Description

Technical Field

[0001] This utility model relates to the field of pressure relief valve assembly technology, specifically a pressure relief valve assembly device based on disc repositioning. Background Technology

[0002] A pressure relief valve is a safety component installed in a pneumatic or hydraulic system, primarily used to regulate system pressure and prevent it from exceeding a preset value. When the internal system pressure reaches the set value, the pressure relief valve automatically opens, releasing excess fluid to protect equipment and personnel. Pressure relief valves are widely used in industries such as petroleum, natural gas, and chemical processing, and are crucial components for ensuring system safety.

[0003] In the field of pressure relief valve manufacturing, the assembly process is complex and requires extremely high precision. However, existing assembly technologies are often limited by poor connection and inaccurate positioning of components during transport and assembly. While traditional assembly lines can transport components via conveyor belts, their connection to the assembly stations is not tight. When components arrive at the assembly station, the continuous operation of the conveyor belt can cause a mismatch between the component's speed and position and the assembly requirements, leading to frequent adjustments by assembly personnel and delays in the assembly process. Furthermore, assembly methods using vibratory feeders suffer from inaccurate positioning due to the oscillation and vibration of the vibratory feeder's output track, causing components to shift or tilt upon entering the assembly station, impacting overall assembly quality and efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a pressure relief valve assembly device based on disc-type transposition to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pressure relief valve assembly device based on disc-type repositioning includes an operating table and a fixed workstation fixedly installed on the operating table. A turntable is installed on the operating table via a drive mechanism. When the drive mechanism is running, the turntable will repeatedly rotate a certain angle and then remain stationary.

[0007] The turntable is provided with a clamping assembly, and there are multiple clamping assemblies. The multiple clamping assemblies are evenly distributed along the circumference and are used to clamp multiple parts to be assembled. The multiple clamping assemblies will pass through the fixed station in sequence under the drive of the turntable, and remain stationary for a period of time when they reach the fixed station.

[0008] An unlocking lever is provided on the operating table. The unlocking lever is located near the fixed workstation and is adapted to multiple clamping components. When the clamping components begin to approach the fixed workstation, the unlocking lever will cooperate with the clamping components, causing the clamping components to gradually loosen the parts to be assembled. When the clamping components fully reach the fixed workstation, the parts to be assembled will be completely loosened and fall into the pressure relief valve base fixed on the fixed workstation.

[0009] As a further embodiment of this utility model:

[0010] The drive mechanism includes a rotating shaft and a rotating rod, both of which are vertically rotatably mounted on the operating table.

[0011] The turntable is coaxially fixed on the rotating shaft, and a reduction motor is fixedly installed on the operating table. The output end of the reduction motor is coaxially fixedly connected to one end of the rotating rod.

[0012] As a further improvement of this utility model:

[0013] A drive disc is coaxially fixed on the rotating rod, and a driven disc is coaxially fixed on the rotating shaft. The drive disc and the driven disc cooperate with each other.

[0014] When the driving disk rotates, the driven disk will repeatedly rotate a certain angle and then remain stationary.

[0015] As a further improvement of this utility model:

[0016] The clamping assembly includes a support base, a cover plate, and a ring, with the support base fixedly mounted on the turntable.

[0017] The cover plate is fixedly mounted on the support base, and the ring is rotatably mounted between the support base and the cover plate.

[0018] As a further improvement of this utility model:

[0019] The bottom of the cover plate is provided with a sliding groove along its radial direction. There are multiple sliding grooves and they are evenly distributed along the circumference. A clamping rod is slidably disposed in each of the multiple sliding grooves.

[0020] The top of the cover plate has a limiting groove along its radial direction. There are multiple limiting grooves evenly distributed along the circumference. The ring has an arc-shaped groove, which is also evenly distributed along the circumference. Each of the clamping rods has a sliding column fixedly installed on it. The sliding columns are located in the limiting grooves and the arc-shaped grooves respectively and slide in cooperation with each other. When the ring rotates, the clamping rods will either come together or separate.

[0021] As a further improvement of this utility model:

[0022] A sealing plate is fixedly installed on the top of the cover plate, and a guide ring is fixedly installed on the sealing plate. The bottom of the guide ring is in contact with the top surface of the plurality of clamping rods.

[0023] The circumference of the ring is fixedly provided with a protruding post, and a vertical post is fixedly provided on the protruding post. A nail post is fixedly provided on the support base. The vertical post and the nail post are connected by a hook spring. Under the action of the hook spring, the ring always has the tendency to bring the multiple clamping rods together.

[0024] As a further improvement of this utility model:

[0025] The clamping rod has a groove at one end near the center of the ring, and a T-shaped rod is slidably disposed in the groove;

[0026] An arc-shaped plate is fixedly installed at one end of the T-shaped rod near the center of the ring. A helical spring is sleeved on the outer wall of the T-shaped rod. The two ends of the helical spring abut against the arc-shaped plate and the clamping rod, respectively, so as to drive the arc-shaped plate to always have a tendency to move away from the clamping rod.

[0027] Compared with the prior art, the beneficial effects of this utility model are:

[0028] The drive mechanism rotates the turntable to a certain angle and then keeps it stationary. Combined with the even layout of the clamping components, the orderly conveying and assembly of parts is achieved. When the turntable drives the clamping components to pass through the fixed workstations in sequence, the unlocking rod cooperates with the clamping components to release the parts and let them fall into the pressure relief valve base, reducing manual intervention and improving assembly speed and production efficiency.

[0029] The clamping components are evenly distributed along the circumference and pass through fixed stations in sequence, ensuring the precise positioning of the parts. The precise cooperation of the unlocking rod enables the parts to be accurately released to the designated position, thereby improving the assembly accuracy of the pressure relief valve.

[0030] The alternation of rotation and stillness of the turntable allows each assembly step to be completed at a fixed station within sufficient time, which is conducive to the automation and standardization of the production process and reduces waiting time and logistics links in the production process.

[0031] The intermittent operation of the turntable and the stable clamping of the clamping components make the equipment run more smoothly, reducing vibration and wear that may be caused by frequent starts and stops or rapid movements, and improving the service life and operational stability of the equipment.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Furthermore, the elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0042] Please see Figures 1-7 In this embodiment of the utility model, a pressure relief valve assembly device based on disc repositioning includes an operating table 1 and a fixed workstation 2 fixedly installed on the operating table 1. A turntable 3 is installed on the operating table 1 through a drive mechanism. When the drive mechanism is running, the turntable 3 will repeatedly rotate a certain angle and then remain stationary.

[0043] The turntable 3 is provided with a clamping assembly. The clamping assembly is configured in multiple ways and is evenly distributed along the circumference. It is used to clamp multiple parts to be assembled. The multiple clamping assemblies will pass through the fixed station 2 in sequence under the drive of the turntable 3, and remain stationary for a period of time when they reach the fixed station 2.

[0044] The operating table 1 is equipped with an unlocking lever 4, which is located near the fixed workstation 2. The unlocking lever 4 is adapted to multiple clamping components. When the clamping components begin to approach the fixed workstation 2, the unlocking lever 4 will cooperate with the clamping components, causing the clamping components to gradually loosen the parts to be assembled. When the clamping components fully reach the fixed workstation 2, the parts to be assembled will be completely loosened and fall into the pressure relief valve base fixed on the fixed workstation 2.

[0045] In this scheme, when the equipment is running, the drive mechanism starts, causing the turntable 3 to rotate at a certain angle and then come to a stop. Multiple clamping components evenly distributed along the circumference on the turntable 3 rotate accordingly and pass through the fixed station 2 in sequence. When the clamping components approach the fixed station 2 under the drive of the turntable 3, the unlocking rod 4 near that location cooperates with the clamping components to gradually loosen the parts. When the clamping components have completely reached the fixed station 2 and remain stationary, the parts are completely loosened and fall into the pressure relief valve base fixed on the fixed station 2, completing the assembly step.

[0046] As a further embodiment of this utility model, the driving mechanism includes a rotating shaft 5 and a rotating rod 6, both of which are vertically rotatably mounted on the operating table 1.

[0047] The turntable 3 is coaxially fixed on the rotating shaft 5, and a reduction motor 9 is fixedly installed on the operating table 1. The output end of the reduction motor 9 is coaxially fixedly connected to one end of the rotating rod 6.

[0048] A drive disk 7 is coaxially fixed on the rotating rod 6, and a driven disk 8 is coaxially fixed on the rotating shaft 5. The drive disk 7 and the driven disk 8 cooperate with each other.

[0049] When the driving disk 7 rotates, the driven disk 8 will repeatedly rotate a certain angle and then remain stationary.

[0050] In this embodiment, when the geared motor 9 starts, its output end drives the rotating rod 6 to rotate, and the driving disk 7 on the rotating rod 6 rotates accordingly; the driving disk 7 and the driven disk 8 cooperate with each other, so that the driven disk 8 drives the rotating shaft 5 to rotate a certain angle first, and then remain stationary; the rotating disk 3 is fixed on the rotating shaft 5, so the rotating disk 3 repeats the action of first rotating a certain angle and then remaining stationary with the rotating shaft 5.

[0051] As a further embodiment of this utility model, the clamping assembly includes a support base 10, a cover plate 11, and a ring 12, wherein the support base 10 is fixedly mounted on the turntable 3;

[0052] The cover plate 11 is fixedly mounted on the support base 10, and the ring 12 is rotatably mounted between the support base 10 and the cover plate 11;

[0053] The bottom of the cover plate 11 is provided with a sliding groove 1101 along its radial direction. There are multiple sliding grooves 1101 and they are evenly distributed along the circumference. A clamping rod 13 is slidably arranged in each of the multiple sliding grooves 1101.

[0054] The top of the cover plate 11 has a limiting groove 1102 radially formed, and the number of limiting grooves 1102 is evenly distributed along the circumference. The ring 12 has an arc-shaped groove 1201, and the number of arc-shaped grooves 1201 is evenly distributed along the circumference. Each of the multiple clamping rods 13 is fixedly provided with a sliding column 14, and the multiple sliding columns 14 are respectively located in the multiple limiting grooves 1102 and the multiple arc-shaped grooves 1201 and slide in cooperation with each other. When the ring 12 rotates, the multiple clamping rods 13 will either come together or separate from each other.

[0055] A sealing plate 15 is fixedly provided on the top of the cover plate 11, and a guide ring 16 is fixedly provided on the sealing plate 15. The bottom of the guide ring 16 is in contact with the top surface of the plurality of clamping rods 13.

[0056] The circumferential surface of the ring 12 is fixedly provided with a protruding post 17, and a vertical rod 18 is fixedly provided on the protruding post 17. A nail post 19 is fixedly provided on the support base 10. The vertical rod 18 and the nail post 19 are connected by a hook spring 20. Under the action of the hook spring 20, the ring 12 always has the tendency to bring the multiple clamping rods 13 together.

[0057] The clamping rod 13 has a groove 1301 at one end near the center of the ring 12, and a T-shaped rod 21 is slidably disposed in the groove 1301.

[0058] An arc-shaped plate 22 is fixedly installed at one end of the T-shaped rod 21 near the center of the ring 12. A helical spring 23 is sleeved on the outer wall of the T-shaped rod 21. The two ends of the helical spring 23 abut against the arc-shaped plate 22 and the clamping rod 13 respectively, so as to drive the arc-shaped plate 22 to always have a tendency to move away from the clamping rod 13.

[0059] In this embodiment, the rotation of the ring 12 is the key action in the operation of the clamping assembly. Through the sliding engagement of the sliding column 14 within the limiting groove 1102 and the arc-shaped groove 1201, it drives multiple clamping rods 13 to converge or separate, achieving clamping and releasing of the accessory. When no external force is applied, the hook spring 20, through connecting the upright 18 and the nail post 19, causes the ring 12 to drive the multiple clamping rods 13 to converge, ensuring that the accessory is always clamped by the multiple clamping rods 13. When the turntable 3 drives the ring 12 to revolve through the support base 10 and the cover plate 11, when the protrusion 17 fixed on the ring 12 abuts against the unlocking rod 4 fixed on the operating table 1, the protrusion 17 will drive the ring 12 to overcome the tension of the hook spring 20, thus... The ring 12 rotates in the opposite direction, causing the multiple clamping rods 13 to separate from each other. When the support base 10 accurately reaches the fixed position 2, the multiple clamping rods 13 will drive the multiple arc plates 22 to separate from the parts. The T-shaped rod 21 slides in the groove 1301 of the clamping rod 13, and the helical spring 23 drives the arc plate 22 away from the clamping rod 13 to further adapt to the shape of the parts and ensure stable clamping. During the process of the multiple clamping rods 13 separating from each other, the parts are still clamped due to the interaction between the helical spring 23 and the arc plate 22. The parts are completely released when the support base 10 is aligned with the fixed position 2. The bottom of the guide ring 16 is in contact with the top surface of the clamping rod 13, which restricts the upward movement of the clamping rod 13 and ensures the stability of the clamping assembly.
