components ensures that the platform maintains good stability in different processing positions. Especially when the platform is flipped, the cooperation of the first and second support rods effectively distributes the load, preventing structural instability caused by center of gravity shift. Simultaneously, the sliding insertion structure of the positioning rod and positioning groove, combined with the limiting function of the first limiting component on the second support rod, not only improves the flexibility of the support system but also ensures precise positioning of the platform in any processing posture, thus providing a more reliable processing platform for laser engraving.

[0019] Optionally, a first limiting hole is provided on the side wall of the first support rod, and a plurality of second limiting holes are provided at intervals along the vertical direction on the side wall of the second support rod. The first limiting component includes a first cylinder, a connecting rod, and a first limiting rod. The first cylinder is disposed on the positioning seat, and the first limiting rod is connected to the telescopic shaft of the first cylinder through the connecting rod. The first cylinder can drive the first limiting rod to pass through the first limiting hole and the second limiting hole in sequence. The first limiting hole and the second limiting hole are both oblong holes, and their extension direction is parallel to the length direction of the x-axis slide rail.

[0020] By adopting the above technical solution, the first cylinder can drive the first limiting rod to pass through the first limiting hole and the second limiting hole in sequence, thereby achieving precise locking of the second support rod in the up-and-down sliding position within the first support rod.

[0021] Optionally, multiple sets of the first support rod, the second support rod, and the positioning rod are arranged along the circumference of the platform. Positioning grooves are provided on the two parallel side walls of the x-axis slide rail. Multiple sets of positioning rods are arranged in one-to-one correspondence with the first support rod. The first cylinder can control all the positioning rods to pass through the corresponding first limiting holes.

[0022] By adopting the above technical solution, multiple sets of the first support rod, the second support rod, and the positioning rod are arranged along the circumference of the platform, which can enhance the support stability of the platform and prevent the workpiece from tilting or shaking due to uneven force during the engraving process.

[0023] Optionally, it also includes a rotation adjustment component. The platform includes a mounting outer frame and a rotating inner plate. The mounting outer frame is disposed on the rotating seat, and the rotating inner plate is rotatably disposed within the mounting outer frame. The rotation adjustment component controls the rotating inner plate to rotate within the mounting outer frame.

[0024] By adopting the above technical solution, the multi-axis engraving system can achieve workpiece rotation adjustment within the platform plane, thereby expanding the angle range of laser engraving. Specifically, the design of the mounting frame and the rotating inner plate allows the workpiece placed on the platform to rotate around the vertical axis, enhancing the system's flexibility and adaptability, making it suitable for engraving workpieces with complex shapes or requiring multi-angle processing.

[0025] Optionally, the rotation adjustment assembly includes a power component for driving the inner rotating plate to rotate, the power component being a third motor, and the output shaft of the third motor being coaxially connected to the inner rotating plate.

[0026] By adopting the above technical solution, precise rotation control of the inner rotating plate on the platform relative to the mounting frame is achieved. The third motor, as the power source, has its output shaft coaxially connected to the inner rotating plate, directly driving its rotation and thus adjusting the angle and position of the workpiece placed on it. This design enables the engraving system to perform multi-angle engraving on workpieces, improving engraving accuracy and flexibility, and is particularly suitable for engraving complex curved surfaces or three-dimensional structures.

[0027] Optionally, the rotation adjustment assembly further includes a second limiting member for limiting the rotation of the inner rotating plate. The second limiting member includes a second cylinder disposed on the rotating seat and a second limiting rod connected to the telescopic shaft of the second cylinder. The length direction of the second limiting rod is parallel to the axial direction of the output shaft of the third motor. The mounting frame is provided with a third limiting hole, and the bottom wall of the inner rotating plate is provided with a plurality of fourth limiting grooves in the circumferential direction. The second limiting rod can pass through the third limiting hole and be inserted into the fourth limiting groove.

[0028] By adopting the above technical solution, precise positioning and locking of the rotating inner plate can be achieved during laser engraving. Specifically, when the workpiece angle needs to be adjusted, the second cylinder can drive the second limiting rod to retract from the fourth limiting groove, thereby releasing the restriction on the rotating inner plate and allowing it to rotate freely under the drive of the third motor. After adjusting to the target angle, the second cylinder actuates again, pushing the second limiting rod through the third limiting hole and inserting it into the corresponding fourth limiting groove, thus reliably fixing the rotating inner plate and ensuring stability and accuracy during the engraving process. This design not only improves the flexibility of workpiece processing but also effectively avoids processing errors caused by accidental movement of the rotating inner plate.

[0029] In summary, this application includes at least one of the following beneficial effects:

[0030] 1. By setting up x-axis, y-axis, and z-axis slide rails, and in conjunction with the up-and-down sliding function of the laser head, precise engraving in three-dimensional space is achieved, solving the problem that traditional frame-type laser engraving machines are limited to planar engraving and meeting the needs of three-dimensional engraving;

[0031] 2. The introduction of the flip adjustment component enables the worktable to be flipped for processing, further improving the equipment's adaptability to complex-shaped workpieces and significantly enhancing the flexibility and precision of engraving.

[0032] 3. The design of the rotation adjustment component allows the inner plate to rotate in a controlled manner within the mounting frame. Precise angle adjustment is achieved through a third motor drive, and unnecessary rotation is effectively limited by a second limiting component, thereby ensuring the stability and controllability of the workpiece posture during the engraving process.

[0044] The following is in conjunction with the appendix Figures 1-10 This application will be described in further detail.

[0045] Example 1:

[0046] This application discloses a multi-axis engraving system for an entire machine. (Refer to...) Figure 1 and Figure 2 The engraving system includes an x-axis slide rail 1, a y-axis slide rail 2, a stage 3, a mounting bracket 4, a z-axis slide rail 5, and a laser head 6. The x-axis slide rail 1 has a first sliding seat 11 that slides along its length. The y-axis slide rail 2 is detachably fixed to the first sliding seat 11 by bolts or other means. The y-axis slide rail 2 has a second sliding seat 23 that slides along its length. The stage 3 is also detachably fixed to the second sliding seat 23 by bolts or other means. The upper surface of the stage 3 can be grooved to accommodate a snap-fit ​​structure for securing the workpiece and improving stability during processing. The z-axis slide rail 5 is suspended above the stage 3 via the mounting bracket 4. The mounting bracket 4 can also raise the height of the laser head 6 to accommodate the x-axis slide rail 1 and y-axis slide rail 2 below. The laser head 6 slides vertically on the z-axis slide rail 5, which has a vertical control component 51 for controlling the vertical movement of the laser head 6. The cross slide formed by the x-axis slide rail 1 and the y-axis slide rail 2 can control the movement of the stage 3 on the plane, increasing the area of ​​laser engraving; at the same time, in conjunction with the z-axis slide rail 5, the laser head 6 can be set to slide up and down, enabling three-dimensional engraving of the workpiece.

[0047] Reference Figure 1 and Figure 2 The x-axis slide rail 1 is mainly composed of a metal housing 13 and a sliding control component 14 for controlling the sliding of the first sliding seat 11. The sliding control method between the x-axis slide rail 1 and the first sliding seat 11 can be implemented by various structures, such as synchronous belt drive, gear and rack drive or screw drive.

[0048] For example, when using a synchronous belt drive, the sliding control assembly 14 mainly includes a motor, a synchronous pulley, and a synchronous belt. The motor can control the synchronous pulley to rotate, and the synchronous pulley drives the synchronous belt to rotate. The synchronous belt passes through the lower end of the first sliding seat 11 and connects to the first sliding seat 11, thereby enabling the first sliding seat 11 to slide along the length direction of the x-axis slide rail 1. Furthermore, a guide rail can be provided inside the x-axis slide rail 1, and a slider is connected to the lower end of the first sliding seat 11. The slider slides on the guide rail, thereby improving the stability of the first sliding seat 11 when it moves. The internal structure of the y-axis slide rail 2 is the same as that of the x-axis slide rail 1, and will not be described again here. It should be noted that, in order to seal and protect the inside of the x-axis slide rail 1, a thin metal baffle is provided on the surface of the x-axis slide rail 1 by bolts. A clearance groove for the metal baffle is correspondingly provided on the first sliding seat 11. When the first sliding seat 11 slides, the first sliding seat 11 will not interfere with the metal baffle.

[0049] ReferenceFigure 3 and Figure 4 In this embodiment, the y-axis slide rail 2 is further rotatable relative to the x-axis slide rail 1, allowing it to rotate until it is parallel to the x-axis slide rail 1. This reduces the packaging volume and facilitates the storage of the x-axis slide rail 1 and the y-axis slide rail 2. Specifically, a first connecting shaft 111 is fixed to the upper surface of the first sliding seat 11. The first connecting shaft 111 extends vertically upward and is rotatably connected to the y-axis slide rail 2, allowing the y-axis slide rail 2 to rotate along the first connecting shaft 111. Simultaneously, a fixing member 21 is also provided on the y-axis slide rail 2. When the y-axis slide rail 2 rotates until it is perpendicular to the x-axis slide rail 1 in its horizontal projection, the fixing member 21 restricts the rotation of the y-axis slide rail 2.

[0050] Specifically, the fixing component 21 includes a fixing rod 212 and a handle 211 connected to each other. The fixing rod 212 can slide through the metal housing 13 of the y-axis slide rail 2. The handle 211 is located outside the metal housing 13 and serves to facilitate the control of the fixing rod 212. A seat is provided inside the y-axis slide rail 2 to be rotatably connected to the first connecting shaft 111. A fixing hole is provided on the side wall of the first connecting shaft 111. The end of the fixing rod 212 away from the handle 211 has an external thread, and the side wall of the fixing hole has an internal thread. When the y-axis slide rail 2 rotates to be perpendicular to the x-axis slide rail 1, the position of the fixing hole and the fixing rod 212 are in a straight line. By connecting the fixing rod 212 to the threaded fixing hole, the relative sliding between the first connecting shaft 111 and the y-axis slide rail 2 can be restricted, that is, the sliding of the y-axis slide rail 2 can be restricted.

[0051] Optionally, in order to achieve a detachable connection between the y-axis slide rail 2 and the first sliding seat 11, the first sliding seat 11 is divided into upper and lower parts, which are detachably connected by bolts. The lower first sliding seat 11 slides on the x-axis slide rail 1, and the upper first sliding seat 11 is connected to the first connecting shaft 111.

[0052] To improve the stability of the y-axis slide rail 2 and ensure its smooth rotation, two universal wheels 22 are connected to both ends of the y-axis slide rail 2. The two universal wheels 22 and the first sliding seat 11 jointly support the y-axis. In this embodiment, when the y-axis slide rail 2 slides to be parallel to the x-axis slide rail 1, the two universal wheels 22 slide to both ends of the x-axis slide rail 1 respectively.

[0053] Reference Figure 1 and Figure 5In this embodiment, the up-and-down control component 51 includes a first motor 511, a screw 512, and a guide rod 513. The first motor 511 is fixed inside the z-axis slide rail 5, and its output end is vertically upward. The screw 512 is rotatably mounted inside the z-axis slide rail 5 along the vertical direction, and its lower end is connected to the output end of the first motor 511. The guide rod 513 is fixed inside the z-axis slide rail 5 along the vertical direction. A third sliding seat 52 is slidably mounted on the side wall of the z-axis slide rail 5. The laser head 6 is fixed to the side wall of the third sliding seat 52 by bolts or other means. The screw 512 is threaded through the third sliding seat 52, and the guide rod 513 slides through the third sliding seat 52. When the third motor is started, it drives the screw 512 to rotate, which in turn drives the third sliding seat 52 to slide up and down, thereby driving the laser head 6 to slide up and down to perform three-dimensional engraving on the item placed on the platform 3.

[0054] The implementation principle of the multi-axis engraving system of this application embodiment is as follows: Before engraving, the y-axis slide rail 2 is rotated to a position perpendicular to the x-axis slide rail 1. Then, the rotation of the y-axis slide rail 2 is restricted by the fixing rod 212. Next, the workpiece to be processed is fixed on the table 3, and the equipment can be started to engrave the workpiece. During engraving, by sliding the first sliding seat 11 and the second sliding seat 23, the y-axis slide rail 2 and the table 3 are moved along the x-axis and y-axis directions, so as to perform horizontal two-dimensional engraving on the workpiece; by sliding the third sliding seat 52 up and down, the laser head 6 is moved up and down, so as to perform three-dimensional engraving on the workpiece.

[0055] Example 2:

[0056] Reference Figure 6 and Figure 7 The difference between this embodiment and Embodiment 1 is the addition of a flip adjustment component 7. This component 7 is positioned between the y-axis slide rail 2 and the worktable 3, and is used to drive the worktable 3 to flip along a horizontal axis. This allows the laser emitted by the laser head 6 to process the sidewall of the workpiece, or, when the workpiece is larger at the top and smaller at the bottom, to engrave the lower part of the workpiece. This increases the range of engraving scenarios, such as allowing for three-dimensional engraving of workpieces that are larger at the top and smaller at the bottom. In this embodiment, the rotation axis of the flip adjustment component 7 is parallel to the length direction of the y-axis slide rail 2, therefore the flip adjustment component 7 can drive the worktable 3 to flip along the length direction of the y-axis slide rail 2.

[0057] Reference Figure 6 and Figure 8Specifically, the flip adjustment assembly 7 includes a positioning seat 71, a rotating seat 72, and a second motor 73. The positioning seat 71 is detachably fixed to the second sliding seat 23 by bolts, and the rotating seat 72 is rotatably mounted on the positioning seat 71. The length directions of both the positioning seat 71 and the rotating seat 72 are parallel to the length direction of the y-axis slide rail 2. The second motor 73 is also fixed to the positioning seat 71 by bolts or other means. The axis of the output end of the second motor 73 is parallel to the length direction of the positioning seat 71. The output end of the second motor 73 is fixedly connected to one end of the rotating seat 72. When the second motor 73 is started, the rotating seat 72 can be rotated along the axis of the output end of the second motor 73, which can drive the shelf 3 to flip along the length direction of the y-axis slide rail 2.

[0058] Reference Figure 6 and Figure 8 The upper surface of the positioning seat 71 is provided with a rotating groove for the lower surface of the rotating seat 72 to abut and rotate. The lower surface of the rotating seat 72 is an arc-shaped surface, and the rotating groove is an arc-shaped groove. At the same time, in order to improve the stability of the rotating seat 72 when rotating, a guide strip can be provided along the circumferential direction on the lower surface of the rotating seat 72, and a guide groove can be provided on the positioning seat 71. The cross-section of the guide strip is set to T-shaped or dovetail-shaped, thereby ensuring the stability of the rotating seat 72 when rotating.

[0059] Reference Figure 6 and Figure 8 In this embodiment, a support assembly 8 can be further provided to support the shelf 3. Specifically, the support assembly 8 includes a first support rod 81, a second support rod 82, a positioning rod 83, and a first limiting member 84. The first support rod 81 and the second support rod 82 are preferably rectangular rods. The upper end of the second support rod 82 is rotatably connected to the shelf 3. Specifically, the lower surface of the shelf 3 can be pivoted via a support, with the pivot passing through the second support rod 82 and rotatably connected to it. The lower end of the second support rod 82 is slidably inserted into the first support rod 81, and the positioning rod 83 is fixedly installed on the lower side wall of the first support rod 81. A positioning groove 12 is provided on the side wall of the x-axis slide rail 1 facing the first support rod 81. The positioning groove 12 extends along the length of the x-axis slide rail 1, and the end of the positioning rod 83 away from the first support rod 81 is inserted into and slides within the positioning groove 12.

[0060] Reference Figure 6 and Figure 8The first limiting member 84 is used to restrict the second support rod 82 from sliding up and down within the first support rod 81. Specifically, the first limiting member 84 includes a first cylinder 841, a connecting rod 842, and a first limiting rod 843. The first cylinder 841 is fixed on the positioning seat 71, and the first limiting rod 843 is connected to the telescopic shaft of the first cylinder 841 through the connecting rod 842. The length direction of the telescopic shaft of the first cylinder 841 is parallel to the length direction of the y-axis slide rail 2, and the length direction of the first limiting rod 843 is also parallel to the length direction of the y-axis slide rail 2. A first limiting hole 811 is provided on the side wall of the first support rod 81 facing the first limiting rod 843, and a second limiting hole 821 is provided vertically on the side of the second support rod 82 facing the first limiting rod 843. Both the first limiting hole 811 and the second limiting hole 821 are set as oblong holes, and their extension directions are parallel to the length direction of the x-axis slide rail 1. When the first cylinder 841 is started, the connecting rod 842 drives the first limiting rod 843 to pass through the first limiting hole 811 and the second limiting hole 821 in sequence, thereby restricting the second support rod 82 from sliding up and down relative to the first support rod 81, thus supporting the upper shelf 3.

[0061] It should be noted that, since the second limiting holes 821 are spaced apart, in order to ensure that the first limiting rod 843 can always pass through the second limiting hole 821, the second motor 73 is preferably a stepper motor, and can rotate a fixed angle each time, so that the first limiting hole 811 can always be aligned with a certain second limiting hole 821.

[0062] Optionally, to further improve the support effect on the shelf 3, multiple sets of the first support rod 81 and the second support rod 82 can be arranged along the circumference of the shelf 3. In this embodiment, four sets of the first support rod 81 and the second support rod 82 are arranged, and four first limiting rods 843 are also arranged. Through the connection of the connecting rod 842, the four first limiting rods 843 are arranged one-to-one with the first limiting holes 811 of the first support rod 81, so that the first cylinder 841 can simultaneously control the four first limiting rods 843 to be inserted into the first limiting holes 811 on the four first support rods 81 respectively.

[0063] In other embodiments, an abutment method can be used instead of the cooperation between the first limiting rod 843 and the second limiting hole 821. That is, the side wall of the second support rod 82 facing the first limiting rod 843 is provided with an anti-slip frosted surface, and the corresponding end face of the first limiting rod 843 is also provided with an anti-slip surface. By controlling the first limiting rod 843 to pass through the first limiting hole 811 and make the end face of the first limiting rod 843 abut against the side wall of the second support rod 82, the second support rod 82 is limited. At this time, the friction between the first limiting rod 843 and the second support rod 82 supports the upper platform 3. This method can further increase the control accuracy of the rotation angle of the platform 3.

[0064] The implementation principle of the multi-axis engraving system of this application embodiment is as follows: Before use, the flip adjustment component 7 is first installed on the multi-axis engraving system. Then, when it is necessary to engrave the side wall of the workpiece, the second motor 73 is started to drive the stage 3 to flip at a certain angle. When the stage 3 flips, it drives the second support rod 82 to move up and down. At the same time, the stage 3 will also drive the first support rod 81 and the second support rod 82 to move a certain distance along the length direction of the x-axis slide rail 1. After the stage 3 is flipped, the first cylinder 841 is started. The first cylinder 841 drives the first limit rod 843 to pass through the first limit hole 811 and the second limit hole 821 in sequence, which can restrict the up and down movement of the second support rod 82, that is, realize the locking of the position of the second support rod 82, thereby ensuring the stability of the stage 3 during the processing.

[0065] Example 3:

[0066] Reference Figure 9 and Figure 10 The difference between this embodiment and Embodiment 2 is that a rotation adjustment component is added, and the platform 3 is set as a rotatable structure. The rotation adjustment component is used to drive the workpiece on the platform 3 to continue to rotate on the basis of flipping and tilting, so as to facilitate circumferential carving of the workpiece.

[0067] Reference Figure 9 and Figure 10 In this embodiment, the platform 3 includes an outer mounting frame 31 and a rotating inner plate 32. The outer mounting frame 31 is fixed to the rotating seat 72 by bolts or other means, and the rotating inner plate 32 is rotatably disposed inside the outer mounting frame 31. Correspondingly, the upper surface of the rotating inner plate 32 can be provided with a slot to cooperate with the snap-fit ​​fixing structure to fix the workpiece to be processed. At the same time, in order to reduce the volume, both the rotating inner plate 32 and the outer mounting frame 31 can be set as circular structures.

[0068] The rotation adjustment assembly includes a power component 91 and a second limiting component 92. The power component 91 can be a third motor, which can be fixed to the mounting frame 31 or the rotating seat 72. In this embodiment, to improve the compactness of the equipment, the third motor is embedded in the rotating seat 72. The output shaft of the third motor rotates through the rotating seat 72 and the mounting frame 31 and is fixedly connected to the rotating inner plate 32. Thus, when the second motor 73 rotates the stage 3 to carve the side wall of the workpiece, the third motor can be turned on simultaneously to drive the rotating inner plate 32 and the workpiece set on the rotating inner plate 32 to rotate, thereby carving the side wall of the workpiece in the circumferential direction.

[0069] Reference Figure 9 and Figure 10In an optional embodiment, the second limiting member 92 includes a second cylinder and a second limiting rod. The second cylinder is preferably fixed on the rotating seat. To facilitate the installation of the second cylinder, a rectangular plate can be fixed on the side wall of the rotating seat, and the second cylinder is installed through the rectangular plate. The telescopic shaft of the second cylinder extends toward the platform 3, and the second limiting rod is connected to the telescopic shaft of the second cylinder. The length direction of the second limiting rod is parallel to the axial direction of the output shaft of the third motor. A third limiting hole 311 is provided on the side wall of the mounting frame 31 for the second limiting rod to pass through, and a fourth limiting groove 321 is provided on the side wall of the rotating inner plate 32 facing the rotating seat 72 for the second limiting rod to be inserted. The second cylinder can drive the second limiting rod to pass through the third limiting hole 311 and be inserted into the fourth limiting groove 321, thereby fixing the rotating inner plate 32.

[0070] When the workpiece angle needs to be adjusted, the second cylinder drives the second limiting rod to retract from the fourth limiting groove 321, thereby releasing the restriction on the rotating inner plate 32 and allowing it to rotate freely under the drive of the third motor. Once the target angle is reached, the second cylinder actuates again, pushing the second limiting rod through the third limiting hole 311 and into the corresponding fourth limiting groove 321, reliably fixing the rotating inner plate 32 and ensuring stability and precision during the engraving process. This design not only improves the flexibility of workpiece processing but also effectively avoids processing errors caused by accidental movement of the rotating inner plate 32.

[0071] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
