[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-5This utility model provides a valve surface painting device, including a housing 2 and a door panel 3 rotatably connected to one side of the housing 2 via a hinge. A first housing 1 is bolted to the top of the housing 2 and located in the middle position. A slide rod 11 is slidably connected to the inner wall of the top of the housing 2, and one end of the slide rod 11 passes through the housing 2. Two symmetrically arranged connecting rods 10 are bolted to the outer circumferential wall of the slide rod 11 at the top of the housing 2. A ball bearing 9 is rotatably connected to one end of the connecting rod 10. A wave groove 7 is formed on the inner circumferential wall of the first housing 1 to cooperate with the sliding of the two ball bearings 9. A drive assembly for driving the slide rod 11 to rotate is provided on the inner wall of the top of the first housing 1. The drive assembly includes a connecting shaft 8 rotatably connected to the inner wall of the top of the first housing 1 and located in the middle position via a bearing. A groove 14 is formed in the slide rod 11, and an elliptical block 15 is slidably connected in the groove 14. One end of the connecting shaft 8 passes through the door panel 15. The slide bar 11 is fixedly connected to the elliptical block 15. A servo motor that drives the connecting shaft 8 to rotate along the axis is fixed to the top of the first housing 1 by bolts. When the servo motor is started, it drives the connecting shaft 8 to rotate. The connecting shaft 8 drives the slide bar 11 to rotate through the elliptical block 15. At the same time, the elliptical block 15 slides in the groove 14. When the drive assembly is started, the drive assembly drives the slide bar 11 to rotate. The slide bar 11 drives the two connecting rods 10 to rotate. The two connecting rods 10 drive the two balls 9 to slide in the wave groove 7. Due to the shape of the wave groove 7, the two balls 9 make reciprocating motion in the wave groove 7. The two balls 9 drive the two connecting rods 10 to make up-down reciprocating motion. The two connecting rods 10 drive the slide bar 11 to make up-down reciprocating motion. The slide bar 11 drives the valve on the clamping assembly to make up-down reciprocating motion and rotate, thereby uniformly spraying paint on the valve and improving the uniformity of the paint spraying.

[0024] In this embodiment, both inner walls of the outer casing 2 are provided with a paint spraying assembly for spraying paint onto the valve. The paint spraying assembly includes a feed pipe 4 that is fixed to one inner wall of the outer casing 2 by bolts and has one end passing through the outer casing 2. Two symmetrically arranged nozzles 5 are welded to one end of the feed pipe 4 located inside the outer casing 2. The paint outlet pipe of the external paint spraying system is connected to the feed pipe 4. The paint enters from the feed pipe 4 and is then diverted to the two nozzles 5 for spraying, thereby ensuring that the paint can be sprayed evenly onto the valve.

[0025] The external painting system consists of paint buckets, pumps, pipes, etc. Those skilled in the art can set it up according to actual needs, which will not be described in detail here.

[0026] In this embodiment, the bottom of the slide rod 11 is provided with a clamping assembly for fixing the valve. The clamping assembly includes a connecting frame 13 fixed to the bottom of the slide rod 11 by bolts. The bottom of the connecting frame 13 is fixed with a second housing 12 by bolts. The bottom inner wall of the second housing 12 has a plurality of grooves 19 that penetrate the second housing 12 and are evenly distributed. A clamping block 20 is slidably connected in the grooves 19. A fixing block 17 is fixed to one side of the clamping block 20 by bolts. An electric push rod 16 is fixed to the top of the second housing 12 and located in the middle by bolts. The electric push rod 16 is located in the connecting frame 13. The piston end of the electric push rod 16 passes through the second housing 12, and a plurality of wedge blocks 18 are fixed to the outer circumference of the piston end by bolts. The top of the wedge block 18 has an inclined surface for pushing the fixing block 17 to move. The bottom outer side of the clamping block 20 is fixed with screws. The friction block is detachably installed. The outer side of the friction block is an arc-shaped surface that matches the inner wall of the valve inlet. The arc-shaped surface is provided with multiple evenly distributed anti-slip patterns. The anti-slip patterns on the arc-shaped surface of the friction block increase the friction between the friction block of the clamping block 20 and the valve, so that the clamping block 20 can hold the valve more stably through the friction block, preventing the valve from shaking or falling off during the painting process. Since the friction block is detachable, different friction blocks can be adapted to different valve inlet inner diameters. When the electric push rod 16 is activated, its piston end drives multiple wedge blocks 18 to move downwards simultaneously. The inclined surface of the wedge block 18 contacts the fixed block 17, pushing the multiple fixed blocks 17 to move outwards. The fixed block 17 drives the clamping block 20 to move outwards along the direction of the slide groove 19, thereby clamping the valve inlet.

[0027] It should be noted that the friction block in this application is made of high-temperature friction modifier and corrosion-resistant material to ensure a stable coefficient of friction and high-temperature resistance. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0028] In this embodiment, a spring 22 is fixed to one side of the clamping block 20 by bolts, and the other end of the spring 22 is fixed to the second housing 12. The spring 22 can assist the clamping block 20 to quickly return to the initial position and prepare for the next clamping.

[0029] In this embodiment, a guide rod 21 is fixed between the inner walls of both sides of the slide groove 19 by bolts, and the guide rod 21 is slidably connected to the clamping block 20. The guide rod 21 plays the role of guiding and supporting the sliding of the clamping block 20, ensuring that the clamping block 20 can slide smoothly along the predetermined trajectory, and avoiding the clamping block 20 from deviating or shaking during the sliding process.

[0030] In this embodiment, a collection box 6 for collecting paint is placed on the bottom inner wall of the outer casing 2. The collection box 6 collects the dripping paint, ensuring a clean working environment.

[0031] It should be noted that the servo motor and electric push rod 16 used in this application are existing technologies, and those skilled in the art can set them according to actual needs, which will not be elaborated here.

[0032] The use of this utility model involves the following steps:

[0033] S1: Open the door panel 3, insert the valve inlet into the outside of multiple clamping blocks 20, and then start the electric push rod 16. Its piston end drives multiple wedge blocks 18 to move downwards simultaneously. The inclined surface of the wedge block 18 contacts the fixed block 17, pushing multiple fixed blocks 17 to move outwards. The fixed block 17 drives the clamping blocks 20 to move outwards along the direction of the slide groove 19. Multiple clamping blocks 20 contact the inner wall of the valve inlet through the friction block and form a squeezing state, thereby clamping the valve inlet.

[0034] S2: Then close door panel 3;

[0035] S3: Then the paint outlet pipe of the external painting system is connected to the feed pipe 4. The paint enters from the feed pipe 4 and is then split into two nozzles 5 to spray out onto the valve.

[0036] S4: Simultaneously start the servo motor, which drives the connecting shaft 8 to rotate. The connecting shaft 8 drives the slide rod 11 to rotate through the elliptical block 15. At the same time, the elliptical block 15 slides in the groove 14. The slide rod 11 drives the two connecting rods 10 to rotate. The two connecting rods 10 drive the two balls 9 to slide in the wave groove 7. Due to the shape of the wave groove 7, the two balls 9 reciprocate in the wave groove 7. The two balls 9 drive the two connecting rods 10 to reciprocate up and down. The two connecting rods 10 drive the slide rod 11 to reciprocate up and down. The slide rod 11 drives the valve on the clamping assembly to reciprocate up and down and rotate.

[0037] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.
