[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0043] Please refer to Figures 1-10 , a vertical machining center provided in this embodiment includes a processing table 1 and a Y-axis substrate 11 that moves vertically on the processing table 1. Both the processing table 1 and the Y-axis substrate 11 are existing vertical machining devices. In addition, a substrate for driving the workpiece to move in the X and Z axes is provided on the processing table 1. Its structure is the basic part of the vertical machining center, and the connection method between its substrates is also the prior art, which will not be elaborated here. A liquid storage cylinder 12 is fixedly connected to the Y-axis substrate 11. The liquid stored in the liquid storage cylinder 12 is coolant. A disc 13 is rotatably connected to the outside of the liquid storage cylinder 12, and a processing component is provided on the disc 13; a water spraying component and a chip removal component are also included, which are arranged on the disc 13; during processing, the position of the water spraying component is adaptively adjusted through a triggering mechanism to spray water for cooling and dust removal at different depths of the aperture at the processing location, and the chip removal component adsorbs and collects the splashed chips as it moves with the processing component. When the processing component processes the workpiece on the processing table 1, the top of the workpiece will contact the triggering mechanism. As the processing component penetrates deeper into the workpiece, the triggering mechanism is affected by the top of the workpiece and triggers the water spraying component to adaptively adjust its position, facilitating cooling of apertures at different depths, and cooperating with the chip removal component to adsorb the splashed iron chips to prevent iron chip accumulation from affecting the normal operation of the processing component.

[0044] In an embodiment further provided by the present invention, the water spraying assembly includes a water pipe 21 communicated with the liquid storage cylinder 12. A water outlet nozzle 22 is communicated with the water pipe 21. Damping rods 23 are fixedly connected to both sides of the water outlet nozzle 22. The water outlet nozzle 22 is arranged on one side of the processing assembly. A water pump is arranged in the liquid storage cylinder 12, which can introduce the liquid inside the liquid storage cylinder 12 into the water outlet nozzle 22 through the water pipe 21 and spray it out to cool and remove dust from the processing area. In the initial state, the water outlet nozzle 22 is arranged obliquely so as to spray water obliquely on the processing area and can also spray away the waste chips generated during processing.

[0045] In an embodiment further provided by the present invention, the triggering mechanism includes a plurality of first telescopic rods 31 slidably connected to the disc 13. The same top plate 32 is fixedly connected to the plurality of first telescopic rods 31. Two rectangular cylinders 33 slide horizontally on the top plate 32. Moving plates 34 are slidably connected in the two rectangular cylinders 33. Support springs 35 are fixedly connected between each moving plate 34 and the corresponding rectangular cylinder 33. Long rods 36 are fixedly connected to both moving plates 34. Rack plates 37 are fixedly connected to both long rods 36. First gears 38 are fixedly connected to both damping rods 23. The two rack plates 37 are respectively engaged with the corresponding first gears 38 during the movement stroke. The two telescopic rods are both provided with guiding components, and the two moving plates 34 are also provided with a pushing component for driving the corresponding resistance rods to move. By providing the first telescopic rods 31 and the top plate 32, the rectangular cylinders 33 are fixedly supported. And the two rectangular cylinders 33 are respectively arranged on both sides of the processing assembly. When the rack plate 37 moves into contact with the first gear 38 and drives it to rotate, it will drive the damping rods 23 on both sides of the water outlet nozzle 22 to rotate, so as to adjust the angle of the water outlet nozzle 22, so as to spray water on the processing areas at different depths. Until the rack plate 37 engages with the first gear 38 and cooperates with the damping rod 23 to drive the water outlet nozzle 22 to be perpendicular to the top of the workpiece, at this time the rack plate 37 will be separated from the first gear 38, and the long rod 36 will contact the first gear 38. At this time, the first gear 38 does not rotate and maintains the state when it is separated from the rack plate 37 until the bottom of the rack plate 37 contacts the top of the workpiece and the rack plate 37 no longer moves downward, while the rectangular cylinder 33 is abutted and gradually moves downward by squeezing the support spring 35. When the processing assembly drills to a certain depth, when the water outlet nozzle 22 rotates close to the vertical, it will drive the water outlet nozzle 22 to move toward the processing assembly side under the cooperation of the pushing component and the guiding component, so that the water outlet nozzle 22 can move above the hole for spraying water. Wherein the elastic force of the support spring 35 is greater than the resistance between the rack plate 37 and the first gear 38.

[0046] Further, the guiding component includes a side plate 41 fixedly connected to the first telescopic rod 31. A track groove 42 is formed in the side plate 41. A limiting rod 43 is fixedly connected to the toothed plate 37, and the limiting rod 43 is slidably connected in the track groove 42. A limiting frame 44 is fixedly connected to the side plate 41, and a moving block 45 is slidably connected in the limiting frame 44. The damping rod 23 is rotatably connected in the moving block 45. When the processing component contacts the top of the workpiece, the side plate 41 provided on the first telescopic rod 31 will contact the top of the workpiece. As the Y-axis substrate 11 drives the continuous downward movement of the processing component, the first telescopic rod 31 connected to the side plate 41 contracts, and the position of the side plate 41 remains unchanged, so that the toothed plate 37 moves along the direction of the track groove 42 through the limiting rod 43 during the downward movement.

[0047] Furthermore, the pushing component includes a pushing rod 51 fixedly connected to the moving plate 34. The pushing rod 51 contacts the damping rod 23 during its moving stroke. An abutting spring 52 is fixedly connected between the moving block 45 and the limiting frame 44. The pushing rod 51 and the long rod 36 on the toothed plate 37 are fixed on the same moving plate 34. Therefore, when the toothed plate 37 moves, it will drive the pushing rod 51 to move synchronously through the long rod 36 and the moving plate 34. The pushing rod 51 and the toothed plate 37 are respectively arranged on both sides of the damping rod 23. Therefore, when the pushing rod 51 moves, it can push the damping rod 23 to move, so that the first gear 38 on the damping rod 23 always meshes with the toothed plate 37.

[0048] In the embodiment provided by the present invention, the processing component includes a processing rod 61 arranged in the disc 13. Drill bits 62 and long barrel gears 63 are respectively fixedly connected to both ends of the processing rod 61. A groove for the movement of the processing rod 61 is provided on the frustum, and its top end can be connected to an external drive source to drive the processing rod 61 to rotate.

[0049] In the further solution provided by the present invention, the chip removal component includes two side rods 71 arranged on the disc 13. Magnetic cylinders 72 are fixedly connected to both side rods 71. Two second telescopic rods 73 are slidably connected to the disc 13. Scraping frames 74 are fixedly connected to the bottom ends of the two second telescopic rods 73. The two scraping frames 74 are respectively rotatably connected to the corresponding side rods 71. The two side rods 71 are connected to the processing rod 61 through a connecting unit. A groove for the movement of the side rods 71 is provided on the disc 13, so that the side rods 71 can be adjusted synchronously with the processing rod 61. The magnetic cylinders 72 have a certain magnetism, so that they can adsorb the splashing iron chips, and the scraping frames 74 are provided to collect the iron chips attached to the magnetic cylinders 72.

[0050] Specifically, the connecting unit includes connecting bars 81 provided on the processing rod 61 and the two side rods 71. Second gears 82 are fixedly connected to both side rods 71. Both second gears 82 are meshed with the long barrel gear 63. The connecting bar 81 slides horizontally on the top of the disc 13. The processing rod 61 rotates on the connecting bar 81, and the connecting bar 81 is sleeved on the surface of the side rod 71. When the drill bit 62 on the processing rod 61 drills a hole, the magnetic cylinder 72 will move upward due to the support from the top of the workpiece. When the second gear 82 connected to the side rod 71 of the magnetic cylinder 72 is still meshed with the long barrel gear 63 on the processing rod 61, the magnetic cylinder 72 still rotates by itself to adsorb the splashed waste chips. When the processing component is for a larger hole diameter, the magnetic cylinder 72 will directly enter the inner cavity of the workpiece, so as to timely adsorb and process the splashed iron chips.

[0051] In a further solution provided by the present invention, the processing rod 61 is rotatably connected to the top plate 32, and the processing rod 61 rotates on the top plate 32 so that the top plate 32 is maintained at a certain position of the processing rod 61.

[0052] In a further solution provided by the present invention, a driving component is provided on the Y-axis substrate 11. The driving component includes a driving motor 91 fixedly connected to the Y-axis substrate 11; a driving gear 92 is fixedly connected to the output shaft of the driving motor 91. A gear ring cylinder 93 is fixedly connected to the disc 13. The driving gear 92 is meshed with the gear ring cylinder 93. An electric telescopic rod 94 is fixedly connected to the disc 13. The electric telescopic rod 94 is fixedly connected to the connecting bar 81. Both the driving motor 91 and the electric telescopic rod 94 are connected to an external power supply and a control switch. The driving motor 91 drives the driving gear 92 to rotate, meshes with the gear ring cylinder 93 to drive the disc 13 to rotate, so that the processing component makes a circular motion, and the position of the processing component can be adjusted in cooperation with the electric telescopic rod 94 for processing workpieces with different hole diameters.

[0053] Working principle: During operation, place the workpiece on the processing table 1. Adjust the position of the processing component by moving the electric telescopic rod 94. During processing, drive the drill bit 62 on the processing rod 61 to contact the workpiece by lowering the Y-axis substrate 11. Drill a hole by rotating the processing rod 61. While the drill bit 62 drills and moves downward, the side plate 41 contacts the top of the workpiece. At this time, the distance between the top plate 32 connected to the processing rod 61 and the workpiece continuously decreases. The toothed plate 37 in the rectangular cylinder 33 and the push rod 51 connected to the top plate 32 will gradually contact the damping rod 23 and the first gear 38 on the damping rod 23. And when the toothed plate 37 moves downward, it will be affected by the track groove 42 on the side plate 41, so that the positions of the toothed plate 37 and the push rod 51 change, and the push rod 51 will push the damping rod 23 to move synchronously. When the toothed plate 37 moves downward, it will drive the damping rod 23 to rotate, so that the position of the water outlet nozzle 22 continuously changes. Until it reaches a state of a certain hole depth, the water outlet nozzle 22 is perpendicular and gradually fits the processing rod 61 under the action of the toothed plate 37 and the push rod 51, so that the processing position at the deep hole can be flushed and cooled. And the iron chips splashed during flushing and processing will be adsorbed by the magnetic cylinders 72 on both sides. And the second gear 82 on the side rod 71 rotates as the long cylinder gear 63 on the processing rod 61 rotates, and can intermittently transfer the adsorbed iron chips to the scraping frame 74 for collection and treatment.

[0054] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
