Description

Technical Field

[0001] This utility model relates to the field of tooling technology for spray-coated ball valves, and more particularly to a tooling for plasma spray-coated ball valves. Background Technology

[0002] In the actual operation of plasma spraying processes, a tooling system for plasma spraying ball valves plays a crucial role. It is specifically designed for ball valves and is a precise and practical specialized device.

[0003] Currently, tooling for ball valves is typically fixed-angle. Fixed-angle tooling precisely holds the ball valve in a preset position and angle, ensuring that the distance and angle between the spray gun and the ball valve surface remain consistent each time it is sprayed. This improves the repeatability and consistency of the spraying process, guaranteeing uniform coating thickness and stable quality. By setting a specific fixed angle, it is easy to shield and protect areas of the ball valve that do not require spraying, preventing coating contamination of non-spraying areas and reducing subsequent processing steps.

[0004] While fixed-angle tooling offers precise positioning, once the angle is determined, it is only suitable for ball valves requiring a specific angle. Different tooling is needed for ball valves with different angle requirements, increasing tooling costs and management complexity. Designing and manufacturing specialized fixed-angle tooling based on the ball valve's specific shape, size, and coating requirements is complex and time-consuming, increasing production costs and project timelines. Therefore, this paper proposes a tooling solution for plasma-coated ball valves to address these issues. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tooling for a plasma spraying ball valve includes a base and two connecting plates. Two distance adjustment components are provided on the inner sides of both ends of the base, and mounting and fixing components are provided on both sides of the base. Rotation components are provided on the inner sides of both connecting plates, and positioning and snapping components are provided on the inner sides of the ends of both connecting plates.

[0008] The rotating assembly includes a second gear, which is rotatably connected to the inner side of the connecting plate. A first gear is rotatably connected to the inner side of the connecting plate. The first gear and the second gear are meshed with each other. A connecting ring is fixedly connected to the inner side of the second gear.

[0009] As a further description of the above technical solution:

[0010] The positioning and snapping assembly includes a housing, which is fixedly connected to the inner side of the connecting ring.

A worm is rotatably connected to the inner side of the housing, and the worm is meshed with the side of the worm gear. The end of the worm is connected to an external device.

[0011] As a further description of the above technical solution:

[0012] The positioning and snapping assembly also includes a plurality of positioning sliders, all of which are slidably connected to the outer side of the housing and the spiral plate;

[0013] As a further description of the above technical solution:

[0014] The distance adjustment assembly includes a slider, which is fixedly connected to the bottom of the connecting plate and slidably connected to the inner side of the base. An electric push rod is fixedly connected to the inner side of the end of the base, and the other end of the electric push rod is fixedly connected to the side of the slider.

[0015] As a further description of the above technical solution:

[0016] The mounting and fixing assembly includes a slot block, which is fixedly connected to the outside of the base. A snap-fit ​​block is slidably connected to the inside of the slot block, and a fixing bolt is fixedly connected to the end of the snap-fit ​​block.

[0017] As a further description of the above technical solution:

[0018] Both gears are fixedly connected to the inner side of each gear, a drive motor is fixedly connected to the outer side of one of the connecting plates, a protective shell is fixedly connected to the outer side of the drive motor, the protective shell is fixedly connected to the outer side of the connecting plate, and the drive motor is fixedly connected to the inner side of one of the gears.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, a drive motor drives gear one, which in turn rotates gear two, causing the connecting ring and the ball valve body on the connecting ring to rotate. This allows the spray gun to uniformly spray all surfaces of the ball valve, avoiding spray dead zones, significantly improving the integrity and uniformity of the coating, and enhancing the overall performance of the ball valve, such as strengthening its wear resistance and corrosion resistance.

[0025] 2. In this invention, a worm gear drive rotates a spiral plate, causing a positioning slider to move radially and clamp the ball valve. This structure provides a strong and stable clamping force, ensuring that the ball valve will not shift or shake during the spraying process, thus guaranteeing the stability of the spraying process and improving coating quality. Multiple positioning sliders can accommodate ball valves of different outer diameters, and the rubber anti-slip slider increases friction, further improving the tooling's adaptability to ball valves of different specifications.

[0033] 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.

[0034] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a tooling for a plasma spraying ball valve, comprising a base 1 and two connecting plates 6. Two distance adjustment components are provided on the inner sides of both ends of the base 1, and mounting and fixing components are provided on both sides of the base 1. Rotating components are provided on the inner sides of both connecting plates 6, and positioning and snapping components are provided on the inner sides of the ends of both connecting plates 6.

[0035] The rotating assembly includes gear 2 (9), which is rotatably connected to the inner side of connecting plate 6. Gear 1 (8) is rotatably connected to the inner side of connecting plate 6. Gear 1 (8) and gear 2 (9) are meshed together. A connecting ring 12 is fixedly connected to the inner side of gear 2 (9). Telescopic rods 7 are fixedly connected to the inner sides of both gears 1 (8). A drive motor 13 is fixedly connected to the outer side of one of the connecting plates 6. A protective shell 5 is fixedly connected to the outer side of the drive motor 13. The protective shell 5 is fixedly connected to the outer side of the connecting plate 6. The drive motor 13 is fixedly connected to the inner side of one of the gears 1 (8). When the drive motor 13 starts, it drives gear 1 (8) to rotate. Since gear 1 (8) and gear 2 (9) are meshed, the rotation of gear 1 (8) drives gear 2 (9) to rotate. The connecting ring 12 is fixedly connected to the inner side of gear 2 (9), so the rotation of gear 2 (9) drives the connecting ring 12 to rotate, thereby causing the ball valve body 4, which is mounted on the positioning and locking assembly inside the connecting ring 12, to rotate, facilitating all-around spraying of the ball valve by the spray gun. The telescopic rods 7 can adapt to changes in the distance between the two gears 1 (8) to a certain extent.

[0036] Reference Figure 1 , Figure 2 and Figure 4The positioning and locking assembly includes a housing 11, which is fixedly connected to the inner side of a connecting ring 12. A worm gear 17 is rotatably connected to the inner side of the housing 11, and a spiral plate 16 is fixedly connected to the side of the worm gear 17. A worm 18 is rotatably connected to the inner side of the housing 11, and the worm 18 is meshed with the side of the worm gear 17. The end of the worm 18 is connected to an external device. When the external device drives the worm 18 to rotate, the rotation of the worm 18 will drive the worm gear 17 to rotate because the worm 18 is meshed with the worm gear 17. Since the spiral plate 16 is fixedly connected to the side of the worm gear 17, the rotation of the worm gear 17 will cause the spiral plate 16 to rotate accordingly. The positioning and locking assembly also includes multiple positioning sliders 15, which are slidably connected to the outer sides of the housing 11 and the spiral plate 16. The rotation of the spiral plate 16 will cause the positioning sliders 15 to slide linearly in the radial direction within the housing 11. As the multiple positioning sliders 15 move towards the center, the rubber anti-slip blocks 19 on their sides contact and lock against the outer side of the ball valve body 4, thus achieving positioning and locking of the ball valve. Each of the multiple positioning sliders 15 has a rubber anti-slip block 19 fixedly connected to its side. The ball valve body 4 is located on the outer side of the multiple rubber anti-slip blocks 19. The rubber anti-slip blocks 19 increase friction and prevent the ball valve 4 from sliding during rotation.

[0037] Reference Figure 1 and Figure 3 The distance adjustment assembly includes a slider 10, which is fixedly connected to the bottom of the connecting plate 6 and slidably connected to the inner side of the base 1. An electric push rod 14 is fixedly connected to the inner side of one end of the base 1, and the other end of the electric push rod 14 is fixedly connected to the side of the slider 10. When the electric push rod 14 is activated, it will extend and retract, pushing the slider 10 to slide inside the base 1. The sliding of the slider 10 causes the connected connecting plate 6 to move, thereby adjusting the distance between the two connecting plates 6 to accommodate the size of ball valves of different specifications.

[0038] Reference Figure 1 and Figure 5 The mounting and fixing assembly includes a slot block 3, which is fixedly connected to the outside of the base 1. A snap-fit ​​block 2 is slidably connected to the inside of the slot block 3, and a fixing bolt 20 is fixedly connected to the end of the snap-fit ​​block 2. When the tooling needs to be installed, the snap-fit ​​block 2 is inserted into the slot block 3, and then the snap-fit ​​block 2 is fixed to the external equipment or work platform by the fixing bolt 20, thereby completing the installation and fixing of the tooling.

[0039] Working principle: First, start the electric push rod 14, which will push the slider 10 to slide inside the base 1, thereby driving the connecting plate 6 to move, realizing the adjustment of the distance between the two connecting plates 6 to adapt to ball valve bodies 4 of different sizes.

[0040] Then, the external device drives the worm gear 18 to rotate, and the worm wheel 17 meshing with the worm gear 18 will rotate accordingly. The spiral plate 16 fixed to the side of the worm wheel 17 will also rotate. Since the positioning slider 15 is slidably connected to the outer side of the housing 11 and the spiral plate 16, the rotation of the spiral plate 16 will cause the positioning slider 15 to slide radially inside the housing 11. The movement of multiple positioning sliders 15 toward the center can lock the ball valve body 4, achieving positioning and locking.

[0041] Finally, when the drive motor 13 is started, it will drive gear 8 to rotate. Since gear 8 and gear 9 mesh with each other, gear 9 will also rotate, thereby driving the connecting ring 12 fixed inside gear 9 to rotate, so as to realize the rotation of the ball valve body 4 connected to the connecting ring 12 for all-round spraying.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
