It should be further explained that a lead screw support rod and a nut are arranged above the concrete base 1 to support the side beam 2, so that the side beam 2 can be fine-tuned in the up and down directions by adjusting the nut on the lead screw support rod for fine-tuning movement. A cross beam 5 is arranged across the side beam 2, and a middle frame is arranged on the cross beam 5, and a guide The guide column 15 and the two ends of the four guide columns 15 are respectively provided with mounting plates 16. A saw slide screw rod 14 is arranged above the middle frame and passes through the mounting plate 16 above. A saw slide reducer 17 is arranged on the mounting plate 16 above. The specific description is as follows: the structure of the guide column 15 and the mounting plate 16 greatly improves the rigidity of the spindle saw 26. The spindle saw 26 moves along the crossbeam 5. The saw blade 9 has a large processing space. The large space above the mounting plate 16 can be used to install a high-power motor, which provides convenient conditions for hanging a large saw blade 9 on the spindle saw 26, thereby increasing the cutting depth. Furthermore, the saw slide reducer 17 drives the sliding cooperation between the guide column 15 and the middle frame through the spiral cooperation of the fixedly connected nut and the saw slide screw rod 14, and the middle frame adopts a screw Drive, eliminates the positioning error of hydraulic drive, and improves the accuracy of four-sided cutting and drilling, milling and polishing; a spindle saw 26 is arranged on the mounting plate 16 at the bottom, and a spindle saw motor 29 is also arranged on one side of the mounting plate 16 at the top, a saw blade 9 is arranged at one end of the spindle saw 26, a back cross plate 10 is arranged on one side of the mounting plate 16, and a drilling, milling and polishing mechanism is arranged on one side of the back cross plate 10, and the drilling, milling and polishing mechanism includes a drilling, milling and polishing slide 11, and a drilling, milling and polishing slide guide rail 21 is arranged at one side corner of the drilling, milling and polishing slide 11, a drilling, milling and polishing slide screw is arranged between the two drilling, milling and polishing slide guide rails 21, a drilling, milling and polishing slide slider 18 is arranged on the back cross plate 10 corresponding to the drilling, milling and polishing slide guide rail 21, and a back cross plate corresponding to the drilling, milling and polishing slide screw is arranged. 10 is provided with a drilling, milling and polishing slide nut 19, and a drilling, milling and polishing power head 22 is provided on the other side of the drilling, milling and polishing slide 11. The specific description is: for the established drilling, milling and polishing power head 22, it is an existing mature technology and has good drilling, milling and polishing functions. It is established together with the center cutting saw. Under the premise of not affecting the use of the center cutting saw, it effectively improves the functionality of the device and equipment and ensures the working progress. By utilizing the cooperation between the established drilling, milling and polishing slide screw and the drilling, milling and polishing slide nut 19, it can drive the drilling, milling and polishing slide 11 to be lifted and moved in the vertical direction. In this way, when using the drilling, milling and polishing function, the drilling, milling and polishing power head 22 can be adjusted to the bottom of the center cutting saw blade 9 to ensure the normal use of the drilling, milling and polishing function and meet the use requirements.

[0032] In order to further ensure that the device has good practicality and effectively ensure the stability of the middle frame during movement, a middle frame anti-sway guide rail 12 is provided at the lower corner of the outer side of the middle frame, and a middle frame anti-sway slider 13 is provided on the inner side of the middle frame corresponding to the middle frame anti-sway guide rail 12, that is to say: the middle frame anti-sway slider 13 is mounted on the middle frame anti-sway guide rail 12, and the two are slidably connected. This design reduces the sliding gap between the two, which can offset the upward force generated during the sawing process, reduce the up and down swing error of the middle frame, and thus improve the processing accuracy.

[0033] In order to ensure that the middle frame can move laterally along the crossbeam 5, a crossbeam rack 24 is arranged inside the crossbeam 5, and crossbeam V-rails 23 are arranged on both sides of the crossbeam rack 24. A middle frame driving reducer is also arranged above the middle frame. Specifically, a V-shaped slider matched with the crossbeam V-rail 23 is set at the lower inner side of the middle frame to ensure the coordination effect between the two and improve the operation stability. At the same time, a driving gear is arranged at the output end of the hollow driving reducer and meshed with the crossbeam rack 24 to ensure the effective transmission of driving power and meet the functionality.

[0034] In order to further improve the rationality of the device, cross beam locking beam blocks 4 are arranged on both sides of the middle frame, and side beam slide plates 3 are arranged below the cross beam locking beam blocks 4, and are slidably connected with the top of the side beam 2. The specific description is: a screw guide drive is arranged above the side beam 2 to drive the cross beam locking beam block 4 to move and adjust in the longitudinal direction. This design eliminates the backlash of the existing conventional rack drive and improves the processing accuracy of four-sided cutting and drilling, milling and polishing. At the same time, this design also effectively improves the rigidity and stability of the device and equipment, ensures the effective progress of production and processing, and meets the use requirements.

[0035] In order to effectively improve the practicality of the device and relatively extend its service life, a turntable 6 is arranged between the two concrete bases 1. The selected turntable 6 can rotate 360 ​​degrees in the circumferential direction to drive the workpiece to complete different cutting tasks and ensure the work progress. A steel plate 25 is arranged above the turntable 6, and a marble plate 7 is arranged above the steel plate 25. It is specifically described as follows: the marble plate 7 used has the advantages of high hardness, not easy to deform and high adjustment accuracy, which is convenient for manual rapid adjustment of its flatness during installation. Furthermore, in order to ensure that the marble plate 7 is not easy to bend, the steel plate 25 is set under the marble plate 7, which increases the overall toughness and anti-bending ability of the platform to a certain extent, and increases the load capacity of the workpiece, effectively meeting the use requirements.

[0036] In order to ensure that the device has good functionality, especially to ensure that the turntable 6 can still maintain the uniformity of the mechanical origin after driving the workpiece to rotate, mechanical origin switch sensing sheets 28 are provided on the outer sides of the side beams 2 and the outer sides of the cross beams 5 and at the geometric center of the turntable, a first mechanical origin switch 27 corresponding to the side beams 2 is provided on the outer sides of the side beam slide plates 3, and a second mechanical origin switch 27 corresponding to the cross beams 5 is provided in the middle frame. Specifically, the mechanical origin switch sensing sheets 28 are installed on the side beams 2 and the cross beams 5, and the mechanical origin switches 27 are provided on the side beam slide plates 3 and the middle frame. When the mechanical origin switch 27 senses the mechanical origin switch sensing sheets 28, the mechanical origin can be set on the side beams 2 and the cross beams 5. The mechanical origin coincides with the geometric center of the turntable 6, so that the origin remains unchanged after each 90-degree rotation of the turntable 6. Therefore, when four-sided cutting is performed, the next side can be automatically cut by turning 90 degrees after cutting one side, without the need to redefine the origin. Therefore, four-sided cutting can be fully automated without manual intervention, thereby improving efficiency. Furthermore, the workpiece is placed on the turntable 6, cut once, then turned 180 degrees and cut again. The middle position of the two knife marks is the mechanical origin of the side beam 2. After turning 90 degrees and cutting once, turn 180 degrees and cut again. The middle position of the two knife marks is the mechanical origin of the crossbeam 5. After determining the mechanical origin, the mechanical origin switch sensor 28 is placed to record the centered mechanical origin, thereby ensuring that the mechanical origin is absolutely centered on the geometric origin of the turntable and that the mechanical origin is unique each time.

[0037] In the above process: the turntable 6 is set up as a matching structure of a steel plate 25 and a marble plate 7, and the steel plate is fixedly connected under the marble platform, which increases the toughness of the marble platform while retaining the high precision and non-deformation characteristics of the marble platform. The marble platform can also be made thin, which indirectly increases the load capacity of the workpiece of the 360-degree turntable 6; the origin is placed in the geometric middle position of the turntable between the side beam 2 and the cross beam 5, and the origin remains unchanged after each 90-degree rotation of the turntable 6. When cutting on four sides, it can automatically rotate 90 degrees to cut the next side after cutting one side, and there is no need to re-determine the origin, so that fully automatic four-side cutting can be achieved without manual intervention, thereby improving efficiency; the structure of the middle frame guide column 15 is adopted, and the four-side cutting rotating part abandons the five-axis structure, and adopts the structure of the 360-degree hydraulic motor turntable 6, so that the spindle saw can be installed with a large saw blade, and the spindle saw motor has a large installation space and high power. , ensuring the effective cutting depth of the sawing work; the side beam 2 adopts a guide rail screw, and the Z-axis of the saw adopts a screw with high precision; a new cross plate is added to the rear side of the middle frame, and the back cross plate 10 is slidably connected to the drilling, milling and polishing slide 11, which can realize drilling, milling and polishing, and the workpiece can be formed at one time without manual movement to other machine tools to complete subsequent processing, reducing the number of transportation times, improving efficiency and reducing equipment costs; a guide rail is fixed on the front and back sides of the cross beam 5, and the middle frame fixes the slider.
