Description

Technical Field

[0001] This utility model relates to the field of metal spraying technology, specifically to a metal connector spraying device. Background Technology

[0002] Metal connectors (such as bolts, flanges, fasteners, etc.) are core basic components in fields such as machinery manufacturing, construction engineering, and marine equipment. Surface coating treatment is a key aspect in ensuring their service life and performance. However, most traditional spraying fixtures are fixed and rigid structures that can only accommodate single-specification connectors. When faced with multiple batches and sizes of production tasks, frequent manual fixture changes are required, which not only increases the production time per batch but also easily leads to workpiece positioning deviation due to fixture disassembly and assembly errors, directly affecting coating adhesion and spraying accuracy. Furthermore, the spraying pipe and workpiece bearing structure of most equipment are fixed in position, making it impossible to flexibly adjust their relative posture according to the irregular structure of the connector. This easily creates spraying blind spots for areas such as threaded grooves and corners. At the same time, the lack of a stable moving and adjusting mechanism for the workpiece leads to localized paint accumulation, resulting in color differences and a low finished product qualification rate.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0019] Example 1 Reference Figure 1-4The first embodiment of this utility model adopts the following technical solution, including a workbench 1, an operation plate 2 fixedly installed on the top of the workbench 1, a gantry frame 3 fixedly installed on the top of the operation plate 2, two sets of spray pipes 4 slidably installed on the top of the gantry frame 3, an inlet pipe 41 fixedly connected to the top of the spray pipes 4, the inlet pipe 41 being connected to an external spray box, a shaft frame 66 slidably installed on the top of the operation plate 2, and a support plate 63 and a support plate 64 for placing metal connectors respectively provided above the shaft frame 66, and also includes an angle adjustment mechanism, which is set on the top of the operation plate 2 and is used to adjust the angle of the support plate 63 and the support plate 64.

[0020] Specifically, how to perform spraying is existing technology and a common technique used by those skilled in the art, and is not a technical problem solved by this application, so it will not be elaborated upon. The workbench 1 and the operating panel 2 provide the foundation for bearing and operation. The gantry 3 provides support and guidance for the sliding of the spraying pipe 4. The support plate 1 63 and support plate 2 64 above the shaft frame 66 adopt a symmetrical design. Through the angle adjustment mechanism, the distance between the two can be finely adjusted according to the size of the metal connectors to ensure that workpieces of different specifications can be placed stably. The liquid inlet pipe 41 serves as the conveying channel for the spraying material. One end is connected to the booster pump of the external spraying box, and the other end is fixedly connected to the top of the spraying pipe 4. Before the spraying starts, the external spraying box pressurizes the paint through the booster pump and then delivers it to the inside of the spraying pipe 4 through the liquid inlet pipe 41. Then, the atomizing nozzle at the bottom of the spraying pipe 4 opens, thereby spraying the metal connectors placed on the support plate 1 63 and support plate 2 64.

[0021] Example 2 The second embodiment of this utility model adopts the following technical solution: a groove 5 is provided on the top of the gantry frame 3, and a T-shaped slider 51 is fixedly installed on the surface of the spray pipe 4. The T-shaped slider 51 and the groove 5 slide with clearance. The angle adjustment mechanism includes a stepper motor 6, a forward and reverse lead screw 61, a screw sleeve 62, and a fixed shaft 651. A support plate 63 and a support plate 64 are rotatably installed by a shaft pin. The two ends of the forward and reverse lead screw 61 are rotatably installed with the shaft frame 66. The output end of the stepper motor 6 is fixedly installed with the left end of the forward and reverse lead screw 61. Fixing members 65 are fixedly installed on the opposite sides of the support plate 63 and the support plate 64. The screw sleeve 62 is threadedly connected to the surface of the forward and reverse lead screw 61. The fixed shaft 651 is fixedly installed inside the screw sleeve 62. The fixing member 65 is rotatably installed on the surface of the fixed shaft 651.

[0022] Specifically, the operator directly pushes the body of the spray pipe 4, causing the T-shaped slider 51 to slide within the groove 5 in the direction of the thrust, thereby adjusting the position of the spray pipe 4. When it is necessary to adjust the angle between the second support plate 64 and the first support plate 63, the stepper motor 6 is started to drive the forward and reverse lead screws 61 to rotate. The forward and reverse lead screws 61 can drive the threaded sleeves 62 on both sides of the surface to move closer and further apart. When the threaded sleeves 62 move closer to each other, the fixing shaft 651 can drive the fixing part 65 to push the corresponding upper support plate 64 and the first support plate 63 against each other, causing the support plate 63 and the second support plate 64 to rotate around the hinged shaft pin to produce a small angle adjustment. Similarly, when it is necessary to reverse the above steps, the support plate 64 and the first support plate 63 can rotate around the hinged shaft pin to produce a large angle change.

[0023] Example 3 The third embodiment of this utility model adopts the following technical solution: the top of the operation plate 2 is provided with a longitudinally opened mounting groove, the front side of the operation plate 2 is fixedly installed with a servo motor 7, a lead screw 71 is provided in the mounting groove at the top of the operation plate 2, the lead screw 71 is fixedly installed with the output end of the servo motor 7, the surface of the lead screw 71 is threadedly connected with a screw sleeve 72, the top of the screw sleeve 72 is fixedly installed at the center of the bottom of the shaft frame 66, the front and rear sides of the support plate 1 63 and the support plate 2 64 opposite to each other are fixedly installed with a collection hopper 641, the front side of the collection hopper 641 is fixedly connected with a drain hose 81, the left and right sides of the workbench 1 are provided with a collection box 8, and the end of the drain hose 81 away from the collection hopper 641 is fixedly connected with the collection box 8.

[0024] Specifically, the mounting groove allows the threaded sleeve 72 to slide back and forth stably. When the shaft bracket 66 needs to be moved back and forth, the servo motor 7 drives the screw 71 fixed to it to rotate. The screw 71 drives the threaded sleeve 72, which is threaded to it, to slide back and forth inside the mounting groove. The sliding of the threaded sleeve 72 can drive the shaft bracket 66 to slide back and forth, so that the support plate 64 and support plate 63 installed on the top of the shaft bracket 66 can be evenly sprayed on the top connecting parts. The drain hose 81 allows the paint inside the collection hopper 641 to flow into the collection box 8 for collection. Since the drain hose 81 is soft, it can easily follow the support plate 63 back and forth without breaking, ensuring collection stability.

[0025] Working principle: The workbench 1 provides the foundation for the entire equipment, the control panel 2 serves as the direct operating platform, the gantry 3 on it provides sliding support for the spray pipe 4, and the shaft frame 66 supports the support plate 1 63 and the support plate 2 64, forming the core area for placing the workpiece. According to the size of the metal connector to be sprayed, the stepper motor 6 in the angle adjustment mechanism is started. The output end of the stepper motor 6 drives the forward and reverse lead screw 61 to rotate forward or reverse on the shaft frame 66, causing the threaded sleeve 62 connected to it to move axially (closer or farther away) along the forward and reverse lead screw 61. The threaded sleeve 62 drives the fixing member 65 on the support plate 63 and the support plate 64 through the internal fixed shaft 651. Since the support plate 63 and the support plate 64 are rotatably connected by the shaft pin, under the action of the thrust or pull of the fixing member 65, the support plate 63 and the support plate 64 rotate relative to each other around the shaft pin. When the threaded sleeve 62 approaches When the angle between the two support plates decreases and the distance between them narrows, it is suitable for small workpieces. When the first screw sleeve 62 moves away from the workpiece, the angle increases and the distance between them widens, making it suitable for large workpieces and ultimately achieving stable placement of the workpiece. At the same time, in order to ensure uniform spraying, the servo motor 7 on the front side of the operation panel 2 is started. The servo motor 7 drives the lead screw 71 in the mounting groove to rotate, causing the second screw sleeve 72, which is threaded to it, to slide back and forth along the mounting groove. Since the second screw sleeve 72 is fixed to the bottom of the shaft bracket 66, the shaft bracket 66 moves back and forth synchronously with the second screw sleeve 72, thereby driving the metal connectors on the first support plate 63 and the second support plate 64 to move, thus avoiding local paint accumulation during the spraying process. The spray pipe 4 is manually pushed so that the T-shaped slider 51 on the surface of the spray pipe 4 slides along the gap of the slide groove 5 at the top of the gantry 3. The lateral spacing of the two sets of spray pipes 4 is adjusted to ensure that the atomizing nozzles cover the entire surface of the workpiece. Then, the booster pump of the external spray box pressurizes the paint and delivers it to the inside of the spray pipe 4 through the liquid inlet pipe 41. After the paint is atomized by the atomizing nozzle at the bottom of the spray pipe 4, it is evenly sprayed onto the surface of the moving metal connector. During this process, the workpiece moves at a constant speed with the shaft frame 66 and the position of the spray pipe 4 is fixed, so as to achieve full-surface spraying of the workpiece without blind spots. During the spraying process, the atomized paint that does not adhere to the surface of the workpiece drips into the collection hopper 641 on the opposite side of the support plate 63 and the support plate 64 under the action of gravity. The collection hopper 641 transports the residual paint to the collection boxes 8 on both sides of the workbench 1 through the drain hose 81 on the front side, thus completing the paint recovery. At the same time, the flexible characteristics of the drain hose 81 allow it to deform flexibly with the movement of the support plate 63 and the support plate 64 or the shaft 66, avoiding damage and ensuring a stable and leak-free recovery process.

[0026] In summary, the combination of the workbench, control panel, gantry frame, spray pipe, liquid inlet pipe, shaft frame, support plate one, support plate two, and angle adjustment mechanism solves the problems of poor adaptability, low production efficiency, and unstable spray quality of traditional spraying fixtures.
