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 sheared workpieces. Background Technology

[0002] Vacuum coating is a method that involves heating metallic or non-metallic materials under high vacuum conditions, causing them to evaporate and condense onto the surface of a workpiece to form a thin film. When performing vacuum coating on sheared workpieces, the shearing tool needs to be suspended in mid-air. Utility Model Content

[0003] The purpose of this utility model is to provide a hanger and a rotating hanger assembly for vacuum coating of sheared workpieces, so as 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 sheared workpieces, used to suspend sheared workpieces. The sheared workpieces have hanging holes. The hanger includes: a limiting piece with a limiting groove; a support arm, one end of which is fixed to the limiting piece, and the other end is connected to a hook strip that can pass through the hanging hole. The hook strip spans the limiting groove, and a clearance gap is provided between the hook strip and the limiting piece.

[0005] This technical solution has at least the following beneficial effects: When vacuum coating is required on a cut workpiece, the cut workpiece is first hung on the hook strip through the hanging hole, with the width side of the cut workpiece in the clearance gap. When the cut workpiece corresponds to the limiting groove, the cut workpiece can be released, allowing it to hang naturally and be in the limiting groove. This prevents the cut workpiece from falling off the hook strip and also keeps the cut workpiece in a stable suspended state, which is convenient for vacuum coating treatment of the cut workpiece.

[0006] As a further improvement to the above technical solution, the support arm is bent in the middle to form a first section and a second section. The first section is arranged parallel to the limiting piece, and the second section is arranged perpendicular to the limiting piece. The second section is connected to the hook strip. This ensures the supporting performance of the hook strip.

[0007] As a further improvement to the above technical solution, the support arm is bent in the middle to form a first section and a second section. The first section is arranged perpendicularly to the limiting piece, and the second section is arranged parallel to the limiting piece. The second section is connected to the hook strip. This reduces the impact of the second section on the vacuum coating of the sheared workpiece.

[0008] As a further improvement to the above technical solution, the first segment is welded to the limiting piece to facilitate the connection between the support arm and the limiting piece.

[0009] As a further improvement to the above technical solution, both sides of the opening of the limiting groove are provided with rounded chamfers. This facilitates the embedding of the sheared workpiece into the limiting groove and improves the suspension efficiency.

[0010] Another aspect of this utility model provides a rotating fixture assembly, including a support frame and the aforementioned fixture for vacuum coating of sheared workpieces. Multiple fixtures are arranged in a ring around the support frame, and a hollow column is provided in the center of the support frame. Inserting the hollow column into a rotating shaft facilitates batch processing of multiple fixtures.

[0011] As a further improvement to the above technical solution, multiple limiting pieces are fixedly connected to each other to form an outer ring piece, and the support frame is connected to the outer ring piece. This facilitates manufacturing and reduces costs.

[0012] As a further improvement to the above technical solution, the support frame includes an inner ring plate fixed to the outside of the hollow column, and a support plate is connected between the outer ring plate and the inner ring plate. This ensures the stability of the support frame.

[0013] As a further improvement to the above technical solution, the outer ring plate, the inner ring plate, and the support plate are integrally molded, which ensures the overall strength of the support frame.

[0014] As a further improvement to the above technical solution, the outer ring plate, the inner ring plate, and the support plate are all arranged flush on both sides, which facilitates manufacturing. Attached Figure Description

[0023] The shearing workpiece, such as one of the pieces that make up a cross-shaped pair of scissors, has a hanging hole. The hanging hole can be a structure provided in the shearing workpiece for assembling into scissors, or it can be a structure specifically used for suspending the shearing workpiece during vacuum coating.

[0024] Example 1:

[0025] Reference Figure 1This embodiment provides a hanger 100 for vacuum coating of sheared workpieces. The hanger 100 includes a limiting plate 110, a support arm 120, and a hook strip 130. The limiting plate 110 is a thin sheet structure with a limiting groove 111 formed on its front side, extending through both the upper and lower sides of the limiting groove 111. The support arm 120 is positioned slightly to the left of the upper side of the limiting plate 110. One end of the support arm 120 is fixed to the limiting plate 110, and the other end is connected to the hook strip 130. Under the support of the support arm 120, a preset clearance gap 140 is provided between the hook strip 130 and the limiting plate 110. The size of the clearance gap 140 needs to be determined according to the width of the sheared workpiece and the position of the hanging hole. The hook strip 130 is horizontally positioned across the limiting groove 111. This means that, when projected onto the plane of the limiting piece 110, the hook strip 130 traverses the middle of the limiting groove 111, and its length is perpendicular to the length of the limiting groove 111. Alternatively, the limiting groove 111 longitudinally traverses the middle of the hook strip 130. Both the hook strip 130 and the support arm 120 have circular cross-sections.

[0026] The end of the limiting piece 110 away from the limiting groove 111 is fixed. When the cut workpiece needs vacuum coating treatment, it can be hung on the hook strip 130, that is, the cut workpiece is inserted into the hook strip 130 in a horizontal posture. The hook strip 130 is inserted into the hanging hole. When the cut workpiece reaches the middle position of the hook strip 130, it is released. Under the imbalance of gravity on both sides, the cut workpiece changes its horizontal posture to a vertical posture, so that the cut workpiece is in the limiting groove 111. The two sides of the limiting groove 111 can restrict the cut workpiece, so that the cut workpiece is not easy to fall out of the hook strip 130, ensuring the suspension stability of the cut workpiece. The width of the limiting groove 111 is slightly larger than the thickness of the cut workpiece to ensure the smooth change of the cut workpiece's posture, and at the same time, it can also reduce the influence of the side wall of the limiting groove 111 on the vacuum coating of the cut workpiece surface.

[0027] Both sides of the opening of the limiting groove 111 are provided with rounded chamfers. When the sheared workpiece changes its posture and enters the limiting groove 111, the rounded chamfers can guide the sheared workpiece, making it easier for the sheared workpiece to enter the limiting groove 111 and facilitating the placement of the sheared workpiece.

[0028] The support arm 120 is bent at its middle to form a first segment 121 and a second segment 122. The connection point between the first segment 121 and the second segment 122 is the bend point, and the length direction of the first segment 121 is perpendicular to the length direction of the second segment 122. The first segment 121 is parallel to the plane of the limiting piece 110 and is fixed to the limiting piece 110 by welding. The end of the second segment 122 furthest from the first segment 121 is integrally connected to the hook strip 130. It can be understood that the support arm 120 and the hook strip 130 are integrally formed through a bending process. The length direction of the second segment 122 is perpendicular to the plane of the limiting piece 110, while the length direction of the first segment 121 is perpendicular to the length direction of the hook strip 130. This provides the support arm 120 with more stable and reliable support for the hook strip 130.

[0029] Reference Figure 2 This embodiment also provides a rotating hanger assembly 200, which includes multiple hangers 100 and a support frame 210. The multiple hangers 100 are arranged in a ring around the outer periphery of the support frame 210. Specifically, the support frame 210 includes an inner ring piece 211 and a support piece 212. A hollow column 220 is provided at the center of the inner ring piece 211. One end of the hollow column 220 passes through the inner ring piece 211 and is flush with the inner ring piece 211.

[0030] Six support pieces 212 are evenly distributed around the outer side of the inner ring piece 211. All the limiting pieces 110 in the hangers 100 are interconnected to form an outer ring piece 300. The opening of the limiting groove 111 faces away from the hollow column 220. It can be understood that all the limiting pieces 110 are integrally formed from the outer ring piece 300. The end of the support piece 212 away from the inner ring piece 211 is connected to the inner circumferential sidewall of the outer ring piece 300. The outer ring piece 300 and the inner ring piece 211 are concentrically distributed. The inner ring piece 211, the support piece 212, and the outer ring piece 300 are integrally formed, and both sides of the three are flush, meaning they have the same thickness. It can also be understood that the support piece 212 can be formed by opening fan-shaped holes in the entire circular ring piece, with the number of fan-shaped holes being the same as the number of support pieces 212.

[0031] In other embodiments, the support piece 212 can be set to 2 pieces, 3 pieces, 4 pieces, 5 pieces, etc., depending on the actual situation, and the number of hangers 100 matched on each support frame 210 is determined according to the actual size.

[0032] When multiple sheared workpieces need to be vacuum coated, the rotating hanger assembly 200 can be installed on the rotating shaft, with the hollow column 220 sleeved on the rotating shaft. Then, multiple sheared workpieces are suspended in the hanger 100, which can improve the efficiency of vacuum coating suspension treatment of sheared workpieces and thus improve the processing efficiency.

[0033] Example 2:

[0034] The difference between this embodiment and Embodiment 1 lies in the support arm 120 and the specific connections between the support arm 120 and the limiting piece 110 and the hook strip 130, respectively. In this embodiment, the support arm 120 is also bent in the middle and divided into a first segment 121 and a second segment 122. However, the first segment 121 of the support arm 120 is vertically fixed to the limiting piece 110, and the second segment 122 is connected to the end of the first segment 121 away from the limiting piece 110. The second segment 122 is parallel to the plane where the limiting piece 110 is located. It can be understood that the distance between the second segment 122 and the limiting piece 110 is the same as the distance between the hook strip 130 and the limiting piece 110.

[0035] 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.
