Description

Technical Field

[0001] This invention relates to the field of drilling technology, and in particular to a high-precision drilling device for large hole plates. Background Technology

[0002] An orifice plate is a device used for fluid control in pipelines. When there is a large pressure difference across a pipeline, an orifice plate is often added. The principle is that when fluid flows in the pipeline, the local resistance of the orifice plate causes a decrease in fluid pressure and energy loss; this phenomenon is thermodynamically known as throttling. This method is simpler than using a regulating valve, but it must be selected appropriately; otherwise, cavitation can easily occur, affecting the safe operation of the pipeline.

[0003] However, in actual use, the inventors found that when processing large perforated plates, the perforated plates are usually placed horizontally for drilling, and the resulting waste is difficult to clean. Large perforated plates are also heavy and have no gripping points, making them inconvenient to lift and move, which affects the drilling effect of the perforated plates. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a high-precision drilling device specifically designed for large perforated plates. This device can automatically drill holes sequentially on a circular plate, facilitating the lifting and transfer of the plate. The device allows drilling to be performed while the plate is in a vertical position, making it easy to clean up waste materials and resulting in good drilling quality. This solves the technical problems of difficulty in cleaning up waste materials when drilling large perforated plates horizontally, the weight of the plates, and the lack of gripping points, which hinders lifting and transfer and affects the drilling effect.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] Example 1 like Figures 1-3 and Figure 6 As shown, this is a high-precision drilling equipment for large perforated plates. The drilling equipment includes a hoisting mechanism 2, a welding lug mechanism 3, a drilling mechanism 4, and a cutting lug mechanism 5, all mounted on a frame 1. The drilling mechanism 4 includes a drilling assembly 41 mounted on the frame 1, a positioning assembly 42 mounted on the frame 1 for supporting the circular plate 6 in a vertical position, a rotating assembly 43 mounted on the positioning assembly 42 for driving the circular plate to rotate intermittently, and a cleaning assembly 44 mounted on the frame 1 for cleaning debris from the holes in the circular plate. The drilling assembly 41 moves up and down in the vertical direction to drill holes in the surface of the circular plate in sequence. The positioning assembly 42 restricts the circular plate to a vertical state. The rotating assembly 43 drives the circular plate to rotate intermittently to adjust the drilling position. During the rotation of the circular plate, the cleaning assembly 44 cleans the waste debris inside the holes on the circular plate.

[0033] In this embodiment, the two ear plates welded to the circumferential side of the circular plate serve two purposes: first, to facilitate the hoisting and transfer of the circular plate, adjust the circular plate to a vertical position for drilling, and during the drilling process of the circular plate rotating on its own, the protrusions 73 on the ear plates intermittently drive the cleaning component 44 to clean the residual waste in the hole diameter of the circular plate; second, after the circular plate has completed the drilling work, the ear plates can be separated from the circular plate, and the cut-off ear plates can be reused.

[0034] Furthermore, such as Figure 1 and Figures 11-13 As shown, the hoisting mechanism 2 includes: The third slide 21 is mounted on the frame 1, and a third mounting bracket 22 is mounted on the third slide 21. The hanger 23 has a second hydraulic component 24 on the third mounting bracket 22. The hanger 23 is mounted on the output shaft of the second hydraulic component 24. A rotating rod 25 is rotatably mounted on the hanger 23. Two sets of fixing blocks 26 are symmetrically arranged on the rotating rod 25. A second motor 27 for driving the rotating rod 25 is mounted on the hanger 23. L-shaped lifting rods 28, two sets of L-shaped lifting rods 28 are symmetrically hinged at the bottom of the fixed block 26. A third hydraulic component 29 is provided at the bottom of the fixed block 26. A lifting block 291 is provided on the output shaft of the third hydraulic component 29. Two sets of transmission rods 292 are symmetrically hinged on the lifting block 291. One end of each set of transmission rods 292 is respectively hinged to the L-shaped lifting rods 28 and is used to adjust the opening angle of the two sets of L-shaped lifting rods 28.

[0035] It is worth mentioning that both the first positioning groove 33 and the second positioning groove 53 are provided with vertical holes corresponding to the position of the lifting hole 72 of the ear plate. These vertical holes are used for the passage of the two sets of L-shaped lifting rods 28, so that the two sets of L-shaped lifting rods 28 are locked in the lifting hole 72 of the ear plate.

[0036] It should be noted that the third mounting bracket 22 on the third slide 21 is driven by a linear motor of the prior art.

[0037] In this embodiment, the circular plate can be automatically lifted by the hoisting mechanism 2 and the ear plate 7, adjusted to a vertical position, and transferred to a designated position for release. The clamping is firm, the hoisting is stable, and the circular plate is prevented from being bumped and falling.

[0038] In detail, the third slide 21 drives the L-shaped lifting rod 28 on the third mounting bracket 22 to move horizontally to the designated position. The second hydraulic component 24 drives the L-shaped lifting rod 28 on the hanger 23 to descend. Simultaneously, the third hydraulic component 29 drives the lifting block 291 to rise, causing the lifting block 291 to drive the two sets of L-shaped lifting rods 28 closer together via two transmission rods 292, reducing the opening angle of the two sets of L-shaped lifting rods 28. The L-shaped lifting rods 28 descend and pass through the lifting holes 72 of the two sets of ear plates. Then, the third hydraulic component 29 drives the lifting block 291 to descend, causing the lifting block 291 to drive the two sets of L-shaped lifting rods 28 further apart via two transmission rods 292, increasing the opening angle of the two sets of L-shaped lifting rods 28, thereby causing the two sets of L-shaped lifting rods 28 to be locked in the lifting holes 72 of the ear plates. Then, the second hydraulic component 24 drives the L-shaped lifting rod 28 on the hanger 23 to rise, so that the L-shaped lifting rod 28 lifts the circular plate through the two sets of ear plates. At the same time, the second motor 27 drives the rotating rod 25 to rotate the L-shaped lifting rod 28 by 90 degrees, so that the circular plate is in a vertical state. Then, the third slide 21 drives the L-shaped lifting rod 28 on the third mounting bracket 22 to transfer the circular plate to the designated position. The second hydraulic component 24 drives the L-shaped lifting rod 28 on the hanger 23 to fall, so that the vertical circular plate falls onto the arc-shaped support part 428 of the positioning component 42. The opening angle of the two sets of L-shaped lifting rods 28 is reduced again. The third slide 21 drives the L-shaped lifting rod 28 on the third mounting bracket 22 to move horizontally and disengage from the lifting hole 72 of the ear plate, completing the lifting and transfer of the circular plate.

[0039] Furthermore, such as Figure 1 and Figure 14 As shown, the welding lug mechanism 3 includes: A first support plate 31 is disposed on the frame 1. A first placement groove 32 for flatly placing a circular plate is provided on the first support plate 31. A first positioning groove 33 connected to the first placement groove 32 and for flatly placing an ear plate is provided on the first support plate 31. Two sets of first lead screws 34 are rotatably mounted on the first bearing plate 31 and symmetrically located on both sides of the first placement groove 32. The first lead screw 34 is threaded with a first threaded block 35. The first threaded block 35 is provided with a welding gun 36. The first threaded block 35 is provided with a fourth hydraulic component 37 for driving the welding gun 36 to move horizontally. The first bearing plate 31 is provided with a third motor 38 for driving the first lead screw 34. Two sets of welding strip holes 39 are symmetrically opened on the first support plate 31. The welding torch 36 welds the ear plate to the circumferential side of the circular plate along the welding strip holes 39.

[0040] It should be noted that the structure and function of welding torch 36 are existing technologies and will not be described in detail here.

[0041] In this embodiment, the welding ear mechanism 3 facilitates the symmetrical welding of two sets of ear plates onto the circumferential side of the circular plate. The arc surface of the ear plate fits the circumferential side of the circular plate, and the ear plate can be welded tightly onto the circular plate along the arc welding path, resulting in a more secure weld.

[0042] In detail, the circular plate is placed flat in the first placement groove 32 on the first bearing plate 31. The hoisting mechanism 2 places the two sets of ear plates cut off from the ear cutting mechanism 5 flat in the first positioning groove 33. Then, the third motor 38 drives the first threaded block 35 to move horizontally left and right with the welding gun 36 through the first lead screw 34. At the same time, the fourth hydraulic component 37 drives the welding gun 36 to move horizontally back and forth, so that the welding gun 36 follows the circumference of the circular plate as the welding path and welds the arc surface of the ear plate to the circumference of the circular plate.

[0043] Furthermore, such as Figures 2-8 As shown, the positioning component 42 includes: A bracket 421 is mounted on the frame 1, and a rotating shaft 422 is rotatably mounted on the bracket 421. A crossbeam 423 is fixedly mounted on the rotating shaft 422. Ring gear 424, the inner wall of which is disposed at both ends of the crossbeam 423; The two sets of the support frames 425 are symmetrically arranged on the ring gear 424 through the connecting rod 426, and are used to support the ear plate 7 on the circular plate 6. The support frame 425 is provided with an insertion hole 427 that matches the positioning hole 71 of the ear plate 7. An arc-shaped support portion 428 is disposed between the two sets of bearing frames 425 and is used to support the bottom of the vertically positioned circular plate. Insert rod 429, two sets of insert rods 429 are respectively through and slidably disposed on the ring gear 424, and are used to sequentially insert into the insertion hole 427 of the bearing frame 425 and the positioning hole 71 of the ear plate 7. One end of the insert rod 429 is provided with a protruding plate 4291, and a first elastic element is provided between the protruding plate 4291 and the ring gear 424. The insert rod 429 is inserted into the insertion hole 427 of the bearing frame 425 under the elastic force of the first elastic element. Caliper 4292, two sets of first hydraulic components 4293 are symmetrically arranged on the bracket 421, and the two sets of calipers 4292 are respectively arranged on the output shaft of the first hydraulic components 4293, and are used to drive the insertion rod 429 to move horizontally through the protrusion plate 4291; The rotating assembly 43 includes two sets of first motors 431 symmetrically arranged on the bracket 421 and a drive gear 432 arranged on the output shaft of the first motors 431 for driving the ring gear 424.

[0044] In this embodiment, the positioning component 42 and the rotating component 43 work together to support the positioning plate in a vertical position, preventing the plate from tipping over during drilling. This provides a good positioning effect, avoids tilting of the hole diameter on the plate, and improves the drilling and forming effect of the plate. On the other hand, during the drilling process, the plate is prevented from deflecting and sliding, ensuring accurate drilling position and avoiding overlapping of the hole diameters on the plate.

[0045] In detail, the first hydraulic component 4293 drives the convex plate 4291, along with the insertion rod 429, to move horizontally away from the insertion hole 427 of the support frame 425 via the caliper 4292. The hoisting mechanism 2 places the vertically positioned circular plate on the arc-shaped support part 428. At the same time, the two sets of ear plates are located inside the support frame 425. The first hydraulic component 4293 drives the caliper 4292 to move horizontally and reset. Under the elastic force of the first elastic component, the insertion rod 429 is inserted into the insertion hole 427 of the support frame 425 and the positioning hole 71 of the ear plate 7, thereby positioning the circular plate on the arc-shaped support part 428. Then, the first motor 431 drives the ring gear 424 to rotate intermittently by a specified angle via the drive gear 432. The ring gear 424 drives the circular plate to rotate intermittently via the connecting rod 426 and the insertion rod 429, so that the circular plate completes the drilling work in sequence.

[0046] Furthermore, such as Figures 1-2 As shown, the drilling assembly 41 includes: A first slide 411 is mounted on the frame 1, and a first mounting bracket 412 is mounted on the first slide 411. The second slide 413 is disposed on the first mounting bracket 412. The second slide 413 is provided with a second mounting bracket 414. The second mounting bracket 414 is provided with a drilling unit 415, which includes a drive motor and a drill bit of the prior art.

[0047] It is worth mentioning that the first mounting bracket 412 on the first slide 411 and the second mounting bracket 414 on the second slide 413 are driven by linear motors of the prior art.

[0048] In detail, during the intermittent self-rotation of the circular plate, during the time the circular plate is stationary, the first slide 411 drives the drilling unit 415 to move horizontally, and the second slide 413 drives the drilling unit 415 to move up and down, so that the drilling unit 415 drills holes sequentially at designated positions on the circular plate.

[0049] Furthermore, such as Figures 2-10 As shown, the cleaning component 44 includes: A power disk 441 is provided, which is slidably disposed on the rotating shaft 422 through the middle position of the power disk 441 and the end of the rotating shaft 422. A second elastic element 442 is provided between the power disk 441 and the end of the rotating shaft 422. Cleaning rod 443, several sets of cleaning rods 443 are slidably disposed on the power plate 441 and correspond to the drilling positions on the circular plate respectively. A third elastic element is provided between the end of the cleaning rod 443 and the power plate 441. Several sets of clearance holes 444 are provided on the crossbeam 423 for the cleaning rod 443 to pass through. A sealing box 445 is mounted on the bracket 421, and several sets of airbags 446 are evenly distributed on the sealing box 445 along the circumferential direction. The two sets of protrusions 73 are respectively disposed on the two ear plates 7 and are used to sequentially squeeze the airbags 446 during the rotation of the circular plate. Piston cylinder 447 is mounted on the frame 1. The sealing box 445 is connected to the piston cylinder 447 via an air pipe 448. A piston plate 449 is slidably fitted inside the piston cylinder 447. A fourth elastic element 4491 is provided between the piston plate 449 and the end of the piston cylinder 447. The piston plate 449 is provided with a linkage rod 4493. The limiting block 4492 is provided at one end of the linkage rod 4493 that extends to the outside of the piston cylinder 447. The peripheral side of the power plate 441 is provided with a limiting ring 4494. The limiting block 4492 slides on the limiting ring 4494.

[0050] It should be noted that the several sets of cleaning rods 443 on the power plate 441 correspond one-to-one with the positions of the holes to be drilled on the circular plate. During each translation of the power plate 441 carrying the cleaning rods 443 towards the circular plate, the cleaning rods 443 are inserted into the holes to clean the debris at the already drilled positions on the circular plate, and one end of the cleaning rods 443 is pressed against the un-drilled positions on the circular plate, forcing the cleaning rods 443 to slide relative to the power plate 441 and stretching the third elastic element. When the power plate 441 moves away from the circular plate and resets, the cleaning rods 443 are reset under the drive of the third elastic element. This ensures that the debris can be cleaned from the already drilled holes on the circular plate for the next use.

[0051] In this embodiment, the cleaning component 44 can automatically clean the residual debris inside the holes on the circular plate, cleaning the debris inside the holes on the circular plate one by one without any omissions.

[0052] In detail, during the intermittent self-rotation of the circular plate, the power disk 441 rotates synchronously with the circular plate, causing the protrusions 73 on the ear plate 7 to sequentially press the airbags 446 on the sealing box 445. The airbags 446 are deformed by the compression and inflate the piston cylinder 447 through the air pipe 448, causing the piston plate 449 inside the piston cylinder 447 to move. The piston plate 449 drives the limiting block 4492, which in turn moves the power disk 441 towards the circular plate via the linkage rod 4493. At the already drilled positions on the circular plate, the cleaning rod 443 is inserted into the hole to clean the debris. At the un-drilled position, one end of the cleaning rod 443 abuts against the un-drilled position on the circular plate, forcing the cleaning rod 443 to slide relative to the power plate 441 and stretching the third elastic element. After the protrusion 73 on the ear plate 7 disengages from the airbag 446, the airbag 446 returns to its original state. The piston plate 449 is driven by the fourth elastic element 4491 to move and reset, so that the piston plate 449 drives the limit block 4492 through the linkage rod 4493 to move the power plate 441 away from the circular plate and reset. The cleaning rod 443 is reset under the drive of the third elastic element, ready for the next use.

[0053] Example 2 Components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows: Furthermore, such as Figure 1 and Figure 15 As shown, the ear-cutting mechanism 5 includes: The second support plate 51 is disposed on the frame 1. The second support plate 51 has a second placement groove 52 for flatly placing the round plate, and a second positioning groove 53 connected to the second placement groove 52 and for flatly placing the ear plate. The second lead screw 54, two sets of the second lead screw 54 are rotatably mounted on the second bearing plate 51 and symmetrically located on both sides of the second placement groove 52. The second lead screw 54 is threaded with a second threaded block 55. The second threaded block 55 is provided with a cutter 56. The second threaded block 55 is provided with a fifth hydraulic component 57 for driving the cutter 56 to move horizontally. The second bearing plate 51 is provided with a fourth motor 58 for driving the second lead screw 54. Cutting strip holes 59, two sets of cutting strip holes 59 are symmetrically opened on the second support plate 51, and the cutter 56 cuts the ear plate off from the circumferential side of the round plate along the cutting strip holes 59.

[0054] It should be noted that both the first positioning groove 33 and the second positioning groove 53 are provided with vertical holes corresponding to the position of the lifting hole 72 of the ear plate. These vertical holes are used for the passage of the two sets of L-shaped lifting rods 28, so that the two sets of L-shaped lifting rods 28 are locked in the lifting hole 72 of the ear plate.

[0055] In this embodiment, the ear-cutting mechanism 5 can cut off the ear plate along the circumferential side of the circular plate, avoiding ear plate damage and ensuring that the ear plate can be reused.

[0056] In detail, the hoisting mechanism 2 transfers the drilled circular plate to the position of the ear-cutting mechanism 5, so that the circular plate is placed flat in the second placement groove 52 on the second bearing plate 51. At the same time, the two sets of ear plates are respectively located in the second positioning groove 53. Then, the fourth motor 58 drives the second threaded block 55 to move horizontally left and right with the cutter 56 through the second lead screw 54. At the same time, the fifth hydraulic component 57 drives the cutter 56 to move horizontally back and forth, so that the cutter 56 cuts off the ear plates along the circumferential side of the circular plate. The cut ear plates are reused. Finally, the circular plate is taken out for grinding and polishing.

[0057] Work process Step 1, Ear welding process: Two sets of ear plates 7 are symmetrically welded along the sides of the horizontally placed circular plate 6. The ear plates 7 have lifting holes 72 and positioning holes 71. Step 2, hoisting process: hoisting mechanism 2 lifts circular plate 6 upward through ear plate 7, adjusts circular plate 6 to a vertical position, and then transfers circular plate 6 to the position to be drilled; Step 3, drilling process: Positioning component 42 supports the circular plate 6 in a vertical state and limits the circular plate 6 through ear plate 7. Rotation component 43 drives the circular plate 6 to rotate intermittently to adjust the drilling position, thereby drilling holes at designated positions on the circular plate 6 in sequence. During the rotation of the circular plate 6, cleaning component 44 cleans the waste debris in the hole diameter on the circular plate 6. Step four, ear-cutting process: After the round plate is drilled, it is transferred to the cutting position, and the ear plate is cut off from the round plate. The outer side of the round plate is then polished, and the cut-off ear plate is reused.

[0058] In step one, the circular plate and the two sets of ear plates are placed on the same horizontal plane. The arc surfaces of the two sets of ear plates are symmetrically attached to the circumferential side of the circular plate. Solder is filled in the gap between the arc surfaces of the ear plates and the circumferential side of the circular plate to limit the position of the circular plate and the two sets of ear plates.

[0059] In step four, the complete ear plate is cut off from the round plate along the arc surface of the two sets of ear plates to avoid ear plate damage.
