Description

Technical Field

[0001] This utility model belongs to the field of jig technology, specifically relating to a jig with single-sided coating for spare parts. Background Technology

[0002] Vacuum coating is a method of applying a coating layer to the surface of a product. A fixture is a tool used to help position the parts to be coated. Existing fixtures generally use elastic elements to hold the parts in place and place them in the coating machine to facilitate coating. For example, the applicant's previous patent application, publication number CN219059113U, patent name: A Vacuum Coated Product and Fixing Bracket Installation Structure, uses hook springs at the top and bottom ends to fix the parts between them. However, when this fixture is used, both sides of the parts are coated during the coating process, while some parts only need to be coated on one side. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a single-sided coating fixture for spare parts, which facilitates single-sided coating of spare parts.

[0004] Technical solution: To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A single-sided coating fixture for spare parts includes a base plate and a positioning block disposed on the base plate. The positioning block includes a limiting frame connected to the base plate and a limiting block located within the area enclosed by the limiting frame. A slot for locking the spare parts is formed between the limiting frame and the limiting block. An anti-slip pad is connected to the limiting block. When the spare parts are locked in the slot, the spare parts are pressed against the anti-slip pad.

[0006] Furthermore, the anti-slip pad includes a first pad located within the slot and a second pad located on the front of the limiting block.

[0007] Furthermore, the back of the anti-slip mat is connected to the limiting block, and the front of the anti-slip mat is provided with a textured fiber layer.

[0008] Furthermore, a cavity is formed between the limiting block and the base plate, the limiting block is provided with a first through hole communicating with the cavity, and the base plate is provided with a second through hole communicating with the cavity.

[0009] Furthermore, the limiting frame is provided with a first notch and a second notch.

[0010] Furthermore, the height of the limiting frame is higher than the height of the limiting block.

[0011] Furthermore, the limiting frame is a rectangular frame or a circular frame, and the limiting block is a rectangular block or a circular block.

[0012] Furthermore, multiple positioning blocks are provided, and the multiple positioning blocks are arrayed on the base plate.

[0013] Furthermore, the fixture also includes an intermediate shaft and a connecting piece connected to the intermediate shaft, and the base plate is connected to the connecting piece.

[0014] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0015] 1. By setting a base plate and positioning blocks, the parts can be conveniently fixed and limited. When the parts are stuck in the slot, the back of the parts are against the limiting block, which makes it convenient to coat only the front side during coating.

[0016] 2. Two symmetrical notches are provided on the limiting frame to facilitate the retrieval of parts;

[0017] 3. The limiting block is connected to an anti-slip pad, which includes a first pad and a second pad. The first pad is located in the slot, and the second pad is located on the front of the limiting block. When the part is stuck in the slot, it squeezes the first pad. The first pad prevents the part from moving outward. The second pad can increase the static friction of the part moving left and right, preventing the part from sliding up and down or left and right. During the coating process, it can prevent the part from sliding and falling, ensuring the coating effect.

[0018] 4. By setting the first through hole, a cavity is formed between the limiting block and the base plate. The first through hole is connected to the cavity, and the second through hole on the base plate is connected to the cavity. When the parts are stuck on the positioning block, the air pressure on both sides is balanced, making it easy to pick up. Attached Figure Description

[0025] The present invention will be further illustrated below with reference to specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0026] like Figure 1 , Figure 5 and Figure 6 As shown, a single-sided coating fixture for spare parts includes a base plate 1, a positioning block, an intermediate shaft 6, and connecting pieces 7. The intermediate shaft 6 is a vertically arranged shaft. The connecting piece 7 includes a first piece 71 and a second piece 72, both of which are U-shaped pieces. The first piece 71 and the second piece 72 are arranged vertically to form a cross shape. There are two connecting pieces 7, one above the other, on the intermediate shaft 6. The position of the connecting piece 7 is determined by two locking nuts, and the distance between the two connecting pieces corresponds to the height of the base plate 1. The middle part of the first piece 71 and the second piece 72 has a through hole corresponding to the intermediate shaft 6 to facilitate the passage of the intermediate shaft 6. There are four base plates 1, which surround the intermediate shaft 6 and the connecting pieces 7. The upper and lower ends of the base plates 1 are respectively connected to one side of the first piece 71 or the second piece 72 by first bolts 73, so that the four base plates 1 are connected to the connecting pieces 7. In use, the intermediate shaft 6 is placed in the coating machine, and the drive structure inside the coating machine drives the intermediate shaft 6 to rotate slowly (existing coating machines and rotary drive structures). The intermediate shaft 6 drives the four base plates 1 to rotate slowly through the connecting piece 7. The intermediate shaft 6 and the connecting piece 7 are both made of metal, while the base plates 1 and the positioning blocks are both made of plastic.

[0027] like Figure 1 , Figure 2 and Figure 3As shown, the positioning blocks are set on the base plate 1. There are multiple positioning blocks, which are distributed in a rectangular array on the base plate 1. In this embodiment, each base plate 1 has two columns of positioning blocks. The positioning block includes a limiting frame 2 and a limiting block 3. In this embodiment, the part to be coated is rectangular. The rectangular part needs to be coated on the front side. Therefore, in this embodiment, the limiting frame 2 is a rectangular frame and the limiting block 3 is a rectangular block. The lower end of the limiting frame 2 is connected to the base plate 1. The limiting block 3 is located within the area enclosed by the limiting frame 2. The lower end of the limiting block 3 is also connected to the base plate 1. A slot 201 is formed between the limiting frame 2 and the limiting block 3. The shape of the slot 201 corresponds to the shape of the frame on the back of the part. The slot 201 is used to hold the part. The height of the limiting frame 2 is higher than the height of the limiting block 3. When the part is held in the slot 201, the back of the part is close to the surface of the limiting block 3, and the front of the part is flush with the top of the limiting frame 2, which facilitates coating on one side of the front of the part in the coating machine. The limiting frame 2 is provided with a first notch 21 and a second notch 22. The first notch 21 and the second notch 22 are located on both sides of the limiting frame 2 and are symmetrically arranged. The first notch 21 and the second notch 22 make it convenient for the back of the parts to be placed into the card slot 201, and after coating, it is also convenient to remove the parts by using the index finger and thumb with the first notch 21 and the second notch 22.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, an anti-slip pad 4 is connected to the limiting block 3. The back of the anti-slip pad 4 is attached to the upper surface of the limiting block 3 with double-sided adhesive. The front of the anti-slip pad 4 is provided with a textured fiber layer 401, which is a conventional curled plastic fiber. The anti-slip pad 4 includes a first pad 41 and a second pad 42. The first pad 41 is located in the slot 201, and the second pad 42 is located on the front of the limiting block 3. In this embodiment, the anti-slip pad 4 uses a textured surface with Velcro. When the part is stuck in the slot 201, the back of the part presses on the anti-slip pad 4, and the part in the slot 201 also squeezes the first pad 41 of the anti-slip pad 4. The first pad 41 can increase the static friction when the part moves outward, thereby preventing the part from moving outward. The second pad 42 can increase the static friction when the part moves left and right, preventing the part from sliding up and down or left and right. When the part is coated in the coating machine, the part rotates slowly. The anti-slip pad 4 can prevent the part from sliding and falling, ensuring the coating effect.

[0029] like Figure 2 , Figure 3 and Figure 4As shown, a cavity 101 is formed between the limiting block 3 and the base plate 1. The limiting block 3 is provided with a first through hole 31 communicating with the cavity 101, and the base plate 1 is provided with a second through hole 11 communicating with the cavity 101. By setting the first through hole 31, the cavity 101 and the second through hole 11, when the parts are stuck in the slot 201, the air pressure on the front and back is the same. When it is necessary to remove them, there will be no difference in air pressure on both sides due to the complete sealing of the back, which makes it convenient to take out the parts.

[0030] like Figure 1 and Figure 2 As shown, the four corners of the limiting block 3 are also provided with functional slots. The functional slots are rectangular. The functional slots at the four corners of the limiting block 3 can facilitate slight deformation of the four corners of the limiting block 3, making it easy to hold the parts in place. At the same time, the limiting block 3 will not exert excessive pressure on the parts, thus protecting the parts and making it easy to pick them up.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
