Description

Technical Field

[0001] This application relates to the field of air valve processing technology, and in particular to an air valve push rod press-fitting device. Background Technology

[0002] Pneumatic valves are widely used industrial devices that use compressed air to drive multiple sets of combined pneumatic pistons within an actuator, thereby controlling fluid flow. Common pneumatic valves include a balancing valve core and a push rod. The push rod is fixedly connected to the balancing valve core and guides its movement. The valve core is used to control the fluid.

[0003] In related technologies, the balance valve core and push rod are usually assembled as two independent parts. The balance valve core has a connecting hole for the push rod to be inserted, and the push rod and the connecting hole are interference-fitted. During assembly, a pressing device is needed to manually press the push rod into the connecting hole. The end of the push rod that passes through the connecting hole has a chamfer. After the push rod passes through the connecting hole, a riveting device is needed to manually rivet the balance valve core. After riveting, the end of the connecting hole on the balance valve core deforms towards the chamfer of the push rod, eventually covering the chamfer and improving the connection stability and reliability of the balance valve core and the push rod.

[0004] In the process of developing this application, it was found that the technology has at least the following problems: During the assembly process, it is necessary to manually switch the balance valve core and push rod between the pressing device and the riveting device, and control the two devices. This is easy to cause confusion, is time-consuming and labor-intensive, and results in low production efficiency. Summary of the Invention

[0005] In order to improve the assembly efficiency of the push rod and the balance valve core and reduce manual operation steps, this application provides a valve push rod press-fitting device.

[0006] The technical solution of the valve push rod press-fitting device provided in this application is as follows: A valve push rod pressing device includes a worktable, a support, and a processor. The support is located above the worktable and is fixedly connected to it. A slide block is slidably mounted on the worktable in a horizontal direction. A first driving member is provided on the worktable to drive the slide block to slide. A pressing support and a riveting support are provided on the slide block, and the pressing support and the riveting support are arranged at intervals along the sliding direction of the slide block. The top of the pressing support has a first receiving groove for vertically placing the push rod, and the bottom wall of the first receiving groove can abut against the bottom of the push rod. The top of the riveting support has a second receiving groove adapted to the balance valve core, and the bottom wall of the second receiving groove can abut against the balance valve core. The bottoms of the valve cores abut against each other, and a third receiving groove is provided on the bottom wall of the second receiving groove for the push rod to extend into; a pressure block is slidably arranged on the bracket in the vertical direction, and a second driving member is provided on the bracket for driving the pressure block to slide; a pressing table and a riveting table are fixedly provided at the bottom of the pressure block, and the pressing table and the riveting table are arranged at intervals along the sliding direction of the slide block, and the pressing table is located directly above the pressing support; a loading assembly is provided at the bottom of the pressing table, and the loading assembly is used to load or release the balance valve core, and a riveting head is provided at the bottom of the riveting table for riveting the balance valve core; the first driving member, the second driving member, and the loading assembly are all electrically connected to the processor.

[0007] By adopting the above technical solution, when assembling the push rod and the balance valve core, the push rod is placed in the first receiving groove with the chamfered end facing upwards. The balance valve core is then loaded onto the bottom of the pressing platform by the loading assembly, at which point the push rod is vertical and directly opposite the connection hole of the balance valve core. Next, the pressing block slides for the first time: driven by the second driving component, the pressing platform moves downwards, pressing the balance valve core against the push rod. The push rod passes through the connection hole of the balance valve core and is interference-fitted with the push rod. Then, driven by the second driving component, the pressing block moves upwards, and the pressing platform lifts the balance valve core and the push rod together. Next, the slide moves for the first time: the first driving component pushes the slide to move, positioning the riveting support directly below the pressing platform. Next, the pressing block slides for the second time: the pressing block moves downwards, and the pressing platform sends the balance valve core into the second receiving groove, while the push rod enters the third receiving groove. Then, after the loading assembly releases the balance valve core, the pressing block moves upwards. Next, the slide moves for the second time, positioning the riveting support directly below the riveting platform. Next, the pressure block moves downwards for the third time: pressing the riveting head against the balance valve core. After riveting, the end of the connecting hole deforms towards the chamfer of the push rod, covering the local chamfer. Then, the pressure block moves upwards, leaving the assembled push rod and balance valve core on the riveting table. Finally, the slide moves for the third time, and the pressing support is positioned back below the pressing table, completing the reset. The entire process reduces the number of manual steps involved in moving parts between different devices and operating the equipment, increasing automation, improving production efficiency, and eliminating the need for manual handling of parts.

[0008] Preferably, the loading assembly includes an electric suction cup, which is fixedly connected to the pressing table and can hold the balance valve core.

[0009] By adopting the above technical solution, when the electric suction cup is activated, it generates suction force to quickly hold the balance valve core, ensuring that the balance valve core will not shift or fall off during transportation. When it is necessary to release the balance valve core, the electric suction cup is turned off, the suction force disappears, and the balance valve core is placed in the second receiving groove.

[0010] Preferably, the loading assembly further includes a positioning element, the electric suction cup is located inside the positioning element, the positioning element is fixedly connected to the pressing table, and the bottom of the positioning element has a positioning groove adapted to the balance valve core, the top wall of the positioning groove can abut against the top of the balance valve core.

[0011] By adopting the above technical solution, the positioning component and the positioning groove at the bottom provide positioning for the balance valve core. After the balance valve core is placed in the positioning groove, the electric suction cup can hold the balance valve core, ensuring the positioning accuracy of the connection hole and the push rod; the top wall of the positioning groove abuts against the top of the balance valve core, ensuring that the top wall of the positioning groove provides reliable and uniform pressure to the balance valve core during the process of pressing the balance valve core against the push rod.

[0012] Preferably, a rotating frame is fixedly mounted on the slide, and the pressing support is rotatably connected to the rotating frame. The rotation axis of the pressing support and the rotating frame is arranged in the horizontal direction and is perpendicular to the sliding direction of the slide. A deflection component for driving the pressing support to rotate is provided on the worktable.

[0013] By adopting the above technical solution, after the push rod and the balance valve core are connected, the pressing table is no longer located directly below the pressing support. At this time, the deflection component can drive the pressing support to deflect. On the one hand, it makes the pressing support tilt and the height of the pressing support decreases, which helps to prevent the riveting table from contacting the pressing support when the pressing block moves down for the second time. On the other hand, it makes the first receiving groove tilted or horizontal, reducing the interference of the bracket on inserting the new push rod into the first receiving groove.

[0014] Preferably, the deflection assembly includes a rack and a gear. The rack is fixedly connected to the worktable and extends along the sliding direction of the slide. The gear is rotatably connected to the rotating frame. The gear is coaxial and fixedly connected to the pressing support. The gear and the rack mesh with each other.

[0015] By adopting the above technical solution, when the slide moves, the gear meshes and rotates with the rack fixed on the worktable, thereby driving the pressing bracket to automatically deflect. No additional power source is needed to control the rotation of the pressing bracket. Moreover, the meshing of the gear and the rack ensures that the deflection angle of the pressing bracket is specific no matter where the slide moves, and no uncontrollable deflection will occur. This ensures that when the pressing bracket is located directly below the pressing table, the opening of the first receiving groove of the pressing bracket faces upward.

[0016] Preferably, a loading platform is fixedly installed on the workbench, and a pre-loading groove is opened through the top of the loading platform along the sliding direction of the slide block. The pre-loading groove allows the push rod to be placed horizontally. The first receiving groove can be deflected with the pressing support to face the pre-loading groove at the end near the slide block. A push block is slidably installed in the pre-loading groove at the end away from the slide block along the sliding direction of the slide block. The push block can abut against the push rod in the pre-loading groove. The loading platform is also provided with a third driving member for driving the push block to slide.

[0017] By adopting the above technical solution, the push rod is placed horizontally in the pre-loading groove. When the slide block slides to a specific position, the gear engages with the rack, so that the first receiving groove, along with the pressing support, is aligned with the end of the pre-loading groove closest to the slide block. At this time, the third driving component pushes the push block to slide along the opening direction in the pre-loading groove. Under the push of the push block, the push rod is pushed into the first receiving groove, thus realizing the automatic replenishment of the push rod in the first receiving groove. This not only saves manpower but also improves the feeding efficiency and enhances the working continuity of the entire valve push rod pressing device.

[0018] Preferably, the top of the feeding platform is inclined and fixed with a feeding ramp, the bottom end of the feeding ramp faces the opening of the pre-loading trough, and the feeding ramp allows the push rod to roll into the pre-loading trough.

[0019] By adopting the above technical solution, when the push rod in the pre-loading trough is sent into the first receiving trough, the push block is reset, and the pre-loading trough is empty. Since the feeding inclined plate is set at an inclination and the bottom faces the opening of the pre-loading trough, the push rod will automatically roll down along the inclined plate into the pre-loading trough under the action of gravity, automatically and continuously replenishing the push rod in the pre-loading trough.

[0020] Preferably, the feeding inclined plate has side baffles integrally formed on both sides.

[0021] By adopting the above technical solution, during the process of the push rod rolling down the feeding inclined plate, the side baffle prevents the push rod from accidentally rolling down from both sides of the inclined plate, thus ensuring the continuity and stability of the feeding process. When the push rod located in the pre-loading trough slides towards the first receiving trough, it may give the push rod in the feeding inclined plate a tendency to move through contact. At this time, the side baffle can hinder the movement of the push rod in the feeding inclined plate.

[0022] Preferably, a through-beam sensor is also included. The through-beam sensor includes a transmitter and a receiver. The receiver is fixed on the loading platform near the slide, and the transmitter is fixed on the top of the pressing bracket. When the first receiving groove is directly opposite the pre-loading groove near the slide, the transmitter is directly opposite the receiver. The through-beam sensor is electrically connected to the third driving component.

[0023] By adopting the above technical solution, when the first receiving groove rotates with the pressing support to the end facing the pre-loading groove near the slide, the transmitting end is directly opposite the receiving end. At this time, the transmitting end emits a signal which is received by the receiving end. The through-beam sensor sends a command to the third driving component, which then starts and drives the push block to slide, pushing the push rod in the pre-loading groove into the first receiving groove. When the receiving end does not receive a signal, it indicates that the first receiving groove is not yet facing the end of the pre-loading groove near the slide. The through-beam sensor does not send a command to the third driving component, and the third driving component does not work. By setting the through-beam sensor, automatic detection of whether the first receiving groove is facing the end of the pre-loading groove near the slide is achieved, thereby controlling the working state of the third driving component.

[0024] Preferably, when the first receiving groove is directly opposite the pre-filled groove at one end near the slide, the riveting table is located directly above the riveting support.

[0025] By adopting the above technical solution, when the first receiving groove is directly opposite the end of the pre-loading groove near the slide, the riveting table is positioned directly above the riveting support. Simultaneously, the device can perform two tasks in parallel: firstly, the push rod can be pushed from the pre-loading groove to the first receiving groove, completing the preparation process for loading a new push rod; secondly, the riveting table can perform riveting operations on the balance valve core and push rod assembly that has already undergone the pressing process on the riveting support. This reduces equipment downtime, ensures close integration of various workflows, accelerates product output, and improves production efficiency.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a slide, a first driving component, a pressing support, a riveting support, a first receiving groove, a second receiving groove, a third receiving groove, a pressure block, a second driving component, a pressing table, a riveting table, a loading component, a riveting head, and a processor, the automated connection of the pressing and riveting process of the push rod and the balance valve core is realized, reducing the steps of frequent switching between different devices, greatly improving assembly efficiency, and reducing the intensity of manual labor; 2. By setting up an electric suction cup, positioning components, and positioning groove, the suction force of the electric suction cup is used to stably grasp the balance valve core. In conjunction with the positioning components and positioning groove, the positional accuracy of the balance valve core during handling and pressing is ensured, and the connection hole and push rod are accurately aligned. At the same time, the top wall of the positioning groove can provide reliable and uniform pressure to the balance valve core, improving the pressing quality. 3. By setting up a rotating frame, deflection assembly, rack, gear, feeding platform, pre-loading trough, push block, third drive component, and feeding inclined plate, automatic feeding of the push rod to the first receiving trough is realized. The push rod can automatically move from the feeding platform to the pre-loading trough and finally replenish the first receiving trough, further improving the working efficiency and continuity of the air valve push rod pressing device.

The push rod 8 has a chamfer 81 at the end that passes through the connecting hole 91. After the push rod 8 passes through the connecting hole 91, the balance valve core 9 needs to be riveted. After riveting, the end of the connecting hole 91 on the balance valve core 9 deforms towards the chamfer 81 of the push rod 8, ultimately covering the chamfer 81.

Specifically, a rotating frame 23 is fixedly mounted on the slide 2, and the pressing support 21 is rotatably connected to the rotating frame 23. The rotation axes of the pressing support 21 and the rotating frame 23 are set in the horizontal direction and perpendicular to the sliding direction of the slide 2. A deflection assembly 5 is provided on the worktable 1 to drive the pressing support 21 to rotate. The riveting support 22 is fixedly connected to the slide 2.

[0038] Reference Figure 3 and Figure 4 The top of the press-fitting bracket 21 has a first receiving groove 211 for vertically placing the push rod 8, and the bottom wall of the first receiving groove 211 can abut against the bottom of the push rod 8. The top of the riveting bracket 22 has a second receiving groove 221 adapted to the balance valve core 9, and the bottom wall of the second receiving groove 221 can abut against the bottom of the balance valve core 9. A third receiving groove 222 for the push rod 8 to extend into is formed on the bottom wall of the second receiving groove 221.

[0039] Reference Figure 3 A pressure block 3 is vertically slidable below the support 11. A second driving member 13 is provided on the support 11 to drive the pressure block 3 to slide. In this embodiment, the second driving member 13 is also an electric push rod. The second driving member 13 is fixedly connected to the top of the support 11, and its output end passes through the support 11 and is fixedly connected to the pressure block 3. The second driving member 13 is electrically connected to the processor, and its movement is controlled by the processor. A pressing table 31 and a riveting table 32 are fixedly provided at the bottom of the pressure block 3. The pressing table 31 and the riveting table 32 are arranged at intervals along the sliding direction of the slide 2, with the pressing table 31 located directly above the pressing support 21.

[0040] Reference Figure 3 and Figure 5The bottom of the pressing table 31 is equipped with a loading assembly 4, which is used to load or release the balance valve core 9. Specifically, the loading assembly 4 includes an electric suction cup 42 and a positioning member 41. The positioning member 41 is fixedly connected to the pressing table 31, and the bottom of the positioning member 41 has a positioning groove 411 adapted to the balance valve core 9. The top wall of the positioning groove 411 can abut against the top of the balance valve core 9. The electric suction cup 42 is embedded in the positioning member 41 and is fixedly connected to the pressing table 31 through the positioning member 41. The electric suction cup 42 can hold the balance valve core 9. The electric suction cup 42 is electrically connected to the processor, and the movement of the electric suction cup 42 is controlled by the processor. The bottom of the riveting table 32 is fixedly equipped with a riveting head 321 for riveting the balance valve core 9.

[0041] Reference Figure 2 The deflection assembly 5 includes a rack 51 and a gear 52. The rack 51 is fixedly connected to the worktable 1 and extends along the sliding direction of the slide block 2. The gear 52 is rotatably connected to the rotating frame 23. The gear 52 is coaxial and fixedly connected to the press support 21. The gear 52 and the rack 51 mesh with each other.

[0042] Reference Figure 2 and Figure 6 A loading platform 6 is fixedly installed on the workbench 1. A pre-loading groove 61, penetrating both side walls, is opened on the top of the loading platform 6 along the sliding direction of the slide block 2. The pre-loading groove 61 allows the push rod 8 to be horizontally inserted. The first receiving groove 211 can be deflected by the pressing support 21 to face the pre-loading groove 61 at the end near the slide block 2. Specifically, as the slide block 2 moves, the gear 52 meshes with the rack 51, causing the first receiving groove 211 to deflect. When the riveting platform 32 is directly above the riveting support 22, the first receiving groove 211 deflects to face the pre-loading groove 61 at the end near the slide block 2.

[0043] Reference Figure 2 and Figure 6 A push block 611 is slidably disposed within the pre-loading trough 61 at the end furthest from the slide block 2, along the sliding direction of the slide block 2. The push block 611 can abut against the push rod 8 within the pre-loading trough 61. The loading platform 6 is also provided with a third driving member 62 for driving the push block 611 to slide. In this embodiment, the third driving member 62 is also an electric push rod, and the third driving member 62 is fixedly connected to the loading platform 6. The output end of the third driving member 62 is fixedly connected to the push block 611.

[0044] Reference Figure 2 and Figure 6The valve push rod 8 pressing device also includes a through-beam sensor, which includes a transmitter 71 and a receiver 72. The receiver 72 is fixed and embedded in the loading platform 6 on the side near the slide 2, and the transmitter 71 is fixed and embedded in the top of the pressing support 21. When the first receiving groove 211 is facing the pre-loading groove 61 at the end near the slide 2, the transmitter 71 is facing the receiver 72. The through-beam sensor and the third driving member 62 are electrically connected through a processor. Specifically, when the receiver 72 receives a signal from the transmitter, the processor controls the third driving member 62 to perform a reciprocating motion, pushing the push rod 8 in the pre-loading groove 61 into the first receiving groove 211.

[0045] Reference Figure 2 and Figure 6 The top of the loading platform 6 is inclined and fixed with a loading ramp 63. The bottom end of the loading ramp 63 faces the opening of the pre-loading trough 61. The loading ramp 63 allows the push rod 8 to roll into the pre-loading trough 61.

[0046] The implementation principle of the valve push rod 8 pressing device in this embodiment is as follows: Before assembling the push rod 8 and the balance valve core 9, the operator first places several push rods 8 sequentially on the loading ramp 63. The push rod 8 at the lowest point on the loading ramp 63 rolls down into the pre-loading trough 61 under gravity. The operator vertically inserts one push rod 8 into the first receiving groove 211 of the pressing support 21, so that the end of the push rod 8 with the chamfer 81 faces upward. The operator sends the balance valve core 9 into the positioning groove 411, and the electric suction cup 42 sucks the balance valve core 9 to the bottom of the pressing table 31. At this time, the connection hole 91 of the push rod 8 and the balance valve core 9 are aligned.

[0047] After the device is started, the processor controls the second drive unit 13, the first drive unit 12, and the electric suction cup 42 to move automatically. First, the pressure block 3 moves downward for the first time, and the pressing table 31 drives the balance valve core 9 to press down, so that the push rod 8 passes through the connecting hole 91 of the balance valve core 9 and forms an interference fit. Then, the pressure block 3 moves upward, lifting the balance valve core 9 and the push rod 8 together. Next, the slide 2 moves for the first time, so that the riveting support 22 is directly below the pressing table 31.

[0048] Afterwards, the pressure block 3 descends for the second time, and the pressing table 31 sends the balance valve core 9 into the second receiving groove 221 of the riveting support 22, while the push rod 8 enters the third receiving groove 222. At the same time, the balance valve core 9 is released. Subsequently, the pressure block 3 moves upward. After the pressure block 3 stabilizes, the electric suction cup 42 resumes suction, and the operator adds a new balance valve core 9 to the positioning groove 411. While adding the new balance valve core 9, the slide 2 moves for the second time, positioning the riveting table 32 directly above the riveting support 22.

[0049] During the movement of the slide 2, the gear 52 meshes with the rack 51, and the first receiving groove 211 deflects with the pressing support 21 to face the pre-loading groove 61 near the end of the slide 2. At this time, the transmitting end 71 of the through-beam sensor is aligned with the receiving end 72, and the signal emitted by the transmitting end 71 is received by the receiving end 72. The through-beam sensor sends a command to the third driving component 62 through the processor. The third driving component 62 starts, driving the push block 611 to perform a reciprocating motion, pushing the push rod 8 in the pre-loading groove 61 into the first receiving groove 211, completing the preparation for feeding the new push rod 8. After the push block 611 is reset, the pre-loading groove 61 is emptied, and the push rod 8 on the feeding ramp 63 rolls into the pre-loading groove 61.

[0050] After the riveting table 32 is positioned directly above the riveting support 22, the pressure block 3 moves downward for the third time. The riveting block 3 drives the riveting head 321 to rivet the balance valve core 9. After riveting, the end of the connecting hole 91 deforms towards the chamfer 81 of the push rod 8 and covers the chamfer 81. Then, the pressure block 3 moves upward, and the assembled push rod 8 and balance valve core 9 remain on the riveting table 32, which the operator can directly remove. The riveting action of the balance valve core 9 is performed simultaneously with the supplementary action of the push rod 8 in the first receiving groove 211, improving assembly efficiency. Finally, the slide 2 moves for the third time to reset, so that the pressing support 21 is reset below the pressing table 31. During this process, the gear 52 meshes with the rack 51, causing the pressing support 21 to deflect in the opposite direction. The new push rod 8 in the pre-loading groove 61 is vertically upward and directly aligned with the connecting hole of the new balance valve core 9 that has been added in the positioning groove 411, thus completing one work cycle. This improves the assembly efficiency of push rod 8 and balance valve core 9 and reduces manual operation steps.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
