[0002] A numerical control machine tool is a high-precision and high-efficiency automated machine tool widely used in modern manufacturing. As one of the key components of a numerical control machine tool, during long-term use, the cutting tool will gradually become dull due to friction and cutting with the workpiece material, and it is necessary to periodically passivate the cutting tool to restore its sharpness and performance.

[0003] The passivation device for cutting tools of a numerical control machine tool described in the prior art includes a bottom plate. A passivation box is fixedly connected to the upper part of the bottom plate. An aeration mechanism is arranged at the bottom end inside the passivation box.

[0011] Specifically, in this technical solution, electric sliding rails are screw-mounted on the inner walls on both sides of the push-pull groove. Sliding grooves are formed on both side walls of the push-pull plate and are slidably connected to the electric sliding rails.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0020] Next, the embodiments of the present invention will be described according to the overall structure of the present invention. Embodiment

[0021] Before the passivation treatment starts, the push-pull plate 304 is located in the push-pull groove 301, the anti-detachment component 6 abuts against the L-shaped suspension rod 3041, the drying component 7 is retracted in the storage groove 101, and all the electrical components in the device are controlled by an external controller to ensure operation safety; It should be noted that an air supply pipe is provided at the inner bottom of the passivation tank 2, and the air supply pipe is connected to an external air source and is used to provide a uniform air flow during the passivation process to ensure the passivation effect.

[0022] Please refer to Figures 1-5 As shown, a passivation device for a cutting tool of a numerical control machine tool includes a base 1, a passivation tank 2 installed above the base 1, a lifting plate 3 above the passivation tank 2, a push-pull groove 301 is opened below the lifting plate 3, electric slide rails 303 are screw-mounted on both inner walls of the push-pull groove 301, sliding grooves are opened on both side walls of the push-pull plate 304 and are slidably connected to the electric slide rails 303, a plurality of L-shaped suspension rods 3041 are installed on the lower surface of the push-pull plate 304, and an adjustment mechanism 4 for preventing the cutting tool from falling off and drying, a storage groove 101 is opened at the bottom of the base 1, a support block 103 is screw-fixed on the upper surface of the base 1 on one side of the passivation tank 2, a second installation groove 1031 is opened on the lower surface of the support block 103, a first installation groove 102 matching the second installation groove 1031 is opened on the upper surface of the base 1 at the position of the support block 103, hydraulic cylinders 104 are screw-mounted on both sides of the upper surface of the support block 103, lifting rods 1041 are screw-mounted on the telescopic ends of the two hydraulic cylinders 104, sliding grooves 302 communicating with the push-pull groove 301 are symmetrically opened at the top of the lifting plate 3, and L-shaped connecting rods 1042 are symmetrically welded on the upper surface of the lifting plate 3, and the two L-shaped connecting rods 1042 are both screw-mounted on the outer wall of the lifting rod 1041; The adjustment mechanism 4 is composed of a transmission component 5, an anti-detachment component 6, a drying component 7 and two L-shaped pull rods 8. The transmission component 5 is arranged on the push-pull plate 304, the anti-detachment component 6 is arranged between the two L-shaped connecting rods 1042 and the actuator is used to contact the end of the L-shaped suspension rod 3041, and the transmission component 5 is used to control the movement of the anti-detachment component 6 following the movement of the push-pull plate 304. The drying component 7 is arranged in the storage groove 101 and is connected to the push-pull plate 304 through the L-shaped pull rod 8.

[0023] When passivating the cutting tool of a numerically controlled machine tool, the controller is started, and the electric slide rail 303 drives the push-pull plate 304 to move out along the push-pull groove 301. Under the action of the L-shaped pull rod 8, the drying component 7 will extend out of the storage groove 101 following the movement of the push-pull plate 304. At this time, the staff hangs the cutting tool on the L-shaped hanging rod 3041. The push-pull plate 304 resets and retracts into the push-pull groove 301. The anti-dropping component 6 operates under the action of the transmission component 5 to abut against the L-shaped hanging rod 3041 to ensure the stability of the cutting tool. Then, the lifting plate 3 slowly descends under the drive of the hydraulic cylinder 104, and the chemical solution in the passivation tank 2 gradually submerges the cutting tool. The passivating agent in the chemical solution acts evenly on the surface of the tool, effectively removing the burrs on the edge and improving the durability of the tool; After passivation is completed, the lifting plate 3 rises. When the push-pull plate 304 moves the cutting tool out of the push-pull groove 301, the anti-dropping component 6 moves in the reverse direction under the action of the transmission component 5 to cancel the abutment with the L-shaped hanging rod 3041. At this time, the drying component 7 is located below the cutting tool. The drying component 7 is started, and hot air evenly blows on the surface of the tool to quickly remove the residual chemical solution. Finally, the passivated and dried cutting tool is removed from the L-shaped hanging rod 3041 to complete the passivation process; Thus, through the coordinated action of the anti-dropping component 6 and the transmission component 5, it is ensured that the cutting tool always maintains a stable position and posture during the passivation process, avoiding the risk of dropping, enabling the surface of the cutting tool to uniformly contact the passivation liquid, and improving the consistency and reliability of the passivation effect.

[0024] Please refer to Figures 5-8 As shown, the anti-dropping component 6 includes two rotating shafts 606. Meshing gears 607 are fixedly sleeved on both rotating shafts 606. The two rotating shafts 606 are connected by a lead screw 601. Three L-shaped moving rods 602 are sleeved on the lead screw 601. Five baffles 603 are evenly arranged below the lifting plate 3. One side of each of the five baffles 603 matches the end of the L-shaped moving rod 602. Connecting plates 6021 are fixed at the ends of the five baffles 603. The outer walls of the bottoms of the three L-shaped moving rods 602 are fixedly connected to the connecting plates 6021. Support plates 605 are fixedly arranged below the outer walls of the two L-shaped connecting rods 1042. The ends of the two rotating shafts 606 away from the lead screw 601 are rotatably connected to the support plates 605. Slide rods 6041 pass through the three L-shaped moving rods 602. Side plates 604 are fixed at both ends of the slide rods 6041. Both side plates 604 are fixedly connected to the outer wall of the lifting plate 3; The transmission assembly 5 includes two fixed blocks 501, the two fixed blocks 501 are welded to the push-pull plate 304, the top ends of the two fixed blocks 501 are each screw-mounted with a horizontal plate 502, the upper surfaces of the two horizontal plates 502 are each provided with an inner track tooth 5021, the two meshing gears 607 are each matched with the inner track tooth 5021, the side walls of the two fixed blocks 501 are each in contact with the groove wall of the sliding groove 302 and are slidably connected, the lower surfaces of the two horizontal plates 502 are each in contact with the upper surface of the lifting plate 3 through embedded balls, a cross bar 5022 is fixed between the two horizontal plates 502, and a stop block 305 is screw-fixed to one end of the upper surface of the lifting plate 3 away from the lead screw 601.

[0025] When the push-pull plate 304 moves, the fixed block 501 drives the horizontal plate 502 to move, the inner track tooth 5021 on the horizontal plate 502 drives the meshing gear 607 to rotate, and then drives the lead screw 601 to rotate through the rotating shaft 606. The helical movement of the lead screw 601 pushes the three L-shaped moving rods 602 to move along the sliding rod 6041. The three L-shaped moving rods 602 drive a plurality of baffle plates 603 to move synchronously through the connecting plate 6021, so that the contact ends with the L-shaped suspension rod 3041 are separated, facilitating hanging the cutting tool on the L-shaped suspension rod 3041. Among them, the arrangement of the cross bar 5022 and the stop block 305 can limit the moving-out position of the push-pull plate 304 to prevent it from disengaging from the push-pull groove 301; After the cutting tool is mounted, the push-pull plate 304 drives the cutting tool to slowly reset. As the horizontal plate 502 moves, the inner track tooth 5021 gradually meshes with the meshing gear 607, driving the lead screw 601 to rotate in the reverse direction. The three L-shaped moving rods 602 retract along the sliding rod 6041, and the connecting plate 6021 drives the baffle plate 603 to fit the L-shaped suspension rod 3041 again, ensuring that the cutting tool is stably suspended. The whole device returns to the initial state, thereby realizing the convenient mounting and safe fixing of the cutting tool, improving the work efficiency, ensuring the operation safety, and improving the overall compactness and space utilization rate of the equipment through the compact layout.

[0026] Please refer to Figure 3 、 Figure 4 and Figure 9As shown in the figure, the drying component 7 includes a moving plate 701 disposed in the storage groove 101. A plurality of spray pipes 702 are uniformly installed inside the moving plate 701. A plurality of nozzles 7021 passing through the moving plate 701 are provided on each of the plurality of spray pipes 702. A plurality of L-shaped branch pipes 704 are uniformly provided in the first installation groove 102. Heating coils 7041 are sleeved on each of the plurality of L-shaped branch pipes 704. The L ends of the plurality of L-shaped branch pipes 704 all pass through the first installation groove 102 and are connected to a telescopic pipe 703. Each of the plurality of telescopic pipes 703 is connected to the spray pipe 702. A horizontal air supply pipe 705 is provided at the top of the second installation groove 1031. The top ends of the plurality of L-shaped branch pipes 704 are all located in the second installation groove 1031 and are connected to the air supply pipe 705. A blower 706 is installed on the upper surface of the support block 103 by screws. The output pipe of the blower 706 is connected to the air supply pipe 705. The height and length of the moving plate 701 are both smaller than those of the storage groove 101. The lower surface of the moving plate 701 contacts the ground through several embedded balls. Two L-shaped pull rods 8 are symmetrically arranged on both sides of the moving plate 701. The outer walls of the bottom ends of the two L-shaped pull rods 8 are fixedly screwed to the end face of the moving plate 701, and the outer walls of the L ends of the two L-shaped pull rods 8 are fixedly screwed to the lower surface of the push-pull plate 304.

[0027] The connection method between two of the L-shaped pull rods 8 and the moving plate 701 can also be replaced by the magnetic adsorption of an electromagnet, that is, the electromagnet is embedded in the moving plate 701. After the passivation is completed, through the magnetic adsorption of the electromagnet, the moving plate 701 is connected to the push-pull plate 304 to achieve rapid separation and adsorption, improving the operation flexibility.

[0028] After the passivation treatment is completed, the lifting plate 3 rises to take the cutting tool out of the passivation liquid. At this time, the push-pull plate 304 moves driven by the electric slide rail 303. The moving plate 701 is pulled out of the storage groove 101 through the L-shaped pull rod 8, and the telescopic pipe 703 is stretched, so that the nozzle 7021 is aligned with the cutting tool. Then the blower 706 and the heating coil 7041 start to work. The blower 706 conveys air through the air supply pipe 705, the L-shaped branch pipe 704, the telescopic pipe 703 and the spray pipe 702 to the nozzle 7021. The nozzle 7021 uniformly sprays the air flow onto the cutting tool, and the heating coil 7041 heats the L-shaped branch pipe 704 to make the blown air have a certain temperature, accelerating the evaporation of the residual liquid on the surface of the cutting tool, and then being able to quickly remove the residual liquid on the surface of the cutting tool, shortening the entire processing cycle and enabling it to be put into the next stage of use faster; And it can be retracted into the storage groove 101 during non-use and the passivation process, making the occupied space of the entire device smaller, the structure more compact, reducing the wear and damage caused by accidental collision, corrosion, etc., and extending the service life.

[0029] The working principle of the present invention is: When passivating the cutting tool of a numerically controlled machine tool, the controller is started, and the electric slide rail 303 drives the push-pull plate 304 to move out along the push-pull groove 301. When the push-pull plate 304 moves, it drives the horizontal plate 502 to move through the fixed block 501. The inner teeth 5021 on the horizontal plate 502 drive the meshing gear 607 to rotate, and then drive the lead screw 601 to rotate through the rotating shaft 606. The helical movement of the lead screw 601 pushes the three L-shaped moving rods 602 to move along the slide rod 6041. The three L-shaped moving rods 602 drive a plurality of baffles 603 to move synchronously through the connecting plate 6021, so that the contact end with the L-shaped suspension rod 3041 is separated, facilitating hanging the cutting tool on the L-shaped suspension rod 3041. And the drying assembly 7 will also extend out of the storage groove 101 following the movement of the push-pull plate 304 under the action of the L-shaped pull rod 8. After the cutting tool is mounted, the push-pull plate 304 drives the cutting tool to slowly reset. As the horizontal plate 502 moves, the inner teeth 5021 gradually mesh with the meshing gear 607, driving the lead screw 601 to rotate in the reverse direction. The three L-shaped moving rods 602 retract along the slide rod 6041, and the connecting plate 6021 drives the baffle 603 to fit the L-shaped suspension rod 3041 again to ensure that the cutting tool is stably hung. Then the lifting plate 3 slowly descends under the drive of the hydraulic cylinder 104, and the chemical solution in the passivation tank 2 gradually submerges the cutting tool. The passivator in the chemical solution acts uniformly on the tool surface, effectively removing the burrs at the cutting edge. After passivation is completed, the lifting plate 3 rises to take the cutting tool out of the passivation liquid. At this time, the push-pull plate 304 moves driven by the electric slide rail 303, pulls the moving plate 701 out of the storage groove 101 through the L-shaped pull rod 8, and stretches the telescopic tube 703 to align the nozzle 7021 with the cutting tool. Then the blower 706 and the heating coil 7041 start to work. The blower 706 conveys air through the air supply pipe 705, L-shaped branch pipe 704, telescopic tube 703 and spray pipe 702 to the nozzle 7021. The nozzle 7021 uniformly sprays the heated air flow onto the cutting tool to quickly remove the residual chemical solution. Finally, the passivated and dried cutting tool is removed from the L-shaped suspension rod 3041 to complete the passivation process.
