Fixed corner brackets are installed on both the front and rear sides of the spring swivel seats, and two sets of positioning holes are opened on the surface of the spring swivel seats near the auxiliary crossbeam.

[0007] Furthermore, the main frame and the fixed base are integrated into a single structure, and the main frame, fixed base, spring swivel base, fixed corner bracket and positioning socket are arranged in an "H" shape.

[0008] Furthermore, the top of the stabilizing angle bracket and the bottom of the fixed base are provided with holes near the four opposite corners for bolt fixing. The spring telescopic rod and the assembly pile are set as an integrated structure.

[0009] Furthermore, the auxiliary crossbeam includes a side support, an assembly bracket, a guide rail, a movable seat, docking posts, and positioning bolts. The upper and lower surfaces of both ends of the side support are provided with assembly brackets, and the side surface of the side support near the auxiliary crossbeam is horizontally mounted with a guide rail. The surface of the guide rail is connected and mounted with a movable seat. The middle of the side surface of the movable seat near the auxiliary crossbeam is horizontally and integrally provided with two sets of docking posts. At the same time, positioning bolts are horizontally threaded and installed at both ends of the side surface of the movable seat near the auxiliary crossbeam.

[0010] Furthermore, the assembly bracket has holes for bolt fixing on four opposite corners on its vertical side.

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0018] like Figures 1 to 5As shown, an adaptive workpiece shape surface coating brushing device includes a supporting crossbeam 1 and a telescopic frame 3. Auxiliary crossbeams 2 are horizontally connected and installed at both ends of the supporting crossbeam 1. Seven sets of telescopic frame 3 are equidistantly arranged and vertically installed at the bottom of the supporting crossbeam 1. A brushing component 4 is installed at the bottom of the telescopic frame 3. The telescopic frame 3 includes a fixed frame 301, stabilizing angle brackets 302, spring telescopic rods 303, and mounting posts 304. Stabilizing angle brackets 302 are symmetrically installed on the left and right sides of the fixed frame 301, and a spring telescopic rod 303 is vertically installed in the middle of the fixed frame 301. A mounting post 304 is vertically installed at the bottom of the spring telescopic rod 303. The top of the stabilizing angle bracket 302 connects to the bottom of the fixed base 102 near the four... Holes for bolt fixing are provided at each diagonal point. The spring telescopic rod 303 and the assembly pile 304 are integrated into one structure. The supporting crossbeam 1 includes a main frame 101, a fixed seat 102, a spring swivel seat 103, fixed corner brackets 104, and positioning holes 105. Fixed seats 102 are evenly spaced at the bottom of the main frame 101, and spring swivel seats 103 are connected and installed at both ends of the main frame 101. Fixed corner brackets 104 are installed on both the front and rear sides of the spring swivel seat 103. Two sets of positioning holes 105 are provided on the surface of the spring swivel seat 103 near the auxiliary crossbeam 2. The main frame 101 and the fixed seat 102 are integrated into one structure. 03. The fixed angle bracket 104 and the positioning socket 105 are arranged in an "H" shape. Utilizing the elastic properties of the spring swivel seat 103, when the equipment is adjusted or subjected to external force, the spring swivel seat 103 undergoes a certain degree of elastic deformation, thereby buffering and dispersing the force and preventing damage to the equipment due to excessive localized stress. Simultaneously, when the external force disappears, the spring swivel seat 103 returns to its original shape, ensuring normal operation of the equipment. The fixed angle bracket 104 is bolted to the side surface of the movable seat 204 where the connecting pile 205 is located. This installation method makes the connection between the fixed angle bracket 104 and the movable seat 204 more stable. During equipment operation, the fixed angle bracket 104 can effectively transfer the force to the movable seat. On seat 204, to ensure the structural stability of the entire equipment, the inner surface structure of the positioning socket 105 matches the outer surface structure of the docking pile 205. This matching design allows the docking pile 205 to be accurately inserted into the positioning socket 105, achieving precise positioning and connection. During the painting operation, this ensures that the painting component 4 accurately reaches the designated position, improving the accuracy and quality of the painting. On the upper and lower surfaces of the left and right ends of the side support 201 in the auxiliary crossbar 2, there are assembly corner brackets 202. The vertical side of the assembly corner bracket 202 has holes near the four opposite corners for bolt fixing. Through these holes, the side support 201 can be easily fixed and connected to other components, enhancing the overall stability of the equipment.The guide rail 203 is horizontally mounted on the side surface of the side support 201 near the auxiliary crossbeam 2. The movable seat 204 is connected and mounted on the surface of the guide rail 203. The movable seat 204 and the guide rail 203 are connected and combined with each other using a slotted embedded structure. This structure allows the movable seat 204 to slide smoothly on the guide rail 203, reducing friction and shaking, and improving the stability of equipment operation. Two sets of docking posts 205 are horizontally and integrally set in the middle of the side surface of the movable seat 204 near the auxiliary crossbeam 2, and positioning bolts 206 are horizontally threaded at both ends. The docking posts 205 are used to dock with the positioning holes 105 on the support crossbeam 1, and the positioning bolts 206 are used to fix the connection after docking, ensuring the connection is firm. The brush seat 401 in the coating component 4 is threadedly connected to the assembly post 304 of the telescopic frame component 3 through the combination post 402. This threaded connection method is not only convenient for installation and disassembly, but also has a firm connection. When it is necessary to replace or repair the coating component 4, it can be operated quickly, improving work efficiency.

[0019] like Figures 1 to 5As shown, the auxiliary crossbeam 2 includes a side support 201, an assembly bracket 202, a guide rail 203, a movable seat 204, connecting posts 205, and positioning bolts 206. Assembly brackets 202 are installed on the upper and lower surfaces of both ends of the side support 201. A guide rail 203 is horizontally installed on the side surface of the side support 201 closest to the auxiliary crossbeam 2, and a movable seat 204 is connected to the surface of the guide rail 203. Two sets of connecting posts 205 are horizontally and integrally installed in the middle of the side surface of the movable seat 204 closest to the auxiliary crossbeam 2. Positioning bolts 206 are horizontally threaded at both ends of the side surface of the movable seat 204 closest to the auxiliary crossbeam 2. Holes for bolt fixing are provided near the four opposite corners on the vertical side of the assembly bracket 202. The movable seat 204 and the guide rail 203 are connected and combined using a slotted embedded structure. The fixed bracket 104 is bolted to the side surface of the movable base 204 where the docking post 205 is located. The inner surface structure of the positioning hole 105 matches the outer surface structure of the docking post 205. The coating component 4 includes a brush holder 401, a combination post 402, and a brush body 403. The combination post 402 is vertically positioned at the top center of the brush holder 401, and the brush body 403 is embedded in the bottom of the brush holder 401. The assembly post 304 and the combination post 402 are connected by threads. The brush body 403 is made of DuPont bristles made of high-performance polymer material. Utilizing the unique properties of DuPont bristles, the brush body 403 exhibits excellent wear resistance during coating. Even with prolonged friction with the workpiece surface, bristle breakage or shedding is unlikely, ensuring the continuity and stability of the coating process. Simultaneously, its corrosion resistance allows the brush body 403 to be used in various complex chemical environments without deterioration or damage from contact with chemicals, significantly extending its service life. Moreover, DuPont bristles are highly flexible, allowing them to conform well to the surface contours of workpieces of different shapes, ensuring even coating coverage and preventing uneven application or omissions, thus improving coating quality. In actual operation, when applying surface coatings to workpieces of different shapes and sizes, the position of the support frame 1 is first adjusted by sliding the movable seat 204 on the guide rail 203 according to the size and position of the workpiece, so that the coating component 4 is roughly in the appropriate working area. Then, the position of the support frame 1 is precisely determined by the docking of the connecting post 205 and the positioning socket 105 and the fixing of the positioning bolt 206, ensuring that the coating component 4 can accurately reach the designated position. Next, the spring telescopic rod 303 in the telescopic frame component 3 adaptively extends and retracts according to the contours of the workpiece surface, ensuring that the coating component 4 always maintains close contact with the workpiece surface, and the coating application begins. Throughout the process, the various components of the equipment work together seamlessly and operate stably, efficiently and with high quality completing the surface coating application tasks for different workpieces.

[0020] In summary, as Figures 1 to 5 As shown, the adaptive workpiece shape surface coating brushing equipment is used by first placing the equipment in a suitable working area, then structurally installing the auxiliary crossbeams 2 at both ends of the supporting crossbeam 1, and then firmly connecting the side bracket 201 with other fixed components through the hole structure on the mounting bracket 202 to ensure the stability of the overall structure of the auxiliary crossbeam 2. After that, the guide rail 203 is horizontally installed on the side surface of the side bracket 201 near the appropriate position to ensure the flatness of the guide rail 203 installation, laying the foundation for the smooth sliding of the subsequent moving seat 204. Next, the moving seat 204 is accurately connected and installed on the surface of the guide rail 203. Utilizing its slotted embedded structure, in conjunction with the use of the positioning bolt 206, the moving seat 204 and the guide rail 203 are tightly fitted to reduce shaking during operation. After the auxiliary crossbeam 2 is installed, the position of the movable seat 204 on the guide rail 203 will be initially adjusted according to the placement position and approximate size of the workpiece. This will allow the support crossbeam 1 to move the coating component 4 to a position close to the coating area of ​​the workpiece. The movable seat 204 will be fixed to the surface of the guide rail 203 by screwing the positioning bolt 206 to ensure that the position of the support crossbeam 1 is accurate and that the coating component 4 can be accurately aligned with the part of the workpiece to be coated. The supporting crossbeam 1, with its unique structural design, plays a crucial role in the operation of the equipment. The main frame 101 and the fixed base 102 are integrally formed, constructing a stable main frame and providing a solid foundation for the entire equipment. The spring swivel seat 103, with its elastic properties, can quickly undergo elastic deformation when the equipment is adjusted or subjected to external impact, effectively buffering and dispersing the force, preventing damage due to excessive localized stress. When the external force disappears, it quickly returns to its original shape, ensuring the equipment returns to normal operation. The fixed angle bracket 104 is securely bolted to the side surface of the movable base 204 where the connecting pile 205 is located. This installation method makes the connection between the fixed angle bracket 104 and the movable base 204 extremely strong. During equipment operation, the fixed angle bracket 104 can efficiently transfer the force to the movable base 204, effectively ensuring the structural stability of the entire equipment. After the equipment is started, the telescopic frame component 3 comes into play. The spring telescopic rod 303 inside it automatically extends and retracts according to the undulations of the workpiece surface. Since the spring telescopic rod 303 and the assembly pile 304 adopt an integrated structure, the possible failure of the connection point is reduced, and the smoothness and stability of the adjustment process are ensured. As the spring telescopic rod 303 extends and retracts, the coating component 4 moves up and down accordingly, always closely adhering to the workpiece surface. The brush body 403 in the coating component 4 exhibits excellent properties thanks to the high-performance polymer material DuPont bristles it uses. During the coating process, the wear resistance of the DuPont bristles allows the brush body 403 to withstand repeated friction with the workpiece surface without easily being damaged, ensuring the continuity of long-term coating work. Its corrosion resistance allows the brush body 403 to work normally in various chemical environments without deteriorating due to contact with the chemical components in the coating, thus extending its service life. Its flexibility allows the brush body 403 to adapt well to workpiece surfaces of different shapes, whether flat, curved, or irregular, ensuring that the coating is applied evenly and that the coating quality is uniform. Throughout the coating process, the supporting crossbeam 1, auxiliary crossbeam 2, and telescopic frame 3 work together closely and operate stably. Through this adaptive adjustment method and the coordinated work of each component, the equipment can efficiently and effectively complete the surface coating task of workpieces of different shapes and sizes, greatly improving production efficiency and product quality, and reducing labor costs and equipment maintenance costs.
