Description

Technical Field

[0001] The invention relates to the technical field of drilling devices, in particular to a valve drilling and boring processing device. Background Art

[0002] The valve drilling and boring processing device is a highly specialized machine tool, mainly used in the valve manufacturing and maintenance industry for precise drilling and boring operations. This device integrates advanced technology and precision engineering design, and through a high-precision stepper motor and screw drive system, the valve drilling and boring processing device can achieve high-precision drilling and boring operations to meet the strict requirements of valve manufacturing and maintenance. It can efficiently and accurately complete valve processing tasks, ensuring processing quality while improving production efficiency.

[0003] Bolt holes are holes on the flange surface of the valve specially designed for installing bolts. They are evenly distributed around the flange according to specific standards and layouts. Usually an even number of them ensures the symmetry and stability of the connection. Due to the differences in the size of the valve and the number and position of the bolt holes, the processing of the bolt holes requires drilling equipment to process them one by one, which leads to a long production time for the valve and is not conducive to mass production.

[0004] During the drilling and boring process of the valve drilling and boring processing device, it is necessary to spray cooling oil on the drill bit and boring cutter to prevent the drill bit and boring cutter from being damaged due to high temperature caused by long-term friction with the valve. Traditional spraying devices usually add oil spray pipes on the outside of the drill bit and boring cutter to cool them, but it is often impossible to spray cooling oil to the contact position between the drill bit and boring cutter and the valve, making it difficult to achieve accurate and effective cooling.

[0017] (III) Beneficial effects

[0018] The valve drilling and boring processing device provided by the present invention has the following beneficial effects:

[0019] 1. The present invention uses a drilling assembly and installs the same number of drilling cutters according to the number of bolt holes of the valve. The motor drives the active gear to rotate, and the drilling cutter rotates to drill holes for the valve, so that multiple drilling cutters drill bolt holes for the valve at the same time, achieving the effect of processing multiple bolt holes at one time. By controlling the extension or contraction of the electric hydraulic rod, the multiple drilling cutters are moved away from or close to the installation tube as the center, thereby achieving the effect of adjusting the drilling positions of the multiple drilling cutters, so that the drilling positions of the drilling cutters are adapted to the bolt hole positions of valves of different sizes, so that the device can process valve bolt holes of different sizes, thereby increasing the processing range of the device, and cooperating with multiple drilling cutters to process all the bolt holes of the valve at one time, thereby shortening the processing time of the valve.

[0020] 2. The present invention uses a cooling component. The oil pump extracts the cooling oil from the recovery pool and sprays it from the spray tank through the vertical slot to the turning position of the drilling tool and the valve, directly cooling the drill bit and the turning position of the drilling tool. No matter how the drilling tool moves, the cooling oil sprayed from the spray tank can accurately cool the drilling tool and the turning position. When the mounting block is installed in the mounting cylinder, the cooling oil is sprayed through the spray head, and the cooling oil cools the cutting position and the tool head of the boring rack, achieving the effect of accurately spraying the cooling oil to the drill bit and the tool head of the boring rack. The traditional spray device sprays The oil pipe cools down the drilling tool and the boring frame, but the movement of the drilling tool and the boring frame makes it impossible for the oil injection pipe to accurately spray to the drilling tool and the boring frame. The device allows the cooling oil to be sprayed through the injection groove inside the drilling tool and the nozzle inside the boring frame, so that the cooling oil can avoid inaccurate injection caused by the movement of the drilling tool and the boring frame. At the same time, the cooling oil can be stably and continuously sprayed during the rotation of the drilling tool and the boring frame to cool the drilling tool, the boring frame's tool head and the cut part, thereby avoiding overheating and causing damage to the drilling tool, the boring frame's tool head and the cut part.

[0021] 3. In the present invention, by using the protection component, the splashing cooling oil and metal chips will be blocked by the inner wall of the protection shell. Since the cooling oil is sprayed onto the inner wall of the protection shell and the inner wall of the protection shell has a large area, the surface area of ​​the cooling oil increases when it is spread out, thereby accelerating the heat dissipation of the cooling oil. The rotation of the boring frame drives the oil scraper rod to rotate, and the oil scraper rod scrapes the cooling oil and metal chips adhered to the inner wall of the protective shell, causing them to fall from the lower oil port, thereby achieving the effects of accelerating the heat dissipation of the cooling oil and accelerating the circulation of the cooling oil, and avoiding the situation in which the cooling oil is directly recovered and difficult to dissipate heat, resulting in excessively high temperature of the cooling oil. The cooling oil is spread on the inner wall of the protection shell to increase the heat dissipation area and is scraped and recovered by the oil scraper rod after heat dissipation, thereby ensuring that the cooling oil can obtain sufficient heat dissipation and actively scraping and recovering the cooling oil to accelerate the circulation of the cooling oil.

[0050] The following is the entire working process and working principle of the above embodiment: the user removes the mounting block 215 installed inside the motor 24, so that the mounting block 215, the boring frame 216 and the oil scraper rod 56 are removed, the connecting ring 313 is separated from the outer sliding tube 314, and the sealing plate inside the connecting ring 313 is closed, so that the connecting ring 313 is sealed to prevent the cooling oil from leaking from the connection between the connecting ring 313 and the outer sliding tube 314. The user installs the same number of drilling cutters 212 inside the mounting seat 211 according to the number of bolt holes of the valve. Since the mounting seat 211 is provided with twelve, the device is suitable for processing valves including twelve bolt holes. The user turns on the motor 24, and the output shaft of the motor 24 drives the driving gear 26 fixedly connected to it to rotate Since the driving gear 26 is meshed with the driven gear 28, the driving gear 26 drives the driven gear 28 to rotate, the driven gear 28 drives the connecting rod 29 to rotate through the latch, the connecting rod 29 drives the connecting cylinder 210 to rotate, the connecting cylinder 210 drives the mounting seat 211 to rotate through the latch, the mounting seat 211 drives the drilling cutter 212 to rotate, the user controls the lateral support rod 21 to move toward the valve direction, so that the drilling cutter 212 moves toward the valve direction, the drilling cutter 212 rotates to drill holes for the valve, so that multiple drilling cutters 212 drill bolt holes for the valve at the same time, achieving the effect of processing multiple bolt holes at one time, the user controls the electric hydraulic rod 22 to extend, the electric hydraulic rod 22 pushes the moving circle 23 to move toward the driving gear 26, the moving circle 2 3 drives the adjusting rod 213 connected to the rotation thereof to rotate clockwise with the connection between the adjusting rod 213 and the moving ring 23 as the rotation center, the adjusting rod 213 drives the adjusting frame 214 connected to the rotation thereof to move away from the driving gear 26, the adjusting frame 214 drives the mounting seat 211 connected to the rotation thereof to move away from the mounting cylinder 27, the mounting seat 211 drives the connecting cylinder 210 to deflect through the latch, the connecting cylinder 210 drives the connecting rod 29 connected to the sliding connection thereof to deflect, the connecting rod 29 extends out from the inside of the connecting cylinder 210, the mounting seat 211 drives the drilling cutter 212 to move away from the mounting cylinder 27, so that the multiple drilling cutters 212 move away from each other with the mounting cylinder 27 as the center, so that the multiple drilling cutters 212 can adapt to the valve with the bolt holes farther apart. The user controls the electric hydraulic rod 22 to retract, and the electric hydraulic rod 22 pulls the moving ring 23 to move away from the driving gear 26. The moving ring 23 pulls the adjusting rod 213 to make the adjusting frame 214 move toward the mounting cylinder 27. The adjusting frame 214 drives the mounting seat 211 to make the drilling cutter 212 move toward the mounting cylinder 27. Therefore, the multiple drilling cutters 212 are close to each other with the mounting cylinder 27 as the center, so that the multiple drilling cutters 212 can adapt to the valve with a closer distance between the bolt holes. By controlling the extension or contraction of the electric hydraulic rod 22 to make the multiple drilling cutters 212 move away from or close to the mounting cylinder 27 as the center, the effect of adjusting the drilling positions of the multiple drilling cutters 212 is achieved, so that the drilling positions of the drilling cutters 212 can adapt to the bolt hole positions of valves of different sizes.The device can process valve bolt holes of different sizes, thereby increasing the processing range of the device and cooperating with multiple drilling cutters 212 to process all bolt holes of the valve at one time, thereby shortening the processing time of the valve.

[0051] Further, the user removes all the drilling cutters 212, and reinstalls the mounting block 215 inside the mounting tube 27, so that the mounting block 215, the boring frame 216 and the scraper rod 56 are installed on the device, the connecting ring 313 and the outer sliding tube 314 are installed together, the sealing plate inside the connecting ring 313 is opened to connect the connecting ring 313 and the outer sliding tube 314, and the scraper rod 56 is close to the inner wall of the protective shell 51. The user loosens the screws on the outside of the mounting block 215, moves the boring frame 216, and makes the distance from the cutting head of the boring frame 216 away from the mounting block 215 to the center of the mounting block 215 be the same as the inner hole diameter of the valve, and the user turns on the motor 24, and the output shaft of the motor 24 drives the driving gear 2 6 rotates, the driving gear 26 drives the mounting cylinder 27 to rotate, the mounting cylinder 27 drives the mounting block 215 mounted therein to rotate, the mounting block 215 drives the boring rack 216 to rotate, the boring rack 216 rotates to bore holes inside the valve, when the device stops running, the user loosens the screws on the outside of the mounting block 215, moves the boring rack 216, so that the distance from the tool head of the boring rack 216 close to the mounting block 215 to the center of the mounting block 215 is the same as the diameter of the outside of the valve, so that the boring rack 216 can turn the outside of the flange surface of the valve when rotating, so as to achieve the effect of boring holes inside the valve and turning the outside of the flange surface of the valve, and the two positions of the valve are processed by adjusting the boring rack 216.

[0052] Furthermore, the user turns on the oil pump 31, and the oil pump 31 extracts the cooling oil in the recovery pool 32 through the oil extraction hose 33, and the cooling oil is transported to the inside of the oil guide tube 35 through the output pipe 34, and the cooling oil in the oil guide tube 35 enters the inside of the oil guide ring 38 through the outer tube 36 and the inner tube 37. Since the oil guide ring 38 is connected with the vertical groove 311, the cooling oil in the oil guide ring 38 can also enter the vertical groove 311 during the rotation of the vertical groove 311 and the injection groove 312, and the cooling oil is ejected from the injection groove 312 through the vertical groove 311, and sprayed to the turning position of the drilling tool 212 and the valve, so as to directly cool the tool head and the turning position of the drilling tool 212. No matter how the drilling tool 212 moves, the cooling oil is The spray from the spray slot 312 can accurately cool the drilling tool 212 and the turning position. When the drilling tool 212 is removed and not in use, the blocking spring 39 extends and pushes the blocking block 310 to seal the oil guide ring 38 to prevent the oil guide ring 38 from leaking cooling oil when the drilling tool 212 is removed and not in use. When the mounting seat 211 is driven by the adjustment frame 214, the mounting seat 211 drives the oil guide ring 38 rotatably connected thereto to move, and the oil guide ring 38 drives the inner tube 37 fixedly connected thereto to move, and the inner tube 37 slides inside the outer tube 36. Therefore, when the mounting seat 211 moves, the outer tube 36 is connected to the inner tube 37, so that after the mounting seat 211 moves to adjust the position of the drilling tool 212, the outer tube 36 can still supply cooling oil to the inner tube 37.

[0053] When the mounting block 215 is mounted inside the mounting cylinder 27, the cooling oil inside the oil guide tube 35 passes through the connecting ring 313 and enters the outer sliding tube 314 through the connecting ring 313, and the cooling oil inside the outer sliding tube 314 enters the inner delivery pipe 315 through the outer sliding pipe 314, and the cooling oil is sprayed from the nozzle 316 through the inner delivery pipe 315, and the cooling oil cools the cutting part and the tool head of the boring rack 216. Since the connecting ring 313 is rotatably connected to the inner delivery pipe 315, the oil guide tube 35 can also supply cooling oil to the connecting ring 313 during the valve processing of the boring rack 216, so that the nozzle 316 can continuously spray cooling oil, thereby achieving the effect of accurately spraying cooling oil to the drilling tool 212 and the tool head of the boring rack 216. The device cools down the drilling tool 212 and the boring rack 216 through the oil spray pipe, but due to the movement of the drilling tool 212 and the boring rack 216, the oil spray pipe cannot accurately spray to the drilling tool 212 and the boring rack 216. The device makes the cooling oil spray out through the spray groove 312 inside the drilling tool 212 and the nozzle 316 inside the boring rack 216, so that the cooling oil can avoid the situation that the movement of the drilling tool 212 and the boring rack 216 causes inaccurate spraying. At the same time, during the rotation of the drilling tool 212 and the boring rack 216, the cooling oil can also be stably and continuously sprayed to cool down the tool head and the cut part of the drilling tool 212 and the boring rack 216, so as to avoid the situation that the tool head and the cut part of the drilling tool 212 and the boring rack 216 are damaged due to overheating;

[0054] Since there are two nozzles 316, when one of the nozzles 316 is not in use, the user pushes the moving block 43 in the direction of the blocking rod 41 to deflect the driven rod 42, and the driven rod 42 drives the blocking rod 41 to move downward. The blocking rod 41 enters the interior of the nozzle 316 to close the nozzle 316, thereby avoiding oil leakage when not in use.

[0055] Furthermore, the splashing cooling oil and metal chips will be blocked by the inner wall of the protective shell 51, and the cooling oil will flow downward along the inner wall of the protective shell 51 from the lower oil port 52 to the top of the recovery pool 32, and will be re-extracted by the oil pump 31 after being filtered through the filter screen inside the recovery pool 32. Since the cooling oil is sprayed onto the inner wall of the protective shell 51 and the inner wall area of ​​the protective shell 51 is large, the surface area of ​​the cooling oil is increased when it is spread, which accelerates the heat dissipation of the cooling oil. Fig.11 The oil scraper rod 56 is in a compressed state, so the spring 54 close to the moving rod 55 will push the moving rod 55 to make the oil scraper rod 56 close to the inner wall of the protective shell 51. When the boring frame 216 rotates, the boring frame 216 drives the fixed cylinder 53 to rotate the moving rod 55, and the moving rod 55 drives the oil scraper rod 56 to rotate. The oil scraper rod 56 scrapes the cooling oil and metal chips adhered to the inner wall of the protective shell 51, causing them to fall from the lower oil port 52, thereby achieving the effect of accelerating the heat dissipation of the cooling oil and accelerating the circulation of the cooling oil, and avoiding the cooling oil being directly In the case where the cooling oil temperature is too high due to difficulty in heat dissipation, the cooling oil is spread on the inner wall of the protective shell 51 to increase the heat dissipation area and is scraped and recovered by the oil scraper rod 56 after heat dissipation. This not only ensures that the cooling oil can be fully cooled, but also actively scrapes and recovers the cooling oil to speed up the circulation of the cooling oil. When the boring frame 216 is moved and adjusted, the spring 54 will stretch or contract to drive the moving rod 55 to make the oil scraper rod 56 close to the inner wall of the protective shell 51, so that the oil scraper rod 56 can always be close to the inner wall of the protective shell 51.
