[0002] Machine tool processing refers to the manufacturing process of using machine tools (mechanical equipment) to perform cutting, grinding, milling, drilling, tapping and other processing on workpieces to achieve the required size, shape and surface quality. It is widely used in many fields such as metal processing, plastic processing, and composite material processing.

[0003] When existing machine tools perform multiple drilling operations on workpieces, the drilling tools are switched manually, and the machine tool needs to stop processing before the tool can be changed, which reduces work efficiency and requires manual supervision, increasing labor costs. At the same time, due to inconsistent tool specifications, the tool is cooled by only one nozzle during the overall cooling process, which can easily cause uneven coolant spraying and cooling dead corners, making it difficult to cool the local temperature of the tool, and even causing the tool to break at this location. Summary of the Invention

The movable seat can move on the base to prevent the two meeting pneumatic clamps from colliding, while keeping the pneumatic clamps on the central axis of the support frame, so that the tool clamped by the clamping block can be clamped.

[0026] The present invention provides a drilling method for a tool drilling device for machine tool processing, comprising the following steps: S1: When it is necessary to switch the drilling tool, the annular housing is pushed down by pushing the hydraulic cylinder, so that the switching motor drives the switching frame to rotate, thereby driving the unused tool upward. The rotating component is started, and the base on the conveying guide rail is driven to move. The base drives the rollers on the moving seat to move in the pushing groove. The two groups of moving seats move in opposite directions, one group is close to the tool groove, and the other group is close to the switching frame. The rollers move along the track of the pushing groove. The rollers pull the moving seat to move on the base, driving the pneumatic clamps to move outward, so that the two groups of pneumatic clamps can reset after meeting and passing each other.

After the lifting rod rises again, it drives the clamped pneumatic clamp to rise, and the rotating component drives the clamped pneumatic clamp to move toward the switching frame. After encountering the deflection rack, it deflects, so that the pneumatic clamp faces the switching frame, and after placing the clamped tool in the clamping shell, the clamping of the tool is completed by the relative movement of the clamping block, while the facing tool is not affected in processing the workpiece; S4: After the coolant is sucked into the storage chamber by the water pump, it is transported into the cooling nozzle through the hose.

[0028] 2. By setting up a clamping device, it is possible to better and stably clamp tools of various diameters. The clamping block in the clamping shell moves relative or oppositely on the limit guide rail, thereby completing the clamping and releasing of the tool. The rotation of the clamping screw can drive the push frame to rise and fall, thereby driving the push connecting rod to deflect, pulling the clamping block to move, and automatically completing the clamping of the tool. The teeth on the clamping block increase the friction between the tool and the clamping block, which is convenient for stable clamping of the tool. By plugging the toothed disc lock groove and the driven friction disc into the driven friction disc, the driven friction disc can be limited to prevent the driven friction disc from rotating and affecting the clamping of the tool, thereby stably clamping the tool and preventing the tool from shaking slightly and affecting the drilling accuracy.

[0029] 3. By setting up a cooling device, a variety of tools can be fully cooled. The inclination angle of the cooling nozzle can be changed according to the diameter of the tool, so that the sprayed coolant can fit the surface of the tool to complete the cooling work. The cooling nozzles distributed in a ring array can fully flush the surface of the tool and increase the cooling effect. In order to achieve uniform adjustment of the cooling nozzles, the motor is adjusted to drive a driven bevel gear fixed to it to rotate, which drives the rotation of the driving bevel gear disk, thereby driving the rotation of the remaining driven bevel gears. The worm can drive the worm wheel to rotate, thereby changing the angle of the cooling nozzle, solving the technical problem that the existing machine tools are prone to uneven coolant spraying and easy to cause tool breakage.

After the clamping screw 66 drives the pushing frame 67 to rise, it drives the pushing connecting rod 65 to deflect, and pushes the clamping block 63 on the connecting pushing limit guide rail 62 to move outward, thereby releasing the clamping of the tool; S3: After the lifting rod 42 rack on the support sleeve 4 is engaged with the lifting gear 44, the motor is started to drive the lifting gear 44 to rotate, thereby driving the lifting rod 42 to rise, driving the released clamped tool to rise and leave the clamping shell 61. At the same time, the gears on the other set of support sleeves 4 encounter the deflected rack 41 and drive the support sleeve 4 to rotate. After the support sleeve 4 turns, the pneumatic clamp 43 faces the tool slot 24, and the rack on the lifting rod 42 is engaged with the lifting gear 44, driving the pneumatic clamp After the claw 43 descends, it clamps the tool in the tool slot 24 on the rotating component 3. After the lifting rod 42 rises again, it drives the clamping pneumatic claw 43 to rise. The rotating component 3 drives the clamping pneumatic claw 43 to move toward the switching frame 51. After encountering the deflection rack 41, it deflects, so that the pneumatic claw 43 faces the switching frame 51. After placing the clamped tool in the clamping housing 61, the clamping block 63 moves relative to the tool to complete the clamping of the tool, while not affecting the facing tool to process the workpiece; S4: After the coolant is sucked into the storage chamber 8 by the water pump, it is transported into the cooling nozzle 88 through the hose. When the angle of the cooling nozzle 88 needs to be adjusted, the adjustment motor 89 is started to drive a driven bevel gear 85 to rotate, and the driven bevel gear 85 drives the driving bevel gear 84 to rotate, and the driving bevel gear 84 drives the remaining driven bevel gears 85 to rotate, thereby driving the worm 86 on the driven bevel gear 85 to rotate, thereby driving the worm wheel 87 to rotate and drive the cooling nozzle 88 to deflect, so that the angle of the cooling nozzle 88 toward the tool can be adjusted.
