Description

Technical Field

[0001] This utility model relates to the field of mechanical design, and in particular to a coating rack fixing device with adjustable size. Background Technology

[0002] To enhance the strength, wear resistance, and corrosion resistance of materials, coated yarns are required. These coated yarns can be fixed to a coating rack using welding, binding, or other methods to form a unified structure. Since the coated yarns on the coating rack are typically handled and produced in a dust-free and sterile environment, they usually do not come into contact with objects to avoid contamination. Removing yarns from the coating rack requires two people: one to lift the rack and the other to remove the yarn. When only one person is available, it is impossible to remove the yarn according to the operating procedures, thus affecting production progress. Therefore, some coating rack fixing devices have been developed, which support and clamp the coating rack by engaging with clamps on it. However, the various length and width specifications of coating racks result in inconsistent clamp spacing, necessitating the manufacture of devices with different sizes to accommodate different clamp sizes, leading to resource waste. Therefore, a new type of coating rack fixing device needs to be designed to accommodate coating racks of different sizes. Utility Model Content

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This utility model proposes a coating rack fixing device with adjustable dimensions. The coating rack is fixed by a support assembly, and the distance between the support columns in the support assembly is adjusted by a distance control assembly. Specifically, the distance control assembly includes a lower fixing plate, a guide plate, and a linkage mechanism stacked sequentially. The guide plate has multiple guide grooves, each radially arranged at equal angular intervals with the center of the guide plate as its center. The linkage mechanism includes multiple sets of mechanical rods matching the number of guide grooves. Each set of mechanical rods includes a first link and a second link.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0032] Example:

[0033] like Figure 8As shown, the coating wire 8 is fixed on the coating frame 7, forming an integral structure. The coating frame 7 can be fixed by a device to enable single-person wire picking operation. However, since the coating frame 7 has many different sizes and the distance of its claws 9 is not uniform, it is necessary to manufacture various sizes of fixing devices to match the claws 9 with different distances.

[0034] This embodiment provides a size-adjustable coating rack fixing device, including a distance control component and a support component. The coating rack 7 is fixed by the support component, and the distance control component adjusts the distance between each support column in the support component to adapt to coating racks 7 of different sizes.

[0035] like Figure 1 The distance control assembly includes a lower fixed plate 1, a guide plate 2, and a linkage mechanism 3 stacked sequentially. The guide plate 2 has four guide grooves 5, each radially arranged with the center of the guide plate 2 as its center, and the included angle between adjacent guide grooves 5 is 90°. The linkage mechanism 3 includes four sets of mechanical rods, such as... Figure 2 As shown, each set of mechanical rods includes a first connecting rod 301 and a second connecting rod 302. One end of all the first connecting rods 301 is coaxially connected to the lower fixed plate 1 and the guide plate 2 through the axial assembly 4, and the other end is rotatably connected to one end of the corresponding second connecting rod 302. A locking device 303 is provided at the connection between the first connecting rod 301 and the second connecting rod 302. The locking device 303 can be a screw.

[0036] Axial assembly 4 includes a fixed shaft 401, a bearing 402, and a nut 403, such as Figure 3 As shown, one end of the fixed shaft 401 is fixed to the center of the lower fixed plate 1, and the other end protrudes from the center of the guide plate 2. The bearing 402 is located above the guide plate 2 and is fitted onto the fixed shaft 401. The top of the bearing 402 is locked by a nut 403 to prevent the fixed shaft 401 from moving longitudinally. In a preferred embodiment, the end of each first connecting rod 301 that is not connected to the second connecting rod 302 is fixed to the edge of a ring so that all the first connecting rods can rotate synchronously at equal angles. The ring is fitted over the bearing 402, and the ring is locked to the bearing 402 from the side by a second screw 404.

[0037] The support components include four support columns 6, such as Figure 4 As shown, the bottom end of each support column 6 is countersunk and locked in the guide groove 5, with both sides of the locked portion conforming to the shape of the guide groove 5. The other end of the support column 6 protrudes from the end of the second connecting rod 302 that is not connected to the first connecting rod 301, and is locked in place by the third screw 304. The width of the end of the second connecting rod 302 that is not connected to the first connecting rod 301 is greater than the width of the guide groove 5, and the length of the guide groove 5 is equal to or slightly less than the sum of the lengths of the first connecting rod 301 and the second connecting rod 302. The lower fixing plate 1 and the guide plate 2 are locked in place by the first screw 101 to prevent the support column 6 from moving up and down during sliding.

[0038] The top of the support column 6 is used to fix the coating rack 7, as in one embodiment, such as Figure 5 As shown, the top of the support column 6 is provided with a cross groove that matches the shape of the claw 9 of the coating frame 7; in another embodiment, the end of the support column 6 is provided with a gripper to grip and fix the coating frame 7.

[0039] When the linkage mechanism is in the open state, such as Figure 7 As shown in (7a), the support column 6 is located at the end of the guide groove 5 away from the axial assembly, and the spacing between the support columns 6 is the largest. When the size of the coating frame 7 is smaller than this spacing, the locking device 303 at the connection between the first link 301 and the second link 302 is first loosened, and then the first link 301 is pushed to rotate clockwise or counterclockwise, thereby driving the second link 302 to move the support column 6 toward the axis. Figure 7 As shown in (7b), reduce the spacing between each support column 6. After determining the support column spacing, tighten the locking device 303, as shown. Figure 6 As shown, the coating holder 7 is fixed.

[0040] The aforementioned device has a simple structure and can be used to support and clamp coating racks 7 of different sizes. A single person can remove the coating wire 8 from the coating rack 7, which improves work efficiency. Since the coating rack 7 in this embodiment is rectangular and requires four-point control, only four guide grooves 5, four sets of mechanical rods, and four support columns 6 are designed. When the coating rack 7 has other shapes, the number of guide grooves 5 and other components can be designed accordingly to control the distance between the support columns 6. In a preferred embodiment, the axial component 4 can be rotated by a motor, thereby driving the linkage mechanism 3 to rotate, achieving intelligent and automated adjustment.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
