Description

Technical Field

[0001] The utility model belongs to the technical field of flange production, in particular to a flange surface spraying structure. Background Art

[0002] Flanges are parts that connect pipes to each other and are used to connect pipe ends. There are bolt holes on the flanges, and bolts connect the two flanges tightly. Flange connection is an important connection method for pipeline construction. In the marine, chemical, environmental protection, cement, petroleum, metallurgy and other industries, pipelines and equipment need to have strong corrosion resistance. Since flanges are inevitably exposed to the external environment, they need to be sprayed with a layer of protective paint to improve their anti-corrosion performance and avoid corrosion and oxidation.

[0003] In the existing production process, most of the processing methods for painting flanges are that workers use a spray gun to spray paint on the surface of the flange. This method of painting is prone to uneven painting, resulting in uneven paint thickness on various parts of the flange surface, which affects the spraying effect.

[0004] Therefore, the utility model provides a flange surface spraying structure. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a flange surface spraying structure, which solves the problem of uneven spraying when manually spraying paint on the flange.

[0006] To achieve the above-mentioned purpose, according to an embodiment of the first aspect of the utility model, a flange surface spraying structure is provided, comprising: a spray box, a clamping assembly for clamping the flange is installed on the bottom plate of the spray box, and a rotating assembly is also arranged inside the spray box;

[0007] The rotating assembly includes a motor, a fixed plate and a passive gear. The motor is fixedly mounted on the top plate of the spray box, and the output shaft of the motor is fixedly mounted with a driving shaft; a plurality of suspension rods are fixedly mounted on the fixed plate, and the suspension rods are fixedly connected to the top plate of the spray box; the driving shaft passes through the fixed plate at one end away from the motor and is fixedly mounted with a driving gear, and the fixed plate is rotatably connected with the driving shaft; two fixed shafts are fixedly mounted on the passive gear, and both fixed shafts are parallel to the fixed plate; and the passive gear is meshed with the active gear; the two ends of the fixed plate are also rotatably connected with rotating shafts, and the end of the rotating shaft away from the fixed plate is rotatably connected with the fixed shaft;

[0008] The passive gear is also provided with a spraying assembly for spraying paint on the flange.

[0009] Preferably, the clamping assembly is arranged inside the spraying box and includes a protection box, a rotating sleeve and a rotating rod. The protection box and the rotating sleeve are fixedly installed on the bottom plate of the spraying box, and a servo motor is fixedly installed inside the protection box; the rotating rod is rotatably connected with the rotating sleeve, one end of the rotating rod is fixedly connected with the output shaft of the servo motor, and the other end is fixedly connected with an electric push rod. A clamping plate is fixedly installed at the end of the electric push rod.

[0010] Preferably, the spraying assembly includes a storage tank and a spraying pump. The storage tank is fixedly installed on the side plate of the spraying box, the spraying pump is fixedly installed on the passive gear, the spraying pump is located between the passive gear and the clamping assembly, a spray head is fixedly installed on the spraying pump, a hose is installed between the storage tank and the spraying pump, and the hose communicates the storage tank and the spraying pump.

[0011] Preferably, the spray head is obliquely installed on the spraying pump, and the spray orifice of the spray head points to the flange.

[0012] Preferably, a bearing is arranged at the connection between the fixed plate and the drive shaft, and the drive shaft is rotatably connected with the fixed plate through the bearing.

[0013] Preferably, at least two groups of the clamping assemblies are provided; the height of the clamping plate is less than the thickness of the flange, and when the clamping plate clamps the outer wall of the flange, the upper and lower surfaces of the clamping plate do not exceed the upper and lower surfaces of the flange.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: when the motor is started, the output shaft drives the active gear to rotate. Through the meshing of the active gear and the passive gear and the constraint of the fixed shaft and the rotating shaft on the passive gear, the passive gear makes a circular motion along the outer ring of the active gear. The spraying pump and the spray head fixed on the passive gear rotate accordingly, and the flange is evenly sprayed. The design of rotary spraying enables the paint sprayed by the spray head to quickly cover the entire surface of the flange, avoiding the problems of uneven spraying or omission, improving the spraying efficiency. The inclination angle set between the spray head and the spraying pump ensures that the paint can cover all parts of the flange, including the inner wall and the edge area that are difficult to reach, achieving a comprehensive and uniform spraying effect;

[0015] Through the combined use of the electric push rod and the servo motor, the flange can be stably and efficiently clamped. The electric push rod provides flexible clamping force adjustment to ensure that the flange will not slide or move during the spraying process. At the same time, the high-precision control of the servo motor makes the flipping action of the flange more accurate and fast, significantly improving the spraying efficiency.

[0016] The entire spraying process has a high degree of automation, reducing the complexity and labor intensity of manual operation. Parameters such as the clamping force and the spraying speed can be flexibly adjusted through the control system to meet the spraying requirements of different specifications of flanges.

[0021] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1-3 shown, a spraying structure on the surface of a flange includes: a spraying box 1, and at least two groups of clamping assemblies for clamping the flange are installed on the bottom plate of the spraying box 1;

[0023] The clamping assembly is arranged inside the spraying box 1 and includes a protection box 11, a rotating sleeve 14 and a rotating rod 13. The protection box 11 and the rotating sleeve 14 are fixedly installed on the bottom plate of the spraying box 1, and a servo motor 12 is fixedly installed inside the protection box 11; the rotating rod 13 is rotatably connected to the rotating sleeve 14, one end of the rotating rod 13 is fixedly connected to the output shaft of the servo motor 12, and the other end is fixedly connected to an electric push rod 15, and a clamping plate 16 is fixedly installed at the end of the electric push rod 15;

[0024] The height of the clamping plate 16 is less than the thickness of the flange. When the clamping plate 16 clamps the outer wall of the flange, the upper and lower surfaces of the clamping plate 16 do not exceed the upper and lower surfaces of the flange;

[0025] After one side of the flange is sprayed, start the servo motor 12, drive the rotating rod 13 and the electric push rod 15 installed on the rotating rod 13 to rotate through the servo motor 12, so as to realize the flipping of the upper and lower surfaces of the flange, and thus spray paint on the other side of the flange;

[0026] Through the combined use of the electric push rod 15 and the servo motor 12, the flange can be stably and efficiently clamped; the electric push rod 15 provides flexible clamping force adjustment to ensure that the flange does not slide or move during the spraying process. At the same time, the high-precision control of the servo motor 12 makes the flipping action of the flange more accurate and rapid, significantly improving the spraying efficiency; the upper and lower surfaces of the clamping plate 16 do not exceed the upper and lower surfaces of the flange, and this design effectively avoids the clamping plate 16 blocking the paint during the spraying process, ensuring that the paint can evenly cover the entire surface of the flange; the protection box 11 isolates the servo motor 12 from the spraying environment, preventing damage to the servo motor 12 caused by paint splashing during the spraying process;

[0027] A rotating assembly 2 is further provided inside the spraying box 1; the rotating assembly 2 includes a motor 21, a fixing plate 23 and a passive gear 26. The motor 21 is fixedly installed on the top plate of the spraying box 1, and a driving shaft 22 is fixedly installed on the output shaft of the motor 21;

[0028] A number of suspension rods 24 are fixedly installed on the fixing plate 23, and the suspension rods 24 are fixedly connected to the top plate of the spraying box 1; the end of the driving shaft 22 away from the motor 21 passes through the fixing plate 23 and a driving gear 25 is fixedly installed. A bearing is provided at the connection between the fixing plate 23 and the driving shaft 22, and the driving shaft 22 is rotationally connected to the fixing plate 23 through the bearing;

[0029] Two fixing shafts 28 are fixedly installed on the passive gear 26, and both of the two fixing shafts 28 are parallel to the fixing plate 23; and the passive gear 26 meshes with the driving gear 25; two rotating shafts 27 are respectively rotationally connected to both ends of the fixing plate 23, and the end of the rotating shaft 27 away from the fixing plate 23 is rotationally connected to the end of the fixing shaft 28 away from the passive gear 26;

[0030] When the motor 21 is started, the output shaft drives the driving gear 25 to rotate. Since the driving gear 25 meshes with the passive gear 26, the fixing shafts 28 fixedly installed on the passive gear 26 drive the rotating shaft 27 to make a circular motion around the connection point of the rotating shaft 27 and the fixing plate 23; at the same time, due to the constraint of the rotating shaft 27 and the fixing shaft 28 on the passive gear 26, at this time the passive gear 26 makes a circular motion along the outer circle of the driving gear 25;

[0031] A spraying assembly 3 for spraying paint on the flange is further installed on the passive gear 26; the spraying assembly 3 includes a storage tank 31 and a spraying pump 33. The storage tank 31 is fixedly installed on the side plate of the spraying box 1, and the spraying pump 33 is fixedly installed on the passive gear 26. The spraying pump 33 is located between the passive gear 26 and the clamping assembly;

[0032] A spray head 34 is fixedly installed on the spray pump 33. The spray head 34 is set at a certain inclination angle with the spray pump 33, and the jet orifice of the spray head 34 points to the fixed flange. This ensures that during the rotary spraying process, the spray head 34 can cover all parts of the flange, including the inner wall and the hard-to-reach edge areas, thus achieving a comprehensive and uniform spraying effect.

[0033] A hose 32 is installed between the storage tank 31 and the spray pump 33. The hose 32 connects the storage tank 31 and the spray pump 33.

[0034] Since the spraying assembly 3 can rotate with the circumferential movement of the passive gear 26, the spray head 34 can continuously spray different positions of the flange. There is no need to frequently move the spray head 34 or adjust the position of the flange. The design of rotary spraying enables the spray head 34 to quickly cover the entire surface of the flange, avoiding the problems of uneven spraying or omission. This greatly reduces the spraying time and improves the production efficiency.

[0035] The working principle of the present utility model: Control the electric push rod 15 to extend to clamp and fix the two side walls of the flange. When the motor 21 is started, the output shaft drives the active gear 25 to rotate. Due to the constraints of the fixed shaft 28 and the rotating shaft 27, the passive gear 26 makes a circumferential movement along the outer ring of the active gear 25. The spray pump 33 and the spray head 34 fixed on the passive gear 26 rotate to spray the flange. When one side is sprayed, the servo motor 12 is started to drive the rotating rod 13 and the electric push rod 15 to rotate, thereby realizing the up-and-down flipping of the flange for spraying the other side.

[0036] The above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model.
