[0015] By adopting the above technical solution, both the transverse and longitudinal slides are driven by direct-drive motors, which have high transmission efficiency, accurate positioning, and rapid dynamic response. The vertical drive screw drives the vertical slide to slide in the vertical direction, which has a simple structure, convenient assembly and maintenance, faster dynamic response, and higher structural stability.
[0016] Preferably, two dustproof covers are slidably connected to the base, and both ends of the longitudinal slide are fixedly connected to the two dustproof covers respectively. The two dustproof covers cover the longitudinal slide cavity. Two discharge grooves are provided on the base, located on both sides of the longitudinal slide cavity. The two discharge grooves extend along the length of the base, and one end of the two discharge grooves near the protective seat penetrates through the base.
[0017] By adopting the above technical solution, the two dust covers slide synchronously with the longitudinal slide block, thus forming a complete shielding and protection for the longitudinal slide cavity throughout the entire movement. The debris and coolant generated during the processing can slide directly down the dust covers into the discharge chute, where they can be cleaned by the staff. The dust covers can effectively prevent dust, debris and moisture from entering the interior of the longitudinal slide cavity, avoiding jamming and corrosion of precision moving parts such as the longitudinal stator and longitudinal mover, ensuring smooth and stable sliding movement, improving the operating accuracy of the equipment, reducing the probability of failure, and effectively extending the service life of the core transmission components.
[0018] Preferably, the base has two sliding cavities, which are arranged along the length of the base. Two sliding openings are formed between the two sliding cavities and the two discharge grooves, which are used to connect the sliding cavities and the discharge grooves.

When too much debris accumulates in front, the side of the first pusher plate near the discharge chute is blocked by resistance, causing the first pusher plate to tilt in the direction of the resistance. The side of the first pusher plate away from the discharge chute forms a downward pressure on the waste, thereby pushing the waste out of the discharge chute.

[0021] By adopting the above technical solution, during the material pushing operation, the pusher seat can slide flexibly along the discharge chute, always maintaining a close fit with the discharge chute, preventing waste material from overflowing from the bottom of the first pusher plate, eliminating waste residue, and ensuring thorough cleaning with each push. Simultaneously, under the elastic limiting action of the tension spring, the distance between the pusher seat and the first pusher plate can be stabilized, preventing the plug-in block from dislodging from the pusher plate cavity due to waste resistance, ensuring stable and reliable operation of the pusher structure.

[0023] By adopting the above technical solution, the second pusher plate cleans and scrapes away machining debris and coolant from the surface of the longitudinal slide block, and the pusher block cleans and scrapes away machining debris and coolant from the T-slot, effectively preventing debris accumulation. When the pusher block moves to its limit stroke position, the second pusher plate can rotate through the hinge, ensuring stable and smooth machining operations.
[0024] Preferably, a second driving cavity is provided on the inner wall of the T-shaped groove near the support base. The second driving cavity is connected to the T-shaped groove. A second driving member is installed in the second driving cavity. The second driving member is used to drive the pusher block to reciprocate along the width direction of the longitudinal slide block.
[0025] By adopting the above technical solution, the second driving component directly drives the pusher block, the transmission structure is simple and compact, the response is faster, the pusher block slides smoothly, and the material cleaning operation can be completed stably, effectively improving the overall chip removal effect and enhancing the reliability of equipment operation.
[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. During operation, the workpiece is first loaded into the loading chamber and placed on the longitudinal slide block for secure mounting. After loading, the CNC program is activated. The transverse, longitudinal, and vertical drive structures drive the transverse, longitudinal, and vertical slide blocks in a three-axis linkage, precisely adjusting the working position of the turning drill to ensure accurate alignment with the workpiece machining area. The coordinated operation of these drive structures enables automated three-axis machining of the workpiece. The loading and unloading chambers effectively expand the loading and unloading operation range, simplify the loading and unloading process, reduce operational difficulty, and significantly improve workpiece changing efficiency and overall production efficiency. 2. During the material pushing operation, the pusher seat can slide flexibly along the discharge chute, always maintaining a tight fit with the discharge chute to prevent waste material from overflowing from the bottom of the first pusher plate, eliminating waste residue and ensuring thorough cleaning with each push. Simultaneously, the elastic limiting action of the tension spring stabilizes the distance between the pusher seat and the first pusher plate, preventing the insert block from dislodging from the pusher plate cavity due to waste resistance, thus ensuring stable and reliable operation of the pusher structure. 3. The two dust covers slide synchronously with the longitudinal slide block, thus providing complete shielding and protection for the longitudinal slide cavity throughout the entire movement process. The debris and coolant generated during processing can slide directly down the dust covers into the discharge chute, where they can be cleaned by the staff. The dust covers can effectively prevent dust, debris, and moisture from entering the longitudinal slide cavity, avoiding jamming and corrosion of precision moving parts such as the longitudinal stator and longitudinal mover, ensuring smooth and stable sliding movement, improving equipment operating accuracy, reducing the probability of failure, and effectively extending the service life of core transmission components.

[0028] The following is in conjunction with the appendix Figure 1 - Figure 9 This application will be described in further detail.
[0029] This application discloses a semi-open three-axis machining center.
[0030] Example 1 Reference Figure 1 and Figure 2A semi-open three-axis machining center includes a base 7, a support seat 13 mounted on the base 7, a transverse slide 10 slidably connected to the support seat 13, a transverse drive structure for driving the transverse slide 10 to slide, the transverse slide 10 sliding laterally along the X-axis, a vertical slide 9 slidably connected to the transverse slide 10, the vertical slide 9 sliding along the Z-axis, a vertical drive structure for driving the vertical slide 9, and a turning drill mounted at the bottom of the vertical slide 9 for turning the workpiece; the support seat...

A protective cavity 29 is opened in the protective seat 27, and a tank chain 14 is installed in the protective cavity 29. The protective cavity 29 is connected to the processing cavity 15. One end of the tank chain 14 is fixedly connected to the longitudinal slide 5, and the other end is installed in the protective cavity 29. The protective cavity 29 is used to accommodate and protect the tank chain 14, providing sufficient displacement space for the tank chain 14 to reciprocate with the longitudinal slide 5. The tank chain 14 can form an orderly storage and directional constraint on the internal cables. The tank chain 14 moves synchronously with the longitudinal slide 5 to prevent the cables from being excessively bent, pulled or tangled, while blocking dust and debris from entering, ensuring the service life of the cables and the movement accuracy of the equipment, and improving the overall layout neatness and maintenance convenience.
[0032] A baffle plate 1 is installed on the base 7. A baffle cavity 4 is opened on the baffle plate 1. A waterproof curtain 3 is installed in the baffle cavity 4. The chain-type tool magazine 2 is set through the baffle cavity 4. This structural design can effectively isolate machining chips, dust and cutting fluid, avoid corrosion and wear of moving parts such as tool magazine chain, reduce jamming failures, reduce the frequency of daily maintenance and maintenance costs, ensure continuous and stable machining of machine tool, and improve the reliability of the whole machine operation.
[0033] Reference Figure 4The chain tool magazine 2 has a tool magazine base installed at its bottom, which is slidably connected to the chain tool magazine 2. Two tool holder slide rods 42 are mounted on the tool magazine base, extending along the length of the chain tool magazine 2. Multiple tool holder sliders 43 are mounted at the bottom of the chain tool magazine 2, sliding in conjunction with the tool holder slide rods 42. A drive cylinder 41 is mounted on the tool magazine base, driving the chain tool magazine 2 to slide along the length of the tool holder slide rods 42. When a tool change is needed, the drive cylinder 41 drives the chain tool magazine 2 to slide, causing the chain tool magazine 2 and the transverse slide block 10 to slide relative to each other in a direction of closer proximity. This effectively reduces tool change time, improves tool change efficiency, and thus enhances machining efficiency.
[0034] The transverse drive structure includes a row of transverse stators 12 mounted on the support base 13. A row of transverse movers 11 is mounted on the side of the transverse slide 10 near the transverse stators 12. The transverse movers 11 and the transverse stators 12 are electromagnetically coupled to realize the sliding movement of the transverse slide 10. The vertical drive structure includes a vertical drive cavity opened on the transverse slide 10. A vertical drive screw 23 is installed in the vertical drive cavity. A vertical drive motor 22 is installed at the end of the vertical drive screw 23 away from the base 7. The vertical drive motor 22 drives the vertical drive screw 23 to rotate. A screw sleeve 24 is sleeved on the vertical drive screw 23. The screw sleeve 24 is fixedly installed on the vertical slide 9. The screw sleeve 24 slides vertically on the screw, thereby driving the vertical slide 9 to perform vertical reciprocating sliding movement. The longitudinal drive structure includes a longitudinal slider 18 mounted on the bottom of the longitudinal slide block 5, and a longitudinal slide cavity 17 on the base 7 that slides and engages with the longitudinal slider 18. Two rows of longitudinal stators 20 are installed within the longitudinal slide cavity 17. Two rows of longitudinal movers 19 are mounted on both ends of the longitudinal slider 18 near the two rows of longitudinal stators 20. The longitudinal movers 19 and the longitudinal stators 20 are electromagnetically engaged to achieve the sliding of the longitudinal slide block 5. Both the transverse slide block 10 and the longitudinal slide block 5 are driven by direct-drive motors, resulting in high transmission efficiency, precise positioning, and rapid dynamic response. The vertical drive screw 23 drives the vertical slide block 9 to slide vertically, resulting in a simple structure, convenient assembly and maintenance, faster dynamic response, and higher structural stability.
[0035] Two dustproof covers 6 are slidably connected to the base 7. Each dustproof cover 6 is composed of multiple dustproof sheets that overlap and cooperate to form a retractable and sliding structure. The two ends of the longitudinal slide block 5 are fixedly connected to the two dustproof covers 6 respectively. The two dustproof covers 6 cover the longitudinal sliding cavity 17 and slide synchronously with the longitudinal slide block 5, thus providing complete shielding and protection for the longitudinal sliding cavity 17 throughout the entire movement. Two discharge grooves 21 are provided on the base 7. The two discharge grooves 21 are located on both sides of the longitudinal sliding cavity 17 and extend along the length of the base 7. The discharge trough 21 extends in the direction and is set through the base 7 at one end near the protective seat 27. It can receive the debris and cooling liquid generated during the processing, so that the production waste flows into the discharge trough 21 along the outer wall of the dust cover 6. The dust cover 6 can effectively block dust, debris and water vapor from entering the interior of the longitudinal sliding cavity 17, avoid jamming and corrosion of precision moving parts such as the longitudinal stator 20 and the longitudinal mover 19, ensure smooth and stable sliding movement, improve the operating accuracy of the equipment, reduce the probability of failure, and effectively extend the service life of the core transmission components.
[0036] The implementation principle of a semi-open three-axis machining center according to this application embodiment is as follows: During operation, the workpiece to be processed is placed on the longitudinal slide 5 and fixedly installed; the opening of the material cavity provides sufficient operating space for loading and unloading. Before starting the equipment, it is necessary to check whether the telescopic part of the dust cover 6 is normal, and ensure that it will not jam when it moves with the longitudinal slide 5. After loading is completed, the preset CNC program is started, and each slide moves under the drive of the corresponding drive component, adjusting its position according to the workpiece processing requirements, and cooperating to complete the three-axis linkage machining of the workpiece. During the processing, the chips and coolant generated by cutting will flow directly into the discharge trough 21 along the outer wall of the dust cover 6. After the waste in the discharge trough 21 reaches a certain height, it is cleaned by the staff. When the equipment is running, the cable in the tank chain 14 is perfectly protected, neither corroded by coolant nor contaminated by cutting chips, effectively extending the service life of the cable. If tool replacement is required during processing, it can be fully automated via the chain-type tool magazine 2. The waterproof curtain 3 inside the material-holding chamber 4 effectively protects the tool heads on the chain-type tool magazine 2 from contamination by coolant and other contaminants, extending tool head life and reducing costs. After processing, each slide returns to its original position, the fixed seat releases the workpiece, and the operator quickly unloads the workpiece, achieving continuous and efficient processing. Throughout the entire processing process, all protective components work together to effectively protect the cables and the chain-type tool magazine 2, ensuring stable equipment operation and successful precision machining of the workpiece. The material chamber design expands the operating space of the robotic arm, making workpiece loading and unloading operations more convenient and improving the overall operating efficiency and processing production efficiency of the equipment.
[0037] Example 2 Referring to Figure 5, the difference between this embodiment and Embodiment 1 is that two sliding cavities 37 are formed on the base 7, and the two sliding cavities 37 are arranged along the length of the base 7. Two sliding openings 36 are formed between the two sliding cavities 37 and the two discharge grooves 21, and the sliding openings 36 are used to connect the sliding cavities 37 and the discharge grooves 21. Two first screws 32 are rotatably connected inside the two sliding cavities 37. The ends of the two first screws 32 near the protective seat 27 pass through the base 7 and are each equipped with a first drive motor 31, which drives the first screws 32 to rotate. Two sliding blocks 33 are slidably connected to the two first screws 32. The sliding blocks 33 pass through the sliding openings 36 and are set in the discharge grooves 21. Two first push plates 34 are hinged to the two sliding blocks 33, and the first push plates 34 are used to push out production debris and cooling liquid generated during processing. During the pushing process, the rotation of the first screws 32 drives the sliding blocks 33 to slide, and the sliding blocks 33 synchronously drive the first push plates 34 to move. When too much debris accumulates in front, the side of the first pusher plate 34 closest to the discharge trough 21 is blocked by resistance, causing the first pusher plate 34 to tilt in the direction of the resistance. The side of the first pusher plate 34 away from the discharge trough 21 exerts downward pressure on the waste, thereby pushing the waste out of the discharge trough 21.
[0038] Reference Figure 6 A pusher seat 38 is slidably connected inside the discharge trough 21, and a pusher plate cavity 39 is formed on the inner side of the pusher seat 38. A rectangular insert block 40 is integrally formed at one end of the first pusher plate 34 near the discharge trough 21, and the insert block 40 is inserted into the pusher plate cavity 39. A telescopic spring 25 is installed between the pusher plate cavity 39 and the insert block 40, limiting the distance between the pusher seat 38 and the first pusher plate 34. During the pushing operation, the pusher seat 38 can slide flexibly along the discharge trough 21, always maintaining a tight fit with the discharge trough 21, preventing waste material from overflowing from the bottom of the first pusher plate 34, eliminating waste residue, and ensuring thorough cleaning with each pushing operation. Meanwhile, under the elastic limiting action of the extension spring 25, the distance between the pusher seat 38 and the first pusher plate 34 can be stabilized, preventing the plug block 40 from being dislodged from the pusher plate cavity 39 due to the resistance of the waste material, thus ensuring the stable and reliable operation of the pusher structure.
[0039] Reference Figure 7A second pusher plate 26 is mounted on the longitudinal slide 5. The second pusher plate 26 is a rectangular plate and is arranged along the length of the longitudinal slide 5. Multiple pusher blocks 28 are hinged to the second pusher plate 26. The pusher blocks 28 are T-shaped. Multiple T-shaped grooves 35 are evenly spaced on the longitudinal slide 5. The multiple T-shaped grooves 35 are slidably connected to the multiple pusher blocks 28. The pusher blocks 28 are used to discharge machining debris and coolant from the T-shaped grooves. Multiple limiting grooves 30 are provided on the longitudinal slide 5. The multiple limiting grooves 30 are connected to the multiple T-shaped grooves. The limiting grooves 30 are used to limit the maximum pushing stroke of the pusher blocks 28 and prevent the pusher blocks 28 from slipping off. The second pusher plate 26 cleans and scrapes away machining debris and coolant from the surface of the longitudinal slide 5, and the pusher blocks 28 clean and scrape away machining debris and coolant from the T-shaped grooves 35, effectively preventing debris accumulation. When the pusher block 28 moves to its limit stroke position, the second pusher plate 26 can rotate through the hinge to ensure that the processing procedure is stable and smooth.
[0040] Reference Figure 8 and Figure 9 A second driving cavity 45 is formed on the inner wall of the T-shaped groove 35 near the support base 13. The second driving cavity 45 is connected to the T-shaped groove 35, and a second driving component 44 is installed in the second driving cavity 45. The second driving component 44 is used to drive the pusher block 28 to reciprocate sliding along the width direction of the longitudinal slide block 5. The pusher block 28 is directly driven by the second driving component 44. The transmission structure is simple and compact, the response is more sensitive, the pusher block 28 slides smoothly and has high guiding accuracy, which can stably complete the cleaning operation, effectively improve the overall chip removal effect, and enhance the reliability of equipment operation.
[0041] The implementation principle of Example 2 is as follows: During the workpiece processing, the equipment continuously generates processing debris and cooling waste liquid. Some debris will fall onto the T-slot 35 and the upper surface of the longitudinal slide block 5. When debris and waste liquid accumulate in the discharge trough 21, the first drive motor 31 drives the first screw 32 to rotate, thereby driving the sliding block 33 and the first pusher plate 34 to slide and push the material along the length of the discharge trough 21. During the pushing operation, the pusher seat 38 can slide flexibly along the discharge trough 21, always keeping it in close contact with the discharge trough 21 to prevent waste from overflowing from the bottom of the first pusher plate 34, eliminating waste residue and ensuring thorough cleaning of each push. When debris and waste liquid remain on the surface of the longitudinal slide block 5 and in the T-slot 35, the second drive component 44 drives the pusher block 28 to slide back and forth along the T-slot 35 to clean the debris and coolant in the trough. At the same time, the second pusher plate 26 scrapes off and discharges the waste material and waste liquid from the surface of the longitudinal slide block 5. When the pusher block 28 reaches its limit stroke, the second pusher plate 26 can rotate along the hinge to avoid it, ensuring smooth operation of the machining process. The entire machining center can simultaneously complete automated chip removal and contamination removal during the machining process, effectively preventing waste accumulation and maintaining long-term stable operation of the equipment.
