Description

Technical Field

[0001] This utility model relates to the field of valve stem technology for ring gate valves, and in particular to a processing device for stainless steel gate valve transmission stems. Background Technology

[0002] The actuation stem of a stainless steel gate valve is also known as the valve stem. Some gate valves have connection holes at both ends of the valve stem. Specifically, the connection hole at the upper end of the valve stem (near the operating end) is used to fix a handwheel, handle, or electric / pneumatic actuator. Bolts or pins are inserted into the connection hole to ensure effective torque transmission and achieve valve opening and closing. Standardized interface: The design of the connection hole conforms to international standards (such as ISO and API), facilitating compatibility with common drive devices and improving interchangeability.

[0003] Lower end connected to gate: The lower end of the valve stem is usually mechanically fixed to the gate (valve disc) through a connecting hole, such as using a T-head, threaded pin, or bolt. This design ensures that the linear movement of the valve stem is directly converted into the raising and lowering of the gate, achieving sealing or flow.

[0004] When polishing a valve stem, it is necessary to position the valve stem to ensure its stability during polishing. The valve stem polishing device disclosed in the prior art (CN222430366U) can clamp the valve stem, but the clamped parts cannot be polished after both ends are clamped, so it is necessary to disassemble and perform subsequent polishing, which reduces the efficiency of valve stem processing.

[0005] Existing valve stem polishing devices rarely use fixtures adapted to the inherent shape of the valve stem for positioning; instead, they often use three-jaw chucks, which prevent the clamped portion from being polished. Therefore, this application proposes a stainless steel gate valve transmission stem processing device. Utility Model Content

Detailed Implementation

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1-4 As shown in the figure, this utility model embodiment proposes a stainless steel gate valve transmission rod processing device, comprising:

[0025] A frame 1 is provided, on which a motor 3 is mounted. A motor frame is also mounted on the frame 1, and the motor 3 is mounted on the motor frame, which provides stable support for the motor 3. A first connecting rod 4 is fixed to the output end of the motor 3, which abuts against the transmission rod. The first connecting rod 4 can be detachably mounted on the output end of the motor 3. For example, a flange is welded to the output end of the motor 3, and a flange is also welded to the first connecting rod 4. In this way, disassembly and assembly can be achieved through the flange connection, so as to limit the movement of different types of transmission rods.

[0026] The first connecting rod 4 matches the connecting hole at the end of the transmission rod, that is, the first connecting rod 4 can be slidably connected in the connecting hole. The first connecting rod 4 has an outer ring or protrusion smaller than the outer diameter of the transmission rod, which is used to support the transmission rod so as to clamp the transmission rod in the future.

[0027] The frame 1 is equipped with a movable block 7, and a first electric push rod 6 is mounted on the frame 1. The output end of the first electric push rod 6 is fixedly connected to the movable block 7. A frame body is mounted on the frame 1, and the first electric push rod 6 is mounted on the frame body. Thus, the first electric push rod 6 drives the movable block 7 and the second connecting rod 8 to move, so that the second connecting rod 8 extends into the connecting hole at the end of the transmission rod. Similarly, an outer ring or protrusion smaller than the outer diameter of the transmission rod is fixed on the second connecting rod 8 to support the transmission rod. The first electric push rod 6 drives the second connecting rod 8 to move until the outer ring or protrusion abuts against the transmission rod, thus achieving the clamping of the transmission rod.

[0028] The operation of motor 3 can drive the first connecting rod 4, the second connecting rod 8 (the first connecting rod 4 and the second connecting rod 8 are coaxially arranged) and the transmission rod to rotate, so as to facilitate subsequent polishing. Since the position of the second connecting rod 8 can be adjusted, it can be used for polishing of transmission rods of various lengths.

[0029] A second connecting rod 8, which abuts against the transmission rod, is rotatably mounted on the movable block 7. A bearing is installed on the movable block 7, and a short shaft is interference-fitted inside the bearing. The short shaft is also connected to the second connecting rod 8 via a flange, so that the transmission rod can be replaced according to its model in the future, so as to achieve polishing of different models of transmission rods.

[0030] To ensure the stable movement of the movable block 7, a guide rail is provided on the frame 1, and the movable block 7 slides on the guide rail. A connecting block 12 is slidably connected to the guide rail, and the connecting block 12 is connected to the movable block 7 through a connecting plate 11. A through groove 9 is provided on the frame 1, and the through groove 9 is positioned opposite to the connecting plate 11.

[0031] The first connecting rod 4 and the second connecting rod 8 are adapted to and clamp the two ends of the transmission rod, and the motor 3 can drive the first connecting rod 4, the second connecting rod 8 and the transmission rod to rotate, as described above.

[0032] When the transmission rod has a certain length, centrifugal force will cause instability in the middle position when the transmission rod is driven to rotate, so it needs to be supported; a support assembly is specifically provided; the support assembly can change the length and position of the transmission rod, and the support assembly is used to support the transmission rod; the support assembly includes a second electric push rod 20 located in the through groove 9 and fixed to the bottom of the connecting plate 11. The output end of the second electric push rod 20 is fixed with a lifting block 13, and the bottom of the lifting block 13 is fixed with a guide rod. The guide rod passes through the connecting plate 11 and is slidably connected to it, so as to guide the lifting block 13 and ensure its stable movement.

[0033] The upper end of the lifting block 13 is equipped with a trench-shaped mounting frame 14, and two transmission rollers 15 supporting the transmission rod are rotatably mounted on the mounting frame 14. When the transmission rod is clamped and positioned by the first connecting rod 4 and the second connecting rod 8, the second electric push rod 20 drives the lifting block 13, the mounting frame 14 and the transmission rollers 15 to move upward, so that the transmission rollers 15 abut against the transmission rod, thus supporting the transmission rod and ensuring its stable support.

[0034] like Figure 1As shown, since the transmission roller 15 is located between the first connecting rod 4 and the second connecting rod 8, it can support the transmission rod and ensure its stable rotation. The connecting plate 11 moves with the movable block 7, so the position of the transmission roller 15 can be adjusted so that it can support the transmission rod close to the middle when clamping and supporting it, ensuring the stable rotation of the transmission rod. The transmission roller 15 supports the bottom of the transmission rod, and the upper end is pressed against the transmission rod by the polishing block 21, which can ensure the stable rotation of the transmission rod.

[0035] The processing assembly includes a drive unit 22 mounted on the frame 1. The drive unit 22 is an industrial-grade electric slide rail and an electric slider. The electric slider slides on the electric slide rail. The moving frame 16 is mounted on the electric slider. The movement of the electric slider drives the moving frame 16 to move.

[0036] A movable frame 16 is mounted on the drive unit 22. A lifting mounting block 10 is mounted on the movable frame 16. A third electric push rod 19 is mounted on the movable frame 16. The output end of the third electric push rod 19 is fixedly connected to the upper end of the mounting block 10. A guide rod is fixed to the upper end of the mounting block 10. The guide rod passes through the movable frame 16 and is slidably connected to it. In this way, when the third electric push rod 19 drives the mounting block 10 to move, it can ensure its stable up and down movement.

[0037] A polishing block 21 is installed at the bottom of the mounting block 10. The polishing block 21 is connected to the mounting block 10 by bolts for subsequent disassembly and replacement. When the transmission rod rotates, the third electric push rod 19 drives the mounting block 10 and the polishing block 21 to move down, so that the polishing block 21 abuts against the transmission rod. The movement of the moving frame 16 can drive the polishing block 21 to move, thus polishing the rotating transmission rod.

[0038] Since the first connecting rod 4 and the second connecting rod 8 are inserted into both ends of the transmission rod, they do not obstruct the outer walls of both ends of the transmission rod. Therefore, the transmission rod can be fully polished without the need for subsequent processing.

[0039] Dust is inevitably generated during the polishing process. An arc-shaped clamp 2 is installed on one side of the mounting block 10, and a dust suction pipe 5 is held in the arc-shaped clamp 2. A placement frame 18 is installed on the moving frame 16, and a vacuum cleaner 17 is placed in the placement frame 18. The air inlet of the vacuum cleaner 17 is connected to the dust suction pipe 5. During polishing, the vacuum cleaner 17 works at the dust suction pipe 5 to generate negative pressure, thereby removing the dust generated during polishing and reducing the impact on the working environment.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
