Description

Technical Field

[0001] This utility model relates to the field of coating technology, specifically a coating fixture with fine-tuning function. Background Technology

[0002] Coating is an important industrial process that alters the properties and characteristics of materials by depositing thin films on their surfaces. It is widely used in fields such as optics, electronics, and corrosion protection. The main types include physical vapor deposition (PVD), chemical vapor deposition (CVD), solution deposition, and electroplating. Coating can improve the wear resistance, corrosion resistance, and electrical conductivity of materials, while also improving optical performance and extending product lifespan.

[0003] Upon investigation, a Chinese utility model discloses a coating fixture (publication number: CN220685233U), which includes a fixed frame; two pairs of elastic connectors, each pair of elastic connectors being disposed on two opposite sides of the fixed frame, the two pairs of elastic connectors being arranged opposite each other, one end of each elastic connector being used to connect with the side frame, and the other end being used to connect with a corresponding positioning hole on the coating object.

[0004] While the aforementioned patent can reduce the clamping contact area between the coating fixture and the object to be coated, achieving 100% coating on both sides of the object in one go, thus expanding the coating area and ensuring the integrity and quality of the coating; it can also be used for clamping objects of various sizes; and the structure of the fixing frame and elastic connector is simple, making clamping convenient and efficient, thus improving clamping efficiency. However, the position adjustment of the elastic connector is too fixed, allowing only one-step adjustments, which is not convenient for fine-tuning and has low adjustment precision. This may lead to inaccurate alignment of the positioning holes, thereby affecting the uniformity and quality of the coating. In addition, when handling objects with complex shapes or small objects to be coated, the fixture may cause excessive stretching of the elastic connector, resulting in excessive tension on the object to be coated and causing damage.

[0005] Therefore, this utility model provides a coating fixture with fine-tuning function to solve the above problems. Utility Model Content

[0025] 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.

[0026] This utility model provides a coating fixture with fine-tuning function, such as Figures 1-4 As shown, a coating fixture with fine-tuning function includes a stand 1. A circular groove is opened on the inner side of the stand 1. A rotating rod 2 is rotatably connected inside the circular groove. A sliding rod 3 is fixedly connected to one end of the rotating rod 2. Connecting blocks 4 are fixedly connected to both ends of the sliding rod 3. An adjustment component is rotatably connected inside the connecting blocks 4.

[0027] The adjustment assembly includes a first threaded rod 5, one side of the outer surface of the first threaded rod 5 is rotatably connected to the inside of the connecting block 4, and a sliding block 6 is threadedly connected to the outer surface of the first threaded rod 5. A threaded groove is opened on one side of the sliding block 6, and a second threaded rod 7 is threadedly connected inside the threaded groove. Twisting the first threaded rod 5 causes the sliding block 6 to move on its outer surface, which can arbitrarily adjust the position of the elastic connector 10. The adjustment accuracy is high and the adaptability is strong. It can be accurately aligned with the positioning hole to avoid affecting the uniformity and quality of the coating. Then, by twisting the second threaded rod 7, the distance between the elastic connector 10 and the coating object is adjusted, so as to reasonably stretch and fix the coating objects of different shapes and sizes, which can avoid excessive tension and damage to the coating object.

[0028] One end of the second threaded rod 7 is rotatably connected to a fixed block 8 via a rotating rod. A mounting block 9 is rotatably connected to one side of the fixed block 8. A through groove is provided on one side of the mounting block 9, and an elastic connector 10 is rotatably connected inside the through groove. The rotatable connection between the fixed block 8 and the second threaded rod 7 allows the elastic connector 10 to tilt left and right, increasing the flexibility of the connection. The rotatable connection between the fixed block 8 and the mounting block 9 allows the distance between the elastic connector 10 and the coating object to be adjusted by rotating the second threaded rod 7 even when the elastic connector 10 is connected to the coating object.

[0029] The outer surface of the sliding rod 3 is provided with a groove that matches the sliding block 6. Both ends of the inner side of the sliding rod 3 are fixedly connected with a crossbar 11. The sliding block 6 slides inside the groove to limit and guide the sliding block 6 so that it can move horizontally along the first threaded rod 5. The crossbar 11 connects the sliding rods 3 on both sides to ensure the stability when fixing the coating object.

[0030] A telescopic rod 12 is fixedly connected to one end of the outer side of the sliding rod 3, and a suction cup 13 is fixedly connected to one end of the telescopic rod 12. When the sliding rod 3 is at a suitable tilt angle, the telescopic rod 12 is extended so that the suction cup 13 is attached to the inner side of the stand 1 to fix the tilt angle of the sliding rod 3 and prevent it from rotating on its own.

[0031] The circular groove is located at the center of the stand 1, and both ends of the sliding rod 3 are within the circumference of the stand 1. The sliding rod 3 is within the circumference of the stand 1, which makes it easy to effectively fix the suction cup 13 at any position on the side of the stand 1, so that the sliding rod 3 can be tilted at any angle.

[0032] The elastic connector 10 consists of a connecting ring, a spring, and a hook. The connecting ring is rotatably connected inside the through groove. One end of the connecting ring is fixedly connected to the spring, and the other end of the spring is fixedly connected to the hook. The hook is hooked inside the positioning hole of the object to be coated. The connecting ring allows the hook to move up and down to accommodate a small range of tilting. The spring allows the hook to exert a pulling force on the object to be coated in order to fix the object to be coated.

[0033] Working steps: First, the first threaded rod 5 is screwed to move the sliding block 6 on its outer surface, allowing the position of the elastic connector 10 to be adjusted arbitrarily. Next, the second threaded rod 7 is screwed to adjust the distance between the elastic connector 10 and the object to be coated. Then, the hook is connected to the positioning hole of the object to be coated. Next, the tilt angle of the sliding rod 3 is adjusted with the rotating rod 2 as the center. Finally, the telescopic rod 12 is extended so that the suction cup 13 is attached to the inside of the stand 1 to fix the tilt angle of the sliding rod 3.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
