Description

Technical Field

[0001] This utility model relates to the field of auxiliary coating technology, and in particular to a hanger and rotating hanger assembly for vacuum coating of spoon-shaped workpieces. Background Technology

[0002] Vacuum coating is a method in which a metallic or non-metallic material is heated under high vacuum conditions, causing it to evaporate and condense onto the surface of a workpiece to form a thin film. When performing vacuum coating on a spoon-shaped workpiece, the spoon-shaped tool needs to be suspended in the air. Utility Model Content

[0003] The purpose of this utility model is to provide a rotating hanger assembly to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: This utility model provides a hanger for vacuum coating of spoon-shaped workpieces, which is used to support spoon-shaped workpieces. The hanger includes: a cantilever; and a supporting arc strip connected to the end of the cantilever. The supporting arc strip is bent to form a semi-circle. The plane of the semi-circle is parallel to the cantilever. The middle part of the supporting arc strip is bent at the two ends. The spoon-shaped workpiece can be supported by the supporting arc strip.

[0005] This technical solution has at least the following beneficial effects: When the spoon-shaped workpiece is supported on the supporting arc strip, due to the bent design of the supporting arc strip, the supporting arc strip contacts the spoon-shaped workpiece at three points when the spoon-shaped workpiece is placed on the supporting arc strip. This facilitates the placement of the spoon-shaped workpiece and provides stable support for it. At the same time, the small contact area between the spoon-shaped workpiece and the supporting arc strip reduces the impact of the supporting arc strip on the spoon-shaped workpiece during vacuum coating, thereby ensuring the vacuum coating effect of the spoon-shaped workpiece.

[0006] As a further improvement to the above technical solution, the bending axis of the supporting arc strip is parallel to the cantilever. When the spoon-shaped workpiece is placed on the supporting arc strip, it is easier to judge the stability of the spoon-shaped workpiece.

[0007] As a further improvement to the above technical solution, the curvature at both ends of the supporting arc strip is greater than that in the middle. This allows for a suitable reduction in the overall width of the supporting arc strip, facilitating the placement and adjustment of the spoon-shaped workpiece.

[0008] As a further improvement to the above technical solution, the cross-section of the supporting arc strip is circular. This further reduces the impact of the supporting arc strip on the spoon-shaped workpiece.

[0009] As a further improvement to the above technical solution, the cantilever and the supporting arc strip are integrally formed. This facilitates the production and manufacturing of the hanger and improves the connection strength between the cantilever and the supporting arc strip.

[0010] As a further improvement to the above technical solution, a transition arc strip connects the supporting arc strip and the cantilever.

[0011] This utility model also provides a rotating fixture assembly, including a support frame and the aforementioned fixture for vacuum coating of spoon-shaped workpieces. Multiple fixtures are arranged in a ring around the support frame, and a hollow cylinder is located at the center of the support frame. This allows for batch coating of spoon-shaped workpieces, and the hollow cylinder can be threaded onto a rotating shaft, facilitating the installation of the rotating fixture assembly and the stacking of multiple rotating fixture assemblies. This facilitates the handling and placement of multiple spoon-shaped tools, saving processing space during vacuum coating.

[0012] As a further improvement to the above technical solution, the end of the cantilever away from the supporting arc strip is welded to the support frame, and the cantilever is perpendicular to the axis of the hollow cylinder. This ensures the stability of the connection between the cantilever and the support frame.

[0013] As a further improvement to the above technical solution, the plane containing the semi-annular shape is perpendicular to the axis of the hollow cylinder. This facilitates the placement of the spoon-shaped workpiece.

[0014] As a further improvement to the above technical solution, the support frame includes an outer ring and a support rod, one end of which is connected to the outer ring and the other end to the hollow cylinder. The structure is simple and stable, with low cost and good economic efficiency. Attached Figure Description

[0023] Reference Figure 1 A fixture 100 for vacuum coating of spoon-shaped workpieces includes a cantilever 110 and a supporting arc strip 120. One end of the cantilever 110 is connected to a transition arc strip 130, one end of which is tangential to the cantilever 110. The end of the transition arc strip 130 away from the cantilever 110 is connected to one end of the supporting arc strip 120. In other words, the cantilever 110, the transition arc strip 130, and the supporting arc strip 120 are connected sequentially. The cantilever 110, the transition arc strip 130, and the supporting arc strip 120 are integrally bent and formed, and all three have circular cross-sections, resulting in high overall strength of the fixture 100 and ease of manufacturing.

[0024] The supporting arc strip 120 is bent to form a semi-circular structure. The arc of the middle part of the supporting arc strip 120 is greater than the arc of the two ends of the supporting arc strip 120. In other words, the radius of the arc in the middle part of the supporting arc strip 120 is greater than the radius of the arc at the two ends of the supporting arc strip 120. The radius of the arc can be a fixed value at the middle and two ends of the supporting arc strip 120, or it can gradually decrease from the middle to the two ends of the supporting arc strip 120. This makes the supporting arc strip 120 an irregular circle.

[0025] The supporting arc strip 120 is bent at both its middle and two ends, forming three consecutive bent segments: a first segment 121, a second segment 122, and a third segment 123. One end of the first segment 121 connects to the transition arc strip 130, and the first segment 121, the transition arc strip 130, and the cantilever are all on the same plane, with the first segment 121 and the transition arc strip 130 being externally tangent. The end of the first segment 121 furthest from the transition arc strip 130 connects to one end of the second segment 122. The end of the second segment 122 furthest from the first segment 121 connects to one end of the third segment 123, and the end of the third segment 123 furthest from the second segment 122 is suspended. Both bending points of the supporting arc strip 120 are located at the ends with the smaller radius of the arc.

[0026] The bending angle between the first segment 121 and the second segment 122 is the same as the bending angle between the second segment 122 and the third segment 123. The midpoint of the supporting arc 120 and its two endpoints are all on the same supporting plane. The line connecting the bending point between the first segment 121 and the second segment 122 and the bending point between the second segment 122 and the third segment 123, i.e., the bending axis, is parallel to the length direction of the cantilever 110.

[0027] Generally, a spoon-shaped workpiece is a workpiece with a convex spherical surface. The end of the cantilever 110 away from the supporting arc 120 is fixed, making the supporting plane of the supporting arc 120 horizontal, allowing the convex spherical surface of the spoon-shaped workpiece to rest on the supporting arc 120. When the spoon-shaped workpiece is placed on the supporting arc 120, due to the bent design of the supporting arc 120, the supporting arc 120 contacts the spoon-shaped workpiece at three points, thus facilitating placement and stable support. Simultaneously, the small contact area between the spoon-shaped workpiece and the supporting arc 120 reduces the impact of the supporting arc 120 on the spoon-shaped workpiece during vacuum coating, thereby ensuring the vacuum coating effect on the spoon-shaped workpiece.

[0028] Reference Figure 2A rotating fixture assembly 200 includes the aforementioned fixture 100 for vacuum coating of spoon-shaped workpieces. The rotating fixture assembly 200 also includes a support frame 210 and a hollow cylinder 300. The hollow cylinder 300 is located at the center of the support frame 210. The support frame 210 includes an outer ring 220 and support rods 230. Four support rods 230 are provided, and one end of each of the four support rods 230 is uniformly fixed to the outer periphery of the hollow cylinder 300. The length direction of the support rods 230 is perpendicular to the axial direction of the hollow cylinder 300. The ends of the four support rods 230 away from the hollow cylinder 300 are all fixed to the outer ring 220, thereby forming a stable frame structure with the hollow cylinder 300, support rods 230, and outer ring 220. The outer ring 220 is formed by welding two circular rings with a circular cross-section. The two rings are in the same plane, and the inner diameter of one ring is the same as or close to the outer diameter of the other ring. In other embodiments, the support rod 230 may also be provided with two, three, or five rods, etc.

[0029] The rotating hanger assembly 200 includes multiple hangers 100. The cantilever 110 of each hanger 100 has its end away from the supporting arc strip 120 welded to the outer ring 220. The length direction of the cantilever 110 is perpendicular to the axis of the hollow cylinder 300. The multiple hangers 100 are evenly distributed around the outer ring 220. The supporting plane formed by the supporting arc strip 120 is parallel to the plane of the outer ring 220; or, more accurately, the supporting plane formed by the supporting arc strip 120 is perpendicular to the axis of the hollow cylinder 300.

[0030] The cantilever 110 has a length between 35 mm and 55 mm, and the outer ring 220 has a diameter between 110 mm and 140 mm. The width of the supporting arc 120 perpendicular to the length of the cantilever 110 is between 25 mm and 35 mm. A rotating hanger assembly 200 may have 16 hangers 100, thereby creating a suitable spacing between adjacent hangers 100 to facilitate the placement and removal of spoon-shaped workpieces. In other embodiments, the supporting planes in adjacent hangers 100 may be staggered vertically along the axial direction of the hollow cylinder 300.

[0031] When the hollow cylinder 300 is fitted onto the suitable rotating shaft, the spoon-shaped workpiece can be placed on the support arc strip 120, thereby suspending the spoon-shaped workpiece for vacuum coating treatment.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
