The machining table 1 and the Y-axis substrate 11 are both existing vertical machining equipment. In addition, the machining table 1 is also provided with a substrate that drives the workpiece to move in the X and Z axes. Its structure is the basic part of the vertical machining center. The connection method between its substrates is also the existing technology, which will not be described in detail here. A liquid storage cylinder 12 is fixedly connected to the Y-axis substrate 11. The liquid storage cylinder 12 stores coolant. The outside of the liquid storage cylinder 12 is rotatably connected to a disc 13, and a machining component is provided on the disc 13; it also includes a water spray component and a chip removal component, which is provided On the disc 13; during processing, the position of the water spray component is adaptively adjusted through the trigger mechanism, and water is sprayed to cool and remove dust at the apertures of different depths at the processing location, and the chip removal component is used to absorb and collect the splashing debris as the processing component moves. When the processing component processes the workpiece on the processing table 1, the top of the workpiece will contact the trigger mechanism, and as the processing component goes deeper and deeper into the interior of the workpiece, the trigger mechanism is affected by the top of the workpiece and triggers the water spray component to adaptively adjust its position, which is convenient for cooling the apertures of different depths, and the chip removal component can absorb the splashing iron chips to avoid the accumulation of iron chips and affect the normal operation of its processing components.

[0044] In an embodiment further provided by the present invention, a water spray assembly includes a water pipe 21 connected to a liquid storage cylinder 12, the water pipe 21 is connected to a water outlet 22, both sides of the water outlet 22 are fixedly connected to damping rods 23, the water outlet 22 is arranged on one side of the processing assembly, and a water pump is arranged in the liquid storage cylinder 12, and the liquid inside the liquid storage cylinder 12 can be introduced into the water outlet 22 through the water pipe 21 and sprayed out to cool down and remove dust from the processing area.

[0045] In the embodiment further provided by the present invention, the trigger mechanism includes a plurality of first telescopic rods 31 slidably connected to the disc 13, and the plurality of first telescopic rods 31 are fixedly connected to the same top plate 32; there are two rectangular tubes 33 sliding horizontally on the top plate 32, and a moving plate 34 is slidably connected in the two rectangular tubes 33, and a support spring 35 is fixedly connected between each moving plate 34 and the corresponding rectangular tube 33, and a long rod 36 is fixedly connected to the two moving plates 34, and a toothed plate 37 is fixedly connected to the two long rods 36, and a first gear 38 is fixedly connected to the two damping rods 23, and the two toothed plates 37 are respectively meshed with the corresponding first gears 38 during the movement of the two toothed plates 37; the two telescopic rods are both provided with a guiding component, and the two moving plates 34 are also provided with a pushing component for driving the corresponding resistance rods to move, by setting the first telescopic rod 31 and the top plate 32, which are used to fix and support the rectangular tube 33, and the two rectangular tubes 33 are respectively arranged at both sides of the processing component, when the toothed plate 37 moves with the first gear 38 When the tooth plate 37 contacts 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 that the angle of the water outlet nozzle 22 can be adjusted to spray water at processing locations of different depths, until the tooth plate 37 engages the first gear 38 and cooperates with the damping rod 23 to drive the water outlet nozzle 22 to be vertical to the top of the workpiece. At this time, the tooth plate 37 will separate 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 remains in a state of separation from the tooth plate 37, until the bottom of the tooth plate 37 contacts the top of the workpiece, the tooth plate 37 no longer moves downward, and the rectangular cylinder 33 is abutted and squeezes the support spring 35 to gradually move downward. When the processing assembly drills a hole to a certain depth, the water outlet nozzle 22 will drive the water outlet nozzle 22 to move toward the processing assembly side under the cooperation of the pushing assembly and the guiding assembly when it is close to vertical rotation, so that the water outlet nozzle 22 can move to the top of the hole to spray water, wherein the elastic force of the support spring 35 is greater than the resistance between the tooth plate 37 and the first gear 38.

When the processing assembly contacts the top of the workpiece, the side plate 41 arranged on the first telescopic rod 31 will contact the top of the workpiece. As the Y-axis substrate 11 drives the processing assembly to move downward continuously, the first telescopic rod 31 connected to the side plate 41 is contracted, and the position of the side plate 41 is kept unchanged, so that the tooth plate 37 moves in the direction of the track groove 42 through the limit rod 43 when moving downward.

[0047] Furthermore, the pushing assembly includes a pushing rod 51 fixedly connected to the moving plate 34, and the pushing rod 51 contacts the damping rod 23 during its movement. An abutment spring 52 is fixedly connected between the moving block 45 and the limit frame 44.

The pushing rod 51 and the tooth plate 37 are respectively arranged on both sides of the damping rod 23, so when the pushing rod 51 moves, the damping rod 23 can be pushed to move, so that the first gear 38 on the damping rod 23 always remains engaged with the tooth plate 37.

[0048] In the embodiment provided by the present invention, the processing assembly includes a processing rod 61 arranged in the disc 13, and the two ends of the processing rod 61 are respectively fixedly connected with a drill bit 62 and a long cylinder gear 63.

A groove for the movement of the side rod 71 is provided on the disc 13, so that the side rod 71 can be adjusted synchronously with the processing rod 61, and the magnetic tube 72 has a certain magnetism, so that it can absorb the flying iron chips, and the scraper frame 74 is provided to collect the iron chips attached to the magnetic tube 72.

[0050] Specifically, the connecting unit includes a connecting strip 81 arranged on the processing rod 61 and the two side rods 71, and the two side rods 71 ​​are fixedly connected with a second gear 82, and the two second gears 82 are meshed with the long cylinder gear 63. The connecting strip 81 slides horizontally on the top of the disc 13, and the processing rod 61 rotates on the connecting strip 81, and the connecting strip 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 tube 72 will receive the support of the top of the workpiece and move upward. When the second gear 82 connected to the magnetic tube 72 and the side rod 71 will also mesh with the long cylinder gear 63 on the processing rod 61, so that the magnetic tube 72 can still rotate and absorb the waste chips splashed up. When the processing component has a larger aperture, the magnetic tube 72 will directly enter the inner cavity of the workpiece, so that the splashed iron chips can be absorbed and processed in time.

[0051] In a solution further 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 the solution further provided by the present invention, a driving assembly is provided on the Y-axis substrate 11, and the driving assembly 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, and a gear ring cylinder 93 is fixedly connected to the disc 13, the driving gear 92 is meshed with the gear ring cylinder 93, and an electric telescopic rod 94 is fixedly connected to the disc 13, and the electric telescopic rod 94 is fixedly connected to the connecting bar 81. The driving motor 91 and the electric telescopic rod 94 are both connected to an external power supply and a control switch, the driving motor 91 drives the driving gear 92 to rotate, and the meshing gear ring cylinder 93 drives the disc 13 to rotate, so that the processing assembly performs a circular motion, and the position of the processing assembly can be adjusted in conjunction with the electric telescopic rod 94, so as to process workpieces with different apertures.

[0053] Working principle: When working, the workpiece is placed on the processing table 1, and the position of the processing assembly is adjusted by moving the electric telescopic rod 94. During processing, the drill bit 62 on the processing rod 61 is driven to contact the workpiece by moving the Y-axis base plate 11 downward, and a hole is drilled by rotating the processing rod 61. When the drill bit 62 moves downward while drilling the hole, 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 is continuously reduced, and the tooth plate 37 in the rectangular tube 33 connected to the top plate 32 and the push rod 51 will gradually contact the damping rod 23 and the first gear 38 on the damping rod 23, and the tooth plate 37 will be affected by the track groove 42 on the side plate 41 when moving downward, 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, and the downward movement of the toothed plate 37 will drive the damping rod 23 to rotate, so that the position of the water outlet 22 is constantly changed. When a certain hole depth is reached, the water outlet 22 is vertically 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 filings splashed during flushing and processing will be absorbed by the magnetic cylinder 72 on both sides, and the second gear 82 on the side rod 71 rotates with the rotation of the long cylinder gear 63 on the processing rod 61, so that the absorbed iron filings can be intermittently transferred to the scraper frame 74 for collection and processing.
