However, corrosion and poor thermal stability are two major problems that need to be addressed in sintered neodymium-iron-boron magnet applications.

At present, the adoption of a vacuum coating technology to deposit a corrosion-resistant protective coating on the surface of a magnet and a heavy rare earth coating are effective means for improving the corrosion resistance and the thermal stability of the magnet. The clamp is an important mechanical component in the vacuum coating technology, and is mainly used for fixing a sample in the coating process so as to ensure that the coating deposition is finished on the surface of the sample. Currently, a vertical vacuum coating machine is the most commonly used equipment for vacuum coating. However, in the actual production process, the variety of the overall dimensions of the sintered neodymium-iron-boron magnet is limited, the universality and flexibility of the clamp are poor, and the appearance of the magnet is usually required to be designed and processed independently, so that the production cost is greatly increased. Therefore, there is a need to develop a vertical vacuum coating fixture that is not limited by the external dimensions of the magnet to reduce the vacuum coating cost.

Detailed Description

Other advantages and advantages of the present utility model will become apparent to those skilled in the art from the following detailed description, which, by way of illustration, is to be read in connection with certain specific embodiments, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The following is a further description of specific examples.

As shown in fig. 1-4, the present utility model provides a multi-stage load-bearing vertical clamp for vacuum coating.

As shown in fig. 1, it mainly includes a main body portion (corresponding to the vertical diagonal column 1 in fig. 1) shaped like an umbrella (i.e., formed into a truncated cone structure) and an accessory portion (corresponding to the placement ring 2 in fig. 1). Wherein the main body part is a cone (i.e. a vertical inclined column 1) in a horn shape, and the outer surfaces of the cone are respectively sleeved with circular rings (i.e. a placing ring 2) with different sizes. The ring and the cone are directly fixed by means of interference fit. In the vacuum coating process, the magnet to be coated is placed on the circular ring and is back against the outer surface of the cone, and the magnet to be coated can be fixed by means of friction force between the bottom of the magnet to be coated and the circular ring. The placement surface 3 may be an anti-slip surface to further increase friction, and the anti-slip surface may be provided in any manner as will be understood by those skilled in the art, for example, a slightly rough surface, or an anti-slip sheet may be attached thereto.

In addition, the multistage bearing vertical clamp provided by the utility model can be matched with the rotating shaft of the vacuum coating device, so that rotation and revolution can be realized, and the target base distance between the magnet and the target on the same ring can be ensured.

In a more specific embodiment, the dimensions indicated in FIG. 1 are specifically exemplified. The diameter of the upper opening of the vertical diagonal column 1 is set as D7, and the diameter of the lower opening is set as D8. The inclined surface (i.e., the outer side surface in the circumferential direction) of the vertical diagonal column 1 has an angle θ with the bottom surface, and is required to be not less than 60 °. The outer surface of the vertical diagonal column 1 is respectively sleeved with rings (i.e. three placement rings 2 are sleeved together, meanwhile, it should be noted that, here, each placement ring 2 adopts an outer diameter and an inner diameter to describe the specification thereof, i.e. the inner diameter is the diameter of the side surface, which is attached to the outer surface of the vertical diagonal column 1, of the placement surface 3 along the radial direction, while the outer diameter is the diameter of the side surface, which is far away from the vertical diagonal column 1, of the placement surface 3 along the radial direction, the inner diameter is shown in fig. 1, the outer diameter is shown in fig. 3), the thickness (i.e. the height along the axial direction of the vertical diagonal column 1) of the placement rings 2 must not be less than 1mm, so as to avoid high-temperature deformation, and the difference between the outer diameter and the inner diameter needs to be greater than 3mm. Specifically, as shown in fig. 1, the distance between D2 and D4 (i.e., the distance between the lowermost placement ring 2 and the middle placement ring 2) is H2, the distance between D4 and D6 (i.e., the distance between the uppermost placement ring 2 and the middle placement ring 2) is H1, and the values of H1 and H2 need to be 3mm higher than the sample height to leave a certain placement space for the magnet to be plated.

Further, as shown in fig. 4, in order to make the placement of the magnets to be plated more stable, a vertical back ring 4 may be further disposed on the vertical diagonal column 1, where a side surface of the vertical back ring 4 facing away from the vertical diagonal column 1 is formed as an abutment surface 5 capable of contacting with the workpiece to be plated. Namely, the bottom surface of the placed magnet to be plated is contacted with the placing surface 3, and the back surface of the placed magnet can be contacted with the leaning surface 5, so that the whole contact surface is increased, the stress surface of the magnet to be plated is improved, and the problems of shaking and the like are avoided.

A specific embodiment of the present utility model will be described below with reference to specific dimensions.

The utility model provides a multistage bearing vertical clamp for vacuum coating. As shown in fig. 1, the umbrella-shaped vertical inclined column mainly comprises an umbrella-shaped main body part (namely a vertical inclined column 1) and an accessory part (namely a plurality of placing rings 2), and is manufactured by adopting high-quality 304 stainless steel. The flare cone of the body portion has an upper mouth diameter (i.e., D7) of 20mm and a lower mouth diameter (i.e., D8) of 100mm and a height of about 69mm. The included angle between the inclined plane and the bottom surface is 60 degrees. The outer surface of the main body part is respectively sleeved with a circular ring (namely a placing ring 2) with the outer diameter and the inner diameter of 105mm and 99mm, 75mm and 69mm and 49mm and 43mm respectively, and the thickness of the circular ring is 2mm. Based on the above, the fixture can be used for vacuum coating of magnetic materials with the height of not more than 20 mm. In addition, the inner diameter of each ring can be appropriately increased to reduce the distance between rings, thereby increasing the number of rings, and the magnet loading can be further increased. In summary, the utility model greatly improves the universality and the flexibility of the vacuum coating clamp, and reduces the limitation of the clamp to the shape and size diversity of the sintered NdFeB magnet.

While the utility model has been described in detail in the foregoing general description and specific examples, it will be apparent to those skilled in the art that modifications and improvements can be made thereto. Accordingly, such modifications or improvements may be made without departing from the spirit of the utility model and are intended to be within the scope of the utility model as claimed.
