Description

Technical Field

[0001] This invention relates to the field of valve processing technology, specifically to a cutting machine tool for valve processing. Background Technology

[0002] Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. During valve manufacturing, the valve body needs to be connected to the pipeline. Before connecting the valve body to the pipeline, the connection point between the valve body and the pipeline needs to be cut to ensure a tight connection between the valve body and the pipeline.

[0003] In the prior art, when cutting valve bodies, cutting oil is usually used to cool and lubricate the cutting parts of the valve body. Therefore, a certain amount of lubricating oil usually adheres to the valve body after cutting. The lubricating oil adhering to the valve body will form oil sludge, which will affect the subsequent processing of the valve body and cause a large amount of lubricating oil waste, which is not conducive to the recovery of lubricating oil. Furthermore, during the cutting process, the valve body needs to be clamped and fixed by a clamping structure. The clamping structure in the prior art is usually as shown in the authorized patent application number CN201921328438.7, which uses a clamping plate to limit the inner or outer wall of the valve body. This clamping structure only has the function of fixing the valve body and cannot prevent lubricating oil from splashing onto the unprocessed parts of the valve body. Moreover, lubricating oil dripping onto the clamping plate will cause lubricating oil splashing, which is not conducive to the recovery of lubricating oil. Based on this, this application proposes a cutting machine tool for valve body processing. Summary of the Invention

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] This invention provides a cutting machine tool for valve processing, including a machine tool body 1. The machining cavity of the machine tool body 1 is provided with a clamping structure and a cleaning structure. The clamping structure is used to clamp the valve body to be cut, and when in use, the clamping structure can cover the unprocessed parts of the valve body to be processed, exposing the processed parts of the valve body, thereby reducing the amount of cutting fluid adhering to the valve body.

[0031] The clamping structure includes a push tube 8 movably connected to the machine tool body 1, a hydraulic telescopic rod 14 fixedly connected to the machine tool body 1, and a blower 12 fixedly connected to the machine tool body 1. One end of the push tube 8 is fixedly connected to the cutting base 3, and one end of the push tube 8 extends into the inner cavity of the cutting base 3. The other end of the hydraulic telescopic rod 14 is fixedly connected to the end of the push tube 8 away from the cutting base 3. The air outlet of the blower 12 is fixedly connected to the end of the push tube 8 away from the cutting base 3 through an air inlet pipe 13. The extension and retraction of the hydraulic telescopic rod 14 changes the movement of the push tube 8, which in turn moves the cutting base 3. Under the action of the hydraulic telescopic rod 14, the cutting base 3 can move away from or closer to the cavity door of the machining chamber of the machine tool, facilitating the removal and placement of valve bodies. The blower 12 blows outside air into the inner cavity of the cutting base 3.

[0032] A lower clamping block 4 is movably connected to the top of the inner cavity of the cutting base 3. A rotating shaft 25 is fixedly connected to the middle of the bottom of the lower clamping block 4. The rotating shaft 25 is movably connected to the middle of the top of the inner cavity of the cutting base 3. The lower clamping block 4 is movably connected to the top of the inner cavity of the cutting base 3 via the rotating shaft 25. A gear ring is fixedly connected to the outer ring at the bottom of the rotating shaft 25. A rotary motor 23 is fixedly connected to the bottom of the inner cavity of the cutting base 3. A gear 24 is fixedly connected to the end of the output shaft of the rotary motor 23 via a reducer. The gear 24 meshes with the gear ring. Through the setting of the rotary motor 23, the rotation of the rotary motor 23 can drive the gear 24 fixedly connected to it to rotate. The gear 24, through the gear ring meshing with it, can drive the rotating shaft 25 to rotate. The rotating shaft 25 drives the lower clamping block 4 fixedly connected to it to rotate. Thus, when the cutting machine tool is in use, the position of the valve body to be cut on the cutting base 3 can be changed, which facilitates the cutting machine tool to process the valve body and facilitates the cleaning structure to clean the valve body.

[0033] An electromagnet 27 is fixed to one side of the bottom of the lower clamping block 4. The clamping structure also includes a lifting hydraulic rod 2 fixed to the top of the machining cavity of the machine tool body 1. An electromagnet 6 is fixedly connected to the bottom of the lifting hydraulic rod 2. An upper clamping block 5 is snapped into the top of the lower clamping block 4. The cavity formed when the lower clamping block 4 and the upper clamping block 5 are snapped into each other is adapted to the valve body. Both the lower clamping block 4 and the upper clamping block 5 include a mesh shell 31 adapted to the valve body. The mesh shell 31 is made of ferromagnetic material. As described above, when electromagnet 27 is energized, it magnetically attracts the upper clamping block 5, improving the reliability of the connection between the lower clamping block 4 and the upper clamping block 5. When electromagnet 6 is energized, it magnetically attracts the upper clamping block 5, and under the action of the lifting hydraulic rod 2, the upper clamping block 5 and the lower clamping block 4 can be separated, facilitating the removal and placement of the valve body. In some embodiments of this application, the mesh outer shell 31 is made of iron.

[0034] A locking block 30 is fixed to one side of the top of the lower clamping block 4. The bottom of the upper clamping block 5 is provided with a slot 34 that matches the locking block 30. Both the middle of the locking block 30 and the middle of the top of the slot 34 are provided with through holes. An air bladder 33 is fixed to the bottom of the inner cavity of the mesh shell 31. The air bladder 33 and the mesh shell 31 are filled with oil-absorbing cotton 32. The oil-absorbing cotton 32 can absorb the cutting fluid used for lubrication during the valve body processing. In use, this clamping structure can reduce the splashing degree when the cutting fluid comes into contact with the upper or lower clamping block, which facilitates the recovery of cutting oil. The connecting pipe 26 is Y-shaped. The air inlet of the connecting pipe 26 is located in the inner cavity of the cutting base 3. One air outlet of the connecting pipe 26 extends into the inner cavity of the air bladder 33 in the lower clamping block 4, and the other air outlet of the connecting pipe 26 extends into the through hole located in the middle of the locking block 30.

[0035] As described above, the two air bladders 33 in the clamping structure are connected by a connecting pipe 26. When the blower 12 is working, the air in the inner cavity of the cutting base 3 can enter the two air bladders 33 in the clamping structure along the connecting pipe 26, causing the air bladders 33 to expand. When the air bladders 33 expand, they can squeeze the oil-absorbing cotton 32, and the cutting oil absorbed in the oil-absorbing cotton 32 can be squeezed out, which facilitates the recovery of the cutting oil.

[0036] There are at least two cleaning structures used to clean the inner cavity of the valve body and the parts exposed outside the clamping structure. The cleaning structures include a wiping mechanism and a shielding cover that protects the wiping mechanism. The wiping mechanism includes a hydraulic telescopic rod 20 fixedly connected to the machine tool body 1. A limiting plate 16 is fixedly connected to the other end of the hydraulic telescopic rod 20. The limiting plate 16 is located inside the inner cavity of the machine tool body 1. An oil suction ring 17 is fixedly connected to the end of the limiting plate 16 away from the hydraulic telescopic rod 20. The inner diameter of the oil suction ring 17 is adapted to the outer diameter of the valve body end. Under the action of the hydraulic telescopic rod 20, the oil suction ring 17 can suck away the lubricating oil adhering to the outer surface of the valve body end. Furthermore, the width of the oil suction ring 17 is equal to the distance between the valve body end and the upper clamping block 5, facilitating the cleaning of cutting oil from the valve body by the oil suction ring 17.

[0037] A connecting rod 19, a vacuum pump 35 fixedly connected to the machine tool body 1, and a plugging rod adapted to the inner cavity of the valve body are fixedly connected to the middle of the end of the limiting plate 16 away from the hydraulic telescopic rod 20. The other end of the connecting rod 19 is fixedly connected to a vacuum suction cup 18. The air inlet of the vacuum pump 35 is connected to the vacuum suction cup 18 through a vacuum tube 15. Under the action of the vacuum pump 35, the vacuum suction cup 18 can make negative pressure connection with the object it contacts. The plugging rod includes a central rod 21 adapted to the vacuum suction cup 18 and an oil suction rod 22 fixed outside the central rod 21. When the vacuum suction cup 18 is negatively connected to the central rod 21, the hydraulic telescopic rod 20 can drive the plugging rod to move. During the cutting process of the valve body, the plugging rod can block the inner cavity of the valve body to prevent the cutting fluid from entering the inner cavity of the valve body.

[0038] In this application, both the vacuum tube 15 and the air inlet tube 13 are retractable pipes. In some embodiments of this application, the vacuum tube 15 and the air inlet tube 13 are both made of corrugated pipe, and the inflatable bladder 33 can be made of rubber.

[0039] The shielding cover includes an upper shielding plate 9 fixedly connected to the inner wall of the machine tool body 1 and a rotating plate 10 that contacts the end of the upper shielding plate 9 near the cutting base 3. During the processing of the valve body, the shielding cover composed of the upper shielding plate 9 and the rotating plate 10 can shield the wiping structure, reducing the amount of splashed cutting fluid falling onto the wiping structure. In addition, the distance between the vacuum suction cup and the rotating plate 10 is not less than the length of the plugging rod, which facilitates the oil removal operation of the plugging rod.

[0040] The rotating plate 10 is movably connected to the machine tool body 1. A rotating motor 7 is fixed on the machine tool body 1. The output shaft end of the rotating motor 7 is fixedly connected to the rotating plate 10 through a reducer. With the setting of the rotating motor 7, the rotation of the rotating motor 7 can drive the rotating plate 10 fixedly connected to it to rotate. When it is necessary to clean the residual cutting fluid on the valve body, the rotating plate 10 is separated from the upper baffle plate 9 under the action of the rotating motor 7, which facilitates the movement of the wiping structure.

[0041] The rotating plate 10 has a squeezing hole in the middle that is adapted to the plugging rod, and a cross valve 11 is fixed on the outer side of the inner cavity of the squeezing hole. By setting the cross valve 11, the cross valve 11 can block the squeezing hole and prevent the cutting fluid from contacting the wiping structure through the squeezing hole. When the plugging rod passes through the squeezing hole, the squeezing hole can squeeze the plugging rod, so that the cutting oil adsorbed on the oil suction rod 22 is squeezed out.

[0042] The materials of the oil-absorbing rod 22, oil-absorbing ring 17 and oil-absorbing cotton 32 mentioned above are all capable of absorbing cutting fluid. Under external pressure, the cutting fluid absorbed in the oil-absorbing rod 22, oil-absorbing ring 17 or oil-absorbing cotton 32 can be squeezed out. In some embodiments of this application, the materials of the oil-absorbing ring 17 and oil-absorbing cotton 32 are all oil-absorbing felt.

[0043] All electrical components involved in this application are prior art. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies can be connected by wires. According to the actual situation, a suitable controller can be selected to meet the control requirements. For specific connections and control sequences, please refer to the description below. The electrical connection between each electrical component is completed in the order of operation. The detailed connection methods are well known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0044] In some embodiments of this application, the model of the machine tool body 1 is CY-VTC3250, and the models of both electromagnet 6 and electromagnet 27 are BJ-DH-50.

[0045] In summary: When using this valve machining machine tool, the valve body 29 to be machined is fixed by the clamping structure as shown in the attached instruction manual. Figure 5 As shown, the plugging rod is located inside the valve body 29, and the electromagnet 27 is energized. During the valve body manufacturing process, the wiping structure is shielded by the shield, as shown in the instruction manual. Figure 2 and attached Figure 3As shown, after the valve body is processed, the blower 12 starts working first. The operation of the blower 12 causes outside air to be blown into the inner cavity of the cutting base 3. The air in the inner cavity of the cutting base 3 enters the air bladder 33 along the connecting pipe 26. The air bladder 33 expands in volume and squeezes the oil-absorbing cotton 32 in contact with it. The cutting fluid in the oil-absorbing cotton 32 is squeezed out. When the blower 12 stops working, the air bladder 33 returns to its original position under the action of the rebound force of the air bladder 33, and the gas in the air bladder 33 is squeezed out. During the cleaning process, the rotating motor 7 drives the rotating plate 10 to rotate. When the rotating plate 10 moves to the side of the upper baffle 9, the hydraulic telescopic rod 20 extends. The hydraulic telescopic rod 20 drives the oil suction ring 17 and the vacuum suction cup 18 to move. When the vacuum suction cup 18 contacts the blocking rod, the oil suction ring 17 is fitted onto the exposed end of the valve body. The vacuum pump 35 operates, which causes the vacuum suction cup 18 to connect with the blocking rod under negative pressure. When the hydraulic telescopic rod 20 retracts to below the baffle, it drives the blocking rod to move, and the blocking rod separates from the processed valve body. The lifting hydraulic rod 2 extends, causing the electromagnet 6 to move downwards until it contacts the top of the upper clamping block 5. At this point, the electromagnet 6 is energized, while the electromagnet 27 is de-energized. The electromagnet 6 and the upper clamping block 5 are magnetically attracted to each other. The retraction of the lifting hydraulic rod 2 separates the upper clamping block 5 from the lower clamping block 4. The hydraulic telescopic rod 14 extends, causing the cutting base 3 to move, facilitating the removal and placement of the valve body.
