[0023] Before the machining center body 1 processes the workpiece, the sliding splash-proof cover 5 is installed on the lower side of the fixed splash-proof cover 4 through the quick-release assembly, so as to increase the splash-proof range, the machining head 3 is above the workpiece through the control of the horizontal and longitudinal movement of the machining column 2, the fixed splash-proof cover 4 and the sliding splash-proof cover 5 cover the workpiece at this time through the control of the vertical downward movement of the machining column 2, the sliding splash-proof cover 5 can slide in the fixed splash-proof cover 4, so as to avoid the limitation of the machining column 2 after the sliding splash-proof cover 5 abuts against the machining table when the machining head 3 does not contact the workpiece, thereby affecting normal processing, the splashed iron filings of the machining head 3 are shielded through the arrangement of the sliding splash-proof cover 5 and the fixed splash-proof cover 4, so as to realize the effect of preventing splashing, the splash-proof sleeve plates 7 and the splash-proof plug plates 8 can slide between the splash-proof sleeve plates 7 and the splash-proof plug plates 8 through the limiting support of the gantry 6, so as to enlarge the splash-proof area and height, and avoid the larger metal particles from being ejected due to unexpected situations, thereby causing potential harm to the surrounding personnel.

[0024] On the basis of example one, the fixed splash guard 4 is fixedly sleeved at the bottom of the machining column 2, and the fixed splash guard 4 facilitates the installation of the sliding splash guard 5. A limiting groove 9 is formed in the lower surface of the fixed splash guard 4, the limiting groove 9 limits the sliding splash guard 5, and facilitates the installation of the sliding splash guard 5. The limiting groove 9 and the sliding splash guard 5 are in sliding connection. The sliding splash guard 5 is provided with two and is symmetrically arranged about the center plane of the fixed splash guard 4. The symmetrically arranged sliding splash guard 5 facilitates the disassembly and replacement of the sliding splash guard 5. The limiting groove 9 is fixedly connected with the bumper 10 at the top side inner wall. The other end of the bumper 10 is in abutment with the upper surface of the sliding splash guard 5. The bumper 10 is arranged in the limiting groove 9. The sliding splash guard 5 extrudes the bumper 10, thereby adjusting the overall height of the fixed splash guard 4 and the sliding splash guard 5, thereby facilitating the adaptation to the machining of workpieces of different heights. The sliding splash guards 5 are in sliding insertion between the abutment sides. The outer surface of the fixed splash guard 4 is provided with an arc-shaped hole 11. The outer surface of the sliding splash guard 5 is provided with a groove 12. The arc-shaped hole 11 and the groove 12 are both in square distribution. The inner wall of the groove 12 is fixedly connected with one end of the spring 13. The other end of the spring 13 is fixedly connected with the limiting block 14. The limiting block 14 is in sliding connection with the arc-shaped hole 11 and the groove 12.

[0025] Before machining, the sliding splash guard 5 needs to be installed on the fixed splash guard 4. The limiting block 14 is first pressed into the groove 12, and the limiting block 14 is extruded against the spring 13. At this time, the sliding splash guard 5 is limited by the limiting groove 9 and is slid into the bottom of the fixed splash guard 4. When the top of the sliding splash guard 5 is in abutment with the bumper 10, the limiting block 14 is at the arc-shaped hole 11. Through the reverse elastic force of the spring 13, the limiting block 14 is slid into the arc-shaped hole 11, thereby installing one sliding splash guard 5 in the fixed splash guard 4 through the limiting of the arc-shaped hole 11. Another sliding splash guard 5 is installed in sequence. During machining, the machining head 3 is above the workpiece. The fixed splash guard 4 and the sliding splash guard 5 are sleeved around the workpiece by controlling the vertical downward movement of the machining column 2. Since the sliding splash guard 5 is in sliding cooperation with the limiting block 14 through the arc-shaped hole 11, the sliding splash guard 5 can slide in the fixed splash guard 4, thereby avoiding the abutment of the sliding splash guard 5 against the machining table when the machining head 3 is not in contact with the workpiece, thereby limiting the machining column 2 and affecting normal machining. Furthermore, the sliding splash guard 5 and the fixed splash guard 4 are arranged to shield the splashed iron filings of the machining head 3, thereby achieving the effect of preventing splashing.

[0026] Example 3: Based on Example 2, the auxiliary splash-proof assembly further includes a handwheel 15. The handwheel 15 is fixedly connected to one end of the connecting shaft 16, and a gear 17 is fixedly sleeved on the other end of the connecting shaft 16. Rotation of the handwheel 15 causes the connecting shaft 16 to drive the gear 17 to rotate. Racks 18 mesh with the upper and lower sides of the gear 17, and the racks 18 mesh with the gear 17 for transmission. The connecting shaft 16 is rotatably sleeved inside the side of the gantry frame 6, and the gantry frame 6 limits the movement of the connecting shaft 16. The lower side of the rack 18... A splash guard 7 is fixedly connected to one side of the splash guard 7. The splash guard 7 has an insertion hole, which is used to cooperate with the splash guard 8. One side of the splash guard 8 is fixedly connected to one side of the rack 18 mentioned above. The other side of the rack 18 is slidably connected to the limiting rail 19. The limiting rail 19 is fixedly installed on the side wall of the gantry frame 6. The limiting rail 19 limits the rack 18, thereby improving the stability of the movement of the splash guard 7 and the splash guard 8. A connecting rod 20 is fixedly connected to one end of the splash guard 7, the splash guard 8 and the rack 18.

[0027] After the sliding splash guard 5 and the fixed splash guard 4 are set, the handwheel 15 is turned, which drives the gear 17 to rotate under the connection of the connecting shaft 16. The gear 17 then drives the racks 18 on its upper and lower sides to move in opposite directions. The racks 18 slide under the limit of the limit rail 19, thereby driving the splash guard sleeve 7 and the splash guard insert 8 to move in opposite directions through the connection of the connecting rod 20, thereby expanding the splash height and splash area. At the same time, the splash guard sleeve 7 and the splash guard insert 8 are made of transparent high-hardness plastic, which makes it easy to see the processing and avoids the risk of iron filings flying and breaking them in case of accidents, thus further preventing iron filings from flying.

[0028] In practical use, when using this gantry machining center to prevent metal filings from splashing, the workpiece is placed above the machining table. The machining head 3 is moved directly above the workpiece by the control column 2, and then descends vertically to cover the workpiece with the fixed splash guard 4 and the sliding splash guard 5. The sliding splash guard 5 can slide within the fixed splash guard 4 to adapt to different machining heights, and is easily installed and removed via a quick-release assembly. In the auxiliary splash guard assembly, turning the handwheel 15 drives the gear 17 and rack 18 to slide and unfold the splash guard sleeve 7 and splash guard insert 8, expanding the splash protection range and height. The entire splash guard device effectively blocks metal filings from splashing through the transparent, high-hardness plastic splash guard and auxiliary splash guard assembly, ensuring machining safety and practicality. Content not described in detail in this specification is prior art known to those skilled in the art.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
