Description

Technical Field

[0001] This application relates to the field of valve assembly, and in particular to a valve body sealing ring assembly device and valve assembly machine. Background Technology

[0002] Valves are fundamental components used to control fluids; they belong to the actuator category and are not limited to hydraulic or pneumatic applications. They are primarily used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Different valves play different roles in different control systems; common types include check valves, mounting valves, directional control valves, and speed regulating valves.

[0003] When using a valve body, it is necessary to ensure its sealing. Therefore, a sealing ring is installed in the valve body to prevent sealing between adjacent components. For example... Figure 1 and Figure 2 The diagram shows a valve body structure, in which the valve body 5 has a connecting section 51, and two sealing grooves 52 for installing inner sealing rings are spaced apart on the connecting section 51 inside the valve body. However, during the assembly of the sealing rings, they need to be inserted through the opening of the connecting section 51 of the valve body 5. This makes assembling the subsequent sealing ring more difficult and prone to accidentally getting stuck in the sealing groove 52 of the preceding ring, affecting the assembly effect. Summary of the Invention

[0004] To improve the stability of subsequent sealing ring assembly, this application provides a valve body sealing ring assembly device and a valve assembly machine.

[0005] This application provides a valve body sealing ring assembly device, which adopts the following technical solution:

[0006] A valve body sealing ring assembly device includes: a positioning mechanism for positioning the valve body and making both ends of the valve body open to the outside; a supply mechanism including a conveying channel and a supply component for sequentially feeding the sealing rings to be assembled into the conveying channel; a loading mechanism disposed at the end of the conveying channel for feeding the sealing rings onto the valve body; and an assembly mechanism including a push rod and a mating rod, wherein the push rod and the mating rod are respectively inserted into the valve body from both ends and feed the sealing rings into corresponding sealing grooves; wherein the loading mechanism includes two symmetrically arranged grippers, and the two grippers on opposite sides... The surface is provided with clamping grooves. When the two clamping jaws are closed, the two clamping grooves are joined to form a joint groove with a width smaller than the diameter of the sealing ring under normal conditions. The feeding mechanism also includes a pusher that pushes the sealing ring into the joint groove, a drive that moves the two clamping jaws to the top of the valve body and aligns the joint groove with the opening on one side of the valve body, a pressure rod for inserting into the joint groove and pushing the sealing ring into the valve body, and a cone rod controlled by a power member that is inserted into the valve body from the opposite direction of the pressure rod. The cone rod has a cone-shaped head, and the cone tail end of the cone head is flush with the corresponding sealing groove.

[0007] By adopting the above technical solution, the sealing ring is deformed by clamping the gripper. At this time, the width of the sealing ring is smaller than the opening of the valve body. Then, the sealing ring is sent into the valve body by the pressure rod. Since the top of the cone rod is a cone, the sealing ring will be skewed when it contacts the cone. Since the tail end of the cone is parallel to the sealing groove, one end of the sealing ring will abut in the corresponding sealing groove. Then, the push rod and the mating rod extend from both ends of the valve body to assemble the sealing ring into place.

[0008] Optionally, a transfer seat is provided at the end of the conveying channel. The transfer seat has a transfer groove that communicates with the conveying channel. The width of the transfer groove is smaller than the diameter of the sealing ring. The pusher first sends the sealing ring into the transfer groove and then sends the sealing ring into the connecting groove.

[0009] By adopting the above technical solution, the sealing ring is first sent to the transfer seat for extrusion and deformation, which facilitates the subsequent delivery of the sealing ring to the combined groove.

[0010] Optionally, the transfer seat has a storage groove for placing the foremost sealing ring, the width of the storage groove is not less than the diameter of the sealing ring, and the storage groove is connected to the transfer groove.

[0011] By adopting the above technical solution, the sealing rings are continuously and sequentially fed out by the supply mechanism. Due to the presence of the storage groove on the transfer seat, the sealing rings can serve as a transition, and they will first stay in the storage groove, which facilitates the subsequent pusher to push the sealing rings into the transfer groove.

[0012] Optionally, a guide portion is provided at one end of the transfer trough near the storage trough, and the width of the guide portion gradually decreases from the direction of the storage trough to the direction of the transfer trough.

[0013] By adopting the above technical solution, the deformation of the sealing ring can be guided, making it easier for the sealing ring to be sent into the transfer groove.

[0014] Optionally, the push-in component includes a vertical plate, on which a first control component is connected to move the vertical plate along the direction of the transfer groove, and a second control component is connected to move the vertical plate into or out of the sealing ring. The transfer seat is also provided with a through groove that communicates with the transfer groove and is used for the vertical plate to pass through.

[0015] By adopting the above technical solution, the vertical plate is inserted into the sealing ring located in the storage groove by the second control component, and then enters the transfer groove along with the sealing ring under the drive of the first control component. The groove setting does not affect the normal passage of the vertical plate. During the process of sending it into the combined groove, a gap is first left between the two jaws for the vertical plate to pass through, that is, the two jaws are not in the closed state at first. After the sealing ring is sent into the gap between the two jaws, the second control component drives the vertical plate to disengage from the sealing ring and move it out of the middle position of the two jaws. Then the two jaws close and re-form the combined groove to deform the sealing ring again.

[0016] Optionally, the driving component is a rotary cylinder, which includes a cylinder body and a rotatable rotating disk. A clamping driving component for controlling the gripper to clamp or retract is fixed on the rotating disk. The rotating disk has a first working position and a second working position. When the rotating disk is in the first working position, the connecting groove and the transfer groove are aligned. When the rotating disk is in the second working position, the connecting groove is aligned with the valve body. The pressure rod is used to insert into the connecting groove to push the sealing ring into the valve body.

[0017] By adopting the above technical solution, when the rotating disk is in the first working position, the combined groove and the transfer groove are aligned, which facilitates the pusher to send the sealing ring into the combined groove; when the rotating disk is in the second working position, the combined groove and the valve body are aligned, which facilitates the pressure rod to push the sealing ring into the valve body.

[0018] Optionally, the pressure rod is connected to a pressure rod drive component that drives the pressure rod to move toward the valve body. The pressure rod drive component is fixedly connected to the cylinder body of the rotary cylinder. A cylinder body drive component that drives the cylinder body to move along the conveying channel is connected to the cylinder body of the rotary cylinder.

[0019] By adopting the above technical solution, the cylinder drive component can maintain the relative position of the pressure rod and the cylinder during the process of moving the cylinder.

[0020] Secondly, this application also provides a valve assembly machine, including the aforementioned valve body sealing ring assembly device.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] The pressure rod and the cone rod work together to first tilt the sealing ring into the valve body, so that one end of the sealing ring is stuck in the corresponding sealing groove. Then the push rod and the mating rod push the sealing ring into place. Attached Figure Description

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0036] This application discloses a valve body sealing ring assembly device for assembling a valve body sealing ring. Figure 1 and attached Figure 2 The sealing ring is assembled in the sealing groove 52 inside the valve body 5. (Refer to...) Figure 3 The valve body sealing ring assembly device includes a positioning mechanism 1 for positioning the valve body 5, a supply mechanism 2 for sequentially feeding the sealing rings, a feeding mechanism 3 for feeding the sealing rings onto the valve body 5, and an assembly mechanism 4 for assembling the sealing rings into the corresponding sealing grooves 52.

[0037] Specifically, refer to Figure 4 and Figure 5 The positioning mechanism 1 includes a positioning platform 11 for placing the valve body 5. The positioning platform 11 has a mounting hole 111 for inserting one end of the valve body 5. The mounting hole 111 communicates with the opening at one end of the valve body 5. The valve body 5 is inserted into the mounting hole 111, and the connecting section 51 of the valve body 5 is larger than the diameter of the mounting hole 111 and located outside the mounting hole 111. The positioning mechanism 1 also includes a positioning claw 112, which clamps around the connecting section 51 to the outside, thereby restricting the movement of the valve body 5 during assembly. Simultaneously, the positioning claw 112 does not close the opening of the valve body 5 on one side of the connecting section 51, thus maintaining communication between the openings at both ends of the valve body 5 and the outside.

[0038] Reference Figure 6 The supply mechanism 2 includes a conveying channel 21 and a supply component 22 that sequentially feeds the sealing rings to be assembled into the conveying channel 21. In this embodiment, the supply component 22 is a vibrating feeding screen, which feeds the sealing rings out sequentially through vibration. Of course, other embodiments may also use other forms that can feed the sealing rings out one by one.

[0039] Reference Figure 6 and Figure 7 The feeding mechanism 3 includes two grippers 31 for holding the sealing ring and a pressure rod 32 for feeding the sealing ring from the grippers 31 into the valve body 5. A gripping groove 311 is formed on the opposite side of the two grippers 31. When the two gripping grooves 311 are closed, they form a combined groove with a width smaller than the diameter of the sealing ring in its normal state. The grippers 31 deform the sealing ring, and the deformed sealing ring... Figure 8 As shown in the figure, at this time the width of the sealing ring is smaller than the diameter of the opening of the valve body 5, and then the pressure rod 32 is inserted into the combined groove to push the sealing ring into the valve body 5.

[0040] Furthermore, refer to Figure 6 and Figure 7 At the end of the conveying channel 21, a transfer seat 33 is provided. On the side of the transfer seat 33 facing the conveying channel 21, a storage groove 331 is provided for placing the foremost sealing ring. The width of the storage groove 331 is slightly larger than the diameter of the sealing ring. After the foremost sealing ring enters the storage groove 331, subsequent sealing rings cannot be conveyed forward. The transfer seat 33 also has a transfer groove 332 communicating with the storage groove 331. The width of the transfer groove 332 is smaller than the diameter of the sealing ring in its normal state. At the same time, a guide portion is provided at the end of the transfer groove 332 near the storage groove 331, and the width of the guide portion gradually decreases from the direction of the storage groove 331 to the direction of the transfer groove 332.

[0041] Reference Figure 6 and Figure 7 The feeding mechanism 3 also includes a pusher 34 that pushes the sealing ring into the transfer groove 332 and then into the combined groove. The pusher 34 includes a vertical plate 341, which is connected to a first control member 342 that moves itself along the transfer groove 332, and a second control member 343 that moves it into or out of the sealing ring. The second control member 343 controls the vertical plate 341 to insert into the sealing ring located in the storage groove 331, and then the first control member 342 moves the vertical plate 341 and the sealing ring towards the conveying groove. In order not to affect the movement of the vertical plate 341, the conveying seat is further provided with a through groove 333 that communicates with the conveying groove and is used for the vertical plate 341 to pass through.

[0042] Reference Figure 6 and Figure 7The two grippers 31 are initially positioned at the rear end of the transfer seat 33, and at this time, the two grippers 31 are not in the closed state. In this state, the width of the joint groove formed between the two grippers 31 is consistent with and aligned with the transfer groove 332. The gap between the two grippers 31 allows the vertical plate 341 to pass through. When the vertical plate 341 drives the sealing ring into the space between the two grippers 31, the second control member 343 drives the vertical plate 341 away from the space between the two grippers 31. At this time, the sealing ring will be restricted by the clamping groove 311 and will not detach with the vertical plate 341. Subsequently, the two grippers 31 close and further compress and deform the sealing ring, so that the width of the sealing ring at this time is smaller than the opening size of the valve body 5.

[0043] Furthermore, refer to Figure 7 The gripper 31 is also connected to a drive component 35, which moves the gripper 31 above the valve body 5 and aligns the connecting groove with the opening of the valve body 5. The drive component 35 is a rotary cylinder, which includes a cylinder body 351 and a rotatable rotating disk 352. The gripper 31 is controlled by the clamping drive component 312, which is fixed on the rotating disk 352. In this application, the clamping drive component 312 is a pneumatic drive source. By fixing the clamping drive component 312 on the rotating disk 352, the gripper 31 and the rotating disk 352 can rotate together.

[0044] The rotating disk 352 has a first working position and a second working position. When the rotating disk 352 is in the first working position, the gripper 31 is located at the rear end of the transfer seat 33 to receive the sealing ring; when the rotating disk 352 is in the second working position, the combined groove of the gripper 31 is aligned with the opening of the valve body 5.

[0045] Reference Figure 7 The pressure rod 32 is adapted to the combined groove in the closed state. A pressure rod drive component 321 is connected to the pressure rod 32, which moves the pressure rod 32 towards the valve body 5. The pressure rod drive component 321 is fixedly connected to the cylinder body 351 of the rotary cylinder. A cylinder drive component is also connected to the rotary cylinder, which moves the cylinder body 351 along the conveying channel 21. The cylinder drive component is fixed to a fixed plate on the side of the conveying channel 21. When the rotating disk 352 is in the first working position, the combined groove is in a horizontal state. At this time, after the gripper 31 clamps the sealing ring, the cylinder drive component can drive the rotary cylinder to move it above the positioned valve body 5. Then, the rotating disk 352 rotates to the second working position, at which time the combined groove is in a vertical state and connected to the opening of the valve body 5.

[0046] Reference Figure 9To prevent the feeding mechanism 3 from delivering the sealing ring into the preceding sealing groove 52, and to ensure that the feeding mechanism 3 can deliver the sealing ring into the following sealing groove 52, the feeding mechanism 3 also includes a tapered rod 36 inserted into the valve body 5 from the bottom of the valve body 5. The tapered rod 36 has a tapered head 361, the tapered tail end of which is flush with the side wall of the following sealing groove 52 away from the preceding sealing groove 52. During the process of the pressure rod 32 delivering the sealing ring into the valve body 5, the sealing ring abuts against the tapered head 361. As the pressure rod 32 continues to press down, the sealing ring tilts and moves along the tapered surface, with one end stuck into the following sealing groove 52. At this time, the sealing ring is still in a tilted state. The tapered rod 36 is controlled by a power component to control the movement of the tapered rod 36. The power component can be a cylinder or a linear drive mechanism such as a gear and rack mechanism that can drive the tapered rod 36 to move vertically. After the sealing ring is delivered to the corresponding position, the power component drives the cone rod 36 to move out of the valve body 5. At this time, due to the elasticity of the sealing ring itself, the sealing ring will not fall out of the valve body 5.

[0047] Reference Figure 9 , Figure 10 and Figure 11 The assembly mechanism 4 includes a push rod 41 and a mating rod 42. The push rod 41 and the mating rod 42 are inserted into the valve body 5 from both ends of the valve body 5, respectively. The top of the push rod 41 is flush with the end of the rear sealing groove 52 that is away from the front sealing groove 52. The diameter of the mating rod 42 is the same as the inner diameter of the valve body 5. After the mating rod 42 is pressed down, it pushes the sealing ring into place.

[0048] It should be noted that both the push rod 41 and the mating rod 42 are connected to their respective power components. Furthermore, to avoid interference between the push rod 41 and the cone rod 36, the positioning mechanism 1 can be mounted on a turntable. After the sealing ring is in place, the turntable rotates to another position, at which point the push rod 41 and the mating rod 42 assemble the sealing ring. Alternatively, in other embodiments, the cone rod 36 can be moved away from the bottom of the valve body 5 first, and then the push rod 41 can be pushed upwards into the valve body 5.

[0049] The implementation principle of the valve body sealing ring assembly device in this application is as follows:

[0050] The sealing rings are sequentially fed into the conveying channel 3. The feeding mechanism 3 moves the delivered sealing rings into the valve body 5. When the cone rod 36 and the pressure rod 32 cooperate, the sealing ring is in an inclined state and one end is stuck in the corresponding sealing groove 52. Then, the sealing ring is assembled into place by the top rod 41 and the cooperating rod 42.

[0051] In addition, this application also discloses a valve assembly machine that assembles the sealing ring inside the valve body 5 using the aforementioned valve body sealing ring assembly device.

[0052] 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.
