Description
Technical Field
[0001] This utility model relates to the technical field of engraving machines, and specifically to a multi-station billiard cue engraving machine. Background Technology
[0002] Engraving machines are widely used in woodworking, advertising, crafts, mold making, construction, printing and packaging, and decoration industries. They can engrave various materials such as plywood, MDF, acrylic, PVC, marble, jade, and glass, meeting the engraving needs of different industries.
[0003] In existing multi-head engraving machines, multiple engraving mechanisms are generally moved horizontally through the same horizontal moving mechanism. Although multiple engraving mechanisms can perform multi-station processing simultaneously, if a processing problem or malfunction occurs at one station, or if a tool change is required, the entire machine must be stopped to troubleshoot or change the tool, which seriously affects the processing efficiency of the engraving operation. At the same time, because the engraving mechanisms of this type of machine can only move synchronously, it is not possible to engrave different types of billiard cues at the same time at each station. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a multi-station billiard cue engraving machine. This engraving machine enables each engraving unit to operate independently, allowing all engraving units to process the same product simultaneously, greatly improving processing efficiency. It also enables each engraving unit to independently process more than two products, significantly enhancing the flexibility of engraving style settings, ensuring the normal progress of product engraving operations, guaranteeing the normal processing schedule, realizing integrated round and flat engraving operations, ensuring accurate displacement adjustment, and achieving automatic switching from roughing to finishing.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A multi-station billiard cue engraving machine includes a worktable with a main control unit on one side. At least one engraving unit is mounted on the worktable, and the engraving unit is electrically connected to the main control unit via a secondary electrical control unit.

The engraving unit includes an engraving mechanism mounted on one side of the mounting frame via a displacement adjustment mechanism and a cue adjustment mechanism located below the engraving mechanism. The cue adjustment mechanism adjusts the processing position of the workpiece, and the engraving mechanism works in conjunction with the cue adjustment mechanism to process the workpiece. The displacement adjustment mechanism horizontally adjusts the engraving feed position of the engraving mechanism.
[0007] The mounting frame consists of a support base on each side of the workbench, a support plate between the two support bases, at least one first guide rail on one side of the support plate, and at least one heat dissipation component on the other side of the support plate. The support base is used to fix the support plate, the first guide rail is used to assist the displacement adjustment mechanism in moving the engraving mechanism horizontally, and the heat dissipation component is used to dissipate heat from the displacement adjustment mechanism.
[0008] The engraving mechanism includes a lead screw module that is connected to a displacement adjustment mechanism via a nut, a tool drive unit that is mounted on the sliding side of the lead screw module via a mounting base, and a tool that is mounted on the output end of the tool drive unit via a pneumatic connecting base. The lead screw module is used to drive the tool holder to move the tool drive unit up and down. The tool drive unit is used to provide driving force for the rotation of the tool. The tool is used to process the workpiece to be processed. The lead screw module is also slidably connected to a first guide rail via at least one first slider.
[0009] A sensing plate is provided at one end of the lead screw module, and a sensor is provided on the support plate of the mounting frame. The sensor is electrically connected to the auxiliary electric control unit and is used to locate the horizontal position of the engraving mechanism in conjunction with the sensing plate.
[0010] The cue adjustment mechanism includes a linear motion module on the worktable, a back plate on the sliding surface of the linear motion module, a main rotating component at one end of the linear motion module, and an auxiliary rotating component at the other end of the linear motion module. The linear motion module is used to drive the rotating component to move back and forth. The main rotating component is used to drive the workpiece to be processed to rotate in conjunction with the engraving mechanism for processing. The auxiliary rotating component is used to adjust the clamping position of the workpiece to be processed and to assist the main rotating component in rotating the workpiece to be processed.
[0011] The main rotating assembly includes a rotary motor mounted on one end of the back plate via a motor mount and a first chuck mounted on the output end of the rotary motor via a motor shaft sleeve. The motor shaft sleeve passes through the motor mount. The first chuck is used to limit the workpiece to be processed, and the rotary motor is used to drive the first chuck to rotate the workpiece to be processed.
[0012] The auxiliary rotating assembly includes at least one second guide rail disposed on the back plate, at least one second slider disposed above the second guide rail, and a second chuck disposed at the other end of the back plate via a rotating seat. The second slider is fixedly connected to the rotating seat, and the second chuck is used to assist the main rotating assembly in limiting the workpiece to be processed. The rotating seat is used to cooperate with the first chuck to rotate the second chuck synchronously.
[0013] The linear motion module has a tool magazine on one side for storing tools of different specifications. A tool setter is located at one end of the tool magazine and is electrically connected to the auxiliary electronic control unit. The tool setter is used to calibrate the engraving mechanism when changing tools.
[0014] The cue adjustment mechanism is equipped with a dust collection component on one side, which is used to simultaneously clean up the excess material generated by the engraving mechanism during the processing of the workpiece.
[0015] The displacement adjustment mechanism includes a stepper motor located on one side of the support base and a threaded screw with one end connected to the output end of the stepper motor via a coupling. The other end of the threaded screw is fixed to one side of the support plate via a bearing.
[0016] The beneficial effects of this utility model are as follows:
[0017] 1. Two or more engraving units are set up on the workbench. Each engraving unit is connected to the main control unit through an independently configured auxiliary control unit. The main control unit acts as the control center, and the engraving program is distributed to each auxiliary control unit according to the actual engraving needs. The auxiliary control unit then independently controls the connected engraving units to achieve independent operation of each engraving unit. This allows the engraving units to process the same product simultaneously, greatly improving the product processing efficiency. It also allows each engraving unit to independently process more than two products, greatly improving the flexibility of engraving style settings. Moreover, when processing problems are encountered or one of the engraving units malfunctions, only the engraving unit with the processing problem or malfunction needs to be paused, while the other engraving units can still work normally, thus ensuring the normal progress of product engraving operations and guaranteeing the normal processing schedule of the product.
[0018] 2. Each engraving mechanism is independently driven by a displacement adjustment mechanism to achieve horizontal reciprocating displacement in the Y direction. This, in conjunction with the lead screw module of the engraving mechanism, enables the vertical feed of the tool drive component, thereby controlling the engraving displacement and feed amount of the tool on the tool drive component. Simultaneously, the main and auxiliary rotating components of the cue adjustment mechanism clamp and support the workpiece to be processed, achieving circumferential rotation of the workpiece during engraving operations. The linear motion module drives the main and auxiliary rotating components to achieve horizontal reciprocating displacement in the X direction. Through the cooperation of the displacement adjustment mechanism, the engraving mechanism, and the cue adjustment mechanism, the round engraving operation on the surface of the billiard cue can be realized, shaping the billiard cue into a round form. After the round engraving operation is completed, patterns can be engraved on the surface of the billiard cue according to the decorative needs, thus achieving integrated round and flat engraving operations.
[0019] 3. A heat dissipation component is installed on the mounting bracket to continuously dissipate heat from the displacement adjustment mechanism through air cooling or liquid cooling, avoiding changes in component performance due to heat generated by thread meshing friction, and ensuring the accuracy of displacement adjustment; the sensor and the sensing plate work together to position the horizontal position of the engraving mechanism; the lead screw module is slidably connected to the first guide rail through the first slider, driving the tool drive component to move up and down to achieve vertical fine adjustment, so that the tool and the workpiece to be processed maintain the set processing distance; the linear motion module in the displacement adjustment mechanism drives the back plate to move back and forth to adjust the axial position of the workpiece to be processed; the main rotation component and the auxiliary rotation component work together to realize the rotation of the workpiece to be processed and the clamping position adjustment, ensuring that the engraving mechanism processes along the preset trajectory.
[0020] 4. The pneumatic connector for the tool drive unit facilitates tool connection and enables automatic tool changing through start-up control of the pneumatic connector. Combined with the tool magazine on the linear motion module, it stores tools of different specifications, providing options for tool replacement via the pneumatic connector. This invention allows for automatic switching of the engraving unit from roughing to finishing through tool replacement. The tool sensor on one side of the tool magazine calibrates the pneumatic connector during tool replacement, ensuring the engraving mechanism accurately resets to the starting point of the machining trajectory after a new tool is installed.

Detailed Implementation
[0030] The present invention will be further described below with reference to the accompanying drawings:
[0031] like Figure 1-7 As shown, this utility model relates to a multi-station billiard cue engraving machine, including a worktable 1. A main control unit 2 is located on one side of the worktable 1. At least one engraving unit 5 is mounted on the worktable 1. The engraving unit 5 is electrically connected to the main control unit 2 via a secondary electrical control unit 3. The secondary electrical control unit 3 is used to receive control commands from the main control unit 2 and to regulate the connected engraving unit 5. A mounting frame 4 is provided on the worktable 1. The engraving unit 5 includes an engraving mechanism 52 mounted on one side of the mounting frame 4 via a displacement adjustment mechanism 50, and an engraving mechanism 52 mounted on the engraving unit 5. The ball-stick adjustment mechanism 54 below the engraving mechanism 52 is used to adjust the processing position of the workpiece to be processed. The engraving mechanism 52 is used to cooperate with the ball-stick adjustment mechanism 54 to process the workpiece to be processed. The displacement adjustment mechanism 50 is used to horizontally adjust the engraving feed position of the engraving mechanism 52. The main control unit 2 is fixedly connected to the worktable 1 through a support frame 20. Two or more engraving units 5 can be set on the worktable, which can be configured according to actual production needs. This application does not limit the configuration.
[0032] like Figure 1 , 3 As shown in Figure 4, the mounting frame 4 consists of a support base 40 on each side of the worktable 1, a support plate 41 between the two support bases 40, at least one first guide rail 42 on one side of the support plate 41, and at least one heat dissipation assembly 43 on the other side of the support plate 41. The support base 40 is used to fix the support plate 41. The first guide rail 42 is used to assist the displacement adjustment mechanism 50 in horizontally moving the engraving mechanism 52. The heat dissipation assembly 43 is used to dissipate heat from the displacement adjustment mechanism 50. When the displacement adjustment mechanism 50 drives the engraving mechanism 52 to horizontally adjust the engraving feed position, its threaded screw 502 engages with the nut 51. During continuous operation, they rub against each other and generate a large amount of heat, which is cooled by the heat dissipation assembly 43 to maintain the working performance of each component of the displacement adjustment mechanism 50. The displacement adjustment mechanism 50 can remain unchanged, thus ensuring the accuracy of the displacement adjustment of the engraving mechanism 52 by the displacement adjustment mechanism 50. Preferably, the support plates 41 are firmly supported by the support seats 40 symmetrically arranged on both sides of the worktable 1 to form a rigid mounting base. Two sets of first guide rails 42 arranged longitudinally on one side of the support plate 41 provide horizontal movement guidance for the displacement adjustment mechanism 50. Two sets of heat dissipation components 43 on the other side continuously manage the heat of the displacement adjustment mechanism 50 through air cooling or liquid cooling. During continuous processing, the heat dissipation components 43 continuously remove the heat generated by the operation of the displacement adjustment mechanism 50. A signal indicator light 1e is provided above the support plate 41. The signal indicator light 1e is electrically connected to the auxiliary electric control unit 3. The signal indicator light 1e is used to receive the instructions of the auxiliary electric control unit 3 and issue indicator signals representing different working conditions.
[0033] like Figure 2 , 5As shown, further, one side of the worktable 1 is respectively provided with a first modulator 61 electrically connected to the first auxiliary electrical control unit 1a, a second modulator 71 electrically connected to the second auxiliary electrical control unit 1b, a third modulator 81 electrically connected to the third auxiliary electrical control unit 1c, and a fourth modulator 91 electrically connected to the fourth auxiliary electrical control unit 1d. The first modulator 61 includes an axial adjustment knob, a speed adjustment knob, an emergency stop button, and a hand-cranked pulse generator. The first modulator 61 adjusts the initial working position of the first engraving mechanism 52. During the first processing, it transmits control commands to the first auxiliary electrical control unit 1a through the axial adjustment knob to control the displacement fine adjustment direction of the first engraving mechanism 52 in the X, Y, and Z axes, and adjusts the first... The fine-tuning displacement of the engraving mechanism 52 along the X, Y, and Z axes is controlled by the rate adjustment knob, which controls the feed rate of the ball bar adjustment mechanism 54. After the initial position of the first engraving mechanism 52 is adjusted, the initial processing positions of the second, third, and fourth engraving mechanisms 52 are adjusted sequentially. During the manual adjustment process of the first modulator 61, the data is synchronized to the main control unit 2 in real time by the first auxiliary electrical control unit 1a. After the initial position of the first engraving mechanism 52 is adjusted to the correct position, the main control unit 2 promptly sends a command to the first auxiliary electrical control unit 1a. The first auxiliary electrical control unit 1a controls the indicator light 1e to emit an indicator signal to ensure the accuracy of the initial position. In subsequent continuous processing, manual adjustment is no longer required, and each processing step is controlled by the main control unit 2.
[0034] like Figure 5-6 As shown, the engraving mechanism 52 includes a lead screw module 520 connected to a displacement adjustment mechanism 50 via a nut 51, a tool drive 522 mounted on the sliding side of the lead screw module 520 via a mounting base 521, and a tool 524 mounted on the output end of the tool drive 522 via a pneumatic connecting base 523. The lead screw module 520 drives the tool holder to move the tool drive 522 up and down, the tool drive 522 provides driving force for the rotation of the tool 524, and the tool 524 is used to process the workpiece. The lead screw module 520 is also slidably connected to the first guide rail 42 via at least one first slider 53; the engraving mechanism 52 is the core execution terminal, which directly acts on the workpiece to be processed. The engraving mechanism 52 achieves precise engraving action of the tool 524 in three-dimensional space through the vertical movement of the lead screw module 520 in conjunction with the displacement adjustment mechanism 50. The engraving mechanism 52 drives the mounting base 521 through the lead screw module 520 to drive the tool drive component 522 to perform vertical fine adjustment, so that the rotating tool 524 maintains the set processing distance with the ball rod surface.
[0035] like Figure 5-6As shown, a sensor plate 55 is provided at one end of the lead screw module 520, and a sensor 56 is provided on the support plate 41 of the mounting bracket 4. The sensor 56 is electrically connected to the auxiliary electric control unit 3. The sensor 56 is used to cooperate with the sensor plate 55 to position the horizontal position of the engraving mechanism 52.
[0036] like Figure 5 , 7As shown, the cue stick adjustment mechanism 54 includes a linear motion module 540 mounted on the worktable 1, a back plate 541 mounted on the sliding surface of the linear motion module 540, a main rotating assembly 542 mounted at one end of the linear motion module 540, and an auxiliary rotating assembly 543 mounted at the other end of the linear motion module 540. The linear motion module 540 drives the rotating assembly to move back and forth. The main rotating assembly 542 drives the workpiece to be processed to rotate in conjunction with the engraving mechanism 52 for processing. The auxiliary rotating assembly 543 adjusts the clamping position of the workpiece to be processed and assists the main rotating assembly 542 in rotating the workpiece to be processed. The cue stick adjustment mechanism 54 is the core mechanism for achieving precise positioning and dynamic processing of the workpiece to be processed. When it is working: when the workpiece to be processed... After the workpiece is clamped bidirectionally by the first chuck 5423 and the second chuck 5433, the rotary motor 5421 of the main rotary assembly 542 drives the first chuck 5423 to rotate, synchronously driving the second chuck 5433 of the auxiliary rotary assembly 543 to rotate in conjunction, forming a rigid clamping and synchronous rotation of the workpiece to be processed. At this time, the linear motion module 540 drives the back plate 541 to translate back and forth according to the instructions of the auxiliary electric control unit 3, so that the axial position of the workpiece to be processed is precisely matched with the feed path of the tool 524 of the engraving mechanism 52. During the processing, the main rotary assembly 542 outputs rotational power according to the instructions of the auxiliary electric control unit 3, and the auxiliary rotary assembly 543 adjusts the sliding of the second slider 5431 on the second guide rail 5430. To compensate for the slight axial displacement of the workpiece caused by rotation, the engraving mechanism 52 always runs along the preset spiral processing trajectory on the surface of the workpiece. When it is necessary to change the processing position or adjust the processing parameters, the linear motion module 540 can quickly respond to the instructions from the auxiliary electronic control unit 3 and the main control unit 2. By changing the displacement of the back plate 541, the relative position relationship between the workpiece and the engraving mechanism 52 is changed. In conjunction with the speed adjustment of the main rotating component 542, the adjustment of different processing points is achieved. When the engraving mechanism 522 is changing the tool 524, the ball bar adjustment mechanism 54 pauses the rotational motion and moves to the initial position. After the tool setter 58 is calibrated with the engraving mechanism 52, the tool 524 is changed through the pneumatic connecting seat 523. The 0-drive workpiece is fed slightly along the axial direction, so that the contact point between the new tool 524 and the surface of the workpiece is accurately reset to the starting point of the machining trajectory. Throughout the machining cycle, the dust collection component 59 removes the debris and dust generated on the surface of the workpiece in real time through the negative pressure adsorption system, avoiding the impact of machining residue on the dynamic balance of the rotating component and the transmission accuracy of the displacement adjustment mechanism 50. After the workpiece completes single-station machining, the linear motion module 540 drives the back plate 541 to quickly return to the initial clamping position, the main rotating component 542 stops operating, and the first chuck 5423 and the second chuck 5433 release the workpiece. The workpiece is unloaded and the new workpiece is clamped by a robot or manually. Closed-loop control is achieved through real-time data interaction between the auxiliary electronic control unit 3 and the main control unit 2.
[0037] like Figure 7 As shown, the main rotating assembly 542 includes a rotary motor 5421 mounted on one end of the back plate 541 via a motor mount 5420, and a first chuck 5423 mounted on the output end of the rotary motor 5421 via a motor bushing 5422. The motor bushing 5422 passes through the motor mount 5420. The first chuck 5423 is used to limit the workpiece to be processed, and the rotary motor 5421 is used to drive the first chuck 5423 to rotate the workpiece to be processed. The rotary motor 5421 receives pulse signals from the main control unit 2 or the auxiliary control unit 3, and accurately transmits torque through the motor bushing 5422. The first chuck 5423 is used to radially clamp the workpiece and limit its movement. During the processing, the rotary motor 5421 outputs a controllable speed to drive the first chuck 5423 to rotate the workpiece around its own axis, so that the cutting tool 524 of the engraving mechanism 52 can form a continuous spiral process along the surface of the workpiece. When it is necessary to adjust the processing parameters, the operator can send a command to the auxiliary electrical control unit 3 through the main control unit 2 to correct the speed and start / stop status of the rotary motor 5421 in real time, so as to ensure that the rotation angle of the workpiece and the feed speed of the engraving mechanism 52 are precisely matched.
[0038] like Figure 7 As shown, the auxiliary rotating assembly 543 includes at least one second guide rail 5430 disposed on the back plate 541, at least one second slider 5431 disposed above the second guide rail 5430, and a second chuck 5433 disposed at the other end of the back plate 541 via a rotating seat 5432. The second slider 5431 is fixedly connected to the bottom of the rotating seat 5432. The second chuck 5433 is used to assist the main rotating assembly 542 in limiting the workpiece to be processed. The rotating seat 5432 is used to cooperate with the first chuck 5423 to rotate the second chuck 5433 synchronously.
[0039] like Figure 5 , 7 As shown, a tool magazine 57 is provided on one side of the linear motion module 540. The tool magazine 57 is used to store tools 524 of different specifications. A tool setter 58 is provided at one end of the tool magazine 57. The tool setter 58 is electrically connected to the auxiliary electronic control unit 3. The tool setter 58 is used to perform calibration when the engraving mechanism 52 changes tools 524.
[0040] like Figure 5 As shown, a dust collection component 59 is provided on one side of the cue adjustment mechanism 54. The dust collection component 59 is used to simultaneously clean the excess material generated by the engraving mechanism 52 during the processing of the workpiece.
[0041] like Figure 1 , 3As shown, the displacement adjustment mechanism 50 includes a stepper motor 500 disposed on one side of the support base 40, and a threaded screw 502 disposed at the output end of the stepper motor 500 via a coupling 501. One end of the threaded screw 502 is rotatably connected to a bearing 503 and a shaft seat 504. The shaft seat 504 is fixedly connected to one side of the support plate 41. The threaded screw 502 is threadedly connected to a nut 51. The stepper motor 500 serves as a power source. When it receives an electrical pulse signal, its output shaft rotates at a set step angle. The output end of the stepper motor 500 transmits the rotational motion to the threaded screw 502 via the coupling 501. One end of the screw 502 is connected to the bearing 503 and the bearing 504 fixed to the support plate 41 to ensure stable rotation of the screw 502. The screw 502 is threadedly engaged with the nut 51. When the screw 502 rotates, the nut 51 moves linearly along the axial direction of the screw 502 according to the pitch. The bearing 503 supports the screw 502 and reduces the friction with the bearing 504 to ensure smooth and precise movement. The rotational motion of the stepper motor 500 is converted into the linear displacement of the nut 51, thereby driving the engraving mechanism 52 to move along the first guide rail 42 through the first slider 53, realizing the horizontal adjustment of the engraving feed position of the engraving mechanism 52.
[0042] The following is an explanation of a preferred configuration of four engraving units 5:
[0043] like Figure 2As shown, preferably, the worktable 1 is equipped with a first engraving unit 6 electrically connected to a first auxiliary electronic control unit 1a, a second engraving unit 7 electrically connected to a second auxiliary electronic control unit 1b, a third engraving unit 8 electrically connected to a third auxiliary electronic control unit 1c, and a fourth engraving unit 9 electrically connected to a fourth auxiliary electronic control unit 1d, all mounted on a mounting bracket 4. The first auxiliary electronic control unit 1a, second auxiliary electronic control unit 1b, third auxiliary electronic control unit 1c, and fourth auxiliary electronic control unit 1d are mounted below the worktable 1. Each of these units is independently electrically connected to the main control unit 2. The first displacement adjustment mechanism 60 of the first engraving unit 6, the second displacement adjustment mechanism 70 of the second engraving unit 7, the third displacement adjustment mechanism 80 of the third engraving unit 8, and the fourth engraving unit 9 are also included. The fourth displacement adjustment mechanism 90 of the engraving unit 9 is installed in pairs on both sides of the mounting frame 4. The main control unit 2 issues control commands to the first auxiliary electric control unit 1a, the second auxiliary electric control unit 1b, the third auxiliary electric control unit 1c, and the fourth auxiliary electric control unit 1d respectively. When the first auxiliary electric control unit 1a receives the command, it controls the first engraving unit 6 to perform processing operations. Through the independent operation of the first engraving unit 6, the second engraving unit 7, the third engraving unit 8, and the fourth engraving unit 9, when one engraving unit completes a process or needs to stop to change tools, it will not affect the operation of other engraving units. This realizes multi-station uninterrupted processing production, which greatly improves production efficiency. Furthermore, the control commands of the main control unit 2 can enable each engraving unit to complete different processing processes, improving the adaptability of diversified production products.
[0044] It should be noted that, in order to facilitate further description of the spatial arrangement of the four engraving units 5 in the preferred embodiment, the first auxiliary electronic control unit 1a, the second auxiliary electronic control unit 1b, the third auxiliary electronic control unit 1c, and the fourth auxiliary electronic control unit 1d, as well as the first engraving unit 6, the second engraving unit 7, the third engraving unit 8, and the fourth engraving unit 9 in the above preferred embodiment are structurally no different from the auxiliary electronic control unit 3 and the engraving unit 5. Therefore, the features not explained in the preferred embodiment are explained using the features in the engraving unit 5.
[0045] Working principle: In the processing preparation stage, the operator radially clamps the workpiece to be processed through the first chuck 5423 of the main rotating assembly 542 and the second chuck 5433 of the auxiliary rotating assembly 543, forming a rigid clamping limit. Then, the initial parameters are set through the modulators corresponding to each engraving unit 5. The initial position of the engraving mechanism 52 in the X, Y, and Z axes is finely adjusted using the axial adjustment knob and the hand-cranked pulse generator. At the same time, the feed rate of the linear motion module 540 is preset through the rate adjustment knob. The main control unit 2 receives the synchronous adjustment data from the auxiliary electrical control unit 3 in real time. When the initial position calibration of the first engraving unit 5 is completed, the main control unit 2 triggers the signal indicator light 1e to issue a ready signal. After the processing preparation process is completed and the processing execution stage begins, the main control unit 2 sends processing instructions to each auxiliary electrical control unit 3. The first to fourth engraving units (6, 7, 8, 9) start independently according to the preset program. The stepper motor 500 of the displacement adjustment mechanism 50 receives the electrical pulse signal and drives the threaded screw 502 to rotate. Through the cooperation of the nut 51 and the first guide rail 42, the engraving mechanism 52 is driven to perform horizontal feed along the longitudinal direction of the support plate 41. The screw module 520 of the engraving mechanism 52 synchronously drives the tool drive component 522 to perform vertical fine adjustment, so that the high-speed rotating tool 524 maintains a constant processing distance with the surface of the workpiece. At this time, the main rotation component 542 of the ball bar adjustment mechanism 54 rotates the motor 5421. Driven by the first chuck 5423, the engraving mechanism 52 rotates, ensuring continuous processing along a preset trajectory. Simultaneously, the dust collection component 59 activates the negative pressure adsorption system to remove processing residue. When switching processing steps or changing the tool 524 is required, the tool switching process begins. The linear motion module 540 drives the back plate 541 to perform axial displacement according to the instructions of the main control unit 2, adjusting the relative position between the workpiece and the engraving mechanism 52. The engraving mechanism 52 pauses operation and moves to its initial position. The tool setter 58 initiates the calibration program. After the tool 524 in the tool magazine 57 is replaced via the pneumatic connecting seat 523, the linear motion module 540 drives the back plate 541 to... Axial feed ensures that the new tool 524 is precisely reset to the starting point of the machining trajectory. During the machining completion stage, after a single engraving unit 5 completes the preset process, the linear motion module 540 drives the back plate 541 to return to the initial clamping position, the main rotary component 542 stops operating and releases the first chuck 5423, and the finished product is unloaded and the new workpiece is clamped by an automated robot or manually. Throughout the entire machining cycle, the heat dissipation component 43 continuously manages the heat of the displacement adjustment mechanism 50, and the sensor 56 and the sensing plate 55 monitor the horizontal position of the engraving mechanism 52 in real time. All machining data are dynamically synchronized through the closed-loop control system of the auxiliary electrical control unit 3 and the main control unit 2 to ensure the continuity of multi-station collaborative operation and machining accuracy.
