Description

Technical Field

[0001] This utility model relates to the field of masking tooling technology, and in particular to a high-efficiency spraying masking tooling for electrical cabinet production. Background Technology

[0002] Electrical cabinet manufacturing spraying is a process of coating the surface of electrical cabinets, mainly including pretreatment, spraying, and curing steps. Common methods include electrostatic powder coating and liquid spraying, which can improve the corrosion resistance, rust prevention, and wear resistance of electrical cabinets, as well as enhance their aesthetics. The quality of spraying is affected by surface treatment, environmental conditions, and process parameters, and it is widely used in power, communication, transportation, and industrial automation fields. Masking fixtures are required during the spraying process.

[0003] Spray masking fixtures use materials such as rubber, plastic, or metal covers to shield specific areas of a workpiece, preventing paint from adhering to these areas during the spraying process. By ensuring that paint only covers the required areas, spray masking fixtures improve coating accuracy, reduce waste, and optimize spraying quality, and are widely used in the spraying process of complex workpieces.

[0004] Existing masking fixtures are inconvenient to adjust or replace during use, or require additional tools to complete the replacement, resulting in reduced processing efficiency. Therefore, a high-efficiency spray masking fixture for electrical cabinet production is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3This utility model provides an embodiment of a high-efficiency spraying and masking fixture for electrical cabinet production, comprising a frame 1, with a support rod 2 fixedly connected to the inner wall of the frame 1. The support rod 2 securely mounts each key component on the inner wall of the frame 1, providing a reliable reference for subsequent rotation and positioning. Two rotating sleeves 3 are rotatably connected to the outside of the support rod 2. The two rotating sleeves 3 are connected through the support rod 2, realizing smooth rotational transmission, so that the subsequent rotating frame 4 can rotate at a predetermined angle. A rotating frame 4 is fixedly connected to one side of the two rotating sleeves 3. The rotating frame 4 realizes the function of adjustment and positioning by means of the rotation of the rotating sleeves 3.

[0033] A motor 5 is fixedly connected to the top of the rotating frame 4. The motor 5, installed on the top of the rotating frame 4, provides sufficient driving force for the subsequent start of the rotating rod 6 through power transmission, ensuring that the position of the masking plate 10 can be adjusted in time during the spraying operation. The driving end of the motor 5 is fixedly connected to the rotating rod 6. The rotating rod 6 relies on the drive of the motor 5 to quickly transmit rotational motion after starting, thereby driving the extension plates 7 fixed on both sides to swing synchronously, assisting in the overall positioning and adjustment of the equipment. Extension plates 7 are fixedly connected to both sides of the rotating rod 6. The extension plates 7 adopt a double-sided fixed connection structure to ensure that the motion is transmitted evenly under the drive of the rotating rod 6, so that the mounting plate 8 can accurately respond to the motion and realize the coordinated movement of the subsequent stabilizing plate 9.

[0034] The other end of the extension plate 7 is fixedly connected to the mounting plate 8. After the mounting plate 8 is connected to the extension plate 7, it can transmit power to the stabilizing plate 9 when the extension plate 7 swings, thereby causing the stabilizing plate 9 to accurately apply fixing pressure to the masking plate 10, ensuring that the spraying area is correctly positioned. The stabilizing plate 9 is fixedly connected to one side of the mounting plate 8. The stabilizing plate 9 adjusts its position during the movement by relying on the mounting plate 8. When it pushes the masking plate 10, it can ensure that the masking plate 10 remains parallel and stable, thereby effectively preventing the electrical cabinet plate 12 from moving during spraying. The top of the frame 1 is provided with the masking plate 10. The masking plate 10 is set at the top of the frame 1 and plays the role of isolating the area that does not need to be sprayed. Its fixation has a decisive effect on ensuring accurate masking of the electrical cabinet plate 12 during spraying. The outside of the masking plate 10 is provided with a groove. The groove design allows the masking plate 10 to be quickly disassembled or replaced with different styles when necessary, thereby meeting the needs of diverse spraying processes, while ensuring that it can fit tightly with the support plate 14 during installation.

[0035] A workbench 11 is fixedly connected to the bottom inner wall of frame 1. The workbench 11 is firmly connected to the bottom inner wall of frame 1 to ensure reliable foundation support for subsequent fixing processes. An electrical cabinet plate 12 is installed on the top of the workbench 11. The electrical cabinet plate 12, as the object to be sprayed, is accurately placed on the workbench 11. A torque spring 15 is fixedly connected to one side of the rotating sleeve 3. The torque spring 15, through its fixed connection with the rotating sleeve 3, provides a reverse elastic force during rotation, enabling the rotating frame 4 to lock its position more quickly and stably when adjusted to a parallel state. The other end of the torque spring 15 is fixedly connected to one side of frame 1. This fixing method allows the torque spring 15 to transfer elastic potential energy to frame 1 when subjected to rotation, assisting in stabilizing the docking state between the rotating frame 4 and the subsequent fixing plate 20, thereby ensuring that the electrical cabinet plate 12 does not shift due to vibration.

[0036] refer to Figure 1 and Figure 4 A mounting component is provided on one side of the rotating sleeve 3. The mounting component is designed to facilitate quick locking after the rotating frame 4 is rotated to the predetermined parallel position, thereby providing accurate initial positioning conditions for fixing the extension block 23 with bolts 24.

[0037] The mounting assembly includes two limiting rings 21. These two limiting rings 21 are crucial components of the mounting assembly. By restricting the range of motion of the rotating rings 22, they ensure the rotating frame 4 is precisely fixed during rotation, thus aiding in the stable positioning of the electrical cabinet panel 12. The two limiting rings 21 are respectively fixedly connected to both sides of one end of the rotating frame 4. The limiting rings 21 fixed to both sides of the rotating frame 4 ensure balanced force during rotation and work in conjunction with the rotating rings 22 to accurately constrain the external of the fixing rod 13, laying the foundation for precise alignment of the electrical cabinet panel 12 before spraying. Two rotating rings 22 are rotatably connected to one side of the rotating frame 4. The rotating rings 22 are attached to one side of the rotating frame 4 and, through engagement with the limiting rings 21, can quickly achieve external alignment with the fixing rod 13 after the motor 5 is started. The tight connection between the limiting ring 21 and the rotating ring 22 locks the position of the rotating frame 4, providing conditions for applying fixing force to the fixing plate 20. The other end of the limiting ring 21 and the rotating ring 22 are fixedly connected to the extension block 23. The fixed connection of the extension block 23 allows the limiting ring 21 and the rotating ring 22 to provide additional stable support when they contact the fixing rod 13. After being locked with bolts 24, it is ensured that the rotating frame 4 does not shake when it is fixed, thereby ensuring the spraying accuracy of the electrical cabinet plate 12. The inner wall of the two extension blocks 23 is threaded with bolts 24. The bolts 24 firmly lock the extension blocks 23 together through the inner wall threads, playing a key role in the entire fixing process, making the connection between the rotating frame 4 and the fixing rod 13 more stable, thereby ensuring that the fixing plate 20 can effectively transmit the fixing force to the electrical cabinet plate 12.

[0038] A fixing rod 13 is fixedly connected to the inner wall of the frame 1. The fixing rod 13 is fixed to the inner wall of the frame 1 as a reference. Its contact design with the limiting ring 21 and the rotating ring 22 allows the rotating frame 4 to be accurately aligned after adjustment, thereby providing stable support for the spraying and fixing of the electrical cabinet plate 12. The side of the limiting ring 21 and the rotating ring 22 that is close to each other is in contact with the outside of the fixing rod 13. This structural design allows the fixing rod 13 to effectively cooperate with the limiting ring 21 and the rotating ring 22 throughout the fixing process to achieve precise constraint on the position of the rotating frame 4, thereby ensuring that the fixing plate 20 applies a balanced fixing force when it contacts the electrical cabinet plate 12.

[0039] A fixing component is fixedly connected to the bottom of the rotating frame 4. The fixing component is installed at the bottom of the rotating frame 4 and plays the role of auxiliary support and fixing the rotating frame 4. After the electrical cabinet plate 12 is placed on the workbench 11, the fixing plate 20 can be subjected to continuous and stable pressure through the fixing component to ensure accurate spraying positioning. The fixing component includes two support plates 14. The two support plates 14 are the main load-bearing elements of the fixing component and provide a solid support for the masking plate 10, thereby ensuring that the masking plate 10 can remain stable and parallel during the spraying process, and thus shielding the non-spraying area of ​​the electrical cabinet plate 12. The two support plates 14 are fixedly connected to the bottom sides of the rotating frame 4 respectively. The support plates 14 fixed to the sides of the rotating frame 4 respectively ensure the overall force balance. When the masking plate 10 is in contact with the support plate 14, they can jointly prevent displacement caused by equipment vibration and ensure the stability of the workpiece during spraying.

[0040] The bottom of the stabilizing plate 9 contacts the top of the masking plate 10. When the stabilizing plate 9 moves under the drive of the mounting plate 8, it makes close contact with the top of the masking plate 10, which plays an auxiliary role in fixing the masking plate 10. This ensures that the masking plate 10 is always in the correct position during the spraying process and will not affect the spraying effect due to swinging. The bottom of the masking plate 10 contacts the top of the two support plates 14. This structural design ensures that after the masking plate 10 is installed on the top of the frame 1, it obtains sufficient support through close contact with the support plates 14. This effectively isolates the area that does not need to be sprayed during the spraying operation and avoids errors caused by displacement. The bottom sides of the support plates 14 are fixedly connected to the housings 16. The housings 16 are installed on the bottom sides of the support plates 14 to protect the internal structure.

[0041] A telescopic spring 17 is fixedly connected to the inner wall of the housing 16. The telescopic spring 17 is attached to the inner wall of the housing 16 and can be appropriately squeezed when the fixing plate 20 contacts the electrical cabinet plate 12, thereby generating elastic potential energy and providing continuous fixing pressure for the electrical cabinet plate 12 to avoid deviation during the spraying process. A sliding plate 18 is fixedly connected to the bottom of the telescopic spring 17.

[0042] A connecting post 19 is fixedly connected to the bottom of the sliding plate 18. The connecting post 19 is fixedly connected to the sliding plate 18, and a fixing plate 20 is fixedly connected to the other end of the connecting post 19. The fixing plate 20 is the component that finally contacts the electrical cabinet plate 12. Through the pressure transmitted from the connecting post 19, it reliably presses the electrical cabinet plate 12, thereby preventing processing errors caused by deviation during the spraying process.

[0043] The sliding plate 18 is externally slidably connected to the inner wall of the housing 16. This external sliding connection design allows the sliding plate 18 to flexibly adjust its position during the fixing process, ensuring that when the telescopic spring 17 is compressed, the connecting post 19 and the fixing plate 20 can accurately contact the electrical cabinet plate 12 and play a stable fixing role. The external sliding connection of the connecting post 19 is located at the bottom of the housing 16. The sliding connection structure of the connecting post 19 at the bottom of the housing 16 ensures that it moves smoothly and without obstruction when transmitting the pressure of the telescopic spring 17, so that the fixing plate 20 can make stable contact with the electrical cabinet plate 12, ensuring that the entire fixing process is continuous and effective. The bottom of the fixing plate 20 contacts the top of the electrical cabinet plate 12. After the fixing plate 20 contacts the top of the electrical cabinet plate 12, it achieves continuous compression through the elastic potential energy generated by the telescopic spring 17, ensuring that the electrical cabinet plate 12 will not shift due to external interference during the spraying process, thereby achieving the purpose of high-precision spraying.

[0044] Working principle: When the equipment is needed, place the electrical cabinet plate 12 to be sprayed on top of the workbench 11. Then rotate the rotating frame 4, which will drive the rotating sleeve 3 to rotate outside the support rod 2. Rotate the rotating frame 4 until it is parallel. Then rotate the rotating ring 22 so that the rotating ring 22 fits with the limiting ring 21 and is fitted outside the fixed rod 13. Then fix the two extension blocks 23 with bolts 24 to complete the fixation of the rotating frame 4. During this fixing process, the fixing plate 20 will contact the electrical cabinet plate 12. At this time, the fixing plate 20 will push the connecting column 19, and the connecting column 19 will push the sliding plate 18 to compress the telescopic spring 17, thereby causing the telescopic spring 17 to deform and generate elastic potential energy. Through the elastic potential energy, the fixing plate 20 will press against the electrical cabinet plate 12 to fix the electrical cabinet plate 12 and prevent it from shifting during spraying, which would cause processing errors.

[0045] At this point, the shielding plate 10 is placed on top of the two support plates 14. The motor 5 is then started, which drives the rotating rod 6 to rotate. The rotation of the rotating rod 6 causes the extension plate 7 to swing. The swing of the extension plate 7 causes the mounting plate 8 to push the stabilizing plate 9 to move. The stabilizing plate 9 then holds the shielding plate 10 in place, thus fixing the shielding plate 10 in place. The electrical cabinet panel 12 can then be sprayed with a spraying machine. The shielding plate 10 can be disassembled and replaced with different styles as needed, facilitating various spraying styles for the electrical cabinet panel 12.
