Description

Technical Field

[0001] This utility model relates to the field of parts processing, and in particular to a fixing device for engraving hexagonal screws. Background Technology

[0002] With the advancement of industrial manufacturing technology, the requirements for component marking are becoming increasingly stringent. Hex screws, as a common fastener, are widely used in machinery, electronics, and other fields. To meet the needs of product traceability and personalization, marking or numbering the surface of hex screws has become particularly important. However, traditional hand tools have the following problems when engraving hex screws: 1. Due to the small size of hex screws, especially their unique head shape, it is difficult to ensure that the screw does not rotate or shift during the engraving process, directly affecting the quality of the engraving; 2. Manual operation is easily affected by factors such as hand tremors, leading to problems such as misalignment and uneven depth of engraving, especially noticeable with miniature hex screws; 3. Traditional hand tools are usually only suitable for hex screws within a specific size range. When encountering screws of different sizes, special clamps are often required, increasing cost and complexity; 4. Each time a different size hex screw is changed, the tool needs to be readjusted, which is time-consuming and laborious, reducing overall work efficiency. Utility Model Content

[0003] The present invention aims to provide a fixing device for engraving hexagonal screws, so as to solve the problem of inconvenience in fixing hexagonal screws for engraving in the prior art.

[0004] The hexagonal screw engraving fixing device in this solution includes a fixing plate, on which holes of various diameters are evenly distributed, and each hole is provided with a slot that matches the head of the hexagonal screw.

[0005] The working principle and beneficial effects of this solution are as follows: When using this device, the operator only needs to pass the threaded end of the hexagonal screw directly through the hole in the fixing plate. After the threaded end of the screw passes through the hole, the head of the screw is located in the slot. The slot is cleverly designed, and its internal shape perfectly matches the head of the hexagonal screw, ensuring that the screw can be firmly locked in place and preventing any unnecessary movement or rotation. This fixing method is not only simple and intuitive to operate, but also has a compact structure, allowing for quick screw clamping without complicated adjustment steps. Because the fixing plate has various holes of different diameters, multiple screws can be transferred to the engraving machine position at once, achieving efficient one-time engraving operations. This not only saves time and labor costs, but also improves production efficiency, and is especially suitable for small screws that require frequent engraving; in addition, because the diameters of the holes are different, the diameters of the slots set outside the holes are also different, which can just fix screws of different sizes.

[0006] Furthermore, the slot consists of two straight plates and two inclined plates. The two inclined plates are connected opposite each other, and the two straight plates are fixed to the two inclined plates respectively. The two straight plates are located on both sides of the hole. This slot design allows it to be used with the head of a hexagonal screw, so that the head of the hexagonal screw can be more securely fixed in the slot.

[0007] Furthermore, a bracket is provided at the bottom of the fixing plate, and a pressure plate is slidably connected to the bracket, with the pressure plate located directly below the fixing plate. After the engraving of the hexagonal screws is completed, the entire device is inverted, and some of the hexagonal screws fall directly to be collected. Then, the pressure plate is slid towards the fixing plate, and the pressure plate will directly squeeze the screws that have not fallen out, disengaging them from the slots, so that all the hexagonal screws fall to be collected.

[0008] Furthermore, the slot is made of a flexible material. This flexibility helps prevent damage to the screw. Attached Figure Description

[0011] The following detailed explanation illustrates the specific implementation methods:

[0012] The reference numerals in the accompanying drawings include: 1. Fixing plate; 2. Large hole; 3. Small hole; 4. Medium hole; 5. Straight plate; 6. Inclined plate; 7. Bracket; 8. Pressure plate.

[0013] The basic implementation examples are as follows: Figure 1 and Figure 2 As shown: A fixing device for engraving hexagonal screws includes a fixing plate 1. The fixing plate 1 has three different diameter holes evenly distributed on it: large hole 2, medium hole 4, and small hole 3. Each hole has a slot that matches the head of the hexagonal screw. The slot consists of two straight plates 5 and two inclined plates 6. Both the straight plates 5 and the inclined plates 6 are made of flexible material. The two inclined plates 6 are connected to each other. The two straight plates 5 are fixed to the two inclined plates 6 respectively. The two straight plates 5 are located on both sides of the hole. The bottom of the fixing plate 1 has a bracket 7. The two opposite sides of the bracket 7 have vertical sliding grooves. A pressure plate 8 is slidably connected in the sliding groove. The pressure plate 8 has a protrusion that slides in the sliding groove. The pressure plate 8 is located directly below the fixing plate 1.

[0014] The working principle and beneficial effects of this solution are as follows: When using this device, the operator only needs to pass the threaded end of the hexagonal screw directly through the hole on the fixing plate 1. After the threaded end of the screw passes through the hole, the head of the screw is located in the slot. The slot is designed to precisely match the shape of the hexagonal screw, limiting its position. This ingenious slot design ensures that the internal shape perfectly matches the head of the hexagonal screw, guaranteeing that the screw is securely held in place and preventing any unnecessary movement or rotation. This fixing method is not only simple and intuitive to operate, but also ingeniously structured, allowing for quick screw clamping without complex adjustment steps. Because the fixing plate 1 has various holes of different diameters, multiple screws can be transferred to the engraving machine position at once, achieving efficient one-time engraving operations. This not only saves time and labor costs but also improves production efficiency, especially suitable for small screws that require frequent engraving; in addition, because the diameter of the holes is different, the diameter of the slots set outside the holes is also different, which can just fix screws of different sizes; after the engraving of the hexagonal screws is completed, the whole device is inverted, some of the hexagonal screws fall directly to be collected, and then the pressure plate 8 is slid toward the fixing plate 1, the pressure plate 8 will directly squeeze the screws that have not fallen out, and disengage them from the slots, so that all the hexagonal screws fall to be collected.
