Description

Technical Field

[0001] The utility model relates to the technical field of valve processing, in particular to a spraying device for valve processing. Background Art

[0002] Valves are control components in fluid delivery systems, performing functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion, or overflow and pressure relief. Valves used in fluid control systems come in a wide variety of types and specifications, from the simplest shutoff valve to the most complex valves used in automatic control systems. Because valves often operate in humid and complex environments, manufacturers typically spray-coat them to improve their corrosion resistance and extend their service life.

[0003] Traditional spraying equipment usually places the valve directly on the upper surface of a designated platform plate, and then sprays the valve surface directly through a sprayer. Since it is difficult to clamp and rotate the valve during spraying, it is difficult to effectively spray the paint on the lower surface of the valve when it is placed. Manual flipping and secondary spraying are required, which not only increases the labor intensity of the staff, but also reduces the spraying of the valve. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-6 In this embodiment, a spraying device for valve processing includes a base 1, a stand 2 is fixed on the top of the base 1, an adjusting component 4 is installed on the upper part of the front of the stand 2, and a clamping and rotating component 5 is installed in the middle part, five spray guns 6 are installed on the movable end of the adjusting component 4, and a support component 3 is installed between the base 1 and the stand 2 and located below the spray gun 6.

[0022] In the above structure, the valve can be lifted to a certain height by the support assembly, which makes it convenient to clamp and fix the valve by the clamping and rotating assembly, and then the spray gun is driven close to the valve for spraying by the adjusting assembly. During the spraying process, the clamping and rotating assembly drives the valve to rotate, so that the paint is evenly sprayed on the valve. Therefore, the efficiency of valve processing is improved through automated spraying.

[0023] like Figure 2In the direction shown, in order to lift the valve to a certain height, the platform support assembly 3 includes a lifting platform 306 slidably connected to the front of the stand 2, a limiting groove is provided on the platform of the lifting platform 306, and a bearing seat 302 fixed on the base 1, and limit blocks 301 distributed at the four corners of the bearing seat 302. The tops of the two limit blocks 301 on the left are V-shaped, and the tops of the two limit blocks 301 on the right are inclined toward the lower left. A rotating block 303 is fixed between the two axial ends of the bearing seat 302, and both sides of the rotating block 303 are isosceles triangles. Guide wheels 304 that are attached to the bottom of the lifting platform 306 are rotatably installed on both sides of the rotating block 303. A propulsion cylinder 305 hinged to the rotating block 303 is hinged on the base 1. The limit groove on the lifting platform can limit the valve, and the thrust cylinder can be used to drive the rotating block to rotate. During the rotation, the limit block will limit the rotation limit position, so that the guide wheel can slide under the lifting platform to lift the lifting platform, so that the valve can be lifted to a certain height suitable for clamping.

[0024] like Figure 3-5 In the direction shown, the valve is clamped and rotated. The clamping and rotating assembly 5 includes a lifting plate 504 installed on the front of the stand 2. A side push plate 505 and a push clamping plate 507 slidably connected to the side push plate 505 are installed on the plate surface of the lifting plate 504. The push clamping plate 507 and the side push plate 505 are both L-shaped. A push clamping cylinder 506 connected to the push clamping plate 507 is installed on the left side of the side push plate 505. An auxiliary rotating shaft 512 is installed on the side push plate 505. A drive shaft 513 is installed on the side of the push clamping plate 507 opposite to the auxiliary rotating shaft 512. A rotating plate 514 is fixed to the opposite end of the push clamping plate 507 and the auxiliary rotating shaft 512, and relative protrusions 515 are fixed to the opposite sides of the two rotating plates 514. When the support assembly lifts the valve to a certain height, the valve is located between the two rotating plates. At this time, the push-clamp cylinder drives the push-clamp plate to move until the protrusion on the push-clamp plate extends to one side of the valve. Then the valve is pushed to put the other protrusion into the other side of the valve. The product is clamped and fixed by the two rotating plates. During the spraying process, the drive shaft rotates and cooperates with the auxiliary rotating shaft to drive the product to complete the rotation.

[0025] The lower part of the stand 2 is provided with an upper cylinder 501, the ejection end of the upper cylinder 501 is fixed with a top plate 502, the lifting plate 504 is fixed on the top plate 502, and the front of the top plate 502 is provided with a side push cylinder 503, the ejection end of the side push cylinder 503 is fixedly connected to the side push plate 505, and the side push plate 505 is slidably connected to the lifting plate 504. The upper cylinder can drive the clamping rotating assembly to move to a suitable position, and then, under the push of the side push cylinder, the side push plate is driven to move left and right, so that the protrusion on the side push plate first extends to the valve port, and then the above-mentioned clamping cylinder is operated to drive the clamping plate to move, so that another protrusion extends into the valve to complete the clamping. When the clamping is completed, the side push cylinder can be used to drive the product to move left and right again, so that the valve can be driven to complete the movement in the X and Y axis directions according to the actual processing conditions.

[0026] At the same time, the side push plate 505 is rotatably connected to a sleeve 508 located below the push and clamp cylinder 506. The front and back sides of the sleeve 508 are both provided with waist holes 509. The side of the push splint 507 opposite to the sleeve 508 is rotatably connected to an inner rod 510 extending into the interior of the sleeve 508. The outer side of the inner rod 510 is mounted with a bearing 511 sliding in the waist hole 509. The sleeve and the inner rod can improve the support of the push splint and the side push plate. At the same time, the bearing and the waist hole can move together with the push splint. The bearing can improve the smoothness of movement, and the waist hole can also play a role in limiting.

[0027] In addition, the bottom of the protruding end of the protruding block 515 is forked. The two protruding blocks 515 have bullet-shaped sides facing each other, and the opposite sides are square. The protruding ends of the protruding blocks 515 pass through the rotating plate 514, and are hingedly connected to an upper push plate 517 located in the fork. Furthermore, a push-up cylinder 516 is mounted on the bottom of the protruding block 515 on the back side of the rotating plate 514, which is hingedly connected to one end of the push-up plate 517. When the protruding block extends into the valve opening, the push-up cylinder is activated, pushing one end of the push-up plate upward, causing the other end to move downward to contact the valve opening. This improves the stability and firmness of the clamping and prevents displacement during rotation.

[0028] like Figure 6 In the direction shown, the adjustment assembly 4 includes a downward push cylinder 401 installed on the top of the stand 2, and a downward push plate 402 connected to the top of the front side in a sliding connection with the ejection end of the downward push cylinder 401. Two forward push cylinders 403 are installed at the bottom of the downward push plate 402, and a forward push plate 404 fixed to the ejection end of the forward push cylinder 403 is slidably connected. The spray gun 6 is installed on the forward push plate 404. The downward push cylinder drives the downward push plate to move up and down, while the forward push cylinder drives the forward push plate to move forward and backward. Therefore, it is possible to drive the spray gun to move in the Y and Z directions, so that the spraying position can be adjusted according to the actual situation during the spraying process.

[0029] The working principle of the above embodiment is:

[0030] The upper push cylinder drives the upper push plate to tilt up, and the upper push plate contacts and squeezes the inner wall of the valve, thereby improving the firmness of the clamping. Then the lower push cylinder drives the lower push plate to move downward until the spray gun reaches the appropriate position to spray the valve. During the spraying process, the drive shaft rotates and cooperates with the auxiliary rotating shaft to drive the valve to rotate, so that the paint can be evenly sprayed on the outside of the valve, thereby improving the efficiency of automatic spraying and flipping.

[0031] When the size needs to be adjusted during the spraying process, the side push cylinder can push the side push plate to move and adjust the position of the valve. At the same time, the front push cylinder drives the front push plate to move, which can adjust the position of the spray gun. The valve or spray gun can be adjusted according to production needs.
