Description

Technical Field

[0001] This invention relates to the field of automated ball valve assembly technology, specifically to a ball valve sealing component press-fitting device. Background Technology

[0002] As a core opening and closing component widely used in petroleum, chemical, water treatment and household fluid control fields, the sealing performance of ball valves directly determines the service life of valves and system safety. The sealing element (sealing ring) needs to be precisely pressed into the annular sealing groove inside the valve body to ensure the sealing performance of the valve ball.

[0003] Currently, in the actual assembly and production of ball valve seals, most small and medium-sized manufacturing enterprises, and even some large manufacturers' outdated production lines, still rely mainly on manual hand-held tools to complete the press-fitting of seals. Operators need to manually pre-insert the seal into the valve body opening, and then use a pressure bar, hammer, or simple manual press to press it down one by one. This traditional manual assembly method requires multiple manual operations such as "removing the valve body - removing the seal - manually placing - applying pressure" for the press-fitting of a single seal. The time taken for a single piece is usually several seconds to more than ten seconds. Moreover, after long periods of repetitive labor, the physical strength of the operators decreases, further slowing down the operation speed. For large-volume production orders, the manual assembly speed is far from meeting the production capacity requirements, often becoming a bottleneck process in the entire ball valve assembly line, seriously restricting the output capacity of enterprises. Summary of the Invention

[0004] In view of the above-mentioned shortcomings in the existing technology, the purpose of this invention is to provide a ball valve seal press-fitting equipment that can accelerate production efficiency.

[0005] The technical solution adopted by the present invention to achieve the above-mentioned objective is as follows: a ball valve sealing component pressing device, comprising a valve body feeding mechanism, a sealing component feeding mechanism, and a pressing mechanism. The valve body feeding mechanism includes a material tray for feeding the valve body. The sealing component feeding mechanism is provided on one side of the valve body feeding mechanism. The sealing component feeding mechanism includes a material groove for feeding the sealing component. The material groove is located on one side of a group of valve bodies on the material tray. The material groove has a discharge port on the side near the valve body. A push port is provided on the material groove corresponding to the discharge port. A feeding mechanism is provided on the material groove in conjunction with the discharge port and the push port. The feeding mechanism is used to push the sealing component located at the end of the material groove from the discharge port into the interior of the valve body. The pressing mechanism is provided on one side of the valve body feeding mechanism. The pressing mechanism includes a pressure plug that can move linearly up and down. The pressure plug corresponds to the middle part of the valve body adjacent to the material groove.

[0006] The pressing mechanism is implemented using the following structure:

[0007] The pressing mechanism further includes a lifting module, which includes a lifting platform capable of linear lifting motion, and the pressing plug is fixedly connected to the lifting platform.

[0008] The feeding mechanism includes a pusher platform and a drive module for pulling the pusher platform to move linearly, and the pusher platform is slidably connected in the pusher port;

[0009] The drive module and the lifting platform are poweredly connected through a transmission system. When the lifting platform descends, the drive module pulls the pusher platform toward the discharge port. When the lifting platform rises, the drive module pulls the pusher platform toward the discharge port.

[0010] The specific structure of the valve body feeding mechanism is as follows:

[0011] The valve body feeding mechanism also includes a first motor, a base, and a positioning sleeve. The material tray is rotatably connected to the base. The base has a power chamber inside. A drive shaft is fixedly connected to the center of the material tray. The first motor is fixedly connected inside the power chamber. The first motor is poweredly connected to the drive shaft.

[0012] The material tray has multiple sets of positioning sleeves fixedly connected in a circular array. The positioning sleeves are used to place the valve body and achieve positioning.

[0013] Furthermore, the sealing component feeding mechanism also includes a feeding device, which cooperates with the material trough;

[0014] The feeding device is a vibratory feeder automatic feeder.

[0015] The pressing mechanism further includes a frame on which the lifting module is mounted;

[0016] Specifically, the lifting module further includes a transmission screw, a second motor, and a guide column. The guide column is fixedly connected to the frame, and the lifting platform is slidably connected to the guide column. A screw sleeve is fixedly connected to the lifting platform, and the transmission screw is threaded onto the screw sleeve. The second motor is fixedly connected to the frame, and the second motor is poweredly connected to the transmission screw.

[0017] The drive module can be implemented using the following structure:

[0018] The drive module includes a rotating disk, a traction arm, and a push-pull arm. A mounting frame is fixedly connected to the material trough. The rotating disk is rotatably connected to the mounting frame via a rotating shaft. An eccentric shaft is fixedly connected to the rotating disk. One end of the traction arm is rotatably connected to the eccentric shaft. The push-pull arm is fixedly connected to the material pusher. The other end of the traction arm is rotatably connected to the push-pull arm.

[0019] The rotating shaft is poweredly connected to the lifting platform through the transmission system.

[0020] The transmission system can be implemented using the following structure:

[0021] The transmission system includes a first bevel gear, a second bevel gear, a transmission shaft, a transmission gear, and a drive rack. The first bevel gear is fixedly connected to the rotating shaft, the transmission shaft is rotatably connected to the mounting bracket, the second bevel gear is fixedly connected to the transmission shaft, the first bevel gear and the second bevel gear mesh with each other, the transmission gear is fixedly connected to the transmission shaft, and the drive rack is fixedly connected to the lifting platform via a connecting bracket, the drive rack cooperating with the transmission gear.

[0022] Furthermore, to improve the rotational stability of the material tray, a rotating ring is fixedly connected to the bottom of the material tray, and a rotating groove is provided on the base corresponding to the rotating ring, with the rotating ring rotatably connected in the rotating groove.

[0023] Furthermore, a feeding system is provided on one side of the pressing mechanism, which is used to unload the valve body with the assembled seal from the material tray;

[0024] The unloading system is provided with a loading system on one side, which is used to load valve bodies without seals onto the material tray.

[0025] Specifically, both the feeding system and the unloading system include a multi-axis motion gripping module and a conveyor belt device that works in conjunction with the multi-axis motion gripping module;

[0026] The multi-axis motion clamping module includes a module frame, an X-axis motion table, an X-axis lead screw, and a third motor. An X-axis guide rail is fixedly connected to the module frame, and the X-axis motion table is slidably connected to the X-axis guide rail. The X-axis lead screw is threaded onto the X-axis motion table, and the third motor is fixedly connected to the module frame. The third motor is poweredly connected to the X-axis lead screw.

[0027] A longitudinal frame is fixedly connected to the X-axis motion table, a Z-axis guide rail is fixedly connected to the longitudinal frame, a Z-axis motion table is slidably connected to the Z-axis guide rail, a Z-axis lead screw is threaded onto the Z-axis motion table, a fourth motor is fixedly connected to the longitudinal frame, and the fourth motor is poweredly connected to the Z-axis lead screw.

[0028] The Z-axis motion platform is fixedly connected to a gripper via a mounting arm.

[0029] The beneficial effects of this invention are:

[0030] 1. The valve body can be transported to the assembly station by the valve body feeding mechanism, while the seal feeding mechanism can gradually transport the seal into the material trough. The unloading mechanism pushes the seal out of the material trough from the unloading port, so that the seal enters the valve cavity of the valve body. Then, the pressure plug descends, so that the pressure plug presses the seal into the valve body. This structure can realize automated pressing work, reduce manpower, and speed up production efficiency.

[0031] 2. By connecting the lifting platform in the pressing mechanism with the drive module in the unloading mechanism through a transmission system, the mechanical linkage between the lifting motion of the press plug and the reciprocating linear motion of the pusher is achieved. When the lifting platform descends to perform pressing, the drive module synchronously pulls the pusher towards the unloading port of the material trough, pushing the seal into the valve body. When the lifting platform rises to reset, the pusher reverses and retracts to the unloading port to make way for the next seal. This structure eliminates the need for a separate power source and control system for the unloading mechanism, which not only reduces equipment manufacturing costs and control complexity, but also fundamentally ensures the absolute synchronization and positional accuracy of the two key actions of pressing and feeding in terms of timing. This avoids faults such as pressure leakage and repeated feeding caused by electrical signal delays or false triggering, and significantly improves the pressing cycle time and product consistency.

[0032] 3. The valve body feeding mechanism uses a first motor to drive the material tray to rotate intermittently on the base. Multiple sets of positioning sleeves are fixedly connected in a ring array on the material tray. Each set of positioning sleeves can accurately position a single valve body. This ensures that every time the material tray rotates one station, a new valve body accurately reaches the pressing position corresponding to the pressure plug and the material groove outlet. This structure realizes the orderly and continuous supply of valve bodies. It works closely with the rhythmic lifting motion of the pressing mechanism and the intermittent feeding of the sealing components to form an efficient assembly line operation mode. This greatly improves the pressing efficiency in mass production scenarios. At the same time, the setting of the positioning sleeves ensures the repeatability of the position of each valve body during the pressing process, thereby ensuring the uniformity of the pressing depth of the sealing components and the sealing effect.

[0033] 4. The transmission system adopts a combination of a first bevel gear, a second bevel gear, a transmission shaft, a transmission gear, and a drive rack to convert the vertical linear motion of the lifting platform into the rotational motion of the rotating disk, and then into the linear motion of the pushing platform through the traction arm and the push-pull arm. This purely mechanical transmission structure is simple, has few parts, and all of them adopt standard gear and rack meshing transmission, which has extremely high transmission efficiency and impact resistance. It can operate stably for a long time in dusty or oily environments, significantly reducing the equipment failure rate and subsequent maintenance costs. Attached Figure Description

[0051] 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.

[0052] Please see Figures 1-11 The present invention provides a ball valve sealing component press-fitting device, which is used to realize the automated press-fitting assembly of ball valve body and sealing component. In terms of spatial layout, the device is centered on the valve body feeding mechanism 100, the sealing component feeding mechanism 200 is set on one side of the valve body feeding mechanism 100, the press-fitting mechanism 300 is set on the other side or adjacent side of the valve body feeding mechanism 100, and the loading system 400 and unloading system 500 are respectively arranged at the upstream and downstream workstations of the valve body feeding mechanism 100, thereby forming a complete automated production line from valve body loading, sealing component feeding and press-fitting, and finished product unloading.

[0053] First of all, please refer to Figure 5 The valve body feeding mechanism 100 includes a material tray 101, a first motor 102, a base 103, and a positioning sleeve 104. The base 103 is a fixed support component located in the central area of ​​the equipment. The base 103 has a power chamber 105, which is a hollow structure inside the base 103. The material tray 101 is rotatably connected to the top of the base 103. A drive shaft is fixedly connected to the center of the material tray 101. The drive shaft is vertically positioned and extends downwards into the power chamber 105 of the base 103. The first motor 102 is fixedly connected within the power chamber 105. The output shaft of the first motor 102 is connected to the drive shaft via a coupling or gear pair. When the motor 102 starts, it drives the material tray 101 to rotate intermittently on the base 103 via the drive shaft. Multiple sets of positioning sleeves 104 are fixedly connected in a ring array on the upper surface of the material tray 101. Each set of positioning sleeves 104 has an inner hole that matches the outer circumferential shape of the valve body. After the valve body is placed into the positioning sleeve 104 from above, the positioning sleeve 104 limits its radial and axial position, ensuring that the position of each valve body on the material tray 101 is highly consistent. Multiple sets of positioning sleeves 104 are evenly distributed along the circumference of the material tray 101, so that every time the material tray 101 rotates by a fixed indexing angle, a set of positioning sleeves 104 carries a valve body from the previous station to the next station.

[0054] To further improve the stability of the material tray 101 under heavy load, a rotating ring 106 is fixedly connected to the bottom of the material tray 101. The rotating ring 106 has a circular structure and is coaxially arranged with the material tray 101. At the same time, a rotating groove 107 is opened at the corresponding position on the upper surface of the base 103. The rotating ring 106 is embedded in the rotating groove 107 and can slide or roll in the rotating groove 107, thereby providing additional annular support and guidance on the periphery of the material tray 101, effectively preventing the material tray 101 from tilting or becoming eccentric after long-term intermittent rotation.

[0055] Secondly, please refer to Figure 1 , Figures 6-8 The sealing component feeding mechanism 200 is located on the side of the material tray 101. It is used to supply sealing components to the valve body in the pressing position. The sealing component feeding mechanism 200 includes a material trough 201, a feeding device 202 and a discharging mechanism 203. The feeding device 202 adopts a vibratory feeder. The vibratory feeder is located at the inlet end of the material trough 201. It uses vibration to arrange the randomly stacked sealing components in a uniform posture and feed them into the material trough 201 in sequence. The material trough 201 is a long strip channel component. The cross-sectional shape of its internal channel is adapted to the shape of the sealing component. The sealing components are arranged closely in sequence along the length direction in the material trough 201 and can slide forward.

[0056] A discharge port 204 is provided on the side of the material trough 201 near the valve body. The size of the discharge port 204 is not less than the outer dimensions of a single seal, so that the seal can be moved laterally out of the material trough 201 from the discharge port 204 and into the internal opening of the valve body. A push port 205 is also provided on the material trough 201 at the position corresponding to the discharge port 204. The push port 205 is located on the side of the material trough 201 opposite to the discharge port 204.

[0057] Furthermore, the unloading mechanism 203 includes a pusher platform 206 and a drive module 207. The pusher platform 206 is slidably connected to the push port 205. The front end of the pusher platform 206 is a pusher end, which can extend into the material groove 201 and directly push the seal located at the end of the material groove 201. The sliding direction of the pusher platform 206 is towards the unloading port 204. When the pusher platform 206 slides towards the unloading port 204, the pusher end pushes the seal out of the unloading port 204.

[0058] When the pusher table 206 slides away from the discharge port 204, the pusher end retracts from the inside of the trough 201;

[0059] The drive module 207 is used to pull the pusher table 206 to perform reciprocating linear motion within the pusher port 205. Specifically, it includes a rotating disk 208, a traction arm 209, and a push-pull arm 210. A mounting frame is fixedly connected to the outer wall of the material trough 201. The rotating disk 208 is rotatably connected to the mounting frame via a rotating shaft. The rotating disk 208 can rotate freely around the axis of the rotating shaft. An eccentric shaft 211 is fixedly connected to the rotating disk 208 at a position off the axis of the rotating shaft. The eccentric shaft 211 moves in a circular motion together with the rotating disk 208. The pusher table 206 is fixedly connected to the pusher table 206. The push-pull arm 210 extends outward from the pusher table 206. One end of the traction arm 209 is rotatably connected to the eccentric shaft 211, and the other end of the traction arm 209 is rotatably connected to the push-pull arm 210, thereby converting the rotational motion of the rotating disk 208 into the reciprocating linear motion of the pusher table 206.

[0060] Furthermore, the pressing mechanism 300 is located on the other side of the material tray 101 and is adjacent to or opposite to the sealing element feeding mechanism 200. It is used to vertically press the sealing element that has been fed into the valve body into the valve body. The pressing mechanism 300 includes a frame 301, a lifting module 302 and a pressure plug 303. The frame 301 is a fixed support frame that stands upright next to the base 103. The lifting module 302 is provided on the frame 301. The lifting module 302 includes a lifting platform 304, a transmission screw 305, a second motor 306 and a guide column 307. The guide column 307 is fixedly connected to the frame 301. The guide column 307 is a vertically arranged linear guide column. There are two of them and they are evenly distributed on both sides of the lifting platform 304. The lifting platform 304 is slidably connected to the guide column 307 through a guide hole or a linear bearing, and can make precise linear lifting and lowering movements in the vertical direction along the guide column 307.

[0061] A lead screw sleeve is fixedly connected to the lifting platform 304. The lead screw sleeve is a sleeve component with threads on the inner wall. The transmission lead screw 305 is vertically arranged and passes through the lead screw sleeve. The external thread of the transmission lead screw 305 meshes with the internal thread of the lead screw sleeve. A second motor 306 is fixedly connected to the frame 301. The output shaft of the second motor 306 is connected to the transmission lead screw 305 through a coupling or pulley. When the second motor 306 rotates forward or in reverse, it drives the transmission lead screw 305 to rotate. With the help of the transmission principle of the lead screw and nut pair, the lifting platform 304 is driven to rise or fall along the guide column 307.

[0062] The pressure plug 303 is fixedly connected to the lifting platform 304. The pressure plug 303 is a columnar component whose lower end shape is adapted to the sealing element and the inner cavity of the valve body. Its vertical center line coincides with the center line of the group of valve bodies located at the pressing station. The pressure plug 303 rises and falls synchronously with the lifting platform 304. When it descends, it enters the valve body and presses the sealing element into the predetermined position.

[0063] In further optimization, the drive module 207 and the lifting platform 304 are connected by a transmission system 600, so that the lifting movement of the lifting platform 304 can synchronously drive the rotating disk 208 to rotate, thereby controlling the forward and backward movement of the pusher platform 206.

[0064] Specifically, please refer to Figure 10 The transmission system 600 includes a first bevel gear 601, a second bevel gear 602, a transmission shaft 603, a transmission gear 604, and a drive rack 605. Specifically, the first bevel gear 601 is fixedly connected to the rotating shaft and is coaxial with the rotating shaft. The transmission shaft 603 is also rotatably connected to the mounting bracket. The transmission shaft 603 is horizontally arranged on the mounting bracket, and its axis is perpendicular to the axis of the rotating shaft. The second bevel gear 602 is fixedly connected to the transmission shaft 603. The first bevel gear 601 and the second bevel gear 602 mesh with each other to form a bevel gear transmission pair. The transmission gear 604 is also fixedly connected to the transmission shaft 603 and is coaxial with the transmission shaft 603.

[0065] A drive rack 605 is fixedly connected to the lifting platform 304 via a connecting frame. The connecting frame is an extension component that extends laterally from the lifting platform 304. The drive rack 605 is fixedly installed at the end of the connecting frame. The length direction of the drive rack 605 is vertical, and the tooth surface of the drive rack 605 meshes with the tooth surface of the transmission gear 604.

[0066] When the lifting platform 304 descends, the drive rack 605 moves down with the lifting platform 304, driving the transmission gear 604 to rotate in the first direction. Through the sequential transmission of the transmission shaft 603, the second bevel gear 602 and the first bevel gear 601, the rotating disk 208 is driven to rotate in the corresponding direction. The eccentric shaft 211 on the rotating disk 208 pulls the pusher table 206 to move towards the lower material port 204 through the traction arm 209 and the push-pull arm 210, that is, the pusher table 206 performs the pushing action.

[0067] When the lifting platform 304 rises, the drive rack 605 moves up with the lifting platform 304, and the drive transmission gear 604 rotates in the opposite direction. The transmission system 600 transmits power in the opposite direction, the rotating disk 208 rotates in the opposite direction, and the eccentric shaft 211 pulls the pusher table 206 back towards the push port 205 through the traction arm 209 and the push-pull arm 210. That is, the pusher table 206 performs a reset action.

[0068] This achieves synchronous linkage between the descent of the pressure plug 303 and the ejection of the seal, as well as synchronous linkage between the rise of the pressure plug 303 and the reset of the pusher table 206.

[0069] Finally, the feeding system 400 and the unloading system 500 are respectively located upstream and downstream of the valve body feeding mechanism 100. The feeding system 400 is used to grab the valve body without the seal from the external conveyor line and place it into the positioning sleeve 104 on the material tray 101.

[0070] The unloading system 500 is used to remove the valve body with assembled seals from the positioning sleeve 104 and transport it to the next process;

[0071] The feeding system 400 and the unloading system 500 both adopt the same structure, each including a multi-axis motion clamping module 401 and a conveyor belt device 402 that cooperates with the multi-axis motion clamping module 401. The conveyor belt device 402 is a conventional belt conveyor or chain plate conveyor, which is set on the side of the feeding station and the unloading station respectively, and is used to carry and transport the valve body to be assembled or the valve body that has been assembled.

[0072] In this implementation, please refer to Figure 11 The multi-axis motion gripping module 401 includes a module frame 403, an X-axis motion table 404, an X-axis lead screw 405, a third motor 406, a longitudinal frame 407, a Z-axis motion table 408, a Z-axis lead screw 409, a fourth motor 410, a mounting arm, and grippers 411. Specifically, the module frame 403 is a fixed support frame, and an X-axis guide rail is fixedly connected to the module frame 403. The X-axis guide rail is a horizontally arranged linear guide rail, and the X-axis motion table 404 is slidably connected... Attached to the X-axis guide rail, it can slide horizontally along the X-axis guide rail. The X-axis motion table 404 is threaded with an X-axis lead screw 405. The X-axis lead screw 405 is horizontally set on the module frame 403. A third motor 406 is fixedly connected to the module frame 403. The output shaft of the third motor 406 is poweredly connected to the X-axis lead screw 405. The third motor 406 drives the X-axis lead screw 405 to rotate, thereby driving the X-axis motion table 404 to move laterally along the X-axis guide rail.

[0073] A longitudinal frame 407 is fixedly connected to the X-axis motion table 404. The longitudinal frame 407 is a vertical support frame that moves laterally with the X-axis motion table 404. A Z-axis guide rail is fixedly connected to the longitudinal frame 407. The Z-axis guide rail is a vertically arranged linear guide rail. The Z-axis motion table 408 is slidably connected to the Z-axis guide rail and can slide vertically along the Z-axis guide rail. A Z-axis lead screw 409 is threaded onto the Z-axis motion table 408. The Z-axis lead screw 409 is vertically arranged on the longitudinal frame 407. A fourth motor 410 is fixedly connected to the longitudinal frame 407. The output shaft of the fourth motor 410 is poweredly connected to the Z-axis lead screw 409. The fourth motor 410 drives the Z-axis lead screw 409 to rotate, thereby driving the Z-axis motion table 408 to move vertically along the Z-axis guide rail.

[0074] A gripper 411 is fixedly connected to the Z-axis motion table 408 via a mounting arm. The mounting arm is a connecting member that extends horizontally from the Z-axis motion table 408. The gripper 411 is a pneumatically or electrically driven openable and closable clamping member used to grip or release the valve body.

[0075] Through the coordinated control of the third motor 406 and the fourth motor 410, the gripper 411 can achieve two-dimensional precise positioning in the horizontal and vertical directions, thereby completing the loading action of gripping the valve body from the conveyor belt device 402, moving it above the positioning sleeve 104 of the material tray 101, and lowering it to release the valve body, or the unloading action of gripping the finished valve body from the positioning sleeve 104, moving it above the unloading conveyor belt, and releasing the valve body.

[0076] The complete working process of the ball valve seal press-fitting equipment of the present invention during actual operation is as follows.

[0077] First, the valve body is loaded. The conveyor belt device 402 of the loading system 400 sequentially transports the unpressurized valve bodies to the loading clamping position. The third motor 406 of the loading system 400 starts, driving the X-axis lead screw 405 to rotate. The X-axis motion table 404 moves laterally along the X-axis guide rail, aligning the gripper 411 horizontally with the valve body at the loading position. Then, the fourth motor 410 starts, driving the Z-axis lead screw 409 to rotate. The Z-axis motion table 408 moves downward along the Z-axis guide rail, lowering the gripper 411 to a height suitable for clamping the valve body. The gripper 411 closes, grasping the valve body. The fourth motor 410 reverses, the Z-axis motion table 408 rises, lifting the valve body from the conveyor belt device 402. The third motor 406 starts again, the X-axis motion table 404 moves laterally to directly above an empty positioning sleeve 104 on the material tray 101. The fourth motor 410 rotates forward, the Z-axis motion table 408 descends, the gripper 411 opens, releasing the valve body into the positioning sleeve 104, completing the loading of one valve body. Among the multiple sets of positioning sleeves 104 on the material tray 101, some positioning sleeves 104 have been loaded and are carrying valve bodies, while some positioning sleeves 104 are empty and waiting to be replenished.

[0078] Subsequently, the material tray 101 is intermittently rotated for feeding. The first motor 102 is started and drives the material tray 101 to rotate on the base 103 by a division angle through the drive shaft. This causes a set of positioning sleeves 104, which already carries the valve body, to be transferred from the previous station to the pressing station. The pressing station is located next to the discharge port 204 of the sealing material feeding mechanism 200 and directly below the pressure plug 303 of the pressing mechanism 300. At this time, the middle opening of the valve body is sideways facing the discharge port 204 of the material groove 201, and the middle opening of the valve body is upward facing the lower end of the pressure plug 303.

[0079] While the material tray 101 is rotating and positioned, the sealing component feeding mechanism 200 is in standby mode. The vibratory feeder continues to work, feeding the sealing components into the material trough 201 in a uniform manner. The sealing components are closely arranged in the material trough 201, with the foremost sealing component located at the end of the material trough 201, its position directly facing the discharge port 204 and the push port 205.

[0080] Next, the pressing and pushing actions begin. The second motor 306 rotates forward, driving the transmission screw 305 to rotate. Through the threaded engagement of the screw sleeve, the lifting platform 304 moves downwards along the guide column 307. The pressure plug 303, fixedly connected to the lifting platform 304, descends synchronously. The lower end of the pressure plug 303 gradually approaches the central opening of the valve body. Simultaneously, as the lifting platform 304 descends, the drive rack 605, fixedly connected to the side connecting bracket of the lifting platform 304, moves downwards. The drive rack 605 drives the transmission gear 604, which meshes with it, to rotate. The rotation of the transmission gear 604 is transmitted to the second bevel gear 602 via the transmission shaft 603. The second bevel gear 602 then drives the... A bevel gear 601 rotates, which in turn drives the rotating shaft and rotating disk 208 to rotate. The eccentric shaft 211 on the rotating disk 208 makes a circular motion around the axis of the rotating shaft. The eccentric shaft 211 pulls the push-pull arm 210 through the traction arm 209. The push-pull arm 210 is fixedly connected to the push platform 206, thereby pulling the push platform 206 to make a linear motion in the push port 205 towards the lower feed port 204. The front end of the push platform 206 pushes the seal located at the end of the feed trough 201, and pushes the seal out of the feed trough 201 laterally from the feed port 204. Since the feed port 204 is located on one side of the valve body and the seal is smaller than the middle cavity of the valve body, the seal is directly pushed into the valve body and falls above the sealing groove inside the valve body.

[0081] As the lifting platform 304 continues to descend, the lower end of the pressure plug 303 passes through the central opening of the valve body and enters the interior of the valve body. The lower end face of the pressure plug 303 contacts the sealing element located inside the valve body. As the lifting platform 304 continues to descend, the pressure plug 303 applies downward pressure to the sealing element, pressing the sealing element vertically into the predetermined annular sealing groove along the inner wall of the valve body until the pressure plug 303 descends to the preset end point of the stroke, and the sealing element is fully pressed into place, completing one pressing action.

[0082] After pressing is completed, the second motor 306 reverses, driving the transmission screw 305 to rotate in the opposite direction. The lifting platform 304 moves upward along the guide column 307. The pressure plug 303 is gradually lifted from inside the valve body and rises to reset. During the process of the lifting platform 304 rising, the drive rack 605 moves upward accordingly, driving the transmission gear 604 to rotate in the opposite direction. The transmission system 600 transmits power in the opposite direction, the rotating disk 208 rotates in the opposite direction, and the eccentric shaft 211 pulls the pusher platform 206 to move in a straight line back towards the pusher port 205 through the traction arm 209 and the push-pull arm 210. The front end of the pusher platform 206 is pulled out from inside the material groove 201 and completely retracted into the pusher port 205 or behind the pusher port 205. At this time, the subsequent seals in the material groove 201 are automatically moved forward by one seal position under the pushing force of the continuous feeding of the vibrating plate and the squeezing action of the seals behind, filling the end of the material groove 201 and becoming a new seal to be pushed, preparing for the next push.

[0083] At this point, the pressing cycle of a single valve body is completed. The first motor 102 is started again, driving the material tray 101 to continue rotating by one indexing angle, moving the valve body that has been pressed out from the pressing station, and at the same time, moving the next set of positioning sleeves 104 that already carries the valve body to be pressed into the pressing station, and starting the next pressing cycle.

[0084] While the pressing cycle is in progress, the feeding system 400 and the unloading system 500 operate in parallel at their respective workstations. The multi-axis motion gripping module 401 of the unloading system 500 is driven by the third motor 406 and the fourth motor 410 to move its gripper 411 above the positioning sleeve 104 where the pressed valve body is located. The gripper 411 descends and closes to grab the finished valve body, then rises and moves laterally above the unloading conveyor belt device 402. The gripper 411 opens to release the valve body, and the finished valve body is transported to the subsequent process by the unloading conveyor belt device 402. When the vacated positioning sleeve 104 continues to rotate with the material tray 101 to the feeding station, the multi-axis motion gripping module 401 of the feeding system 400 puts in a new unassembled valve body again.

[0085] The intermittent rotary feeding of the material tray 101, the automatic feeding of the sealing component by the vibratory feeder and the pusher 206, the lifting and pressing of the pressure plug 303, and the parallel picking and placing operations of the loading system 400 and the unloading system 500 are repeated in the process of equipment operation, continuously completing the automated pressing production of large batches of ball valve sealing components.

[0086] During the above-mentioned operation, since the forward movement of the pusher 206 and the downward movement of the pressure plug 303 are rigidly synchronized through the same transmission system 600, and the backward movement of the pusher 206 and the upward movement of the pressure plug 303 are also rigidly synchronized through the same transmission system 600, there is no signal delay or response lag at the electrical control level between the two. The pushing action is always completed before the pressure plug 303 is lowered into place, and the reset of the pusher 206 is always completed synchronously during the upward movement of the pressure plug 303, ensuring the timing accuracy and operational reliability of each work cycle.

[0087] In addition, since multiple sets of positioning sleeves 104 are arranged in a ring array on the material tray 101, and the three stations of loading, pressing and unloading operate in parallel, the material tray 101 completes the pressing of a valve body and simultaneously completes the loading of a new valve body and the unloading of a finished valve body for each rotation of the material tray 101 by one indexing angle. The production cycle of the equipment is only limited by the rotation speed of the material tray 101 and the lifting speed of the pressure plug 303. There is no additional waiting time for loading and unloading, thus realizing highly efficient continuous batch production.

[0088] Meanwhile, since the guide column 307 in the pressing mechanism 300 guides the lifting platform 304 in a straight line throughout the entire process, and the center line of the pressure plug 303 and the valve body are kept coincident at the pressing position, coupled with the precise limitation of the valve body position by the positioning sleeve 104, the seal is subjected to uniform force and the pressing direction is vertical during the entire pressing process, ensuring the consistency of the pressing depth and the integrity of the seal.

[0089] Through the compact arrangement of the above-mentioned mechanisms in terms of structure and the sequential coordination of their actions, the ball valve seal pressing equipment of the present invention can completely replace the traditional manual pressing operation, significantly improving production efficiency while effectively ensuring the consistency and reliability of pressing quality.
