Obviously, the described embodiments are only part of the embodiments of the present invention, not 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.

[0032] See also Figures 1 to 13 In an embodiment of the present invention, a punching device for flange processing includes a three-axis drilling mechanism 2, and a feeding clamping mechanism 3 is provided on one side of the three-axis drilling mechanism 2; The feeding clamping mechanism 3 includes two U-shaped material racks 32, between which a telescopic cylinder 37 is provided, and the cylinder rod of the telescopic cylinder 37 is connected with a T-shaped sleeve rod 39 through a cross-slot coupling 38; the T-shaped sleeve rod 39 is movably connected to the intermediate shaft, and the intermediate shaft is used for the movably connection of the two pressing plates 310; The pressing plate 310 has a U-shaped groove, and both ends of the pressing plate 310 are movably connected to the slider 313 through a rotating shaft; the slider 313 is slidably connected to the slide groove 314 opened on the inner side of the clamping tool 311; The clamping fixture 311 has two stepped grooves for facilitating the clamping of the flange, and the lower end of the clamping fixture 311 is slidably connected to the slide rail 312; two slide rails 312 are provided and fixed on the transition frame plate 321.

[0033] Specifically, the two U-shaped material racks 32 are fixed inside the material storage box 31, and a main bracket 319 is fixed to the bottom of the material storage box 31, and the main bracket 319 is fixed to the chassis 1 by bolts. The upper surface of the main bracket 319 is arranged in an inclined shape, and the material storage box 31 and the U-shaped material rack 32 are cooperatively installed on the inclined surface at the top of the main bracket 319, and the inclination angle is greater than 10 degrees and less than 45 degrees.

[0034] By adopting the above technical solution, when in use, the flange to be processed is first stacked in the two U-shaped material racks 32, and the cylinder rod of the telescopic cylinder 37 is in a retracted state, so that the two pressing plates 310 are retracted in the cavity between the two U-shaped material racks 32, and the clamping tool 311 is fitted with the front end plate 33, and the flange to be processed in the two inclined U-shaped material racks 32 is pushed into the stepped groove inside the clamping tool 311; Then the cylinder rod of the telescopic cylinder 37 is extended, and the clamping tool 311 slides along the slide rail 312 to the clamping table 322 of the V-shaped slide rail 316. At this time, the cylinder rod of the telescopic cylinder 37 continues to extend, and the four sliders 313 installed with the pressing plate 310 slide along the slide groove 314 to the two ends of the clamping tool 311 until the pressing plate 310 presses the flange to be processed, thereby preventing it from falling out during the hole opening process.

[0035] Please see attached Figures 10 to 12 The front end plate 33 is fixed to one end of the material storage box 31 near the material pressing plate 310. A cavity is provided between the front end plate 33 and the U-shaped material rack 32 to accommodate the expansion and contraction of the material blocking plate 36, wherein the material blocking plate 36 is fixed to the cylinder rod of the material blocking cylinder 35; the material blocking cylinder 35 is fixed to the bracket 34, and the bottom of the bracket 34 is fixed to the two sides of the material storage box 31. A rectangular slot is provided in the middle of the front end plate 33 for the two material pressing plates 310 to enter between the two U-shaped material racks 32.

[0036] Specifically, the flanges to be processed have been chamfered before the threaded holes are opened, so there will be a certain gap between the flanges due to the chamfering. By adopting the above technical solution, when a flange enters the clamping fixture 311, the gap between the flange and the next flange is just in the cavity between the front end plate 33 and the U-shaped material rack 32. At this time, the cylinder rod of the material blocking cylinder 35 extends, so that the material blocking plate 36 blocks the two flanges; in this way, after the clamping fixture 311 is removed, the other flange will not fall off.

[0037] Please see attached Figures 5 to 7 , Figures 9 to 12 In this embodiment, the clamping tool 311 is against the clamping table 322 opened in the middle of the V-shaped slide rail 316 when in the processing state; one end of the V-shaped slide rail 316 is fixed with an end stopper 315 by bolts, and a clamping block 317 is slidably connected to the upper surface of the other end of the V-shaped slide rail 316; The clamping block 317 is fixed on the cylinder rod of the clamping cylinder 318; the clamping cylinder 318 is fixed on the fixing seat 320, wherein the fixing seat 320 is fixed to the side of the main bracket 319; the V-shaped slide rail 316 is fixed to the bracket plate 323 by countersunk bolts; the bracket plate 323 and the main bracket 319 are transversely fixed by bolts.

[0038] By adopting the above technical solution, when the clamping tool 311 is against the inner side of the clamping platform 322 opened in the middle of the V-shaped slide rail 316, one side of the clamping tool 311 is matched with the end stop block 315, and then the cylinder rod of the clamping cylinder 318 is extended to push the clamping block 317 to slide along the V-shaped slide rail 316, so that the clamping tool 311 is clamped between the clamping block 317 and the end stop block 315, so that the three-axis drilling mechanism 2 has better stability when drilling holes on the flange.

[0039] Please see attached Figures 1 to 5 In this embodiment, the three-axis drilling mechanism 2 can move along the X, Y, and Z axes and perform drilling operations on the flange; the three-axis drilling mechanism 2 has two drilling drill bits; the three-axis drilling mechanism 2 is installed on the chassis 1.

[0040] Specifically, a workpiece table 5 is provided on one side of the chassis 1, and a discharge mechanism 4 is provided behind the workpiece table 5. The discharge mechanism 4 is used to take out the processed flange.

[0041] By adopting the above technical solution, after the loading and clamping mechanism 3 completes the loading and fixing of the flange, the three-axis drilling mechanism 2 can move along the X, Y, and Z axes to perform hole drilling operations on the flange. After the processing is completed, the processed flange is removed by the unloading mechanism 4 and placed on the workpiece table 5 by itself. This processing process does not require human participation, which greatly improves work efficiency.

[0042] Please see attached Figure 8 In this embodiment, the unloading mechanism 4 includes a linear cylinder 48 fixed on an L-shaped support 41, and a carrier block 44 is fixed to the end of the cylinder rod of the linear cylinder 48; the carrier block 44 is slidably connected to the guide rod 42, and the two ends of the guide rod 42 are respectively fixed to the L-shaped support 41 and the end plate 43; A linear slide 45 is fixed to the outer side of the carrier block 44 , and a lifting frame 46 is mounted on the linear slide 45 ; two suction cups 47 are mounted on the bottom of the lifting frame 46 .

[0043] By adopting the above technical solution, after the flange processing is completed, the cylinder rod of the telescopic cylinder 37 contracts, so that the two pressure plates 310 move closer to the inside and release the pressure on the flange, and then the cylinder rod of the linear cylinder 48 extends, so that the carrier block 44 moves toward the flange along the guide rod 42, and then the linear slide 45 drives the lifting frame 46 to move downward, so that the suction cup 47 fits the outside of the flange, and then the processed flange is sucked in, and the cylinder rod of the linear cylinder 48 contracts, so that the flange moves to the top of the workpiece table 5, and the flange is successfully placed on the workpiece table 5.

[0044] As a further explanation of this embodiment, the suction cup 47 can be a negative pressure suction cup for sucking fiberglass flanges; it can also be an electromagnet flange for sucking metal flanges; or it can be a suction cup with a hook to remove the flange.

[0045] The working principle is: when in use, firstly, the flange to be processed is stacked in two U-shaped material racks 32, and the cylinder rod of the telescopic cylinder 37 is in a retracted state, then the two pressing plates 310 are retracted in the cavity between the two U-shaped material racks 32, the clamping tool 311 is fitted with the front end plate 33, and the flange to be processed in the two inclined U-shaped material racks 32 is pushed into the stepped groove inside the clamping tool 311; Then, the rod of the telescopic cylinder 37 extends, and the clamping tool 311 slides along the slide rail 312 to the clamping table 322 of the V-shaped slide rail 316. At this time, the rod of the telescopic cylinder 37 continues to extend, and the four sliders 313 installed on the pressing plate 310 slide along the slide groove 314 to the two ends of the clamping tool 311 respectively, until the pressing plate 310 presses the flange to be processed, thereby preventing it from falling out during the hole opening process. When the clamping tool 311 is against the inner side of the clamping table 322 opened in the middle of the V-shaped slide rail 316, one side of the clamping tool 311 is matched with the end block 315, and then the cylinder rod of the clamping cylinder 318 is extended to push the clamping block 317 to slide along the V-shaped slide rail 316, so that the clamping tool 311 is clamped between the clamping block 317 and the end block 315, so that the three-axis drilling mechanism 2 has better stability when drilling holes in the flange; the three-axis drilling mechanism 2 moves along the X, Y, and Z axes to perform drilling operations on the flange; After the flange processing is completed, the cylinder rod of the telescopic cylinder 37 contracts, causing the two pressure plates 310 to move closer to the inside and release the pressure on the flange. Then the cylinder rod of the linear cylinder 48 extends, causing the carrier block 44 to move toward the flange along the guide rod 42. Then the linear slide 45 drives the lifting frame 46 to move downward, causing the suction cup 47 to fit the outside of the flange. The processed flange is then sucked in, and the cylinder rod of the linear cylinder 48 contracts, causing the flange to move above the workpiece table 5, and the flange is successfully placed on the workpiece table 5.
