[0002] A pressure reducer is a device used to reduce high-pressure gas to the required low pressure and maintain a stable output. Its structural design must take into account pressure regulation, sealing performance, and safety protection. The assembly process of the pressure reducer must be combined with its structural characteristics, such as the main body, valve, pressure gauge, and regulating device. At present, during the operation of the pressure reducer assembly machine, the corresponding parts are accurately assembled onto the valve body one by one in a predetermined order. In this series of assembly steps, it is particularly important to use specially designed tightening tools that meet specific shape requirements to ensure that the pressure gauge can be firmly installed on the valve body. However, in the actual assembly process of the pressure gauge, due to the lack of an effective positioning mechanism, the position of the pressure gauge is difficult to accurately control. This insufficient positioning problem not only makes the assembly process of the pressure gauge complicated and time-consuming, but also makes it inconvenient for the operator to directly take the assembled pressure reducer after completing the assembly of the pressure gauge. This inconvenience directly affects the overall work efficiency of the pressure reducer assembly, prolongs the assembly cycle, and reduces the smoothness and production efficiency of the production line. Chinese patent document announcement number: "CN104551648B A pressure reducer assembly machine and its assembly method, belonging to the field of mechanical technology. It solves the problems of low efficiency and high labor intensity in the existing pressure reducer assembly. The pressure reducer assembly machine includes a base plate, a positioning seat installed on the base plate and a clamping mechanism, a valve body is placed on the positioning seat, and the clamping mechanism pushes the valve body to be positioned on the positioning seat.

[0021] The present invention will be described in further detail below with reference to the accompanying drawings.

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0023] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate directions or positions are based on the directions or positional relationships shown in the accompanying drawings, which are merely simplified descriptions for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the above terms should not be understood as limiting the present invention.

[0024] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0025] Example 1: Please refer to Figures 1-13 , a five-station pressure reducer assembly machine, including a workbench 1 and a frame 2 fixed on the workbench 1, and also including: a suspension 3 fixed on the workbench 1, a parts collection tray 4 fixed on the suspension 3, an installation box 6 fixed on the parts collection tray 4 through at least two frames 5, a plurality of parts collection boxes 7 are arranged in order in the installation box 6, an assembly unit 8 is provided on the workbench 1, and the assembly unit 8 is used to assemble parts on the valve body, and; a support frame 9 fixed on the workbench 1, an assembly unit 10 is provided on the support frame 9, and the assembly unit 10 is used to install the pressure gauge on the valve body, a plurality of universal wheels are installed at the bottom of the workbench 1 to facilitate pushing the workbench 1 for position transfer, and an inspection door is provided on the workbench 1 to facilitate staff to inspect the structural components in the workbench 1; Among them, the installation box 6 is fixed with a frame 65, and the frame 65 is fixed with a parts storage slot 66, and the parts storage slot 66 is located obliquely below the parts collection box 7. By adding the parts storage slot 66, the storage capacity can be greatly improved to store more types of assembly parts; It should be noted that the parts collection tray 4 is an important tool specially designed for storing various parts required for the assembly process. Five independent parts collection trays 4 are provided on the installation box 6. The main purpose is to store the core assembly parts in order according to different categories. Through this reasonable classification and storage method, not only can the various parts be kept in order, but it can also greatly facilitate the assemblers to quickly and accurately take the corresponding parts when needed, thereby completing the assembly work efficiently, reducing the error rate in the assembly process, and ensuring the assembly quality. It should also be noted that the corresponding parts are taken and the assembly unit 8 installs the parts on the valve body in sequence, which optimizes the assembly process of the pressure reducer, and the assembly unit 8 is suitable for different assembly tasks. After the valve body is assembled with other parts, the pressure gauge is installed on the valve body through the assembly unit 10, and the assembly work of the pressure gauge is completed efficiently. The positioning of the pressure gauge can be completed accurately, and after the assembly work is completed, the positioning can be smoothly released for easy taking.

[0026] Furthermore, the assembly unit 8 includes: a plurality of carriers 11 fixed in the workbench 1, a guide rail a12 fixed on the carrier 11, a sliding sleeve a13 slidably connected to the guide rail a12, a tightening machine 15 fixed to the sliding sleeve a13 via a support plate a14, a through hole a16 for the output end of the tightening machine 15 to pass through is opened on the workbench 1, a sleeve a17 is fixed to one end of the output shaft of the tightening machine 15, a mounting sleeve a18 is fixed on the carrier 11, a pneumatic push rod a19 is fixed on the mounting sleeve a18, and the output end of the pneumatic push rod a19 is fixed to the support plate a14. Among them, at least two guide rods 63 are fixed on the tightening machine 15, and a guide plate 64 is fixed on the support frame 9. The guide rods 63 and the guide plates 64 are slidably arranged. By adding the guide rods 63 and the guide plates 64 to the tightening machine 15, it not only effectively guides the tightening machine 15 during movement, avoiding deviation and shaking of the equipment during movement, but also further improves the stability of the tightening machine 15 during movement, ensuring the safety of operation and work efficiency; It should be noted that the sleeve a17 fixed on the output end of the tightening machine 15 is replaced according to the parts assembly requirements to achieve the operation of installing the parts on the valve body. This is a conventional setting in the field and will not be described in detail here. It should also be noted that the arrangement of the assembly unit 8 is particularly suitable for accurately and efficiently assembling various different components onto the valve body. This arrangement not only significantly improves the coordination and smoothness of the assembly process, but also effectively solves the inefficiency problem that is prevalent in the assembly process of traditional pressure reducers. The assembly process of the pressure reducer has been comprehensively improved and enhanced, making the entire assembly process more efficient and orderly, thereby greatly improving production efficiency and product quality. The principle of assembling parts on the valve body using the assembly unit 8 is as follows: by taking the parts from the parts collection tray 4 and the parts collection box 7, the corresponding parts are taken out and placed in the corresponding sleeves a17 in turn, and the push rod a of the cylinder 20 is driven to drive the tightening machine 15 to drive the sliding sleeve a13 to move on the guide rail a12, completing the position adjustment of the tightening machine 15, and the sleeve a17 is driven to rotate by the driving of the tightening machine 15.

[0027] Furthermore, the assembly unit 10 includes: a cylinder 20 fixed to the support frame 9, the output end of the cylinder 20 passes through the support frame 9, a rubber pressure pad 21 is fixed to the output end of the cylinder 20, a base plate 22 is fixed to the workbench 1, and a guide rail b23 is fixed to the base plate 22, a sliding sleeve b24 is slidably connected to the guide rail b23, a drive motor 26 is fixed to the sliding sleeve b24 through a support plate b25, a positioning mechanism 27 is provided at one end of the output shaft of the drive motor 26, and the positioning mechanism 27 is used to position the pressure gauge, a pneumatic push rod b29 is fixed to the base plate 22 through a mounting sleeve b28, the output end of the pneumatic push rod b29 is fixed to the support plate b25, and a sleeve b30 is rotatably connected to the workbench 1; A limit plate 48 is fixed on the base plate 22, fixed to the guide rail b23, and abutted against the sliding sleeve b24. The addition of the limit plate 48 can effectively and accurately limit the sliding sleeve b24, thereby preventing the sliding sleeve b24 from exceeding a predetermined range due to excessive movement during movement, thereby avoiding the undesirable situation of disconnection between the sliding sleeve b and the slide rail b. It should be noted that, through the provision of the assembly unit 10, the assembly of the valve body and the pressure gauge can be completed accurately and efficiently. During the assembly process, the method of applying pressure from directly above is adopted, which can effectively improve the stability and reliability of the pressure reducer assembly, not only avoiding the misalignment phenomenon that may occur during the assembly process, but also greatly improving the assembly quality and efficiency, ensuring the expected standards of the final product; The principle of using the assembly unit 10 to install the pressure gauge on the valve body is as follows: by placing the valve body on the sleeve b30, the pressure gauge is positioned by the positioning mechanism 27, and the driving motor 26 is driven by the pneumatic push rod b29, so that after the force is applied to the driving motor 26, the sleeve b24 moves on the guide rail b23. When it reaches the designated appropriate position, the pressure gauge is driven to rotate by the driving motor 26, and cooperates with the movement of the pneumatic push rod b29 to complete the tightening assembly of the pressure gauge.

[0028] Example 2: Please refer to Figure 11-13 This embodiment further explains the first embodiment, and the difference lies in a method for adjusting the angle of the sleeve b30.

[0029] Furthermore, the workbench 1 is provided with an adjustment component 49 adapted to the sleeve b30, and the adjustment component 49 includes: a turntable 50 is fixed on the sleeve b30, and a circular arc groove 51 is opened on the turntable 50, and a limiting rod 52 located in the circular arc groove 51 is fixed on the workbench 1, and the limiting rod 52 slides in the circular arc groove 51, thereby limiting the rotation angle of the turntable 50. Both sides of the circular arc groove 51 are provided with smooth circular arc surfaces. Through this sliding mechanism, the rotation angle of the turntable 50 is effectively and accurately limited. The two sides of the circular arc groove 51 are designed to be smooth circular arc surfaces, which can effectively prevent the turntable 50 from getting stuck or stagnating when it rotates to the extreme position, ensuring that the turntable 50 always maintains a smooth, smooth and stable operation state during the entire process of rotation and rotary motion; Among them, the workbench 1 is rotatably connected to a transmission shaft 53, a spur gear 54 is fixed to the transmission shaft 53, and a plurality of teeth 55 meshing with the spur gear 54 are fixed to the turntable 50. A mounting frame 56 is fixed to the workbench 1, and a main shaft 57 is rotatably connected to the mounting frame 56, a worm 58 is fixed to the main shaft 57, a worm wheel 59 meshing with the worm 58 is fixed to the transmission shaft 53, and a servo motor 60 is fixed to the workbench 1, and the output shaft of the servo motor 60 is coaxially fixed to the main shaft 57; It should be noted that the angle between the two barometers is 25°, and the maximum rotation angle of the turntable 50 is consistent with the angle between the two barometers. In addition, the self-locking function of the worm gear 59 and the worm 58 can prevent the sleeve b30 from rotating during assembly. It should also be noted that the setting of the adjustment component 49 is suitable for the assembly work requirements of two pressure gauges. After completing the assembly work of one pressure gauge, the angle of the sleeve b30 is adjusted and the valve body is rotated to the appropriate assembly position to facilitate the assembly of the other pressure gauge, which greatly improves the efficiency of the pressure gauge assembly work, effectively reduces the downtime, and ensures relative continuity during the assembly work of the pressure gauges. The principle of using the adjustment component 49 to adjust the angle of the sleeve b30 is as follows: the main shaft 57 is driven by the servo motor 60 to rotate synchronously, driving the worm 58 to rotate synchronously, and the meshing transmission effect between the worm 58 and the worm wheel 59 is used to cause the transmission shaft 53 to rotate synchronously, thereby driving the spur gear 54 to rotate synchronously, and the meshing transmission effect between the spur gear 54 and the teeth 55 is used to make the sleeve b30 rotate after being subjected to force.

[0030] Example 3: Please refer to Figures 8-10 This embodiment further illustrates other embodiments, the difference being a method of positioning the pressure gauge.

[0031] Furthermore, the positioning mechanism 27 includes: a mounting block 31 is fixed to one end of the output shaft of the driving motor 26, and at least two grooves 32 are provided on the mounting block 31. A rotating rod 33 located in the groove 32 is fixed on the mounting block 31, one of the rotating rods 33 is rotatably connected to a pressure plate 34, and the other rotating rod 33 is rotatably connected to a support plate 35. A plurality of mounting rods 36 are fixed to the mounting block 31, and both the support plate 35 and the pressure plate 34 are rotatably connected to a movable plate 38 through a rod body 37, and a slide groove 39 is provided on the movable plate 38. , the mounting rod 36 is located inside the slide groove 39, the movable plate 38 is rotatably connected to the guide rod 40, the drive motor 26 is fixed with a cover plate 41, the cover plate 41 is fixed with an annular guide groove 42, and the annular guide groove 42 is rotatably connected to two electric push rods 44 through a rotating ring 43, the output end of the electric push rod 44 is fixed with a transmission plate 45, the transmission plate 45 is provided with a guide groove 46, and the guide rod 40 is located inside the guide groove 46, the output shaft of the drive motor 26 is fixed with a loading rod 47, and the other end of the loading rod 47 is fixed to the electric push rod 44; The support plate 35 is provided with a slot 61 for the pressure gauge to pass through, and a rubber gasket 62 is fixed to the pressure plate 34. The rubber gasket 62 is located directly above the support plate 35. The slot 61 ensures that the pressure gauge is stably restrained and stuck in the support plate 35. The addition of the rubber gasket 62 effectively and stably presses and positions the pressure gauge. In addition, the central axis of the annular guide groove 42 is collinear with the central axis of the output shaft of the drive motor 26, ensuring that the electric push rod 44 can smoothly rotate along the axis of the drive motor 26 when rotating around the drive motor 26. The cross section of the annular guide groove 42 is L-shaped. It should be noted that the provision of the positioning assembly 27 ensures that the assembly process of the pressure gauge on the valve body is stable and reliable, avoiding possible shaking or offset problems during the assembly process. After successfully completing the pressure gauge assembly task, the operator can easily separate the pressure reducer from the equipment. This step is not only simple to operate, but also does not require complex tools or professional skills, greatly facilitating the subsequent installation of another pressure gauge, making the entire assembly process smoother and more efficient, greatly improving the overall efficiency of the assembly work, and reducing the investment in time and labor costs. It should also be noted that the maximum tilting angle of the support plate 35 and the pressure plate 34 is 45°. When the support plate 35 and the pressure plate 34 are tilted to the maximum angle, the mounting rod 36 slides in the slide groove 39 to limit the angle of the support plate 35 and the pressure plate 34. The principle of positioning the pressure gauge using the positioning mechanism 27 is as follows: the transmission plate 45 is moved by the drive of the electric push rod 44, and the extrusion transmission effect between the guide groove 46 and the guide rod 40 is utilized, and the transmission force of the movable plate 38 is utilized to cause the support plate 35 and the pressure plate 34 to be flipped along the axis of the rotating rod 33 after being subjected to force, until the pressure gauge contacts the slot 61 and the rubber gasket 62, thereby completing the positioning of the pressure gauge.
