Technical Field

[0001] This utility model relates to the field of vacuum coating technology for hardware products, specifically a stable clamping device for vacuum coating of hardware products. Background Technology

[0002] Vacuum coating is an important aspect of vacuum applications. Based on vacuum technology, it utilizes physical or chemical methods and incorporates a range of new technologies such as electron beams, molecular beams, ion beams, plasma beams, radio frequency, and magnetron sputtering to provide a new process for thin film preparation for scientific research and practical production. Simply put, vacuum coating is the method of evaporating or sputtering metals, alloys, or compounds in a vacuum, causing them to solidify and deposit on a substrate (or base material).

[0003] Hardware fittings refer to machine parts or components made of hardware materials, as well as some small hardware products. During the manufacturing process, these fittings typically require vacuum coating technology to improve their surface properties. However, the diverse shapes and sizes of hardware fittings present challenges for clamping during the vacuum coating process.

[0004] Currently, most vacuum coating clamping devices on the market use simple mechanical clamping methods, such as clamping from the top and bottom or from the left and right sides. This clamping method has the following problems:

[0005] Insecure clamping: Due to the limited number of clamping points, the workpiece is prone to loosening during vacuum coating, which affects the coating effect.

[0006] Limited applicability: The single clamping method is difficult to adapt to hardware accessories of different shapes and sizes, resulting in poor clamping effect.

[0007] Complex operation: Manually adjusting the clamping position is time-consuming and labor-intensive, increasing production costs. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] like Figure 1-4 As shown, the sturdy clamping device for vacuum coating of hardware products of this utility model includes a support rod 1, on which a plurality of clamping components are provided. Each clamping component includes a fixing bolt 2, a bracket 3 and a fixing plate 4. The bracket 3 and the fixing plate 4 are connected by the fixing bolt 2. The bracket 3 is fixedly installed on the support rod 1, and an installation rod 5 is fixedly connected to the fixing plate 4.

[0028] like Figure 2-3 As shown, a control box 6 is fixedly connected to the mounting rod 5. A slider 7 is slidably connected inside the control box 6, and a clamping head 8 is detachably connected to the slider 7. A limit rod 9 is fixedly connected to the inner wall of the control box 6. The slider 7 is slidably sleeved on the limit rod 9, and a compression spring 10 is sleeved on the limit rod 9.

[0029] like Figure 2-3As shown, a connecting block 11 is fixedly connected to the mounting rod 5, and a lever 12 is rotatably connected to the connecting block 11. One end of the lever 12 is fixedly connected to a connecting rod 13. A turntable 14 is rotatably connected to the mounting rod 5, and an arc-shaped groove 15 is formed on the turntable 14. One end of the connecting rod 13 extends into the interior of the arc-shaped groove 15. Three levers 12, three connecting rods 13, and three arc-shaped grooves 15 are provided, arranged in a circular array around the mounting rod 5. The angle between the lever 12 and the connecting rod 13 is an obtuse angle. This design allows the movement of the connecting rod 13 to be more effectively converted into the oscillation of the lever 12. The connecting rod 13 is cylindrical.

[0030] like Figure 2-3 As shown, the lever 12 has a first limiting groove 16, the slider 7 has a fixedly connected to a lever block 17, and the control box 6 has a second limiting groove 18. The end of the lever block 17 away from the slider 7 passes through the second limiting groove 18 and extends into the interior of the first limiting groove 16. The first limiting groove 16 on the lever 12 and the second limiting groove 18 on the control box 6 ensure that the lever block 17 can stably transmit force when the slider 7 moves, preventing the slider 7 from deviating during movement.

[0031] Working principle:

[0032] When using this device, the angle of the clamping assembly needs to be adjusted according to the actual shape of the workpiece. The angle of the fixing plate 4 is adjusted, and then the angle of the fixing plate 4 is fixed and limited by the fixing bolts 2. Then, the turntable 14 is rotated manually or electrically. The turntable 14 is fixed on the mounting rod 5 and has an arc-shaped groove 15. When the turntable 14 rotates, the connecting rod 13 moves along the arc-shaped groove 15. One end of the connecting rod 13 is fixedly connected to the lever 12, and the other end extends into the arc-shaped groove 15. The movement of the connecting rod 13 drives the lever 12 to rotate around the connecting block 11. The angle between the lever 12 and the connecting rod 13 is an obtuse angle to ensure that the movement of the connecting rod 13 can be effectively transmitted to the lever 12. The swing of the lever 12 drives the slider 7 to slide along the limiting rod 9 through the lever block 17. When slider 7 slides, compression spring 10 is compressed, providing a certain elastic force, thereby opening the three clamping heads 8. Then, the hardware parts are placed into the clamping space, and the turntable 14 is released. Under the restoring action of the spring, slider 7 moves, causing the clamping heads 8 to clamp the hardware parts. The design of the clamping heads 8 can be adjusted according to the shape and size of the hardware parts to ensure a firm clamping. The elastic force of compression spring 10 ensures that the clamping heads 8 apply appropriate clamping force to the hardware parts, preventing loosening during vacuum coating. Three control boxes 6 are provided, located at different positions on the mounting rod 5, forming an array. This enables multi-point clamping of the hardware parts, ensuring a more stable clamping. Then, the support rod 1 is lifted to place the clamped hardware parts into the furnace for vacuum coating.

[0033] By controlling the rotation of turntable 14, the clamping process can be automated. The rotation of turntable 14 can be driven by an electric motor, reducing manual intervention and improving production efficiency.
