Description

Technical Field

[0001] This invention relates to the field of valve body processing technology, specifically to an automated grinding device and method for processing flat gate valve bodies. Background Technology

[0002] A grinding apparatus for processing the body of a flat gate valve is a device specifically designed for precision machining of the valve body surface. Through efficient grinding, it removes unevenness, defects, and oxide layers from the valve body surface, ensuring a smooth and flat surface, thus improving sealing performance and service life.

[0003] Chinese patent CN217255259U discloses a grinding device for processing the body of a flat gate valve, including a worktable, a first lead screw, a slider, and two grinding mechanisms. The worktable is horizontally positioned; the first lead screw is located in a through groove on the worktable and is rotatably connected to the worktable; a power component is located on one side of the first lead screw, driving the first lead screw to rotate; the slider is mounted on the first lead screw and is threadedly connected to it; the slider is slidably connected to the worktable; a lower clamp is located on the upper side of the slider and is connected to the lower clamp by screws; an upper clamp is located on the upper side of the lower clamp and is connected to the upper clamp by screws; the two grinding mechanisms are symmetrically arranged on the front and rear sides of the slider. This patent uses the upper and lower clamps to hold the valve body, and the grinding mechanisms on both sides of the valve body simultaneously grind the valve body, avoiding grinding errors caused by repeated installation.

[0004] However, the current grinding device has the following problems: the grinding device only grinds the two end faces of the flat gate valve body by rotating the grinding disc. The rotating grinding disc can usually only provide movement in one direction, which can easily lead to uneven grinding. Especially when there are some minor unevennesses on the end face of the valve body, the rotating grinding may not be able to uniformly process the entire contact surface, resulting in excessive wear in some areas while other parts are not sufficiently ground. Therefore, we propose an automated grinding device and method for processing flat gate valve bodies. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automated grinding device and method for processing flat gate valve bodies, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automated grinding device for processing flat gate valve bodies, comprising a processing table, a positioning component disposed at the top center of the processing table, the positioning component comprising a placement frame fixed to the top of the processing table, a bidirectional screw first rotatably mounted laterally on the lower inner wall of the placement frame, clamping plates threadedly connected to opposite threaded surfaces of the bidirectional screw first, and the clamping plates slidably mounted on the bottom inner wall of the placement frame, a driving component disposed at the top of the processing table, the driving component comprising a bidirectional screw second, a groove formed at the top of the processing table, the bidirectional screw second rotatably mounted on the processing table. Inside the groove of the workbench, movable plates are threadedly connected to the opposite threaded surfaces of the bidirectional screw two, and the movable plates are slidably installed inside the groove of the workbench. The bidirectional screw two is driven by a drive motor, and the movable plates are the moving ends of the drive assembly. Grinding components are provided at both moving ends of the drive assembly. The grinding components include a rotary motor and a wave-shaped annular groove disk. The rotary motor is fixed to the outer wall above a single moving end of the drive assembly. A square shell is fixed to the output end of the rotary motor. Several push rods are evenly and equidistantly intersecting and slidably installed on the top and bottom of the square shell. Several push rods on the upper and lower sides are close to each other. Each component is fixed with a grinding plate, which is vertically slidably mounted on the side of the square shell near the positioning component. Connecting plates are fixed between the upper and lower sides of several push rods that are far apart from each other. Fixing posts are fixed to the sides of two connecting plates that are far from the positioning component. The wavy annular grooved plate is fixed to the outer wall of a single moving end of the drive component. A wavy annular groove is formed on the outer wall of the wavy annular grooved plate. Two fixing posts are slidably mounted inside the wavy annular groove of the wavy annular grooved plate. The side of the grinding plate far from the positioning component and the side of the connecting plate near the positioning component are on the same horizontal plane. A bidirectional screw drives the moving plate towards the flat gate valve body. The moving plate rotates... The rotary motor and the square shell drive the grinding plate to approach the two end faces of the flat gate valve body. Then, the rotary motor drives the square shell to rotate the grinding plate. At this time, the grinding plate can rotate to grind the two end faces of the flat gate valve body. At the same time, while the grinding plate is rotating, it will also drive the fixed column to rotate through the push rod. The fixed column will slide along the inside of the wavy annular groove of the wavy annular groove plate. Under the restriction of the wavy annular groove of the wavy annular groove plate, the fixed column will push the connecting plate to drive the push rod to move. The push rod drives the grinding plate to move back and forth towards the center of the square shell, so that the grinding plate can also dynamically move to grind the two end faces of the flat gate valve body while rotating.

[0007] According to the above technical solution, a paste-applying device is provided at the square shell. The paste-applying device includes a ring tube and a grinding paste box. The ring tube is fixed to the outside of the corrugated annular groove plate by a bracket. The grinding paste box is fixed to the side of the corrugated annular groove plate away from the positioning component. A pump is fixed to the top of the grinding paste box. A U-shaped tube is fixed to the top of the pump. The end of the U-shaped tube away from the pump is fixed to the top of the ring tube. An annular plate is rotatably installed on the inner wall of the ring tube. Four flexible hoses are fixed to the inner wall of the annular plate. A straight pipe is fixed between each pair of opposing flexible hoses. Several long spray pipes are fixed to the sides of the two straight pipes that are close to each other. Several short nozzles are fixed on the opposite sides of each straight pipe. Two straight pipes are staggered vertically. The long and short nozzles corresponding to the two straight pipes are staggered and fixed to the outer wall of the grinding plate. The pump is used to draw grinding paste from the grinding paste tank and transfer it to the ring pipe through the U-shaped tube. While the grinding plate is grinding the two end faces of the flat gate valve body, the operator starts the pump. The pump draws grinding paste from the grinding paste tank and transfers it to the ring pipe through the U-shaped tube. The ring pipe then transfers the grinding paste through the hose and straight pipe to the long and short nozzles for spraying, so that the grinding paste sprayed from the long and short nozzles is applied to the two end faces of the flat gate valve body.

[0008] According to the above technical solution, a baffle device is provided at the annular tube. The baffle device includes four side plates, which are respectively fixed on both sides of the annular tube near the positioning component. A sliding rod is slidably installed through the exterior of each of the four side plates. A baffle is fixed on the side of the sliding rod away from the side plate. A spring is provided between the baffle and the side plate. An L-shaped inclined rod is fixed on the side of each of the four baffles near the positioning component. The L-shaped inclined rod is located on the side of the baffle near the center of the annular tube. When the moving plate moves towards the flat gate valve body, the moving plate drives the side plate to move synchronously through the wavy annular groove and the annular tube. The side plate drives the L-shaped inclined rod to move along with it through the sliding rod and the baffle. When the inclined surface of the L-shaped inclined rod moves to the end face of the flat gate valve body, the end face of the flat gate valve body pushes the inclined surface of the L-shaped inclined rod to move the baffle and the sliding rod towards the side plate. The spring between the side plate and the baffle is compressed.

[0009] A method for using an automated grinding device for processing the body of a flat gate valve includes the following steps:

[0010] S1. Place the flat gate valve body to be processed on the placement rack. The operator rotates the first double-acting screw, which drives the two clamping plates to move towards the flat gate valve body, thereby fixing the flat gate valve body to the placement rack.

[0011] S2. Drive the bidirectional screw two to rotate through the drive motor. The bidirectional screw two drives the moving plate to move towards the valve body of the flat gate valve. The moving plate drives the grinding plate to move towards the two end faces of the valve body of the flat gate valve through the rotary motor and the square shell.

[0012] S3. Next, the square shell is driven by a rotary motor to rotate the grinding plate. The grinding plate can then be rotated to grind the two end faces of the flat gate valve body.

[0013] S4. At the same time, while the grinding plate is rotating, it will also drive the fixed column to rotate through the push rod. The fixed column will slide along the inside of the wavy annular groove of the wavy annular groove plate. Under the restriction of the wavy annular groove of the wavy annular groove plate, the fixed column will push the push rod to drive the grinding plate to move back and forth towards the center of the square shell, so that the grinding plate can also dynamically move to grind the two end faces of the flat gate valve body while rotating.

[0014] This invention provides an automated grinding device and method for processing the valve body of a flat gate valve. It has the following beneficial effects:

[0015] (1) By setting up the grinding components, the positioning components, driving components, rotary motor, square shell, grinding plate, push rod, fixed column, and wave-shaped annular groove disk work together to drive the grinding plate to rotate and move dynamically to grind the two end faces of the flat gate valve body. This allows the grinding plate to act on the two end faces of the flat gate valve body in multiple directions at the same time. This dynamic reciprocating motion makes the contact between different areas of the two end faces of the flat gate valve body more uniform during the grinding process, thereby effectively avoiding the problem of excessive local wear caused by single rotation and insufficient grinding in other areas.

[0016] (2) The present invention, through the setting of the paste application device, enables the grinding paste in the grinding paste tank drawn by the pump to be transferred to the ring pipe through the U-shaped tube. The ring pipe then transmits the grinding paste to the long and short spray pipes through the hose and straight pipe, so that the grinding paste sprayed from the long and short spray pipes is applied to both sides of the flat gate valve body. The spraying of the grinding paste can effectively lubricate the grinding surface and reduce the direct friction between the metal and the grinding plate during the grinding process. This not only reduces heat generation and wear, but also improves the contact efficiency between the grinding plate and both sides of the flat gate valve body. Furthermore, with the dynamic reciprocating motion of the grinding plate, the grinding plate can drive the long and short spray pipes to evenly spray the grinding paste onto both sides of the flat gate valve body. The uniform spraying of the grinding paste can maintain a stable and uniform grinding environment throughout the grinding process, ensuring that both sides of the flat gate valve body can uniformly receive the action of the abrasive during the grinding process, avoiding local excessive wear or insufficient grinding.

[0017] (3) The present invention, through the setting of the baffle device, enables the moving plate, the wave-shaped annular groove plate, the annular pipe, the side plate, the slide rod, the baffle, and the L-shaped inclined rod to cooperate. The end face of the flat gate valve body pushes the inclined surface of the L-shaped inclined rod to drive the baffle and the slide rod to move towards the side plate. The spring between the side plate and the baffle is compressed. The baffle can adapt to the size of the diameter of the end face of the flat gate valve body to block the nozzles of the long nozzle and the short nozzle on the grinding plate, thereby ensuring that the long nozzle and the short nozzle spray the grinding paste only when the grinding area needs it, so that the grinding paste is only applied to the area that needs grinding and avoids unnecessary waste.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Please see Figure 1 - Figure 12 One embodiment of the present invention is: an automated grinding device for processing flat gate valve bodies, comprising a processing table 1, a positioning component 2 disposed at the top center of the processing table 1, the positioning component 2 including a placement frame 21 fixed to the top of the processing table 1, a bidirectional screw 22 rotatably mounted laterally on the lower inner wall of the placement frame 21, clamping plates 23 threadedly connected to opposite threaded surfaces of the bidirectional screw 22, and the clamping plates 23 slidably mounted on the bottom of the inner wall of the placement frame 21, a driving component 3 disposed at the top of the processing table 1, the driving component 3 including a bidirectional screw 31, a groove being formed at the top of the processing table 1, the bidirectional screw 31 being rotatably mounted on the processing table 1. Inside the groove of the workbench 1, movable plates 32 are threadedly connected to the opposite threaded surfaces of the bidirectional screw 31. The movable plates 32 are slidably installed inside the groove of the workbench 1. The bidirectional screw 31 is driven by a drive motor 33. The movable plates 32 are the moving ends of the drive assembly 3. Grinding components 4 are provided at both moving ends of the drive assembly 3. The grinding components 4 include a rotary motor 41 and a wave-shaped annular groove disk 47. The rotary motor 41 is fixed to the outer wall above a single moving end of the drive assembly 3. A square shell 42 is fixed to the output end of the rotary motor 41. Several push rods 44 (e.g., ...) are evenly and equidistantly intersecting and slidably installed on the top and bottom of the square shell 42. Figure 6As shown), grinding plates 43 are fixed to the sides of several push rods 44 above and below that are close to each other. The grinding plates 43 are vertically slidably installed on the side of the square shell 42 near the positioning component 2. Connecting plates 46 are fixed between the sides of several push rods 44 above and below that are far from each other. Fixing posts 45 are fixed to the sides of the two connecting plates 46 that are far from the positioning component 2. A wavy annular grooved plate 47 is fixed to the outer wall of a single moving end of the drive component 3. A wavy annular groove is opened on the outer wall of the wavy annular grooved plate 47. Two fixing posts 45 are slidably installed inside the wavy annular groove of the wavy annular grooved plate 47. The side of the grinding plate 43 away from the positioning component 2 and the side of the connecting plate 46 close to the positioning component 2 are on the same horizontal plane. With the above structure, the grinding plate 43 can rotate and move dynamically to grind the two end faces of the flat gate valve body. This allows the grinding plate 43 to act on the two end faces of the flat gate valve body in multiple directions at the same time. This dynamic reciprocating motion makes the contact between different areas of the two end faces of the flat gate valve body more uniform during the grinding process, thus effectively avoiding the problem of excessive local wear caused by single rotation and insufficient grinding in other areas.

[0033] A paste application device 5 is provided at the square shell 42. The paste application device 5 includes a ring tube 51 and a grinding paste box 57. The ring tube 51 is fixed to the outside of the corrugated annular groove plate 47 by a bracket. The grinding paste box 57 is fixed to the side of the corrugated annular groove plate 47 away from the positioning component 2. A pump 58 is fixed to the top of the grinding paste box 57. A U-shaped tube 59 is fixed to the top of the pump 58. The end of the U-shaped tube 59 away from the pump 58 is fixed to the top of the ring tube 51. An annular plate 52 is rotatably installed on the inner wall of the ring tube 51. Four hoses 53 are fixed to the inner wall of the annular plate 52. A straight tube 54 is fixed between each pair of opposite hoses 53. Several long nozzles 55 are fixed to the side of the two straight tubes 54 that are close to each other. Several short nozzles 56 (e.g., ...) are fixed to the side of the two straight tubes 54 that are far from each other. Figure 11As shown), the two straight pipes 54 are arranged in an alternating vertical configuration. The corresponding long nozzles 55 and short nozzles 56 of the two straight pipes 54 are staggered and fixed to the outer wall of the grinding plate 43. The pump 58 is used to draw grinding paste from the grinding paste tank 57 and transfer it through the U-shaped pipe 59 to the ring pipe 51. Through this structure, the grinding paste sprayed from the long nozzles 55 and short nozzles 56 is applied to both ends of the flat gate valve body. The spraying of the grinding paste effectively lubricates the grinding surface, reducing direct friction between the metal and the grinding plate 43 during the grinding process. This not only... It can reduce heat generation and wear, and improve the contact efficiency between the grinding plate 43 and the two end faces of the flat gate valve body. As the grinding plate 43 moves dynamically back and forth, it can drive the long nozzle 55 and the short nozzle 56 to evenly spray the grinding paste on the two end faces of the flat gate valve body. The even spraying of the grinding paste can maintain a stable and uniform grinding environment throughout the grinding process, ensuring that the two end faces of the flat gate valve body can receive the action of the abrasive evenly during the grinding process, avoiding local excessive wear or insufficient grinding.

[0034] In use, the flat gate valve body to be processed is placed on the placement rack 21. The operator rotates the first bidirectional screw 22, which drives two clamping plates 23 to move closer to the flat gate valve body, thus fixing the flat gate valve body to the placement rack 21. The second bidirectional screw 31 is driven to rotate by the drive motor 33, which drives the moving plate 32 to move closer to the flat gate valve body. The moving plate 32, through the rotary motor 41 and the square shell 42, drives the grinding plate 43 to move closer to the two end faces of the flat gate valve body. Then, the rotary motor 41 drives the square shell 42 to rotate the grinding plate 43. At this time, the grinding plate 43 can rotate to grind the two end faces of the flat gate valve body. At the same time, the grinding plate 43 also drives the fixed plate through the push rod 44. As the fixed column 45 rotates, it slides along the inside of the wavy annular groove of the wavy annular groove plate 47. Under the constraint of the wavy annular groove of the wavy annular groove plate 47, the fixed column 45 pushes the connecting plate 46 to move the push rod 44. The push rod 44 drives the grinding plate 43 to move back and forth towards the center of the square shell 42. This allows the grinding plate 43 to dynamically move and grind the two end faces of the flat gate valve body while rotating. This allows the grinding plate 43 to act on the two end faces of the flat gate valve body in multiple directions at the same time. This dynamic reciprocating motion makes the contact between different areas of the two end faces of the flat gate valve body more uniform during the grinding process, thus effectively avoiding the problem of excessive local wear caused by single rotation and insufficient grinding in other areas.

[0035] While the grinding plate 43 grinds the two end faces of the flat gate valve body, the operator starts the pump 58. The pump 58 draws grinding paste from the grinding paste tank 57 and transfers it through the U-shaped tube 59 to the ring pipe 51. The ring pipe 51 then transmits the grinding paste through the hose 53 and the straight pipe 54 to the long nozzle 55 and the short nozzle 56 for spraying. This allows the grinding paste sprayed from the long nozzle 55 and the short nozzle 56 to coat the two end faces of the flat gate valve body. The spraying of the grinding paste effectively lubricates the grinding surface and reduces direct friction between the metal and the grinding plate 43 during the grinding process. Not only can it reduce heat generation and wear, but it can also improve the contact efficiency between the grinding plate 43 and the two end faces of the flat gate valve body. Furthermore, with the dynamic reciprocating motion of the grinding plate 43, the grinding plate 43 can drive the long nozzle 55 and the short nozzle 56 to evenly spray the grinding paste onto the two end faces of the flat gate valve body. The uniform spraying of the grinding paste can maintain a stable and uniform grinding environment throughout the grinding process, ensuring that the two end faces of the flat gate valve body can evenly receive the action of the abrasive during the grinding process, avoiding local excessive wear or insufficient grinding.

[0036] It should be noted that since the annular plate 52 and the annular tube 51 are rotatably connected, when the square shell 42 drives the long nozzle 55, short nozzle 56, straight tube 54 and hose 53 to rotate through the grinding plate 43, the presence of the annular tube 51 will not interfere with the spraying of the grinding paste at the long nozzle 55 and short nozzle 56. At the same time, since the two straight tubes 54 are staggered vertically, and the long nozzles 55 and short nozzles 56 corresponding to the two straight tubes 54 are also staggered, when the push rods 44 corresponding to the upper and lower connecting plates 46 drive the grinding plate 43 to move, the long nozzles 55 and short nozzles 56 corresponding to the two straight tubes 54 will not interfere with the movement when they are moved by the grinding plate 43.

[0037] Please see Figure 1 - Figure 12 Based on the above embodiments, in another embodiment of the present invention, a baffle device 6 is provided at the annular tube 51. The baffle device 6 includes four side plates 61, which are respectively fixed on both sides of the annular tube 51 near the positioning component 2. A slide rod 62 is slidably installed through the outer side of each of the four side plates 61. A baffle 63 is fixed on the side of the slide rod 62 away from the side plate 61. A spring is provided between the baffle 63 and the side plate 61. An L-shaped inclined rod 64 is fixed on the side of each of the four baffles 63 near the positioning component 2, and the L-shaped inclined rod 64 is located on the side of the baffle 63 near the center of the annular tube 51 (e.g., Figure 12As shown in the diagram, the above structure allows the end face of the flat gate valve body to push the inclined surface of the L-shaped slant rod 64, which in turn moves the baffle 63 and the slide rod 62 toward the side plate 61. The baffle 63 can adapt to the diameter of the end face of the flat gate valve body to block the nozzles of the long nozzle 55 and the short nozzle 56 on the grinding plate 43, thereby ensuring that the grinding paste is only sprayed from the nozzles of the long nozzle 55 and the short nozzle 56 when the grinding area needs it, so that the grinding paste is only applied to the area that needs grinding and unnecessary waste is avoided.

[0038] In use, when the moving plate 32 approaches the flat gate valve body, the moving plate 32 drives the side plate 61 to move synchronously through the corrugated annular groove plate 47 and the annular tube 51. The side plate 61 drives the L-shaped inclined rod 64 to move along with it through the slide rod 62 and the baffle 63. When the inclined surface of the L-shaped inclined rod 64 moves to the end face of the flat gate valve body, the end face of the flat gate valve body pushes the inclined surface of the L-shaped inclined rod 64 to drive the baffle 63 and the slide rod 62 to move towards the side plate 61. The spring between the side plate 61 and the baffle 63 is compressed. The baffle 63 can adapt to the size of the diameter of the end face of the flat gate valve body to block the nozzles of the long nozzle 55 and the short nozzle 56 on the grinding plate 43, thereby ensuring that the nozzles of the long nozzle 55 and the short nozzle 56 spray the grinding paste only when the grinding area needs it, so that the grinding paste is only applied to the area that needs grinding and avoids unnecessary waste.

[0039] It should be noted that the obstruction formed by the baffle 63 on the nozzles of the long nozzle 55 and the short nozzle 56 creates a certain resistance to the spraying of the polishing paste. This resistance helps control the amount of polishing paste sprayed, ensuring that only a small amount is sprayed. Precise control of the spray helps ensure that the amount of polishing paste is moderate during the polishing process, avoiding waste and uneven polishing caused by excessive spraying. Since the obstruction effect only creates resistance on some nozzles, the unobstructed nozzles of the long nozzle 55 and the short nozzle 56 can spray the polishing paste in a concentrated manner. This ensures that the polishing paste is accurately concentrated and sprayed onto the target area. The obstruction by the baffle 63 can prevent the nozzles from spraying too much polishing paste, ensuring that enough polishing paste is provided when needed, reducing the situation of excessive spraying. This reduces polishing paste waste and makes the polishing process more stable and efficient.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
