[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0022] like Figures 1 to 7 As shown, the present invention provides a valve body processing equipment, comprising: a machine base 1, a worktable 11 fixedly installed on the machine base 1, a clamp 12 fixedly installed on the worktable 11, a linear motion module 2 fixedly installed on the machine base 1, a grinding mechanism 3 for grinding the valve body, and a cooling mechanism 4 for reducing the grinding temperature.

[0023] The valve body is placed on the workbench 11 for grinding. Then, the valve body is clamped by the clamp 12. The linear motion module 2 drives the grinding mechanism 3 to move closer to the valve body and grind the sealing surface of the inner wall of the valve body. During the grinding process, the cooling mechanism 4 is used to cool the valve body to ensure the grinding effect.

[0024] The grinding mechanism 3 includes: an electromagnet 31 rotatably mounted on the worktable 11, a fixed shaft 32 fixedly mounted on the electromagnet 31, a connecting rod 33 rotatably mounted on the fixed shaft 32, a fixed rod 34 rotatably mounted on the connecting rod 33, a grinding plate 36 fixedly mounted on the fixed rod 34, a connecting rod 37 rotatably mounted on the fixed rod 34, and an adjusting block 38 rotatably mounted on the connecting rod 37. A threaded rod 39 is threadedly connected to the adjusting block 38.

[0025] In use, the valve body is placed around the grinding plate 36, and then the valve body is clamped from the outside by the clamp 12. The electromagnet 31 is magnetically fixed to the worktable 11. Then, the threaded rod 39 is rotated to move the adjusting block 38. At the same time, the fixing rod 34 and the connecting plate 35 are moved towards the inner wall of the valve body through the connecting rod 37 and the connecting rod 33 until they are in contact with the inner wall of the valve body. Then the electromagnet 31 is turned off, and the threaded rod 39 is rotated again to make the threaded rod 39 drive the grinding plate 36 to rotate synchronously to grind the sealing surface of the inner wall of the valve body, thus completing the grinding of the valve body sealing surface. In addition, when the adjusting block 38 moves, it will squeeze the spring. When the threaded rod 39 reverses, the spring will return to its original position, which helps the adjusting block 38 to return to its original position.

[0026] The grinding plate 36 of the grinding mechanism 3 of this application adopts a three-jaw structure with 120° equal division. When the pressure of a single jaw fluctuates, the adjacent two jaws automatically compensate through force transmission. The grinding plate 36 is an arc-shaped plate, and its curvature fits the sealing surface of the valve body, which can ensure the grinding accuracy. The grinding plate 36 is set with multiple sets, which is more efficient than single-point grinding.

[0027] It should be noted that the grinding mechanism 3 further includes: an adjusting shaft 393 and a motor 396 fixedly mounted on the machine base 1. The adjusting shaft 393 has a slot 398 on its surface, and a slider 399 is fixedly mounted on the adjusting shaft 393. The slider 399 is fixedly mounted on the linear motion module 2 and is rotatably connected to the adjusting shaft 393 via the slot 398. The adjusting shaft 393 has a sliding groove 394 and a limiting groove 395. The output shaft of the motor 396 and a limiting block 397 are slidably connected to the sliding groove 394 and the limiting groove 395, respectively. The output shaft of the motor 396 is fixedly connected to the limiting block 397. A connecting block 392 is fixedly mounted at the end of the adjusting shaft 393, and a connecting hole 391 is provided at the end of the threaded rod 39. The connecting hole 391 cooperates with the connecting block 392. During use, the linear motion module 2 drives the slider 399 to move, causing the adjusting shaft 393 to drive the connecting block 392 into the connecting hole 391. At the same time, the limiting block 397 slides in the limiting groove 395, and the output shaft of the motor 396 slides in the slide groove 394 to prevent the motor 396 from moving, which would cause the grinding plate 36 to shake when the motor 396 drives it to rotate, thus affecting the grinding effect on the valve body.

[0028] It should be added that the end of the connecting hole 391 is chamfered, which makes it easier to connect with the connecting block 392. When the adjusting shaft 393 rotates, it rotates on the surface of the slider 399 through the slot 398, which avoids interference between the slider 399 and the adjusting shaft 393. In addition, a spray nozzle for spraying coolant can be installed on the adjusting shaft 393. When the grinding plate 36 grinds the valve body, the spray nozzle sprays coolant into the valve body at the same time to cool it down, so as to avoid affecting the grinding effect of the valve body sealing surface under high temperature.

[0029] Marine valves are used in environments where they are exposed to seawater corrosion, which puts their corrosion resistance and strength to a greater test. Therefore, stainless steel is generally used as the material for existing valves. However, stainless steel is prone to work hardening during grinding. Work hardening is a phenomenon in which the hardness and strength of a metal increase due to the increased dislocation density during plastic deformation, but the plasticity and toughness decrease. This can seriously affect the accuracy of the valve body sealing surface.

[0030] The cooling mechanism 4 includes: a second slider 414 fixedly mounted on the linear motion module 2, and a coolant tank 41 fixedly mounted on the second slider 414. A drive shaft 42 is rotatably mounted on the coolant tank 41, and blades 43 are fixedly mounted on the drive shaft 42. Two sets of blades 43 are provided on the drive shaft 42, one set being fan blades near the valve body and the other set being stirring blades. A power source is fixedly mounted at one end of the drive shaft 42. When the motor 396 drives the grinding plate 36 to grind the valve body, the power source is activated to drive the drive shaft 42 to rotate, thereby causing the blades 43 ( The fan blades rotate, driving the airflow towards the power source, allowing outside air to enter the coolant tank 41 through the valve body. This helps to cool the valve body during the grinding process, ensuring the grinding effect. In addition, a large amount of iron filings are generated during the grinding process. If the iron filings are not removed, it will affect the grinding effect on the valve body sealing surface. Therefore, when the blades 43 rotate, they drive the airflow, which carries the iron filings in the valve body into the coolant tank 41. This not only cools the valve body but also removes the iron filings generated during the grinding process, improving the grinding effect on the valve body.

[0031] In addition, if coolant is sprayed out from the nozzle during the grinding process, the coolant mixes with the iron filings and is discharged into the coolant tank 41, causing the coolant to be directly contaminated and unable to be recycled. Moreover, the mixture needs to be treated before being discharged, which increases the cost. Therefore, the surface of the coolant tank 41 is provided with an exhaust port 411, a cooler 412 is fixedly installed on the outer wall of the coolant tank 41, and an adsorbent 413 is fixedly installed on the inner wall of the coolant tank 41. The adsorbent 413 is a sponge-like porous structure.

[0032] When the mixture flows into the coolant tank 41, it comes into contact with the blades 43 (fan blades). The rotating blades 43 disperse the mixture toward the adsorbent 413. After the adsorbent 413 adsorbs the mixture, the iron filings in the mixture are blocked by the porous structure of the adsorbent 413, while the coolant flows away under gravity, thus achieving the separation of coolant and iron filings. This allows the treated coolant to be reused, saving costs.

[0033] After the coolant flows to the bottom of the coolant tank 41, the cooler 412 cools it down, making the coolant cool down quickly and easy to use. The airflow brought into the coolant tank 41 by the blades 43 will be discharged outward through the exhaust port 411. The exhaust port 411 is located close to the cooler 412, which can drive the airflow around the cooler 412 and ensure the effectiveness of the cooler 412.

[0034] Furthermore, a tripod 415 is fixedly installed on the coolant tank 41, and a filter screen 416 is fixedly installed on the tripod 415. A hose 417 is connected to the filter screen 416. When it is necessary to recover the coolant in the coolant tank 41, the coolant inside the coolant tank 41 is drawn through the hose 417 and discharged outward after secondary filtration by the filter screen 416, ensuring the purity of the coolant. Moreover, the tripod 415 has a design with two intersecting inclined surfaces, which prevents iron filings in the coolant from clogging the filter screen 416 and affecting the discharge of coolant, resulting in good performance.

[0035] In summary, the rotation of blade 43 drives airflow, which on the one hand cools the valve body during the grinding process to ensure the grinding effect of the valve body, and also carries the iron filings in the valve body into the coolant tank 41 to prevent the iron filings from affecting the grinding of the valve body. On the other hand, it can disperse the mixture of coolant and iron filings, and separate the coolant and iron filings under the action of the adsorbent 413, so as to realize the recycling and reuse of coolant and reduce costs.

[0036] It should be noted that the mixture may enter the interior of the coolant tank 41 through the gap between the blade 43 and the coolant tank 41, causing the rotation of the coolant tank 41 to fail to completely disperse the mixture, thus affecting the processing of the mixture. Therefore, a guide frame 423 is slidably connected to the inner wall of the coolant tank 41. The guide frame 423 has an inclined surface. When the mixture enters the interior of the coolant tank 41, it first contacts the guide frame 423. Under the influence of the inclined surface of the guide frame 423, the mixture is guided to the blade 43, thereby improving the processing effect of the blade 43 on the mixture.

[0037] It should be added that the guide frame 423 is fixedly installed with a guide block 422, the drive shaft 42 is provided with a guide groove 421, the guide block 422 cooperates with the guide groove 421, and the guide frame 423 is fixedly installed with a pressing plate 424. When the drive shaft 42 rotates, under the limit of the guide groove 421, the guide block 422 drives the guide frame 423 to move up and down reciprocally, so that the pressing plate 424 moves back and forth synchronously. When the pressing plate 424 moves downward, it squeezes the adsorbent 413, causing the adsorbent 413 to discharge the coolant. When the pressing plate 424 moves upward, the adsorbent 413 resets and continues to process the mixture. This helps the adsorbent 413 to discharge the coolant and avoids affecting the processing effect of the mixture.

[0038] In addition, the power source is fixedly installed on the machine base 1. When the linear motion module 2 drives the coolant tank 41 to move, it simultaneously drives the cooler 412 and the adsorbent 413 to move synchronously. The position of the other set of blades 43 (stirring blades) remains unchanged, so that the blades 43 enter the coolant. At this time, the power source is started to drive the blades 43 to rotate, which can stir the coolant. After stirring, it is allowed to stand, which can improve the separation effect of coolant and iron filings and ensure the discharge effect of coolant. The power source is preferably an electric motor.

[0039] When the blade 43 (stirring blade) drives the coolant to rotate, the flow of coolant can flush the filter screen 416, which is beneficial to unblocking the filter screen 416, reducing the clogging of the filter screen 416, thereby reducing the maintenance cost of the filter screen 416 and achieving good results.

[0040] Finally, the linear motion module 2 is a heavy-duty linear guide module, which simultaneously moves slider 1 399 and slider 2 414. On one hand, it completes the connection of connecting hole 391 and connecting block 392, so that motor 396 can drive grinding plate 36 to grind the valve body. On the other hand, it can move coolant tank 41, so that blade 43 changes working state for better effect. In detail, when the linear motion module 2 moves slider 1 399 and slider 2 414 downward synchronously, connecting hole 391 and connecting block 392 are connected, which can grind the valve body. At the same time, blade 43 disperses the mixture. When the linear motion module 2 moves slider 1 399 and slider 2 414 upward synchronously, connecting block 392 is connected and separated. At the same time, blade 43 is in the coolant and can stir the coolant.

[0041] When the power source drives the drive shaft 42 to rotate, it can drive the blades 43 to rotate. The blades 43 can drive the airflow into the coolant tank 41 and stir the coolant. The centrifugal force generated during stirring can treat the coolant, resulting in better performance. Furthermore, when the drive shaft 42 rotates, it can also cause the extrusion plate 424 to move up and down, thereby extruding the adsorbent 413 to accelerate the treatment effect of the adsorbent 413 on the mixture.
