DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment: A knuckle forging inkjet device, such as Figure 1-3As shown, it includes an industrial manipulator 1, a colloidal graphite supply device 2 is fixedly installed on the top of the forearm of the industrial manipulator 1, a colloidal graphite ejection mechanism 3 is arranged on the wrist of the industrial manipulator 1, the output end of the colloidal graphite supply device 2 and the input end of the colloidal graphite ejection mechanism 3 are connected through an ink delivery tube 4, and the colloidal graphite ejection mechanism 3 includes a connector 31 fixedly connected to the movable wrist of the industrial manipulator 1 at one end, a rotating head 32 rotatably connected to the other end of the connector 31 at one end, a rotating component 33 driving the rotating head 32 to rotate relative to the connector 31, a rectangular cylinder 34 vertically fixed to the other end of the rotating head 32, a telescopic slider 35 slidably inserted into the rectangular cylinder 34, a telescopic component 36 driving the telescopic slider 35 to slide relative to the rectangular cylinder 34, and a telescopic slider 35 arranged on the outside of the rectangular cylinder 34. The invention comprises a first end spray port 37, a second spray port 38 respectively arranged on the left and right sides of the telescopic slider 35, an output channel 39 arranged inside the telescopic slider 35 and connecting the first spray port 37 and the two second spray ports 38 at the same time, a blocking component 3a arranged inside the output channel 39 and capable of blocking the first spray port 37 or the two second spray ports 38, and an input pipe port 3b arranged on the front side of the telescopic slider 35 and connecting the output channel 39. The second spray port 38 is located inside the rectangular cylinder 34, and the left and right sides of the rectangular cylinder 34 are provided with square openings 341 for the second spray port 38 to spray colloidal graphite. The input pipe port 3b is close to one end of the telescopic slider 35 located inside the rectangular cylinder 34, and one side of the rectangular cylinder 34 is provided with a long strip gap 342 for the input pipe port 3b to pass through and move. The input pipe port 3b is connected to the ink supply tube 4.

[0026] By adopting the above technical solution, when it is necessary to spray colloidal graphite on the forging die, the industrial robot 1 first extends the colloidal graphite spraying mechanism 3 into the forging equipment, and makes the spraying port 37 of the head of the telescopic slider 35 face the inner wall of the upper forging die or the lower forging die, vertically or on a surface with a certain inclination in the vertical direction; then the colloidal graphite supply device 2 inputs the colloidal graphite to the input port 3b on the front side of the telescopic slider 35 through the ink supply pipe 4, so that the colloidal graphite enters the output channel 39 of the telescopic slider 35 Since the blocking component 3a previously closed the two spray ports 38 on both sides of the telescopic slider 35, the colloidal graphite entering the output channel 39 will be completely sprayed out from the spray port 37, and in conjunction with the up and down swinging of the industrial robot 1, the colloidal graphite can be evenly sprayed on part of the inner wall of the upper forging die or the lower forging die; then, when the vertical or vertically inclined surfaces of the inner walls of the upper forging die and the lower forging die are all sprayed, the blocking component 3a will automatically open the two sides of the telescopic slider 35. The two spray outlets 38 on the side are closed, and the spray outlet 1 37 on the head of the telescopic slider 35 is closed. At the same time, the telescopic assembly 36 drives the telescopic slider 35 to retract into the rectangular cylinder 34, which not only allows the spray outlet 2 38 to be aligned with the square openings on both sides of the rectangular cylinder 34, but also reduces its own volume, thereby enhancing the flexibility of the colloidal graphite spraying mechanism 3 to move between the upper and lower forging dies; finally, the rotating assembly 33 drives the rotating head 32 to rotate relative to the connecting head 31, so that the spray outlet 2 38 on the telescopic slider 35 is aligned with the upper and lower forging dies respectively. On the surface of the inner wall of the forging die that is horizontal or has a certain inclination in the horizontal direction, the colloidal graphite supply device 2 continues to inject colloidal graphite into the output channel 39 of the telescopic slider 35, so that the colloidal graphite is sprayed out from the two nozzles 38 respectively, and in conjunction with the left and right swing of the industrial robot 1, the colloidal graphite can be evenly sprayed on the inner walls of the upper and lower forging dies that are horizontal or have a certain inclination in the horizontal direction. In this way, the colloidal graphite can be sprayed quickly while effectively reducing the repetitive and complex spraying actions of the industrial robot 1.

[0027] Among them, when the closing component 3a blocks the second nozzle 38 and allows the first nozzle 37 to work, the telescopic component 36 will extend the telescopic slider 35 to increase the spraying distance of the first nozzle 37 in the forging die, thereby ensuring that the colloidal graphite can be sprayed to the deepest and innermost area of ​​the forging die; when the closing component 3a blocks the first nozzle 37 and allows the second nozzle 38 to work, the telescopic component 36 will retract the telescopic slider 35 to enhance the flexibility of the second nozzle 38 between the upper and lower forging dies, thereby ensuring that the colloidal graphite can be sprayed to the narrow area in the forging die.

[0028] like Figure 3 , Figure 4As shown, the rotating assembly 33 includes a square groove 331 arranged at the end of the connecting head 31, a transmission shaft 332 horizontally rotatably arranged in the square groove 331, a worm 333 fixedly arranged on the transmission shaft 332, a rotating shaft 334 vertically rotatably arranged in the square groove 331, a worm wheel 335 fixedly arranged on the rotating shaft 334 and meshing with the worm 333, a transmission gear 1 336 fixedly arranged on the transmission shaft 332, a transmission gear 2 337 rotatably arranged on the side wall of the square groove 331 and meshing with the transmission gear 1 336, and a small motor 338 driving the transmission gear 1 336 to rotate. The square groove 331 is located at one end of the connecting head 31 connected to the rotating head 32, one end of the rotating shaft 334 vertically passes through the opening of the square groove 331 and is fixedly connected to the rotating head 32, and the small motor 338 is fixed to the outer wall of the connecting head 31, and the output end passes into the square groove 331 to connect with the transmission gear 2 337.

[0029] By adopting the above-mentioned rotating assembly 33, when it is necessary to drive the rotating head 32 to rotate relative to the connecting head 31, the small motor 338 will drive the transmission gear 2 337 to rotate, so that the transmission gear 2 337 meshes with the transmission transmission gear 1 336, and then the transmission shaft 332 will drive the worm 333 to rotate synchronously under the rotation of the transmission gear 1 336, and make the worm 333 mesh with the transmission worm wheel 335, and finally the worm wheel 335 drives the rotating shaft 334 to rotate, so that the rotating head 32 connected to the rotating shaft 334 rotates. Among them, the transmission of the worm wheel 335 and the worm 333 can not only fully reduce the speed of the small motor 338 and increase the torque of the small motor 338, but also can self-lock and fix the rotating shaft 334 and the rotating head 32 before and after the transmission, so as to ensure that the spray port 1 37 or the spray port 2 38 on the telescopic slider 35 can stably output the sprayed colloidal graphite under the drive of the industrial robot 1.

[0030] like Figure 3 , Figure 6 As shown, the rotating head 32 includes a rotating ring body 321 and a circular cover plate 322, the circular cover plate 322 is screwed to the top of the rotating ring body 321, one end of the rectangular cylinder 34 is fixedly connected to the top of the circular cover plate 322, the upper end of the connecting head 31 is screwed to the fixed ring body 311, the fixed ring body 311 is located in the middle of the rotating ring body 321 and below the circular cover plate 322, and the outer wall of the fixed ring body 311 rotates to contact the inner wall of the rotating ring body 321, the inner wall of the rotating ring body 321 is fixedly provided with a circle of limiting protrusions 321a, the outer wall of the fixed ring body 311 is provided with a circle of limiting grooves 311a for the limiting protrusions 321a to be engaged, the square groove 331 is located in the middle of the fixed ring body 311, and the upper end of the rotating shaft 334 is fixedly connected to the bottom center of the circular cover plate 322.

[0031] By adopting the above-mentioned detachable rotating head 32 structure, not only can the internal parts of the square groove 331 be easily assembled and disassembled for maintenance, but also the rotating head 32 can be stably restricted to rotate on the connecting head 31 in combination with the rotating connection structures such as the fixed ring body 311, the limiting protrusion 321a and the limiting groove 311a, and then the rotation of the rotating head 32 can be accurately and effectively controlled in combination with the rotating component 33.

[0032] like Figure 3 , Figure 4 As shown, the telescopic assembly 36 includes a pair of deep holes 361 opened at the bottom of the telescopic slider 35, a pair of nuts 362 fixedly set inside the deep holes 361, a screw rod 363 threadedly connected to the nut 362 and with the upper end extending into the deep hole 361, a pair of pinions 364 rotatably set at the bottom of the circular cover plate 322, and a plurality of meshing teeth 365 uniformly fixed around the inner wall of the fixed ring body 311 and meshing with the pinion gear 364, and the lower ends of the two screw rods 363 are fixedly provided with connecting shafts 366 that rotate and pass through the circular cover plate 322, and the lower ends of the two connecting shafts 366 are respectively fixedly connected to the two pinions 364.

[0033] By adopting the telescopic assembly 36, when the rotating head 32 rotates relative to the connecting head 31, the two pinions 364 will orbit around the center of the rotating shaft 334. Since the pinion 364 meshes with the meshing teeth 365 on the inner wall of the fixed ring body 311, the pinion 364 will mesh with the meshing teeth 365 on the inner wall of the fixed ring body 311 under the above-mentioned orbiting movement and generate self-rotation. Since the pinion 364 and the screw rod 363 are connected by the connecting shaft 366, the screw rod 363 will rotate under the self-rotation of the pinion 364. It will rotate relative to the nut 362 and gradually extend into or out of the deep hole 361 at the bottom of the telescopic slider 35, and the telescopic slider 35 will telescope and slide relatively in the rectangular cylinder 34. In this way, not only the rotation of the rotating head 32 and the telescopic movement of the telescopic slider 35 can be carried out simultaneously, but also the telescopic movement of the telescopic slider 35 is converted from the rotation of the rotating head 32. Therefore, there is no need to supply it with a separate energy source for the telescopic movement, thereby fully reducing the production cost of the entire colloidal graphite ejection mechanism 3.

[0034] like Figure 3 , Figure 5As shown, the blocking assembly 3a includes a pair of hinge shafts 3a1 which are parallel to each other and are horizontally rotatably arranged inside the channel, a pair of blocking plates 3a2 which are fixedly connected to the hinge shafts 3a1 at one end and are flip-movable inside the channel, a pair of movable shafts 3a3 which are respectively fixedly connected to the two blocking plates 3a2 and are parallel to the hinge shafts 3a1, a pair of arc-shaped long strip holes 3a4 which are opened on one side of the telescopic slider 35 and allow one end of the two movable shafts 3a3 to extend out of the channel, and a horizontally arranged inner wall of the rectangular cylinder 34 and allow one end of the two movable shafts 3a3 to extend into the slide. The two blocking plates 3a2 are respectively located at the connecting parts of the channel and the two spray outlets 38, and the flipping directions are opposite. When the two blocking plates 3a2 are vertically parallel to each other, they can respectively block the connecting ports of the channel and the two spray outlets 38. When the two blocking plates 3a2 are horizontally flush, the ends of the two blocking plates 3a2 respectively away from the hinge shaft 3a1 are close to each other, and jointly block the connecting port of the channel and the spray outlet 37. The two arc-shaped long strip holes 3a4 are symmetrical to each other and are coaxial with the two hinge shafts 3a1 respectively.

[0035] By adopting the above-mentioned blocking component 3a, when the telescopic slider 35 extends out of the rectangular cylinder 34, since the movable shaft 3a3 slides through the two symmetrical arc-shaped long holes 3a4 on one side of the telescopic slider 35, and the other end extends into the long groove 3a5 on the inner wall of the rectangular cylinder 34, during the telescopic slider 35 extending and retracting relative to the rectangular cylinder 34, the movable shaft 3a3 will slide along the arc-shaped long holes 3a4 and the long groove 3a5 at the same time. Since the two arc-shaped long holes 3a4 are coaxial with the two hinge shafts 3a1 respectively, the blocking plate 3a3 is in the process of sliding along the arc-shaped long holes 3a4. a2 will be driven by the movable shaft 3a3, with the hinge shaft 3a1 as the rotation center, and will turn over in the direction of blocking the channel and the connecting opening of the first spray outlet 38. At the same time, the other blocking plate 3a2 will be driven by its movable shaft 3a3, and will turn over in the direction of blocking the channel and the connecting opening of the other spray outlet 38. Finally, when the movable shaft 3a3 slides to the lower end of the arc-shaped long hole 3a4, the two blocking plates 3a2 will be vertically parallel to each other, not only blocking the two spray outlets 38 respectively, but also at this time, the telescopic slider 35 reaches the maximum extension, and the square opening 341 and the spray outlet 38 are completely staggered up and down.

[0036] When the telescopic slider 35 is retracted into the rectangular cylinder 34, the two movable shafts 3a3 will slide in the opposite direction along the arc-shaped long hole 3a4 again, and respectively drive the respectively connected blocking plates 3a2 to flip in the direction of jointly blocking the connecting opening of the channel and the nozzle 1 37. Finally, after the movable shaft 3a3 slides to the upper end of the arc-shaped long hole 3a4, the two blocking plates 3a2 will be horizontally flush, not only jointly blocking the connecting opening of the channel and the nozzle 1 37, but also at this time the telescopic slider 35 is retracted to the original position in the rectangular cylinder, and the square opening 341 and the nozzle 2 38 are aligned with each other. Among them, the structures such as the movable shaft 3a3, the arc-shaped long hole 3a4 and the long slide groove 3a5 in the blocking component 3a not only realize the telescopic movement of the telescopic slider 35 and the flipping movement of the blocking plate 3a2 at the same time, but also the flipping movement of the blocking plate 3a2 is converted from the telescopic movement of the telescopic slider 35. Therefore, there is no need to supply it with a separate energy source for the flipping movement, thereby fully reducing the production cost of the entire colloidal graphite ejection mechanism 3.
