Description

Technical Field

[0001] This utility model relates to the field of vacuum coating technology, specifically a vacuum coating circular hole type hanger. Background Technology

[0002] The round hole type hanger uses its own round hole structure to hang workpieces, which can be adapted to the coating needs of workpieces with specific shapes (such as tubular or cylindrical) or those that require precise positioning.

[0003] Most of the currently used hangers are difficult to rotate and install. During use, if the hanger is difficult to rotate, the different surfaces of the workpiece cannot be evenly exposed to the coating source, resulting in uneven film thickness and poor product quality, thus reducing the practicality of the hanger. If the hanger is difficult to install, it will be unstable, causing the hanger to sway in multiple directions during rotation, which may cause it to fall off, thus reducing the installation stability of the hanger. Summary of the Invention

[0004] The purpose of this invention is to provide a vacuum coating circular hole type fixture to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum coating circular hole type hanger, including a hanger body, a rotating mounting mechanism is provided on the top of the hanger body, the rotating mounting mechanism includes a rotating rod, a rotating rod is provided on the top of the hanger body, a bearing is provided at the top of the rotating rod, a mounting plate is provided on the top of the bearing, and a threaded hole is opened inside the mounting plate.

[0006] As a preferred technical solution, the inner wall of the threaded hole is provided with a bolt, and the number of threaded holes is four.

[0007] As a preferred technical solution, a large gear is provided on the outer wall of the rotating rod, and a motor is provided at the bottom of the mounting plate.

[0008] As a preferred technical solution, the output shaft of the motor is connected to a motor shaft via a coupling, and a small gear is provided at the bottom end of the motor shaft.

[0009] As a preferred technical solution, the small gear and the large gear mesh with each other, and the vertical center line of the rotating rod coincides with the vertical center line of the hanging body.

[0010] As a preferred technical solution, the mounting plate is rectangular in shape, and the interior of the hanger body has a circular hole.

[0011] As a preferred technical solution, a ceramic ring is provided on the inner wall of the circular hole, and the shape and size of the ceramic ring match the shape and size of the circular hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of a rotating installation mechanism, can achieve the functions of rotating the hanger and fixing it in a specific position. During use, the hanger is fixed in a specific position through the cooperation of threaded holes and bolts. The motor drives the hanger to rotate, which can avoid the situation where the different surfaces of the workpiece are not evenly exposed to the coating source due to the difficulty in rotating the hanger, resulting in uneven film thickness and poor product quality. This ensures the practicality of the hanger and also avoids the situation where the hanger is unstable due to the difficulty in installing it, which could cause the hanger to sway in multiple directions during rotation and fall off. This ensures the installation stability of the hanger.

[0013] This invention, through the inclusion of a ceramic ring, can protect the workpiece. During use, the smooth surface of the ceramic ring protects the workpiece, preventing hard contact between the workpiece and the metal fixture, which is difficult to protect. This avoids the possibility of the tiny burrs and sharp edges on the inner wall of the metal scratching the workpiece surface. Additionally, the thermal expansion of the metal may cause thermal deformation and compression of the workpiece, thus ensuring the practicality of the fixture. Attached Figure Description

[0016] 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.

[0017] Example: Figure 1 and Figure 4 As shown, the present invention provides the following technical solution, including a hanging body 1, a rotating mounting mechanism 2 on the top of the hanging body 1, a circular hole 4 inside the hanging body 1, and a ceramic ring 3 on the inner wall of the circular hole 4.

[0018] Specifically: When the fixture body 1 is needed, it must first be installed and fixed in a specific installation position. The fixture body 1 is installed and fixed in the specific installation position by the set rotation installation mechanism 2. After installation, the fixture body 1 can be used to suspend the workpiece through the round hole 4. During suspension, the ceramic ring 3 inside the round hole 4 protects the workpiece. After hanging, the fixture body 1 needs to be rotated to improve the film thickness uniformity. The fixture body 1 is rotated by the set rotation installation mechanism 2 to improve the film thickness uniformity, thereby completing the work.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, a rotating mounting mechanism 2 is provided on the top of the hanger body 1. The rotating mounting mechanism 2 includes a rotating rod 201. The top of the rotating rod 201 is provided with a bearing 202. The top of the bearing 202 is provided with a mounting plate 203. The mounting plate 203 has threaded holes 204 inside. Bolts 205 are provided on the inner wall of the threaded holes 204. There are four threaded holes 204. A large gear 206 is provided on the outer wall of the rotating rod 201. A motor 207 is provided at the bottom of the mounting plate 203. The output shaft of the motor 207 is connected to a motor shaft 208 through a coupling. A small gear 209 is provided at the bottom of the motor shaft 208. The small gear 209 meshes with the large gear 206. The vertical center line of the rotating rod 201 coincides with the vertical center line of the hanger body 1. The mounting plate 203 is rectangular in shape.

[0020] Specifically: When the hanger body 1 is needed, it must first be installed and fixed in a specific installation position. At this point, the mounting plate 203 is placed against the specific position, and then the threaded hole 204 in the mounting plate 203 is aligned with the threaded hole 204 in the specific position. The bolt 205 is then rotated and inserted into the threaded hole 204 to fix the mounting plate 203 in the specific position, thereby fixing the hanger body 1 in the specific position, thus completing the installation and fixing work. After hanging, the hanger body 1 needs to be rotated to improve film thickness uniformity. At this time, the motor 207 is started, which drives the motor shaft 208 to start rotating. The motor shaft 208 drives the pinion 209 to start rotating, the pinion 209 drives the gear 206 to start rotating, the gear 206 drives the rotating rod 201 to start rotating, and the rotating rod 201 drives the fixture body 1 to start rotating, so that the fixture body 1 drives the workpiece to rotate slowly, so that all surfaces of the workpiece can be evenly exposed to the coating source, improving product quality. The bearing 202 can ensure that the mounting plate 203 will not rotate with the rotation of the rotating rod 201, thus completing the rotation work.

[0021] like Figure 1 and Figure 4 As shown, a ceramic ring 3 is provided on the inner wall of the circular hole 4, and the shape and size of the ceramic ring 3 match the shape and size of the circular hole 4.

[0022] Specifically, during suspension, the ceramic ring 3 inside the round hole 4 protects the workpiece, preventing the hanger body 1 from directly contacting the workpiece and causing the hanger body 1 to be affected by thermal expansion and squeeze the workpiece. At the same time, it prevents the tiny burrs inside the round hole 4 from scratching the workpiece, thus completing the protection work.

[0023] The working principle of this utility model is as follows: When the hanger body 1 is needed, it is first necessary to install and fix the hanger body 1 in a specific installation position. At this time, the mounting plate 203 is attached to the specific position, and then the threaded hole 204 in the mounting plate 203 is aligned with the threaded hole 204 in the specific position. Then, the bolt 205 is rotated and inserted into the threaded hole 204 to fix the mounting plate 203 in the specific position, thereby fixing the hanger body 1 in the specific position, thus completing the installation and fixing work. After installation, the hanger body 1 can be used. The workpiece is suspended by the round hole 4. During suspension, the ceramic ring 3 in the round hole 4 protects the workpiece and prevents the hanger body 1 from direct contact with the workpiece, so that the hanger body 1 is protected from damage. Thermal expansion causes pressure on the workpiece, while preventing tiny burrs in the round hole 4 from scratching the workpiece, thus completing the protective work. After hanging, the hanger body 1 needs to be rotated to improve the uniformity of the film thickness. At this time, the motor 207 is started, which drives the motor shaft 208 to rotate. The motor shaft 208 drives the pinion 209 to rotate, which drives the gear 206 to rotate. The gear 206 drives the rotating rod 201 to rotate, which drives the hanger body 1 to rotate. This causes the hanger body 1 to slowly rotate the workpiece, so that all surfaces of the workpiece are evenly exposed to the coating source, improving product quality. The bearing 202 ensures that the mounting plate 203 does not rotate with the rotating rod 201, thus completing the rotation work.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
