Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically to a continuous machining equipment for a plug valve sealing assembly. Background Technology

[0002] A plug valve is a type of valve that controls fluid flow by rotating a plug. Plug valves are widely used in petroleum, chemical, and pharmaceutical industries. A plug valve is a plunger-shaped rotary valve consisting of a valve core, valve body, and valve seat. The valve core is cylindrical; rotating it 90 degrees opens or closes the valve by connecting or disconnecting the passage on the valve core with the passage on the valve body. The sealing components of a plug valve mainly include the valve core, valve seat, and thrust gasket. The valve seat is one of the most important components of a plug valve, and machining the flange on top of the valve seat is an essential step.

[0003] For example, Chinese Patent Publication No. CN107443083B describes an automatic processing equipment for a multi-station solenoid valve body. This equipment includes a processing table with a turntable at its center. Around the turntable, arranged sequentially along the rotation direction of the turntable, are a feeding device, a drilling device for two diagonally opposite holes on the front side of the valve body, a tapping device for two diagonally opposite holes on the front side of the valve body, a single-hole drilling device for the upper left corner of the front side of the valve body, a drilling device for two diagonally opposite holes on the rear side of the valve body, a tapping device for two diagonally opposite holes on the rear side of the valve body, a single-hole drilling device for the lower right corner of the rear side of the valve body, a drilling device for two holes on the top of the valve body, and a drilling device for cross-holes on the left side of the right side of the valve body. The valve body is equipped with a cross-hole drilling device on the right side of the valve body, a two-hole drilling device on the right side of the valve body at two diagonal angles, a two-hole drilling device on the left side of the valve body at two diagonal angles, a single-hole milling device on the upper left corner of the left side of the valve body, a single-hole milling device on the upper right corner of the left side of the valve body, a chamfering device on the left side of the valve body at two diagonal angles, and a feeding device. The processing ends of the above fourteen devices, except for the feeding and feeding devices, are all set towards the turntable. The turntable is equipped with several rotating positioning devices distributed circumferentially. Through the cooperation of the turntable and multiple devices, continuous automatic operation of multi-faceted valve body processing is realized, which greatly improves processing efficiency and reduces equipment and labor costs.

[0004] The valve seat is integrally cast. The flange on the top of the valve seat needs to be drilled. According to existing technical references, drilling can be performed by a drilling device, and multiple valve bodies can be continuously processed by rotating in multiple stations. However, this method involves continuously processing multiple blanks in a single process, which is inconvenient for continuous processing of multiple processes. The valve body needs to be transferred to the equipment. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention is implemented through the following technical solution: A continuous processing apparatus for a plug valve sealing assembly, comprising: The machine body, and a first bracket fixedly installed on the side of the machine body surface, a second bracket fixedly installed on the side of the machine body away from the first bracket, and a conveying mechanism installed between the first bracket and the second bracket; A continuous machining mechanism includes a gantry frame, which is fixedly installed at the midpoint between the bottom of the gantry frame and the top of the machine body. A drilling assembly and a grinding assembly are sequentially installed on the top of the gantry frame. The gantry frame supports the drilling assembly and the grinding assembly, making the overall drilling assembly and the grinding assembly more stable. The drilling assembly can be used to drill holes in the top connecting flange of the valve seat of the plug valve sealing assembly. After the drilling of the top connecting flange of the valve seat is completed, the grinding assembly grinds the top connecting flange of the valve seat, realizing continuous machining without transferring the valve seat to another machine tool. The drilling assembly includes a first hydraulic cylinder and a connector. The first hydraulic cylinder is fixedly installed on the side of the top of the gantry frame, and the connector is fixedly installed on the telescopic end of the first hydraulic cylinder. A drill bit is rotatably mounted on the bottom of the connector. A first bending rod is fixedly installed on the side of the connector surface, and a servo motor is fixedly installed in the middle of the top of the connector. By extending the telescopic end of the first hydraulic cylinder, a downward pushing force can be applied to the connector, which drives the drill bit to move downward. Adjusting the height of the drill bit helps to drill the flange on the top of the valve seat. By using four drill bits evenly distributed at the bottom of the connector, the flange on the top of the valve seat can be drilled in one go without adjusting the work position. The grinding assembly includes a second hydraulic cylinder and a triangular plate. The second hydraulic cylinder is fixedly installed on the top of the gantry frame and on the side away from the first hydraulic cylinder. The top of the surface of the triangular plate is fixedly installed with the telescopic end of the second hydraulic cylinder. A support roller is rolled on the top of the surface of the triangular plate, and a drive roller is rolled on the bottom of the surface of the triangular plate. A stepper motor is fixedly installed on the surface of the triangular plate near the drive roller. A grinding belt is installed between the support roller and the drive roller. A second bending rod is fixedly installed on the side of the surface of the triangular plate. By rotating the output end of the stepper motor, the drive roller can be driven to rotate, and under the rolling support of the support roller, the grinding belt will run, and the second hydraulic cylinder will be activated. By extending the telescopic end of the second hydraulic cylinder, a downward pushing force can be applied to the triangular plate, which will drive the grinding belt to move downward. With the operation of the grinding belt, the top of the drilled valve seat can be ground. The grinding belt is flexible, so that the grinding belt and the top of the valve seat make flexible contact, avoiding rigid contact, protecting the valve seat and preventing damage.

[0006] Preferably, the first and second brackets are installed symmetrically along the machine body, and the opening of the gantry is facing downwards.

[0007] Preferably, there are four drill bits, which are evenly distributed at the bottom of the connector. The top of each drill bit is connected to the output end of the servo motor via a gear assembly. There are two first bending rods, which are symmetrically installed along the connector.

[0008] Preferably, the end of the drive roller surface is fixedly installed to the output end of the stepper motor via a coupling, and there are two second bending rods, which are symmetrically installed along the grinding belt.

[0009] Preferably, the conveying mechanism includes a driving roller and a driven roller. The driving roller is rotatably mounted on the top of a first support, and the driven roller is rotatably mounted on the top of a second support. A driver is fixedly mounted on the surface of the first support near the driving roller. The end of the surface of the driving roller is fixedly mounted to the output end of the driver via a coupling. A conveyor belt is installed between the driving roller and the driven roller. A right-angle base is fixedly connected to the side of the surface of the conveyor belt. An arc-shaped limiting groove is opened on the top of the right-angle base. A rectangular limiting frame is fixedly connected to the surface of the right-angle base. The valve seat blank to be processed is placed on the right-angle base on the surface of the conveyor belt by an external robotic arm. The valve seat blank is limited by the bottom of the inlet flange and outlet flange at both ends of the valve seat blank being embedded in the arc-shaped limiting groove, so that the valve seat blank is not prone to skewing.

[0010] Preferably, the driving roller and the driven roller are installed at the same height, and the right-angle bases are evenly distributed on the sides of the conveyor belt surface.

[0011] Preferably, an auxiliary mechanism is installed on the top of the machine body and near the inner side of the gantry frame. The auxiliary mechanism includes a support plate, which is fixedly installed on the side of the top of the machine body. A support rod is fixedly installed in the middle of the surface of the support plate. A cylinder is rolled on the outer surface of the support rod away from the support plate. A centering component is installed on the top of the support plate. By utilizing the contact between the top of the outer surface of the cylinder and the top of the inner wall of the conveyor belt, the cylinder rolls as the conveyor belt rotates and is supported by the support rod. The rolling friction makes the conveyor belt smoothly transport the valve seat blank, and it is not easy to get stuck. Under the support of the cylinder, the conveyor belt and the valve seat blank will not sink downward, which helps to process and transport the valve seat blank.

[0012] Preferably, there are two support plates, and the two support plates are symmetrically installed along the central axis of the gantry frame, and the support rods are evenly distributed in the middle of the surface of the support plates.

[0013] Preferably, the centering assembly includes a strip guide rail, the bottom of which is fixedly installed between the bottom of the strip guide rail and the top of the support plate. An I-shaped block is slidably installed inside the strip guide rail. A centering cone is fixedly installed at one end of the I-shaped block away from the inner cavity of the strip guide rail via a right-angle plate. A reset spring is fixedly connected between the surface of the I-shaped block and the inner surface of the strip guide rail. A wedge block is fixedly connected to the top of the surface of the centering cone. A rod is fixedly connected to the edge of the surface of the centering cone, away from the wedge block. By using the first and second bending rods to move downwards, the side of the top of the centering cone is pushed by the inclined surface at the bottom of the bending rod. Under the sliding connection of the I-shaped block and guided by the strip guide rail, the two symmetrical centering cones on both sides move towards each other. The reset spring is squeezed and undergoes elastic deformation. The tips of the two symmetrical centering cones can then be inserted into the center of the inlet and outlet at both ends of the valve seat blank, thereby clamping and fixing the valve seat blank without deviation, ensuring accurate drilling and grinding.

[0014] Preferably, the surface of the I-shaped block is in contact with the inner side of the strip guide rail, and the reset spring is arc-shaped.

[0015] This invention provides a continuous processing apparatus for a plug valve sealing assembly. It has the following advantages: 1. The continuous processing equipment for the plug valve sealing assembly utilizes the extension of the telescopic end of the first hydraulic cylinder to apply a downward pushing force to the connector. The connector drives the drill bit to move downward, and the height of the drill bit is adjusted, which helps to drill the flange on the top of the valve seat. Furthermore, by using four drill bits evenly distributed at the bottom of the connector, the flange on the top of the valve seat can be drilled in one go without adjusting the work position.

[0016] 2. The continuous processing equipment for the plug valve sealing assembly places the valve seat blank to be processed on the right-angle base on the surface of the conveyor belt, and uses the bottom of the liquid inlet flange and the liquid outlet flange at both ends of the valve seat blank to embed into the arc-shaped limiting groove, and uses the bottom of the slide to be inside the rectangular limiting frame so that the rectangular limiting frame will not rotate or swing, thus limiting the valve seat blank.

[0017] Third, the continuous processing equipment for the plug valve sealing assembly, with the operation of the conveyor belt, causes the cylinder to roll, and the rolling friction makes the conveyor belt drive the valve seat blank smoothly and less prone to jamming. Under the support of the cylinder, the conveyor belt and the valve seat blank will not sink downward, which helps to process and transport the valve seat blank.

[0018] IV. The continuous processing equipment for the plug valve sealing assembly utilizes the downward movement of the first and second bending rods. The side of the top of the centering cone is pushed by the inclined surface at the bottom of the bending rod, causing the two symmetrical centering cones on both sides to move towards each other. The tips of the two symmetrical centering cones can then be inserted into the center of the inlet and outlet at both ends of the valve seat blank, thereby clamping and fixing the valve seat blank without any deviation, ensuring accurate drilling and grinding.

[0021] 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.

[0022] For the first embodiment, please refer to... Figure 1-5 The present invention provides a technical solution: A continuous processing apparatus for a plug valve sealing assembly, comprising: The machine body 1, and a first bracket 2 fixedly installed on the side of the surface of the machine body 1, a second bracket 3 fixedly installed on the side of the machine body 1 away from the first bracket 2, and a conveying mechanism 4 installed between the first bracket 2 and the second bracket 3. The continuous processing mechanism 5 includes a gantry frame 51, which is fixedly installed at the middle of the bottom of the gantry frame 51 and the top of the machine body 1. A drilling assembly 52 and a grinding assembly 53 are sequentially installed on the top of the gantry frame 51. The first bracket 2 and the second bracket 3 are installed symmetrically along the body 1, with the opening of the gantry 51 facing downwards.

[0023] The gantry frame 51 supports the drilling assembly 52 and the grinding assembly 53, making the overall structure of the drilling assembly 52 and the grinding assembly 53 more stable. The drilling assembly 52 can be used to drill the top connecting flange of the valve seat of the plug valve sealing assembly. After the drilling of the top connecting flange of the valve seat is completed, the grinding assembly 53 is used to grind the top connecting flange of the valve seat, realizing continuous processing without transferring the valve seat to another machine tool.

[0024] The drilling assembly 52 includes a first hydraulic cylinder 521 and a connector 522. The first hydraulic cylinder 521 is fixedly installed on the side of the top of the gantry frame 51. The connector 522 is fixedly installed on the telescopic end of the first hydraulic cylinder 521. A drill bit 523 is rotatably mounted on the bottom of the connector 522. A first bending rod 524 is fixedly installed on the side of the surface of the connector 522. A servo motor 525 is fixedly installed in the middle of the top of the connector 522. When the servo motor 525 is turned on, the drill bit 523 can be rotated by the rotation of the output end of the servo motor 525. The operator can also turn on the first hydraulic cylinder 521 to operate it, using the telescopic extension of the first hydraulic cylinder 521. The extension of the end can apply a downward pushing force to the connector 522, which drives the drill bit 523 to move downward. Adjusting the height of the drill bit 523 helps to drill the flange on the top of the valve seat. With four drill bits 523 evenly distributed at the bottom of the connector 522, the flange on the top of the valve seat can be drilled in one go without adjusting the position. After the valve seat is drilled, the retraction of the extension end of the first hydraulic cylinder 521 can apply an upward pulling force to the connector 522. The servo motor 525 and the drill bit 523 can then be driven upward through the connector 522, so that the drill bit 523 separates from the top of the valve seat, which facilitates the operation of the valve seat. There are four drill bits 523, which are evenly distributed at the bottom of the connector 522. The top of the drill bits 523 is connected to the output end of the servo motor 525 via a gear assembly. There are two first bending rods 524, which are symmetrically installed along the connector 522.

[0025] The grinding assembly 53 includes a second hydraulic cylinder 531 and a triangular plate 532. The second hydraulic cylinder 531 is fixedly installed on the top of the gantry frame 51 and on the side away from the first hydraulic cylinder 521. The top of the surface of the triangular plate 532 is fixedly installed with the telescopic end of the second hydraulic cylinder 531. A support roller 533 is rolled on the top of the surface of the triangular plate 532, and a drive roller 534 is rolled on the bottom of the surface of the triangular plate 532. A stepper motor 535 is fixedly installed on the surface of the triangular plate 532 near the drive roller 534. A grinding belt 536 is installed between the support roller 533 and the drive roller 534. A second bending rod 537 is fixedly installed on the side of the surface of the triangular plate 532. When the operator starts the stepper motor 535, the rotation of the output end of the stepper motor 535 drives the drive roller 534 to rotate, and the support roller 532 rotates on the side of the triangular plate 532. Under the rolling support of cylinder 3, the grinding belt 536 rotates, and the second hydraulic cylinder 531 is activated. By extending the telescopic end of the second hydraulic cylinder 531, a downward pushing force can be applied to the triangular plate 532. The triangular plate 532 will drive the grinding belt 536 to move downward. With the rotation of the grinding belt 536, the top of the drilled valve seat can be ground. The grinding belt 536 is flexible, so that the grinding belt 536 and the top of the valve seat are in flexible contact, avoiding rigid contact and protecting the valve seat from damage. After the top of the valve seat is ground, the telescopic end of the second hydraulic cylinder 531 retracts, which can apply an upward pulling force to the triangular plate 532. The triangular plate 532 can then drive the grinding belt 536 upward, so that the grinding belt 536 separates from the valve seat, making it easy to remove and unload the processed valve seat.

[0026] The end of the drive roller 534 is fixedly installed to the output end of the stepper motor 535 via a coupling. There are two second bending rods 537, and the two second bending rods 537 are symmetrically installed along the grinding belt 536.

[0027] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 6 As shown: The conveying mechanism 4 includes a driving roller 41 and a driven roller 42. The driving roller 41 is rotatably mounted on the top of the first support 2, and the driven roller 42 is rotatably mounted on the top of the second support 3. A driver 43 is fixedly mounted on the surface of the first support 2 near the driving roller 41. The end of the surface of the driving roller 41 is fixedly mounted to the output end of the driver 43 via a coupling. A conveyor belt 44 is installed between the driving roller 41 and the driven roller 42, and a straight... An angle base 45 has an arc-shaped limiting groove 46 on its top. A rectangular limiting frame 47 is fixedly connected to the surface of the right-angle base 45. The valve seat blank to be processed is placed on the right-angle base 45 on the surface of the conveyor belt 44. The bottom of the liquid inlet flange and the liquid outlet flange at both ends of the valve seat blank are embedded in the arc-shaped limiting groove 46. The bottom of the slide is located inside the rectangular limiting frame 47, so that the rectangular limiting frame 47 will not rotate or swing, thus limiting the valve seat blank.

[0028] The driving roller 41 and the driven roller 42 are installed at the same height, and the right-angle bases 45 are evenly distributed on the sides of the surface of the conveyor belt 44.

[0029] The third embodiment is based on the first and second embodiments; please refer to [link / reference]. Figures 1 to 8 As shown: An auxiliary mechanism 6 is installed on the top of the machine body 1 and near the inner side of the gantry 51. The auxiliary mechanism 6 includes a support plate 61, which is fixedly installed on the side of the top of the machine body 1. A support rod 62 is fixedly installed in the middle of the surface of the support plate 61. A cylinder 63 is rolled on the outer circular surface of the support rod 62 and at the end away from the support plate 61. A centering component 64 is installed on the top of the support plate 61.

[0030] The operator starts the driver 43. The rotation of the output end of the driver 43 drives the active roller 41 to roll. With the support of the driven roller 42, the conveyor belt 44 runs. The valve seat blank is supported by the right-angle base 45 and transported. The valve seat blank moves towards the bottom of the drill bit 523 for processing. The top of the outer surface of the cylinder 63 fits against the top of the inner wall of the conveyor belt 44. As the conveyor belt 44 runs and is supported by the support rod 62, the cylinder 63 rolls. The rolling friction makes the conveyor belt 44 transport the valve seat blank smoothly and prevents jamming. The support of the cylinder 63 prevents the conveyor belt 44 and the valve seat blank from sinking, which helps to process and transport the valve seat blank.

[0031] There are two support plates 61, and the two support plates 61 are symmetrically installed along the central axis of the gantry frame 51. The support rods 62 are evenly distributed in the middle of the surface of the support plate 61.

[0032] The centering assembly 64 includes a strip guide rail 641, with its bottom fixedly mounted to the top of the support plate 61. An I-shaped block 642 is slidably mounted inside the strip guide rail 641. A centering cone 643 is fixedly mounted on one end of the I-shaped block 642 away from the inner cavity of the strip guide rail 641 via a right-angle plate. A reset spring 644 is fixedly connected between the surface of the I-shaped block 642 and the inner surface of the strip guide rail 641. A wedge is fixedly connected to the top of the surface of the centering cone 643. A wedge 646 is fixedly connected to the edge of the centering cone 643 surface of the wedge 645, on the side away from the wedge 645. The valve seat blank is machined using the drilling assembly 52 and the grinding assembly 53. The extension of the telescopic end of the first hydraulic cylinder 521 causes the connector 522 to move downwards, resulting in the first bent rod 524 moving downwards along with the connector 522. Furthermore, the extension of the telescopic end of the second hydraulic cylinder 531 causes the triangular plate 532 to move downwards, resulting in the second bent rod 537 moving downwards along with the triangular plate 532. As the angle plate 532 moves downward, the first bending rod 524 and the second bending rod 537 can also move downward. The top edge of the centering cone 643 is pushed by the inclined surface at the bottom of the bending rod. Under the sliding connection of the I-shaped block 642 and guided by the strip guide rail 641, the two symmetrical centering cones 643 move towards each other, and the reset spring 644 is compressed and elastically deformed. The tips of the two symmetrical centering cones 643 can then be inserted into the valve seat blank. The valve seat blank is clamped and fixed at the center of the inlet and outlet of the valve seat, preventing displacement and ensuring accurate drilling and grinding. As the first bending rod 524 and the second bending rod 537 move upward, the pushing force on the centering cone 643 disappears. Under the elastic force of the reset spring 644, the I-shaped block 642 drives the centering cone 643 to move in the opposite direction to reset. The centering cone 643 moves away from the valve seat, releasing the valve seat and facilitating its removal.

[0033] The surface of the I-shaped block 642 fits against the inner side of the strip guide rail 641, and the reset spring 644 is arc-shaped.

[0034] In use, the valve seat blank to be processed is first placed on the right-angle base 45 on the surface of the conveyor belt 44 by an external robotic arm. The bottom of the inlet flange and outlet flange at both ends of the valve seat blank are embedded in the arc-shaped limiting groove 46. The bottom of the slide is located inside the rectangular limiting frame 47, so that the rectangular limiting frame 47 will not rotate or swing, thus limiting the valve seat blank. At this time, the operator starts the driver 43 to work. By rotating the output end of the driver 43, the active roller 41 can be driven to roll. Under the rolling support of the driven roller 42, the conveyor belt 44 can run. The valve seat blank can be transported by the support of the right-angle base 45. The valve seat blank moves to the bottom position of the drill bit 523. When the valve seat blank moves directly below the drill bit 523, the operation of the driver 43 can be paused, thus stopping the movement of the valve seat blank. The top of the outer surface of the cylinder 63 is in contact with the top of the inner wall of the conveyor belt 44. As the conveyor belt 44 rotates and is supported by the support rod 62, the cylinder 63 rolls. The rolling friction makes the conveyor belt 44 carry the valve seat blank smoothly and is less likely to jam. Under the support of the cylinder 63, the conveyor belt 44 and the valve seat blank will not sink downward. Simultaneously, the servo motor 525 is activated. The rotation of the output of the servo motor 525 drives the drill bit 523 to rotate. The operator also activates the first hydraulic cylinder 521. The extension of the telescopic end of the first hydraulic cylinder 521 applies a downward pushing force to the connector 522, causing the drill bit 523 to move downwards. The first bending rod 524 moves downwards along with the connector 522. This downward movement of the first bending rod 524 causes the edge of the centering cone 643 to be pushed by the inclined surface of the bottom of the bending rod 537. The groove on the inclined surface of the bending rod 537 engages with the wedge block 645, ensuring a reliable connection between the centering cone 643 and the bending rod 537. This connection is further facilitated by the sliding connection of the I-beam block 642. Next, guided by the strip guide rail 641, the two symmetrical centering cones 643 move towards each other, and the reset spring 644 is compressed and deformed elastically. The tips of the two symmetrical centering cones 643 can be inserted into the center of the inlet and outlet at both ends of the valve seat blank. At the same time, the insert rods 646 evenly distributed on the surface of the centering cones 643 can be inserted into the inlet flange holes and outlet flange holes at both ends of the valve seat blank, thereby clamping and fixing the valve seat blank without deviation. By adjusting the height of the drill bit 523, it is helpful to drill the flange on the top of the valve seat. With the four drill bits 523 evenly distributed at the bottom of the connector 522, the flange on the top of the valve seat can be drilled in one go without adjusting the position. After the valve seat is drilled, the retraction of the telescopic end of the first hydraulic cylinder 521 can apply an upward pulling force to the connector 522, which can then drive the servo motor 525 and the drill bit 523 to move upward, so that the drill bit 523 separates from the top of the valve seat. As the pushing force of the bending rod 537 on the centering cone 643 disappears, and under the elastic force of the reset spring 644, the sliding of the I-shaped block 642 drives the centering cone 643 to move in the opposite direction, and the centering cone 643 releases the fixation of the liquid inlet and liquid outlet at both ends of the valve seat blank. Then, the driver 43 is turned on again. The rotation of the output end of the driver 43 can cause the conveyor belt 44 to move the valve seat blank after drilling. When the valve seat blank moves directly under the grinding belt 536, the driver 43 can be paused again to stop the movement of the valve seat blank. As the extension end of the second hydraulic cylinder 531 extends, the triangular plate 532 moves downward, causing the second bending rod 537 to move downward along with the triangular plate 532. The second bending rod 537 applies a pushing force to the centering cone 643, which can fix the valve seat blank directly below the grinding belt 536. At this time, the operator starts the stepper motor 535. The rotation of the output end of the stepper motor 535 drives the drive roller 534 to rotate. Under the rolling support of the support roller 533, the grinding belt 536 runs. The second hydraulic cylinder 531 is activated. The extension of the telescopic end of the second hydraulic cylinder 531 applies a downward pushing force to the triangular plate 532. The triangular plate 532 drives the grinding belt 536 to move downward. With the operation of the grinding belt 536, the top of the drilled valve seat can be ground. The grinding belt 536 is flexible, so that the grinding belt 536 and the top of the valve seat are in flexible contact, avoiding rigid contact and protecting the valve seat from damage. After the top of the valve seat is ground, the retraction of the telescopic end of the second hydraulic cylinder 531 applies an upward pulling force to the triangular plate 532. The triangular plate 532 drives the grinding belt 536 to move upward, so that the grinding belt 536 separates from the valve seat. Once the valve seat is processed, it can be transported out via conveyor belt 44 and removed and unloaded by an external robotic arm.
