Description

Technical Field

[0001] This invention relates to the field of solenoid valve manufacturing equipment, specifically to a continuous press-fitting production and processing device for solenoid valve cores. Background Technology

[0002] In the manufacturing process of solenoid valves, the valve core, as a core component, directly affects the sealing performance and operational reliability of the solenoid valve due to its assembly quality. Among these processes, the press-fitting of the valve core and the sealing ring is a critical step, requiring precise positioning and a tight fit of the sealing ring on the valve core to meet the sealing requirements of the solenoid valve.

[0003] Patent CN222199514U discloses a solenoid valve core production and processing device. Driven by a motor, a turntable rotates, allowing the valve core to be transferred from the valve core loading box to the sealing ring pressing machine for sealing ring pressing. After pressing, the core falls directly into the finished product collection box for collection, achieving automatic continuous pressing operations, reducing manual operation, and thus improving work efficiency. Furthermore, through the cooperation of an electric push rod, connecting rope, arc-shaped clamping plate, and torsion spring, when the valve core is transferred to the pressing position, the extension and retraction of the electric push rod automatically clamps the valve core, ensuring stable positioning of the valve core during sealing ring pressing.

[0004] Although the above solution achieves continuous press-fitting, the adaptability of the above device to valve core specifications may be limited. If valve cores of different sizes need to be processed, it may be necessary to replace the turntable or adjust the arc clamp and other components. If the above device is used to fix valve cores of different diameters, the axis of different valve cores will be fixed in different positions, which will cause the position of the press-fitting mechanism to be adjusted during the press-fitting process. Summary of the Invention

[0005] To address the aforementioned issues, a continuous press-fitting production and processing device for solenoid valve cores is provided. By setting up a turntable and multiple fixed structures, the axis of valve cores with different diameters remains in the same position after being clamped, thereby ensuring the precise press-fitting of valve cores of different specifications by the press-fitting mechanism.

[0006] To address the problems of existing technologies, this invention provides a continuous pressing and processing device for electromagnetic valve cores, comprising a turntable disposed between a valve core feeding structure and a pressing mechanism. Multiple receiving grooves are evenly spaced on the circumference of the turntable, and each receiving groove is equipped with a fixing structure, which includes a support structure and a clamping structure. The support structure includes two support plates and a first driving assembly. The two support plates are respectively disposed on the front and rear sides of the turntable along its axial direction. Two intersecting first sliding grooves are formed on the support plates, and each of the two first sliding grooves is equipped with a linkage docking assembly, which includes a linkage rod slidably disposed within the first sliding groove. The first driving assembly drives the two support plates to move radially along the turntable. The clamping structure includes two clamping plates, respectively disposed on the front and rear sides of the turntable along its axial direction, and the clamping plates are movable radially along the turntable. Two second sliding grooves at a 90-degree angle are formed on the clamping plates, and the second sliding grooves are slidably connected to the linkage rod.

[0007] Preferably, the clamping structure further includes a docking structure, which includes two connecting blocks and a bidirectional drive assembly; the two connecting blocks are respectively connected to two clamping plates; the two ends of the bidirectional drive assembly are respectively connected to the two connecting blocks, and the bidirectional drive assembly is used to drive the two connecting blocks to run in opposite directions along the axis of the turntable.

[0008] Preferably, the bidirectional drive assembly includes a sealing cylinder and two telescopic rods; the sealing cylinder is parallel to the axis of the turntable, and an inlet / outlet is provided in the middle of the sealing cylinder, with valves installed on the inlet / outlet; the two telescopic rods are respectively at both ends of the sealing cylinder, one end of the telescopic rod extends into the sealing cylinder, and the other end of the telescopic rod is connected to the connecting block.

[0009] Preferably, the docking structure further includes two second guide components, which are respectively connected to the two connecting blocks. The second guide components are used to maintain the translational movement of the connecting blocks.

[0010] Preferably, at least two sliding connection components are provided between the clamping plate and the connecting block. The two ends of the sliding connection components are connected to the clamping plate and the connecting plate respectively. The sliding connection components are used to maintain the translational movement of the clamping plate.

[0011] Preferably, the first drive assembly includes a rotating shaft, two cams, and a self-locking assembly; the rotating shaft is parallel to the axis of the turntable; the two cams are respectively disposed at both ends of the rotating shaft, and the cams rotate synchronously with the rotating shaft, with the outer peripheral surface of the cams abutting against the support plate; the self-locking assembly is used to fix the rotating shaft.

[0012] Preferably, the self-locking component includes a screw sleeve, which is fixedly connected to the turntable. The screw sleeve has an internal thread, and the rotating shaft is installed inside the screw sleeve and has an external thread that mates with the internal thread.

[0013] Preferably, the linkage docking assembly further includes a guide limiting assembly, which includes a first guide rod and a first spring; the two ends of the first guide rod are respectively connected to the two ends of the first slide groove, and a slider is slidably disposed on the first guide rod, with the linkage rod mounted on the slider; the first spring is used to keep the slider abutting against the groove wall of the first slide groove.

[0014] Preferably, the support structure further includes two first guide components, which are respectively connected to two support plates. The first guide components are used to restrict the movement of the support plates along the radial direction of the turntable.

[0015] Preferably, a support structure is provided on one side of the turntable for supporting the end of the valve core in the axial direction of the turntable.

[0016] The advantages of this invention compared to the prior art are: 1. This invention features a turntable and multiple fixed structures. The turntable rotates around its own axis to achieve continuous transfer of the valve core between different workstations. The supporting structure and clamping structure in the fixed structures work together. Through the parallelogram formed by the two first sliding grooves on the support plate and the two second sliding grooves on the clamping plate in the supporting structure, and the linkage between the linkage rod and the first and second sliding grooves in the linkage assembly, the axis of valve cores of different diameters remains in the same position after being clamped. This ensures that the pressing mechanism can accurately align the valve core for pressing, thereby ensuring that the axis of valve cores of different diameters remains in the same position after being clamped, and thus ensuring the accurate pressing of valve cores of different specifications by the pressing mechanism.

[0017] 2. The present invention features a docking structure. The bidirectional drive component in the docking structure drives two connecting blocks to move, thereby causing two clamping plates to open and close in the axial direction. This not only reserves space for valve cores of different lengths to smoothly enter the support plate area, but also drives the clamping plates to dock with the support plate after the valve cores are in place, laying the foundation for the subsequent movement of the support structure and the clamping structure. This ensures that valve cores of different lengths can be smoothly placed on the support plate, avoiding the clamping plates from obstructing the valve core loading process.

[0018] 3. The present invention is provided with a sealing cylinder, two telescopic rods and a valve. The inner cavity of the sealing cylinder is divided into a driving cavity in the middle and a compression cavity on both sides. By the filling and releasing of the medium in the driving cavity and the pressure change, the two telescopic rods are controlled to drive the two clamping plates to move. The pressure in the driving cavity can remain unchanged after the valve is closed, so that the position of the two telescopic rods is locked, thereby ensuring that the clamping plates remain unchanged during the rotation of the turntable and will not shift due to centrifugal force or vibration.

[0032] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1 to 12 As shown: A continuous pressing and processing device for electromagnetic valve cores includes a turntable 1 disposed between a valve core feeding structure and a pressing mechanism. Multiple receiving slots 11 are evenly spaced on the circumference of the turntable 1. Each receiving slot 11 is equipped with a fixing structure, which includes a support structure 2 and a clamping structure 3. The support structure 2 includes two support plates 21 and a first driving assembly 22. The two support plates 21 are respectively disposed on both sides of the turntable 1. Two intersecting first sliding grooves 211 are formed on the support plates 21. Each of the two first sliding grooves 211 contains... A linkage docking assembly 23 is provided, which includes a linkage rod 231. The linkage rod 231 is slidably disposed in the first slide groove 211. The first drive assembly 22 is used to drive the two support plates 21 to move along the radial direction of the turntable 1. The clamping structure 3 includes two clamping plates 31, which are respectively disposed on both sides of the turntable 1 and can move along the radial direction of the turntable 1. Two second slide grooves 311 with a 90-degree angle are opened on the clamping plates 31, and the second slide grooves 311 are slidably connected to the linkage rod 231.

[0034] After the device is started, the turntable 1 begins to rotate around its own axis. When one of the receiving slots 11 on the turntable 1 rotates to align with the valve core feeding structure, the valve core feeding structure transfers the valve core into the receiving slot 11, completing the initial placement of the valve core. Subsequently, the turntable 1 continues to drive the valve core to rotate. During the rotation of the valve core by the turntable 1, the fixing structure fixes the valve core. When it is necessary to process valve cores of different diameters, after the valve core is transferred to the receiving slot 11, the support structure 2 is activated. The two support plates 21 in the support structure 2 abut against the two ends of the valve core, ensuring that the valve core remains in contact with the valve core. With the turntable 1 parallel to its axis, the two clamping plates 31 in the clamping structure 3 move closer to the support plate 21 and dock. At this time, the linkage rod 231 in the linkage docking assembly 23 simultaneously embeds into the first slide groove 211 and the second slide groove 311 and forms a sliding connection. The two first slide grooves 211 and the two second slide grooves 311 together form a parallelogram structure. The valve core is located in the enclosed space between the support plate 21 and the clamping plate 31. Then, the first drive assembly 22 is activated, driving the two support plates 21 away from the center of the turntable 1 along the radial direction. Due to the linkage... Rod 231 slides simultaneously within the first slide groove 211 and the second slide groove 311, and the two first slide grooves 211 and the two second slide grooves 311 together form a parallelogram. The movement of the support plate 21 will drive the clamping plate 31 to move synchronously through the linkage rod 231, so that the support plate 21 and the clamping plate 31 face each other and move towards the valve core synchronously. When both are in contact with the surface of the valve core, the valve core is stably clamped. Due to the synchronous movement characteristics of the support plate 21 and the clamping plate 31, valve cores of different diameters are clamped, and their axes are always in the same position, ensuring consistent positioning. When the turntable... When the fixed valve core is rotated to the pressing mechanism, the pressing mechanism accurately aligns with the valve core and completes the pressing process of the sealing ring. After pressing, the turntable 1 continues to rotate, taking the processed valve core away from the pressing station. At the same time, the next valve core to be processed enters the pressing area, realizing continuous production. Through the coordinated cooperation of the supporting structure 2 and the clamping structure 3, and by utilizing the linkage of the parallelogram structure and the linkage docking component 23, valve cores of different diameters are clamped so that their axes always remain in the same position, thereby ensuring the accurate pressing of valve cores of different specifications by the pressing mechanism.

[0035] Reference Figure 3 and Figure 4 As shown: The clamping structure 3 also includes a docking structure 32, which includes two connecting blocks 321 and a bidirectional drive assembly 322; the two connecting blocks 321 are respectively connected to the two clamping plates 31; the two ends of the bidirectional drive assembly 322 are respectively connected to the two connecting blocks 321, and the bidirectional drive assembly 322 is used to drive the two connecting blocks 321 to run in opposite directions along the axial direction of the turntable 1.

[0036] When the receiving groove 11 on the turntable 1 is about to dock with the valve core feeding structure, the docking structure 32 is activated in advance. At this time, the bidirectional drive component 322 operates, and its two ends drive the two connecting blocks 321 connected to it to move in opposite directions along the axial direction of the turntable 1. That is, the two connecting blocks 321 move away from each other. The movement of the connecting blocks 321 simultaneously drives the two clamping plates 31 to move away from each other, so that the distance formed between the two clamping plates 31 is greater than the length of the valve core to be transferred, leaving enough space for the valve core to smoothly enter the area of ​​the support plate 21. Subsequently, the valve core feeding structure transfers the valve core into the receiving groove 11. After the valve core is stably placed on the two support plates 21, the docking structure 32 is activated again, and the bidirectional drive component 322 operates in reverse, driving the two connecting blocks 321 to move in opposite directions along the axial direction of the turntable 1. As the clamping plates move closer to each other, the connecting block 321 drives the two clamping plates 31 to move closer to each other synchronously. As the clamping plates 31 move, they gradually move closer to the support plate 21 until the clamping plates 31 and the support plate 21 are completely in contact. At this time, the second sliding groove 311 on the clamping plate 31 connects with the linkage rod 231 in the linkage docking assembly 23 on the support plate 21, so that the linkage rod 231 is simultaneously embedded in the first sliding groove 211 and the second sliding groove 311. This prepares for the subsequent synchronous movement of the support structure 2 and the clamping structure 3 through the parallelogram structure. The bidirectional drive assembly 322 drives the connecting block 321 and the clamping plate 31 to open and close in the axial direction, thereby ensuring that valve cores of different lengths can be smoothly placed on the support plate 21, avoiding the clamping plate 31 from obstructing the valve core loading process.

[0037] Reference Figure 3 , Figure 4 and Figure 5 As shown: the bidirectional drive assembly 322 includes a sealing cylinder 3221 and two telescopic rods 3222; the sealing cylinder 3221 is parallel to the axis of the turntable 1, and an inlet and outlet are provided in the middle of the sealing cylinder 3221, with a valve 3223 provided on the inlet and outlet; the two telescopic rods 3222 are respectively at both ends of the sealing cylinder 3221, one end of the telescopic rod 3222 extends into the sealing cylinder 3221, and the other end of the telescopic rod 3222 is connected to the connecting block 321.

[0038] The interior of the sealing cylinder 3221 is divided into three chambers by two telescopic rods 3222. The middle chamber is the drive chamber, and the two sides are compression chambers connected to the outside atmosphere. The inlet and outlet of the drive chamber are controlled by valve 3223 to switch on and off with the external air or liquid source. Before the supporting structure 2 is about to be transferred to dock with the valve core feeding structure, valve 3223 is opened, and the external air or liquid source injects gas or liquid into the drive chamber of the sealing cylinder 3221 through the inlet and outlet. As the medium in the drive chamber increases and the pressure rises, the pressure acts on the ends of the two telescopic rods 3222 located in the drive chamber, pushing the two telescopic rods 3222 to move towards the two ends of the sealing cylinder 3221 and separate from each other. The movement of the telescopic rods 3222 synchronously drives the connecting block 321 connected to them, thereby causing the two clamping plates 31 to move away from each other along the axis of the turntable 1. When the distance between the two clamping plates 31 is greater than the length of the valve core to be fed, valve 3223 is closed, and the pressure in the drive chamber remains fixed. The position of the telescopic rod 3222 is locked to ensure that the clamping plate 31 will not obstruct the transfer of the valve core during the valve core feeding process. After the valve core is transferred to the two support plates 21, the bidirectional drive assembly 322 is started again. At this time, the valve 3223 is opened again, and the external equipment extracts the gas or liquid in the drive chamber of the sealing cylinder 3221 through the inlet and outlet ports. The pressure in the drive chamber gradually decreases. Since the compression chambers on both sides are connected to the atmosphere, under the action of the internal and external pressure difference, the two telescopic rods 3222 are subjected to inward suction and move closer to each other, driving the connecting block 321 and the clamping plate 31 to move synchronously towards the support plate 21 until the clamping plate 31 docks with the support plate 21. After the linkage rod 231 is simultaneously embedded in the first slide groove 211 and the second slide groove 311, the valve 3223 is closed, and the drive chamber is kept in a low-pressure state, so that the position of the two telescopic rods 3222 is locked, thereby ensuring that the clamping plate 31 remains unchanged during the rotation of the turntable 1 and will not shift due to centrifugal force or vibration.

[0039] Reference Figure 3 , Figure 4 and Figure 5 As shown: The docking structure 32 also includes two second guide components 323, which are respectively connected to two connecting blocks 321. The second guide components 323 are used to keep the connecting blocks 321 from translating.

[0040] Specifically, the second guide assembly 323 includes at least two third guide rods 3231, one end of which is fixedly connected to the connecting block 321, and the other end of which is vertically inserted into the turntable 1.

[0041] When gas or liquid is injected into the drive chamber of the bidirectional drive assembly 322, pushing the two telescopic rods 3222 to separate, the telescopic rods 3222 drive the connecting block 321 to move away from the center of the turntable 1. At this time, the third guide rod 3231, which is fixedly connected to the connecting block 321, moves synchronously. Since the third guide rod 3231 is inserted perpendicularly into the turntable 1 and can only slide relative to the turntable 1 along its own axis, it constrains the movement of the connecting block 321. Originally, when the connecting block 321 was only connected to the telescopic rod 3222, it had a degree of freedom to rotate around the axis of the telescopic rod 3222. However, under the constraint of the third guide rod 3231, the connecting block 321 cannot rotate and can only move in a direction perpendicular to the turntable 1. The translational movement ensures that the clamping plate 31 driven by the connecting block 321 always maintains the correct posture. When the gas or liquid in the drive cavity is extracted, the two telescopic rods 3222 approach each other under the action of pressure difference, driving the connecting block 321 to move towards the center of the turntable 1. The third guide rod 3231 also moves synchronously with the connecting block 321. Under the relative sliding cooperation between the third guide rod 3231 and the turntable 1, the connecting block 321 can still only translate along the direction perpendicular to the turntable 1, avoiding rotational deviation of the connecting block 321 during the movement. This ensures the precise docking of the second slide groove 311 on the clamping plate 31 and the linkage rod 231 on the support plate 21, avoiding docking deviation caused by the rotation of the connecting block 321.

[0042] Reference Figure 5 and Figure 6 As shown: At least two sliding connection components 33 are provided between the clamping plate 31 and the connecting block 321. The two ends of the sliding connection components 33 are connected to the clamping plate 31 and the connecting block 321 respectively. The sliding connection components 33 are used to keep the clamping plate 31 from translating.

[0043] Specifically, both ends of the clamping plate 31 are provided with third sliding grooves 312. The sliding connection assembly 33 includes a fourth guide rod 331 and a second spring 332. One end of the fourth guide rod 331 is fixedly connected to the connecting block 321, and the other end of the fourth guide rod 331 is slidably disposed in the third sliding groove 312. The second spring 332 is disposed in the third sliding groove 312, and both ends of the second spring 332 abut against the end of the fourth guide rod 331 and the groove wall of the third sliding groove 312, respectively. The second spring 332 is used to apply a force to the clamping plate 31 in a direction away from the connecting block 321.

[0044] In the initial state, under the elastic force of the second spring 332, the clamping plate 31 is pushed away from the connecting block 321 and held in a fixed position by the constraint at the end of the fourth guide rod 331. At this time, the distance between the end of the fourth guide rod 331 and the groove wall in the third slide groove 312 is at its maximum, and the second slide groove 311 on the clamping plate 31 is in the preset docking position. When the docking structure 32 drives the connecting block 321 to move the clamping plate 31 closer to the support plate 21, the fixed position of the clamping plate 31 ensures that the clamping plate 31... The second slide groove 311 can align and engage with the linkage rod 231 on the support plate 21. After the clamping plate 31 and the support plate 21 are engaged, the first drive assembly 22 starts and drives the support plate 21 radially away from the center along the turntable 1. At this time, the support plate 21 moves the clamping plate 31 radially synchronously through the sliding engagement of the linkage rod 231 and the second slide groove 311. Since the clamping plate 31 needs to move radially with the support plate 21, and the position of the connecting block 321 is relatively fixed, the clamping plate 31 will move along the fourth guide rod 331. As the third slide groove 312 slides towards the connecting block 321, its wall gradually approaches the end of the fourth guide rod 331. The second spring 332 is compressed, gradually storing elastic potential energy. During this process, the sliding engagement between the fourth guide rod 331 and the third slide groove 312 provides stable guidance for the radial movement of the clamping plate 31, ensuring that the clamping plate 31 moves only in a preset direction and avoiding deviation. When the valve core needs to be released, the first drive assembly 22 drives the support plate 21 to move towards the center of the turntable 1. At the same time, the third slide groove 312 is compressed. The second spring 332 releases some of its elastic potential energy, pushing the end of the fourth guide rod 331 to separate from the wall of the third slide groove 312. This causes the clamping plate 31 to move away from the connecting block 321 along the fourth guide rod 331 and gradually return to its initial position, preparing for the next valve core clamping. Through the cooperation of the fourth guide rod 331, the second spring 332, and the third slide groove 312, a stable guide is provided for the clamping plate 31 to move radially along the turntable 1, thereby achieving smoothness and reliability in clamping and releasing valve cores of different specifications.

[0045] Reference Figure 4 and Figure 7 As shown: The first drive assembly 22 includes a rotating shaft 221, two cams 222 and a self-locking assembly 224; the rotating shaft 221 is parallel to the axis of the turntable 1; the two cams 222 are respectively disposed at both ends of the rotating shaft 221, and the cams 222 rotate synchronously with the rotating shaft 221, and the outer peripheral surface of the cams 222 abuts against the support plate 21; the self-locking assembly 224 is used to fix the rotating shaft 221.

[0046] Initially, the base circle portion of cam 222 abuts against the support plate 21, and the space between the support plate 21 and the clamping plate 31 is at its maximum. When the rotating shaft 221 starts to rotate, since the two cams 222 rotate synchronously with the rotating shaft 221, the two cams 222 will rotate together around the axis of the rotating shaft 221. During the rotation, the protruding end of the cam 222 gradually contacts the support plate 21. Because the position of the rotating shaft 221 is fixed, as the cam 222 continues to rotate, the protruding end exerts a pushing force on the support plate 21, forcing the support plate 21 to move along the turntable. The radial direction of the rotating shaft 221 moves away from the center of the rotating disk 1. When the supporting plate 21 moves, the clamping plate 31 moves synchronously through the linkage rod 231 in the linkage docking assembly 23. This causes the supporting plate 21 and the clamping plate 31 to face each other and move towards the valve core synchronously. When the supporting plate 21 and the clamping plate 31 both abut against the valve core and clamp the valve core, the rotating shaft 221 stops rotating. At this time, the self-locking assembly 224 fixes the rotating shaft 221 in the current position, so that the contact position between the cam 222 and the supporting plate 21 remains unchanged, thereby ensuring that the clamping state of the supporting plate 21 and the clamping plate 31 on the valve core is stable and reliable.

[0047] Reference Figure 3 , Figure 7 and Figure 8 As shown: The self-locking assembly 224 includes a screw sleeve 2241, which is fixedly connected to the turntable 1. The screw sleeve 2241 has an internal thread, and the rotating shaft 221 is installed inside the screw sleeve 2241. The rotating shaft 221 has an external thread that mates with the internal thread.

[0048] In the initial state, without external driving force, the threaded engagement between the rotating shaft 221 and the screw sleeve 2241 keeps the rotating shaft 221 stationary, and the base circle of the cam 222 remains in contact with the support plate 21. When it is necessary to drive the support plate 21 to move to clamp the valve core, a rotational force is applied to the rotating shaft 221 around its own axis. Due to the transmission effect of the thread, the rotating shaft 221 moves along its own axis while rotating, and the cams 222 at both ends rotate and move axially synchronously with the rotating shaft 221. During this process, the cams 222 always remain in contact with the support plate 21. After the support plate 21 and the clamping plate 31 clamp the valve core, the rotational force applied to the rotating shaft 221 is stopped. When force is applied, the threaded engagement between the rotating shaft 221 and the threaded sleeve 2241 immediately locks the position of the rotating shaft 221, preventing it from rotating or moving axially. The position of the cam 222 is thus fixed, and the clamping force of the support plate 21 and the clamping plate 31 on the valve core is maintained. When the valve core needs to be released, a reverse rotational force is applied to the rotating shaft 221 again, causing the rotating shaft 221 to rotate in the opposite direction and move in the opposite direction axially. The support plate 21 and the clamping plate 31 are reset, and then the force is stopped. The threaded engagement locks the position of the rotating shaft 221 again. Through the threaded engagement between the rotating shaft 221 and the threaded sleeve 2241, the rotating shaft 221 is automatically stationary when there is no external force, preventing the clamping force from loosening.

[0049] Reference Figure 3 , Figure 9 and Figure 10 As shown: the linkage docking assembly 23 also includes a guide limiting assembly 232, which includes a first guide rod 2321 and a first spring 2323; the two ends of the first guide rod 2321 are respectively connected to the two ends of the first slide groove 211, and a slider 2322 is slidably disposed on the first guide rod 2321, and the linkage rod 231 is installed on the slider 2322; the first spring 2323 is used to keep the slider 2322 in contact with the groove wall of the first slide groove 211.

[0050] In the initial state, the first spring 2323 applies a force to the slider 2322, pushing the slider 2322 to the end of the first guide rod 2321. At this time, the linkage rod 231 remains fixed on the support plate 21. This fixed position ensures that the linkage rod 231 engages with the second slide groove 311 on the clamping plate 31, ensuring that the linkage rod 231 can accurately enter the second slide groove 311 when the clamping plate 31 moves closer to the support plate 21. After the clamping plate 31 engages with the support plate 21, the first drive assembly 22 drives the support plate 21 to move radially away from the center along the turntable 1. At this time, the support plate 21 drives the linkage rod 231 through the first slide groove 211, while the linkage rod 231 is constrained by the second slide groove 311. Under the combined action of the two, the linkage rod 231 drives the slider 2322 to move radially away from the center. Block 2322 moves along the first guide rod 2321. As the slider 2322 moves, the first spring 2323 is compressed, storing elastic potential energy. When the valve core is pressed and needs to be released, the first drive assembly 22 drives the support plate 21 to move closer to the center of the turntable 1. The force exerted by the support plate 21 on the linkage rod 231 decreases. At this time, the compressed first spring 2323 releases its elastic potential energy, pushing the slider 2322 to move in the opposite direction along the first guide rod 2321 and return to the end of the first guide rod 2321. The linkage rod 231 also returns to its initial fixed position, preparing for the next docking with the second slide groove 311 of the clamping plate 31. This achieves the goal of fixing the linkage rod 231 in the preset position in the initial state, ensuring docking with the second slide groove 311.

[0051] Reference Figure 7 and Figure 11 As shown: The support structure 2 also includes two first guide components 24, which are respectively connected to two support plates 21. The first guide components 24 are used to restrict the support plates 21 from moving along the radial direction of the turntable 1.

[0052] Specifically, the first guide assembly 24 includes at least two second guide rods 241, which are slidably connected to the support plate 21, and one end of the second guide rod 241 is fixedly connected to the turntable 1.

[0053] When the rotating shaft 221 in the first drive assembly 22 drives the cam 222 to rotate, and the protruding end of the cam 222 contacts the support plate 21 and applies a force toward the outside of the turntable 1, the support plate 21 begins to move. Since the second guide rod 241 is slidably connected to the support plate 21 and one end is fixed on the turntable 1, the support plate 21 will move outward along the axial direction of the second guide rod 241, that is, the radial direction of the turntable 1. During the movement, the two second guide rods 241 form stable support and guidance for the support plate 21, ensuring that the support plate 21 will not deviate from the radial direction of rotation or offset, but can only perform translational movement. At the same time, the two support plates 21 maintain the same movement state under the action of the corresponding first guide assembly 24, that is, the movement direction is consistent and the movement speed is synchronized, thereby ensuring that the two support plates 21 always uniformly abut against both ends of the valve core, so that the valve core maintains a posture parallel to the axis of the turntable 1.

[0054] Reference Figure 3 and Figure 12 As shown: A support structure 4 is provided on one side of the turntable 1 for supporting the end of the valve core in the axial direction of the turntable 1.

[0055] Specifically, the support structure 4 includes an arc-shaped support plate 41 and multiple linear actuators 42. The arc-shaped support plate 41 is coaxially arranged with the turntable 1. The multiple linear actuators 42 are in contact with multiple parts of the arc-shaped support plate 41, and the multiple linear actuators 42 are used to synchronously apply a force to the arc-shaped support plate 41 along the axis of the turntable 1.

[0056] Initially, the arc-shaped support plate 41 is positioned away from the turntable 1, not affecting the valve core's entry into the support structure 2. When the valve core moves into the receiving groove 11 of the turntable 1, the turntable 1 drives the valve core to rotate. As the turntable 1 rotates, when the valve core enters the coverage area of ​​the arc-shaped support plate 41, multiple linear actuators 42 are simultaneously activated, applying a force along the axis of the turntable 1 towards the arc-shaped support plate 41. Due to the simultaneous force exerted by multiple linear actuators 42, the arc-shaped support plate 41 remains flush with the side of the turntable 1. The valve core moves towards the turntable 1. When the arc-shaped support plate 41 contacts the end of the valve core, it will continue to push the valve core to move until the end of the valve core is pushed to the same preset plane. Then, the clamping structure 3 and the supporting structure 2 clamp and fix the valve core. When the pressing mechanism presses the valve core to install the sealing ring, the valve core will be subjected to a force along its own axial direction. At this time, the arc-shaped support plate 41 is attached to the end of the valve core to provide axial support for the valve core, balance the force during pressing, and thus prevent the valve core from shifting in the axial direction during the pressing process.
