Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and in particular to a compact laser cutting device. Background Art

[0002] With the booming manufacturing industries of hardware accessories, automotive parts, and other sectors, and the continued expansion of the market, demand for mass cutting is rapidly increasing. To meet the demands of efficient production, laser cutting equipment, with its advantages of high precision and high speed, has found widespread application in these fields, leading to a surge in overseas export sales. In international trade, to reduce transportation costs and improve efficiency, laser cutting equipment must be able to be directly loaded into containers, posing a significant challenge to its compact design.

[0003] Laser cutting equipment typically relies on the coordinated operation of the X-axis, Y-axis, Z-axis, B-axis, C-axis, and U-axis, giving the laser cutting head flexible multi-axis motion capabilities. This allows it to handle complex and diverse cutting processes, achieving high-precision cutting tasks such as special-shaped contours and multi-dimensional bevels. However, existing technologies have numerous issues with the multi-axis linkage design of laser cutting heads, severely restricting further improvements in equipment performance.

[0004] Taking the multi-axis linkage scheme of the laser head disclosed in the patent (publication number CN 221134474U) as an example, it has obvious defects in its structural design. In this scheme, a flat bottom plate is fixed at the bottom of the Z-axis drive assembly, and the C-axis rotary drive assembly is directly installed on the flat bottom plate. Due to the constraints of the company's manufacturing and processing accuracy, it is difficult to ensure absolute flatness during the processing of the flat bottom plate, and the C-axis rotary drive assembly will inevitably produce certain errors during installation, which leads to the C-axis being prone to motion deflection in actual operation. Moreover, once the installation is completed, due to structural limitations, the verticality of the C-axis cannot be effectively adjusted, which seriously affects the accuracy and quality of laser cutting, and limits the application of this type of laser cutting equipment in the batch cutting production of hardware accessories, automotive parts, etc. that require high cutting accuracy.

[0005] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the Invention

DETAILED DESCRIPTION

[0034] The present invention provides a compact laser cutting device. To make the objectives, technical solutions, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only intended to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0035] See also Figures 1 to 7The present invention provides a compact laser cutting device, comprising a frame 1, a beam slide 2 slidably arranged on the top of the frame 1, a Y-axis driving mechanism 3 for driving the beam slide 2 to move forward and backward, a T-shaped slide 41 slidably arranged on the beam slide 2, an X-axis driving mechanism 42 for driving the T-shaped slide 41 to move left and right, a Z-axis square tube 51 slidably arranged on the T-shaped slide 41, a Z-axis driving mechanism 50 for driving the Z-axis square tube 51 to move up and down, a flat bottom plate 52 fixed to the bottom of the Z-axis square tube 51, a bent frame 53 arranged below the flat bottom plate 52, and a plate arranged at the upper end of the bent frame 53. The C-axis motor 54, the B-axis motor 55 arranged at the lower end of the bending frame 53, the U-axis linear module 58 connected to the output end of the B-axis motor 55 and the laser cutting head 59 arranged on the slide of the U-axis linear module 58, the head of the C-axis motor 54 is mounted on a hanging plate 56, the middle part of the hanging plate 56 is provided with an avoidance opening 563 for the body of the C-axis motor 54 to pass through, and the hanging plate 56 is connected to the flat bottom plate 52 through a leveling structure; a cutting station is provided in the frame 1 and the workpiece is transported from the outside of the frame 1 to the cutting station for cutting processing through a self-positioning sliding workbench 6.

[0036] When the laser cutting structure is debugged and installed on site, the leveling structure can be used to adjust the horizontality of the suspension plate 56 relative to the flat base plate 52, thereby indirectly adjusting the posture of the C-axis motor 54, so that the cutting module associated with the C-axis motor 54 can operate in a suitable horizontal state, ensuring the movement coordination and accuracy between the various components during the laser cutting process, and reducing cutting errors or unstable equipment operation caused by poor postures such as tilt.

[0037] Compared to existing technologies, the compact laser cutting equipment provided by the present invention can precisely adjust the axis position of the C-axis motor 54 through a leveling structure, which helps improve the quality of cut products, reduce scrap rates, and effectively enhance the overall precision of the laser cutting equipment, ensuring the accuracy of the cutting module's motion during operation. Furthermore, the leveling structure helps maintain stable operation of the equipment, reducing vibration and wear caused by poor component position, thereby extending the equipment's service life, reducing maintenance costs and downtime, and improving production efficiency. This can better meet production needs and ensure product quality in mass cutting production in manufacturing sectors such as hardware accessories and automotive parts.

[0038] This compact laser cutting equipment is built on a stable frame 1, which serves as the supporting skeleton of the entire equipment, carrying various components and providing a stable environment for the cutting operation. The Y-axis drive mechanism 3 is installed on the top of the frame 1, which is connected to the slidable crossbeam slide 2. By driving the crossbeam slide 2 to move smoothly back and forth, the laser cutting head 59 is able to move over a large range in the longitudinal direction of the equipment, quickly positioning it at different longitudinal positions of the workpiece, and laying the foundation for subsequent cutting actions. The T-shaped slide 41 provided on the crossbeam slide 2 can slide left and right under the action of the X-axis drive mechanism, and cooperate with the Y-axis movement, so that the laser cutting head 59 can accurately reach any coordinate point in the plane of the workpiece to meet the needs of plane cutting. The Z-axis drive mechanism 50 drives the Z-axis square tube 51 to rise and fall vertically on the T-shaped slide 41, driving the components connected below and the laser cutting head 59 to adjust their height to adapt to the cutting of workpieces of different thicknesses. The C-axis motor 54 is placed at the upper end of the curved frame 53, and its head is mounted on the hanging plate 56. When in operation, it drives the relevant structures to rotate around the C-axis, giving the laser cutting head 59 the ability to adjust the circumferential angle. When facing special-shaped contour cutting, the cutting direction can be flexibly changed to ensure that the cutting path accurately fits the shape requirements. The B-axis motor 55 is located at the lower end of the curved frame 53 and drives the U-axis linear module 58 connected to the laser cutting head 59. The B-axis motor 55 rotates to adjust the tilt posture of the U-axis linear module 58 and the laser cutting head 59. Combined with the linear motion of the U-axis linear module 58 itself, multi-dimensional bevel cutting is achieved to meet the needs of complex process cutting. The hanging plate 56 is connected to the flat bottom plate 52 with the help of a leveling structure to compensate for the C-axis deviation caused by processing and installation errors, thereby ensuring the accuracy of C-axis movement.

[0039] The self-positioning sliding table 6 not only transports workpieces from outside the frame 1 to the cutting station inside, but also continuously supports the workpiece during the cutting process. Its self-positioning function utilizes precise mechanical structures, sensors, or a combination of both to ensure that the workpiece is accurately positioned at the preset cutting station position, accurately aligning it with the laser cutting head 59. Once the workpiece is in place, the various axis drive mechanisms work in tandem, controlling the laser cutting head 59 to perform complex and diverse cutting operations according to the preset cutting program, achieving high-precision machining.

[0040] From the perspective of the overall machine structure, the various components are tightly and rationally combined. By cleverly designing the relative positions of the crossbeam carriage 2, T-shaped slide 41, Z-axis square tube 51, and the multi-axis drive mechanism, motor, and module, the components required for complex multi-axis linkage cutting functions are efficiently integrated, reducing the overall space occupied by the equipment, meeting the requirements for direct container loading of the entire machine, reducing transportation costs, improving transportation efficiency, meeting the needs of international trade and transportation, and enhancing the product's international market competitiveness. With a complete X, Y, Z, B, C, and U-axis joint operation system, the laser cutting head 59 has flexible and variable movement. Whether it is a flat, irregular contour, a multi-dimensional bevel, or a complex cutting process that combines the two, the equipment is capable of handling it. This greatly expands the scope of cutting processes that can be handled, making it applicable to a variety of manufacturing scenarios, improving the versatility of the equipment, and reducing the cost investment of enterprises that need to purchase multiple equipment due to process limitations.

[0041] See also Figure 4 The leveling structure includes vertical screws 571 mounted on three corners of the flat base plate 52 and a universally rotatable ball joint bearing 576 mounted on the remaining corner. Through holes 562 are provided at the four corners of the suspension plate 56, through which the screw bodies of the three vertical screws 571 and the ball joint bearings 576 pass. Each vertical screw 571 is equipped with an upper adjustment nut 572 that presses against the top surface of the suspension plate 56, and each vertical screw 571 is equipped with a lower adjustment nut 573 that presses against the bottom surface of the suspension plate 56. The screw bodies of the ball joint bearings 576 are equipped with locking nuts 577 that securely connect the suspension plate 56 to the ball joint bearings 576. By adjusting the position of the upper and lower adjustment nuts 572, 573 on the vertical screws 571, the levelness of the suspension plate 56 can be precisely adjusted. The ball joint bearing 576 can adapt to a certain angular deviation, ensuring the flexibility and accuracy of leveling under different installation conditions and equipment operation processes, effectively solving the problem of posture changes of the C-axis motor 54 caused by manufacturing errors, installation deviations or equipment operation vibrations of the frame 1, and ensuring the high-precision operation of the laser cutting equipment.

[0042] In addition, the upper and lower joint support of the upper adjustment nut 572 and the lower adjustment nut 573 makes the connection between the suspension plate 56 and the vertical screw 571 more stable, and can effectively resist various external interferences during the operation of the equipment, preventing the suspension plate 56 from displacement or shaking. At the same time, the movable joint body of the ball joint bearing 576 is set on the flat bottom plate 52 through the positioning member 574, and the locking nut 577 on the screw body of the ball joint bearing 576 fixes the suspension plate 56 to the ball joint bearing 576, further enhancing the stability of the overall structure under complex working conditions, ensuring the reliable operation of the C-axis motor 54 and the cutting module and other components connected thereto during the laser cutting process, and improving the consistency of cutting quality.

[0043] Furthermore, a flat surface is provided between the upper adjustment nut 572 and the suspension plate 56. The flat surface evenly distributes the pressure applied by the upper adjustment nut 572 on the suspension plate 56. This prevents indentations or deformations on the surface of the suspension plate 56 due to excessive local pressure, reduces wear on the suspension plate 56, extends the service life of the suspension plate 56, and ensures long-term stable operation of the leveling structure.

[0044] Preferably, a spring medium 575 is provided between the lower adjustment nut 573 and the suspension plate 56. During operation, when the equipment is subjected to external vibrations or impacts generated by internal mechanical movement, the spring medium 575 acts as a buffer and shock absorber. It absorbs and disperses these impacts, reducing their impact on the leveling structure and its connected components, such as the C-axis motor 54 and the suspension plate 56. This prevents loosening, deformation, or damage to components caused by excessive impact, thereby ensuring the stability and reliability of the equipment, reducing the incidence of equipment failures, and improving operational safety.

[0045] For further information, see Figure 7 As shown, a flange ring 561 is provided at the relief opening 563 of the suspension plate 56, and the head of the C-axis motor 54 is connected to the flange ring 561. Compared to a simple direct connection, the flange ring 561 can evenly distribute the various forces exerted on the head, including its own gravity, the torque generated during operation, and the additional forces caused by vibration or other external factors during equipment operation. This uniform force distribution effectively reduces local stress concentration at the connection point, lowering the risk of loose connection or damage, and ensuring that the C-axis motor 54 can remain firmly mounted on the suspension plate 56 under long-term, high-intensity working conditions, thereby ensuring the stability of the overall structure and operational reliability of the laser cutting equipment.

[0046] Preferably, a downward-facing static pointer 578 is provided on the hanging plate 56, and a moving pointer 579 is provided on the bending frame 53. When the bending frame 53 rotates around the B-axis to the reference position, the static pointer 578 and the moving pointer 579 point to each other and align, which provides an intuitive and accurate reference positioning mark for the equipment. During the initial installation and commissioning stage of the equipment, the operator can quickly and accurately adjust the bending frame 53 to the standard reference position based on the alignment of the pointers, ensuring that the initial installation posture of the B-axis motor 55 and related cutting modules and other components meets the design requirements. During the long-term operation of the equipment, if the position of the bending frame 53 is offset due to equipment vibration, component wear or other reasons, by checking the relative position relationship between the static pointer 578 and the moving pointer 579, it can be discovered in time and recalibrated, effectively ensuring the positioning accuracy of the laser cutting equipment in each working stage, thereby improving the dimensional accuracy and quality stability of the cut products.

[0047] The Y-axis drive mechanism 3 of conventional laser cutting equipment specifically comprises a drive motor mounted on a support, with a gear mounted at the output end of the drive motor. This gear cooperates with the rack on the frame 1 to form a transmission, thereby driving the crossbeam to reciprocate along the guide rails of the frame 1, thereby enabling precise operation of the cutting head at different positions. However, this conventional design has significant drawbacks. In the past, the motor was often mounted toward one side of the support, for example, near the front of the crossbeam, resulting in uneven force during power transmission. During actual operation of the equipment, where the crossbeam frequently slides back and forth, the improper positioning of the drive motor can easily generate eccentric force during power transmission to the rack. This not only causes severe vibration during operation, significantly affecting cutting accuracy and causing defects such as jagged edges and burrs on the cut workpiece, reducing product quality, but also increases wear between the various components of the equipment, significantly reducing the equipment's service life and increasing maintenance costs and frequency. Furthermore, due to the uneven force, the smoothness of the crossbeam's forward and backward movement varies significantly. This instability becomes increasingly pronounced when cutting complex patterns and requiring frequent changes in movement direction, causing the cutting head to misalign and misalign, making it difficult to meet high-precision machining requirements. Furthermore, jitter and imbalance can affect the machine's operating speed. To avoid excessive cutting deviations caused by this shaking, the cutting speed often has to be reduced, severely limiting production efficiency.

[0049] During operation, the first motor 34 and the second motor 35 operate synchronously, each outputting torque that drives the connected first gear 341 and second gear 351 to rotate. Because the first motor 34 is positioned downward on the first flat base plate 222, between the two first wing plates 221, when viewed from the left, its axis coincides with the vertical center axis of the square crossbeam 21. Similarly, the layout of the second motor 35 when viewed from the right follows this principle. This layout ensures uniform and symmetrical power output. When the first gear 341 and the second gear 351 rotate, they mesh with the corresponding Y-axis rack 37 on the frame 1, pushing the crossbeam carriage 2 back and forth along the Y-axis guide rail 38, thereby precisely controlling the position of the cutting head and achieving the cutting operation. At the same time, a first slider 361 is provided on the bottom surface of the first flat base plate 222 of the first support 22, and a second slider 362 is provided on the bottom surface of the second flat base plate 232 of the second support 23. The Y-axis slider cooperates with the Y-axis guide rail 38 to assist the crossbeam carriage 2 in sliding smoothly, ensuring smooth movement. Furthermore, the vertical centerline of the square crossbeam 21 evenly divides the sliders, further ensuring that the first and second sliders 361, 362 are evenly loaded when carrying the weight of the crossbeam carriage 2 and transmitting the motor drive force. This symmetrical and evenly distributed design allows the two sides of the sliders to equally share the forces from the crossbeam and from operation, ensuring that the overall forces on the first and second sliders 361, 362 are balanced, significantly extending the service life of the sliders and reducing equipment downtime and maintenance time caused by slider damage.

[0050] The Y-axis drive mechanism 3 provided by the present invention forms a symmetrical motor layout on both sides by symmetrically placing the first motor 34 and the second motor 35 on the left and right end supports of the square crossbeam 21, and the motor axis coincides with the vertical center axis of the crossbeam slide 2, effectively solving the uneven force problem caused by the motor being installed to one side in the traditional design. Such a layout eliminates eccentric force at the power source, and the gear is evenly stressed during the transmission process of meshing with the rack, so that the crossbeam slide 2 can maintain a highly stable state throughout the entire reciprocating sliding stroke, without periodic shaking or offset due to uneven force. This greatly improves the consistency and stability of the sliding action, ensures the precise positioning of the cutting head, and is conducive to the processing of workpieces with complex shapes and high precision requirements.

[0051] The area between the two first wing plates 221 and enclosed by the first flat base plate 222 is the first transmission zone 223. The first wing plates 221 face away from the first motor 34 and enclose two mutually symmetrical first structural stabilization zones 224 with the first flat base plate 222. The first flat base plate 222 and the first wing plates 221 are reinforced at their intersection in the first structural stabilization zones 224 by a first triangular plate 225. This clever use of the principle of triangular structural stability significantly enhances the rigidity of the support, both locally and as a whole. When the crossbeam carriage 2 slides frequently or the equipment is subjected to prolonged vibration, the triangular plate effectively disperses and withstands stress from all directions, preventing deformation such as cracking and bending between the first wing plates 221 and the first flat base plate 222, stabilizing the support structure and providing a solid foundation for the smooth operation of the crossbeam carriage 2.

[0052] The design of two symmetrical first structural stabilization zones 224 ensures balanced force on both sides of the first support 22. This bilaterally symmetrical structure provides support when bearing the weight of the crossbeam carriage 2, the additional weight of the cutting head, and the inertial forces of motion. This prevents imbalance caused by excessive load on one side, eliminates support distortion, and maintains a horizontal and stable crossbeam position across all directions, meeting the stringent structural stability requirements of high-precision cutting equipment.

[0053] Furthermore, a third slider 363 is provided on the bottom surface of the first flat base plate 222, below the two first structural stabilization areas 224. The first slider 361 and the two third sliders 363 are arranged in parallel, forming a multi-point support system. As the crossbeam slide 2 slides along the Y-axis guide rail 38, they share the weight of the crossbeam slide 2 and the components above it, effectively dispersing the pressure and preventing uneven wear of the first slider 361 or localized compression deformation of the guide rail due to excessive weight at a single point. Compared to relying solely on a single first slider 361 for support, this layout provides a more balanced horizontal force on the crossbeam slide 2, significantly reducing the risk of shaking and deviation caused by uneven force, ensuring smooth, linear sliding of the crossbeam slide 2, and improving the positioning accuracy of the cutting operation.

[0054] Similarly, the area between the two second wing plates 231 and enclosed by the second flat seat plate 232 is the second transmission area 233. The second wing plates 231 face away from the second motor 35 and enclosed by the second flat seat plate 232 are two mutually symmetrical second structural stabilization areas 234. The second flat seat plate 232 and the second wing plates 231 are reinforced at their intersection in the second structural stabilization area 234 by a second triangular plate. The second flat seat plate 232 and the second wing plates 231 are reinforced at their intersection in the second structural stabilization area 234 by a second triangular plate, cleverly utilizing the principle of triangular structural stability to significantly enhance the rigidity of the support, both locally and as a whole. When the beam slides frequently and the equipment is in a long-term vibration condition, the second triangular plate can effectively disperse and withstand stress from all directions, preventing deformation such as cracking and bending between the second wing plates 231 and the second flat seat plate 232, stabilizing the support structure and providing a solid foundation for the smooth operation of the beam carriage 2.

[0055] The design of two symmetrical second structural stabilization zones 234 ensures balanced force on both sides of the second support 23. This bilaterally symmetrical structure provides a synergistic support when bearing the weight of the crossbeam carriage 2, the additional weight of the cutting head, and the inertial forces of motion. This prevents imbalance caused by excessive load on one side, eliminates support distortion, and maintains a horizontal and stable crossbeam position across all directions, meeting the stringent structural stability requirements of high-precision cutting equipment.

[0056] Similarly, a fourth slider 364 is provided on the bottom surface of the second flat base plate 232, below the two second structural stabilizing areas 234. The second slider 362 and the two fourth sliders 364 are arranged in parallel, forming a multi-point support system. As the crossbeam carriage 2 slides along the Y-axis guide rail 38, they share the weight of the crossbeam and the components above it, effectively distributing the pressure and preventing uneven wear of the second slider 362 or localized compression and deformation of the Y-axis guide rail 38 due to excessive weight at a single point. Compared to relying solely on a single slider for support, this layout provides a more balanced horizontal load on the crossbeam carriage 2, significantly reducing the risk of wobble and deviation caused by uneven force, ensuring smooth, linear sliding of the crossbeam carriage 2 and improving positioning accuracy during cutting operations.

[0057] For details, see Figure 1 and Figure 2As shown, the frame 1 includes four vertical beams 13 arranged in a rectangular shape, a first longitudinal beam 11 arranged on the top of the two vertical beams 13 on the left and extending forward and backward, and a second longitudinal beam 12 arranged on the top of the two vertical beams 13 on the right and extending forward and backward. The first longitudinal beam 11 and the second longitudinal beam 12 are parallel to each other and both are provided with a mounting plate 14 on the top surface. The mounting plate 14 is used for installing the Y-axis guide rail 38 and the Y-axis rack 37. An oil collecting tank body 15 is provided on the outer surface of the first longitudinal beam 11 and the second longitudinal beam 12, and a guide groove 141 for guiding the lubricating oil to flow to the oil collecting tank body 15 is opened on the mounting plate 14.

[0058] When lubricating the Y-axis guide rail 38, the lubricating oil will flow along the guide groove 141 opened on the mounting plate 14 to the oil collecting tank body 15 on the outer side of the first longitudinal beam 11 and the second longitudinal beam 12. When lubricating the Y-axis rack 37, the lubricating oil will directly drip into the oil collecting tank body 15, thereby achieving effective collection and guidance of the lubricating oil and preventing it from flowing everywhere.

[0059] The frame 1 structure provided by the present invention solves the problem of lubricating oil flowing freely, avoids the cleaning problem caused by lubricating oil contaminating the working area environment of the equipment, and maintains the cleanliness of the working environment. Since the lubricating oil is properly collected, the risk of it dripping onto the workpiece below is completely eliminated, ensuring that the workpiece is not contaminated by lubricating oil during the processing process.

[0060] The oil collecting tank 15 is provided with an oil drain valve 151, which facilitates the pumping and discharge of lubricating oil for centralized treatment or recycling after a certain amount of lubricating oil has been collected. This not only facilitates resource recycling, reduces lubricating oil waste, and lowers production costs, but also ensures that the oil collecting tank 15 always has a good oil storage capacity and maintains its effectiveness in collecting lubricating oil.

[0061] The rear ends of the first longitudinal beam 11 and the second longitudinal beam 12 are connected by a rear crossbeam, and the front ends of the first longitudinal beam 11 and the second longitudinal beam 12 are connected by an arched beam 171. The stability and rigidity of the overall structure of the frame 1 are improved by the reinforcement of the rear crossbeam and the arched beam 171. The design of the arched beam 171 serves to increase the height of the front of the frame 1, providing people with a more spacious and convenient entry space. During the daily maintenance and inspection of the equipment, operators can more easily enter the interior of the equipment and inspect, debug, repair or clean the various components located at the front end of the frame 1, such as the guide rails, racks, crossbeam slides 2 and cutting mechanisms. There is no need to bend over or operate with difficulty in a cramped space, which improves the efficiency and quality of maintenance work, reduces the extension of maintenance time caused by inconvenient operation and the risk of misoperation that may be caused, and helps to ensure the long-term stable operation of the equipment.

[0062] The bottoms of two adjacent vertical beams 13 are connected by a bottom beam 172, forming a stable bottom frame structure. During the operation of the laser cutting equipment, especially when facing large vibrations, shocks, or load changes, this bottom connection can effectively disperse and withstand forces from all directions, preventing the vertical beams 13 from displacement, shaking, or twisting deformation. This greatly improves the rigidity and stability of the overall structure of the frame 1, ensuring that the equipment can maintain precise operation under long-term, high-intensity working conditions, and providing a solid and reliable foundation for high-precision laser cutting operations.

[0063] For details, see Figures 12 to 14 As shown, the self-positioning sliding workbench 6 includes a base frame 61, a feeding slide 62 slidably arranged on the base frame 61, a working platform 63 arranged on the feeding slide 62, and a traction mechanism 64 for pulling the feeding slide 62 to move back and forth, the traction mechanism 64 includes a DC motor 641 fixed on the base frame 61, a reducer 642 driven by the DC motor 641, a driving sprocket 643 arranged on the output end of the reducer 642, a first driven sprocket 644 arranged on the front end of the base frame 61, and a second driven sprocket 645 arranged on the rear end of the base frame 61, the driving sprocket 643, the first driven sprocket 645 and the second driven sprocket 645. 4 and the second driven sprocket 645 form a transmission through a chain 646, and the two ends of the chain 646 are respectively connected to the feeding slide 62 through a tightening structure 65; a positioning block is provided on the feeding slide 62, and a front station 601 and a rear station 602 are provided on the base frame 61. A front stroke switch 671 that can be triggered by the positioning block is provided at the front station 601 to detect whether the feeding slide 62 has moved forward into place; a rear stroke switch 672 that can be triggered by the positioning block is provided at the rear station 602 to detect whether the feeding slide 62 has moved backward into place; a front locking structure 681 and a rear locking structure 682 for locking the positioning block that has moved into place are provided on the base frame 61.

[0064] When the workbench is activated for operation, DC motor 641 receives a control signal and begins to operate. The speed and torque characteristics of DC motor 641 are optimized and adjusted by reducer 642. Reducer 642 reduces the motor's high speed output while increasing its torque, producing a power output suitable for driving the feed carriage 62 smoothly. The driving sprocket 643 at the output end of reducer 642 rotates as the shaft of reducer 642 rotates. Because driving sprocket 643, a first driven sprocket 644 at the front end of base frame 61, and a second driven sprocket 645 at the rear end of base frame 61 are connected by chain 646 to form a complete transmission system, chain 646 begins to circulate, driven by driving sprocket 643. Both ends of the chain 646 are firmly connected to the feeding slide 62 through a specially designed tightening structure 65. The circular movement of the chain 646 is converted into a traction force on the feeding slide 62, prompting the feeding slide 62 to slide smoothly along the front and rear directions on the base frame 61, thereby realizing the switching of the feeding slide 62 between the front station 601 (cutting station) and the rear station 602 (non-cutting station).

[0065] As the feed carriage 62 slides on the base frame 61, the positioning block installed on the feed carriage 62 moves synchronously. As the feed carriage 62 moves toward the front station 601, the positioning block gradually approaches the area of ​​the front station 601. Once the positioning block enters the sensing range of the front travel switch 671 at the front station 601, the front travel switch 671 is immediately triggered, generating a corresponding electrical signal. This electrical signal is transmitted to the control system, which determines based on the signal that the feed carriage 62 has accurately moved forward to the working station, that is, the cutting processing position; after the front travel switch 671 detects that the feed carriage 62 has moved forward into position and sends a signal feedback, the pre-installed front locking structure 681 on the base frame 61 responds quickly. The front locking structure 681 accurately locks the positioning block that has moved into place through mechanical, electromagnetic or pneumatic means (depending on the specific design), ensuring that the feeding slide 62 will not be displaced at the front workstation 601 due to equipment vibration, slight elastic deformation of the chain 646 or other external force interference, providing stable platform support for cutting operations.

[0066] Conversely, when the feed carriage 62 moves backward to the rear station 602, the positioning block approaches the rear station 602, triggering the rear travel switch 672 at the rear station 602. The rear travel switch 672 also sends a signal to the control system indicating that the feed carriage 62 has moved back to its full position, and the feedback control system indicates that the feed carriage 62 has returned to the inactive loading and unloading position. When the rear travel switch 672 detects that the feed carriage 62 has moved back to its full position, the rear locking structure 682 is immediately activated, firmly securing the feed carriage 62 at the rear station 602, preventing the feed carriage 62 from accidentally moving during the loading and unloading process, thereby ensuring the operator's operational safety and the accuracy of workpiece loading and unloading.

[0067] When the feed slide 62 moves at high speed and approaches the end point of the workstation, the positioning block has a large amount of kinetic energy. For this reason, the base frame 61 is provided with a front buffer 691 and a rear buffer 692 for absorbing the kinetic energy of the positioning block when it is about to move into position. The provision of the front buffer 691 and the rear buffer 692 can effectively absorb the excess kinetic energy of the positioning block when it is about to move into position, preventing the positioning block from directly impacting the sensor, locking structure, or other related components on the base frame 61 due to inertia. This greatly reduces the risk of damage to these precision components caused by hard collisions, extends the service life of various components of the equipment, reduces the frequency and cost of equipment maintenance, and ensures the long-term stable and reliable operation of the entire self-positioning sliding workbench 6.

[0068] The front locking structure 681 includes a front limit block 6811 and a front corner pressing cylinder 6812. The pressure head of the front corner pressing cylinder 6812 presses the positioning block against the rear end surface of the front limit block 6811, thereby limiting the movement of the feed carriage 62. The rear locking structure 682 includes a rear limit block 6821 and a rear corner pressing cylinder 6822. The pressure head of the rear corner pressing cylinder 6822 presses the positioning block against the front end surface of the rear limit block 6821, thereby limiting the movement of the feed carriage 62. The front corner pressing cylinder 6812 and the rear corner pressing cylinder 6822 work in conjunction with the corresponding front limit block 6811 and rear limit block 6821 to achieve precise and stable mechanical locking of the positioning block once it has been moved into position. When the feeding slide 62 reaches the predetermined workstation, whether it is the front workstation 601 or the rear workstation 602, the corner downward pressure cylinder responds quickly, and its pressure head presses the positioning block tightly against the corresponding end face of the limit block with a large pressure, forming a stable friction force and blocking force, effectively limiting the accidental movement of the feeding slide 62 in any direction, ensuring that during the laser cutting operation (front workstation 601) or workpiece loading and unloading (rear workstation 602), the worktable is always in a precise fixed position, ensuring processing accuracy and operation safety.

[0069] The design combines a stop block with a corner push-down cylinder, resulting in a relatively compact overall structure. Compared to large, complex locking mechanical components, this design allows for a more rational layout within the limited installation space of the chassis 61. It does not occupy excessive chassis 61 surface area, impacting the installation and operation of other components, while efficiently completing the locking function and leaving ample space for other functional modules of the workbench, such as the traction mechanism 64 and sensors, thus ensuring the coordination and integrity of the entire workbench structure.

[0070] In this embodiment, the positioning blocks include a first sub-block 661 and a second sub-block 662, arranged side by side at the bottom of the feed carriage 62. The first sub-block 661 can trigger the front travel switch 671 and cooperate with the rear locking structure 682; the second sub-block 662 can trigger the rear travel switch 672 and cooperate with the front locking structure 681. After the workbench is started, the DC motor 641 rotates, driving the driving sprocket 643 through the reducer 642. The driving sprocket 643 drives the chain 646, which, via the tightening structure 65, drags the feed carriage 62 along the base frame 61 in a forward and backward direction. The first sub-block 661 and the second sub-block 662, arranged side by side at the bottom of the feed carriage 62, move synchronously with the movement.

[0071] When the workbench on the feed carriage 62 slides to the front station 601 and the first sub-block 661 triggers the front travel switch 671, the control system waits for the feed carriage 62 to fully position itself. At this point, the front locking structure 681 is activated, mechanically restricting the movement of the second sub-block 662. For example, the front limit block 6811 blocks the forward path of the second sub-block 662, and the pressure head of the front corner downward pressure cylinder 6812 presses down, pressing the second sub-block 662 against the front limit block 6811, laterally restricting the freedom of movement of the feed carriage 62 and ensuring the stability of the feed carriage 62 during cutting operations at the front station 601, preventing it from shifting due to external interference.

[0072] When the workbench on the feed carriage 62 slides to the rear station 602 and the second sub-block 662 triggers the rear travel switch 672, the rear locking structure 682 activates as the feed carriage 62 moves back into position. The rear limit block 6821 restricts the retreat path of the first sub-block 661, and the rear corner downward pressure cylinder 6822 presses the first sub-block 661 against the rear limit block 6821, preventing the feed carriage 62 from accidentally moving forward and ensuring safety and accuracy when loading and unloading workpieces at the rear station 602.

[0073] The first and second sub-blocks 661 and 662, respectively responsible for sensing and locking at different workstations, establish a dual positioning guarantee mechanism. This dual-position monitoring and control of the feed carriage 62's position allows for more accurate detection of its arrival at the intended workstation compared to a single positioning method. This effectively offsets positioning deviations caused by subtle errors in the chain 646 transmission and mechanical vibrations of the feed carriage 62 itself, providing extremely high positioning accuracy for precision machining processes like laser cutting, significantly improving product quality and reducing the likelihood of scrap.

[0074] This cross-locking design ensures that the feed carriage 62 is securely supported and restrained at both the front and rear workstations 602. At the front workstation 601, even if significant impact or vibration occurs during cutting, the front locking structure 681 firmly locks the second sub-block 662, preventing the feed carriage 62 from easily shaking. Similarly, during workpiece loading and unloading at the rear workstation 602, the rear locking structure 682's restraint of the first sub-block 661 ensures that the feed carriage 62 remains stationary, preventing accidents such as workpieces slipping or collisions. This significantly improves the worktable's operational stability under various operating conditions, reduces the risk of equipment failure, and ensures continuous production.

[0075] During the laser cutting process of hardware and automotive parts, a large amount of metal debris is generated. Therefore, a guard plate structure 603 is provided on the base frame 61 to effectively prevent the debris from flying around and falling into the areas where key transmission components and moving parts such as the feed carriage 62, chain 646, and guide rails are located.

[0076] It will be appreciated that the specific drive mechanism for the X-axis drive mechanism 42 and the Z-axis drive mechanism 50 is similar to that for the Y-axis drive mechanism 3 , with a drive motor driving the gears, and the gears and racks cooperating to form a transmission mechanism. The specific structure will not be described in detail here. To reduce the load on the Z-axis drive mechanism 50 that drives the Z-axis square tube 51 up and down, a downward-facing load-reducing cylinder 7 is provided on the T-shaped slide 41. The end of the piston rod of the load-reducing cylinder 7 is connected to the side of the Z-axis square tube 51.
