Description

TECHNICAL FIELD

[0002] The valve drilling and boring hole machining device is a highly specialized machine tool, mainly used in the valve manufacturing and maintenance industry for precise drilling and boring operations. Through the integration of advanced technology and precise engineering design, the valve drilling and boring hole machining device can realize high-precision drilling and boring operations through high-precision stepping motors and screw rod transmission systems, meeting the strict requirements of valve manufacturing and maintenance, and efficiently and accurately completing the valve machining task while ensuring the machining quality and improving the production efficiency.

[0003] Bolt holes are holes designed specifically for installing bolts on the flange surface of a valve. They are evenly distributed around the flange according to specific standards and layouts, usually in even numbers to ensure symmetry and stability of the connection. Due to 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 one by one, which results in a long valve production time, which is not conducive to mass production.

[0004] During the drilling and boring process of the valve drilling and boring hole machining device, cooling oil needs to be sprayed to the drill bit and boring cutter to prevent damage caused by high temperature due to long-term friction with the valve. Traditional spraying devices usually increase oil injection pipes on the outside of the drill bit and boring cutter for cooling, but often cannot spray cooling oil to the contact position of the drill bit and boring cutter with the valve, making it difficult to achieve accurate and effective cooling.

[0051] Further, the user will be removed from all drilling cutter 212, the user will be installed inside the cylinder 27 reinstallation installation block 215, so that the installation block 215, with the boring frame 216 and oil scraping rod 56 are installed on the device, the connection ring 313 and the outer slide tube 314 are installed together, open the seal plate inside the connection ring 313 so that the connection ring 313 and the outer slide tube 314 communication, oil scraping rod 56 close to the inner wall of the protective shell 51, the user loosens the screw outside the installation block 215, move boring frame 216, so that the boring frame 216 away from the installation block 215 cutter head to the center of the installation block 215 distance and the diameter of the valve hole is the same, the user opens the motor 24, the output shaft of the motor 24 drive gear 26 rotation, drive gear 26 drive installation cylinder 27 rotation, installation cylinder 27 drive installation inside the installation block 215 rotation, installation block 215 drive boring frame 216 rotation, boring frame 216 rotation can be boring inside the valve, when the device stops running, the user loosens the screw outside the installation block 215, move boring frame 216, so that the boring frame 216 close to the installation block 215 cutter head to the center of the installation block 215 distance and the diameter of the valve outside is the same, so that the boring frame 216 in rotation can be flange face outside the valve turning, reached for the valve boring and turning the flange face outside the valve effect, by adjusting the boring frame 216 complete two position processing of the valve.

[0052] Further, the user opens the oil pump 31, the oil pump 31 extracts the cooling oil in the recovery tank 32 through the oil extraction hose 33, the cooling oil is transported into the oil guide pipe 35 through the output pipe 34, the cooling oil in the oil guide pipe 35 enters the oil guide ring 38 through the outer pipe 36 and the inner pipe 37, since the oil guide ring 38 is communicated 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 jet groove 312, the cooling oil is sprayed from the jet groove 312 through the vertical groove 311, and sprayed to the turning position of the drill bit 212 and the valve, directly cooling the drill bit 212 and the turning position, no matter how the drill bit 212 moves, the cooling oil sprayed from the jet groove 312 can accurately cool the drill bit 212 and the turning position, when the drill bit 212 is removed and not used, the blocking spring 39 extends to push the blocking block 310 to seal the oil guide ring 38, avoiding the oil guide ring 38 from leaking cooling oil when the drill bit 212 is removed and not used, when the mounting seat 211 is driven by the adjusting frame 214, the mounting seat 211 drives the oil guide ring 38 connected with it to move, the oil guide ring 38 drives the inner pipe 37 fixedly connected with it to move, the inner pipe 37 slides in the outer pipe 36, so that the outer pipe 36 is communicated with the inner pipe 37 when the mounting seat 211 moves, so that the outer pipe 36 can still supply cooling oil to the inner pipe 37 after the mounting seat 211 moves to adjust the position of the drill bit 212;

[0053] When the mounting block 215 is installed in the mounting cylinder 27, the cooling oil in the oil guide pipe 35 enters the outer sliding pipe 314 through the connecting ring 313, the cooling oil in the outer sliding pipe 314 enters the inner conveying pipe 315 through the outer sliding pipe 314, the cooling oil is sprayed from the nozzle 316 through the inner conveying pipe 315, and the cooling oil cools the cutting part and the drill bit of the boring frame 216, since the connecting ring 313 is rotationally connected with the inner conveying pipe 315, the oil guide pipe 35 can also supply cooling oil to the connecting ring 313 during the machining of the valve by the boring frame 216, so that the nozzle 316 can continuously spray cooling oil, achieving the effect of accurately spraying cooling oil to the drill bit 212 and the drill bit of the boring frame 216, the traditional spraying device cools the drill bit 212 and the boring frame 216 through the oil spraying pipe, but since the drill bit 212 and the boring frame 216 move, the oil spraying pipe cannot accurately spray to the drill bit 212 and the boring frame 216, the device makes the cooling oil sprayed from the jet groove 312 in the drill bit 212 and the nozzle 316 in the boring frame 216, so that the cooling oil can avoid the inaccuracy caused by the movement of the drill bit 212 and the boring frame 216, and the cooling oil can also stably and continuously spray during the rotation of the drill bit 212 and the boring frame 216 to cool the drill bit 212, the drill bit of the boring frame 216 and the cut part, avoiding the damage of the drill bit 212, the drill bit of the boring frame 216 and the cut part caused by 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 toward 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 and closes 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 and flow from the lower oil port 52 to the top of the recovery pool 32, and will be filtered by the filter screen inside the recovery pool 32 and then be re-extracted by the oil pump 31 for reuse. 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 out, which accelerates the heat dissipation of the cooling oil. Figure 11 The oil scraping rod 56 is in a compressed state, so the spring 54 close to the movable rod 55 will push the movable rod 56 to close 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 movable rod 55, and the movable rod 55 drives the oil scraping rod 56 to rotate. The oil scraping rod 56 scrapes the cooling oil and metal chips adhered to the inner wall of the protective shell 51 and makes them 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, 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 ensures that the cooling oil can be fully dissipated and 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.
