Description

Technical Field

[0001] The present invention relates to the technical field of valve drilling, and specifically provides a waste chip recycling type marine valve drilling device. Background Art

[0002] Marine valves are devices used to control the pressure, flow rate, and flow direction of fluids in ship pipelines to meet the ship's environmental conditions; valves are control devices for fluid pipelines, used to connect or cut off the flow of pipeline media, change the flow and flow direction of the media, regulate the pressure and flow rate of the media, and protect the normal operation of pipeline equipment.

[0003] In the field of marine valve manufacturing, drilling is a core process to ensure the accuracy of the valve fluid passage and sealing performance. The traditional process usually follows the processing flow of "casting blank → end face milling → multi-axis drilling"; however, during the drilling process, metal chips generated at the high-speed drilling stage, due to the high toughness characteristics of marine valve materials such as stainless steel and copper alloy, continuous spiral or sheet chips are easily formed on the contact surface between the drill bit cutting edge and the workpiece, and spread outward from the processing area under the action of centrifugal force and cutting fluid flushing; these chips will not only adhere to the workpiece positioning surface and the fixture base surface, but may also embed in the clamping contact area of the subsequent workpiece; the residual chips form local point contact between the workpiece and the processing table, damaging the flatness of the clamping surface, resulting in the deviation of the drilling axis, directly affecting the coaxiality of the valve flange hole group and the passing rate of the sealing performance test; traditional cleaning requires manual use of independent cleaning equipment for cleaning, which is more cumbersome and time-consuming, and the metal chips adhere to the surface of the processing table under the action of the cutting fluid, making it difficult to clean and remove; moreover, rare metals need to be added to marine valves working in some special environments (such as deep sea or nuclear power systems), and the chips generated during the processing need to be recycled to reduce material waste. Summary of the Invention

[0004] The purpose of the present invention is to provide a waste chip recycling type marine valve drilling device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A waste chip recycling type marine valve drilling device, including a fixed seat with an installation groove on its surface, a processing table with a plurality of fixing grooves on its surface, a valve body fixedly arranged on the surface of the processing table through a fixture, a moving arm, a cooling pipe, and a drill bit; The surface of the fixed seat is connected to a cleaning tube with an inclined surface close to the valve body through a retractable driving member, and a cleaning port is opened on the cleaning tube close to the valve body. A retractable connecting tube is connected to the surface of the cleaning tube, and a water supply tank is fixedly connected to the installation groove. A one-way valve is provided on the surface of the water supply tank and the inside of the connecting tube. A sliding plate is slidably connected to the inside of the water supply tank through a spring, and a pulling rope is fixedly connected to the bottom of the cleaning tube. The pulling rope passes through the fixed groove and extends to the installation groove, then passes through the water supply tank and is connected to the sliding plate. When the cleaning tube moves to the side away from the valve body, the sliding plate can be driven to move by the pulling rope, and the end of the cooling tube is set to a flat mouth.

[0006] As a further solution of the present invention, the surface of the cleaning tube is rotatably connected to a rotating rod that penetrates the cleaning tube, the rotating rod is located on the outer surface of the cleaning tube and is fixedly connected to a roller that fits the surface of the fixed seat, the rotating rod is located on the inner surface of the cleaning tube and is fixedly connected to a limiting column, the limiting column is located in the cleaning port, and the surface of the limiting column is provided with a plurality of grooves for transferring cutting fluid.

[0007] As a further solution of the present invention, a fixed rod is fixedly connected to the inside of the cleaning port, and a plurality of toggle rods are elastically hinged on the surface of the fixed rod. One end of the toggle rod extends to the position of the limiting column and the other end extends to the surface of the processing table. The surface of the limiting column is fixedly connected with an arc rod corresponding to the position of the toggle rod for guiding the rotation of the toggle rod.

[0008] As a further solution of the present invention, a positioning plate for positioning the valve body is fixedly mounted on the surface of the processing table.

[0009] As a further solution of the present invention, the cleaning tube is divided into two elastic telescopic tubes from the middle position, the fixed rod and the rotating rod are both telescopic, and guide plates are fixedly connected to the left and right sides of the cleaning tube corresponding to the positioning plate position, and the guide plates are used to guide and squeeze the cleaning tube to contract through the positioning plate when the cleaning tube moves to the positioning plate position.

[0010] As a further solution of the present invention, an inwardly recessed gathering groove is provided in the middle of the positioning plate, and a plurality of through grooves penetrating the positioning plate and extending to the side of the positioning plate are provided on the inner wall of the gathering groove.

[0011] As a further solution of the present invention, an arc-shaped protective net is fixedly connected to the surface of the gathering trough.

[0012] As a further solution of the present invention, two L-shaped filter plates with one side being an inclined surface are fixedly connected inside the installation groove, and the filter plates are located below the two ends of the processing table.

[0013] As a further solution of the present invention, a cleaning door is provided on the surface of the fixed seat corresponding to the position of the filter plate.

[0014] As a further solution of the present invention, a drainage block with an inclined upper end for guiding the cutting fluid to flow toward one side of the water replenishment tank is fixedly connected to the bottom of the installation groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention utilizes a cleaning pipe, a cleaning port and a water supply tank during drilling processing of a marine valve. When the cleaning pipe moves, the cutting fluid flowing from the water supply tank to the cleaning pipe is gradually ejected through the cleaning port. The cutting fluid ejected from the cleaning port can efficiently flush out metal debris attached to the surface of the processing table and separate the metal debris from the surface of the processing table. Subsequently, the metal debris flows to the fixed groove along with the cutting fluid and flows along the fixed groove to the outside of the processing table. The cutting fluid falls into the installation groove with the metal debris, thereby ensuring that the surface of the processing table can be cleaned after the valve body is processed, and avoiding that the metal debris attached to the surface of the processing table cannot be removed, thereby causing the valve body to tilt during subsequent installation, affecting the verticality during drilling.

[0016] In the process of cleaning the processing table of the present invention, when the limiting column and the groove rotate inside the cleaning port, the groove can intermittently discharge the cutting fluid inside the cleaning tube out of the cleaning tube, thereby reducing the flow rate and impact of the cutting fluid, and avoiding the cutting fluid sprayed from the cleaning tube from flowing at a fast speed to disperse the metal debris to the outside of the installation groove, making it impossible to collect the metal debris and affecting the cleanliness of the working environment.

[0017] In the process of cleaning the processing table, the present invention utilizes the arc rod and the toggle rod to toggle the metal debris on the surface of the processing table to both sides into the fixed groove when the cleaning tube moves, and cooperates with the cutting fluid flowing out of the cleaning port to ensure that the metal debris on the surface of the processing table is removed, thereby avoiding that a large amount of metal debris accumulates on the surface of the processing table when the cleaning tube moves and cannot be flushed away, thereby affecting the subsequent installation and drilling of the valve body.

DETAILED DESCRIPTION

[0020] See also Figures 1-9 The present invention provides a technical solution: a waste chip recovery type marine valve drilling processing device, comprising a fixing seat 2 with a mounting groove 1 on the surface, a processing table 4 with a plurality of fixing grooves 3 on the surface, a valve body 6 fixedly arranged on the surface of the processing table 4 by a clamp 5, a moving arm 7, a cooling pipe 8 and a drill bit 9; The surface of the fixed seat 2 is connected with a cleaning pipe 11 with an inclined surface close to the valve body 6 through a retractable driving member 10, and a cleaning port 12 is opened on the side of the cleaning pipe 11 close to the valve body 6. The surface of the cleaning pipe 11 is connected with a retractable connecting pipe 13. A water replenishing tank 14 is fixedly connected in the installation groove 1. A one-way valve 15 is arranged on the surface of the water replenishing tank 14 and inside the connecting pipe 13. A sliding plate 17 is slidably connected to the inside of the water replenishing tank 14 through a spring 16. A pulling rope 18 is fixedly connected to the bottom of the cleaning pipe 11. The pulling rope 18 passes through the fixed groove 3 and extends to the installation groove 1, then passes through the water replenishing tank 14 and is connected to the sliding plate 17. When the cleaning pipe 11 moves to the side away from the valve body 6, the sliding plate 17 can be driven to move by the pulling rope 18, and the end of the cooling pipe 8 is set as a flat mouth; During the drilling process of marine valves, first, the fixture 5 is used to fix the valve body 6 on the surface of the processing table 4 through cooperation with the fixing groove 3. Subsequently, the moving arm 7 drives the drill bit 9 to move above the valve body 6 and drill the valve body 6. The cooling pipe 8 sprays the cutting fluid onto the surface of the drill bit 9, and the flat mouth design at the end of the cooling pipe 8 causes the cutting fluid to spray out in a water curtain shape. On the one hand, it can expand the spraying range of the cutting fluid to wash and clean the metal chips on the surface. On the other hand, it can block the flying metal chips and slow down the speed of the metal chips, thereby reducing the flying range of the metal chips. The cutting fluid sprayed by the cooling pipe 8 falls onto the surface of the processing table 4 and flows into the installation groove 1 along the fixing groove 3. Subsequently, after the processing on one side of the valve body 6 is completed, the fixture 5 needs to be removed and the valve body 6 needs to be taken out. Then, the driving member 10 drives the cleaning pipe 11 to move on the surface of the processing table 4, the pulling rope 18 gradually relaxes, and the sliding plate 17 slides inside the water replenishing tank 14 under the action of the spring 16, squeezing the cutting fluid inside the water replenishing tank 14 to flow through the one-way valve 15 and the connecting pipe 13 into the cleaning pipe 11, and gradually spraying out through the cleaning port 12 during the movement of the cleaning pipe 11. The cutting fluid sprayed out from the cleaning port 12 can efficiently wash the metal chips attached to the surface of the processing table 4 and make the metal chips separate from the surface of the processing table 4. Subsequently, the metal chips flow along with the cutting fluid to the fixing groove 3 and then flow out of the processing table 4 along the fixing groove 3. The cutting fluid with the metal chips falls into the installation groove 1, ensuring that the surface of the processing table 4 can be cleaned after the valve body 6 is processed, avoiding the situation that the metal chips attached to the surface of the processing table 4 cannot be removed, which may cause the valve body 6 to tilt during subsequent installation and affect the perpendicularity during drilling. Subsequently, after the surface of the processing table 4 is cleaned, the driving member 10 contracts to drive the cleaning pipe 11 to move in the reverse direction. The cleaning pipe 11 pulls the sliding plate 17 to move inside the water replenishing tank 14 through the pulling rope 18, and the cutting fluid inside the installation groove 1 can enter the water replenishing tank 14 through the one-way valve 15 to supplement the cutting fluid inside the water replenishing tank 14 to ensure the flushing and cleaning of the processing table 4 during subsequent processing.

[0021] During the cleaning process of the surface of the processing table 4, the cutting fluid sprayed out from the cleaning port 12 has a relatively high speed and is likely to wash the metal chips out of the installation groove 1. As a further solution of the present invention, a rotating rod 19 penetrating the cleaning pipe 11 is rotatably connected to the surface of the cleaning pipe 11. A roller 20 that fits the surface of the fixed seat 2 is fixedly connected to the outer surface of the rotating rod 19 outside the cleaning pipe 11. A limiting column 21 is fixedly connected to the inner surface of the rotating rod 19 inside the cleaning pipe 11. The limiting column 21 is located inside the cleaning port 12, and a plurality of grooves 22 for transferring the cutting fluid are formed on the surface of the limiting column 21; During the cleaning process of the processing table 4, the movement of the cleaning tube 11 drives the rotating rod 19 and the roller 20 to move synchronously, and the roller 20 drives the rotating rod 19 and the limiting column 21 to rotate simultaneously along the surface of the fixed seat 2. During the rotation of the limiting column 21, the groove 22 rotates inside the cleaning port 12 to intermittently discharge the cutting fluid inside the cleaning tube 11 from the cleaning tube 11, thereby reducing the flow rate and impact of the cutting fluid, and avoiding the cutting fluid sprayed from the cleaning tube 11 from flowing at a fast speed to disperse the metal debris to the outside of the mounting groove 1, making it impossible to collect the metal debris and affecting the cleanliness of the working environment.

[0022] In the process of cleaning the surface of the processing table 4, when the cleaning tube 11 is cleaning, a lot of metal debris is accumulated on the surface of the processing table 4, which is difficult to be washed away by the cutting fluid. As a further solution of the present invention, a fixing rod 23 is fixedly connected inside the cleaning port 12, and a plurality of toggle rods 24 are elastically hinged on the surface of the fixing rod 23. One end of the toggle rod 24 extends to the position of the limiting column 21 and the other end extends to the surface of the processing table 4. The surface of the limiting column 21 is fixedly connected to the position of the toggle rod 24 corresponding to the position of the toggle rod 24, and is used to guide the rotation of the toggle rod 24. During the cleaning process of the processing table 4, when the cleaning tube 11, the roller 20 and the rotating rod 19 move, the rotating rod 19 drives the limiting column 21 and the arc rod 25 to rotate. The rotation of the arc rod 25 can intermittently push the toggle rod 24 to rotate, thereby toggling the metal debris on the surface of the processing table 4 to both sides into the fixed groove 3. The cutting fluid flowing out of the cleaning port 12 can ensure that the metal debris on the surface of the processing table 4 is removed, thereby avoiding the accumulation of a large amount of metal debris on the surface of the processing table 4 when the cleaning tube 11 moves and cannot be flushed away, thereby affecting the subsequent installation and drilling of the valve body 6.

[0023] During the cleaning process of the processing table 4, the clamp 5 needs to be removed when the valve body 6 is picked up, and the valve body 6 needs to be repositioned when it is installed again. As a further solution of the present invention, a positioning plate 26 for positioning the valve body 6 is fixedly installed on the surface of the processing table 4; During the cleaning process of the processing table 4, the positioning plate 26 can position the valve body 6 to ensure that the valve body 6 is in the same position each time it is installed, thereby reducing positioning adjustments during each installation and improving processing efficiency.

[0024] In the process of cleaning the processing table 4, the positioning plate 26 blocks the cleaning tube 11 when the cleaning tube 11 cleans the processing table 4. As a further solution of the present invention, the cleaning tube 11 is divided into two elastic telescopic tubes from the middle position. The fixed rod 23, the rotating rod 19 and the limiting column 21 are all retractable. The left and right sides of the cleaning tube 11 are fixedly connected to the corresponding positions of the positioning plate 26. The guide plate 27 is used to guide the cleaning tube 11 to contract through the positioning plate 26 when the cleaning tube 11 moves to the position of the positioning plate 26; During the cleaning process of the processing table 4, when the cleaning pipe 11 moves to the position of the positioning disk 26, the guiding plate 27 first contacts the surface of the positioning disk 26. Under the extrusion of the positioning disk 26, the guiding plate 27 causes the cleaning pipe 11 to contract, so as to cross the positioning disk 26 and clean the surface of the processing table 4, ensuring the cleanliness around the positioning disk 26. The rotating rod 19, the fixed rod 23 and the limiting column 21 contract synchronously with the cleaning pipe 11. Subsequently, when the cleaning pipe 11 moves in the reverse direction, the guiding plate 27 on the other side of the cleaning pipe 11 can cause the cleaning pipe 11 to contract again and cross the positioning disk 26.

[0025] After the processing of the valve body 6 is completed, a large amount of cutting fluid and metal chips are likely to accumulate on the surface of the processing table 4 around the valve body 6. When the valve body 6 is picked up, the cutting fluid and metal chips flow towards the edge position of the positioning disk 26, and it is difficult to clean the metal chips in the angle between the positioning disk 26 and the processing table 4. As a further solution of the present invention, a gathering groove 28 that is recessed inward is provided in the middle of the positioning disk 26, and a plurality of through grooves 29 that penetrate through the positioning disk 26 and extend to the side surface of the positioning disk 26 are provided on the inner wall of the gathering groove 28; During the processing of the valve body 6, the cutting fluid sprayed onto the middle of the positioning disk 26 can be gathered inside the gathering groove 28. The valve body 6 is located outside the positioning disk 26, and the through groove 29 is blocked. Subsequently, when the valve body 6 is lifted upward after the processing is completed, the through groove 29 is exposed, and the cutting fluid in the gathering groove 28 flows from the side surface of the positioning disk 26 to the surroundings through the through groove 29, so as to be able to push the metal chips around the positioning disk 26 to the surroundings, avoiding the cutting fluid and metal chips around the valve body 6 moving towards the periphery of the positioning disk 26 when the valve body 6 moves upward and increasing the cleaning difficulty.

[0026] During the processing of the valve body 6, the metal chips generated by the processing are likely to block the through groove 29 when falling into the gathering groove 28. As a further solution of the present invention, an arc-shaped protective net 30 is fixedly connected to the surface of the gathering groove 28; During the processing of the valve body 6, the protective net 30 can protect the gathering groove 28 and the end of the through groove 29, preventing the through groove 29 from being blocked by the scattered metal chips.

[0027] During the processing of the valve body 6, the metal chips falling into the installation groove 1 cannot be centrally collected. As a further solution of the present invention, two L-shaped filter plates 31 with one side being a slope are fixedly connected inside the installation groove 1, and the filter plates 31 are located below both ends of the processing table 4; During the processing of the valve body 6, when metal debris flows along the fixing groove 3 to the inside of the installation groove 1 with the cutting fluid, the cutting fluid and the metal debris fall onto the surface of the filter plate 31, and the cutting fluid is filtered and falls to the bottom of the installation groove 1. The metal debris is blocked by the filter plate 31, which is conducive to the centralized collection of the metal debris and separation from the cutting fluid, facilitating subsequent centralized processing and recycling. In addition, filtering the metal debris can reduce the influence of the metal debris on the one-way valve 15, thereby ensuring the water inlet effect of the water supply tank 14.

[0028] During the processing of the valve body 6, when a lot of metal debris accumulates on the surface of the filter plate 31 and is difficult to be cleared out of the installation groove 1, as a further solution of the present invention, a cleaning door 32 is provided on the surface of the fixing seat 2 corresponding to the position of the filter plate 31; During the processing of the valve body 6 , when a lot of metal debris is gathered on the surface of the filter plate 31 , the metal debris can be directly cleaned out of the filter plate 31 through the cleaning door 32 , thereby ensuring the filtering effect of the filter plate 31 .

[0029] During the cleaning process of the processing table 4, when the cutting fluid in the installation groove 1 is less, it is difficult for the water supply tank 14 to replenish the cutting fluid in time. As a further solution of the present invention, a drainage block 33 with an inclined upper end for guiding the cutting fluid to flow to one side of the water supply tank 14 is fixedly connected to the bottom of the installation groove 1; During the cleaning process of the processing table 4, the cutting fluid flowing into the installation groove 1 can be gathered at the position of the water replenishing tank 14 under the guidance of the drainage block 33, ensuring that the cutting fluid can be replenished in time in the water replenishing tank 14 during use, thereby avoiding the situation where the cutting fluid in the installation groove 1 is insufficient and the water replenishing tank 14 cannot be replenished in time, thereby affecting the cleaning of the processing table 4.
